The crawler frame 20 extends in the front-rear direction X and protrudes before and after the axle 15.

  The actuator 25 operates the construction machine 1 and specifically travels the lower body 5. The actuator 25 is a hydraulic actuator that is supplied with oil and is driven, for example, a hydraulic motor. For example, two (a total of four) actuators 25 are provided in one crawler frame 20 (a total of two may be used). The actuator 25 is mounted on an end portion (for example, both end portions) of the crawler frame 20 in the front-rear direction X.

  The pipe 30 is a hydraulic pipe through which oil (pressure oil, hydraulic oil) flows. The pipe 30 supplies oil to the actuator 25 (transmits hydraulic power) from a power source (not shown) mounted on the upper swing body. The pipe 30 returns the oil discharged from the actuator 25 to a tank (not shown) mounted on the upper swing body. The piping 30 includes, for example, for the forward movement of the lower body 5, for backward movement, and for drain oil. The pipe 30 is mounted on the car body 10 and the crawler frame 20. The piping 30 is composed of a swivel joint 31, an in-car body piping 33, an elbow 35, a car body side port 39, a hose 40, a crawler frame side port 51, and an actuator piping in this order from the upstream side (upper swing body side). 53. The pipes 30 are provided symmetrically (symmetrically in the lateral direction Y of the lower main body 5) and symmetrically in the longitudinal direction X. In FIG. 1, only one of the left and right pipes 30 (the lower side in FIG. 1) is given the reference numerals of the components (31 to 53) of the pipe 30. In FIG. 1, only a part (a total of only four) of the plurality of pipes 30 (see FIG. 2) is shown. Moreover, in FIG.2 and FIG.3, the code | symbol of the piping 30 and its component (31-53) is attached | subjected to only one part among the some piping 30. FIG.

As shown in FIG. 1, the swivel joint 31 is a connection portion between a pipe on the upper swing body side and a pipe on the lower main body 5 side.
The in-car body pipe 33 is disposed inside the car body 10.
The elbow 35 is fixed to the side surface 10 s of the car body 10. The elbow 35 bends in the front-rear direction X from the lateral direction Y.

  The car body side port 39 is a connection port (connector) to which the hose 40 is attached. The car body side port 39 is fixed to the side surface 10 s of the car body 10. The car body side port 39 is disposed, for example, at the center in the front-rear direction X of the side surface 10s. The car body side port 39 is fixed to the front end portion (front end portion and rear end portion) of the elbow 35.

  The hose 40 connects the car body side port 39 and the crawler frame side port 51. One end of the hose 40 is fixed to the side surface 10s (car body side port 39) of the car body 10. The hose 40 and the car body side port 39 are connected even when the construction machine 1 is in a disassembled state (always connected). The other end of the hose 40 is detachable from the crawler frame 20 (crawler frame side port 51). The hose 40 and the crawler frame side port 51 are in a connected state when the construction machine 1 is in the assembled state, and in a disconnected state when the construction machine 1 is in the disassembled state. Hereinafter, the one end side of the hose 40 is also referred to as a “base end side”, and the other end side is also referred to as a “tip end side”. As shown in FIG. 2, the hose 40 includes, for example, a main body portion 41 and a coupler 43. 2 and 3, the front axle 15F is indicated by an imaginary line, and the left crawler frame 20L is not shown.

  The main body portion 41 is a portion that bends easily (bending portion, flexible portion) in the hose 40. The main body 41 is made of, for example, rubber or fiber.

  The coupler 43 allows the hose 40 and the crawler frame side port 51 (see FIG. 1) to be detachable. The coupler 43 is provided at the end portion on the front end side of the hose 40. The coupler 43 is connected to the main body 41 via a fitting (not shown). The coupler 43 is a detachable (quick coupler), for example, without using a special tool, for example, can be detachable with a screw or the like, and can be detachable with a single touch, for example.

  The crawler frame side port 51 (see FIG. 1) is a connection port (connector, coupler) to which the coupler 43 of the hose 40 is attached. As shown in FIG. 1, the crawler frame side port 51 is fixed to the surface on the inner side Y <b> 1 in the lateral direction of the crawler frame 20. The crawler frame side port 51 is disposed in the vicinity of the connecting portion between the axle 15 and the crawler frame 20 (rear of the front axle 15F, front of the rear axle 15R).

  The actuator pipe 53 connects the crawler frame side port 51 and the actuator 25.

  As shown in FIG. 3, the hose storage member 60 stores the entire hose 40 at the side of the side surface 10 s of the car body 10 (laterally outer side Y2). That is, the hose is stored so that the hose 40 does not fall off to the ground even if the hose 40 is not held at a position other than the side of the side surface 10s of the car body 10 (eg, in front of the front surface 10f or behind the rear surface 10r). The member 60 holds the hose 40. The hose storage member 60 does not need to cover the entire hose 40 and does not need to contact the entire hose 40. The hose storage member 60 is attached (fixed) to the side surface 10s (so-called storage surface). As shown in FIG. 1, the hose storage member 60 is attached to both the left and right side surfaces 10s. As shown in FIG. 3, one hose storage member 60 is connected to the entire hose 40 connected to the front crawler frame side port 51 (see FIG. 1) and the rear crawler frame side port 51 (see FIG. 1). The entire hose 40 to be connected is stored. As shown in FIG. 2, the hose storage member 60 is attached to the lower part of the side surface 10s. The hose storage member 60 includes, for example, a plate portion 61, a hook 63, and a hook 65 (see FIG. 3).

  The plate portion 61 is a plate protruding from the side surface 10s to the laterally outer side Y2. The plate portion 61 is, for example, a rectangle and extends in the front-rear direction X. The plate portion 61 is, for example, a part of the bottom plate of the car body 10 and may be a plate different from the bottom plate, for example.

  A plurality of hooks 63 (five in FIG. 2) are attached to the plate portion 61. The hook 63 protrudes upward from the plate portion 61. The plurality of hooks 63 constitute a fence. The hook 63 may be fixed to the plate portion 61 or may be detachable.

  As shown in FIG. 3, the hook 65 holds a bent portion (near the end in the front-rear direction X) of the hose 40 in the hose retracted state (described later). The hook 65 is attached (fixed) to, for example, the side surface 10 s of the car body 10.

  (Work Space S) As shown in FIG. 1, when the lower body 5 is viewed from above, the side surface 10s of the car body 10, the rear surface of the front axle 15F, the front surface of the rear axle 15R, and the lateral direction of the crawler frame 20 A portion surrounded by the surface of the inner side Y1 is referred to as “work space S”. The work space S is on each of the left and right sides of the car body 10 (only one of the two work spaces S is shown in FIG. 1). The work space S is used when the work of assembling and disassembling the lower main body 5 and the work of handling the hose 40 are performed.

(Lower body assembly procedure)
The disassembled lower main body 5 is put into an assembled state in the following order [1a] to [1d].
[1a] When the lower body 5 is in the disassembled state, as shown in FIG. 3, the hose 40 is in the “hose retracted state”. The hose storage state is a state where the hose 40 (entire) is stored in the hose storage member 60. The hose 40 in the hose retracted state is disposed inside the hook 63 (between the hook 63 and the side surface 10s). The bent portion (near the end portion in the front-rear direction X) of the hose 40 is held by the hook 65 (it may not be held). The working space S shown in FIG. 1 is secured by the hose retracted state.
[1b] The axle 15 shown in FIG. 1 is attached (assembled) to the front surface 10f and the rear surface 10r of the car body 10 with the hose stored in the state shown in FIG.
[1c] The crawler frame 20 is attached to the axle 15.
[1d] As shown in FIG. 2, the hose 40 is removed from the hose storage member 60. Then, as shown in FIG. 1, the hose 40 (coupler 43 (see FIG. 2)) is connected to the crawler frame side port 51.

(Lower body disassembly procedure)
The lower main body 5 in the assembled state is brought into a disassembled state in the following order [2a] to [2e].
[2a] The hose 40 (coupler 43 (see FIG. 2)) is removed from the crawler frame side port 51 shown in FIG. Then, as shown in FIG. 3, the hose 40 is in the hose retracted state (described above).
[2b] After the hose is stored, that is, with the work space S shown in FIG. 1 secured, the crawler frame 20 is removed from the axle 15 (divided).
[2c] The axle 15 is removed from the car body 10.

(Effect 1)
Next, effects of the construction machine 1 shown in FIG. 1 will be described. The construction machine 1 includes a car body 10 (first frame), an axle 15 (second frame) attached to the front and rear of the car body 10, and a side (horizontal) side of the car body 10 with a space from the car body 10. A crawler frame 20 (third frame) that is disposed on the outer side Y2) and attached to the axle 15. The construction machine 1 includes a hose 40 having one end fixed to the side surface 10s of the car body 10 and the other end detachable from the crawler frame 20, and a hose storage member 60.
[Configuration 1] As shown in FIG. 3, the hose storage member 60 is attached to the side surface 10s of the car body 10, and stores the entire hose 40 at the side of the side surface 10s (laterally outer side Y2).

The hose storage member 60 stores the entire hose 40 (see [Configuration 1] above). Therefore, the car body 10, the axle 15, and the crawler frame 20 shown in FIG. 1 can be assembled and disassembled while the entire hose 40 is stored in the hose storage member 60 (hose storage state). Particularly, since the position where the hose storage member 60 is attached is the side surface 10s (not the front surface 10f or the rear surface 10r) of the car body 10, the assembly and disassembly of the axle 15 with respect to the car body 10 is possible even when the hose is stored. Hereinafter, the assembly and disassembly of the car body 10, the axle 15, and the crawler frame 20 is referred to as “assembly / disassembly A”. However, “assembly / disassembly A” does not include attachment / detachment of the hose 40 to / from the crawler frame side port 51.
[Effect 1-1] Since the assembly / disassembly A can be performed with the hose stored, the assembly / disassembly A can be performed with the work space S secured. Therefore, the assembly / disassembly A can be easily performed (the efficiency of the assembly / disassembly A can be improved).
[Effect 1-2] Since the assembly / disassembly A can be performed with the hose stored, the operation of handling the hose 40 during the assembly / disassembly A (operation of removing the hose 40 from the port, hose in a place other than the hose storage member 60 There is no need to perform the operation of placing 40). Therefore, handling of the hose 40 can be facilitated.
[Effect 1-3] When the hose 40 is connected to the crawler frame 20 (to the crawler frame side port 51), the connection work can be started from the hose retracted state. Therefore, compared with the case where the connecting operation is started after the hose 40 is once arranged in a place other than the hose storage member 60 (separately), handling (handling operation, etc.) of the hose 40 can be facilitated.

  [Prior Art 1] A problem to be solved by the above "(Effect 1)" will be described. Conventionally, there is a construction machine in which the hose 40 is stored on the circumference of the car body 10 (the front surface 10f, the rear surface 10r, and the side surface 10s). However, when the hose 40 is stored in the front surface 10f or the rear surface 10r, the car body 10 and the axle 15 cannot be assembled and disassembled. Therefore, at the time of this assembly and disassembly, it is necessary to place at least a part of the hose 40 on the ground or the like. When the hose 40 is placed in the work space S, there is a problem that the work of assembly / disassembly A becomes difficult (for example, an operator needs to pay attention to his / her feet). If the hose 40 is placed outside the work space S, both ends (not only one end) of the hose 40 need to be removed from the car body 10 and the crawler frame 20. In this case, it takes time to attach and detach the hose 40 with respect to the port, a problem that it becomes difficult to handle the hose 40 by connecting the hose 40 arranged separately to the port, and [both ends of the hose from the frame] [Problem to be removed] (see the second embodiment) occurs.

(Other effects)
The “first frame” is the car body 10, and the “second frame” is the crawler frame 20. In this case, the hose storage member 60 is provided in the car body 10. Therefore, there is no problem that a cylinder (described later) provided on the crawler frame 20 becomes an obstacle when the hose 40 is taken out from the storage location. The details of this problem are as follows [Prior Art 2].

  [Prior Art 2] Conventionally, there is a construction machine in which the hose 40 is stored on the surface of the crawler frame 20 (the surface on the inner side Y1 in the lateral direction). In this conventional construction machine, the “assembly / disassembly A” is possible with the hose 40 stored. On the other hand, the crawler frame 20 is provided with a cylinder. This cylinder is for attaching and detaching a pin for connecting the axle 15 and the crawler frame 20. Depending on the arrangement of the cylinder, there is a problem that it becomes difficult to take out the hose 40 from the storage place because the cylinder becomes an obstacle.

The subframe 120 is mounted with a drive source (an engine, a hydraulic pump, etc., not shown) of the construction machine 101. For example, a control valve (a valve for controlling an actuator mounted on the upper swing body 105) is mounted on the subframe 120.

  The scaffold 129 is disposed between the main frame 110 and the subframe 120. The scaffold 129 is disposed so as to connect the upper surface (top plate 110 a) of the main frame 110 and the upper surface of the sub frame 120. The scaffold 129 is detachably attached to the scaffold attachment bracket 113 of the main frame 110. The scaffold 129 includes, for example, a pin (not shown) that can be inserted into a hole of the scaffold attachment bracket 113, a protrusion (not shown) that can be fitted into the recess of the scaffold attachment bracket 113, and the like.

  The pipe 130 is a hydraulic pipe through which oil (pressure oil, hydraulic oil) flows. The pipe 130 connects the main frame 110 and the subframe 120. The piping 130 includes, for example, for lower body traveling (forward and backward), for turning the upper turning body 105, for raising and lowering a raising and lowering member (such as a boom (not shown)) attached to the main frame 110, and the like.

The main frame side port 139 is provided, for example, at the tip of an elbow (see the elbow 35 shown in FIG. 1) fixed to the side plate 110s. In FIG. 5, only a part of the plurality of mainframe side ports 139 are denoted by reference numerals. In FIG. 5, the main frame side port 139 and the hose 140 are indicated by imaginary lines.

  As shown in FIG. 4, the hose 140 connects the main frame side port 139 and the subframe side port 151. A plurality of hoses 140 are provided. The plurality of hoses 140 are arranged at intervals. This interval is, for example, constant or indefinite (with a wide portion and a narrow portion). The lengths of the plurality of hoses 140 are, for example, constant and, for example, indefinite (some are long and some are short). One end of the hose 140 is fixed to the side plate 110s (main frame side port 139) of the main frame 110. The hose 140 and the main frame side port 139 are connected even when the construction machine 101 is disassembled (always connected). The other end of the hose 140 is detachably attached to the subframe 120 (subframe side port 151). The hose 140 and the subframe-side port 151 are connected when the construction machine 101 is in the assembled state, and are not connected when the construction machine 101 is in the disassembled state. Hereinafter, the one end side of the hose 140 is also referred to as a “base end side”, and the other end side is also referred to as a “tip end side”. As shown in FIG. 6, the hose 140 includes, for example, a main body portion 141 and a coupler 143. In FIG. 6, only a part (two at the left end in FIG. 6) of the plurality of hoses 140 is given the reference numerals of the main body 141 and the coupler 143.

  The main body 141 and the coupler 143 correspond to the main body 41 and the coupler 143 of the first embodiment shown in FIG. The coupler 143 shown in FIG. 6 makes the hose 140 and the subframe side port 151 shown in FIG. 4 detachable.

  The bracket frame 170 is a frame to which the hose holding part 180 is fixed. As shown in FIG. 5, the bracket frame 170 is attached to the main frame 110 (configured to be attachable). As shown in FIG. 6, the bracket frame 170 protrudes above the top plate 110a. As shown in FIG. 5, the bracket frame 170 protrudes upward from, for example, the laterally outer side W2 end portion of the top plate 110a. The bracket frame 170 extends in the front-rear direction V, for example. The bracket frame 170 is, for example, a combination of pipes and plates. Specifically, for example, the bracket frame 170 includes two pipes that extend in the front-rear direction V and a plate that connects the two pipes. The bracket frame 170 is configured to be split (disassembled), and is configured to be split in the front-rear direction V, for example. The bracket frame 170 is configured to be divided into a plurality of unit frames 170a, 170b, and 170c (may be divided into two or more than four). A hose holding part 180 (see FIGS. 7A and 7B) is attached to each of the unit frames 170a to 170c. The bracket frame 170 includes a frame connecting portion 171 and a bracket attaching / detaching portion 173.

  The frame connecting unit 171 connects the unit frames 170a to 170c. The frame connecting portion 171 is provided at a connecting portion in the front-rear direction V between the unit frames 170a to 170c. For example, the frame connecting portion 171 includes a hole 171a (for example, a plurality, see FIG. 7B) and a pin portion 171b (for example, a plurality of column portions of the unit frame 170b, for example) inserted into the hole 171a.

  The bracket attaching / detaching portion 173 is configured to be attachable to and detachable from the main frame 110. The bracket attaching / detaching portion 173 is configured to be attachable / detachable to / from the scaffold attachment bracket 113.

Further, for example, as shown in FIG. 5, the bracket attaching / detaching portion 173 includes a pin 173 d fitted into a hole (a hanging ring) of the hanging ring member 115 and a plate 173 e that contacts the upper end of the hanging ring member 115 (plate). Good. There may be a unit frame 170b that does not include the bracket attaching / detaching portion 173. Further, the bracket attaching / detaching portion 173 may be configured to be attachable / detachable to / from members other than the scaffold attachment bracket 113 and the suspension ring member 115, for example, attachable / detachable to / from a member dedicated to attachment of the bracket attaching / detaching portion 173 (for example, a tapped block). It may be configured. Further, instead of the bracket attaching / detaching portion 173, a bracket fixing portion (not shown) for fixing the hose holding bracket 160 to the main frame 110 (always fixing) may be provided.

  As shown in FIG. 6, the hose holding portion 180 is a member (holder) that holds (restrains) the hose 140, and a plurality of hose holding portions 180 are provided. The hose holding part 180 is attached to the bracket frame 170. As shown in FIG. 6, the hose holding portion 180 holds the distal end portion of the hose 140 or its periphery (hereinafter, “the periphery of the distal end portion of the hose 140”. The periphery of the distal end portion of the hose 140 is, for example, the distal end portion of the main body portion 141. Or the vicinity thereof, for example, the coupler 143. As shown in Fig. 8A, the hose holding portion 180 may not completely fix the periphery of the tip of the hose 140. There may be a gap between the periphery and the hose holding portion 180. The hose holding portion 180 includes, for example, a U-shaped metal fitting 181, a pin hole 183, and a pin 185. The pin hole 183 is a U-shape. The pin 185 is inserted into the two pin holes 183. The hose holding part 180 connects the hose 140 inside the U-shaped metal member 181 and the pin 185. To equity.

(Assembly state of upper swing body 105)
When the construction machine 101 shown in FIG. 4 is in the assembled state (the upper swing body 105), the upper swing body 105 is configured as follows. The subframe 120 is attached (coupled and fixed) to the main frame 110. The coupler 143 (see FIG. 6) of the hose 140 is connected to the subframe side port 151. A scaffold 129 is attached to the scaffold attachment bracket 113, and a hose holding bracket 160 (see FIG. 6) is not attached. The scaffold 129 is disposed above the hose 140.

(Disassembled state of upper swing body 105 (hose retracted state))
When the construction machine 101 (the upper swing body 105) is in the disassembled state, the upper swing body 105 is configured as follows. The sub frame 120 is removed from the main frame 110. As shown in FIG. 6, the hose holding bracket 160 is attached to the scaffold attachment bracket 113, and the scaffold 129 is not attached (the scaffold 129 is stored on the main frame 110, for example). The coupler 143 of the hose 140 is removed from the subframe side port 151 (see FIG. 4). The periphery of the tip of the hose 140 is held by the hose holding part 180 of the hose holding bracket 160.

(Effect 2)
Next, the effect of the construction machine 101 shown in FIG. 4 will be described. The construction machine 101 includes a main frame 110 (one side frame) including a top plate 110a and a side plate 110s, a sub frame 120 (another side frame) attached to the main frame 110, and one end fixed to the side plate 110s of the main frame 110. And a hose 140 whose other end is detachable from the subframe 120 and a hose holding bracket 160 attached to the main frame 110 shown in FIG.
[Configuration 2] The hose holding bracket 160 holds the hose 140 above the top plate 110a of the main frame 110.

  With the above [Configuration 2], it is possible to secure a large storage space for the hose 140 as compared with the case where the hose 140 is stored so as to be accommodated in the side plate 110s when viewed from the side. Therefore, handling (housing operation etc.) of the hose 140 can be facilitated, and many hoses 140 can be stored in the main frame 110. Moreover, since the necessity to bend the hose 140 (main body part 141) can be reduced, as a result of being able to suppress the load which arises by the bending of the hose 140, it can suppress that the hose 140 hurts.

[Prior Art 3] The problem to be solved by the “(Effect 2)” will be described. Conventionally, both ends of the hose 140 may be removed from two frames (for example, the main frame 110 and the sub frame 120 shown in FIG. 4) when the construction machine is disassembled. In this case, the following problems [a] to [d] may occur.
[Problems caused by removing both ends of the hose from the frame]
[A] In order to be able to remove both ends of the hose 140 shown in FIG. 4 from the frame, couplers 143 (see FIG. 6) are required at both ends of the hose 140. Therefore, the following problems [a1] and [a2] may occur. [A1] Compared to the case where the coupler 143 is provided only at one end of the hose 140, the hose 140 is less likely to bend (bend portion redundancy is reduced). Therefore, it becomes difficult to share a plurality of hoses 140. More specifically, the length of the main body 141 (see FIG. 6) of the hose 140 is variously set according to the distance between the frames (according to the distance between the main frame side port 139 and the subframe side port 151). The need becomes higher. [A2] Compared to the case where the coupler 143 is provided only at one end of the hose 140, the number of couplers 143 increases (doubles), so the cost of the coupler 143 increases.
[B] Since both ends of the hose 140 are attached to and detached from each frame, the number of attaching / detaching work steps is increased (doubled) as compared with the case where only one end is attached / detached.
[C] After removing both ends of the hose 140 from each frame, the following problems [c1] to [c4] may occur. [C1] The possibility of oil leakage from the hose 140 or the port increases. [C2] The storage location of the hose 140 needs to be set. [C3] The hose 140 needs to be transported to the storage location. [C4] The hose 140 may be lost.
[D] When connecting to the port of the hose 140, the possibility of incorrect connection or use of an incorrect product increases.

  [Prior Art 4] Conventionally, as shown in FIG. 10, there is a construction machine in which one end of a hose 340 is fixed to a frame and the other end of the hose 340 is detachable from the frame. In this conventional construction machine, the above [problem caused by removing both ends of the hose from the frame] does not occur, but the hose 340 is difficult to handle. More specifically, in this conventional construction machine, the hose 340 is stored in the side plate 310s (elongated space) between the top plate 310a and the bottom plate 310b. Usually, a member other than the hose 340 (for example, a pipe (not shown) connected to the hose 340) other than the hose 340 is disposed on the side plate 310s, and a hole (not shown) through which the pipe passes may be formed on the side plate 310s. Therefore, there is a possibility that a sufficient storage space for the hose 340 cannot be secured. In this conventional construction machine, the hose 340 stored in the side plate 310s is stored in a bent state. Therefore, there is a possibility that the work for bending the hose 340 may be troublesome, and the hose 340 may be damaged by bending the hose 340.

(Effect 3)
As shown in FIG. 5, the hose holding bracket 160 includes a bracket attaching / detaching portion 173 configured to be detachable from the main frame 110.

  In this configuration, the hose holding bracket 160 can be removed from the main frame 110 when the hose 140 is not required to be stored (when the construction machine 101 (see FIG. 4) is in the assembled state). As a result, it is possible to eliminate restrictions on the layout of devices (not shown) arranged on the main frame 110 (restrictions by the hose holding bracket 160). The “apparatus arranged on the main frame 110” is, for example, an actuator (such as a winch), piping, and wiring.

(Effect 4)
As shown in FIG. 4, the main frame 110 includes a scaffold attachment bracket 113 configured to be capable of attaching the scaffold 129. As shown in FIG. 5, the bracket attaching / detaching portion 173 is configured to be attachable / detachable to / from the scaffold attachment bracket 113.

  In this configuration, the scaffold mounting bracket 113 is used both for mounting the scaffold 129 (see FIG. 4) and for mounting the hose holding bracket 160. Therefore, a member provided only for attaching the hose holding bracket 160 to the main frame 110 (for example, a fixture such as a tapped block) is unnecessary. As a result, it is possible to eliminate the restriction on the layout of the devices arranged on the main frame 110 (the restriction on the layout due to the above “members dedicated for mounting”).

(Effect 5)
The hose holding bracket 160 includes a bracket frame 170 attached to the main frame 110 and a plurality of hose holding portions 180 attached to the bracket frame 170 and holding the hose 140.
[Configuration 5] The bracket frame 170 is configured to be divided into a plurality of unit frames 170a to 170c to which the hose holding portions 180 are respectively attached.

  With the above [Configuration 5], the components of the hose holding bracket 160 can be reduced in size and weight. Therefore, the transportation work of the hose holding bracket 160, the attachment work to the main frame 110, and the removal work can be easily performed.

(Modification of the second embodiment)
With reference to FIG. 9, the difference with the said 2nd Embodiment is demonstrated about the hose holding bracket 260 of the modification of 2nd Embodiment. As shown in FIG. 5, in the second embodiment, the hose holding part 180 is attached to the bracket frame 170, but as shown in FIG. 9, in this modified example, the hose holding part 180 is attached to the scaffold 229. As shown in FIG. 4, in the second embodiment, the scaffold 129 can be attached to and detached from the scaffold mounting bracket 113. However, in this modified example, the scaffold 229 can be raised and lowered on the main frame 110 as shown in FIG. Attached to. Hereinafter, the difference will be further described.

  The state of the scaffold 229 can be changed between the “scaffold use state” and the “bounce-up storage state”. The scaffold use state is a state when the scaffold 229 is used as a scaffold, and is the same state as the use state of the scaffold 129 of the second embodiment shown in FIG. As shown in FIG. 9, the scaffold 229 in the use state of the scaffold is disposed so as to protrude from the top plate 110a to the laterally outer side W2. The flip-up storage state is a state where the scaffold 229 is raised with respect to the main frame 110. The scaffold 229 in the flip-up retracted state is disposed so as to protrude upward (above the top plate 110a) from the top plate 110a. The lower surface (back surface) of the scaffold 229 when the scaffold is in use is referred to as a lower surface 229b.

  A plurality of hose holding portions 180 are attached to the lower surface 229b. The hose holding part 180 is attached to the surface of the lateral side W2 of the scaffold 229.

(Effect 6)
The effect by the modification of 2nd Embodiment shown in FIG. 9 is demonstrated. The construction machine 101 (see FIG. 4) includes a scaffold 229 attached to the main frame 110 so as to be raised and lowered. The hose holding bracket 260 includes a hose holding portion 180 that holds the hose 140 (see FIG. 6).
[Configuration 6-1] The scaffold 229 can change the state between the scaffold use state and the flip-up storage state that is a state that has occurred with respect to the main frame 110.
[Configuration 6-2] The hose holding portion 180 is attached to the lower surface 229b of the scaffold 229 when the scaffold is in use.

With the above [Configuration 6-2], the hose holder 180 does not get in the way when the scaffold is in use.
With the above [Configuration 6-1], it is not necessary to attach / detach the scaffold 229 and the hose holding bracket 260 (the hose holding portion 180) to the main frame 110. Further, there is no fear that the removed scaffold 229 and the hose holding bracket 260 may be lost, and it is not necessary to set the storage location thereof.

(Other variations)
The above-described embodiment and modifications can be further variously modified. For example, the frame to which the hose 40 (see FIG. 1) or the hose 140 (see FIG. 4) is fixed or detached is a frame that constitutes the construction machine 1 (see FIG. 1) or the construction machine 101 (see FIG. 4). It does not have to be any frame as described above (the car body 10, the crawler frame 20, the main frame 110, and the subframe 120 shown in FIG. 4).
