TECHNICAL FIELD The present invention relates to a connecting device between a rotary press-fitting device and a traveling work machine that are received by the motor and a method for using the connecting device .

  As a construction method of cast-in-place piles, press the casing into the ground while rotating or swinging with a rotary press-fitting device, discharge the earth and sand in the casing, insert the reinforcing bar and tremy pipe, supply the ready-mixed concrete, A method of pulling out and recovering the casing is known.

A rotary press-fitting device is generally used as an installation type, and is moved to the next construction position by a crane while being suspended in the construction site.
A crawler-type traveling work machine, such as a mobile crane equipped with a hammag rub or a ground drill that holds and rotates a kelly bar with a drilling bucket attached to the lower end, is generally used to discharge sediment in the casing.

Japanese Utility Model Publication No. 3-52262.

  A plurality of casings are installed by a rotary press-fitting device at one construction site. When moving the rotary press-fitting device, as described above, it is generally different from a traveling work machine that excavates the earth and sand in the casing. It is based on a large crane with a large lifting capacity.

For this reason, every time the rotary press-fitting device moves, it is possible to wait for the crane, and it is necessary to detach the connecting frame, resulting in poor work efficiency. Note that it is uneconomical to use a large crane as a traveling work machine in consideration of movement. Accordingly, an object of the present invention is to provide a connecting device between a rotary press-fitting device and a traveling work machine, and a method of using the same, which enables the rotary press-fitting device to be moved while the connecting frame is connected to the traveling work machine. Yes.

In order to achieve the above object, the invention of claim 1 employs the following means. That is,
A traveling work machine used for excavation work of earth and sand in the casing is connected to a rotary press-fitting apparatus that press-fits while rotating or swinging the casing into the ground, and the rotational reaction force of the rotary press-fitting apparatus is received by the traveling work machine. In the connecting device between the rotary press-fitting device and the traveling work machine, the connecting member is fixed to one end surface of the base frame of the rotary press-fitting device, and the connecting member is fixed to the front end of the track frame of the traveling press. , One end of a connecting frame having connecting metal fittings fixed to both ends is connected to the connecting member of the base frame with a first horizontal pin, and the other end of the connecting frame is connected to the connecting member of the track frame in a second horizontal direction. connected by pins, a locking means for regulating the contact of the rotation of the fulcrum first pin of the rotary press fitting device when lifting the front end portion of the rotary press fitting apparatus provided by the traveling working machine It is characterized in that.

  At that time, in order to facilitate the connection between the connection frame and the track frame, the connection frame and the upper frame or the lifting frame of the rotary press-fitting device may be fastened by a rope member. Moreover, in order to change the space | interval of a rotary press-fit apparatus and a traveling type working machine according to a work form, the said connection frame is good also as a structure which can be expanded-contracted in a horizontal direction.

The traveling working machine may be a self-propelling type capable of excavating the earth and sand in the casing, and may be an excavating machine such as a hammer maglab or an earth drill generally used for civil engineering construction work.
The connecting frame is provided with connecting metal fittings for connecting with both the first and second pins in the horizontal direction at both ends, and the shape is arbitrary.

  The connecting member fixed to one end surface of the base frame for connecting with the first pin may be directly fixed to the base frame, or a bracket having the connecting member fixed thereto may be fixed to the base frame. . Further, the connecting member on the track frame side for connecting with the second pin may be fixed directly to the track frame, or an attaching member fixed with the connecting member may be attached to the track frame. In this case, if the attachment member is connected to the track frame with a connection pin in the vertical direction, the connection frame can be easily detached.

  In addition, the pin hole of the connecting member of the track frame through which the second pin is inserted is made much larger than the pin diameter or is a long hole in the vertical direction so that it can be connected even if the traveling work machine is tilted to the left and right with respect to the base frame. It is desirable to be able to do it.

The rotary press-fitting device is moved by traveling of the traveling work machine while the connection frame is connected to the traveling work machine.
The locking means is for moving, and when the rotary press-fitting device pivots with the front end of the rotary press-fitting device suspended and the first pin as a fulcrum, the rotary press-fitting device comes into contact with the connecting frame and is integrated. Any configuration may be used. For example, the front end of the connection fitting at one end of the connection frame is a surface that protrudes upward, and the locking member that abuts the protrusion surface when the rotary press-fitting device is suspended and rotated around the first pin as a base It is easy to provide on the frame side.

  The rotation angle is arbitrary, but it is preferable that the locking means does not act even if the base frame of the rotary press-fitting device is tilted with respect to the ground with the jacks at the four corners in order to build the casing vertically. In addition, since the construction site using the rotary press-fitting device is usually leveled, the base frame is not extremely inclined.

According to a fourth aspect of the present invention, there is provided a method for using the connecting device between the rotary press-fitting device according to any one of the first to third aspects and the traveling work machine, wherein the traveling work machine drives the reader with a kelly bar. is thereby provided to be vertically movable kelly drive, in the connected state the consolidated frame to rotate indentation device and said traveling working machine, connects the front end portion of the rotary press fitting device with lifting means of the Kelly drive pendant rope, The reader is tilted backward, the rotary press-fitting device is lifted by the elevating means , and the second pin is used as a fulcrum while the rotation about the first pin of the rotary press-fitting device is restricted by contact by the locking means. The rotary press-fitting device is moved by being rotated and suspended, and the rotary press-fitting device is moved by the traveling of the traveling working machine.

  Traveling work machines are equipped with auxiliary suspension means for suspending casings and reinforcing rods, but often do not have suspension means for suspending large rotary press-fitting devices. When running, the stability is poor and it tends to fall forward.

  The traveling work machine used in the present invention is equipped with a kerry drive that allows the leader to drive the kelly bar, and is equipped with an excavating tool such as a drilling bucket at the lower end of the kelly bar. Suspend by means.

  The lifting / lowering means of the kelly drive has a higher suspension capacity than the auxiliary suspension means, and since the suspension load is shared by the second pin, it is possible to suspend a considerably large rotary press-fitting device. Furthermore, by tilting the reader backward, stability during running can be improved.

  There are various kinds of elevating means for the kelly drive, such as a means for engaging a pinion provided in the kelly drive with a rack attached to the leader, and a means for elevating and lowering the kelly drive with a cylinder, and any of them is not particularly limited.

In the connecting device between the rotary press-fitting device and the traveling work machine according to the first aspect of the present invention, the connecting member is fixed to one end surface of the base frame of the rotary press-fitting device, and the connecting member is attached to the front end of the track frame of the traveling work machine. One end of a connecting frame having a connecting bracket fixed to both ends is connected to the connecting member of the base frame with a first horizontal pin, and the other end of the connecting frame is connected to the connecting member of the track frame in the horizontal direction. Since it is connected with the second pin and provided with a locking means for restricting the rotation about the first pin of the rotary press-fitting device as a fulcrum when the front end of the rotary press-fitting device is lifted by the traveling work machine by contact, The rotary press-fitting device can be suspended and moved by a traveling work machine, and it is not necessary to remove the connecting device every time the rotary press-fitting device is moved, so that the working efficiency can be greatly improved.

  When the connecting frame and the upper frame or the lifting frame of the rotary press-fitting device are fastened by the rope member, the rotary press-fitting device swings the connection frame around the first pin, thereby connecting the track frame by the second pin. It becomes easy. When the connecting frame can be expanded and contracted in the horizontal direction, the interval between the rotary press-fitting device and the traveling work machine can be easily changed without removing the connecting frame depending on the work mode.

  A front frame 14 connected by two parallel support links 15 and 16 is provided at the front of the upper swing body 10a. The support link 15 is connected to a cylinder 17 having one end connected to the upper swing body 10a, and the front frame 14 rotates in the vertical direction by the operation.

  The lower end of the reader 11 is connected to the front frame 14 by a pin 13, and an extendable backstay 12 connected to the front frame 14 is connected to the middle of the back surface of the reader 11.

  The reader 11 is provided with a kelly drive 18 slidably up and down, and a kelly bar 20 having a drilling bucket 21 attached to the lower end thereof is provided in engagement therewith. The kelly drive 18 is provided with a pinion that meshes with the rack 11a attached to the reader 11, and the kelly drive 18 is moved up and down by driving the pinion.

  Further, a top sheave 19 having a plurality of sheaves is attached to the upper end of the reader 11, and auxiliary suspending means 23 for suspending the kelly bar 20 and the casing 5 and the reinforcing bar rod is provided.

  Further, a suspension fitting 24 is fixed to the lower end of the kelly drive 18 so that the suspension fitting 25 fixed to the front end opposite to the connecting device 30 of the rotary press-fitting device 1 and the pendant rope can be locked. Yes.

  The traveling working machine 10 drives the kerry drive 18 while driving the leader 11 vertically and drives the pinion to lower the drilling bucket 21 to excavate the earth and sand in the casing 5. In addition, the auxiliary suspending means 23 suspends the casing 5 and the reinforcing bar rod.

  The connection device 30 is a member that restricts the rotation of the rotary press-fitting device 1, a connection frame 31 with connection metal fittings fixed at both ends, a connection member on the base frame 3 side and the track frame 10 c side for connecting the connection frame 31, and And stopping means.

  As shown in detail in FIG. 4, the connecting frame 31 includes a member 31a having an inclined portion and a horizontal member 31b which are integrally fixed, a connecting metal fitting 33 having a tip surface protruding upward at one end, and the other end. Two bifurcated connection fittings 32 are fixed to the left and right respectively.

  On the other hand, brackets 36 are fixed to the left and right of one end side of the base frame 3 of the rotary press-fitting device 1, and locking members 38 each having a bifurcated connecting member 37 and an abutment surface 38a are fixed. Yes. In addition, connecting members 34 are fixed to the left and right ends of the track frame 10c.

  The connection fitting 33 at one end of the connection frame 31 is a first pin 39 in the horizontal direction to the connection member 37 of the bracket 36, and the connection fitting 32 at the other end is a second horizontal connection to the connection member 34 of the track frame 10c. The pins 35 are connected.

  In addition, the pin hole 34a provided in the connecting member 34 through which the second pin 35 is inserted is a long hole in the vertical direction, so that the base frame 3 can be easily connected to the traveling work machine 10 even if it is inclined in the left-right direction. I can do it.

  The locking means is composed of a locking member 38 having a tip surface projecting upward from the connection fitting 33 at one end of the connection frame 31 in the above description and an abutting surface 38a fixed to the bracket 36 (FIG. 5).

  When the rotary press-fitting device 1 and the traveling work machine 10 are in a horizontal state, the tip surface projecting upward of the connection fitting 33 serving as the locking means and the contact surface 38a of the locking member 38 are at an angle θ. It is in a separated state.

  θ is set to an angle such that the distal end surface of the connection fitting 33 and the contact surface 38a of the locking member 38 do not come into contact with each other even when the traveling work machine 10 is inclined in the front-rear direction with respect to the rotary press-fitting device 1. Therefore, the base frame of the rotary press-fitting device can be freely tilted with the jacks 3a at the four corners in order to build the casing vertically.

  When connecting the connection frame 31, the connection frame 31 is suspended, the connection fitting 33 on one end side is engaged with the connection member 37, the first pin 39 is inserted, and the traveling work machine 10 is moved to the other end. The second connecting member 35 is inserted through the connecting member 32 on the side engaged with the connecting member 34.

Then, the cylinder 17 is operated to move the front frame 14 in the front-rear direction so that the drilling bucket 21 is positioned at the center of the casing 5.
Thus, since the position in the front-rear direction of the drilling bucket 21 can be changed as appropriate, the same connection frame 31 of the connection device 30 can be used even if the size of the rotary press-fitting device 1 is different.

  Since the coupling device 30 is configured in this way, the rotational reaction force when the rotary press-fitting device 1 is operated is received from the base frame 3 by friction with the ground of the traveling work machine 10 via the coupling device 30. It is done.

Next, as a second embodiment of the connecting device 30, an apparatus that facilitates connection with the traveling work machine 10 will be described with reference to FIG. 6.
The connecting frame 31 has the same configuration as described above although the length of the member 31a is slightly shorter, and the connecting state on the track frame 10c side is different.

  That is, the connecting member 41 is fixed to the front end of the track frame 10c, and the mounting member 42 to which the connecting member 34 is fixed is connected by the connecting pin 43 in the vertical direction. The connection fitting 32 at the other end of the connection frame 31 is connected by the second pin 35 as described above.

  Since it is configured in this manner, when it is desired to disconnect the connection frame 31 and the traveling work machine 10, for example, the rebar bar is located away, and the traveling work machine 10 is moved to suspend it. In such a case, the connecting pin 43 may be removed. Since the connecting pin 43 is in the vertical direction, it can be easily removed without suspending the connecting frame 31, and hole alignment at the time of connection is also easy.

Further, as a third embodiment of the connecting device 30, a device that facilitates connection with the traveling work machine 10 will be described with reference to FIG. 7.
The connection fitting 31 c is fixed to the connection frame 31, and the connection fitting 7 b is fixed to the side surface of the upper frame 7 of the rotary press-fitting device 1. After the connection frame 31 and the base frame 3 are connected by the first pin 39, both the connection fittings 31c and 7b are fastened by the rope member 40 such as a chain.

  Then, the elevating cylinder 4 of the rotary press-fitting device 1 is driven to raise the upper frame 7. As a result, the connecting frame 31 swings around the first pin 39 as a fulcrum, and the connecting bracket 32 on the track frame 10c side is lifted. The raising / lowering amount of the connecting bracket 32 and the connecting member 34 of the track frame 10 c is adjusted by the lifting cylinder 4. After the alignment, the second pin 35 is inserted.

  In this manner, the connecting frame 31 and the track frame 10c can be easily connected by swinging the connecting frame 31 around the first pin 39 using the elevating cylinder 4. The connecting bracket 7 b may be provided on the elevating frame 2 without being limited to the case where the connecting bracket 7 b is provided on the upper frame 7. Further, the present invention is not limited to the raising / lowering by the raising / lowering cylinder 4, and can be similarly implemented by driving the chuck cylinder 6 or driving the raising / lowering cylinder 4 and the chuck cylinder 6 together to raise / lower the upper frame 7.

Furthermore, as a fourth embodiment of the connecting device 30, the connection with the traveling work machine 10 will be described with reference to FIGS.
The connection frame 31 of the fourth embodiment is formed to be extendable and contraction, and the connection frame 31 includes a first frame 31d and a second frame 31e. The second frame 31e is slidably inserted into the first frame 31d and is formed to be extendable. Then, the connecting pin 55 is inserted and fixed to the first frame 31d and the second frame 31e. Further, stopper members 31f and 31g are provided on the second frame 31e, and the second frame 31e is regulated so as not to come off from the first frame 31d.

  Thereby, the length of the connection frame 31 can be adjusted, and the interval between the rotary press-fitting device 1 and the traveling work machine 10 can be easily changed without removing the connection frame 31 depending on the work mode. For example, as shown in FIG. 1, when the excavation by the drilling bucket 21 attached to the kelly bar 20 is switched to the excavation by the hammaglab 60 as shown in FIG. 10, the interval between the rotary press-fitting device 1 and the traveling work machine 10 is changed. Different.

  That is, in the case of excavation work by the hammaglab 60, the hammaglab 60 is suspended from the auxiliary suspension means 23, so that the drilling bucket 21 is removed from the kelly bar 20 and the backstay is avoided in order to avoid interference between the hammaglab 60 and the kelly bar 20 and kelly drive 18. 12 is extended and the reader 11 is tilted forward.

  Accordingly, in order to align the excavation center, it is necessary to increase the distance between the rotary press-fitting device 1 and the traveling work machine 10. If various connecting frames 31 having different lengths are prepared and replaced each time, the work takes time and is troublesome. Therefore, when switching from excavation by the drilling bucket 21 to excavation by the hammer mag 60, the connecting pin 55 is pulled out, the traveling work machine 10 is driven to slide the second frame 31e, and the length of the connecting frame 31 is rotated. Adjustment is made so that the center of the press-fitting device 1 and the excavation center of the hammaglab 60 coincide.

  Then, the connecting pin 55 is inserted to connect the first frame 31d and the second frame 31e. The main purpose of the connecting pin 55 is to ensure positioning, and therefore it is not always necessary to insert the connecting pin 55 during operation.

Next, FIG. 11 shows an embodiment of a method (invention of claim 4) for moving the rotary press-fitting device 1 to the next construction point using the connecting device between the rotary press-fitting device and the traveling work machine described above. This will be explained based on.

The rotary press-fitting device 1 is moved by traveling the traveling work machine 10 while the connection frame 31 is connected to the rotary press-fitting device 1 and the traveling work machine 10.
First, the drilling bucket 21 of the kelly bar 20 mounted on the traveling work machine 10 is removed, and one end of the pendant rope 26 is connected to the hanging bracket 24 of the kelly drive 18 and the other end is coupled to the hanging bracket 25 of the rotary press-fitting device 1. .

Then, the backstay 12 is reduced and the reader 11 is tilted backward by a predetermined amount. Although this inclination angle is arbitrary, it is inclined backward by 66 degrees in FIG.
Next, the Kelly drive 18 is raised to lift the rotary press-fitting device 1. Thus, the rotary press-fitting device 1 rotates with the first pin 39 as a fulcrum while the jack 3a on the connection frame 31 side is grounded, and the contact surface 38a of the locking member 38 contacts the front end surface of the connection fitting 33, Subsequently, the second pin 35 is pivoted together with the connection frame 31 with the second pin 35 as a fulcrum.

When the rotary press-fitting device 1 is lifted to such an extent that the rotary press-fitting device 1 does not hit the ground irregularities or obstacles, the rise of the kelly drive 18 is stopped.
The lifting load F by the pendant rope 26 when the rotary press-fitting device 1 is lifted is W × a / b. Here, W is the weight of the rotary press-fitting device 1, a is the distance from the second pin 35 to the center of gravity of the rotary press-fitting device 1, and b is the shortest distance from the second pin 35 to the pendant rope 26.

  Therefore, the lifting load (F) of the pendant rope 26 can be reduced by the amount of the second pin 35 sharing the load of W-Fcosα when the hanging angle of the pendant rope 26 is α.

  If the rotary press-fitting device 1 is not heavy, it may be lifted by the auxiliary suspension means 23 of the traveling work machine 10, or the traveling work machine 10 can be kept stable without tilting the leader 11 backward. In this case, the reader 11 may be left in a vertical state.

  In the above embodiment, the traveling work machine has been described in which the front frame 14 supporting the leader 11 can be rotated by the links 15 and 16, but the lower end of the leader is tilted rearward to the front part of the upper swing body. It may be supported as possible.

  The present invention is not limited to such embodiments as described above, and can be implemented in various modes without departing from the gist of the present invention.
