Abstract

(57) [Summary] [Purpose] Use a common frame for a carrier regardless of the presence of a crane device. [Structure] An extension frame that can be inserted and fixed from the rear of the frame is provided.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a frame structure of a carrier.

[0002]

[Prior Art]

 Carriers range from simple structures that have only a fixed carrier to complex structures that have a dump carrier, crane device, etc., depending on the required specifications, in addition to the presence or absence of components, chassis and carrier. The structure is also different.

[0003]

[Problems to be solved by the device]

 In this case, it is necessary to prepare parts and the like for each specification, and the sharing of components and the like does not proceed, resulting in poor manufacturing efficiency. This invention solves such a problem, and the point is that the members can be shared even if the specifications are different.

[0004]

[Means for Solving the Problems]

 Under the above problems, the present invention provides a frame structure of a carrier having a mounting hole for receiving a support shaft for supporting a luggage carrier at a rear portion of the frame, and the mounting hole is formed at a rear portion of the frame structure from the rear of the frame. The feature is that an extension frame that can be inserted and fixed is detachably provided.

[0005]

[Action]

 When the extension frame is attached by taking the above means, the loading platform itself can be displaced rearward to make a space between the extension and the control section, so that the crane device or the like can be installed here. Therefore, the frame structure and the like can be unchanged regardless of the presence or absence of a crane device or the like.

[0006]

EXAMPLE FIG. 3 is a side view of a carrier. In this carrier, a frame 10 is supported by a crawler type traveling device 12, and a control section 14 is provided at the upper front portion of the frame 10 and a luggage carrier 16 is provided at the rear portion. It is equipped. The loading platform 16 is configured as a dump loading platform that moves up and down by a hydraulic cylinder 18 provided between the loading system 16 and the traveling device 12. For this reason, a mounting hole 20 is formed in the bracket portion 19 formed in the rear portion of the frame 10, and the luggage carrier 16 is supported through the supporting shaft 22 in the mounting hole 20.

The present invention is such that the extension frame 24 can be added to the frame 10 as described above. Although FIG. 1 is a side view showing this and FIG. 2 is a partial cross-sectional plan view, the extension frame 24 can be inserted and fixed from the rear of the frame 10. The structure for fixing is such that when the extension frame 24 is inserted into the frame 10, a bolt insertion hole 26 is formed in advance at a position located in the attachment hole 20, and the bolt 28 is inserted into the bolt insertion hole 26 and the attachment hole 20. Fix through. The width of the bracket portion 19 is slightly narrower than that of the frame 10, and when the extension frame 24 is inserted into the frame 10, there are gaps on both sides of the bracket portion 19, so that the bracket portion 19 is located inside the bolt insertion hole 26. The boss 27 is provided so that this gap is closed.

Further, since a reinforcing stay 34 is usually provided between the frame 10 and the vertical member 32 connecting the frame 10 and the track frame 30, the reinforcing stay 34 and the extension frame are provided. Bolt insertion holes 36 and 38 are also formed at positions corresponding to 24, and bolts 40 are also passed through the bolt insertion holes 36 and 38, respectively. According to such a three-point fixing structure, it can be firmly fixed and slack does not easily occur. A bracket portion 25 is also provided at the rear portion of the extension frame 24, and a mounting hole 20 for allowing the support shaft 22 to pass through is formed in the bracket portion 25.

FIG. 4 is also a side view of the carrier, but if the extension frame 24 is added to the rear of the frame 10 and the carrier 16 is displaced rearward as described above, the control unit 14 and the carrier 16 are separated. Since there is a space between them, the crane device 42 can be installed here. When the loading platform 16 is displaced rearward, the loading platform side pivot portion 44 of the hydraulic cylinder 18 provided at the bottom of the loading platform 16 naturally moves rearward, so that the traveling device side pivot portion 46 of the hydraulic cylinder 18 is moved. The position is shifted rearward by that amount, or an adapter 48 or the like is interposed to respond (in this case, the original pivot portion 46 can be used).

By the way, when the extension frame 24 is attached and the loading platform 16 is displaced rearward as described above, there is a space between the control unit 14 and the space, but it is not always necessary to install the crane device 44 or the like here. However, the cargo bed 16 may be extended to this portion, and the cargo bed 16 does not necessarily have to be the dump bed, but may be a normal fixed cargo bed.

[0011]

[Effect of the device]

 As described above, since the present invention is the one described above, it is possible to change the ordinary cargo bed specification to the crane specification without changing the frame structure. This modification can be done by a simple operation that removes the support shaft of the loading platform and attaches the extension frame, so it can be easily done even at the shop side without a modification facility.
