Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a side frame of a transport vehicle that can be easily attached and detached.

[Conventional technology]

As shown in FIG. 6, the bed side frames of this type of conventional transport vehicle include a front side frame 9', a rear side frame 10', a left side frame 11', and a right side frame 12' surrounding the base plate 8'. was being formed. The front frame 9', the left frame 11', and the right frame 12' have support rods 15' fixed to the side frames 9', 11', and 12' connected to support pipes 16' provided on the base plate 8'. The rear frame 10' was fixed to the base plate 8'.

[Problem that the invention attempts to solve]

However, with the loading side frame of the conventional transport vehicle mentioned above,
When loading and unloading cargo, unnecessary effort is required to lift the cargo to a position above the platform side frame located above the base plate 8'. Also, if you want to remove the support rod 15' from the support pipe 16' and load/unload cargo at the same height as the base plate 8' in order to save this labor, the fixation of the fixture 18' will be released. Therefore, it is necessary to remove all or any one of the side plates 9', 10', and 11'.

[Means for solving problems]

In view of the above-mentioned circumstances, this idea was developed to allow the loading and unloading of cargo at the same height as the bed plate by easily attaching and detaching the side frames of the loading platform. The loading side frame of the transport vehicle, which is provided so as to surround the base plate, has a connecting rod holder installed at the tip of a guide rod that is formed to be expandable and contractible in the longitudinal direction of the left and right side frames, and a connecting rod holder that connects the connecting rod holder. The connecting rod consists of a hollow guide pipe, a sliding rod slidably inserted into one end of the guide pipe, and a connecting rod installed between the hollow guide pipe and the other end of the guide pipe. an adjustment rod that is removably inserted into the guide pipe; a stopper is provided at one end of the guide pipe to prevent the inserted end of the sliding rod from being pulled out; A fixture is provided on the side for fixing the fitted adjustment rod, and the sliding rod is provided with a
A spring biased in the direction of coming out of the guide pipe is fitted onto the outside, and the connecting rod is removably installed between the connecting rod holders, thereby forming the front frame or the front and rear frames. be.

[Effect]

According to the above means, the adjustment rod is adjusted and fixed at the required length position, and the left and right frames are moved while the sliding rod is moved into the guide pipe by applying an external force in a direction that resists the biasing force of the compression spring. If the external force is removed and the connection is made at the position of the connecting rod holder, the base plate can be surrounded by the side frame. On the other hand, if the sliding rod of the connected connecting rod is moved into the guide pipe by applying an external force against the biasing force of the compression spring and removed from the connecting rod holders on the left and right frames, it will be at the same height as the base plate. You can load and unload your luggage at this location.

〔Example〕

An embodiment of this invention will be described based on FIGS. 1 to 4.

As shown in FIG. 1, a transport vehicle 1 according to an embodiment of this invention is composed of a running section 2, a drive operation section 3, and a loading platform 4.

The traveling section 2 rotates the crawler 5 using the power of the drive operation section 3 to travel. The drive operation section 3 is composed of a drive source 6 and an operation device 7, and is installed at the upper rear of the traveling section 2. The loading platform 4 is installed above the traveling section 2 and in front of the drive operation section 3.

The carrier side frame of the carrier according to the embodiment of this invention has the first
As shown in the figures to FIG. 3, the front frame 9, the rear frame 1
0, it is formed by a left side frame 11 and a right side frame 12, and is expandable in the front, left, and right directions, so that the width of the loading platform 4 can be changed. Left, right frame 11,1
2, guide rods 14 are telescopically attached to both ends of the guide pipe 13, and an L-shaped support rod 15 fixed to the lower part of the guide pipe 13 is provided on the base plate 8 so that the left and right sides are in the longitudinal direction. The support pipe 16 is detachably attached to the supporting pipe 16. Further, the guide rod 14 is connected to the guide pipe 13.
A connecting rod holder 17 is provided at the end opposite to the side to be inserted into the
The connecting rod receiver 17 is provided with a through hole 17a, as shown in FIG.
Further, the guide rod 14 and the support rod 15 can be fixed to the guide pipe 13 and the support pipe 16 using a fixture 18. Front and rear frames 9, 1
0 is the small diameter portion 19 at the tip of the connecting rod 19 shown in FIG.
a is inserted into the through hole 17a of a pair of connecting rod receivers 17 provided in the guide rods 14 of the left and right side frames 11 and 12, thereby being constructed and formed. The connecting rod 19 is composed of a guide pipe 20, a sliding rod 21 which is partially slidably inserted into one end of the guide pipe 20, and an adjustment rod 22 which is removably attached to the other end. ing. The sliding rod 21
is prevented from being pulled out by a stop ring 23 provided at one end of the guide pipe 20. Further, two spring receivers 24 are fitted onto the portion of the sliding rod 21 that protrudes outward from the guide pipe 20, and the ends are clamped by the two spring receivers 24, and the outer periphery of the sliding rod 21 is A compression coil spring 25 is provided which is fitted onto the outside. One of the two spring receivers 24 is in contact with the stop ring 23 or the end surface of the guide pipe 20, and the other one is provided at the end opposite to the side where the sliding rod 21 is inserted into the guide pipe 20. It is in contact with the folded collar 26. In addition, the adjustment rod 22 can be adjusted to the fixing tool 2 at any position.
7, it can be fixed to the guide pipe 20.

According to the above-mentioned loading platform side frame, when loading cargo, the sliding rod 21 of the connecting rod 19 is connected to the compression coil spring 2.
By applying an external force that resists the urging force of 5, the small diameter portion 19 of the connecting rod 19 is moved into the guide pipe 20.
a from the through hole 17a of the connecting rod holder 17. Next, the fixing devices 18 of the left and right side frames 11 and 12 are released, and the guide rod 14 and support rod 15 are expanded to match the size of the cargo, and then the guide rod 14 and support rod 15 are expanded.
is fixed with a fixture 18 and the cargo is loaded. Then, the adjusting rods 22 of the front and rear frames 11 and 12 are adjusted by tightening and loosening the fixtures 27, and the sliding rod 21 is moved by applying an external force that resists the biasing force of the compression coil spring 25. Turn the tip small diameter part 19a to the left,
Connecting rod receiver 17 for guide rod 14 of right frame 11, 12
Then insert the connecting rod 1 into the through hole 17a of the receiver 17 again.
9, it is possible to load the cargo onto the platform 4 of the transport vehicle 1 without lifting it more than necessary. Also, when unloading cargo, if the sliding rod 21 of the connecting rod 19 is moved into the guide pipe 20 by applying an external force in a direction against the biasing force of the compression coil spring 25, the small diameter portion at the tip of the connecting rod 19 can be moved. 19a to connecting rod holder 1
It can be easily removed from the base plate 7 and the cargo can be lowered at the same height as the base plate 8.

[Effect of idea]

As is clear from the above explanation, if the sliding rod is inserted into the guide pipe with a force that resists the biasing force of the compression spring, the side frame will easily come off, allowing loading and unloading of cargo, etc. Since loading and unloading can be done at the same height as the base plate, it requires less effort than loading and unloading cargo, etc., which goes over the side frame.
