[Detailed description of the invention] [Field of industrial application] This invention allows the upper and lower receiving frames of the front frame to be moved individually, and also eliminates the gap between the front frame, the left side frame, and the right side frame. Concerning the loading platform of a transport vehicle that does not cause

[Conventional technology]

As shown in FIG. 4, the loading platform 2' of this type of conventional transport vehicle 1 is provided at the upper front side of the running section 4 on which the crawler 3 runs, and at the upper rear side of the running section 4. The traveling section 4 is operated by a drive operation section 5 to transport the luggage A to the destination. This loading platform 2' consists of a base plate 6 fixed to the upper part of the running section 4 and a rear frame 7 fixed to the rear end of this base plate 6.
It is composed of a left side frame 8' and a right side frame 9', which are provided on the left and right sides of the base plate 6 so as to be able to come close to and separate from it, and a front frame 10 that is provided on the front end of this base plate 6 so that it can come close to and leave it. has been done. The left side frame 8' and the right side frame 9' are fixed at right angles to the other side of a horizontal guide rod 14, one of which is inserted into a horizontal guide 13 provided at the front and back of the lower part of the base plate 6. If the lateral guide rod 14 is moved within the lateral guide rod 13, it will move toward and away from the side surface of the base plate 6 in parallel. The front frame 10' is also fixed at right angles to the other of vertical guide rods 22, one of which is inserted into the vertical guides 21 provided on the left and right sides of the lower part of the base plate 6. When the guide rod 22 is moved, it approaches and separates from the side edge of the base plate 6 in parallel. In such a loading platform 2', a large load A can be transported within the movable range of the left side frame 8', right side frame 9', and front frame 10'.

[Problem that the invention attempts to solve]

However, according to the loading platform 2' of the transport vehicle 1 mentioned above,
Movable left side frame 8', right side frame 9' and front frame 10'
When the front frame 10' is separated from the base plate 7, a gap is formed between the front frame 10' and the left and right side frames 8' and 9'. Therefore, when cargo A is loaded and transported on this loading platform 2', this cargo A is divided into the front frame 10', the left frame 8', and the right frame 9'.
There is a problem that due to the gap formed between the transport vehicle 1 and the transport vehicle 1, the transport vehicle 1 may lose its balance and fall down due to the load being dislocated or the like.

[Means for solving problems]

In view of the above circumstances, this invention is designed to prevent gaps from being created between the front frame and the left and right frames even if the movable frames are separated from the base plate. The respective ends of two receiving frames formed into a U-shape by slidably fitting a receiving guide and a receiving guide rod into each other are opened at the front end sides of the left side frame and the right side frame, respectively. and the lower opening, respectively, to form a front frame.

[Effect]

According to the above means, when the left and right side frames are moved toward and away from the base plate, the fitting portions of the receiving guide and the receiving guide rod of the receiving frame are slid and adjusted, and when the front frame is moved toward and away from the base plate, the fitting portions of the receiving guide and the receiving guide rod are adjusted. The adjustment can be made by sliding the receiving guides and receiving guide rods of the upper and lower receiving frames inserted into the left side frame and the right side frame. At this time, the upper and lower receiving frames of the front frame are fitted into the upper and lower openings of the left and right frames, so there is no space between the front frame and the left and right frames to prevent the load from collapsing. Since there are no gaps that could cause the load to collapse or shift, it does not occur. In addition, since the distance between the upper and lower receiving frames in contact with and away from the base plate can be adjusted individually, it is possible to prevent the load from collapsing due to the shape of the load.

〔Example〕

An embodiment of this invention will be described below with reference to FIGS. 1 to 3.

Note that the same reference numerals are given to the same components as those in the prior art, and the explanation thereof will be omitted.

The loading platform 2 of the transport vehicle 1 according to the embodiment of this invention has a first
As shown in FIGS. 3 to 3, a drive operation section 5 provided at the upper front side of the traveling section 4 that runs on the crawler 3 and at the rear side operates the traveling section 4 to load the cargo onto the platform 2. It is designed to transport cargo A placed there. This loading platform 2 can be freely moved toward and away from a base plate 6 fixed to the upper part of the running section 4, a rear frame 7 fixed to the rear end of this base plate 6, and both left and right ends of this base plate 6. It is comprised of a left side frame 8 and a right side frame 9 provided, and a front frame 10 provided at the front end of this base plate 6 so as to be able to approach and separate. The left side frame 8 and right side frame 9 are
Upper opening 11 and lower opening 12 opened on the front end side
A lateral guide that is made of a pipe material bent into a U-shape having one side inserted into the lateral guides 13 provided at the front and rear of the lower part of the base plate 6 and moves parallel to the base plate 6. It is fixed at right angles to the other side of the rod 14 and the pipe material on the lower opening 12 side, so that it can come into contact with and separate from the base plate 6.

The front frame 10 is composed of two receiving frames 17 formed into a U-shape by slidingly inserting an L-shaped receiving guide rod 16 into an L-shaped receiving guide 15. The end portion of the receiving frame 17 is slidably inserted into and supported by the upper opening 11 and lower opening 12 of the left side frame 8 and right side frame 9, respectively. still,
To fix the horizontal guide 13 and the horizontal guide bar 14, the receiving guide 15 and the receiving guide bar 16, and the upper and lower openings 11 and 12 and the receiving guide 15 or the receiving guide bar 16, for example, the horizontal guide 13, the receiving guide 15, and A nut 18 is attached to the upper and lower openings 11 and 12, and a thumbscrew 19 is screwed into the nut 18, and the horizontal guide rod 14, receiving guide 15, or receiving guide rod inserted at the tip of the thumbscrew 19 is inserted into the nut 18. 16 will be held.

According to the loading platform 2 of the transport vehicle 1 described above, in order to move the left side frame 8 and the right side frame 9 toward and away from the base plate 7, the receiving guide is inserted into the receiving guide 15 of the receiving frame 17 constituting the front frame 10. While moving the rod 16,
This can be done by moving the horizontal guide rods 14 inserted into the horizontal guides 13 of the left side frame 8 and right side frame 9. Further, the front frame 10 can be moved toward and away from the base plate 6 by moving the receiving frames 17 inserted into the left side frame 8 and the right side frame 9. At this time, the left frame 8 and the right frame 9 are always connected by the receiving frame 17, so the left frame 8 and the right frame 9 and the front frame 1
There is no gap between 0's. Furthermore, if the shape of the cargo A to be loaded is not vertical on the front frame 10 side as shown in FIGS. 2 and 3, the upper and lower receiving frames 17 of the front frame 10 may be adjusted individually. hand,
Since the lower receiving frame 17 of the front frame 10 supports the bottom surface of the cargo A, and the upper receiving frame 17 of the front frame 10 can press the front surface of the cargo A, it is possible to prevent the cargo A from collapsing.

Note that the left side frame 8 and the right side frame 9 are not limited to being formed by connecting the sides opposite to the upper opening 11 and the lower opening 12 with curved pipes, but may be connected with straight pipes. .

[Effect of idea]

As is clear from the above explanation, the U-shaped upper and lower support frames, which can be moved individually along the base plate, are connected to the left and right frames. There is no gap between the front frame, which is made up of receiving frames, and the load will not jump out from the gap and fall, or the load will not collapse. In addition, the upper support frame can hold the front of the load and the lower support frame can support the bottom of the load, making it possible to transport the load in a stable manner according to the shape of the front side of the load.
