Description

[Detailed Description of the Invention] This invention relates to an improvement in the frame structure of a transport vehicle with a winch.

Conventionally, as shown in Fig. 1, this type of transport vehicle has crawler frames 2, 2' that support running crawler tracks 1, 1' at the bottom of both sides of the machine body, and the crawler frames 2, 2' are connected astride between the crawler frames 2, 2'. Several horizontal frames 3... and running crawler tracks 1 on these horizontal frames 3...
Frame structure A is constructed by connecting supporting frames 4 and 4' made of pipe material or channel material, which are erected and fixed in the longitudinal direction of the fuselage so as not to come into contact with the inner edge of the upper side of frame 1'. As a result, a plurality of intermittent spaces B... are created in the support frames 4, 4', and during driving, the traveling crawler tracks 1, 1' carry around dirt, snow, straw, grass, twigs, etc. and adhere to the support frames 4, 4'.
Problems such as abnormal wear of the wrapped tracks and a decrease in output due to this, and problems such as the support frame 4,
There were also problems such as dirt, snow, etc. adhering to the winch device 5 disposed between 4'.

Therefore, this invention solves these problems by simply changing the frame structure by forming the support frame from a plate material, thereby eliminating the intermittent spaces where soil and twigs from the running track tend to adhere.

Hereinafter, embodiments of this invention will be described based on the drawings.

Fig. 2 shows a transport vehicle with a winch that has a frame structure according to this invention, and its main parts are endless running tracks 1 and 1' at the bottom of both sides of the machine body, a frame structure A, and a loading platform installed on this frame structure A. 6,
The operating unit 7 and the loading platform 6 are installed in front of the loading platform 6.
It consists of a winch device 5 and the like arranged below.

The frame structure A includes crawler frames 2, 2' that support the traveling tracks 1, 1', several horizontal frames 3 connected across the crawler frames 2, 2', and the horizontal frames 3. Support frames 8, 8' formed of substantially inverted trapezoidal plates are connected to the upper inner edges of the traveling tracks 1, 1' so as not to come into contact with them. (See Figure 3). Therefore, due to the existence of the plate-shaped support frames 8, 8', the space created between the support frames 8, 8' can be separated from the respective upper sides of the traveling tracks 1, 1', and the space formed between the support frames 8, 8' can be separated from the upper sides of each of the traveling tracks 1, 1'. The intermittent space B created by 4 and 4' also disappears.

Since this invention has the above structure, the structure for placing and supporting the loading platform is extremely simplified compared to the conventional support frame that uses pipe materials or channel materials, and There are no multiple intermittent spaces near the top of the crawler track,
The running tracks carry around dirt, snow, straw, grass, twigs, etc., and no longer stick to or wrap around the support frame, making mud removal easier. As a result, it has become possible to prevent abnormal wear of the track discs due to foreign matter adhering to the support frame and the resulting reduction in output, unlike in the prior art.

In addition, since the winch device installed between the support frames at the bottom of the loading platform is isolated from the upper side of the running tracks by the plate-shaped support frame, mud, snow, etc. carried around by the running tracks can be removed from the winch. It also prevents the winch from being scattered or attached to the equipment and has the effect of protecting the winch equipment.
