In this embodiment, the placing frame 130 is provided to have a special placing space for the sleepers 300, and the placing space is sufficient due to the large number and size of the sleepers 300. This requires a space for large tools and stock wear parts. The movable placing rack 130 is used for storing articles and can be used as a weight box, the weight box is folded and not interfered by other parts, the articles are conveniently taken and placed after being unfolded, and the center of gravity of the whole vehicle can be further stabilized.

The rack 130 and the tool box 140 are integrated into a whole, two side doors capable of being opened downwards are arranged on two sides of the rack 130, and the front of the tool box 140 is also provided with a door capable of being opened downwards so as to take articles.

The upper and lower parallel of slide rail device 150 is installed at the inboard of landing leg device 100, has three first slider 1542 on first guide rail 1522, and first slider 1542 passes through the bolt with rack and slider fixed connection, realizes horizontal support.

The driving hydraulic motor is connected with the screw rod 164, the driving hydraulic motor is fixedly installed on the inner side of the supporting leg device 100, the screw rod 164 can be parallel to the first guide rail 1522 and the second guide rail 1524, the nut 166 is a screw nut, the screw nut is fixedly connected with the placing frame 130 through a bolt, the hydraulic motor drives the screw rod 164 to rotate, the screw nut is pushed to move back and forth, and therefore the placing frame 130 is driven to move integrally.

In the non-operating state, the leg assembly 100 is collapsed, and the rack 130 and the tool box 140 are both closed and remain in a position where they do not interfere with other components of the pump truck.

In the working state, the leg device 100 is unfolded, and the rack 130 and the tool box 140 are selected to be in the opening or closing state according to the working requirement. When the sleeper 300 is needed, the front side cover plate and the rear side cover plate of the placing frame 130 are only needed to be opened, the sleeper 300 is pushed out in a mode of directly pushing from one end to the other end, and then the sleeper is taken out and placed below the supporting leg device 100. After use, the sleeper 300 is pushed into the placing frame 130 in a straight pushing mode. Because the rack 130 is placed inside the leg device 100, the crosstie 300 can be carried the shortest distance as the leg device 100 is unfolded, reducing the amount of labor of the personnel.

The tool box 140 is arranged above the placing frame 130, and the side cover plate can be completely opened, so that tools and accessories can be conveniently placed and taken.

According to the working requirement, the placing frame 130 can be driven by the hydraulic motor to move back and forth relative to the position of the supporting leg device 100, so that the effect of a weight box is achieved, and the working stability of the whole vehicle is enhanced.

To sum up, according to the utility model discloses a beneficial effect of embodiment does:

1. by arranging the placing frame 130 on the main supporting leg 120, the placing frame 130 can place the sleeper 300, and the sleeper 300 can be carried at the shortest distance along with the expansion of the main supporting leg 120 because the main supporting leg 120 is positioned on the inner side of the supporting part 110, thereby reducing the workload of operators.

2. The first side door 134 is disposed at a position close to the support part 110, further shortening the distance to carry the crosstie 300.

3. The first side door 134 and the second side door 136 are arranged opposite to each other and can be opened, so that the sleeper 300 can be placed and taken out in a direct-pushing mode, and the labor amount of an operator is reduced to the maximum extent.

4. The tool box 140 is arranged on the placing frame 130, so that the problem that large tools and routine wearing parts are placed in no space is solved, and the tool box 140 is integrated with the placing frame 130, so that no extra space is occupied.

5. The placing frame 130 is movable so that the placing frame 130 functions as a weight box and can be folded without interfering with other components, thereby further stabilizing the center of gravity.
