Description

Technical Field

[0001] The utility model belongs to the technical field of hoisting machinery devices, and particularly relates to a lifting device for a drainage vehicle. Background Art

[0002] During the coal mining process, water disasters have a great impact. Therefore, drainage vehicles with high intelligence, suitable for narrow underground roadway dimensions, and stable performance have emerged as the times require. During the assembly and test links in the production process of the drainage vehicle, hoisting is required. With ordinary lifting tools, four slings or suspension ropes are led out from the chassis and converge on the crane hook. The triangular force formed by the sling and the vehicle body makes the shell extremely easy to deform, not only causing damage to the appearance, but even possibly causing misalignment of mechanical fixing parts, affecting the product quality. Moreover, the multi-strand ropes are unevenly stressed, and it is easy to have the problem that the single-strand steel wire rope is overstressed beyond the required value, resulting in damage to the suspension rope, and there are potential safety hazards.

[0027] In order to make the purpose, content and advantages of the utility model clearer, the specific implementation methods of the utility model are further described in detail below in conjunction with the drawings and embodiments.

[0028] This embodiment provides a drainage vehicle lifting device, comprising: a pull rod 1, a limit block 2, a pin 3, a wedge block 4 and a fixing seat 5;

[0029] The pull rod 1 is configured as a cylindrical rod body, with positioning parts at the upper and lower ends, and circular positioning holes are opened in the middle of the positioning parts at both ends, and a pin shaft 3 is inserted through the positioning holes at the bottom;

[0030] The fixing seat 5 is fixed at the four corners above the chassis of the drainage vehicle, a groove is provided on one side of the top of the fixing seat 5, a sliding groove is provided on the other side of the top of the fixing seat 5 in the vertical direction, and a pin shaft hole is provided in the middle of the fixing seat 5 in a direction parallel to the chassis of the vehicle;

[0031] The other end of the pin shaft 3 is placed in the pin shaft hole of the fixing seat 5;

[0032] The limit block 2 is inserted into the groove on the fixing seat 5, and the setting direction of the limit block 2 is the same as the direction of the pull rod 1;

[0033] The wedge block 4 is slidably disposed in the sliding groove of the fixing seat 5 .

[0034] The circular positioning hole at the bottom of the pull rod 1 is interference fit with the pin 3 .

[0035] The circular positioning hole at the bottom of the pull rod 1 is welded and fixed to the pin 3 .

[0036] The opening of the groove at the top of the fixing seat 5 limits the swing direction of the limit block 2;

[0037] The limit block 2 and the pin shaft 3 are interference fit.

[0038] Among them, an annular groove is provided at one end of the pin shaft 3, and the opening of the annular groove matches the width size of the wedge block 4, which is used to lock the axial position of the pull rod 1.

[0039] The wedge block 4 is configured to slide on the fixed seat 5 and can be used to insert the pin shaft 3 when it slides to the upper end. After the pin shaft 3 is inserted, it is pushed to the lower end to lock the pull rod 1.

[0040] Wherein, the drainage vehicle lifting device includes a block 6;

[0041] The stopper 6 is welded on the fixing seat 5 to limit the sliding position of the wedge block 4 and prevent the wedge block 4 from sliding out.

[0042] The drawbar is a rigid structure connected to the sling. During the hoisting process of the drainage vehicle, the four drawbars form a three-dimensional space to protect the housing of the drainage vehicle from being squeezed and deformed by the sling and to achieve uniform stress. The limit block restricts the movement direction of the drawbar, and its swing angle range is consistent with the movement direction of the limit block, ensuring that its inward swing angle is controllable and does not swing outwards. The mating part of the pin shaft and the wedge block is an annular groove, which cooperates with the wedge block to lock the axial position of the drawbar. The wedge block can slide up and down, and its position is limited by the stop block. During use, it is lifted upwards, inserted into the pin shaft, and then moved to the lower end. One side of the fixed block is provided with a groove, which cooperates with the limit block to restrict the swing direction of the drawbar. The central hole cooperates with the pin shaft. The other side is provided with a groove near the end face, and the opening size is equivalent to the width of the wedge block. The stop block is welded at the uppermost end to limit the sliding position of the wedge block.

[0043] Hoisting process: Lift the wedge block 4 upwards to the position of the stop block 6. The connected drawbar 1, pin shaft 3, and limit block 2 are inserted into the pin holes of the fixed seat 5. The limit block 2 fits with the limit groove on the fixed seat 5. Release the hand, and the wedge block 4 slides to the lower end, and the drawbar 1 is then ready for hoisting.

[0044] During the hoisting process, the four drawbars 1 form a three-dimensional space to protect the housing of the drainage vehicle from being squeezed and deformed by the sling and to achieve uniform stress.

[0045] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and deformations can be made, and these improvements and deformations should also be regarded as the protection scope of the present invention.
