Problems solved by technology

[0002] In order to speed up the construction progress of the bridge, a jacking machine is used to push and move the buildings of the bridge, which is beneficial to the splicing of the bridge. The jacking machine drives the track to rotate through the rotating shaft of the jacking device motor, and the track drives the bridge building forward. In addition, the jacking device and the hydraulic cylinder cooperate to lift up and down, and can adjust the height of the spliced ​​buildings; in the prior art, when the jacking machine is used to push the bridge building up, it is beneficial for the bottom surface of the bridge building to rub against the track, causing the bottom surface of the building to The material is detached, and the vibration force is generated when the track rotates, so that the material falls to both sides along the surface of the track, and the material falls down to between the rotating shaft of the motor and the mating position of the track, resulting in friction between the rotating shaft and the track The increase of the coefficient will accelerate the wear of the rotating shaft, resulting in a decrease in the degree of cooperation between the rotating shaft and the crawler belt, which will affect the normal pushing of the bridge building by the jacking machine

Embodiment 1

[0027] as attached figure 1 to attach Figure 5 Shown:

[0028] The present invention provides a modular walking multi-point pushing equipment for bridge pushing. Its structure includes a bracket 1, a support plate 2, a hydraulic cylinder 3, and a pushing device 4. The support plate 2 is horizontally fixed on the top of the support 1. , the hydraulic cylinder 3 is installed vertically at the center of the bottom of the support plate 2 , and the pushing device 4 is arranged on the top of the support plate 2 and cooperates with the hydraulic cylinder 3 movably.

[0029] The pushing device 4 is provided with a matching plate 41, a motor 42, a crawler belt 43, a rotating shaft 44, and a clearing mechanism 45. The matching plate 41 is located above the pushing device 4, and the motor 42 is installed at the front center of the matching plate 41. , the rotating shaft 44 is movably matched with the middle and lower positions of the front of the motor 42 , the crawler belt 43 surroun...

Embodiment 2

[0036] as attached Figure 6 to attach Figure 8 Shown:

[0037] Wherein, the opening s2 is provided with a supporting rod e1, an connecting shaft e2, and a diffusion ring e3, the supporting rod e1 is horizontally fixed on the inner wall of the bottom end of the opening s2, and the diffusion ring e3 is connected and installed in the center of the supporting rod e1 through the connecting shaft e2 position, the support rod e1 is in the shape of a flat plate, which is just set on the inner wall of the opening s2, which is beneficial to block the material and reduce the back suction force of the material from the airflow to enter along the opening s2, which is conducive to keeping the opening s2 unblocked and speeding up the airflow along the opening s2 The speed of diffusion.

[0038] Wherein, the diffusion ring e3 is provided with a drainage port r1, a push rod r2, and a clip r3, the drainage port r1 runs through between the outer wall and the interior of the diffusion ring e3...

Abstract

The invention discloses module walking type multi-point pushing equipment for bridge pushing, which structurally comprises a bracket, a supporting plate, a hydraulic cylinder and a jacking device, wherein the supporting plate is horizontally fixed at the top of the bracket, the hydraulic cylinder is vertically mounted at the center position of the bottom of the supporting plate, and due to the fact that materials fall down between the matching positions of a rotating shaft of a motor and a crawler belt, a rotating ring in the clearing mechanism makes contact with the inner surface of the crawler belt, a clearing block clears away materials accumulated on the inner surface of the crawler belt, the materials are blown to be separated from the inner surface of the crawler belt through airflow, the friction coefficient between a rotating shaft and the crawler belt can be reduced, the matching degree of the rotating shaft and the crawler belt is improved, and the jacking machine can normally jack a bridge building; and after the bottom plate is reset, the airflow in the air cavity generates suction force, and the diffusion ring is arranged in the opening, so that the material is blocked, the suction force of the airflow on the material entering the opening is reduced, the opening can be kept unblocked, and the airflow is accelerated to be discharged along the opening.
