[0018] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.
[0019] Depend on Figures 1 to 5 It can be seen that a leveling equipment for concrete construction includes a traction arm 1, a connecting arm 2 is hinged at the front end of the traction arm 1, the traction arm 1 and the connecting arm 2 rotate in a vertical plane, the connecting arm 2 is connected to the traction machinery, the connecting arm 2 and the traction mechanism rotate in a horizontal plane, a first spring 3 is arranged above the traction arm 1, an adjustable sleeve 4 is arranged above the connecting arm 2, the first spring 3 extends into the sleeve 4, a mounting plate 9 is arranged above the connecting arm 2, an adjusting rod 10 is threadedly connected to the mounting plate 9, the sleeve 4 is arranged at the end of the adjusting rod 10, a rotating shaft 5 is passed through the rear end of the traction arm 1, both ends of the rotating shaft 5 are connected to the spreading plate 7 through the connecting plate 6, and a polarization motor 8 is arranged on the spreading plate 7.
[0020] When the utility model is used in a specific way,
[0021] The connecting arm 2 is connected to the traction machinery, the traction arm 1 is connected to the connecting arm 2, and the position of the sleeve 4 is adjusted according to the construction situation, so that the first spring 3 pushes the traction arm 1 and the connecting arm 2 to maintain a reasonable angle, thereby connecting the traction arm 1 to the rear end of the connecting arm 2 at a suitable inclination angle, so that the spreading plate 7 maintains relay contact with the concrete pavement, and the spreading plate 7 flattens the concrete pavement under the action of the polarization motor 8.
[0022] The spreading plate 7 and the connecting plate 6 are fixedly connected to the bottom of the rotating shaft 5. The rotating shaft 5 and the traction arm 1 can rotate relatively. During construction, the angle of the spreading plate 7 is adjusted to keep it horizontal, and the concrete road surface is vibrated and leveled.
[0023] When the concrete pavement generates an impact force on the spreading plate 7 , the impact force will act on the first spring 3 , thereby alleviating the damage to the traction arm 1 caused by the impact force.
[0024] A rotating drum 11 is provided at the rear end of the traction arm 1, and a rotating shaft 5 is rotatably arranged in the rotating drum 11. A baffle ring 12 located at both ends of the rotating drum 11 is provided on the rotating shaft 5, and a plurality of limiting holes 13 are opened on the baffle ring 12. A fixing plate 14 is provided on the traction arm 1, and C-shaped plates 15 facing the direction of the baffle ring 12 are provided on both sides of the fixing plate 14. A limiting plate 16 is provided inside the C-shaped plate 15, and a limiting rod 17 is passed through the limiting plate 16. The end of the limiting rod 17 is inserted into the limiting hole 13 to form a limiting connection between the limiting plate 16 and the baffle ring 12. The upper and lower ends of the limiting plate 16 are connected to the C-shaped plate 15 via a guide rod 18. A second spring 19 is sleeved on the guide rod 18, and a third spring 20 is sleeved on the limiting rod 17. The third spring 20 pushes the limiting rod 17 toward the direction close to the baffle ring 12.
[0025] The relative position of the spreading plate 7 is adjusted by the relative rotation of the rotating shaft 5 and the rotating drum 11. During the adjustment, the limit rod 17 is pulled out from the limit hole 13 to make the rotating shaft 5 and the rotating drum 11 rotate relative to each other. When it rotates to a suitable angle, the limit rod 17 is released, and the third spring 20 pushes the limit rod 17 so that its end is inserted into the limit hole 13. The limit rod 17 remains connected to the rotating shaft 5. The feedback generated by the spreading plate 7 acts on the limit rod 17, and the limit rod 17 drives the limit plate 16 to fluctuate and move telescopically on the guide rod 18. The second spring 19 balances the limit plate 16 on both sides of the limit plate 16 to buffer the rigid impact and play the first layer of buffering effect on the rigid impact. When the force on the second spring 19 reaches the limit, the angle of the traction arm 1 changes, generating a force on the first spring 3. The first spring 3 and the second spring 19 cooperate with each other to reduce the damage caused by the rigid impact, protect the equipment, and enable the equipment to run smoothly.
[0026] Compared with the prior art, the utility model has the following beneficial effects: through multiple buffer mechanisms, the damage to the traction arm caused by rigid impact is reduced, the equipment is protected intact, and thus the smooth progress of the construction is ensured.
