[0001] The utility model relates to the technical field of transportation of prefabricated bridge piers, in particular to a stable base for transportation of prefabricated bridge piers. Background Art

[0002] During the construction of bridges, in order to support the bridge surface, it is often necessary to set up a large number of piers as the lower load-bearing objects. The piers are mainly composed of reinforced concrete. With the development of the construction industry, in order to improve construction efficiency and ensure the quality and safety of construction, standard-sized bridge piers will be produced in processing plants, that is, the bridge piers will be prefabricated, and then the prepared bridge piers will be transported to the construction site and hoisted, which can greatly improve the construction progress of the bridge. However, since the prefabricated piers are large in size and weight, special transportation equipment is required for transportation. In order to ensure that the piers remain stable during transportation, the piers will be limited and fixed to ensure that the prefabricated bridge piers will not be offset due to the shaking of the transportation equipment during transportation.

[0003] The existing fixing mechanism of prefabricated bridge piers clamps and fixes the prefabricated bridge piers horizontally from the side of the pier, which causes the clamping plate of the clamping mechanism to be subjected to very large forces at a point perpendicular to the base plate, making it prone to breakage. Therefore, a stable base for transporting prefabricated bridge piers is proposed. Utility Model Content

A threaded rod is fixed on the pulling mechanism, a limiting hole is provided on the rotating mechanism, the threaded rod passes through the limiting hole, and the bottom end of the threaded rod is threadedly connected with a locking mechanism located below the rotating mechanism.

[0005] Furthermore, hinge blocks are provided at the front and rear ends of the upper surface of the base plate, and hinge holes are provided in the middle of the hinge blocks. The front and rear surfaces of the outer end of the clamping plate are integrally formed with hinge shafts, and the hinge shafts are rotatably connected to the hinge holes.

[0010] When fixing the prefabricated bridge pier, the prefabricated bridge pier is placed on at least two base plates, which are respectively located at both ends of the prefabricated bridge pier.

Both ends of the base plate 1 are provided with rotation holes 104, and the rotating mechanism 4 is rotatably connected in the rotating holes 104 of the base plate 1. A threaded rod 303 is fixed on the pulling mechanism 3, a limiting hole 402 is provided on the rotating mechanism 4, the threaded rod 303 passes through the limiting hole 402, and the bottom end of the threaded rod 303 is threadedly connected with the locking mechanism 5 located below the rotating mechanism 4.

[0025] In a specific implementation, when fixing the prefabricated bridge pier, the prefabricated bridge pier is placed on at least two base plates 1, which are respectively located at both ends of the prefabricated bridge pier. By rotating the locking mechanism 5, the locking mechanism 5 pulls the threaded rod 303 downward, so that the clamping plate 2 is pulled to move the top of the clamping plate 2 closer to the outer wall of the prefabricated bridge pier under the action of tension, and the outer wall of the prefabricated bridge pier is clamped and fixed. The operation is simple and convenient for clamping and fixing the prefabricated bridge pier.

[0026] By setting the rotating mechanism 4 , when the locking mechanism 5 pulls the threaded rod 303 to move downward, the threaded rod 303 can adapt to the rotation angle of the clamping plate 2 .

[0027] For further reference, Figure 3 、 Figure 4 and Figure 5 , hinge blocks 101 are provided at both ends of the upper surface of the base plate 1, and hinge holes 102 are provided in the middle of the hinge blocks 101. The front and rear surfaces of the outer end of the clamping plate 2 are integrally formed with hinge shafts 201, and the hinge shafts 201 are rotatably connected to the hinge holes 102;

[0028] During specific implementation, when the top of the clamping plate 2 is clamped toward the prefabricated bridge pier, the hinge shaft 201 of the clamping plate 2 rotates inside the hinge hole 102, so that the clamping plate 2 can be clamped close to the outer wall of the prefabricated bridge pier.

[0029] For further reference, Figure 7 , the inner wall of the through groove 103 is provided with a rotation hole 104 that passes through the front and rear of the substrate 1, the rotation mechanism 4 includes a rotation block 401, and two limiting rods 403 are integrally formed at both ends of the rotation block 401, and the limiting rods 403 are rotatably connected to the rotation hole 104;

[0030] In a specific implementation, when the rotating mechanism 4 is self-adapting in angle, the limiting rod 403 of the rotating block 401 rotates inside the rotating hole 104 , thereby self-adapting the angle of the threaded rod 303 when the clamping plate 2 rotates.

[0031] For further reference, Figure 6 The interior of the pulling groove 202 is provided with a rotating shaft 203 connecting the front and rear inner walls. The pulling mechanism 3 includes a pulling block 301. The front and rear sides of the pulling block 301 are provided with a through pulling hole 302. The pulling hole 302 is rotatably connected to the rotating shaft 203.

[0032] In a specific implementation, the pulling groove 202 , the rotating shaft 203 and the pulling hole 302 are arranged so that the pulling block 301 can rotate inside the pulling groove 202 .

[0033] For further reference, Figure 4 The lower surface of the tension block 301 is integrally connected with a threaded rod 303, the upper surface of the rotating block 401 is provided with a limiting hole 402 passing through the lower surface, and the threaded rod 303 crosses the limiting hole 402;

[0034] In a specific implementation, the threaded rod 303 passes through the limiting hole 402 so that the threaded rod 303 is always perpendicular to the rotating block 401, so that the locking mechanism 5 can better generate the force to pull the threaded rod 303 downward.

[0035] For further reference, Figure 8The locking mechanism 5 includes a nut 501 threadedly connected to the threaded rod 303, the nut 501 is a regular hexagonal nut, and a control rod 502 is vertically provided in the middle of the outer surface of the nut 501;

[0036] In a specific implementation, when the locking mechanism 5 is pulled, the control rod 502 is held by hand to rotate the nut 501 so that the nut 501 engages with the thread of the threaded rod 303 and pulls the threaded rod 303 downward;

[0037] When clamping and fixing the prefabricated bridge pier, the control rod 502 is held by hand to rotate the nut 501 to engage the threaded rod 303, so that the threaded rod 303 moves downward under the action of the thread, so that the tension block 301 at the top of the threaded rod 303 pulls the clamping plate 2 to move downward, so that the hinge shaft 201 of the clamping plate 2 rotates inside the hinge hole 102, so that the clamping plate 2 is close to the prefabricated bridge pier for clamping, and at the same time the rotating mechanism 4 rotates to adapt to the rotation angle of the clamping plate 2, which is simple to operate and convenient for clamping and fixing the prefabricated bridge pier;

[0038] Moreover, when the threaded rod 303 is pulling the clamping plate 2, it can form a force-saving lever, making the overall clamping more secure, and the clamping plate 2 is tilted and clamped on the outer wall of the pier, making the clamping plate 2 less likely to break.
