Description

Technical Field

[0001] The utility model relates to the technical field of hoisting fixtures, in particular to a scissors-type hoisting fixture for bridge rubber bearings. Background Technique

[0002] Bridge rubber bearings are key components used to support and buffer bridge structures. They play an important role in ensuring the stability, comfort and durability of bridges. Rubber bearings are mainly composed of rubber and steel plates, and have excellent elasticity and seismic resistance. Rubber bearings are usually installed between the beam bottom of the bridge and the pier to ensure smooth contact between various parts of the bridge. When installing rubber bearings, it is necessary to ensure their flatness and perpendicularity to avoid a decrease in the bearing performance due to improper installation. When installing rubber bearings, a scissors-type hoisting fixture is often required. However, the hoisting fixtures in the prior art often have certain limitations on the bearing capacity and size of the bearings and are not applicable to all types of bearings. Moreover, they usually only clamp the periphery of the bearing, and there is a possibility of unstable clamping if the operation is improper, thus bringing certain risks to the construction. Therefore, it is necessary to propose a scissors-type hoisting fixture for bridge rubber bearings. Content of the Utility Model

[0003] The purpose of the utility model is to propose a scissors-type hoisting fixture for bridge rubber bearings aiming at the problems existing in the background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The technical solutions of the utility model will be further described below with reference to the drawings and specific embodiments.

[0020] Embodiment

[0021] As Figures 1 to 3As shown in the figure, a lifting fixture for a scissors - type bridge rubber bearing proposed by the present utility model includes a mounting plate 1. On the top surface of the mounting plate 1, a carrier plate 14 is provided, and the top surface of the mounting plate 1 is fixedly connected to the bottom surface of the carrier plate 14. On the top surface of the carrier plate 14, a hook 15 is provided, and the top surface of the carrier plate 14 is fixedly connected to the bottom surface of the hook 15. By setting the hook 15, it is convenient to connect with equipment such as tower cranes. On the front side of the mounting plate 1, a first pneumatic cylinder push rod 2 is provided, and the front side of the mounting plate 1 is fixedly connected to the rear side of the first pneumatic cylinder push rod 2. At the output end of the first pneumatic cylinder push rod 2, a moving block 3 is provided, and the output end of the first pneumatic cylinder push rod 2 is fixedly connected to the top surface of the moving block 3. A trapezoidal groove is formed on the front side of the mounting plate 1. On the rear side of the moving block 3, a trapezoidal strip 16 is provided, and the rear side of the moving block 3 is fixedly connected to the front side of the trapezoidal strip 16. The trapezoidal strip 16 is slidably connected to the trapezoidal groove. By guiding and limiting the trapezoidal strip 16 through the trapezoidal groove, the running track of the moving block 3 is guided and limited, so that the moving block 3 always maintains a straight - line running state;

[0022] On the left and right sides of the moving block 3, side plates 4 are provided, and the moving block 3 is fixedly connected to the side plates 4. On the front side of each side plate 4, a set of first connecting rods 5 is rotatably provided, and each set of first connecting rods 5 is arranged in parallel. On the front side of the mounting plate 1, two column platforms 6 are provided, and the front side of the mounting plate 1 is fixedly connected to the column platforms 6. The two column platforms 6 are respectively located at symmetrical positions on the left and right sides of the first pneumatic cylinder push rod 2. On the front side of each column platform 6, a second connecting rod 7 is rotatably provided. By restricting the top position of the second connecting rod 7 through the column platform 6, the second connecting rod 7 can only rotate around the column platform 6 as the center. The bottom ends of the two second connecting rods 7 are respectively rotatably connected to the front sides of the two upper - side first connecting rods 5. At the mutually - remote ends of the two sets of first connecting rods 5, third connecting rods 8 are rotatably provided, and the third connecting rods 8 are always in a vertical state;

[0023] When the output end of the first pneumatic cylinder push rod 2 contracts, it drives the moving block 3 to move upward. Thus, it can drive the two side plates 4 to move upward, and further drive the two sets of first connecting rods 5 to move. However, the two upper - side first connecting rods 5 are restricted by the second connecting rods 7. Therefore, at the ends where the two sets of first connecting rods 5 are connected to the side plates 4, they move upward, while the other ends move downward. Since the connection points of the side plates 4, the first connecting rods 5, and the third connecting rods 8 can form a parallelogram, the third connecting rods 8 are always in a vertically - downward state. At the bottom end of each third connecting rod 8, an L - shaped rod 9 is provided, and the third connecting rod 8 is fixedly connected to the L - shaped rod 9. The two L - shaped rods 9 are arranged oppositely. On the mutually - close sides of the two L - shaped rods 9, clamping plates 10 are provided, and the L - shaped rods 9 are fixedly connected to the clamping plates 10. On the mutually - close sides of the two clamping plates 10, anti - slip pads 17 are provided, and the clamping plates 10 are fixedly connected to the anti - slip pads 17;

[0024] On one side of the two splints 10 away from each other, there are cylinder push rods two 11 provided. The splints 10 are fixedly connected to the cylinder push rods two 11. The output end of the cylinder push rod two 11 is provided with a push-pull plate 12. The output end of the cylinder push rod two 11 is fixedly connected to the push-pull plate 12. On the side of the push-pull plate 12 close to the cylinder push rod two 11, there is a support plate 13. The push-pull plate 12 is fixedly connected to the support plate 13. The top surface of the support plate 13 is slidably connected to the bottom surface of the splint 10. T-shaped strips 18 are provided on the bottom surfaces of the splints 10. The bottom surfaces of the splints 10 are fixedly connected to the top surfaces of the T-shaped strips 18. T-shaped grooves are formed on the top surfaces of the support plates 13. The T-shaped strips 18 are slidably connected to the T-shaped grooves. By the sliding connection between the T-shaped strips 18 and the T-shaped grooves, it can ensure that the support plate 13 moves in a straight line and prevent the support plate 13 from separating from the splint 10.

[0025] In this embodiment, when using this device, move the device to the position of the support to be clamped, so that the two splints 10 are respectively located on both sides of the support. Then operate the cylinder push rod one 2. The output end of the cylinder push rod one 2 drives the moving block 3 to move upward. The movement of the moving block 3 will drive the side plate 4 to move upward. Then the movement of the side plate 4 will drive the connecting rod one 5 to move. The two connecting rods one 5 located on the upper side are limited by the two connecting rods two 7, so that the ends of the connecting rods one 5 away from the side plate 4 rotate, and the connecting rod three 8 always moves in a vertical state, thereby driving the L-shaped rods 9 to move closer to each other in a vertical state, so that the two splints 10 clamp the support between the two anti-slip pads 17. Then operate the cylinder push rod two 11. The output end of the cylinder push rod two 11 drives the push-pull plate 12 to move, so that the support plate 13 can be driven to move, and the support plate 13 moves to the bottom of the support to support the support.

[0026] The above specific embodiment is only a preferred embodiment of the present invention. Based on the technical solution of the present invention and the relevant revelations of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
