Mechanical properties are key issues in the research and application of engineering materials and the main basis in the design of engineering structures and components. Necessary spot checks should be carried out on the mechanical properties of finished rubber bearings before engineering use.

[0003] When testing bridge bearings using a testing machine, during the test, the rubber bearing needs to be carried to the lower bearing plate of the testing machine. The testing machine slowly applies pressure, and the upper bearing plate presses on the rubber bearing to conduct mechanical tests on the rubber bearing, such as the compressive elastic modulus test.

[0004] The outside of the rubber bearing is rubber, and the inside is a laminated structure of one layer of rubber and one layer of iron plate. Its shape is cylindrical or square, and the weight is generally 100 - 200 kg. When carrying the rubber bearing to the bearing plate, manual handling is generally used, which requires the joint efforts of multiple people, is time-consuming and laborious, and has a high working intensity. There is also a method of using a traveling crane in cooperation with magnetic adsorption fixation for handling, but the traveling crane has requirements for the use space and can only be used when there is no obstruction above the handling space, and there are safety hazards during the use of the traveling crane.

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. All directional indications (such as up, down, left, right, front, back...) in the present utility model are only used to explain the relative position relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0021] As Figures 1-3 shown, this embodiment provides a mobile rubber bearing gripper, which includes a mobile base 1. Travel wheels are installed on the mobile base 1. Above the mobile base 1, there is a top plate 2. At one end of the top surface of the top plate 2, there is a pusher 3 for convenient pushing by workers. At the same time, four travel wheels are installed under the mobile base 1, which are respectively located at the four corners of the mobile base 1. Two of the travel wheels located on one side of the pusher 3 are universal wheels 4, and the other two travel wheels are directional wheels 5, which is convenient for steering the mobile base 1. The top plate 2 is connected to the mobile base 1 through a first hydraulic rod 6 to facilitate the lifting of the top plate 2. And at the four corners of the top surface of the mobile base 1, there are fixed connection optical rods 7, and the optical rods 7 are slidably connected to the top plate 2 to limit the lifting of the top plate 2 by using the optical rods 7. In this example, one first hydraulic rod 6 is provided. At the bottom surface of the top plate 2, there is a support ring 9 fixedly connected through a connecting rod 8. Four crankshaft rods 10 distributed in a circular array are movably connected to the support ring 9. At the lower end of the crankshaft rod 10, there is a clamping member 11. The upper end of the crankshaft rod 10 is movably connected to a driving disk 20. A second hydraulic rod 12 is installed on the top plate 2, and the second hydraulic rod 12 is connected to the driving disk 20.

[0022] An opening groove 13 is provided on one side of the mobile base 1. The opening groove 13 is located below the support ring 9. The setting of the opening groove 13 facilitates pushing the mobile base 1 to both sides of the rubber bearing, so that the clamping member 11 is located above the rubber bearing, which is convenient for grasping the rubber bearing. And a step groove 14 is provided on the opening groove 13, and a protection plate 15 is detachably supported on the step groove 14. After grasping the rubber bearing, the protection plate 15 is placed into the step groove 14 to support the rubber bearing by using the protection plate 15 to prevent the rubber bearing from falling off during the movement. And a storage rack 16 is provided at one end of the mobile base 1. The storage rack 16 is used to place the protection plate 15, and the protection plate 15 is placed on the storage rack 16 before grasping the rubber bearing.

[0023] The inner wall of the support ring 9 is provided with first shaft seats 17 distributed circumferentially. The bent portion of the crankshaft rod 10 is movably connected to the first shaft seats 17. The side surface of the drive disc 20 is provided with second shaft seats 18 distributed circumferentially. The upper end of the crankshaft rod 10 is movably connected to the second shaft seats 18. The clamping member 11 is of an arc-shaped structure, and the clamping member 11 is movably connected to the lower end of the crankshaft rod 10 through a third shaft seat 19. The clamping member 11 can rotate vertically and horizontally relative to the crankshaft rod 10. After the lower ends of the crankshaft rod 10 approach each other inwardly, the clamping member 11 can rotate adaptively relative to the crankshaft rod 10, thereby increasing the contact surface between the clamping member 11 and the side surface of the rubber bearing, and further improving the grasping firmness of the rubber bearing. It is mainly applicable to the grasping of circular rubber bearings.

[0024] Its working principle is as follows: When the first hydraulic rod 6 drives the top plate 2 to descend, the second hydraulic rod 12 drives the drive disc 20 to descend, so that the clamping members 11 move away from each other under the drive of the crankshaft rod 10. After the clamping members 11 descend to the side surface of the rubber bearing, the second hydraulic rod 12 drives the drive disc 20 to rise, so that the clamping members 11 approach each other to grasp the rubber bearing. The first hydraulic rod 6 drives the top plate 2 to rise to lift the rubber bearing. The worker pushes the moving base 1 to drive the rubber bearing to move to the designated position. It can achieve single-person handling, with simple operation, time-saving and labor-saving. It can grasp and handle the rubber bearing in a narrow space and at a low altitude, improving the safety performance.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
