Description

Technical Field

[0001] The utility model relates to the field of rail transportation, in particular to an anti-slip clamping shear hinge. Background Art

[0002] In the fields of civil engineering, mechanical engineering, and transportation engineering, shear hinges are widely used as a key structural connection component in the construction of infrastructure such as bridges, buildings, and rail transit. Its main function is to absorb and disperse these forces through its own elastic deformation when the structure is subjected to shear force, thereby protecting the main structure from damage. However, traditional shear hinges often have problems such as unstable clamping and easy slippage during use, especially when subjected to large external forces. These problems are particularly prominent.

[0003] Traditional shear hinges are usually fixed to the main structure by simple bolt connection or welding. Although this method can achieve connection to a certain extent, it often causes problems such as loose connection and slippage when facing complex external forces. In addition, traditional shear hinges are also insufficient in clamping. Their clamping force is often not stable enough and is easily affected by the external environment and use conditions, resulting in poor clamping effect.

[0004] Therefore, based on the above search and in combination with the prior art, an anti-slip clamping shear hinge is proposed to solve the above problem. Utility Model Content

[0023] Example 1: Please refer to Figure 1 to Figure 5 , an anti-slip clamping shear hinge, comprising a floating plate 1 and a shear hinge body 2, the floating plate 1 serving as an installation base, the top surface of which is provided with a shear hinge body 2, the bottom surface of the shear hinge body 2 is fixedly installed with a connecting rod 3, the connecting rod 3 passes through the top surface of the floating plate 1 and extends to the bottom thereof, and a fixing block 4 is fixedly installed on the bottom surface, so that a stable connection is formed between the shear hinge body 2 and the floating plate 1, a nut 5 is fixedly installed on the top surface of the shear hinge body 2, which provides an interface for connecting with an external structure, and at the same time, in order to increase the contact area and stability between the shear hinge body 2 and the floating plate 1, a pad 6 is arranged between the bottom surface of the shear hinge body 2 and the top surface of the floating plate 1, and in order to increase the friction between the pad 6 and the floating plate 1, an anti-slip pad 17 is fixedly installed on the bottom surface of the pad 6 to ensure that the shear hinge is not easy to slip during use, and in order to further enhance the clamping and anti-slip capabilities of the shear hinge, a sliding assembly and a driving member are arranged on the shear hinge body 2;

[0024] See also Figure 1 to Figure 4 , an anti-slip clamping shear hinge, the sliding assembly includes two fixed plates 7, which are respectively installed on the top surface of the shear hinge body 2 and located on both sides of the nut 5. A slide groove 8 is opened on the bottom surface of each fixed plate 7, and a reciprocating screw rod 9 is rotatably connected in the slide groove 8. Two sliders 10 are threadedly connected to the reciprocating screw rod 9. A clamping plate 11 is fixedly installed on the bottom surface of the slider 10. In this way, when the reciprocating screw rod 9 rotates, the slider 10 and the clamping plate 11 will move along the slide groove 8 to achieve the clamping of the floating plate 1;

[0025] See also Figure 3 and Figure 4, an anti-slip clamping shear hinge, the driving member includes a worm 14, which is arranged on the shear hinge body 2, and an adjusting button 15 is fixedly installed at the center. A worm wheel 16 is fixedly installed on the outer surface of the two reciprocating screws 9, and the worm wheel 16 is meshed with the worm 14. By rotating the adjusting button 15, the worm 14 can be driven to rotate, and then the two worm wheels 16 and the reciprocating screw 9 can be driven to rotate synchronously to realize the opening and closing of the clamping plate 11;

[0026] See also Figure 1 to Figure 5 , an anti-slip clamping shear hinge, a serrated pad 12 is fixedly installed on the surface of the clamping plate 11 facing the floating plate 1 to increase the stability of the clamping and the anti-slip effect. In addition, a mounting groove 13 is opened on the top surface of the shear hinge body 2, and a worm 14 is rotatably connected to the side wall of the mounting groove 13 to ensure the stable rotation of the worm 14;

[0027] Working principle:

[0028] First, the shear hinge body 2 forms a stable connection with the floating plate 1 through the connecting rod 3 and the fixing block 4. The pad 6 is arranged between the bottom surface of the shear hinge body 2 and the top surface of the floating plate 1 to increase the contact area and stability. The anti-skid pad 17 installed on the bottom surface of the pad 6 further enhances the friction between the pad 6 and the floating plate 1, thereby effectively preventing the shear hinge from slipping during use.

[0029] When a clamping operation is required, the adjusting knob 15 is rotated to drive the worm 14 to rotate. Since the worm 14 is meshed with the two worm wheels 16 , the rotation of the worm 14 will drive the two worm wheels 16 to rotate synchronously. The rotation of the worm gear 16 further drives the reciprocating screw rod 9 threadedly connected thereto to rotate in the slide groove 8. Since the slider 10 is threadedly connected to the reciprocating screw rod 9, the rotation of the reciprocating screw rod 9 will cause the slider 10 to reciprocate along the slide groove 8. As the slider 10 moves, the clamping plate 11 fixed on its bottom surface will also move accordingly. Since a serrated pad 12 is installed on the surface of the clamping plate 11 facing the floating plate 1, this can not only increase the stability of clamping, but also effectively prevent sliding during the clamping process. When the two clamping plates 11 approach the floating plate 1, they will clamp the floating plate 1 together to achieve stable fixation thereof. The utility model realizes the stable clamping and anti-skid function of the floating plate 1 through ingenious mechanical structure design and working principle. The shear hinge is not only simple in structure and easy to operate, but also has stable clamping and good anti-skid effect, and has broad application prospects.
