Meanwhile, the V-shaped guide rail mechanism 400 is utilized to increase the sliding contact area, has a self-centering function, and is beneficial to improving the precision of the suspended wedge and increasing the structural strength and rigidity of the suspended wedge.

Preferably, the first wear assembly 510 and the third wear assembly 530 in this embodiment are copper-impregnated graphite wear plates. The copper-inlaid graphite wear-resistant plate has good wear resistance, can provide longer service life in friction and abrasion environments, is beneficial to reducing the abrasion degree of the suspension wedge and prolongs the service life of the suspension wedge. The graphite has self-lubricating property, can reduce friction coefficient in the working process, reduce energy loss, improve working efficiency, reduce the working force requirement on the suspension wedge and improve the performance of the suspension wedge.

Specifically, the upper base mechanism 100 in this embodiment includes an upper base block 110, a baffle plate 120 and a buffer block 130, the upper base block 110 is provided with a groove 111, the guide mechanism 200 is disposed in the groove 111, the baffle plate 120 is mounted on a side surface of the upper base block 110, the baffle plate 120 is used for blocking the guide mechanism 200 from sliding off the groove 111, and the buffer block 130 is mounted on a surface of the baffle plate 120 facing the upper base block 110. By providing the groove 111 on the upper base block 110 and disposing the guide mechanism 200 in the groove 111, stable positioning of the guide mechanism 200 relative to the upper base block 110 can be ensured, so as to improve accuracy and stability of the entire suspension wedge. The baffle 120 is disposed at the side of the upper base block 110, and is used for blocking the guide mechanism 200 from sliding away from the groove 111, so as to prevent accidental detachment or deviation during movement, and maintain the normal working state of the suspended wedge. The buffer block 130 is mounted on the baffle 120 facing the upper base block 110, which is helpful to absorb part of impact force during wedge movement, reduce vibration and noise, and improve the working stability of the suspended wedge.

Specifically, the guide mechanism 200 in the present embodiment includes a guide block 210, a return assembly 220 and a safety limit screw 223, where the guide block 210 is slidably disposed in the groove 111, one end of the return assembly 220 abuts against the guide block 210, the other end of the return assembly 220 abuts against the groove wall of the groove 111, and the safety limit screw 223 is mounted on the first wear-resistant assembly 510 and is inserted into the side surface of the guide block 210. The guide block 210 is slidably disposed in the groove 111, so that stable positioning of the guide block 210 with respect to the upper base block 110 can be ensured, and overall accuracy and stability of the suspension wedge can be improved. The return assembly 220 returns to the original position after the suspension wedge moves, ensuring normal movement of the suspension wedge. The safety limit screw 223 is mounted on the first wear-resistant component 510 and inserted into the side surface of the guide block 210, and is in a two-side lock limit screw mode, so that the occupied space of the safety limit mechanism is reduced on the premise of ensuring the use function, and meanwhile, the safety limit screw is easy to process, and is beneficial to reducing the processing cost. The safety limiting mechanism is arranged to help prevent the suspended wedge from exceeding the specified range in the use process, so that the safety of the whole system is improved.

Specifically, the return assembly 220 in this embodiment includes an elastic member 221 and a top block 222, and the top block 222 is mounted on one end of the elastic member 221 facing the wall of the groove 111.

When the suspension wedge is pushed by an external force such that the guide block 210 moves relative to the upper base block 110, the elastic member 221 is deformed by pressing or stretching, and the top block 222 moves accordingly. Once the external force is reduced or eliminated, the elasticity of the elastic member 221 may return the return assembly 220 to the initial state. The elastic restoring force of the elastic member 221 restores the guide block 210 to the initial position of the groove 111, ensuring that the suspension wedge returns to the ready state. The provision of the ejector blocks 222 helps to maintain the relative position of the return assembly 220, making the return process more stable and reliable, preventing excessive extrusion or deformation of the return assembly 220, and thus preventing the upper base body from being ejected out of the pocket.

The nitrogen spring is used as the elastic piece 221, and the nitrogen spring has good compressibility and elastic recoverability, is compact in structure, is beneficial to reducing the occupied space of the return element, ensures that the whole volume of the suspension wedge is smaller, and is suitable for a limited space environment. The nitrogen spring has stronger elastic force, can provide sufficient return force, ensures that the suspended wedge quickly returns to the initial position after the action of external force, and further keeps the stability and the precision of the system. Because the nitrogen spring has compactness, the volume of whole suspension slide wedge can reduce, can save space, has also improved the structural strength of slide wedge, because smaller volume is usually higher to the requirement of structure.

The V-shaped guide rail mechanism 400 has a self-centering function, that is, during the movement process, the matching of the concave V-shaped guide rail 410 and the convex V-shaped guide rail 420 can automatically maintain the accuracy of the relative position, which is helpful for improving the accuracy of the suspension wedge, ensuring that the suspension wedge does not deviate during the movement, ensuring that the suspension wedge is more stable during the movement, bearing larger working force and enhancing the endurance of the whole system.

Further, the suspension wedge in this embodiment further includes a forced pull-back hook 700, one end of the forced pull-back hook 700 is overlapped with the sliding block 300, and the other end of the forced pull-back hook 700 is overlapped with the driving block 600. The forced pull-back hook 700 can ensure that the connection between the sliding block 300 and the driving block 600 is firmer, one end is overlapped with the sliding block 300, the other end is overlapped with the driving block 600, and when the external force is reduced or eliminated, the sliding block 300 and the driving block 600 are forced to be pulled back to the initial position, so that the suspended wedge is ensured to be quickly returned to the state of preparation work. The provision of the forced pullback hook 700 helps to fully utilize space and reduce the volume of the suspension wedge. Through compact connection design, the overall size of the system is effectively reduced, and the system is more suitable for limited space environment.

Preferably, the concave V-shaped guide 410 in this embodiment is a steel concave V-shaped guide, and the convex V-shaped guide 420 is a copper graphite convex V-shaped guide.
