Embodiment Construction

[0027] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0028] see figure 1 , figure 2 , image 3, the elevator safety gear structure in this embodiment is used to stop the car 3 on the guide rail 4 when the suspension rope is broken or the car 3 is overspeed, including the first wedge block 1 and the first wedge block 1 The needle roller row 11 at the lower end of the inner side, the second wedge block 2 arranged at the lower end of the needle roller row 11, and the lifting rod 22 arranged at the upper end of the second wedge block 2 are used to keep one end of the first wedge block 1 parallel to one end of the guide rail 4 And the fixed piece with constant distance between the two, the connecting piece that is used to rotate the other end of the first wedge block 1 and the...

Abstract

The invention provides an elevator safety tongs structure, and belongs to the technical field of safety tongs. The elevator safety tongs structure comprises first wedge blocks, roller pin rows, secondwedge blocks, a lifting rod, fixing pieces, connecting pieces and expansion extrusion pieces. According to the elevator safety tongs structure, through each fixing piece, one end of the correspondingfirst wedge block and one end of a guide rail are kept parallel and the distance between the end of the first wedge block and the end of the guide rail is unchanged, and thus the situation that the first wedge block is inclined so that it cannot be convenient for the corresponding second wedge block to extend to the position between the first wedge block and the guide rail to stop the first wedgeblock is avoided; through each connecting piece, the other end of the corresponding first wedge block and the corresponding second wedge block are respectively and rotatably connected to an elevatorcar, and the lifting rod pulls the second wedge block to move towards the direction close to the first wedge block; and when each expansion extrusion piece is impacted by the lower end of the elevatorcar, the expansion extrusion piece expands and extrudes the lower end of the corresponding second wedge block to make the second wedge block move towards the direction close to the first wedge block,so that the second wedge block is accelerated to move towards the direction of the first wedge block, and the efficiency of stopping the elevator car is improved.

Description

technical field [0001] The invention belongs to the technical field of safety gear and relates to an elevator safety gear structure. Background technique [0002] The safety gear is an important safety component in elevator equipment. It is used to stop the car in an emergency and clamp the car on the elevator guide rail when the elevator has faults such as overspeed and broken rope. However, if the car is skewed, the safety gear will also be skewed relative to the guide rail, so the safety gear cannot safely stop the car on the guide rail. [0003] Chinese patent CN209583321U discloses a progressive elevator safety tongs, including two mounting plates, the two ends of the two mounting plates are connected by reinforcing columns, the two ends of the mounting plate are equipped with fixed blocks, and the inner walls of the two fixed blocks are clamped with sliding clamps. The damping plate is installed on the inner wall of the sliding pliers, and the guide plate is installed...
