Elevator sliding guide shoe and machining process thereof

Abstract

The invention discloses an elevator sliding guide shoe. The elevator sliding guide shoe comprises a shoe base, a left mounting frame, a right mounting frame and a shoe liner; sliding rail plates are arranged on the upper portion and the lower portion of the rear side wall in the shoe base; sliding groove bases are arranged on the upper portion and the lower portion of the rear side of each mounting frame; the sliding groove bases are connected to the corresponding sliding rail plates in a sliding manner; the shoe liner is clamped in the mounting frames; first bolts on the side edges of the mounting frames are in screw joint to the shoe liner; and long bolts penetrate the shoe base and then are in screw joint to a middle reinforcing rib plate. According to the elevator sliding guide shoe, the sliding groove bases are connected to the corresponding sliding rail plates in the sliding manner, and therefore when an elevator car moves up and down and a guide rail in an elevator shaft and the shoe liner generate friction, due to the fact that the sliding groove bases are connected to the corresponding sliding rail plates in the sliding manner, the up-down positions of the mounting frames can be limited, and then the mounting frames and the shoe liner are prevented from being integrally disengaged; and the shoe liner is clamped in the mounting frames, the first bolts on the side edges of the mounting frames are in screw joint to the shoe liner, and therefore the mounting firmness of the shoe liner and the mounting frames can be improved, and subsequent demounting and replacement are facilitated.

Description

technical field [0001] The invention belongs to the technical field of sliding guide shoes and, in particular, relates to an elevator sliding guide shoe and a processing technology thereof. Background technique [0002] Usually, the elevator comprises vertical guide rails arranged in the elevator shaft, by which guide rails the elevator car is adapted to run up and down in the elevator shaft. The sliding guide shoe is installed on the side, top edge and bottom edge of the elevator car or the car hanger. The structure of the existing sliding guide shoe is complicated, the installation of the shoe lining is not firm, and it is inconvenient to disassemble, which is not conducive to subsequent maintenance Replacement, when the elevator car moves up and down and the guide rail in the elevator shaft rubs against the shoe lining, it is easy to cause the shoe lining to detach, resulting in excessive friction between the sliding guide shoe and the guide rail. Therefore, we propose an...

The sliding guide shoe is installed on the side, top edge and bottom edge of the elevator car or the car hanger. The structure of the existing sliding guide shoe is complicated, the installation of the shoe lining is not firm, and it is inconvenient to disassemble, which is not conducive to subsequent maintenance Replacement, when the elevator car moves up and down and the guide rail in the elevator shaft rubs against the shoe lining, it is easy to cause the shoe lining to detach, resulting in excessive friction between the sliding guide shoe and the guide rail. Therefore, we propose an elevator sliding guide shoe and its processing process, to solve the problems mentioned in the above background technology
