Description

Flat floor anti-slip device of car elevator Technical Field The utility model relates to the technical field of elevator cars, in particular to a flat floor anti-slip device of an elevator car. Background The lifting action of the elevator often depends on the rotation of an elevator cable roller arranged at the top of a flat floor, namely, the elevator can be lifted by winding and rolling the cable through forward rotation of the elevator cable roller, and can be lowered by releasing the cable through reverse rotation of the elevator cable roller, so that a sliding prevention device is required to be arranged in order to prevent the elevator cable roller from sliding during working. Through retrieving, the patent of publication number CN216336006U discloses a flat layer anti-slip device of car elevator, including elevator cable gyro wheel, the cable groove has been seted up to the inboard of elevator cable gyro wheel, the axis of rotation slot has been seted up to the inside of elevator cable gyro wheel, the inside fixed joint of axis of rotation slot has activity main shaft, dysmorphism card axle, joint board. Above-mentioned prior art, because the activity main shaft does not possess the easy swift current condition that takes place of auto-lock performance, it is fixed through increasing anti-slip subassembly, can effectively joint activity gyro wheel, prevents that the gyro wheel activity from sliding down and causing personnel's damage, but this technical means is controlled comparatively loaded down with trivial details, inconvenient operation, and the practicality is relatively poor, and elevator cable gyro wheel can constantly receive the wearing and tearing of hawser under long-time operating condition and lead to its surface to appear the condition of generating heat. Disclosure of utility model The utility model aims to solve the defects in the prior art and provides a flat floor anti-slip device of a car elevator. In order to achieve the above purpose, the present utility model adopts the following technical scheme: The flat floor anti-slip device of the car elevator comprises two supporting seats, a self-locking control mechanism and a transmission mechanism, wherein the two supporting seats are rotatably provided with the same main shaft, and elevator cable rollers which are equidistantly distributed are arranged on the main shaft; The outer walls of the tops of the two supporting seats are fixedly connected with the same guide rail, and a reciprocating cooling mechanism is arranged at the top of the guide rail; The self-locking control mechanism comprises a fixed cover fixedly connected to the side wall of one supporting seat, a stepping motor fixedly installed on the outer wall of one side of the fixed cover, a worm fixedly sleeved on the output shaft of the stepping motor and a worm wheel fixedly sleeved on one end of the main shaft.
