[0002] An elevator is a vertical lift powered by an electric motor, used to carry people or goods in multi-story buildings. As a vertical transportation tool, elevators have become an important and indispensable construction equipment in high-rise buildings and public places.

[0003] At present, the elevators installed in old buildings have poor structural stability due to their age. The elevator car is prone to accidental shaking during movement, which poses a great safety hazard to passengers. Therefore, it is necessary to develop an auxiliary device for improving the smoothness of elevator car operation to reduce the fear of passengers. Summary of the invention

[0004] The purpose of the present invention is to provide an auxiliary device for improving the smoothness of elevator car operation. By installing slide rails and fixed seats on the hoistway and the car body respectively, and utilizing the cooperation of gears and racks, the problem of shaking or unstable running speed during the operation of elevators in existing old buildings is solved.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The present invention is an auxiliary device for improving the running smoothness of an elevator car, comprising a shaft equipped with a car body; a slide rail is respectively installed on the opposite inner side walls of the shaft; a first groove is provided on a surface close to the two slide rails; a second groove is respectively provided on an opposite side of the first groove; a mounting groove is provided on a surface of the first groove; a fixed seat is respectively fixed on an opposite side of the car body; a rotating shaft is rotatably connected to the fixed seat; a gear is fixed on the rotating shaft; a rack is meshed on the gear; the rotating shaft is cooperatively inserted in the second groove; the gear is cooperatively arranged in the first groove; and the rack is installed in the mounting groove.

[0007] Furthermore, the cross section of the slide rail is a T-shaped structure; the slide rail is made of stainless steel or carbon steel.

[0008] Furthermore, a surface of the slide rail is provided with a plurality of through holes arranged side by side.

[0009] Furthermore, the fixing seat is a U-shaped structure.

[0010] Furthermore, a deceleration strip is installed on one surface of the slide rail; a bidirectional screw rod is installed in the fixed seat; one end of the bidirectional screw rod extends through and extends to one side of the fixed seat and is connected to a power mechanism; a first nut and a second nut are correspondingly matched on the circumferential side of the bidirectional screw rod; a clamping rod is fixed on each of the first nut and the second nut.

[0011] Furthermore, the deceleration strip is made of composite rubber; a third groove matching the position of the first groove is formed on one surface of the deceleration strip.

[0012] Furthermore, a plurality of limiting posts are arranged side by side on one surface of the deceleration strip; and a plurality of limiting holes matching with the limiting posts are opened side by side on one surface of the slide rail.

[0013] Furthermore, the power mechanism adopts a stepping motor; the power mechanism is connected to the side of the car body by bolts.

[0014] Furthermore, a plurality of first protrusions are evenly distributed on a relative surface of the third groove; and a plurality of second protrusions are evenly distributed on an end surface of the gear.

[0015] Furthermore, one end of the limiting column is fixedly connected to a column cap.

[0017] 1. The present invention solves the problem of shaking or unstable running speed during the operation of elevators in existing old buildings by installing slide rails and fixed seats on the hoistway and the car body respectively and utilizing the mutual cooperation of gears and racks, thereby effectively reducing the fear in the hearts of passengers.

[0018] 2. The present invention sets a power mechanism to drive the bidirectional screw to rotate, the first nut and the second nut move close to each other, and the two clamping rods tightly clamp the deceleration bar. The deceleration bar generates a certain friction on the gear end face under the action of the clamping force, thereby effectively improving the stability of the movement of the car body and ensuring the practical value of the device.
