Technical Field

The invention relates to the technical field of elevators, in particular to an elevator with adjustable guide shoe spacing and a guide shoe spacing adjusting method.

Background

An elevator is a fixed lifting device. The vertical lift elevator has a car that runs between at least two vertical rows of rigid guide rails or guide rails with an angle of inclination of less than 15 °. The size and the structural form of the car are convenient for passengers to access or load and unload goods. The elevator brings great convenience to the life of people, and is already integrated into the daily life of people.

However, in some cases, the height of the top floor of the elevator shaft is made lower due to various factors such as the limit of the height and the cost. When the top layer of the shaft is too low, in order to be matched with the top layer of the shaft in height and prevent the elevator from colliding with the top part of the shaft or a pit, the car frame of the elevator can be correspondingly shortened, and therefore the distance between the guide shoes above and below the car is too small. When the distance between the guide shoes is too small, the guide shoes are very large in stress and easy to damage, vibration and noise can be generated when the elevator runs, the running effect is poor, and the elevator can be directly caused to fail to run in serious cases.

Therefore, it is necessary to design an elevator with adjustable guide shoe spacing to solve the above problems.

Disclosure of Invention

Aiming at the defects in the prior art, the invention aims to solve the problems that the distance between an upper guide shoe and a lower guide shoe of an elevator is too small, the guide shoes are easy to damage and the running effect of the elevator is poor, and provides the elevator with the adjustable guide shoe distance and the guide shoe distance adjusting method, so that the distance between the guide shoes can be adjusted according to the running condition of the elevator, the guide shoes are protected, and the running effect of the elevator is improved.

In order to solve the technical problem, the technical scheme adopted by the invention is as follows:

an elevator with adjustable guide shoe space comprises an elevator guide rail, a car frame, a car and an elevator control system; the lift car is connected with a car frame, the car frame comprises a car frame upright post and guide shoes positioned at two ends of the car frame upright post, and the guide shoes are connected with the elevator guide rail in a sliding fit manner;

two upright post slide rails are vertically arranged on the car frame upright post, the two upright post slide rails respectively extend from the middle part to two ends of the car frame upright post, and a space is reserved between the two upright post slide rails; a telescopic frame is vertically arranged between the two upright post slide rails, a telescopic device is vertically arranged in the middle of the telescopic frame, and two ends of the telescopic device are hinged with the telescopic frame together, so that the telescopic device can drive the two telescopic frames to contract or expand synchronously; the two guide shoes are respectively connected with the two ends of the telescopic frame through a linkage rod; a guide sliding block matched with the upright post sliding rail is arranged at one end, close to the telescopic device, of the linkage rod, a first band-type brake is further arranged on the linkage rod, and the first band-type brake is fixedly connected with the guide sliding block and is arranged on the upright post sliding rail in a band-type mode;

the elevator control system is characterized by further comprising an upper position detection sensor arranged at the top of the elevator guide rail and a lower position detection sensor arranged at the bottom of the elevator guide rail, wherein the upper position detection sensor, the lower position detection sensor, the telescopic device and the first band-type brake are all connected with the elevator control system.

The telescopic frame and the telescopic device are arranged on the car frame upright column, and the guide shoes are connected with the telescopic frame through the linkage rod, so that when the telescopic frame is driven by the telescopic device to contract or expand, the upper guide shoes and the lower guide shoes connected with the telescopic frame can be driven to synchronously move, and when the elevator reaches the top of a well or the bottom of the well, the telescopic device contracts to reduce the distance between the upper guide shoes and the lower guide shoes so as to adapt to the condition of lower height of the top layer of the well; when the elevator normally operates, the telescopic device is unfolded to enlarge the distance between the upper guide shoe and the lower guide shoe, so that the stress of the guide shoes is reduced, and the guide shoes are not easy to damage. Not only protects the guide shoe, but also improves the running effect of the elevator.

Further, the device also comprises a supporting device; the two supporting devices are respectively arranged at the upper end and the lower end of the lift car; the supporting device comprises a supporting slide rail, and the length direction of the supporting slide rail is vertical to the car frame upright post; the first sliding block and the second sliding block are arranged on the supporting sliding rail, the first sliding block and the second sliding block are respectively connected with a second band-type brake, and the second band-type brakes are respectively arranged on the supporting sliding rail in a band-type mode; a first support arm is hinged on the first sliding block, and the other end of the first support arm is hinged with the corresponding upper guide shoe or the corresponding lower guide shoe; a second support arm is hinged on the second sliding block, and the other end of the second support arm is hinged with the first support arm; the second band-type brake is connected with the elevator control system. Like this, because first supporting arm with lead boots articulated, when telescoping device and expansion bracket expand, lead boots and to the direction motion that deviates from drive first supporting arm and second supporting arm to the direction motion of car stand and make first supporting arm and second supporting arm expand to through the locking of second band-type brake, form the support to leading boots, make the boots of leading after expanding more stable, increase the stability of elevator operation.

Furthermore, the expansion bracket is a diamond expansion bracket formed by connecting a plurality of connecting frames, the connecting frames are formed by connecting rods which are distributed in a cross shape and hinged together, and two connecting rods of two adjacent connecting frames are also hinged. Therefore, when the telescopic device is contracted or expanded, the rhombic telescopic frame can be driven to synchronously move with the telescopic device, and the design is reasonable.

Furthermore, the telescopic device is an electric telescopic mechanism, an air cylinder or a hydraulic cylinder, can be unfolded and contracted, and is simple in structure and reliable in operation.

Furthermore, the electric telescopic mechanism adopts an electric cylinder or an electric push rod, and has simple structure and reliable operation.

Further, the guide shoe and the linkage rod are welded and fixed. The welding can increase the stability of elevator operation, makes the elevator operation more reliable.

Furthermore, the number of the guide sliding blocks is two, and the first band-type brake is located between the two guide sliding blocks and fixedly connected with the two guide sliding blocks. The two guide sliding blocks can ensure that the telescopic frame connected with the two guide sliding blocks moves along the set direction, so that the elevator can accurately run.
