Description

A connecting support for a passenger elevator car frame column

Technical Field

The present application relates to the technical field of passenger elevator car structural components in the machinery manufacturing industry, and in particular to a connecting support for passenger elevator car frame columns, which is particularly suitable for the precise positioning and supporting functions of safety clamps and guide shoes at the bottom of elevator car frame columns of TP and TJ series single-car with machine room and single-car without machine room.

Background Art

Elevator is the general term for vertical transportation tools and fixed lifting equipment in buildings. Different types of elevators are usually required according to the height, purpose and passenger flow of the building. In terms of purpose, it is mainly composed of passenger elevators, cargo elevators, medical elevators, miscellaneous elevators, sightseeing elevators, vehicle elevators, ship elevators, construction elevators, etc. Passenger elevators are special elevators for transporting passengers. They require complete safety facilities and certain interior decoration. They are the most widely used elevators at present. With the popularization of high-rise buildings, the market application prospects of passenger elevators are extremely broad.

The elevator is mainly composed of a traction machine (winch), a guide system, a counterweight device, a safety device, an electric traction system, a signal control system, a hall door and a car. The working principle is that the two ends of the traction rope are connected to the car and the counterweight respectively, and are wound around the traction wheel and the guide wheel; the traction motor drives the traction wheel to rotate after the speed is changed by the reducer, and the traction force generated by the friction between the traction rope and the traction wheel is used to realize the lifting and lowering movement of the car and the counterweight to achieve the purpose of transportation. Therefore, the various functional parts of the elevator are installed in the shaft and machine room of the building respectively. Usually, the steel wire rope friction transmission is adopted. The steel wire rope passes around the traction wheel, and the two ends are connected to the car and the counterweight (counterweight) respectively. The motor drives the traction wheel to lift the car. As a vertical lifting equipment of a building, the elevator has strict requirements for safety and reliability, high transportation efficiency, accurate leveling and comfortable riding.

The car frame (hanger) is the load-bearing mechanism of the car. The load of the car (including its own weight and load) is transferred from the car frame to the traction wire rope. When the safety clamp is activated or the bottom hits the buffer, it must also withstand the reaction force caused by this; therefore, the car frame must have sufficient strength, rigidity and impact load resistance.

For the car frame (hanger) structure, it is a rectangular frame structure composed of an upper beam, a lower beam (bottom beam), columns (side beams or vertical beams), and tie rods, which bear the entire weight of the car body and stabilize vertical operation; the upper beam is located at the top of the car frame, the lower beam (bottom beam) is located at the bottom of the car frame, the columns (side beams or vertical beams) are located on both sides of the car frame, and the tie rods (pull bars) are located around the car frame and are used in pairs. For the car frame, safety performance during high-speed operation is always the first priority. Therefore, for the car body components, sufficient strength, rigidity, impact load resistance, and fatigue resistance are key factors that must be considered, and the technical requirements of the car frame need to be met through materials, structures, processing technology, installation technology, etc.

As for the column structure of the car frame, as shown in FIG3 , the column 10 (side beam or vertical beam) structural component is composed of four parts, namely, the vertical beam body 20, the safety clamp seat 30, the guide shoe seat 40, and the reinforcing plate 50. The vertical beam body 20 is an equilateral U-shaped structure. The guide shoe 60 at the front end (top) in the U-shaped groove of the vertical beam body 20, the safety clamp 70 at the back of the safety clamp seat 30, and the guide shoe 60 at the back of the guide shoe seat 40 form a discontinuous rectangular groove that runs through the entire column 10 structural component. The rectangular groove is the main carrier of the guidance and safety function of the column 10. When the passenger elevator is running at high speed, the discontinuous rectangular grooves of the columns 10 on the left and right sides of the car frame (hanger) are closely attached to the vertical guide rails of the elevator shaft frame, and the guide shoes 60 at the upper and lower ends play a guiding role. The safety clamp 70 near the lower end instantly clamps the guide rails under the action of the safety mechanism in the emergency braking state, realizing the emergency suspension braking function of the car frame. Although the current design of the column 10 structure can meet the technical requirements of passenger elevators when running at high speed, since passenger elevators run reciprocatingly at high speed, the straightness accuracy of the column 10 is required to be relatively high, so that the straightness requirements of the guide shoes 60 and the safety clamps 70 at the top and bottom of the column 10 are relatively high. During on-site installation, due to the limitations of the elevator shaft environment in the building, the installation and adjustment of the straightness is usually cumbersome and time-consuming. In addition, since the safety clamp seat 30 is connected to the lower part of the vertical beam body 20 of the column 10, and the guide shoe seat 40 is connected to the safety clamp seat 30, it is easy to cause cumulative errors, resulting in poor straightness.
