Description

Technical Field

[0001] The utility model relates to an elevator maintenance device, in particular to a traction machine brake maintenance platform. Background Art

[0002] As a special equipment, daily maintenance and inspection are necessary for elevators. The elevator maintenance work needs to be carried out by maintenance personnel entering the elevator shaft. For the inspection of the traction motor brake, the maintenance personnel need to further reach the top of the elevator car, and the car needs to stop at the corresponding maintenance floor. The stopping position of the elevator is relatively fixed. The traction motor brake is usually at a certain distance from the car. The maintenance personnel need to partially stick their bodies out of the car to contact the brake, which poses certain safety hazards. Therefore, it is necessary to design a safe platform for maintenance. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a traction machine brake maintenance platform.

[0004] The technical solution adopted by the utility model to solve the above-mentioned problem is: the maintenance platform includes a guardrail device, a basic fixing device and a stepping device. The guardrail device forms a rigid protective structure with fences on four sides, and has a supporting pedal at the bottom. A basic fixing device is fixedly arranged at the bottom of the guardrail device, and the basic fixing device is fixedly installed with the upper crossbeam of the car frame. A stepping device is arranged corresponding to the bottom of the guardrail device and fixed to the basic fixing device. The stepping device has a step structure and leads to the guardrail device. This device is fixed to the upper crossbeam of the elevator car frame, which can effectively increase the basic height of the maintenance platform and be closer to the position to be inspected. The guardrail structure can protect the body from losing the center of gravity. The basic fixing device is the main fixing structure, and the connection is safe and reliable. The stepping device has steps, which can easily enter the guardrail device.

[0005] Furthermore, the guardrail device includes upright posts with rectangular distribution, crossbars are transversely connected between the upright posts, the crossbars are arranged at least at three different height positions, and a support pedal is fixed at the bottom end of the upright post, and the support pedal forms a working platform surface. The guardrail device is formed by mutually fixing upright posts and crossbars, has a reliable protection height and protection distance, and the support pedal at the bottom has a good support effect, the working platform is stable, and has a good sense of security.

[0006] Furthermore, an emergency stop switch is installed on the guardrail device, and the emergency stop switch is connected to the control circuit of the elevator. The emergency stop switch is arranged near the guardrail device. When entering for maintenance, pressing the emergency stop switch can shut down the operation of the elevator and make the elevator's safety clamp effective, thereby improving the safety during maintenance.

[0007] Furthermore, the foundation fixing device includes two horizontally arranged channel steels, which are arranged in parallel, one end of which is fixed to the guardrail device, and the other end of which is fixed to the upper crossbeam. The foundation fixing device is a basic structure, and is assembled and installed with channel steels with good rigidity, so the structure has good safety and reliability.

[0008] Furthermore, the stepping device comprises a base frame and a step pedal, wherein the base frame is two layers of steel materials with a step cross section, and the step pedal is horizontally fixed on the base frame. The stepping device has a step structure and a step pedal, is easy to use, and saves time and effort.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on an elevator maintenance device, which is mainly used to repair the brake of the traction machine, and can also repair the counterweight speed limiter in a similar position, and can provide a safe and reliable platform for maintenance personnel, thereby improving work safety.
