Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, and in particular to an automatic cleaning device for elevator wire ropes. Background Technology

[0002] Elevator wire rope is a key component of the elevator system, mainly used to support the weight of the elevator car and enable the car to move vertically within the elevator shaft.

[0003] Elevator wire ropes are typically made of multiple strands of twisted steel wires, with each strand consisting of several finer wires twisted around a central wire. These wires are generally made of high-strength carbon steel to ensure sufficient strength and durability. The structure of elevator wire ropes can be multi-stranded, commonly with 6, 8, 10, or more strands. Each strand may contain dozens or even hundreds of fine steel wires.

[0004] The existing steelmaking elevators and power plant boiler elevators are used in harsh environments, which causes the steel cables of the elevators to frequently accumulate grease and dust. The cleaning work environment is too confined, and the cleaning work itself poses a great personal safety hazard. It is also time-consuming, and the elevators cannot be guaranteed to be used until the next maintenance cycle after routine maintenance and cleaning, which makes the elevators unsafe during use.

This device can solve the problems that elevator wire ropes often get oil and dust, the working environment during cleaning is too small, the cleaning operation itself poses great personal safety hazards, is time-consuming, and the daily maintenance and cleaning cannot guarantee that the elevator can be used until the next maintenance cycle, thus creating safety hazards during elevator use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic cleaning device for elevator wire ropes, comprising an elevator connecting support, a base box, a felt cleaning trough frame, a rear brush adjusting bracket, and two brushes. The base box is fixedly connected to the upper surface of the elevator connecting support, and the felt cleaning trough frame is fixedly connected to the upper surface of the base box.

A support frame is fixedly connected to the upper surface of the felt cleaning trough frame. First sliding grooves are provided on both outer walls of the rear brush adjusting bracket. Second fixing bolts are installed on both inner walls of the support frame. Four brush fixing screws are threadedly connected to the outer wall of the rear brush fixing bracket away from the support frame.

[0007] The support frame has two slots on its upper surface, each containing a first fixing bolt. The felt cleaning tank frame has a slidably connected cleaning felt inside. The upper surface of the front brush adjusting bracket has two second sliding slots. The outer wall of the front brush adjusting bracket away from the support frame is bolted to a front brush fixing bracket. The outer wall of another brush is slidably connected to the interior of the front brush fixing bracket. Four identical brush fixing screws are threaded onto one side of the outer wall of the front brush fixing bracket. The upper surface of the cleaning felt has two third sliding slots.

The base box 2 is inverted "U" shape. Two bolt slots on the upper surface of the felt cleaning trough frame 4 correspond to the bolt slots on the upper surface of the base box 2. A rear brush fixing bracket 8 is fixedly connected to one end of the rear brush adjusting bracket 5. The outer wall of one brush 9 is slidably connected to the inside of the rear brush fixing bracket 8. The upper surface of the felt cleaning trough frame 4 is fixedly connected to the base box 2. A support frame 15 is fixedly connected, and the support frame 15 is inverted "U" shape. First sliding grooves 10 are formed on both outer walls of the rear brush adjustment bracket 5. Second fixing bolts 12 are installed on both inner walls of the support frame 15.

[0030] Furthermore, when using the device, firstly, the device is installed at a designated position on the steel wire rope of the elevator using the four fixing bolts on the elevator connecting support 1. Then, the position of the rear brush fixing frame 8 is adjusted by pushing the rear brush adjusting bracket 5, while simultaneously adjusting the brush 9. Then, the front brush adjusting bracket 6 is pushed to move towards the rear brush fixing frame 8, while simultaneously moving the brush 9 on the front brush fixing frame 7. In this way, the distance between the two brushes 9 is adjusted according to the steel wire rope so that the two brushes 9 come into contact with the steel wire rope. Then, the bolts on the first fixing bolt 3 and the second fixing bolt 12 are tightened to temporarily fix the front brush adjusting bracket 6 and the rear brush adjusting bracket 5.
