Description

Technical Field

[0001] The utility model relates to the field of elevators, in particular to an elastic supporting structure of an elevator guide rail. Background Art

[0002] When the elevator is running, the traction sheave drives the car and counterweight to move up and down along the guide rail. Due to the influence of various factors, such as the acceleration, deceleration, and load changes of the elevator, vibration and impact force will be generated. At this time, the role of the elastic support structure is to absorb and buffer the vibration and impact force through elastic elements, thereby reducing the vibration and noise transmitted to the building structure and improving the running stability and comfort of the elevator.

[0003] At present, the elastic support mechanism of the traction wheel can effectively reduce the impact force of the car. However, during the use of the traction wheel itself, it is difficult to lubricate the elevator wire rope because the elevator wire rope is located inside the narrow elevator shaft. Long-term lack of lubrication will lead to increased friction between the wire rope and the traction wheel and other components during operation, thereby accelerating the wear of the wire rope and shortening its service life. Therefore, an elastic support structure of an elevator guide rail is proposed to address the above problem. Utility Model Content

[0004] In order to make up for the deficiencies of the prior art and avoid the problem of reduced service life of elevator wire ropes, the utility model proposes an elastic supporting structure for elevator guide rails.

[0005] The utility model solves the technical problem by adopting the following technical solution: an elastic support structure of an elevator guide rail, comprising an elevator shaft, a support platform is fixedly installed at the top of the elevator shaft, a traction machine is arranged on the top of the support platform, a steel wire rope is wound and connected inside the traction machine, a driving component is arranged on the top of the traction machine, and a lubrication component is arranged on the surface of the driving component;

[0006] The driving assembly includes a supporting platform fixedly mounted on the top of the traction machine, pressure springs are fixedly mounted on the front and rear sides of the bottom end of the supporting platform, a connecting block is fixedly mounted on the bottom end of the pressure spring, an arc plate is fixedly mounted on the bottom end of the connecting block, a rotating roller is rotatably connected to the middle part of the arc plate, belts are sleeved on the surfaces of the front and rear ends of the rotating roller, an eccentric roller is rotatably connected to the inside of the connecting block, a connecting spring is fixedly mounted on the top wall of the connecting block, and a push rod is fixedly mounted on the bottom end of the connecting spring.

[0007] Preferably, a telescopic rod is fixedly connected between the middle part of the top of the connecting block and the bottom end of the supporting platform, and the telescopic rod keeps the connecting block stable during the lifting process. The bottom of the arc plate is in adaptive contact with the steel wire rope, and the rotating roller is adaptively slidably connected with the steel wire rope. When the steel wire rope is running, the rotating roller is driven to rotate by friction.

[0008] Preferably, the side of the belt away from the rotating roller is sleeved on the surface of the eccentric roller. The eccentric roller is eccentrically arranged. When the rotating roller rotates, the eccentric roller is driven by the belt to rotate eccentrically. The eccentric roller and the push rod are in adaptive contact. When the eccentric roller rotates eccentrically, it will periodically push the push rod.

[0009] Preferably, the lubrication assembly includes an oil reservoir fixedly mounted on the right side inside the arc plate, the oil reservoir is slidably connected to a slide rod inside, a push block is fixedly mounted on the bottom end of the slide rod, a one-way valve is fixedly mounted on the bottom end of the oil reservoir, a connecting plate is rotatably connected to the left side inside the arc plate, and a brush is fixedly mounted on the bottom end of the connecting plate.

[0010] Preferably, the top end of the slide rod extends above the oil reservoir, the bottom of the push block faces the wire rope, and the push rod is rotated away from the side of the eccentric roller and connected to the top end of the slide rod. The push rod pushes the slide rod downward, thereby opening the wire rope and allowing the lubricating oil to drip onto the wire rope below to lubricate it.

[0011] Preferably, one end of the brush away from the connecting plate is in adaptive contact with the steel wire rope, and the brush evenly applies the lubricating oil on the surface of the steel wire rope.

[0012] The utility model is beneficial in that:

[0013] The utility model can spray lubricating oil in the oil reservoir onto the surface of the steel wire rope periodically during the process of the steel wire rope running and pulling the car, and the brush can automatically apply the lubricating oil on the surface of the steel wire rope, so that the lubricating oil is evenly applied to the surface of the steel wire rope, thereby reducing the wear between the steel wire rope and the traction machine, thereby improving the service life of the steel wire rope; and the lubricating oil that the oil reservoir can automatically spray when the steel wire rope is running, which not only improves the utilization rate of the lubricating oil, but also does not require manual operation, thereby improving the lubrication efficiency.

The side of the belt 56 away from the rotating roller 55 is sleeved on the surface of the eccentric roller 57, and the eccentric roller 57 is eccentrically arranged. When the rotating roller 55 rotates, the eccentric roller 57 is driven to rotate eccentrically through the belt 56, and the eccentric roller 57 and the push rod 59 are in adaptive contact.
