Description

Technical Field

[0001] The utility model relates to the technical field of elevator counterweights, in particular to a high-strength shock-absorbing elevator counterweight frame. Background Art

[0002] The elevator counterweight is a device that keeps the weight of the car balanced with the effective load to reduce energy consumption and motor power loss. In addition, on a winch with a rope drive wheel, the counterweight can maintain the required stress ratio between the car and the rope branch on one side of the counterweight.

[0003] When the existing elevator counterweight frame is installed and used, it will continuously rise and fall as the elevator runs. After a long period of operation, the internal counterweight will generate vibration and noise due to collision, which will not only affect the users, but also reduce the service life of the counterweight frame. In addition, the guide shoes of the counterweight frame will also vibrate due to misfit when sliding on the track. In addition, after being used for too long, scratches will be generated due to continuous contact, which reduces the service life and brings certain adverse effects to people's use process. In order to solve the shortcomings of the existing technology, we propose a high-strength shock-absorbing elevator counterweight frame. Utility Model Content

DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] Embodiment 1, as Figure 1-4 As shown, a high-strength shock-absorbing elevator counterweight frame includes a counterweight frame 1, which is connected to the bottom of the elevator car by installing a traction wire rope on the side of the traction disc 3, and then installing a compensation chain on the compensation device 13 through the compensation connecting hole 14, and then opening the installation cover 17 on the upper end of the two groups of lubricators 16, and adding lubricating liquid into the lubricator 16. During normal operation, due to the squeezing of the pressure plate 6 by the pressure rod 4, the multiple groups of concrete counterweight blocks 7 no longer collide with each other, and then the pressure rod 4 is limited by the limit nut 5, so that the pressure plate 6 only squeezes the multiple groups of concrete counterweight blocks 7 below, thereby reducing the vibration and noise generated.

[0025] Embodiment 2, as Figure 1-4 As shown, a high-strength shock-absorbing elevator counterweight frame is provided with an upper guide shoe 15 and an auxiliary guide shoe 22 on the left and right sides of the counterweight frame 1. The counterweight frame slides on the elevator guide rail through the upper guide shoe 15 and the auxiliary guide shoe 22, and cooperates with the extrusion plate 19 provided on the inner side of the upper guide shoe 15 and the buffer plate 23 provided on the inner side of the auxiliary guide shoe 22. The right sides of the two are respectively provided with a first fixing bolt 12 and a spring 24, and the extrusion plate 19 and the buffer plate 23 are respectively made to be close to the elevator guide rail through the elastic force. In this way, the upper guide shoe 15 and the auxiliary guide shoe 22 will not have a gap between them and the elevator guide rail, which may cause vibration and noise due to shaking and collision, and the spring telescopic extrusion tube 20 provided on the inner side of the extrusion plate 19 will squeeze the lubricating fluid inside the lubricator 16 out through the lubricating oil port 21 due to the extrusion between the elevator guide rail, so that the lubricating fluid will remain on the elevator guide rail, so that the service life of the elevator guide rail and the guide shoe will not be easily reduced due to scratches.

[0026] How it works

[0027] It should be noted that the utility model is a high-strength shock-absorbing elevator counterweight frame. When in use, a traction wire rope is installed on the side of the traction disc 3, and then a compensation chain is installed on the compensation device 13 through the compensation connection hole 14, which is connected to the bottom of the elevator car. Then, the installation cover 17 at the upper end of the two sets of lubricators 16 is opened, and lubricating liquid is added to the lubricator 16. During normal operation, due to the squeezing of the pressure plate 6 by the pressure rod 4, there is no longer any collision between the multiple groups of concrete counterweight blocks 7. Then, the pressure rod 4 is limited by the limit nut 5, so that the pressure plate 6 only squeezes the multiple groups of concrete counterweight blocks 7 below, thereby reducing the vibration and noise generated. The upper guide shoe 15 and the auxiliary guide shoe 22 are provided on the left and right sides of the counterweight frame 1. The counterweight frame is provided with an upper guide shoe 15 and an auxiliary guide shoe 22. Sliding on the elevator guide rail, in conjunction with the extrusion plate 19 arranged on the inner side of the upper guide shoe 15 and the buffer plate 23 arranged on the inner side of the auxiliary guide shoe 22, a first fixing bolt 12 and a spring 24 are respectively arranged on the right side of both, and the extrusion plate 19 and the buffer plate 23 are respectively made to be close to the elevator guide rail through the elastic force, so that the upper guide shoe 15 and the auxiliary guide shoe 22 will not have a gap with the elevator guide rail, which may cause vibration and noise due to shaking and collision, and the spring telescopic extrusion tube 20 arranged on the inner side of the extrusion plate 19 will squeeze the lubricating fluid inside the lubricator 16 out through the lubricating oil port 21 due to the extrusion between the elevator guide rail, so that the lubricating fluid will remain on the elevator guide rail, so that the elevator guide rail and the guide shoe will not easily be scratched and the service life will be reduced.
