Description

Technical Field

[0001] This utility model relates to a semi-compensation elevator compensation system, belonging to the field of elevator technology. Background Technology

[0002] During elevator operation, the weight of the steel wire ropes on both sides of the traction sheave changes as the elevator moves up and down, causing the torque on the traction sheave to change continuously, which affects the life of the traction machine. The design of the compensation chain can compensate for this weight change and ensure that the traction sheave can maintain a stable operating state at any position in the elevator shaft.

[0003] Traditional counterweight-side compensation chains cannot guarantee weight balance between the counterweight and the car at all positions during elevator operation. As the car height increases, the weight of the counterweight-side compensation chain gradually increases. When the car is at the top floor, the entire weight of the compensation chain is applied to the counterweight side, which generates an eccentric load on the car. This eccentric load puts pressure on the main guide rail, increasing the wear of the car guide shoes and making it difficult to calculate elevator traction conditions. Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a semi-compensation elevator compensation system.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a semi-compensated elevator compensation system, applied within an elevator shaft, comprising a car, a counterweight device, traction steel wire ropes, a compensation chain hanger, a counterweight compensation chain, and a car compensation chain; the counterweight device is located on one side of the car, and the car and counterweight device are connected by the traction steel wire ropes; the compensation chain hanger is connected and fixed to the shaft wall of the elevator shaft; multiple counterweight compensation chains and car compensation chains are provided, with one end of each counterweight compensation chain connected and fixed to the counterweight device, and the other end connected and fixed to the bottom edge of the car near the counterweight device; one end of each car compensation chain is connected and fixed to the bottom edge of the car away from the counterweight device, and the other end connected and fixed to the compensation chain hanger.

[0006] Preferably, the installation height of the compensation chain hanger is half of the elevator travel.

[0007] Preferably, the plurality of counterweight compensation chains and the plurality of car compensation chains are symmetrically arranged along the front-rear direction of the car, and the positions of the plurality of counterweight compensation chains correspond to the positions of the plurality of car compensation chains; each counterweight compensation chain forms two connection points on the car and the counterweight device, and the horizontal distance between the two connection points is greater than the maximum bending radius of the counterweight compensation chain; each car compensation chain forms two connection points on the car and the compensation chain hanger, and the horizontal distance between the two connection points is greater than the maximum bending radius of the car compensation chain; the connection points of the counterweight compensation chains on the car and the connection points of the car compensation chains on the car are symmetrically arranged.

[0008] Preferably, the unit weight of the car compensation chain is twice the unit weight of the counterweight compensation chain.

[0009] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:

[0010] 1. This utility model overcomes the shortcomings of traditional compensation chains in ensuring the weight balance of the car. By setting a car compensation chain at the bottom of the car on the side opposite to the counterweight device, the weights of the counterweight compensation chain and the car compensation chain remain equal during the car lifting process. This avoids the eccentric load on the car generated by the traditional single-sided compensation chain, reduces the pressure exerted on the main guide rail by the car due to eccentric load, significantly reduces the wear of the car guide shoes, and greatly improves the overall operating efficiency of the elevator.

[0011] 2. By fixing the end of the car compensation chain furthest from the car at halfway point of the elevator travel, the combined weight of the car compensation chain and the counterweight compensation chain is balanced with the weight of the traction steel wire rope. This ensures stable elevator operation while optimizing the calculation of elevator traction conditions.

[0012] 3. By symmetrically arranging multiple counterweight compensation chains and multiple car compensation chains along the front-to-back direction of the car, the front-to-back balance of the car is achieved. By symmetrically arranging the connection points of the counterweight compensation chains on the car and the connection points of the car compensation chains on the car, the left-to-right balance of the car is achieved, thereby improving the overall balance of the car and making the elevator run more smoothly.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0018] As attached Figure 1-2 As shown, the semi-compensated elevator compensation system of this utility model is applied in the elevator shaft 8 and includes a car 3, a counterweight device 4, a traction steel wire rope 5, a compensation chain hanger 9, a counterweight compensation chain 6, and a car compensation chain 7.

[0019] In this embodiment, the elevator shaft 8 is provided with a main guide rail 1 for the car 3 to move up and down and a secondary guide rail 2 for the counterweight device 4 to move up and down.

[0020] The counterweight device 4 is located on one side of the car 3. The car 3 and the counterweight device 4 are connected by the traction steel wire rope 5. The compensation chain hanger 9 is connected and fixed to the shaft wall of the elevator shaft 8. One end of each counterweight compensation chain 6 is connected and fixed to the counterweight device 4, and the other end is connected and fixed to the bottom edge of the car 3 on the side close to the counterweight device 4. One end of each car compensation chain 7 is connected and fixed to the bottom edge of the car 3 on the side away from the counterweight device 4, and the other end is connected and fixed to the compensation chain hanger 9.

[0021] The connection position of the car compensation chain 7 on the side away from the car 3 can be changed according to the actual situation. In this embodiment, the car compensation chain 7 is fixed on the compensation chain hanger 9. In other embodiments, the car compensation chain 7 can also be directly fixed on the hoistway wall or the main guide rail 1 support on the side of the car 3.

[0022] Compared with the traditional elevator compensation structure, this application sets a car compensation chain 7 at the bottom of the car 3 on the side opposite to the counterweight device 4. During the lifting process of the car 3, the weight of the counterweight compensation chain 6 and the car compensation chain 7 always remain equal, thereby avoiding the eccentric load force generated by the traditional single-sided compensation chain on the car 3, reducing the pressure exerted by the car 3 on the main guide rail 1 due to the eccentric load, greatly reducing the wear of the guide shoes of the car 3, and greatly improving the overall operation of the elevator.

[0023] The installation height of the compensating chain hanger 9 is half the elevator travel distance. Since the compensating chain hanger 9 is fixed at half the elevator travel distance, the car compensating chain 7 is half the length of the counterweight compensating chain 6. In order to maintain weight balance between the car compensating chain 7 and the counterweight compensating chain 6, the unit weight of the car compensating chain 7 is twice the unit weight of the counterweight compensating chain 6.

[0024] In actual operation, the installation height of the compensating chain hanger 9 can be adjusted appropriately according to the actual situation to meet the actual installation needs.

[0025] Multiple counterweight compensation chains 6 and car compensation chains 7 are provided. In this embodiment, there are two counterweight compensation chains 6 and two car compensation chains 7. However, in actual use, the number can be increased appropriately according to the load of the car 3.

[0026] Multiple counterweight compensation chains 6 and multiple car compensation chains 7 are symmetrically arranged along the front and rear direction of the car 3, and the positions of the multiple counterweight compensation chains 6 correspond to the positions of the multiple car compensation chains 7 to ensure the front and rear balance of the car 3.

[0027] Reference Appendix Figure 1 In this embodiment, the installation direction of the counterweight compensation chain 6 is defined as the left-right direction, and the direction perpendicular to the counterweight compensation chain 6 is defined as the front-back direction.

[0028] Each counterweight compensation chain 6 forms two connection points on the car 3 and the counterweight device 4, and the horizontal distance between these two connection points is greater than the maximum bending radius of the counterweight compensation chain 6; each car compensation chain 7 forms two connection points on the car 3 and the compensation chain hanger 9, and the horizontal distance between these two connection points is greater than the maximum bending radius of the car compensation chain 7; at the same time, the counterweight compensation chain 6 and the car compensation chain 7 should be as close as possible to the edge of the car 3, and not too close to the main guide rail 1, to prevent collision and entanglement with the main guide rail 1.

[0029] The connection points of the counterweight compensation chain 6 on the car 3 and the connection points of the car compensation chain 7 on the car 3 are symmetrically arranged to achieve left and right balance of the car 3.

[0030] The above are merely specific application examples of this utility model and do not constitute any limitation on the scope of protection of this utility model; all technical solutions formed by equivalent transformation or equivalent substitution fall within the scope of protection of this utility model.
