Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a novel compensation chain guiding device for high-speed elevators. Background Technique

[0002] As a vertical transportation tool symbolizing modern material civilization, the production capacity and ownership of elevators are important symbols of a country's modernization level; in recent years, with the increasing improvement of people's living standards and the accelerating urban development, small high-rise, high-rise residential buildings and high-rise commercial and residential buildings have emerged continuously, and the demand for elevators has also increased day by day; with the development of high-rise buildings, elevators show a trend of high speed and high-rise stations.

[0003] When the elevator is running at high speed or at high-rise stations, the weight of the traction steel wire ropes will be lifted along with the car or the counterweight, which will in turn cause the weight on the car side or the counterweight side to become larger, affecting the balance of the elevator. To solve this problem, when the elevator is running at high speed or at high-rise stations, a compensation chain needs to be set at the bottom of the car and the bottom of the counterweight. In the current elevator industry, the traditional compensation chain guiding device is as follows: the guiding device is fixed on the shaft wall through expansion bolts;

[0004] The following problems will occur in this solution:

[0005] 1. When the elevator is running at high speed, the compensation chain used will inevitably jump and collide, seriously affecting the comfort and safety of the elevator operation;

[0006] 2. Generally, high-speed elevators have a very high lifting height, and the elevator steel wire ropes are very long. After the elevator runs for a period of time, the compensation chain will get closer and closer to the bottom pit floor due to the elongation of the elevator steel wire ropes. At this time, it is necessary to shorten the compensation chain, and the operation is extremely inconvenient.

[0007] To solve the above problems, the present application discloses a novel compensation chain guiding device for high-speed elevators. Content of the Utility Model

The compression spring is sleeved outside the vertical part of the T-shaped column between the spring insert block and the top wall of the hollow column. The axle of the tensioning wheel passes through the horizontal part of the T-shaped column.

[0017] Further preferably, a U-shaped plate member is welded to the bottom of the hollow column, and the U-shaped plate member is fixed to the base by bolts.

[0018] Further preferably, both adjusting brackets include a cross beam and a Z-shaped connecting member. The cross beam is arranged along the first direction outside the two T-shaped columns on the same side and the axles of the two tensioning wheels are connected thereto. The Z-shaped connecting member is fixed to the cross beam by bolts in a state of being rotated 90°. The two ends of the axle of the guide wheel are respectively connected between the Z-shaped connecting members of the two adjusting brackets.

[0019] Further preferably, first thread portions are formed on the surfaces of both ends of the axle of the tensioning wheel. The axle of the tensioning wheel extends through the cross beam and is screwed with nuts to be connected to the horizontal part of the T-shaped column.

[0031] Embodiment

[0032] To solve the problems existing in the use of the high-speed elevator compensating chain guiding device in the prior art, as shown in Figure 1 the present application discloses a novel high-speed elevator compensating chain guiding device, including: base 10;

[0033] Two elastic support components 20 are respectively arranged on both sides of the base 10 in the first direction;

[0034] Two tensioning wheels 30 are respectively connected to the two elastic support components 20;

[0035] Two adjusting brackets 40 are respectively connected to the two elastic support components 20;

[0036] A guide wheel 50 is connected to the middle of the two adjusting brackets 40;

[0037] A compensation chain 60 is wound between the two tensioning wheels 30 above the guide wheel 50.

[0038] Reference Figure 2 And Figure 3 As shown, in this embodiment, the elastic support component 20 of the present application includes two elastic support columns 21. The two elastic support columns 21 are arranged side by side on the base 10 along the second direction, and the tensioning wheel 30 is connected between the two elastic support columns 21. Specifically, each elastic support column 21 of the present application respectively includes a hollow column 211, a T-shaped column 212, a compression spring 213 and a spring insert block 214. The hollow column 211 is fixed on the base 10. The vertical part of the T-shaped column 212 is inserted into the hollow column 211. The spring insert block 214 is sleeved under the vertical part of the T-shaped column 212. The compression spring 213 is sleeved outside the vertical part of the T-shaped column 212 between the spring insert block 214 and the top wall of the hollow column 211. The axle of the tensioning wheel 30 is arranged through the horizontal part of the T-shaped column 212. During the operation of the elevator, the compensation chain 60 is guided by the two tensioning wheels 30. By adjusting the compression amount of the compression spring 213 of the two elastic support components 20, the compensation chain 60 can always be kept in a tensioned state.

[0039] Specifically, referring to Figure 1 And Figure 2 As shown, a U-shaped plate member 70 is welded to the bottom of the hollow column 211 of the present application. The U-shaped plate member 70 is fixed to the base 10 by bolts 80. In this way, the disassembly and assembly of the hollow column 211 and the base 10 can be facilitated.

[0040] Reference Figure 2As shown, in this embodiment, both adjusting brackets 40 include a cross beam 41 and a Z-shaped connecting member 42. The cross beam 41 is arranged along the first direction outside the two T-shaped columns 212 on the same side, and the axles of the two tensioning wheels 30 are connected thereto. The Z-shaped connecting member 42 is fixed to the cross beam 41 by bolts 80 in a state of being rotated 90°. The two ends of the axle of the guide wheel 50 are respectively connected between the Z-shaped connecting members 42 of the two adjusting brackets 40. During the operation of the elevator, when the compensation chain 60 touches the ground due to the elongation of the steel wire rope, the height position of the adjusting bracket 40 can be adjusted to tighten the compensation chain 60, and the operation is extremely convenient.

[0041] The following is the fixing method of the two tensioning wheels 30 and the guide wheel 50:

[0042] Refer to Figure 2 As shown, first threaded portions (not shown) are formed on the surfaces of both ends of the axle of the tensioning wheel 30. The axle of the tensioning wheel 30 extends through the cross beam 41 and is screwed with a nut 90 to be connected to the transverse portion of the T-shaped column 212. Based on this method, the tensioning wheel 30, the T-shaped column 212 and the cross beam 41 can be quickly installed, the operation is relatively convenient, and the labor intensity of the operator can be reduced.

[0043] Refer to Figure 2 As shown, second threaded portions (not shown) are respectively formed on the surfaces of both ends of the axle of the guide wheel 50. The axle of the guide wheel 50 passes through the Z-shaped connecting members 42 of the two adjusting brackets 40 and is screwed with a nut 90 on the second threaded portion to be connected to the Z-shaped connecting member 42. Based on this method, the guide wheel 50 and the two Z-shaped connecting members 42 can be quickly installed, the operation is relatively convenient, and the labor intensity of the operator can also be reduced.
