Description

Technical Field

[0001] The utility model relates to a compensation rope tensioning and hanging mechanism, in particular to a compensation steel wire rope tensioning and hanging device. Background Art

[0002] In high-speed elevators, the change in length of the wire rope and the accompanying cable when the elevator is running will cause a tension difference on both sides of the traction wheel, so a compensation device is needed to compensate for it. At present, the commonly used compensation device is a tension suspension device fixed in the pit. The tension suspension device includes a fixed component, a single tension wheel, and a compensation rope. One end of the compensation rope is suspended at the bottom of the car, and the other end is suspended on the counterweight frame. When the elevator is running, the change in its length is exactly opposite to the change in the length of the traction rope. However, in high-speed elevators, the weight of the compensation rope is too large, and the firmness of the existing tension suspension device cannot meet the use requirements of high-speed elevators. Therefore, it is urgent to develop a high-firmness compensation rope tension suspension device that can meet the use of high-speed elevators. Utility Model Content

[0006] In the aforementioned tensioning and suspension device for compensating wire rope, the double tension wheel assembly includes a fixed plate fixed to the inner side of each guide rail, two tension wheels distributed side by side are arranged between the two fixed plates, and two groups of symmetrically distributed steel top plates are also arranged at the upper end between the two fixed plates.

[0007] In the aforementioned tensioning and suspension device for compensating steel wire rope, the guide rail is a T-shaped guide rail.

[0008] In the aforementioned tensioning and suspension device for compensating steel wire ropes, a reinforcing rib plate connected to the steel bottom plate is provided on the outer side of the support plate.

[0009] Compared with the prior art, the utility model is composed of a steel bottom plate connected to the pit floor via expansion bolts, support plates arranged at both ends above the steel bottom plate, guide rails arranged inside the support plate, a double tensioning wheel assembly and a channel steel. Through the mutual cooperation between the above structures, the structural strength and firmness of the overall tensioning suspension device can be effectively improved to meet the use requirements of high-speed elevators. In summary, the utility model has the characteristics of high firmness. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0013] Embodiment. A tensioning suspension device for compensating steel wire rope is constructed as follows Figure 1 As shown, it includes a steel base plate 1, support plates 2 are provided at both ends above the steel base plate 1, guide rails 3 are provided on the inner side of the support plate 2, a double tensioner assembly 4 is provided between the two guide rails 3, and a channel steel 5 is provided on the upper part between the two guide rails 3; the steel base plate 1 is connected to the pit ground through expansion bolts 6.

[0014] The double tensioner assembly 4 includes a fixing plate 401 fixed to the inner side of each guide rail 3 , two tensioners 402 arranged side by side are arranged between the two fixing plates 401 , and two groups of symmetrically distributed steel top plates 403 are also arranged at the upper end between the two fixing plates 401 .

[0015] The guide rail 3 is a T-shaped guide rail.

[0016] A reinforcing rib plate 7 connected to the steel bottom plate 1 is disposed on the outer side of the support plate 2 .

[0017] The guide rail is connected to the fixed plate via clamps, guide shoes and other components.

[0018] A compensation rope limiter is provided at the vertical position of the outgoing line above the outer side of the tensioner. A compensation rope anti-movement block is provided on the outer side of the tensioner.

[0019] There are two channel steels, which are respectively located on both sides of the raised portion of the T-shaped structural guide rail.

[0020] The steel top plate is connected to the fixing plate via L-shaped connectors and bolts.
