Description

Technical Field

[0001] This utility model pertains to elevator accessories, specifically relating to an elevator wire rope tensioning device. Background Technology

Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing an elevator wire rope tensioning device.

[0005] This utility model adopts the following technical solution: an elevator wire rope tensioning device, comprising a base, a first positioning seat, a second positioning seat, a telescopic assembly, a first rotating assembly, and a second rotating assembly, wherein:

[0006] The telescopic assembly includes a telescopic rod and a first sleeve, a first spring, a second spring, and a second sleeve fitted onto the telescopic rod. One end of the telescopic rod passes through both a first positioning seat and a base. The first sleeve and the second sleeve are fixedly connected to the telescopic rod. One end of the first spring abuts against the first sleeve, and the other end of the first spring abuts against the first positioning seat. One end of the second spring abuts against the second sleeve, and the other end of the second spring abuts against the base.

[0007] The first rotating assembly is rotatably connected to the first positioning seat and the second positioning seat respectively, the second rotating assembly is rotatably connected to the first positioning seat and the second positioning seat respectively, and the other end of the telescopic rod is fixedly connected to the second positioning seat.

[0008] As a preferred embodiment of the above technical solutions, the first spring is located between the first sleeve and the first positioning seat, and the second spring is located between the second sleeve and the base.

[0009] As a preferred technical solution to the above technical solutions, the telescopic rod is centrally distributed relative to the first positioning seat, the second positioning seat, and the base, and the first rotating component and the second rotating component are symmetrically distributed relative to the telescopic rod.

Detailed Implementation

[0018] This utility model discloses an elevator wire rope tensioning device. The following description, in conjunction with a preferred embodiment (Embodiment 1), refers to the accompanying drawings. Figures 1 to 4 The specific embodiments of this utility model will be further described below.

[0019] See attached diagram. Figures 1 to 4 , Figures 1 to 4 The elevator wire rope tensioning device is shown from different perspectives.

[0020] Example 1.

[0021] It should be noted that the object of the elevator wire rope tensioning device is the wire rope itself, such as... Figure 3 As shown by the red line. In other words, Figure 3 The red lines schematically indicate the possible location of the wire rope.

[0022] Preferably, the elevator wire rope tensioning device includes a base 110, a first positioning seat 120, a second positioning seat 130, a telescopic assembly 140, a first rotating assembly 150, and a second rotating assembly 160, wherein:

[0023] The telescopic assembly 140 includes a telescopic rod 141 and a first sleeve 142, a first spring 143, a second spring 144 and a second sleeve 145 sleeved on the telescopic rod 141. One end of the telescopic rod 141 passes through both the first positioning seat 120 and the base 110, so that the telescopic rod 141 can reciprocate in the vertical direction relative to the base 110 and the first positioning seat 120.

[0024] The first sleeve 142 and the second sleeve 145 are fixedly connected to the telescopic rod 141. One end of the first spring 143 abuts against the first sleeve 142, and the other end of the first spring 143 abuts against the first positioning seat 120. One end of the second spring 144 abuts against the second sleeve 145, and the other end of the second spring 144 abuts against the base 110. This allows the first spring 143 to be located between the first sleeve 142 and the first positioning seat 120, and the second spring 144 to be located between the second sleeve 145 and the base 110. Consequently, the reciprocating motion of the telescopic rod 141 in the up-down direction has a limit position (i.e., the stroke of the first spring 143 or the stroke of the second spring 144 is completely compressed, at which point the first sleeve 142 directly abuts against the first positioning seat 120, or the second sleeve 145 directly abuts against the base 110).

[0025] The first rotating assembly 150 is rotatably connected to the first positioning seat 120 and the second positioning seat 130 respectively, the second rotating assembly 160 is rotatably connected to the first positioning seat 120 and the second positioning seat 130 respectively, and the other end of the telescopic rod 141 is fixedly connected to the second positioning seat 130.

[0026] As an explanation, such as Figure 3As shown, the wire rope naturally wraps around the first rotating component 150, the second positioning seat 130 and the second rotating component 160 under its own gravity. As the wire rope moves, it drives the first rotating component 150, the second positioning seat 130 and the second rotating component 160 to move synchronously, thereby driving the telescopic component 140 to move. Because the telescopic component 140 has a limit position, the wire rope can maintain a certain buffer space (within the stroke of the first spring 143 or the second spring 144, at which time the first rotating component 150, the second positioning seat 130 and the second rotating component 160 can change their configuration relative to the first positioning seat 130). In dangerous situations such as elevator overshoot, the stroke of the first spring 143 or the stroke of the second spring 144 is completely compressed, and the first rotating component 150, the second positioning seat 130 and the second rotating component 160 no longer change their configuration relative to the first positioning seat 130. Instead, the first rotating component 150, the second positioning seat 130 and the second rotating component 160 maintain a stable configuration relative to the first positioning seat 130, thereby tensioning the wire rope.

[0027] The telescopic rod 141 is centrally distributed relative to the first positioning seat 120, the second positioning seat 130 and the base 110, and the first rotating component 150 and the second rotating component 160 are symmetrically distributed relative to the telescopic rod 141.

[0028] The first rotating assembly 150 includes a first lower support rod 151 and a first upper support rod 152. One end of the first lower support rod 151 is rotatably connected to one end of the first upper support rod 152, the other end of the first lower support rod 151 is rotatably connected to the first positioning seat 130, and the other end of the first upper support rod 152 is rotatably connected to the second positioning seat 130.

[0029] The second rotating assembly 160 includes a second lower support rod 161 and a second lower support rod 162. One end of the second lower support rod 161 is rotatably connected to one end of the second upper support rod 162, and the other end of the second lower support rod 161 is rotatably connected to the first positioning seat 130. The other end of the second upper support rod 162 is rotatably connected to the second positioning seat 130.

[0030] The first rotating assembly 150 also includes two first guard plates 153, which are respectively disposed at the rotating connection of the first lower support rod 151 and the first upper support rod 152 to prevent the wire rope from slipping off the first rotating assembly 150.

[0031] The second rotating assembly 160 also includes two second guard plates 163, which are respectively disposed at the rotating connection of the second lower support rod 161 and the second upper support rod 162 to prevent the wire rope from slipping off the second rotating assembly 160.

[0032] It is worth mentioning that the specific structure and other technical features of the base 110 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement methods of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0033] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
