Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower anti-detachment slider technology, specifically a wind turbine tower adaptive clamping anti-detachment slider system. Background Technology

[0002] Wind turbine towers typically have ladders installed inside, with a track in the middle. When climbing the ladder, operators secure their safety belts to anti-detachment sliders via chains. The anti-detachment sliders are then slidably attached to the track. The sliders are usually designed with a structure to prevent separation from the track, thus preventing operators from accidentally falling off the ladder.

[0003] Anti-detachment sliders are usually rotatably connected to rollers. When installing the slider, the rollers are engaged with the inside of the track to facilitate the smooth movement of the slider along the track. Most sliders are additionally equipped with an adjustment mechanism to adjust the distance between the two rollers relative to each other. The adjustment mechanism first reduces the distance between the rollers to engage them in the track, and then increases the distance between the two rollers to allow the rollers to be positioned in the rolling position inside the track. The multiple operations of the adjustment mechanism make the engagement and installation of the rollers on the anti-detachment slider cumbersome. It is not conducive to the rollers being adaptively clamped and positioned on the track according to the size of the internal space, which affects the ease of installation of the anti-detachment slider. Utility Model Content

[0004] The purpose of this invention is to provide an adaptive clamping and anti-detachment slider system for wind turbine towers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A wind turbine tower adaptive clamping anti-detachment slider system includes:

[0007] A safety slider, one end of which is fixedly connected to a support base, and the other end of which is rotatably connected to a rotating shaft;

[0008] The irregularly shaped anti-detachment rod is rotatably connected to the safety slider.

[0009] The telescopic assembly consists of two components. The support base and the rotating shaft are respectively installed with the telescopic assembly at the corresponding positions. The telescopic assembly includes a sleeve, and both ends of the sleeve are slidably engaged with movable shafts. An adjusting spring is fixedly connected between the two movable shafts. A roller is rotatably mounted on one end of the movable shaft.

[0010] A pin assembly is provided at one end of the safety slider to limit and fix the position of the rotating shaft. The pin assembly includes a pin that slides and engages with the safety slider, and one end of the pin is movably inserted into the rotating shaft.

[0011] Furthermore, the outer side of the rotating shaft is provided with a round hole for inserting a pin shaft, and a knob is fixedly connected to the top of the rotating shaft.

[0012] Furthermore, both ends of the sleeve are fixed with locking blocks on their inner sides, and the outer side of the movable shaft is provided with a locking groove that slides and connects with the locking blocks.

[0013] Furthermore, the latch assembly further includes:

[0014] A limiting seat is slidably connected to a pin shaft, and the limiting seat is fixedly connected to a safety slider;

[0015] The locking spring is fixedly connected to the limit seat.

[0016] Furthermore, a wristband is fixed to one end of the pin, a columnar cavity is formed inside the pin, one end of the locking spring is fixedly connected to one end of the columnar cavity, and the limiting seat is slidably connected to the columnar cavity.

[0017] Furthermore, both ends of the safety slider are fixedly connected to a connecting shaft, and both ends of the connecting shaft are rotatably mounted with rollers.

[0018] Furthermore, one of the connecting shafts is rotatably inserted into the irregularly shaped anti-detachment rod, and a torsion spring is sleeved between the irregularly shaped anti-detachment rod and the connecting shaft.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. By arranging the safety sliders in the form of a vertical track, refer to... Figure 3 Insert the support base with two rollers into the track. Then rotate the safety slider 90 degrees so that the support base is adjusted to be parallel to the track through the telescopic component and its two bottom rollers. At this time, the telescopic component at the bottom of the support base is arranged perpendicular to the track. The elastic force of the adjusting spring inside the telescopic component drives the movable shaft on the telescopic component to slide out from the sleeve, so that the rollers at both ends of the telescopic component below the support base can adapt to the inner width of the track and abut against the inside of the track.

[0021] By turning the knob, the rotating shaft rotates 90 degrees along with the telescopic component below it, making the length direction of the telescopic component parallel to the track. At this time, the rollers at both ends of the telescopic component are arranged in the middle gap of the track. Then, the two rollers are pushed into the track by the telescopic component. Then, the knob is turned 90 degrees in the opposite direction, so that the telescopic component is arranged vertically inside the track, and the two rollers at the bottom of the rotating column can also adapt to the inner width of the track and be installed inside the track.

[0022] The telescopic component automatically moves two opposing rollers inside the track to abut against the inner side of the track, eliminating the need for manual adjustment of the spacing between the two opposing rollers and snapping them into place. This improves the ease of installation of the safety slider, allowing the two opposing rollers to automatically adapt to the inner width of the track and clamp the safety slider onto the track.

[0023] 2. A right-shaped anti-detachment rod is rotatably connected inside the safety slider via a connecting shaft. A torsion spring is sleeved between the anti-detachment rod and the connecting shaft. In the initial state, refer to... Figure 4 Under the elastic force of the torsion spring, the bottom of the irregularly shaped anti-detachment rod rotates and retracts into the internal cavity of the safety slider. When the operator accidentally falls, causing the chain to pull the top of the irregularly shaped anti-detachment rod downward momentarily, the anti-detachment rod overcomes the elastic force of the torsion spring, causing its bottom to rotate and abut against the inner side of the track. When the safety slider moves down to the anti-detachment hole position on the track, refer to... Figure 2 The bottom of the irregularly shaped anti-slip rod can be engaged with the anti-slip hole to prevent the safety slider from moving down unexpectedly. This helps prevent the safety slider from leaving the track and also helps prevent the operator from falling accidentally. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1, please refer to Figure 1 - Figure 6 In this embodiment of the present invention, a wind turbine tower adaptive clamping anti-detachment slider system includes a safety slider 100. One end of the safety slider 100 is fixedly connected to a support base 110, and the other end of the safety slider 100 is rotatably connected to a rotating shaft 120. An irregularly shaped anti-detachment rod 200 is rotatably connected inside the safety slider 100. Telescopic components 300 are installed at the bottom of both the support base 110 and the rotating shaft 120. The telescopic components 300 include sleeves 310. The support base 110 and the rotating shaft 120 are respectively fixedly connected to the corresponding sleeves 310. Both ends of the sleeves 310 are slidably engaged with movable shafts 320. An adjusting spring 330 is fixedly connected between the two movable shafts 320. A roller 321 is rotatably installed at one end of the movable shaft 320. A pin assembly 400 is slidably provided at one end of the safety slider 100. The pin assembly 400 includes a pin 410 that is slidably engaged with the safety slider 100. One end of the pin 410 is movably engaged with the rotating shaft 120.

[0033] Specifically, by installing two conventionally oppositely arranged rollers 321 at both ends of the telescopic assembly 300, after the telescopic assembly 300 is placed into the track in a suitable posture, the telescopic assembly 300 can automatically extend under the elastic force of the adjusting spring 330. This allows the rollers 321 at both ends of the telescopic assembly 300 to automatically adapt to the inner width of the track and abut against the track. As a result, the safety slider 100 is automatically clamped and installed on the outside of the track by means of the telescopic assembly 300 and the rollers 321. This eliminates the need for multiple adjustments of the distance between the two rollers 321 to install the safety slider 100 onto the track, thus improving the ease of installation of the safety slider 100.

[0034] like Figure 4 and Figure 6 As shown, in this embodiment, a circular hole is provided on the outer side of the rotating shaft 120 for the pin 410 to be inserted. When the pin 410 is inserted into the circular hole of the rotating shaft, the rotating shaft 120 is limited and fixed by the pin 410. The rotating shaft 120 cannot adjust the position of the telescopic component 300 and the roller 321 below it, so that the telescopic component 300, which is snapped into the inside of the track, always maintains a position perpendicular to the track.

[0035] In this embodiment, a knob 121 is fixedly connected to the top of the rotating shaft 120. By rotating the knob 121, the operator can make the rotating shaft 120 rotate with the telescopic component 300 below it, thereby making the telescopic component 300 rotate with the roller 321 to adjust its position.

[0036] like Figure 5 As shown, in this embodiment, both ends of the sleeve 310 are fixedly connected to the inner sides of the sleeve 310, and the outer side of the movable shaft 320 is provided with a slot 322 that is slidably connected to the slot 311. The slot 311 slides inside the slot 322 so that the movable shaft 320 can slide stably inside the sleeve 310 without separating from the sleeve 310. The movable shaft 320 can automatically extend according to the width of the track so that the roller 321 is arranged close to the inner side of the track.

[0037] like Figure 6 As shown, in this embodiment, the pin assembly 400 further includes a limiting seat 420 that is slidably connected to the pin shaft 410. The limiting seat 420 is fixedly connected to the safety slider 100. A locking spring 430 is fixedly connected to one side of the limiting seat 420. A columnar cavity is opened inside the pin shaft 410. One end of the locking spring 430 is fixedly connected to one end of the columnar cavity. The limiting seat 420 is slidably connected to the columnar cavity. A wristband 411 is fixed to one end of the pin shaft 410.

[0038] In this embodiment, Figure 6 The diagram illustrates the insertion and fixing of the pin 410 into the rotating shaft 120. When the rotating shaft 120 needs to be rotated, the hand ring 411 can be pulled outward to disengage the pin 410 from the rotating shaft 120. At this time, the limiting seat 420 slides inside the cylindrical cavity, and the locking spring 430 is in a compressed state. When the rotating column 120 returns to its initial position after rotation, the hand ring 411 is released, and the pin 410 is automatically inserted into the rotating shaft 120 under the elastic force of the locking spring 430, thereby automatically fixing the position of the rotating shaft 120.

[0039] like Figure 2 and Figure 3 As shown, in this embodiment, both ends of the safety slider 100 are fixedly connected to a connecting shaft 500, and both ends of the connecting shaft 500 are rotatably mounted with rollers 510. After multiple rollers 321 on the safety slider 100 are snapped into the inside of the track, multiple rollers 510 can be rolled on the outside of the track, which is beneficial for the safety slider 100 to move smoothly on the track.

[0040] like Figure 4As shown, in this embodiment, a connecting shaft 500 is rotatably connected to the irregular anti-detachment rod 200. A torsion spring is sleeved between the irregular anti-detachment rod 200 and the connecting shaft 500, so that in the initial state, the bottom of the irregular anti-detachment rod 200 is not connected to the anti-detachment hole on the track. Only when the irregular anti-detachment rod 200 is subjected to an unexpected downward force will the irregular anti-detachment rod 200 be inserted into the anti-detachment hole, thereby preventing the safety slider 100 from moving downward.

[0041] In this utility model, the specific structure of the track is the prior art. The spacing between the outer holes of the track is sufficient for the roller 321 to enter the track interior, and the space width inside the track is sufficient for the telescopic component 300 to adjust the position angle with the two rollers 321.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
