Description

Technical Field

[0001] The utility model relates to a safety climbing device, in particular to an anti-falling safety climbing device for a wind power tower, and belongs to the technical field of wind power tower climbing construction. Background Art

[0002] In the prior art, for example, the invention with publication number 202110015906.0 discloses a climbing safety protection device for a wind turbine tower and a method for using the same. In order to solve the problem that the safety rope needs to be untied and buckled multiple times during the climbing process, which is cumbersome and risky to operate, when the staff climbs upward, they need to move the U-shaped mounting frame upward. At this time, pushing the push rod will drive the pull ring and the safety ring to move upward, thereby loosening the wire rope, and the pull rod will rotate around the rotating shaft to disengage the brake block from the limit tooth. Then, the entire U-shaped mounting frame can move upward, and the push is stopped when it moves to a preset height. Push the rod and pull the safety ring to tighten the wire rope, so that the brake block and the limit tooth will contact each other again to complete the braking. The whole process does not require the safety rope to be repeatedly hooked. When the staff climbs down, they need to move the U-shaped mounting frame downward. At this time, they only need to pull the pull ring upward. The pull ring drives the entire U-shaped mounting frame to move upward under the action of the track and the slider. At the same time, the pull rod rotates around the rotating shaft to make the brake block disengage from the limit tooth, thereby releasing the brake. The entire U-shaped mounting frame can move downward. After moving to the preset position, pulling the safety ring can realize the re-braking of the brake block. The whole process does not require the safety rope to be repeatedly hooked.

[0003] Similar to the above application, there are still some shortcomings:

[0004] During the downward movement, it is necessary to first pull the pull ring upward to release the device lock, and then pull the control device downward. Therefore, in order to ensure stable downward movement, the device needs to be continuously pulled up, which is troublesome to operate and affects the descending rate. In addition, during the descending process, the bottom end of the brake block continuously slides and rubs against the limit teeth, which will cause greater wear and affect the service life.

[0005] Therefore, a wind power tower anti-fall safety climbing device is designed to optimize the above problems. Utility Model Content

Detailed Embodiments

[0022] To make the technical solutions of the present utility model clearer and more definite for those skilled in the art, the present utility model will be further described in detail below in conjunction with the embodiments and the drawings, but the embodiments of the present utility model are not limited thereto.

[0023] Such as Figure 1-Figure 3As shown in the figure, this embodiment provides a safety climbing device for preventing falling of a wind power tower barrel, which includes a guide rail 1 vertically installed on the inner wall of the tower barrel. Guide grooves 2 are provided on both sides of the guide rail 1 along the length direction of the guide rail 1. A U-shaped plate 4 is slidably arranged on the outer side of the guide rail 1 along the length direction. Sliders 5 are fixed on the inner sides of the U-shaped plate 4, and the sliders 5 are slidably arranged inside the guide grooves 2. Rectangular slots 3 are evenly provided on the outer side of the guide rail 1 along the length direction. Pull rods 6 are rotatably installed on the outer sides of the U-shaped plate 4. A safety rope 7 is installed on the pull rod 6. A safety hook 8 is installed at the bottom end of the safety rope 7. An installation groove 9 is provided on one side of the slider 5 close to the guide rail 1. A plug 10 that cooperates with the rectangular slot 3 is slidably arranged inside the installation groove 9. A spring 12 is provided between the side of the plug 10 and the inner end of the installation groove 9. A release rope 13 is installed at one end of the plug 10 close to the spring 12. The release rope 13 slidably penetrates to the outer side of the U-shaped plate 4, and the bottom end of the release rope 13 is fixed at the bottom of the safety rope 7.

[0024] Total working principle: When the device is in use, the safety hook 8 is hung on the staff. During the climbing process of the staff, it will drive the safety rope 7 to move up or down. Since the safety rope 7 has a certain length, after rising or falling to the tension state of the safety rope 7, the release rope 13 is used to pull the plug 10 into the installation groove 9. The plug 10 is pulled out from the inside of the rectangular slot 3 to解除 the locking state of the device, and then the device is pulled to the side of the staff, and then climbing is carried out. During the climbing process, there is no need to continuously lift and drag the device.

[0025] In this embodiment, the length of the safety rope 7 is 2-3 meters, and the safety rope 7 is made of steel wire braiding.

[0026] Local working principle: The length of the safety rope 7 is fixed. Even if the staff accidentally falls, they can only fall the same length as the safety rope 7, making it safer to use.

[0027] In this embodiment, a bevel 11 is provided at the top of the plug 10 on the side close to the guide rail 1, and the horizontal length of the bevel 11 is greater than the depth of the rectangular slot 3.

[0028] Local working principle: Due to the setting of the bevel 11 at the end of the plug 10, during the upward climbing process, the bevel 11 contacts the side of the rectangular slot 3, and the plug 10 will be automatically squeezed into the installation groove 9 during the upward movement process, without dragging the release rope 13, making it more convenient to climb upward.

[0029] In this embodiment, rollers 16 are rotatably installed on the outer side edge of the bevel 11 and the end face of the plug 10 below the bevel 11, and the rollers 16 are all arranged along the width direction of the plug 10.

[0030] Local working principle: During the climbing process, due to the setting of the rotating roller 16, the traditional sliding friction mode between the inserting block 10 and the guide rail 1 is changed, and rolling friction is adopted to reduce the friction force and improve the service life of the inserting block 10.

[0031] In this embodiment, a limiting ring 14 is slidably installed inside the installation groove 9. The outer side of the limiting ring 14 is in contact with the end of the spring 12. An external screw tube 15 is installed inside the lifting pull rod 6 by threading. One end of the external screw tube 15 extends into the installation groove 9 and is in contact with the side of the limiting ring 14. The other end of the external screw tube 15 extends to the outside of the U-shaped plate 4. The releasing rope 13 passes through the inside of the limiting ring 14 and the external screw tube 15.

[0032] Local working principle: After the device has been used for a long time, the spring 12 will have a certain amount of elastic fatigue. At this time, rotate the external screw tube 15 to squeeze the limiting ring 14, and the limiting ring 14 compresses the spring 12 to ensure the elastic force of the spring 12 on the inserting block 10 during use and improve the reset effect of the inserting block 10.

[0033] In this embodiment, a threaded hole matching the external screw tube 15 is opened inside the U-shaped plate 4. A screw is installed on the top of the U-shaped plate 4 by threading, and the screw extends into the threaded hole.

[0034] Local working principle: During the process of rotating and controlling the external screw tube 15, the use of the screw can ensure the stability of the position of the external screw tube 15.

[0035] In this embodiment, the inner side surface of the end of the external screw tube 15 away from the limiting ring 14 is an arc surface, and a smooth coating is provided on the inner side of the arc surface.

[0036] Local working principle: During the pulling process of the releasing rope 13, it will rub against the inner end of the external screw tube 15, and the setting of the arc surface can reduce the wear on the releasing rope 13.

[0037] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the scope disclosed by the present invention, according to the technical solution and its concept of the present invention, makes equivalent substitutions or changes, all belong to the protection scope of the present invention.
