Description

Technical Field

[0001] The utility model relates to the technical field of aerial work, in particular to a steel wire rope fixing device for aerial work. Background Art

[0002] In aerial work, it is often necessary to suspend and fix the wire rope along a column or plane, such as the traction rope of a wind turbine tower cleaning device, the wire rope of a building exterior wall construction and maintenance equipment, etc. There are currently a variety of wire rope fastening devices, such as the patent with application number 202320960839.4, which discloses an improved wire rope fastening device, including a vertical plate, a pull rod and a mounting member. The vertical plate can be supported on the ground, and at least two limit portions are provided at intervals along its length direction, and the limit portions are close to the bottom of the vertical plate. The wire rope can slide through all the limit portions in sequence, and the pull rod includes a rod body and a connecting portion for connecting to the wire rope; a mounting member is provided between every two adjacent limit portions on the vertical plate, and the mounting member is used to connect and lock the rod body to the vertical plate.

[0003] The above patent has a simple structure and is easy to operate, but the fixation of the device itself is not reliable, especially when it comes to the fixation of the suspension wire rope during high-altitude operations. Due to the limitations of the working environment, the device itself is not easy to be fixed. The looseness of the device will cause the suspension wire rope to loosen, creating a safety hazard. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a steel wire rope fixing device for aerial work, which effectively solves the problem that the existing fixing device itself is not reliable, especially it is not easy to be fixed during aerial work, resulting in loosening of the suspended steel wire rope.

[0005] The utility model is realized through the following technical solutions:

[0006] Provided is a high-altitude work wire rope fixing device, including a vertical plate, a fixed pulley is rotatably installed on the lower part of one side of the vertical plate through a mounting frame, the vertical plate is vertically connected to a side plate on the upper part of the side plate, a through hole is opened on the side plate, and a threaded pull rod is horizontally penetrated in the through hole, a locking nut is threadedly connected to the threaded end of the threaded pull rod on one side of the side plate, and a through hole is opened on the other side of the side plate along a direction perpendicular to the axis of the threaded pull rod. One end of the wire rope passes around the fixed pulley downward and then passes through the through hole upward to penetrate the threaded pull rod and is tightened and fixed by rotating the locking nut.

[0007] Furthermore, a positioning groove having the same width as the vertical plate and used for cooperating with the flat sling is formed on one side plate surface of the vertical plate between the side plate and the fixed pulley.

[0008] The concave positioning plane in the positioning groove is used to cooperate with the flat sling. The flat sling can tie the vertical plate to high-altitude fixing parts such as wind power towers and building pillars. The concave design of the positioning plane enables the flat sling to not only have vertical pressure on the vertical plate, but also provide thrust to prevent the vertical plate from sliding up and down when the vertical plate tends to slide up and down.

[0009] Furthermore, an anti-slip layer is provided on the other side of the vertical plate.

[0010] By providing an anti-skid layer on the other side of the vertical plate, the friction of the vertical plate to the wind power tower or the building surface can be increased, making the binding of the flat sling to the vertical plate more stable.

[0011] Beneficial effects of the utility model:

[0012] The utility model is provided with a positioning groove on the vertical plate, and the concave positioning plane in the positioning groove can cooperate with the flat sling to tie the vertical plate to high-altitude fixing parts such as wind power towers and building pillars. The concave design of the positioning plane enables the flat sling to exert not only vertical pressure on the vertical plate, but also provide thrust to prevent the vertical plate from sliding up and down when the vertical plate tends to slide up and down, thereby reliably fixing the device and ensuring that the suspended wire rope will not be loose.

[0018] In order to clearly illustrate the technical features of this solution, this solution is described below through a specific implementation method.

[0019] like Figure 1-Figure 4 As shown, a high-altitude work wire rope fixing device includes a vertical plate 1, and a fixed pulley 3 is rotatably installed on the lower part of the vertical plate 1 on one side of the plate surface through a mounting frame 10. The fixed pulley 3 is used to change the direction of the hanging wire rope 9. After passing around the fixed pulley 3, the end of the hanging wire rope 9 faces upward.

[0020] The vertical plate 1 is vertically connected to the side plate 2 at the upper part of the side plate surface. A through hole 8 is provided on the side plate 2, and a threaded tie rod 4 is horizontally penetrated in the through hole 8. The diameter of the through hole 8 is slightly larger than that of the threaded tie rod 4, and the two are slidably connected. The threaded end of the threaded tie rod 4 on one side of the side plate is threadedly connected with a locking nut 5. The threaded tie rod 4 is provided with a through hole 7 on the other side of the side plate 2 in a direction perpendicular to the axis of the threaded tie rod 4, through which the end of the suspension wire rope 9 can pass. One end of the wire rope 9 passes downward around the fixed pulley 3 and then passes upward through the through hole 7 through the threaded tie rod 4 and is pressed and fixed by rotating the locking nut 5. The locking nut 5 is located on the outside of the side plate 2 and can be threadedly engaged with the threaded tie rod 4. After the end of the suspension wire rope 9 passes through the through hole 7 of the threaded tie rod 4, the locking nut 5 is rotated clockwise to make the side of the threaded tie rod 4 continuously approach the side plate 2 along the axial direction until the threaded tie rod 4 cooperates with the side plate 2 to press the end of the suspension wire rope 9.

[0021] A positioning groove having the same width as the vertical board 1 and used for matching with the flat sling is formed on one side of the vertical board 1 between the side board and the fixed pulley 3. An anti-skid layer is provided on the other side of the vertical board 1.

[0022] When using the device, first use a flat sling to bind the vertical plate 1 to high-altitude fixing parts such as wind power towers and building pillars. When binding, the flat sling should be matched with the positioning plane 6 of the vertical plate 1 so that the flat sling can vertically press the vertical plate 1. At the same time, when the vertical plate 1 has a tendency to slide up and down, it can also provide thrust to ensure the reliable fixation of the vertical plate 1. Subsequently, after the suspension wire rope 9 passes around the fixed pulley 3, the end of the suspension wire rope is passed through the transverse hole 7 of the spiral pull rod 4, and then the locking nut 5 is turned clockwise to make the opening side of the spiral pull rod 4 continuously approach the side plate 2 axially until the spiral pull rod 4 cooperates with the side plate 2 to press the end of the suspension wire rope 9. The device is installed. When the high-altitude operation is completed, the locking nut 5 is turned counterclockwise to loosen the end of the suspension wire rope 9, and the suspension wire rope 9 is withdrawn from the transverse hole 7 of the spiral pull rod 4. Finally, the flat sling binding the vertical plate 1 is untied to complete the disassembly of the device.
