Description

Technical Field

[0001] The invention relates to the field of power supply safety devices, and in particular to a detachable anti-falling sliding block and a use method thereof. Background Art

[0002] Due to the large increase in ultra-high voltage transmission lines in my country, the inspection and maintenance work of the operation and maintenance units is becoming more and more frequent. Therefore, in order to ensure the safety of the operators, most of the newly built (ultra) ultra-high voltage line towers are equipped with anti-fall slide rails, and the anti-fall sliders that match them are promoted and applied. The traditional anti-fall slider is inserted upward from the anti-fall slide rail at the bottom of the tower. If the tower climber accidentally falls, the safety protection rope of the anti-fall slider will pull the tail pull ring of the locking thimble downward under the force of the human body. At this time, the head of the locking thimble will protrude inward and hold up the plane of the tower slide rail (such as Figure 1 As shown in the figure), it plays a buffering and decelerating effect, and then locks on the tower slide rail.

[0003] However, the slide rail is assembled simultaneously with the high-voltage tower body, and the assembly method is segmented assembly. After long-term exposure to the outdoor air and the invasion of rain, snow, ice and strong winds, the splicing position will be deformed, bulged, rusted, etc. due to uneven force, thermal expansion and contraction. This causes the anti-fall slider to get stuck and the splicing position to be excessively discontinuous during the tower climbing process, affecting the progress of maintenance work and reducing work efficiency. In addition, the labor intensity, time and risk of operators using tools to repair the track on site are high. Therefore, the development of a detachable anti-fall slider suitable for (ultra) UHV power towers is of great significance to ensure the safety of operators;

[0004] Therefore, it is necessary to design a detachable anti-falling sliding block and a method for using the same.

[0005] Among the existing patents, the closest prior art is the patent with application number CN201521055804.8, entitled "A drag-reducing anti-falling slider for descending a tower", which discloses an anti-falling slider body (1) and a lock (2), characterized in that it also includes: a drag-reducing device, the aforementioned drag-reducing device includes: a spring pressure plate (3) and a spring (4), the spring pressure plate (3) is located at the upper end of the lock (2) and is fixedly connected to the lock (2), the two ends of the spring (4) are respectively connected to the spring pressure plate (3) and the anti-falling slider body (1), and the spring (4) is in a naturally extended state. The benefit of the utility model is that: when the maintenance personnel descend the tower normally, the drag-reducing device can lift the lock to prevent the anti-falling slider body from being accidentally stuck with the slide rail, thereby ensuring smooth descent; when the maintenance personnel accidentally fall, the anti-falling slider body can jam the slide rail to protect the personnel. This patent uses a spring pressure plate, and the spring is relatively easy to damage and fail. It is unsafe and impractical to use elastic components for very important safety protection.

[0006] There is also a patent with application number CN202022711098.5, named as a safety component for preventing falling in wind turbine tower. The patent discloses a safety component body, the safety component body includes a stress releaser, one end of the stress releaser is fixedly connected to the anti-falling slider arranged on the slide rail in the tower, the other end of the stress releaser is connected to one end of the elastic connector, the other end of the elastic connector is connected to a connecting ring with an opening and closing structure through a connecting chain, the connecting ring is used to connect to the safety ring on the operator, and the two ends of the connecting chain are connected by a connecting buckle with an opening and closing structure; the structural design of the stress releaser in the patent safety component body can prevent the connection chain from twisting and the connection ring and the safety ring on the operator, ensure the safety and comfort of use, and provide a safety guarantee for the operator when transferring from the top of the ladder to the tower platform; however, due to the use of elastic components, there is also a disadvantage of easy failure. Summary of the invention

[0007] The technical problem to be solved by the present invention is to provide a detachable anti-falling slider and a method of using the same, which can be flexibly disassembled into two parts, effectively dealing with obstacles to climbing towers caused by deformation of pole towers, misalignment of slide rails, and corrosion of interfaces. The risk of falling caused by manually assisting in dragging the slider and repairing the slide rails in order to allow the slider to smoothly pass through the high-resistance slide rail area is reduced, thereby effectively reducing the time consumption of climbing the tower and improving the safety and timeliness of line maintenance.

[0016] Furthermore, a protrusion is provided in the sink groove; an anti-slip ring is inserted on the bolt head of the slide rod bolt; when the slide rod bolt is tightened, the anti-slip ring is sleeved on the protrusion.

[0017] Furthermore, two drag-reducing wheels are provided on a side of the right load-bearing body away from the left load-bearing body;

[0018] Two drag-reducing wheels are arranged on a side of the left load-bearing body away from the right load-bearing body;

[0019] The four drag-reducing wheels all roll in the anti-falling slide rail.

[0020] A method for using a detachable anti-falling slider comprises the following steps:

[0022] S2, when the anti-falling sliding block is stuck and cannot move on the anti-falling sliding rail, pull up the anti-slip ring from the protrusion, unscrew the sliding rod bolt, remove the right load-bearing body along the guide rail, and then remove the device, pass over the stuck part, and reinstall it.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. Through the provided guide rails and slide grooves, the right load-bearing body and the left load-bearing body can slide, which is convenient for positioning, installation and disassembly;

[0025] 2. By setting up the semi-circular arc groove, it is avoided that the strength of the guide rail is reduced when the entire hole passes through the guide rail, and the safety hazard can be eliminated.
