Description

Technical Field

[0001] The utility model relates to the field of electric power construction safety equipment, in particular to a magnetic suction type safety rope fixing bracket. Background Art

[0002] When carrying out power construction in a substation, it is often necessary to climb onto the transformer box for high-altitude operations. For the safety of the operators, the operators need to wear safety ropes when performing operations. However, there is no suitable place above the transformer box to bind the safety ropes. Therefore, it is necessary to install a safety rope fixing bracket. Most of the existing safety rope fixing brackets are fixed to the edge of the transformer box by buckles. For example, a safety rope fixing bracket with patent number 2023206164404 can be clamped by a fixed seat and a movable plate to achieve the purpose of fixing. However, when working on the transformer box, it is necessary to synchronously change the position of the fixed bracket according to the different working positions, which is very inconvenient for the operators, and disassembly and assembly also requires time and effort.

[0005] The magnetic attraction fixing device includes a fixing sleeve, a support rod sleeve, a magnet mounting box, a magnet and a push rod. The support rod sleeve is rotatably connected in the fixing sleeve, and the magnet mounting box is fixed in the fixing sleeve. The magnet mounting box is a hollow box body. Slide grooves are arranged around the inner wall of the magnet mounting box. The magnet is located in the slide groove and slides. A round hole is arranged on the top of the magnet mounting box, and one end of the push rod passes through the round hole and is fixedly connected to the upper end of the magnet.

[0006] Preferably, the bottom of the magnet mounting box is flush with the bottom of the fixing sleeve.

[0007] Preferably, a handle fixing seat is provided on one side of the top of the magnet mounting box, a handle is rotatably connected to the handle fixing seat, one end of the handle is rotatably connected to the handle fixing seat, and the middle of the handle is fixedly connected to the top of the push rod.

[0008] Preferably, a metal block is provided on the top inner side of the magnet mounting box.

[0009] Preferably, a positioning sleeve is arranged in the circular hole, an upper positioning groove and a lower positioning groove are arranged on the inner wall of the positioning sleeve, and a positioning spring piece is arranged on the outer periphery of the push rod.

[0010] The beneficial effects of the utility model are:

[0011] 1. By setting a connection plate, a fixing ring is set on the connection plate, and the bottom is supported by multiple support rods. The bottom of the support rod is fixed to the middle of the transformer box by a magnetic fixing device. When the operator is working, there is no need to frequently change the fixed position of the fixed bracket, which saves time and cost.

[0012] 2. By setting a metal block on the top of the inner side of the magnet installation box, the magnet can be adsorbed to the metal block when not working, avoiding the problem that the bottom of the magnet installation box 2-3 is always magnetic and inconvenient to carry.

[0013] 3. By setting a positioning sleeve, setting upper and lower positioning grooves on the inner wall of the positioning sleeve, and setting a positioning spring sheet on the outer periphery of the push rod, the positioning spring sheet can be located in the upper positioning groove or the lower positioning groove by pushing the push rod to prevent the magnet from moving freely up and down.
