Technical Field
[0001] The utility model relates to the technical field of fixing devices, in particular to a safety belt hanging device for the top of a transformer. Background Art
[0002] A transformer is a device that uses the principle of electromagnetic induction to change the AC voltage. Its main components are the primary coil, secondary coil, and iron core (magnetic core). In electrical equipment and radio circuits, it is commonly used for stepping up or down voltages, impedance matching, safety isolation, etc.
[0003] In the prior art, the height of transformers above 110 kV generally exceeds two meters. Therefore, according to safety regulations, workers performing high-altitude operations must wear and correctly use safety belts to ensure safety. However, due to the influence of the layout of transformer components and the installation operation surface, when workers perform operations on the top of the transformer, there is no reliable and effective safety hanging point to fix the safety belt, which may affect the safety of workers on the top of the transformer. Content of the Utility Model
[0004] The utility model aims at the deficiencies of the prior art and provides a safety belt hanging device for the top of a transformer, which can not only improve the safety of workers on the top of the transformer, prevent workers from falling off the transformer, but also limit the safety hook on the safety belt, prevent the safety hook from moving horizontally, and improve the stability of the safety belt during the use of the device.
[0005] The utility model is realized by the following technical solutions: A safety belt hanging device for the top of a transformer is provided. A U-shaped rod is fixedly installed on the top of the transformer. An arc-shaped rod is fixedly connected to the top of the U-shaped rod. The openings of the U-shaped rod and the arc-shaped rod both face downward. The vertical distance between the arc-shaped rod and the U-shaped rod forms a safety belt fixing space.
[0006] During the use of the utility model, a U-shaped rod is fixedly installed on the top of the transformer, and an arc-shaped rod is fixedly connected to the top of the U-shaped rod. The openings of the U-shaped rod and the arc-shaped rod both face downward. The vertical distance between the top of the arc of the arc-shaped rod and the U-shaped rod forms a safety belt fixing space. When the device is in use, a worker climbing to the top of the transformer moves and presses the safety hook on the safety belt to make the safety hook penetrate into the safety belt fixing space, and then releases the safety hook, so that the safety hook is hung on the arc-shaped rod or the U-shaped rod, thereby connecting the worker to the arc-shaped rod or the U-shaped rod through the safety belt. In this way, it can not only improve the safety of workers on the top of the transformer, prevent workers from falling off the transformer, but also limit the safety hook on the safety belt, prevent the safety hook from moving horizontally, and improve the stability of the safety belt during the use of the device.
[0007] Preferably, a base fixedly connected to the top of the transformer is installed at the bottom of the U-shaped rod. By installing a base fixedly connected to the top of the transformer at the bottom of the U-shaped rod, the base can facilitate the staff to fix the U-shaped rod on the transformer.
[0008] Preferably, three U-shaped rods are arranged at the top of the transformer, and the three U-shaped rods are equidistantly distributed along the length extension direction of the transformer. By arranging three U-shaped rods at the top of the transformer and the three U-shaped rods being equidistantly distributed along the length extension direction of the transformer, the safety of the staff when moving on the top of the transformer can be ensured.
[0009] Preferably, a first flange is fixedly connected to the bottom of the U-shaped rod, a second flange is fixedly connected to the top of the base, and the first flange and the second flange are fixedly connected by a threaded rod. By fixedly connecting a first flange to the bottom of the U-shaped rod, fixedly connecting a second flange to the top of the base, and fixedly connecting the first flange and the second flange by a threaded rod, by rotating the threaded rod to disengage it from the first flange and the second flange, the first flange and the second flange are no longer fixedly connected, so as to facilitate the staff to replace the arc-shaped rod or the U-shaped rod when they are corroded or damaged.
[0010] Preferably, the vertical height of the U-shaped rod is set between 1.1 m and 1.3 m. By setting the vertical height of the U-shaped rod between 1.1 m and 1.3 m, the upper end surface of the U-shaped rod can be located near the waist of the staff on the top of the transformer, so as to facilitate the staff to hang the safety hook on the arc-shaped rod or the U-shaped rod.
[0011] Preferably, the length extension direction of the U-shaped rod is consistent with the length extension direction of the transformer. By making the length extension direction of the U-shaped rod consistent with the length extension direction of the transformer, the stability of the device during use can be improved, and when the staff accidentally falls, the safety belt and the base can be prevented from rubbing against each other.
[0012] Preferably, two arc-shaped rods are arranged at the top of the U-shaped rod, and the two arc-shaped rods are equidistantly distributed along the length extension direction of the U-shaped rod. By arranging two arc-shaped rods at the top of the U-shaped rod and the two arc-shaped rods being equidistantly distributed along the length extension direction of the U-shaped rod, the safety of the staff when moving on the top of the transformer can be ensured.
[0013] Preferably, a cross bar fixedly connected to the end of the arc-shaped rod and welded to the U-shaped rod is provided. The cross bar extends horizontally away from the arc-shaped rod, and the length extension direction of the cross bar is consistent with the length extension direction of the U-shaped rod. By fixedly connecting a cross bar welded to the U-shaped rod at the end of the arc-shaped rod, and the cross bar extending horizontally away from the arc-shaped rod, and the length extension direction of the cross bar being consistent with the length extension direction of the U-shaped rod, the welding contact area between the arc-shaped rod and the U-shaped rod can be increased by using the cross bar, thereby improving the connection effect between the arc-shaped rod and the U-shaped rod during the use of the device.
[0014] The beneficial effects of the present utility model are as follows: By fixedly installing a U-shaped rod on the top of the transformer, and fixedly connecting an arc-shaped rod to the top of the U-shaped rod, and both the openings of the U-shaped rod and the arc-shaped rod face downward, the vertical distance between the arc top of the arc-shaped rod and the U-shaped rod forms a safety belt fixing space. When the device is in use, a worker climbing to the top of the transformer moves and presses the safety hook on the safety belt, so that the safety hook penetrates into the safety belt fixing space, and then releases the safety hook, so that the safety hook hangs on the arc-shaped rod or the U-shaped rod, thereby connecting the worker to the arc-shaped rod or the U-shaped rod through the safety belt. This can not only improve the safety of the workers on the top of the transformer, prevent the workers from falling off the transformer, but also play a limiting role on the safety hook on the safety belt, prevent the safety hook from moving in the horizontal direction, and improve the stability of the safety belt during the use of the device.

[0021] To clearly illustrate the technical features of this solution, the following is an elaboration of this solution through specific embodiments.
[0022] As Figures 1 - 4The transformer top safety belt hanging device of the utility model is shown, a U-shaped rod 1 is fixedly installed on the top of the transformer 2, an arc rod 3 is fixedly connected to the top of the U-shaped rod 1, the openings of the U-shaped rod 1 and the arc rod 3 are both facing downward, and the vertical distance between the arc rod 3 and the U-shaped rod 1 forms a safety belt fixing space.
[0023] By installing a base 8 fixedly connected to the top of the transformer 2 at the bottom of the U-shaped rod 1, the base 8 can be used to facilitate the staff to fix the U-shaped rod 1 on the transformer 2. By setting three U-shaped rods 1 on the top of the transformer 2, and the three U-shaped rods 1 are equidistantly distributed along the length extension direction of the transformer 2, the safety of the staff when moving on the top of the transformer 2 can be ensured. By fixing a first flange 6 at the bottom of the U-shaped rod 1, fixing a second flange 7 at the top of the base 8, and fixing the first flange 6 and the second flange 7 through a threaded rod 5, the threaded rod 5 is rotated to disengage from the first flange 6 and the second flange 7, and the first flange 6 and the second flange 7 are no longer fixedly connected, so that it is convenient for the staff to replace the arc rod 3 or the U-shaped rod 1 when it is rusted and damaged. By setting the vertical height of the U-shaped rod 1 to 1.1~1.3m, the upper end surface of the U-shaped rod 1 can be located near the waist of the staff at the top of the transformer 2, so that it is convenient for the staff to hang the safety hook on the arc rod 3 or the U-shaped rod 1. By making the length extension direction of the U-shaped rod 1 consistent with the length extension direction of the transformer 2, the stability of the device during use can be improved, and the safety belt and the base 8 can be prevented from being scratched when the staff accidentally falls. By providing two arc-shaped rods 3 at the top of the U-shaped rod 1, and the two arc-shaped rods 3 are equidistantly distributed along the length extension direction of the U-shaped rod 1, the safety of the staff when moving on the top of the transformer 2 can be guaranteed. By fixing a cross bar 4 welded to the U-shaped rod 1 at the end of the arc-shaped rod 3, and the cross bar 4 extends laterally in a direction away from the arc-shaped rod 3, the length extension direction of the cross bar 4 is consistent with the length extension direction of the U-shaped rod 1, and the cross bar 4 can be used to increase the welding contact area between the arc-shaped rod 3 and the U-shaped rod 1, thereby improving the connection effect between the arc-shaped rod 3 and the U-shaped rod 1 during use of the device.
[0024] Combined with Figures 1 - 4It can be seen that the usage method of the present utility model is as follows: When the staff climbs to the top of the transformer 2, by moving and pressing the safety hook on the safety belt, the safety hook is inserted into the safety belt fixing space, and then the safety hook is released, so that the safety hook is hung on the arc-shaped rod 3 or the U-shaped rod 1, thereby connecting the staff to the arc-shaped rod 3 or the U-shaped rod 1 through the safety rope. When the staff needs to move on the top of the transformer 2, by moving and pressing the safety hook on another safety belt, the safety hook on the other safety belt is inserted into the fixing space of other safety belts, and then the safety hook on the other safety belt is released, so that the safety hook on the other safety belt is hung on the arc-shaped rod 3 or the U-shaped rod 1. Then, by pressing and moving the safety hook initially hung on the arc-shaped rod 3 or the U-shaped rod 1, the safety hook initially hung on the arc-shaped rod 3 or the U-shaped rod 1 is removed from the safety belt fixing space and is no longer hung on the arc-shaped rod 3 or the U-shaped rod 1, so as to ensure the safety of the staff during movement.
