[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution:

[0024] A powerful adsorption device for high-altitude operations without hanging points includes two symmetrically distributed electric suction cup bodies 1. A connecting plate 1 and a connecting plate 2 are fixedly connected to the side walls of the two electric suction cup bodies 1 respectively. The connecting plate 1 and the connecting plate 2 are rotatably connected. A rotating shaft 7 is rotatably connected inside the connecting plate 1 and the connecting plate 2. A limiting component 8 for fixing the angle between the two connecting plates is provided at the upper end of the connecting plate 2.

[0025] A temperature measuring component 9 for detecting the temperature of the adsorption surface is provided on the side wall of the connecting plate 5.

[0026] For example, the electric suction cup body 1 is provided with a handle 2, a hanging ring 3, and a first switch 4. The handle 2 facilitates the movement of the electric suction cup body 1, the hanging ring 3 is connected to the safety rope, and the first switch 4 controls the start and stop of the electric suction cup body 1. The recommended model of the electric suction cup body 1 is: pi Compact 21.

[0027] The limiting assembly 8 includes two fixed brackets 81 fixedly installed on the upper end of the connecting plate 2 6. Springs 82 are provided on the outer side of each of the two fixed brackets 81. Lifting plates 83 are slidably connected to the outer side of each of the two fixed brackets 81. The lifting plates 83 are in contact with the connecting plate 1 5 and the connecting plate 2 6 respectively. A plurality of limiting rods 84 distributed in a ring are fixedly connected to the lower end of the lifting plate 83. The plurality of limiting rods 84 are made of damping material. A plurality of limiting holes 85 distributed in a ring are opened on the upper end of the connecting plate 1 5. The plurality of limiting holes 85 are slidably connected to the plurality of limiting rods 84 respectively.

[0028] For example, when working on a curved wall, the lifting plate 83 is moved upward, pressing the spring 82. The lifting plate 83 drives the limiting rod 84 to disengage from the limiting hole 85. The angle between the connecting plate 1 5 and the connecting plate 2 6 is adjusted so that both electric suction cup bodies 1 can be pressed against the wall. When the lifting plate 83 is released, it moves downward under the elastic force of the spring 82, causing the limiting rod 84 to be locked inside the limiting hole 85, fixing the connecting plate 1 5 and the connecting plate 2 6 and preventing them from rotating. The limiting rod 84 is made of damping material to prevent it from easily disengaging from the limiting hole 85.

[0029] The temperature measuring component 9 includes a heat insulation tube 91 fixedly installed on the side wall of the connecting plate 5. One end of the heat insulation tube 91 is fixedly connected to a heat conducting block 92. A piston 93 is slidably connected inside the heat insulation tube 91. A limit ring 94 is fixedly connected inside the heat insulation tube 91. The other end of the heat insulation tube 91 is fixedly connected to a fixing plate 95. A second switch 96 is fixedly connected to the side wall of the fixing plate 95.

[0030] For example, the heat-conducting block 92 contacts the adsorption surface, conducting the temperature of the adsorption surface to the interior of the heat insulation tube 91. As the temperature inside the heat insulation tube 91 rises, the air inside the heat insulation tube 91 expands due to heat, causing the piston 93 to move. When the piston 93 contacts the second switch 96, the second switch 96 opens, and the limiting ring 94 limits the piston 93 to prevent the piston 93 from damaging the second switch 96.

[0031] An alarm light 10 is fixedly connected to the side wall of the connecting plate 5. The alarm light 10 is electrically connected to the second switch 96. A buzzer 11 is fixedly connected to the side wall of the connecting plate 5. The buzzer 11 is electrically connected to the second switch 96.

[0032] For example, when the second switch 96 is turned on, the control alarm light 10 and the buzzer 11 start working simultaneously to warn personnel working at height. The recommended model of the alarm light 10 is Werma 041.210 (Germany), and the recommended model of the buzzer 11 is Murata PKMCS0909E4000-R1.

[0033] Working principle: When using this utility model, the device is used in conjunction with safety ropes and other safety measures. The device can also be used in sets or more to improve safety. The high-altitude worker carries his own power supply and can easily move the electric suction cup body 1 through the handle 2. The hanging ring 3 is connected to the safety rope. The first switch 4 controls the start and stop of the electric suction cup body 1. The electric suction cup body 1 is attached to the wall to fix the high-altitude worker. When it is necessary to move, the electric suction cup body 1 is turned off and the position of the electric suction cup body 1 is adjusted.

[0034] When the electric suction cup body 1 is working, the heat-conducting block 92 contacts the adsorption surface, conducting the temperature of the adsorption surface to the interior of the heat insulation tube 91. As the temperature inside the heat insulation tube 91 rises, the air inside the heat insulation tube 91 expands due to heat, driving the piston 93 to move. When the piston 93 contacts the second switch 96, the second switch 96 opens, and the limiting ring 94 limits the piston 93 to prevent the piston 93 from damaging the second switch 96. When the second switch 96 opens, the alarm light 10 and the buzzer 11 start working simultaneously to warn workers at height and prevent the temperature from getting too high, which would reduce the adsorption effect of the electric suction cup body 1 and cause workers at height to fall off the wall. Before use, the device should be adjusted. When the temperature reaches 50 degrees, the piston 93 can easily contact the second switch 96. When the temperature reaches 60 degrees, it will have a significant impact on the adsorption of the electric suction cup body 1. This is in accordance with EN 795:2012 Class C.

[0035] When working on a curved wall, the lifting plate 83 is moved upward, pressing the spring 82. The lifting plate 83 then moves the limiting rod 84 away from the limiting hole 85, adjusting the angle between connecting plate 1 5 and connecting plate 2 6 so that both electric suction cup bodies 1 can be pressed against the wall. When the lifting plate 83 is released, it moves downward under the elastic force of the spring 82, causing the limiting rod 84 to lock inside the limiting hole 85, fixing connecting plate 1 5 and connecting plate 2 6 and preventing them from rotating.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
