[0026] In order to make the technical purpose, technical solution and beneficial effects of the utility model clearer, the technical solution of the utility model is further described below in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings can be arranged and designed in various different configurations.

[0027] The specific embodiment of the high-altitude power maintenance tool anti-falling device involved in the utility model is as follows: Figures 1 to 4As shown, the anti-fall device for tools for high-altitude power maintenance includes a fixing seat 1, and the fixing seat 1 has an air cavity 11 therein. Specifically, the fixing seat 1 is a rectangular plate structure as a whole, and has an air cavity 11 extending up and down therein. An air hole connected to the air cavity 11 is provided at the top of the fixing seat 1, and a plurality of fixing suction cups 2 connected to the air cavity 11 are provided on the right and left sides of the fixing seat 1. Specifically, a connecting hole 13 extending rightward and connected to the air cavity 11 is provided on the left side wall of the fixing seat 1, and the fixing suction cup 2 is sealed and assembled in the connecting hole 13, and the right end of the fixing suction cup 2 is located in the air cavity 11 to form a vent 21. When the fixing suction cup 2 is pressed against the external surface, the gas in the fixing suction cup 2 is squeezed to the right through the vent 21 into the air cavity 11, and then discharged outward through the air hole of the air cavity 11. At this time, the fixing suction cup 2 is squeezed.

[0028] In order to achieve stable adsorption of the fixed suction cup 2, a plug 6 is arranged in the air cavity 11 and is used to block the vent 21 to seal the fixed suction cup 2. The fixed seat 1 is also provided with a reset member for applying a force to the plug 6 to move toward the vent 21. The fixed seat 1 is also provided with a pulling structure for connecting with the plug 6 and separating the plug 6 from the vent 21.

[0029] As a preferred embodiment, the plug 6 is connected to a guide rod 7 which is guided and installed in the fixing seat 1. The axis of the guide rod 7 is consistent with the axis of the fixed suction cup 2. The reset member is a reset spring 8 which is installed between the guide rod 7 and the fixing seat 1. The tail end of the guide rod 7 is connected to the pulling structure. In actual operation, the pulling structure pulls the guide rod 7 to move to the right, driving the plug 6 to move away from the vent 21 to the right, so that the vent 21 can be connected with the air cavity 11. When the pulling structure is not operated, the guide rod 7 is driven by the force of the reset member to move the plug 6 to the left, and is tightly pressed on the vent 21, so that the vent 21 and the air cavity 11 are completely closed and isolated. In order to ensure air tightness, the plug 6 in this embodiment is made of rubber.

[0030] Preferably, in order to ensure the stable movement of the guide rod 7, a guide hole 14 extending to the left and penetrating the air cavity 11 is provided on the right side of the fixed seat 1, and the guide rod 7 is guided and assembled with the guide hole 14. The pulling structure is a pull rope 9 inserted into the guide hole 14, and a reversing structure for guiding the reversal of the pull rope 9 is provided around the right end of the guide hole 14 on the fixed seat 1. The reversing structure is mainly provided to meet the different pulling directions of the rope and to avoid wear between the pull rope 9 and the fixed seat 1. Specifically, the reversing structure is a reversing wheel 17, and there are two reversing wheels 17, which are arranged side by side in the vertical direction, and the space between the two reversing wheels 17 is for the pull rope 9 to pass through. In order to avoid the pull rope 9 swinging back and forth to affect the line of sight when working at a height and to further facilitate pulling, a limit cylinder 19 for the pull rope 9 to pass through is also provided on the fixed seat 1 below the guide hole 14, and a pull ring is provided at the tail end of the pull rope 9.

[0031] As a preferred embodiment, in order to meet the requirements of hoisting the tool 5, in this embodiment, the fixed seat 1 is also connected to a tool placement plate 3, and a plurality of placement seats 4 are arranged on the tool placement plate 3. The placement seats 4 are provided with hanging rods 43 for hanging the tool 5. The hanging rod 43 is unlocked by the tool 5 so that the tool 5 can be moved out from the hanging rod 43.

[0032] In order to realize the automatic hanging of the tool 5, a through slot 42 is provided on the placement seat 4, a hanging rod 43 is hingedly connected in the through slot 42, the hinge axis extends horizontally, one end of the hanging rod 43 is placed on the placement seat 4, and is matched with the upper and lower stopper of the placement seat 4, and a torsion spring 45 is connected between the hanging rod 43 and the through slot 42 to apply a swinging force to the hanging rod 43 toward the stopper 44. Specifically, in order to realize the protection of the tool 5 and prevent the tool 5 from falling due to accidental touch, the placement seat 4 has a receiving hole 41 that passes through from top to bottom, a stopper 44 is suspended on the right side wall of the receiving hole 41, the through slot 42 is arranged on the left side wall of the receiving hole 41, and the hanging rod 43 is placed on the upper end surface of the stopper 44.

[0033] In order to meet the connection between the tool placement plate 3 and the fixing seat 1 and adapt to the placement of different types of tools 5, the tool placement plate 3 is hooked and connected to the fixing seat 1, and a locking nut 18 is also connected between the fixing seat 1 and the tool placement plate 3 to lock and fix the two behind the hook 16. Specifically, a hook 16 is provided on the fixing seat 1, and a hanging hole 32 is arranged at the same height on the tool placement plate 3, and the two are hooked and matched; at the same time, a screw rod 1615 is opened and fixed on the fixing seat 1, and the screw rod 1615 extends horizontally, and a corresponding long hole 31 is opened on the tool placement plate 3. After the screw rod 1615 passes through the long hole 31, the tool placement plate 3 is locked on the fixing seat 1 through the locking nut 18.

[0034] In actual use, first fix the tool placement plate 3 on the fixing seat 1, insert the tools 5 into the accommodating holes 41 one by one from bottom to top, and then push the hanging rod 43 upward. After the hanging rod 43 swings upward, when passing through the hanging hole 32 of the tool 5, it is driven by the torsion spring 45 to swing downward and lock, so that the tool 5 is hung on the hanging rod 43. When it is necessary to remove the tool 5, just continue to push the tool 5 upward, swing the hanging rod 43 upward, and then move the tool 5 horizontally forward or backward to achieve the removal of the tool 5.

[0035] Then the fixing base 1 is attached to the surface of the target object, and the gas in the suction cup is squeezed and pushes the plug 6 to the right. After the gas enters the air cavity 11, the gas on the surface of the suction cup is squeezed out, and the plug 6 is reversely blocked at the vent 21 by the push of the reset spring 8. At this time, an air pressure difference is generated between the surface and the inside of the suction cup, which can make the fixed suction cup 2 stably adsorbed on the target object. When the fixing base 1 needs to be disassembled, the worker can directly pull and lift it to separate the vent 21 from the plug 6, and the gas in the air cavity 11 enters the suction cup to complete the disassembly.

[0036] Of course, in other embodiments, there are multiple fixed suction cups 2, and the pull ropes 9 corresponding to the multiple fixed suction cups 2 can be pulled uniformly with one rope to achieve synchronous unlocking.

[0037] In other embodiments, the pulling structure may also be in other forms such as a rigid rod, a pin shaft, etc.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate but not limit the technical solutions of the present utility model. Any equivalent substitutions of the present utility model and any modifications or partial substitutions that do not depart from the spirit and scope of the present utility model should be included in the scope of protection of the claims of the present utility model.
