[0002] To meet operational requirements, most electrical equipment is located at heights exceeding two meters. Therefore, equipment maintenance often requires climbing, leading to frequent falls during electrical construction. To prevent such incidents, workers must wear safety belts during operation, which require attachment points to secure them.

[0003] In the prior art, some hanging point devices require that the fixed rod be fixed to the ground on the side of the transformer, and then the side pull rod be fixed to the ground on the side of the fixed rod, and then both ends of the hanging rope be fixed to the side pull rod and ensure that the bottom ends thereof are in contact with the top of the lifting rod, and then the lifting rod is driven to slide upward along the inner wall of the fixed rod to lift the hanging rope above the transformer, and finally the safety belt is hung on the hanging rope to start the operation. However, this hanging point device is in contact with the ground and the hanging rope needs to be lifted above the transformer, which makes it inconvenient to store and transport. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of the present utility model is to provide a hanging point device for a safety belt in electric power construction work, so as to solve the problem that some hanging point devices proposed in the above background technology are in contact with the ground and the hanging rope needs to be lifted above the transformer, resulting in the overall height being high and inconvenient for storage and transportation.

[0005] The harness includes a first end, a second end of which is fixedly provided with a hook, and a second end of which is pivotally connected to the first gear and a third end of which is pivotally connected to the second gear.

[0006] Furthermore, an anti-slip layer is fixedly connected to a side of the locking plate away from the threaded rod, and a size of the anti-slip layer is consistent with a size of the locking plate.

[0007] Furthermore, one end of the rope collecting frame extends out of the fixing frame fixedly connected to a ratchet, the side of the fixing frame close to the ratchet is rotatably connected to a pawl, the side of the fixing frame close to the ratchet is fixedly connected to a return spring located above the pawl, and the return spring and the pawl are fixedly connected.

[0008] Furthermore, a rope groove is provided at the top end of the support rod, and the rope groove is U-shaped.

[0009] Furthermore, the top of the hook is in an "n" shape, and the hanging ring and the hook are movably connected.

[0010] Furthermore, the top surface of the first clamping plate is flush with the top surface of the second clamping plate, and the inner wall of the bottom end of the rope groove is higher than the top surface of the first clamping plate.

[0011] The beneficial effects of the utility model are as follows: the locking plate is pushed toward the edge of the transformer by the threaded rod and the guide rod, and the first clamping plate and the second clamping plate are fixed to the top of the transformer. Then, the hanging rope is pulled and passed through the support rod in sequence. During this process, the rope collecting frame rotates in the fixing frame and causes the coil spring to deform. Next, the hanging ring is put onto the hook surface. The installation of the hanging point device can be completed through the above steps. Finally, the safety belt is hung on the hanging rope surface and the operation can be started. The whole device is small in size and easy to carry. When the worker moves, the safety belt will slide along the hanging rope surface, which is convenient for the worker to operate.

[0012] The ratchet and pawl can prevent the rope collection frame from reversing under the action of the coil spring due to the worker not pulling the hanging rope when installing the device. The reset spring ensures that the pawl can always be in contact with the ratchet. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 5 The utility model provides a technical solution: a hanging point device for a safety belt of an electric power construction operation, comprising a first splint 1, a second splint 2 is provided on one side of the first splint 1, and the first splint 1 and the second splint 2 are both movably connected to two guide rods 3, and the first splint 1 and the second splint 2 are threadedly connected between the two guide rods 3, and the top of the guide rod 3 is fixedly connected to a locking plate 5. The first splint 1 and the top of the second splint 2 are both fixedly connected to the support rod 6, one side of the first splint 1 is fixedly connected to a hook 7, and one side of the second splint 2 is fixedly connected to a fixing frame 8, a rope collection frame 9 is rotatably connected to the fixing frame 8, and a protective shell 10 is fixedly connected to one side of the fixing frame 8. A coil spring 11 is provided in the protective shell 10, and the coil spring 11 has an outer end and an inner end. The outer end is fixedly connected to the protective shell 10, and the inner end is fixedly connected to the rope collection frame 9. A hanging rope 12 is fixedly connected to the surface of the rope collection frame 9, and a hanging ring 13 is fixedly connected to the side of the hanging rope 12 away from the rope collection frame 9.

[0022] The locking plate 5 is pushed toward the edge of the transformer by the threaded rod 4 and the guide rod 3, and the first clamping plate 1 and the second clamping plate 2 are fixed to the top of the transformer. Then the hanging rope 12 is pulled and passed through the support rod 6 in sequence. During this process, the rope-collecting frame 9 will rotate in the fixing frame 8 and cause the coil spring 11 to deform. After the hanging ring 13 connected to the hanging rope 12 is moved above the hook 7, the hanging ring 13 is put onto the surface of the hook 7. The installation of the hanging point device can be completed through the above steps. Finally, the safety belt is hung on the surface of the hanging rope 12 and the operation can be started. The whole device is small in size and easy to carry. When the worker moves, the safety belt will slide along the surface of the hanging rope 12, which is convenient for the worker to operate.

[0023] See also Figures 1 to 5 The present invention provides a technical solution: an anti-slip layer 14 is fixedly connected to the side of the locking plate 5 away from the threaded rod 4. The size of the anti-slip layer 14 matches the size of the locking plate 5. By providing the anti-slip layer 14 with the same size as the locking plate 5, the friction between the locking plate 5 and the transformer is increased, thereby further improving the firmness of the connection between the device and the transformer.

[0024] One end of the rope-collecting frame 9 extends from a fixing frame 8, which is fixedly connected to a ratchet 15. A pawl 16 is rotatably connected to the side of the fixing frame 8 near the ratchet 15. A return spring 17 is fixedly connected to the side of the fixing frame 8 near the ratchet 15, above the pawl 16. The return spring 17 is fixedly connected to the pawl 16. The ratchet 15 and pawl 16 prevent the rope-collecting frame 9 from reversing due to the coil spring 11 if a worker fails to hold the hanging rope 12 during installation. The return spring 17, in conjunction with the return spring 17, ensures that the pawl 16 remains in constant contact with the ratchet 15.

[0025] A rope groove 18 is provided at the top of the support rod 6, and the rope groove 18 is " U " shaped. By arranging the rope groove 18 in " U " shape at the top of the support rod 6, the hanging rope 12 can be limited.

[0026] The top of the hook 7 is in an "n" shape, and the hanging ring 13 is movably connected with the hook 7. The top of the hook 7 is in an "n" shape to prevent the hanging ring 13 from breaking away from the hook 7 during use.

[0027] The top surface of the first plate 1 is flush with the top surface of the second plate 2, and the inner wall of the bottom end of the rope groove 18 is higher than the top surface of the first plate 1. The top surface of the first plate 1 is flush with the top surface of the second plate 2, and the inner wall of the bottom end of the rope groove 18 is higher than the top surface of the first plate 1 to prevent the hanging rope 12 in the rope groove 18 from rubbing against the top of the first plate 1 and the top of the second plate 2, thereby reducing wear on the hanging rope 12.

[0028] When the harness is secured to the ground, the harness 1 is secured to the base 1 and the second harness 1 is secured to the base 1. When the harness is secured to the ground, the harness 1 is secured to the base 1 and the second harness 1 is secured to the base 1.

[0029] When the rope collecting frame 9 rotates in the fixing frame 8, it will drive the ratchet 15 connected to the fixing frame 8 to rotate. Cooperating with the pawl 16, it can prevent the rope collecting frame 9 from reversing under the action of the coil spring 11 due to the worker not pulling the hanging rope 12 when installing the device. The return spring 17 fixed to the side of the fixing frame 8 ensures that the pawl 16 can always be in contact with the ratchet 15.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
