[0001] The invention belongs to the technical field of auxiliary devices, in particular to an auxiliary device for installing electric wires and cables. Background Art

[0002] Wires and cables are electrical transmission lines widely used in power, communications, transportation, construction and other fields. They are composed of one or more insulated cores covered with a protective layer. Their main function is to achieve the transmission and distribution of electrical energy, as well as the transmission and reception of signals.

[0003] When laying cables on electric poles, professional technicians need to climb to the top of the pole to perform the task. They usually use foot buckles and ascend alternately to gradually climb higher, while also carrying one end of the cable. During this process, when the operator tries to install the cable, he must hold the cable with one hand, and the cable will naturally sag due to the influence of gravity. This situation undoubtedly increases the complexity and difficulty of the operation, making the operation particularly difficult.

[0004] To this end, the present invention provides an auxiliary device for installing wires and cables. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0032] Embodiment 1: Figures 1 to 6 As shown, an auxiliary device for installing electric wires and cables according to an embodiment of the present invention comprises an electric pole 1, a cable 2, a first mounting block 3 and a second mounting block 4, wherein the first mounting block 3 and the second mounting block 4 are detachably mounted;

[0033] Both sides of the first mounting block 3 and the second mounting block 4 are provided with connecting ears, and the connecting ears on the first mounting block 3 and the second mounting block 4 can be installed by bolts. When in use, the first mounting block 3 and the second mounting block 4 are sleeved on the outer wall of the pole 1, and then the first mounting block 3 and the second mounting block 4 are installed by bolts.

[0034] A wire drum 13 is slidably mounted inside the second mounting block 4 and is used to provide a path for the cable 2;

[0035] A locking assembly, disposed on the wire barrel 13, for locking the cable 2 inside the wire barrel 13;

[0036] The wire drum 13 is provided with a hole groove for the cable 2 to pass through. When the first mounting block 3 and the second mounting block 4 are installed on the electric pole 1, the cable 2 can be passed through the hole groove provided on the wire drum 13. At this time, the position of the cable 2 can be locked by using the locking component.

[0037] An extension assembly, disposed inside the second mounting block 4, for controlling the sliding movement of the bobbin 13 inside the second mounting block 4;

[0038] By means of the extending assembly, the wire reel 13 can be extended from the top of the second mounting block 4, and the cable 2 locked by the locking assembly can be brought out together. By stretching the cable 2 in this way, the problem that the cable 2 is inconvenient to operate under the action of gravity when working at heights can be effectively solved.

[0039] The positioning block 15 is slidably mounted inside the first mounting block 3 , and a pulley 16 is rotatably mounted inside the positioning block 15 . One end of the pulley 16 extends out of the outer wall of the positioning block 15 and fits against the outer wall of the pole 1 .

[0040] When the first mounting block 3 and the second mounting block 4 are mounted on the electric pole 1 , they can slide on the electric pole 1 through the provided pulley 16 , and can be easily climbed to the top of the electric pole 1 .

[0041] This is a preferred embodiment of the present invention. The locking assembly includes a plug rod 6, a second ring 7, a plug groove 5 and a pushing assembly. The second ring 7 is fixedly mounted on the outer wall of the wire barrel 13, the plug rod 6 is elastically mounted inside the second ring 7, the plug groove 5 is provided on the wire barrel 13, and the sliding of the plug rod 6 is controlled by the pushing assembly.

[0042] There are multiple plug-in rods 6 and plug-in slots 5.

[0043] The plug-in slot 5 is a through slot, and a spring is provided between the plug-in rod 6 and the second ring 7 .

[0044] When the cable 2 passes through the interior of the wire drum 13, the plug rod 6 is pushed to make the plug rod 6 slide into the inner cavity of the plug slot 5. At this time, the spring on the plug rod 6 will be deformed and store elastic potential energy. After the plug rod 6 is inserted into the plug slot 5, the outer wall of the cable 2 is squeezed by the plug rod 6. By setting multiple plug rods 6 to press the surrounding of the cable 2 at the same time, the movement of the cable 2 can be restricted, thereby achieving the effect of locking the cable 2. At this time, it is only necessary to control the wire drum 13 to move in the second mounting block 4 to drive the cable 2 to stretch at the same time.

[0045] This is a preferred embodiment of the present invention, and the pushing assembly includes a first ring 25, a receiving groove 26 and an arc-shaped top block 27. The first ring 25 is rotatably mounted on the outer wall of the second ring 7, the receiving groove 26 is opened on the inner wall of the first ring 25, and the arc-shaped top block 27 is fixedly mounted on the inner wall of the receiving groove 26. The number of arc-shaped top blocks 27 is consistent with the number of plug-in rods 6.

[0046] By rotating the first ring 25, the arc-shaped top block 27 inside the accommodating groove 26 can be driven to slide at the same time. The arc surface on the arc-shaped top block 27 is close to one end of the plug-in rod 6. Therefore, when the first ring 25 drives the arc-shaped top block 27 to rotate, the plug-in rod 6 can be pressed by the setting of the arc surface, so that it slides toward the plug-in groove 5 until the plug-in rod 6 slides into the plug-in groove 5 and presses the outer wall of the cable 2. By rotating the first ring 25 in the opposite direction, the arc-shaped top block 27 can be driven to release the pressure on the plug-in rod 6, and the elastic potential energy is released by the spring, so that the plug-in rod 6 is pulled out of the plug-in groove 5 and returns to the inner cavity of the accommodating groove 26. At this time, the cable 2 will not be locked.

[0047] The first ring 25 and the second ring 7 are connected by threads, which can effectively prevent the first ring 25 from being pressed and reversed, thereby causing the clamping of the cable 2 to be unstable.

[0048] This is a preferred embodiment of the present invention. The extension component includes a rotating drum 11, a spiral groove 12 and a guide block 14. The rotating drum 11 is rotatably mounted on the outer wall of the line drum 13. The spiral groove 12 is opened on the inner wall of the rotating drum 11. The guide block 14 is fixedly mounted on the outer wall of the line drum 13. One end of the guide block 14 extends to the interior of the spiral groove 12.

[0049] When the drum 11 rotates, the guide block 14 on the bobbin 13 moves along the track formed by the spiral groove 12, so that the bobbin 13 rotates and moves up or down. By controlling the rotation direction of the drum 11, the bobbin 13 can be controlled to move up or down.

[0050] This is a preferred embodiment of the present invention. A worm wheel 10 is fixedly mounted on the bottom end of the rotating drum 11. A worm 9 adapted to the worm wheel 10 is rotatably mounted inside the second mounting block 4. One end of the worm 9 extends out of the outer wall of the second mounting block 4 and is fixedly mounted with a knob 8.

[0051] By turning the knob 8, the worm 9 can be driven to rotate, and by the worm 9 driving the worm wheel 10 to rotate, the rotation of the rotating drum 11 can be controlled. Through the characteristics of the worm wheel 10 and the worm 9, the rotation of the rotating drum 11 can be limited, and the movement of the bobbin 13 can only be controlled by turning the knob 8.

[0052] This is a preferred embodiment of the present invention. A rotating rod 17 is fixedly mounted on the side wall of the pulley 16 , a ratchet 18 is fixedly mounted on the outer wall of the rotating rod 17 , a ratchet rod 19 is elastically mounted inside the positioning block 15 , and the ratchet rod 19 is adapted to the ratchet 18 .

[0053] The ratchet rod 19 is installed inside the positioning block 15 through a torsion spring, so that the ratchet rod 19 always keeps blocking the ratchet 18. When the pulley 16 fits the electric pole 1, the first mounting block 3 and the second mounting block 4 are pulled upward. Under the action of friction, the pulley 16 in the positioning block 15 will rotate clockwise. At this time, the ratchet rod 19 will not block the ratchet 18 rotating clockwise. However, when the first mounting block 3 and the second mounting block 4 slide downward on the electric pole 1, the pulley 16 will rotate counterclockwise and drive the ratchet 18 to rotate counterclockwise. At this time, the ratchet rod 19 will block the counterclockwise rotation of the ratchet 18, which can effectively prevent the first mounting block 3 and the second mounting block 4 from sliding up and down the electric pole 1 under the action of gravity. The surface of the pulley 16 can be set to rubber material to further increase the friction.

[0054] This is a preferred embodiment of the present invention. A pull rope 20 is fixedly connected to the top of the ratchet rod 19 , a hook 21 is slidably mounted on the top of the first mounting block 3 , and the bottom end of the hook 21 is fixedly connected to the pull rope 20 .

[0055] By pulling the pull rope 20 , the ratchet rod 19 can be driven to rotate, thereby releasing the blockage of the ratchet wheel 18 . Therefore, by controlling the ratchet rod 19 to release the blockage of the ratchet wheel 18 , the first mounting block 3 and the second mounting block 4 can slide downward from the electric pole 1 .

[0056] The hook 21 is obliquely arranged at the top of the first mounting block 3. By applying a pulling force to the hook 21, the hook 21 slides and drives the pull rope 20 to release the blocking of the ratchet rod 19 to the ratchet wheel 18, so that the pulley 16 can rotate arbitrarily.

[0057] This is a preferred embodiment of the present invention. A pressing block 22 for pressing the positioning block 15 is rotatably installed inside the first mounting block 3. The pressing block 22 is configured to be L-shaped.

[0058] One end of the pressing block 22 is in contact with the positioning block 15. When the pressing block 22 rotates toward the positioning block 15, the positioning block 15 can be pushed by the shape of the pressing block 22. At this time, the positioning block 15 will also drive the pulley 16 to increase the squeezing of the pole 1. The pulley 16 is further pressed against the outer wall of the pole 1 to increase the friction force, thereby preventing the first mounting block 3 and the second mounting block 4 from sliding on the pole 1.

[0059] It is a preferred embodiment of the present invention, a pressing roller 23 for pressing the pressing block 22 is slidably installed inside the first mounting block 3, a dragging rope 24 is fixedly connected to the pressing roller 23, and a buckle is provided at the top of the dragging rope 24.

[0060] The buckle arranged on the towing rope 24 can be connected with the safety belt of the staff. When the first mounting block 3 and the second mounting block 4 are installed on the electric pole 1, when the staff wears the foot buckles on their feet and climbs on the electric pole 1, the towing rope 24 can apply an upward pulling force to the first mounting block 3. At this time, the first mounting block 3 and the second mounting block 4 can slide on the electric pole 1 through the pulley 16. If an accident occurs and causes the staff to fall, the staff will quickly pull the towing rope 24 downward under the action of gravity, and at the same time make the top pressure roller 23 slide downward inside the first mounting block 3, and press the top pressure block 22, so that the top pressure block 22 applies a force toward the positioning block 15, thereby increasing the friction between the pulley 16 and the electric pole 1, and effectively protecting the staff.

[0061] When the staff finishes their work and needs to release the restriction of the pulley 16, they can put the towing rope 24 on the inclined hook 21. At this time, the towing rope 24 will give a pulling force to the hook 21, causing the hook 21 to slide upward inside the first mounting block 3, and the pull rope 20 will contact the ratchet rod 19 to block the ratchet 18, so that the pulley 16 can rotate normally.

[0062] Working principle: by inserting the cable 2 into the interior of the wire drum 13, and then rotating the first ring 25, the arc-shaped top block 27 is driven to press the plug-in rod 6, so that it slides toward the plug-in slot 5, until the plug-in rod 6 slides into the plug-in slot 5 and presses against the outer wall of the cable 2, at which time the cable 2 can be locked.

[0063] Then, by turning the knob 8, the worm 9 and the worm wheel 10 are driven to rotate, and the rotating drum 11 is controlled to rotate. At this time, the guide block 14 on the wire drum 13 will move along the track opened by the spiral groove 12, so that the wire drum 13 can slide upward, and the cable 2 can be extended in a locked state, which can improve the efficiency of the staff in installing the cable 2.

[0064] When the worker falls, the drag rope 24 can drive the drag rope 24 and the pressure roller 23 to pull downward under the action of the worker's weight, and press the pressure block 22, so that the pressure block 22 applies a force toward the positioning block 15, increasing the friction between the pulley 16 and the pole 1, limiting the movement of the first mounting block 3 and the second mounting block 4, and effectively protecting the worker.

Figure 1As a benchmark, according to the person's observation perspective, the side of the device facing the observer is defined as the front, the left side of the observer is defined as the left, and so on.
