Description

Technical Field

[0001] The utility model belongs to the technical field of cable spreading, and in particular relates to an auxiliary device for installing a power cable. Background Art

[0002] During cable installation, workers are required to spread the cables rolled up on cable rollers on one side of the installation tunnel. Since the friction between the cables and the ground during movement will damage the outer sheath of the cables, a protective device is required to isolate the cables from contact with the ground during the cable spreading process. The current protective device raises the height of the cables by setting a support frame with a limiting structure on the top to prevent the cables from contacting the ground. However, due to the long length of the cable laying, it will waste a lot of time for the workers to place the protective devices one by one. In addition, the cables need to be placed on the top of the protective device during the cable laying process, and large movements need to be avoided to cause the protective device to tip over. This will greatly increase the cable laying time and affect the cable laying efficiency. Utility Model Content

DETAILED DESCRIPTION

[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: an auxiliary device for installing a power cable, comprising a plurality of movable support base plates 1, a cable limiting guide hook 11 being hinged at the top of the movable support base plate 1, the top of the cable limiting guide hook 11 being bent inward, a connecting socket 12 being provided at the top of the movable support base plate 1, a winding protective shell 2 being fixedly connected to the inner wall of the top of the movable support base plate 1, a cable protection gasket 21 being wound inside the winding protective shell 2, the cable protection gasket 21 being detachably connected to the adjacent movable support base plate 1, and a cable support roller 3 being provided at the top of the winding protective shell 2.

[0017] In this embodiment: when the device is not in use, the cable protection gasket 21 and the lubricating pad layer 22 are rolled up in the winding protection shell 2, and the extrusion and fastening plug block 24 is inserted into the connecting socket 12 of the adjacent mobile support base plate 1. Multiple mobile support base plates 1 are connected to each other. When it is necessary to lay cables, the staff places multiple mobile support base plates 1 on the ground and pulls the outermost mobile support base plate 1 to move. Under the action of traction, the cable protection gasket 21 and the lubricating pad layer 22 are gradually unfolded from the winding protection shell 2, and the mobile support base plate 1 moves on the ground. Then the staff pulls the cable to move on the top of the cable protection gasket 21. The cable protection gasket 21 laid on the ground and the cable support roller 3 cooperate to block the cable from the ground. The cable can be placed in contact with the ground during laying, thereby preventing the cable from being damaged by friction with the ground during laying. When the cable is moved by means of towing of a vehicle, the outermost mobile support base plate 1 is fixed to the vehicle and unfolded with the help of the vehicle towing device. The unfolding of the device and the laying of the cable can be carried out simultaneously, and the laying work can be completed quickly during use. The cable limiting guide hook 11 can guide the falling cable during the cable laying process, and the cable can slide downward along the inclination angle of the cable limiting guide hook 11, and the tail of the cable limiting guide hook 11 is a hook-shaped structure, which can limit the cable that has fallen on the cable support roller 3 to prevent the cable from leaving the range of the device. Compared with the prior art, the device is more convenient in use and can effectively improve the efficiency of cable laying.

[0018] A lubricating pad 22 is fixedly connected to the top of the cable protection gasket 21, and a connecting cross bar 23 is fixedly connected to one end of the cable protection gasket 21 and the lubricating pad 22. An extrusion and fastening plug 24 is fixedly connected to the bottom end of the connecting cross bar 23, and the extrusion and fastening plug 24 is inserted into the connecting socket 12; by providing the lubricating pad 22, the friction between the cable and the cable protection gasket 21 can be further reduced, thereby reducing the resistance encountered by the staff when pulling the cable, and further reducing the friction damage to the cable; by providing the connecting cross bar 23, the tail of the cable protection gasket 21 and the lubricating pad 22 can be flattened to avoid the cable protection gasket 21 and the lubricating pad 22 folding to reduce the protection area; when in use, the staff inserts the extrusion and fastening plug 24 into the connecting socket 12, and then squeezes the connecting cross bar 23 to tightly insert the extrusion and fastening plug 24 into the connecting socket 12; the outside of the extrusion and fastening plug 24 is wrapped with rubber, and the rubber is used to increase the stability of the extrusion and fastening plug 24 after being inserted into the connecting socket 12.

[0019] The outer side of the cable support roller 3 is rotatably connected to a limiting protection groove plate 31, and the limiting protection groove plate 31 is fixedly connected to the top of the winding protection shell 2; by setting the limiting protection groove plate 31, the cable support roller 3 can be limited. When the cable is unfolded, the cable support roller 3 rotates in the limiting protection groove plate 31, and the height of the cable can be lifted by the cable support roller 3 and the limiting protection groove plate 31. With the help of the cable support roller 3 and the limiting protection groove plate 31, most of the weight of the cable can be borne, avoiding that the entire cable is pressed on the cable protection gasket 21 and the lubricating pad layer 22.

[0020] A limiting connecting rod 4 is fixedly connected to one side of the movable support base plate 1, and a plug-in positioning rod 41 which plays a limiting role is inserted at the top of the limiting connecting rod 4; by setting the limiting connecting rod 4 and the plug-in positioning rod 41, the movable support base plate 1 can be fixed to increase the stability of the movable support base plate 1 when the ground is uneven. When the ground is flat, the movable support base plate 1 is directly placed on the ground. When the ground is uneven, the staff drags the movable support base plate 1 to a suitable position and then uses the plug-in positioning rod 41 to pass through the hole of the limiting connecting rod 4 and insert it into the ground, so that the movable support base plate 1 cannot be flipped over, so that the cable protection gasket 21 and the lubricating pad 22 can be smoothly unfolded and laid on the ground.

[0021] A traction rope 5 is detachably connected to the connecting socket 12 on the outermost mobile supporting base plate 1; when the mobile supporting base plate 1 is unfolded and laid, the staff passes the traction rope 5 through the outermost connecting socket 12, and fixes the traction rope 5 and the mobile supporting base plate 1, and then drives the mobile supporting base plate 1 to move by pulling the traction rope 5. When using a vehicle for traction and laying, the staff fixes the other end of the traction rope 5 to the frame of the vehicle.

[0022] The working principle and use process of the utility model are as follows: when the device is not in use, the cable protection gasket 21 and the lubricating pad layer 22 are rolled up in the rolling protection shell 2, the extrusion fastening plug block 24 is plugged into the connecting socket 12 of the adjacent mobile support base plate 1, and multiple mobile support base plates 1 are connected to each other. When laying cables manually, the staff places multiple mobile support base plates 1 on the ground and pulls the outermost mobile support base plate 1 to move. Under the action of traction, the cable protection gasket 21 and the lubricating pad layer 22 are gradually unfolded from the rolling protection shell 2, and the mobile support base plate 1 moves on the ground. Then the staff pulls the cable to move on the top of the cable protection gasket 21. When the cable is moved by means of a vehicle towing the movement, the outermost mobile support base plate 1 is fixed to the vehicle by means of the towing rope 5, and is unfolded by means of the vehicle towing device, and the unfolding of the device and the laying of the cable are performed simultaneously. The cable protection gasket 21 and the cable support roller 3 laid on the ground can prevent the cable from contacting the ground, thereby preventing the cable from being damaged by friction with the ground during the laying process. When the ground is flat, the mobile support base plate 1 is directly placed on the ground. When the ground is uneven, the staff drags the mobile support base plate 1 to a suitable position, and then uses the plug-in positioning rod 41 to pass through the hole of the limit connecting rod 4 and plug it into the ground, so that the mobile support base plate 1 cannot be flipped over.
