Description

Technical Field

[0001] The utility model relates to the technical field of cable loosening, in particular to a device for cable loosening. Background Art

[0002] During the cable laying construction, the power workers are generally required to control the cable to be detached from the cable drum and move it along a predetermined route to provide support for laying the cable in the corresponding position. At present, the cable drum is large in size, and the mass of the cable drum increases after the cable is rolled on the cable drum. Therefore, if the power workers want to control the cable to be output from the cable drum, they must use other devices to make the cable drum detach from the ground so that it can rotate under the action of external force to achieve the release of the cable.

[0003] At present, the equipment used to control the output of the cable drum is generally a lifting device. The cable of the lifting device is connected to the end of the central axis that passes through the cable drum. The lifting device controls the cable drum to rise under the action of the lifting device, and provides support for the cable drum to rotate under the action of external force. However, the cost of renting the lifting device every day is high, and the cable laying task is time-consuming, thus incurring a large cost for renting the lifting equipment.

[0004] In order to solve the above problems, devices for laying cables have appeared on the market, such as a cable laying device disclosed in a Chinese patent with patent announcement number CN219807620U, which includes a frame, a first clamping part and a clamping plate are respectively arranged at the edges of both sides of the frame, a second clamping part is also arranged between the first clamping part and the clamping plate, the second clamping part is close to the clamping plate, and the first clamping part and the second clamping part are used to clamp the cable reel; an adjustment mechanism is arranged between the first clamping part and the clamping plate to change the distance between the second clamping part and the first clamping part. According to the utility model, by changing the distance between the second clamping part and the first clamping part through the adjustment mechanism, when facing cable reels of different specifications, the second clamping part can be moved toward the first clamping part through the adjustment mechanism, so as to cooperate with the cable reel to clamp, and when it needs to be disengaged, the reverse operation is performed to disengage it, so as to assist in the laying of cables on the basis of solving the clamping problem of cable reels of different specifications. The device provided by the above patent can be used to release the cable, but the structure of the device is relatively complex, the size is large, and it is inconvenient to fold and store according to needs. Therefore, it is less practical for cable laying operations. Because when using the device provided by the above patent to release the cable, it is necessary to equip it with a transport vehicle to transport it to the construction site, and multiple power workers are required to place the cable drum on the device, which invisibly increases the cable laying cost and the labor intensity of the power workers.

[0024] The following is a further description with reference to the accompanying drawings and specific embodiments:

[0025] Example 1

[0026] The background technology records that the method of using a lifting device to control the cable drum 1 to leave the ground to provide support for the loosened cable is costly. It also records that the existing cable laying equipment is complex in structure and large in size, and requires a transport vehicle and manual labor to push the cable drum 1 to move to the cable laying equipment, which is less practical. Therefore, in order to solve the above problems, this embodiment provides the following technical solutions.

[0027] like Figure 1 , Figure 2 , Figure 5 As shown, the technical solution for releasing the cable includes a transverse axis 4, two sets of connecting components 3 and two legs 2. The two sets of connecting components 3 and the two legs 2 are matched one by one, and the connecting components 3 are hingedly arranged above the legs 2, and the connecting components 3 are sleeved on the transverse axis 4. When the above structure is used to support the cable drum 1, the transverse axis 4 is firstly set through the cable drum 1, and then the two sets of connecting components 3 are sleeved on the two ends of the transverse axis 4 respectively. In addition, holes are provided at both ends of the transverse axis 4, and a positioning pin 41 is provided at a certain hole. Under the action of the positioning pin 41, the position of the connecting component 3 relative to the transverse axis 4 can be limited, and the legs 2 are forced to rotate around the axis by adjusting the state of the connecting component 3, so that the inclined legs 2 and the transverse axis 4 gradually present a vertical state. During the rotation of the legs 2, the cable drum 1 is gradually lifted, so that the cable drum 1 rises and leaves the ground. After the cable drum 1 leaves the ground, the motor is installed on the support leg 2, and the driving wheel 5 is facing the cable drum 1. In addition, an anti-skid layer 51 is provided on the driving wheel 5, and the anti-skid layer 51 contacts the cable drum 1. When the motor is working, the driving wheel 5 is controlled to rotate, thereby driving the cable drum 1 to rotate slowly to achieve the release of the cable. The above-mentioned setting changes the current situation of using lifting equipment to lift the cable drum 1. At the same time, it has a simple structure, a small size, and can be disassembled and stored when not in use. Therefore, it is convenient for power workers to carry it to the construction site.

[0028] like Figure 3 , Figure 4As shown, in order to adjust the tilt angle of the leg 2, the connecting assembly 3 includes a connecting plate 33, a baffle 32 and an extrusion plate 35. The baffle 32 and the extrusion plate 35 are distributed on both sides of the connecting plate 33 and have the same height. The height of the baffle 32 is greater than that of the connecting plate 33. The tops of the baffle 32 and the connecting plate 33 are connected with a sleeve. The top of the extrusion plate 35 and the sleeve are both sleeved on the horizontal axis 4. The leg 2 is set as a "human" structure. A vertical bar hole 21 is set at the top of the leg 2. The lower end of the connecting plate 33 is hingedly set at the top of the leg 2. The lower ends of the baffle 32 and the extrusion plate 35 are lower than the upper end of the vertical bar hole 21. A threaded column 31 is penetrated at the bottom of the baffle 32. The threaded column 31 penetrates the vertical bar hole 21 and is threadedly inserted into the threaded hole 34 of the extrusion plate 35. At this time, the distance between the baffle 32 and the extrusion plate 35 is the smallest, and it fits the leg 2. After the extrusion plate 35 and the sleeve are both sleeved on the horizontal axis 4, the power worker holds the hexagonal wrench and inserts the end of the hexagonal wrench into the hexagonal groove at the end of the threaded column 31, so that the threaded column 31 can be driven to rotate by the hexagonal wrench, forcing the baffle 32 and the extrusion plate 35 to approach each other. In the process of the baffle 32 and the extrusion plate 35 approaching each other, the bottom of the extrusion plate 35 forces the leg 2 to rotate around the axis until the leg 2 is fitted with the baffle 32 and the extrusion plate 35. At this time, under the action of the baffle 32 and the extrusion plate 35, the leg 2 and the connecting plate 33 are stably connected, and the cable drum 1 is supported to be stably placed off the ground. In the process of the change of the inclination angle of the leg 2, the threaded column 31 always moves in the vertical bar hole 21.

[0029] like Figure 3 As shown, in order to facilitate the adjustment of the tilt angle of the leg 2 and to be able to transfer the cable drum 1 as needed, a universal wheel is hingedly provided at the bottom of the leg 2, and the universal wheel may be provided with a braking function. The universal wheel with a braking function has been widely used, so it will not be described in detail here.

[0030] Example 2

[0031] The background technology records that the method of using a lifting device to control the cable drum 1 to leave the ground to provide support for the loosened cable is costly. It also records that the existing cable laying equipment is complex in structure and large in size, and requires a transport vehicle and manual labor to push the cable drum 1 to move to the cable laying equipment, which is less practical. Therefore, in order to solve the above problems, this embodiment provides the following technical solutions.

[0032] like Figure 1 , Figure 2 , Figure 5As shown, the technical solution for releasing the cable includes a transverse axis 4, two sets of connecting components 3 and two legs 2. The two sets of connecting components 3 and the two legs 2 are matched one by one, and the connecting components 3 are hingedly arranged above the legs 2, and the connecting components 3 are sleeved on the transverse axis 4. When the above structure is used to support the cable drum 1, the transverse axis 4 is firstly set through the cable drum 1, and then the two sets of connecting components 3 are sleeved on the two ends of the transverse axis 4 respectively. In addition, holes are provided at both ends of the transverse axis 4, and a positioning pin 41 is provided at a certain hole. Under the action of the positioning pin 41, the position of the connecting component 3 relative to the transverse axis 4 can be limited, and the legs 2 are forced to rotate around the axis by adjusting the state of the connecting component 3, so that the inclined legs 2 and the transverse axis 4 gradually present a vertical state. During the rotation of the legs 2, the cable drum 1 is gradually lifted, so that the cable drum 1 rises and leaves the ground. After the cable drum 1 leaves the ground, the motor is installed on the support leg 2, and the driving wheel 5 is facing the cable drum. In addition, an anti-skid layer 51 is provided on the driving wheel 5, and the anti-skid layer 51 contacts the cable drum. When the motor is working, the driving wheel 5 is controlled to rotate, thereby driving the cable drum 1 to rotate slowly to achieve the release of the cable. The above-mentioned setting changes the current situation of using lifting equipment to lift the cable drum 1. At the same time, it has a simple structure, a small size, and can be disassembled and stored when not in use. Therefore, it is convenient for power workers to carry it to the construction site.

[0033] like Figure 3 , Figure 4 As shown, in order to adjust the tilt angle of the leg 2, the connecting assembly 3 includes a connecting plate 33, a baffle 32 and an extrusion plate 35. The baffle 32 and the extrusion plate 35 are distributed on both sides of the connecting plate 33 and have the same height. The height of the baffle 32 is greater than that of the connecting plate 33. The tops of the baffle 32 and the connecting plate 33 are connected with a sleeve. The top of the extrusion plate 35 and the sleeve are both sleeved on the horizontal axis 4. The leg 2 is set as a "human" structure. A vertical bar hole 21 is set at the top of the leg 2. The lower end of the connecting plate 33 is hingedly set at the top of the leg 2. The lower ends of the baffle 32 and the extrusion plate 35 are lower than the upper end of the vertical bar hole 21. A threaded column 31 is penetrated at the bottom of the baffle 32. The threaded column 31 penetrates the vertical bar hole 21 and is threadedly inserted into the threaded hole 34 of the extrusion plate 35. At this time, the distance between the baffle 32 and the extrusion plate 35 is the smallest, and it fits the leg 2. After the extrusion plate 35 and the sleeve are both sleeved on the horizontal axis 4, the power worker holds the hexagonal wrench and inserts the end of the hexagonal wrench into the hexagonal groove at the end of the threaded column 31, so that the threaded column 31 can be driven to rotate by the hexagonal wrench, forcing the baffle 32 and the extrusion plate 35 to approach each other. In the process of the baffle 32 and the extrusion plate 35 approaching each other, the bottom of the extrusion plate 35 forces the leg 2 to rotate around the axis until the leg 2 is fitted with the baffle 32 and the extrusion plate 35. At this time, under the action of the baffle 32 and the extrusion plate 35, the leg 2 and the connecting plate 33 are stably connected, and the cable drum 1 is supported to be stably placed off the ground. In the process of the change of the inclination angle of the leg 2, the threaded column 31 always moves in the vertical bar hole 21.

[0034] As Figure 3 shown, in order to facilitate the adjustment of the inclination angle of the outrigger 2 and to be able to transfer the cable drum 1 according to requirements, a universal wheel is hingedly provided at the bottom of the outrigger 2. The universal wheel can be provided with a braking function. The universal wheel with a braking function has been widely used, so it will not be described in detail here.

[0035] As Figure 5 、 Figure 6 shown, in order to enable the driving wheel 5 to control the rotation of the cable drum 1, that is, to make the driving wheel 5 in frictional contact with the cable drum 1, a sleeve plate 52 is fixedly provided on the side of the motor. The sleeve plate 52 is arranged in a U-shaped structure, and an end plate 53 is detachably provided at the opening. An internally threaded tube 54 is provided on the end plate 53. The outrigger 2 passes through the space formed by the sleeve plate 52 and the end plate 53. An adjusting screw 22 is provided on the side of the outrigger 2. The adjusting screw 22 is threadedly penetrated through the internally threaded tube 54. By rotating the adjusting screw 22, the motor can be controlled to move along the length direction of the outrigger 2, and at the same time, the driving wheel 5 is driven to move, increasing the pressure between the driving wheel 5 and the cable drum 1, deforming the anti-slip layer 51, and cooperating with the anti-slip layer 51 to increase the friction between the driving wheel 5 and the cable drum 1, so as to drive the cable drum 1 to rotate during the rotation of the driving wheel 5.

[0036] The above is only the preferred embodiment of the present invention and is not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
