Description

Technical Field

[0001] The utility model belongs to the technical field of cable laying devices, and specifically relates to a cable laying device. Background Technique

[0002] When building a road or a building, the power distribution will be planned in advance, so that the circuit pipes are laid on the road surface or around the building. When laying cables, a laying device is needed to pass the cables from one end of the manhole to the manhole at the other end.

[0003] Currently, in the prior art, when laying cables, the cables need to be passed through the pipes of one manhole to the manhole at the other end. Usually, steel wires are used to pull the cables from one end to the other end. During this process, the steel wires need to be fixed to the ends of the cables and then pulled back to the manhole at the other end.

[0004] Moreover, the surface of the cable is made of insulating material. During the process of pulling the steel wire, as the length of the cable entering the pipe increases, the contact area between the cable and the pipe also increases. Thus, a greater pulling force is required to pull the cable. As the pulling force increases, the frictional force between the cable and the pipe increases, and the connection between the cable and the steel wire is likely to become detached. Therefore, a cable laying device is proposed to address the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background technique, the utility model proposes a cable laying device.

[0010] Preferably, a plurality of transverse threaded holes are formed in the side wall of the wire locking buckle; a second fixing bolt is threadedly connected to the inner side wall of the transverse threaded hole.

[0011] The beneficial effects of the present invention:

[0012] 1. The present invention provides a cable laying device. By setting the cable fixing component, the staff places the cable inside the wire locking buckle, then closes the wire locking buckle and fixes it with the first fixing bolt, and the spikes will insert into the cable, so as to bite the cable inside the wire locking buckle. Through multiple spikes, the fixing effect of the wire locking buckle on the cable is effectively increased. Then, the wire locking buckle is placed inside the wire slot, and the wire locking buckle is fixed inside the wire slot through the limiting component. The traction nut provided at one end of the wire threading cylinder can be used to fix the steel wire. By setting the ball bearings, the friction between the wire threading cylinder and the pipeline is effectively reduced, so that the sliding friction between the pipeline and the wire threading cylinder becomes the rolling friction between the ball bearings and the pipeline. By reducing the friction with the pipeline, the smoothness of the equipment moving inside the pipeline is effectively increased, and at the same time, the pulling force required to pull the cable is reduced, the situation of the steel wire and the cable falling off is reduced, and accidents are reduced.

[0013] 2. The utility model provides a cable laying device. Through the arranged limiting device, when the wire locking buckle is inserted into the wire inserting groove, the wire locking buckle will squeeze the arc surface of the limiting pin. As the wire locking buckle is continuously squeezed, the limiting pin will be pushed into the fixing groove. Since the magnet and the magnetic sheet are made of the same material, which is a magnet, and there is a repulsive force between the magnets, after the wire locking buckle is completely inserted into the wire inserting groove, the repulsive force between the magnetic sheet and the magnet will push the limiting pin out of the fixing groove. The protruding part of the fixing groove can block the side wall of the wire locking buckle, thereby completing the fixation of the wire locking buckle. The wire locking buckle is fixed inside the wire inserting groove. Through the arranged limiting component, the situation that the wire locking buckle disengages from the inside of the wire inserting groove is effectively reduced, thereby effectively improving the stability of the device and reducing the occurrence of accidents.

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0024] Specific examples are given below.

[0025] Please refer to Figure 1 - Figure 6, the present utility model provides a cable laying device, including a wire threading cylinder 1, a cable fixing component, a limiting component and a disassembly component; an insertion groove 13 is opened on the side wall of the wire threading cylinder 1; a cable fixing component is installed on the inner side wall of the insertion groove 13; a limiting component is installed on the inner side wall of the insertion groove 13; multiple groups of grooves 11 are opened on the side wall of the wire threading cylinder 1; the grooves 11 are arranged in a circular array; a ball 12 is rotatably connected to the inner side wall of the groove 11; a threaded hole 14 is opened at the end of the wire threading cylinder 1; a traction nut 15 is threadedly connected to the inner side wall of the threaded hole 14. The cable fixing component includes a wire locking buckle 2, a barb 21, a vertical threaded hole 22, and a first fixing bolt 23; a wire locking buckle 2 is installed on the inner side wall of the insertion groove 13; the wire locking buckle 2 is of a two-piece type and is hinged; multiple groups of barbs 21 are fixedly connected to the inner side wall of the wire locking buckle 2; a pair of vertical threaded holes 22 are opened on the side wall of the wire locking buckle 2; a first fixing bolt 23 is threadedly connected to the inner side wall of the vertical threaded hole 22. During operation, when laying a cable, it is necessary to pass the cable through the pipeline of one manhole into the manhole at the other end. Usually, a steel wire is used to pull the cable from one end to the other end. During this process, the steel wire needs to be fixed to the end of the cable, and the surface of the cable is made of insulating material. As the length of the cable entering the pipeline increases during the pulling of the steel wire, the contact area between the cable and the pipeline also increases, and thus a greater pulling force is required to pull the cable. As the pulling force increases, the friction between the cable and the pipeline increases, and the connection between the cable and the steel wire is likely to come off. Through the provided cable fixing component, the staff places the cable inside the wire locking buckle 2, then closes the wire locking buckle 2 and fixes it with the first fixing bolt 23, and the barbs 21 will insert into the cable, thereby biting the cable inside the wire locking buckle 2. Through multiple barbs 21, the fixing effect of the wire locking buckle 2 on the cable is effectively increased. Then, the wire locking buckle 2 is placed inside the insertion groove 13, and the wire locking buckle 2 is fixed inside the insertion groove 13 through the limiting component. The traction nut 15 provided at one end of the wire threading cylinder 1 can be used to fix the steel wire. Through the provided balls 12, the friction between the wire threading cylinder 1 and the pipeline is effectively reduced, making the sliding friction between the pipeline and the wire threading cylinder 1 become the rolling friction between the balls 12 and the pipeline. By reducing the friction with the pipeline, the smoothness of the device moving inside the pipeline is effectively increased, while reducing the pulling force required to pull the cable, reducing the situation of the steel wire and the cable coming off, and reducing the occurrence of accidents.

[0026] Further, as Figure 2 - Figure 6As shown, the limiting component includes a fixing groove 3, a magnetic sheet 31, a limiting pin 32, a mounting groove 33, and a magnet 34; multiple groups of fixing grooves 3 are provided on the inner sidewall of the wire slot 13; the magnetic sheet 31 is fixedly connected to the inner sidewall of the fixing groove 3; the limiting pin 32 is slidably connected to the inner sidewall of the fixing groove 3; a mounting groove 33 is provided on the sidewall of the limiting pin 32; the magnet 34 is installed on the inner sidewall of the mounting groove 33; at the end of the fixing groove 3, during operation, after the cable locking buckle 2 that has been fixed is inserted into the wire slot 13, it is necessary to fix the locking buckle 2 to reduce the separation of the wire threading cylinder 1 and the locking buckle 2. Through the provided limiting device, when the locking buckle 2 is inserted into the wire slot 13, the locking buckle 2 will squeeze the arc surface of the limiting pin 32. As the locking buckle 2 is continuously squeezed, the limiting pin 32 will be pushed into the fixing groove 3. Since the magnet 34 and the magnetic sheet 31 are made of the same material, which is a magnet, and there is a repulsive force between the magnets, after the locking buckle 2 is completely inserted into the wire slot 13, the repulsive force between the magnetic sheet 31 and the magnet 34 will push the limiting pin 32 out of the fixing groove 3. The protruding part of the fixing groove 3 can block the sidewall of the locking buckle 2, thereby completing the fixation of the locking buckle 2 and fixing the locking buckle 2 inside the wire slot 13. Through the provided limiting component, the situation where the locking buckle 2 disengages from the inside of the wire slot 13 is effectively reduced, thereby effectively improving the stability of the device and reducing accidents.

[0027] Further, as Figure 3 - Figure 6 shown, the disassembly component includes a connection hole 4, a disassembly rope 41, and a connection column 42; multiple groups of connection holes 4 are provided on the inner sidewall of the threaded hole 14; the connection column 42 is rotatably connected to the end of the traction nut 15; the disassembly rope 41 is fixedly connected to the middle of the connection column 42; one end of the disassembly rope 41 is fixedly connected to the middle of the connection column 42, and the other end is fixedly connected to the sidewall of the magnet 34. During operation, after the cable is threaded from one end to the other end, it is necessary to remove the cable from the inside of the wire slot 13 for cable connection. Through the provided disassembly component, the staff unscrews the traction nut 15. After unscrewing the traction nut 15 and pulling the traction nut 15, a certain distance of the disassembly rope 41 is pulled out. When the disassembly rope 41 is pulled out, the limiting pin 32 will be pulled into the fixing groove 3. At this time, the limiting pin 32 will not limit the locking buckle 2, and then the wire threading cylinder 1 and the locking buckle 2 can be separated. Then, the traction nut 15 is screwed back to its original position. Under the action of the repulsive force, the limiting pin 32 will be pushed out of the fixing groove 3. Through the provided disassembly component, the staff can remove the locking buckle 2 from the inside of the wire slot 13 while removing the traction rope, which effectively facilitates the separation of the locking buckle 2 by the staff and increases the convenience of the device.

[0028] Further, as Figure 3 and Figure 5As shown, a plurality of cylindrical grooves 5 are formed in the side wall of the thread-locking buckle 2; a roller 51 is rotatably connected to the inner side wall of the cylindrical groove 5; the roller 51 is in contact with the inner side wall of the wire slot 13. During operation, after the device is placed in the cable pipe, when the staff is threading the wire, the wire will rotate during the threading process. As the wire rotates, the wire will be subjected to a certain torsional force, which will cause the thread-locking buckle 2 to rotate inside the wire slot 13. By providing the roller 51, the contact area between the thread-locking buckle 2 and the inner side wall of the wire slot 13 during rotation is effectively reduced, thereby improving the smoothness of the rotation of the thread-locking buckle 2. At the same time, the friction between parts is reduced, the wear between devices is reduced, and the service life of the device is improved.

[0029] Further, as Figure 3 and Figure 5 shown, a plurality of transverse threaded holes 6 are formed in the side wall of the thread-locking buckle 2; a second fixing bolt 61 is threadedly connected to the inner side wall of the transverse threaded hole 6. During operation, by providing a plurality of second fixing bolts 61 in the middle of the thread-locking buckle 2, after the cable is fixed inside the thread-locking buckle 2, through the second fixing bolts 61 provided in the middle and in cooperation with the first fixing bolts 23, the transverse and longitudinal fixation of the thread-locking buckle 2 is achieved, thereby effectively increasing the fixing effect on the thread-locking buckle 2, improving the fixing stability of the cable of the thread-locking buckle 2, effectively increasing the fixing effect of the device, and reducing the situation where the cable falls off from inside the thread-locking buckle 2.

[0030] Working principle: When laying cables, the cable needs to be passed through the pipeline of one manhole into the manhole at the other end. The cable is pulled from one end to the other by using a steel wire. During this process, the steel wire needs to be fixed at the end of the cable, and the surface of the cable is made of insulating material. As the length of the cable entering the pipeline increases during the pulling of the steel wire, the contact area between the cable and the pipeline also increases, and then a greater pulling force is required to pull the cable. As the pulling force increases, the frictional force between the cable and the pipeline increases, and the connection between the cable and the steel wire is prone to falling off. Through the provided cable fixing component, the staff places the cable inside the wire locking buckle 2, then closes the wire locking buckle 2 and fixes it with the first fixing bolt 23. Moreover, the spikes 21 will insert into the cable, thereby biting the cable inside the wire locking buckle 2. Through multiple spikes 21, the fixing effect of the wire locking buckle 2 on the cable is effectively increased. Then, the wire locking buckle 2 is placed inside the wire slot 13, and the wire locking buckle 2 is fixed inside the wire slot 13 through the limiting component. The traction nut 15 provided at one end of the wire threading cylinder 1 can be used to fix the steel wire. The provided ball 12 effectively reduces the frictional force between the wire threading cylinder 1 and the pipeline, changing the sliding friction between the pipeline and the wire threading cylinder 1 into the rolling friction between the ball 12 and the pipeline. By reducing the frictional force with the pipeline, the smoothness of the equipment moving inside the pipeline is effectively increased, while reducing the pulling force required to pull the cable, reducing the situation of the steel wire and the cable falling off, and reducing the occurrence of accidents. After inserting the fixed cable wire locking buckle 2 into the wire slot 13, it is necessary to fix the wire locking buckle 2 to reduce the situation of the wire threading cylinder 1 and the wire locking buckle 2 separating. Through the provided limiting device, when the wire locking buckle 2 is inserted into the wire slot 13, the wire locking buckle 2 will squeeze the arc surface of the limiting pin 32. As the wire locking buckle 2 is continuously squeezed, the limiting pin 32 will be pushed into the fixing slot 3. Since the material of the magnet 34 and the magnetic sheet 31 is the same, both are magnets, and there is a repulsive force between the magnets. After the wire locking buckle 2 is completely inserted into the wire slot 13, the repulsive force between the magnetic sheet 31 and the magnet 34 will push the limiting pin 32 out of the fixing slot 3. The protruding part of the fixing slot 3 can block the side wall of the wire locking buckle 2, thereby completing the fixation of the wire locking buckle 2 and fixing the wire locking buckle 2 inside the wire slot 13. Through the provided limiting component, the situation of the wire locking buckle 2 detaching from the inside of the wire slot 13 is effectively reduced, thereby effectively improving the stability of the equipment and reducing the occurrence of accidents. After threading the cable from one end to the other end, it is necessary to take out the cable from the inside of the wire slot 13 for cable connection. Through the provided disassembly component, the staff unscrews the traction nut 15. After unscrewing the traction nut 15 and pulling the traction nut 15, a certain distance of the disassembly rope 41 will be pulled out. When the disassembly rope 41 is pulled out, the limiting pin 32 will be pulled into the fixing slot 3. At this time, the limiting pin 32 will not limit the wire locking buckle 2, and then the wire threading cylinder 1 and the wire locking buckle 2 can be separated. Then, the traction nut 15 is screwed back to its original position, and under the action of the repulsive force, the limiting pin 32 will be pushed out of the fixing slot 3.Through the provided disassembly component, while the staff removes the towing rope, the wire locking buckle 2 can be taken out from the inside of the wire slot 13, effectively facilitating the separation of the wire locking buckle 2 by the staff and increasing the convenience of the device. After the device is placed into the cable pipe, when the staff threads the wire, the wire will rotate during the threading process. As the wire rotates, the wire will be subjected to a certain torsional force, which will cause the wire locking buckle 2 to rotate inside the wire slot 13. Through the provided roller 51, the contact area between the wire locking buckle 2 and the inner side wall of the wire slot 13 during rotation is effectively reduced, thereby improving the smoothness of the rotation of the wire locking buckle 2. At the same time, the friction between parts is reduced, the wear between devices is reduced, and the service life of the device is increased. By arranging multiple groups of second fixing bolts 61 in the middle of the wire locking buckle 2, after the cable is fixed inside the wire locking buckle 2, through the second fixing bolts 61 arranged in the middle and in cooperation with the first fixing bolts 23, the horizontal and vertical fixation of the wire locking buckle 2 is achieved, effectively increasing the fixation effect on the wire locking buckle 2, thereby improving the fixation stability of the cable by the wire locking buckle 2, effectively increasing the fixation effect of the device, and reducing the situation where the wire falls off from inside the wire locking buckle 2.,
