Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of power construction auxiliary equipment, in particular to a cable laying device. BACKGROUND

[0002] In the process of cable laying construction, when the cable needs to be pulled through the channel such as pipe and bridge, the direct friction between the outer wall of the cable and the edge of the channel port will cause damage to the cable insulation layer, significantly increase the pulling resistance and low construction efficiency.

[0003] Especially in high-voltage cable construction, the sharp edge of the channel port is easy to scratch the surface of the cable, and slight damage may cause serious safety hazards. At the same time, the excessive friction resistance not only needs to configure larger power traction equipment, but also is easy to cause the cable to twist and deform. In addition, it is difficult for artificial to accurately adjust the cable direction in real time, and the frequent sticking phenomenon will also affect the overall construction progress.

[0004] Therefore, it is urgent to design a cable laying device to reduce the cable friction damage, reduce the cable pulling resistance and improve the construction efficiency, and solve the technical bottleneck of the traditional construction method. SUMMARY

[0005] In view of the above background technology, the embodiment of the present application provides a cable laying device which can reduce the resistance when the cable is pulled, avoid the cable being scratched by the edge of the channel port, and further reduce the damage to the cable.

[0006] The embodiment of the present application provides a cable laying device, which comprises:

[0007] A guide assembly, the guide assembly comprises a bracket and a roller arranged on the bracket and used for guiding the cable to pass through the cable channel port;

[0008] A tensioning assembly, the tensioning assembly comprises a pulling component connected with the bracket, and the pulling component is used for pulling the bracket towards the cable channel port to make the bracket abut against the end face of the cable channel port.

[0009] In some embodiments, the bracket comprises an end plate and two side plates fixedly connected to the end plate, a roller is rotatably connected between the two side plates through a shaft, and the pulling component is connected to the two side plates.

[0011] In some embodiments, the pulling component is an adjustable-length pull rod, which includes a sleeve and a screw, and the sleeve is provided with a thread adapted to the screw.

[0012] In some embodiments, the pull rod further includes an intermediate rod, both ends of which are rotatably connected to the sleeve, and the rotation axis of the sleeve is collinear with the central axis of the intermediate rod.

[0014] In some embodiments, the pulling component is a cable, and the tensioning assembly further includes a tensioner connected to the cable and used to tighten the cable.

[0015] In some embodiments, the roller includes a cylindrical roller body and annular flanges disposed at both ends of the cylindrical roller body, the annular flanges being connected to the outer peripheral surface of the cylindrical roller body through a tapered transition surface.

[0016] In some embodiments, the side of the bracket away from the roller is connected to a gripping cylinder, the cylinder including a first semi-circular plate fixedly connected to the bracket and a second semi-circular plate detachably connected to the bracket.

[0030] In view of the shortcomings or deficiencies mentioned in the background art, the present application provides a cable delivery device that can reduce the resistance when pulling the cable, avoid the cable being scratched by the edge of the channel port, and thus reduce cable damage.

[0031] See Figures 1 to 5 As shown, this application provides a cable laying device, including:

[0032] The guide assembly includes a bracket 1 and a roller 3 disposed on the bracket 1 for guiding the cable through the cable channel opening 2;

[0033] The tensioning assembly includes a pulling component 4 connected to the bracket 1. The pulling component 4 is used to pull the bracket 1 toward the cable channel opening 2 so that the bracket 1 abuts and is fixed to the end face of the cable channel opening 2.

[0034] The cable laying device of this application embodiment is provided with a guiding component and a tensioning component. The guiding component includes a bracket 1 and a roller 3 rotatably connected to the bracket 1. The tensioning component includes a pulling component 4 fixedly connected to the bracket 1. By pulling with the pulling component 4, the bracket 1 can be cleverly abutted and fixed at any cable channel opening 2 in the cable trench.

[0035] In use, the pulling component 4 pulls the bracket 1 towards the cable channel opening 2, causing the bracket 1 to abut and fix against the end face of the cable channel opening 2. Then, the rollers 3 on the bracket 1 guide the cable passing through the cable channel opening 2. Specifically, the cable extends upwards around the rollers 3. When the cable is pulled, the rollers 3 contact the cable, and the cable no longer contacts the edge of the cable channel port, thereby reducing the resistance when pulling the cable and reducing cable damage.

[0036] It should be noted that in this embodiment, the bracket 1 equipped with rollers 3 is temporarily fixed to the end face of the cable channel opening 2 by abutment. By adjusting the positions of the bracket 1 and the pulling component 4, cable can be installed at any position within the auxiliary cable trench. For example, the pulling component 4 can be a pull rod or a cable, which can easily pass through the cable channel opening 2 to pull the bracket 1 towards the cable channel opening 2, so that the bracket 1 is abutted and fixed to the end face of the cable channel opening 2.

[0037] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a cable laying device. The support 1 of the cable laying device includes an end plate 11 and two side plates 12 fixedly connected to the end plate 11.

[0038] The bracket 1 in this embodiment includes an end plate 11 and two side plates 12. The two side plates 12 are parallel to each other and spaced apart. The two side plates 12 are fixedly connected to the end plate 11 by welding. The shaft is bolted, and the bolt passes through the two side plates 12 and the roller 3. A pulling member 4 is fixedly connected to each of the two side plates 12. By pulling simultaneously with the pulling members 4 on both sides, the end faces of the two side plates 12 can be simultaneously pressed against the end face of the cable channel opening 2, thereby facilitating the guidance of the cable passing through the cable channel opening 2 by the roller 3.

[0039] In some alternative embodiments: see Figures 1 to 5 As shown in the figure, this application embodiment provides a cable delivery device. The pulling component 4 of the cable delivery device is detachably connected to the bracket 1. A baffle 5 for abutting the cable channel opening 2 is installed at the end of the pulling component 4 away from the bracket 1.

[0040] In this embodiment of the application, the traction component 4 and the bracket 1 are connected by bolts. An anchor rod is fixedly connected to the end of the traction component 4. The anchor rod has a mounting hole for mounting bolts. At the same time, the side plate 12 also has a mounting hole for mounting bolts. The anchor rod and the side plate 12 are fixedly connected by mounting bolts.

[0041] In addition, a baffle 5 is installed at the end of the pulling component 4 away from the bracket 1. The pulling component 4 can be a pull rod or a cable. When the bracket 1 is abutted and fixed on the end face of the cable channel 2 on one side, the pulling component 4 can pass through the cable channel 2 on the side in advance and abutted and fixed on the end face of the cable channel 2 on the other side using the baffle 5. The baffle 5 can act as a reaction seat to provide a reaction force to tighten the bracket 1.

[0042] In some alternative embodiments: see Figures 1 to 5 As shown in the figure, this application embodiment provides a cable delivery device. The pulling component 4 of the cable delivery device is a pull rod with adjustable length. The pull rod includes a sleeve 41 and a screw 42. The sleeve 41 is provided with a thread that is adapted to the screw 42.

[0043] In this embodiment, the pulling component 4 is an adjustable length pull rod. The pull rod includes a sleeve 41 and a screw 42. The screw 42 is threadedly connected to the sleeve 41, allowing the sleeve 41 and the screw 42 to rotate relative to each other. This allows control over the length of the screw 42 extending out of the sleeve 41, facilitating the pull rod's passage through cable channels of different lengths.

[0044] In some alternative embodiments: see Figures 1 to 5 As shown in the figure, this application embodiment provides a cable laying device. The cable laying device's pull rod also includes an intermediate rod 43. Both ends of the intermediate rod 43 are rotatably connected to sleeves 41, and the rotation axis of the sleeves 41 is collinear with the central axis of the intermediate rod 43.

[0045] The pull rod in this embodiment includes an intermediate rod 43. Both ends of the intermediate rod 43 are coaxially rotatably connected to sleeves 41. Screws 42 are threadedly connected to the sleeves 41 at both ends. One end of the screw 42 is connected to the side plate 12 of the bracket 1 by a bolt. The other end of the screw 42 passes through the baffle 5 and is threadedly connected to a nut to prevent the baffle 5 from detaching.

[0046] For example, the sleeve 41 and the screw 42 are rotated relative to each other. After the screw 42 extends out of the sleeve 41 to a suitable length, the pull rods on both sides are passed through the cable channel. Then, one end of the pull rod, the screw 42, is fixedly connected to the side plate 12 with bolts. Finally, a baffle 5 and a nut are installed on the other end of the pull rod, the nut is rotated to make the baffle 5 abut against the end face of the cable channel opening 2 on one side, and at the same time, the side plate 12 on the other side abuts and is fixed against the end face of the cable channel opening 2 on the other side.

[0047] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a cable delivery device. The outer periphery of the sleeve 41 of the cable delivery device is provided with a protrusion 411, which is used to apply torque to make the sleeve 41 rotate around its central axis.

[0048] In this embodiment, the sleeve 41 is provided with a protrusion 411 on its outer periphery. The protrusion 411 is a lever or handle and is fixed by welding. The protrusion 411 facilitates the application of torque to make the sleeve 41 rotate around its central axis, thereby causing the sleeve 41 and the screw 42 to rotate relative to each other, which facilitates the control of the length of the screw 42 extending out of the sleeve 41.

[0049] In some alternative embodiments: see Figures 1 to 5 As shown in the figure, this application provides a cable laying device. The pulling component 4 of the cable laying device is a cable, and the tensioning assembly also includes a tensioner connected to the cable and used to tighten the cable.

[0050] In this embodiment, the pulling component 4 can be a cable. One end of the cable is fixedly connected to the bracket 1 and passes through the cable channel, then is fixedly connected to one end of the tensioner. The other end of the tensioner is fixedly connected to an external ground fixing base. The tensioner can tighten the cable, causing the bracket 1 to abut and be fixed to the end face of the cable channel opening 2. For example, the tensioner can be a wire rope tensioner or a stainless steel turnbuckle.

[0051] In some alternative embodiments: see Figures 1 to 5 As shown, this application embodiment provides a cable delivery device. The roller 3 of the cable delivery device includes a cylindrical roller body 31 and annular flanges 32 disposed at both ends of the cylindrical roller body. The annular flanges 32 are connected to the outer peripheral surface of the cylindrical roller body 31 through a conical transition surface 33.

[0052] The roller 3 in this embodiment includes a cylindrical roller body 31 and annular flanges 32 at both ends of the cylindrical roller body. The cylindrical roller body 31 facilitates cable routing, and the annular flanges 32 prevent the cable from rubbing against the side plates 12 on both sides of the support 1, ensuring that the cable is always within the effective working area of ​​the roller 3. The tapered transition surface 33 between the annular flanges 32 and the cylindrical roller body 31 can guide the cable to smoothly enter the working surface of the cylindrical roller body 31, reducing the fluctuation of traction force.

[0053] For example, in some embodiments, a roller 3 with a spacing between the two annular flanges 32 smaller than the diameter of the cable channel opening 2 can be used to limit the axial movement space of the cable on the roller 3, effectively preventing the cable from directly scraping against the port of the cable channel.

[0054] In some alternative embodiments: see Figures 1 to 5 As shown in the figure, this application embodiment provides a cable delivery device. The support 1 of the cable delivery device is connected to a cylinder 6 for holding on the side away from the roller 3. The cylinder 6 includes a first semi-circular arc plate 61 fixedly connected to the support 1 and a second semi-circular arc plate 62 detachably connected to the support 1.

[0055] In this embodiment, a cylindrical body 6 is connected to the side of the bracket 1 away from the roller 3. The cylindrical body 6 can be gripped, facilitating the bolt connection between the bracket 1 and the pulling component 4. In this embodiment, for ease of processing, the cylindrical body 6 is divided into two halves, including a first semi-circular arc plate 61 and a second semi-circular arc plate 62. The first semi-circular arc plate 61 is welded and fixed to the end plate 11 of the bracket 1, and the second semi-circular arc plate 62 is detachably connected to the first semi-circular arc plate 61. The first semi-circular arc plate 61 and the second semi-circular arc plate 62 can form a complete force-bearing ring structure, ensuring gripping strength while facilitating disassembly and maintenance.

The second semi-circular plate 62 is welded and fixed to the movable plate 7. The first semi-circular plate 61 and the second semi-circular plate 62 are joined to form a complete force-bearing ring structure, thereby ensuring the grip strength. By disassembling the movable plate 7, the second semi-circular plate 62 can be separated from the first semi-circular plate 61, which facilitates disassembly and maintenance.
