Description

Technical Field

[0001] This invention relates to the field of line installation technology, and more specifically to a line laying device based on line installation and maintenance. Background Technology

[0002] In the laying and installation of overhead lines, such as high-voltage transmission lines and urban power distribution networks, the laying of cables or conductors is a key construction step. Track-mounted cable laying frames are widely used as cable reel support equipment when laying cables under tension or by manual traction.

[0003] Traditional track-mounted cable laying frames are usually placed directly on the ground. In field operations such as pole erection and line extension, the construction site is often uneven, making it difficult to quickly level the cable laying frame. To ensure the cable reel is level, construction workers often need to place stones or wooden boards under the track, which is time-consuming, labor-intensive, and has poor stability. In addition, the cable reel on the cable laying frame is also placed horizontally, which means that when pushing the cable reel to roll for cable laying, a large force is required to overcome the static inertia of the cable reel, which is quite strenuous. Therefore, we propose a cable laying device based on line installation and maintenance. Summary of the Invention

[0004] The purpose of this invention is to provide a cable laying device based on line installation and maintenance, in order to solve the problems mentioned in the background art, such as the inconvenience of adjusting the level of the existing track-type cable laying frame, and the inconvenience of tilting it to overcome the static inertia when laying cables, and the problem that the cable reel moves along the axial direction of the support roller during cable laying.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a cable laying device based on line installation and maintenance, comprising:

[0006] Two tracks are arranged side by side, with through grooves running through the inner side of the tracks, and support rollers are rotatably installed at both ends of the inner side of the through grooves;

[0007] A cable reel is mounted on the supporting roller;

[0008] A limiting component is disposed on one side wall of the track to limit the end of the cable reel;

[0009] The mounting block is fixed to the middle of the inner side of the through groove, and two symmetrically arranged threaded cylinders are rotatably mounted on the side wall of the mounting block;

[0010] An adjustment component is slidably disposed inside the mounting block and extends through one end face of the track, so as to cooperate with one of the threaded cylinders during adjustment to drive rotation;

[0011] A support block assembly is mounted on the threaded cylinder, and a support foot is provided at the lower end of the support block assembly.

[0012] Preferably, the adjusting assembly includes an adjusting rod, a protrusion, and an inner groove. The adjusting rod is slidably installed on the inner side of the mounting block, and the outer surface of the adjusting rod protrudes outward to form a protrusion. The inner side of the threaded cylinder is provided with an adjusting groove structure that cooperates with the protrusion, and one end face of the adjusting rod is provided with an inner groove.

[0013] Preferably, the adjusting groove structure includes a mating groove and a guide groove. The mating groove is opened at one end of the inner wall of the threaded cylinder, and a guide groove is provided at one end of the mating groove. The guide groove is trumpet-shaped.

[0014] Preferably, the two ends of the protrusion are serrated.

[0015] Preferably, the support block assembly includes a threaded sleeve, a support block, and a fixing rod. The threaded sleeve is fitted onto the threaded cylinder through a threaded portion. The support block is rotatably mounted on the lower end of the threaded sleeve, and the other end of the support block is rotatably engaged with the support leg. The fixing rod is fixed to the lower end of the inner side of the through groove, and a guide hole that engages with the fixing rod is provided along the long side of the inner side of the support block.

[0016] Preferably, the limiting component includes a fixing block, a spring, a cylinder, a toothed block, a connecting rod, and a limiting roller. The fixing block is fixed to one side wall of the track. The cylinder is slidably installed inside the fixing block, and the lower end of the cylinder has a spring. The upper end of the outer wall of the cylinder is provided with a toothed block that cooperates with the fixing block. The connecting rod is fixed to the cylinder, and one end of the connecting rod is rotatably provided with a limiting roller that contacts the cable reel.

[0017] Preferably, the fixing block has an installation groove on its inner side, and the upper end of the inner side of the installation groove is fixed with a toothed groove that mates with the toothed block.

[0018] Preferably, the toothed blocks are evenly distributed in multiples along the circumference of the cylinder.

[0019] Preferably, the inner edge of the through groove is slidably connected with an adjusting nut for limiting the track via a threaded connection.

[0020] Preferably, one end of the track is provided with an inclined surface for the cable reel to roll.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] (1) The present invention is equipped with a threaded cylinder, mounting block, support block assembly, adjustment assembly and support feet, which avoids the inconvenience of adjusting the track tilt of the track-type cable feeding frame so that the cable reel can roll. The structure of this device is simple. The threaded cylinder can be driven to rotate at the end of the track by the adjustment assembly to support the bottom of the track. It is relatively labor-saving and easy to level or adjust the track to make it tilt. The operation is simple and greatly improves the ease of rotation and rolling of the cable reel during cable feeding, and increases the practicality of the device.

[0023] (2) By setting a fixed block, spring, cylinder, toothed block, connecting rod and limiting roller, the long shaft of the supporting roller is avoided. The outer rings at both ends of the cable reel will move along the axial direction of the supporting roller when placed. This device can effectively limit the position of the outer ring at the end of the cable reel, and can effectively maintain the stability of the position of the cable reel when rolling and releasing the cable. Moreover, the position of the limiting roller can be adjusted according to the position of the end of the cable reel, which increases the practicality of the device. Attached Figure Description

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-9 This invention provides a technical solution: a cable laying device based on line installation and maintenance, comprising:

[0036] Two parallel tracks 1 are provided, with through grooves running through the inner side of each track 1, and support rollers 4 are rotatably installed at both ends of the through grooves.

[0037] Cable reel 5 is mounted on support roller 4;

[0038] Limiting component 7 is provided on one side wall of track 1 to limit the end of cable reel 5;

[0039] Because the support roller 4 has a large axial length, it is easier for the outer ring of the cable reel 5 to be pushed onto the support roller 4 along the inclined surface 6 when it is first placed. At the same time, the large length of the support roller 4 can also accommodate different widths of the outer ring of the cable reel 5. During cable laying, in order to prevent the outer ring of the cable reel 5 from moving back and forth in the axial direction of the support roller 4, the limiting component 7 blocks the outer ring of the cable reel 5, thereby providing stability to the position of the cable reel 5 during cable laying.

[0040] Mounting block 9 is fixed in the middle of the inner side of the through groove, and two threaded cylinders 8 are symmetrically arranged and rotatably mounted on the side wall of mounting block 9;

[0041] The adjustment component is slidably disposed inside the mounting block 9 and passes through one end face of the track 1 so as to cooperate with one of the threaded cylinders 8 to drive rotation during adjustment;

[0042] The support block assembly 11 is easy to move, so that the track 1 can be supported by the support block assembly 11. It is convenient to adjust the track 1 to be horizontal or tilted during placement. In turn, when the cable reel 5 is unloaded, it is convenient to make the cable reel 5 roll on the support roller 4, thereby improving the unloading effect of the cable reel 5.

[0043] The support block assembly 11 is mounted on the threaded cylinder 8, and the lower end of the support block assembly 11 is provided with a support foot 10.

[0044] The support block assembly 11 can be moved to support the track 1 by means of the threaded drive of the threaded cylinder 8.

[0045] Preferably, the adjustment assembly includes an adjustment rod 12, a protrusion 13 and an inner groove 14. The adjustment rod 12 is slidably installed on the inner side of the mounting block 9, and the outer surface of the adjustment rod 12 protrudes outward to form a protrusion 13. The inner side of the threaded cylinder 8 is provided with an adjustment groove structure that cooperates with the protrusion 13, and one end face of the adjustment rod 12 is provided with an inner groove 14.

[0046] It is easy to insert an external hex wrench into the inner side of the inner groove 14, thereby driving the adjusting rod 12 to rotate and drive the threaded cylinder 8 to rotate. The operation is simple and easy to adjust with little effort.

[0047] Preferably, the adjusting groove structure includes a mating groove 151 and a guide groove 152. The mating groove 151 is opened at one end of the inner wall of the threaded cylinder 8, and a guide groove 152 is provided at one end of the mating groove 151. The guide groove 152 is trumpet-shaped.

[0048] This allows the protrusion 13 to pass better through the guide groove 152 and be inserted into the inner side of the mating groove 151, thereby driving the threaded cylinder 8 to rotate via the adjusting rod 12.

[0049] Preferably, the two ends of the protrusion 13 are serrated;

[0050] This facilitates better insertion into the inner side of the mating groove 151.

[0051] Preferably, the support block assembly 11 includes a threaded sleeve 111, a support block 112, and a fixing rod 113. The threaded sleeve 111 is fitted onto the threaded cylinder 8 through a threaded portion. The support block 112 is rotatably mounted on the lower end of the threaded sleeve 111, and the other end of the support block 112 is rotatably engaged with the support leg 10. The fixing rod 113 is fixed to the lower end of the inner side of the through groove, and a guide hole that engages with the fixing rod 113 is provided along the long side of the inner side of the support block 112.

[0052] The threaded sleeve 111 is moved by rotating the threaded cylinder 8. The movement of the threaded sleeve 111 drives one end of the support block 112 to move. The moving direction of the support block 112 is guided by the fixing rod 113 so that the support block 112 can tilt better to support the track 1. In addition, a guide rod can also be provided on one side of the threaded sleeve 111 to guide it so that the threaded sleeve 111 can move horizontally better.

[0053] Preferably, the limiting component 7 includes a fixing block 701, a spring 702, a cylinder 703, a toothed block 704, a connecting rod 705, and a limiting roller 706. The fixing block 701 is fixed to one side wall of the track 1. The cylinder 703 is slidably installed on the inner side of the fixing block 701, and the lower end of the cylinder 703 has a spring 702. The upper end of the outer wall of the cylinder 703 is provided with a toothed block 704 that cooperates with the fixing block 701. The connecting rod 705 is fixed on the cylinder 703, and one end of the connecting rod 705 is rotatably provided with a limiting roller 706 that contacts the cable reel 5.

[0054] The limiting roller 706 makes it easy to contact the outer rings at both ends of the cable reel 5, thereby limiting the movement of the cable reel 5 ends. The elastic support of the spring 702 allows for later adjustment of the position of the cylinder 703.

[0055] Preferably, the fixing block 701 has an installation groove on its inner side, and the upper end of the inner side of the installation groove is fixed with a toothed groove 707 that mates with the toothed block 704;

[0056] This facilitates better adjustment of the toothed block 704 and its different toothed grooves 707 to adjust the position of the connecting rod 705 and the limiting roller 706.

[0057] Preferably, multiple toothed blocks 704 are evenly distributed around the circumference of the cylinder 703, which facilitates better rotation and adjustment of the position of the cylinder 703, thereby better adjusting the position of the limiting rollers according to the position of the outer rings at both ends of the cable reel 5.

[0058] Preferably, the inner edge of the through groove is slidably connected with 2, and an adjusting nut 3 for limiting the track 1 is threadedly connected to 2, so as to facilitate the adjustment of the distance between the two tracks 1 according to the axial length of the cable reel 5.

[0059] Preferably, one end of the track 1 is provided with an inclined surface 6 for the cable reel 5 to roll, so that when placed, the cable reel 5 can roll better onto the support roller 4 via the inclined surface 6, so that the cable reel 5 can rotate later for cable feeding.

[0060] The working principle and usage process of this invention are as follows: During the installation and maintenance of overhead lines, the distance between the two tracks 1 is adjusted by loosening the adjusting nut 3 according to the axial length of the cable reel 5, and then the position of the track 1 is locked by tightening the adjusting nut 3. The outer rings at both ends of the cable reel 5 roll onto the track 1 through the inclined surface 6 on one side of the track 1. The outer rings of the cable reel 5 are supported by multiple support rollers 4. The adjusting rod 12 is pushed to slide inside the mounting block 9, so that one end of the protrusion 13 is inserted into the adjusting groove structure inside the threaded cylinder 8. At this time, the adjusting rod 12 is rotated to drive the threaded cylinder 8 to rotate. The threaded cylinder 8 feeds the threaded sleeve 111 through the threaded part. At this time, the fixed rod 113 guides the movement direction of the support block 112, so that the support foot 10 at the lower end of the support block 112 contacts the ground. Similarly, the adjusting rod 12 can be pulled to cooperate with the other threaded cylinder 8 to drive it to rotate, thereby adjusting the other support foot 10, which facilitates the adjustment of the track 1 to be placed horizontally. Furthermore, the support block 112 can support the track 1, so that the track 1 is tilted. Figure 9As shown, the tilt angle is α, which facilitates better pulling of the cable reel 5 to roll and release the cable during cable release. Additionally, the connecting rod 705 can be pressed down to disengage the toothed block 704 at the lower end of the connecting rod 705 from the inside of the toothed groove 707. At this time, the connecting rod 705 can be rotated to make the limiting roller 706 contact the end of the cable reel 5. Releasing the connecting rod 705 allows the toothed block 704 to move upward under the elastic push of the spring 702 to re-engage with the toothed groove 707, thereby locking the position of the connecting rod 705. Furthermore, the limiting roller 706 blocks and restricts the axial movement of the cable reel 5 on the supporting roller 4, ensuring the stability of cable reel 5 during cable release.

[0061] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
