Description

Technical Field

[0001] The invention belongs to the technical field of overhead ground wire installation, in particular to an overhead ground wire riser. Background Art

[0002] Overhead ground wires are devices that protect overhead transmission lines from lightning strikes. In order to improve the safety of line operation, overhead ground wires are generally installed above the protected conductors.

[0003] At present, when installing an overhead ground wire on the top of a certain pole tower, it is usually necessary to use a lifter to lift the ground wire that is hung from the top of the previous pole tower to the ground at the bottom of the pole tower to be installed. However, since the ground wire that is hung from the top of the previous pole tower to the ground at the bottom of the pole tower to be installed is in an inclined state, when the ground wire is lifted to the top of the pole tower to be installed, the ground wire between the two pole towers will be in a bent and drooping state. At this time, it is necessary to manually pull the ground wire to be relatively straight before installation. Therefore, although the existing ground wire lifter can achieve the lifting of the ground wire, the degree of improvement in the overall installation efficiency of the ground wire is relatively limited, and it is urgently needed to be improved. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the embodiments of the present invention is to provide an overhead ground wire riser.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] An overhead ground wire lifter comprises a box body, a winding assembly, a lifting rope, a mounting assembly, a conveying assembly and a fixing assembly.

[0007] The fixing assembly is installed on the side wall of the box body and is used to fix the box body on the top of the tower.

[0008] The winding and unwinding assembly is installed inside the box.

[0009] The mounting assembly is arranged below the box body and is used to mount the ground wire.

[0010] One end of the lifting rope is connected to the winding assembly, and the other end passes around the mounting assembly and is connected to the inner top wall of the box body.

[0011] The conveying assembly is installed on the mounting assembly. When the winding assembly reels one end of the lifting rope and pulls the mounting assembly upward, the conveying assembly is used to convey the ground wire mounted on the mounting assembly, so that the ground wire moves laterally compared to the mounting assembly.

[0012] As a further improvement of the present invention: the conveying assembly includes a reel and a gear,

[0013] The mounting assembly includes two sets of mounting plates and two sets of shaft rods.

[0014] The two groups of mounting plates are relatively distributed, the two groups of shaft rods are arranged between the two groups of mounting plates and are vertically spaced apart, the two ends of the two groups of shaft rods are rotatably connected with the two groups of mounting plates through a group of rotating rods, the four groups of rotating rods respectively penetrate the two groups of mounting plates, and a group of gears are fixedly arranged at one end of the four groups of rotating rods away from the corresponding shaft rods.

[0015] The two groups of gears on the same group of mounting plates are meshed with each other, and a group of reels are fixedly arranged on the outside of the two groups of rotating rods located on the top, respectively.

[0016] The lifting ropes are provided with two groups, one end of the two groups of lifting ropes is connected to the winding assembly, and the other end is respectively passed around the two groups of reels and fixedly connected to the inner top wall of the box body.

[0017] As a further improvement of the present invention: the two groups of rotating rods located above are located above the axes of the two groups of mounting plates.

[0018] As a further improvement of the present invention: square pin holes are provided at one end of the two groups of shaft rods, and square pins matching the two groups of square pin holes are fixedly provided at the ends of the two groups of rotating rods on one group of mounting plates, and a first screw rod is passed through one group of mounting plates, and one end of the first screw rod passes through the other group of mounting plates and is threadedly matched with the mounting plates of the other group.

[0019] As a further improvement of the present invention: the two groups of mounting plates are further connected via a telescopic rod.

[0020] As a further improvement of the present invention: the winding and unwinding assembly includes a winding shaft and a handle.

[0021] The reel is rotatably arranged inside the box, one end of the handle is connected to the reel, and the other end extends to the outside of the box, one end of the two groups of lifting ropes are connected to the reel, and the other end respectively passes around the two groups of reels and is fixedly connected to the inner top wall of the box.

[0022] As a further improvement of the present invention: the fixing assembly includes a fixing clamp, a pressing plate and a second screw rod.

[0023] There are two groups of fixing splints, which are fixedly mounted on the side walls of the box and distributed relatively to each other. One end of the second screw extends between the two groups of fixing splints and is connected to the pressure plate, and the other end passes through one group of fixing splints and is threadedly matched with the fixing splint of the group.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When the ground wire needs to be installed on the top of a certain tower pole, the box body can be fixed to the top of the tower pole by a fixing assembly, and then one end of the lifting rope is unwound by the winding and unwinding assembly, so that the mounting assembly moves downward. When the mounting assembly moves to the ground, the ground wire can be mounted on the mounting assembly, and then the winding and unwinding assembly reels one end of the lifting rope. When one end of the lifting rope is reeled in, the mounting assembly is driven to move upward, thereby pulling the ground wire upward, so that the ground wire moves to the top of the tower pole. While the mounting assembly is pulling the ground wire upward, the ground wire is conveyed by the conveying assembly, so that the ground wire moves laterally compared with the mounting assembly, and the ground wire can be gradually straightened during the lateral movement, thereby preventing the ground wire from sagging when it is lifted to the top of the tower pole, so as to realize convenient installation of the ground wire. Compared with the prior art, while the ground wire is lifted, the ground wire can also be conveyed laterally, so that the ground wire lifted to the top of the tower pole remains in a relatively straightened state, so as to improve the installation efficiency of the ground wire.

DETAILED DESCRIPTION

[0031] The technical solution of the present invention is further described in detail below in conjunction with specific implementation methods.

[0032] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] See also Figure 1 as well as Figure 2 The present embodiment provides an overhead ground wire lifter, comprising a box body 10, a reeling assembly 20, a lifting rope 30, a mounting assembly 40, a conveying assembly 50 and a fixing assembly 60, wherein the fixing assembly 60 is mounted on the side wall of the box body 10 and is used to fix the box body 10 on the top of the pole tower, the reeling assembly 20 is mounted inside the box body 10, the mounting assembly 40 is arranged below the box body 10 and is used to mount the ground wire, one end of the lifting rope 30 is connected to the reeling assembly 20, and the other end bypasses the mounting assembly 40 and is connected to the inner top wall of the box body 10, the conveying assembly 50 is mounted on the mounting assembly 40, when the reeling assembly 20 reels one end of the lifting rope 30 and thereby pulls the mounting assembly 40 upward, the conveying assembly 50 is used to convey the ground wire mounted on the mounting assembly 40, so that the ground wire moves laterally compared to the mounting assembly 40.

[0034] When it is necessary to install the ground wire on the top of a tower pole, the box body 10 can be fixed to the top of the tower pole through the fixing assembly 60, and then one end of the lifting rope 30 is unwound by the winding assembly 20, so that the mounting assembly 40 moves downward. When the mounting assembly 40 moves to the ground, the ground wire can be mounted on the mounting assembly 40, and then the winding assembly 20 reels one end of the lifting rope 30. When one end of the lifting rope 30 is reeled in, the mounting assembly 40 is driven to move upward, and then the ground wire is pulled upward, so that the ground wire is moved to the top of the tower. While the mounting assembly 40 pulls the ground wire upward, the ground wire is conveyed by the conveying assembly 50, so that the ground wire moves horizontally compared to the mounting assembly 40. The ground wire can be gradually straightened during the horizontal movement, thereby preventing the ground wire from sagging when it is lifted to the top of the tower, so as to achieve convenient installation of the ground wire.

[0035] See also Figure 1 , Figure 3 as well as Figure 4In one embodiment, the conveying assembly 50 includes a reel 501 and a gear 502, and the mounting assembly 40 includes two groups of mounting plates 401 and two groups of shafts 402. The two groups of mounting plates 401 are relatively distributed, and the two groups of shafts 402 are arranged between the two groups of mounting plates 401 and are vertically spaced. The two ends of the two groups of shafts 402 are rotatably connected to the two groups of mounting plates 401 through a group of rotating rods 403, and the four groups of rotating rods 403 respectively penetrate the two groups of mounting plates 401. A group of gears 502 are fixedly provided at one end of the rotating rod 403 away from the corresponding shaft rod 402, and the two groups of gears 502 located on the same group of mounting plates 401 are meshed with each other, wherein a group of reels 501 are fixedly provided on the outside of the two groups of rotating rods 403 located above, respectively. Two groups of lifting ropes 30 are provided, one end of the two groups of lifting ropes 30 is connected to the winding and unwinding assembly 20, and the other ends are respectively passed around the two groups of reels 501 and fixedly connected to the inner top wall of the box body 10.

[0036] After the box body 10 is fixed to the top of the tower by the fixing assembly 60, the winding assembly 20 synchronously unwinds one end of the two sets of lifting ropes 30, so that the two sets of mounting plates 401, the two sets of shafts 402, the two sets of reels 501, the four sets of rotating rods 403 and the four sets of gears 502 move downward synchronously. When the mounting plate 401 moves down to the ground, the staff can pass the ground wire through between the two sets of shafts 402 to achieve the mounting of the ground wire. Then the winding assembly 20 reels one end of the two sets of lifting ropes 30. When one end of the two sets of lifting ropes 30 is reeled, the two sets of reels 501 act as movable pulleys to drive the two sets of mounting plates 401 to move upward, and at the same time, the friction of the two sets of lifting ropes 30 on the two sets of reels 501 drives the two sets of The rotating rod 403 rotates compared to the mounting plate 401. When the two sets of rotating rods 403 on the upper side rotate, on the one hand, they drive the upper set of shaft rods 402 to rotate, and on the other hand, they drive the two sets of rotating rods 403 on the lower side to rotate synchronously with the help of the meshing rotation of the gear 502, thereby driving the lower shaft rod 402 to rotate, and the upper shaft rod 402 rotates in opposite directions to the lower shaft rod 402, so that the friction of the two sets of shaft rods 402 on the ground wire when rotating is utilized to transport the ground wire, so that the ground wire moves laterally. In this way, during the process of the ground wire being moved upward, the ground wire also has a lateral movement effect, so that when the ground wire is lifted to the top of the pole tower, the ground wire can be horizontally straightened for convenient and quick installation of the ground wire.

[0037] In one embodiment, the two groups of rotating rods 403 located above are located above the axis of the two groups of mounting plates 401, so that when the two groups of lifting ropes 30 drive the two groups of mounting plates 401 and the ground line to move up, the two groups of mounting plates 401 can remain stable by relying on the gravity of the ground line.

[0038] Since the ground wire has a long portion hanging on the ground during the installation process, it is not easy for the ground wire to pass between the two sets of shaft rods 402 when the mounting assembly 40 is lowered to the ground. Figure 3 as well as Figure 4 In one embodiment, square pin holes 407 are provided at one end of the two groups of shafts 402, and square pins 404 matching the two groups of square pin holes 407 are fixedly provided at the ends of the two groups of rotating rods 403 on one group of mounting plates 401, and a first screw rod 405 is passed through one group of mounting plates 401, and one end of the first screw rod 405 passes through the other group of mounting plates 401 and is threadedly matched with the mounting plates 401 of the group; when the mounting assembly 40 is lowered to the ground, the staff can rotate the first screw rod 405, and the two groups of mounting plates 401 can be moved away from each other through the threaded matching effect of the first screw rod 405 and the other group of mounting plates 401, and the two groups of square pins 404 withdraw from the two groups of square pin holes 407 at one end of the two groups of shafts 402, and a gap (such as a gap through which a ground wire can pass) is formed between the two groups of shafts 402 and one group of mounting plates 401. Figure 4 As shown), at this time, the staff can conveniently move the ground wire from the gap to between the two sets of shafts 402. After the ground wire is moved between the two sets of shafts 402, the staff reversely rotates the first screw 405, thereby making the two sets of mounting plates 401 approach each other. When the two sets of mounting plates 401 approach each other, the two sets of square pins 404 can be reinserted into the two sets of square pin holes 407 at one end of the two sets of shafts 402, thereby confining the ground wire between the two sets of shafts 402.

[0039] See also Figure 3 as well as Figure 4 In one embodiment, the two groups of mounting plates 401 are also connected by a telescopic rod 406. During the rotation of the first screw rod 405, the telescopic movement of the telescopic rod 406 allows the two groups of mounting plates 401 to smoothly move away from and closer to each other.

[0040] See also Figure 1 In one embodiment, the winding and unwinding assembly 20 includes a reel 201 and a handle 202, the reel 201 is rotatably arranged inside the box 10, one end of the handle 202 is connected to the reel 201, and the other end extends to the outside of the box 10, one end of the two groups of lifting ropes 30 is connected to the reel 201, and the other end respectively passes around the two groups of reels 501 and is fixedly connected to the inner top wall of the box 10.

[0041] After the ground wire passes between the two sets of shafts 402, the staff can rotate the handle 202, thereby driving the reel 201 to rotate. When the reel 201 rotates, one end of the two sets of lifting ropes 30 is reeled in. The two sets of lifting ropes 30 use the two sets of reels 501 to pull the two sets of mounting plates 401 and the two sets of shafts 402 upward, thereby driving the ground wire to move up, thereby achieving the lifting of the ground wire.

[0042] In one embodiment, the reel 201 may also be rotated by a motor, which is not limited here.

[0043] See also Figure 2 In one embodiment, the fixing assembly 60 includes a fixing plate 601, a pressure plate 602 and a second screw 603. The fixing plate 601 is provided with two groups, and the two groups of fixing plates 601 are fixedly mounted on the side wall of the box body 10 and are relatively distributed. One end of the second screw 603 extends between the two groups of fixing plates 601 and is connected to the pressure plate 602, and the other end passes through one group of fixing plates 601 and is threadedly matched with the fixing plates 601 of the group.

[0044] By placing two sets of fixing clamps 601 on opposite sides of the pole tower, and then rotating the second screw 603, the second screw 603 cooperates with the thread of the corresponding fixing clamp 601 to drive the pressure plate 602 to move, and the pressure plate 602 presses against the side wall of the pole tower, thereby achieving the fixation of the box body 10 and the winding assembly 20 in the box body 10.

[0045] In the embodiment of the present invention, when it is necessary to install the ground wire on the top of a certain tower pole, the box body 10 can be fixed to the top of the tower pole through the fixing assembly 60, and then the winding assembly 20 is used to unwind one end of the lifting rope 30, so that the mounting assembly 40 moves downward. When the mounting assembly 40 moves to the ground, the ground wire can be mounted on the mounting assembly 40, and then the winding assembly 20 is used to reel in one end of the lifting rope 30. When one end of the lifting rope 30 is reeled in, the mounting assembly 40 is driven to move upward, thereby pulling the ground wire upward, so that the ground wire moves upward. The ground wire is moved to the top of the pole tower. While the mounting assembly 40 pulls the ground wire upward, the ground wire is transported by the transport assembly 50, so that the ground wire moves laterally compared to the mounting assembly 40. The ground wire can be gradually straightened during the lateral movement, thereby preventing the ground wire from sagging when it is lifted to the top of the pole tower, so as to achieve convenient installation of the ground wire. Compared with the prior art, while the ground wire is lifted, the ground wire can also be transported laterally, so that the ground wire lifted to the top of the pole tower remains in a relatively straightened state, so as to improve the installation efficiency of the ground wire.

[0046] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
