Description

Technical Field

[0001] The utility model relates to the technical field of electric power construction, in particular to a wire tightener for electric power construction. Background Technique

[0002] With the rapid development of society, the application of electric power equipment is becoming more and more extensive, the demand for electric power is increasing, and the role of the wire tightener in tightening the conductor during the construction of overhead lines is becoming more and more important. During the process of electric power construction for wire maintenance and installation, personnel will use an insulating wire tightener for electric power construction to clamp and fix the wire to prevent the wire from moving up and down during electric power construction, and then use the insulating wire tightener for electric power construction to assist personnel in carrying out electric power construction operations.

[0003] For example, the patent document with the publication number of CN219801687U discloses an insulating wire tightener for electric power construction. The wire is placed on the support plate, and then the pressing plate is moved downward to press the wire, and the wire is tightly pressed. Then, the pressing plate is fixed on the support plate by using a threaded rod. After that, the auxiliary disc is rotated to drive the limiting rod and the lifting plate to rotate, so that the wire rotates, thereby adjusting the angle of the wire. After adjusting the angle of the wire, the limiting rod needs to be inserted into the limiting hole. Then, a force needs to be applied to the adjusting plate to move it up and down. When the adjusting plate moves up and down, it will cause the support plate to move up and down together, so that the wire moves up and down, thereby adjusting the height of the wire to keep a safe distance from the construction personnel.

[0004] However, in the above patent during use, when using the pressing plate to tightly press the cable, it is not easy to master the pressing force of the pressing plate on the cable. If the pressing force is too large, the cable will be deformed, affecting the subsequent use of the cable. If the pressing force is too small, the cable will be loose, affecting the work. Content of the Utility Model

[0005] The purpose of the utility model is to provide a wire tightener for electric power construction to solve the above problems.

[0006] The utility model realizes the above purpose through the following technical solutions:

[0007] A wire tightener for electric power construction includes a base. An adjustment mechanism is installed on the top of the base. A placement mechanism is arranged on the top of the adjustment mechanism. An installation mechanism is installed on the top of the placement mechanism. The installation mechanism includes a movable frame. A locking mechanism is arranged in the movable frame. The locking mechanism includes a mounting plate. The mounting plate is slidably connected to the inner walls on both sides of the movable frame. Two fixing columns are fixedly connected to the bottom of the mounting plate. Springs are arranged on the fixing columns. A sliding plate is arranged at the bottom of the spring. The sliding plate is slidably connected to the fixing columns. The two sides of the sliding plate are slidably connected to the inner wall of the movable frame. A pressing plate is fixedly connected to the bottom of the sliding plate.

[0008] Preferably, the adjusting mechanism includes a worm, which is installed on the top of the base through a bearing seat. A telescopic column is rotatably connected in the base, and a worm gear is fixedly connected to the telescopic column. The worm gear meshes with the worm.

[0009] Preferably, the placing mechanism includes a fixing frame, which is fixedly connected to the top of the telescopic column. First connecting plates are fixedly connected to the outer walls on both sides of the fixing frame, and a fixing plate is fixedly connected to the inner wall at the bottom of the fixing frame.

[0010] Preferably, both the fixing frame and the movable frame are U-shaped frames.

[0011] Preferably, both the fixing plate and the pressing plate are arc-shaped plates, and a plurality of anti-slip pads are fixedly connected to both the fixing plate and the pressing plate.

[0012] Preferably, the movable frame is placed on the top of the fixing frame. Second connecting plates are fixedly connected to both sides of the movable frame.

A threaded tube is fixedly connected to the top plate of the movable frame, and a threaded rod is threadedly connected in the threaded tube. The bottom of the threaded rod is rotatably connected to the mounting plate.

[0013] The beneficial effects are as follows: The installation mechanism can drive the locking mechanism to move downward until the pressing plate is closely attached to the surface of the wire. Then, continue to drive the locking mechanism to move downward. At this time, the pressing plate will not continue to move downward due to the obstruction of the wire. Therefore, the mounting plate will move downward and compress the spring, and at the same time, the spring will have a rebounding force, thereby using the pressing plate to lock the wire. By adjusting the compression amount of the spring, the rebounding force of the spring can be controlled, and further, the squeezing force of the pressing plate on the wire can be controlled, avoiding wire deformation and affecting subsequent use.

[0023] The present utility model will be further described below in conjunction with the drawings:

[0024] As Figures 1 - 4 shown, a wire tightener for electric power construction includes a base 1. A top of the base 1 is provided with an adjustment mechanism for adjusting the position of an electric wire. A top of the adjustment mechanism is provided with a storage mechanism for placing the electric wire. A top of the storage mechanism is installed with a mounting mechanism. The mounting mechanism includes a movable frame 401. A locking mechanism for fixing the electric wire is arranged in the movable frame 401.

[0025] The storage mechanism includes a fixed frame 301, which is connected to the top of the telescopic column 202 by bolts. Both the fixed frame 301 and the movable frame 401 are U-shaped frames. First connecting plates 303 are welded to the outer walls on both sides of the fixed frame 301, and a fixed plate 302 is welded to the inner wall at the bottom of the fixed frame 301. Both the fixed plate 302 and the pressing plate 505 are arc-shaped plates, and a plurality of anti-slip pads 506 are connected by screws in both the fixed plate 302 and the pressing plate 505. When in use, place the wire on the fixed plate 302, then place the movable frame 401 on the top of the fixed frame 301, align the second connecting plate 402 with the first connecting plate 303, and then lock the second connecting plate 402 and the first connecting plate 303 with the locking bolts 403, thereby locking the movable frame 401 and the fixed frame 301. The movable frame 401 is placed on the top of the fixed frame 301. Second connecting plates 402 are welded to both sides of the movable frame 401. A plurality of locking bolts 403 are arranged between the first connecting plate 303 and the second connecting plate 402. A threaded pipe 404 is welded to the top plate of the movable frame 401, and a threaded rod 405 is threadedly connected in the threaded pipe 404. The bottom of the threaded rod 405 is rotatably connected to the mounting plate 501 through a bearing. Rotate the threaded rod 405 through the turntable, so that the threaded rod 405 rotates and moves downward in the threaded pipe 404, and then drives the locking mechanism to move downward.

[0026] The locking mechanism includes a mounting plate 501, which is slidably connected to the inner walls on both sides of the movable frame 401. Two fixed columns 502 are connected to the bottom of the mounting plate 501 by screws. A spring 503 is arranged on the fixed column 502. A sliding plate 504 is arranged at the bottom of the spring 503. The sliding plate 504 is slidably connected to the fixed column 502. The two sides of the sliding plate 504 are slidably connected to the inner wall of the movable frame 401. A pressing plate 505 is welded to the bottom of the sliding plate 504. Drive the locking mechanism to move downward through the mounting mechanism until the pressing plate 505 is closely attached to the surface of the wire. Then continue to rotate the threaded rod 405 through the turntable to drive the mounting plate 501 to continue to move downward. Since the pressing plate 505 will not continue to move downward under the obstruction of the wire at this time, the spring 503 can be compressed by moving the mounting plate 501 downward. At the same time, the spring 503 will generate a certain rebound force, which is then transmitted to the pressing plate 505 through the sliding plate 504, and then the wire is locked by the pressing plate 505. By adjusting the compression amount of the spring 503, the rebound force of the spring 503 can be controlled, and then the pressing force of the pressing plate 505 on the wire can be controlled to avoid deforming the wire and affecting subsequent use.

[0027] The adjustment mechanism includes a worm 201. The worm 201 is installed on the top of the base 1 through a bearing seat. A telescopic column 202 is rotatably connected in the base 1 through a bearing. A worm gear 203 is key-connected to the telescopic column 202. The worm gear 203 meshes with the worm 201. By rotating the worm 201 through a turntable, the worm gear 203 is driven to rotate, thereby driving the telescopic column 202 to rotate, and further driving the object placing mechanism and the installation mechanism to rotate, so as to adjust the angle of the clamped wire. Then, by adjusting the telescopic column 202, the height of the wire is adjusted, which is convenient for the maintenance personnel to work.

[0028] Working principle: When in use, first place the wire on the fixed plate 302, then place the movable frame 401 on the top of the fixed frame 301 and align the second connecting plate 402 with the first connecting plate 303. Then lock the second connecting plate 402 and the first connecting plate 303 with a locking bolt 403, so as to lock the movable frame 401 and the fixed frame 301. Then rotate the threaded rod 405 through the turntable, so that the threaded rod 405 rotates and moves downward in the threaded tube 404, and further drives the locking mechanism to move downward until the pressing plate 505 is closely attached to the surface of the wire. Then continue to rotate the threaded rod 405 through the turntable to drive the mounting plate 501 to continue to move downward. Since the pressing plate 505 will not continue to move downward under the obstruction of the wire at this time, the mounting plate 501 can squeeze the spring 503 when moving downward. At the same time, the spring 503 will generate a certain rebound force, which is transmitted to the pressing plate 505 through the sliding plate 504, and then the wire is locked by the pressing plate 505. By adjusting the compression amount of the spring 503, the rebound force of the spring 503 can be controlled, and then the extrusion force of the pressing plate 505 on the wire can be controlled to avoid deforming the wire and affecting subsequent use. Then rotate the worm 201 through the turntable to drive the worm gear 203 to rotate, thereby driving the telescopic column 202 to rotate, and further driving the object placing mechanism and the installation mechanism to rotate, so as to adjust the angle of the clamped wire. Then, by adjusting the telescopic column 202, the height of the wire is adjusted, which is convenient for the maintenance personnel to work.
