Description

Technical Field

[0001] The invention relates to the technical field of circuit detection, and in particular to a wiring pulley for a live working elevator. Background Art

[0002] The main function of the live working self-propelled pulley is to serve as a tool for moving and fixing the working point when performing live working on the conductor. It is usually used in conjunction with an operating rod with a hook. The power worker first hangs the pulley on the hook of the operating rod, and then hangs the pulley on the conductor through the operating rod. The design of the pulley allows the pulley to move freely on the conductor, making it convenient for the workers to perform maintenance work at different locations and improving work efficiency.

[0003] In order to facilitate the workers to hang it on the wire, the existing live working self-propelled pulleys often use a single pulley to connect with the wire for use. At the same time, in order to ensure the stability of the connection, a frame with a notch is provided on the outside of the pulley. Furthermore, some pulleys are provided with a self-locking structure at the notch to further improve the connection stability between the pulley and the wire. However, when a single pulley is used, there is a possibility that the wire will deviate and get stuck between the pulley and the frame due to environmental factors. In addition, when a single pulley is used, there are too few contact points with the wire, which may cause the pulley to deviate, causing its frame to contact with the wire and damage the wire. It will also have a safety impact on the personnel or equipment connected to the pulley. Summary of the invention

[0004] The purpose of the present invention is to provide a routing pulley for live working hoist to solve the problem that the self-propelled pulley in the prior art uses a single pulley to connect with the conductor, which easily causes the pulley frame to deviate and move by friction on the conductor and the pulley to detach from the conductor and cause locking.

[0005] The present invention solves the shortcomings of the above technical problems and adopts the following technical solutions: a wiring pulley for a live working lift, comprising an inverted U-shaped support frame with a lifting ring on the top and two rolling wheels arranged in the support frame, guide feet are arranged at the four corners of the support frame, two rotating columns perpendicular to the side wall are arranged below the support frame, the opposite ends of the two rotating columns are rotatably connected to the linkage columns perpendicular to the two rotating columns, the two ends of the linkage columns are slidably connected to the oblique grooves opened on the two guide feet on the same side, and the oblique grooves are obliquely arranged to be inclined to the inside of the upper side of the support frame;

[0006] Two sliding grooves are provided on both side walls of the support frame, and sliding blocks slide in the sliding grooves. The sliding blocks are rotatably connected to the ends of the rotating shafts of the rolling wheels, and the rotating columns are rotatably connected to the rotating shafts on the same sides of the two rolling wheels through two connecting rods.

[0008] As a further optimization of the wiring pulley for live working elevator of the present invention: the sliding groove is arranged in an inclined shape toward the center of the support frame.

[0009] As a further optimization of the wiring pulley for live working elevator of the present invention: the length of the sliding groove is greater than the distance between the rotating column and the opposite surfaces of the two rolling wheels.

[0010] As a further optimization of the wiring pulley for live working elevator of the present invention: conical cylinders are fixedly provided on the outer circumferential surfaces of the opposite sides of the two rotating columns, a clamping ring is provided on the end face of any conical cylinder, and a clamping groove cooperating with the clamping ring is provided on the other conical cylinder.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention provides two rotating columns with a certain interval to allow the wire to pass between the two rotating columns, and the two rolling wheels are connected to the top of the wire and move away from each other under the drive of the wiring pulley's own weight, and the corresponding four connecting rods will drive the two rotating columns to move up synchronously. While the two rotating columns move up synchronously, they will also be driven by the oblique groove and the linkage column to approach each other to achieve docking, so that the two rotating columns are combined together, and then the two rotating columns and the two rolling wheels will be stably connected to the wire in an inverted T shape, that is, the contact point between the support frame and the wire is increased, thereby reducing the possibility of the support frame derailing from the wire, or the wire sliding between the rolling wheel and the support frame, causing the support frame to be stuck on the wire.

DETAILED DESCRIPTION

[0024] In order to better understand the present invention, the content of the present invention is further explained below in conjunction with embodiments, but the content of the present invention is not limited to the following embodiments.

[0025] like Figure 1-4As shown, a routing pulley for a live working elevator is similar to the prior art in that it has a support frame 102 with a lifting ring 101 on the top. Preferably, reinforcing ribs are provided between the lifting ring 101 and the support frame 102 to improve the stability of the connection between the two. The provision of the lifting ring 101 can facilitate the staff to move the support frame 102 to a position corresponding to the conductor 6 through a drone or an operating lever. A rolling wheel 2 is provided in the support frame 102, and the rolling wheel 2 can be connected to the transmission line to realize the movement of the support frame 102 on the conductor 6.

[0026] Different from the prior art, Figure 1 and Figure 2 As shown, the support frame 102 is set in a U-shaped guide, and two rotating columns 503 are arranged at the bottom of the center of the support frame 102. The two rotating columns 503 are arranged horizontally and perpendicular to the side walls of the support frame 102. The opposite ends of the two rotating columns 503 are rotatably connected to the connecting columns 502 perpendicular to them. The two ends of the two connecting columns 502 are respectively slidably connected to the oblique grooves 501 provided on the four guide feet 106. When the two rotating columns 503 move upward, as shown in FIG. Figure 3 and Figure 4 As shown, the setting of the oblique groove 501 will cooperate with the linkage column 502 to push the two rotating columns 503 closer to each other, so that the two rotating columns 503 are combined. Preferably, a conical cylinder 504 is fixedly connected to the two rotating columns 503. The combination of the two conical cylinders 504 can improve the stability of the connection between the wire 6 and the rotating column 503. The opposite ends of the two rotating columns 503 are rotatably connected to the rotating shaft of the rolling wheel 2 through the connecting rod 3. Preferably, the two rolling wheels 2 are V wheels to improve the stability of the connection between the wire 6 and the rolling wheel 2.

[0027] like Figure 1-4 As shown, the two rolling wheels 2 are both arranged in the support frame 102, and the ends of the rotating shafts of the two rolling wheels 2 pass through the sliding block 103 and are arranged outside the support frame 102. Two sliding grooves 105 are provided on the two side walls of the support frame 102. The four sliding grooves 105 are respectively slidably matched with the four sliding blocks 103. The four sliding grooves 105 are all obliquely arranged at the lower part of the center of the support frame 102 and away from the higher part of the center of the support frame 102. The arrangement of the sliding grooves 105 and the sliding block 103 can enable the two rolling wheels 2 to be supported by the wire 6. Under the pressure of the support frame 102 and the equipment connected to the support frame 102, the wires 6 can be stably moved away from each other, and then the wires 6 can be clamped between the two rolling wheels 2 and the two combined rotating columns 503. Next, the support frame 102 can be stably moved on the wires 6, or positioned at the corresponding position of the wires 6. Reinforcement columns 104 are provided in the four sliding grooves 105. The four groups of reinforcement columns 104 are respectively slidably matched with the four sliding blocks 103, thereby ensuring the stability of the structure and the stability of the sliding of the sliding blocks 103.

[0028] The guide feet 106 on both sides are provided with locking ropes 401, and both ends of the locking ropes 401 pass through the support frame 102 and are fixedly connected to the sliding block 103. The locking rope 401 is located between the two guide feet 106 on one side and is fixedly provided with a padlock ring 402. Specifically, the padlock ring 402 is a hinge lock setting, which is convenient for the staff to connect the heavy object or rope to the padlock ring 402 stably and safely, and then the two sliding blocks 103 are pulled away from each other by the locking rope 401. The upper part of the oblique groove 501 is connected to the auxiliary groove 403 opened on the guide foot 106. When the blocks 103 move away from each other and the connecting rod 3 drives the two rotating columns 503 to continue to move upward, the linkage column 502 can slide in the auxiliary groove 403 to ensure the stability of the upward movement of the rotating column 503, and then the combined rotating column 503 can be made to cooperate with the two rolling wheels 2 to squeeze the wire 6, and then the stability of the support frame 102 being positioned at the corresponding position on the wire 6 can be strengthened, and the length of the sliding groove 105 is greater than the distance between the opposite surfaces of the rotating column 503 and the two rolling wheels 2, so that it is convenient for the staff to increase the stability of the support frame 102 positioned at the corresponding position of the wire 6 as needed.

[0029] A clamping ring 505 is fixedly provided on the end surface of the rotating column 503 and the corresponding conical cylinder 504 on one side, and a clamping groove 506 is provided on the end surface of the other rotating column 503 and the corresponding conical cylinder 504. The clamping groove 506 and the clamping ring 505 are clearance-matched. When the two rotating columns 503 are close to each other and combined together, the clamping ring 505 will be inserted into the clamping groove 506, thereby maintaining the stability of the connection between the two conical cylinders 504 and the two rotating columns 503. Figure 3 and Figure 4 As shown, the two rolling wheels 2 can also be stably mounted on the wire 6 in an inverted T shape.

[0030] During specific use, first connect the drone or operating rod to the hanging ring 101, then the support frame 102 can be moved above the wire 6, and then the four guide feet 106 will cooperate with the two binding columns 107 to guide the wire 6 to enter between the two rotating columns 503, and then the wire 6 will pass through the two rotating columns 503 and connect with the two rolling wheels 2, and then the connection between the drone or operating rod and the hanging ring 101 can be cancelled, and then the weight of the support frame 102 and the structure connected to the support frame 102 will be applied to the wire 6 through the two rolling wheels 2, and then the two rolling wheels 2 will move away from each other under the guidance of the sliding block 103 and the sliding groove 105. The two rolling wheels 2 move away from each other and the corresponding connecting rod 3 will be used to move the two rotating columns 503 upward, and the two rotating columns During the upward displacement of 503, the oblique groove 501 will be used to guide the two rotating columns 503 to approach each other and dock with each other while displacing upward. At the same time, the two conical cylinders 504 will be brought close to each other to form a V-shaped wheel at the lower end. While docking, the clamping ring 505 and the clamping groove 506 will be used to make the connection more stable. Next, the two rolling wheels 2 will cooperate with the two conical cylinders 504 and the rotating column 503 combined on the lower side to squeeze the wire 6, thereby achieving a certain degree of self-locking and movement of the support frame 102 on the wire 6, and can reduce the probability of the support frame 102 derailing from the wire 6 through the larger contact position of the three points, and at the same time, it also reduces the probability of the two guide wheels and the combined two conical cylinders 504 and the edge of the rotating column 503 cooperating with the support frame 102 to jam the wire 6.

[0031] After the support frame 102 is erected on the conductor 6, if it is necessary to further lock the support frame 102 to a suitable position on the conductor 6, the corresponding counterweight block or a rope that can continuously apply weight can be hung on the padlock ring 402, and then the degree to which the four sliding blocks 103 are separated from each other can be further increased, thereby increasing the force of the combined two conical cylinders 504 and the two rotating columns 503 in conjunction with the two rolling wheels 2 to press the conductor 6, thereby stably positioning the support frame 102 to a suitable position on the conductor 6.

[0032] During use, the corresponding equipment or the staff themselves can be connected through the binding column 107, and can also be connected through the hook 108 set on the binding column.

[0033] The above describes the specific embodiments of the present invention. It should be understood that the present invention is not limited to the above specific embodiments, and those skilled in the art may make various modifications or variations within the scope of the claims, which do not affect the essence of the present invention.
