Description

Technical Field

[0001] The present invention belongs to the technical field of transmission line maintenance equipment, and particularly relates to an anti-slip device for climbing transmission lines. Background Art

[0002] In current overhead line maintenance operations, construction workers need to walk directly on the surface of the conductor. Due to the large inclination angle of the drainage line, the friction coefficient between the conventional work shoes and the conductor is insufficient (about 0.3 - 0.5), so it is easy to slip during climbing, and the operation efficiency is low. At the same time, there is a safety hazard of falling from a height during the slipping process (statistics show that such accidents account for 23% of the power high-altitude operation accidents). Existing solutions mostly improve the sole pattern or increase the anti-slip coating, but the increase in the friction coefficient is limited (up to about 0.6), which cannot meet the anti-slip requirements of large-angle conductors; existing solutions also add 3mm deep corrugated grooves to the sole, which can increase the friction coefficient to 0.45 - 0.55, but the grooves are easily stuck by the stranding gaps of the conductor; some existing solutions use neodymium iron boron magnets to generate adsorption force, but it is only applicable to steel core aluminum stranded conductors (magnetic flux ≥ 0.8T) and cannot be used for non-magnetic composite conductors; some existing solutions clamp on the conductor through mechanical fixtures, but due to the excessive self-weight of the mechanical fixtures (≥ 4.5 kg / each), the operation flexibility of construction workers is affected. Summary of the Invention

[0003] In order to solve the problem that construction workers are prone to slip when walking on the surface of the conductor in the prior art. The present invention provides an anti-slip device for climbing transmission lines, which can prevent construction workers from slipping when walking on the surface of the conductor.

[0004] The technical solution adopted by the anti-slip device for climbing transmission lines of the present invention is as follows:

[0005] An anti-slip device for climbing transmission lines includes a boot body for contacting and fixing with shoes. A main frame that is sleeved on the conductor and can be opened and closed is arranged at the bottom of the boot body. A roller that can move along the length direction of the main frame and contacts the conductor is arranged in the main frame and is provided with a rack constraint. At the same time, an elastic reset mechanism for resetting the roller is arranged on the main frame. A fixing strip that cooperates with the conductor is arranged at the bottom inside the main frame, and an auxiliary support block that cooperates with the fixing strip is arranged at the end of the main frame.

[0006] The further improvement of the technical solution of the present invention lies in that: the boot body includes a boot sole fixedly connected to the main frame. One end of the top of the boot sole is provided with a boot heel, and a buckle is also arranged at the top of the boot sole.

[0007] A further improvement of the technical solution of the present invention lies in that: the main frame includes two side plates vertically fixed at the bottom of the boot body and parallel to each other. Each side plate is arranged in a right trapezoid shape, and a bottom plate is provided at the bottom of the two side plates. Among them, the bottom plate is hinged to one of the side plates, and a locking mechanism is provided between the other side plate and the bottom plate.

[0008] A further improvement of the above technical solution of the present invention lies in that: the locking mechanism includes a locking pin horizontally arranged on the side plate, and a locking block cooperating with the locking pin is provided on the bottom plate.

[0009] A further improvement of the technical solution of the present invention lies in that: racks are arranged on both inner walls of the main frame along its length direction. The roller is located below the rack, and gears meshing with the rack are coaxially arranged at both ends of the roller.

[0010] A further improvement of the above technical solution of the present invention lies in that: a connecting rod penetrating through the gear is fixedly connected to the end of the roller, and the gear is in interference fit with the connecting rod. Among them, a strip-shaped hole parallel to the rack is opened below the rack on each side plate, and the end of the connecting rod penetrates through the strip-shaped hole and extends to the outside of the main frame.

[0011] A further improvement of the above technical solution of the present invention lies in that: the elastic reset mechanism includes a spring located outside the main frame and connected to the connecting rod.

[0012] A further improvement of the technical solution of the present invention lies in that: the auxiliary support block is installed at the short end of the main frame.

[0013] A further improvement of the technical solution of the present invention lies in that: a first groove cooperating with the wire is axially opened on the surface of the roller, and second grooves cooperating with the wire are opened at the top of the fixing strip and the bottom of the auxiliary support block.

[0014] A further improvement of the above technical solution of the present invention lies in that: wear-resistant layers are provided on the surfaces of the first groove and the second groove.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by the present invention includes:

[0016] In the present invention, the provided boot body can connect the present invention to the shoes worn by construction workers, thus facilitating the construction workers to climb on the wire through the present invention; in the present invention, the provided main body frame facilitates the installation of the present invention on the wire; in the present invention, through the mutual cooperation of the provided rollers and fixing strips, the wire can be firmly clamped after the construction workers and the present invention slide down a short distance along the wire, thereby preventing the construction workers and the present invention from continuing to slide down and facilitating the continuous climbing of the construction workers; at the same time, through the mutual cooperation of the auxiliary support blocks and the fixing strips, an auxiliary support function can be achieved; the provided elastic reset mechanism in the present invention can make the rollers return to their original positions when the construction workers take a step, release the wire, and facilitate taking a step.

[0017] In the present invention, since the side plate of the main body frame is a right trapezoid, when the roller is located at the longer end of the main body frame, the distance between the roller and the fixing strip is larger, thereby releasing the wire to facilitate the construction workers to take a step; when the roller is located at the shorter end of the main body frame, the distance between the roller and the fixing strip is smaller, thereby firmly clamping the wire to prevent the construction workers from sliding down.

[0018] In the present invention, through the provided first groove and second groove, the contact area between the roller, the fixing strip and the auxiliary support block and the wire can be increased, thereby increasing the friction force when using the present invention and facilitating the use of the present invention.

[0031] To make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in combination with the specific implementation mode and with reference to the attached drawings. In the following description, the description of well-known structures and technologies is omitted to avoid unnecessarily confusing the concept of the present invention.

[0032] Embodiment 1

[0033] Refer to Figures 1 - 5 It can be seen that this embodiment includes a boot body 1. The bottom of the boot body 1 is fixedly connected with a main frame 2. Two openings of different sizes are respectively opened at both ends of the main frame 2. A roller 3 that can move back and forth along the length direction of the main frame 2 is arranged inside the main frame 2. At the same time, a fixed bar 5 is arranged along the length direction at the bottom inside the main frame 2, and an auxiliary support block 6 that cooperates with the fixed bar 5 is fixedly connected to the top of the end of the main frame 2 with a smaller opening. At the same time, an elastic reset mechanism connected to the roller 3 is also arranged outside the main frame 2 in this embodiment. When this embodiment is specifically used, first, this embodiment is installed on the conducting wire 8 through the main frame 2, and then the shoes of the construction worker are stepped on the boot body 1 and the shoes and the boot body 1 are fixedly connected together. When the construction worker climbs on the conducting wire 8, the main frame 2 slides down a short distance along the inclined conducting wire 8. During the sliding process of the main frame 2, the roller 3 moves towards the end of the main frame 2 with a smaller opening until the roller 3 and the fixed bar 5 cooperate with each other to firmly clamp the conducting wire 8, thereby preventing the main frame 2 from continuing to slide down. When the construction worker takes a step, the construction worker drives the main frame 2 to move upward along the conducting wire 8. At this time, the roller 3 moves towards the end of the main frame 2 with a larger opening under the action of the elastic reset mechanism, loosening the conducting wire 8, so as to facilitate the construction worker to take a step. Repeat the above two steps in sequence to complete the climbing of the construction worker.

[0034] In this embodiment, the boot body 1 includes a sole 11 fixed on the top of the main frame 2. A heel 12 is fixedly connected to the sole 11 at the end of the main frame 2 with a larger opening. At the same time, a buckle 13 is also fixedly connected to the sole 11. The buckle 13 can be a commonly used magic tape or elastic tape in the prior art, etc.

[0035] In this embodiment, the main frame 2 includes two side plates 21 vertically fixed to the bottom of the boot sole 11. Each side plate 21 is in the shape of a right trapezoid, so that the openings at both ends of the main frame 2 are large at one end and small at the other end. At the same time, the two side plates 21 are parallel to each other. A bottom plate 22 is arranged on the right-angle side of the two side plates 21. Specifically, the bottom plate 22 is hinged to one of the side plates 21 through a hinge. A locking pin 23 is also fixedly connected to the two side plates 21. At the same time, a locking block 24 matched with the locking pin 23 is fixedly connected to the bottom plate 22. The locking block 24 is provided with a jack 241 for the convenient insertion of the locking pin 23.

[0036] In the specific setting of the roller 3 in this embodiment, a rack 25 is fixedly connected to the opposite side of the two side plates 21, and each rack 25 is parallel to the inclined side of the side plate 21. At the same time, gears 31 meshing with the racks 25 are coaxially fixedly connected to both ends of the roller 3. When the gears 31 are specifically installed, a connecting rod 32 passing through the gears 31 can be fixedly connected to the central positions at both ends of the roller 3, and the gears 31 are in interference fit with the connecting rod 32.

[0037] At the same time, a strip-shaped hole 26 is opened at the position corresponding to the connecting rod 32 below the rack 25 on the side plate 21. The strip-shaped hole 26 is parallel to the rack 25, and the connecting rod 32 passes through the corresponding strip-shaped hole 26 and extends to the outside of the main frame 2.

[0038] In this embodiment, the elastic reset mechanism includes springs 4 located outside the two side plates 21, and each spring 4 is arranged along the length direction of the strip-shaped hole 26. One end of the spring 4 is fixedly connected to one end of the short side of the corresponding side plate 21 through a first ear seat 41, and the other end of the spring 4 is connected to the end of the connecting rod 32 exposed outside the main frame 2 through a second ear seat 42. The second ear seat 42 is rotatably connected to the end of the connecting rod 32. Specifically, the second ear seat 42 is connected to the end of the connecting rod 32 through a rotating shaft.

[0039] In this embodiment, the fixing strip 5 is fixedly installed on the bottom plate 22 along the length direction of the bottom plate 22. At the same time, a first groove 33 matched with the wire 8 is axially opened on the surface of the roller 3 in this embodiment, and second grooves 7 matched with the guide are opened at the top of the fixing strip 5 along its own length direction and at the bottom of the auxiliary support block 6. The cross sections of the first groove 33 and the second groove 7 can be in the shapes of an arc or a V shape, etc., to increase the contact area between the roller 3, the fixing strip 5, the auxiliary support block 6 and the wire 8. At the same time, wear-resistant layers are laid on the surfaces of the first groove 33 and the second groove 7. The wear-resistant layer can be made of materials such as rubber. On the one hand, it can increase the friction between the roller 3, the fixing strip 5, the auxiliary support block 6 and the wire 8. On the other hand, it can protect the roller 3, the fixing strip 5 and the auxiliary support block 6 to prevent the friction loss from being too fast. At the same time, the wear-resistant layer can also prevent the roller 3, the fixing strip 5 and the auxiliary support block 6 from damaging the wire 8.

[0040] The working principle of the anti-slip device for climbing transmission lines in this embodiment is as follows:

[0041] As Figures 6 - 8 shown, first, pull out the pin in the fixing pin, then rotate the bottom plate 22 to open the main frame 2, place this embodiment on the wire 8, then rotate the bottom plate 22 in the reverse direction to its original position, and insert the pin into the jack 241 of the locking block 24, thereby installing this embodiment on the wire 8.

[0042] Then step the shoes of the construction worker on the boot body 1, and fix the shoes and the boot body 1 together through the buckle 13. As Figure 9 shown, when the construction worker steps into this embodiment, the main frame 2 will slide downward a short distance along the wire 8 under the force of the construction worker stepping downward and its own gravity. During the downward sliding process of the main frame 2, the wire 8 moves leftward relative to this embodiment, so that the roller 3 rotates clockwise. When the roller 3 rotates, it is restricted by the rack 25 and the strip hole 26, so that the roller 3 moves leftward while rotating. At this time, the roller 3 moves towards the end with a smaller opening of the main frame 2, and the spring 4 is compressed until the roller 3 and the fixed strip 5 cooperate with each other to firmly clamp the wire 8, realizing the locking and clamping of the wire 8. The auxiliary support block 6 serves as an auxiliary second support point to further provide support for the wire 8, thereby preventing the main frame 2 from continuing to slide downward significantly along the wire 8. At this time, the construction worker can step on this embodiment stably and climb upward.

[0043] As Figure 10 shown, when the construction worker takes a step, the construction worker gently lifts this embodiment and moves forward (to the left as shown in the figure), driving the main frame 2 to move upward along the wire 8. At this time, the roller 3 rotates counterclockwise under the elastic action of the compressed spring 4 and the frictional force of the wire 8, and moves towards the end with a larger opening of the main frame 2, loosening the wire 8, so as to facilitate the construction worker to take a step. Repeat the above two steps in sequence to complete the climbing of the construction worker.

[0044] Embodiment Two

[0045] Compared with Embodiment One, in this embodiment, the first ear seat 41 of the spring 4 is installed at one end of the long side of the corresponding side plate 21.

[0046] When construction workers step into this embodiment, the main frame 2 will slide downward along the wire 8 for a short distance under the force of the construction workers stepping downward and its own gravity. During the downward sliding process of the main frame 2, the wire 8 moves leftward relative to this embodiment, causing the roller 3 to rotate clockwise. When the roller 3 rotates, it is restricted by the rack 25 and the strip-shaped hole 26, so that the roller 3 moves leftward while rotating. At this time, the roller 3 moves towards the end of the main frame 2 with a smaller opening, and the spring 4 is stretched until the roller 3 and the fixed strip 5 cooperate with each other to firmly clamp the wire 8, realizing the locking and clamping of the wire 8. The auxiliary support block 6 serves as an auxiliary second support point to further provide support for the wire 8, thereby preventing the main frame 2 from sliding further. At this time, the construction workers can step on this embodiment stably and climb upward.

[0047] When the construction workers take a step, they gently lift this embodiment and move forward, driving the main frame 2 to move upward along the wire 8. At this time, the roller 3 rotates counterclockwise under the elastic action of the stretched spring 4 and the frictional force of the wire 8, and moves towards the end of the main frame 2 with a larger opening, loosening the wire 8, thus facilitating the construction workers to take a step. Repeat the above two steps in sequence to complete the climbing of the construction workers.

[0048] In the above embodiment, the present invention provides an anti-slip device for climbing a transmission line. In the present invention, through the set boot body, the present invention can be connected to the shoes worn by construction workers, thus facilitating the construction workers to climb on the wire through the present invention; in the present invention, through the set main frame, it is convenient to install the present invention on the wire; in the present invention, through the mutual cooperation of the set roller and the fixed strip, the wire can be firmly clamped after the construction workers and the present invention slide downward along the wire for a short distance, thereby preventing the construction workers and the present invention from sliding further and facilitating the continuous climbing of the construction workers; at the same time, through the mutual cooperation of the auxiliary support block and the fixed strip, an auxiliary support effect can be achieved; the elastic reset mechanism set in the present invention can make the roller return to its original position when the construction workers take a step, loosen the wire, and facilitate taking a step.

[0049] The above-described embodiments are only used to describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by those of ordinary skill in the art to the technical solution of the present invention should fall within the protection scope of the present invention.
