Description

Technical Field

[0001] This utility model patent relates to the field of power transmission line construction, specifically a climbing device for power transmission line construction. Background Technology

[0002] As a crucial piece of wiring equipment in power transmission line construction, utility poles not only allow for the safe installation of overhead power lines at high elevations, but also serve as installation points for various electrical equipment during construction. Climbing devices are essential for ascending these poles, with foot straps being the primary type. These are curved iron tools worn over shoes for climbing poles. They are typically made of high-strength seamless tubing, heat-treated, and offer advantages such as light weight, high strength, good toughness, adjustability, portability, safety, reliability, and easy carrying. They are ideal tools for electricians climbing various sizes of concrete or wooden poles. Power workers often use foot straps in conjunction with safety ropes when climbing concrete poles to ensure safety.

[0003] However, the existing foot catch has a first buckle and a second buckle. The second buckle is fixed to the foot pedal, and the power worker's foot is fixed to the foot pedal. By standing on the foot pedal, the first buckle and the second buckle are locked onto the surface of the utility pole by strong friction. As the power worker climbs up or down, he alternately lifts his feet, which causes the foot catch to lock onto the utility pole, thus moving on the surface of the utility pole.

[0004] The current foot pedal structure mainly includes a pedal fixed to the first buckle, and a buckle fixed to the upper surface of the pedal for securing the pedal to the worker's foot. The buckle is usually only fixed to the forefoot of the worker. When in use, the worker's foot pulls the buckle up to climb. Because the buckle only secures the forefoot of the worker, there is a risk that the buckle will come off the foot during the climb, causing the worker to fall from a height. Utility Model Content

[0005] The present invention aims to provide a climbing device for power transmission line construction, which is mainly used to solve the technical problem that the straps may come off the feet during the climbing process, causing workers to fall from heights.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] A climbing device for power transmission line construction includes a first buckle and a second buckle for jointly gripping the surface of a utility pole. A footboard is installed on the first buckle, and a first strap is provided on the footboard for fixing the worker's forefoot to the footboard. A second strap is also provided on the footboard for fixing the worker's foot to the footboard. The second strap includes a first strap close to the heel. An adjustment device is also provided on the footboard to adjust the distance between the first strap and the footboard to control the tightness between the worker's foot and the footboard.

[0008] The beneficial effects of this utility model are as follows:

[0009] The electrician wears the second buckle on his ankle, with the ball of his foot passing through the space formed by the first buckle and the pedal. Then, by adjusting the device, the distance between the first strap and the pedal is shortened, causing the worker's foot to move forward and the instep to be close to the first buckle. The first buckle and the first strap together clamp the foot, making the foot firmly fixed to the pedal. This solves the technical problem in existing technologies where the buckle may detach from the foot during climbing, causing the worker to fall from a height.

[0010] Meanwhile, to ensure foot comfort while climbing utility poles, workers need to tiptoe on the footboard, meaning their heels cannot be completely fixed to the footboard. Otherwise, they may experience foot discomfort and be unable to properly test the foot straps and the point of contact with the utility pole, posing a safety hazard. The adjustment device can either reduce or increase the distance between the first strap and the footboard, allowing workers to tiptoe on the footboard.

[0011] Preferably, the second buckle further includes a second strap, the two ends of which are fixedly connected to the two ends of the first strap, and the first strap contacts the worker's instep. In this design, the first strap and the second strap form a loop and are fitted around the ankle, ensuring that the second strap remains in contact with the heel regardless of movement.

[0012] Preferably, the adjusting device includes a sliding plate, a pressure rod, and a traction belt;

[0013] The pedal is hollow inside, and the sliding plate is slidably connected inside the pedal. The height of the upper surface of the sliding plate near the first buckle is less than the height of the end away from the first buckle.

[0014] The upper surface of the pedal has an installation opening that matches the pressure plate and is located at the worker's heel. One end of the pressure rod is inserted into the pedal through the installation opening; the end of the pressure rod inserted into the pedal can contact the upper surface of the sliding plate.

[0015] The upper surface of the pedal has a strip-shaped hole. One end of the traction belt is fixed to the end of the first strap, and the other end passes through the strip-shaped hole into the pedal and is fixed to both sides of the sliding plate.

[0016] In this design, when the worker's heel is on the pedal, the pressure plate is pressed down. The end of the pressure plate inside the pedal contacts the inclined upper surface of the sliding plate, which then moves towards the first buckle, thereby driving the traction belt to move. This causes the first strap to move towards the first buckle and the pedal, pushing the worker's heel forward so that the sole of the foot is firmly pressed against the pedal, preventing the foot from detaching from the pedal. Furthermore, the pressure of the first strap on the heel when the worker's heel is fully pressed down can be controlled by adjusting the length of the traction belt or the inclination angle of the upper surface of the sliding plate.

[0017] When a worker needs to stand on tiptoe, they lift their heels, and the traction belt moves the sliding plate in the opposite direction, releasing the pressure of the first belt on the foot. At this time, the worker can easily lift their heels.

[0018] Preferably, the end of the pressure plate furthest from the sliding plate is fixedly connected to a limiting plate to prevent the pressure rod from retracting completely into the pedal. In this design, the limiting plate serves two purposes: firstly, it prevents the pressure plate from retracting completely into the pedal; secondly, the limiting plate always protrudes from the surface of the sliding plate, increasing the presence of the pressure rod. Workers can clearly feel the presence of the limiting plate when stepping down, and can press firmly on it to tighten the first strap. Furthermore, the limiting plate also increases friction, providing an anti-slip effect.

[0019] Preferably, the end face of the pressure plate located inside the pedal is rounded, and the diameter of the end face is larger than the width of the mounting opening. In this design, the rounded end of the pressure plate allows the end of the pressure plate to make line contact with the inclined surface of the sliding plate, reducing the friction between the pressure plate and the sliding plate, making it easier for the pressure plate to slide on the surface of the sliding plate, thereby driving the sliding plate to move; the larger diameter of the end face prevents the pressure plate from completely disengaging from the pedal.

[0020] Preferably, a slide rod is fixed inside the pedal near the first buckle, the slide rod passes through the pressure plate, and the pressure plate can slide on the slide rod. In this design, the slide rod is used to limit the sliding direction of the sliding plate.

[0021] Preferably, a plurality of ball bearings are rotatably connected to the bottom surface of the pedal, and the ball bearings contact the lower surface of the sliding plate. In this design, the ball bearings provide support for the sliding plate and reduce the frictional force of the sliding plate sliding inside the pedal.

[0022] Preferably, a spring is fitted onto the sliding rod, with one end of the spring fixedly connected to the sliding plate and the other end connected to the side wall of the pedal. In this design, the spring provides a certain tension, ensuring that the second buckle and limiting plate remain close to the worker's foot whether the worker is tiptoeing or stepping down, moving with the foot's movement and responding promptly to foot actions.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] like Figure 1 As shown, a climbing device for power transmission line construction includes a first buckle 11 and a second buckle 12 for jointly gripping the surface of a utility pole. The second buckle 12 can slide relative to the first buckle 11 and can be positioned. A footboard 2 is installed on the first buckle 11. A first strap 3 for fixing the worker's forefoot to the footboard 2 is provided on the footboard 2. The length of the first strap 3 is adjustable to accommodate different foot sizes. A second strap for fixing the worker's foot to the footboard 2 is also provided on the footboard 2. The second strap includes a first band 41 close to the heel and a second band 42. The two ends of the second band 42 are fixedly connected to the two ends of the first band 41, and the first band 41 contacts the worker's instep. The first band 41 and the second band 42 form a loop that is fitted around the ankle, so that the second band 42 can always contact the heel no matter how it moves.

[0029] The pedal 2 is also equipped with an adjustment device that adjusts the distance between the first strap 41 and the pedal 2 to control the tightness between the worker's foot and the pedal 2. The adjustment device can not only reduce the distance between the first strap 41 and the pedal 2 to tighten the foot, but also increase the distance between the first strap 41 and the pedal 2, so that the worker can tiptoe on the pedal 2.

[0030] like Figure 2 , 3 As shown, the adjusting device includes a sliding plate 6, a pressure rod, and a traction belt 43;

[0031] The pedal 2 is hollow inside, and the sliding plate 6 is slidably connected inside the pedal 2. A sliding rod 71 is fixed inside the pedal 2 near the first buckle 3. The sliding rod 71 passes through the pressure plate 5, and the pressure plate 5 can slide on the sliding rod 71. Several balls are rotatably connected to the bottom surface inside the pedal 2. The balls contact the lower surface of the sliding plate 6, which can support the sliding plate 6 and reduce the friction of the sliding plate 6 sliding inside the pedal 2. A spring 71 is sleeved on the sliding rod 71. One end of the spring 71 is fixedly connected to the sliding plate 6, and the other end is fixedly connected to the side wall of the pedal 2, so that the sliding plate 6 has a tendency to slide towards the first buckle 3. The height of the upper surface of the sliding plate 6 near the first buckle 3 is less than the height of the end away from the first buckle 3, that is, the upper surface of the sliding plate 6 is inclined.

[0032] The upper surface of the pedal 2 has an installation opening that matches the pressure plate 5 and is located at the worker's heel. One end of the pressure rod is inserted into the pedal 2 through the installation opening and contacts the upper surface of the sliding plate 6. The end face of the pressure plate 5 inside the pedal 2 is rounded, and the diameter of the end face is larger than the width of the installation opening. The rounded end of the pressure plate 5 allows the end of the pressure plate 5 to make line contact with the inclined surface of the sliding plate 6, reducing the friction between the pressure plate 5 and the sliding plate 6, making it easier for the pressure plate 5 to slide on the surface of the sliding plate 6, thereby driving the sliding plate 6 to move; the end face diameter is relatively large. It can prevent the pressure plate 5 from completely disengaging from the pedal 2; the end of the pressure plate 5 away from the sliding plate 6 is fixedly connected to a limiting plate 51 to prevent the pressure rod from completely retracting into the pedal 2. On the one hand, this prevents the pressure plate 5 from completely retracting into the pedal 2. On the other hand, the limiting plate 51 always protrudes from the surface of the sliding plate 6, which can increase the presence of the pressure rod. The worker can clearly feel the presence of the limiting plate 51 when stepping down and can step on the limiting plate 51 to tighten the first strap 41. Furthermore, the setting of the limiting plate 51 can also increase the friction and play a role in preventing slippage.

[0033] The upper surface of the pedal 2 has a strip-shaped hole 21. One end of the traction belt 43 is fixed to the end of the first bundle 41, and the other end passes through the strip-shaped hole 21 into the interior of the pedal 2 and is fixed to both sides of the sliding plate 6. Each end of the first bundle 41 is fixed with three traction belts 43. The sliding plate 6 has protrusions fixed to both sides. The end of the traction belt 43 away from the first bundle 41 is wrapped and fixed to the protrusion.

[0034] When the worker's heel is on the pedal 2, the pressure plate 5 is pressed down. The end of the pressure plate 5 inside the pedal 2 contacts the inclined upper surface of the sliding plate 6. The sliding plate 6 then moves towards the first buckle 3, thereby driving the traction belt 43 to move. This causes the first strap 41 to also move towards the first buckle 3 and the pedal 2, pushing the worker's heel forward so that the sole of the foot is firmly pressed against the pedal 2, preventing the foot from detaching from the pedal 2. Furthermore, the pressure of the first strap 41 on the heel when the worker's heel is fully pressed down can be controlled by adjusting the length of the traction belt 43 or the inclination angle of the upper surface of the sliding plate 6.

[0035] When a worker needs to stand on tiptoe, he lifts his heel, and the traction belt 43 drives the sliding plate 6 to move in the opposite direction, releasing the pressure of the first belt 41 on the foot. At this time, the worker can easily lift his heel.

[0036] As can be seen from the above, the technical principle of this utility model is as follows:

[0037] The electrician wears the second buckle on his ankle, with the ball of his foot passing through the space formed by the first buckle 3 and the pedal 2, and his heel placed above the pressure bar. During the climb, if the heel steps down on the limiting plate 51, the pressure plate 5 will be pressed down. The end of the pressure plate 5 inside the pedal 2 contacts the inclined upper surface of the sliding plate 6, and the sliding plate 6 will move towards the first buckle 3, thereby driving the traction belt 43 to move. This will cause the first strap 41 to also move towards the first buckle 3 and the pedal 2, pushing the worker's heel forward so that the ball of the foot is firmly attached to the pedal 2, preventing the foot from detaching from the pedal 2. The pressure of the first strap 41 on the heel when the worker's heel is fully pressed down can be controlled by adjusting the length of the traction belt 43 or the inclination angle of the upper surface of the sliding plate 6.

[0038] When a worker needs to stand on tiptoe, he lifts his heel, and the traction belt 43 drives the sliding plate 6 to move in the opposite direction, releasing the pressure of the first belt 41 on the foot. At this time, the worker can easily lift his heel.

[0039] The above descriptions are merely embodiments of this utility model, and common knowledge regarding specific structures and characteristics is not elaborated upon here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model. These modifications will not affect the effectiveness of the implementation of this utility model or the practicality of the patent. The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
