Description

Technical Field

[0001] This utility model relates to the field of utility pole technology, specifically an improved utility pole climbing device. Background Technology

[0002] As the name suggests, a utility pole is a pole used to carry power lines. They can be found in rural areas, fields, roads, and streets. They were one of the important infrastructures in early China. When utility poles are in use, climbing devices are needed to facilitate the maintenance of power lines.

[0003] Existing pole-climbing devices require the body to exert force outwards and downwards to secure the pole. When people are afraid, they tend to get closer to and hug the pole, inevitably leading to falls and injuries. The usage techniques are not based on conventional thinking. The pole is slippery even with slight dirt or moss. If a worker suddenly loses consciousness while climbing, they will inevitably lose their grip and fall, resulting in injury. The double safety rope can only be secured at the top, relying on the balls of the feet for support. Standing for long periods of time is particularly tiring and prone to accidents. There is only one strap securing the feet, which is not safe enough. The diameter of the pole gradually decreases from bottom to top. Every one or two steps, the traditional device requires manual readjustment of the device opening size to match the pole's thickness. The method of adjustment is based on guesswork. If the guess is wrong, at best, readjustment is required, and at worst, a fall and injury will occur.

[0004] Therefore, those skilled in the art have provided an improved pole climbing device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide an improved pole climbing device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An improved utility pole climbing device includes a triangular support pole, and an improved mechanism is provided on the outside of the triangular support pole;

[0008] The improved mechanism includes a main rod located above a triangular support rod. A transmission rod is rotatably connected inside the main rod, with its bottom end fixedly connected to the upper surface of the triangular support rod. A ratchet is fixedly connected to the top end of the transmission rod. A pawl is rotatably connected inside the main rod, and an auxiliary rod is fixedly connected to the outer surface of the pawl. Both ends of the auxiliary rod penetrate the main rod and extend to its sides. A fixing pin is fixedly connected to the left side of the main rod. A locking spring is fixedly connected to the outer surfaces of the auxiliary rod and the fixing pin. A wire sleeve is positioned above the triangular support rod, with an unlocking wire slidably connected inside the wire sleeve. The end of the unlocking wire near the auxiliary rod is fixedly connected to the outer surface of the auxiliary rod. A tapered through-hole unlocking device is fitted onto the outer surface of the unlocking wire. A foot pedal is fixedly connected to the right side of the main rod, with a first strap fixedly connected to its upper surface. A second strap, a third strap, and a connecting block are fixedly connected to the outer surface of the main rod, with a first anti-slip rubber layer inside the connecting block.

[0009] As a further improvement of this utility model: an auxiliary bearing is sleeved on the outer surface of the transmission rod, and the auxiliary bearing is embedded inside the main rod.

[0010] As a further improvement of this utility model: a rotating bearing is fitted on the outer surface of the pawl, and the rotating bearing is embedded inside the main rod.

[0011] As a further improvement of this utility model: a reinforcing ring is fixedly connected to the outer surface of the fixing nail, and the right end of the reinforcing ring is fixedly connected to the left side of the main rod.

[0012] As a further improvement of this utility model: the outer surface of the unlocking wire is threaded with a limit screw, and the inner wall of the triangular rod is fixedly connected with a second anti-slip rubber.

[0013] As a further improvement of this utility model: the right end of the conical central unlocking device is fixedly connected to a retaining ring, and the inner wall of the retaining ring is fixedly connected to the outer surface of the wire sleeve.

[0014] As a further improvement of this utility model: the connecting block has two fixing bolts that slide inside, and the bottom end of each fixing bolt passes through the first anti-slip rubber and is threadedly connected to the first anti-slip rubber.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This utility model, by incorporating a triangular pole, main pole, transmission rod, ratchet, pawl, auxiliary rod, fixing nail, locking spring, steel wire sleeve, unlocking steel wire, conical central unlocking device, foot pedal, first strap, second strap, third strap, connecting block, and first anti-slip rubber, conforms to conventional human thinking. It allows the user to approach and grip the utility pole, applying downward force for stable support. The user's weight is amplified by the lower foot pedal, creating a lever effect for enhanced stability. This stability is further strengthened by applying even more force downwards to the foot pedal. The lower leg and foot are secured with the first, second, and third straps respectively, maintaining a fixed position even in unconsciousness, preventing falls and facilitating accident rescue. The foot pedal provides support for the middle of the foot, making prolonged standing more comfortable and ergonomic. The ratchet controls the unidirectional movement of the pole; by swinging the foot towards the pole, the pole grips tightly. It automatically adapts to gradually thinning poles, eliminating guesswork and manual adjustment, effectively improving the safety and applicability of the utility pole climbing device.

[0022] Please see Figure 1-4 An improved utility pole climbing device includes a triangular support pole 1, and an improved mechanism 2 is provided on the outside of the triangular support pole 1.

[0023] The improved mechanism 2 includes a main rod 201, which is located above the triangular support rod 1. A transmission rod 202 is rotatably connected inside the main rod 201. The bottom end of the transmission rod 202 is fixedly connected to the upper surface of the triangular support rod 1. An auxiliary bearing 3 is sleeved on the outer surface of the transmission rod 202 and is embedded inside the main rod 201. The auxiliary bearing 3 can reduce the friction generated by the transmission rod 202 when rotating, making the transmission rod 202 more sensitive when rotating, and also reducing the wear rate of the transmission rod 202 and increasing the service life of the transmission rod 202.

[0024] A ratchet 203 is fixedly connected to the top of the transmission rod 202. A pawl 204 is rotatably connected inside the main rod 201. An auxiliary rod 205 is fixedly connected to the outer surface of the pawl 204. A rotating bearing 4 is sleeved on the outer surface of the pawl 204 and is embedded inside the main rod 201. The rotating bearing 4 can reduce the friction generated by the pawl 204 when rotating, making the pawl 204 more sensitive when rotating, and also reducing the wear rate of the pawl 204 and increasing the service life of the pawl 204.

[0025] The auxiliary rod 205 extends through the main rod 201 to both sides of the main rod 201 at both ends. A fixing nail 206 is fixedly connected to the left side of the main rod 201. A locking spring 207 is fixedly connected to the outer surfaces of the auxiliary rod 205 and the fixing nail 206. A reinforcing ring 5 is fixedly connected to the outer surface of the fixing nail 206. The right end of the reinforcing ring 5 is fixedly connected to the left side of the main rod 201. The reinforcing ring 5 can increase the fixed connection area between the fixing nail 206 and the main rod 201, making the connection between the two more secure, preventing the fixing nail 206 from loosening after long-term use, and increasing the durability of the device.

[0026] A wire sleeve 208 is provided above the triangular support rod 1. An unlocking wire 209 is slidably connected inside the wire sleeve 208. A limit screw 6 is threadedly connected to the outer surface of the unlocking wire 209. A second anti-slip rubber 8 is fixedly connected to the inner wall of the triangular support rod 1. The limit screw 6 can provide a blocking position for the unlocking wire 209, providing assistance for subsequent operations. The second anti-slip rubber 8 can increase the stability of the triangular support rod 1 during use.

[0027] One end of the unlocking wire 209 near the auxiliary rod 205 is fixedly connected to the outer surface of the auxiliary rod 205. A tapered central unlocking device 210 is sleeved on the outer surface of the unlocking wire 209. A retaining ring 7 is fixedly connected to the right end of the tapered central unlocking device 210. The inner wall of the retaining ring 7 is fixedly connected to the outer surface of the wire sleeve 208. The retaining ring 7 can fix the wire sleeve 208 and the tapered central unlocking device 210, increasing the ease of pulling the tapered central unlocking device 210.

[0028] A foot pedal 211 is fixedly connected to the right side of the main rod 201. A first strap 212 is fixedly connected to the upper surface of the foot pedal 211. A second strap 213, a third strap 214, and a connecting block 215 are fixedly connected to the outer surface of the main rod 201. A first anti-slip rubber 216 is provided inside the connecting block 215. Two fixing bolts 9 are slidably connected inside the connecting block 215. The bottom end of each fixing bolt 9 passes through the first anti-slip rubber 216 and is threadedly connected to the first anti-slip rubber 216. The fixing bolts 9 can lock the position of the first anti-slip rubber 216 and the connecting block 215, increasing the stability of the first anti-slip rubber 216 in use and improving the stability of the device in use.

[0029] The working principle of this utility model is as follows: In use, place the middle of your foot above the foot pedal 211, then secure your foot with the first strap 212, and further secure your ankle and lower leg with the second strap 213 and third strap 214. Then, push the conical central unlocking device 210, causing it to move the unlocking wire 209 within the wire sleeve 208, and causing one end of the auxiliary rod 205 to move downwards and the other end upwards. The auxiliary rod 205 then moves the pawl 204, releasing it from the lock on the ratchet 203. At this point, swing the triangular lever 1 outwards, causing it to rotate outwards via the transmission rod 202, simultaneously rotating the ratchet 203. After adjustment, release the conical central unlocking device 210. The extension and retraction of the locking spring 207 will then reset the auxiliary rod 205. The pawl 204 then locks the position of the ratchet 203 again. When climbing the utility pole, the triangular support 1 and the main pole 201 are moved to the outside of the pole, and then the triangular support 1 is swung inward. At this time, the triangular support 1 will rotate with the transmission rod 202 and contact the utility pole. At the same time, the ratchet 203 and the pawl 204 work together to prevent the triangular support 1 from rotating outward, thus ensuring the self-locking ability and preventing danger during use. It automatically adapts to gradually thinning utility poles without guessing or manual adjustment. Since the diameter of the utility pole gradually decreases from bottom to top, it can effectively adapt to the device. During the worker's climb, the weight of the human body is concentrated on the lower foot pedal 211, thus forming a lever principle and obtaining more stable support. In addition, multiple straps can effectively increase the safety and comfort of the worker during use.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
