[0032] The embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0033] Example 1

[0034] See Figures 1-7 As shown, the electric climbing device includes:

[0035] Two hanging points 11 are fitted onto the outside of the pole, and each of the two hanging points 11 is provided with a hook 12;

[0036] Two hanging ropes 41 are provided, the top ends of which are connected to two hooks 12. Each of the two hanging ropes 41 is equipped with a foot buckle 51 at its bottom end. The hanging ropes 41 are made of ropes with a diameter of 20 mm and a tensile strength greater than 2206 N. The safety hook at the hanging point is a self-locking hook.

[0037] A fall arrestor 31 is installed on the outside of the two hanging ropes 41;

[0038] A safety belt 21 is used to fasten around the user's waist. Two belt buckles 22 are connected to the safety belt 21, and the two belt buckles 22 are connected to a fall arrestor 31.

[0039] In this embodiment, there are two foot buckles 51, used by the left and right feet respectively, and foot buckle 11 (stirrup). The upper hanging ring is the center of gravity of the foot (about 10 mm inside the instep), and the bottom is the human body's habitual pressure point. The heel support ring and the front upright ring are used to fix the shoelaces and make arc-shaped contact with the pole. It is made of 8 mm diameter "Grade IV" steel bars (540 / 835 grade) (spot welded at the double reinforcement, and finally quenched to increase strength).

[0040] In this embodiment, each of the two foot buckles 51 is provided with a foot buckle ring 52 at its top, and the two foot buckle rings 52 are connected to the bottom ends of the two hanging ropes 41.

[0041] In this embodiment, the fall arrestor 31 includes two fall arrestor boxes 312, and two rope holes 311 are fixedly installed on the inner side of the two fall arrestor boxes 312, and two ropes 41 pass through the two rope holes.

[0042] The anti-fall lock box 312 is made of welded steel tube and flat iron; the opening and parts are processed to ensure the locking relationship between the ratchet 313 and the ratchet lock 316.

[0043] In this embodiment, ratchet 313 is rotatably installed inside both of the two fall arrestor lock boxes 312, and ratchet safety belt connecting rings 315 are provided on the outer side of both ratchet 313. The two waist belt buckles 22 are connected to the two ratchet safety belt connecting rings 315.

[0044] The inner cam portion of the ratchet 313 is drilled to fit the anti-fall lock box 312, and the cam portion is machined by hand filing; the ratchet 313 portion can be machined by hand filing (or sawing) and is machined in conjunction with the ratchet lock 316. The ratchet 313 is made of aluminum alloy (or high-strength engineering plastic).

[0045] In this embodiment, each of the two fall arrestor lock boxes 312 is provided with a ratchet shaft 314, and the two ratchet wheels 313 are rotatably connected through the two ratchet shafts 314. Each of the two ratchet shafts 314 is provided with a ratchet shaft pin hole 318. The two ratchet locks 316 are rotatably installed in the two fall arrestor lock boxes 312. Each of the two ratchet locks 316 is provided with a ratchet lock notch 317, and the ratchet lock notch 317 cooperates with the corresponding ratchet wheel 313.

[0046] In this embodiment, the assembly of the fall arrestor lock 31 includes the following steps:

[0047] First, the ratchet lock 316 is inserted into the anti-fall lock box 312, installed on the left and right sides respectively. After the ratchet 313 is inserted, the ratchet lock 316 is fixed (cannot be pulled out).

[0048] Second, ratchet 313 is placed into the anti-fall lock box 312. Ratchet 313 must cooperate with ratchet lock 316 to unlock by gravity (the left and right sides cannot be installed backwards).

[0049] Third, the ratchet shaft 314 is inserted into the lock box for fixation.

[0050] Fourth, the cotter pin is inserted into the ratchet shaft pin hole 318 on the ratchet shaft 314 for locking.

[0051] In operation, (1) single-leg climbing operation (rapid climbing, such as climbing with the left leg), the operator locks the fall arrestor 3 on the right side. The cam groove of the ratchet 313 locks the hanging point rope. The fall arrestor 3 hangs down automatically due to gravity. The ratchet 313 is automatically unlocked when it is lifted. The ratchet lock 316 is in the unlocking direction because the handle counterweight is in the unlocking direction. The center of gravity moves to the right side. The climber lifts the left leg and pushes the hanging point 11 to the left and pulls it up to test its reliability. The left leg is raised. If climbing is completed by climbing stairs, push the hanging point 11 to the right and pull it up to test its reliability. This completes one lifting process. Repeat this process multiple times until the working height is reached to complete the climbing. The operation is reversed to achieve descent.

[0052] (2) Two-legged climbing operation, using equipment poles or obstacle poles. The operator unlocks the fall arrestor 3, and the ratchet 313 automatically unlocks when lifted. Because the handle counterweight of the ratchet lock 316 is in the unlocking direction, the operator opens the large hook of the left hook point 11 on one side, lifts one leg to the left, selects an obstacle-free position, and locks the large hook of hook point 11 automatically. The operator then pulls the hook to check that the opening of the large hook is outward and upward, and the operator raises one leg to the left to complete the climbing. The operator opens the large hook of the right hook point 11 on one side, lifts one leg to the right, selects an obstacle-free position, locks the hook of hook point 11, and pulls the hook. The opening of the large hook is outward and upward, and the operator raises one leg to the right to complete one climbing. Repeat this process multiple times until the working height is reached to complete the climbing. The operation is reversed to achieve descent.

[0053] In this embodiment, the worker selects a suitable position (with both anchor points close together), keeps their heels together and legs straight, lifts the "fall arrestor" higher than the safety belt (automatic locking) with their hands, relaxes their waist by leaning back, and uses the safety belt to pull the "fall arrestor" downward to strengthen the lock. They then rotate the left and right "ratchet locks" to lock the anchor point rope. The two feet (anchors), safety belt, and anchor point rope form a five-point positioning system (the safety belt is tied below the waist, as if sitting on a platform). The worker can then carry out maintenance operations on the power pole.

[0054] In this embodiment, a double-anchor point safety harness is used. After the worker lifts the "fall arrestor" higher than the safety harness, they apply force and rotate the left and right "ratchet locks" to lock it. The double-anchor point rope and the safety belt (including the "fall arrestor") form an "inverted three-point" double-hook safety harness, transferring the weight of the body to the legs, achieving the effect of a five-point safety harness, which can reduce the counterweight of the worker at height.

[0055] Example 2

[0056] See Figures 8-9 As shown, a working process for an electric climbing device is also proposed, including the following two climbing methods:

[0057] See Figure 8 Climbing on one leg:

[0058] A1: Prepare for a single-leg ground position, turn the fall arrestor on 1st open, 2nd closed, and 4th locked;

[0059] A2: Raise one leg, lift the left leg G, push the hanging point D to raise the hanging rope 5;

[0060] A3: Single leg lift, A fall arrestor lift, G left leg lift, G right leg lift;

[0061] A4: Single-leg ascent. After the body rises, push the hook at point E to approach the hook at point D. The rope at point 6 will be under force, thus completing the single-leg ascent.

[0062] See Figure 9 Climbing with both legs:

[0063] S1: Raise both legs, encounter an obstacle, open ratchet locks 1 and 2, lift the right leg H and attach to point E, rope 6 is under force, pull the right rope with your right hand and raise the leg;

[0064] S2: Platform operation, with both heels close together and pressed against the pole, after the fall arrest lock A is raised, ratchet lock 1 is open and 2 is closed; lean back and relax your waist F, and you can start working;

[0065] S3: Dual attachment point safety belt, anti-fall lock self-locking after lifting, ratchet lock 3-way and 4-way;

[0066] S4: Ratchet lock 3 hangs down naturally due to gravity. Left lock 1 automatically unlocks because the weight of the fall arrestor lock is lower than the waist belt. The hanging rope 5 can move on the ratchet lock. The ratchet 2 is turned by hand to make the ratchet engage with the ratchet lock. The tension of the hanging rope 6 is used to lock it. The ratchet lock automatically unlocks when it is lower than the safety belt and automatically locks when it is higher than the safety belt. The safety belt automatically locks when it accelerates down.

[0067] This utility model is not limited to the above-described preferred embodiment. Anyone can derive other products in various forms under the guidance of this utility model. However, regardless of any changes made in its shape or structure, any technical solution that is the same as or similar to this utility model is within its protection scope.
