Description

Technical Field

[0001] The utility model relates to the field of electrician tools, in particular to a pole climbing auxiliary device. Background Art

[0002] When performing aerial work on a utility pole, an auxiliary device for climbing the pole is generally used. The most common auxiliary device is the climbing foot buckle worn by the technician, which uses the lever principle to hold the pole tightly to achieve the effect of assisting pole climbing. Since the relative angle between the movable hook and the pedal of the conventional climbing foot buckle is basically fixed, the technician's feet will be at a constant angle for a long time when working after climbing the pole, which is easy to cause discomfort. In addition, when the climbing foot buckle holds the pole tightly, it is difficult to adjust the distance between the two friction blocks holding the pole tightly. When climbing the pole, the climbing foot buckle is not easy to immediately loosen or hold the pole tightly, which affects the speed of climbing the pole. Utility Model Content

DETAILED DESCRIPTION

[0026] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0027] Example:

[0028] like Figure 1-Figure 5As shown, a pole climbing auxiliary device includes a pair of symmetrically arranged foot buckles, the foot buckles include a foot pedal 100, an outer fastener and an inner fastener, the foot pedal 100 includes a pedal plate 110 and a mounting frame 120, the mounting frame 120 is a hollow frame body that penetrates laterally, a rotating shaft 130 is provided in the middle of the bottom of the pedal plate 110, an axial hole is provided in the middle of the top of the mounting frame 120, the rotating shaft 130 is arranged through the axial hole, the pedal plate 110 includes a bottom plate 111 and side plates 112 arranged on both sides of the bottom plate 111, a first strap 140 for binding the foot is provided on the top side of the pedal plate 110, and holes can be opened on the side plates 112 for connecting the two ends of the first strap 140;

[0029] The inner fastener includes a buckle block 210, a gear 220 and a rack 230. The gear 220 is sleeved at the end of the rotating shaft 130. The rack 230 is meshed and arranged on one side of the gear 220 along the direction in which the mounting frame 120 passes through, and is in contact with the side wall of the mounting frame 120. A limit frame 240 is provided on one side of the tooth surface of the rack 230. The limit frame 240 includes two limit blocks and a connecting strip. The two limit blocks are respectively arranged at both ends of the rack 230 vertically. The length of the limit blocks is greater than the diameter of the gear 220. The two ends of the connecting strip are respectively connected to the side of the two limit blocks away from the rack 230. The side of the connecting strip away from the rack 230 is in contact with the inner wall of the mounting frame 120. The frame 240 can limit the movement of the rack 230 to prevent the rack 230 from being separated from the installation frame 120, and at the same time fit with one side of the inner wall of the installation frame 120, cooperate with the fit of the rack 230 with the inner wall of the installation frame 120 to limit the rack 230 laterally, thereby improving the stability of the structure; the buckle block 210 includes a clip 211 and a connecting piece 212, the clip 211 includes two pieces, symmetrically connected to the upper and lower sides of one of the limiting blocks away from the gear 220, one side of the connecting piece 212 is arranged between the clips 211 in the middle, and the overlapping part of the clip 211 and the connecting piece 212 is penetrated and connected with a bolt, and after loosening the bolt, the connecting piece 212 can rotate relative to the clip 211;

[0030] The outer fastener includes a fastener body 310 and a movable hook 320. The fastener body 310 is a curved rod, one end of which is welded to the bottom of the installation frame 120, and the other end is provided with a connecting sleeve 330. The movable hook 320 includes an integrally formed straight section and a curved section. The connecting sleeve 330 is sleeved on the outer side of the straight section of the movable hook 320. The end of the straight section of the movable hook 320 is limited by a limiting member 340. The limiting member 340 can be a rivet riveted to the straight section of the movable hook 320. The inner side of the curved section of the movable hook 320 is connected to the installation frame 120. The side where the upper buckle block 210 is located is opposite, that is, the inner side of the curved section of the movable hook 320 and the surface opposite to the buckle block 210 form a clamping surface for clamping the electric pole. The inner side of the curved section of the movable hook 320 and the buckle block 210 are respectively provided with friction blocks 400 to increase friction and facilitate clamping the electric pole. The friction block 400 can be made of rubber material. When actually installing the friction block 400, holes can be opened on the movable hook 320, the connecting plate 212 and the friction block 400 respectively, and the friction block 400 is connected by bolts.

[0031] The working principle of the above technical solution is as follows:

[0032] Before climbing the pole, the technician can place the pedal plate 110 on the sole and fix it with the first strap 140. Under the premise of keeping the outer fastener and the mounting frame 120 stationary, the pedal plate 110 is rotated to drive the gear 220 to rotate and move the meshing rack 230 through the rotating shaft 130, so as to realize the approach and separation of the buckle block 210 and the movable hook 320. When climbing the pole, one of the feet can be slightly lifted up so that the buckle block 210 on one side of the mounting frame 120 is loose relative to the pole, and at the same time, the movable hook 320 is kept close to the pole, so as to facilitate the foot to apply force when rotating the pedal plate 110. After rotating the pedal plate 110, the buckle block 210 is away from the movable hook 320, so as to facilitate the quick separation of the foot buckle from the pole, and the foot can be lifted to a higher place, so as to similarly make the movable hook 320 close to the pole, and the pedal is rotated in the opposite direction so as to make the buckle block 210 close to the movable hook 320, so as to facilitate the foot buckle to quickly hold the pole tightly. When working for a long time, the pedal can also be rotated in the above manner to adjust the angle of the foot to avoid discomfort caused by the foot being at a constant angle for a long time during work.

[0033] In another embodiment, the rack 230 is disposed on one side of the mounting frame 120 close to the extending direction of the buckle body 310, that is, on the front side close to the corresponding stepping position of the pedal 110. This arrangement allows the buckle block 210 to approach the movable hook 320 when the technician's foot turns inward, and vice versa, away from the movable hook 320, which is in line with user habits.

[0034] In another embodiment, if Figure 1 and Figure 4As shown, the device includes a second strap 500, a connecting buckle 510 is provided at the end of the second strap 500, a connecting belt 520 connected to the foot buckles is provided on the second strap 500, a connecting ring 350 is provided on the bottom side of the buckle body 310, and the end of the connecting belt 520 surrounds the buckle body 310 and passes through the connecting ring 350 to be connected to the buckle body 310.

[0035] The foot buckle can be connected to the technician through the second strap 500. If the first strap 140 loosens and causes the foot buckle to slip, it can prevent the foot buckle from falling from a high place; the connecting ring 350 can laterally limit the connection position of the connecting belt 520 to prevent the connection position of the connecting belt 520 from being changed at will.

[0036] In another embodiment, if Figure 5 As shown, foam pads 113 are respectively provided on the opposite surfaces of the side panels 112. The foam pads 113 on the pedal plate 110 further reduce the discomfort caused by the squeeze of the side panels 112 to the technicians.

[0037] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
