Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary tools for climbing electric poles, in particular to a climbing device for electric wire installation. Background Art

[0002] When maintaining the circuit contact network, it is necessary to climb the electric pole; the anti-skid foot buckles are used to climb the poles so as to maintain the power equipment on the poles; the sizes of the existing anti-skid foot buckles are fixed and can only be used to climb poles of a certain size. When the sizes of the poles are different, the anti-skid foot buckles of fixed sizes cannot be used any more.

[0003] According to the anti-skid foot buckle for climbing railway contact network pillars with publication number CN213724717U and the foot buckle for preventing falling off from the electric pole with publication number CN208877843U, adjustable movable claws are designed to adapt to columns of different diameters; however, the technology involved in the above-mentioned public documents has the problem that the movable claw adjustment operation is not convenient and the locking ability of the movable claw is poor, which is prone to safety hazards when the operator uses it. In particular, the movable claw and the pedal part in the foot buckle for preventing falling off from the electric pole with publication number CN208877843U are only fixed by the spring to the movable claw to achieve the relative position of the two; if the elastic force of the spring fails and the connection between the spring and the movable claw or the pedal part fails; the distance between the movable claw and the pedal part will instantly increase, causing the movable claw and the pedal part to be unable to be firmly stuck on the electric pole, thereby causing the staff to fall from the electric pole.

Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention to be protected, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Example 1

[0024] Please refer to Figure 1-Figure 3 shown.

[0025] The utility model provides a climbing device for installing electric wires, which mainly solves the problem that the size of the anti-skid foot buckles in the prior art is fixed and can only be used for climbing columns of a certain size. When the size of the columns is different, the anti-skid foot buckles of fixed size cannot be used. Although the anti-skid foot buckles are adjustable, the structure involved in the existing scheme is easy to cause safety accidents, and the existing structure also has the problems of inconvenient adjustment operation of the movable claw and poor locking ability of the movable claw. In order to solve the above problems, the set foot pedal 1 fits the shape of the human foot and can provide a wider stepping area for the user. The material of the set foot pedal 1 is a steel plate, and a rubber plate is bonded to the steel plate by gluing to increase the friction between the sole and the steel plate to ensure the stability of the device when in use. The fixed caliper 6 is fixed to the front end of the foot pedal 1, and the fixed caliper 6 has an arc section and a fixed section, and the fixed section and the arc section are integrally formed. The fixed section of the fixed caliper 6 is fixed to the lower side wall of the foot pedal 1 by bolts. The movable caliper 3 is slidably set on the lower side wall of the foot pedal 1, and the movable caliper 3 and The fixed caliper 6 is enclosed to form a clamping area for clamping cylindrical columns such as electric poles; a notch is provided at the front end of the foot pedal 1, and an adjusting member 9 is rotatably arranged in the notch, and a transmission mechanism is arranged between the adjusting member 9 and the non-clamping end of the movable caliper 3; after such arrangement, the user steps on the adjusting member 9 with his foot, and the adjusting member 9 at this time makes a circular motion in the vertical downward direction on the foot pedal 1, and the adjusting member 9 at this time will force the movable caliper 3 to move in the direction close to the fixed caliper 6 through the transmission mechanism, and then adjust the relative position of the fixed caliper 6 and the movable caliper 3. The position enables a user who steps on the foot pedal 1 to climb on the column; because the adjusting member 9 always applies a traction force to the movable caliper 3 through the transmission mechanism, thereby preventing the movable caliper 3 from moving relative to the fixed caliper 6 from the foot pedal 1; and the force of the user stepping on the pedal is used to drive and limit the movable caliper 3, and the normal operation of the device can be guaranteed without the user having to exert additional physical strength and energy; and the above structure can also make the device adapt to columns of different diameters, thereby improving the scope of application of the device.

[0026] In some technical solutions of the utility model, a mounting base 11 is provided on the side wall of the pedal 1 , a sliding sleeve 2 is provided on the mounting base 11 , and a vertical section of the movable caliper 3 is slidably disposed in the sliding sleeve 2 .

[0027] In some technical solutions of the present utility model, the cross section of the sliding sleeve 2 and the cross section of the vertical section of the movable caliper 3 are both rectangular.

[0028] The mounting base 11 is an L-shaped plate, which is pressed together by a hydraulic press, and the mounting base 11 is fixed to the bottom of the foot pedal 1 by bolts or welding; the sleeve 2 is a steel sleeve with a rectangular cross section; the sleeve 2 is fixed to a side wall of the mounting base 11 by welding, so that the mounting base 11 and the sleeve 2 are combined into a "U" shape; and the movable caliper 3 includes a vertical section and an arc section, and the arc section and the vertical section are integrally formed, and the cross section of the vertical section is a rectangle, which can cooperate with the sleeve 2 to lock the movable caliper 3, thereby preventing the movable caliper 3 from making a circular motion in the sleeve 2 and affecting the safety of the device when in use.

[0029] In some technical solutions of the utility model, a movable claw 4 is rotatably provided on the inner side wall of the bent end of the movable caliper 3. The movable claw 4 can increase the contact area between the arc section of the movable caliper 3 and the outer wall of the column, that is, increase the friction surface between the arc section and the outer wall of the column, thereby improving the safety of the structure when in use.

[0030] In some technical solutions of the utility model, wear-resistant parts 5 are installed on the engaging surfaces of the movable claw 4 and the fixed caliper 6. The wear-resistant parts 5 are wear-resistant rubber, which are fixed on the engaging surfaces of the movable claw 4 or the fixed caliper 6 by screws to increase the friction when the outer wall of the structural column contacts.

[0031] In some technical solutions of the utility model, a binding member 17 for fixing the foot surface is installed on the top of the footrest 1. The binding member 17 is a strap, which is a wide band of nylon material; a plurality of buckles 18 are provided on the top of the footrest 1, and the buckles 18 are located on both sides of the footrest 1, and the binding member 17 is fixed to the footrest 1; when the operator's foot steps on the footrest 1, the binding member 17 alternately passes through the buckles 18 located on both sides of the footrest 1, and then is fixed on one of the buckles 18, so that the user's foot can be fixed on the footrest 1.

[0032] Example 2

[0033] Based on the embodiment 1 of the present utility model, according to Figure 2As shown, the specific structure of the transmission mechanism is that the transmission rod 8 is slidably arranged in the U-shaped area formed by the mounting base 11 and the sliding sleeve 2 through the mounting sleeve 7, and the axial direction of the transmission rod 8 is parallel to the axial direction of the vertical section of the movable caliper 3; the adjusting member 9 is rotatably arranged on the mounting base 11 through the pin shaft; the side wall of the adjusting member 9 is rotatably provided with a connecting rod 10 hinged to the transmission rod 8; the side wall of the transmission rod 8 is hinged with a linkage rod 12, and the free end of the linkage rod 12 passes through the notch provided on the outer wall of the sliding sleeve 2 and is hinged to the vertical section of the movable caliper 3; the middle part of the linkage rod 12 is hinged to the mounting base 11. In addition, a first tension spring connected to the adjusting member 9 is arranged in the mounting base 11, and the first tension spring can provide tension for the adjusting member 9. When the adjusting member 9 is not subjected to the downward pressure of the foot, the adjusting member 9 is in the initial state, and the distance between the movable caliper 3 and the fixed caliper 6 is the largest at this time; it is convenient for the device to adapt to columns of different sizes.

[0034] Example 3

[0035] Based on the embodiment 1 of the present utility model, according to Figure 3 As shown, the specific structure of the transmission mechanism is as follows: the transmission mechanism includes a first rack 13 slidably arranged on the mounting base 11 through a slide groove 20 and a slide bar 14, and a pull rod hinged to the first rack 13 is rotatably arranged on the side wall of the adjusting member 9; a guide groove is provided on the outer wall of the sliding sleeve 2 along its axial direction, and a second rack 16 connected to the vertical section of the movable caliper 3 is arranged in the guide groove, and a gear 15 meshing with the first rack 13 and the second rack 16 is rotatably arranged on the side wall of the mounting base 11. In addition, a second tension spring connected to the adjusting member 9 is arranged in the mounting base 11, and the tension spring can provide tension for the adjusting member 9. When the adjusting member 9 is not subjected to the downward pressure of the foot, the adjusting member 9 is in the initial state, and the distance between the movable caliper 3 and the fixed caliper 6 is the largest; it is convenient for the device to adapt to columns of different sizes.

[0036] Furthermore, the first rack 13 and the second rack 16 are driven by the meshing relationship of the gear 15, which can provide a certain locking capability for the above-mentioned motion mechanism.

[0037] Furthermore, some parts of the two transmission mechanisms can be commonly used.

[0038] In summary, the movement process of this structure is: when the staff lifts his foot, the gravity applied to the adjusting member 9 disappears, and the movable caliper 3 moves away from the fixed caliper 6, and the two will no longer be clamped on the pole; the staff lifts his foot, and the movable caliper 3 and the fixed caliper 6 rise together with the staff's foot, and then continue to apply downward pressure to the adjusting member 9, and the movable caliper 3 and the fixed caliper 6 will be clamped on the pole again, and this cycle will be repeated, thereby helping the staff to climb the pole.

[0039] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
