Technical Field

[0001] The invention relates to the field of electric power engineering, in particular to a high-altitude working device for repairing electric poles. Background Art

[0002] When inspecting and repairing electricity, workers are required to climb up along the poles to a high place to carry out their work. When workers are working on the poles, the workers and the poles are only connected by foot buckles, and the foot buckles are arc-shaped. The foot buckles and the poles only rely on the weight of the workers to generate a large friction between the foot buckles and the poles, so that the workers can stand on the poles. When the workers shake, the foot buckles may detach from the poles, which leads to greater risks in the maintenance process of the workers.

[0003] Therefore, it is necessary to design an aerial work device for electric pole maintenance, which is fixed on the top of the electric pole and used to hang the safety belt of the operator, so as to increase the operating safety of the operator. Summary of the invention

[0014] Through the above technical solution, the arrangement of the arc strip effectively increases the strength of the middle part of the moving rod, thereby improving the bending strength of the moving rod.

[0015] Preferably, a limiting bolt capable of abutting against the arc strip is threadedly connected to the sliding block.

The locking rod 40 is provided with a plurality of locking grooves 401 equidistantly distributed along the locking rod 40. The locking rod 40 passes through the fixing plate 11 on the other fixing frame 10. The fixing plate 11 on the other fixing frame 10 is fixed with two pin seats 43, which slide inwardly. A locking pin 44 is movably connected, and the locking pin 44 abuts against the bottom wall of the locking groove 401, so that the locking rod 40 can only slide in the direction in which the two fixed frames 10 approach each other. A through cavity 102 is opened on the peripheral wall of the fixed frame 10, and two ears 12 located on both sides of the through cavity 102 are fixed on one of the fixed frames 10.

One end of the fastening bolt 25 expands radially outward and abuts against the clamping plate 21 on one side. The other end of the fastening bolt 25 is threadedly connected with a fastening nut 26, and the fastening nut 26 abuts against the clamping plate 21 on the other side. A wheel groove 201 is provided in the moving rod 20 and passes through the fixing frame 10 radially. The supporting wheel 22 is rotatably connected in the wheel groove 201. A slider 31 fixed in the wheel groove 201 is provided between adjacent supporting wheels 22. An arc bar 30 is slidably connected in the slider 31. The arc bar 30 passes through the moving rod 20. Both ends of the arc bar 30 are fixed on the fixing frame 10. A limiting bolt 32 that can abut against the arc bar 30 is threadedly connected on the slider 31.

[0029] Reference Figure 1 , Figure 2 , Figure 4 The two fixing plates 11 on one fixing frame 10 are each provided with two vertically symmetrical mounting grooves 113, and the locking rod 40 is rotatably connected to the mounting groove 113. The two fixing plates 11 on the other fixing frame 10 are each provided with two vertically symmetrical sliding grooves 112. The lower side wall of the lowermost sliding groove 112 is provided with a limiting groove 111 that penetrates the fixing plate 11 upward. The limiting rod 41 is embedded in the limiting groove 111. The locking rod 40 is located between the limiting rod 41 and the side wall of the sliding groove 112. The pin The seat 43 is fixed on the fixed plate 11, the locking groove 401 is composed of a guide surface 4011 and a locking surface 4012, a spring cavity 45 is opened in the pin seat 43, the locking pin 44 is slidably connected in the spring cavity 45, a spring 46 is fixed between the locking pin 44 and the bottom wall of the spring cavity 45, the locking surface 4012 is parallel to the sliding direction of the locking pin 44, the guide surface 4011 is perpendicular to the sliding direction of the locking pin 44, and a convex plate 42 is fixed to the upper end of the limit rod 41, and the convex plate 42 abuts against the upper end surface of the fixed plate 11.

[0030] When the present invention is in use, the operator first hangs the safety belt on the two hanging ears 12, and then aligns the two frames so that the locking rod 40 is aligned with the interval between the limit rod 41 and the side wall of the slide groove 112, and presses the two frames toward each other until the support wheel 22 is close to the outer periphery of the pole.

[0031] At this time, push the moving rod 20 to slide along the arc strip 30, so as to adjust the relative positions of the four moving rods 20, so that the four moving rods 20 are evenly distributed along the circumference of the pole, and then tighten the limiting bolt 32 so that the limiting bolt 32 is tightly abutted against the arc strip 30, so as to limit the moving rod 20.

[0032] Afterwards, the operator climbs up the pole using the foot buckles and pushes the frame upward with both hands. Since the diameter of the pole gradually decreases from bottom to top, the operator presses the frame toward the pole with both hands during the upward climbing process, so that the support wheel 22 is always in contact with the outer periphery of the pole.

[0033] When the operator climbs up to the highest point to perform maintenance work, the support wheels 22 on the two frames abut against the outer periphery of the utility pole, and the locking pin 44 can limit the locking rod 40, so that the frame cannot move away from the utility pole, thereby ensuring the stability of the connection between the frame and the utility pole, and further ensuring the maintenance safety of the operator.

All of these modifications fall within the scope of protection of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
