Technical Field

[0001] The utility model relates to the technical field of ladders, in particular to a ladder anti-side slip device. Background Art

[0002] A ladder is a tool used to climb or descend, usually consisting of some horizontal and vertical bars. Ladders can be used to work inside or outside buildings, and can also be used to reach or repair items. Common types of ladders include straight ladders, folding ladders, scaffolding ladders, etc. When using a ladder, you need to pay attention to safety and ensure that the ladder is stable and used correctly.

[0003] The existing related technologies often have the following defects: in the process of repairing outdoor power distribution lines, ladders are needed. The ladders are prone to slipping during use, and human or mechanical assistance is required to carry out inspection and repair of the ladders, which slows down the repair progress and greatly increases the cost. There are safety hazards in the human or mechanical assistance process of the ladders.

[0029] Reference Figure 1 As shown, the utility model provides a technical solution: a ladder anti-skid device, comprising a first ladder frame 1, the side wall of the first ladder frame 1 is rotatably connected to a second ladder frame 2, the surface of the first ladder frame 1 is provided with an anti-skid structure 3, and the surface of a rectangular plate 37 is provided with a control structure 4.

[0030] The specific configuration and function of the anti-skid structure 3 and the control structure 4 will be described in detail below.

[0031] Reference Figure 1-Figure 2 and Figure 4-Figure 5As shown, in this embodiment: the anti-skid structure 3 includes a first limit frame 31 fixedly connected to the first ladder frame 1, a guide rail 34 is fixedly connected to the surface of the first ladder frame 1, a slide plate 35 is slidably connected to the side wall of the guide rail 34, and a second limit frame 32 is fixedly connected to the side wall of the slide plate 35. The surfaces of the first limit frame 31 and the second limit frame 32 are both provided with a "V"-shaped notch, a rectangular plate 37 is slidably connected to the inside of the slide plate 35, and a clamping block 36 is fixedly connected to the end face of the rectangular plate 37. The side wall of the guide rail 34 is evenly provided with a plurality of clamping grooves 39. The clamping block 36 is inserted into the inner side of the corresponding clamping groove 39 on the guide rail 34, thereby achieving the fixing work of the first ladder frame 1. At this time, the second ladder frame 2 can be unfolded for use, avoiding the phenomenon of side sliding during the use of the ladder. The clamping block 36 is a straight triangular prism structure. The clamping block 36 of the straight triangular prism structure has an irreversible effect in the process of relative movement between the clamping groove 39 on the guide rail 34.

[0032] Two springs 38 are fixedly connected to the side where the block 36 and the slide plate 35 are close to each other. After the first limit frame 31 and the second limit frame 32 are sleeved on the side wall of the electric pole, the block 36 is inserted into the inner side of the corresponding slot 39 on the guide rail 34 under the elastic force of the spring 38. Two anti-skid pads 33 are fixedly connected to the inner side of the first limit frame 31 and the second limit frame 32. By providing the anti-skid pads 33, the friction force of the first limit frame 31 and the second limit frame 32 against the electric pole for use is increased.

[0033] Reference Figure 1-Figure 4 As shown, specifically, the control structure 4 includes a pull rope 41 fixedly connected to the surface of the rectangular plate 37, and a pull ball 44 is fixedly connected to the lower end of the pull rope 41. When the pull ball 44 is pulled, the pull ball 44 drives the pull rope 41 to twitch.

[0034] The surface of the slide plate 35 is fixedly connected to the support frame 42, and the pull rope 41 is slidably connected to the inside of the support frame 42. The pull rope 41 slides inside the support frame 42, which can reduce the occurrence of the pull rope 41 and the pulley 43 being easily misaligned during use. The inner side of the support frame 42 is rotatably connected to the pulley 43, and the pull rope 41 is located on the side wall of the pulley 43. The pull rope 41 slides on the surface of the pulley 43 to change the pulling direction of the pull rope 41.

[0035] Working principle: when the ladder needs to be used, first put the first limiting frame 31 and the second limiting frame 32 on the side wall of the pole, then slide the slide 35 on the guide rail 34, the slide 35 will drive the second limiting frame 32 to move toward the surface close to the pole, wherein the block 36 of the straight triangular prism structure has an irreversible effect in the process of relative movement with the card slot 39 on the guide rail 34, after the first limiting frame 31 and the second limiting frame 32 are put on the side wall of the pole, the block 36 will be inserted into the inner side of the corresponding card slot 39 on the guide rail 34 by the elastic force of the spring 38, thereby realizing the fixing of the first ladder frame 1, and the second ladder frame 31 and the second limiting frame 32 can be unfolded at this time. The use of two ladder frames 2 can avoid the side slip of the ladder during use. By setting the anti-skid pad 33, the friction between the first limit frame 31 and the second limit frame 32 against the electric pole is increased, and the stability of fixing the first ladder frame 1 is further improved. By setting the first limit frame 31 and the second limit frame 32 with "V"-shaped structural grooves, the fixing work of electric poles with different inner diameters is facilitated. By setting the anti-skid structure 3, the fixing work of the first ladder frame 1 on the ladder is facilitated, and the side slip of the ladder during use is avoided, which improves the safety and stability of the ladder during use to a certain extent.

[0036] By pulling the pull ball 44, the pull ball 44 will drive the pull rope 41 to be pulled, and the pull rope 41 slides on the surface of the pulley 43 to change the pulling direction of the pull rope 41. At this time, the pulling work of the rectangular plate 37 can be realized, which facilitates the work of pulling the block 36 out from the inner side of the card slot 39, thereby facilitating the disassembly of the first ladder frame 1 located on the surface of the pole after coming down from a high place. The pull rope 41 slides inside the support frame 42, which can reduce the occurrence of the pull rope 41 being easily misaligned with the pulley 43 during use. By setting the control structure 4, it is convenient to disassemble the first ladder frame 1 from the side wall of the pole at a low position, and further improves the disassembly efficiency of the first ladder frame 1 after the personnel come down from the ladder frame.
