Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ladders for replacing insulators, in particular to a ladder for replacing insulators under power. Background Art
[0002] Currently, synthetic insulators are widely used in heavily polluted areas on power transmission lines. When these insulators age or overheat, they need to be replaced. Because the sheds of synthetic insulators are made of silicone and cannot be stepped on, workers need to climb up to a higher location using a ladder to replace them.
[0003] The existing ladder for replacing insulators has poor stability. Usually, two straight ladders are simply unfolded and stood on the ground, with only the bottom of the ladder in contact with the ground. As a result, the entire ladder shakes violently and obviously when the workers climb up the ladder. In addition, the ladder is high. Once the workers standing at a high place are blown by the wind and feel the ladder shaking, or even being dragged away, it is extremely dangerous, which has a great impact on the replacement work of personnel and brings great inconvenience to the construction work. Utility Model Content

[0006] To achieve the above-mentioned purpose, the technical solution of the present invention is: a ladder for replacing insulators under power, comprising: a lower ladder, an upper ladder, a standing plate, a rotating shaft seat, a support rod, and an adjustment assembly, wherein the upper ladder is installed on the upper side of the lower ladder; the standing plate is connected to the upper ladder; the rotating shaft seat is installed on the side of the lower ladder; the support rod is connected to the rotating shaft seat; one side of the adjustment assembly is connected to the lower ladder and the other side is connected to the support rod; wherein the adjustment assembly comprises a first shaft rod, a connecting handle, a sliding groove, a clamping groove, and a second shaft rod, a sliding groove is provided on the connecting handle, the clamping groove is connected to the sliding groove, the first shaft rod is installed on the side of the lower ladder and penetrates into the sliding groove, and the second shaft rod is installed on the support rod and penetrates into the sliding groove.
[0007] Preferably, the width of the slot is greater than or equal to the diameter of the second shaft.
[0008] Preferably, a handrail is installed on the upper part of the ladder.
[0009] Preferably, a guardrail is connected to the handrail rod.
[0010] Preferably, a rack is installed transversely at the connection between the lower ladder and the upper ladder.

[0012] Preferably, a plurality of bumps are provided on the lower side of the anti-slip base plate.
[0013] Preferably, an elliptical hole is provided on the protrusion.
[0014] Preferably, anti-slip teeth are installed on both sides of the elliptical hole.
[0015] By adopting the above technical solution, the beneficial effect of the utility model is as follows: the utility model pulls the support rod outward, and the support rod rotates outward under the action of the rotating shaft seat, and the second shaft rod slides along the direction of the sliding groove. When the support rod rotates out to a distance that contacts the ground, the second shaft rod moves into the corresponding card slot, and the support rod is fixed in the resting position.

DETAILED DESCRIPTION
[0026] The following describes the implementation of the present invention in detail with reference to the accompanying drawings and examples, so that the implementation process of how the present invention applies technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly. It should be noted that as long as no conflict arises, the various embodiments of the present invention and the various features in each embodiment can be combined with each other, and the resulting technical solutions are all within the scope of protection of the present invention.
[0027] Meanwhile, in the following description, many specific details are set forth for the purpose of explanation to provide a thorough understanding of the embodiments of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the specific details or the specific manner described herein.
[0028] See also Figure 1-3The utility model provides a climbing ladder for replacing insulators under power, comprising: a lower ladder 1, an upper ladder 2, a standing plate 3, a rotating shaft seat 4, a support rod 5, and an adjusting assembly 6. The upper ladder 2 is installed on the upper side of the lower ladder 1; the standing plate 3 is connected to the upper ladder 2; the rotating shaft seat 4 is installed on the side of the lower ladder 1; the support rod 5 is connected to the rotating shaft seat 4; one side of the adjusting assembly 6 is connected to the lower ladder 1, and the other side is connected to the support rod 5; wherein the adjusting assembly 6 includes a first shaft rod 61, a connecting handle 62, a sliding groove 63, a clamping groove 64, and a second shaft rod 65. A sliding groove 63 is opened on the connecting handle 62, and the clamping groove 64 is connected to the sliding groove 63. The first shaft rod 61 is installed on the side of the lower ladder 1 and penetrates into the sliding groove 63. The second shaft rod 65 is installed on the support rod 5 and penetrates into the sliding groove 63.
[0029] When the ladder is in use, the lower ladder 1 and the upper ladder 2 are unfolded and placed on the ground. The support rod 5 is then pulled outward and rotated outward under the action of the rotating shaft seat 4. The second shaft rod 65 slides along the direction of the sliding groove 63. When the support rod 5 is rotated out to a distance that touches the ground, the second shaft rod 65 moves into the corresponding clamping groove 64 to fix the support rod 5 in the resting position. The synchronous triangular support of the support rod 5 and the lower ladder 1 has the effect of enhancing the stability of the ladder. When the ladder is folded and stored, the second shaft rod 65 is disengaged from the clamping groove 64, and the support rod 5 is pushed toward the lower ladder 1. Under the action of the first shaft rod 61, the connecting handle 62 and the support rod 5 can be folded back to the lower ladder 1, which is convenient for transportation after storage and reduces the space occupied.
[0030] According to some embodiments of the present application, optionally, the width of the slot 64 is greater than or equal to the diameter of the second shaft 65 , so as to enable the second shaft 65 to smoothly enter the slot 64 .
[0031] According to some embodiments of the present application, optionally, a handrail 7 is installed on the upper part of the upper ladder 2. It has the function of being used for staff to hold on to, making it more convenient and safe to climb up the ladder.
[0032] According to some embodiments of the present application, optionally, a fence rod 8 is connected to the handrail 7. It has the effect of blocking the staff on the standing board 3, so that the replacement operation is safer.
[0033] According to some embodiments of the present application, optionally, a frame rod 9 is installed transversely at the connection between the lower ladder 1 and the upper ladder 2. It has the function of propping the lower ladder 1 and the upper ladder 2 apart.
[0034] According to some embodiments of the present application, the bottom of the step ladder 1 is optionally installed with an anti-skid base plate 10, and a plurality of protrusions 11 are provided on the lower side of the anti-skid base plate 10, and an elliptical hole 12 is opened on the protrusion 11, and anti-skid teeth 13 are installed on both sides of the elliptical hole 12. The bottom of the step ladder 1 of the prior art usually only has a rubber sleeve for anti-skid, but the weight of the worker's own body plus the tools and accessories such as insulators he carries is heavy, and the step ladder 1 may still slide and deflect. Therefore, the present application adds protrusions 11 under the anti-skid base plate 10, and the protrusions have the function of increasing friction with the ground, and anti-skid teeth 13 are provided under the protrusions 11. The anti-skid teeth 13 are in contact with the ground and can be stuck in the ground, thereby enhancing the anti-skid degree of the step ladder 1, making it less likely to deflect and slide, and making ladder climbing safer.
