In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0024] Please also read Figures 1 to 8 The ice-covered pole maintenance ladder provided by the present application is now described. The ice-covered pole maintenance ladder comprises a support rod 1, a plurality of pedals 3, a plurality of clamping plate groups, a plurality of adjustment components 5 and a plurality of tensioning components.

[0025] The support rod 1 is made of light metal or high-strength non-metal material, so that maintenance personnel can easily transfer the support rod 1.

[0026] Multiple pedals 3 are distributed at intervals along the axial direction of the support rod 1. They can be arranged alternately and staggered on both sides of the support rod 1, or two pedals 3 can be distributed in a group along the axial direction of the support rod 1; each pedal 3 has an anti-slip layer on the surface, which can improve the anti-slip performance of the pedal 3 and reduce the risk of maintenance personnel slipping when they step on the pedal 3.

[0027] Multiple groups of splint groups are distributed at intervals along the axial direction of the support rod 1, and the number of splint groups can be adjusted as needed. The attached figure only shows one of the settings of the ice covering maintenance ladder of the present application; each group of splint groups includes two splints 4 clamped on the pole 8, and one end of each splint 4 is hinged to the support rod 1.

[0028] Multiple groups of adjustment components 5 are connected to multiple groups of clamping plate groups in a one-to-one correspondence, and are used to adjust the degree of engagement of the two clamping plates 4. The adjustment components 5 can adopt a threaded adjustment mechanism or a ratchet adjustment mechanism, and the operation form can be electric adjustment or manual adjustment.

[0029] Multiple sets of tensioning components are connected to multiple sets of clamping plate groups in a one-to-one correspondence; the tensioning components are coated on the clamping surfaces of the two clamping plates 4 to fill the gap between the clamping plates 4 and the poles 8; the tensioning components can be inflatable components, water-filled components, or in the form of a top screw pushing an inclined plate.

[0030] In the embodiment of the present application, when it is necessary to inspect and repair the pole 8 with ice on the surface, the support rod 1 is set on the side of the pole 8, and the two clamps 4 in each group of clamps are clamped on the pole 8, and then the adjustment member 5 corresponding to each group of clamps is adjusted to adjust the degree of engagement of the two clamps 4, and finally the tensioning assembly corresponding to each group of clamps is controlled to fill the gap between the clamp 4 and the pole 8, thereby increasing the clamping force between the clamp 4 and the pole 8, thereby greatly improving the anti-slip performance of the maintenance ladder.

[0031] The ice-covered pole maintenance ladder provided in the embodiment of the present application has good anti-slip performance and is easy to use compared with the prior art, and can achieve safe climbing of the pole when the pole 8 is covered with ice.

[0032] In some embodiments, the tensioning assembly may be configured as follows: Figures 1 to 7 The structure shown, see Figures 1 to 7 The tensioning assembly includes an airbag 61, an inflatable member 7 and an isolation cloth 62.

[0033] The airbag 61 is arranged on the clamping surface of the clamping plate 4, and the clamping surface of the clamping plate 4 has an installation groove for the airbag 61 to be embedded; the number of the airbags 61 can be multiple, which are arranged in parallel on the clamping surface of the clamping plate 4, and the interiors of the multiple airbags 61 are connected.

[0034] The inflatable component 7 is arranged on the splint 4 or the support rod 1 and is connected to the airbag 61; the inflatable component 7 is used to introduce gas into the airbag 61 so that the airbag 61 expands after being subjected to the pressure of the internal gas; the inflatable component 7 can use an inflatable pump, and the outlet end of the inflatable pump is connected to the air inlet of the airbag 61.

[0035] The isolation cloth 62 is wrapped on the airbag 61 and is used to contact the outer peripheral surface of the pole 8; after the inflatable component 7 introduces gas into the airbag 61, the airbag 61 expands, which can simultaneously push the isolation cloth 62 wrapped on the outside of the airbag 61 to deform, so that the isolation cloth 62 is wrapped around the outer peripheral wall of the pole 8, and then fills the gap between the splint 4 and the pole 8; wherein, the isolation cloth 62 is made of a material with strong toughness and good wear resistance. The isolation cloth 62 can protect the airbag 61 from being worn during use, thereby increasing the service life of the airbag 61.

[0036] In some embodiments, the isolation cloth 62 may be made of Figure 1 , Figure 2 , Figure 3 and Figure 6 The structure shown, see Figure 1 , Figure 2 , Figure 3 and Figure 6 The contact surface of the isolation cloth 62 has a plurality of first anti-slip protrusions 621, which can be made of rubber material. Each first anti-slip protrusion 621 is ultrasonically welded on the isolation cloth 62 to prevent it from falling off during use. The first anti-slip protrusion 621 can adopt an elliptical structure, which is used to increase the contact area between the first anti-slip protrusion 621 and the pole 8 when the isolation cloth 62 is wrapped around the pole 8, thereby improving the anti-slip performance of the isolation cloth 62.

[0037] In some embodiments, the inflatable member 7 may be Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 The structure shown, see Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 The inflatable component 7 includes a compressed gas cylinder 71 and an air pipe 72.

[0038] The compressed gas cylinder 71 is set on the splint 4 or the support rod 1, and the compressed gas cylinder 71 can be fixed on the splint 4 or the support rod 1 by using a special mounting base; the compressed gas cylinder 71 can adopt a small disposable carbon dioxide cylinder, which can store compressed carbon dioxide inside. When the compressed gas cylinder 71 releases the internal carbon dioxide gas, since the external pressure is lower than the pressure inside the compressed gas cylinder 71, the carbon dioxide can quickly expand in volume when released from the compressed gas cylinder 71.

[0039] The air pipe 72 is arranged on the clamping plate 4 , the air inlet end is connected to the compressed air cylinder 71 through the control valve 73 , and the air outlet end is connected to the air bag 61 .

[0040] When the two clamps 4 in the clamp group are clamped on the electric pole 8, the compressed gas inside the compressed gas cylinder 71 can be quickly released by opening the control valve 73. Since the pressure inside the airbag 61 is lower than the pressure inside the compressed gas cylinder 71, the compressed gas inside the compressed gas cylinder 71 can expand rapidly, thereby filling the inside of the airbag 61, and the pressure of the compressed gas can cause the airbag 61 to expand. The above process is easy to operate, saves time and effort, and the compressed gas cylinder 71 can be refilled after use, which reduces the cost of each use and improves the practicality of the equipment.

[0041] In some embodiments, the splint set can be used as follows Figure 1 , Figure 2 , Figure 3 and Figure 5 The structure shown, see Figure 1 , Figure 2 , Figure 3 and Figure 5 The splint assembly further includes a first gear 41 and a second gear 42 .

[0042] The first gear 41 is arranged on a hinge shaft of one of the clamping plates 4 .

[0043] The second gear 42 is disposed on a hinge shaft on the other clamping plate 4 and meshes with the first gear 41 .

[0044] The first gear 41 and the second gear 42 are meshed with each other to achieve synchronous rotation of the two clamps 4. When the two clamps 4 need to be clamped on the pole 8, it is only necessary to control one of the clamps 4 to rotate toward the pole 8 to achieve synchronous rotation of the two clamps 4. The above technical solution reduces the operating steps of maintenance personnel, saving time and effort.

[0045] In some embodiments, the splint set can be used as follows Figures 1 to 5 The structure shown, see Figures 1 to 5 The splint assembly also includes a fixing seat 2.

[0046] The fixing seat 2 is sleeved and fixed on the support rod 1; one end of the two clamps 4 is respectively hinged to the fixing seat 2; a detachable connection method can also be adopted between the fixing seat 2 and the support rod 1, so that the installation position of the fixing seat 2 can be adjusted according to needs; the number of fixing seats 2 can also be increased or decreased according to needs. When the length of the support rod 1 is longer, it is suitable to increase the number of fixing seats 2, and when the length of the support rod 1 is shorter, it is suitable to reduce the number of fixing seats 2.

[0047] In some embodiments, the adjusting member 5 may be configured as follows: Figures 1 to 5 The structure shown, see Figures 1 to 5 The adjusting component 5 includes a fixing sleeve 51 , a screw rod 52 and an adjusting nut 53 .

[0048] The fixing sleeve 51 is rotatably disposed on the fixing seat 2 along the axial direction of the supporting rod 1 ; the axial direction of the fixing sleeve 51 is perpendicular to the axial direction of the supporting rod 1 .

[0049] The screw 52 is inserted into the fixed sleeve 51, and one end is hinged to one of the clamps 4. The hinge axis of the screw 52 is parallel to the axis of the support rod 1. When the screw 52 moves along the axial direction of the fixed sleeve 51, it can synchronously drive the clamp 4 to swing. The maintenance personnel can adjust the swing position of the clamp 4 by controlling the axial movement distance of the screw 52 along the fixed sleeve 51.

[0050] The adjusting nut 53 is connected to the other end of the screw rod 52 and abuts against the sliding seat, and is used to adjust the distance that the screw rod 52 extends out of the fixing sleeve 51; the maintenance personnel can adjust the distance that the screw rod 52 extends out of the fixing sleeve 51 by turning the adjusting nut 53, and then adjust the swing position of the splint 4; by adopting the above technical solution, when adjusting the swing position of the splint 4, the operation is simple, time-saving and labor-saving.

[0051] In some embodiments, the fixing base 2 may be Figure 1 , Figure 2 , Figure 3 and Figure 5 The structure shown, see Figure 1 , Figure 2 , Figure 3 and Figure 5 The fixing seat 2 has an arc groove 21 in which the power supply pole 8 is partially embedded; the arc groove 21 has a plurality of second anti-skid protrusions 22; when the ice-covered maintenance ladder needs to be installed on the pole 8, the arc groove 21 can be firstly abutted against the outer peripheral wall of the pole 8 to achieve the purpose of pre-positioning the maintenance ladder, and the second anti-skid protrusions 22 can increase the friction between the arc groove 21 and the pole 8.

[0052] The second anti-skid protrusion 22 can be made of rubber material, and the second anti-skid protrusion 22 can adopt an elliptical structure to increase the contact area between the second anti-skid protrusion 22 and the pole 8, thereby improving the anti-skid performance between the fixing seat 2 and the pole 8.

[0053] In some embodiments, the pedal 3 may be Figures 1 to 4 The structure shown, see Figures 1 to 4 The pedals 3 are divided into two rows and are respectively arranged on both sides of the support rod 1; wherein, each row of pedals 3 is connected by a connecting rod 31; the connecting rod 31 is used to make multiple pedals 3 in the same row swing synchronously.

[0054] After the support rod 1 is installed on the electric pole 8, the maintenance personnel can pull the connecting rod 31 to make the multiple pedals 3 swing synchronously to a horizontal state. This process saves time and effort. Moreover, when the maintenance personnel are climbing the pole, the connecting rod 31 can provide a handhold. The maintenance personnel can improve their own stability by holding the connecting rod 31, thereby improving the safety during the climbing process.

[0055] In some embodiments, the support rod 1 may be Figure 3 and Figure 4 The structure shown, see Figure 3 and Figure 4 There are multiple support rods 1, which are arranged in parallel along the axial direction of the pole 8; wherein each support rod 1 includes a plug 11 and a slot 12.

[0056] The plug 11 is arranged at the upper end of the support rod 1 , and the slot 12 is arranged at the lower end of the support rod 1 ; when multiple support rods 1 are arranged in parallel along the axial direction of the pole 8 , the plug 11 on one support rod 1 is plugged into the slot 12 on the adjacent support rod 1 .

[0057] When the height of the electric pole 8 is relatively high, the height of the maintenance ladder can be increased by increasing the number of support poles 1, and the increased support poles 1 are also provided with pedals 3, a splint group, an adjustment member 5 and a tensioning member; the two upper and lower adjacent support poles 1 can be matched with each other through a plug 11 and a slot 12, thereby improving the connection strength between the two adjacent support poles 1.

[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
