[0002] A cable is a conductor used to transmit power or signals, usually composed of multiple strands of wire or a conductor wrapped in insulating material. It is generally composed of a core, an insulating layer, a sheath, a filler, a shielding layer, etc. There are many types and the fields involved are also relatively wide. When connecting cables, it generally includes preparation work, measurement and stripping, installation of insulation, grounding preparation, fixing, inspection and testing, etc. In the step of installing insulation, some cables use one-piece rubber insulation. Because the insulation sealing effect needs to be maintained, the rubber insulation and the cable are interference fit when they are sleeved. Therefore, when sleeved, a lot of force is required to complete the installation of the insulation.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Embodiment 1:

[0027] like Figure 1-Figure 8 As shown, an auxiliary device for high-voltage cable connection includes a mounting frame, wherein a group of clamping components are respectively arranged at both ends of the mounting frame for clamping the cable 201, and a group of wire-retracting components are respectively arranged at both ends of the mounting frame, and the two ends of the steel cable 105 are respectively connected to the two groups of wire-retracting components; it also includes a pushing plate, and the steel cable 105 passes through the pushing plate. Through the coordinated operation of the two groups of wire-retracting components, the steel cable 105 pulls the pushing plate, thereby realizing that the pushing plate pushes the rubber insulating sleeve 204.

[0028] When one set of take-up components is releasing the wire and the other set of take-up components is taking up the wire, the steel cable 105 will drive the push plate to move, and the push plate will push the rubber insulating sleeve 204 to slide on the insulating layer 202 or the voltage equalizing sleeve 203, so that the rubber insulating sleeve 204 partially covers the two insulating layers 202 and completely covers the voltage equalizing sleeve 203. Through the above arrangement, the labor intensity of personnel can be reduced, and the connection efficiency and connection quality can be improved.

[0029] Embodiment 2:

[0030] This embodiment is further optimized on the basis of embodiment 1. Figure 5 , Figure 6As shown, the push plate includes a first push plate unit 112 and a second push plate unit 113, which are fixed together by bolts 114, and the first push plate unit 112 and the second push plate unit 113 are provided with holes for the supply steel cable 105 to pass through; both sides of the first push plate unit 112 and the second push plate unit 113 are set to fit the shape of the end of the rubber insulating sleeve 204.

[0031] The first unit 112 and the second unit 113 of the push plate are freely hung on the steel cable 105. When it is necessary to operate, the staff will use two wire-retracting assemblies to loosen the steel cable 105, and then plug the first unit 112 and the second unit 113 of the push plate together, and then use multiple bolts 114 to completely fix the first unit 112 and the second unit 113 of the push plate together to form a push plate, and then put the push plate on the rubber insulating sleeve 204, drive the two wire-retracting assemblies, so that the push plate pushes the rubber insulating sleeve 204 to move. Through the above arrangement, the overall rigidity of the push plate can be improved to prevent the push plate from being deformed during the operation.

[0032] like Figure 5 , Figure 6 As shown, there are two steel cables 105, one of which passes through the first unit 112 of the pushing plate, and the other passes through the second unit 113 of the pushing plate. Two limiting plates 111 are fixedly connected to the steel cable 105, and the two limiting plates 111 are distributed on both sides of the pushing plate. The outer diameter of the limiting plate 111 is larger than the diameter of the hole on the first unit 112 of the pushing plate or the second unit 113 of the pushing plate through which the steel cable 105 passes.

[0033] Through the above arrangement, the pushing plate can be evenly stressed, so that the rubber insulating sleeve 204 can be evenly stressed, thereby preventing the rubber insulating sleeve 204 from abnormally deforming due to uneven stress during movement.

[0034] like Figure 2 , Figure 5As shown, the wire take-up assembly includes a wire wheel 116, which is rotatably connected to the mounting frame, and the end of the steel cable 105 is fixedly connected to the wire wheel 116. The wire take-up assembly includes a plurality of steel cable support frames 115, and the steel cable support frames 115 enable the steel cable 105 to only give the force for the horizontal movement of the push plate when the push plate pushes 304. In the process of the push plate pushing the rubber insulating sleeve 204, the steel cable 105 guiding the push plate to move is in a horizontal state, and the steel cable 105 is arranged in parallel with the rubber insulating sleeve 204, so the push plate only gives the force for the horizontal movement of the rubber insulating sleeve 204. Through the above arrangement, the rubber insulating sleeve 204 can be subjected to uniform force, preventing the rubber insulating sleeve 204 from abnormal deformation due to uneven force during movement, and also reducing the force applied to the push plate.

[0035] like Figure 7 , Figure 8 As shown, the line taking-up assembly includes a driving unit, which includes a lever box 118 fixedly connected to the mounting frame, the lever box 118 is rotatably connected to the wire wheel 116, one end of the wire wheel 116 close to the lever box 118 is slidably connected to a self-locking gear 121, the self-locking gear 121 is fixedly connected to a forward ratchet 122, the forward ratchet 122 is fixedly connected to a reverse ratchet 123, and the reverse ratchet 123 is movably connected to the lever box 118; the lever box 118 is rotatably connected to a lever 117, the lever 117 is slidably connected to a first limiting lever 120, the first limiting lever 120 is fixedly connected to a first locking spring 119, and the first locking spring 119 is fixedly connected to the lever 117; the lever box 118 is slidably connected to a second limiting lever 124, the second limiting lever 124 is fixedly connected to a second locking spring 125, and the second locking spring 125 is fixedly connected to the lever box 118.

[0036] The first limiting rod 120 cooperates with the self-locking gear 121, the forward ratchet 122, and the reverse ratchet 123 respectively, and the second limiting rod 124 cooperates with the self-locking gear 121, the forward ratchet 122, and the reverse ratchet 123 respectively; when the first limiting rod 120 and the second limiting rod 124 are simultaneously engaged with the forward ratchet 122 or the reverse ratchet 123, the operator toggles the lever 117, and due to the action of the first locking spring 119 and the second locking spring 125, the wire wheel 116 will only rotate in one direction at this time, thereby completing the retracting or releasing operation of the steel cable 105; when the first limiting rod 117 is engaged with the forward ratchet 122 or the reverse ratchet 123, the operator toggles the lever 117, and due to the action of the first locking spring 119 and the second locking spring 125, the wire wheel 116 will only rotate in one direction, thereby completing the retracting or releasing operation of the steel cable 105; 20. When the second limit rod 124 engages with the self-locking gear 121 at the same time, since the first limit rod 120 and the second limit rod 124 simultaneously jam the self-locking gear 121, the operator cannot move the lever 117, and the self-locking gear 121 will also be limited by the first limit rod 120 and the second limit rod 124, so that the wire wheel 116 cannot rotate, and the steel cable 105 cannot move at this time; the first limit rod 120, the second limit rod 124 and the self-locking gear 121, the forward ratchet 122, and the reverse ratchet 123 are manually pulled by the operator to achieve the coordination state.

[0037] Through the above arrangement, when a person turns the lever 117, the wire wheel 116 can complete the retracting or releasing rotation; or the wire wheel 116 enters a self-locking state to prevent the steel cable 105 from scattering, thereby improving practicality.

[0038] like Figure 3 , Figure 4 As shown, the mounting frame includes a first mounting frame unit 101 and a second mounting frame unit 102. The first mounting frame unit 101 is slidably connected to the second mounting frame unit 102. The second mounting frame unit 102 is fixedly connected to a lead screw 103. The first mounting frame unit 101 is rotatably connected to a first turn buckle 104. The lead screw 103 is threadedly connected to the first turn buckle 104. A plurality of rollers 106 are provided on the mounting frame.

[0039] According to construction requirements, the first rotary buckle 104 is manually rotated to adjust the distance between the first unit 101 of the mounting frame and the second unit 102 of the mounting frame, thereby adjusting the length of the entire mounting frame. Through the above arrangement, cables with various connection lengths can be operated, thereby improving the scope of application.

[0040] like Figure 4 As shown, the clamping assembly includes a clamping seat 107, which is arranged on a mounting frame, and a plurality of clamping units 109 are slidably connected to the clamping seat 107, and a clamping spring 110 is fixedly connected to the clamping unit 109, and the clamping spring 110 is fixedly connected to the clamping seat 107, and a rubber sheet is arranged on the clamping unit 109.

[0041] The clamping unit 109 is pulled manually to overcome the elastic force of the clamping spring 110, and then the cable 201 is placed on the clamping seat 107. The person releases the clamping unit 109, and the clamping unit 109 clamps the cable 201 under the elastic force of the clamping spring 110, thereby limiting the position of the cable 201. Through the above arrangement, the cable 201 can be quickly supported and clamped to prevent the cable 201 from moving abnormally during the operation.

[0042] Embodiment 3:

[0043] This embodiment is further optimized on the basis of embodiment 2. Figure 4 As shown, the clamping seat 107 is slidably connected to the mounting frame, the mounting frame is rotatably connected to a second rotary buckle 108, and the second rotary buckle 108 is threadedly connected to the clamping seat 107.

[0044] By turning the second knob 108, the clamping seat 107 can lift the cable 201, that is, when the person only turns the second knob 108 on one side and does not turn the second knob 108 on the other side, the two cables 201 will be staggered with each other, resulting in a longitudinal spacing; for example: when the rubber insulating sleeve 204 needs to be installed on the right insulating layer 202, but the two cables 201 cannot move laterally due to environmental restrictions, the rubber insulating sleeve 204 cannot be put on the right insulating layer 202 due to the space occupied by the left cable 201. At this time, if the person makes the left clamping seat 107 lift the cable 201, the rubber insulating sleeve 204 can be smoothly put on the right insulating layer 202 through the push plate. Through the above settings, operations can be performed in a variety of scenarios, which improves the scope of application.

[0045] Working principle: After the staff brings the device to the work site, they adjust the length of the mounting frame according to the work requirements, then place the cable 201 on the clamping assembly, use the clamping assembly to limit the cable 201, and then perform preparatory work according to the work requirements, such as trimming the insulating layer 202, etc., and then adjust the length of the mounting frame or lift the clamping seat 107 on one side to make room for the rubber insulating sleeve 204 on the cable 201 on this side, and then put the pushing plate on the rubber insulating sleeve 204, and one end of the rubber insulating sleeve 204 is put on the end of the unmoved insulating layer 202, and then the personnel adjust the position of the two reverse ratchets 123 so that the pay-off assembly at the cable 201 on the side of the concession is in the pay-off state, while the other side is in the reeling state, and the personnel begin to turn the lever 117 in the reeling state, and at this time the steel cable 105 begins to drive the push plate The movable plate puts the rubber insulating sleeve 204 on the corresponding insulating layer 202, and then resets the cable 201 that has given way, so that the wire cores of the two cables 201 are in contact, and then the wire cores of the two cables 201 are crimped through the connecting tube, and then the voltage-equalizing sleeve 203 is installed at the connecting tube, and then the states of the two winding components are reversed. At this time, the personnel still toggle the lever 117 in the winding state. At this time, the steel cable 105 starts to drive the pushing plate to put the rubber insulating sleeve 204 on the voltage-equalizing sleeve 203, and then on the insulating layer 202 on the other side, so that the rubber insulating sleeve 204 partially covers the two insulating layers 202 and completely covers the voltage-equalizing sleeve 203, so that the rubber insulating sleeve 204 performs preliminary insulation and sealing on the wire core connection, and the auxiliary installation of the rubber insulating sleeve 204 is completed. After that, the subsequent steps are gradually completed to complete the connection of the cable 201.

[0046] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
