[0001] The utility model relates to the technical field of railway power line emergency repair, and particularly to a wire reset device for emergency repair of broken poles of power lines. Background Art

[0002] The railway industry requires a large number of power equipment. Currently, the commonly used power supply method is single-through power supply. Once a fault occurs in the power line, it will seriously affect the operation of station train operation equipment. When repairing a fault in the railway power line, the principle of "first make it through and then restore it" is adhered to in order to reduce the impact on the operation of station train operation equipment.

[0003] The railway industry generally uses 10KV power lines for power transmission. At present, when a broken pole fault occurs in a 10KV power line, emergency repair operations are carried out by operating personnel cooperating with large mechanical equipment. However, most of the 10KV power line equipment is in mountainous areas, hilly areas, cultivated land and other terrain complex sections. Affected by bad weather and complex terrain, many large pieces of equipment are difficult to reach the fault location, thus delaying the emergency repair operation time limit of the 10KV power line.

[0004] The existing emergency repair devices, such as the Chinese invention patent with the publication number of CN115182637A, discloses a rapid emergency repair device and method for a power transmission line, including a support frame. A lifting opening is provided on the right side of the top of the support frame. The front and rear parts of the top of the support frame are fixedly connected with first chute plates. A sliding plate is slidably installed inside the first chute plates. The top of the sliding plate is fixedly connected with a load-bearing plate through a fixing block. Although it can facilitate the removal of the broken pole and the lifting of the new pole to improve the efficiency of replacing the broken electric pole during the emergency repair process, it cannot achieve timely power-on and cannot meet the emergency repair requirements of the "first make it through and then restore it" for the railway power line.

[0005] Therefore, it is necessary to study a wire reset device for emergency repair of broken poles of power lines to solve the above problems or alleviate the impacts brought by the above problems. Summary of the Utility Model

Detailed implementation mode

[0030] The present utility model will be further described below in conjunction with the accompanying drawings.

[0031] As Figures 1 to 6 shown, the wire reset device for power line broken pole emergency repair of the present utility model may include a mobile support mechanism 3, a lifting mechanism 2, and a wire reset mechanism 1 that are connected in sequence from bottom to top;

[0032] Among them, the mobile support mechanism 3 is used for moving and transporting or supporting and fixing the lifting mechanism 2, the lifting mechanism 2 is used for lifting and adjusting the wire reset mechanism 1, and the wire reset mechanism 1 is used for fixedly supporting the wire.

[0033] Specifically, the mobile support mechanism 3 serves both as the mobile unit and the support and fixation unit of the wire reset device. When emergency repair operations are required, it can carry the lifting mechanism 2 and the wire reset mechanism 1 to the emergency repair location. After arriving at the emergency repair location, it can be fixed to the ground and can play a role in stably supporting the lifting mechanism 2 and the wire reset mechanism 1. The lifting mechanism 2 can lower the wire reset mechanism 1 to the lowest position when not in emergency repair for easy movement and transportation, and can adjust the wire reset mechanism 1 to the required height during emergency repair to replace electric poles of different heights. The wire reset mechanism 1 can fixedly support the wire and, under the adjustment of the lifting mechanism 2, support the wire at a safe height.

[0034] This enables the wire reset device to smoothly reach complex terrain sections for emergency repair operations, and can temporarily replace the electric pole to fixedly support the wire to a safe height, enabling power supply restoration to achieve the emergency repair principle of "first make it work and then restore it". Compared with the emergency repair method of operators cooperating with large-scale mechanical equipment, the wire reset device is both fast and convenient, and can also reduce the rental cost of large-scale machinery, reduce the emergency repair operation time, and greatly reduce the labor intensity of personnel.

[0035] In one example, as Figures 1 to 6As shown in the figure, the wire reset mechanism 1 includes a working platform 101 and a flipping support column 102. The flipping support column 102 can be retracted and extended on the working platform 101. When the flipping support column 102 is in the extended state, it is perpendicular to the working platform 101, and one end of the flipping support column 102 away from the working platform 101 can fixedly support the wire.

[0036] Specifically, the working platform 101 is connected to the top of the lifting mechanism 2 and serves as the direct object of the lifting adjustment of the lifting mechanism 2. The flipping support column 102 can be retracted and extended relative to the working platform 101. When there is no emergency repair, the flipping support column 102 is in the retracted state, and when there is an emergency repair, the flipping support column 102 is in the extended state. When the flipping support column 102 is in the extended state, its axial direction is the vertical direction and is perpendicular to the working platform 101. At this time, the lower end of the flipping support column 102 is fixed to the working platform 101, and its upper end can fixedly support the wire. In this way, the working platform 101 can facilitate the operation of the emergency repair personnel. The flipping support column 102 is extended and the wire is fixed to the upper end of the flipping support column 102, so that the wire reset device can temporarily replace the pole to fixedly support the wire.

[0037] Furthermore, as Figure 2 shown, an insulating cross arm 103 can be provided at the upper end of the flipping support column 102, and a pin insulator 104 is provided on the insulating cross arm 103 to facilitate the fixed installation of the wire, improve the insulation performance, and play an isolation and protection role. A pole top cap 105 can also be provided at the top of the flipping support column 102, and the pole top cap 105 plays roles such as protection, insulation, fixation, and support.

[0038] In one example, as Figure 5 and Figure 6 shown, a long slot 106 is provided on the working platform 101. One end of the flipping support column 102 is rotatably connected to one end of the long slot 106. The size of the flipping support column 102 matches the size of the long slot 106. When the flipping support column 102 is in the retracted state, it can be embedded in the long slot 106.

[0039] Specifically, a long slot 106 matching the flipping support column 102 is cut on the working platform 101, and the flipping support column 102 can be embedded in the long slot 106. One end of the flipping support column 102 is rotatably connected to one end of the long slot 106, and the flipping support column 102 can be flipped relative to the working platform 101. When there is no emergency repair, the flipping support column 102 is in the retracted state, that is, the flipping support column 102 is embedded in the long slot 106; when there is an emergency repair, the flipping support column 102 is flipped 90° relative to the working platform 101 and is in the extended state, that is, the flipping support column 102 is perpendicular to the working platform 101.

[0040] In one example, asFigure 1 and Figure 5 As shown in Figure 5 , a hydraulic lifting arm 107 is provided at the bottom of the working platform 101. The hydraulic lifting arm 107 passes through the long slot 106 and is connected to the flipping support column 102. The hydraulic lifting arm 107 can telescopically drive the flipping support column 102 to rotate relative to the working platform 101.

[0041] Specifically, one end of the hydraulic lifting arm 107 is hinged to the bottom of the working platform 101, and the other end is hinged to the body of the flipping support column 102. The telescopic movement of the hydraulic lifting arm 107 can flip the flipping support column 102 relative to the working platform 101, that is, the hydraulic lifting arm 107 provides power for the folding and unfolding of the flipping support column 102. It should be noted that there is a through hole at the bottom of the long slot 106 of the working platform 101, and the through hole provides an avoidance space for the telescopic adjustment of the hydraulic lifting arm 107.

[0042] In one example, as Figure 1 shown, the wire reset mechanism 1 further includes an insulating pad 108 and a platform guardrail 109. The insulating pad 108 is laid on the working platform 101, and the platform guardrail 109 surrounds the edge of the working platform 101.

[0043] Specifically, the insulating pad 108 can prevent the emergency repair personnel from getting an electric shock, and the insulating pad 108 should be able to meet the insulation strength requirements of 10KV. The platform guardrail 109 can prevent the emergency repair personnel from accidentally falling from the working platform 101. The platform guardrail 109 can be designed as a foldable type, which can be retracted when not in emergency repair and unfolded when in emergency repair.

[0044] Furthermore, as Figure 1 shown, a camera 110 can be provided on the side of the working platform 101. The function of the camera 110 is to facilitate shooting and recording the on-site operation situation during the emergency repair operation, which can enable the supervisors who have not arrived at the scene to master the on-site situation, so as to urge the emergency repair operation personnel to operate in a standardized manner and prevent illegal operations. The number and specific position of the camera 110 can be set according to the actual situation. For example, corresponding cameras 110 can be set on both sides of the working platform 101 so that a larger operation range can be photographed.

[0045] In one example, as Figure 1 and Figure 3 shown, the lifting mechanism 2 includes a lifting scissors bracket 201 and at least one lifting oil cylinder 202. Both ends of the lifting scissors bracket 201 are respectively connected to the moving support mechanism 3 and the wire reset mechanism 1. The lifting oil cylinder 202 is arranged in the lifting scissors bracket 201 in a matching manner. The lifting scissors bracket 201 can telescopically move in the vertical direction under the drive of the lifting oil cylinder 202.

[0046] Specifically, the lifting scissors support 201 can be lowered to the lowest height and folded up when not in emergency repair, which is convenient for moving and handling. While in emergency repair, it can be telescopically driven by the lifting oil cylinder 202 to adjust the wire reset mechanism 1 to the required height. The number of lifting oil cylinders 202 can be designed according to the size and structure of the lifting scissors support 201, and it is only necessary to ensure that the lifting oil cylinder 202 can be housed within the lifting scissors support 201 when the latter is folded. It should be noted that the lifting scissors support 201, in cooperation with the flipping support column 102 of the wire reset mechanism 1, can lift the wire to a safe height of more than 8 meters to meet the power transmission requirements of the 10KV power line.

[0047] In one example, as Figure 1 、 Figure 3 and Figure 4 shown, a telescopic ladder 203 is connected to the same side of the wire reset mechanism 1 and the mobile support mechanism 3, and the telescopic ladder 203 can be synchronously telescopically adjusted with the lifting of the lifting mechanism 2.

[0048] Specifically, the upper and lower ends of the telescopic ladder 203 are respectively connected to the wire reset mechanism 1 and the mobile support mechanism 3, and can be synchronously telescopically adjusted with the lifting of the lifting mechanism 2. Such a telescopic ladder 203 can adapt to work platforms 101 at different heights, and repair personnel can all go up and down the work platform 101 through the telescopic ladder 203. And when not in emergency repair, the telescopic ladder 203 is in a retracted and folded state, which is convenient for transportation.

[0049] In one example, as Figure 1 shown, the mobile support mechanism 3 includes a mounting chassis 301, a mobile component and a fixing component. The mounting chassis 301 is used to support and install the lifting mechanism 2, and the mobile component and the fixing component are connected to the mounting chassis 301. The mobile component can move the mounting chassis 301, and the fixing component can fix the mounting chassis 301.

[0050] Specifically, the mounting chassis 301 serves as the support foundation for the lifting mechanism 2 and the wire reset mechanism 1, and both the mobile component and the fixing component are connected to the mounting chassis 301. The mobile component can move the mounting chassis 301, that is, it can drive the lifting mechanism 2 and the wire reset mechanism 1 for moving and handling; the fixing component can fix the mounting chassis 301, that is, it can fix the positions of the lifting mechanism 2 and the wire reset mechanism 1.

[0051] In one example, as Figure 1 and Figure 3 shown, the mobile component includes a trailer hitch 303 and at least one set of mobile wheels 302. The mobile wheels 302 are arranged below the mounting chassis 301, and the trailer hitch 303 is arranged at the traction end of the mounting chassis 301.

[0052] Specifically, the moving wheels 302 can facilitate the movement of the mounting chassis 301. The number of moving wheels 302 can be set according to specific requirements. Generally, two sets of moving wheels 302 (i.e., four moving wheels 302) can be set, which can form a stable support for the mounting chassis 301 while facilitating movement. If only one set of moving wheels 302 (i.e., two moving wheels 302) is provided, a retractable auxiliary support wheel 304 can be set under the mounting chassis 301. The auxiliary support wheel 304 can cooperate with the moving wheels 302 to form a stable support for the mounting chassis 301. A trailer hitch 303 for towing can be set at one end of the mounting chassis 301. Through the trailer hitch 303, it can move under the drive of a towing device. It should be noted that the speed at which the towing device pulls the wire reset device through the trailer hitch 303 can reach 60 km / h.

[0053] In one example, as Figure 1 、 Figure 2 and Figure 4 shown, the fixing component includes a plurality of fixing legs 305. One end of the fixing leg 305 is retractable on the mounting chassis 301, and the other end is provided with an auxiliary screw leg 306. The auxiliary screw leg 306 can adjust the support height of the fixing leg 305.

[0054] Specifically, the fixing component may include four fixing legs 305. The four fixing legs 305 are symmetrically distributed in pairs on the mounting chassis 301 to facilitate balanced support for the mounting chassis 301. The fixing legs 305 are in a retracted state when not in emergency repair, that is, they are retracted on the mounting chassis 301. The fixing legs 305 are in an extended state when in emergency repair, that is, they are extended to support around the mounting chassis 301. One end of the fixing leg 305 supporting on the ground is provided with an auxiliary screw leg 306. The auxiliary screw leg 306 can adjust the support height of the fixing leg 305 for the mounting platform by means of screw adjustment, so that the mounting platform is in a balanced state, that is, the tabletop of the working platform 101 of the wire reset mechanism 1 is in a horizontal plane.

[0055] In one example, as Figure 1 shown, the wire reset device may further include a power mechanism. The power mechanism may include a hydraulic power component 307 and an electrical power component 308. The hydraulic power component 307 can provide telescopic power for the hydraulic lifting arm 107 and the lifting cylinder 202. The electrical power component 308 can provide driving force for the self-movement of the device itself and can also meet the self-power supply requirements for field operations, solving the difficulty of using electricity in the wild.

[0056] Furthermore, the electrical power component 308 may include a generator and a generator distribution box, a battery pack and a battery main switch control, etc.

[0057] It should be noted that the power mechanism can adopt two forms: an in-built power unit and an external power unit.

[0058] Although the present utility model has been described with reference to the preferred embodiments, various modifications thereof can be made and components thereof can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any manner.
