Description

Technical Field

[0001] This invention relates to the field of power maintenance equipment technology, and in particular to a highly efficient and flexible bypass cable trolley device. Background Technology

[0002] Bypass operation refers to the operation method of transferring the load in the power distribution line to the bypass system through the access of bypass equipment, so as to realize the power outage maintenance of the equipment to be maintained. In the operation of the power system, regular line maintenance or emergency fault repair is an essential part of the work, and these tasks often require temporarily switching some circuits to the backup line to ensure the continuity of power supply.

[0003] Patent No. CN202321322145.4 discloses a cable reel transport trolley that can stabilize the position of the cable reel and strengthen the fixation of the cable reel to prevent it from rolling during transportation.

[0004] The above-mentioned bypass operation cable reel transportation process has the following drawbacks: its cable bonding and fixing method is too simple, and it will shake violently during transportation on uneven road surfaces, posing a safety hazard. It lacks an integrated power transmission circuit design and has insufficient mobility, requiring external vehicles for towing. The existing manual cable laying method requires a large number of people to move bypass cables, bypass load switches, intermediate connectors, etc. before and after bypass operation. The process requires multiple workers to transport multiple times and multiple sets of tools to work together, resulting in low operation efficiency. It is not only time-consuming and labor-intensive, but also poses certain safety hazards. Therefore, we propose an efficient and flexible bypass operation cable trolley device. Summary of the Invention

[0005] The main objective of this invention is to provide a highly efficient and flexible cable trolley device for bypass operations. By improving the trolley structure, it can transport bypass cables more stably, conveniently, and safely, effectively solving the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A highly efficient and flexible bypass cable trolley device includes a vehicle body, a base frame detachably connected to the top of the vehicle body, and mating holes are provided at corresponding positions on the bottom of the base frame and the top of the vehicle body, with fastening bolts screwed between the mating holes. Brackets are symmetrically welded to the sides of the base frame, and swivel rings are movably connected to the top of the brackets through fastening bolts. A reel for winding bypass cables is installed between the symmetrical swivel rings on both sides of the base frame.

[0008] Furthermore, a bypass switch control cabinet is fixed to the side of the base frame with fasteners. Both sides of the bypass switch control tube are provided with cable connectors for connecting to the cable ends. The bypass switch control cabinet for cable connection and power on / off control is fixed to the side of the base frame with bolts and other fasteners. Cable connectors for connecting to the cables are provided on both sides of the cabinet. When needed, the bypass cable can be connected through the bypass switch control cabinet, and the power on / off of the cable can be controlled by the bypass switch control cabinet, so that the cable forms a complete and reliable power transmission circuit, which greatly improves the speed of on-site operation.

[0009] Furthermore, a battery is installed on one side of the bottom of the vehicle body, and a moving wheel is installed on the bottom of the vehicle body with a power motor installed at the power input end of the moving wheel. The power supply end of the battery is connected to the power connection end of the power motor. The battery can be charged and store electrical energy. When needed, the moving wheel is driven to rotate through the power motor and transmission mechanism, thereby moving the vehicle body without the need for external traction equipment.

[0010] Furthermore, a steering wheel connected to the side wheels at the bottom of the vehicle body is provided on one side of the top of the vehicle body, and a seat is installed on the side of the top of the vehicle body near the steering wheel; the steering wheel structure can control the steering of the vehicle body, and the seat structure makes it convenient for the operator to sit and operate the vehicle body.

[0011] Furthermore, the outer periphery of the drum is welded with spacers, and cable trays are installed on both sides of the top of the base frame at the bypass switch control cabinet. The spacers divide the outer periphery of the drum into different sections, which facilitates the winding of cables of different specifications. The cable trays can play an auxiliary supporting role when the cables are connected to the bypass switch control cabinet.

[0012] Furthermore, limit rods are welded horizontally to both ends of the base frame, and hollow sleeve rods are sleeved around the outer circumference of each limit rod. A fixing frame is welded to the side of the bracket, and corresponding limit holes are opened inside the fixing frame and on the inner circumference of the swivel, with pins inserted between the limit holes. The limit rods are designed at both ends of the base frame, and the hollow sleeve rods can rotate around the outer circumference of the limit rods. During cable winding and unwinding operations, the rotating hollow sleeve rods make the winding and unwinding of the cable smoother. After the drum finishes winding the cable, the swivel at the end can be rotated to align the limit hole on its inner circumference with the limit hole inside the fixing frame. Inserting a pin at the connection point can fix the swivel and the drum, preventing them from rotating and thus maintaining the stability of the cable.

[0013] Compared with existing technologies, this invention has the following advantages: the battery can be charged and store electrical energy. When needed, it drives the rotation of the moving wheels through a power motor and transmission mechanism, thereby moving the vehicle body without the need for external traction equipment. The top of the underframe is equipped with drums of different specifications. Before performing a task, a suitable underframe can be selected and connected to the vehicle body according to different operational requirements. The underframe is fixed by aligning the docking holes at the bottom of the underframe with the docking holes inside the vehicle body and tightening the bolts. The drum at the top of the support can rotate to wind up the cable. After winding, locking the drum angle allows for bypass cable transport via vehicle movement. When the work position is reached, the bypass switch installed on the side of the underframe can control the connection and opening / closing of the cable. The built-in drive... The mobile system can move freely in various complex terrains without additional manpower to pull it. It adopts a modular design, and the parts can be replaced according to different operation requirements. It is suitable for multiple voltage levels and cable types, which reduces the difficulty of transportation, greatly reduces manpower loss, and reduces the possibility of flexible cables falling from heights and being hit by objects during loading and unloading, ensuring the safety of personnel and equipment. A bypass switch control cabinet for cable connection and power on / off control is fixed on the side of the base frame with bolts and other fasteners. Cable connectors for cable connection are provided on both sides of the cabinet. When needed, the bypass cable can be connected through the bypass switch control cabinet, and the power on / off of the cable can be controlled by the bypass switch control cabinet, so that the cable forms a complete and reliable power transmission circuit, which greatly improves the speed of on-site operation.

[0020] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0021] like Figure 1-5 As shown, a highly efficient and flexible bypass cable trolley device includes a vehicle body 1. A base frame 3 is detachably connected to the top of the vehicle body 1. The bottom of the base frame 3 and the top of the vehicle body 1 are provided with docking holes 301 at corresponding positions, and fastening bolts 302 are screwed between the docking holes 301. The sides of the base frame 3 are symmetrically welded with brackets 303, and the top of the brackets 303 is movably connected to a swivel ring 305 through the fastening bolts 302. A reel 306 for winding bypass cables is installed between the symmetrical swivel rings 305 on both sides of the base frame 3.

[0022] The base frame 3 is fixed to the side of the bypass switch control cabinet 4 by fasteners. Both sides of the bypass switch control tube are provided with cable connectors 401 that connect with the cable ends. The bypass switch control cabinet 4, which is used for cable connection and power on / off control, is fixed to the side of the base frame 3 by bolts and other fasteners. Cable connectors 401 are provided on both sides of the cabinet for cable connection. When needed, the bypass cable can be connected through the bypass switch control cabinet 4, and the power on / off of the cable can be controlled by the bypass switch control cabinet 4, so that the cable forms a complete and reliable power transmission circuit, which greatly improves the speed of on-site operation.

[0023] The vehicle body 1 has a battery 101 installed on one side of its bottom. The bottom of the vehicle body 1 has casters 103, and a motor 102 is installed at the power input end of the casters 103. The power supply end of the battery 101 is connected to the power input end of the motor 102. A steering wheel 2, connected to the casters 103 on the bottom side of the vehicle body 1, is installed on one side of the top of the vehicle body 1. A seat 201 is installed on the top of the vehicle body 1 near the steering wheel 2. The battery 101 can be charged and store electrical energy. When needed, the motor 102 and transmission mechanism drive the casters 103 to rotate, thus moving the vehicle body 1 without external traction equipment. The steering wheel 2 allows for steering control of the vehicle body 1, and the seat 201 allows the operator to sit comfortably and operate the vehicle body 1.

[0024] The drum 306 is fitted with spacers 307 at intervals around its outer periphery, and cable trays 402 are installed on both sides of the top of the base frame 3 at the bypass switch control cabinet 4. The spacers 307 divide the outer periphery of the drum 306 into different sections to facilitate the winding of cables of different specifications. The cable trays 402 can play an auxiliary supporting role when the cable is connected to the bypass switch control cabinet 4.

[0025] The base frame 3 has horizontally welded limit rods 5 at both ends, and hollow sleeve rods 501 are sleeved around the outer periphery of each limit rod 5. A fixing frame 6 is welded to the side of the bracket 303. Limiting holes 601 are opened at corresponding positions inside the fixing frame 6 and at the inner periphery of the rotating ring 305, and pins 602 are inserted between the limiting holes 601. The limit rods 5 are designed at both ends of the base frame 3. The hollow sleeve rods 501 can rotate around the outer periphery of the limit rods 5. When the cable is being wound up or down, the rotating hollow sleeve rods 501 make the winding and unwinding of the cable smoother. After the drum 306 has finished winding the cable, the rotating ring 305 at the end can be rotated so that the limiting hole 601 on its inner periphery is aligned with the limiting hole 601 inside the fixing frame 6. The pins 602 are inserted at the connection to fix the rotating ring 305 and the drum 306, preventing them from rotating and thus maintaining the stability of the cable.

[0026] It should be noted that this invention is a highly efficient and flexible bypass cable trolley device. During use, the battery 101 can be charged and store electrical energy. When needed, the motor 102 and transmission mechanism drive the rotating wheels 103, thereby moving the trolley 1 without external traction equipment. The top of the base frame 3 is equipped with drums 306 of different specifications. Before performing the task, a suitable base frame 3 can be selected and connected to the trolley 1 according to different operational requirements. The base frame 3 is fixed by aligning the docking holes 301 at the bottom of the base frame 3 with the docking holes 301 inside the trolley 1 and tightening the fastening bolts 302. The drum 306 located at the top of the bracket 303 can rotate to wind up the cable. After winding, locking the angle of the drum 306 allows the bypass cable to be transported by moving the trolley 1. When reaching the working position, the bypass cable can also be transported via the side of the base frame 3. The bypass switch controls the connection and opening / closing of cables. With its built-in drive system, it can move freely in various complex terrains without additional manpower. Its modular design allows for component replacement to meet different operational needs, making it suitable for various voltage levels and cable types. This reduces transportation difficulty, significantly minimizes manpower losses, and reduces the risk of flexible cables falling from heights or being struck by objects during loading and unloading, ensuring the safety of personnel and equipment. A bypass switch control cabinet 4, which controls cable connection and power on / off, is fixed to the side of the base frame 3 using bolts and other fasteners. Cable connectors 401 are located on both sides of the cabinet for cable connection. When needed, the bypass cable can be connected through the bypass switch control cabinet 4, and the power on / off of the cable can be controlled by the bypass switch control cabinet 4, forming a complete and reliable power transmission circuit and greatly improving the speed of on-site operations.
