[0038] The following describes the wiring engineering vehicle 100 according to an embodiment of the present utility model in conjunction with the accompanying drawings.

[0039] Reference Figure 1 , Figure 2 As shown, according to the embodiment of the utility model, the cable-string engineering vehicle 100 comprises: a passenger platform 10 , a working platform 41 and a lifting device 40 .

[0040] The bus platform 10 has a driving mechanism and a receiving space 11. The driving mechanism has a power take-off portion 21. The top wall 112 of the receiving space 11 is provided with an opening 111. The working platform 41 is used to carry the operating personnel, and the working platform 41 is located outside the opening 111. The lifting device 40 is arranged on the bus platform 10 and penetrates the receiving space 11. The upper end of the lifting device 40 passes through the opening 111 to connect to the working platform 41, and the lifting device 40 is connected to the power take-off portion 21 to drive the working platform 41 to rise and fall.

[0041] The driving mechanism is arranged on the bus platform 10, and the driving mechanism has a power take-off portion 21. The lifting device 40 is installed on the bus platform 10, and the lifting device 40 is connected to the power take-off portion 21 to drive the working platform 41 to rise and fall.

[0042] Among them, the lifting device 40 is installed on the bus platform 10, and the lifting device 40 is connected to the power take-off part 21 on the driving mechanism, and the power take-off part 21 transmits power to the lifting device 40 to drive the lifting device 40 to move. The lifting device 40 is connected to the working platform 41, and the working platform 41 is used to carry the operating personnel. It can be understood that the movement of the lifting device 40 drives the working platform 41 to rise and fall, thereby raising or lowering the operating personnel carried, which is convenient for the workers to climb at high altitudes and realize the erection and maintenance of the trolleybus line network.

[0043] In the related art, the vehicle only plays a role of transportation. After the vehicle transports the fixed lifting equipment to the destination, the fixed lifting equipment is transferred from the vehicle to the ground for assembly. Before working on the trolleybus network, there is a lot of preparation work and it takes a long time. At the same time, the fixed lifting equipment cannot realize instant stop operation, the operating range is small, resulting in low efficiency.

[0044] It should be noted that some urban roads have regulations on truck restrictions. In the embodiment of the utility model, the lifting device 40 is installed on the bus platform 10. The bus platform 10 is different from the truck. The bus platform 10 is used to carry the lifting device 40, thereby increasing the range of activities of the wireline engineering vehicle 100, solving the problem of truck restrictions on some urban roads, and meeting more operating scenarios. At the same time, compared with truck transportation, the bus platform 10 of the utility model embodiment can carry more people, which is convenient for transportation.

[0045] At the same time, the lifting device 40 is directly installed on the bus platform 10. The bus platform 10 is used to transport the lifting device 40. The lifting device 40 can directly lift the working platform 41 on the bus platform 10 without the need for transfer or assembly, thereby saving a lot of workload. The lifting device 40 can work after the bus platform 10 stops, thereby improving work efficiency.

[0046] At the same time, the lifting device 40 utilizes the power of the bus platform 10, so that the lifting device 40 does not need to be equipped with power components, thereby simplifying the structure and reducing the number of parts.

[0047] In the above scheme, the bus platform 10 has a accommodating space 11, the accommodating space 11 has a top wall 112, an opening 111 is provided on the top wall 112, the lifting device 40 corresponds to the opening 111, the lifting device 40 has a certain length, part of the lifting device 40 is located in the accommodating space 11, the rest of the lifting device 40 extends out of the accommodating space 11 through the opening 111, and the rest of the lifting device 40 is located outside the accommodating space 11.

[0048] It can be understood that the accommodating space 11 can accommodate people or objects. For example, the above-mentioned workers can be in the accommodating space 11, so that the workers can follow the line engineering vehicle 100 without the need to use a separate personnel transport vehicle to transport the workers. Alternatively, the accommodating space 11 can accommodate work tools or work materials, such as a ladder 200, so as to meet the all-weather and all-time needs of different scenarios and different requirements.

[0049] The top wall 112 of the accommodating space 11 can block wind and rain, thereby protecting people or materials that need to be waterproof, such as wires, insulators, transformers, inverters, etc.

[0050] According to the wireline engineering vehicle 100 of the embodiment of the utility model, a bus platform 10 is provided to carry the lifting device 40. The bus platform 10 is different from a truck. The bus platform 10 is used to carry the lifting device 40, thereby increasing the range of activities of the wireline engineering vehicle 100, solving the problem of truck restrictions on some urban roads, and meeting more operating scenarios. At the same time, it can carry more people and facilitate transportation. The lifting device 40 can directly lift the working platform 41 on the bus platform 10 without the need for transfer or assembly, thereby saving a lot of workload. The lifting device 40 can work after the bus platform 10 stops, thereby improving work efficiency. The lifting device 40 uses the power of the bus platform 10 to simplify the structure and reduce the number of parts.

[0051] Reference Figure 1 , Figure 2 As shown, in some embodiments, the bus platform 10 has a receiving space 11, a top wall 112 of the receiving space 11 is provided with an opening 111, the lifting device 40 is at least partially disposed in the receiving space 11, and the lifting device 40 is suitable for extending through the opening 111 to outside the receiving space 11.

[0052] In some embodiments, the lifting device 40 includes a fixed bracket with a certain height, and the working platform 41 is liftably arranged on the fixed bracket. A transmission chain is arranged on the lifting device 40, and the transmission chain is connected to the working platform 41 and pulls the working platform 41 to rise and fall.

[0053] In some embodiments, the lifting device 40 includes a hydraulic cylinder 44 and a lifting bracket 42 , and the lifting bracket 42 includes at least a first-stage bracket 424 and a second-stage bracket 426 .

[0054] The first stage bracket 424 is installed on the bus platform 10. The second stage bracket 426 is escalably installed on the first stage bracket 424, and a mounting plate 4263 is installed on the second stage bracket 426, and the working platform 41 is installed on the mounting plate 4263.

[0055] The hydraulic cylinder 44 is arranged on the bus platform 10 , and has a telescopic end, which is connected to the mounting plate 4263 , and one end of the hydraulic cylinder 44 opposite to the telescopic end is connected to the power take-off unit 21 to drive the working platform 41 to rise and fall.

[0056] In the above scheme, the telescopic end of the hydraulic cylinder 44 is connected to the mounting plate 4263 on the second-level bracket 426. It can be understood that the telescopic end pushes the mounting plate 4263 to move up and down, and the mechanical structure is used to drive the lifting bracket 42 to move up and down. The overall driving force is stronger and the movement is more stable. At the same time, the overall structure is clearer and the structure is simplified.

[0057] Specifically, the lifting bracket 42 is constructed as a three-stage bracket, which includes a first-stage bracket 424, a second-stage bracket 426 and a third-stage bracket 425 arranged between the first-stage bracket 424 and the second-stage bracket 426. The first-stage bracket 424 is connected to the bus platform 10, the third-stage bracket 425 is liftably arranged on the first-stage bracket 424, the second-stage bracket 426 is liftably arranged on the third-stage bracket 425, and the working platform 41 is arranged on the mounting plate 4263 of the second-stage bracket 426. The cooperation of the first-stage bracket 424, the second-stage bracket 426 and the third-stage bracket 425 enables the working platform 41 to be lifted and lowered stably, achieving a lifting weight of 3.5T.

[0058] Reference Figure 1 , Figure 2 As shown, in some embodiments, the first-level bracket 424 has a first connecting portion 421 and a second connecting portion 422 , the first connecting portion 421 and the second connecting portion 422 are respectively connected to different parts of the bus platform 10 , and the second connecting portion 422 is higher than the first connecting portion 421 .

[0059] In the above scheme, the first connecting part 421 and the second connecting part 422 on the lifting bracket 42 are respectively connected to different parts of the bus platform 10, and the position of the second connecting part 422 is higher than the position of the first connecting part 421, so that the connection points between the lifting bracket 42 and the bus platform 10 are at different heights, avoiding the generation of torque on the lifting bracket 42 during the movement of the bus platform 10, so that the lifting bracket 42 is more stably fixed on the bus platform 10.

[0060] In some specific embodiments, the first-level bracket 424 has a first connecting portion 421 and a second connecting portion 422 , the first connecting portion 421 is connected to the bottom wall 113 of the accommodating space 11 , and the second connecting portion 422 is connected to the top wall 112 of the accommodating space 11 to support the first-level bracket 424 .

[0061] Reference Figure 1 , Figure 2 As shown, in some embodiments, the first connecting portion 421 is connected to the bottom wall 113 of the accommodating space 11 , and the second connecting portion 422 is connected to the top wall 112 .

[0062] In the above scheme, the second connecting part 422 is higher than the first connecting part 421. The first connecting part 421 is connected to the bottom wall 113 of the accommodating space 11, and the second connecting part 422 is connected to the top wall 112, so that the distance between multiple connection points between the lifting bracket 42 and the bus platform 10 is larger, which further avoids the generation of torque and further increases the stability of the bus platform 10.

[0063] In some specific embodiments, the first connection portion 421 is welded to the top wall 112 to improve reliability. Further, the first connection portion 421 is welded to the top wall 112 flush with the top wall 112 . The first connection portion 421 is welded to the top wall 112 flush with the top wall 112 .

[0064] In some other specific embodiments, the first connection portion 421 is connected to the top wall 112 by bolts and nuts, which reduces the workload of manufacturing the wireline engineering vehicle 100 .

[0065] In some specific embodiments, the second connection portion 422 is welded to the bottom wall 113 to improve reliability. Further, the second connection portion 422 is welded to the bottom wall 113 flush with each other. The second connection portion 422 is welded to the bottom wall 113 flush with each other.

[0066] In some other specific embodiments, the second connection portion 422 is connected to the bottom wall 113 by bolts and nuts, which reduces the workload of manufacturing the wiring engineering vehicle 100 .

[0067] In some embodiments, the bus platform 10 includes a top plate, side plates, a front plate and a rear plate.

The top plate, side plates, front plate and rear plate jointly define a storage space 11, and an opening 111 is arranged on the top plate.

[0068] In the above scheme, the bus platform 10 includes a top plate, side plates, a front plate and a rear plate, which together define a storage space 11. The top plate is located on the roof and can play a role of blocking. Similarly, the side plates are located on the side enclosures and can also play a role of blocking. The front plate is provided at the front of the overhead line engineering vehicle 100, and the rear plate is provided at the rear of the overhead line engineering vehicle 100, thereby protecting people and materials in the storage space 11. Compared with the scheme of the truck in the related art, the truck in the related art is open and has no large space for transporting people and materials. The bus platform 10 of the embodiment of the utility model has a large space, and the top plate and the side plates define the storage space 11. The top plate and the side plates prevent dust, liquid or foreign matter outside the storage space 11 from interfering with people and materials in the storage space 11.

[0069] Among them, the front plate of the vehicle is arranged at the front of the wire engineering vehicle 100, and the rear plate of the vehicle is arranged at the rear of the wire engineering vehicle 100. The top plate, the side plate, the front plate of the vehicle and the rear plate of the vehicle jointly define the accommodating space 11. That is to say, the accommodating space 11 extends from the front of the vehicle to the rear of the vehicle, so that the volume of the accommodating space 11 is larger, and more people or items can be transported. Compared with the scheme of using trucks to transport personnel in related technologies, the truck has a small space and the number of people transported does not exceed 5. The bus platform 10 of the embodiment of the utility model has a large space and can transport 9 people.

[0070] Specifically, the top wall 112 is the surface of the top plate, and the opening 111 is opened on the top plate to facilitate the extension of the lifting device 40.

[0072] In the above scheme, a positioning groove 14 is provided on the frame, and the positioning groove 14 is used to position multiple corner columns 4241 of the first-level bracket 424, so as to avoid the corner columns 4241 from being misplaced and the corner columns 4241 from being installed in the wrong position, making the first-level bracket 424 more stable and preventing the lifting bracket 42 from shaking.

[0073] Specifically, the first-stage bracket 424 is a cubic structure, and there are four corner columns 4241 . The four corner columns 4241 are respectively disposed on the four corners of the first-stage bracket 424 to support the first-stage bracket 424 , thereby making the whole structure more stable.

[0074] Reference Figure 1 , Figure 2 ,and Figure 3 As shown, in some embodiments, a personnel seat 114, a workbench 115 for processing parts, and a toolbox 116 are provided in the accommodating space 11. The personnel seat 114 is provided at one end of the bus platform 10 close to the front of the bus, the workbench 115 is provided between the lifting device 40 and the personnel seat 114, and the toolbox 116 is provided on the side of the lifting device 40 away from the workbench 115.

[0075] In the above scheme, the personnel transported by the wiring engineering vehicle 100 can sit on the personnel seats 114, and the workbench 115 provides a support surface for material processing. For example, the workbench 115 is a work table, and the materials can be placed on the work table for processing or processing. The tool box 116 is used to place tools. The tools are placed in the tool box 116 for easy retrieval and unified management, while reducing the probability of tools injuring people when the wiring work vehicle brakes suddenly.

[0076] Among them, the personnel seat 114 is arranged at one end of the bus platform 10 close to the front of the bus, which improves the comfort of the personnel, and the workbench 115 is arranged between the lifting device 40 and the personnel seat 114, that is, the workbench 115 is closer to the lifting device 40 than the personnel seat 114, the personnel seat 114 can be understood as a rest area, and the workbench 115 and the lifting device 40 can be understood as a work area. The rest area and the work area are clearly divided to avoid confusion of personnel during work and improve work efficiency. At the same time, the tool box 116 is arranged on the side of the lifting device 40 away from the workbench 115, and the lifting device 40 is used to isolate personnel and tools to prevent personnel from being harmed by tools.

[0077] Specifically, the personnel seats 114 include a driver seat and a passenger seat. The passenger seat is arranged on a side of the driver seat close to the lifting device 40, so that the space distribution in the accommodating space 11 is clearer.

[0078] More specifically, there are a plurality of passenger seats, thereby providing seating for more persons.

[0079] In some embodiments, the top wall 112 of the accommodating space 11 is further provided with a skylight 117, and the bottom wall 113 of the accommodating space 11 is provided with a slot 1131, and the slot 1131 is used to position the ladder 200, and the ladder 200 overlaps the skylight 117 to allow workers to pass through.

[0080] Among them, a skylight 117 is provided on the top wall 112, and the skylight 117 is used for the entry and exit of workers, so as to facilitate the workers to move to the top plate and then board the work platform 41. Compared with the method in the related art that workers board the lifting device from the outside of the truck, the embodiment of the utility model is provided with a skylight 117 on the top wall 112, which facilitates people to approach the work platform 41, thereby improving safety and convenience.

[0081] At the same time, a clamping groove 1131 is provided on the bottom wall 113, so that the ladder 200 stands more stably, the probability of the ladder 200 sliding is reduced, and the safety is improved.

[0082] Reference Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the bus platform 10 also has a storage space 12, which is arranged below the accommodating space 11. The bus platform 10 also has an installation space 13 for installing the driving mechanism. The storage space 12 and the installation space 13 are respectively located on opposite sides of the lifting device 40.

[0083] In the above scheme, a storage space 12 is also provided on the bus platform 10, and a storage space 12 is specially provided below the accommodating space 11.
