Description

Technical Field

[0001] This utility model relates to the field of substation inspection and maintenance technology, and in particular to a substation inspection and maintenance device. Background Technology

[0002] Substations are important locations in a power system used to change voltage levels. They transmit electrical energy to distant locations by increasing voltage, or decrease voltage near users to meet their electricity needs.

[0003] The normal operation of substations is crucial for the stability of the power system. Therefore, routine inspections and maintenance are necessary to ensure proper equipment operation. However, existing substation maintenance platforms present several inconveniences in practice. Most platforms only have a single lifting function. When approaching a substation for maintenance, operators must first lower the platform and then move the chassis to the target location, a cumbersome process that reduces efficiency. Furthermore, during maintenance at night or in poorly lit environments, operators often need to use handheld flashlights, increasing complexity and potentially impacting efficiency and safety due to the inability to fully free their hands. Utility Model Content

[0004] In order to overcome the defects of the prior art mentioned above, the inventors conducted in-depth research and, after a great deal of creative work, completed this utility model.

[0005] Specifically, the technical problem to be solved by this utility model is to provide a substation inspection and maintenance device to address the fact that most current platforms only have a single lifting function. When it is necessary to approach the substation shown in the diagram for maintenance, the operator must first lower the platform and then move the chassis to the target position, which is cumbersome and reduces the efficiency of inspection and maintenance. In addition, when conducting maintenance at night or in environments with insufficient light, the operator often needs to use a flashlight for illumination, which increases the complexity of the operation and can easily affect work efficiency and safety due to the inability to completely free up their hands.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A substation inspection and maintenance device includes a chassis body, a maintenance platform body for personnel to stand on at the top of the chassis body, a guide frame for limiting the movement of the maintenance platform body at the top of the chassis body, an adjustment component for driving the maintenance platform body to move on the guide frame on the chassis body, and an illumination source for nighttime illumination installed on the maintenance platform body through an auxiliary component.

[0008] The main body of the maintenance platform includes a standing plate distributed parallel to the chassis body. Each of the four corners of the standing plate is fixedly installed with a protruding shaft that is integrally formed with the standing plate. Guide pulley shafts are also provided on both sides of the standing plate and between the protruding shafts.

[0009] The guide frame includes a first pillar and a second pillar that is parallel to and corresponds to the first pillar. An inclined guide rail is provided between the first pillar and the second pillar, and the end of the inclined guide rail near the first pillar is inclined downward. The ends of the first pillar and the second pillar away from the inclined guide rail are fixedly installed on the top of the chassis body.

[0010] As an improved technical solution, the inclined guide rail is provided with an inclined groove that is coaxially distributed along the inclined guide rail and adapted to the guide pulley shaft. The connection end of the inclined guide rail and the first support column is provided with a longitudinal groove that communicates with the inclined groove. The connection end of the inclined guide rail and the second support column is provided with a transverse groove that communicates with the inclined groove. The longitudinal groove is connected to the transverse groove through the inclined groove.

[0011] As an improved technical solution, the adjustment assembly includes hydraulic push rods and support shafts symmetrically distributed on both sides of the chassis body. The piston rods of the hydraulic push rods are all fixedly connected to hinge seats. The end of the hydraulic push rod away from the hinge seat is hinged to the chassis body. The piston rod of the hydraulic push rod is hinged to the support shaft through the hinge seat.

[0012] As an improved technical solution, each of the support shafts has an extension shaft slidably connected to the end away from the chassis body. The end of each support shaft away from the extension shaft is hinged to the chassis body. The end of the extension shaft extending outside the support shaft is hinged to the standing plate via a protruding shaft. The support shafts are connected to each other by a connecting rod, and each end of the connecting rod is hinged to a corresponding support shaft.

[0013] As an improved technical solution, a ladder is fixedly installed on the top of the chassis body, and self-locking moving wheels are symmetrically distributed at the four corners of the chassis body.

[0014] As an improved technical solution, a U-shaped protective fence is fixedly installed on the top of the main body of the inspection platform. The protective fence also has an opening corresponding to the ladder, and a protective door is provided on the opening. An outward-opening stop bar for restricting the rotation of the protective door is also fixedly installed on the protective fence.

[0015] As an improved technical solution, a back panel connected to the protective fence is also fixedly installed on the top of the standing board. A limit frame is fixedly installed on the back panel, and the limit frame is located below the lighting source.

[0016] As an improved technical solution, the auxiliary component includes a device frame slidably connected in the back plate, a threaded slider fixedly installed at one end of the device frame extending into the back plate, a threaded rotating rod distributed parallel to the device frame in the limiting frame, one end of the threaded rotating rod passing through the limiting frame and threadedly connected to the threaded slider, a reflector frame with reflective stickers fixedly installed at the end of the device frame away from the threaded slider, and the lighting source fixedly installed below the reflector frame.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] 1.

[0034] like Figures 1 to 6 As shown in the figure, this embodiment provides a substation inspection and maintenance device. This device includes a chassis body 1, a maintenance platform body 2 for personnel to stand on at the top of the chassis body 1, a guide frame 3 for limiting the movement of the maintenance platform body 2 at the top of the chassis body 1, an adjustment component 4 for driving the maintenance platform body 2 to move on the guide frame 3 on the chassis body 1, and a lighting source 6 for nighttime illumination installed on the maintenance platform body 2 via an auxiliary component 5. The maintenance platform body 2 includes a standing plate 201 parallel to the chassis body 1. Each of the four corners of the standing plate 201 has a protruding shaft 2011 integrally formed with the standing plate 201. Guide pulley shafts 2012 are provided on both sides of the standing plate 201 and between the protruding shafts 2011. The guide frame 3 includes a first support column 301 and a second support column 302 parallel to and corresponding to the first support column 301. Inclined guide rails 303 are provided between the first support column 301 and the second support column 302. The inclined guide rail 303 is inclined downward at one end near the first support column 301. The ends of the first support column 301 and the second support column 302 away from the inclined guide rail 303 are both fixedly installed on the top of the chassis body 1. The chassis body 1 is the basic structure of the entire device and is used to support other components. The maintenance platform body 2 is the working platform for operators to stand on when inspecting and maintaining substation equipment. The guide frame 3 is used to limit the movement direction of the maintenance platform body 2 and ensure that it moves smoothly along the predetermined track. The auxiliary component 5 is used to fix and adjust the position of the lighting source 6 to ensure sufficient lighting during nighttime operations. The standing plate 201 is the main part of the maintenance platform body 2 and is used for operators to stand on. The guide pulley shaft 2012 is used to cooperate with the slide groove in the guide frame 3 to realize the guiding movement of the standing plate 201. The first support column 301 and the second support column 302 are the main support structures of the guide frame 3, used to fix the inclined guide rail 303, and the inclined design of the inclined guide rail 303 helps to smoothly raise and lower the maintenance platform body 2.

[0035] An inclined guide rail 303 has an inclined groove 3031 coaxially distributed along the inclined guide rail 303 and adapted to the guide pulley shaft 2012. The connection end between the inclined guide rail 303 and the first support column 301 has a longitudinal groove 3032 communicating with the inclined groove 3031. The connection end between the inclined guide rail 303 and the second support column 302 has a transverse groove 3033 communicating with the inclined groove 3031. The longitudinal groove 3032 is connected to the transverse groove 3033 through the inclined groove 3031. The inclined groove 3031 is used to accommodate the guide pulley shaft 2012, ensuring… The main body 2 of the maintenance platform moves smoothly along the inclined guide rail 303, so that the main body 2 of the maintenance platform can move to the target position even when the position of the chassis main body 1 remains unchanged, thereby ensuring maintenance efficiency. The longitudinal slide 3032 is used to guide the movement of the main body 2 of the maintenance platform in the vertical direction. When the guide pulley shaft 2012 moves in the longitudinal slide 3032, the horizontal position of the main body 2 of the maintenance platform remains unchanged. The transverse slide 3033 is used to guide the movement of the main body 2 of the maintenance platform in the horizontal direction. When the guide pulley shaft 2012 moves in the transverse slide 3033, the vertical position of the main body 2 of the maintenance platform remains unchanged.

[0036] The adjustment assembly 4 includes hydraulic push rods 401 and support shafts 402 symmetrically distributed on both sides of the chassis body 1. The piston rods of the hydraulic push rods 401 are all fixedly connected to hinge seats 4011. The end of the hydraulic push rod 401 away from the hinge seat 4011 is hinged to the chassis body 1. The piston rod of the hydraulic push rod 401 is hinged to the support shaft 402 through the hinge seat 4011. The hydraulic push rod 401 is the power source for driving the movement of the inspection platform body 2. Precise lifting and movement control is achieved through the hydraulic system. The hinge seat 4011 is used to limit the piston rod of the hydraulic push rod 401 to ensure effective power transmission. When the piston rod extends, it drives the support shaft 402 to deflect on the chassis body 1.

[0037] As an improved technical solution, each end of the support shaft 402 away from the chassis body 1 is slidably connected to an extension shaft 4021. The ends of the support shafts 402 away from the extension shafts 4021 are hinged to the chassis body 1. The end of the extension shaft 4021 extending outside the support shaft 402 is hinged to the standing plate 201 via a protruding shaft 2011. The support shafts 402 are connected to each other via connecting rods 4022, and each end of the connecting rod 4022 is hinged to a corresponding support shaft 402. The support shaft 402 is an important connecting component of the adjustment assembly 4, used to support and guide the movement of the maintenance platform body 2. The extension shaft 4021 is used to extend the stroke of the support shaft 402 to adapt to the movement range of the maintenance platform body 2. The connecting rod 4022 is used to synchronize the movement of the support shaft 402, maintain the balance of the maintenance platform body 2, and adapt to different movement states of the maintenance platform body 2.

[0038] A ladder 101 is fixedly installed on the top of the chassis body 1. Self-locking casters 102 are also symmetrically distributed at the four corners of the chassis body 1. The ladder 101 is used to facilitate operators to go up and down the maintenance platform body 2. The self-locking casters 102 are used to provide flexibility when the device needs to be moved and to lock the position during operation to ensure the stability of the device.

[0039] The top of the main body 2 of the maintenance platform is fixedly equipped with a U-shaped protective railing 202. The protective railing 202 also has an opening 2021 corresponding to the ladder 101. The opening 2021 is equipped with a protective door 2022. The protective railing 202 is also fixedly equipped with an outward-opening stop bar 2023 to restrict the rotation of the protective door 2022. The protective railing 202 is used to protect the safety of the operator and prevent him from falling accidentally during the maintenance process. The opening 2021 is used to facilitate the operator to enter the main body 2 of the maintenance platform through the ladder 101. The protective door 2022 is used to close the opening 2021 during the maintenance process to further enhance safety. The outward-opening stop bar 2023 is used to prevent the protective door 2022 from flipping outward and can only open inward to ensure the safety of the operator.

[0040] The top of the standing platform 201 is also fixedly installed with a back plate 203 connected to the protective fence 202. A limit frame 2031 is fixedly installed on the back plate 203, and the limit frame 2031 is located below the lighting source 6. The back plate 203 is used to enhance the structural strength of the main body 2 of the maintenance platform.

[0041] The auxiliary component 5 includes an equipment rack 501 slidably connected to the back plate 203. A threaded slider 502 is fixedly installed at one end of the equipment rack 501 extending into the back plate 203. A threaded rotating rod 5021 parallel to the equipment rack 501 is connected to a limiting frame 2031. One end of the threaded rotating rod 5021 passes through the limiting frame 2031 and is threadedly connected to the threaded slider 502. A reflector frame 503 with reflective stickers is fixedly installed at the end of the equipment rack 501 away from the threaded slider 502. A lighting source 6 is fixedly installed below the reflector frame 503. The equipment rack 501 can be moved in the back plate 203 via the threaded slider 502 to complete the lifting and adjustment. The reflective stickers on the reflector frame 503 can provide warning at night. The lighting source 6 is fixedly installed below the reflector frame 503 to provide necessary lighting support for nighttime operations.

[0042] During use, the self-locking casters 102 of the chassis body 1 are used to lock the device in position during operation, ensuring stability. Operators enter the maintenance platform body 2 via the ladder 101 and opening 2021. Protective railings 202 and a protective door 2022 are used to protect operators and prevent accidental falls during maintenance. The protective door 2022 is restricted from opening outwards by an outward-opening stop bar 2023, allowing it to open only inwards, further enhancing safety. At this time, the guide pulley shaft 2012 in the maintenance platform body 2 is located at the lowest end of the longitudinal slide groove 3032. Adjusting the position of the maintenance platform body 2 requires extending the piston rod of the hydraulic push rod 401, which drives the support shaft 402 to deflect on the chassis body 1, causing the extension shaft 4021 to move. This causes the main body 2 of the maintenance platform to rise and fall along the inclined guide rail 303, allowing it to move vertically along the longitudinal slide groove 3032. It then moves synchronously horizontally and vertically within the inclined guide rail 303, eventually reaching the target position. It then slides horizontally within the transverse slide groove 3033, ensuring the main body 2 can move to the target position even when the chassis main body 1 remains unchanged, thus guaranteeing maintenance efficiency. By rotating the threaded rotating rod 5021, the threaded slider 502 moves along the threaded rotating rod 5021, thereby adjusting the position of the equipment frame 501 within the back plate 203. This allows for the adjustment of the lighting source 6, ensuring sufficient illumination during nighttime operations. Furthermore, the reflective frame 503 with attached reflective stickers provides warnings for nighttime work.

[0043] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
