[0002] A substation is a place in the power system that transforms voltage and current, receives electric energy and distributes electric energy. Among them, substation operation and maintenance mainly involves handling and maintaining equipment abnormalities, including inspection, replacement and commissioning of substation equipment to ensure that it meets the quality standards required for safe operation. It also includes the maintenance and acceptance of newly built, expanded and renovated substations.

[0003] Substation operation and maintenance is specifically responsible for power outage operations, line construction and maintenance, substation construction and maintenance, information communication, live work, power grid construction, material supply, distribution network construction and maintenance, etc. During maintenance operations, there are situations where workers are not tall enough and it is difficult or impossible to perform maintenance work, which cannot meet the needs of low-altitude operations.

[0004] Among them, in the specific implementation, for equipment located at high places, it is necessary to use a lifting platform during operation and maintenance. The existing lifting platforms mostly adopt a scissor-type structure. The lifting platform is moved to a suitable position. The staff stands on the top of the lifting platform, and the hydraulic cylinder pushes the scissor-type assembly to push the lifting platform up. After it is raised to a suitable height, the staff can perform high-altitude operations.

[0005] However, in actual use, the scissor-type lifting platform is large in size and is not suitable for use in a small space during substation operation and maintenance. Utility Model Content

Moreover, a first feature being “above”, “above”, and “above” a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being “below”, “below”, and “below” a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0037] like Figure 1-Figure 2 As shown, the utility model provides a lifting platform for substation operation and maintenance, comprising a mobile base 1, a lifting assembly 2 vertically arranged at one end of the mobile base 1, and a workbench 3 installed on the lifting assembly 2; the mobile base 1 comprises a base body 4 and a moving roller 5 installed on the base body 4, and the lifting platform is convenient for the operation and maintenance personnel to drag through the moving roller 5. The moving roller 5 can be a universal wheel with a self-locking function.

[0038] like Figure 3As shown, the lifting assembly 2 includes a lifting column vertically arranged on the base body 4 and a lifting drive mechanism installed in the base body 4, the lifting column includes a fixed tube 6 and a movable tube pluggably connected to the fixed tube 6, the bottom end of the fixed tube 6 is fixedly installed on the base body 4 by bolts, the movable tube includes an outer tube 7 and an inner tube 8 arranged in the outer tube 7, the inner tube 8 is coaxially arranged with the outer tube 7, the top end of the outer tube 7 is fixedly connected with the top end of the inner tube 8 by a top plate 9, the outer tube 7 is slidably sleeved on the fixed tube 6, and the inner tube 8 is movably inserted in the fixed tube 6.

[0039] The lifting drive mechanism includes a screw rod 10 and a motor 11. The screw rod 10 is vertically arranged, and the bottom end of the screw rod 10 is rotatably mounted on the base body 4 through a bearing seat 12. The motor 11 is installed in the base body 4, and the motor 11 drives the screw rod 10 to rotate axially through a reducer 16. The screw rod 10 is inserted into the inner tube 8 from bottom to top, and the inner tube 8 is connected to the screw rod 10 through a slider 13. The slider 13 is fixedly connected to the inner tube 8. When the screw rod 10 rotates, the inner tube 8 is driven to rise or fall along the axial direction of the screw rod 10 through the slider 13, so that the entire movable tube rises or falls relative to the fixed tube 6. The lifting state of the lifting platform is as follows Figure 5 shown.

[0040] The workbench 3 is fixedly mounted on the outer wall of one side of the outer tube 7, and the workbench 3 is arranged opposite to the base body 4 in the vertical direction. When the screw rod 10 rotates forward to make the slider 13 rise along the screw rod 10, the outer tube 7 rises relative to the fixed tube 6, thereby lifting the workbench 3; when the screw rod 10 rotates reversely to make the slider 13 fall along the screw rod 10, the outer tube 7 falls relative to the fixed tube 6, thereby dropping the workbench 3.

[0041] In this embodiment, the motor 11 is a servo motor. The rotation direction of the motor 11 is controlled to control the screw rod 10 to rotate forward or reverse, thereby controlling the lifting of the lifting platform; and the lifting height of the lifting platform can be controlled by controlling the output time of the motor 11.

[0042] In this embodiment, both the outer tube 7 and the fixed tube 6 are square tubes. The four outer side walls of the fixed tube 6 are provided with longitudinally extending slide rails 14, and the inner wall of the outer tube 7 is provided with slide bars 15 corresponding to the slide rails 14. Figure 4 As shown, the slide bar 15 slides along the slide rail 14, so that the outer tube 7 and the fixed tube 6 maintain a stable up and down sliding connection relationship. When the screw rod 10 rotates, the slider 13 will not rotate synchronously with the screw rod 10, so that the slider 13 can drive the entire movable tube to move up and down along the axis of the screw rod 10.

[0043] Specifically, Figure 2As shown, the workbench 3 includes a support platform 17 and a fence frame 18. The fence frame 18 is fixedly welded to the outer wall of one side of the outer tube 7. The support platform 17 is fixedly connected to the bottom of the fence frame 18 by screws. One side of the fence frame 18 has an open setting to form an entrance and exit, and the operation and maintenance personnel enter the workbench 3 through the entrance and exit.

[0044] In order to protect the maintenance personnel during work, a protective door 19 is hinged on the entrance and exit of the fence frame 18. After the maintenance personnel enter the workbench 3, the protective door 19 is closed to prevent the maintenance personnel from falling without paying attention.

[0045] In addition, a tool rack 20 is provided on the top plate 9 to facilitate the operation and maintenance personnel to place tools. A switch box 21 is provided on the outer wall of one side of the outer tube 7, and the switch box 21 is connected to the motor 11 through a wire. A switch is provided in the switch box 21, and the operation and maintenance personnel can control the rotation direction and rotation time of the motor 11 by standing in the workbench 3 and operating the corresponding switch button, thereby controlling the lifting and lifting height of the workbench 3.

[0046] The utility model provides a lifting platform for substation operation and maintenance with a compact structure and a small size, and is suitable for use in a narrow space. It is also easy to move and convenient for operation and maintenance personnel to drag and adjust the use position.

[0047] Finally, it should be noted that the various technical features of the technical solution of the present application can be combined arbitrarily. In order to make the description concise, not all possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of the present application.

[0048] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments may still be modified, or some or all of the technical features may be replaced by equivalents. Such modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention, and should all be included in the scope of the claims and specification of the present invention.
