[0002] Electric power installation and maintenance platforms are widely used in the installation, maintenance and repair operations of various electric power equipment. For example, in electric power facilities such as substations and power plants, operators can use electric power installation and maintenance platforms to repair and maintain equipment such as transformers and switch cabinets. In addition, in the construction and maintenance of power lines, electric power installation and maintenance platforms also play an important role.

[0003] In the related art, the electric power installation and maintenance platform is fixed on a mobile device or a mobile base. When the maintenance platform is damaged, it cannot be disassembled and replaced, which may cause the entire device to malfunction and affect the progress of the maintenance work. Moreover, during the installation and maintenance process, since some power failures are unknown before inspection, it is possible that additional or replacement maintenance tools and components may be needed temporarily during the maintenance process. In addition, maintenance tools may be left out during the maintenance process. Therefore, when taking, replacing tools and parts, it is necessary to lower the maintenance platform before taking them. However, for the sake of construction safety, the lifting speed of the existing maintenance platform is usually relatively slow, which makes it time-consuming to take and replace tools and parts and reduces the maintenance efficiency. Therefore, the technical personnel in this field provide an electric power installation and maintenance platform to solve the problems raised in the above background technique.

Detailed implementation manners

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution:

[0029] A power installation and maintenance platform, comprising:

[0030] A mobile base 1, and a plurality of mobile universal wheels 2 are fixedly installed at the lower end of the mobile base 1;

[0031] A protective frame 3, and the protective frame 3 is connected to a mobile frame through a clamping mechanism;

[0032] Lifting mechanism, the lifting mechanism includes a servo electric cylinder 24 and a lifting component 25. Both ends of the lifting component 25 are respectively connected with mounting plates 5. The mounting plates 5 are respectively connected with the mobile base 1 and the protective frame 3 through mounting bolts 6. The servo electric cylinder 24 is installed on one of the mounting plates 5, and the output end of the servo electric cylinder 24 is connected with the lifting component 25 through a connecting piece 4.

[0033] Loading and unloading mechanism, the loading and unloading mechanism includes a servo motor 7, a winding rope 8 and a loading and unloading frame 9. The servo motor 7 is installed on one side of the protective frame 3, and the output end of the servo motor 7 is connected with a winding roller 10. Both ends of the winding rope 8 are respectively connected with the winding roller 10 and the loading and unloading frame 9.

[0034] On the basis of the above embodiment, use the mounting bolts 6 to fixedly connect the mounting plates 5 with the protective frame 3 and the mobile base 1 respectively, so as to connect the lifting mechanism with the protective frame 3 and the mobile base 1. When performing electrical installation and maintenance, the device can be moved through a number of mobile universal wheels 2. After moving to a suitable position;

[0035] The maintenance personnel stand inside the protective frame 3 and pull the moving frame 26. The moving frame 26 is snap-connected with the protective frame 3 through a snap-fit mechanism, thereby increasing the protective height of the protective frame 3;

[0036] Then the servo electric cylinder 24 drives the lifting component 25 to move, thereby adjusting the height of the protective frame 3, enabling the operator to reach different heights for installation and maintenance operations;

[0037] Wherein, second limiting grooves 16 are opened on both sides of the mounting plate 5, and one end of the lifting component 25 is movably connected in the second limiting grooves 16 through a second moving block 17; when the lifting component 25 is adjusted up and down, the second limiting block moves in the second limiting grooves 16, which can limit the movement of the lifting component 25;

[0038] When the worker needs to pick up maintenance tools, put the maintenance tools into the loading and unloading frame 9. The servo motor 7 drives the winding rope 8 to wind and unwind through the winding roller 10, thereby driving the loading and unloading frame 9 to lift and lower. Without the time-consuming reduction of the platform height, the loading and unloading mechanism can be used to quickly convey maintenance tools or parts, improving the maintenance efficiency;

[0039] When disassembling and replacing the maintenance platform, remove the mounting bolts 6, and the lifting mechanism can be disassembled from the protective frame 3 and the mobile base 1. When the platform components are damaged, it is convenient to disassemble and replace, and it is also convenient to replace and install the maintenance platform on mobile equipment.

[0040] Further, a plurality of moving grooves 14 are formed in the protection frame 3. The moving frame includes a moving frame 26, two fixing rods 27 and a plurality of connecting rods 15. The two fixing rods 27 and the plurality of connecting rods 15 are all movably connected in the moving grooves 14, and the two fixing rods 27 and the plurality of connecting rods 15 are fixedly installed at the lower end of the moving frame 26.

[0041] The engaging mechanism includes a reset spring 18 and an engaging block 19. Installation grooves 20 for installing the reset spring 18 are formed at both ends of the two fixing rods 27, and the other end of the reset spring 18 is connected to the engaging block 19. An engaging groove 21 is formed in the protection frame 3, and the engaging block 19 is engaged in the engaging groove 21.

[0042] When increasing the protection height, press the engaging block 19 at one end of the connecting rod 15, and the engaging block 19 moves out of the card slot. Then pull the moving frame 26, and the plurality of connecting rods 15 move in the moving groove 14. When the engaging block 19 at the other end of the connecting rod 15 moves to the engaging groove 21, the reset spring 18 releases elastic potential energy and pushes the engaging block 19 to be engaged in the engaging groove 21, so as to engage and fix the moving frame with the protection frame 3, and the moving frame can increase the protection height.

[0043] Wherein, first moving blocks 22 are fixedly arranged on both sides of the connecting rods 15 on both sides of the two fixing rods 27, and first limiting grooves 23 for the first moving blocks 22 to move are formed on both sides of the first moving groove 14 connected to the fixing rods 27.

[0044] When the connecting rod 15 moves in the moving groove 14, the first moving block 22 moves in the first limiting groove 23, which can limit the connecting rod 15 to prevent the moving frame from being pulled out of the moving groove 14.

[0045] On the basis of the above embodiments, an electric telescopic rod 11 is fixedly installed at the lower end of the moving base 1, and a fixing plate 12 is installed at the output end of the electric telescopic rod 11. A rubber layer 13 is provided on the side of the fixing plate 12 facing away from the electric telescopic rod 11.

[0046] When the moving base 1 moves to a suitable position, the electric telescopic rod 11 drives the fixing plate 12 to move, and the fixing plate 12 contacts the ground, so that the device can be fixed during maintenance. Through the arrangement of the rubber layer 13, the friction force of the fixing plate 12 can be increased, and the fixing effect can be improved.

[0047] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
