Description

Technical Field

[0001] The present invention belongs to the technical field of electric power operation and maintenance, and in particular relates to an electric power operation and maintenance auxiliary device that is easy to fix and a use method thereof. Background Art

[0002] Operation and maintenance services are an important part of the daily management of operation and maintenance services. Implementing strict operation and maintenance services is a need for the development of power companies and a necessary part of establishing a standardized and effective internal control system. However, the current operation and maintenance service management is a relatively weak link in management work. It is of great significance to ensure that the control of operation and maintenance services is reasonable, complete and accurate. Power operation and maintenance refers to the maintenance of power lines, power operation and power repair by professional teams. Power lines refer to the lines used to transmit electric energy between power plants, substations and power users. It is an important part of the power supply system and is responsible for the transmission and distribution of electric energy. Power repair refers to the immediate organization of personnel and equipment for emergency repair after a power accident occurs to restore the original operation to the maximum extent. This kind of repair is urgent and the damaged parts need to be inspected and repaired as soon as possible. Moreover, the workload is not large. Subjectively, it only takes a short time to repair the equipment and restore it to its original normal operation. The power system is a whole of power generation, transmission, distribution and consumption. Once a power accident occurs, it will affect the safe operation of the power system. The higher the voltage level of the substation, the greater the impact on the power system. At the least, it will cause chaos in the production order, affect the process quality of the product, and endanger personal safety. At worst, it will destroy the normal operation of the power generation equipment and cause significant losses to the national economy. When the power system is in operation, it often needs to be operated and maintained. Through operation and maintenance, the power system as a whole is maintained to ensure the overall operation safety of the power system. During power operation and maintenance, auxiliary devices are often needed to assist the work and help the staff. The existing way to fix the power equipment is to move the adjustment plates towards each other to complete the fixation of the power equipment. However, when fixing the power equipment in this way, the fixing speed is slow in actual work, which consumes the physical strength and energy of the operators. Therefore, a device that can quickly and automatically fix the power equipment is needed. Summary of the invention

[0028] A method for using an electric power operation and maintenance auxiliary device that is easy to fix, comprising placing the electric power equipment between the left clamping frame 17 and the right clamping frame 18 from top to bottom. During the placement process, the lower end side wall of the electric power equipment hits the inner ends of the lower plates 19 on both sides, and the inner ends of the lower plates 19 are changed from an upturned state to a horizontal state due to the impact. At this time, the electric power equipment rack is placed above the two lower plates 19; in the process of the lower plate 19 changing from an upturned state at the inner end to a horizontal state, the telescopic rod 22 pushes the outer end of the upper plate 21 upward, thereby changing the inner end of the upper plate 21 from an upturned state to a horizontal state. When the upper end of the upper plate 21 is changed to a horizontal state, it covers the upper part of the electric power equipment. Under the action of the two upper plates 21 and the two lower plates 19, the electric power equipment rack is placed above the two lower plates 19. The power equipment is fixed from the top and bottom of the power equipment respectively; according to the different heights of the power equipment, the height of the upper plate 21 and the length of the corresponding telescopic rod 22 can be adjusted in the up and down directions to adapt to the automatic clamping and fixing of power equipment of different heights; after the power equipment is fixed, when the power equipment needs to be lifted or lowered, the motor 8 is energized, and the output shaft of the motor 8 drives the screw 9 to rotate. Since the screw 9 is threadedly connected to the vertical plate 2, it moves to the right during the rotation of the screw 9. The rightward movement of the screw 9 drives the left connecting plate 10 to move to the right. The rightward movement of the left connecting plate 10 drives the first connecting rod 12 to be transformed into a vertical state. Under the cooperation of the first connecting rod 12 and the second connecting rod 13, the power equipment is driven to rise or fall.

[0029] This embodiment sets a lifting leg under the floor. When encountering an uneven ground, the height of the lifting leg can be adjusted, so that the base plate 1 can be placed stably even when placed on an uneven ground. Through the setting of the lifting component, when it is necessary to raise or lower the clamped power equipment, with the help of electric energy drive, the operator does not need to expend physical effort, and the raising or lowering of the power equipment can be completed easily and quickly, greatly improving work efficiency. Through the setting of the clamping component, when it is necessary to fix the power equipment, it is only necessary to place the power equipment inside the clamping component, and the clamping component can automatically fix the power equipment, which is easy, fast and labor-saving, and greatly reduces the work intensity of the operator.

9. The electric power operation and maintenance auxiliary device that is easy to fix according to claim 1 is characterized in that: There are four lifting legs, which are respectively arranged at the four corners of the bottom plate (1); the lifting legs comprise a lifting portion (28) fixedly connected to the lower surface of the bottom plate (1) and a rubber pad (29) fixedly arranged at the lower end of the lifting portion (28).

10. A method for using a power operation and maintenance auxiliary device that is easy to fix, characterized in that: The method comprises placing the electric equipment between the left clamping frame (17) and the right clamping frame (18) from top to bottom. During the placing process, the side wall of the lower end of the electric equipment hits the inner end of the lower plates (19) on both sides, and the inner end of the lower plates (19) changes from an upward tilted state to a horizontal state due to the impact. At this time, the electric equipment rack is placed above the two lower plates (19); during the process of the lower plates (19) changing from an upward tilted state to a horizontal state, the telescopic rod (22) pushes the outer end of the upper plate (21) upward, thereby changing the inner end of the upper plate (21) from an upward tilted state to a horizontal state. When the upper end of the upper plate (21) changes to a horizontal state, it covers the upper part of the electric equipment. Under the action of the two upper plates (21) and the two lower plates (19), the electric equipment is respectively pressed from the upper and lower sides. The electric equipment is fixed; according to the height of the electric equipment, the height of the upper plate (21) and the length of the corresponding telescopic rod (22) can be adjusted in the up and down directions to automatically clamp and fix the electric equipment of different heights; after the electric equipment is fixed, when it is necessary to lift the electric equipment, the motor (8) is energized, and the output shaft of the motor (8) drives the screw rod (9) to rotate. Since the screw rod (9) is threadedly connected to the vertical plate (2), the screw rod (9) moves to the right during the rotation of the screw rod (9). The rightward movement of the screw rod (9) drives the left connecting plate (10) to move to the right. The rightward movement of the left connecting plate (10) drives the first connecting rod (12) to be transformed into a vertical state. Under the cooperation of the first connecting rod (12) and the second connecting rod (13), the electric equipment is driven to rise or fall.
