Description

Technical Field

[0001] The utility model belongs to the technical field of transformer substation maintenance, and in particular relates to a transformer substation patrol maintenance inspection device. Background Art

[0002] Substations are places where voltage is changed. In order to transmit the electricity generated by power plants to distant places, the voltage must be increased and converted into high voltage electricity. The voltage is then lowered as needed near the user. This work of raising and lowering voltage is completed by substations. Substations need to conduct daily inspections to determine whether there are any abnormalities. However, the existing inspections are all done manually. Equipment operation and maintenance personnel need to carry more necessary inspection tools to inspect every day. In order to effectively inspect the equipment below 3m, operation and maintenance personnel can carry ladders and take elevators such as scissor lifts to inspect equipment that is difficult to observe directly.

[0003] Compared with ladders, the use of elevators for high-altitude inspections can carry more tools, is safer and requires less physical effort. However, when using elevators in the prior art to perform high-altitude inspections in substations, there are the following two problems: 1. When the ground around the equipment to be inspected is uneven, the workbench of the elevator will also tilt after being raised, thereby reducing the stability of the device and causing a decrease in the safety of personnel operations; 2. Some substation equipment is large in size, and personnel standing on the elevator workbench cannot observe the equipment more comprehensively. In order to comply with the equipment's use regulations, the workbench needs to be lowered to a safe height before moving the elevator to a suitable position. This method reduces the inspection efficiency of maintenance personnel. Utility Model Content

[0010] In order to improve the support strength of the adjustment mechanism;

[0011] As a further improvement of the above technical solution: the inner tube body is slidably inserted into the outer tube body.

[0014] As a further improvement of the above technical solution: the controller includes a relay and a PLC module, and the controller is electrically connected to the monitoring mechanism and the oil circuit solenoid valve of the oil cylinder.

[0015] The beneficial effect of this improvement is that when the horizontal angle value fed back by the monitoring mechanism exceeds the set threshold, the controller controls the oil circuit solenoid valve of the opening and closing cylinder to make the cylinder extend and retract accordingly to adjust the horizontal angle of the lift.

[0016] In order to achieve stable movement of the workbench;

The number of the adjustment mechanisms 8 is four and they are respectively installed at the four corners of the top surface of the base 1. The adjustment mechanism 8 includes an upper ball joint 81 and a lower ball joint 82, which are respectively installed on the lift 9 and the base 1. The ball head in the upper ball joint 81 is connected to one end of the outer tube body 84, and the ball head in the lower ball joint 82 is connected to one end of the inner tube body 83. The outer tube body 84 and the inner tube body 83 are respectively connected to the piston rod and the cylinder body of the oil cylinder 85. By controlling the oil The extension and retraction of the cylinder 85, in conjunction with the use of the upper ball joint 81 and the lower ball joint 82, can adjust and change the vertical distance between the base 1 and the lift 9, thereby changing the horizontality of the lift 9 to ensure the safe use of the lift 9.

The worm pair mechanism provides self-locking protection to ensure the position stability of the workbench 105 and prevent the workbench 105 from moving due to the push and pull of external forces. ;

[0035] The working principle of the present technical solution is as follows: the towing vehicle pulls the device through the towing frame 4, so that the device moves to a suitable place of use under the support of the wheel 2, and then controls the hydraulic rod in the hydraulic support foot 3 to extend the stable support base 1, and the lift 9 rises. When the monitoring mechanism 7 detects that the horizontal angle of the bottom surface of the lift 9 exceeds the set threshold, the controller 6 controls the oil cylinder 85 in the adjustment mechanism 8 to extend and retract accordingly. When the oil cylinder 85 extends and retracts, the inner tube body 83 slides on the inner side of the outer tube body 84, and the distance between the upper ball joint 81 and the lower ball joint 82 changes. By adjusting and changing the length of the four oil cylinders 85 and cooperating with the signal feedback of the monitoring mechanism 7, the horizontal angle of the lift 9 can be adjusted to a safe range. When the operator stands on the mobile mechanism 10 and works, by controlling the direction of rotation of the drive motor 107 and the number of rotations of the output shaft, the workbench 105 can drive the operator to move in the appropriate direction, thereby effectively increasing the maintenance range; when the drive motor 107 is running, the output shaft of the drive motor 107 drives the worm 1064 to rotate, and the worm 1064 engages with the worm wheel 1063 to rotate. The rotating worm wheel 1063 drives the coaxially installed gear 1062 to rotate, and the gear 1062 then engages with the drive rack 103, so that the self-locking assembly 106 as a whole drives the workbench 105 to move, and the workbench 105 can be stably translated under the support of the support wheel 104 and the limit of the fixed plate 101.
