Description

Technical Field

[0001] The present application relates to the technical field of inspection robots, and in particular to a lifting device for an inspection robot in a thermal power plant. Background Art

[0002] A thermal power plant (referred to as a thermal power plant) is a factory that uses combustibles (such as coal) as fuel to produce electricity. At present, in the important equipment room or distribution station of a thermal power plant, manual staff are usually arranged to be on duty and regularly inspect the operating status of the equipment. In the repetitive work day after day, it is easy to form inspection fatigue, which makes people numb and miss unstable signals and signs of equipment during inspection. Once equipment failure occurs, it often brings significant property losses or even personal injuries. For this reason, people consider using robots instead of manual staff to improve these problems.

[0003] However, existing inspection robots have the following shortcomings:

[0004] 1. The lack of the function to adjust the height of the equipment results in a fixed height of the inspection head, which has high limitations on the inspection and analysis of the surrounding environment;

[0005] 2. The angles of most inspection robots cannot be adjusted, resulting in blind spots in monitoring and reducing practicality;

[0006] 3. The camera housing and the robot housing are an integrated structure, which makes it inconvenient to disassemble the camera separately for maintenance and replacement.

[0007] To this end, the present application provides a lifting device for a thermal power plant inspection robot. Summary of the invention

[0008] In response to the above-mentioned problems, the present application provides a lifting device for a thermal power plant inspection robot, which is convenient for adjusting the height and angle of the inspection camera, and can also individually disassemble the inspection camera for maintenance and replacement.

[0009] To achieve the purpose of this application, this application provides the following technical solutions:

[0010] A lifting device for an inspection robot in a thermal power plant comprises an inspection base, a lifting rod is fixedly provided on the upper surface of the inspection base, and an adjustment component is provided in the lifting rod;

[0011] The adjustment assembly includes a cross groove, the cross groove is opened in the middle of the lifting rod, a screw is rotatably arranged on the inner surface of the cross groove, a cross sleeve is threadedly sleeved on the outer surface of the screw, and the cross sleeve is slidably fitted with the inner surface of the cross groove;

[0012] The ends of the cross sleeve blocks are fixed with rectangular plates, and the inner surface of the rectangular plates is fixed with inspection cameras; the inner surface of the rectangular plates is rotatably provided with a semicircular cylinder, and the side of the inspection camera is fixed with a connecting rod, and the connecting rod is detachably connected to the semicircular cylinder;

[0013] A second motor is fixedly provided on one side of the rectangular plate, and an output end of the second motor passes through the rectangular plate, and the output end of the second motor is fixedly connected to one of the semicircular cylinders.

[0014] In a possible implementation, the semicircular cylinder and the connecting rod are both provided with through holes, bolts are movably inserted into the through holes, and nuts are threadedly sleeved on the outer surfaces of the bolts.

[0015] In a possible implementation manner, a circular groove is opened inside the lifting rod, and a first motor is arranged inside the circular groove.

[0016] In a possible implementation manner, the output end of the first motor is fixedly connected to one end of the screw rod.

[0017] In a possible implementation manner, a fixed shell is fixedly provided on one side of the rectangular plate, and the second motor is arranged inside the fixed shell.

[0018] In a possible implementation, an elastic protective sleeve is movably engaged with the outer surface of the inspection camera.

[0020] In a possible implementation, four universal wheels are rotatably provided on the lower surface of the inspection base, and the four universal wheel arrays are distributed on the lower surface of the inspection base.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. In the present invention, when the height of the inspection camera needs to be adjusted, the first motor can be started to rotate its output end, thereby driving the screw to rotate, so that the cross sleeve block moves, and the inspection camera connected between the rectangular plates moves. At the same time, the second motor is started to rotate its output end to drive the semicircular cylinder to rotate, and the semicircular cylinder can rotate the inspection camera through the connecting rod. In this way, both the height of the inspection camera and the angle of the inspection camera can be adjusted.
