Technical Field

[0001] This utility model relates to the field of thermal power plant equipment maintenance, and in particular to a thermal power plant equipment maintenance device. Background Technology

[0002] A thermal power plant, or coal-fired power plant for short, is a factory that uses combustible materials (such as coal) as fuel to produce electricity. Its basic production process is as follows: when fuel is burned, it heats water to generate steam, converting the chemical energy of the fuel into heat energy. The steam pressure drives the turbine to rotate, converting the heat energy into mechanical energy. Then, the turbine drives the generator to rotate, converting the mechanical energy into electrical energy. Thermal power plants are equipped with a large number of electrical devices and other operating equipment, which require regular maintenance and repair.

[0003] According to the patent document with publication number CN220368376U, the patent document discloses "a maintenance device for thermal power plant equipment, which integrates a dust removal fan assembly, a screwdriver assembly, a dust removal cleaning assembly and a lighting assembly into a telescopic cylinder assembly, and uses a push rod assembly to realize the independent extension and retraction of the dust removal fan assembly, screwdriver assembly and dust removal cleaning assembly, so that maintenance personnel only need to carry this one tool to perform multiple maintenance tasks, and there will be no situation of bringing the wrong tool or forgetting to bring it. The lighting assembly is integrated into the telescopic cylinder assembly, so that maintenance personnel can use the corresponding tools for maintenance while being illuminated."

[0004] The electric arc furnace has a lot of equipment, which results in a wide variety of sizes and models of screws and bolts in each piece of equipment. Although the aforementioned device is quite functional, it only has one type of screwdriver. Therefore, when encountering screws and bolts of small or large sizes, the screwdriver in the aforementioned device is difficult to handle. Utility Model Content

[0005] The purpose of this utility model is to provide a power plant equipment maintenance device to solve the above-mentioned problems.

[0006] This utility model achieves the above objectives through the following technical solutions:

[0007] A maintenance device for thermal power plant equipment includes a frame, in which sliders are slidably connected in each of the three cavities of the frame, and also includes a maintenance structure.

[0008] The maintenance structure includes a motor, which is installed in the uppermost slider. A turntable is installed at the motor output end, and a C-shaped frame is fixed to the front end of the turntable. A double-segment screw is rotatably connected in the middle of the C-shaped frame. A traction rod is set behind the double-segment screw and is fixed to the C-shaped frame. Two sliding plates are set between the double-segment screw and the traction rod. The sliding plates are threadedly connected to the double-segment screw and slidably connected to the traction rod. A front extension rod is fixed to the front end of each of the two sliding plates. A protruding plate is set at the front end of the front extension rod. A switch button is installed on the upper end of the slider where the motor is installed. The maintenance mechanism also includes three sets of limit structures, which are respectively installed at one end of the three sliders.

[0009] Preferably, the upper end of the double-segment screw is provided with a cross handle, and the two threads of the double-segment screw have opposite directions of rotation.

[0010] Preferably, the two front extension rods are semi-circular, and the protrusions at the front ends of the two front extension rods are shaped like the tip of a flathead screwdriver.

[0011] Preferably, the limiting structure includes a double threaded head insert. The double threaded head insert is provided at the rear end of the slider. The double threaded head insert is composed of two threaded head rods and a vertical plate structure. The threaded head rods of the double threaded head insert are rotatably connected to the vertical plate structure. A rotating frame is fixed at one end of the two threaded head rods of the double threaded head insert near the vertical plate. The shape frame has multiple holes corresponding to the position of the double threaded head insert. The threaded head rods of the double threaded head insert pass through the slider and are threadedly connected to the inner wall of the shape frame.

[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] like Figures 1-5 As shown, a maintenance device for thermal power plant equipment includes a frame 1, with sliders 2 slidably connected in each of the three cavities of the frame 1, a lighting lamp installed on the front wall of the frame 1, and a maintenance structure.

[0028] The rear end of the frame 1 is provided with a frame plate 11, and multiple fixing bolts 12 are provided in the middle of the frame plate 11. The frame plate 11 is fixed to the frame 1 by the fixing bolts 12. A lifting handle 13 is fixed to the rear end of the frame plate 11. The lifting handle 13 makes it convenient for maintenance personnel to carry the device to the equipment to be maintained.

[0029] The maintenance structure includes a motor 26, which is installed in the uppermost slider 2. A turntable 27 is installed at the output end of the motor 26. A C-shaped frame 28 is fixed to the front end of the turntable 27. A double-segment screw 29 is rotatably connected to the middle of the C-shaped frame 28. A cross handle is provided at the upper end of the double-segment screw 29, and the two threads of the double-segment screw 29 have opposite directions of rotation. A traction rod 210 is provided behind the double-segment screw 29 and is fixed to the C-shaped frame 28. Two sliding plates 211 are provided between the double-segment screw 29 and the traction rod 210. The sliding plates 211 are threadedly connected to the double-segment screw 29 and slide against the traction rod 210. The sliding mechanism is connected in a dynamic manner. Each of the two sliding plates 211 has a front extension rod 212 fixed to its front end. The front end of each front extension rod 212 has a protruding plate. The two front extension rods 212 are semi-circular, and the protruding plates at their front ends are shaped like the tip of a flathead screwdriver. A switch button 213 is installed on the upper end of the slider 2 on which the motor 26 is mounted. The maintenance mechanism also includes three sets of limiting structures, each installed at one end of one of the three sliders 2. Each limiting structure includes a double-threaded head insert 21. The double-threaded head insert 21 is located near the rear end of the slider 2. The double-threaded head insert 21 is composed of two threaded head rods and a vertical plate structure. The threaded head of the threaded insert 21 is rotatably connected to its vertical plate structure. A rotating frame 22 is fixed to one end of each threaded head of the double-threaded insert 21 near the vertical plate. The shaped frame 1 has multiple holes corresponding to the position of the double-threaded insert 21. The threaded head of the double-threaded insert 21 passes through the slider 2 and is threadedly connected to the inner wall of the shaped frame 1. A fan 23 is installed at the front end of one of the lower sliders 2, and a front extension frame 24 is fixed at the front end of the other lower slider 2. A brush 25 is fixed at the front end of the front extension frame 24. When it is necessary to loosen or tighten screws or bolts in the equipment to be repaired, the uppermost slider is moved... The limiting structure on 2 is removed, allowing the slider 2, carrying the motor 26 and its output end, to extend out of the frame 1. Then, by rotating the cross handle at the upper end of the double-segment screw 29 according to the size of the screw or bolt, the sliding plate 211 is threadedly connected to the double-segment screw 29 and slidably connected to the traction rod 210. When the double-segment screw 29 rotates, the two sliding plates 211 can move in relative or opposite directions, thereby adjusting the distance between the front end protrusions of the two front extension rods 212. This makes it suitable for screws or bolts of various sizes, improving the applicability of the device.

[0030] Working principle: When the device needs to loosen or tighten screws or bolts in the equipment to be repaired, the limiting structure on the uppermost slider 2 is removed. During removal, the rotating bracket 22 on the two threaded rods of the double threaded head insert 21 needs to be rotated simultaneously, so that the two threaded rods of the double threaded head insert 21 disengage from the inner wall of the shape frame 1. Then, the double threaded head insert 21 is pulled out to remove the limiting structure, so that the slider 2, carrying the motor 26 and its output structure, can extend out of the shape frame 1. Then, the removed limiting structure is inserted into the shape frame 1 corresponding to the slider 2. Then, by rotating the cross handle at the upper end of the double-segment screw 29 according to the size of the screw or bolt, the sliding plate 211 is connected to the double-segment screw 29 by thread and the sliding plate 211 is connected to the traction rod 210 by sliding. When the double-segment screw 29 is rotated, the two sliding plates 211 can move in opposite directions, thereby adjusting the distance between the front end convex plates of the two front extension rods 212. In this way, it can be used for screws or bolts of various sizes, making the device more versatile. If the equipment needs to be cleaned, it can be cleaned by the fan 23 and the brush 25.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
