Description

Technical Field

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

[0002] Currently, the maintenance of equipment in thermal power plants is often time-consuming due to the large size of the equipment, which can lead to equipment downtime and affect the normal operation of other equipment. Therefore, the usual practice is to replace the equipment to be maintained so that the thermal power plant can quickly resume normal operation, and use cranes to move the equipment to be maintained to the maintenance area for maintenance.

[0003] Whether it is moving new equipment to the plant area for replacement or moving equipment to be repaired away from the plant area, most thermal power plant equipment is heavy. When using existing overhead cranes for transportation, the center of gravity is unstable during the lifting or transportation process, which can cause the equipment to sway or the vehicle to tip over. This damages the equipment and makes it inconvenient to replace and repair it.

[0004] Therefore, a maintenance device for thermal power plant equipment is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a maintenance device for thermal power plant equipment to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thermal power plant equipment maintenance device, comprising: a base plate,

[0007] The hook assembly, located at the top of the column on the top of the base plate, is used to lift the thermal power plant equipment that needs to be inspected onto the base plate.

[0008] The positioning component, located on the top of the substrate, is used to support and position the thermal power plant equipment that needs to be inspected, so as to prevent displacement during transportation.

[0009] The hook assembly includes a long frame with shaft holes at both ends. A first round rod and a first screw rod are respectively shafted into the holes. The first screw rod and the first round rod are mounted on a first base on their outer sides. Side plates are symmetrically arranged at the bottom of the first base, and rope components are arranged between the side plates. The end of the rope component is connected to the hook.

[0010] Preferably, a short frame is provided at the top left end of the long frame, and shaft holes are opened at both ends of the short frame. A second round rod and a second screw are spun into the shaft holes, and a second base is mounted on the outer side of the second round rod and the second screw.

[0011] Preferably, the positioning component includes a support plate located on the top of the substrate, with cylinders mounted at its four bottom corners. Multiple I-shaped plates are provided at the bottom of the support plate, and the I-shaped plates are matched with hook plate No. 1 and hook plate No. 2.

[0012] Preferably, a guide rod is provided between the first hook plate and the second hook plate, and a guide rod is also provided between the second hook plate and the push plate. The guide rod has round holes at both ends, and a rotating shaft is provided in the round holes.

[0013] Preferably, the base plate is provided with columns at the four corners of the top, the top of the columns is equipped with hook assemblies, and the top of the base plate is equipped with positioning assemblies.

[0014] Preferably, the I-shaped plate at the bottom of the support plate is divided into two parts: a horizontal array and a vertical array. The horizontal array matches the second hook plate, and the vertical array matches the first hook plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This thermal power plant equipment maintenance device, through the combined action of the hook assembly and positioning assembly, can lift the thermal power plant equipment and move it above the support plate, facilitating its transport to the device. By adjusting the displacement of the No. 1 and No. 2 bases, the stability of the device can be ensured during the handling of the thermal power plant equipment. With the cooperation of the guide rod and the No. 1 and No. 2 hook plates, the displacement of the push plate can drive the No. 2 and No. 1 hook plates to move horizontally through the guide rod, thereby reducing the area formed by the hook plates and clamping the thermal power plant equipment to prevent deviation during transport.

[0028] like Figures 1-6 As shown in the embodiment of this application, the hook assembly 2 includes a long frame 203. The long frame 203 has shaft holes at both ends, in which a first round rod 210 and a first screw rod 211 are respectively shafted. The first screw rod 211 and the first round rod 210 are mounted on a first base 201 on their outer sides. Side plates 205 are symmetrically arranged at the bottom of the first base 201, and rope members 207 are arranged between the side plates 205. The end of the rope member 207 is connected to a hook 206. Specifically, the long frame 203 is a rectangular frame with shaft holes at both ends. A first round rod 210 and a first screw rod 211 are respectively shafted in these holes. The first round rod 210 and the first screw rod 211 are mounted on their outer sides, and the first base 201 has protrusions at both ends. These protrusions match the transverse grooves on the front and rear sides of the inner wall of the long frame 203. A starting motor drives the first screw rod... 211 rotates, and during the rotation of screw 211, it drives base 201 to slide along the axis of round rod 210. Side plates 205 are symmetrically welded to the bottom of base 201, and rope components 207 are arranged between the side plates 205. Rope components 207 include: a stranded drum, a rope, and a fixed shaft. The fixed shaft is set in the shaft hole on the side plate 205, and one end of the fixed shaft is connected to the motor. A stranded drum is fixedly installed on the outer wall of the fixed shaft, and a rope is wound on the stranded drum. The end of the rope is connected to hook 206.

A thick wear-resistant rubber pad is laid on the top of the support plate 303, and four sets of cylinders are welded to its four bottom corners. The cylinders support the support plate 303 and level it. Under the action of the cylinders, the space between the bottom of the support plate 303 and the top of the substrate 1 is used to... To accommodate the movement of hook plate 301 and hook plate 302, the base plate of support plate 303 is welded with six sets of I-shaped plates 306. The I-shaped plates 306 are divided into two parts: a horizontal array and a vertical array. The horizontal array has two sets of I-shaped plates 306, which match hook plate 302, and the vertical array has four sets of I-shaped plates 306, which match hook plate 301. Hook plate 301 and hook plate 302 can slide along the I-shaped plates 306. The cooperation between hook plate 301 and hook plate 302 can position the thermal power plant equipment and prevent shaking during the transportation of the thermal power plant equipment.

[0034] The working principle of this utility model is as follows:

[0035] The thermal power plant equipment to be inspected is connected to its lugs via hook 206. The motor is started, driving rope 207 to wind up, thus lifting the equipment via hook 206. Then, another motor is started, driving screw 211 to rotate. During this rotation, base 201 slides along rod 210, moving the equipment above support plate 303. Simultaneously, a motor is started to rotate screw 209, causing base 202 to slide along rod 208, thereby adjusting the... The counterweight on the base 202 is moved horizontally to ensure the stability of the entire device during hoisting. After the thermal power plant equipment is moved above the support plate 303, the hook 206 is lowered so that it can land on the support plate 303. Then, the cylinder is started to drive the push plate 305 to move horizontally. During the horizontal movement of the push plate 305, the guide rod 304 drives the second hook plate 302 to move horizontally. During the horizontal movement of the second hook plate 302, the guide rod 304 drives the first hook plate 301 to move horizontally at the same time, thereby reducing the area formed by the hook plates. This allows the thermal power plant equipment on the support plate 303 to be positioned and avoid shaking during transportation.
