Description

Technical Field

[0001] The utility model belongs to the technical field of maintenance platforms, in particular to a mobile maintenance platform for power plant equipment. Background Art

[0002] At present, a power plant refers to a power plant that converts some form of raw energy into electrical energy for fixed facilities or transportation, such as thermal, hydro, steam, diesel or nuclear power plants. Power plants need to inspect and repair the equipment inside the power plant at regular intervals. The inspection and repair requires the use of mobile equipment in conjunction with an inspection and repair platform to transport the power plant equipment to the corresponding maintenance process according to its problem, such as the circuit maintenance process or the sheet metal shaping process. However, most of the existing inspection and repair platforms are transported by universal wheels and frame platforms, and the transportation still requires manual pushing and moving, which is less efficient.

[0003] The publication number is CN218479491U, which is a mobile maintenance platform for power plant equipment. Through the coordination of the limit hole, connecting rod, limit block, plug hole, spiral spring, fixing tube and sleeve rod, the height of the support plate can be adjusted to meet different usage requirements and reduce the limitations of its use. However, its movement still requires manual pushing, which is inefficient. Utility Model Content

The chain conveyor belt 2 is sleeved between the outer peripheries of the two conveying wheels 1. The conveying wheels 1 are pre-buried underground. The central axis of the conveying wheels 1 is rotated, connected and fixed with external accessories.

[0031] A central shaft is provided at the center of the conveying wheel 1, and the central shaft cooperates with external accessories for rotational connection and fixation. One of the central shafts is connected to an external motor. When the motor is running, the conveying wheel 1 can rotate to achieve rotational drive.

[0032] See also Figure 4 In order to improve the conveying stability and avoid crushing, a grounding support plate 3 is provided on the bottom side of the upper surface of the chain conveyor belt 2, and one side of the top of the grounding support plate 3 is close to the chain conveyor belt 2 and fits with the chain conveyor belt 2;

[0033] A sliding portion composed of multiple balls is provided at the top portion of the grounding support plate 3 near the chain conveyor belt 2, and a grounding screw hole fixed to the ground is opened on the other side of the grounding support plate 3. A grounding bolt is passed through the grounding screw hole and fixed to the ground, so as to support and bear the load of the chain conveyor belt 2.

[0034] See also Figure 1 and Figure 2 In order to achieve the limit, the outer periphery of the chain conveyor belt 2 is connected with a plurality of limit bars 5, and the plurality of limit bars 5 correspond to each other and are distributed at equal distances. The sides of the two limit bars 5 are both designed with slopes. The slope design can facilitate loading. A bearing plate 6 is arranged between the two limit bars 5, and a rotating platform 7 is arranged above the bearing plate 6.

[0035] In order to facilitate rotation, a rotating motor 9 is embedded in the bottom center of the load-bearing plate 6, and the driving end of the rotating motor 9 is fixed to the rotating platform 7 by bolts. Inner grooves 12 are provided on both sides of the top of the rotating platform 7, and clamping plates 10 are connected to both sides of the top of the inner groove 12. A placement plate 8 is provided above the rotating platform 7;

[0036] A moving wheel 11 is provided at the bottom of the placement plate 8, and the moving wheel 11 is adapted to the inner groove 12. At the same time, the moving wheel 11 will be limited by two clamping plates 10. Both sides of the upper part of the rotating table 7 are connected with ramp plates 13. The design of the ramp plate 13 can facilitate the moving wheel 11 to move to the inner groove 12.

[0037] See also Figure 1 and Figure 2 In order to make the load-bearing plate 6 automatically come out, a step plate 4 needs to be provided on one side of the conveying wheel 1. One side of the step plate 4 is fixed to the ground. The step plate 4 is used to compensate for the outer leakage of the conveying wheel 1.

The working principles, sizes and models are irrelevant to the functions of this application, so they are not described in detail, and they are all controlled by remote control switches.

[0041] How it works

[0042] When the mobile maintenance platform for power plant equipment is needed, the power plant equipment is placed on the top of the placement plate 8, and then the straight rod 14 is inserted into the connecting hole, and the blocking cloth 15 is fixed to the outer periphery of the straight rod 14 to achieve position limiting;

[0043] By moving the moving wheel 11 at the bottom of the placement plate 8, after the load-bearing plate 6 is placed between the two corresponding limiting strips 5, the placement plate 8 is moved to the top of the rotating table 7, and the moving wheel 11 is moved to the inside of the inner groove 12 to achieve limiting;

[0044] Start the external motor to drive the conveying wheel 1 to rotate, so that the chain conveyor belt 2 rotates and conveys. After conveying to the required position, start the rotating motor 9 to drive the rotating table 7 to rotate, so that the ramp 13 faces the side of the chain conveyor belt 2, and then pull out the placement plate 8 manually or through external mechanical equipment;

[0045] After pulling out the placement plate 8, the load-bearing plate 6 continues to be transported. When it reaches the end, the edge limit strip 5 rotates to the ground. The inclined surface design of the load-bearing plate 6 will avoid getting stuck. The bottom end side of the load-bearing plate 6 is pushed to the top of the step plate 4, and the chain conveyor belt 2 continues to rotate and transport, which can automatically push out the load-bearing plate 6.
