[0002] Since the internal operation of the current drag conveyor needs to be monitored regularly, and the parts that need to be adjusted inside need to be inspected, maintained and repaired regularly, corresponding operations need to be carried out through the bottom inspection door. Therefore, the convenience and ease of operation of opening the inspection door and its own sealing performance are particularly important.
[0003] At present, most of the power plants are configured with a hinge plus a multi-plate structure. Two hinges are set on one side of the door body (2). When opening, the door body (2) rotates along the hinge rotating shaft. At the same time, in order to ensure its sealing performance, multiple nuts-fastened plates need to be set according to the size of the inspection door to press the door body (2) and the casing to ensure its sealing performance. The opening and closing processes are extremely cumbersome, which prolongs the maintenance time limit. Moreover, the plates are prone to deformation in the later use process, resulting in poor sealing and ash leakage from the machine body. Therefore, there is an urgent need to design a new type of quick-opening inspection door for the drag conveyor to solve this problem. Content of the Utility Model
[0004] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a new type of inspection door for the drag conveyor, and solve the problems put forward in the above background art.

[0006] The eccentric shaft head is welded to the eccentric shaft rod to form an eccentric connecting rod, and the opening handle is welded to the surface of the eccentric shaft rod;
[0007] The pressing component body is welded to the casing of the drag conveyor, and an internal hexagonal bolt is arranged at the upper end to adjust the pressing degree of the eccentric shaft rod to prevent over-tightening or over-loosening.
[0008] As a preferred implementation manner, a plurality of push-pull handles are welded on the surface of the door body, and a plurality of lifting handles are symmetrically welded on the surface of the door body, and the door body is conveniently lifted through the plurality of lifting handles.
[0009] As a preferred implementation manner, the sealing rubber plate is pasted on one side of the installation and mating flange with glue, the door body is buckled on the installation and mating flange, and the middle between the door body and the installation and mating flange is sealed by the rubber sealing plate.
[0010] As a preferred embodiment, a square hole is formed in the middle of the pressing assembly. A nut is arranged at one end of the pressing assembly. A screw rod passes through the nut and extends into the square hole. The eccentric shaft head is horizontally inserted into the square hole.
[0011] As a preferred embodiment, the eccentric shaft head is welded inside the eccentric shaft rod, and the center of the eccentric shaft head deviates from the center of the eccentric shaft rod.
[0012] After adopting the above technical solutions, the beneficial effects of the present utility model are as follows: By adopting a simple and easy-to-operate method of using the eccentric shaft rod to press the door body, the operation time for opening and closing is reduced, and the purpose of improving the maintenance efficiency is achieved. The middle between the door body and the installation and mating flange is sealed by a rubber sealing plate, which has good sealing performance, no dust leakage at the use site, improves the cleanliness of the site, and is not easily deformed during later use, thus improving the service life.
