Description

Technical Field

[0001] This application relates to an inspection door cover for equipment, and particularly to a door cover boosting structure. Background Art

[0002] The multi-piece design of the inspection door cover causes waste of equipment resources layout and space; too much manpower is required to open the locking mechanism before opening, which is time-consuming and laborious.

[0003] Now in many working conditions, due to equipment layout requirements, large inspection door covers need to be set on the equipment; often, there are not enough resources to open them, but due to the large size of the door cover, there are also many safety hazards in manual opening. Summary of the Utility Model

[0004] The purpose of the present utility model is to provide a door cover boosting structure, which is provided with a mechanical boosting device to save manpower and material resources.

[0005] To achieve the above purpose, the present utility model provides the following technical solutions.

[0006] The embodiment of the present application discloses a door cover boosting structure, including a top steel plate of the equipment. Two windows arranged side by side are formed on the top steel plate of the equipment. A door cover is respectively hinged on one side of the two windows facing away from each other. The door cover closes the corresponding window. An air spring is respectively arranged on the same side of the two door covers. The two ends of the air spring are respectively hinged to the door cover and the top steel plate of the equipment.

[0007] Preferably, in the above door cover boosting structure, a bolt penetrates through the top steel plate of the equipment between the two door covers. A cover plate penetrates through the bolt. A handwheel is arranged above the cover plate. The handwheel is threadedly connected to the bolt. The cover plate abuts against the top surfaces of the two door covers.

[0008] Preferably, in the above door cover boosting structure, the bolt is welded to the top steel plate of the equipment.

[0009] Preferably, in the above door cover boosting structure, a bending is formed downward on one side of the two door covers facing each other.

[0010] Preferably, in the above door cover boosting structure, 2 handwheels are arranged.

[0011] Compared with the prior art, the advantages of the present utility model are as follows:

[0012] 1. The size and weight of the equipment door cover are large; often, it cannot be opened by only 1 - 2 people. The air spring can be used in cooperation to save manpower and material resources;

[0013] 2. After the gas spring is opened, it plays a supporting role. After being matched with corresponding components, it can be locked by a program, improving the safety factor during the use after the door cover is opened.

[0014] 3. For explosion - prone areas, if a motor - driven device is adopted, additional safety facilities need to be added, resulting in huge additional costs.

[0015] 4. Compared with other pneumatic auxiliary devices such as cylinders, the gas spring has the great advantage of occupying less space. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will combine the drawings in the embodiments of the present utility model to describe the technical solutions in the embodiments of the present utility model in detail. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0021] Combined with Figures 1-3As shown in the figure, the door cover assist structure 100 includes a top steel plate 101 of the device. Two windows 102 arranged side by side are formed on the top steel plate 101 of the device. On the opposite sides of the two windows 102, a door cover 103 is respectively hinged. The door cover 103 closes the corresponding window 102. On the same side of the two door covers 103, a gas spring 104 is respectively arranged. The two ends of the gas spring 104 are respectively hinged to the door cover 103 and the top steel plate 101 of the device. A bolt 105 is passed through the top steel plate 101 between the two door covers 103. A cover plate 106 is passed through the bolt 105. A handwheel 107 is arranged above the cover plate 106. The handwheel 107 is threadedly connected to the bolt 105. The cover plate 106 abuts against the top surfaces of the two door covers 103. The bolt 105 is welded to the top steel plate 101 of the device. On the opposite sides of the two door covers 103, a downward bend is formed. There are 2 handwheels 107 arranged.

[0022] In this embodiment, the structure is as follows:

[0023] 1) The top steel plate of the device;

[0024] 2) The hinge of the maintenance door cover: a mechanical device used to connect the door cover and the top steel plate and allow relative rotation between the two;

[0025] 3) The body of the maintenance door cover: the entrance and exit for personnel installation and material replacement;
