Description
Technical field
The utility model relates to a kind of equipment maintenance device, is specifically a kind of manhole door.
Background technology
When inside, cigarette air channel needs repairing or adds required material, operative employee needs to open manhole door, then enter to operate, manhole door needed people for moving on one side when opening in the past, relatively effort, because manhole door needs often to open, keeps away the collision friction of doorframe and cover plate in unavoidable manhole door, affect service life, also keep away the lost situation of unavoidable cigarette air channel internal heat.
Summary of the invention
The purpose of this utility model is to provide a kind of manhole door for solving the deficiencies in the prior art, and it can open and close eaily, long service life, and can play insulation effect to cigarette air channel.
The technical scheme in the invention for solving the technical problem is: a kind of manhole door, comprises doorframe and cover plate, and described cover plate is wide at the top and narrow at the bottom, is filled with glass fibre cotton in its cavity; Described doorframe is provided with the man-hole opening matched with cover plate profile, the flanging of cover plate is fixedly installed endless elastomeric with described man-hole opening touching position, the upper end of cover plate is fixedly connected with rectangular tube, described doorframe is connected by clamping screw with one end of rectangular tube, the other end is connected by rotating shaft, and described cover plate can around axis of rotation; Described cover plate is also provided with tool box and handle.
Described endless elastomeric is preferably glass fibre, and cost is low, and can play cushioning effect, adds the service life of described cover plate.
Connecting plate on described rectangular tube and cover plate is bolted to connection, and is convenient to dismounting transport;
The beneficial effects of the utility model are: manhole door of the present utility model in use, turns on clamping screw, only need use hand propelled handle, just can rotating plate to open man-hole opening; Described cover plate being provided with the tool box for placing spanner, bringing many convenience to maintenance personal, arranging by endless elastomeric at described cover plate and door frame contact place, add the service life of manhole door.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the sectional view of the A-A of Fig. 1.In figure:
1. doorframe, 2. cover plate, 3. glass fibre cotton, 4. man-hole opening, 5. endless elastomeric, 6. rectangular tube, 7. clamping screw, 8. tool box, 9. handle, 10. connecting plate, 11. rotating shafts.
Detailed description of the invention
The technical solution of the utility model is further illustrated below by specific embodiment.
As shown in Figure 1-2: a kind of manhole door, comprise doorframe 1 and cover plate 2, described cover plate 2 is wide at the top and narrow at the bottom, is filled with glass fibre cotton 3 in its cavity; Described doorframe 1 is provided with the man-hole opening 4 matched with cover plate 2 profile, and the flanging of cover plate 2 is fixedly installed endless elastomeric 5 with described man-hole opening 4 touching position, and described endless elastomeric 5 is glass fibre, adds the service life of described cover plate 2.
The upper end of cover plate 2 is fixedly connected with rectangular tube 6, and described rectangular tube 6 can be two, and is uniformly arranged on described cover plate 2; Described cover plate 2 is also provided with tool box 8 and handle 9, and further, described rectangular tube 6 is bolted to connection with the connecting plate 10 on cover plate 2.
Described doorframe 1 is connected by clamping screw 7 with one end of rectangular tube 6, and the other end is connected by rotating shaft 11, and described cover plate 2 can rotate around rotating shaft 11; After opening clamping screw 7 by spanner, described rectangular tube 6 drives cover plate 2 to rotate around described rotating shaft 11, to open or to close described man-hole opening 4, easy to operate, eliminate potential safety hazard, described spanner can be placed in the instrument cases 8 above cover plate 2, not easily loses, and brings many convenience to maintenance personal.
Except technical characteristic described in description, be those skilled in the art known technology.
