The utility model discloses steam pocket manhole door cover board fixed knot constructs easy installation, simple structure, and has the position adjustable function, can take place the self-trimming under the deformation condition at apron or relevant adapting unit, can guarantee reliably opening and the closure of apron, the guarantee is overhauld going on smoothly with production.
Description
Technical Field
The utility model relates to a manhole door field.
Background
The manhole door is the door that is used for sealed intercommunication equipment inside and outside passageway, is a hole door that supplies personnel to pass in and out equipment inside and set up, under the general condition, drum manhole door apron is through a cantilever, with apron and fixed point connection together, the round pin hub connection is all adopted at the cantilever both ends, can't adjust apron height and position, when manhole cover is overweight or heated, when taking place to warp, then probably cause the manhole door can't open or closed, thereby influence maintenance and production.
Disclosure of Invention
The utility model aims to solve the technical problem that realize a fixed knot who has regulatory function's manhole door plant constructs.
In order to realize the purpose, the utility model discloses a technical scheme be: the utility model provides a steam pocket manhole door cover plate fixed knot constructs, the one end of U-shaped cantilever is installed in the axle bed of fixed plate for rotating the section, and the other end is installed in fixed cover for the canned paragraph, fixed cover rigid coupling is at the surface of apron, the canned paragraph is equipped with the external screw thread, fixed cover is equipped with the through-hole, the canned paragraph is fixed to be sheathe in fixed through the nut of installing on the external screw thread.
The U-shaped cantilever is arranged with an opening facing downwards, and a fastening nut and a locking nut are fixed on the external thread of the fixing section extending below the fixing sleeve.
The through hole is a waist-shaped hole, and a positioning nut is fixed on the external thread of the fixing section above the fixing sleeve.
And the upper end surface and the lower end surface of the fixed sleeve are provided with anti-skid lines.
The utility model discloses steam pocket manhole door cover board fixed knot constructs easy installation, simple structure, and has the position adjustable function, can take place the self-trimming under the deformation condition at apron or relevant adapting unit, can guarantee reliably opening and the closure of apron, the guarantee is overhauld going on smoothly with production.

the labels in the above figures are: 1. a fixing plate; 2. a cantilever; 3. a manhole cover plate; 4. fixing a sleeve; 5. fastening a nut; 6. locking the nut; 7. a waist-shaped hole.
Detailed Description
The following description of the embodiments with reference to the drawings is intended to illustrate the present invention in further detail, such as the shapes and structures of the components, the mutual positions and connections between the components, the functions and working principles of the components, the manufacturing process, and the operation and use methods, etc., so as to help those skilled in the art understand the present invention more completely, accurately and deeply.
The one end of U-shaped cantilever 2 is installed in the axle bed of fixed plate 1 for rotating the section, and fixed plate 1 generally fixes the one side at the access hole, is equipped with vertical shaft hole on the axle bed, and in the rotation section inserted the shaft hole, nut or limit structure were fixed at both ends, then the rotation section can be at the axle bed internal rotation, and the other end of cantilever 2 is installed in fixed cover 4 for the fixed section, and fixed cover 4 rigid coupling is at the surface of apron, and fixed cover 4 generally welds the central point at the apron and puts.
The canned paragraph is equipped with the external screw thread, be equipped with the through-hole on fixed cover 4, the canned paragraph is fixed cantilever 2 in fixed cover 4 through passing the through-hole, U-shaped cantilever 2 opening sets up down, be fixed with fastening nut 5 and lock nut 6 on the external screw thread of the canned paragraph that stretches out below fixed cover 4, only need one side set up the nut like this and just can hang the apron on cantilever 2, can avoid the nut not hard up through two nut fixings, guarantee the fixed reliability of apron, the height of manhole cover plate 3 just can be adjusted through the position of adjusting two nuts.
In order to further improve the regulation performance of apron, the through-hole is waist shape hole 7, the extension direction in waist shape hole 7 is parallel with the apron, be fixed with set nut on the external screw thread of the fixed section of fixed cover 4 top, fastening nut 5, lock nut 6 through set nut cooperation below then can step up fixed cover 4, make cantilever 2 fix the certain position in waist shape hole 7, realize the horizontal direction adjustment of apron, all be equipped with anti-skidding line on the upper and lower terminal surface of fixed cover 4, can guarantee the reliability of pressing from both sides tightly. The fixing nut, the fastening nut 5 and the lock nut 6 are all identical nuts, and the positions are distinguished only by names.
The present invention has been described above with reference to the accompanying drawings, and it is to be understood that the invention is not limited to the specific embodiments described above, and that the invention is not limited to the specific embodiments described above, but rather is intended to cover various insubstantial modifications of the inventive method and solution, or its application to other applications without modification.
