The existing manhole door is opened, the door cover needs to be manually detached, the weight of the door cover is large, the workload is large during operation, and safety risks exist. And some are heavy and heavy to install on high altitude platform, because the precision is not high to make the axial depth direction have the deviation for mutual interference between the fixed of bolt and the rotation axis leads to manhole door to warp or sealed not well, and the operation needs three to four people to go on simultaneously, wastes time and energy, avoids dismantling the in-process and has crowded danger of hindering. Although some self-adjusting rotating shaft supporting devices appear in the prior art, the self-adjusting rotating shaft supporting devices are complex in structure, low in reliability, narrow in application range, incapable of preventing autorotation and incapable of ensuring sealing performance.
The utility model has the following contents:
the utility model aims at providing an adjustable rotation-preventing special-shaped double-seal manhole door.
The above purpose is realized by the following technical scheme:
an adjustable anti-rotation special-shaped double-seal manhole door comprises: the manhole door comprises a manhole door plate, a special-shaped flange and a rotating support, wherein a fine adjustment mechanism is fixed on the rotating support, the fine adjustment mechanism and the manhole door plate are fixedly used for fine adjustment of the manhole door plate in the transverse direction and the vertical direction, and the rotating support is rotatably connected with a rotating shaft.
The adjustable rotation-preventing special-shaped double-seal manhole door is characterized in that two seal grooves are formed in the special-shaped flange, and seal strips are installed in the seal grooves.
The adjustable anti-rotation special-shaped double-seal manhole door is characterized in that a multi-hole plate is fixed on the rotating support, an ear plate is fixed on the rotating shaft, and a round hole is formed in the ear plate.
Adjustable anti-rotation special-shaped double containment manhole door, fine-tuning include adjusting screw, adjustment frame, fixed cover, rotation cover and two to drawing the screw rod, adjusting screw's both ends respectively with fixation nut threaded connection, adjusting screw on be fixed with fixed cover, fixed cover and rotation cover rotatable coupling, two to drawing the screw rod, one fix on manhole door plant, another with rotation cover fixed, two to drawing the screw rod with adjustment frame threaded connection.
Has the advantages that:
1. the utility model discloses manhole door dysmorphism sets up and satisfies various special occasions and use, and the swivel mount setting does benefit to single work and avoids the station restriction, undertakes whole weight of door plant simultaneously, and fine-tuning eliminates each position and warp and guarantees accurate installation.
2. The utility model discloses multi-hole dish, otic placode, bolt cooperation are used and are prevented that during operation manhole door from closing or others mistake including the personnel from closing, prevent that the manhole door from opening or others mistake open when the personnel are not at the scene during maintenance, perhaps the inside high temperature high pressure medium that appears suddenly of system leads to direct blowout to hinder the people.
3. The utility model discloses special-shaped flange is provided with the twice seal groove, arranges in the bolt hole both sides, does benefit to under the special medium protection bolt not by blowing loss, corruption, the high reinforcing sealing performance of twice seal simultaneously. The manhole door can better meet the requirements of the site, has a simple structure and is convenient to popularize and use.
Description of the drawings:
FIG. 1 is a schematic structural diagram of the present invention;
fig. 2 is a top view of the present invention;
fig. 3 is a bottom view of the present invention;
in the figure: 1. a special-shaped flange; 2. a manhole door panel; 3. a sealing groove; 4. adjusting the frame; 5. fixing a nut; 6. adjusting the screw rod; 7. fixing a sleeve; 8. rotating the sleeve; 9. oppositely pulling the screw rod; 10. rotating the bracket; 11. a porous plate; 12. an ear plate; 13. a rotating shaft; 14. and (4) strip-shaped holes.
The specific implementation mode is as follows:
example 1:
an adjustable anti-rotation special-shaped double-seal manhole door, which comprises: the manhole door comprises a manhole door plate 2, a special-shaped flange 1 and a rotating support 10, wherein a fine adjustment mechanism is fixed on the rotating support, the fine adjustment mechanism and the manhole door plate are fixedly used for transversely and vertically fine adjustment of the manhole door plate, and the rotating support is rotatably connected with a rotating shaft 13.
Example 2:
according to embodiment 1 adjustable prevent rotation special-shaped double containment manhole door, the special-shaped flange on seted up twice seal groove 3, the seal groove in install the sealing strip, the special-shaped flange is provided with twice seal groove, arranges in bolt hole both sides, the protection bolt strengthens the leakproofness simultaneously.
Example 3:
according to embodiment 1 or 2, the adjustable anti-rotation special-shaped double-sealing manhole door comprises a rotating support, wherein a porous disc 11 is fixed on the rotating support, an ear plate 12 is fixed on the rotating support, a circular hole is formed in the ear plate, and a plurality of circular holes which are circumferentially arranged are formed in the plate surface of the porous disc.
