The quick-opening anti-static light transmission device is characterized in that a lead screw (4) is fixed on a tight pulley (3), a wrenching bar (5) is fixedly arranged on a nut of the lead screw (4), the lower end of the lead screw (4) is connected with a flange cover (8) through a fixing sleeve, a flange (13) is arranged below the edge of the flange cover (8), a sealing strip (14) is arranged in a groove in the flange (13), a left rotation arm (2) and a right rotation arm (9) are respectively welded at the left end and the right end of the tight pulley (3), the lower end of the left-handed rotation arm (2) is arranged in a sleeve (1) in a sleeving manner, the lower end of the right rotation arm (9) is arranged in a locking wheel (12) in a sleeving manner, the tight pulley (12) is fixed on a fixing plate (11), and the left rotation arm (2) and the right rotation arm (9) are sleeved with bushes (10) which are connected to the flange cover (8) through fixed links (15). The quick-opening anti-static light transmission device has the characteristics of being simple to operate and high in operation efficiency.
Description
Technical field
The utility model relates to a kind of oil tank equipment to be observed and maintenance field, specifically a kind of electrostatic prevention light transmission device that starts soon.
Background technology
For daily observation and the overhaul of the equipments of oil tank need to, at airtight pressure container outside face, need to set up manhole, old-fashioned manhole cover utilizes port lid ring tightly to seal with bolt, port lid opens and closes under efficiency, inconvenient operation, along with the raising of safety specifications, the functional requirement of manhole has been observed to develop into from single uncapping and need to open fast at any time, close, and do not produced static in operation.
Utility model content
For solving the problem existing in background technology, the utility model proposes a kind of simple to operate, the fireballing electrostatic prevention light transmission device of opening soon of open and close.
The technical scheme that the utility model adopts is: a kind of electrostatic prevention light transmission device of opening soon, comprise sleeve, left-hand rotation arm, tight pulley, leading screw, blind flange, right-hand rotation arm, adapter plate, it is characterized in that: leading screw is fixed on tight pulley, on the nut of leading screw, be fixed with wrenching bar, leading screw lower end is covered by fixed cover butt flange, there is flange below, blind flange edge, in groove on flange, there is sealing band, tight pulley is left, right two ends are welded with respectively left-hand rotation arm, right-hand rotation arm, left-hand rotation arm lower end is enclosed within sleeve, right-hand rotation arm lower end is enclosed within locking wheel, locking wheel is fixed on adapter plate, on left-hand rotation arm and right-hand rotation arm, all cover has lining, lining covers by fixed link butt flange.
Effect intentionally of the present utility model is: due to the technical scheme that has adopted the utility model to adopt, this fast-open type electrostatic prevention light transmission device is arranged on oily roof manhole, when installing, cleaning at oil pipe and overhauling, only need rotating spanner bar to mention blind flange, then rotate pivoted arm and just can realize the rapidly opened and closed effect of manhole, open and close are quick, and do not produce static in operation, guarantee oil tank safety.
Accompanying drawing explanation
Fig. 1 is the utility model organigram.
In figure, 1-sleeve, 2-left-hand rotation arm, 3-tight pulley, 4-leading screw, 5-wrenching bar, 6-tightening screw, 7-adapter sleeve, 8-blind flange, 9-right-hand rotation arm, 10-lining, 11-adapter plate, 12-locking wheel, 13-flange, 14-sealing band, 15-fixed link.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of electrostatic prevention light transmission device of opening soon as shown in Figure 1, welded and installed is on tank body manhole, it is characterized in that: leading screw 4 is fixed on tight pulley 3, back-up wrench wheel on the nut of leading screw 4, spanner wheel is left, right both sides screw is threaded fixing respectively at wrenching bar 5, leading screw 4 lower ends are by fixed cover 7 butt flange lids 8, leading screw 4 lower ends are locked by tightening screw 6 in fixed cover 7, there is flange 13 blind flange 8 belows, edge, in groove on flange 13, there is sealing band 14, tight pulley 3 left sides, right two ends are welded with respectively left-hand rotation arm 2, right-hand rotation arm 9, left-hand rotation arm 2 lower ends are enclosed within sleeve 1, free to rotate, right-hand rotation arm 9 lower ends are enclosed within locking wheel 12, locking wheel 12 is fixed on adapter plate 11, on adapter plate 11, have open and closing process in the turn right slideway of arm 9, on left-hand rotation arm 2 and right-hand rotation arm 9, all overlap the lining 10 that has stable blind flange 8, lining 10 is by fixed link 15 butt flange lids 8.
When work, open and drive soon the first rotating spanner bar 5 of electrostatic prevention light transmission device, effect by leading screw 4 changes into power upwards by rotational force, leading screw 4 drives blind flange 8 to rise by fixed cover 7, at this moment open locking wheel 12, take left-hand rotation arm 2 lower ends is axle, and right-hand rotation arm 9 rotates along the slideway on adapter plate 11, can realize this and open soon opening of electrostatic prevention light transmission device.
When closing fast-open type electrostatic prevention light transmission device, first take left-hand rotation arm 2 lower ends is axle, right-hand rotation arm 9 turns to locking wheel 12 along the slideway on adapter plate 11, opposite sense rotating spanner bar 5 when opening, leading screw 4 changes into downward power by rotational force, by blind flange 8 supported flanges, locking wheel 12 locking right-hand rotation arm 9 lower ends, have realized this and have opened soon the closure of electrostatic prevention light transmission device.
