According to the technique proposal being provided by the utility model, a movable door panel is arranged on the doorframe, which is characterized in that a bracket is arranged on the doorframe, the door plate is hinged with a push and pull rod, another end of the push and pull rod is connected with the drive mechanism being arranged on the bracket. The utility model could improve the reliability, flexibility and tightness, overcome the defects of the time is too long when closing and causing by the insulating door which can not shut tightly, and has advantages of convenient switching and checking to the equipments.
Description
Technical field
The utility model belongs to a kind of boiler accessories, specifically a kind of device that is used for completely cutting off cold wind and hot blast on boiler.
Background technology
Isolated door is the important auxiliary equipment of boiler, and being installed on the other hot and cold air channel of heat power plant boiler needs to turn-off isolated occasion, as: coal pulverizer import air channel etc.In the prior art, owing to shortcomings such as used isolated door are unreasonable, and existence in use is not closed completely, and the shut-in time is long.
Summary of the invention
Shortcomings such as the purpose of this utility model is to design a kind of Boiler Used Coldly, hot air isolating door, to improve its reliability, flexibility and sealing property, fundamentally solves isolated before door and is not closed completely, and the shut-in time is long, the switching of convenience apparatus and stop the labour maintenance.
Technical scheme according to the utility model provides is provided with transportable door-plate on doorframe, it is characterized in that: mounting bracket on doorframe, and hinged pull bar on door-plate, the other end of this pull bar is connected with driving mechanism on being installed on support.
Pull bar is connected with slide block, and nut is set on slide block, and the screw mandrel that is connected with nut is installed on support, and the other end of screw mandrel is connected with main electric device on being installed on support.The lock shaft parallel with door-plate is installed on doorframe, is used for door-plate is pressed on eccentric wheel on the doorframe installing on the lock shaft, at the end connection fork of lock shaft, the other end of fork is connected with locking electric device on being installed on doorframe.
Two lock shafts that are parallel to each other are installed on door-plate, fork, articulated linkage between two forks are installed in the end of every lock shaft.The position that contacts with eccentric wheel on door-plate is provided with backing plate.Erection support on door-plate, pull bar utilize bearing pin and bearing hinged.The gathering sill parallel with screw mandrel is set on support, and the both sides of slide block are positioned at gathering sill.
The utility model has the advantages that: reliable operation, open and close flexibly, sealing is tight, fundamentally solved isolated before door and be not closed completely, the shortcoming that the shut-in time is long, big convenience equipment switching and stop the labour maintenance.Be widely used in each high-power station of the whole nation at present.
Description of drawings
Fig. 1 is a structure chart of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Among the figure: 1, doorframe, 2, seal receptacle, 3, eccentric wheel, 4, main lock shaft, 5, the axle that is locked, 6, slide block, 7, screw mandrel, 8, bearing housing, 9, main electric device, 10, access door, 11, seal, 12, pull bar, 13, door-plate, 14, bearing pin, 15, support, 16, connecting rod, 17, fork, 18, locking electric device, 19, backing plate, 20, bearing.
As shown in the figure: transportable door-plate 13 is set on doorframe 1, and mounting bracket 15 on doorframe 1, hinged pull bar 12 on door-plate 13, and the other end of this pull bar 12 is connected with driving mechanism on being installed on support 15.Pull bar 12 is connected with slide block 6, on slide block 6 nut is set, and the screw mandrel 7 that is connected with nut is installed on support 15, and the other end of screw mandrel 7 is connected with main electric device 9 on being installed on support 15.The lock shaft parallel with door-plate 13 is installed on doorframe 1, is used for door-plate 13 is pressed on eccentric wheel 3 on the doorframe 1 installing on the lock shaft, at the end connection fork 17 of lock shaft, the other end of fork 17 is connected with locking electric device 18 on being installed on doorframe 1.
For guaranteeing that door-plate 13 and doorframe 1 fit together fully, can the two main lock shafts that are parallel to each other 4 and the axle 5 that is locked be installed at the two ends up and down of door-plate 13, in the end of every lock shaft fork 17 is installed, in 17 articulated linkage 16 of two forks.The position that contacts with eccentric wheel 3 on door-plate 13 is provided with backing plate 19, to improve the anti-wear performance and the intensity of door-plate 13, avoids making door-plate 13 distortion occur because of the extruding of eccentric wheel 3.For ease of I﹠M, can be on door-plate 13 erection support 20, pull bar 12 utilizes bearing pin 14 and bearing 20 hinged.The gathering sill parallel with screw mandrel 7 is set on support 15, and the both sides of slide block 6 are positioned at gathering sill.
When closing, start main electric device 9, driving screw mandrel 7 by bearing housing 8 rotates, screw mandrel 7 drives slide block 6 by nut and moves in gathering sill, slide block 6 drives door-plate 13 by pull bar 12 and bearing 20 and is moved to the left, make door-plate 13 be positioned at doorframe 1, with door closure, for avoiding 1 gas leakage of door-plate 13 and doorframe, restart locking electric device 18, drive fork 17 and connecting rod 16 actions by locking electric device 18, the main lock shaft 4 and the axle 5 that is locked are rotated respectively, the eccentric wheel 3 that drives on it rotates, and by eccentric wheel 3 door-plate 13 is pressed on the doorframe 1, to guarantee to have excellent sealing performance therebetween.
