Specific embodiment
As shown in attached drawing 1,2, the present invention includes doorframe 1, the two sides positioned at doorframe 1 and top and corresponding with doorframe 1
It door frame, the door leaf 2 being arranged on door frame by lifting power plant 3, the safety device 5 being arranged on door leaf 2 and sets
The electromagnetic screen 9 between doorframe 1 and door leaf 2 is set, it is pneumatic to be additionally provided with several groups between the door leaf 2 and doorframe 1
Pressing device 6；Lifting power plant 3 uses the structure type of electric block and pulley blocks, and electric block is fixed on door frame
Top, pulley are arranged on door leaf 2 and/or door frame, and the wirerope on electric block bypasses pulley blocks, pass through the work of electric block
Make that door leaf 2 is driven to move up and down.
Under big door closure state, gate door leaf 2 is bonded with doorframe 1, and gate pneumatic clamping system 6 compresses electromagnetic screen
9, make to realize between doorframe 1, door leaf 2 it is good electrically continuous, guarantee gate have required shield effectiveness.When gate is opened, door
Fan 2 lifting power plant 3 drag draw under move upwards, get out of the way door opening；When gate is closed, movement is opposite.When gate is opened only
The space above door body is occupied, the horizontal space of gate two sides is saved, improves space utilization rate.
The safety device 5 includes safety rope 7, counterweight 8 and anti-fall device, and the both ends of the safety rope 7 are distinguished
It is connected by anti-fall device with door leaf 2 and counterweight 8, with the weight for balancing a part of door leaf 2 is reused in, improves gate stress shape
State reduces required driving force when gate opening and closing.
As shown in Fig. 3, by taking the anti-fall device being connect with door leaf 2 as an example, anti-fall device include tension spring 503, fixture block 505 with
And the connecting plate 502 in bent, connecting plate 502 are in approximate V-arrangement, one side length is greater than another side length, in this reality
The length for applying its left plate in example is less than the length of right side plate, and the middle part of connecting plate 502 is connected by shaft 501 and the rotation of door leaf 2
It connects, there is the interconnecting piece 504 connecting for the end with safety rope in the top of shaft 501；Tension spring 503 is located at connecting plate 502
In bending, one end is fixedly connected with the left end of connecting plate 502, and the other end is fixedly connected with door leaf 2 or counterweight 8；The fixture block
505 are arranged on door frame for being clamped with the other end of connecting plate 502；Under suspended state, due to the gravity of counterweight, even
