Abstract

The utility model relates to a speedy safety big lifting door, belonging to the auxiliary devices of the edifice. The door leaf of the utility model is designed with a plurality of sections. Each section of the door leaf is connected by the wire rope through a pulley and a counterweight weight. The door leaf is provided with a hand-operated elevating mechanism and a motor-operated elevating mechanism simultaneously. Each section of the door leaf is provided with a safety device. A plurality of holes are processed on both sides of a door guide track longitudinally to match with safety pins, which can guarantee that the door can be locked safely when the wire rope is broken off. The utility model has the advantages that the lifting and falling is quick and safe; the horse power of an electrical machine used in a match way is small; the cost is low, and is the ideal door of the edifice.

Description

Speedy safety big lifting door

The utility model is a kind of fast and safely large-scale overhead door, belongs to the building ancillary service.

At present, full-sized car storehouse, mine construction thing are used large-scale door, its lifting, switch required motor power are all very big, the waste electric energy, and cost is very high.

It is little that the purpose of this utility model provides a kind of required motor power, and good seal performance has the fast and safely large-scale overhead door of safe locking device.

The utility model is realized with following technical scheme: man-operated mechanism 1 is connected with hand-operated lifting steel cable 2, hand-operated lifting steel cable 2 and the more piece door leaf 7 bottommosts one joint door leaf left and right sides is connected, and every counterweight stone roller 3 cuts or polish jade with an emery wheel by counterweight that safety device 9 is connected on every joint door leaf of steel cable 4 and assembly pulley 5 and more piece door leaf 7.On the top of two side rails 13 buffer 6 is housed, on two side rails 13, automatic pilot lamp 8 is housed, on every joint door leaf of more piece door leaf 7, safety device 9 is housed, safety device 9 is that shell 17 is contained on the support plate 18, spring 15 is contained in the shell 17, safety pin 16 is contained in spring 15 and the shell 17, and the wire rope perforation 21 on the rocker 20 is connected with counterweight stone roller wire rope, and rocker 20 is contained on the support plate 18 by rotating shaft 19.Rocker 20 bottoms contact with safety pin 16.Longitudinally process some holes on two side rails 13, cooperate and to insert at any time with safety pin 16.Electronic wire rope 11 1 ends are connected with the left and right sides of the bottommost one joint door leaf of more piece door leaf 7; The other end is connected with electric up-down unit 12.Automatically the suction seal bar is contained in the bottom of the bottommost one joint door leaf of more piece door leaf 7.

The utlity model has safe in utilization, lifting rapidly, be equipped with that power of motor is little, manual and electric dual-purpose, cost are low, the distinguishing feature of good airproof performance.

Now in conjunction with the accompanying drawings the utility model is described in further detail.

Fig. 1 is the utility model front view.

Fig. 2 is that sectional view is looked on the utility model left side.
