Description
Technical field
This utility model relates to a kind of elevating mechanism, particularly relates to the elevating mechanism of a kind of lift airtight blast door.
Background technology
The sealing of closed guard gate of the prior art and locking structure relative complex, cause the inconvenience of operation, and properties is unoutstanding.
Chinese patent 201310656881.8, open a kind of automatic shield door, it includes doorframe, door body, and the coupling part of doorframe and door body, it is characterized in that: described door body is provided with metallic plate, door body surrounding is embedded with a close-packed arrays all-in-one-piece metal spring comb shape sheet, and is connected with doorframe, the inner surface of doorframe surrounding is embedded with the metallic plate of one, described in door body side equipped with detection device, driver is installed in doorframe upper end, and detection device is connected with driver.This structure relative complex, and result of use is general.
Utility model content
This utility model mainly solves the deficiencies in the prior art, it is provided that a kind of compact conformation, easy to operate, the elevating mechanism of a kind of lift airtight blast door that braking ability is strong.
Above-mentioned technical problem of the present utility model is addressed mainly by following technical proposals:
A kind of elevating mechanism of lift airtight blast door, including ground and doorframe, described ground is provided with the groove of inner concavity, and the bottom of described doorframe is placed in groove, being provided with door leaf in described doorframe, described door leaf and doorframe are by vertical shaft assembly phase bracing displacement；
Described vertical shaft assembly includes vertical shaft, diverter and worm reducer, the upper end of described doorframe is provided with hinge page seat, the lower end of described doorframe is provided with lower hinge page seat, the upper end of described vertical shaft and upper hinge page seat rotate location, the lower end of described vertical shaft and lower hinge page seat rotate location, the top and bottom of described door leaf are respectively through rotating hinge and vertical shaft phase activity orientation, the bottom of described vertical shaft be provided with ground rotate location screw jack, it is fixedly connected by shaft coupling between described diverter and screw jack, described diverter is fixedly connected by connecting rod and worm reducer, described worm reducer is provided with rotation hands wheel, described screw jack drives vertical shaft to carry out upper and lower displacement；
Location is supported mutually by loading arm between described door leaf with vertical shaft.
As preferably, between described loading arm and vertical shaft, rotate and rotate respectively through bearing between hinge and vertical shaft.
Door leaf lifting order: rotate handwheel, the input of transmission worm gear case, output shaft, connecting rod, diverter input, output shaft by " liter " direction, rotated by lower link shaft coupling, screw jack input helical teeth axle, drive screw rod rotates, promote jacking sleeve, so that the vertical shaft connecting door leaf rises 125 millimeters completes door leaf lifting requirement.Diverter power shaft, its output shaft connects screw jack and moves upward, thus the vertical shaft connecting door leaf rises 125 millimeters.Complete door leaf and promote requirement.
Door leaf descending order: rotate handwheel by " dropping " direction, door leaf simultaneous axle declines 125 millimeters, completes door leaf decline requirement.
It is assemblied in the roller fine setting vertical shaft vertical precision on upper and lower hinge page seat, makes door leaf lifting, flat turn more flexible.
Therefore, the elevating mechanism of a kind of lift airtight blast door of the present utility model, compact conformation, serviceability is good, easy to operate.
