Abstract

The invention discloses a guiding and locking device for a vertical rotating type anti-flooding protective door. The device specifically comprises a guiding and locking stand column unit, a hydraulicdrive locking unit and a hydraulic drive locking unit mounting support, wherein the guiding and locking stand column unit is installed at the bottom of the cantilever end of a door body, the hydraulicdrive locking unit is arranged on the hydraulic drive locking unit mounting support, and the hydraulic drive locking unit mounting support is fixed on the ground according to the limit position afterthe door body is opened. When the door body is opened to the limit position, a hydraulic cylinder in the hydraulic drive locking unit drives two sets of spring bolt units to hold tightly a locking stand column on the guiding and locking stand column unit so as to complete locking of the door body, and therefore, the door body is fixed; and the device has the advantages of being simple in structure, small in occupied space, high in locking speed, large in locking torque and stable and reliable in operation.

Description

technical field

[0001] The invention relates to a door body guiding and locking device for a flood-proof protective airtight partition door used in subway and civil air defense projects, in particular to a door body guiding and locking device for a vertical-rotating anti-flooding protective door. Background technique

[0002] In current engineering applications, when the vertically rotating anti-flooding protective airtight partition doors used in subways and civil air defense projects are locked by contact and opened to the limit position, the door body needs to be decelerated and limited, and the door body needs to be opened to the limit position. Then lock it to fix the door body. The current similar devices are generally operated manually by screw jacks, which have the disadvantages of slow locking speed and incapable of automatic operation. Contents of the invention

[0003] The purpose of the present invention is to improve the deficiencies in the prior art and prov...
