Detailed Description
Embodiments of the invention are described in detail below with reference to fig. 1-8, but the invention can be implemented in a number of different ways, which are defined and covered by the claims.
As shown in fig. 1-2, the door body guiding and locking device for the vertical rotation type flood protection door of the present embodiment is used for locking the door body when the door body is opened to a limit position, so that the door body is fixed at a required position, and is composed of a guiding and locking upright column unit 2, a hydraulic driving locking unit 3 and a hydraulic driving locking unit mounting bracket 4. The guide and locking upright post unit 2 is arranged at the bottom of the cantilever end of the door body, the hydraulic driving locking unit 3 is arranged on the hydraulic driving locking unit mounting bracket 4, and the hydraulic driving locking unit mounting bracket 4 is fixed on the ground according to the limit position of the door body after being opened. When the door body is opened to a position close to the limit opening position, the guide protruding blocks 7 on the guide and locking upright post units 2 enter the guide base 16 on the hydraulic driving locking unit 3, and the door body is decelerated by friction force and stopped at the limit opening position due to the fact that a group of friction surfaces exist on the guide protruding blocks and the guide protruding blocks, and at the moment, the hydraulic cylinders 12 in the hydraulic driving locking unit 3 drive the two groups of locking tongue units 10 and 15 to tightly hold the locking upright posts 6 and 8 on the guide and locking upright post units 2, so that the door body is locked and fixed.
As shown in fig. 3, the guide and lock column unit 2 includes a mounting base 5, lock columns 6,8, and a guide projection 7. Wherein the installation base 5 is fixed on the flood protection door 1 through bolts, and the locking upright posts 6,8 and the guide protruding blocks 7 are fixed on the installation base 5.
As shown in fig. 4, the hydraulically driven locking unit 3 comprises four mounting and limit stops 20, 21, 22, 23, four sliding guide rods 9, 17, 18, 19, two sets of latch units 10, 15, two sets of connecting uprights 11, 14, a hydraulic cylinder assembly and a guide base 16 matching the guide projections 7. The hydraulic cylinder assembly comprises a hydraulic cylinder 12 and a piston rod 13. Two sets of lock tongue units 10, 15 are mounted on four slide guides 9, 17, 18, 19 and are axially slidable along the slide guides. One group of lock tongue units 10 are hinged with the mounting holes of the hydraulic cylinder 12 through a connecting upright 11, and the other group of lock tongue units 15 are hinged with the mounting holes of the piston rod 13 through another connecting upright 14. Four sliding guide rods 9, 17, 18, 19 are mounted on four mounting and limiting baffles 20, 21, 22, 23, and the four mounting and limiting baffles 20, 21, 22, 23 are arranged according to the sliding travel of the two sets of latch units 10, 15 to restrict the two sets of latch units 10, 15 to slide in a predetermined interval.
As shown in fig. 5-7, the guide projection 7 and the guide base 16 cooperate with each other. When the door body is opened to the limit position, the guide protruding block 7 starts to enter the guide base 16, at the moment, the friction surfaces in contact with each other slow down the door body and enter a preset track due to friction until the door body stays at the preset limit position, at the moment, the control system drives the hydraulic cylinder 12 to drive the two groups of lock tongue units 10 and 15 to move from the opening position to the locking position until the two groups of lock tongue units 10 and 15 completely lock the locking upright posts 6 and 8, and thus the locking of the door body is completed, and the door body is fixed at the corresponding opening limit position.
The matching space between the guide lug 7 and the guide base 16 is specially designed, so that the guide lug 7 can smoothly enter the guide base 16 during working, and a larger friction contact surface is provided.
The deadbolt assemblies 10, 15 are in the fully unlocked position when the door body is not required to be locked. When the door body needs to be fully locked, it is in the fully locked position as shown in fig. 8.
The foregoing examples represent only a few embodiments of the present patent, which are described in more detail and detail, but are not to be construed as limiting the scope of the present patent. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
