Embodiment Construction

[0008] figure 1 In, is the structure and installation drawing of the barrier gate. The left side of the barrier gate is the left gatepost 1, and the right side is the right gatepost 5, and in the two gateposts, an upper railing rotating device is installed in one of the gateposts. For convenience of description, the doorpost installed with the upper railing rotating device is called the left doorpost below. Both the upper railing 2 and the lower railing 6 are hinged with retaining bars 3 correspondingly with connecting pins 4 at intervals. Upper railing 2, lower railing 6, and retaining bar 3 are all made of strong steel with impact resistance. The lower side of the lower railing is welded to at least two plug-in blocks 7, and what is drawn in the figure is three plug-in blocks. What the solid line draws among the figure is that the upper and lower railings of the stop gate are put down, and the gate is closed. The dotted line in the figure shows the state where the upper ...

Abstract

The invention relates to a high-strength car-stop door. The door includes an insertion block, an insertion pit, a left door post, a right door post, an upper rail, a lower rail, a stop bar and an upper rail rotating device. The stop bar is installed between the upper rail and the lower rail. One end of that upper rail is connected with a rotating device of the upper rail installed in one of the left and right door post. A low edge of that lower rail is weld and connected with a plug block. At a position correspond to that insertion block on the floor, insertion holes are arranged, and the number of insertion blocks is more than two. When the stop door is lowered, a plug block is insertedinto the pit. The upper rail, the lower rail, the stoppers and the inserts are all made of high impact resistant steel. The overall impact resistance of the barricade door is greatly improved, and the damage of the car-stop door can be reduced or avoided when an individual vehicle passes through a barrier, the repair time of the barricade door is greatly reduced, and the car-stop door can be reused quickly.

Description

technical field [0001] The invention belongs to the field of door gates, in particular to high-strength car barrier doors. Background technique [0002] Existing office, community, the car gate of garage doorway all are by upper railing, lower railing, railing interval hinge a row of retaining bar up and down. A door post is also respectively arranged on both sides of the gate, and a motor-driven upper railing rotating device is installed in one of the door posts. When the door is opened, the railing rotating device makes the upper railing rotate upwards, and the retaining strip and the lower railing are also obliquely retracted, so that the gate is convenient to open and close. The disadvantage of this kind of barrier door is that when the front end of the upper railing is lowered, it is blocked by the fork above the other gate post, but when the lower railing is lowered, there is no clamping device below, so the lower railing naturally falls and hangs in the air, unable t...
