Problems solved by technology

Nowadays, most construction methods are to randomly install a steel plate at the door of the communication channel for protection. The structure is simple and the protection effect is poor; it is difficult to achieve effective protection for the communication channel; at the same time, the complex locks and mechanisms on the existing safety doors have a great impact The opening time of the safety door is determined; and then a safety door for the construction of the communication channel of the subway shield tunnel is proposed

Embodiment 1

[0022] see Figure 1-4 , a safety door for subway shield tunnel communication channel construction, comprising a wall body 1, a door frame 2, a door body 3 and a lock and an assembly, the door frame 2 is fixedly connected to the wall body 1; the door body 3 is hinged through a hinge 5 It is installed on the door frame 2, and further, the lock and the assembly are arranged between the door frame 2 and the door body 3; the relative fixing between the door frame 2 and the door body 3 is further realized through the lock and assembly. The lock and its components include a lock lever 18, an inner drive device and an outer drive device, the inner drive device is arranged on the inside of the door body 3, and the outer drive device is arranged on the outside of the door body 3; specifically, on the door frame 2 A lock hole 17 is provided, and the lock rod 18 can be interlocked with the lock hole 17; a sliding seat 19 is fixedly connected to the door body 3, and the lock rod 18 slides...

Embodiment 2

[0029] This embodiment makes the following improvements on the basis of the above-mentioned embodiment. The improvement is that the handle 6 is fixedly connected with a protective pad, and the specific material of the anti-skid pad is not limited. In this embodiment , the anti-skid pad is made of rubber material.

[0030] Further, the push plate 4 is flush with the inner surface of the door body 3, which further improves the practical use effect of the device.

[0031]The actual working principle of the device can be easily obtained from the above-mentioned embodiments: the device is divided into inner opening and outer opening during use; wherein, an electric control device is fixedly connected to the box body, and the electric control device is The electromagnet 15 is electrically connected to the device; the electromagnet 15 is driven to move by the electronic control module 21 to realize mutual locking between the telescopic block 16 and the card seat 28, and then the rack...

Abstract

The invention discloses a safety door for the construction of a communication passage of a subway shield tunnel. The device and the outer drive device, the inner drive device is arranged on the inner side of the door body, and the outer drive device is arranged on the outer side of the door body. The device is divided into inner opening and outer opening; the electromagnet is driven to move by the electronic control module to realize mutual engagement between the telescopic block and the card seat, and then the rack movement is realized by rotating the rotating shaft, and the retraction of the lock lever is further pulled. , to achieve the separation between the lock rod and the lock hole; at the same time, the universal push plate directly, the driving block is gradually inserted into the slot during the movement, under the action of the oblique opening, the roller drives the lock rod to move to achieve The retraction of the lock lever can effectively save the internal opening time and the effective protection of external opening; thus, it has a good application prospect.

Description

technical field [0001] The invention relates to the field of security protection, in particular to a safety door for the construction of a subway shield tunnel communication channel. Background technique [0002] The shield tunnel connection channel is to use one channel to open up the left and right lines of the subway tunnel, so that when there is a problem in one tunnel, you can enter from another tunnel, and then enter the place that needs rescue through the communication channel to achieve the purpose of quick rescue. . Nowadays, most of the construction methods are to randomly install a steel plate at the door of the communication channel for protection. Its simple structure has poor protection effect; it is difficult to achieve effective protection of the communication channel; at the same time, the complex locks and mechanisms on the existing security doors have a great impact. The opening time of the safety door is determined, and a safety door for the construction...
