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 the construction of a subway shield tunnel communication passage, comprising a wall 1, a door frame 2, a door body 3 and a lock and assembly, the door frame 2 is fixedly connected to the wall 1; the door body 3 is hinged through a hinge 5 Installed on the door frame 2, further, locks and components are arranged between the door frame 2 and the door body 3; the relative fixation between the door frame 2 and the door body 3 is further realized through the locks and components, specifically, the The lock and components include a lock bar 18, an inner driving device and an outer driving device, the inner driving device is arranged on the inner side of the door body 3, and the outer driving device is arranged on the outer side of the door body 3; specifically, on the door frame 2 A lock hole 17 is provided, and the lock bar 18 can be engaged with the lock hole 17; a sliding seat 19 is fixedly connected to the door body 3, and the lock bar ...

Embodiment 2

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

[0030] Furthermore, the flushness between the push plate 4 and the inner surface of the door body 3 further improves the actual use effect of the device.

[0031]The actual working principle of the device can be easily obtained from the above-mentioned embodiments: in the process of using the device, it is divided into inner opening and outer opening; wherein, an electric control device is fixedly connected to the box body, and the electric control The device is electrically connected with an electromagnet 15; the electric control module 21 drives the electromagnet 15 to move, so that the telescopic block 16 and the deck 28 are locked together, and then the rack 22 is mo...

Abstract

The invention discloses a safety door for subway shield tunnel connection channel construction. The safety door comprises a wall body, a door frame, a door body and a lock assembly, and the lock assembly is arranged between the door frame and the door body. The lock assembly comprises a lock rod, an inner side driving device and an outer side driving device, the inner side driving device is arranged on the inner side of the door body, and the outer side driving device is arranged on the outer side of the door body. The safety door is divided into an inner side opening mode and an outer side opening mode. An electric control module drives an electromagnet to move, mutual clamping between a telescopic block and a clamping base is achieved, then the rack movement is achieved by rotating a rotating shaft, the lock rod is further pulled to retract, and separation between the lock rod and a lock hole is achieved. Meanwhile, a push plate is directly pushed, a driving block is gradually inserted into a notch in the moving process, under the action of a bevel opening, a rolling wheel drives the lock rod to move, retraction of the lock rod is achieved, the internal opening time can be effectively saved, and effective protection of external opening can be achieved. Therefore, the safety door has a good application prospect.

Description

technical field [0001] The invention relates to the security field, in particular to a safety door for the construction of a communication channel of a subway shield tunnel. Background technique [0002] The shield communication channel is to use a channel to open up the left line and the right line 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 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 ...
