[0001] The utility model relates to the field of explosion protection, in particular to the technical field of explosion protection gradually, and specifically refers to a mobile trigger type explosion protection device. Background Technique

[0002] At present, automatic explosion protection devices in coal mines have been widely used in many coal mines in China. These devices not only improve the safety production level of coal mines, but also effectively reduce the incidence of gas explosion accidents. In practical applications, the automatic explosion protection devices show high reliability and stability, and can operate stably for a long time in harsh underground environments.

[0003] In the solution disclosed in the patent with the application number 2010206603387 and the name of automatic explosion protection device in coal mines, the explosion protection main body is fixedly connected to the fixed beam, which makes the device only capable of one-way explosion protection. In practical applications, since the specific location of gas and coal dust explosion cannot be determined, it is only possible to pre-judge the possible location of gas and coal dust explosion, and install the explosion protection device with the shock wave receiving device facing the pre-judged location. If the pre-judgment is inaccurate, the shock wave receiving device cannot receive the shock wave generated by gas and coal dust explosion.

[0004] Therefore, the patent with the application number 2021231160765 and the name of two-way opening mechanism of explosion protection device solves the above problems. Through the settings of the roller shaft, hub, hanging plate, and the limit long hole opened on the fixed beam, the sliding of the explosion protection main body on the fixed beam is realized, so as to be applicable to two-way explosion protection. However, this method has a complex structure and is not convenient for installation. Content of the Utility Model

Compared with the solution in the background technique, the structure is simple and the installation is convenient.

[0008] Preferably, the upper suspension plate and the lower suspension plate are slidably connected by a pin shaft. A long hole is formed in the upper suspension plate and / or the lower suspension plate for the pin shaft to pass through and extending along the moving direction of the flameproof main unit. The flameproof main unit moves along the radial direction of the pin shaft.

[0009] In this solution, the upper suspension plate and / or the lower suspension plate are provided with long holes for the pin shaft to penetrate through and extending along the moving direction of the flameproof main unit, which means that long holes are provided on both the upper suspension plate and the lower suspension plate, or long holes are provided on either the upper suspension plate or the lower suspension plate.

[0010] Preferably, there are two upper suspension plates, and the lower suspension plate is located between the two upper suspension plates.

[0011] In this preferred solution, by arranging two upper suspension plates, the installation position of the lower suspension plate is restricted, thus facilitating the positioning of the lower suspension plate.

[0017] The beneficial effects of the present utility model are as follows: Through the arrangement of the upper suspension plate, the lower suspension plate, and the sliding connection between the upper suspension plate and the lower suspension plate, the sliding connection between the flameproof main unit and the fixed beam is quickly realized.

[0023] To clearly illustrate the technical features of this solution, the following is an elaboration of this solution through specific implementation manners.

[0024] Refer to the attached Figures 1 - 3 , a mobile trigger type flameproof device of the present utility model includes a flameproof mainframe 1, a fixed beam 2 located above the flameproof mainframe 1. A mounting hoop is provided at the front end of the trigger mechanism of the flameproof mainframe 1, and a sliding sleeve is connected behind the mounting hoop. The sliding sleeve is sleeved on the jet pipe, and the jet pipe is fixedly connected to the flameproof mainframe 1. A front shock wave receiver 3 is provided in front of the flameproof mainframe 1, and a rear shock wave receiver 4 is provided behind the flameproof mainframe 1. The front receiving rod of the front shock wave receiver 3 is fixedly connected to the mounting hoop, and the rear receiving rod of the rear shock wave receiver 4 is fixedly connected to the flameproof mainframe 1. A limit beam 5 for restricting the forward sliding of the mounting hoop is also provided on the fixed beam 2.

[0025] The flameproof mainframe 1 is slidably connected to the fixed beam 2 through a connection structure. There are two connection structures, and the two connection structures are arranged along the moving direction of the flameproof mainframe. The connection structure includes an upper suspension plate 6 and a lower suspension plate 7 connected by a pin shaft. There are two upper suspension plates 6 and one lower suspension plate 7. The lower suspension plate 7 is located between the two upper suspension plates 6. A long hole 8 extending along the moving direction of the flameproof mainframe 1 and through which the pin shaft passes is opened on the upper suspension plate 6. A through hole for the pin shaft to penetrate is opened on the lower suspension plate 7. The pin shaft 9 sequentially passes through the long hole 8, the through hole, and the long hole 8 to connect the upper suspension plate 6 and the lower suspension plate 7. The flameproof mainframe moves along the radial direction of the pin shaft, that is, the flameproof mainframe moves in the front-rear direction, and the pin shaft extends in the left-right direction.

[0026] The upper suspension plate 6 is fixedly connected to the fixed beam 2, and the lower suspension plate 7 is fixedly connected to the flameproof mainframe 1.

[0027] Particularly, refer to the attached Figure 1 , the horizontal direction is the front-rear direction, and the direction perpendicular to the plane where the attached Figure 1 is located is the left-right direction.

[0028] When the present utility model is in use, when an explosion occurs on the front side, the explosion-proof main body 1 moves backward. When the pin shaft abuts against the rear side surface of the long hole 8, the upper suspension plate 6 restricts the lower suspension plate 7 from moving backward through the pin shaft, that is, restricts the explosion-proof main body 1 from moving backward continuously. At this time, the explosion-proof main body 1 is stationary. At this time, the loading hoop and the sliding sleeve move axially backward along the outer circumference of the air injection pipe. When moving to a certain position, the unlocking piston is unlocked, and high-pressure gas is released to trigger the explosion-proof device;

[0029] When an explosion occurs on the rear side, the pin shaft slides forward in the long hole 8, that is, the explosion-proof main body 1 moves forward. The pin shaft moves forward in the long hole. The loading hoop and the sliding sleeve cannot move due to the obstruction of the limit beam 5. At this time, the air injection pipe moves axially forward in the central hole of the sliding sleeve under the push of the explosion-proof main body 1. When moving to a certain position, the unlocking piston is unlocked, and high-pressure gas is released to trigger the explosion-proof device, thereby realizing the two-way triggering of the explosion-proof device.
