DETAILED DESCRIPTION

[0030] The utility model is now described in further detail with reference to the accompanying drawings.

[0031] See also Figures 1 to 6The utility model provides a technical solution: an electromagnetic pneumatic valve with a buffering function, comprising an electromagnetic pneumatic valve body 1, a front protective shell 9, a rear protective shell 8 and a buffer top 11, the outer sides of the pipeline interfaces 2 at both ends of the electromagnetic pneumatic valve body 1 are sleeved with external pipes 3, and the outer sides of the two pipeline interfaces 2 are sleeved with sealing rubber rings 4, the pipeline interface 2 and the external pipe 3 are fixed by a fixed pipe hoop 5, and a rubber pad 6 is provided on the inner side of the fixed pipe hoop 5;

[0032] The electromagnetic pneumatic valve body 1 is fixedly connected to the rear end protective shell 8 through the fixing piece 7 and the screws. The front end protective shell 9 is fixed to the front end of the rear end protective shell 8 by screws. The upper ends of the front end protective shell 9 and the rear end protective shell 8 are provided with cavities for the transmission rod 10 to pass through. Multiple transmission rods 10 are installed at the bottom of the same buffer top 11. The outside of each transmission rod 10 is sleeved with a buffer spring 12. A damping rod 13 is installed at the bottom end of the inner part of each cavity. The telescopic end of the damping rod 13 is fixedly connected to the bottom of the transmission rod 10.

[0033] An alarm component is installed inside the buffer top 11. Considering that various pneumatic platforms need to be used during tunnel construction, and the pneumatic platform needs to be composed of a pneumatic solenoid valve, a cylinder and a transmission structure, there is rockfall during tunnel construction, and the impact of the rockfall will damage the pneumatic solenoid valve, thereby affecting the normal use of the equipment. The utility model forms a barrier for buffering protection for the pneumatic solenoid valve body by setting a front end protective shell 9, a rear end protective shell 8 and a buffer top 11, which can protect the starting solenoid valve body from damage caused by the impact of rockfall in the tunnel. After the rockfall hits the buffer top 11, the buffer top 11 transmits the impact force through the transmission rod 10. At this time, the buffer spring 12 sleeved on the outside of the transmission rod 10 will absorb the impact force and release elastic potential energy. In the process of the reset spring releasing the elastic potential energy, the damping rod 13 installed at the bottom of the transmission rod 10 will inhibit the reset spring from releasing the elastic potential energy, thereby completing the buffering process. Compared with the starter valve used in tunnel construction exposed to the elements, Magnetic valve, the pneumatic solenoid valve body of the device is protected by a front protective shell 9, a rear protective shell 8 and a buffer top 11; and considering that maintenance personnel are often required to clear the fault after the impact caused by falling rocks inside the tunnel, the staff can use the alarm of the device to quickly find the fault area. When the buffer top 11 is impacted and drops, the touch-type switch 21 inside the buffer top 11 will drop as the position of the buffer top 11 drops. During the descent of the buffer top 11, the touch-type switch 21 will contact the protrusion 26 on the trigger sleeve 24, thereby triggering the alarm switch of the alarm component. At this time, the controller 15 receives the trigger instruction of the touch-type switch 21, so that the light alarm 16 flashes a dazzling light, the speaker 17 sounds an alarm, and the impact of the device can also be sent to remote personnel through the remote communication module 20, thereby realizing remote alarm. The multi-dimensional alarm function of the device provides convenience for later equipment maintenance personnel to troubleshoot.

[0034] Among them, a reserved space is reserved between the protective top and the buffer top 11 for threading an external power cord or an external wire. The reserved space is provided to facilitate the staff to connect the external power supply data cable or power cord when installing the starting solenoid valve, the cylinder and the pipeline of the transmission structure.

[0035] Among them, the alarm component includes a shell 14, a light alarm 16, a speaker 17, a processing chip 18, a backup battery module 19 and a remote communication module 20. A controller 15 is provided inside the shell 14. The controller 15 is connected to the light alarm 16, the speaker 17, the processing chip 18, the backup battery module 19 and the remote communication module 20 circuits through wires, and the controller 15 is also connected to the touch-type switch 21 circuit through wires. By setting up the alarm, it is convenient for later maintenance personnel to know the location of the device that needs maintenance in time. The light alarm 16 and the speaker 17 facilitate personnel entering the site to find the location of the damaged device. The remote communication module 20 helps remote personnel to quickly arrange personnel to enter the construction tunnel to check the fault area.

[0036] Among them, the touch-pressure switch 21 is installed at the lower end of the pillar 22, and the pillar 22 is fixedly installed inside the buffer top 11. The touch-pressure switch 21 is set to trigger the alarm. That is, after the falling stone hits the buffer top 11, the buffer top 11 descends, and the touch-pressure switch 21 at the bottom of the pillar 22 contacts the protrusion 26 at the top of the trigger sleeve 24, thereby triggering the alarm.

[0037] Among them, an L-shaped block 23 is fixed inside the rear end protective shell 8 by screws, and a stud 25 for threaded connection of the trigger sleeve 24 is fixed on the top of the L-shaped block 23, and a protrusion 26 for triggering the touch-type switch 21 is fixedly bonded to the top of the trigger sleeve 24. The material of the protrusion 26 itself is a silicone material. By setting the threaded connection mode of the trigger sleeve 24 and the stud 25, it is convenient for the user to set the trigger adjustment according to needs, that is, the greater the impact, the greater the decline of the buffer top 11, the longer the stretch between the stud 25 and the trigger sleeve 24, the smaller the impact force required for the trigger, and conversely, if the stretching distance between the trigger sleeve 24 and the stud 25 is shorter, it means that the impact force required for the trigger is greater.

[0038] The bottom of the front protective shell 9 and the rear protective shell 8 are provided with screw holes for installing the limit bolts 27, and the bottoms of the front protective shell 9 and the rear protective shell 8 are fixed to the hinge seat 28 through the limit bolts 27 and the screw holes. A sleeve rod 29 is hinged in the middle of each hinge seat 28, and a reserved cavity for pulling out the plug nail 30 is provided inside the side end of each sleeve rod 29. Each plug nail 30 is fixed by a positioning bolt 31, and the positioning bolt 31 is threadedly connected to the lower end of the sleeve rod 29. The front protective shell 9 and the rear protective shell 8 are fixed by setting the sleeve rod 29, the plug nail 30 and the positioning bolt 31. It plays the role of auxiliary support. When the device is set in the construction area, the sleeve rod 29 can be selectively installed for auxiliary support. When supporting, loosen the positioning bolt 31 to expose the plug nail 30 inside the sleeve rod 29, and tighten the positioning bolt 31 to fix it after stretching it to the required length. After fixing, directly insert the plug nail 30 into the soil of the fixed surface for auxiliary fixation. When the fixed surface of the device use area is a wall, the direction of the plug nail 30 can also be changed to align with the fixed wall position when installing the hinge seat 28. The above structure assists in improving the stability of the front protective shell 9 and the rear protective shell 8.

[0039] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
