Preferably, the flameproof box is further internally provided with a wiring terminal, the safety belt buckle switch and the seat film pressure switch are connected to the control module through the wiring terminal, and the control module is connected with the alarm prompt module.
Preferably, the control module is a solid state relay module.
Preferably, the power supply adopts an intrinsic safety power supply.
Preferably, the alarm prompt module is a pouring and intrinsic safety type audible and visual alarm.
Preferably, the solid-state relay module in the explosion-proof box is connected with a battery box through an explosion-proof cable, and the battery box adopts an explosion-proof battery box.
Compared with the prior art, the beneficial effects of the utility model are embodied in that: the anti-explosion rubber-tyred vehicle has the advantages of simple, independent and compact structure and convenient spatial arrangement, meets the anti-explosion requirement through the cooperation of all the parts, can prompt a driver to fasten a safety belt under the condition that the driver does not fasten the safety belt, and provides safety guarantee for the running of the coal mine trackless rubber-tyred vehicle.
Drawings
FIG. 1 is a structural diagram of an unbuckled reminding device of an explosion-proof safety belt of the utility model;
fig. 2 is a schematic diagram of the reminder for the unbuckled explosion-proof safety belt.
Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Example one
As shown in fig. 1 and 2, the explosion-proof safety belt unbuckled reminding device for the coal mine underground trackless rubber-tyred vehicle comprises a safety belt buckle switch 3 installed on a safety belt buckle and a seat film pressure switch 2 installed below a seat, wherein the safety belt buckle switch 3 and the seat film pressure switch 2 are respectively connected to an explosion-proof box 4 through an explosion-proof cable 8, a control module 5 is arranged in the explosion-proof box 4, the control module 5 is connected with a power supply 7, and the explosion-proof box 4 is connected with an alarm reminding module 9 through the explosion-proof cable.
Still be equipped with binding post 6 in the flame proof case 4, safety belt buckle switch 3 with seat film pressure switch 2 through binding post 6 connect in control module 5, control module 5 passes through explosion-proof cable connection warning prompt module 9.
Specifically, the power supply 7 adopts an intrinsic safety power supply, and the power supply 7 provides electric energy for the control module 5, the safety belt buckle switch 3 and the seat film pressure switch 2; the intrinsic safety power supply is an intrinsic safety power supply, belongs to explosion-proof electrical equipment for explosive gas environment, and has clear requirements in the mandatory national standard GB 3836. Either direct or alternating current, which in extreme cases does not ignite explosive gases by the discharge energy.
The control module 5 is a solid-state relay module which outputs audible and visual alarm control signals to drive the alarm prompting module.
The alarm prompt module 9 is a pouring and intrinsic safety type audible and visual alarm, and can send out a prompt tone for asking to fasten a safety belt and an LED flashing signal after receiving a signal, and meanwhile, the underground explosion-proof requirement can be met.
The solid-state relay module in the explosion-proof box 4 is connected with the battery box 1 through an explosion-proof cable, the battery box 1 adopts an explosion-proof battery box, and the battery box 1 provides electric energy for the alarm prompt module 9 under the control of the solid-state relay module.
