Abstract
The utility model relates to an electric control system electric switch element of an explosion-proof diesel locomotive underground a coal mine, concretely to an intrinsic safe type combined electric control switch of a coal mine explosion-proof diesel locomotive and solving the problem that a present point-to-point control type explosion-proof switch can not meet the development requirements for a miming explosion-proof diesel locomotive. The intrinsic safe type combined electric control switch comprises an explosion-proof housing, a knob type switch, a driving lever switch, a button type switch, a key switch and a plug assembly arranged on the explosion-proof housing, and a rotating shaft penetrating the explosion-proof housing and used for connecting and fixing a locomotive steering wheel and a locomotive steering shaft; the rotating shaft is fixed to the explosion-proof housing through a bearing and a bearing pedestal; the inner of the explosion-proof housing is provided with a microprocessor; each switch on the explosion-proof housing is in connection with the microprocessor; the output terminal of the microprocessor is in connection with the plug assembly on the explosion-proof housing. The electric control system electric switch element has a simple and reasonable structure and simple wiring, can meanwhile control a plurality of paths of electrical signals and is in favor of raising the electronized degree of a mining explosion-proof diesel locomotive.
Description
Technical field
The utility model relates to the electric switch element of anti-explosion diesel engine vehicle electric control system under coal mine, and specifically a kind of coal mine explosion-proof diesel locomotive combines electric-controlled switch with intrinsic safety type.
Background technology
According to the strict demand of safety regulations in coal mine, the use of various explosion-proof electrification elements in downhole anti-explosion diesel locomotive is more and more extensive.The electric control system function of tradition mine explosion-proof diesel locomotive is fairly simple, explosion-proof component used all adopts point-to-point control mode, and a road electric signal is controlled in an explosion-proof switch contact, needs some roads electric signal to move simultaneously, just several explosion-proof switch need to be installed, take up room large; And mine explosion-proof diesel locomotive free space is limited, and due to the raising of mine explosion-proof diesel locomotive electronization degree, point-to-point control mode cannot meet the demand for development of mine explosion-proof diesel locomotive.
Summary of the invention
The utility model cannot meet the problem of mine explosion-proof diesel locomotive demand for development in order to solve existing point-to-point control mode type explosion-proof switch, provides a kind of coal mine explosion-proof diesel locomotive to combine electric-controlled switch with intrinsic safety type.
The utility model is to adopt following technical scheme to realize: coal mine explosion-proof diesel locomotive combines electric-controlled switch with intrinsic safety type, comprise explosion-proof casing, be arranged at knob switch, poke-rod type switch, push-button switch, key switch, plug-assembly on explosion-proof casing, and run through explosion-proof casing, the rotating shaft for locomotive steering wheel and locomotive steering spindle are connected and fixed; Rotating shaft is fixed by bearing, bearing pedestal and explosion-proof casing, establishes microprocessor in explosion-proof casing, and each switch on explosion-proof casing is connected with microprocessor, and the output of microprocessor is connected with the plug-assembly on explosion-proof casing.
During use, rotating shaft lower end and locomotive steering spindle are fixed, locomotive steering wheel is installed in upper end, by plug-assembly, output end of microprocessor is connected with electric equipment corresponding on locomotive; By the action of each switch on microprocessor identification explosion-proof casing, and then the driving electric equipment work corresponding with step switch function.Here it is worth emphasizing that: the seal degree of explosion-proof casing should be able to reach the degree of protection that < < safety regulations in coal mine > > requires, and in switch, all circuit are essential safe type circuit.
Compared with prior art, the utility model has changed traditional explosion-proof electrification control switch fixing arrangement on instrument desk, identical with civilian vehicle, switch is installed to below steering wheel, the driving habits that meets people, ride comfort, easy to operate, can control multipath electric signal simultaneously, and can to the switch of various modes of operation, carry out function definition according to customer requirements, realize the power supply of coal mine explosion-proof diesel locomotive electrical system, diesel engine preheating, startup, distance-light illumination, left and right turn, two sudden strain of a muscle, water spray, windscreen wiper, warm braw, loudspeaker, the anxious function such as stop.
The utility model is simple and reasonable for structure, and wiring is simple, can control multipath electric signal simultaneously, is beneficial to the electronic degree that improves mine explosion-proof diesel locomotive, meets the demand for development of mine explosion-proof diesel locomotive.
