Abstract
A lifting alarm apparatus for a mining dump truck comprises a power supply unit, a main power switch, a parking brake pressure switch, a limit switch, a beeper and all elements are connected sequentially to form an alarm circuit, wherein an indicator is parallel-connected with the beeper; the parking brake pressure switch is disabled when the parking brake switch is enabled and enabled when the parking brake switch is disabled; the limit switch is disabled when the box is not lifted and enabled when the box is lifted. The utility model is contrived to add a plurality of electrical elements on the existing automobile circuit, which is characterized in convenient operation, easy connection and good performance, whereby the attention of the driver can not be compromised and the safe unloading and driving can be ensured.
Description
Technical field the utility model relates to a kind of dumping truck lifting warning device, particularly at the warning device of mining dump truck lifting.
The present existing mining dump truck of technical background does not all have the lifting warning device, sometimes since driver's careless and inadvertent railway carriage do not put down and put just that railway carriage scratching accident easily takes place appearance of vehicle in place, sometimes in the process of normal driving, also often occur causing the upborne phenomenon of railway carriage, thereby be prone to accidents owing to fault or other reason of lifting control system; The lifting warning device of highway dumping truck is also less, application number is 92226666.2 disclosed dumping truck autoalarms, this annunciator is as long as this annunciator sends sound and light alarm when dumping truck lifting railway carriage, lifting the bucket operation now with prompting driver vehicle, with regard to general run of thins, the working environment of dumping truck is comparatively complicated, when operation, need driver's energy to concentrate, so this scheme is sent sound and light alarm when the driver begins to operate, influence driver's attention easily, be unfavorable for safe unloading.
The summary of the invention the purpose of this utility model is to provide a kind of and is in the device that sends the sound and light alarm signal when lifting state and driver prepare to drive a vehicle at railway carriage, and be to utilize the circuit of automobile self simply to transform to form, have the dumping truck lifting warning device that uses simple, easy to connect, better performances, do not influence the driver operation attention.
The utility model is realized by following proposal, a kind of mining dump truck lifting warning device, comprise power supply, battery isolator control, the stopping brake pressure switch, limit switch, buzzer phone, indicator lamp, it is characterized in that: power supply, source switch, the stopping brake pressure switch, limit switch, the buzzer phone formation warning circuit that is linked in sequence, indicator lamp is in parallel with buzzer phone, the stopping brake pressure switch is in off-state when the vehicle parking brake switch places stop position, when placing the release position, the vehicle parking brake switch is in closure state, limit switch is at railway carriage during not by lifting, be in off-state, be in closure state during by lifting at railway carriage.
Because the utility model is to increase electric elements such as stopping brake pressure switch, limit switch, buzzer phone, indicator lamp on the basis of existing automobile circuit, so have the advantages that to use simple, easy to connect, better performances, do not influence the driver operation attention, help the safety unloading and drive a vehicle.
The circuit diagram of a kind of mining dump truck lifting of description of drawings warning device
The specific embodiment is described the utility model in more detail below in conjunction with accompanying drawing:
As shown in drawings, the utility model is reequiped on the TEREX3307 mining dump truck of the heavy vapour production in the north, by the warning circuit that power supply 1, source switch 2, stopping brake pressure switch 3, limit switch 4, buzzer phone 6 are linked in sequence and constitute, described power supply 1 is the mining dump truck its own power source; Source switch 2 is a mining dump truck its own power source main supply switch; The parking brake switch UNICOM of stopping brake pressure switch 3 and mining dump truck, when the vehicle parking brake switch places stop position, stopping brake pressure switch 3 no air pressure, so be in off-state, when the vehicle parking brake switch placed the release position, stopping brake pressure switch 3 was in closure state under the effect of air pressure; Limit switch 4 is loaded on mining dump truck and the crossbeam that railway carriage links to each other, when railway carriage is picked up when leaving crossbeam, limit switch 4 is in closure state under the effect of self elastic force, when the whole return of railway carriage, the contact of limit switch 4 is pushed down by railway carriage, and limit switch 4 is in off-state; Buzzer phone 6 and indicator lamp 5 adopt the general-duty element; Indicator lamp 5 is connected in parallel in the warning circuit with buzzer phone 6.
When dumping truck is in the stopping brake state, during the lifting railway carriage, stopping brake pressure switch 3 is in off-state, and limit switch 4 is in closure state, and this moment, warning circuit was obstructed, and indicator lamp 5 and buzzer phone 6 do not send sound and light alarm.
When all not put down by the railway carriage of lifting when promptly not getting back on the crossbeam, if the driver discharges parking brake switch starting vehicle, stopping brake pressure switch 3 is in closure state under the effect of air pressure, and put owing to railway carriage does not also all put down this moment, limit switch 4 also is in closure state, so warning circuit is connected, 6 of indicator lamp 5 and buzzer phones send sound and light alarm, and the prompting driver is not because railway carriage is put into the position, can not drive a vehicle this moment, to avoid taking place the scratching accident; After by the whole returns of the railway carriage of lifting, limit switch 4 is disconnected, and this moment, sound light alarming circuit disconnected, and expression driver's this moment can start vehicle normal row car.
At ordinary times, the work under bad environment of mine truck, in the process of normal driving, also often occur causing the upborne phenomenon of railway carriage owing to fault or other reason of lifting control system, thereby be prone to accidents, warning device of the present utility model can send sound and light alarm at this moment at once, prompting driver railway carriage is picked up, please stop driving, to avoid accident.
Because sound and light alarm appears under the situation that may jeopardize traffic safety, and sound and light alarm does not appear in normal lifting unloading, so can not influence driver's attention, helps safe driving and unloading.
At general discharging vehicle, only need to change stopping brake pressure switch 3 into travel switch and link to each other to realize the purpose of this utility model with holding brake device.
