Abstract

The utility model discloses a container lifting protecting device for a mining dump truck, which belongs to the technical field of engineering machinery and comprises a container bottom, a hydraulic controller, a lifting cylinder electromagnetic valve and a proximity switch. The proximity switch is disposed below the container bottom, the hydraulic controller and the lifting cylinder electromagnetic valve are arranged inside the mining dump truck, the proximity switch is electrically connected with the hydraulic controller, and the hydraulic controller is electrically connected with the lifting cylinder electromagnetic valve. The container lifting protecting device has the advantages that the container lifting protecting device is convenient in installation, the non-contact type proximity switch is adopted, the service life of the container lifting protecting device is prolonged, fault rate is reduced, and high-efficiency running of equipment is guaranteed.

Description

Mining dumper container lifting fender guard
Technical field
The utility model relates to a kind of fender guard, specifically is a kind of mining dumper container lifting fender guard, belongs to technical field of engineering machinery.
Background technology
The most rear-unloading type hoppers that adopt of quarry tipper are just controlled elevating ram (elevating ram lifting end is fixed on the container bottom through bearing pin) hopper are lifted at present, and goods is unloaded.Because in most cases; The ore deposit card does not have full visual angle surveillance system; Chaufeur can't carry out the control of appropriateness to the lifting of hopper, in most cases by virtue of experience with feel to handle elevating ram and closed and all get lifting, oil cylinder will take place like this to be crossed and lift or the situation of lifting deficiency.When the generation elevating ram is crossed act, can produce infringement to oil cylinder, reduce its work life and can cause fault, even influence safety; When lifting is not enough, can cause goods to remain on the hopper, make the actual upwards of movement of hopper reduce, reduce production efficiency.Even the method for taking travel switch to judge is arranged at present, this mechanical switch limited service life, easy et out of order under the operating mode of complicacy.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of mining dumper container lifting fender guard, can effectively address the above problem.
To achieve these goals; The technical scheme that the utility model adopts is: a kind of mining dumper container lifting fender guard, comprise container bottom surface, hydraulic control pump and elevating ram electromagnetic valve, and also comprise near switch; Be arranged on below, container bottom surface near switch; Hydraulic control pump and elevating ram electromagnetic valve are arranged on quarry tipper inside, are electrically connected with hydraulic control pump near switch, and hydraulic control pump is electrically connected with the lifting electromagnetic valve.
Principle of work: when the container bottom surface when reaching setting value near the distance of switch, send signal near switch to hydraulic control pump, hydraulic control pump receives the signal that transmits near switch, hydraulic control pump control elevating ram electromagnetic valve quits work.
The beneficial effect of the utility model is: easy for installation, adopt non-contact type approach switch, and prolonged work life, reduced fault rate, support equipment efficiently moves.
Description of drawings
Fig. 1 is the electric functional block diagram of the utility model;
Fig. 2 is the structural representation of the utility model.
Among the figure: 1, container bottom surface, 2, near switch.
The specific embodiment
To combine accompanying drawing that the utility model is described further below.
As depicted in figs. 1 and 2; A kind of mining dumper container lifting fender guard comprises container bottom surface 1, hydraulic control pump and elevating ram electromagnetic valve, also comprises near switch 2; Be arranged on 1 below, container bottom surface near switch 2; Hydraulic control pump and elevating ram electromagnetic valve are arranged on quarry tipper inside, are electrically connected with hydraulic control pump near switch 2, and hydraulic control pump is electrically connected with the lifting electromagnetic valve.
When unloading, container bottom surface 1 reaches setting value with distance near switch 2, sends signal near switch 2 to hydraulic control pump, and hydraulic control pump receives the signal that transmits near switch 2, and hydraulic control pump control elevating ram electromagnetic valve quits work.So just can avoid elevating ram to cross the situation generation of act by actv..
