Abstract
The utility model discloses a lift protecting device for a mining dumper hopper and belongs to the technical field of construction machinery. The lift protecting device for the mining dumper hopper comprises a hopper, a hydraulic controller and a lifting electromagnetic valve, and further comprises a travel switch, wherein the travel switch is arranged at the tail part of the hopper, the hydraulic controller and the lifting electromagnetic valve are arranged inside the mining dump truck, the travel switch is electrically connected with the hydraulic controller, and the hydraulic controller is electrically connected with the lifting electromagnetic valve. The utility model has the benefits of simplicity in operation and convenience in use, and can automatically stop when reaching an assigned position.
Description
Technical field
The utility model relates to a kind of fender guard, specifically is a kind of quarry tipper hopper 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 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.
Summary of the invention
To the problem that above-mentioned prior art exists, the utility model provides a kind of quarry tipper hopper 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 quarry tipper hopper lifting fender guard, comprise hopper, hydraulic control pump and lifting electromagnetic valve, and also comprise travel switch; Travel switch is arranged on the afterbody of hopper; Hydraulic control pump and lifting electromagnetic valve are arranged on quarry tipper inside, and travel switch is electrically connected with hydraulic control pump, and hydraulic control pump is electrically connected with the lifting electromagnetic valve.
Principle of work: when hydraulic control pump receives the signal that travel switch transmits, hydraulic control pump control lifting electromagnetic valve quits work.
The beneficial effect of the utility model is: simple to operate, easy to use, can stop automatically behind the arrival assigned address.
Description of drawings
Fig. 1 is the schematic block circuit diagram of the utility model;
Fig. 2 is the position view of the utility model.
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 quarry tipper hopper lifting fender guard comprises hopper 1, hydraulic control pump and lifting electromagnetic valve, also comprises travel switch 2; Travel switch 2 is arranged on the afterbody of hopper 1; Hydraulic control pump and lifting electromagnetic valve are arranged on quarry tipper inside, and travel switch 2 is electrically connected with hydraulic control pump, and hydraulic control pump is electrically connected with the lifting electromagnetic valve.
During use; When hopper 1 reached the angle of setting, travel switch 2 sent signal and passes to hydraulic control pump, and hydraulic control pump control lifting electromagnetic valve quits work; So just can protect the safe handling of hopper 1 effectively, can goods in the hopper 1 all be poured out simultaneously.
