Abstract
The utility model discloses a novel excavating loader with a rock drill, which comprises a hydraulic controller (1), a stand (3) and the rock drill (2) which is movably installed on the stand in a matching way, wherein the rock drill comprises a hydraulic loop (4), an oil path switching valve (8) is arranged between the hydraulic loop and the hydraulic controller and is provided with a pressure oil inlet (11), an interface A (10) and an interface B (9), the interface A (10) and the interface B (9) are respectively connected with the rock drill and the hydraulic controller, a high pressure accumulator (6) is connected to a pipeline of the pressure oil inlet (11), and a lower pressure accumulator (5) is connected to a pipeline of the oil return end (7). With the adoption of the novel excavating loader, the rock drill and the excavating loader can be alternately used; and the novel excavating loader with the rock drill has the advantages of high construction efficiency, flexible and convenience in operation, low failure rate, long service life, low labor intensity and the like and can be widely used for production work of marbles, granites, metal minerals, coal minerals and nonmetallic minerals.
Description
Technical field
The utility model relates to crawler belt, tire, the rail wheel type loader-digger of various models, refers more particularly to the crawler belt and the rail wheel type loader-digger that use in the mine.
Background technology
The utility model relates to crawler belt, tire, the rail wheel type loader-digger of various models, refers more particularly to the crawler belt and the rail wheel type loader-digger that use in the mine.
The utility model content
At the problem that exists in the loader-digger use in the prior art, the utility model provides a kind of can carry hammer drill and interchangeable novel loader-digger at random.
The technical scheme that the technical problems to be solved in the utility model is taked is: the described cutter that has
The novel loader-digger of rock machine comprises hydraulic controller and frame, described hammer drill active mounting is on frame, described hammer drill comprises hydraulic circuit, be provided with the oil circuit transfer valve between described hydraulic circuit and the hydraulic controller, described oil circuit transfer valve has a pressure oil import and has an A interface that links to each other with hammer drill and the B interface that links to each other with hydraulic controller respectively, on the pipeline of pressure oil import, be connected with high pressure accumulator, on the pipeline of oil revolving end, be connected with low pressure accumulator.
When loader-digger work and hammer drill when not working, the pressure oil import is connected and is also switched to B interface, this moment the A interface close, B interface cut-in pressure oil, pressure oil enters the hydraulic controller of loader-digger, makes loader-digger work; When loader-digger quits work and hammer drill when starting working, the pressure oil import is connected and is also switched to the A interface, this moment B interface close, A interface cut-in pressure oil, pressure oil enters the hydraulic circuit of hammer drill, makes hammer drill work; When the pressure oil import was closed, A interface and B interface were all closed, and this moment, loader-digger and hammer drill quit work.
The novel loader-digger that has hammer drill described in the utility model can not only make that hammer drill and loader-digger are used alternatingly, the efficiency of construction height, and flexible and convenient operation, advantage such as fault rate is low, long service life, labour intensity are low.It can be widely used in the exploitation work of marble, granite, metallic ore, colliery and nonmetallic ore.
Description of drawings
Fig. 1 is a structural representation of the present utility model,
Fig. 2 is a hydraulic pressure connection diagram of the present utility model.
Hydraulic controller 2, hammer drill 3, frame 4, hydraulic circuit 5, low pressure accumulator 6, high pressure accumulator 7, oil revolving end 8, oil circuit transfer valve 9, B interface 10, A interface 11, pressure oil import in the drawings, 1.
The specific embodiment
Shown in Figure 1, hammer drill 2 active mountings at the rear portion of frame 3, are connected the existing hydraulic circuit 4 of hammer drill with pipeline on the existing hydraulic controller 1 of loader-digger, the hydraulic schematic diagram of hammer drill work is as shown in Figure 2.
The described novel loader-digger that has hammer drill comprises hydraulic controller 1, frame 3 and the active mounting hammer drill 2 on frame, described hammer drill comprises hydraulic circuit 4, be provided with oil circuit transfer valve 8 between hydraulic circuit and the hydraulic controller, described oil circuit transfer valve has a pressure oil import 11 and has an A interface 10 that links to each other with hammer drill and the B interface 9 that links to each other with hydraulic controller respectively, on the pipeline of pressure oil import 11, be connected with high pressure accumulator 6, be connected with low pressure accumulator 5 on the pipeline of oil revolving end 7, oil return pipe one end links to each other with oil revolving end 7, the other end links to each other with fuel tank.
The super pressure that the main effect of the low pressure in hydraulic schematic diagram shown in Figure 2, high pressure accumulator produces when being absorption work is with the protection hydraulic system; The pressure oil import connects the main oil pump of loader-digger; The fuel tank of oil return termination loader-digger; What represent in the chain-dotted line among Fig. 2 is the annexation of Hydraulic Elements in the existing hydraulic circuit of hammer drill.
In practical operation, when using hammer drill, if loader-digger produces action, to operating personnel and equipment is and dangerous.Therefore must design the oil circuit transfer valve in hydraulic circuit, when B interface 9 cut-in pressures oil, loader-digger can be operated, and hammer drill is not supplied with hydraulic oil, can't move.When A interface 10 cut-in pressures oil, the operating grip of loader-digger is failure to actuate, and machine also can't move, because there is not pressure oil to enter, this moment, pressure oil entered the hammer drill operation part, and hammer drill can be worked.
Concrete operations are as follows: in the time of loader-digger work, hammer drill hangs over the frame rear portion of loader-digger, and hammer drill is not worked.After loader-digger work is finished, take off hammer drill, hammer drill has oil pipe to link to each other with loader-digger, oil pipe reasonably must be placed on the ground, switches the oil circuit valve A interface is connected, and operates the hand push button boring blast hole drilling on the hammer drill then.After having beaten borehole, hammer drill is reinstalled loader-digger, switch the oil circuit valve B interface is connected, the position of safety when retreating loader-digger to explosion.After finishing Deng explosion, ore is taken off and get, carried to the loader-digger that advances.By that analogy, cycling.
