Abstract
The utility model relates to a feed mechanism of a hydraulic drill rig, which belongs to the technical field of hydraulic drill rigs. The utility model aims to provide a feed mechanism of a hydraulic drill rig, which increases the stroke of a drill bit and has low cost. The utility model adopts a technical scheme that the feed mechanism of the hydraulic drill rig includes a feed oil cylinder, a slide block, chain wheels and a chain; the tail end of the feed oil cylinder body is fixed on the slide block; one end of a piston rod of the feed oil cylinder is fixed on a baffle; the slide block is arranged in a sliding bracket; the chain wheels and the chain are arranged on two sides of the cylinder body of the feed oil cylinder; a section of the lower part of the chain is fixed on the sliding bracket, and a section of the upper part of the chain is fixed on a mounting bracket for a rig component. Due to the adoption of the feed mechanism, the feed stroke of the rig component is two times longer than that of a feed oil cylinder; and the feed mechanism can be used in the travel-increasing aspect of the hydraulic drill rig.
Description
Technical field
The feed mechanism of the utility model hydraulic drill rig belongs to the hydraulic drill rig technical field.
Background technology
At present, most of collieries all need to install hydraulic drill rig temporarily when down hole drill, at this moment, development machine quits work and steps back under the mine, by manually prizing, push-and-pull, remove hydraulic drill rig is placed into drilling position, waste time and energy, and drill stroke is subjected to the restriction of feed cylinder stroke, very limited, increase the probing distance, must increase oil cylinder, cost is very high.
The utility model content
The utility model overcomes the deficiencies in the prior art, and technical problem to be solved has provided a kind of feed mechanism of hydraulic drill rig, has increased drill stroke, and with low cost.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: the feed mechanism of hydraulic drill rig, comprise feed cylinder, slide block, sprocket wheel and chain, the cylinder body end of feed cylinder is fixed on the slide block, the piston rod end of feed cylinder is fixed on the baffle plate, and slide block is arranged in the balladeur train, and the cylinder body both sides of feed cylinder are provided with sprocket wheel and chain, the bottom of chain is fixed on the balladeur train for one section, and one section on the top of chain is fixed on the installing rack of drill rig components.
The beneficial effect that the feed mechanism of the utility model hydraulic drill rig compared with prior art has is:
Increased the feed distance of drill rig components, cylinder body bilateral symmetry at feed cylinder is provided with pair of sprocket and chain, the bottom of chain is fixed on the balladeur train for one section, one section on the top of chain is fixed on the installing rack of drill rig components, like this, the feed distance of drill rig components becomes two times of feed cylinder stroke, and sprocket wheel chain price is not high, makes to increase the with low cost of stroke.
Description of drawings
Be described further below in conjunction with the feed mechanism of accompanying drawing the utility model hydraulic drill rig:
Fig. 1 is the structural representation of the feed mechanism of the utility model hydraulic drill rig;
Fig. 2 is the vertical view of Fig. 1;
Among the figure: 1 is that feed cylinder, 2 is that slide block, 3 is that sprocket wheel, 4 is that chain, 5 is that baffle plate, 6 is that balladeur train, 7 is that installing rack, 8 is a drill rig components.
The specific embodiment
As shown in Figure 1 and Figure 2, the feed mechanism of the utility model hydraulic drill rig, comprise feed cylinder 1, slide block 2, sprocket wheel 3 and chain 4, the cylinder body end of feed cylinder 1 is fixed on the slide block 2, the piston rod end of feed cylinder 1 is fixed on the baffle plate 5, and slide block 2 is arranged in the balladeur train 6, and the cylinder body both sides of feed cylinder 1 are provided with sprocket wheel 3 and chain 4, the bottom of chain 4 is fixed on the balladeur train 6 for one section, and one section on the top of chain 4 is fixed on the installing rack 7 of drill rig components 8.
When needing boring, hydraulic drill rig is moved to bore position, start feed cylinder 1, the cylinder body of feed cylinder 1 drives sprocket wheel 3 disposed thereon, chain 4 and slide block 2 move on balladeur train 6, because the bottom of chain 4 is fixed on the balladeur train 6, this fixed point is motionless with respect to ground, when so sprocket wheel 3 moves forward, chain 4 can dragged sprocket wheel 3 and rotate, simultaneously, chain 4 is also being dragged drill rig components 8 by installing rack 7 and is being moved, make drill rig components 8 not only along with feed cylinder 1 moves together, and LAP is also arranged with respect to feed cylinder 1, make the feed speed of drill rig components 8 increase to two times of feed cylinder 1 feed speed, thereby feed distance also increase to two times of feed cylinder 1 stroke.
