Abstract
The invention provides a hydraulic impact hammer device added on a hard rock heading machine and a hard rock heading method and belongs to the technical field of hard rock heading. The hydraulic impact hammer device added on the hard rock heading machine and the hard rock heading method can be suitable for heading operation of large-section full hard rock and half rock roadway, have small structural strength on a roadway surrounding rock layer and can further improve heading and cutting efficiency. The hydraulic impact hammer device comprises a hammer, a hammer handle, a hydraulic cylinder and a connecting seat, wherein the hammer is fixedly connected with the hammer handle, the hammer handle is connected with one end of the hydraulic cylinder, and the other end of the hydraulic cylinder is connected with the connecting seat. The hard rock heading method used by being matched with the hydraulic impact hammer device and a hobbing cutter type cutting head of the hard rock heading machine comprises the steps of utilizing the hobbing cutter type cutting head to cut a rock body to form a cutting groove; enabling the hobbing cutter type cutting head to retreat back to the position away from the rock body after the groove cutting is finished; starting the hydraulic impact hammer device; enabling the hammer of the hydraulic impact hammer device to be close to the edge of cutting groove till the hydraulic impact hammer device touches the rock body, and using the hammer to hammer the rock body till the rock body breaks.
Description
Technical field
The invention belongs to hard rock driving technology field, particularly relate to a kind of hydraulic impact hammer device and hard rock driving method that is installed in hard rock mole.
Background technology
At present, in the face of the fully hard rock of big section and half rock gangway road, driving mode mostly Bian is adopted operation with big gun.It is a not only arduous but also dangerous job that but big gun is adopted operation, and not only production efficiency is lower, and operator's labour intensity is very big.Often after big gun is adopted operation, can cause certain destruction to roadway surrounding rock layer De Jie Ju intensity.And existing hard rock mole mainly is to be applicable to medium-hard coal petrography and alternate heading, and is not suitable for the road operation of fully hard rock gangway; Hard rock mole is in tunneling process simultaneously, and when particularly running into the high rigidity rock mass, the vibration of hard rock mole body can strengthen, and lateral sliding also can increase thereupon, has had a strong impact on the efficient of excavation operation, has reduced the reliability of hard rock mole.
Summary of the invention
Problem at the prior art existence, the invention provides a kind of hydraulic impact hammer device and hard rock driving method that is installed in hard rock mole, the present invention is applicable to the excavation operation in the big fully hard rock of section and half rock gangway road, very little to roadway surrounding rock layer De Jie Ju intensity effect, not only improve the cut efficient of hard rock mole, and guaranteed the reliability of hard rock mole.
To achieve these goals, the present invention adopts following technical scheme: a kind of hydraulic impact hammer device that is installed in hard rock mole, comprise tup, hammer handle, hydraulic cylinder and Connection Block, described tup and hammer handle Joint, hammer handle is connected with an end of hydraulic cylinder, and the other end of described hydraulic cylinder is connected with Connection Block.
Adopt described a kind of hard rock driving method that is installed in the hydraulic impact hammer device of hard rock mole, the hob type cutterhead of described hydraulic impact hammer device and hard rock mole is used, and may further comprise the steps:
Step 1: utilize the hob type cutterhead that rock mass is carried out cut, rock mass is formed cut groove;
Step 2: after cutting the groove cut and finishing, make the hob type cutterhead return to position away from rock mass;
Step 3: the hydraulic impact hammer device starts;
Step 4: the tup that makes the hydraulic impact hammer device is near the edge that cuts groove, and up to the touching rock mass, tup begins the hammering rock mass, falls until rock mass is broken.
Beneficial effect of the present invention:
Hard rock mole and the hard rock driving method thereof of hydraulic impact hammer device of the present invention are installed, overcome existing hard rock mole weak point technically, excavation operation applicable to the big fully hard rock of section and half rock gangway road, adopting operation with big gun compares, greatly reduce the danger of excavation operation, reduced operator's labour intensity, not only very little to roadway surrounding rock layer De Jie Ju intensity effect, and improved the cut efficient of hard rock mole, also guaranteed the reliability of hard rock mole.

Fig. 2 is the hard rock mole structural representation that hydraulic impact hammer device of the present invention is installed;
Fig. 3 is the vertical view of Fig. 2;
Among the figure, 1-tup, 2-hammer handle, 3-hydraulic cylinder, 4-Connection Block, 5-hob type cutterhead, 6-cutting arm, 7-adjusted cylinder, 8-down regulate cylinder.
The specific embodiment
The present invention is described in further detail below in conjunction with the drawings and specific embodiments.
As shown in Figure 1, a kind of hydraulic impact hammer device that is installed in hard rock mole comprises tup 1, hammer handle 2, hydraulic cylinder 3 and Connection Block 4, described tup 1 and hammer handle 2 Joints, hammer handle 2 is connected with an end of hydraulic cylinder 3, and the other end of described hydraulic cylinder 3 is connected with Connection Block 4.
Shown in Fig. 2,3, before the use, at first hydraulic impact hammer device of the present invention is packed in the both sides of hard rock mole cutting units by Connection Block 4, the hard rock mole cutting units adopts the hob type cutterhead.The control end of described hydraulic cylinder 3 is arranged in the control room of hard rock mole.During in the face of the fully hard rock of big section and half rock gangway road, in the hard rock mole tunneling process, if utilize hob type cutterhead 5 to carry out headwork this moment separately, not only drivage efficiency can reduce greatly, the reliability of hard rock mole is reduced, just need being used of hydraulic impact hammer device and hob type cutterhead 5 this moment so, to continue to finish the headwork of back.
Adopt described a kind of hard rock driving method that is installed in the hydraulic impact hammer device of hard rock mole, the hob type cutterhead 5 of described hydraulic impact hammer device and hard rock mole is used, and may further comprise the steps:
Step 1: utilize 5 pairs of rock mass of hob type cutterhead to carry out cut, by adjusting adjusted cylinder 7 and regulating cylinder 8 down, change the position of cutting arm 6, and then change the cut position of hob type cutterhead 5, finally making rock mass form one has the rectangle of certain depth to cut groove;
Step 2: rectangle cuts the groove cut finish after, adjust adjusted cylinder 7 again and regulate cylinder 8 down, make hob type cutterhead 5 return to position away from rock mass;
Step 3: the hydraulic impact hammer device starts, and under the effect of hydraulic cylinder 3, tup 1 and hammer handle 2 begin to do reciprocal stretching motion;
Step 4: adjust adjusted cylinder 7 and the following cylinder 8 of regulating, make tup 1 slowly cut the edge of groove near rectangle, up to the touching rock mass, tup 1 begins the hammering rock mass, and fragmentation comes off after rock mass is being subjected to hammering.
