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 the hard rock driving method that are installed in hard rock mole.
Background technology
At present, in the face of the fully hard rock of big cross section and half rock gangway road, tunneling method mostly Bian big gun adopts operation.But operation adopted by big gun is a not only arduous but also dangerous job, and not only production efficiency is comparatively low, and the labour intensity of operator is very big.Often after operation adopted by big gun, certain destruction can be caused to roadway surrounding rock layer Jie Ju intensity.And existing hard rock mole is mainly applicable to medium-hard coal petrography and alternate heading, and be not suitable for fully hard rock gangway road operation; Hard rock mole is in tunneling process simultaneously, and when particularly running into 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 efficiency of excavation operation, has reduced the reliability of hard rock mole.
Summary of the invention
For prior art Problems existing, the invention provides a kind of hydraulic impact hammer device and the hard rock driving method that are installed in hard rock mole, the present invention is applicable to the excavation operation in the fully hard rock of big cross section and half rock gangway road, very little to roadway surrounding rock layer Jie Ju intensity effect, not only increase the cutting efficiency of hard rock mole, and ensure that the reliability of hard rock mole.
To achieve these goals, the present invention adopts following technical scheme: a kind of hydraulic impact hammer device being 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 one end of hydraulic cylinder, and the other end of described hydraulic cylinder is connected with Connection Block.
A kind of hard rock driving method being installed in the hydraulic impact hammer device of hard rock mole described in employing, the hob type cutterhead of described hydraulic impact hammer device and hard rock mole with the use of, comprise the following steps:
Step one: utilize hob type cutterhead to carry out cut to rock mass, makes rock mass be formed and cuts groove;
Step 2: cut after groove cut completes, makes hob type cutterhead return to position away from rock mass;
Step 3: hydraulic impact hammer device starts;
Step 4: make the tup of hydraulic impact hammer device near cutting the edge of groove, until touching rock mass, tup starts hammering rock mass, until rock mass broken fall.
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, be applicable to the excavation operation in the fully hard rock of big cross section and half rock gangway road, compared with adopting operation with big gun, greatly reduce the danger of excavation operation, reduce the labour intensity of operator, not only very little to roadway surrounding rock layer Jie Ju intensity effect, and improve the cutting efficiency of hard rock mole, also assures that the reliability of hard rock mole.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As shown in Figure 1, be installed in a hydraulic impact hammer device for hard rock mole, comprise tup 1, hammer handle 2, hydraulic cylinder 3 and Connection Block 4, described tup 1 and hammer handle 2 Joint, hammer handle 2 is connected with one end of hydraulic cylinder 3, and the other end of described hydraulic cylinder 3 is connected with Connection Block 4.
As shown in Figure 2,3, before using, 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, hard rock mole cutting units adopts hob type cutterhead.The control end of described hydraulic cylinder 3 is arranged in the control room of hard rock mole.When the fully hard rock of big cross section and half rock gangway road, in hard rock mole tunneling process, if now utilize separately hob type cutterhead 5 to carry out headwork, not only drivage efficiency can reduce greatly, the reliability of hard rock mole also can be made to reduce, so now just need hydraulic impact hammer device and hob type cutterhead 5 with the use of, to have continued headwork below.
A kind of hard rock driving method being installed in the hydraulic impact hammer device of hard rock mole described in employing, the hob type cutterhead 5 of described hydraulic impact hammer device and hard rock mole with the use of, comprise the following steps:
Step one: utilize hob type cutterhead 5 pairs of rock mass to carry out cut, by adjusting upper adjustment cylinder 7 and lower adjustment cylinder 8, 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 after groove cut completes, and adjustment is upper again regulates cylinder 7 and lower adjustment cylinder 8, makes hob type cutterhead 5 return to position away from rock mass;
Step 3: hydraulic impact hammer device starts, and under the effect of hydraulic cylinder 3, tup 1 and hammer handle 2 start to do reciprocal telescopic movement;
Step 4: adjustment regulates cylinder 7 and lower adjustment cylinder 8, make tup 1 slowly cut the edge of groove near rectangle, until touching rock mass, tup 1 starts hammering rock mass, until rock mass fragmentation after being subject to hammering comes off.
