Abstract
The utility model relates to a hydraulic impact hammer device additionally installed on a hard rock tunneling machine, and belongs to the technical field of hard rock tunneling, and particularly relates to the hydraulic impact hammer device additionally installed on the hard rock tunneling machine. The device comprises a hammer head, a hammer handle, a hydraulic cylinder and a connecting base, wherein the hammer head is fixedly connected with the hammer handle which is connected with one end of the hydraulic cylinder, and the other end of the hydraulic cylinder is connected with the connecting base. The device provided by the utility model is matched with a hob cutting head of the hard rock tunneling machine in use to overcome the technical deficiencies of existing hard rock tunneling machines, so that the device provided by the utility model is suitable for tunneling operation of large section full hard rocks and half-rock roadways. Compared with blasting mining operation, the device has the advantages that the risk of tunneling operation is greatly reduced and the labor intensity of operators is reduced; and the device not only is less in effect to structural strength of casing of the roadway, but also improves the cutting efficiency of the hard rock tunneling machine, furthermore, the reliability of the hard rock tunneling machine is ensured.
Description
Technical field
The utility model belongs to hard rock driving technology field, particularly relates to a kind of hydraulic impact hammer device 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.
The utility model content
Problem at the prior art existence, the utility model provides a kind of hydraulic impact hammer device that is installed in hard rock mole, the hob type cutterhead of this hydraulic impact hammer device and hard rock mole is used, excavation operation applicable to 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 utility model 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.
The beneficial effects of the utility model:
The hob type cutterhead of the utility model and hard rock mole is used, 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.
Description of drawings
Fig. 1 is a kind of hydraulic impact hammer apparatus structure schematic diagram that is installed in hard rock mole of the present utility model;
Fig. 2 is for being equipped with hard rock mole structural representation of the present utility model;
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
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
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.
The process that once is used below in conjunction with description of drawings the utility model and hard rock mole cutting units:
Shown in Fig. 2,3, before the use, at first hydraulic impact hammer device of the present utility model 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.
At first 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; After finishing the cut task that rectangle cuts groove, adjust adjusted cylinder 7 again and regulate cylinder 8 down, make hob type cutterhead 5 return to position away from rock mass; This moment, the hydraulic impact hammer device started, under the effect of hydraulic cylinder 3, tup 1 and hammer handle 2 are done reciprocal stretching motion, adjust adjusted cylinder 7 this moment and regulate cylinder 8 down, make tup 1 slowly cut the edge of groove near rectangle, up to the touching rock mass, tup 1 beginning hammering rock mass, fragmentation comes off after rock mass is being subjected to hammering.Because rectangle cuts groove and formed cavity in rock mass, cause rock mass fragmentation when being subjected to hammering to come off and understand being easy to of becoming.Repeat above-mentioned course of action, finally impel hard rock mole to keep efficient driving, thereby significantly improved drivage efficiency.
