Detailed Description
As shown in fig. 1 to 4, the present embodiment provides a novel hydraulic rock drill, including a rock drill body 100, a shank 110 connected to the rock drill body 100, a protection plate 200 and a measurement system; wherein,
a mounting hole is formed in the center of the protection plate 200, and the protection plate 200 is fixedly mounted at the end part of the rock drill body 100 connected with the drill shank 110 through the mounting hole; a first mounting groove for mounting the measuring system is concavely arranged at the end part of the rock drill body 100 connected with the drill shank 110, and a second mounting groove opposite to the first mounting groove is concavely arranged at the mounting hole of the protection plate 200;
the measuring system comprises a measuring rod 310, a spring 320, a sliding mounting block 330, a fixed mounting block 340 and a scale bar 350; the fixed mounting block 340 is mounted at the end part of the first mounting groove far away from the shank 110, one end of the spring 320 is connected with the fixed mounting block 340, the other end of the spring is connected with the sliding mounting block 330, one end part of the measuring rod 310 is connected with the end part of the sliding mounting block 330 far away from the spring 320, so that the measuring rod 310 can drive the sliding mounting block 330 to reciprocate in the first mounting groove, and the free end of the measuring rod 310 penetrates through the first mounting groove and the second mounting groove;
the scale bar 350 is arranged on the rock drill body 100 and is parallel to the axis of the first mounting groove, and length scale lines 351 are arranged on the scale bar 350, wherein the 0 scale line 351 is flush with the end face of the spring 320 connected with the sliding mounting block 330 when the spring 320 is in a natural state, and the scale number is gradually increased towards the direction far away from the drill shank 110; and when the spring 320 is in a natural state, the end surface of the measuring rod 310 far away from the rock drill body 100 is flush with the end surface of the drill shank 110 far away from the rock drill body 100.
In the above embodiment, the protection plate 200 can effectively block the broken stones and dust generated by the rock drilling of the drill bit shank 110 outside the hydraulic rock drill without damaging the structure of the hydraulic rock drill; the sliding installation block 330 realizes that when the drill bit shank 110 works, the measuring rod 310 can move towards the fixed installation block 340 along with the drilling depth due to the resistance of the object to be drilled, and simultaneously, when the drill bit shank 110 impacts the working part 400, the spring 320 can synchronously extend and retract along with the impact so as to ensure that the measuring rod 310 is always in contact with the working part 400 and accurately measure the drilling depth; in particular, the spring 320 can be easily replaced after its performance has been degraded or damaged, in order to measure and ensure the long-term normality of the function; as the shank 110 is drilled deeper, the distance the measuring rod 310 moves towards the fixed mounting block 340 is the exact depth of the current drilling.
Preferably, in order to make the drill bit shank 110 not easily get stuck by broken stones and the like during the drilling process of the hydraulic rock drill, the end of the drill bit shank 110 far away from the rock drill body 100 is concavely provided with a spiral groove 111, the section of the spiral groove 111 is in a V shape, and the spiral groove 111 axially extends towards the drill bit shank 110. The impurities such as crushed stones generated by the drill bit shank 110 impacting the working part 400 can smoothly move outwards from the rock hole through the spiral groove 111, and finally leave the drill bit shank 110 more smoothly, so that the drill bit shank 110 is not blocked to influence drilling.
Preferably, the measuring assembly further comprises two limit blocks 360, the two limit blocks 360 are symmetrically installed on the inner wall of the first installation groove, the distance between the two limit blocks 360 is greater than the diameter of the drill shank 110 and smaller than the width of the sliding installation block 330, and the end face of the limit block 360 close to the drill shank 110 is flush with the 0-scale line 351 of the scale strip 350. Two stopper 360 can guarantee that slidable mounting piece 330 can only be by 0 scale mark 351 department in first mounting groove to the sliding of fixed mounting piece 340 direction, and at this interval reciprocating motion, and can not cross 0 scale mark 351 and to guard plate 200 direction removal, and then guaranteed that slidable mounting piece 330 is when 0 scale mark 351, the terminal surface that rock drill body 100 was kept away from to measuring stick 310 and the terminal surface parallel and level that rock drill body 100 was kept away from to bore bit tail 110, the effectual measuring accuracy of having guaranteed.
The working principle of the embodiment is as follows:
when the hydraulic rock drill is used, whether the sliding installation block 330 is located at the 0 scale line 351 is firstly checked, otherwise, the sliding installation block is adjusted to be located at the 0 scale line 351, then the drill bit shank 110 is aligned with the working part 400 to start drilling operation, and the end part, far away from the protection plate 200, of the measuring rod 310 is also in contact with the working part 400. During the drilling process, the sliding mounting block 330 carries the measuring rod 310 to move towards the fixed mounting block 340 along with the drill shank 110, and when the sliding mounting block 330 slides to the graduation line 351 of the required drilling depth, the drilling operation is completed. In the process, broken stones, dust and the like generated by the impact of the drill bit shank 110 can smoothly leave the rock hole along the spiral grooves 111, and the drill bit shank 110 cannot be clamped; the partly splashed crushed stones and flying dust are blocked by the protective plate 200, and the operator of the hydraulic rock drill is not injured.
Finally, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the present invention can be modified or replaced by other means without departing from the spirit and scope of the present invention, which should be construed as limited only by the appended claims.
