Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic tunnel construction, in particular to a hydraulic tunnel drilling and slag cleaning device. Background Art

[0002] In water conservancy construction, tunnels are important water conveyance structures. Mechanical drilling is often used in tunnel drilling construction. Due to cracks and pores in the tunnel, it is easy to produce debris residue in the hole during the drilling process, which in turn affects the subsequent drilling operation.

[0003] The patent with the announcement number CN219993650U discloses a hydraulic tunnel drilling and slag removal device, which drills hydraulic tunnels by rotating the drill tube. The fragments generated by drilling are collected inside the drill tube, and the fragments are transported to the inside of the shell by the auger. Under the action of gravity, they fall into the storage box for collection. Due to the limitation of the blade spacing, the auger can only handle smaller fragments. In actual use, due to the gaps in the surrounding rock structure in the tunnel, when drilling with the drill tube, stones with the same diameter as the inner wall of the drill tube may appear. The inner wall of the drill tube and the auger cannot crush such stone structures, causing the auger to get stuck and unable to be transported normally, which will make it impossible to continue the drilling operation.

[0004] In view of this, how to eliminate the defect that large fragments cannot be transmitted during the drilling operation has become a technical problem that technical personnel in this field urgently need to solve. Utility Model Content

[0005] The utility model aims to provide a hydraulic tunnel drilling and slag cleaning device to overcome the above-mentioned shortcomings.

[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is: a hydraulic tunnel drilling and slag cleaning device, comprising a housing and a drill barrel connected in the housing; a bearing is connected between the rotatable drill barrel and the housing; a first drive motor, a first gear, a second gear and a second drive motor are arranged in the housing, the first drive motor transmission shaft is connected to the first gear, and the first gear is meshed with the second gear sleeved on the drill barrel;

[0007] The second driving motor at the rear of the shell is connected to a rotating rod extending into the drill tube, on which an auger is arranged, and a crushing head which can move axially and rotate circumferentially along the axis of the drill tube is movably connected to the front end of the rotating rod.

[0008] Furthermore, a closed track groove is arranged around the side wall of the crushing head, and a radial protrusion is fixedly connected to the inner side wall of the drill barrel, and the protrusion is movably connected in the track groove; the rear end of the columnar crushing head is provided with an axial blind hole and a horizontal slide groove connected to the blind hole, and the front end of the rotating rod is fixedly connected to a radial sliding rod, and the front end of the rotating rod is axially movably connected in the blind hole of the crushing head, and the sliding rod is movably connected in the horizontal slide groove. During the drilling process of the drill barrel, the drill barrel and the rotating rod rotate at the same time, with different rotation speeds. The crushing head is simultaneously limited by the protrusion in the track groove and the sliding rod in the horizontal slide groove. The crushing head can simultaneously reciprocate axially and rotate circumferentially along the axis direction of the drill barrel, and can impact and crush the stones produced by drilling the drill barrel and perform rotational extrusion crushing, and crush larger fragments into smaller fragments for smooth auger transmission.

[0009] Furthermore, the trajectory groove includes a plurality of interconnected curved segments, so as to realize axial reciprocating motion of the crushing head along the axis direction of the drill barrel.

[0010] Furthermore, the curved line segment is a parabola, so that the crushing head can smoothly reciprocate axially along the axis direction of the drill tube.

[0011] Furthermore, the front end surface of the crushing head is provided with a plurality of linear first protrusions, and the outer side wall of the front end of the crushing head is provided with a plurality of annular second protrusions, the first protrusions are used for impacting and crushing stones, and the second protrusions are used for rotating and squeezing and crushing stones.

[0012] Furthermore, the transmission ratio between the first gear and the second gear is greater than 1, which can increase the torque of the drill tube.

[0013] Furthermore, a detachable storage box is provided at the lower end of the shell for collecting and processing the fragments.

[0014] Furthermore, a handle is installed at one end of the shell away from the crushing head for handheld operation of the device.

[0015] Furthermore, the first drive motor and the second drive motor are connected to a controller and a power supply for powering and controlling the device.

[0016] Compared with the prior art, the utility model has at least the following advantages: drilling of hydraulic tunnels is performed by rotating the drill tube, and the fragments generated by drilling are collected inside the drill tube. During the drilling process, the drill tube and the rotating rod rotate simultaneously, and the rotation speeds are different.

The crushing head can simultaneously reciprocate axially and rotate circumferentially along the axis direction of the drill tube, and can impact and crush the stones generated by drilling the drill tube and crush them by rotation and extrusion, and crush larger fragments into smaller fragments so that the auger can be smoothly transmitted. The defect that larger fragments are stuck and cannot be transmitted is solved. The crushed fragments are collected in the shell after rotation. The debris generated by drilling can be quickly crushed and cleaned up at the same time during the drilling process, realizing continuous drilling operations, and greatly improving the construction efficiency of drilling operations in hydraulic tunnels.
