Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a crawler type rock and soil drilling device. Background Art

[0002] Crawler geotechnical drilling rigs are mainly composed of a mainframe, a drilling tower, a drill rod, a crawler drive device, a hydraulic system, a pneumatic system, an electronic control system, etc. Among them, the mainframe is the core part of the entire device, responsible for providing power and control; the drilling tower is used to support the drill rod and the drill bit to ensure the accuracy and stability of drilling; the drill rod is an important part connecting the drill bit and the drilling rig, transmitting thrust and torque; the crawler drive device is responsible for driving the device forward or backward, and adjusting the forward direction.

[0003] When a crawler geotechnical drill is in use, a hydraulic support structure is set at the four corners of the workbench to improve its stability during drilling. For development sites such as mines, there are many stones scattered unevenly on the ground, and the ground flatness is poor. The hydraulic support structure is placed on the stones, which makes it impossible for it to fit tightly with the ground, thus causing instability. Therefore, before the hydraulic support structure is supported, the staff is required to manually clean the ground, but manual cleaning is troublesome.

[0004] To this end, we propose a crawler type rock drilling device to solve the above problems. Summary of the invention

[0005] The purpose of the utility model is to provide a crawler type rock drilling device to solve the problems raised in the above background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A crawler rock drilling device comprises a crawler drilling rig body and a workbench, the four corners of the workbench are respectively installed with hydraulic rods through brackets, and the bottom ends of the hydraulic rods are connected to a stabilizing plate through a connecting sleeve, and a cleaning component for cleaning ground rocks below the stabilizing plate is also installed at the bottom of the bracket, the cleaning component comprises a turntable and a cleaning plate installed at the edge of the turntable, a telescopic part 1 is connected to the bottom of the bracket, and the bottom of the telescopic part 1 is connected to a telescopic part 2 through a mounting plate, the turntable is rotatably connected to the mounting plate, and a connecting rod is hinged between the turntable and a piston block in the telescopic part 2, and when the telescopic part 2 is extended and retracted, the turntable is controlled by the connecting rod to drive the cleaning plate to rotate and clean.

[0008] In a further embodiment, the telescopic member 1 and the telescopic member 2 are formed by a pneumatic cylinder or a hydraulic cylinder.

[0009] In a further embodiment, the length of the cleaning plate is greater than the distance between the axis of the rotating disk and the farthest end of the stabilizing disk.

[0010] In a further embodiment, a plurality of notches are formed on the lower edge of the cleaning plate along the length direction.

[0011] In a further embodiment, a ball groove is provided inside the connecting sleeve, and a ball block is provided at the connecting end of the stabilizing disk and the connecting sleeve, and the ball block is rotatably sleeved with the ball groove.

[0012] In a further embodiment, the bottom of the stabilizing disk is provided with a plurality of protrusions protruding from the bottom surface of the stabilizing disk.

[0013] In a further embodiment, the protrusion has an inverted triangular pyramid structure.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model can clean the ground corresponding to the bottom of the stabilizing plate by arranging a cleaning component. The telescopic part 1 drives the cleaning plate to contact the ground, and the telescopic part 2 controls the cleaning plate to rotate when it is extended and retracted, thereby sweeping away the stones on the ground, providing a flatter supporting surface for the lowering support of the stabilizing plate, thereby improving its supporting stability. The entire cleaning process is completed through the mechanical structure, which not only saves the trouble of manual cleaning, but also effectively improves the cleaning efficiency.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-3A crawler type rock drilling device comprises a crawler type drilling rig body 1 and a workbench 2. The workbench 2 is located on the crawler of the crawler type drilling rig body 1. Extended brackets 3 are respectively installed at the four corners of the workbench 2, and a hydraulic rod 4 is installed on the bracket 3. The outer shell of the hydraulic rod 4 passes through the bracket 3 and is fixed to the bracket 3. The bottom end of the hydraulic rod 4 is connected to a stabilizing plate 6 through a connecting sleeve 5. When the hydraulic rod 4 is extended and retracted, the stabilizing plate 6 is driven to move up and down. When the stabilizing plate 6 contacts the ground, the stability of the crawler type drilling rig body 1 during operation can be improved. A cleaning assembly 7 for cleaning the ground rocks below the stabilizing plate 6 is also installed at the bottom of the bracket 3. The cleaning assembly 7 comprises a turntable 74 and a cleaning plate 76 installed on the edge of the turntable 74. A telescopic member 71 is vertically connected to the bottom of the bracket 3, and a mounting plate 72 is fixed on the bottom output shaft of the telescopic member 71. A telescopic member 2 73 is horizontally connected to the lower surface of the mounting plate 72 near the crawler drilling rig body 1. The telescopic member 1 71 and the telescopic member 2 73 use one of a cylinder or a hydraulic cylinder. The turntable 74 is rotatably connected to the lower surface of the mounting plate 72 near the side of the stabilizing plate 6, and the turntable 74 is connected to the piston block 731 in the telescopic member 2 73 through a connecting rod 75, and the two ends of the connecting rod 75 are respectively hinged to the turntable 74 and the piston block 731, so that when the telescopic member 2 73 is extended and retracted, the turntable 74 is controlled by the connecting rod 75 to drive the cleaning plate 76 to rotate and clean, thereby achieving the effect of cleaning the stones on the ground.

[0025] See also Figure 1-2 In order to ensure a good cleaning effect, the length of the cleaning plate 76 is set to be greater than the distance between the axis of the turntable 74 and the farthest end of the stabilizing plate 6, so as to ensure sufficient cleaning of the stones under the stabilizing plate 6. At the same time, a plurality of notch grooves 761 are opened along the length direction on the lower edge of the cleaning plate 76, so that some fine sand and gravel can be filtered out through the notch grooves 761, reducing the burden of the cleaning plate 76 during rotation cleaning.

[0026] See also Figure 4 Taking into account that the ground flatness is poor during actual use, in order to improve the supporting stability of the stabilizing plate 6, a ball groove 51 is provided inside the connecting sleeve 5, and a ball block 61 is provided at the connecting end of the stabilizing plate 6 and the connecting sleeve 5. The ball block 61 is rotatably sleeved with the ball groove 51, so that the inclination of the stabilizing plate 6 relative to the connecting sleeve 5 can be adjusted to multiple angles, thereby better fitting with the uneven ground, reducing the generation of support voids, and improving stability. At the same time, a plurality of protrusions 62 protruding from the bottom surface of the stabilizing plate 6 are provided at the bottom of the stabilizing plate 6. The protrusions 62 adopt an inverted triangular pyramid structure, which is beneficial to improving the gripping ability of the stabilizing plate 6 and further enhancing stability.
