In the prior art, most of the geological survey and drilling devices for geotechnical engineering use large-scale mechanical equipment for geological survey and drilling of rock and soil layers. However, when geological survey and drilling of rock and soil layers is required in remote areas with power shortage, no roads, and inconvenient equipment transportation, manual drilling devices are mostly used.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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-Figure 5 As shown, a drilling device for geotechnical engineering investigation includes a base 1 and a movable adjustment device 2; the movable adjustment device 2 is installed with a mounting frame 21, a first hydraulic cylinder 22 is fixedly installed on one side of the mounting frame 21, a first plunger 23 is movably installed on the output end of the first hydraulic cylinder 22, a first connecting block 24 is fixedly installed on one end of the first plunger 23, and a connecting plate 27 is fixedly connected to the other side of the first connecting block 24;

[0025] During operation, by driving the first hydraulic cylinder 22, when the first plunger 23 is extended and retracted, the first connecting block 24 is driven to move correspondingly through one end, so that the first connecting block 24 and the connecting plate 27 are linked to move longitudinally.

[0026] Furthermore, a mounting frame 21 is fixedly installed between the bases 1, and two support rods 25 are fixedly installed on one side of the mounting frame 21, and support sliders 26 are movably installed on one side of the two support rods 25, and the other sides of the two support sliders 26 are fixedly connected with a connecting plate 27;

[0027] During operation, when the connecting plate 27 is moving, in order to increase the stability of its movement, the supporting points of the mounting frame 21 are increased through the cooperation of the supporting rod 25 and the supporting slider 26, which is beneficial to the stability of the connecting plate 27 during movement.

[0028] Further, a movable frame 28 is fixedly installed on one side of the connecting plate 27, a second hydraulic cylinder 29 is fixedly installed on one side of the movable frame 28, a second plunger 31 is movably installed on the output end of the second hydraulic cylinder 29, a second connecting block 33 is fixedly installed on one end of the second plunger 31, and a fixing plate 32 is fixedly installed on the other side of the second connecting block 33;

[0029] During operation, by installing the second hydraulic cylinder 29 and the second plunger 31 , one end of the second plunger 31 drives the fixing plate 32 to perform corresponding horizontal movements through the second connecting block 33 , which is beneficial to adjust the lateral level of the drill rod 39 accordingly.

[0030] Furthermore, two limit rods 34 are fixedly installed on one side of the movable frame 28, and limit sliders 35 are movably installed on one side of the two limit rods 34, and the other side of the limit sliders 35 is fixedly connected to the fixing plate 32;

[0031] During operation, when the fixing plate 32 moves along with the second connecting block 33, it will shake left and right, which is not conducive to the drilling operation of the drill rod 39 on the ground. The fixing plate 32 is limited by the cooperation of the limiting rod 34 and the limiting slider 35 to prevent the drill rod 39 from shaking during operation.

[0032] Furthermore, a linear motion slide guide block 36 is fixedly installed on one side of the fixed plate 32, and a linear guide rail 37 is movably installed through one side of the linear motion slide guide block 36;

[0033] When working, the linear motion slide block 36 is driven by power supply, and the linear motion slide block 36 converts electrical energy into mechanical motion. Its basic principle is similar to that of a rotary motor, but its motion axis is a straight line rather than a rotating axis, so that the linear movement of the linear guide 37 drives the torque motor 38 to lift and lower.

[0034] Furthermore, a torque motor 38 is fixedly mounted on one side of the linear guide rail 37, and a drill rod 39 is fixedly mounted on the output end of the torque motor 38;

[0035] During operation, the rotation of the drill rod 39 is achieved by driving the torque motor 38, which is beneficial for the drill rod 39 to perform drilling operations on the ground.

[0036] Working principle: When the drilling position needs to be adjusted, the first hydraulic cylinder 22 is driven to make the first plunger 23 at the output end to perform telescopic movement inside it, so that one end of the first plunger 23 drives the connecting plate 27 to perform corresponding movement through the first connecting block 24. A movable frame 28 is fixed to one side of the connecting plate 27. When the connecting plate 27 moves, it drives the movable frame 28 to move the position of the drill rod 39 longitudinally, thereby changing the longitudinal drilling point of the drill rod 39. At the same time, the second hydraulic cylinder 29 can be driven to make the second plunger 31 drive the fixed plate 32 to perform corresponding horizontal displacement through the second connecting block 33 to change the horizontal position of the drill rod 39. When positioning the point, the torque motor 38 is driven to make the drill rod 39 rotate, and the linear motion sliding guide block 36 and the linear guide rail 37 are cooperated to realize the lifting and lowering of the drill rod 39 to perform drilling operations on the ground.

[0037] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
