Description

Technical Field

[0001] This invention relates to the field of soil testing technology, and more specifically to a sampling drilling rig for geological exploration. Background Technology

[0002] Geological exploration is an industry specializing in geophysical exploration, geological surveys, mineral resource exploration, and groundwater exploration. Its main purpose is to reveal underground geological structures, mineral distribution, and groundwater resources, providing fundamental geological data and scientific basis for resource development and environmental protection. Sampling drilling rigs are essential mechanical equipment in geological exploration, used to insert sampling tubes deep into the ground to achieve geological sampling at a certain depth.

[0003] The current sampling tube consists of an outer sampling tube and an inner sampling tube. The outer sampling tube is fitted over the inner sampling tube and is used to penetrate underground under impact force, while the inner sampling tube is used for storing geological samples. To increase the sampling depth, the upper and lower ends of the sampling tube are respectively equipped with external and internal threads for connection and extension. However, after the current sampling drilling rig impacts the sampling tube underground, the inner and outer sampling tubes need to be manually erected and connected by threads. Due to the weight of the sampling tube, multiple people are needed to fit the inner and outer sampling tubes together, erect it, align the threads, and rotate it for connection. This operation is laborious and inefficient. Therefore, a sampling drilling rig for geological exploration is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a sampling drilling rig for geological exploration to solve the problems existing in the prior art as mentioned in the background section.

A hydraulic cylinder is installed on the body to drive the lifting slide to rotate. A hydraulic vibratory hammer is installed on the lifting slide to hammer the sampling tube. A storage assembly is installed on the side wall of the lifting slide for quickly storing and removing the outer and inner sampling tubes. A pipe splicing assembly is installed on the other side wall of the lifting slide for removing the outer and inner sampling tubes from the storage assembly, allowing the lower end of the inner sampling tube to extend beyond the outer sampling tube, and then automatically splicing the outer and inner sampling tubes to achieve the corresponding sampling depth.

Detailed Implementation

[0024] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-7 The present invention provides the following technical solutions:

[0026] A sampling drilling rig for geological exploration includes a body 1, a tracked walking mechanism 2 installed on the left and right sides of the body 1, and a lifting slide 3 hinged to the front of the body 1. The body 1 is equipped with a hydraulic cylinder 4 for driving the lifting slide 3 to rotate. The hydraulic cylinder 4 can rotate the lifting slide 3 to a vertical position to facilitate geological sampling. The lifting slide 3 is equipped with a hydraulic vibratory hammer 5 for hammering the sampling tube, so that the sampling tube enters the geology. The side wall of the lifting slide 3 is equipped with a storage component 6 for quickly storing and removing the outer sampling tube 8 and the inner sampling tube 9.

[0027] The storage assembly 6 includes mounting brackets 61 installed on the upper and lower sides of the lifting slide 3, a rotating shaft 62 rotatably connected between the two mounting brackets 61, and end baffles 63 installed on the upper and lower sides of the rotating shaft 62. A support plate 64 is installed on the lower side of the rotating shaft 62. The support plate 64 has several "U"-shaped grooves. The support plate 64 is used to support the bottom of the sampling outer tube 8, so that the sampling inner tube 9 extends to the lower end of the sampling outer tube 8. A first motor 65 is installed on the mounting brackets 61 to drive the rotating shaft 62 to rotate. The rotation of the rotating shaft 62 can switch the position of the sampling tube on the storage assembly 6.

[0028] A clamping control mechanism 66 for quickly fixing and removing the sampling tube is installed in the middle of the rotating shaft 62. The clamping control mechanism 66 includes a housing 661 mounted on the rotating shaft 62, a plurality of fixing claws 662 mounted in the housing 661, and a telescopic rod 663 slidably connected in the housing 661. The rotating end of the fixing claws 662 is connected to an incomplete gear 664. A rack 665 that meshes with the incomplete gear 664 is mounted on the telescopic rod 663. The telescopic movement of the telescopic rod 663 can drive the fixing claws 662 on both sides to rotate, thereby clamping or releasing. A control frame 666 is vertically slidably connected inside 661. The upper end of the control frame 666 is provided with a limiting protrusion. The telescopic rod 663 is provided with a groove corresponding to the protrusion. The cooperation between the limiting protrusion and the groove can position the telescopic rod 663, so that the fixing claw 662 keeps clamping the sampling tube 8. The bottom of the control frame 666 is provided with a control block 667. The control block 667 is provided with a driving inclined surface. When the electric gripper 762 contacts and squeezes the driving inclined surface, it can make the control frame 666 slide upward, release the positioning state of the telescopic rod 663, and make the sampling tube easy to remove.

[0029] A pipe fitting extension assembly 7 is installed on the other side wall of the lifting slide 3. The pipe fitting extension assembly 7 is used to remove the sampling outer tube 8 and sampling inner tube 9 from the storage assembly 6, and to extend the lower end of the sampling inner tube 9 out of the sampling outer tube 8. Then, the sampling outer tube 8 and sampling inner tube 9 are automatically reconnected to achieve the corresponding sampling depth. The pipe fitting splicing assembly 7 includes a linear slide 71 mounted on the side support of the lifting slide 3, a mounting plate 72 mounted on the output end of the linear slide 71 via the support, and support rings 73 mounted on the upper and lower ends of the mounting plate 72. A rotating frame 74 is rotatably connected inside the support ring 73. The rotating frame 74 is a cylindrical structure with an opening on the side. A rotary drive mechanism 75 for driving the rotating frame 74 to rotate is mounted on the mounting plate 72. The rotary drive mechanism 75 includes a gear ring 751 keyed to the rotating frame 74, a second motor 752 mounted on the mounting plate 72, and a drive gear 753 mounted on the output end of the second motor 752. The drive gear 753 meshes with the gear ring 751 to drive the rotating frame 74 to rotate, thereby driving the sampling tube to rotate.

[0030] The rotating frame 74 is equipped with two sets of continuous clamping mechanisms 76, which are distributed vertically within the rotating frame 74. The continuous clamping mechanism 76 on the lower side of the rotating frame 74 is used to clamp the inner sampling tube 9, and the continuous clamping mechanism 76 on the upper side of the rotating frame 74 is used to clamp the outer sampling tube 8. The continuous clamping mechanism 76 includes a connecting rod 761 vertically installed on the inner wall of the rotating frame 74 and an electric gripper 762 slidably connected to the connecting rod 761. A return spring 763 is installed on the connecting rod 761 to drive the electric gripper 762 to move upward and reset. The vertically movable setting of the continuous clamping mechanism 76 allows it to move downward when the sampling tube is threaded, so that the sampling tube can be smoothly threaded.

[0031] The working process of this invention is as follows:

[0032] When geological exploration sampling is required, the sampling tube is first placed in the storage component 6, and the inner sampling tube 9 is placed in the outer sampling tube 8, so that the bottom of the outer sampling tube 8 is on the support plate 64, and the bottom of the inner sampling tube 9 is on the end baffle 63 on the lower side of the rotating shaft 62. The outer sampling tube 8 is pushed towards the clamping control mechanism 66, so that the outer sampling tube 8 squeezes the telescopic rod 663. The telescopic rod 663 drives the fixed claw 662 to rotate through the rack 665 and the incomplete gear 664, thereby clamping the outer sampling tube 8 and positioning the telescopic rod 663 by the control frame 666, thus completing the storage of the sampling tube.

[0033] The sampling drill is driven to the sampling location. The hydraulic cylinder 4 drives the lifting slide 3 to rotate to the sampling state. The linear slide 71 drives the mounting plate 72 to move towards the storage component 6, and causes the continuing clamping mechanism 76 on the upper side of the rotating frame 74 to contact and press against the inclined surface of the control block 667. The control frame 666 moves upward, causing the fixing claw 662 to release the sampling outer tube 8. The continuing clamping mechanisms 76 on the upper and lower sides of the rotating frame 74 clamp the sampling outer tube 8 and the sampling inner tube 9 respectively, and move to directly below the hydraulic vibratory hammer 5. The hydraulic vibratory hammer 5 moves downward and contacts the top of the sampling tube. The continuing clamping mechanism 76 disengages, and the hydraulic vibratory hammer 5 applies a downward force to the sampling tube, causing the sampling tube to enter the ground.

[0034] After the first sampling tube enters the ground, the first motor 65 drives the rotating shaft 62 to rotate, causing the next sampling tube to enter the sampling position. The pipe splicing assembly 7 removes the sampling tube and moves it to a position directly below the hydraulic vibratory hammer 5. The electric gripper 762 on the lower side of the rotating frame 74 releases the inner sampling tube 9, allowing the inner sampling tube 9 to connect with the threaded inner sampling tube 9 that has already entered the ground under the action of gravity. The electric gripper 762 clamps the inner sampling tube 9 again, and the second motor 752 drives the rotating frame 74 to rotate, causing the inner sampling tube 9 to rotate for threaded connection. After the inner sampling tube 9 is connected, the electric gripper 762 on the lower side of the rotating frame 74 releases, and the electric gripper 762 on the upper side also releases, causing the outer sampling tube 8 to fall under the action of gravity and connect with the threaded outer sampling tube 8 below. The rotating frame 74 rotates again to achieve threaded connection of the outer sampling tube 8. The hydraulic vibratory hammer 5 continues to impact. Repeating this operation can achieve sampling of deep geological layers.
