Description

Technical Field

[0001] This utility model relates to the field of vehicle-mounted drilling rig technology, and more specifically, to a lifting mechanism for a vehicle-mounted drilling rig. Background Technology

[0002] Truck-mounted drilling rigs are mainly used for core or soil core sampling operations in fields such as geology and geotechnical engineering. Their core components include the drilling rig itself, power system, hydraulic system, core drilling bits, and trailer chassis. They are moved by trailer towing. The equipment typically employs a modular design, allowing the drilling rig to be flexibly adjusted in angle to adapt to vertical or inclined core sampling requirements in different geological formations. Compared to self-propelled equipment, they are more compact, lower in cost, and suitable for operation in relatively flat terrain or areas with good road conditions. They are widely used in building foundation investigation, mineral exploration, and other scenarios. Truck-mounted drilling rigs utilize hydraulic... Driven by the engine, the hydraulic pump generates high-pressure oil, which controls the rotation of the drilling host through the oil circuit. The drill bit rotates at high speed under the drive of the turntable to cut the strata, allowing the drill bit to continuously cut into the rock and soil layers. The rock core or soil core produced by cutting enters the core tube for storage along the inner cavity of the drill bit. The equipment cools the drill bit and removes the cuttings through a mud pump or water circulation system. When the core tube is full, the drill bit is lifted to retrieve the complete core sample, completing one core sampling operation. This cycle is repeated to achieve continuous drilling and sampling. Since the raising and lowering of the drill bit directly affects the drilling and feeding effect of the drill bit, it is necessary to raise and lower the drill bit.

[0003] In related technologies, during the use of vehicle-mounted drilling rigs, a stud is generally installed inside the drilling host. By rotating the stud, the operator applies a lifting and lowering threaded thrust to the drilling host, which in turn drives the drill bit to perform lifting and lowering drilling operations.

[0004] However, in the current use of truck-mounted drilling rigs, due to the use of stud threads for propulsion, it is difficult to stabilize the studs after use. When the truck-mounted drilling rig is towed by external vehicles, the studs are easily affected by road bumps, causing the drill bit position to be unstable, which affects the ease of lifting and positioning and the stability of the truck-mounted drilling rig during transfer.

[0030] Reference Figures 1-4 This utility model provides a technical solution: a vehicle-mounted drilling rig lifting mechanism, including a vehicle-mounted drilling rig 1 and a lifting and positioning mechanism. A lifting frame 2 is installed on the front side of the top of the vehicle-mounted drilling rig 1, a drill base 3 is installed on the inner side of the lifting frame 2, and a drill bit 4 is installed on the front side of the bottom of the drill base 3. This mechanism can provide the user with a medium for lifting the drill base 3 and a medium for positioning the drill base 3, so that the user can perform stable height positioning of the drill base 3 after operation, avoiding the situation where the drill base 3 is difficult to stabilize in height positioning during use. Therefore, it improves the convenience of lifting and positioning and the stability of transfer of the drill base 3.

[0031] Reference Figures 1-4 In a preferred embodiment, the lifting and positioning mechanism includes a stud 5 threadedly connected to the inside of the drill base 3. A turntable 6, fixedly connected to the stud 5, is movably connected to the inside of the lifting frame 2. A positioning head 7 is movably connected to the left side of the turntable 6. A positioning groove 8 is formed at the bottom of the outer side of the turntable 6. The right side of the positioning head 7 is located inside the positioning groove 8. A positioning connection mechanism is fixedly connected to the left side of the top of the lifting frame 2. After the turntable 6 rotates the stud 5 to apply a threaded lifting operation to the turntable, the positioning head 7 is moved into the positioning groove 8. This allows the positioning head 7 to engage with the positioning groove 8 and, through the turntable 6, perform insertion and positioning of the stud 5. The stud 5 is kept in position, thereby stabilizing the height of the drill base 3 and the drill bit 4. The positioning connection mechanism includes a connecting box 9, a connecting column 10, and a connecting rod 11. The connecting box 9 is fixedly connected to the left side of the top of the lifting frame 2, and the connecting column 10 is movably connected inside the connecting box 9. The left side of the positioning head 7 is fixedly connected to the right side of the connecting column 10, and the connecting rod 11 is fixedly connected to the left side of the connecting column 10. This allows the positioning head 7 to be connected to the lifting frame 2, so that the user can move the positioning head 7 flexibly and avoid the positioning head 7 from shifting position or separating from the lifting frame 2 during use, thus improving the working stability of the positioning head 7.

[0032] Reference Figures 2-3In a preferred embodiment, a translation groove 12 is provided at the bottom of the connecting post 10, and a translation seat 13 is movably connected inside the translation groove 12. The left side of the translation seat 13 is fixedly connected to the inner wall of the connecting box 9. This allows for translational connection between the connecting post 10 and the connecting box 9 to prevent displacement, thus avoiding positional displacement of the connecting post 10 during use. Therefore, the operating position stability of the connecting post 10 is improved. Push grooves 14 are provided on the right sides of both the translation groove 12 and the translation seat 13. A spring 15 is provided inside the translation groove 12, and the outer side of the spring 15 is connected to the inner wall of the push groove 14.

[0033] Reference Figures 2-4 In a preferred embodiment, a stabilizing seat 16 is movably connected to the left side of the front of the connecting rod 11, and a supporting seat 17 is movably connected to the right side of the front of the connecting rod 11. This stabilizes and supports the positioning head 7 during operation, thus improving the operational stability and convenience of the positioning head 7. An opening 18 is provided on the left side of the connecting box 9, located at the top of the connecting rod 11. This opening provides space for the stabilizing seat 16 and the supporting seat 17 to move out of the connecting box 9, thus improving the smoothness of operation of the stabilizing seat 16 and the supporting seat 17.

[0034] Reference Figures 2-4 In a preferred embodiment, a sleeve 19 is movably connected to the outside of the connecting rod 11. The front side of the sleeve 19 is fixedly connected to the rear side of the stabilizing seat 16 and the supporting seat 17. A position bar 20 located on the left side of the stabilizing seat 16 is fixedly connected to the front side of the sleeve 19, which allows for a rotatable connection between the stabilizing seat 16, the supporting seat 17, and the connecting rod 11. This eliminates the need for the user to know the exact position of the stabilizing seat 16 and the supporting seat 17, thus improving the ease of operation of the stabilizing seat 16 and the supporting seat 17. A threaded groove 21 is provided on the left side of the connecting rod 11, and a bolt 22 located on the outside of the sleeve 19 is threaded inside the threaded groove 21. This allows for a barrier connection between the sleeve 19 and the connecting rod 11, thus improving the connection effect between the sleeve 19 and the connecting rod 11.

[0035] Specifically, the working process or working principle of this vehicle-mounted drilling rig lifting mechanism is as follows: When the drill base 3 needs to be lifted, the hand-held turntable 6 rotates the stud 5 to apply a threaded thrust for lifting and moving the drill base 3, thus lifting the drill base 3 and drill bit 4. At this time, the lifting frame 2 provides lifting support and guidance between the drill base 3 and the vehicle-mounted drilling rig 1 during the lifting process. After the lifting operation of the drill base 3 and drill bit 4 is completed, when positioning is required, the hand-held sleeve 19 drives the support seat 17 and the stabilizing seat 16 to rotate on the left side of the connecting box 9, aligning the support seat 17, the stabilizing seat 16, and the movable opening 18. At this time, the spring 15, in conjunction with the translation seat 13, applies a rightward moving insertion and reset force to the positioning head 7 through the connecting column 10, causing the positioning head 7 to enter the positioning groove 8. This prompts the positioning head 7 to cooperate with the positioning groove 8 and the turntable 6 to perform insertion and positioning work between the stud 5 and the lifting frame 2, thereby stabilizing the drill base 3 and drill bit 4. During this process, the translation seat 1... 3. Moving inside the translation groove 12, the connecting column 10 and the connecting box 9 are translated to prevent displacement. At this time, the connecting rod 11 drives the sleeve 19 to move to the right with the connecting column 10, so that the stabilizing seat 16 and the support seat 17 enter the connecting box 9 through the movable port 18. At the same time, the bolt 22 cooperates with the screw groove 21 to block the connection between the sleeve 19 and the connecting rod 11. When the positioning column enters the positioning groove 8, it means that the stabilizing seat 16 and the support seat 17 have entered the connecting box 9 through the movable port 18. At this time, the sleeve 19 is held to drive the stabilizing seat 16 and the support seat 17 to rotate and displace the movable port 18. At the same time, the position bar 20 moves with the sleeve 19 so that the user can clearly see the position of the support seat 17 and the stabilizing seat 16, so that the left side of the stabilizing seat 16 contacts the left side of the inner wall of the connecting box 9. Through the sleeve 19 cooperating with the connecting rod 11 and the connecting column 10, the position of the positioning column is blocked and stabilized, ensuring the positioning stability of the positioning head 7 and the turntable 6 for the stud 5.

[0036] It should be noted that the vehicle-mounted drilling rig 1, the lifting frame 2, the drill base 3, and the drill bit 4 are all existing devices or equipment, or devices or equipment that can be implemented with existing technology. Their power supply, specific composition, and principles are clear to those skilled in the art, so they will not be described in detail here.
