Description

Technical Field

[0001] The invention relates to the technical field of drilling rig assistance, in particular to a geological drilling rig assistance device for uncovered weight consolidation grouting construction. Background Art

[0002] In the process of dam foundation construction, consolidation grouting is a key technical measure, which aims to fill cracks and improve the integrity and strength of the rock mass by injecting slurry into the bedrock, thereby ensuring the stability and bearing capacity of the dam foundation. With the continuous expansion of the scale of water conservancy and hydropower projects and the continuous advancement of technology, the requirements for consolidation grouting construction technology are also increasing. Uncovered consolidation grouting refers to the direct grouting operation on the surface of the foundation rock without laying concrete. It is usually suitable for situations with low grouting pressure, tight construction period or good rock conditions. The introduction and widespread use of this technology can significantly alleviate the construction interference between foundation treatment and concrete pouring. When drilling, in order to avoid hole collapse, a support structure will be set for the hole during drilling.

[0003] Prior art 1 (application number CN202120348346.6, Chinese patent published on November 2, 2021) A peripheral auxiliary stabilization device for a grouting drill rig for coal mining in a coal mine, comprising a limit sleeve, both sides of the limit sleeve are movably interspersed with fixing bolts, one end of two fixing bolts is movably interspersed in the limit sleeve, and a clamping plate is movably installed on the end, and mounting sleeves are movably installed on both sides of the surface of the limit sleeve, and a rotating sleeve is fixedly installed at one end of the four mounting sleeves, and a rotating screw sleeve is movably installed in the rotating sleeve, and the rotating screw sleeve is movably connected to the mounting sleeve, and a telescopic screw is movably inserted in the rotating screw sleeve. The user inserts the grouting pipe into the interior of the limit sleeve, and the user rotates the fixing bolt, and one end of the fixing bolt moves toward the interior of the limit sleeve. Under the action of the limit spring column, the clamping plate prevents the clamping plate from rotating with the fixing bolt, affecting the movement of the clamping plate. At the same time, under the action of the convex strip, The fixation of the grouting pipe by the clamping plate is strengthened; Prior art 2 (application number CN202110810436.7, Chinese patent published on August 17, 2021) An engineering geological survey drilling rig, comprising a drilling rig body, a fixed base and a support frame movably connected to the surface of the drilling rig body, handles are fixedly connected on both sides of the drilling rig body, and the output shaft end of the drilling rig body is fixedly connected to the core tube through a coupling; the drilling rig body is placed on top of the fixed frame, at this time the handle is clamped inside the fixed frame, the limit bolt is turned, the limit bolt is inserted into the threaded groove, the fixed frame and the handle are fixed together, the drilling rig body is fixed, and the handle is pushed downward. The handle drives the connecting block to move downward in the support frame through the fixed frame. At this time, the limit block slides in the sliding groove, driving the ball to roll on the surface of the support frame, driving the core tube to move downward, and when encountering harder rock, the drilling rig body can drill downward smoothly and maintain a vertical downward angle.

[0004] When positioning the auxiliary support tube during the drilling process, it is generally done manually or by using the positioning holes on the drilling rig to assist in positioning. However, there is a large difference in diameter between the positioning holes on the drilling rig and the support tube, resulting in low positioning accuracy. In addition, when following the pipe for drilling, the direction of the support tube will also affect the drilling direction and affect the subsequent drilling inclination deviation. Currently, when the auxiliary device is supporting the drill rod or the support tube, if the device itself is not in a vertical state, the support will also deviate, reducing the positioning guidance accuracy of the device.

After the mounting seat 4 is fixed, the counterweight block 20 provides a downward pulling force for the movable ball 6 to keep the movable ball 6 in a vertical state, and the subsequent positioning direction is corrected. Then the rotation of the movable ball 6 can be limited to keep it stable, and the protective tube 3 can be clamped by the clamping mechanism. When the protective tube 3 is not in use, the clamping mechanism can also directly clamp the drill rod 2 to guide its drilling.

[0046] Embodiment 2: On the basis of embodiment 1, a clamping mechanism is disclosed, which includes a positioning block 7, a guide ball 8 and a driving mechanism.

[0048] Embodiment 3: On the basis of embodiment 2, a locking mechanism is provided on the outer side of the movable ball 6 to lock the rotation state of the movable ball 6. The locking mechanism includes a locking rod 15. The locking rod 15 passes through the front side of the mounting seat 4 and the mounting seat 4 to form a threaded connection. The locking rod 15 rotates and squeezes the movable ball 6 against each other. The mounting seat 4 and the movable ball 6 are both split-structure designs. The mounting seat 4 can be taken out from the outer side of the protective tube 3 after being disassembled. A connecting mechanism is provided on the outer side of the movable ball 6 to connect the split movable ball 6 and the mounting seat 4. The mounting seat 4 includes a first connecting block 401 and a second connecting block 402.

When the device is taken out from the outside of the drill pipe 2 or the protective tube 3 after use, the clamping effect of the positioning block 7 can be released first, and then the locking of the movable ball 6 by the locking rod 15 can be released. When adjusting the movable ball 6, the connecting piece 17 and the connecting groove 16 are relative, and the connecting piece 17 is rotated to connect it with the connecting groove 16 to position the movable ball 6, and then the mounting piece 18 can be rotated to release the connection between the mounting piece 18 and the mounting groove 19, so that the first connecting block 401 and the second connecting block 402 can be separated, and at the same time, the corresponding movable ball 6, counterweight block 20 and linkage plate 13 are separated accordingly, and the device can be conveniently moved out from the outside of the drill pipe 2.
