Description

Technical Field

[0001] This utility model relates to the field of drilling casing installation and removal technology, specifically to an auxiliary device for casing installation and removal in geological exploration drilling. Background Technology

[0002] With the continuous acceleration of infrastructure construction in my country, more and more engineering projects are being carried out in complex geological environments such as plateaus, valleys, beaches, slopes, and wharves during the geotechnical engineering investigation process for industrial and civil buildings, water conservancy and hydropower, ports and wharves, highways, and railways. In such complex geological environments, it is inevitable to encounter loose deposits, saturated sand, karst caves, soft soil, and special fractured rock masses. In order to clarify the spatial distribution of complex strata and unfavorable geological bodies, during the drilling process, in order to ensure the stability of the borehole wall and prevent borehole collapse or drill bit burial, and to speed up the drilling speed, it is often necessary to use casing to protect the borehole opening to a certain depth or to drill with casing.

[0003] During drilling, casing needs to be installed or removed frequently. The manual installation and removal of casing involves one person holding a chain pipe wrench to hold the rear casing while another person holds a chain pipe wrench to hold the front casing for installation and removal. These operations are time-consuming and labor-intensive. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1 A casing installation and removal auxiliary device for geological exploration drilling includes an installation / removal bracket 10, a clamping and adjusting assembly 20, and several sets of clamping assemblies 30. The sets of clamping assemblies 30 are connected to the outside of the installation / removal bracket 10, and the enclosing space of the clamping assemblies 30 is adjusted by the cooperation of the clamping and adjusting assembly 20 and the installation / removal bracket 10, thereby allowing the drilling casing to be clamped in the center. The top of the installation / removal bracket 10 can be connected to a drive motor, which drives the entire device to rotate, and also allows the device to rotate the clamped drilling casing. Additionally, the drive motor can be mounted on a linear lifting mechanism, which can employ a hydraulic push rod, a pneumatic push rod, a ball screw lifting structure, or other existing structures capable of lifting. Thus, by adjusting the height of the casing installation and removal auxiliary device driven by the linear lifting mechanism, and by rotating the casing installation and removal auxiliary device and the drilling casing driven by the drive motor, the drilling casing can be installed or removed.

[0023] See Figure 2 The mounting bracket 10 includes a connecting frame 11, a lead screw 12, a base cylinder 13, and two sets of movable support parts 14. The lead screw 12 is disposed inside the connecting frame 11, and the base cylinder 13 is disposed below the connecting frame 11. The connecting frame 11 is used to coaxially fix the lead screw 12 and the base cylinder 13. In this embodiment, the connecting frame 11 may include a hanger 111, a multi-segment drive connecting part 112, and a sleeve 113. The bottom of the drive connecting part 112 is fixedly connected to the top of the lead screw 12, and the sleeve 113 is sleeved on the top of the base cylinder 13 and fixedly connected thereto. The multi-segment drive connecting part 112 is disposed between the hanger 111 and the sleeve 113 and connects the hanger 111 and the sleeve 113 into a whole. The two sets of movable support parts 14 are spaced apart on the base cylinder 13, and the two sets of movable support parts 14 are used to connect with several sets of clamping assemblies 30. In this embodiment, the movable support 14 may include a fixing ring 141, first lugs 142 in number equal to the number of clamping assemblies 30, and movable support frames 143. The fixing ring 141 is sleeved on the outside of the bottom cylinder 13 and fixedly connected thereto. A plurality of first lugs 142 are formed at equal intervals on the outer wall of the fixing ring 141. Each first lug 142 is rotatably connected to the adjacent end of a movable support frame 143. The end of the movable support frame 143 away from the first lug 142 is rotatably connected to the clamping assembly 30, thereby forming a parallel linkage structure between the clamping assembly 30 and the movable support frames 143 in the two sets of movable support parts 14, and allowing the plurality of clamping assemblies 30 to adjust their enclosed space together under the deflection movement of the two movable support frames 143 connected thereto.

[0024] See Figure 3The clamping and adjusting assembly 20 includes a lead seat 21, a movable ring 22, and adjusting brackets 23 in number equal to those in the clamping assembly 30. The lead seat 21 is sleeved on and threadedly connected to the lead screw 12, and the movable ring 22 is sleeved on the outside of the lead seat 21 and rotatably connected to it. In this embodiment, the lead seat 21 is dumbbell-shaped, and the movable ring 22 is sleeved on the middle section of the lead seat 21. The inner diameter of the movable ring 22 is larger than the outer diameter of the middle section of the movable ring 22, and the inner diameter of the movable ring 22 is smaller than the outer diameter of the top and bottom sections of the lead seat 21, so that when the lead seat 21 rotates and moves outside the lead screw 12, the movable ring 22 can maintain its position in the middle section and be driven by the top and bottom sections of the lead seat 21 to move axially along the lead screw 12, thereby allowing the movable ring 22 to adjust its height position through the threaded engagement between the lead seat 21 and the lead screw 12. The outer wall of the movable ring 22 has a number of second lugs 221 equal to the number of clamping components 30. Each second lug 221 is rotatably connected to the adjacent end of an adjusting bracket 23, and the end of the adjusting bracket 23 away from the second lug 221 is rotatably connected to the clamping component 30. Thus, when the movable ring 22 is adjusted in height, the two ends of several adjusting brackets 23 are rotatably connected to the movable ring 22 and the adjacent clamping component 30, respectively, so that the deflection of the adjusting bracket 23 drives the clamping component 30 connected to it to adjust its position under the support of the mounting bracket 10.

[0025] See Figure 4 The clamping assembly 30 includes connecting arms 31 that are rotatably connected to adjacent movable support frames 143 and adjacent adjusting brackets 23 in the two sets of movable support parts 14. A base 32 is formed at the bottom of the connecting arm 31, and a drilling casing clamping member 33 is provided below the base 32 and is detachably fixed to the base 32 by fasteners such as bolts. When the position is adjusted, several drilling casing clamping members 33 can simultaneously approach inward and make contact with the drilling casing using the arc-shaped groove 331 formed on the inner side of the drilling casing clamping member 33, and then clamp the drilling casing using the several drilling casing clamping members 33.

[0026] When using this device, the screw seat 21 in the clamping and adjusting assembly 20 is rotated to move it along the axial direction of the screw 12. The movement and deflection of the adjusting bracket 23 push the connecting arm 31 in the clamping assembly 30, and it moves closer to the drilling casing under the deflection support of the two movable support frames 143 in the installation and removal bracket 10. After the drilling casing is clamped by several drilling casing clamping parts 33 in the clamping assembly 30, the device and the drilling casing can be rotated by the drive motor. The linear lifting mechanism drives the drive motor, the device and the drilling casing to move along the height direction to complete the installation or removal of the drilling casing.
