Description

Technical Field

[0001] This utility model relates to a drilling rig operation locking device, belonging to the field of anchoring component technology. Background Technology

[0002] Drilling rigs are widely used in the exploration and extraction of oil, natural gas, and mineral resources, as well as in geological exploration and groundwater extraction. With technological advancements, the performance of drilling rigs has been continuously improved, enabling them to adapt to more complex working environments.

[0003] When drilling in complex geological conditions, especially on slopes, the stability of the drilling rig is crucial. To prevent the rig from sliding or tilting on the slope and to ensure the safety and accuracy of the drilling process, the drill rod usually needs to be on the lower side of the slope and the rig on the upper side. This requires operators to have higher levels of skill and experience to deal with various unexpected situations.

[0004] The existing technology has at least the following technical problems:

[0005] Even when hydraulic outriggers are used to anchor the drilling rig during operation, high-frequency vibrations can still cause the rig to shift, resulting in poor stability and potentially leading to a major accident such as overturning. Sliding of the drilling rig can also cause uneven stress between the drill rod and the borehole wall, increasing friction and potentially causing the drill rod to break. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a drilling rig operation locking device to prevent the drilling rig from sliding and shifting during operation, thereby increasing the stability of the drilling rig during operation.

[0007] The drilling rig operation locking device of this utility model includes:

[0008] Locking device, used for hinged connection with drilling rig;

[0009] A linear drive mechanism is hinged to the drilling rig, and its output end is hinged to the locker to drive the locker to move.

[0010] The locker includes a hinged seat connected to the drilling rig and the linear drive mechanism, with a locking head connected to one side of the hinged seat, and locking teeth provided on the surface of the locking head.

[0011] Furthermore, the locker and linear drive mechanism are connected to both sides of the drilling rig.

[0012] Furthermore, the locker and linear drive mechanism are located on the inner side of the tracks on both sides of the drilling rig.

[0013] Furthermore, an extension rod is installed inside the hinge seat, and a locking head is connected to the end of the extension rod.

[0014] Furthermore, the extension rod has a crossbar at one end of the locking head, the crossbar is connected to the locking head, and is located in front of the track.

[0015] Furthermore, a reinforcing plate is provided on the crossbar, and the reinforcing plate is fixedly connected to the locking head.

[0016] Furthermore, the locking head has an arc-shaped working surface, on which several inverted triangular locking teeth are provided.

[0017] Furthermore, the arc-shaped working surface on the locking head can be a cylindrical tube, and the surface of the cylindrical tube is provided with several inverted triangular locking teeth.

[0018] Furthermore, the locking teeth are arranged in at least two rows along the axial direction of the cylindrical tube.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention significantly improves the stability of drilling rigs during operation. Through the hinged engagement of the locking device and the linear drive mechanism, a dynamic triangular support structure is formed with the drilling rig, ensuring its stability when operating on inclined surfaces. The meshing design of the locking teeth effectively increases the coefficient of friction, suppressing rig slippage and preventing accidents.

[0021] The curved working face adopts a variable diameter cylindrical design, which can automatically adjust the contact area according to the terrain undulations, maintain an effective contact ratio in complex geological conditions such as gravel and soft soil, and improve adaptability compared with traditional flat outriggers.

[0031] like Figures 1-5 As shown, the drilling rig operation locking device of this utility model includes:

[0032] Locking device 1 is used for hinged connection with drilling rig 3;

[0033] The linear drive mechanism 2 is hinged to the drilling rig 3, and its output end 21 is hinged to the locking device 1 to drive the locking device 1 to move. The linear drive mechanism 2 adopts a hydraulic cylinder, but can also adopt a pneumatic cylinder or an electric cylinder.

[0034] like Figure 5 As shown, the drilling rig 3 is welded with a first hinge point 31 and a second hinge point 32. The first hinge point 31 is used to hinge the locking device 1, and the second hinge point 32 is used to hinge the linear drive mechanism 2.

[0035] When in operation, the linear drive mechanism 2 drives the locker 1 to swing along the first hinge point 31. At this time, the locking head 12 at the front end of the locker 1 is pressed down, and the locking teeth 11 are pressed into the ground, so that the locker 1 and the track of the drilling rig 3 form a dynamic triangular support structure, which improves the stability of the drilling rig 3 when operating on a slope of 15° to 35°.

[0036] The locking device 1 includes a hinge seat 15 connected to the drilling rig 3 and the linear drive mechanism 2. A locking head 12 is connected to one side of the hinge seat 15, and locking teeth 11 are provided on the surface of the locking head 12.

[0037] Locker 1 and linear drive mechanism 2 are used to connect to both sides of the drilling rig 3, resulting in a better locking effect.

[0038] like Figure 4 As shown, the locking device 1 and the linear drive mechanism 2 are located on the inner side of the track. Installing the locking device 1 on the inner side of the track avoids interference with the drill rod and lowers the overall center of gravity height. When operating on a 30° slope, the center of gravity projection offset is reduced, significantly improving the anti-slip capability.

[0039] An extension rod 14 is installed inside the hinge base 15, and a locking head 12 is connected to the end of the extension rod 14.

[0040] The extension rod 14 is provided with a crossbar 141 on one side of the locking head 12. The crossbar 141 is used to connect the locking head 12. The crossbar 141 extends in the direction of the track and is located in front of the track.

[0041] A reinforcing plate 13 is also provided on the crossbar 141. The reinforcing plate 13 is fixedly connected to the locking head 12 to ensure the stability of the locking head 12.

[0042] The locking head 12 has an arc-shaped working surface, and several inverted triangular locking teeth 11 are provided on the arc-shaped working surface.

[0043] The arc-shaped working surface on the locking head 12 can be a cylindrical tube. The cylindrical tube surface is provided with several inverted triangular locking teeth 11. The arc-shaped working surface adopts a variable diameter cylindrical tube design, which can automatically adjust the contact area according to the terrain undulations and maintain an effective contact ratio under complex geological conditions such as gravel and soft soil, thus improving adaptability compared to traditional flat outriggers.

[0044] The locking teeth 11 are arranged in at least two rows or more along the axial direction of the cylindrical tube.

[0045] Working process or working principle:

[0046] The locking head 12 is kept in a retracted state by the linear drive mechanism 2 (hydraulic cylinder), the locking teeth 11 are completely out of contact with the ground, the tracks of the drilling rig 3 are in a free extended state, and the overall weight of the device is borne by the chassis of the drilling rig 3.

[0047] Oil begins to be injected into the rodless chamber of the hydraulic cylinder, pushing the piston rod to slowly extend. The locking head 12 descends along the rotation trajectory of the hinge seat 15, and the arc-shaped working surface gradually contacts the ground. Two or more rows of locking teeth penetrate the ground, forming an anchor to the ground.

[0048] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
