Technical Field
[0001] This utility model belongs to the technical field of rotary drilling equipment, specifically, it relates to an outward outrigger stabilization system. Background Technology
[0002] Rotary drilling rigs, widely used in foundation engineering for hole drilling, play a crucial role in various construction projects. Their working principle primarily involves a power head driving the drill rod and drill bit to rotate and drill, cutting and breaking up the soil and rock to the surface. During construction, rotary drilling rigs need to withstand significant torque, axial force, and lateral force. Especially during drilling, the interaction between the drill bit and the soil and rock generates complex mechanical effects, making the rig prone to swaying and shifting. Therefore, rotary drilling rigs are typically equipped with outrigger systems, which extend outwards and support the rig on the ground during operation, improving the stability of the rotary drilling operation.
[0003] Existing rotary drilling rig outrigger systems have some shortcomings, such as limited support range, making it difficult to provide sufficient stability in complex terrain or with a large operating radius; and the outrigger adjustment method is not flexible enough to quickly adapt to different construction environments.
[0004] In view of this, this utility model is proposed. Utility Model Content
[0005] To address the shortcomings of existing rotary drilling rig outrigger systems, such as limited support range, difficulty in providing sufficient stability in complex terrain or large operating radii, and inflexible adjustment methods that cannot quickly adapt to different construction environments, the basic concept of this utility model is as follows:
[0006] An outward-facing outrigger stabilization system includes a drilling rig chassis and a support block connected to the drilling rig chassis. The support block is provided with a support adjustment mechanism and an adaptive mechanism.
[0007] The support adjustment mechanism includes a sliding column mounted on the support block. A hydraulic cylinder is mounted on the outer wall of one end of the sliding column. The sliding column is used to move and adjust the support range of the hydraulic cylinder. The hydraulic cylinder is used to support and stabilize the drilling rig chassis.
[0008] The adaptive mechanism includes a support plate, and a omnidirectional ball is provided at the top of the support plate. The omnidirectional ball is used to drive the support plate to make multi-angle adjustments to adapt to different inclined ground and improve support stability.
[0009] In a preferred embodiment of this utility model, the support adjustment mechanism further includes a slot formed on the outer wall of one side of the support block. A motor is provided on the inner wall of the slot, and a lead screw is connected to the output end of the motor. A threaded block is threadedly connected to the outer wall of the lead screw, and a connecting rod is provided on the outer wall of the threaded block. The end of the connecting rod away from the threaded block is disposed with the outer wall of the sliding column. A limiting slider is provided on the outer wall of the sliding column, and a sliding hole is formed on the outer wall of the support block. A limiting groove is formed on the inner wall of the sliding hole, and the outer wall of the limiting slider is slidably disposed on the inner wall of the limiting groove.
[0010] In a preferred embodiment of the present invention, the adaptive mechanism includes a movable seat disposed at the output end of the hydraulic cylinder, and the outer wall of the universal ball is movably disposed on the inner wall of the movable seat.
[0011] In a preferred embodiment of this utility model, the inner wall of the hollow groove on the outer wall of the support block is provided with a movable groove, the inner wall of the movable groove is movably connected to the outer wall of the connecting rod, the bottom end of the outer wall of the sliding column is provided with a support seat, and the outer wall of the support seat is provided with a support slide plate.
[0012] In a preferred embodiment of this utility model, there are four hydraulic cylinders, which are distributed symmetrically in pairs on the support block.
[0013] In a preferred embodiment of this utility model, the inner wall of the sliding hole on the outer wall of the support block is fitted with the outer wall of the sliding column, and the outer wall of the limiting slider is fitted with the inner wall of the limiting groove.
[0014] In a preferred embodiment of this utility model, the support plate is made of alloy steel.
[0015] Compared with the prior art, the present invention has the following advantages:
[0016] This invention uses a motor to drive a lead screw to rotate, which in turn causes the sliding columns on both sides to move outward. As the sliding columns move, they in turn drive the hydraulic cylinder to move. This allows the hydraulic cylinder to change its support range according to different working environments, thereby improving the support stability of the drilling rig chassis.
[0017] This invention allows the support plate at its bottom to be adjusted by the multi-angle change of the universal ball inside the movable seat. This enables the support plate to fully fit and support the ground when facing ground with different inclination angles, thereby further improving the support stability of the drilling rig chassis.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0027] like Figures 1 to 5 As shown, an outward-facing outrigger stabilization system is mounted on a drilling rig chassis 1, which has a support block 2. The outward-facing outrigger stabilization system includes a support adjustment mechanism 31 and an adaptive mechanism 32 mounted on the support block 2. The support adjustment mechanism 31 includes a sliding column 315 mounted on the support block 2, with a hydraulic cylinder 3111 mounted on the outer wall of one end of the sliding column 315. The sliding column 315 is used to adjust the support range of the hydraulic cylinder 3111, which is used to stabilize the drilling rig chassis 1. The adaptive mechanism 32 includes a support plate 323, with a universal ball 322 mounted on the top of the support plate 323. The universal ball 322 is used to drive the support plate 323 to perform multi-angle adjustments to adapt to different ground inclinations and improve support stability.
[0028] Furthermore, the support adjustment mechanism 31 also includes a slot formed on the outer wall of one side of the support block 2. A motor 311 is provided on the inner wall of the slot. A lead screw 312 is connected to the output end of the motor 311. A threaded block 313 is threadedly connected to the outer wall of the lead screw 312. A connecting rod 314 is provided on the outer wall of the threaded block 313. The end of the connecting rod 314 away from the threaded block 313 is connected to the outer wall of the sliding column 315. A limit slider 316 is provided on the outer wall of the sliding column 315. A sliding hole is formed on the outer wall of the support block 2. A limit groove 317 is formed on the inner wall of the sliding hole. The outer wall of the limit slider 316 is slidably disposed on the inner wall of the limit groove 317.
[0029] Furthermore, the inner wall of the hollow groove on the outer wall of the support block 2 is provided with a movable groove 318. The inner wall of the movable groove 318 is movably connected to the outer wall of the connecting rod 314. A support seat 319 is provided at the bottom of the outer wall of the sliding column 315, and a support slide plate 3110 is provided on the outer wall of the support seat 319.
[0030] Furthermore, there are four hydraulic cylinders 3111, which are symmetrically distributed in pairs on the support block 2. The inner wall of the sliding hole on the outer wall of the support block 2 is fitted with the outer wall of the sliding column 315, and the outer wall of the limiting slider 316 is fitted with the inner wall of the limiting groove 317. In this way, the drilling rig chassis 1 can be supported and stabilized simultaneously from the top, bottom, left and right sides, thereby improving the working stability of the drilling rig chassis 1.
[0031] The adaptive mechanism 32 also includes a movable seat 321 disposed at the output end of the hydraulic cylinder 3111, and the outer wall of the universal ball 322 is movably disposed on the inner wall of the movable seat 321.
[0032] Furthermore, the support plate 323 is made of alloy steel. By using alloy steel, which has high strength, high toughness and good fatigue performance, it can meet the strength and reliability requirements of the support plate 323 under high load working conditions of the drilling rig.
[0033] The implementation principle of the outward outrigger stabilization system in this embodiment is as follows: When it is necessary to provide stable support for the drilling rig chassis 1, the motor 311 is started first. Its output end will drive the lead screw 312 to rotate. As the lead screw 312 rotates, it will drive the threaded block 313 to move outward. At the same time, during the movement, it will drive the connecting rods 314 on the left and right sides to move. As the connecting rods 314 move, they will drive the sliding columns 315 on both sides to extend outward. As the sliding columns 315 move and extend, they will drive the hydraulic cylinders 3111 on both sides to move away from the drilling rig chassis 1. In this way, the distance between the hydraulic cylinders 3111 and the drilling rig chassis 1 can be adjusted left and right. This is how it can be used to handle some complex situations. In cases of terrain or large operating radius, the support range of the hydraulic cylinder 3111 can be adjusted according to actual usage, thereby improving the support stability of the drilling rig chassis 1 in different operating environments. During the outward movement of the sliding column 315, the limiting slider 316 on the outer wall will move synchronously within the limiting groove 317. This improves the support stability of the sliding column 315 through the cooperation between the limiting slider 316 and the limiting groove 317. At the same time, it can also drive the support seat 319 and the support slide plate 3110 at its bottom to move outward synchronously, thus supporting the downward force on the sliding column 315 and further improving the support stability of the drilling rig chassis 1.
[0034] Then, the hydraulic cylinder 3111 is activated, and its output end will drive the movable seat 321 and the support plate 323 to move downward until the bottom end of the support plate 323 contacts the ground. When facing the ground at different inclination angles, the support plate 323 will drive the universal ball 322 to move at multiple angles inside the movable seat 321. This allows the support plate 323 to be adjusted and changed at multiple angles. In this way, when facing the ground at different inclination angles, the bottom end of the support plate 323 can always be completely attached and supported, thereby improving the support stability of the drilling rig chassis 1.
