For example, they can refer to a fixed connection, a replaceable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0020] Combination Figure 1-7 As shown, a drilling rig isolation and protection fence includes: a drilling rig body 1, a drive assembly 2, a transmission assembly 3, and an isolation fence 4; the drive assembly 2 consists of four sets, which are connected in pairs to the two sides of the drilling rig body 1 in the front-rear direction. Each drive assembly 2 includes a hydraulic cylinder 21, a support plate 22, and a toothed plate 23. The hydraulic cylinder 21 is fixedly connected to the drilling rig body 1. The support plate 22 and the toothed plate 23 are respectively installed at the power output end of the hydraulic cylinder 21, with the support plate 22 located at the bottom end of the power output end of the hydraulic cylinder 21. The hydraulic cylinder 21 can drive the support plate 22 and the toothed plate 23 in the vertical direction. The linear reciprocating motion; each set of drive components 2 is connected to a set of transmission components 3, each transmission component 3 including a gear 31 and a lead screw 32. The gear 31 meshes with the gear plate 23, the lead screw 32 extends in the left-right direction and passes through the gear 31, the lead screw 32 is screwed to the gear 31, and the lead screw 32 is slidably connected to the drill body 1; there are two sets of isolation fences 4, which are arranged opposite to each other on both sides of the drill body 1 in the left-right direction. The two ends of the isolation fences 4 are respectively connected to the outer ends of the lead screw 32, and the isolation fences 4 are slidably connected to the drill body 1 through the lead screw 32.

[0021] When the drilling rig body 1 needs to move, the hydraulic cylinder 21 drives the support plate 22 and the toothed plate 23 to move upward, causing the support plate 22 to release its support from the drilling rig body 1. The tracks on the drilling rig body 1 then contact the ground and move forward. At the same time, the toothed plate 23 drives the gear 31 to rotate. Because the gear 31 is threadedly connected to the lead screw 32, the lead screw 32 rotates under axial force and moves outward from the drilling rig body 1. Therefore, the isolation fence 4 moves outward from the drilling rig body 1 to form a protective barrier. Figure 1As shown, the isolation fence 4 is in the deployed state at this time, preventing personnel and vehicles from entering the blind spot of the drilling rig body 1 and causing safety hazards. This also helps eliminate interference from external personnel and vehicles during the drilling rig body 1's movement. During the positioning operation of the drilling rig body 1, the hydraulic cylinder 21 drives the support plate 22 and the toothed plate 23 to move downwards. The four sets of support plates 22 can support the drilling rig body 1 against the ground, improving the stability of the drilling rig body 1 during operation. The movement of the toothed plate 23 drives the gear 31 to rotate, which in turn drives the lead screw 32 to move inwards towards the drilling rig body 1. Therefore, the isolation fence 4 moves inwards towards the drilling rig body 1. Figure 7 As shown, the isolation fence 4 is in the retracted state at this time. The isolation fence 4 can be adjusted between the extended and retracted states, which does not affect the normal use of the drilling rig body 1, and also achieves dynamic protection for the drilling rig body 1.

[0022] Furthermore, the isolation fence 4 includes a first fence 41 and a second fence 42. The front end of the first fence 41 is fixedly connected to a set of lead rods 32, the front end of the second fence 42 is detachably connected to the rear end of the first fence 41, and the rear end of the second fence 42 is rotatably connected to another set of lead rods 32.

[0023] In this embodiment, when the first fence 41 and the second fence 42 are connected, they work together to isolate and protect both sides of the drilling rig body 1. After the connection between the first fence 41 and the second fence 42 is released, rotating the second fence 42 makes it easier for operators to get on and off the drilling rig body 1, thus improving the convenience of using the isolation fence 4.

[0024] Furthermore, a positioning block 411 is rotatably connected to the first fence 41, and a through hole 421 is provided on the second fence 42, through which the positioning block 411 can pass. Rotating the positioning block 411 after it has passed through the through hole 421 can fix the first fence 41 and the second fence 42 together. Rotating the positioning block 411 so that it protrudes from the through hole 421 can disengage the first fence 41 from the second fence 42, thereby achieving a detachable connection between the first fence 41 and the second fence 42.

[0025] Furthermore, the through hole 421 extends in the front-to-back direction. In some embodiments, the shape of the positioning block 411 corresponds to the shape of the through hole 421. When the positioning block 411 is rotated to a horizontal state, it can pass through the through hole 421. When the positioning block 411 is rotated to a vertical state, the first fence 41 and the second fence 42 can be connected together to form a whole, ensuring the protective isolation effect.

[0026] To better achieve the rotatable connection between the second fence 42 and the lead screw 32, a connecting cylinder 321 is fixedly connected to the outer end of the lead screw 32 of the two sets of drive components 2 located at the rear side of the drilling rig body 1, and a rotating rod 422 is fixedly connected to the rear end of the second fence 42. The connecting cylinder 321 is rotatably sleeved on the outer periphery of the rotating rod 422.

[0027] Furthermore, the transmission assembly 3 also includes a mounting base 33, one side of which is fixedly connected to the drilling rig body 1. The mounting base 33 has a mounting hole 331, through which the lead screw 32 passes. The gear 31 is located outside the mounting hole 331, and the lead screw 32 is slidably connected to the mounting base 33 through the mounting hole 331. The gear 31 and the lead screw 32 are respectively installed and connected to the drilling rig body 1 through the mounting base 33. This arrangement facilitates the transmission connection between the transmission assembly 3 and the drive assembly 2.

[0028] Furthermore, the lead screw 32 is provided with a limiting groove 322, which extends in the left and right direction. A limiting block 3311 is provided in the mounting hole 331. The limiting block 3311 is fixedly connected to the mounting base 33 and slidably connected in the limiting groove 322.

[0029] Under the rotation of gear 31, the lead screw 32 rotates while being guided and limited by the cooperation between the limiting block 3311 and the limiting groove 322. Therefore, the lead screw 32 can slide along the preset direction to translate the isolation fence 4, thereby improving the stability of the opening and closing process of the isolation fence 4.

[0030] Furthermore, the drive assembly 2 also includes a connecting plate 24, one side of which is fixedly connected to the drilling rig body 1, and the connecting plate 24 protrudes from the drilling rig body 1. The hydraulic cylinder 21 is fixedly connected to the connecting plate 24, the toothed plate 23 is slidably connected to the connecting plate 24, and the support plate 22 is spaced below the connecting plate 24. This arrangement of the connecting plate 24 facilitates the layout of the drive assembly 2.

[0031] Furthermore, a telescopic rod 211 is fixedly connected to the power output end of the hydraulic cylinder 21. The telescopic rod 211 extends in the vertical direction. A connecting rod 231 is fixedly connected to the bottom of the toothed plate 23. The connecting rod 231 passes through the connecting plate 24. One end of the connecting rod 231 is fixedly connected to the telescopic rod 211. The support plate 22 is fixedly connected to the bottom end of the telescopic rod 211.

[0032] The hydraulic cylinder 21 drives the telescopic rod 211 to move linearly back and forth in the up-down direction, thereby realizing the displacement of the support plate 22 and the toothed plate 23. In some embodiments, the connecting rod 231 is arranged in an "L" shape to facilitate the fixed connection between the toothed plate 23 and the telescopic rod 211, so that the toothed plate 23 and the telescopic rod 211 can move in the same direction.

[0033] Furthermore, a limiting ring 2111 is fixedly sleeved on the outer periphery of the telescopic rod 211, and the limiting ring 2111 is located above the connection point between the connecting rod 231 and the telescopic rod 211. The limiting ring 2111 restricts the range of motion of the telescopic rod 211, preventing the telescopic rod 211 from driving the connecting rod 231 to move upward too much and causing it to collide with the hydraulic cylinder 21, thereby improving the safety of the hydraulic cylinder 21 during use and ensuring the normal use of the connecting rod 231.

[0034] Based on the disclosure and teachings of the foregoing specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this application is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this application should also fall within the protection scope of the claims of this application. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this application.
