[0001] The utility model belongs to the technical field of drilling equipment, and in particular relates to a drilling auxiliary support device for a drilling rig. Background Art

[0002] Drilling is an important means of obtaining geological information in underground projects such as tunnels and mines. When the drill rig is performing horizontal drilling construction, the front end of the drill rod will swing due to the long length of the drill rod. During operation, it is often difficult to drill holes due to the swing of the drill rod. In severe cases, the drill bit may even break, seriously affecting the drilling work.

[0003] Chinese patent CN205477393U discloses a support frame for a drill rod during drilling of a drilling rig, including a triangular support, which can initially prevent the drill rod from swinging during rotation.

[0033] Example

[0034] like Figure 1-4 As shown, a drilling auxiliary support device for a drilling rig provided in the present application includes:

[0035] Restraining mechanism, telescopic mechanism and base;

[0036] The constraint mechanism comprises a main beam 1, a fan beam 10 and a limit box 2; one end of the main beam 1 is fixedly connected to the limit box 2, and the other end is movably connected to one end of the fan beam 10, and the other end of the fan beam 10 is a free end, and a limit mechanism is provided; the limit box is provided with a notch for inserting the fan beam 10 into the limit box 2 for limit; the main beam 1 and the fan beam 10 are annular structures in the limit state;

[0037] The telescopic mechanism comprises a sleeve 4 and a screw 3 arranged therein;

[0038] The base is used to support the telescopic mechanism, and the restraint mechanism is arranged above the telescopic mechanism.

[0039] As a specific embodiment, the limiting mechanism of the fan beam 10 is a first stop tooth 12.

[0040] As a specific embodiment, the limit box 2 includes a shell and a swing block assembly and a toggle block assembly arranged therein;

[0041] The toggle block assembly includes a toggle block bracket and a toggle block 9; the toggle block bracket is a cantilever structure, the toggle block 9 is connected to the cantilever, and the cantilever is moved up and down by rotating the toggle block 9;

[0042] The swing block assembly includes a swing block, a second stop tooth 16, a connecting column 14, an elastic gasket 15 and a support seat; the swing block is connected to the inner wall of the housing through the connecting column 14, suspended above the support seat, and an elastic gasket 15 is arranged between the swing block and the support seat; the second stop tooth 16 is connected above the swing block and can be meshed with the first stop tooth 12;

[0043] One end of the swing block close to the toggle block assembly forms a movable limit with the cantilever of the toggle block assembly, the limit is released when the cantilever rises, and the limit is formed when the cantilever descends.

[0044] Specifically, the toggle block 9 is a cylinder with a connecting rod, which is connected to the toggle block bracket through the connecting rod; the toggle block bracket is a C-shaped structure.

[0045] As an improved embodiment, the toggle block extends out of the side of the shell and is provided with a protective cap on the outer surface.

[0046] As an improved embodiment, the swing block is a square block, and a baffle is provided at one end near the toggle block, and a notch is formed between the baffle and the upper end surface of the toggle block. The notch facilitates the cantilever to contact the baffle during the lifting and lowering process of the toggle block bracket cantilever, and the baffle is pressed down to make the swing block 9 drop quickly to release the limit.

[0047] As an improved embodiment, a notch for placing an elastic gasket is provided at the lower end of the swing block, and a corresponding notch is provided below the support seat. Another notch is provided below the support seat to correspond to the enclosure plate at one end of the notch at the lower end of the swing block near the toggle block 9.

[0048] As a specific embodiment, a fixing nut 8 is arranged on the screw rod 3 , and a rotating handle 7 is arranged below the fixing nut 8 .

[0049] As an improved embodiment, the rotating handle 7 is fixedly connected to the screw rod 3 and is symmetrically arranged on both sides of the screw rod 3.

[0050] As an improved embodiment, the outer wall of the rotating handle 7 is provided with anti-slip material.

[0051] As a specific embodiment, the base includes an outer long support rod 5 and an inner short support rod 6; the outer long support rod 5 is connected to the outer wall of the sleeve 4; one end of the inner short support rod 6 is connected to the outer wall of the sleeve 4, and the other end is connected to the outer long support rod 5.

[0052] Specifically, the base is composed of four groups of supporting structures which together form a stable structure to prevent the supporting device from tipping over when the drilling rig swings.

[0053] As an improved embodiment, the bottom 5 of the outer long support rod is a conical support foot, so that it can maintain stability even in bumpy lanes.

[0054] When in use, the fan beam 10 is inserted into the limit box 2, so that the first stop tooth 12 of the fan beam is meshed with the second stop tooth 16 of the swing block, thereby forming a tight constraint on the drill rod. When disassembling the support rod, the toggle block 9 is rotated to make the cantilever press down the swing block 13, release the meshing between the first stop tooth 12 and the second stop tooth 16, and at the same time pull out the fan beam 10 to release the constraint of the drilling auxiliary support device on the drill rod.

[0055] The rotating handle 7 can control the extension length of the screw rod 3. When the rotating handle 7 is rotated in the forward direction, the portion of the telescopic rod 3 extending out of the sleeve 4 becomes longer, and the constraint structure is relatively raised. When the rotating handle 7 is rotated in the reverse direction, the portion of the telescopic rod 3 extending out of the sleeve 7 becomes shorter, and the constraint structure is relatively lowered. When the constraint structure is adjusted to a suitable position, the fixing nut 8 is screwed to make the fixing nut 8 close to the rotating handle 7, so that the rotating handle 7 can be prevented from rotating, thereby preventing the drilling auxiliary support device from changing its support height when supporting for a long time.

[0056] To sum up, when in use, the drilling auxiliary support device is placed stably on the construction ground, and then the rotating handle 7 is turned to adjust the height of the support rod 3 extending out of the sleeve 4. The drill rod is placed on the limit box 2, and the fan beam 10 is inserted into the limit box 2. The annular constraint structure formed by the main beam 1 and the fan beam 10 constrains the drill rod, and a very small gap is left between the main beam 1 and the fan beam 10 and the drill rod body. Without affecting the rotation and advancement of the drill rod, the drill rod can be stabilized to the greatest extent and the swing of the drill rod can be limited. When the drilling is completed, the toggle block 9 is rotated, and the fan beam 10 is pulled out to release the restriction on the drill rod, and the drilling auxiliary support device is removed. The utility model has a simple structure and is easy to operate. It can effectively prevent the swing of the drill rod during the drilling process, thereby speeding up the operation efficiency, improving the quality of drilling, and reducing safety hazards during the operation.

[0057] The above description is only a preferred specific implementation manner of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions and improvements made by any technician familiar with the technical field within the technical scope disclosed by the present invention should be included in the scope of protection of the invention.
