Description

Technical Field

[0001] The utility model relates to the technical field of engineering investigation, and particularly relates to a drilling deviation prevention device for engineering investigation. Background Technique

[0002] In the field of engineering construction, engineering investigation is a crucial preliminary link. By means of drilling, information such as the physical and mechanical properties of underground rock and soil and the stratum structure is obtained, providing a reliable basis for engineering design and construction. Accurate drilling results can ensure the safety, stability and economy of the project.

[0003] According to a drilling deviation prevention device for engineering investigation (authorization announcement number: CN221546858U) disclosed on the patent network, it is described that "the utility model specifically relates to the field of drilling equipment, and discloses a drilling deviation prevention device for engineering investigation, including a main support frame and two sub-support frames. A fixed plate is fixedly connected to the bottom end of the main support frame, and an electric push rod two is fixedly connected to the bottom end of the fixed plate. A total of three rollers are arranged at the output end of the bottom end of the electric push rod two and the bottom end of the main support frame. By setting sub-support frames, electric push rod one, support seats and limit seats, the two limit seats are both U-shaped and symmetrically distributed. The limit seats form a 90-degree angle with the main support frame, which can limit the rotation angle of the sub-support frames, thereby improving the convenience of angle adjustment of the sub-support frames to support and limit the sub-support frames. Both are L-shaped. By starting the electric push rod one, the support seat can be driven to move downward, so that the support seat is inserted into the ground, thereby restricting the rolling of the rollers, and thus improving the stability of the support of the main support frame."

[0004] In view of the above description, the applicant believes that the following problems exist:

[0005] During the use of this utility model, on the one hand, the structure of the device is relatively fixed and fine-tuning operations cannot be performed during actual operation. For example, when encountering slight changes in terrain or small deviations during the drilling process, it is difficult to precisely adjust the device, which may lead to large deviations in the drilling direction and affect the accuracy of the investigation results. At the same time, since different engineering investigation projects may use drilling rods of different diameters, it is difficult for this device to adapt to drilling rods of different sizes by sleeving the drilling rods with collars. This reduces the versatility and applicability of the device. On the other hand, the sub-support frame of this device is stored by a claw, and the claw is made of rubber material, which may age or deform over time and with the number of uses.

[0028] Embodiment 1:

[0029] Please refer to Figures 1-4, the present utility model provides a technical solution: including a workbench 1 and a drilling motor 2. The output end of the drilling motor 2 is fixedly connected with a drilling rod 3. A fixing plate 4 is arranged on the surface of the drilling rod 3. A reset spring 5 is fixedly connected between the bottom of the drilling motor 2 and the fixing plate 4. Fixed blocks 6 are fixedly connected to both sides of the workbench 1. An adjusting mechanism 7 is arranged inside the workbench 1. Fixed rod storage mechanisms 8 are arranged on both sides of the workbench 1. Four telescopic universal wheels 9 are fixedly connected to the bottom of the workbench 1;

[0030] The adjusting mechanism 7 includes a distance fine-tuning component 71 and a size adjusting component 72. The distance fine-tuning component 71 is arranged outside the fixing plate 4 and extends into the workbench 1. The size adjusting component 72 is arranged inside the workbench 1.

[0031] Furthermore, the distance fine-tuning component 71 includes an adjusting motor 711. The adjusting motor 711 is fixedly installed on the back of the workbench 1. The output end of the adjusting motor 711 is fixedly installed with a first bevel gear 712. Two first connecting rods 713 are rotatably connected inside the back of the workbench 1. Second bevel gears 714 are fixedly connected to both the left and right ends of the first connecting rod 713. Spiral rods 715 are rotatably connected inside both the left and right sides of the workbench 1. A third bevel gear 716 is fixedly connected to one end of the spiral rod 715 close to the second bevel gear 714. A first fixing bracket 717 is threadedly connected to the surface of the spiral rod 715. A first fixing bolt 718 is threadedly connected inside the fixing plate 4. A second connecting rod 719 is rotatably connected inside the back of the workbench 1. Fourth bevel gears 7110 are fixedly connected to both the top and bottom of the second connecting rod 719. By setting the distance fine-tuning component 71, the workbench 1 can also perform fine-tuning operations after being fixed.

[0032] Furthermore, there are two sets of the distance fine-tuning component 71, which are respectively arranged at the top of the workbench 1 and the center of the workbench 1. The fixing plate 4 is slidably connected inside the chute opened inside the first fixing bracket 717. The first bevel gear 712, the second bevel gear 714 inside the first connecting rod 713, and the fourth bevel gear 7110 at the top of the second connecting rod 719 are meshed with each other. The second bevel gear 714 outside the first connecting rod 713 and the third bevel gear 716 are meshed with each other. Due to the meshing relationship between the first bevel gear 712 and the second bevel gear 714, the first connecting rod 713 can be rotated. The second bevel gear 714 is also meshed with the third bevel gear 716, so that the fixing bracket 717 threadedly connected to the surface of the spiral rod 715 can move back and forth. Due to the meshing relationship between the first bevel gear 712 and the fourth bevel gear 7110, the fixing bracket 717 arranged at the center of the workbench 1 can move back and forth synchronously.

[0033] Further, the size adjustment component 72 includes a size adjustment plate 721. The size adjustment plate 721 is slidably connected to a chute formed inside a fixing bracket 717 provided at the center of the workbench 1. A rotating plate 722 is rotatably connected inside the size adjustment plate 721. A size adjustment block 723 is slidably connected inside the rotating plate 722. Second fixing bolts 724 are threadedly connected to both sides of the size adjustment plate 721. When the rotating plate 722 is rotated, it will drive the size adjustment block 723 to rotate along a groove formed inside the rotating plate 722. After adjusting to a suitable position, the drilling rod 3 can be prevented from shifting during the drilling process.

[0034] Further, grooves are formed on the inner bottom wall of the size adjustment plate 721 and the bottom of the rotating plate 722, and the grooves and the corresponding protrusions are meshed with each other. When the rotating plate 722 is fixed, the size adjustment block 723 will not rotate.

[0035] Embodiment 2:

[0036] Please refer to Figures 5-6 and in combination with Embodiment 1, it is further obtained that the fixed rod storage mechanism 8 includes a fixed telescopic rod 81. The fixed telescopic rod 81 is rotatably connected inside the fixed block 6. Clamping fixing platforms 82 are provided inside the fixed legs on both the left and right sides of the workbench 1. A clamping cylinder 83 is fixedly connected to the back of the clamping fixing platform 82. A clamping push block 84 is fixedly connected to the output end of the clamping cylinder 83. A clamping jaw 85 is slidably connected inside the clamping fixing platform 82. When the device is not in use, the clamping jaw 85 can clamp the fixed telescopic rod 81 to prevent the fixed telescopic rod 81 from shaking during movement.

[0037] Further, a chute is formed inside the clamping jaw 85, and the clamping push block 84 is slidably connected inside the chute. When the clamping cylinder 83 is opened, it will drive the clamping push block 84 to move forward, thereby opening the clamping jaw 85. When the clamping cylinder 83 is closed, the clamping push block 84 can be driven to move backward, thereby closing the clamping jaw 85 and completing the storage work of the clamping jaw 85.

[0038] During the actual operation process, when this device is in use, it is necessary to lift the rotating plate 722 according to the size of the drilling rod 3. Rotating the rotating plate 722 will drive the size adjusting block 723 to rotate along the groove opened inside the rotating plate 722. After adjusting to a suitable position, lower the rotating plate 722. The convex block at the bottom of the rotating plate 722 will engage with the groove opened on the inner wall of the bottom of the size adjusting plate 721 to fix the rotating plate 722, so that the size adjusting block 723 will not rotate, which can prevent the drilling rod 3 from shifting during the drilling process. Then, turn on the clamping cylinder 83, which will drive the clamping push block 84 to move forward, thereby opening the clamping jaws 85. Then, rotate and fix the telescopic rod 81 to a suitable position, fix the workbench 1, and adjust the telescopic universal wheel 9 to make the workbench 1 in a horizontal state. Start the drilling motor 2, and the drilling rod 3 descends to the drilling position to survey the soil quality. When it is necessary to finely adjust the position of the drilling rod 3, start the adjusting motor 711. Due to the meshing relationship between the first bevel gear 712 and the second bevel gear 714, the first connecting rod 713 can be rotated. The second bevel gear 714 meshes with the third bevel gear 716, which can drive the fixing frame 717 threadedly connected to the surface of the screw rod 715 to move back and forth. Due to the meshing relationship between the first bevel gear 712 and the fourth bevel gear 7110, the fixing frame 717 provided at the center of the workbench 1 can be driven to move back and forth synchronously. When it is necessary to adjust the left and right positions, loosen the first fixing bolt 718 and the second fixing bolt 724, and then the left and right positions of the fixing plate 4 and the size adjusting plate 721 can be adjusted. After adjusting to the required position, tighten the first fixing bolt 718 and the second fixing bolt 724 to complete the fine adjustment operation. When the drilling work is completed, the return spring 5 can accelerate the reset of the drilling rod 3. Then, reset and rotate the fixed telescopic rod 81 into the clamping jaws 85, and turn on the clamping cylinder 83 to complete the storage work of the clamping jaws 85.
