Description

Technical Field

[0001] The utility model relates to the technical field of geotechnical engineering drilling equipment, in particular to an anti-deviation support for geotechnical engineering survey drilling. Background Art

[0002] Geotechnical engineering investigation refers to the activities of identifying, analyzing, evaluating the geological, environmental characteristics and geotechnical conditions of the construction site and compiling investigation documents according to the requirements of the construction project. The contents of geotechnical engineering investigation mainly include: engineering geological investigation and mapping, exploration and taking soil samples, in-situ testing, indoor testing, on-site inspection and testing. Finally, based on several or all of the above means, the site engineering geological conditions are qualitatively or quantitatively analyzed and evaluated, and the results report documents required at different stages are compiled. When conducting exploration and taking soil samples, it is necessary to drill and sample the rock and soil ground with a drilling rig;

[0003] In the prior art, for example, announcement number CN218293533U proposes an anti-deviation support for geotechnical engineering exploration and drilling. The present technical solution discloses an anti-deviation support for geotechnical engineering exploration and drilling, comprising: a limiting ring, a support leg and a level; wherein three support legs are provided, and the three support legs are distributed in a ring shape on the outer periphery of the limiting ring, and each support leg comprises a first connecting rod connected to the limiting ring, and a second connecting rod is provided at the bottom of the first connecting rod, and the first connecting rod and the second connecting rod are both hollow structures and are threadedly connected by a screw, and a support foot is also connected to the bottom of the second connecting rod, and the support foot is used to be fixed to the ground; the level is provided on the surface of the limiting ring, and a drill rod verticality adjustment structure is also provided at the bottom of the limiting ring; the present utility model solves the problem that the existing drilling support is easily affected by the flatness of the ground and affects the drilling accuracy;

[0004] However, when using the anti-deviation support for geotechnical engineering survey and drilling in the prior art solution, after fixing the device on the ground and leveling it, the drill rod is passed through the limit ring, and then the drill rod is observed to see if it is tilted. If the drill rod is found to be tilted, the verticality of the drill installed in the joint needs to be adjusted by adjusting the tightness of the bolts on the opposite side. This adjustment method is relatively cumbersome, and the staff only observes whether the drill rod is tilted by naked eyes, which is easy to cause errors, resulting in the deviation of the drill rod during use.

[0005] In order to solve the above problems, the present application proposes an anti-drifting support for geotechnical engineering survey and drilling. Utility Model Content

[0006] The utility model is intended to provide an anti-deviation support for geotechnical engineering exploration and drilling, which is mainly used to solve the problem that the existing anti-deviation support for geotechnical engineering exploration and drilling needs to adjust the verticality of the drill installed in the joint by adjusting the tightness of the bolts on the opposite side, which can easily cause the drill rod to deviate during use.

[0007] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0008] The cam is provided with a toothed plate at the bottom of the support body, and the toothed plate is provided with a toothed plate at the bottom of the support body, and the toothed plate is provided with a toothed plate at the bottom of the support body.

[0009] The working principle and beneficial effects of the utility model:

[0010] 1. Working principle: When the device is used, fix the support body on the ground and level it, then pass the drill rod through the through slot and push the slide bar to drive the moving block connected to it to move. When the moving block moves, the other moving block will move synchronously with the cooperation of the rack and the gear ring. When the two moving blocks move to make the clamping block contact the drill rod, the slide bar and the threaded barrel are fixed by the limit assembly, and then the threaded barrel can be driven to rotate by rotating the slide bar, so that the clamping block further clamps the drill rod, and then the drill rod can operate normally and perform drilling operations on rock and soil.

[0011] 2. Beneficial effect: Symmetrical moving blocks are arranged at the bottom of the support body. When the staff pushes the sliding rod, the two moving blocks will approach each other under the action of the gear ring and the rack, so that the drill rod is always in the center of the support body and in a vertical state. When the two moving blocks move to cause the clamping block to contact the drill rod, the sliding rod and the threaded barrel are fixed through the limiting assembly, and then the sliding rod is rotated to allow the clamping block to further clamp the drill rod. The advantage of this arrangement is that the clamping block can better fix the drill rod, thereby effectively ensuring the normal operation of the drill rod and further reducing the deviation of the drill rod during use.

[0012] Preferably, the limiting assembly includes an arc block fixedly connected to one end of a threaded barrel, a limiting bolt passes through the arc block, and the limiting bolt and the arc block are threadedly connected, and the outer wall of the sliding rod is provided with a groove matching the limiting bolt. When the staff pushes the sliding rod to make the clamping blocks on the two moving blocks contact the drill rod, the limiting bolt is tightened so that one end of it is pressed against the inner wall of the groove on the sliding rod, so that the sliding rod and the threaded barrel can be fixed. At this time, rotating the sliding rod again can make the clamping block further clamp the drill rod, thereby making the drilling rig more stable during operation.

[0013] Preferably, one side of the clamp block close to the gear ring is arranged in an arc shape. By setting one side of the clamp block in an arc shape, the contact surface between the clamp block and the drill rod can be larger after the clamp block clamps the drill rod, thereby making the clamp block have a better fixing effect on the drill rod and allowing the drill rod to always be in a vertical state.

[0014] Preferably, a plurality of ball bearings are rotatably connected to one side of the clamp block close to the gear ring, and the ball bearings are equidistantly distributed in a linear array on one side of the clamp block. After the clamp block clamps the drill rod, the plurality of ball bearings arranged on one side of the clamp block can effectively reduce the friction between the drill rod and the clamp block when the drill rod slides between the two clamp blocks, thereby effectively reducing the wear between the drill rod and the clamp block, thereby ensuring the accuracy of vertical adjustment and the life of the support body.

[0015] Preferably, a symmetrical guide block is fixedly connected to the inner wall of the threaded barrel, and a guide groove matching the guide block is provided on the outer wall of the slide rod. When the slide rod slides between the inner wall of the threaded barrel, the guide block provided on the inner wall of the threaded barrel and the guide groove provided on the outer wall of the slide rod can play a better limiting and guiding role for the slide rod. The advantage of such a setting is that it not only makes the sliding stability between the slide rod and the threaded barrel higher, but also makes the limiting bolt and the groove always on the same horizontal plane, thereby making the use of the device more convenient.

[0016] Preferably, there are multiple grooves, and the grooves are equidistantly distributed in a linear array on the outer wall of the slide rod. By setting the number of grooves on the slide rod to be multiple, it is not only more convenient to tighten one end of the limit bolt against the inside of the groove, but also the distance adjustment range between the two moving blocks is wider, so that the device can be suitable for drill rods of different sizes, thereby making the device more practical.

[0017] Preferably, the end of the sliding rod away from the moving block is fixedly connected to a special-shaped handle, and the outer wall of the special-shaped handle is provided with an anti-slip cover. The special-shaped handle provided at one end of the sliding rod can make it more convenient for people to turn the sliding rod. The protective cover provided on the outer wall of the special-shaped handle can effectively increase the friction between people's hands and the special-shaped handle, preventing people from slipping when turning the special-shaped handle.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4 A support for preventing deviation from rock and soil engineering exploration and drilling comprises a support body 1, a through slot 2 being opened at the center of the top of the support body 1. After the staff fixes the support body 1 on the ground and levels it, the drill rod passes through the through slot 2. The bottom of the support body 1 is slidably connected with symmetrical moving blocks 3, and the moving blocks 3 are located on both sides of the through slot 2. A gear ring 4 is rotatably connected at the center of the bottom of the support body 1, and racks 5 are meshedly connected on both sides of the gear ring 4. The rack 5 is slidably connected to the support body 1, and the rack 5 and the support body 1 are slidably connected through a slide rail structure.

[0025] The ends of the two racks 5 away from the gear ring 4 are fixedly connected to the moving blocks 3 respectively. By pushing one of the moving blocks 3, the two moving blocks 3 can be brought close to each other under the action of the gear ring 4 and the rack 5. The moving blocks 3 are fixedly connected to the side of the through groove 2. When the moving blocks 3 move, the clamping blocks 6 are driven to move and clamp the drill rod. The side of the clamping block 6 close to the gear ring 4 is arranged in an arc shape, which can make the contact surface between the clamping block 6 and the drill rod larger after the drill rod is clamped, so that the clamping block 6 has a better fixing effect on the drill rod; the side of the clamping block 6 close to the gear ring 4 is rotatably connected to a plurality of ball bearings 15, and the ball bearings 15 are equidistantly distributed on one side of the clamping block 6 in a linear array, so that when the drill rod slides between the two clamping blocks 6, the friction between the drill rod and the clamping block 6 can be effectively reduced, thereby effectively reducing the wear between the drill rod and the clamping block 6, thereby ensuring the accuracy of vertical adjustment and the life of the support body 1.

[0026] The bottom of the support body 1 is fixedly connected to one side of one of the moving blocks 3, and a fixed block 7 is fixedly connected. A threaded barrel 8 runs through the fixed block 7, and the threaded barrel 8 is threadedly connected to the fixed block 7. A sliding rod 9 runs through the inside of the threaded barrel 8, and the sliding rod 9 is slidably connected to the inner wall of the threaded barrel 8. Figure 4 As shown, the inner wall of the threaded barrel 8 is fixedly connected with a symmetrical guide block 13, the outer wall of the slide rod 9 is provided with a guide groove 14 matching the guide block 13, one end of the slide rod 9 is rotatably connected with the moving block 3, the end of the slide rod 9 away from the moving block 3 is fixedly connected with a special-shaped handle 16, and the outer wall of the special-shaped handle 16 is provided with an anti-slip sleeve, one end of the threaded barrel 8 is fixedly connected with a limiting assembly, and the two moving blocks 3 can be brought close to each other by pushing the slide rod 9. When the two moving blocks 3 move to cause the clamping block 6 to contact the drill rod, the slide rod 9 and the threaded barrel 8 are fixed by the limiting assembly, and then the slide rod 9 is rotated to make the clamping block 6 further clamp the drill rod, and then the drill rod can operate normally and perform drilling operations on rock and soil.

[0027] like Figure 2 and Figure 4 As shown, the limiting assembly includes an arc block 10 fixedly connected to one end of a threaded tube 8, a limiting bolt 11 passes through the arc block 10, and the limiting bolt 11 is threadedly connected to the arc block 10, and the outer wall of the slide rod 9 is provided with a groove 12 matching the limiting bolt 11, and the number of the grooves 12 is multiple, and the grooves 12 are evenly distributed on the outer wall of the slide rod 9 in a linear array. When the staff pushes the slide rod 9 to make the clamping blocks 6 on the two moving blocks 3 contact the drill pipe, tighten the limiting bolt 11 so that one end of it is pressed against the inner wall of the groove 12 on the slide rod 9, so that the slide rod 9 and the threaded tube 8 can be fixed. At this time, rotating the slide rod 9 again can make the clamping block 6 further clamp the drill pipe, thereby making the drilling rig more stable during operation.

[0028] From the above, it can be seen that the specific implementation of the utility model is as follows:

[0029] When the device is in use, after the support body 1 is fixed on the ground and leveled, the drill rod is passed through the through groove 2, and the slide bar 9 is pushed, which can drive the moving block 3 connected to it for rotation to move. While the moving block 3 moves, the other moving block 3 will move synchronously with the cooperation of the rack 5 and the gear ring 4. When the two moving blocks 3 move to cause the clamping block 6 to contact the drill rod, tighten the limit bolt 11 so that one end of it is pressed against the inner wall of the groove 12 on the slide bar 9, so that the slide bar 9 and the threaded tube 8 can be fixed, and then the special-shaped handle 16 can be turned to make the slide bar 9 drive the threaded tube 8 to rotate, so that the clamping block 6 further clamps the drill rod, and the drilling rig can operate normally and perform drilling operations on rock and soil.

[0030] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
