Description

Technical Field

[0001] The invention relates to the technical field of ground stress meter installation, and in particular to an auxiliary installation device for a mining ground stress meter. Background Art

[0002] A mining in-situ stress meter is an instrument specifically used to measure stress distribution in underground rocks. It is mainly used in mining engineering, geological exploration and other fields. The in-situ stress meter can provide information about the internal stress state of underground rocks, which is essential for evaluating the safety and stability of mines and guiding reasonable mining plans. When the in-situ stress meter is installed in a borehole, a in-situ stress test installation device is usually used. However, the existing in-situ stress test installation equipment usually has problems such as low installation accuracy and installation rod offset, which affects the accuracy of stress distribution measurement in underground rocks.

[0003] Therefore, an auxiliary installation device for a mine-used ground stress meter has been developed, which can prevent the installation rod from deviating and ensure that the installation rod is always located at the axial center position of the borehole. Summary of the invention

[0004] In order to overcome the shortcomings of existing ground stress test installation equipment, which usually have problems such as low installation accuracy and installation rod offset, which affect the accuracy of stress distribution measurement in underground rocks, the present invention provides an auxiliary installation device for a mining ground stress meter that can prevent the installation rod from offsetting and ensure that the installation rod is always located at the axial center position of the drill hole.

[0005] The technical solution of the present invention is: an auxiliary installation device for a mining ground stress meter, including a mounting rod, a support tube and an anti-deviation mechanism. The outer side of the mounting rod is slidably and detachably connected to the support tube, and the support tube is provided with an anti-deviation mechanism that can prevent the mounting rod from shifting.

[0006] In one embodiment, both the left and right parts of the mounting rod are provided with threads.

[0007] In one embodiment, the anti-deviation mechanism includes a rotating ring, a threaded tube, a threaded sleeve, a connecting rod, a rotating arm and a contact wheel. The threaded tube is rotatably connected to the outer side of the support tube, the rotating ring is connected to the middle of the threaded tube, and the left and right threaded sleeves are threadedly connected to the middle of the threaded tube. The rotating ring is located between the threaded sleeves. The threaded sleeves are rotatably connected to multiple connecting rods, and the connecting rods are rotatably connected to rotating arms. The rotating arms are rotatably connected to the support tube, and the contact wheels are rotatably connected on the sides of the rotating arms that are close to each other. The rotating ring is rotated to drive the threaded tube to rotate, so that the threaded sleeves move away from each other, and the connecting rod rotates to rotate the rotating arms to rotate and open, thereby opening the contact wheel to adapt to the aperture of the borehole. After adjustment, the mounting rod is sent into the borehole so that the contact wheel contacts the inner wall of the borehole and moves on the inner wall of the borehole until the hollow inclusion stress meter is sent into the test circular hole in the borehole.

[0008] In one embodiment, a handle is provided on the rotating ring.

[0009] In one of the embodiments, a reinforcement mechanism is also included, which includes a piston rod, a piston cylinder and an airbag. Multiple piston rods are connected to the outside of the threaded sleeve, and piston cylinders are slidably connected to the piston rods. The piston cylinders are connected to support tubes, and the inner sides of the left and right parts of the support tubes are connected to airbags. The piston cylinders are connected to adjacent airbags. When the threaded sleeves move away from each other, they drive the piston rods to move away from each other, so that the piston rods move in the piston cylinder, pushing the gas in the piston cylinder into the airbag, causing the airbag to expand and contact the two sections of the mounting rod respectively.

[0010] In one of the embodiments, an anti-rotation mechanism is also included, which includes a support arm, a sliding frame, a guide frame and a spring. A plurality of support arms are connected to the left and right sides of the support tube. The support arms are slidably connected to the sliding frames. The sliding frames are movably connected to adjacent contact wheels. The sliding frames are slidably connected to the guide frames. Springs are connected between the guide frames and the connected sliding frames. When the mounting rod is sent into the borehole, the guide frame contacts the inner wall of the borehole and moves along the inner wall of the borehole. After the guide frame contacts the inner wall of the borehole, it moves downward relative to the support arm. While the contact wheel rotates and opens outward, it drives the sliding frame to move on the support arm. The sliding frame maintains a relative position through the action of the spring, thereby allowing the contact wheel to maintain a relative position.

[0011] In one of the embodiments, a locking mechanism is also included, which includes a support block, an adjusting screw and a connecting ring. The support block is connected to the front side of the right part of the support tube, the adjusting screw is threadedly connected to the support block, and the connecting ring is connected to the outer side of the right part of the threaded tube. After the threaded tube stops rotating, the adjusting screw is rotated to move the adjusting screw to contact the connecting ring.

[0012] In one of the embodiments, an anti-backward mechanism is also included, which includes a connecting plate, an electric push rod and a reinforcement strip. The rotating arm is connected to the connecting plate, the connecting plate is connected to the electric push rod, and the telescopic end of the electric push rod is connected to the reinforcement strip. The electric push rod on the connecting plate is started to push the reinforcement strip to move to the contact wheel to limit the contact wheel.

[0013] In one embodiment, anti-slip pads are provided on the reinforcement strips.

[0014] In one of the embodiments, an obstacle clearing mechanism is also included, which includes a support sleeve, a rotating plate and a torsion spring. The support sleeve is connected to the guide frame, and the rotating plate is rotatably connected to the support sleeve. A plurality of torsion springs are connected between the rotating plates and the connected support sleeves. When the guide frame contacts the inner wall of the borehole, the force of the torsion spring causes the rotating plate to cling to the inner wall of the borehole and move on the inner wall of the borehole accordingly.

[0015] Beneficial effects: 1. The present invention rotates the rotating ring to drive the threaded tube to rotate, so that the threaded sleeves move away from each other, and the connecting rod rotates to make the rotating arm rotate and open. After adjustment, the installation rod is sent into the drill hole, so that the contact wheel contacts the inner wall of the drill hole and moves on the inner wall of the drill hole, thereby preventing the installation rod from deviating and ensuring that the installation rod is always located at the axial center position of the drill hole.

[0016] 2. The present invention drives the piston rod to move away from each other while the threaded sleeves move away from each other, so that the piston rod moves in the piston cylinder, pushing the gas in the piston cylinder into the airbag, causing the airbag to expand and contact the two sections of the mounting rod respectively, thereby achieving the effect of fixing the support tube on the mounting rod and enhancing the connection stability between the support tubes.

[0017] 3. When the mounting rod is inserted into the borehole, the guide frame is brought into contact with the inner wall of the borehole by the action of the spring and moves along the inner wall of the borehole, thereby guiding the support tube and preventing the support tube from rotating.

[0018] 4. The present invention drives the sliding frame to move on the support arm while the contact wheel rotates and opens outwards. The sliding frame is kept in a relative position by the action of the spring, and the contact wheel is kept in a relative position, thereby achieving the effect of limiting the contact wheel and improving the stability of the contact wheel.

[0019] 5. The present invention achieves the effect of locking the threaded tube and preventing the threaded tube from rotating and affecting the stability of the contact wheel by rotating the adjusting screw after the threaded tube stops rotating, so that the adjusting screw moves to contact the connecting ring.

[0020] 6. When the drilling angle is inclined and the epoxy adhesive consolidator mixed solution in the hollow inclusion stress measuring meter is squeezed into the test circular hole and needs to stay for a period of time, the electric push rod on the connecting piece is started to push the reinforcement bar to move to the contact wheel and limit the contact wheel, thereby achieving the effect of locking the contact wheel and preventing the contact wheel from rotating and causing the device to exit the drilling hole.

[0021] 7. When the guide frame of the present invention contacts the inner wall of the borehole, the force of the torsion spring causes the rotating plate to cling to the inner wall of the borehole and move along the inner wall of the borehole, thereby removing obstacles in the borehole and preventing the contact wheel from deviating due to encountering obstacles.

DETAILED DESCRIPTION

[0033] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, but the protection scope and application scope of the present invention are not limited.

[0034] A mine-use ground stress meter auxiliary installation device, such as Figure 1 and Figure 2 As shown, it includes a mounting rod 1, a support tube 2 and an anti-deviation mechanism 3. The outer side of the mounting rod 1 is slidably and detachably connected to the support tube 2. Both the left and right parts of the mounting rod 1 are provided with threads for easy splicing. The support tube 2 is provided with an anti-deviation mechanism 3.

[0035] like Figure 1 and Figure 3As shown, the anti-deviation mechanism 3 includes a rotating ring 31, a threaded tube 32, a threaded sleeve 33, a connecting rod 34, a rotating arm 35 and a contact wheel 36. The threaded tube 32 is rotatably connected to the outer side of the support tube 2, and the rotating ring 31 is connected to the middle of the threaded tube 32. A handle is provided on the rotating ring 31 for easy grasping and rotation. The middle of the threaded tube 32 is threadedly connected to two left and right threaded sleeves 33, and the rotating ring 31 is located between the threaded sleeves 33. Three connecting rods 34 are rotatably connected to the threaded sleeves 33, and the connecting rods 34 are rotatably connected to the rotating arms 35. The rotating arms 35 are all rotatably connected to the support tube 2, and the contact wheels 36 are rotatably connected to the sides of the rotating arms 35 that are close to each other.

[0036] When using the present invention, firstly, the hollow inclusion stress meter is installed on the installation rod 1, and then, according to the depth of the borehole, a corresponding number of installation rods 1 are spliced ​​to adapt to the depth of different boreholes, and then the support tube 2 is sleeved between the outsides of two adjacent installation rods 1, and then according to the aperture of the borehole, the rotating ring 31 is rotated to drive the threaded tube 32 to rotate, so that the threaded sleeve 33 moves away from each other, and the connecting rod 34 rotates to rotate and open the rotating arm 35, so that the contact wheel 36 opens and adapts to the aperture of the borehole. After adjustment, the installation rod 1 is sent into the borehole, so that the contact wheel 36 contacts the inner wall of the borehole and moves on the inner wall of the borehole until the hollow inclusion stress meter is sent into the test circular hole in the borehole, so that the epoxy adhesive consolidator mixed solution in the hollow inclusion stress meter is squeezed into the test circular hole, so that the epoxy adhesive consolidator makes the hollow inclusion stress meter in close contact with the surrounding rock or concrete to ensure sealing. This can prevent the installation rod 1 from deviating and ensure that the installation rod 1 is always located at the axial center of the drilling hole.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, a reinforcement mechanism 4 is also included, and the reinforcement mechanism 4 includes a piston rod 41, a piston cylinder 42 and an air bag 43. Three piston rods 41 are connected to the outside of the threaded sleeve 33, and piston cylinders 42 are slidably connected to the piston rods 41. The piston cylinders 42 are connected to the support tube 2. The inner sides of the left and right parts of the support tube 2 are connected to the air bags 43, and the piston cylinders 42 are connected to the adjacent air bags 43.

[0038] By using the reinforcement mechanism 4 of the device, the support tube 2 can be reinforced. When the threaded sleeves 33 move away from each other, the piston rods 41 are driven to move away from each other, so that the piston rods 41 move in the piston cylinder 42, and the gas in the piston cylinder 42 is pushed into the airbag 43, so that the airbag 43 expands and contacts with the two sections of the mounting rod 1 respectively, thereby fixing the support tube 2 on the mounting rod 1 and enhancing the connection stability between the support tubes 2.

[0039] like Figure 1 , Figure 6 and Figure 7 As shown, an anti-rotation mechanism 5 is also included, and the anti-rotation mechanism 5 includes a support arm 51, a sliding frame 52, a guide frame 53 and a spring 54. Three support arms 51 are connected to the left and right sides of the support tube 2. The support arms 51 are slidably connected to the sliding frames 52. The sliding frames 52 are movably connected to the adjacent contact wheels 36. The sliding frames 52 are slidably connected to the guide frames 53. The guide frames 53 are connected to the connected sliding frames 52 with springs 54.

[0040] The anti-rotation mechanism 5 of the device can prevent the support tube 2 from rotating and limit the contact wheel 36. When the mounting rod 1 is inserted into the borehole, the guide frame 53 is brought into contact with the inner wall of the borehole by the action of the spring 54 and moves along the inner wall of the borehole, thereby guiding the support tube 2 to prevent the support tube 2 from rotating. After the guide frame 53 contacts the inner wall of the borehole, it moves downward relative to the support arm 51. While the contact wheel 36 rotates and opens outward, it drives the sliding frame 52 to move on the support arm 51. The action of the spring 54 keeps the sliding frame 52 in a relative position, thereby keeping the contact wheel 36 in a relative position, thereby limiting the contact wheel 36 and improving the stability of the contact wheel 36.

[0041] like Figure 1 and Figure 8 As shown, a locking mechanism 6 is also included, which includes a support block 61, an adjusting screw 62 and a connecting ring 63. The support block 61 is connected to the front right side of the support tube 2, the adjusting screw 62 is threadedly connected to the support block 61, and the connecting ring 63 is connected to the outer right side of the threaded tube 32.

[0042] The locking mechanism 6 of the device can be used to lock the threaded tube 32. After the threaded tube 32 stops rotating, the adjusting screw 62 is rotated to move the adjusting screw 62 to contact the connecting ring 63, thereby locking the threaded tube 32 and preventing the rotation of the threaded tube 32 from affecting the stability of the contact wheel 36.

[0043] like Figure 1 and Fig. 9 As shown, an anti-retreat mechanism 7 is also included, and the anti-retreat mechanism 7 includes a connecting piece 71, an electric push rod 72 and a reinforcement strip 73. The rotating arm 35 is connected to the connecting piece 71, the connecting piece 71 is connected to the electric push rod 72, and the telescopic end of the electric push rod 72 is connected to the reinforcement strip 73. The reinforcement strip 73 is provided with an anti-slip pad to facilitate fixing the contact wheel 36.

[0044] The anti-retraction mechanism 7 of the device can prevent the installation rod 1 from withdrawing from the drill hole. When the drilling angle is inclined, the epoxy adhesive consolidating agent mixed solution in the hollow core stress measuring instrument is squeezed into the test circular hole and needs to stay for a period of time, the electric push rod 72 on the connecting piece 71 is started to push the reinforcement bar 73 to move to the contact wheel 36 to limit the contact wheel 36, thereby locking the contact wheel 36 and preventing the contact wheel 36 from rotating and causing the device to withdraw from the drill hole.

[0045] like Figure 1 and Fig.10 As shown, an obstacle clearing mechanism 8 is also included, which includes a support sleeve 81, a rotating plate 82 and a torsion spring 83. The guide frame 53 is connected to the support sleeve 81, and the support sleeve 81 is rotatably connected to the rotating plate 82. Two torsion springs 83 are connected between the rotating plate 82 and the connected support sleeve 81.

[0046] By using the obstacle removal mechanism 8 of the present device, obstacles in the borehole can be removed. When the guide frame 53 contacts the inner wall of the borehole, the force of the torsion spring 83 causes the rotating plate 82 to cling to the inner wall of the borehole and move along the inner wall of the borehole, thereby removing obstacles in the borehole and preventing the contact wheel 36 from deviating due to encountering obstacles.

[0047] The above description is only an example of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention should be included in the protection scope of the present invention. The contents not elaborated in detail in the present invention belong to the existing technologies known to those skilled in the art.
