Description

Technical Field

[0001] This invention relates to the field of anchor bolt construction technology, specifically a tool for measuring the drilling angle of anchor bolts in dangerous rock formations. Background Technology

[0002] In the construction of unstable rock formations, anchor bolts, through their unique mechanical action and structural function, have become the core measure for reinforcing unstable rock masses and preventing disasters. During the construction process, anchor bolts are usually tilted at a preset angle according to construction requirements before being inserted into the rock strata. In order to ensure that the drilling angle of the anchor bolts meets the design and construction requirements, it is necessary to measure the drilling angle of the anchor bolts.

[0003] CN215810623U discloses a tool for measuring the drilling angle of anchor bolts, including a metal base plate, a flat plate, and a protrusion on the upper surface of one end of the flat plate. The upper surface of the flat plate is provided with a magnet receiving groove, in which a magnet is placed. A rotating shaft is fixedly installed on one side of the protrusion, and the axis of the rotating shaft is parallel to the flat plate. When the base plate is placed on the drilling platform of a drilling machine, since the magnet is placed in the magnet receiving groove and the base plate is made of metal, and the drilling platform is also made of metal, the base plate can be magnetically attracted to the drilling platform. With the cooperation of components such as an adjustment plate, the angle measurement effect can be achieved.

[0004] This technical solution only uses magnetic attraction to fix components such as the base plate. However, the environment during construction on dangerous rocks is complex, and the vibration of the anchor drilling machine during operation can easily affect the magnetic attraction effect. If dust, debris or foreign objects accumulate on the magnetic attraction components, it will hinder close contact and reduce the attraction force. Therefore, the overall stability and practicality are poor. Summary of the Invention

[0005] The present invention aims to provide a tool for measuring the drilling angle of rock anchor bolts, which has the characteristics of accurate measurement, good stability and high practicality.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tool for measuring the drilling angle of rock anchor bolts, comprising a drill arm, an assembly plate provided on the lower side of the drill arm, rectangular holes provided on both the left and right sides of the assembly plate, clamping plates slidably connected to the rectangular holes, a bidirectional screw provided on the lower side of the assembly plate, the two sides of the bidirectional screw being slidably connected to the lower side of the clamping plates, connecting blocks provided on both the front and rear sides of the clamping plates, a magnetic block connected to the front side of the connecting blocks, a first T-slot provided on the assembly plate, and the lower side of the clamping plates being slidably connected to the first T-slot;

[0007] A connecting plate is provided on one side of the assembly plate, and an insert block corresponding to the first T-slot is provided on one side of the connecting plate. An angle plate is provided on the connecting plate, and a fixed shaft is provided on one side of the angle plate. A rotating component is sleeved on the fixed shaft, and an external thread is provided on the fixed shaft. A fastening knob is threadedly connected to the fixed shaft.

[0008] The lower side of the assembly plate is connected to a U-shaped assembly frame by screws. A snap-fit ​​component is provided on one side of the U-shaped assembly frame. A second T-slot is provided on both sides of the assembly plate. The lower side of the connecting block is slidably connected to the second T-slot. A first fastening bolt is threadedly connected to the lower side of the connecting block.

[0009] In the above scheme: the rotating assembly includes a rotating block, one side of which is rotatably connected to the fixed shaft, an observation hole is provided on the rotating block, a pointer is provided on the inner wall of one side of the observation hole, and an observation element is inserted into the front side of the observation hole;

[0010] The observation component includes a U-shaped component. Positioning grooves are provided on both the upper and lower sides of the observation hole. Positioning blocks corresponding to the positioning grooves are provided on the U-shaped component. Threaded holes are provided on both sides of the observation hole. Connecting bolts corresponding to the threaded holes are inserted into both sides of the U-shaped component. A magnifying glass is embedded in the middle part of the U-shaped component.

[0011] The rotating block has a third T-shaped groove on its upper side, and a connecting seat is slidably connected to the third T-shaped groove. A level is provided on the upper side of the connecting seat.

[0012] In the above scheme: the snap-fit ​​assembly includes a housing disposed on the lower side of the U-shaped assembly frame, a strip block is inserted into one side of the housing, the inner wall of the housing is connected to one side of the strip block through a spring rod, a translation block is connected to the other side of the strip block, and an insert is provided on the upper side of the translation block.

[0013] In the above scheme: the other side of the connecting plate is provided with a strip-shaped hole corresponding to the insert.

[0014] In the above scheme: an elastic rubber block is provided on the inner side of the clamping piece.

[0015] In the above scheme: a second fastening bolt is threadedly connected to one side of the rotating block.

[0016] In the above scheme: a lighting lamp is provided on the inner wall of the other side of the observation hole.

[0017] In the above scheme: a handwheel is provided on one side of the bidirectional screw.

[0018] In the above scheme: the upper side of the insert block is threaded with a third fastening bolt.

[0019] The beneficial effects of this invention are:

[0020] 1. Through the synergistic effect of multiple structures, the stability in complex construction environments is significantly enhanced. By cooperating with components such as bidirectional screws and magnetic blocks, the tool can be firmly fixed to the drill arm of the anchor drilling rig. An elastic rubber block is set on the inner side of the clamping plate. Utilizing its soft and elastic properties, the impact of drilling vibration on the measurement is reduced. Compared with the existing technology that relies solely on magnetic fixation, it overcomes the problem of decreased adsorption force caused by complex environments, drilling vibration, and dust accumulation on magnetic components. It can maintain stable measurement under the harsh conditions of construction on dangerous rock, greatly improving the accuracy and reliability of the measurement.

[0021] 2. The rotating block in the rotating assembly can rotate flexibly around the fixed axis. The pointer set on the inner wall of one side of the observation hole can accurately indicate the scale on the angle plate, making it convenient for construction personnel to read angle data. In addition, the magnifying glass in the observation piece can magnify the pointer and scale, making the data reading clearer and more accurate, effectively avoiding reading errors caused by small viewing angle or scale.

[0022] 3. Adopting a modular design concept, the various components are flexibly connected and easy to disassemble and assemble. In different construction scenarios, components can be quickly adjusted and replaced according to actual needs, improving the versatility and practicality of the tool. Attached Figure Description

Connecting blocks 5 are provided on both the front and rear sides of the clamping plate 3. A magnetic block 6 is connected to the front side of the connecting block 5. A first T-slot 7 is provided on the assembly plate 2. The lower side of the clamping plate 3 is slidably connected to the first T-slot 7.

[0036] A connecting plate 8 is provided on one side of the assembly plate 2, and a plug 9 corresponding to the first T-slot 7 is provided on one side of the connecting plate 8. An angle plate 10 is provided on the connecting plate 8, and a fixed shaft 11 is provided on one side of the angle plate 10. A rotating component is sleeved on the fixed shaft 11, and an external thread is provided on the fixed shaft 11. A fastening knob 12 is threadedly connected to the fixed shaft 11.

[0037] A U-shaped assembly frame 13 is connected to the lower side of the assembly plate 2 by screws. A snap-fit ​​component is provided on one side of the U-shaped assembly frame 13. A second T-slot 14 is provided on both sides of the assembly plate 2. The lower side of the connecting block 5 is slidably connected to the second T-slot 14. A first fastening bolt 15 is threadedly connected to the lower side of the connecting block 5.

[0038] The rotating assembly includes a rotating block 16, one side of which is rotatably connected to a fixed shaft 11. An observation hole 17 is provided on the rotating block 16, and a pointer 18 is provided on the inner wall of one side of the observation hole 17. An observation element is inserted into the front side of the observation hole 17.

[0039] The observation component includes a U-shaped component 19. The observation hole 17 has positioning grooves on both the upper and lower sides. The U-shaped component 19 is provided with positioning blocks corresponding to the positioning grooves. The observation hole 17 has threaded holes on both sides. The U-shaped component 19 is connected with connecting bolts 20 corresponding to the threaded holes on both sides. The middle part of the U-shaped component 19 is fitted with a magnifying glass 21.

[0040] A third T-slot 22 is provided on the upper side of the rotating block 16. A connecting seat 23 is slidably connected to the third T-slot 22. A level 24 is provided on the upper side of the connecting seat 23.

[0041] The snap-fit ​​assembly includes a housing 25 disposed on the lower side of the U-shaped assembly frame 13. A strip block 26 is inserted into one side of the housing 25. The inner wall of the housing 25 is connected to one side of the strip block 26 through a spring rod. A translation block 27 is connected to the other side of the strip block 26. An insert 28 is disposed on the upper side of the translation block 27.

[0042] It should be noted that in the construction of unstable rock formations, anchor bolts, through their unique mechanical action and structural function, become the core measure for reinforcing unstable rock masses and preventing disasters. During the anchor bolt construction process, the anchor bolts are usually tilted at a preset angle according to construction requirements before being inserted into the rock strata. In order to ensure that the drilling angle of the anchor bolts meets the design and construction requirements, it is necessary to measure the drilling angle of the anchor bolts. When the anchor bolt drilling rig is running, the angle of the anchor bolt drill arm 1 is consistent with that of the anchor bolt. Therefore, this technical solution is installed on one side of the drill arm 1, which allows the angle of the drill arm 1 (i.e., the anchor bolt) to be measured without affecting the operation of the drill arm 1.

[0043] Before use, the operator needs to assemble the tool. First, insert the plug 9 on one side of the connecting plate 8 into the first T-slot 7. Then, use the third fastening bolt 34 to fix the connecting plate 8 in place with the plug 9. Install the U-shaped assembly frame 13 on the lower side of the assembly plate 2 with screws. At this time, the operator pulls the strip block 26 by the translation block 27 and stretches the spring rod. After the connecting plate 8 and the assembly plate 2 are initially connected, stop pulling the translation block 27. The spring rod can pull the strip block 26 into the housing 25 and drive the plug 28 to be inserted into the strip hole 29 by the translation block 27, thus completing the connection between the connecting plate 8, the U-shaped assembly frame 13 and the assembly plate 2. Then, the level 24 can be fixed on the rotating block 16 by the connecting seat 23, the third T-slot 22 and the second fastening bolt 31. At this time, the tool is fully assembled.

[0044] The operator then places the assembly plate 2 under the drill arm 1 in a position that will not affect the normal operation of the drill arm 1. The operator uses the handwheel 33 to rotate the bidirectional screw 4, which drives the two clamping plates 3 to move closer to each other, so that the tool is clamped and fixed under the drill arm 1. The clamping plates 3 are provided with connecting blocks 5 on both the front and rear sides, and the connecting blocks 5 are provided with magnetic blocks 6 on the front side. The drill arm 1 is made of metal, and the magnetic blocks 6 can increase the tightness of the connection between the tool and the drill arm 1. The lower side of the connecting blocks 5 is slidably connected to the second T-slots 14 on both sides of the assembly plate 2. The lower side of the connecting blocks 5 is threaded with the first fastening bolts 15. The two can limit the position of the clamping plates 3 to prevent the tool from loosening between the tool and the drill arm 1 as the anchor drilling machine is running. The inner side of the clamping plates 3 is provided with elastic rubber blocks 30. Utilizing their soft and elastic properties, they can better fit the surface of the drilling platform, increase friction, and also play a role in buffering and shock absorption.

[0045] After the tool is fixed, the operator first adjusts the angle of the drill arm 1, and then rotates the rotating block 16 with the fixed shaft 11 as the center. With the help of the level 24, the rotating block 16 is turned to the horizontal. At this time, the operator can fix the position of the rotating block 16 by tightening the knob 12, and check the angle between the connecting plate 8 and the rotating block 16 by using the pointer 18 inside the observation hole 17 in conjunction with the angle plate 10. This angle is the angle between the drill arm 1 and the horizontal plane, and also the angle between the anchor rod and the horizontal plane. Before the anchor rod drilling machine is running, the operator can adjust the angle between the rotating block 16 and the connecting plate 8 to the set angle, and observe the level 24 when the drill arm 1 is running. If the level 24 is not horizontal, it means that the anchor rod angle has not reached the set angle.

[0046] The pointer 18 inside the observation hole 17 allows the operator to set the angle of the rotating block 16. The U-shaped part 19 and the magnifying glass 21 prevent sand and gravel generated during construction from entering the observation hole 17 and affecting the angle observation effect. The magnifying glass 21 and the lighting lamp 32 work together to improve the operator's observation effect and ensure the accuracy of the set angle. After the device and tools are used, the connecting bolt 20, threaded hole, positioning groove and positioning block can be separated and the observation part can be removed for cleaning.

[0047] This technical solution adopts a modular design concept, with flexible connections between various components that are easy to disassemble and assemble. Components can be quickly adjusted and replaced according to actual needs in different construction scenarios, improving the versatility and practicality of the tool.
