Description

Technical Field

[0001] This utility model relates to the field of geotechnical engineering technology, and in particular to a pipe-slot anchor support structure. Background Technology

[0002] The slotted anchor provides active support to the soil and rock mass immediately after installation. When the soil and rock mass deforms, the anchor restricts the deformation and displacement of the soil and rock mass through friction and compression with the borehole wall, thereby maintaining the stability of the soil and rock mass. When the slotted anchor forms a certain density distribution in the soil and rock mass, it can combine multiple thin rock layers or weak rock layers into a whole "composite beam", improving the bending strength and bearing capacity of the rock layer.

[0003] The slotted anchor support includes the anchor rod body, which is made of high-strength steel and has a slotted tubular structure. The presence of slots allows the anchor rod to deform and fit tightly against the borehole wall after being driven into the hole, generating friction and extrusion forces to achieve anchoring. The tray is installed at the tail of the anchor rod to evenly transfer the support force of the anchor rod to the surface of the rock and soil, thereby increasing the support effect. The shape and size of the tray can be selected according to actual needs.

[0004] The existing slotted anchor support structure lacks a lifting function, which may lead to construction workers having to use unsafe climbing methods (such as climbing simple scaffolds) to install anchors, increasing the risk of falls from heights. Therefore, a slotted anchor support structure is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a slotted anchor support structure, which aims to improve the problem of increased personnel safety risks in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A slotted anchor bolt support structure includes a shell, a crank handle rotatably connected to the left side of the shell, a clamping assembly provided at the top of the shell for fixing the anchor bolt, a gear two fixedly connected to one end of the crank handle, a fixing block fixedly connected inside the shell, a gear one rotatably connected to one end of the fixing block, the gear one meshing with the gear two, a rack meshing with the right side of the gear one, a support plate fixedly connected to the top of the rack, and the support plate abutting against the top of the shell.

[0008] As a further description of the above technical solution:

[0009] The clamping assembly includes a support plate that abuts against the top of the housing. A sliding plate is slidably connected inside the support plate. A motor is fixedly connected to the bottom of the sliding plate. The motor is fixedly connected to the top of the rack. Multiple evenly distributed tracks are fixedly connected to the top of the support plate. Slider blocks are slidably connected to both sides of the multiple tracks. A sliding rod is fixedly connected to the bottom of the slider. The sliding rod is slidably connected inside the sliding plate. A gripper is fixedly connected to the top of the slider.

[0010] As a further description of the above technical solution:

[0011] The top of the slider is abutted against and connected to the base, and the top of the base is fixedly connected to a steel pipe;

[0012] As a further description of the above technical solution:

[0013] A ratchet is rotatably connected to the outer periphery of the crank handle;

[0014] As a further description of the above technical solution:

[0015] The top of the ratchet is abutted against and connected to a mounting block, and a mounting rod is rotatably connected inside the mounting block. The mounting rod is fixedly connected to one side of the housing, and a mounting plate is fixedly connected to one side of the mounting block.

[0016] As a further description of the above technical solution:

[0017] A limiting plate is fixedly connected to the bottom end of the rack, and the limiting plate is abutted against the bottom side of the housing;

[0018] As a further description of the above technical solution:

[0019] A fixing plate is fixedly connected inside the housing, and the rack slides inside the fixing plate.

[0020] As a further description of the above technical solution:

[0021] The bottom of the housing is fixedly connected to a number of evenly distributed casters.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, cranking the handle can drive gear two to rotate, and the rotation of gear two can drive gear one to rotate and simultaneously drive the rack to rise and fall. In underground engineering (such as mine roadways and tunnels) or slope engineering, using lifting equipment to control the raising and lowering of the slotted anchor bolt can more accurately align the anchor bolt with the pre-drilled hole. Especially in situations where space is limited, the drilling position is high, or it is difficult to operate directly, the lifting equipment can flexibly adjust the position of the anchor bolt to ensure that the anchor bolt is smoothly inserted into the drilling hole and improve the accuracy of installation.

[0024] 2. In this invention, the sliding slider drives the gripper to clamp the steel pipe, and the clamping device can firmly fix the anchor rod, preventing it from shaking or shifting when subjected to external forces (such as hammering force, thrust, etc.). For example, when using an impact hammer or anchor drilling machine to install anchor rods, without a clamping device, the anchor rod may swing unnecessarily under the impact force, causing it to fail to accurately enter the borehole or cause uneven damage to the borehole wall.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3This utility model provides an embodiment of a pipe-slot anchor support structure, including a housing 1. A crank 4 is rotatably connected to the left side of the housing 1. Cranking the crank 4 can drive a second gear 15 to rotate. One end of the crank 4 is fixedly connected to the second gear 15. During the rotation of the second gear 15, it can drive a first gear 9. A fixing block 11 is fixedly connected inside the housing 1. The fixing block 11 is installed inside the housing 1 to support the first gear 9. One end of the fixing block 11 is rotatably connected to the first gear 9. The first gear 9 is meshed with the second gear 15. A rack 8 is meshed with the right side of the first gear 9. The rack 8 can be raised and lowered by the rotation of the first gear 9. A support plate 6 is fixedly connected to the top. The support plate 6 is used to install a clamping assembly. The support plate 6 is abutted against the top of the housing 1. The housing 1 is used to install a lifting assembly.

[0034] Reference Figures 1-3 The top of the housing 1 is provided with a clamping assembly for fixing the anchor rod. The clamping assembly includes a support plate 6, which is abutted against the top of the housing 1. A sliding plate 13 is slidably connected inside the support plate 6. During the rotation of the sliding plate 13, it can drive the gripper 20 to clamp. A motor 14 is fixedly connected to the bottom inside the sliding plate 13. The drive end of the motor 14 can drive the sliding plate 13 to rotate. The motor 14 is fixedly connected to the top of the rack 8. Multiple evenly distributed tracks 2 are fixedly connected to the top of the support plate 6. The tracks 2 are used to install sliders 3 to slide inside the tracks 2. Sliders 3 are slidably connected to both sides of the multiple tracks 2. The sliders 3 can drive the gripper 20 to clamp through the sliding rod 19. A sliding rod 19 is fixedly connected to the bottom of the slider 3. During the sliding of the sliding rod 19, it can drive the slider 3 to slide inside the track 2. The sliding rod 19 is slidably connected to the inside of the sliding plate 13. A gripper 20 is fixedly connected to the top of the slider 3. During the sliding of the gripper 20, it can fix the steel pipe 7.

[0035] Reference Figures 1-3The top of the slider 3 is connected to the base 5, and the top of the base 5 is fixedly connected to the steel pipe 7. The steel pipe 7 can prevent gas outbursts and coal seam spontaneous combustion, thus improving the safety level of the mine. The crank handle 4 is rotatably connected to the ratchet 16. The ratchet 16 can fix the gear through the mounting block 17. The top of the ratchet 16 is connected to the mounting block 17, and the mounting block 17 can release the gear by pressing the mounting plate 18. The mounting block 17 is rotatably connected to the inside of the mounting rod 22, which supports the mounting block 17 and is fixedly connected to the base 5. A mounting plate 18 is fixedly connected to one side of the housing 1 and the mounting block 17. The mounting plate 18 is used to press the mounting block 17. A limiting plate 12 is fixedly connected to the bottom end of the rack 8. The limiting plate 12 is used to limit the rack 8 to prevent it from sliding out. The limiting plate 12 is abutted against the bottom side of the housing 1. A fixing plate 10 is fixedly connected inside the housing 1. The fixing plate 10 is used to limit the position of the limiting block 12. The rack 8 slides inside the fixing plate 10. A number of evenly distributed casters 21 are fixedly connected to the bottom of the housing 1. The casters 21 can drive the housing 1 to slide easily and reduce manual force.

[0036] Working principle: The motor 14 drives the sliding plate 13 to rotate. During rotation, the sliding plate 13 drives the sliding rod 19 and simultaneously the slider 3, causing the gripper 20 to clamp the steel pipe 7. This provides a stable installation environment for the anchor bolt, preventing it from moving due to external factors (such as vibrations or minor collisions at the construction site). This stability facilitates continuous installation operations, such as continuous hammering or rotary propulsion. For example, when using an electric rotary device to install anchor bolts, stable clamping allows the anchor bolt to continuously and stably enter the borehole during rotation, avoiding interruptions to the installation process due to anchor bolt swaying, thereby increasing installation speed.

[0037] Cranking handle 4 drives gear 2 15 to rotate, which in turn drives gear 1 9 to rotate. Gear 1 9's rotation causes rack 8 to rise and fall. The lifting device can flexibly position the anchor rod at a suitable height and angle, ensuring optimal matching of the anchor rod's force direction with the soil and rock structure, thereby improving the effectiveness of anchor rod support. For example, in the support of rock slopes with inclined joints, adjusting the installation angle of the anchor rod according to the joint's inclination direction can better utilize the anchoring force of the anchor rod to stabilize the slope. A limit block 12 is provided at the bottom of rack 8 to prevent rack 8 from falling off. When it is necessary to retract, pressing the mounting plate 18 can release the ratchet 16 from the mounting block 17, and simultaneously cranking handle 4 can retract the steel pipe.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
