Description

Technical Field

[0002] In the monitoring of surrounding rock mining stress / deformation in the fields of geotechnical engineering such as mines, tunnels and hydropower stations, anchoring agents, as key materials for equipment anchoring, can anchor and bond various equipment. The amount of anchoring agents fed in and the degree of anchoring are crucial to ensure the safe installation of monitoring equipment and the accuracy of data. Too much anchoring agent fed in will cause the equipment to be exposed, posing a safety hazard; too little will affect the fixing effect of the equipment and cause distortion of monitoring data. The compaction degree of the anchoring agent directly affects the anchoring effect. Too much or too little driving force will cause unstable anchoring of the equipment. In addition, the diameter and depth of the boreholes in actual construction are generally different, making it difficult to unify the standards for the feeding and control of the anchoring agent, which increases the difficulty of construction.

The anchoring force of the anchor can be measured by the pressure sensing device, and the compaction degree of the anchor can be controlled according to the anchoring force. A sharpened protective sheet 9 of appropriate length is provided at the end of the sheet pressure sensor 8. The sharpened protective sheet 9 is made of a lightweight and high-strength composite aluminum alloy material, and the cross-sectional size of its starting end is the same as the cross-sectional size of the end of the sheet pressure sensor 8. The sharpened protective sheet 9 can protect the sheet pressure sensor 8 on the one hand, and on the other hand, it can penetrate the blockage of the channel to facilitate the cleaning of the channel. In addition, the sharpened protective sheet 9 also realizes the protection of the end expansion rod body 17 to most of the laser ranging sensor device, the visualization camera device and the pressure sensor device, forming an integrated device.

[0034] like Figure 1 A, Figure 2 and Figure 5The data image display screen 4-1 shown is connected to the laser ranging sensor device, the visualization camera device and the pressure sensor device by a quick plug-in circuit.

The sizes of the balls 15-1, the internal linear guides 15-2 and the external linear guides 15-3 are consistent with each other and are all on the same horizontal line. The ball-type linear guide 15 can greatly reduce the friction between the outer hollow rod body 1 and the inner hollow rod body 2, effectively avoiding the jamming problem between the two rods, and realizing the high efficiency and smoothness of the rod operation.

The upper and lower surfaces of the outer surface of the pair of plugs 13 are provided with limited protrusions 25, which can be inserted into the plug hole 23 horizontally and rotated to be tightly clamped with the limited stoppers 24 at the top and bottom of the plug hole 23. A through circular hole 26 is designed at the beginning of the inner hollow rod body 2. On the one hand, it is connected and penetrated with the hollow part inside the inner hollow rod body 2, and on the other hand, foreign matter inside the inner hollow rod body 2 can be discharged from this hole.

[0045] Preferably, anti-roll cylinders 27 are provided at both ends of the inner linear guide 15 - 2 , and the anti-roll cylinders 27 are used to limit the ball 15 - 1 from rolling outward and limit the axial rotation of the inner hollow rod body 2 , and the anti-roll cylinders 27 are consistent in shape and size with the ball-type linear guide 15 .

[0046] Specifically, if Figure 1 B and Fig.10 As shown, the inner linear guide 15-2 of each section of the outer hollow rod body 1 is provided with a suitable length of anti-roll cylinder 27 at both ends to limit the ball 15-1 from rolling outwards, closing the entire ball-type linear guide 15 in the rod body. The anti-roll cylinder 27 is consistent in shape and size with the inner linear guide 15-2 and the outer linear guide 15-3. When each section of the outer hollow rod body 1 is inserted into the corresponding inner hollow rod body 2, the anti-roll cylinder 27 can fit with the outer linear guide 15-3 to further completely limit the inner hollow rod body 2 from rotating in the axial direction. The coupling effect of the anti-roll cylinder 27, the plug-in joint 13 and the limit stop block 24 can connect the sections of the inner hollow rod body 2 into a stable whole.

[0047] Preferably, an elliptical cross-section cylinder 28 is connected to the reverse end surface of the start end of the anti-roll cylinder 27 at the start end of the outer hollow rod body, and the diameter of the elliptical cross-section cylinder 28 is the same as that of the anti-roll cylinder 27 .

[0048] Specifically, the starting end faces of the left and right anti-roll cylinders 27 are reversely connected with elliptical cross-section cylinders 28 of appropriate length and the same diameter as the anti-roll cylinders 27. The elliptical cross-section cylinders 28 enable the inner hollow rod body 2 to fit tightly against the outer linear guide rail 15-3 during axial operation, thereby removing residual foreign matter in the guide rail to prevent it from entering the interior of the rod body. The elliptical cross-section cylinders 28 can also prevent the handle 3 of the inner hollow rod body 2 from colliding with the starting end of the outer hollow rod body 1, thereby preventing hand squeezing accidents.

[0049] In summary, the digital portable anchor bolt anchoring agent delivery device provided in the embodiment of the present application has the following technical effects: The device is assembled by two or more sections of inner hollow rod body 2 and outer hollow rod body 1, as well as a limit locking device and a detachable power supply 10, so that the whole device can be flexibly carried and used in a limited space such as a mine tunnel, and the convenience of carrying and disassembly is realized. A completely closed ball-type linear guide 15 is set between the outer hollow rod body 1 and the inner hollow rod body 2, so that the friction between the outer hollow rod body 1 and the inner hollow rod body 2 is reduced when the two rod bodies are in operation, effectively avoiding the jamming problem between the two rods, and ensuring the efficiency and smoothness of the operation of the rod bodies. By setting a visual camera device to realize visualization in the borehole, it is possible to timely discover hidden dangers of anchoring agent transmission such as blockage of the channel before the anchoring agent is delivered, protrusion of foreign objects on the hole wall, and incomplete cleaning of rock and soil debris at the bottom of the hole. By setting a laser ranging sensor device to detect the drilling depth of the equipment in real time, the amount of anchoring agent required is determined in combination with the length of the required installation equipment, and the precise control of the amount of anchoring agent delivered is realized. By setting up a pressure sensing device, the anchoring force of the anchor at the bottom of the hole can be detected in real time, thereby achieving precise control of the compaction degree of the anchor, thereby improving the stability of the anchoring of the installation equipment. The sharpened protective sheet 9 at the end of the sheet pressure sensor 8 enables the anchor to rely on its own pointed tip to clear the hole when it encounters blockage in the hole during the delivery process. This can both protect the sheet pressure sensor 8 and prevent blockage in the hole, thereby ensuring that the anchor can be delivered smoothly.

[0050] Overall, the embodiment of the present application can visually monitor the anchoring agent delivery process of the anchor rod, timely discover and eliminate transmission hazards such as channel blockage, and ensure the efficient and smooth delivery of the anchoring agent. During the delivery process, the device can accurately control the amount of anchoring agent delivered according to different drilling hole sizes, and detect the anchoring force of the anchoring agent at the bottom of the hole in real time, thereby controlling the compaction degree of the anchoring agent, flexibly adapting to different construction environments, and significantly improving the anchoring stability and success rate of the equipment.
