[0002] Anchor bolt support is a reinforcement and support method used in surface engineering projects such as slopes and deep foundation pits, as well as underground chamber construction such as tunnels and mining sites. Anchoring agent is a viscous anchoring adhesive material formulated from unsaturated polyester resin, curing agent, accelerator, and other auxiliary materials in a certain proportion. It is packaged in polyester film rolls and has excellent properties such as rapid curing at room temperature, high bonding strength, reliable anchoring force, and good durability. During anchoring operations, a special drill rod is first installed on the drilling rig to drill a hole. After drilling, the drill rod is withdrawn and removed. Then, the anchoring agent is inserted into the hole, and the anchor bolt is installed on the drilling rig. The drilling rig is operated to drive the anchor bolt to deliver the anchoring agent to the top of the hole and rotate and stir it to solidify it. Finally, the anchor bolt is tightened to complete the anchoring. When inserting the anchoring agent into the hole, it needs to be transported using an anchoring agent delivery pipe. The other end of the anchoring agent delivery pipe is connected to a high-pressure air source for blowing.

[0025] Example 1:
[0026] This embodiment provides a resin blowing device, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes a propulsion assembly 1 and a delivery tube assembly 2 that can be extended into or retracted into the working hole through the propulsion assembly 1. The delivery tube assembly 2 includes a drug cartridge input section 3 and a drug cartridge output section 4. A self-correcting and guiding elastic connection section 5 is provided between the drug cartridge input section 3 and the drug cartridge output section 4.
[0027] The drug cartridge input section 3 is used for inputting external resin drug cartridges and guiding the movement of resin drug cartridges. The drug cartridge output section 4 is used for guiding the delivery of resin drug cartridges into the working hole. The elastic connection section 5 is elastic and can play a compensating role when the relative position of the drug cartridge output section 4 and the working hole is not close enough, so that the drug cartridge output section 4 can automatically correct itself and be guided into the working hole, thereby improving work efficiency.
[0028] To ensure reliable propulsion of component 1, the propulsion component 1 includes a first connecting seat 6, a driving member 7, and a second connecting seat 8. One of the first connecting seat 6 or the second connecting seat 8 is sleeved on the drug cartridge input section 3, while the other is connected to both the driving member 7 and the drug cartridge input section 3. The first connecting seat 6 or the second connecting seat 8 sleeved on the drug cartridge input section 3 guides the movement of the drug cartridge input section 3, while the other is driven by the driving member 7, thereby causing the drug cartridge input section 3 to extend into or retract into the working hole. Both the first connecting seat 6 and the second connecting seat 8 provide support for the drug cartridge input section 3, ensuring the straightness of the drug cartridge input section 3 and allowing the resin drug cartridge to move smoothly within the drug cartridge input section 3.
[0029] In this embodiment, the two ends of the driving component 7 are rotatably connected to the first connecting seat 6 and the second connecting seat 8 respectively; the first connecting seat 6 is simultaneously connected to the driving component 7 and the first conveying pipe 11, the second connecting seat 8 is sleeved on the second conveying pipe 12, the second conveying pipe 12 can slide relative to the second connecting seat 8, and the second connecting seat 8 is fixedly connected to the anchor trolley; the driving component 7 adopts a telescopic hydraulic cylinder.
[0030] To ensure more reliable movement of the delivery tube assembly 2, the propulsion assembly 1 further includes a guide rail 9. A slider 10 is provided on one of the first connecting seats 6 or the second connecting seat 8 that is connected to the drug cartridge input section 3. The slider 10 cooperates with the guide rail 9. The cooperation between the slider 10 and the guide rail 9 guides the movement of the first connecting seat 6 or the second connecting seat 8, ensuring the movement accuracy of the drug cartridge input section 3.
[0031] In this embodiment, the guide slide rail 9 is fixedly connected to the anchor rod trolley; the extension direction of the guide slide rail 9 is the same as the extension direction of the medicine roll input part 3; the first connecting seat 6 is provided with a slider 10.
[0032] To ensure the structural reliability of the drug cartridge input section 3, the drug cartridge input section 3 includes a first delivery pipe 11 and a second delivery pipe 12. Both ends of the second delivery pipe 12 are connected to the elastic connecting part 5 and the first delivery pipe 11, respectively. The other end of the first delivery pipe 11 is connected to the resin input end via a quick connector 13. The first delivery pipe 11 and the second delivery pipe 12 are connected separately for easy disassembly and transportation; the quick connector 13 enables rapid connection to an external resin input end.
[0033] To ensure a reliable connection between the first delivery pipe 11 and the second delivery pipe 12, the second delivery pipe 12 is connected to the first delivery pipe 11 via a connecting sleeve 14. The average diameter of the first delivery pipe 11 is larger than the average diameter of the second delivery pipe 12. The connecting sleeve 14 facilitates the connection between the first delivery pipe 11 and the second delivery pipe 12. The larger diameter of the first delivery pipe 11 facilitates the entry of the resin cartridge, while the smaller diameter of the second delivery pipe 12 facilitates the precise delivery of the resin cartridge.
[0034] In this embodiment, the connecting sleeve 14 adopts two oppositely arranged semi-clamping structures 17. The two ends of the semi-clamping structure 17 are respectively engaged with the first conveying pipe 11 and the second conveying pipe 12. That is, the semi-clamping structure 17 is provided with the mounting groove of the first conveying pipe 11 and the mounting groove of the second conveying pipe 12.
[0035] To ensure the reliability of the structure of the medicine roll output section 4, the medicine roll output section 4 is a third conveying tube. One end of the third conveying tube is connected to the elastic connecting part 5, and the other end of the third conveying tube is a bevel to facilitate insertion into the hole.
[0036] To ensure reliable delivery of the resin cartridge, the third delivery pipe has at least one through hole 16 on its wall. During operation, the third delivery pipe is inserted into the hole. The small gap between the resin cartridge and the third delivery pipe makes it difficult for gas inside the pipe to escape, potentially obstructing the resin cartridge and hindering its delivery. The through hole 16 allows gas inside the pipe to escape when the resin cartridge is inserted, reducing the difficulty of delivery.
[0037] In this embodiment, eight through holes 16 are provided and divided into four groups. The four groups of through holes 16 are evenly distributed along the circumference of the third conveying pipe, and adjacent groups of through holes 16 are staggered along the axial direction of the third conveying pipe.
[0038] To ensure the structural reliability of the elastic connection part 5, such as Figure 4 , Figure 5 As shown, the elastic connection part 5 includes a bellows 18 and two first connectors 19. The two first connectors 19 are respectively connected to both ends of the bellows 18. The pill input part 3 and the pill output part 4 are provided with second connectors 20 that cooperate with the first connectors 19. The pill input part 3 and the pill output part 4 are connected through the bellows 18. The bellows 18 is elastic. When the pill output part 4 enters the working hole and is subjected to pressure, the bellows 18 can bend. After the operation is completed, the pill output part 4 leaves the working hole, and the bellows 18 can return to its original position when it is no longer subjected to pressure. The first connectors 19 and the second connectors 20 cooperate to facilitate disassembly and assembly. In particular, if the bellows 18 is bent too much, the resin pill may get stuck. The elastic connection part 5 facilitates disassembly and assembly, which can improve maintenance efficiency.
[0039] In this embodiment, the first connector 19 is annular and has external threads, and is sleeved on the bellows 18. The second connector 20 is annular and has internal threads, and is sleeved on the bellows 18. The bellows 18 and the first connector 19 are connected by welding.
[0040] To ensure a reliable connection between the corrugated pipe 18 and the first connector 19, the first connector 19 is provided with a groove 21, on which part of the corrugated pipe 18 is located; part of the pill inlet 3 is located inside the corrugated pipe 18; the outlet diameter of the first connector 19 near the pill outlet 4 is the same as the inlet diameter of the pill outlet 4, enabling the resin pill to smoothly enter the pill outlet 4 from the first connector 19. The design of the groove 21 facilitates the positioning and installation of the corrugated pipe 18; the fact that part of the pill inlet 3 is located inside the corrugated pipe 18 means that part of the second delivery pipe 12 passes through the corrugated pipe 18, allowing the resin pill to directly enter the corrugated pipe 18 after passing through the second delivery pipe 12, reducing the connection requirements between the second delivery pipe 12 and the corrugated pipe 18.
[0041] In this embodiment, a guide slope is provided at the inlet of the first connector 19 near the drug roll output section 4 to facilitate guiding the resin drug roll in the corrugated pipe 18 into the third delivery pipe.
