[0028] The present utility model will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present utility model are given for the purposes of illustration and description, and are not exhaustive or limit the present utility model to the disclosed form. Many modifications and variations are obvious to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present utility model, and enable those of ordinary skill in the art to understand the present utility model and thus design various embodiments with various modifications suitable for specific purposes.

[0029] See Figure 1 , which is a structural schematic diagram of an insert type resin blowing device provided by the present utility model. In combination with Figures 1 to 8 , the insert type resin blowing device includes, for example: a driving part 10, a propulsion device 20, and a delivery pipe 30. The driving part 10 can drive the delivery pipe 30 to extend into or retract and reset into the drill hole through the propulsion device 20. Among them, the delivery pipe 30 is detachably arranged at the end of the propulsion device 20.

[0030] It can be understood that by detachably arranging the conveying pipe 30 at the end of the propulsion device 20, when the front-end conveying pipe 30 is damaged, the conveying pipe 30 can be quickly disassembled from the plug-in resin blowing device for repair and replacement, improving the disassembly and assembly efficiency of the conveying pipe, and further avoiding the long time-consuming for repair and replacement, which affects the operation.

[0031] For example, when the bolt jumbo is operating, the driving part 10 drives the propulsion device 20 to expand and contract, and then the propulsion device 20 drives the conveying pipe 30 to expand and contract, extending the conveying pipe 30 into the drill hole or retracting it to the reset position, realizing the displacement work of the conveying pipe 30.

[0032] Furthermore, the propulsion device 20 includes a telescopic pipe 22. The first end of the telescopic pipe 22 is connected to the resin input end through a quick connector, and the second end of the telescopic pipe 22 is connected to the conveying pipe 30 through a quick disassembly structure 40.

[0033] It can be understood that through the quick disassembly structure 40, the quick installation and disassembly between the telescopic pipe 22 and the conveying pipe 30 can be realized, improving the repair and replacement efficiency.

[0034] In a specific embodiment, the first end of the telescopic pipe 22 is connected to the resin input end through a quick connector, and the second end of the telescopic pipe 22 is connected to the conveying pipe 30 through a quick disassembly structure 40; the resin is blown from the resin input end into the telescopic pipe 22 through compressed air, and then enters the conveying pipe 30 from the telescopic pipe 22, realizing the deep conveying of the resin.

[0035] Furthermore, the second end of the telescopic pipe 22 is sleeved on the conveying pipe 30. The quick disassembly structure 40 includes: two relatively arranged half-clamp structures 41, and the half-clamp structure 41 is provided with a telescopic pipe 22 installation groove and a conveying pipe 30 installation groove; the two half-clamp structures 41 are detachably connected through a threaded connector 42.

[0036] For example, the half-clamp structure 41 is provided with a telescopic pipe 22 installation groove and a conveying pipe 30 installation groove along its length direction. During installation, first sleeve the telescopic pipe 22 on the outside of the conveying pipe 30, then place the telescopic pipe 22 in the telescopic pipe 22 installation groove, place the conveying pipe 30 in the conveying pipe 30 installation groove, and then connect the two semi-cylindrical half-clamp structures 41 through four threaded connectors 42, clamping the connection between the telescopic pipe 22 and the conveying pipe 30 between the two half-clamp structures 41. If the conveying pipe 30 is damaged, only need to disassemble the four threaded connectors 42 to release the fixation of the half-clamp structure 41 on the connection between the telescopic pipe 22 and the conveying pipe 30, and replace the conveying pipe 30.

[0037] Further, the propulsion device 20 further includes: a driving connecting member 21, connected between the telescopic pipe 22 and the driving portion 10, and the driving portion 10 can drive the telescopic pipe 22 to perform reciprocating telescopic movement through the driving connecting member 21.

[0038] For example, the driving connecting member 21 is an oil cylinder seat. A driving connection lug is provided above the driving connecting member 21, and a telescopic pipe 22 fixing groove is provided below the driving connecting member 21; the output end of the telescopic oil cylinder is fixedly connected to the driving connection lug, and the telescopic pipe 22 is fixedly installed in the telescopic pipe 22 fixing groove.

[0039] Further, the plug-in resin blowing device further includes: a propulsion support portion 23, provided below the propulsion device 20 and connected to the driving connecting member 21.

[0040] For example, the propulsion support portion 23 is fixedly connected below the driving connecting member 21 and is provided with a corresponding telescopic pipe 22 support groove. When the driving portion 10 drives the telescopic pipe 22 to perform reciprocating telescopic movement, the propulsion support portion 23 can be driven to perform reciprocating movement on the bolter together.

[0041] Further, the plug-in resin blowing device further includes: a guide rail support seat 60, provided with a guide slide rail 52; the propulsion support portion 23 is provided with a slider 51, and the slider 51 cooperates with the guide slide rail 52 to guide the telescopic pipe 22.

[0042] For example, the bottom of the guide rail support portion is provided with a slider 51, and a corresponding guide slide rail 52 is provided above the guide rail support seat 60. The slider 51 can reciprocally slide along the length direction of the guide rail to limit the movement direction of the telescopic pipe 22 and the delivery pipe 30.

[0043] Further, a limiting device 61 is provided on the guide rail support seat 60, and the guide rail support seat 60 is fixedly installed on the bolter through the limiting device 61.

[0044] Further, the plug-in resin blowing device further includes: a delivery support seat 70, fixedly provided on the bolter for supporting the delivery pipe 30.

[0045] Further, the driving portion 10 is a telescopic oil cylinder, and the telescopic oil cylinder is disposed opposite to the propulsion device 20. When the telescopic oil cylinder extends, the delivery pipe 30 retracts and resets; when the telescopic oil cylinder retracts, the delivery pipe 30 extends into the drill hole.

[0046] It can be understood that by arranging the telescopic oil cylinder opposite to the propulsion device 20, the structural design of the plug-in resin blowing device can be made more compact, enabling deeper resin transportation in a limited space and avoiding the problem of the excessive length of the plug-in resin blowing device caused by arranging the telescopic oil cylinder and the propulsion device 20 in a collinear manner.

[0047] For example, the plug-in resin blowing device further includes a signal feedback unit, which is electrically connected to the driving unit 10, and through which more accurate and convenient automatic display and control can be achieved.

[0048] Furthermore, the present utility model provides an anchor trolley, which includes any one of the plug-in resin blowing devices described above and can achieve the same effect. To avoid repetition, it will not be elaborated here.

All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
