[0002] In construction fields such as tunnel excavation, mining, and urban underground engineering, non-drilling and blasting methods have gradually replaced traditional drilling and blasting methods as the mainstream construction technology due to their significant advantages such as low vibration, low noise, high safety, and minimal damage to the surrounding environment. The core working principle of non-drilling and blasting equipment (such as rock splitters, static crushing equipment, and hydraulic splitters) is to statically crush and excavate rocks or soil through hydraulic drive and mechanical force transmission. Its operating efficiency and construction quality directly depend on the reliability of the connection between the various components of the equipment, the flexibility of adaptation, and the ease of disassembly and assembly.

[0003] Meanwhile, a non-explosive tunneling drilling rig for adits, with announcement number CN213063574U, is disclosed, including a drill frame and a feeding mechanism; the feeding support extends laterally, and an impact device is installed on the feeding support for impact rock breaking; a connecting frame and the drill frame are spaced apart in the extending direction of the feeding support, and the connecting frame is fixedly connected to the feeding support; both ends of the luffing support frame are rotatably connected to the drill frame and the connecting frame; the luffing cylinder and the luffing support frame are arranged parallel to each other in the direction perpendicular to the feeding support, and both ends of the luffing cylinder are rotatably connected to the drill frame and the connecting frame; one end of the translation cylinder is rotatably connected to the drill frame, and the other end is rotatably connected to the feeding mechanism, and the translation cylinder is located in the plane formed by the luffing cylinder and the luffing support frame.

[0004] The aforementioned non-blasting adit drilling rig, equipped with a drill frame, feed mechanism, and tracked chassis, is mobile, but its overall size and weight are considerable.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0029] The following describes an embodiment of this utility model based on its overall structure.

[0030] like Figures 1 to 4As shown, this utility model provides a quick-fit connection structure for non-drilling and blasting equipment. It includes a fixing ring 6 fixed to the left outer side of the equipment connector 1, a spring pin 8 fixed to the outside of the fixing ring 6, a drill bit 2 at the left end of the equipment connector 1, and a sleeve 11 fixed to the right outer side of the drill bit 2. The right side of the sleeve 11 is fitted against the outside of the fixing ring 6. A snap-fit ​​groove 12 is provided inside the right end of the sleeve 11, and the spring pin 8 is fixed inside the snap-fit ​​groove 12. Through the fit between the fixing ring 6 and the sleeve 11, and the snap-fit ​​between the spring pin 8 and the snap-fit ​​groove 12, the connector and the drill bit 2 can be quickly assembled and securely connected, ensuring the stability and ease of assembly and disassembly of the connection, and ensuring the reliability of power transmission during drilling operations.

[0031] The outer side of the fixing ring 6 has a groove 7, and the spring pin 8 is fixed inside the groove 7. The spring pin 8 has a pin head 14 fitted inside it. The spring pin 8 provides a stable installation space and forms a limiting guide for the pin head 14, ensuring that the spring pin 8 and the pin head 14 cooperate accurately and reliably.

[0032] The sleeve 11 has an inner groove 15 on the rear side, and the drill bit 2 is fixed inside the inner groove 15. By achieving a firm positioning of the drill bit 2 inside the sleeve 11, the stability and concentricity of the drill bit 2 during the drilling process are ensured.

[0033] Semicircular elastic plates 5 are fixedly provided on both the upper and lower sides of the outer rear end of the sleeve 11. A ring 4 is attached to the outer side of the semicircular elastic plate 5. The elastic deformation characteristics of the semicircular elastic plate 5, in conjunction with the ring 4, provide pre-tightening force and buffering effect for the connection between the sleeve 11 and the fixed ring 6.

[0034] The left end of the ring 4 is fixed with a fixing body 3 on both the upper and lower sides. The front and rear sides of the sleeve 11 are rotatably provided with a bolt 10. Through the cooperation of the bolt 10 and the fixing body 3, the position of the ring 4 on the outside of the sleeve 11 can be locked, thereby fixing the state of the semi-circular elastic plate 5.

[0035] The sleeve 11 has threaded grooves 13 on both the front and rear sides, and the bolt 10 rotates inside the threaded grooves 13. The threaded grooves 13 provide a stable foundation for the bolt 10 to be installed and rotated, ensuring that the bolt 10 is subjected to uniform force and the connection is stable during the tightening process.

[0036] The fixing ring 6 has threaded holes 9 in the middle of both the front and rear sides, and the bolt 10 rotates inside the threaded holes 9. The fixing ring 6 and the sleeve 11 are detachably and firmly connected by the threaded engagement of the bolt 10 and the threaded holes 9, which facilitates assembly, disassembly and maintenance.

[0037] Working principle and process of rapid adaptation connection structure for non-drilling and blasting equipment:

[0038] The rapid adaptation connection structure of this non-drilling and blasting equipment mainly achieves rapid connection and disassembly of the equipment connector 1 and the drill bit 2 through the coordinated work of various components, so as to improve work efficiency and equipment service life.

[0039] The spring pin 8 on the outside of the retaining ring 6 engages with the snap groove 12 inside the sleeve 11, which is the key part for achieving quick connection. The spring pin 8 is fixed in the groove 7 on the outside of the retaining ring 6. When the drill bit 2 approaches the equipment connector 1, the sleeve 11 is fitted onto the outside of the retaining ring 6, and the spring pin 8 automatically snaps into the snap groove 12, thereby achieving quick connection between the equipment connector 1 and the drill bit 2. This connection method utilizes the elasticity of the spring pin 8, which can withstand large alternating loads and has good fatigue resistance, ensuring the stability of the connection. At the same time, the pin head 14 is fitted inside the spring pin 8, further enhancing the reliability of the connection. Then, the semi-circular elastic plates 5 on the upper and lower sides of the outer rear end of the sleeve 11, the outer ring 4, and the fixing bodies 3 on the upper and lower sides of the left end of the ring 4 cooperate with each other to achieve quick connection and disconnection between components. During the connection process, the semi-circular elastic plates 5 provide elastic support, allowing the ring 4 to fit tightly against the outside of the sleeve 11, while the fixing bodies 3 facilitate the movement of the ring 4. When disassembly is required, it can be easily moved by appropriate means. The external force pushes the ring 4 to separate from the semi-circular elastic plate 5, thereby quickly disconnecting the connection and greatly simplifying the assembly and disassembly process. The sleeve 11 has a bolt 10 rotatably installed in the middle of the front and rear sides. The bolt 10 rotates inside the threaded groove 13 of the sleeve 11 and the threaded hole 9 of the fixing ring 6. After the spring pin 8 is engaged in the buckle groove 12 to achieve the initial connection, the bolt 10 is rotated to screw it into the threaded groove 13 and the threaded hole 9, further tightening the connection between the equipment connector 1 and the sleeve 11 and improving the stability of the connection. This non-drilling and blasting method equipment quick-adaptive connection structure realizes the quick connection and disassembly of the equipment, improves work efficiency, and extends the service life of the equipment.
