DETAILED DESCRIPTION
[0017] In order to fully understand the purpose, features and effects of the present invention, the present invention is described in detail through the following specific implementation methods, but the present invention is not limited thereto.
[0018] A punch pile driver drill bit is composed of a drill bit body 1 and a connecting column 5. A lifting lug 3 is fixedly connected to the outer surface of the drill bit body 1; and a lifting ring 6 is fixedly connected to the top of the connecting column 5.
[0019] The top of the drill body 1 is fixedly connected to a fixing seat 2, a buffer cavity 4 is arranged in the fixing seat 2, a clearance hole 25 is arranged at the top of the fixing seat 2, the lower end of the connecting column 5 extends into the buffer cavity 4 through the clearance hole 25 at the top of the fixing seat 2, and the connecting column 5 is slidably connected to the fixing seat 2; the lower end of the connecting column 5 is threadedly connected to a limiting block 8 in the buffer cavity 4 through a threaded joint 7 arranged thereon, and the limiting block 8 and the buffer cavity 4 are a separate structure.
[0020] A movable frame 9 is arranged above the limit block 8, and the connecting column 5 passes through the movable frame 9 and forms a movable pulling mechanism of the drill body 1 with the movable frame 9. When the drill body collides with the punching hole, the pulling structure limits the connecting column 5, and the drill body 1 uses the buffer chamber 4 to perform smooth punching.
[0021] The movable frame body 9 is composed of a first movable frame 91 and a second movable frame 92. The cross-sections of the first movable frame 91 and the second movable frame 92 are semicircular ring structures, respectively. The first movable frame 91 and the second movable frame 92 cooperate with each other to form a sleeve. The inner surface of the first movable frame 91 is vertically fixedly connected with a plurality of limit columns 10. The connecting column 5 is provided with a through hole 11 adapted to the limit hole 12. The inner surface of the second movable frame 92 is provided with a limit hole 12 adapted to the limit column 10. The limit column 10 and the through hole 11 and the limit hole 12 are all plug-in matched. The first movable frame 91 is installed and docked with the second movable frame 92 by plugging the limit column 10 with the through hole 11 and the limit hole 12, so that the movable frame can be stably connected to the connecting column 5 as a whole, so that the drill body 1 can smoothly cooperate with the punching pile driver to perform punching work.
[0022] The first movable frame 91 is symmetrically provided with fixing blocks 13 on both sides of the front and rear, and the second movable frame 92 is symmetrically provided with fixing blocks 14 on both sides of the front and rear. After the first movable frame 91 and the second movable frame 92 are docked, the fixing blocks 13 and the fixing blocks 2 14 are plugged and installed together.
[0023] An insert block 15 is provided on one side of the fixed block 13 corresponding to the fixed block 2 14, and a slot 21 adapted to the insert block 15 is provided on the fixed block 2 14; two inner grooves 16 are symmetrically provided at the upper and lower positions where each fixed block 13 is connected to the insert block 15, and a moving block 17 is slidably connected in each inner groove 16, and a spring 18 is provided between the moving block 17 and the inner wall of the inner groove 16; a push rod 19 and a locking block 20 are respectively provided at the left and right ends of the outer side of the moving block 17, and a locking groove 22 inserted into the locking block 20 is provided on the inner wall of the slot 21, and a built-in groove 23 adapted to the push rod 19 is provided at the upper and lower ends of the fixed block 13, and the push rod 19 is slidably connected to the built-in groove 23.
[0024] In this embodiment, the outer side surface of the plug block 15 is a sloped structure. During operation, the plug block 15 is inserted into the slot 21, and the slope on the locking block 20 will first contact the inner wall of the slot 21. Through squeezing, the slope will play a guiding effect, causing the locking block 20 to slide and contract and push the moving block 17 to compress the spring 18. After the plug block 15 is inserted into the slot 21, the spring 18 resets and pushes the moving block 17 to drive the locking block 20 to insert into the locking groove 22, and the docking of the fixed block 13 and the fixed block 2 14 can be completed, so that the two fixed block structures are stably installed together, so that the two movable frames form an integral structure. When disassembling, only the push rod 19 needs to be pressed, and the push rod 19 moves the moving block 17, drives the locking block 20 to leave the locking groove 22, and pulls out the plug block 15 to complete the disassembly.
[0025] In this embodiment, in order to expand the operating force area of the push rod 19, a push plate 24 is fixedly connected to the free end of the push rod 19. Due to the setting of the built-in groove 23, the push plate 24 is also built-in, which can protect the operating part of the push plate 24, prevent the structure from being accidentally disassembled, and improve the safety of the entire structure.
[0026] When the device is used, its working principle is as follows: when using the punching pile driver drill bit, the connecting column 5 is inserted into the buffer cavity 4, the limiting block 8 is tightened to the lower end of the connecting column 5, and the first movable frame 91 and the second movable frame 92 are docked from both sides of the connecting column 5, so that the limiting column 10 passes through and is inserted into the limiting hole 12, and the fixing block 13 and the fixing block 2 14 are docked together, that is, the first movable frame 91 and the second movable frame 92 are stably combined and fixed together to form a stable movable frame body 9 structure. When in use, the hoisting part of the punching pile driver is connected to the connecting column 5 through the lifting ring 6, that is, the drill body 1 and the punching pile driver are docked together to perform the punching operation.
[0027] In the present invention, a stable drill bit connection structure is formed by arranging structures such as a connection column, a limit block, and a movable frame, so that the drill bit and the punching pile driver can be stably connected together to perform smooth punching work. By arranging structures such as a first movable frame, a second movable frame, a first fixed block, a second fixed block, and a mounting mechanism, the entire movable frame structure can be firmly and stably positioned and installed, and can also be quickly and conveniently disassembled. After the connection part on the drill bit is worn, it can be conveniently replaced. The structure does not require the use of operating tools, and the disassembly and assembly operation saves time and effort, which greatly improves the flexibility and convenience of the entire drill bit connection structure.
[0028] Finally, it should be noted that the above are only preferred embodiments of the present invention. Of course, those skilled in the art can make changes and modifications to the present invention. If these modifications and variations fall within the scope of the claims of the present invention and their equivalent technologies, they should be considered to be within the scope of protection of the present invention.
