Description

Technical Field

[0001] This utility model relates to the field of drilling and casting technology, and in particular to a large-diameter drilling and casting equipment. Background Technology

[0002] Large-diameter drilling and pouring equipment is a core construction tool used in large-scale foundation engineering projects to form large-diameter pile foundations or diaphragm walls by drilling and pouring concrete. It is technically complex and difficult to construct, requiring comprehensive selection based on geological conditions, project requirements, and equipment performance.

[0003] As disclosed in CN220057972U, this utility model discloses a large-diameter drilling and pouring equipment, relating to the field of construction engineering technology. It includes a pouring device with a filter screen fixedly connected inside. Mounting plates are fixedly connected to both sides of the top of the pouring device. A rotating motor is fixedly connected to one side of each mounting plate. A rotating shaft is fixedly connected to the output end of the rotating motor, and a scraper is fixedly connected to one end of the rotating shaft. The scraper is positioned directly above the filter screen. By positioning the scraper directly above the filter screen, when a large amount of foreign matter and clumps clog the mesh of the filter screen, a sliding baffle is first used to allow the foreign matter and clumps to pass through the foreign matter outlet. Then, the rotating motor is started, driving the rotating shaft to rotate, causing the scraper to rotate around the shaft as the center, discharging the foreign matter and clumps from one side of the foreign matter outlet to the outside of the pouring device. This avoids excessive foreign matter and clumps clogging the mesh of the filter screen and affecting the pouring rate of the large-diameter drilling and pouring equipment.

[0004] In existing technology, two base plates are used to limit and fix the bottom of the pouring device, thereby making the pouring process more stable. A drive component and a scraper are set at the top of the pouring device. During pouring, the scraper can scrape away lumps or foreign objects to avoid blockage. However, when pouring large-diameter holes of different specifications, different pouring devices are used. If the hole is large, a pouring device of the same specification as its diameter is required. Since the size of the base plate fixing groove is fixed, it cannot be adjusted for pouring devices of different specifications, so the adaptability is poor. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the prior art that different pouring devices are used when pouring large-diameter holes of different specifications. If the hole is large, a pouring device of the same specification as the diameter is required. Since the size of the base plate fixing groove is fixed, it is impossible to adjust it for pouring devices of different specifications, resulting in poor adaptability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a large-diameter drilling and casting device, comprising a casting device body, a filter plate fixedly disposed inside the top of the casting device body, an auxiliary component disposed at the top of the casting device body, the auxiliary component comprising a ring plate fixedly connected to the casting device body, a limiting ring fixedly connected to one side of the inside of the top of the ring plate, an electric slider slidably connected to the middle of the top of the ring plate, the electric slider slidably connected to the limiting ring, and a positioning component disposed at the bottom of the casting device body, the positioning component comprising a connecting ring disposed on the outside of the bottom of the casting device body.

[0007] In a preferred embodiment, the outer wall of the connecting ring is fixedly connected to a base in an annular array. A groove is provided in the middle of the top of the base. A clamping slider is slidably connected inside the groove. A connecting block is fixedly connected to the top of the clamping slider. A fixing rod is fixedly connected to the top of the connecting block near the main body of the pouring device. A clamping plate is fixedly connected to the end of the fixing rod near the main body of the pouring device. The clamping plate abuts against the bottom of the main body of the pouring device.

[0008] In a preferred embodiment, a lead screw is rotatably connected to the center of the chute. The lead screw is threaded through the clamping slider. One end of the lead screw rotatably passes through the end of the base away from the main body of the casting device. A third gear is fixedly connected to the end of the lead screw away from the main body of the casting device. A fourth gear meshes with the top of the third gear. A second rotating rod is fixedly connected to the top of the fourth gear. The second rotating rod rotatably passes through the base.

[0009] In a preferred embodiment, the second rotating rod is rotatably connected to a connecting handle at one end outside the base. A retaining seat is provided on the outer side of the bottom end of the connecting handle. The retaining seat is fixed to the top of the base. The retaining seat has a ring array of slots in the middle, which engage with the connecting handle.

[0010] In a preferred embodiment, a scraper is fixedly connected to the top of the electric slider near the filter plate. The scraper is slidably connected to the inner wall of the pouring device body and the ring plate. A connecting plate is fixedly connected to one side of the bottom end of the scraper. A rotating roller is rotatably connected to the bottom end of the connecting plate. One end of the rotating roller rotatably passes through the scraper. The rotating roller is rotatably connected to the pouring device body. A second gear is fixedly connected to one end of the rotating roller located inside the scraper.

[0011] In a preferred embodiment, a motor is fixedly mounted on the top of the scraper, and a first rotating rod is driven to the bottom of the motor. The first rotating rod rotates through the scraper, and a first gear is fixedly connected to one end of the first rotating rod inside the scraper. The first gear is rotatably connected to a second gear.

[0012] The beneficial effects of this utility model are as follows:

[0013] In this invention, the worker places the connecting ring outside the drill hole and fixes it to the base with a pin. Then, the pouring device body is placed in the middle of the connecting ring. The connecting handle is rotated to drive the second rotating rod to rotate, the second rotating rod drives the fourth gear to rotate, the fourth gear drives the third gear to rotate, the third gear drives the lead screw to rotate, the lead screw drives the clamping slider to move, the clamping slider drives the connecting block to move, and the connecting block drives the clamping plate to approach the pouring device body through the fixing rod, thereby clamping and fixing the pouring device body. Therefore, it can be adapted to pouring device bodies of different sizes. After the pouring device body is fixed, the connecting handle is deflected to one side, and the connecting handle is deflected to a horizontal state and locked inside the slot, thereby limiting and fixing the connecting handle and preventing the clamping plate from loosening due to the rotation of the connecting handle.

[0014] The electric slider drives the scraper to rotate along the top of the ring plate. The starter motor drives the first rotating rod to rotate, which in turn drives the first gear to rotate. The first gear drives the second gear to rotate, and the rotating roller stirs the concrete on the filter plate, loosening any clumps. The roller also strikes the filter plate to increase the pouring speed. As the scraper moves, it cleans the inner wall of the ring plate and the main body of the pourer, thus improving cleanliness.

A second rotating rod 311 is fixedly connected to the top of the fourth gear 310. The second rotating rod 311 rotates through the base 32. A connecting handle 312 is rotatably connected to the end of the second rotating rod 311 located outside the base 32. A card seat 313 is provided on the outer side of the bottom end of the connecting handle 312. The card seat 313 is fixed to the top of the base 32. A card slot 314 is formed in a circular array in the middle of the card seat 313. The card slot 314 engages with the connecting handle 312.

[0025] In this embodiment, during use, the operator places the connecting ring 31 outside the drill hole and fixes the base 32 with a pin. Then, the pouring device body 1 is placed in the middle of the connecting ring 31. The connecting handle 312 is rotated to drive the second rotating rod 311 to rotate. The second rotating rod 311 drives the fourth gear 310 to rotate. The fourth gear 310 drives the third gear 39 to rotate. The third gear 39 drives the lead screw 38 to rotate. The lead screw 38 drives the clamping slider 34 to move. The clamping slider 34 drives the connecting block 35 to move. The connecting block 35 drives the clamping plate 37 to approach the pouring device body 1 through the fixing rod 36, thereby clamping and fixing the pouring device body 1. Therefore, it can be adapted to pouring device bodies 1 of different sizes. After the pouring device body 1 is fixed, the connecting handle 312 is deflected to one side. The connecting handle 312 is deflected to a horizontal state and is stuck inside the slot 314, thereby limiting and fixing the connecting handle 312 and preventing the clamping plate 37 from loosening due to the rotation of the connecting handle 312.

[0026] like Figure 1 - Figure 3As shown, a scraper 23 is fixedly connected to the top of the electric slider 22 near the filter plate 11. The scraper 23 is slidably connected to the inner wall of the pouring device body 1 and the ring plate 21. A connecting plate 24 is fixedly connected to one side of the bottom of the scraper 23. A rotating roller 29 is rotatably connected to the bottom of the connecting plate 24. One end of the rotating roller 29 rotates through the scraper 23. The rotating roller 29 is rotatably connected to the pouring device body 1. A second gear 28 is fixedly connected to one end of the rotating roller 29 inside the scraper 23. A motor 25 is fixedly installed at the top of the scraper 23. A first rotating rod 26 is driven to the bottom of the motor 25. The first rotating rod 26 rotates through the scraper 23. A first gear 27 is fixedly connected to one end of the first rotating rod 26 inside the scraper 23. The first gear 27 is rotatably connected to the second gear 28.

[0027] In this embodiment, concrete is added to the filter plate 11, the electric slider 22 is started to drive the scraper 23 to rotate along the top of the ring plate 21, the motor 25 is started to drive the first rotating rod 26 to rotate, the first rotating rod 26 drives the first gear 27 to rotate, the first gear 27 drives the second gear 28 to rotate, the rotating roller 29 rotates, the rotating roller 29 stirs the concrete on the filter plate 11, making the clumps of concrete loosen, and the rotating roller 29 strikes the filter plate 11 to improve the pouring.

[0028] Working principle: First, during use, the operator places the connecting ring 31 outside the drilled hole and fixes it to the base 32 with a pin. Then, the pouring device body 1 is placed in the middle of the connecting ring 31. Rotating the connecting handle 312 drives the second rotating rod 311 to rotate, which in turn drives the fourth gear 310 to rotate. The fourth gear 310 drives the third gear 39 to rotate, which in turn drives the lead screw 38 to rotate. The lead screw 38 moves the clamping slider 34, which in turn moves the connecting block 35. The connecting block 35, through the fixing rod 36, moves the clamping plate 37 closer to the pouring device body 1, thereby clamping and fixing the pouring device body 1. Therefore, it can be adapted to pouring device bodies 1 of different sizes. After fixing, the connecting handle 312 is deflected to one side, and the connecting handle 312 is deflected to a horizontal state and locked inside the slot 314, thereby limiting and fixing the connecting handle 312 to prevent the clamping plate 37 from loosening due to the rotation of the connecting handle 312. Then, concrete is added to the filter plate 11, and the electric slider 22 is started to drive the scraper 23 to rotate along the top of the ring plate 21. The motor 25 is started to drive the first rotating rod 26 to rotate. The first rotating rod 26 drives the first gear 27 to rotate. The first gear 27 drives the second gear 28 to rotate. The rotating roller 29 stirs the concrete on the filter plate 11, making the clumps of concrete loosen. The rotating roller 29 also strikes the filter plate 11 to improve the pouring.
