Description

Technical Field

[0001] The present invention relates to the field of fixed buildings, and particularly to a concrete pipe pile splicer. Background Art

[0002] With the continuous development of the construction industry, pipe piles have become one of the most commonly used fittings in the construction industry. When using pipe piles, it is necessary to splice the pipe piles according to the required length and depth of use to meet the required use height after connecting multiple piles.

[0003] After retrieval, a Chinese patent application with the publication number of CN112726585B discloses a concrete pipe pile splicer, including a fixed shell. A plurality of second sliding openings are provided on the side wall of the fixed shell. The plurality of second sliding openings are circumferentially distributed on the side wall of the fixed shell and are in the same horizontal plane. A sliding rod is slidably connected in each of the plurality of second sliding openings. A clamping plate is provided at one end of each of the plurality of sliding rods close to each other, and a pressing member is provided at the other end. An installation groove is provided on the end wall of each of the plurality of clamping plates close to each other. In the present invention, the plurality of clamping plates are controlled to approach and separate from each other by the sliding rods, and a connecting plate is slidably connected between the ends of every two clamping plates, so as to adjust the diameter of the ring formed by the plurality of clamping plates and the connecting plate, so that the splicer can be applicable to pipe piles with different diameters for butt joint, and the problem that the upper and lower pipe piles are not easy to align during the butt joint of pipe piles is solved by the cooperation of four centering plates.

[0004] When the existing splicer performs butt joint treatment on the pipe pile, the connection part of the pipe pile is usually fixed inside the splicer, and the pipe pile is fixedly connected by a fastening bolt. However, during the connection process, since the pipe pile is made of concrete, the gravity of the pipe pile is relatively heavy. Therefore, the pipe pile will shake under the action of gravity, resulting in the inclination of the connection of the pipe pile. Summary of the Invention

[0005] In order to achieve the above object, the present invention adopts the following technical solutions: A concrete pipe pile splicer, including a sleeve. Threaded holes are provided at positions near the top and bottom on both sides of the outer wall of the sleeve, and a screw is threadedly connected to the inner wall of the threaded hole. A turntable is welded to one end of the screw. Adjacent two screws are in the same plane. A partition is connected to the inner wall of the sleeve by bolts. A plurality of guide grooves are provided at positions near the top and bottom of the circumferential inner wall of the sleeve, and a guide block is slidably connected to the inner wall of the guide groove. A backing plate is welded to one side of the guide block. The two backing plates are symmetrically distributed on both sides of the partition. A first spring is connected between the two backing plates and the partition by bolts. A fixing mechanism is provided between the backing plate and the partition.

[0006] Preferably, the fixing mechanism is composed of two fixing plates and two swinging plates. The two fixing plates are symmetrically distributed on both sides of the backing plate. One end of the swinging plate is hinged to the backing plate, and the other side of the swinging plate is hinged to the fixing plate. Convex ridges are provided on the opposite sides of the two fixing plates. A spring plate is bolted between one side of the swinging plate and the backing plate. A support seat is bolted to the top of the backing plate, and the bottom of the support seat is arc-shaped. A pushing component is provided between the bottom of the backing plate and the top of the partition plate, and a zipper is provided between the pushing component and the swinging plate.

[0007] Preferably, the pushing component is composed of two push rods and a plurality of sliders. The two push rods are distributed in an X shape. The two push rods are rotatably connected by a bearing. Chutes are provided at the bottom of the backing plate and the top of the partition plate, and the positions of the two chutes correspond to each other. Both sides of the inner walls of the two chutes are slidably connected to the sliders. The top and bottom of the two push rods are hinged to the sliders.

[0008] Preferably, through holes are provided through the two sides of the top of the backing plate and the chutes, and the zipper is slidably connected to the through holes. The two ends of the zipper are fixedly connected between one side of the swinging plate and the top of the slider respectively. The two zippers are cross-distributed, and the two zippers are slidably connected to the bottom of the support seat.

[0009] Preferably, a reinforcing mechanism is provided inside the sleeve, and the reinforcing mechanism is located above the fixing mechanism, and the reinforcing mechanism forms a cooperation with the fixing mechanism.

[0010] Preferably, the reinforcing mechanism includes a reinforcing plate, a bracket, a guide plate and a top plate. A second spring is bolted between one side of the reinforcing plate and the inner wall of the sleeve. Notches are provided on both sides of the top of the backing plate, and the notches are slidably connected to the guide plate. One side of the bracket is bolted to the sleeve. Rotating shafts are rotatably connected between both sides of the guide plate and the bracket through bearings. One side of the guide plate is inclined. One end of the top plate is bolted to a position near the top of one side of the guide plate, and the other end of the top plate contacts one side of the reinforcing plate.

[0011] Preferably, a plurality of anti-slip grooves are provided on the opposite sides of the two reinforcing plates, and tips are provided at the edges of the anti-slip grooves. The cross-section of the tips is triangular.

[0012] Preferably, a sloping plate is bolted to a position at the bottom of one side of the guide plate, and the cross-section of the sloping plate is triangular. The inclined surface of the sloping plate fits the one side of the guide plate.

[0013] The beneficial effects of the present invention are: Through the provided fixing mechanism, when connecting pipe piles, insert two pipe piles into the interior of the sleeve. At this time, one end of the pipe pile will contact the support seat. Then, under the action of gravity, the pipe pile will push the backing plate downward. When the backing plate moves downward, it will extrude the pushing component. Since the pushing component is distributed in an X shape, when the pushing component is extruded, it will expand to both sides. At this time, while expanding, the pushing component will push the slider to slide, and while the slider slides, it will pull the zipper. At this time, since the two zippers are cross-distributed, the slider sliding to the right will pull the left zipper, and the slider sliding to the left will pull the right zipper. At this time, the swing plate will deflect to one side under the action of the pulling force, and when the swing plate deflects, the extrusion force on the fixed plate will increase. At this time, through the fixed plate, the connection of the pipe pile can be effectively positioned and fixed, thus facilitating the pile connection of the two pipe piles and preventing the pipe pile from shaking under the action of gravity due to the heavy weight of the pipe pile made of concrete during the connection process, which may cause the connection of the pipe pile to tilt. Through the provided fixing mechanism and reinforcement mechanism, when the fixing mechanism is used to position and fix the connection of the pipe pile, the backing plate will slide downward under the action of the gravity of the pipe pile. At this time, when the backing plate slides, it will contact the inclined guide plate. Then, the inclined guide plate will deflect to one side under the pressure of the backing plate. When the backing plate contacts the inclined plate during downward movement, the inclined plate will drive the guide plate to tilt to one side under the pressure of the backing plate, and the other end of the guide plate will deflect in the opposite direction under the action of the bracket and the rotating shaft. At this time, when the other end of the guide plate deflects in the opposite direction, it will drive the top plate to slide to one side, and the top plate will push the reinforcement plate to move toward one side of the pipe pile, so as to reinforce both sides of the pipe pile. Since the reinforcement plate and the fixed plate are perpendicularly distributed, through the dual action between the fixed plate and the reinforcement plate, the connection of the pipe pile can be effectively fixed, so as to improve the stability of the pipe pile connection. Through the cooperation between the fixing mechanism and the reinforcement mechanism, the fixing effect of the pipe pile connection can be effectively improved. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0016] Example 1, referring to Figures 1-6 , a concrete pipe pile splicer, including a sleeve 1. Threaded holes 2 are provided on both sides of the outer wall of the sleeve 1 near the top and bottom, and a screw 3 is threadedly connected to the inner wall of the threaded hole 2. One end of the screw 3 is welded with a turntable 4. Two adjacent screws 3 are located on the same plane. The inner wall of the sleeve 1 is bolted with a partition board 5. A plurality of guide grooves are provided on the inner circumferential wall of the sleeve 1 near the top and bottom, and a guide block 12 is slidably connected to the inner wall of the guide groove. A backing plate 8 is welded to one side of the guide block 12. The two backing plates 8 are symmetrically distributed on both sides of the partition board 5. A first spring 9 is bolted between the two backing plates 8 and the partition board 5. A fixing mechanism 6 is arranged between the backing plate 8 and the partition board 5, which can effectively perform positioning and fixing treatment on the connection of the pipe piles, so as to facilitate the splicing of two pipe piles, and prevent the pipe piles from shaking under the action of gravity due to the heavy weight of the pipe piles made of concrete during the connection process, which may cause the connection of the pipe piles to be inclined.

[0017] On the above basis, the fixing mechanism 6 is composed of two fixing plates 14 and two swing plates 17. The two fixing plates 14 are symmetrically distributed on both sides of the backing plate 8. One end of the swing plate 17 is connected to the backing plate 8 through a hinge, and the other side of the swing plate 17 is connected to the fixing plate 14 through a hinge. Convex ribs 15 are provided on the opposite sides of the two fixing plates 14. A spring plate 19 is bolted between one side of the swing plate 17 and the backing plate 8. A support seat 16 is bolted to the top of the backing plate 8. The bottom of the support seat 16 is arc-shaped. A pushing component 11 is arranged between the bottom of the backing plate 8 and the top of the partition board 5. A zipper 18 is arranged between the pushing component 11 and the swing plate 17.

[0018] On the basis described above, the pushing component 11 is composed of two push rods 20 and a plurality of sliders 21, and the two push rods 20 are distributed in an X shape. A rotational connection is formed between the two push rods 20 through bearings. Chutes 10 are provided at the bottom of the backing plate 8 and the top of the partition plate 5, and the positions of the two chutes 10 correspond to each other. Both sides of the inner walls of the two chutes 10 are slidably connected to the sliders 21. The top and bottom of the two push rods 20 are hinged to the sliders 21 respectively.

[0019] On the basis described above, through holes are penetrated between the two sides of the top of the backing plate 8 and the chutes 10, and the zipper 18 is slidably connected to the through holes. The two ends of the zipper 18 are fixedly connected to one side of the swing plate 17 and the top of the slider 21 respectively. The two zippers 18 are cross - distributed and are slidably connected to the bottom of the support base 16. When the pushing component 11 is squeezed, the pushing component 11 will expand to both sides. At this time, while the pushing component 11 expands, it will push the slider 21 to slide, and while the slider 21 slides, it will pull the zipper 18. At this time, because the two zippers 18 are cross - distributed, the slider 21 sliding to the right will pull the left zipper 18, and the slider 21 sliding to the left will pull the right zipper 18. At this time, the swing plate 17 will deflect to one side under the action of the pulling force, and the squeezing force of the swing plate 17 on the fixed plate 14 will increase when it deflects. At this time, through the fixed plate 14, the connection of the pipe piles can be effectively positioned and fixed, so as to facilitate the pile - joining process of the two pipe piles.

[0020] Embodiment 2, referring to Figures 1-7 , a concrete pipe pile pile - joining device. Compared with Embodiment 1, on the basis of Embodiment 1, a reinforcement mechanism 7 is arranged inside the sleeve 1, and the reinforcement mechanism 7 is located above the fixing mechanism 6, and the reinforcement mechanism 7 forms a cooperation with the fixing mechanism 6.

[0021] On the basis described above, the reinforcement mechanism 7 includes a reinforcement plate 22, a bracket 27, a guide plate 26 and a top plate 25. A second spring 24 is bolted between one side of the reinforcement plate 22 and the inner wall of the sleeve 1. Notches 13 are formed on both sides of the top of the backing plate 8, and the notches 13 are slidably connected to the guide plate 26. One side of the bracket 27 is bolted to the sleeve 1. Rotating shafts 28 are rotatably connected between both sides of the guide plate 26 and the bracket 27 through bearings. One side of the guide plate 26 is inclined. One end of the top plate 25 is bolted to a position near the top of one side of the guide plate 26. The other end of the top plate 25 contacts one side of the reinforcement plate 22. A plurality of anti-slip grooves 23 are formed on both sides of the two reinforcement plates 22 facing each other, and tips are provided at the edges of the anti-slip grooves 23. The cross-section of the tips is triangular. A sloping plate 29 is bolted to a position at the bottom of one side of the guide plate 26, and the cross-section of the sloping plate 29 is triangular. The inclined surface of the sloping plate 29 fits the one side of the guide plate 26. When the backing plate 8 contacts the sloping plate 29 during downward movement, the sloping plate 29 will drive the guide plate 26 to tilt to one side under the pressure of the backing plate 8, and the other end of the guide plate 26 will deflect in the opposite direction under the action of the bracket 27 and the rotating shafts 28. At this time, the other end of the guide plate 26 will drive the top plate 25 to slide to one side during reverse deflection, and the top plate 25 will push the reinforcement plate 22 to move towards one side of the pipe pile, so that the reinforcement plate 22 reinforces both sides of the pipe pile. Since the reinforcement plate 22 and the fixing plate 14 are vertically distributed, the connection of the pipe pile can be effectively fixed through the dual action between the fixing plate 14 and the reinforcement plate 22, so as to improve the stability of the pipe pile connection. The cooperation between the fixing mechanism 6 and the reinforcement mechanism 7 can effectively improve the fixing effect of the pipe pile connection.

[0022] In summary, by means of the above technical solution of the present invention: when connecting pipe piles, insert two pipe piles into the inside of the sleeve 1. At this time, one end of the pipe pile will contact the support seat 16. At this time, the pipe pile will push the backing plate 8 downward under the action of gravity. When the backing plate 8 moves downward, it will squeeze the pushing component 11. Since the pushing component 11 is distributed in an X shape, when the pushing component 11 is squeezed, the pushing component 11 will expand to both sides. At this time, while the pushing component 11 expands, it will push the slider 21 to slide, and while the slider 21 slides, it will pull the zipper 18. At this time, since the two zippers 18 are cross-distributed, the slider 21 sliding to the right will pull the left zipper 18, and the slider 21 sliding to the left will pull the right zipper 18. At this time, the swing plate 17 will deflect to one side under the action of the pulling force, and when the swing plate 17 deflects, the squeezing force on the fixed plate 14 will increase. At this time, the connection of the pipe pile can be effectively positioned and fixed through the fixed plate 14, so as to facilitate the pile joining of the two pipe piles, and prevent the pipe pile from shaking under the action of gravity due to the fact that the pipe pile is made of concrete, resulting in the connection of the pipe pile being inclined. When the connection of the pipe pile is positioned and fixed by the fixing mechanism 6, the backing plate 8 will slide downward under the action of the gravity of the pipe pile. At this time, when the backing plate 8 slides, it will contact the inclined guide plate 26. At this time, the inclined guide plate 26 will deflect to one side under the pressure of the backing plate 8. When the backing plate 8 contacts the inclined plate 29 when moving downward, the inclined plate 29 will drive the guide plate 26 to incline to one side under the pressure of the backing plate 8, and the other end of the guide plate 26 will deflect in the opposite direction under the action of the bracket 27 and the rotating shaft 28. At this time, when the other end of the guide plate 26 deflects in the opposite direction, it will drive the top plate 25 to slide to one side, and the top plate 25 will push the reinforcing plate 22 to move toward one side of the pipe pile, so that the reinforcing plate 22 reinforces both sides of the pipe pile. Since the reinforcing plate 22 and the fixed plate 14 are vertically distributed, the connection of the pipe pile can be effectively fixed through the dual action between the fixed plate 14 and the reinforcing plate 22, so as to improve the stability of the pipe pile connection. The cooperation between the fixing mechanism 6 and the reinforcing mechanism 7 can effectively improve the fixing effect of the pipe pile connection.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
