Description

Technical Field

[0001] This utility model relates to the field of pipe pile connection technology, specifically to a pipe pile mechanical joint with a positioning and guiding device. Background Technology

[0002] Prestressed concrete pipe piles refer to prestressed concrete piles with a circular cross-section formed using centrifugal and prestressing processes.

[0003] The components are prefabricated in the prefabrication plant, cured, and transported to the construction site after reaching the design strength. They are then driven into the soil using a pile driver, and finally, a foundation beam (slab) is poured on top of the piles.

[0004] Existing pipe pile connection technology has the following shortcomings:

[0005] 1. The connection accuracy and tightness of the male and female connectors cannot be guaranteed. After the two are connected, they are prone to misalignment, which may cause the first and second pipe piles connected by the connector to become skewed under stress during subsequent construction, resulting in safety hazards.

[0006] 2. Generally, workers need to temporarily weld the adjacent ends of the first and second pipe piles together on the construction site. This is time-consuming and labor-intensive, and requires high welding precision. It is impossible to achieve a quick and accurate connection between the first and second pipe piles, which reduces the connection efficiency of the pipe piles and thus reduces the construction efficiency. Utility Model Content

[0007] The purpose of this utility model is to provide a mechanical joint for pipe piles with a positioning and guiding device.

[0008] To achieve this objective, the present invention adopts the following technical solution:

[0009] A mechanical joint for pipe piles with a positioning and guiding device is provided, comprising a first plug and a second plug inserted into a first pipe pile and a second pipe pile.

[0011] The male and female connectors are respectively fixed to the outer wall of one end of the first and second plugs via two connecting plates;

[0012] Flanges are fixedly installed on the outer walls of both the male and female heads in the circumferential direction. A limiting mechanism is located between the two flanges. The limiting mechanism includes several adjusting bolts and several display components. The adjusting bolts are evenly spaced on the flange of the female head, and one end of each adjusting bolt is threaded to the flange of the female head. The other end of each adjusting bolt is pressed against the flange of the male head. Each display component is located next to one of the adjusting bolts.

[0013] The male head has a conical positioning boss fixed on its outer wall. The female head has a conical positioning groove at the end near the male head for the conical positioning boss to insert into. The anti-disengagement mechanism is located between the conical positioning boss and the conical positioning groove. The anti-disengagement mechanism includes two wedge-shaped buckles and two sliding components. A positioning rod is fixed inside the conical positioning groove. The end of the conical positioning boss away from the male head has a positioning groove for the positioning rod to insert into. The two sliding components are symmetrically arranged on the inner wall of the conical positioning boss. Each wedge-shaped buckle is fixed on one sliding component.

[0014] Preferably, a gap is provided between the tapered positioning boss and the tapered positioning groove.

[0015] Preferably, the outer wall of the flange of the female head is provided with several circular guide rails at equal intervals, and each circular guide rail is fixedly connected to the flange of the female head. Each circular guide rail is provided with an arc-shaped slider, and each arc-shaped slider is provided with a mounting plate inserted on its outer wall.

[0016] Preferably, each display component includes an indicator rod and a scale plate. Each adjusting bolt has a protrusion fixed at the end away from the male head. The indicator rod is fixed on the outer wall of the protrusion, and the scale plate is fixed on the mounting plate with the indicator rod facing the scale plate.

[0017] Preferably, each protrusion has a handle fixed to its outer wall by a connecting rod.

[0018] Preferably, each sliding component includes a clamping spring, a flange, and a slide rod. The inner wall of the conical positioning boss has two symmetrically arranged slide grooves, and each wedge-shaped buckle is slidably connected to one slide groove. The inner wall of the conical positioning boss has two symmetrically arranged slide holes. The flange is slidably disposed inside one of the slide holes. The slide rod is fixedly disposed at one end of the wedge-shaped buckle, and the flange is fixedly connected to the slide rod. Each slide hole communicates with one slide groove. The clamping spring is sleeved on the end of the slide rod away from the wedge-shaped buckle. The outer wall of the flange and the inner wall of the slide hole respectively abut against the two ends of the clamping spring.

[0019] Preferably, the end of the positioning rod away from the female head is provided with a first oblique angle.

[0020] Preferably, the outer wall of the positioning rod in the circumferential direction is provided with a number of wedge-shaped slots at equal intervals, and two wedge-shaped buckles engage with two of the wedge-shaped slots.

[0021] Preferably, both the first plug and the second plug have a second bevel on their outer walls.

[0022] Preferably, a positioning bolt is fixed on the outer wall of the male head, and the positioning bolt is threadedly connected to the tapered positioning boss.

[0023] The beneficial effects of this utility model are:

[0024] 1. This utility model, through the design of a limiting mechanism, namely several adjusting bolts and several display components, can adjust the tightness of the female head against the male head in real time through several adjusting bolts, thereby controlling the insertion depth of the connector and preventing excessive squeezing that could damage the connector.

[0025] 2. This utility model, by designing several display components, compares the indication value of the indicator rod on the scale plate after each adjustment bolt extends into position with the initial position indication value of the adjustment bolt. This allows for the rapid measurement of the extension stroke of the adjustment bolt, thus revealing the clamping distance towards the male connector plate. The display components ensure that the adjustment bolts maintain a consistent extension stroke, ensuring uniform clamping force on the male flange plate. This, in turn, ensures the connection accuracy between the male and female connectors, avoids stress concentration caused by excessive insertion, and improves the overall load-bearing capacity of the connector.

[0026] 3. This utility model, through the design of an anti-detachment mechanism, namely two wedge-shaped buckles and two sliding components, can lock the male and female ends after each docking, preventing the first and second pipe piles from detaching during construction, thereby improving the firmness of the joint.

[0027] 4. This utility model, through the design of a male head, a female head, a limiting mechanism, and an anti-detachment mechanism, enables the male and female heads to quickly connect, thereby achieving rapid connection between the first and second pipe piles. This eliminates the need for workers to temporarily weld the ends of the first and second pipe piles on the construction site, saving time and effort, improving the connection efficiency of the first and second pipe piles, and thus improving construction efficiency.

[0028] 5. The present invention uses a positioning bolt to enable the disassembly and assembly of the tapered positioning boss and the male head. That is, when the tapered positioning boss on the male head is deformed by collision during construction or transportation, it can be quickly removed and replaced without discarding the entire joint, thus reducing the cost of use and without delaying construction efficiency.

[0029] 6. This utility model designs a 1-2mm gap between the conical positioning boss and the conical positioning groove, which allows the conical positioning boss to adjust the insertion angle in real time during the insertion process, so that the conical positioning boss can be quickly and automatically aligned after being in place, thereby improving the docking accuracy of this connector.

[0038] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0039] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0040] Reference Figures 1 to 6 As shown, a mechanical joint for pipe piles with a positioning and guiding device includes a first plug 3 and a second plug 4 inserted into a first pipe pile 1 and a second pipe pile 2.

[0041] It also includes male head 5, female head 6, a limiting mechanism, and an anti-detachment mechanism;

[0042] The male connector 5 and the female connector 6 are respectively fixed to the outer wall of one end of the first plug 3 and the second plug 4 by two connecting plates 7;

[0043] Flanges 8 are fixedly provided on the outer walls of both the male head 5 and the female head 6 in the circumferential direction. A limiting mechanism is located between the two flanges 8. The limiting mechanism includes several adjusting bolts 9 and several display components. Several adjusting bolts 9 are equally spaced on the flanges 8 of the female head 6. One end of each adjusting bolt 9 is threadedly connected to the flange 8 of the female head 6, and the other end of each adjusting bolt 9 is pressed against the flange 8 of the male head 5. Each display component is located next to one adjusting bolt 9.

[0044] A conical positioning boss 10 is fixedly provided on the outer wall of the male head 5. A conical positioning groove 11 is provided at the end of the female head 6 near the male head 5 for the conical positioning boss 10 to be inserted. An anti-detachment mechanism is provided between the conical positioning boss 10 and the conical positioning groove 11. The anti-detachment mechanism includes two wedge-shaped buckles 12 and two sliding components. A positioning rod 13 is fixedly provided inside the conical positioning groove 11. A positioning groove 14 is provided at the end of the conical positioning boss 10 away from the male head 5 for the positioning rod 13 to be inserted. The two sliding components are symmetrically arranged on the inner wall of the conical positioning boss 10. Each wedge-shaped buckle 12 is fixedly provided on one sliding component.

[0045] Reference Figures 1 to 6 As shown, a gap 15 is provided between the conical positioning boss 10 and the conical positioning groove 11. Preferably, the width of the gap 15 is 1-2mm, which allows the conical positioning boss 10 to adjust the insertion angle in real time during the insertion into the conical positioning groove 11, so that the conical positioning boss 10 can be quickly and automatically aligned after being in place, thereby improving the docking accuracy.

[0046] Reference Figures 1 to 6As shown, several circular guide rails 16 are evenly spaced on the outer wall of the flange 8 of the female connector 6, and each circular guide rail 16 is fixedly connected to the flange 8 of the female connector 6. Each circular guide rail 16 has a sliding arc-shaped slider 17, and each arc-shaped slider 17 has an installation plate 18 inserted into its outer wall. When connecting the first pipe pile 1 and the second pipe pile 2, the first plug 3 and the second plug 4 are first inserted into the interior of the first pipe pile 1 and the second pipe pile 2 respectively. Since the male connector 5 and the female connector 6 are fixedly connected to one end of the outer wall of the first plug 3 and the second plug 4 through two connecting plates 7 respectively, the male connector 5 and the female connector 6 are connected to the first pipe pile 1 and the second pipe pile 2 respectively. Then, the conical positioning boss 10 on the outer wall of the male connector 5... Insert the female head 6 into the conical positioning groove 11 to mate the male head 5 with the female head 6. Then, manually rotate the adjusting bolt 9 by grasping the handle 23. Since one end of each adjusting bolt 9 is threaded to the flange 8 of the female head 6, the other end of each adjusting bolt 9 is pressed against the flange 8 of the male head 5, controlling the insertion depth of the joint and preventing excessive compression. It should be noted that the circular slide rail and the arc-shaped slider 17 are designed to ensure that even when the indicator rod 19 on the outer wall of the adjusting bolt 9 is not facing the scale plate 20 after rotation, the arc-shaped slider 17 can still drive the mounting plate 18 and the scale plate 20 to slide towards the indicator rod 19, always ensuring that the indicator rod 19 can accurately measure the extension and retraction stroke of the adjusting bolt 9.

[0047] Reference Figures 1 to 6 As shown, each display component includes an indicator rod 19 and a scale plate 20. A protrusion 21 is fixed to the end of each adjusting bolt 9 furthest from the male connector 5. The indicator rod 19 is fixed to the outer wall of the protrusion 21. The scale plate 20 is fixed to the mounting plate 18, with the indicator rod 19 facing the scale plate 20. When the worker rotates the adjusting bolt 9 using the handle 23, the adjusting bolt 9 rotates in real time via the indicator rod 19 on the protrusion 21. When the adjusting bolt 9 is in place, the indicator rod 19 stops rotating. By observing the scale value pointed to by the indicator rod 19 on the scale plate 20 and comparing it with the initial scale value, the worker can determine the extension stroke of the adjusting bolt 9, i.e., the clamping distance to the male connector 5 connecting plate. By designing the display component, it can be ensured that several adjusting bolts 9 maintain a consistent extension stroke, i.e., that the clamping force of several adjusting bolts 9 on the male connector 5 flange 8 is uniform, thereby ensuring the connection accuracy of this joint, avoiding stress concentration caused by excessive insertion, and improving the overall load-bearing capacity of this joint.

[0048] Reference Figures 1 to 6 As shown, each protrusion 21 has a handle 23 fixedly provided on its outer wall by a connecting rod 22. The handle 23 is easy for people to grip, so that workers can easily grip the handle 23 in real time to adjust the extension and retraction stroke of the adjusting bolt 9.

[0049] Reference Figures 1 to 6As shown, each sliding assembly includes a clamping spring 24, a flange 25, and a sliding rod 26. Two symmetrically arranged grooves 27 are provided on the inner wall of the conical positioning boss 10. Each wedge-shaped latch 12 is slidably connected to one groove 27. Two symmetrically arranged sliding holes 28 are provided on the inner wall of the conical positioning boss 10. The flange 25 is slidably disposed inside one of the sliding holes 28. The sliding rod 26 is fixedly disposed at one end of the wedge-shaped latch 12, and the flange 25 is fixedly connected to the sliding rod 26. Each sliding hole 28 communicates with one groove 27. The clamping spring 24 is sleeved on the end of the sliding rod 26 away from the wedge-shaped latch 12. The outer wall of the flange 25 and the inner wall of the sliding hole 28 respectively abut against the two ends of the clamping spring 24. When the adjusting bolt 9 extends towards the male head 5 flange 8, that is, when the female head 6 drives the positioning rod 13 to insert into the positioning groove 14 on the conical positioning boss 10, the end of the positioning rod 13 abuts against the wedge-shaped latch 12. The inclined edge abuts against the wedge-shaped buckle 12, causing it to slide away from the positioning rod 13 inside the sliding groove 27. Since the outer wall of the flange 25 and the inner wall of the sliding hole 28 abut against the two ends of the clamping spring 24, the clamping spring 24 is driven from the initial state to the contracted state by the sliding rod 26 and the flange 25. When the adjusting bolt 9 is in place, that is, when the end of the adjusting bolt 9 away from the handle 23 abuts against the flange 8 of the male head 5, the wedge-shaped buckle 12 will align with one of the wedge-shaped grooves 30. Under the reset action of the clamping spring 24, the wedge-shaped buckle 12 is pushed into the corresponding wedge-shaped groove 30 by the sliding rod 26, thereby locking the conical positioning boss 10 against the positioning rod 13, and thus locking the male head 5 and the female head 6. This prevents the first pipe pile 1 and the second pipe pile 2 from separating during construction after docking, which helps to improve the firmness of the joint.

[0050] Reference Figures 1 to 6 As shown, the end of the positioning rod 13 away from the female head 6 is provided with a first oblique angle 29. The first oblique angle 29 facilitates the quick contact of the wedge-shaped buckle 12 when the end of the positioning rod 13 away from the female head 6 contacts the oblique edge on the outer wall of the wedge-shaped buckle 12, pushing it into the sliding groove 27, thereby improving the insertion speed of the positioning rod 13 and the positioning groove 14.

[0051] Reference Figures 1 to 6 As shown, several wedge-shaped slots 30 are evenly spaced on the outer wall of the positioning rod 13 in the circumferential direction. Two wedge-shaped buckles 12 engage with two of the wedge-shaped slots 30. The several equally spaced wedge-shaped slots 30 are evenly distributed in two rows, so that when the tightening force of the adjusting bolt 9 against the male flange 8 of the male head 5 is controlled, two wedge-shaped buckles 12 are always engaged with two of the wedge-shaped slots 30. That is, when the tightening force of the adjusting bolt 9 against the male flange 8 of the male head 5 is controlled, the positioning rod 13 and the positioning groove 14 on the conical positioning boss 10 are always firmly connected, which improves the flexibility and practicality of this joint.

[0052] Reference Figures 1 to 6 As shown, the outer walls of the first plug 3 and the second plug 4 are both provided with a second bevel 31. The second bevel 31 on the outer walls of the first plug 3 and the second plug 4 is designed to facilitate the quick insertion of the first plug 3 and the second plug 4 into the interior of the first pipe pile 1 and the second pipe pile 2, thereby improving the connection speed between the male plug 5 and the female plug 6 and the first pipe pile 1 and the second pipe pile 2, and further improving the connection speed of the male plug 5 and the female plug 6.

[0053] Reference Figures 1 to 6 As shown, a positioning bolt 32 is fixed on the outer wall of the male head 5. The positioning bolt 32 is threadedly connected to the conical positioning boss 10. The positioning bolt 32 is designed to realize the disassembly and assembly function of the conical positioning boss 10 and the male head 5. That is, when the conical positioning boss 10 on the male head 5 is deformed by collision during construction or transportation, it can be quickly removed and replaced without discarding the entire joint, reducing the cost of use and without delaying construction efficiency.
