Description

Technical Field

[0001] The invention relates to the technical field of disassembly and assembly of pipe pile moulds, in particular to an end plate disassembly and assembly machine for disassembly and assembly of pipe pile moulds. Background Art

[0002] In the pipe pile production process, the assembly and disassembly of the pipe pile mold (especially the sealing and removal of the end plate) is a key link affecting production efficiency and product quality. Currently, traditional pipe pile molds have the following technical defects: Low clamping efficiency and poor stability: Traditional pipe pile molds are mostly clamped by manual bolt tightening or single cylinder drive. The clamping process is time-consuming (clamping a single set of molds takes 3-5 minutes), which makes it difficult to adapt to large-scale production needs.

[0003] Insufficient positioning accuracy of steel bar skeleton: The steel bar skeleton needs to be manually carried and placed into the mold barrel. Due to positioning deviation, the skeleton may easily tilt or collide with the inner wall of the mold, affecting the structural strength of the pipe pile. Although some equipment uses core rods to assist in positioning, the coaxiality error between the core rod and the mold barrel is large (often exceeding 1mm), further aggravating the positioning deviation.

[0004] Poor coordination between end plate sealing and pile mold rotation: The end plates of pipe pile molds are often fixed structures and cannot rotate synchronously with the mold, which affects the centrifugal effect during concrete pouring (such as uneven concrete density). To address this, we have launched an end plate disassembly and assembly machine for pipe pile molds. Summary of the Invention

[0022] The bottom support member includes a lifting seat 29 connected to the cavity by a first return spring 33, two sets of support shafts movably connected to the upper end of the lifting seat 29 by a bracket plate 37, a support cylinder 26 fixed to the support shaft, a first pulley 48 fixed in the middle of a set of support shafts, a servo motor 38 fixed in the middle of the upper end of the lifting seat 29, a second pulley 40 fixed to the output end of the servo motor 38, and a belt 39 connecting the first pulley 48 and the second pulley 40; The outer surface of the pile mold tube 8 is provided with a plurality of groups of reinforcing rings 11, and two groups of supporting tubes 26 are supported on the bottom of the pile mold tube 8, and the two groups of supporting tubes 26 are located between the two groups of reinforcing rings 11 in the middle (such as Figure 11 As shown), the top ends of the pipe pile mold tube 8 are provided with hanging rings 12; U-shaped seats 20 are symmetrically fixed on both sides of the upper part of the U-shaped fixing seat 2; The top clamping member includes a rotating cylinder 22 movably connected to the inside of the U-shaped seat 20 by a pin rod 30, a clamping cylinder 25 movably connected to the inner side of the rotating cylinder 22 by a U-shaped frame 24, and a rotating arm 23 connected to the outer side of the rotating cylinder 22, and a connecting groove 42 is provided on the rotating arm 23.

[0023] A vertical sliding block 32 is provided on the side wall of the cavity at the bottom of the U-shaped fixing seat 2 , and a sliding groove 34 for slidingly connecting the vertical sliding block 32 is provided on the side of the lifting seat 29 .

[0024] The linkage assembly includes a first piston 36 connected to the middle part of the lower end of the lifting seat 29 by a first piston rod 35, a main cylinder body 31 fixed in the middle of the cavity, a secondary cylinder body 19 connected to both sides of the bottom of the main cylinder body 31 by a connecting pipe 28, a second piston 46 disposed inside the secondary cylinder body 19, an internally threaded barrel 44 connected to the second piston rod 45 at the top of the second piston 46, a U-shaped connector 43 fixed to the top of the internally threaded barrel 44, and a connecting pin 41 fixed in the middle of the U-shaped connector 43; The first piston 36 is disposed in the master cylinder 31 , and the top of the first piston rod 35 extends through the top of the master cylinder 31 ; The auxiliary cylinder 19 is fixed to the bottom of the U-shaped seat 20. The top of the second piston rod 45 passes through the auxiliary cylinder 19 and the U-shaped seat 20 and is screwed to the internal threaded tube 44. A second return spring 47 is provided inside the auxiliary cylinder 19 and is sleeved on the second piston rod 45. The second return spring 47 is located between the top wall of the auxiliary cylinder 19 and the top of the second piston 46. The connecting pin 41 passes through the corresponding connecting slot 42 .

[0025] Gravity-triggered automatic clamping: The weight of the pile mold barrel 8 is used to drive the lifting seat 29 downward, and the top clamping parts are automatically clamped through the hydraulic linkage assembly (main cylinder 31, auxiliary cylinder 19). No additional power control is required, which saves energy and has high clamping efficiency.

[0026] Cushioning of hydraulic linkage: The hydraulic oil in the main cylinder 31 and the auxiliary cylinder 19 can cushion the impact force during clamping, avoiding damage to the mold barrel or equipment caused by rigid contact.

[0027] The first return spring 33 and the second return spring 47 ensure that the clamping and fixing assembly is automatically reset after the pile mold barrel 8 is removed, without the need for manual intervention, thereby improving operational safety.

[0028] Symmetrical clamping structure: The clamping cylinders 25 on both sides act synchronously to ensure that the pile mold cylinder 8 is evenly stressed, avoiding deformation caused by unilateral clamping, and is suitable for mold cylinders of different diameters (compatibility is achieved by adjusting the clamping stroke).

[0029] Rotatable support design: The support cylinder 26 is driven to rotate by the servo motor 38 to match the rotation requirements of the pile mold cylinder 8. No additional rotation mechanism is required, which simplifies the equipment structure and reduces the failure rate.

[0030] Under the action of the gravity of the pipe pile mold tube 8 itself, the clamping and fixing assembly realizes the clamping and fixing of the pipe pile mold tube 8, and the clamping and fixing assembly is also used to drive the pipe pile mold tube 8 to rotate; The upper end of the base 1 is also provided with a movable first movable seat 3, a second movable seat 4 and a third movable seat 7; The front and rear parts of the upper end of the base 1 are respectively provided with a front track 5 and a rear track 6, and the clamping and fixing components are located between the front track 5 and the rear track 6; the second movable seat 4 and the first movable seat 3 are slidably connected to the front track 5 in a front-to-back manner, and the third movable seat 7 is slidably connected to the rear track 6.

[0031] The tracks move independently: the first moving seat 3 and the second moving seat 4 slide along the front track 5, and the third moving seat 7 slides along the rear track 6. The movements of each component do not interfere with each other, which facilitates the step-by-step operations of placing the steel skeleton 18, positioning the core rod shaft 15, and sealing the end cover, thereby improving space utilization.

[0032] Precise alignment: The track guide ensures the linear motion accuracy of the moving seat, so that the coaxiality error between the core rod shaft 15 and the pipe pile mold tube 8 is ≤0.5mm, avoiding collision when the steel skeleton 18 is placed, and ensuring product quality.

[0033] The first movable seat 3 is used to place the steel bar skeleton 18, and a U-shaped groove is provided on the upper portion of the first movable seat 3 for placing the steel bar skeleton 18; The steel frame 18 is sleeved on the outside of the core rod assembly on the second movable seat 4; The core rod assembly includes a core rod shaft 15 fixed to the rear end of the second movable seat 4 and an abutment plate 16 fixed to the front of the core rod shaft 15 .

[0034] The abutment plate 16 at the front end of the core rod shaft 15 limits the axial displacement of the steel skeleton 18, and the rear end is locked by the nut 10 to ensure that the steel skeleton 18 does not shake during the pouring process, thereby improving the structural strength of the pipe pile.

[0035] The core rod shaft 15 runs through the entire pipe pile mold tube 8, taking into account the positioning of the steel skeleton 18 and the locking function of the end cover, reducing redundant components and reducing the weight of the equipment.

[0036] The core rod assembly is used to drive the steel bar skeleton 18 into the pile mold tube 8; The first movable seat 3 is also provided with an openable and closable end cover assembly; The retractable end cover assembly includes a front cover 14 movably connected to both sides of the rear end of the U-shaped groove by a pin 142. The rear end of the front cover 14 is provided with a semicircular groove 143 for sleeved on the outer front end of the pipe pile mold tube 8. The middle part of the front cover 14 is provided with a semicircular hole 141. A connecting ear 144 is provided on the top of the front end cover 14. After the two groups of connecting ears 144 are fixed with bolts, the two groups of front end covers 14 are closed to achieve the sleeve connection and sealing of the front end of the pipe pile mold tube 8.

[0037] Openable and closable front end cover: The two sets of front end covers 14 are movably connected by a pin shaft 142, and form a complete sealing structure when closed, which is suitable for pipe pile mold tubes 8 of different lengths, and the bolt connection facilitates quick disassembly and assembly, which is suitable for mass production scenarios.

[0038] After the openable and closable end cover assembly is closed, the front end of the pipe pile mold tube 8 is sleeved and sealed.

[0039] The third movable seat 7 is provided with a rotatable end cover assembly; The rotatable end cap assembly includes a rotating base 49 that passes through the opening on the third movable base 7, a bearing 52 embedded in the opening and sleeved on the outside of the rotating base 49, a retaining ring 51 that extends out of the opening at the rear end of the rotating base 49 and is fixed thereto, and an internally threaded ring 53 that is screwed onto the outside of the front of the rotating base 49. The rear end of the pipe pile mold tube 8 extends into the concave circular groove 17 at the front end of the rotating seat 49, and a reserved hole 50 for passing the core rod shaft 15 is provided in the middle of the concave circular groove 17. The rear end of the core rod shaft 15 extends out of the reserved hole 50 and is locked and fixed with the nut 10.

[0040] Rotatable rear end cover: The rotating seat 49 is connected to the third movable seat 7 through the bearing 52, allowing the rear end cover to rotate synchronously when the pile mold barrel 8 rotates, avoiding friction and wear between the end cover and the pile mold barrel 8, and extending the life of the equipment.

[0041] When the rear end of the core rod assembly extends through the rotatable end cover assembly and is locked with the nut 10, the rotatable end cover assembly is sleeved and sealed on the rear end of the pipe pile mold tube 8.

[0042] Specifically, when using: Clamping and fixing of the pipe pile mold tube 8: The crane uses a steel rope to connect to the lifting ring 12 and lifts the pipe pile mold tube 8, and places the pipe pile mold tube 8 on the support tube 26 of the clamping and fixing assembly. Under the action of its own gravity, the lifting seat 29 compresses the first return spring 33 and moves downward, driving the first piston rod 35 to push the first piston 36 in the main cylinder body 31 to move downward, so that the hydraulic oil in the main cylinder body 31 flows into the auxiliary cylinder bodies 19 on both sides through the connecting pipe 28.

[0043] The hydraulic oil pushes the second piston 46 in the auxiliary cylinder 19 to move upward, and the second piston rod 45 drives the internal threaded cylinder 44 and the U-shaped connector 43 to rise. The connecting pin 41 slides along the connecting groove 42 of the rotating arm 23, driving the rotating cylinder 22 to rotate around the pin rod 30, so that the inner clamping cylinder 25 swings downward and clamps the top of the pipe pile mold cylinder 8, completing the automatic clamping.

[0044] Placement of the steel skeleton 18 and positioning of the core rod assembly: Place the steel frame 18 in the U-shaped groove of the first movable seat 3, and move the second movable seat 4 backward along the front track 5, so that the steel frame 18 is sleeved on the outside of the core shaft 15 of the second movable seat 4, and the abutment plate 16 at the front end of the core shaft 15 abuts against the front end of the steel frame 18 to achieve positioning (such as Figure 16 shown); The second movable seat 4 continues to move backward along the front track 5, so that the second movable seat 4 pushes the first movable seat 3 to move backward to the position shown in FIG. Figure 2 and 17 At the position shown, the core rod shaft 15 extends from the rear of the pile mold tube 8, and the abutment plate 16 abuts against the steel skeleton 18 and enters into the pile mold tube 8.

[0045] Sealing and locking of the pile mold tube 8: Front end sealing: Rotate the two sets of front end covers 14 on the first movable seat 3 so that their semicircular grooves 143 are sleeved on the outer front end of the pipe pile mold tube 8, and are fixed by connecting ears 144 and bolts. After closing, the front end cover 14 forms a complete circle, sealing the front end of the pipe pile mold tube 8, and the core rod shaft 15 passes through the semicircular hole 141 of the front end cover 14.

[0046] When the pile mold tube 8 rotates, the two sets of front end covers 14 will not rotate with it, but the front end covers 14 after the two sets of front end covers 14 are closed form a complete circle, blocking the front end of the pile mold tube 8, which can neither hinder the rotation of the pile mold tube 8 nor block the front end of the pile mold tube 8.

[0047] Rear end blocking: push the third movable seat 7 to move forward along the rear track 6, so that the rear end of the pipe pile mold tube 8 extends into the concave circular groove 17 of the rotating seat 49, and the rear end of the core rod shaft 15 passes through the reserved hole 50 and is locked with the nut 10. The rotating seat 49 is connected to the third movable seat 7 through the bearing 52 and can rotate synchronously with the pipe pile mold tube 8.

[0048] The upper end of the pipe pile mold tube 8 is also provided with a pouring pipe for pouring concrete.

[0049] Rotation operation of the pipe pile mold barrel 8: Start the servo motor 38, and drive the first pulley 48 to rotate through the second pulley 40 and the belt 39, thereby driving the support shaft and a corresponding support cylinder 26 to rotate. Since the support cylinder 26 is in contact with the bottom of the pipe pile mold cylinder 8, the friction force drives the pipe pile mold cylinder 8 to rotate, which is convenient for subsequent concrete pouring or demoulding operations.

[0050] Reset and disassembly: Loosen the bolts of the front cover 14 and the nut 10 at the rear end of the core shaft 15, and reset the first movable seat 3, the second movable seat 4, and the third movable seat 7; the core shaft 15 drives the formed pipe pile to move out of the pipe pile mold tube 8, and then the core shaft 15 is pulled out from the inside of the formed pipe pile by moving the second movable seat 4; After the pile mold tube 8 is subsequently removed, the first return spring 33 pushes the lifting seat 29 upward, the hydraulic oil in the main cylinder 31 flows back, the second return spring 47 pushes the second piston 46 downward, the top clamping part is reset, and the disassembly is completed.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
