Description

Technical Field

[0001] This utility model relates to the field of rectangular pile forming technology, specifically to a composite reinforced hollow rectangular pile and its casting and forming equipment. Background Technology

[0002] Rectangular hollow piles are an important form of pile foundation in building engineering. Their main function is to transfer the load of the superstructure to the lower structure, such as deep stable coatings or rock strata. Among them, composite reinforced hollow rectangular piles are widely used in related fields due to their advantages such as factory prefabrication, high strength and large bearing capacity.

[0003] However, the current process for manufacturing composite reinforced hollow rectangular piles is quite cumbersome. In the production of composite reinforced hollow rectangular piles, the composite reinforcing bars must first be transferred to a mold, then the hollow core is inserted into the mold. Subsequently, the concrete is poured into the mold by manual control of the pouring head. After pouring, a vibrator is used to compact the concrete slurry. After compaction, the hollow core is removed after the concrete has initially solidified. Demolding is then performed after the concrete has fully formed, often requiring the complete disassembly of the mold. All of the above processes require manual intervention, consuming a large amount of manpower, resulting in low production efficiency and high economic costs.

[0004] Based on this, this utility model designs a composite reinforced hollow rectangular pile and its casting equipment to solve the above problems. Utility Model Content

[0021] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-7A composite reinforced hollow rectangular pile includes a composite reinforced hollow rectangular pile body 5. The composite reinforced hollow rectangular pile body 5 has cross-distributed reinforcing bars fixedly connected inside, which enhance the strength of the composite reinforced hollow rectangular pile body 5.

[0022] Two sets of composite reinforced hollow rectangular piles 5 are connected on the side by rectangular pile grooves 52 and rectangular pile protrusions 53. The rectangular pile protrusions 53 are inserted into the rectangular pile grooves 52. The outer side of the rectangular pile protrusions 53 is chamfered and can play a guiding role.

[0023] In this utility model, the guiding function of the rectangular pile groove 52 and the rectangular pile protrusion 53 makes it easier to connect multiple sets of composite reinforced hollow rectangular piles 5 end to end, thereby facilitating subsequent welding and fixing, so as to improve the overall strength in slope anti-slip.

[0024] A casting and molding equipment for composite reinforced hollow rectangular piles includes an automatic casting vibration mechanism 2, a mold synchronous opening and closing mechanism 3, and an alignment auxiliary core pulling mechanism 4.

The synchronous opening and closing assembly is connected to the left mold 306 and the belt conveyor 1 respectively.

[0026] The left mold 306 is a U-shaped plate. The mold side plate 303 inside the left mold 306 is located on the right side of the left side wall of the left mold 306.

[0030] A mold groove 317 is provided on the right side wall of the right mold 307. The mold groove 317 is used to form a rectangular pile protrusion 53 on the composite reinforced hollow rectangular pile body 5 after subsequent casting.

[0031] When the right end of the left mold 306 is attached to the right mold 307, the mold side plate 303, the bottom surface of the right mold 307 and the side wall of the right mold 307 form a rectangular space with an opening at the top. The composite reinforced hollow rectangular pile 5 is formed by casting in this rectangular space.

[0032] The synchronous opening and closing assembly includes a driven moving frame 310, a roller connecting frame 312, a mold roller 313, a drive roller 314, and a drive moving frame 315. The driven moving frame 310 is fixedly connected to the left end of the left mold 306, and the drive moving frame 315 is fixedly connected to the outer shell of the belt conveyor 1.

[0033] The distance between the middle bottom surface of the driven moving frame 310 and the driven moving groove 311 and the left mold 306 is greater than the distance between the two bottom surfaces of the driven moving frame 310 and the driven moving groove 311 and the left mold 306.

Therefore, with the cooperation of the driven moving frame 310, the roller connecting frame 312, the mold roller 313, the drive roller 314 and the drive moving frame 315, when the left mold 306 reaches the middle of the upper end of the belt conveyor 1, it will move to the right relative to the right mold 307.

[0036] The alignment-type auxiliary core-pulling mechanism 4 includes a movable frame 401, a core-pulling connecting plate 403, a movable column 405, a connecting rod 406, a rotating block 407, a motor 408, a motor connecting plate 409, a core-pulling push block 410, and a core-pulling push plate 411. The movable frame 401 is fixedly connected to the upper end of the core-pulling connecting plate 403. The core-pulling connecting plate 403 has a core-pulling clearance hole 402 for avoiding the mold core during core pulling. The core-pulling connecting plate 403 has four sets of circumferentially arranged core-pulling limiting holes 404, which are located outside the core-pulling clearance holes 402. The four sets of movable columns 405 are slidably connected to each other. One end of each set of movable columns 405 is hinged to one end of each set of connecting rods 406. The other end of each set of movable columns 405 is fixedly connected to each set of core-pulling push blocks 410. The rotating block 407 is hinged to the other end of each set of connecting rods 406. The lower end of the motor connecting plate 409 is fixedly connected to the movable frame 401. The upper end of the motor connecting plate 409 is fixedly connected to the housing of the motor 408. The output end of the motor 408 is fixedly connected to the rotating block 407. The core-pulling push plate 411 is fixedly connected to the core-pulling push block 410. The core-pulling push plate 411 is used to clamp the mold core inward.

[0037] Two sets of laser emitters 305 are fixedly connected to the front end of the mold through hole 304 on the front side plate of the left mold 306. Light sensors are fixedly connected to the left and right ends of the core pulling connecting plate 403. The laser emitters 305 and the light sensors are positioned correspondingly. When the two are aligned, it is the position for core pulling.

[0038] The core-pulling push plate 411 is an arc-shaped plate.

[0039] The lower end of the mobile frame 401 is fixedly connected to the universal casters or to the transport vehicle, so that the core pulling operation can be performed after the core pulling push plate 411 holds and fixes the mold core inward.

[0040] In this invention, a square steel bar is first placed into the right mold 307 by a robotic arm. The belt conveyor 1 transports the right mold 307 from right to left. When it reaches the middle position, the drive roller 314 moves inward under the limiting action of the drive moving frame 315 and the drive moving groove 316. The drive roller 314 drives the roller connecting frame 312 and the mold roller 313 to move inward. The mold roller 313 moves under the limiting action of the driven moving frame 310 and the driven moving groove 311. The mold roller 313 causes the driven moving frame 310 and the driven moving groove 311 to move to the right. The rightward movement of the mold roller 313 drives the left mold 306 to move to the right. That is, the vertical limiting block 301 moves to the right in the vertical limiting groove 308, and the horizontal limiting block 302 moves to the right in the horizontal limiting groove 309. Thus, the left mold 306 will move relative to the left mold 306. As the right mold 307 moves to the right, the right end of the left mold 306 finally fits against the left end of the right mold 307. The mold side plate 303, the bottom surface of the right mold 307, and the side wall of the right mold 307 form a rectangular space with an opening at the top. When the left mold 306 and the right mold 307 reach the lower end of the automatic pouring vibration mechanism 2, the belt conveyor 1 stops moving and inserts the cylindrical mold core into it through the mold through hole 304. The cylinder 205 is started, pushing the vertical push plate 206 downward. The downward movement of the vertical push plate 206 drives the pouring head 207 downward. At this time, the external concrete is poured into the rectangular space by the pouring head 207. The linear module 201 pushes the horizontal moving slider 203 and the cylinder connecting plate 204 to move, thereby controlling the pouring head 207 to move back and forth for uniform pouring. At the same time as pouring, the vibrator 202 vibrates to make the concrete compact. After the pouring is completed, the cylinder 205 resets, driving the vertical push plate 206 and the pouring head 207 to reset. After the concrete is initially formed, the mold core can be pulled out. Push the moving frame 401 so that the laser emitter 305 corresponds to the light sensor and the mold core passes through the mold core clearance hole 402. At this time, the motor 408 on the motor connecting plate 409 is started. The motor 408 drives the rotating block 407 to rotate. The rotation of the rotating block 407 drives the connecting rod 406 to move. Under the limiting action of the core pulling limit hole 404, the connecting rod 406 drives the moving column 405 to move inward, thereby driving the core pulling push block 410 to move inward. The core pulling push plate 411 clamps and fixes the mold core inward. At this time, the mold core can be easily pulled out by pushing the moving frame 401 forward. After the core is extracted, wait for the concrete to complete its molding before demolding. At this time, the belt conveyor 1 starts, driving the left mold 306 and the right mold 307 to move to the left. With the cooperation of the driven moving frame 310, the driven moving groove 311, the roller connecting frame 312, the mold roller 313, the drive roller 314, the drive moving groove 316 and the drive moving frame 315, the left mold 306 will move to the left relative to the right mold 307, making demolding more convenient.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
