DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be understood that the present invention uses the terms "first", "second", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0027] like Figures 1 to 5 As shown, an embodiment of the present invention provides a flat pile extruder, which mainly includes a frame 1 and a propulsion mechanism. The frame 1 includes two side frames 101 arranged in parallel, a flat pile forming area 102 is provided between the two side frames 101, and the side frames 101 are provided with an opening for inserting the U-shaped stirrup 2 into the forming area 102, and the openings on the two side frames 101 are arranged opposite to each other, so that the two U-shaped stirrups 2 entering the forming area 102 through the openings on the two side frames 101 can overlap to form an annular stirrup 3 wrapped around the main reinforcement 7, and then form a steel skeleton of the flat pile with the main reinforcement 7 and the auxiliary reinforcement 8. As an optional solution, the overlap of the two U-shaped stirrups 2 can be welded to obtain better stability. The propulsion mechanism is arranged on the frame 1 to provide forward power.

[0028] Based on the above structure, on the one hand, the flat pile extruder provided in the embodiment of the present invention can use the propulsion force generated by the propulsion mechanism to move forward along the main reinforcement 7 and the auxiliary reinforcement 8, thereby realizing the automatic casting of the flat pile; on the other hand, the flat pile extruder is provided with relative openings on the two side frames 101, so that the two U-shaped stirrups 2 that enter the forming area 102 through the openings on the two side frames 101 can be overlapped to form an annular stirrup 3, thereby perfectly solving the problem that the stirrup insertion process and the concrete pouring process cannot be carried out synchronously, and successfully realizing the automatic production of flat piles, thereby improving the production efficiency of flat piles, shortening the production cycle of flat piles, reducing the labor of workers, reducing labor costs, and improving the forming quality of flat piles.

[0029] Furthermore, if Figures 1 to 5As shown, the flat pile extruder provided in the embodiment of the present invention also includes a hoop delivery mechanism 4, which includes a bottom plate 401, a hoop box 402, a hoop push plate 403 and a driving device 404; the bottom plate 401 is connected to the outer side of the side frame 101, and the hoop box 402 is arranged on the bottom plate 401 for placing the U-shaped hoop 2; the hoop box 402 is provided with a slide groove 4021 facing the opening, and the hoop push plate 403 is arranged in the slide groove 4021 and can reciprocate along the slide groove 4021, through which the hoop push plate 403 pushes the hoop in the hoop box 402 from the opening into the forming area 102; the driving device 404 is arranged above the hoop box 402, and the driving device 404 is provided with a telescopic member 4041 parallel to the slide groove 4021, and the telescopic member 4041 is connected to the push hoop plate 403, so that the push hoop plate 403 can be driven to move. Based on this, during the process of the flat pile extruder moving forward along the main reinforcement 7 and the auxiliary reinforcement 8, the stirrups stored in the stirrup box 402 can be automatically and continuously inserted into the forming area 102, so as to further improve the automation level of the flat pile extruder and reduce the workload of workers.

[0030] It should be noted that, in this embodiment, the driving device 404 is a linear reciprocating motor, and the telescopic member 4041 is a telescopic rod or a telescopic rack.

[0031] Optionally, in order to enable the stirrups in the stirrup box 402 to automatically enter the slide groove 4021, a support plate for supporting the U-shaped stirrups 2 is provided in the stirrup box 402. The support plate is inclined and its lower end extends to the slide groove 4021. Thus, when the stirrups in the slide groove 4021 are pushed into the forming area 102 by the push hoop plate 403, the next stirrup will slide into the slide groove 4021 along the support plate, waiting for the next push of the push hoop plate 403.

[0032] like Figures 1 to 3 As shown, the propulsion mechanism includes a propulsion motor 5, a gearbox 9 and a screw 6. The gearbox 9 is arranged between the two side frames 101 and in front of the forming area 102. The gearbox 9 is provided with a first hole 901 for the main reinforcement 7 to pass through and a second hole 902 for the auxiliary reinforcement 8 to pass through. A first mounting plate laid on the two side frames 101 is provided in front of the gearbox 9. The propulsion mechanism is fixed on the first mounting plate. The screw 6 is arranged in the forming area 102 and is connected to the propulsion mechanism through the gearbox 9. The flat pile extruder provided in the embodiment of the present invention can realize forward movement along the main reinforcement 7 and the auxiliary reinforcement 8 through the propulsion force generated by the screw 6 when mixing concrete.

[0033] Alternatively, if Figure 5As shown, in addition to the above-mentioned form, the propulsion mechanism can also adopt another form, that is, it includes a propulsion motor 5, a pushing and squeezing block 13 and a pushing and squeezing connecting rod 14. The propulsion motor 5 is mounted on the frame 1 through a first mounting plate. The pushing and squeezing block 13 can be slidably arranged between the two side frames 101 and is connected to the propulsion motor 5 through the pushing and squeezing connecting rod 14. The pushing and squeezing block 13 is provided with a first hole 901 for the main reinforcement 7 to pass through and a second hole 902 for the auxiliary reinforcement 8 to pass through. In this way, the flat pile extruder provided by the embodiment of the present invention can realize forward movement along the main reinforcement 7 and the auxiliary reinforcement 8 through the propulsion force generated by the pushing and squeezing block 13 when squeezing concrete. Of course, the above-mentioned propulsion motor 5 can also be replaced by a pushing cylinder. Since the technical effects produced are the same, they will not be repeated here.

[0034] Furthermore, if Figures 1 to 3 As shown, the flat pile extruder provided in the embodiment of the present invention further includes a hopper 10, a vibrator 11 and a counterweight 12. The hopper 10 is arranged above the screw 6, and is used to store concrete and inject concrete into the molding area 102 to achieve continuous pouring of concrete. A vibration plate laid on two side frames 101 is provided at the rear of the hopper 10, and the vibrator 11 is fixed on the vibration plate. Through the vibration generated by the vibrator 11, the concrete in the molding area 102 can be quickly molded. A second mounting plate laid on the two side frames 101 is provided at the rear of the vibrator 11, and the counterweight 12 is fixed on the second mounting plate to balance the front and rear weights of the entire flat pile extruder.

[0035] In addition, it should be pointed out that the flat pile extruder provided by the present invention can be used not only for producing flat piles, but also for producing prestressed hollow slabs or other concrete slabs.

[0036] In summary, the present invention provides a flat pile extruder, which improves the production efficiency of flat piles, shortens the production cycle of flat piles, reduces the workload of workers, reduces labor costs, and improves the molding quality of flat piles.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
