[0005] Firstly, the existing pipe pile die is closed by arranging a plurality of slot bodies on the connecting plate during die closing, and the upper die and the lower die are closed by inserting the bolt assembly, and with long-time die opening and closing, the arrangement of the slot body reduces the strength of the connecting plate, thereby affecting the stability of the upper die and the lower die during die closing.

[0006] Secondly, during the pouring of concrete, part of the concrete will scatter on the butt joint surface of the lower die, which leads to the existence of gaps between the upper die and the lower die after die closing due to the existence of concrete at the butt joint part, and the phenomenon of material leakage is prone to occur.

[0007] From the above, it can be seen that the prior art obviously has inconvenience and defects in actual use, so it is necessary to improve. UTILITY MODEL CONTENTS

[0008] To address the shortcomings of existing technologies, this utility model provides a fully automatic pipe pile mold barrel forming equipment. This equipment solves the problem that in traditional pipe pile molds, several grooves are opened side by side on a connecting plate during mold closing. The upper and lower molds are closed by inserting bolt assemblies. However, with prolonged use of mold opening and closing, the opening of the grooves reduces the strength of the connecting plate, thereby affecting the stability of the upper and lower molds during the mold closing process.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A fully automatic pipe pile mold barrel forming equipment includes a lower mold shell and an upper mold shell arranged in a semi-circular shape. A lower mold connecting plate is fixedly connected to the outer side of the mating surface of the lower mold shell, and an upper mold connecting plate is fixedly connected to the outer side of the mating surface of the upper mold shell.

[0011] A swingable self-cleaning scraper is hinged to the lower surface of the upper mold connecting plate. The lower surface of the self-cleaning scraper is in frictional contact with the mating surface of the lower mold shell and the upper surface of the lower mold connecting plate.

[0012] The lower mold connecting plate is hinged to a swing frame, and a number of bolt assemblies are arranged side by side on the swing frame along the axial direction of the lower mold shell, and the bolt assemblies abut against the upper mold connecting plate.

[0013] As an optimized solution, the self-cleaning scraper is a rubber plate.

[0014] As an optimized solution, the bolt assembly includes a bolt threaded onto the swing frame, the end of which abuts against the upper surface of the upper mold connecting plate via a preload structure.

[0015] As an optimized solution, the pre-tightening structure includes a turntable fixed to the end of the bolt, a compression spring fixed to the rotating end of the turntable, a pressure plate fixed to the lower end of the compression spring, and the pressure plate abutting against the upper surface of the upper mold connecting plate.

[0016] As an optimized solution, the swing frame includes a lower horizontal plate hinged to the lower surface of the lower mold connecting plate, a side plate is fixed vertically upward at the outer end of the lower horizontal plate, and an upper horizontal plate is fixed horizontally at the upper end of the side plate.

[0017] As an optimized solution, the bolt is threaded onto the upper horizontal plate.

[0018] As an optimized solution, a hinge seat is fixedly connected to the outer wall of the upper mold connecting plate, and the self-cleaning scraper is hinged to the hinge seat.

[0019] As an optimized solution, a limiting rod is fixedly connected to the lower end of the hinge seat, and a limiting protrusion is fixedly connected to the end of the self-cleaning scraper. When the limiting rod abuts against the limiting protrusion, the self-cleaning scraper tilts towards the lower mold connecting plate.

[0020] As an optimized solution, the two ends of the upper mold shell are respectively fixed with upper support rings arranged in a semi-circular shape, and the top of the upper support rings is provided with a lifting hole.

[0021] As an optimized solution, the two ends of the lower mold shell are respectively fixed with a lower support ring arranged in a semi-circular shape.

[0022] Compared with the prior art, the beneficial effects of this utility model are:

[0023] By setting lifting holes in the upper support ring, the upper mold shell can be lifted. The self-cleaning scraper will swing freely downward under its own weight. When the limiting rod abuts against the limiting protrusion, the swing angle of the self-cleaning scraper is positioned. As the upper mold shell descends, the self-cleaning scraper abuts against the lower mold connecting plate. As the upper mold shell continues to descend, the self-cleaning scraper will swing to the center of the lower mold shell, thereby scraping the concrete scattered on the lower mold connecting plate and the lower mold shell mating surface into the lower mold shell, cleaning the concrete, ensuring the tightness of the upper and lower mold after mating, and preventing concrete leakage.

[0024] The self-cleaning scraper is made of rubber. After the upper and lower molds are connected, the self-cleaning scraper is located between the upper and lower molds. The self-cleaning scraper is squeezed and deformed, and its flexibility further improves the tightness between the upper and lower molds.

[0025] The upper mold connecting plate and the lower mold connecting plate are fixed by hinged swing frame on the lower mold connecting plate and bolt assembly on the swing frame. This overcomes the problem of strength being affected by the opening of several grooves in the upper mold connecting plate and the lower mold connecting plate in the traditional technology, and ensures the stability of the upper mold and the lower mold.

[0026] The bolt assembly is equipped with a pre-tightening structure, and a compression spring can be used to assist in pressing the upper mold connecting plate and the lower mold connecting plate together, thereby increasing the pre-tightening force. Attached Figure Description

Detailed Implementation

[0032] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0033] like Figs. 1 to 3 As shown, the fully automatic pipe pile mold barrel forming equipment includes a lower mold shell 1 and an upper mold shell 3 arranged in a semi-circular shape. A lower mold connecting plate 6 is fixedly connected to the outer side of the mating surface of the lower mold shell 1, and an upper mold connecting plate 7 is fixedly connected to the outer side of the mating surface of the upper mold shell 3.

[0034] A self-cleaning scraper 8 with a swinging configuration is hinged to the lower surface of the upper mold connecting plate 7. The lower surface of the self-cleaning scraper 8 is in frictional contact with the mating surface of the lower mold shell 1 and the upper surface of the lower mold connecting plate 6.

[0035] The lower mold connecting plate 6 is hinged to a swing frame 9. Several bolt assemblies are arranged side by side on the swing frame 9 along the axial direction of the lower mold shell 1. The bolt assemblies abut against the upper mold connecting plate 7.

[0036] The self-cleaning scraper 8 is made of rubber.

[0037] The bolt assembly includes a bolt 10 threaded onto the swing frame 9, the end of which abuts against the upper surface of the upper mold connecting plate 7 via a pre-tightening structure.

[0038] The pre-tightening structure includes a turntable 11 fixed to the end of the bolt 10. A compression spring 12 is fixed to the rotating end of the turntable 11. A pressure plate 13 is fixed to the lower end of the compression spring 12. The pressure plate 13 abuts against the upper surface of the upper mold connecting plate 7.

[0039] The swing frame 9 includes a lower horizontal plate hinged to the lower surface of the lower mold connecting plate 6, a side plate fixed vertically upward at the outer end of the lower horizontal plate, and an upper horizontal plate fixed horizontally at the upper end of the side plate.

[0040] Bolt 10 is threaded onto the upper horizontal plate.

[0041] A hinge seat 14 is fixedly connected to the outer wall of the upper mold connecting plate 7, and the self-cleaning scraper plate 8 is hinged to the hinge seat 14.

[0042] A limiting rod 15 is fixedly connected to the lower end of the hinge seat 14, and a limiting protrusion 16 is fixedly connected to the end of the scraping plate 8. When the limiting rod 15 abuts against the limiting protrusion 16, the scraping plate 8 tilts towards the lower mold connecting plate 6.

[0043] The upper mold shell 3 has a semi-circular upper support ring 4 fixed to both ends, and the top of the upper support ring 4 has a lifting hole 5.

[0044] The lower mold shell 1 has semi-circular lower support rings 2 fixed to both ends.

[0045] The working principle of this device is as follows:

[0046] By setting the lifting hole 5 in the upper support ring 4, the upper mold shell 3 can be lifted. The self-cleaning scraper 8 will swing freely downward under its own weight. When the limiting rod 15 abuts against the limiting protrusion 16, the swing angle of the self-cleaning scraper 8 is positioned. As the upper mold shell 3 descends, the self-cleaning scraper 8 abuts against the lower mold connecting plate 6. As the upper mold shell 3 continues to descend, the self-cleaning scraper 8 will swing to the center position of the lower mold shell 1, thereby scraping the concrete scattered on the mating surface of the lower mold connecting plate 6 and the lower mold shell 1 into the interior of the lower mold shell 1, thus cleaning the concrete and ensuring the tightness of the upper and lower molds after docking, preventing concrete leakage.

[0047] The self-cleaning scraper plate 8 is a rubber plate, which allows the upper and lower molds to be connected. The self-cleaning scraper plate 8 is located between the upper and lower molds, and the self-cleaning scraper plate 8 is squeezed and deformed. Its flexibility further improves the tightness between the upper and lower molds.

[0048] The upper mold connecting plate 7 and the lower mold connecting plate 6 are fixed by hinged swing frame 9 and bolt 10 assembly is set on swing frame 9. This overcomes the problem of the upper mold connecting plate 7 and the lower mold connecting plate 6 having several grooves in the traditional technology, which affects the strength and ensures the stability of the upper mold and the lower mold.

[0049] The bolt 10 assembly is equipped with a pre-tightening structure, and the compression spring 12 can assist in pressing the upper mold connecting plate 7 and the lower mold connecting plate 6 to increase the pre-tightening force.

[0050] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the 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 or all of the technical features.
