Description

Technical Field

[0001] The utility model relates to the technical field of box culvert production, and more specifically, to an integral prefabricated box culvert production device. Background Art

[0002] In modern urban infrastructure construction, box culverts, as an important drainage and passage structure, are in increasing demand. With the acceleration of urbanization, the quality and appearance requirements for box culverts are also increasing. Box culverts are required to have not only sufficient strength and stability, but also good sealing and durability.

[0003] Traditional mold designs are often tailored to specific box culvert sizes, making it difficult to quickly adjust the mold and flexibly adapt to production needs of varying specifications. This increases production costs and extends production cycles. Furthermore, during the box culvert forming process, mold stability directly impacts product quality and precision. Traditional mold connection methods can be unstable and prone to loosening, impacting the final product. Furthermore, mold removal and installation increase production costs and labor requirements. This device was developed to address these issues. Utility Model Content

[0025] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0026] In order to enable those skilled in the art to better understand the present application, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0027] Example:

[0028] Refer to the attached Figure 1 and Figure 3 The embodiment of the present invention is an integral prefabricated box culvert production device, comprising a receiving base 1, with mounting grooves 2 provided on the four sides of the top of the receiving base 1, and two mounting grooves 2 are provided on each side, and a connecting block 3 is slidably installed in the mounting groove 2, wherein the mounting groove 2 and the connecting block 3 are both rectangular structures, and an outer template 4 is fixedly installed on the top of the connecting block 3, and the cross-section of the inner end of the outer template 4 is an isosceles trapezoidal structure, and two adjacent outer templates 4 are in contact, thereby forming the external mold required in the box culvert production process.

[0029] Refer to the attached Figure 1 、 Figure 2 and Figure 4 The four sides of the outer template 4 are provided with connectors 5. The four corners of the top of the connector 5 are fixedly installed with a No. 1 lifting ring 13. When in use, the connector 5 is transported to the outside of the outer template 4 on the four sides by using external lifting equipment through the No. 1 lifting ring 13. The outer wall of the outer template 4 is fixedly installed with a limit block 6. The limit block 6 receives the connector 5 to limit the position of the connector 5. The limit block 6 is fixedly installed with a push-pull handle 14. The push-pull handle 14 is used to move the outer template 4. The connector 5 is used to achieve a stable connection between the outer template 4 and the receiving base 1, and at the same time facilitates the installation and removal of the outer template 4, thereby improving production efficiency and the reusability of the mold.

[0030] Refer to the attached Figure 1An inner template 7 is arranged between the four outer templates 4 on the four sides, and a No. 2 lifting ring 15 is fixedly installed at the four corners of the top of the inner template 7. Through the No. 2 lifting ring 15, the inner template 7 is transported to the space between the four outer templates 4 by using external lifting equipment when in use. The cross-section of the inner template 7 is in the shape of a "mouth".

[0031] Refer to the attached Figure 1 、 Figure 4 and Figure 5 A bracket 8 is fixedly installed on the top of the outer template 4, and a screw 9 is threadedly connected to the bracket 8. A step block 10 is fixedly installed on the inner end of the screw 9. A support plate 11 is provided on the inner side of the screw 9. The four side support plates 11 are all arranged inside the inner template 7, and the support plates 11 are made of aluminum alloy material. A stepped hole is provided on the support plate 11. The screw 9 is rotatably connected to the support plate 11 through the stepped block 10 and the stepped hole, thereby realizing the lateral movement of the support plate 11, which is convenient for moving the support plate 11 to the inside of the inner template 7 to fix the inner template 7. A handwheel 12 is fixedly installed on the outer end of the screw 9. When in use, the handwheel 12 is turned to realize the movement of the screw 9 and the support plate 11.

[0032] It should be noted that the inner wall surface of the outer template 4 and the outer wall surface of the inner template 7 are both coated with a wear-resistant coating. The wear-resistant coating is coated on the contact surface of the outer template 4 and the inner template 7, which effectively reduces the wear caused by friction during repeated use of the mold.

[0033] During the box culvert production process, the mounting groove 2 and the connecting block 3 are first used to realize the connection between the outer templates 4 on the four sides and the receiving base 1, and then the connecting piece 5 is transported by the lifting device so that the connecting piece 5 is sleeved on the outer templates 4 on the four sides to realize the connection between the outer templates 4 on the four sides, and then the hand wheel 12 is rotated to realize the movement of the screw 9 and the support plate 11 so that the support plate 11 is close to the outer template 4 to avoid the screw 9 and the support plate 11 from hindering the placement of the inner template 7, and then the lifting device is used to transport the inner template 7 between the outer templates 4 on the four sides, and the receiving base 1 receives the inner template 7, and at this time the support plate 11 is rotated. Make the support plate 11 face upward, and at the same time, turn the handwheel 12 to realize the inward movement of the screw 9 and the support plate 11. When the support plate 11 moves to the upper part of the inner template 7, turn the support plate 11 so that the support plate 11 faces downward. At this time, turn the handwheel 12 again. The handwheel 12 drives the screw 9 and the support plate 11 to move outward until the support plate 11 contacts the inner wall surface of the inner template 7, ensuring that the inner template 7 is in the middle position above the receiving base 1. The position of the inner template 7 can be determined. At this time, a cavity is formed between the inner template 7 and the outer templates 4 on the four sides, and mortar is injected into the cavity to realize the forming operation of the box culvert.

[0034] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
