Description

Technical Field

[0001] The present invention belongs to the technical field of concrete molds, and particularly relates to a mold for manufacturing highly durable concrete pipes and a using method thereof. Background Art

[0002] Highly durable concrete pipes are a type of concrete pipes specifically designed to withstand harsh environmental conditions and are widely used in infrastructure construction such as urban drainage, sewage treatment, rainwater collection, and water supply. Based on traditional concrete pipes, these pipes have been optimized in special formulations and manufacturing processes, which can significantly improve their corrosion resistance, freeze-thaw resistance, impermeability, and chemical erosion resistance, and are particularly suitable for underground pipe systems and projects exposed to soil and water corrosion environments for a long time. Highly durable concrete pipes usually select high-strength cement, mineral admixtures, and additives, combined with advanced production technologies, to ensure their long-term stable performance in harsh natural environments.

[0003] When processing highly durable concrete pipes, operations such as backfilling and demolding are required. When the existing molds for manufacturing highly durable concrete pipes are demolded, since the molds are in a sealed state, it is impossible to quickly separate the highly durable concrete pipes during demolding, thus reducing the processing efficiency of highly durable concrete pipes. In addition, the current molds cannot change the specifications of the concrete pipes, resulting in a single specification of the concrete pipes and thus the single use of the molds. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide a mold for manufacturing highly durable concrete pipes and a using method thereof.

[0005] The technical solution adopted to solve the above technical problem is: A mold for manufacturing highly durable concrete pipes, including a main body, a driving mechanism is installed on the inner wall of the main body, and a base is rotatably connected to the outer wall of the driving mechanism;

[0006] One side of the main body is movably connected with a splicing plate, a feeding pipe is fixedly connected to the surface of the splicing plate, an adjusting mechanism is installed on the outer wall of the driving mechanism, two supporting mechanisms are installed on the outer wall of the driving mechanism, and a handle is fixedly connected to the other end of the driving mechanism.

[0007] Further, the driving mechanism includes a motor inserted and connected to one side of the base, a sleeve shaft is fixedly connected to the output end of the motor, a threaded rod is fixedly connected to the other end of the sleeve shaft, a rotating shaft is rotatably connected to the inner wall of the threaded rod, the outer walls of the sleeve shaft and the rotating shaft are rotatably connected to the base, and a handle is fixedly connected to the inside of the other end of the rotating shaft.

[0008] Through the above technical solution, during use, first select according to the specifications of the high-durability concrete pipe pile. The driving mechanism can be used in cooperation with other mechanisms for adjustment. The driving mechanism mainly provides a driving force to assist the normal progress of the adjustment work, and thus can help adjust the thickness of the concrete pipe pile. Specifically, use a lifting device to place the mold on the base, and then start the motor on one side of the base to drive the threaded rod at the other end of the sleeve shaft to rotate. When the threaded rod rotates, the entire device has a driving force. There is a bump on the outer walls of both the threaded rod and the rotating shaft for limiting with other components, so that the adjustment of the entire device can proceed smoothly.

[0009] Further, the adjustment mechanism includes a support ring rotatably connected to the outer wall of the threaded rod. A plurality of first connecting rods are rotatably connected to the outer wall of the support ring. Two fixing rings are fixedly connected to the outer wall of the rotating shaft. A plurality of second connecting rods are rotatably connected to the outer walls of the two fixing rings. The other ends of the plurality of first connecting rods are respectively rotatably connected to a first support plate. A plurality of springs are fixedly connected to the inner parts on both sides of the plurality of first support plates. The other ends of the plurality of springs are fixedly connected to a telescopic plate. The other ends of the plurality of second connecting rods are respectively rotatably connected to the corresponding first support plates.

[0010] Through the above technical solution, with the rotation of the driving mechanism, it will drive the adjustment mechanism to start operating. As the adjustment work progresses, the diameter will expand outward, and it can ensure that there is no leakage after the high-durability concrete is injected and the sealing state with other mechanisms. At the same time, after the concrete injection is completed, it can also be rotated to help the concrete be shaken evenly, and thus the smoothness of the surface of the concrete pipe pile can be achieved. Specifically, with the rotation of the threaded rod, it will drive the support ring on the outer wall of the threaded rod to move, and then drive a plurality of first connecting rods to jack up until the corresponding first support plates are jacked up by the plurality of first connecting rods. As the plurality of second connecting rods and the first connecting rods stand upright, they will expand outward. Then, a plurality of springs will expand outward to push out the telescopic plate. At this time, it will drive the first support plate to move to one side, and then the main body can be combined according to the adjustment position.

[0011] Further, the support mechanism includes a fixing plate movably connected to the outer wall of the rotating shaft. A circular plate is rotatably connected to the inside of the fixing plate. A plurality of arc-shaped grooves are formed in the inside of the circular plate. A plurality of support columns are slidably connected to the inside of the plurality of arc-shaped grooves. The other ends of the plurality of support columns are fixedly connected to a second support plate. Connecting grooves are provided on both sides of the plurality of second support plates. One of the support mechanisms is movably connected to the driving mechanism. The plurality of connecting grooves are respectively in pressing connection with the corresponding telescopic plates.

[0012] Through the above technical solution, under the condition that the adjusting mechanism is opened, the supporting mechanism can be combined and sealed at this time, thus forming a ring. Specifically, subsequently, under the limit of the bump on the threaded rod and the circular plate, the circular plate is driven to rotate. With the rotation, a plurality of support columns will slide on the corresponding arc-shaped grooves, and then the plurality of support columns will jack up until the corresponding second support plate is expanded to the required thickness of the concrete pipe. With the movement of the adjusting mechanism, the position of the rotating shaft can be adjusted at this time so that the second support plate and the first support plate can be fitted and aligned. One side of the second support plate and the first support plate has a limiting connection relationship with the plate on the other side of the main body. When the circular plate rotates and adjusts, since the limiting fixing plate does not rotate, the main body housing is then sleeved and the splicing plates are spliced, and then the material is injected. Through the detachment of the main body, air intake and shedding can be quickly carried out. During the overall rotation process, the main body and the supporting mechanism always move along with the rotation of the rotating shaft, and there will be a limit during the movement and it will not rotate with the rotation of the threaded rod.

[0013] A method for using a mold for making highly durable concrete pipes includes the following specific steps:

[0014] Step 1: Use a lifting device to place the mold on the base, and then start the motor on one side of the base to drive the threaded rod at the other end of the sleeve shaft to rotate. Subsequently, under the limit of the bump on the threaded rod and the circular plate, the circular plate is driven to rotate. With the rotation, a plurality of support columns will slide on the corresponding arc-shaped grooves, and then the plurality of support columns will jack up until the corresponding second support plate is expanded to the required thickness of the concrete pipe. This operation is completed.

[0015] Step 2: With the rotation of the threaded rod, the support ring on the outer wall of the threaded rod will be driven to move, thereby driving a plurality of first connecting rods to jack up until the plurality of first connecting rods jack up the corresponding first support plate. With the movement of the second support plate, at this time, the distance between the first support plate and the second support plate is opened, and then a plurality of springs will expand outwards to push out the telescopic plate to contact the connecting grooves on both sides of the plurality of second support plates.

[0016] Step 3: When the mold adjustment is completed, at this time, according to the opened position, the two main bodies are combined and installed on the base, and then highly durable concrete is put in from the feeding pipe. The concrete will flow into the space between the main body, the first support plate and the second support plate. When the concrete is filled, manually hold the handle and rotate it. After solidification, use a lifting device to detach it. Thus, the production of highly durable concrete pipes is completed.

[0017] The beneficial effects of the present invention are as follows: (1) By designing a driving mechanism, an adjusting mechanism, and a supporting mechanism, the present invention can be selected according to the required specifications of high-durability concrete pipe piles, increasing the applicability of the concrete pipe mold and making it more convenient to disassemble; (2) By designing a driving mechanism, the high-durability concrete pipe supporting mold can be driven by a power source during use, ensuring that the mold can be adjusted during use; (3) By designing an adjusting mechanism and a supporting mechanism, the thickness can be selected according to the required specifications, and detachment can be better achieved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] As Figures 1 - 7As shown in the figure, a mold for making high-durability concrete pipes in this embodiment includes a main body 1. A driving mechanism 2 is installed on the inner wall of the main body 1. The driving mechanism 2 includes a motor 201 whose pin is connected to one side of a base 3. The output end of the motor 201 is fixedly connected to a sleeve shaft 202. The other end of the sleeve shaft 202 is fixedly connected to a threaded rod 203. A rotating shaft 204 is rotatably connected to the inner wall of the threaded rod 203. The outer walls of the sleeve shaft 202 and the rotating shaft 204 are rotatably connected to the base 3. The other end of the rotating shaft 204 is fixedly connected to a handle 8 inside. When in use, first select according to the specifications of the high-durability concrete pipe piles. The driving mechanism 2 can be used in cooperation with other mechanisms for adjustment. The driving mechanism 2 mainly provides a driving force to assist the normal progress of the adjustment work, and thus can help adjust the thickness of the concrete pipe piles. Specifically, use a lifting device to place the mold on the base 3, and then start the motor 201 on one side of the base 3 to drive the threaded rod 203 at the other end of the sleeve shaft 202 to rotate. When the threaded rod 203 rotates, the whole device has a driving force. There is a convex block on the outer walls of both the threaded rod 203 and the rotating shaft 204 to limit other components, so that the adjustment of the whole device can proceed smoothly.

[0028] As Figure 4 and Figure 7As shown, a base 3 is rotatably connected to the outer wall of the driving mechanism 2, a splicing board 4 is movably connected to one side of the main body 1, a feeding pipe 5 is fixedly connected to the surface of the splicing board 4, and an adjusting mechanism 6 is installed on the outer wall of the driving mechanism 2. The adjusting mechanism 6 includes a support ring 601 rotatably connected to the outer wall of the threaded rod 203. A plurality of first connecting rods 602 are rotatably connected to the outer wall of the support ring 601. Two fixing rings 603 are fixedly connected to the outer wall of the rotating shaft 204. A plurality of second connecting rods 604 are rotatably connected to the outer walls of the two fixing rings 603. The other ends of the plurality of first connecting rods 602 are all rotatably connected to a first support plate 605. A plurality of springs 606 are fixedly connected to the inner sides of both sides of the plurality of first support plates 605. The other ends of the plurality of springs 606 are all fixedly connected to a telescopic plate 607. The other ends of the plurality of second connecting rods 604 are respectively rotatably connected to the corresponding first support plates 605. As the driving mechanism 2 rotates, it will drive the adjusting mechanism 6 to start operating. As the adjustment work progresses, the diameter will expand outwards, and it can ensure that there will be no leakage after high-durability concrete is injected and the sealing state with other mechanisms. At the same time, after the concrete injection is completed, it can also rotate to help the concrete be shaken evenly, thereby enabling the surface of the concrete pipe pile to be smooth. Specifically, as the threaded rod 203 rotates, it will drive the support ring 601 on the outer wall of the threaded rod 203 to move, thereby driving a plurality of first connecting rods 602 to jack upwards until the corresponding first support plates 605 are jacked upwards by the plurality of first connecting rods 602. As the plurality of second connecting rods 604 and the first connecting rods 602 stand upright, they will expand outwards. Subsequently, the plurality of springs 606 will expand outwards to push out the telescopic plate 607. At this time, it will drive the first support plate 605 to move to one side. Subsequently, the main body 1 can be combined according to the adjusted position.

[0029] As Figure 5 and Figure 7As shown, two supporting mechanisms 7 are installed on the outer wall of the driving mechanism 2, and a handle 8 is fixedly connected to the other end of the driving mechanism 2. The supporting mechanism 7 includes a fixed plate 701 movably connected to the outer wall of the rotating shaft 204, and a circular plate 702 is rotatably connected inside the fixed plate 701. A plurality of arc grooves 703 are provided inside the circular plate 702, and support columns 704 are slidably connected inside the plurality of arc grooves 703. The other ends of the plurality of support columns 704 are fixedly connected to a second supporting plate 705, and connecting grooves 706 are provided on both sides of the plurality of second supporting plates 705. One of the supporting mechanisms 7 is movably connected to the driving mechanism 2, and the plurality of connecting grooves 706 are respectively squeezed and connected with the corresponding telescopic plates 607. When the adjusting mechanism 6 is opened, the supporting mechanism 7 can be combined and sealed, thereby forming a circular ring. Specifically, the circular plate 702 is driven to rotate under the limitation of the protrusion on the threaded rod 203 and the circular plate 702. As it rotates, It will drive multiple support columns 704 to slide on the corresponding arc grooves 703, and then multiple support columns 704 will be pushed up until the corresponding second support plates 705 are stretched to the required thickness of the required concrete pipe. With the movement of the adjustment mechanism 6, the position of the rotating shaft 204 can be adjusted at this time so that the second support plate 705 can be aligned with the first support plate 605. The second support plate 705 and the first support plate 605 on one side and the plate on the other side of the main body 1 have a limited connection relationship. When the circular plate 702 is rotated and adjusted, since the limited fixing plate 701 does not rotate, the main body 1 shell is then taken out and the puzzle plates 4 are spliced, and then the material is injected. The air intake can be quickly detached by the detachment of the main body 1. During the overall rotation process, the main body 1 and the support mechanism 7 always move with the rotation of the rotating shaft 204. It will be limited during the movement and will not rotate with the rotation of the threaded rod 203.

[0030] A method for using a mold made of a high-durability concrete pipe comprises the following specific steps:

[0031] Step 1: Use a lifting device to place the mold on the base 3, then start the motor 201 on one side of the base 3 to drive the threaded rod 203 at the other end of the sleeve shaft 202 to rotate, and then drive the circular plate 702 to rotate under the limit of the protrusion on the threaded rod 203 and the circular plate 702. As the rotation, it will drive multiple support columns 704 to slide on the corresponding arc grooves 703, and then the multiple support columns 704 will be pushed up until the corresponding second support plate 705 is opened to the required thickness of the concrete pipe, and this operation is completed;

[0032] Step 2: As the threaded rod 203 rotates, it will drive the support ring 601 on the outer wall of the threaded rod 203 to move, and then drive multiple first connecting rods 602 to jack up until the multiple first connecting rods 602 jack up the corresponding first support plate 605. As the second support plate 705 moves, at this time, the distance between the first support plate 605 and the second support plate 705 will open. Subsequently, multiple springs 606 will expand outwards to push out the telescopic plate 607 to contact the connecting grooves 706 on both sides of the multiple second support plates 705.

[0033] Step 3: When the mold adjustment is completed, at this time, the two main bodies 1 are combined and installed on the base 3 according to the opened position. Subsequently, highly durable concrete is put in from the feeding pipe 5, and the concrete will flow into the space between the main body 1, the first support plate 605 and the second support plate 705. When the concrete is filled, manually hold the handle 8 and rotate it. After it solidifies, use a lifting device to separate it. Thus, the production of highly durable concrete pipes is completed.

[0034] The above is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
