Description

Technical Field

[0001] The present invention relates to the technical field of precast component pouring, and more specifically, it relates to a pouring and forming device for concrete precast components and its operation method. Background Art

[0002] In the field of precast component production, the forming block is a key mold component, and its replacement and adjustment directly affect production efficiency and product quality. In traditional processes, precast components of different specifications and shapes need to be poured and formed using corresponding forming blocks. This process requirement makes it necessary to frequently replace the molds on the production line. However, since forming blocks are generally made of metal materials, they have a large volume and weight, and in addition, they need to withstand pouring pressure during the production process. Therefore, multiple bolts are often used for fixed connection during design to ensure the stability and safety of the forming process.

[0003] This traditional bolt connection method exposes serious problems such as difficult operation and low efficiency in practical applications. Each time the forming block is replaced, the operator needs to disassemble and install a large number of bolts in sequence, which not only consumes a lot of manpower and time, but also increases the labor intensity of the workers. Especially during continuous production, frequent mold replacement operations seriously affect production efficiency. At the same time, the repeated disassembly and assembly of bolts are also likely to cause problems such as thread wear and deformation, affecting the reliability of the connection and the service life of the mold. Summary of the Invention

[0004] (I) Technical Problems to be Solved In view of the problems existing in the prior art, the present invention provides a pouring and forming device for concrete precast components and its operation method to solve the technical problems mentioned in the background art.

[0005] (II) Technical Solutions To achieve the above object, the present invention provides the following technical solutions: A pouring and forming device for concrete precast components includes a fixedly installed frame and a lifting table; it further includes an installation mechanism. The installation mechanism includes a forming block attached to the lower end face of the lifting table. An inner sleeve is installed on the lifting table. A follower disk is installed on the forming block. An insertion sleeve is coaxially installed on the follower disk. The insertion sleeve is slidably connected to the inner sleeve. A plurality of sliding grooves are formed on the side wall of the inner sleeve. Each sliding groove is slidably connected with a side block. A plurality of one-way blocks are equidistantly installed on the side block. A spring is installed inside the side block. A plurality of transverse holes are formed on the side wall of the insertion sleeve. Each transverse hole is slidably connected with a transverse rod. The transverse rod is stuck on the one-way block. The spring abuts against the transverse rod; it further includes a pouring mechanism. The pouring mechanism includes a feeding hopper installed on the frame.

[0006] Preferably, the installation mechanism further includes push springs installed on the plurality of side blocks, a fixing rod is installed on the plurality of push springs, and the fixing rod is fixedly installed in the sliding groove. Through the cooperation of the push springs and the fixing rod.

[0007] Preferably, an intermediate rod is slidably installed in the insertion sleeve. A plurality of spaced grooves are equidistantly formed on the intermediate rod. Two ejector rods are installed on the frame, and the ejector rods and the intermediate rod are coaxially arranged. A plurality of expansion springs are equidistantly installed in the follower disc. A plurality of annular grooves are formed at the lower end of the intermediate rod. And the plurality of expansion springs abut against the annular grooves. This design realizes motion control. The coaxial cooperation between the intermediate rod and the ejector rod ensures the accuracy of vertical motion. The arrangement of the spaced grooves provides a reliable storage space for the cross bar.

[0008] Preferably, a plurality of bottom rods are equidistantly installed on the lower end surface of the inner sleeve. A plurality of bottom holes are installed on the lower end surface of the follower disc. The bottom rods are inserted into the bottom holes. This design can not only ensure the accurate centering during the installation of the forming block, but also prevent deflection during the installation process.

[0009] Preferably, the pouring mechanism includes a plurality of conveying rollers installed on the frame. Two side plates are symmetrically installed inside the frame. A forming box is arranged on the conveying rollers. Both sides of the forming box are attached to the side plates. The conveying rollers provide horizontal conveying ability, and the symmetrically arranged side plates provide reliable lateral support and guidance for the forming box, ensuring the stability of the forming box during the conveying process.

[0010] Preferably, two vertical hydraulic cylinders are installed on the frame. The extending end of the vertical hydraulic cylinder is connected to the lifting platform. A plurality of guide rods are installed on both sides of the frame. The lifting platform is slidably connected to the plurality of guide rods. Through the coordinated work of the hydraulic cylinder and the guide rods, the control of the lifting platform is realized.

[0011] Preferably, a push rod is installed on the side wall of each forming box, and the push rod abuts against the adjacent forming box. This push rod connection design maintains an appropriate distance between adjacent forming boxes.

[0012] Preferably, a baffle is rotatably installed at the lower end of the feeding hopper. A feeding hydraulic cylinder is rotatably installed on the frame. The extending end of the feeding hydraulic cylinder is connected to the baffle.

[0013] The present invention provides a method for pouring and forming concrete precast components, including the following steps: When the forming block needs to be replaced, the hydraulic cylinder drives the lifting platform to move upward, so that the middle rod supports the top rod and continues to move upward. At this time, the middle rod moves downward to align the spacing groove with the position of the transverse rod. Although the transverse rod is still in a clamping state with the one-way block at this time, when the lifting platform moves downward to make the forming block fall on the conveying roller, the friction between the transverse rod and the one-way block disappears because the gravity of the forming block is borne by the conveying roller. Under the action of the push spring, the transverse rod can slide smoothly into the spacing groove, thereby realizing the rapid removal of the forming block. When installing a new forming block, first push the middle rod to make the transverse rod press against its side wall to achieve the limit position, then place the new forming block with the follower plate under the lifting platform, and move the lifting platform downward to make the insertion sleeve enter the inner sleeve. At this time, the bottom positioning structure ensures that the transverse rod is aligned with the one-way block. When the transverse rod contacts the one-way block, the side block is pushed to slide and expand in the slide slot, and finally the transverse rod and the one-way block are firmly connected, completing the rapid installation of the forming block. During pouring, the forming box is placed on the conveying roller. Adjacent forming boxes are connected by push rods and fixed on both sides by side plates. When the forming box moves to the bottom of the discharge hopper, the baffle is opened by the hydraulic cylinder to pour concrete. After pouring, the forming box is transported to the bottom of the lifting platform, and the concrete is pressed and formed by pressing the forming blocks. After the concrete is initially solidified, the forming box is transported out of the work station to complete the entire pouring and forming process.

[0014] (III) Beneficial effects Compared with the prior art, the present invention provides a concrete precast component casting and molding device and an operation method thereof, which have the following beneficial effects: The equipment adopts a quick replacement mechanism for forming blocks. Through the cooperation of the internal sleeve and the insertion sleeve, combined with the guiding function of the follower plate, the rapid installation and removal of the forming blocks are realized. This design completely abandons the traditional bolt connection method. The operator only needs to complete the replacement through a simple lifting action, which greatly reduces the replacement time and improves production efficiency. Through the cooperation of the transverse rod and the one-way block, combined with the preload design of the spring, a reliable self-locking system is formed. When the forming block is subjected to the pouring pressure, the locking mechanism will lock the force to ensure the stability of the connection. At the same time, the unlocking process is very simple and can be completed automatically through the lifting action, which not only ensures safety but also improves the convenience of operation.

[0015] The release of concrete is controlled by the coordination of the discharge hopper, baffle and hydraulic cylinder. The conveying roller system ensures the continuous delivery of the forming box. The limiting function of the push rod makes the entire pouring process smoother and more stable. All operations of the equipment are conveniently designed. Whether it is the replacement of the forming blocks or the pouring of concrete, only simple control actions are required to complete it. This design not only reduces the labor intensity of the operators, but also reduces the possibility of operating errors and improves production safety. Brief Description of the Drawings

[0021] Please refer to Figures 1 to 10 , a concrete precast member casting and forming device, including a fixedly installed frame 11 and a lifting table 12; further including an installation mechanism, the installation mechanism includes a forming block 21 attached to the lower end face of the lifting table 12, an inner sleeve 22 is installed on the lifting table 12, a follower disk 23 is installed on the forming block 21, an insertion sleeve 24 is coaxially installed on the follower disk 23, the insertion sleeve 24 is slidably connected in the inner sleeve 22, a plurality of sliding grooves 25 are opened on the side wall of the inner sleeve 22, each sliding groove 25 is respectively slidably connected with a side block 26, a plurality of one-way blocks 27 are equidistantly installed on the side block 26, a spring 28 is installed in the side block 26, a plurality of transverse holes 29 are opened on the side wall of the insertion sleeve 24, each transverse hole 29 is respectively slidably connected with a transverse rod 210, the transverse rod 210 is stuck on the one-way block 27, the spring 28 abuts against the transverse rod 210, the installation mechanism further includes a push spring 211 installed on a plurality of side blocks 26, a fixing rod 212 is installed on the plurality of push springs 211, the fixing rod 212 is fixedly installed in the sliding groove 25, the installation mechanism further includes a push spring 211 installed on a plurality of side blocks 26, a fixing rod 212 is installed on the plurality of push springs 211, the fixing rod 212 is fixedly installed in the sliding groove 25, an intermediate rod 213 is slidably installed in the insertion sleeve 24, a plurality of spaced grooves 214 are equidistantly opened on the intermediate rod 213, two ejector rods 215 are installed on the frame 11, and the ejector rods 215 and the intermediate rod 213 are coaxially arranged, a plurality of expansion springs 216 are equidistantly installed in the follower disk 23, and a plurality of annular grooves 217 are opened at the lower end of the intermediate rod 213, and the plurality of expansion springs 216 abut against the annular grooves 217, a plurality of bottom rods 218 are equidistantly installed on the lower end face of the inner sleeve 22, a plurality of bottom holes 219 are installed on the lower end face of the follower disk 23, and the bottom rods 218 are inserted into the bottom holes 219.

[0022] When the corresponding forming block 21 needs to be replaced, first, the existing forming block 21 needs to be removed. The lifting table 12 is driven upward by the vertical hydraulic cylinder 35, so the forming block 21 will be driven upward accordingly. Then, the upper end of the middle rod 213 will abut against the ejector rod 215. At this time, continuing to move upward will push the middle rod 213 downward. When the upper end of the middle rod 213 fits against the insertion sleeve 24, the multiple spacing grooves 214 will also move to the position of the cross bar 210, and the lower end expansion spring 216 will also be stuck in the annular groove 217 at the corresponding position, generating a corresponding fixing force. At this time, since the cross bar 210 is still stuck on the one-way block 27 and the forming block 21 is limited by the connection of the multiple cross bars 210 and the one-way block 27, there is a large frictional force between the two. Although the spring 28 abuts against the cross bar 210, it cannot push the cross bar 210. And the end of the cross bar 210 close to the middle rod 213 is in a slidable state. At this time, the lifting table 12 and the forming block 21 are moved downward until the forming block 21 is placed on the conveying roller 32. At this time, the conveying roller 32 bears the gravity of the forming block 21. Therefore, there is no force between the one-way block 27 and the cross bar 210. Thus, the push spring 211 can push the cross bar 210 to slide inward, making it move into the space of the spacing groove 214. Then, the connection between the cross bar 210 and the one-way block 27 is released. At this time, the connection between the forming block 21 and the lifting table 12 is completely released. Therefore, the existing forming block 21 can be moved away to prepare for the installation of a new forming block 21. Simply put, when it is necessary to release the connection between the forming block 21 and the lifting table 12, first move upward to move the spacing groove 214 of the middle rod 213 to the position of the cross bar 210, and then move downward so that the lifting table 12 no longer bears the gravity of the forming block 21. At this time, the connection can be released. The whole operation is very simple and convenient.

[0023] After the forming block 21 is disassembled, a new installation is required. Since the follower disc 23 is fixedly installed on the forming block 21, first push the intermediate rod 213 so that multiple transverse rods 210 abut against the side wall of the intermediate rod 213. At this time, the limit of the transverse rods 210 is ensured. Then place the new forming block 21 at the lower end of the lifting table 12, and then align the insertion sleeve 24 with the position of the inner sleeve 22. Move the lifting table 12 downward so that the insertion sleeve 24 is inserted into the inner sleeve 22, and the connection between the bottom rod 218 and the bottom hole 219 ensures the alignment of the transverse rods 210 and the one-way block 27. When the transverse rod 210 abuts against the one-way block 27, it will push the side block 26 to slide along the chute 25, causing multiple side blocks 26 to expand outwards. Then, the transverse rod 210 is stuck on the one-way block 27, and the follower disc 23 fits on the inner sleeve 22, and the spring 28 abuts against the transverse rod 210. Since the transverse rod 210 abuts against the side wall of the intermediate rod 213, the transverse rod 210 will not move, and the transverse rod 210 will be stably stuck on the one-way block 27, thereby ensuring the stability between the forming block 21 and the lifting table 12. Simply put, after aligning the follower disc 23 and the inner sleeve 22, directly move them downward so that the insertion sleeve 24 is inserted into the inner sleeve 22 to complete the installation process.

[0024] The pouring mechanism includes a feeding hopper 31 installed on the frame 11. The pouring mechanism includes multiple conveying rollers 32 installed on the frame 11. Two side plates 33 are symmetrically installed inside the frame 11. A forming box 34 is arranged on the conveying roller 32. Both sides of the forming box 34 are attached to the side plates 33. Two vertical hydraulic cylinders 35 are installed on the frame 11. The extending end of the vertical hydraulic cylinder 35 is connected to the lifting table 12. Multiple guide rods 36 are installed on both sides of the frame 11. The lifting table 12 is slidably connected to the multiple guide rods 36. A push rod 37 is installed on the side wall of each forming box 34. The push rod 37 abuts against the adjacent forming box 34. A baffle 38 is rotatably installed at the lower end of the feeding hopper 31. A feeding hydraulic cylinder 39 is rotatably installed on the frame 11. The extending end of the feeding hydraulic cylinder 39 is connected to the baffle 38.

[0025] When precast components need to be poured, first place the forming boxes 34 on the conveying rollers 32 respectively, and the adjacent forming boxes 34 are connected by abutting through the push rods 37. The limiting process is ensured by attaching both side plates 33 to the side walls of the forming boxes 34. When the forming box 34 moves to the lower end of the feeding hopper 31, the baffle 38 is driven by the feeding hydraulic cylinder 39 to rotate to release the seal, and the concrete flows into the forming box 34. After completion, the forming box 34 is conveyed to the lower end of the lifting table 12, and then the forming block 21 is moved downward so that the forming block 21 presses on the concrete in the forming box 34. When the concrete is pre-solidified, it is conveyed downward, thus completing the forming process.
