DETAILED DESCRIPTION

[0031] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0032] See also Figure 1-5 A large-scale component concrete casting mold includes an assembly base 1, an assembly bracket 2, a lifting frame plate 3, and a traveling base 4. The assembly bracket 2 is fixedly installed on the assembly base 1, the lifting frame plate 3 is assembled on the assembly bracket 2 and moves up and down in the vertical direction, and the traveling base 4 is assembled on the assembly base 1 and arranged below the lifting frame plate 3.

[0033] It also includes a top mold 51, a bottom mold 52, two groups of oppositely arranged side molds 53, and two groups of oppositely arranged end molds 54. The top mold 51 is fixedly assembled on the lifting frame plate 3 in a detachable manner, the end mold 54 is slidably assembled on the lifting bracket and runs along the length direction of the lifting frame plate 3, the bottom mold 52 is fixedly installed on the traveling base 4 and arranged below the top mold 51, and the side molds 53 are assembled on the assembly base 1 in a relatively traveling manner and are arranged on both sides of the bottom mold 52.

[0034] The inner cavity formed by the top form 51 , the bottom form 52 , the side form 53 and the end form 54 is used to cast the large concrete component 6 .

[0035] The assembly base 1 is formed as a whole by pouring reinforced concrete, and the assembly bracket 2 is made by assembling and welding steel beams and steel plates, and is pre-buried in the assembly base 1 to form a unified whole with the assembly base 1. The lifting frame plate 3 is assembled on the assembly bracket 2 in a vertical lifting manner, which can drive the top mold 51 and the end mold 54 to rise and fall synchronously. The two groups of end molds 54 slide along the length direction of the lifting bracket, which can facilitate the control of the assembly and disassembly of the end mold 54 with the top mold 51, the side mold 53, and the bottom mold 52.

[0036] Taking the production of the beam structure used to support the bridge box structure during bridge construction as an example, the large-scale component concrete casting and forming mold provided in this application is explained.

[0037] The side form 53 moves laterally and can be controlled to move closer to or further away from the center line of the assembly base 1. When the side form 53 approaches the center line of the assembly base 1, it can be assembled with the bottom form 52, top form 51, and end form 54 below to form a complete casting chamber, ensuring stable casting of large concrete components 6.

[0038] The bottom form 52 can move linearly along the length direction on the assembly base 1. After the large concrete component 6 is cast and formed and the top form 51, side form 53 and end form 54 are removed, the traveling base 4 and the bottom form 52 are controlled to move along the length direction, thereby driving the cast large concrete component 6 to be taken out from the assembly base 1 in the length direction, making it convenient for the staff to remove the large concrete component 6 after demolding from the bottom form 52 and hoist it for transportation, so as to facilitate the casting of the next large concrete component 6.

[0039] During the mold closing stage, the following operating procedures are followed: first, the traveling base 4 is controlled to drive the bottom mold 52 to move to the bottom of the top mold 51; then the two sets of side molds 53 are controlled to move closer to the center line of the assembly base 1 to realize the matching assembly of the side molds 53 and the bottom mold 52; then the upper frame is controlled to drive the top mold 51 and the end mold 54 downward to realize the matching assembly of the top mold 51 and the top of the side mold 53; finally, the two sets of end molds 54 are controlled to move relative to each other to realize the assembly of the end mold 54 with the corresponding end of the top mold 51, the bottom mold 52 and the side mold 53 to form a complete mold closing posture.

[0040] After the mold closing operation is completed, the steel bars 61 are tied and positioned in the formed casting cavity, and then concrete slurry is poured into the casting cavity. After cooling and shaping, each mold is demolded. The demolding process is the opposite of the mold closing operation.

[0041] After the formwork is removed, the cast large concrete component 6, i.e., the beam structure, is located above the bottom form 52. The traveling base 4 is controlled to move outward to remove the beam structure and the bottom form 52, allowing the beam structure to be dismantled and hoisted for transport. Simultaneously, another set of traveling bases 4 and their upper bottom form 52 move below the top form 51 and close the molds to prepare for the next beam structure.

[0042] In order to ensure that the assembly base and the bottom mold 52 can move stably along the length direction on the assembly base 1, the following technical solution is provided.

[0043] A guide trough 11 is provided on the assembly base 1 along its center line, and a guide rail A is fixed in the guide trough 11. The traveling base 4 is arranged in the guide trough 11, and the bottom of the traveling base 4 is equipped with a support wheel A41 that is matched with the guide rail A. Winches 71 are installed at both ends of the guide trough 11, and the steel rope 711 released by the winch 71 is fixedly connected to the end face of the traveling base 4.

[0044] The setting of the guide trough 11 can ensure that the traveling base 4 is stably assembled therein, and cooperates with the combination of the guide rail A and the support wheel A41 to ensure that the traveling base 4 and the bottom mold 52 fixed thereon can move stably along the length direction of the guide trough 11. In the process of the winch 71 controlling the recovery of the corresponding steel rope 711, the traveling base 4 can be pulled to move stably along the winch 71 on this side. At the same time, the winch 71 at the other end controls the synchronous release of the steel rope 711 thereon.

[0045] In order to ensure the supporting effect of the beam structure on the upper bridge box, the side walls of the beam structure are usually set to a non-flat plane. Therefore, during the demolding process, in order to avoid spatial movement interference between the outward-moving side mold 53 and the cast beam structure, and to ensure effective demolding and closing operations of the side mold 53, the following technical solutions are provided.

[0046] The assembly base 1 is provided with guide bevels 12 arranged on both sides of the guide trough 11, and connecting bevels 42 are provided on both sides of the traveling base 4. The connecting bevels 42 are connected to the bottom mold 52 and the guide bevel 12. A plurality of groups of evenly arranged guide rails B121 are fixed in the guide bevel 12, and a connecting seat 531 is fixed to the outer wall of the side mold 53. The bottom of the connecting seat 531 is equipped with a support wheel B532 that is matched with the guide rail B121. The guide bevel 12 is also equipped with a plurality of groups of evenly arranged hydraulic telescopic cylinders A72, and the two ends of the hydraulic telescopic cylinder A72 are respectively hinged to the assembly base 1 and the connecting seat 531.

[0047] The provision of the guide chute 12 and its upper guide rail B121 ensures that the side forms 53 and the connecting base 531 travel in an oblique direction. During the formwork removal process, the two sets of side forms 53 can be moved downward and outward at an angle, effectively preventing spatial motion interference between the side forms 53 and the large concrete member 6. The provision of the connecting chute 42 ensures that the side forms 53 do not interfere with the traveling base 4 when approaching and mating with the bottom form 52.

[0048] By controlling the synchronous contraction movement of each group of hydraulic telescopic cylinders A72, the corresponding side molds 53 can be controlled to be stably retracted and extended along the guide inclined groove 12, so as to control the mold closing and demolding operations of the side molds 53.

[0049] In order to ensure that the lifting frame plate 3 is stably lifted and lowered in the vertical direction and to ensure that the top mold 51 and the lifting frame plate 3 are matched and combined in a detachable manner, the following technical solutions are provided.

[0050] Multiple groups of hydraulic telescopic cylinders B73 arranged in the vertical direction are fixedly installed on the top of the assembly bracket 2, and the movable ends of the hydraulic telescopic cylinders B73 are fixedly connected to the lifting frame plate 3; multiple groups of positioning seats 31 are fixedly connected to the lower surface of the lifting frame plate 3, and the upper surface of the top mold 51 is fixedly connected to the positioning sleeve 511 that is nested and matched with the positioning seat 31. The side walls of the positioning seat 31 and the positioning sleeve 511 are provided with positioning pin holes that maintain horizontal relative position.

[0051] By synchronously controlling the telescopic posture of each set of hydraulic telescopic cylinders B73, the lifting frame 3 can be stably raised and lowered in the vertical direction. When assembling the top mold 51 onto the lifting frame 3, the positioning base 31 is controlled to nest and insert with the corresponding positioning sleeve 511 to ensure that the positioning pin holes thereon are horizontally aligned. By inserting the positioning pin shafts into the positioning pin holes, the top mold 51 can be quickly assembled onto the lifting frame 3.

[0052] When tying the steel bars 61 in the casting chamber formed after the mold is closed, in order to facilitate the effective fixation of the steel bars 61 and ensure that the steel bars 61 are distributed in the casting chamber according to the design requirements, longitudinal sockets 512 and transverse sockets 541 are respectively opened on the top mold 51 and the end mold 54 to ensure that the longitudinally distributed steel bars 61 can be inserted and positioned in the longitudinal sockets 512, and to ensure that the transversely distributed steel bars 61 can be inserted and positioned in the transverse sockets 541.

[0053] A pouring port 513 is also provided on the top mold 51, which allows the feeding pipe to transport concrete slurry from the pouring port 513 to the pouring chamber. At the same time, a clearance opening 32 is provided at a corresponding position on the lifting frame plate 3 to ensure that the feeding pipe can connect with the pouring port 513 through the lifting frame plate 3.

[0054] In order to ensure that the end mold 54 can be stably assembled on the lifting frame plate 3 in a relatively sliding manner and to ensure that the end mold 54 can stably slide along the length direction of the lifting frame plate 3, the following technical solution is provided.

[0055] Guide grooves 33 are provided at both ends of the lifting frame plate 3, and a guide seat 542 is fixedly connected to the top of the end mold 54 to maintain a sliding combination with the guide groove 33. A horizontally arranged hydraulic telescopic cylinder C74 is fixedly installed on the lifting frame plate 3, and the movable end of the hydraulic telescopic cylinder C74 is fixedly connected to the guide seat 542.

[0056] The combination of the guide groove 33 and the guide seat 542 can ensure that the end mold 54 slides stably along the length direction of the lifting frame plate 3. By controlling the telescopic posture of the hydraulic telescopic cylinder C74, the end mold 54 can be driven to run stably, thereby realizing the demolding and closing operations of the end mold 54.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
