Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and particularly relates to a multi-wheel movable beam-making pedestal. Background Art

[0002] During the construction of standard bridge superstructures, prefabrication is typically used to ensure quality and efficiency. Once prefabrication is complete, the relevant structural components are transported to the construction site and installed and secured according to design requirements.

[0003] Traditional prefabricated beams rely too much on fixed prefabricated pedestals, cranes, gantry cranes and manual labor during production, resulting in low production efficiency, lack of effective linkage between various links, and inability to form efficient and fast assembly line operations. Of course, movable quality pedestals are also disclosed in the prior art, such as CN216099532U, which discloses a movable pedestal for prefabricated T-beams, including a bottom mold template, a mobile vehicle body installed at the bottom of the bottom mold template, and a number of support plates equidistantly provided at the bottom of the mobile vehicle body along its length. Sliding mechanisms are installed at the bottom of both sides of the support plates, and a driving mechanism is installed on the sliding mechanism; a track is installed at the bottom of the sliding mechanism. The movable pedestal disclosed in this patent adopts hydraulic templates, mobile pedestals and other equipment, which reduces the labor intensity of template assembly and hoisting operations, improves the turnover rate of prefabricated pedestals, reduces the number of prefabricated pedestals, reduces the construction site area, saves land resources, is green and environmentally friendly, and has high social value and market promotion value.

[0004] It is undeniable that the movable pedestal for prefabricated T-beams disclosed in this patent can indeed achieve the above-mentioned effects, but it still has certain shortcomings: when lifting and disassembling the prefabricated beam bottom support, the removable base plate needs to be removed. However, during the operation, the prefabricated beam is pressed against the removable base plate, which is difficult to remove directly, making it inconvenient to lift and disassemble the prefabricated beam bottom support. In addition, when using the movable pedestal disclosed in this patent, the mobile body needs to be lifted onto the track in order to produce the prefabricated beam, but the mobile body is not equipped with any lifting-related structure, which makes it inconvenient to lift the mobile body.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without making any creative efforts are within the scope of protection of this utility model.

[0042] Example

[0043] See attached Figure 1-9 , a multi-wheel mobile beam-making pedestal, comprising:

[0044] The platform foundation 1 has two rails 11 extending along its length fixed thereon at intervals; the platform foundation 1 is provided with a plurality of cable interfaces 12 at intervals between the two rails 11;

[0045] A mobile body 2 is mounted on the platform foundation 1 and moves along the length of the platform foundation 1; a mounting seat 21 is fixed to the front end of the mobile body 2, and a winding drum 22 is mounted on the mounting seat 21 and rotated with the mounting seat 21; a ladder 23 is fixed to the rear end of the mobile body 2; in addition, a plurality of hanging columns 24 perpendicular to the mobile body 2 are fixed at even intervals on both sides of the mobile body 2, and a limit plate 241 is fixed to the outer end of the hanging column 24; in order to improve the stability and load capacity of the hanging column 24, a reinforcing plate 242 is welded to the circumference of the inner end of the hanging column 24;

[0046] Multiple running mechanisms 3 are fixed at intervals at the bottom of the mobile body 2; specifically, the running mechanism 3 includes wheel boxes 31 symmetrically fixed to both sides of the mobile body 2 and a chassis 32 fixed between the two wheel boxes 31; wherein, a wheel axle 33 is fixed laterally in the wheel box 31, and a running wheel 34 is mounted on the wheel axle 33 for rotational cooperation with the running wheel 34 and for guiding cooperation with the track 11; a driven gear 35 is also sleeved on the wheel axle 33, and the driven gear 35 is fixed to the inner side of the running wheel 34; two reduction motors 36 corresponding to the driven gears 35 are symmetrically arranged in the chassis 32, and the output shaft of the reduction motor 36 extends into the wheel box 31 and is fixed with a driving gear 37 that meshes with the driven gear 35; it should be supplemented here that the bottom of the running wheel 34 extends from the bottom of the wheel box 31 to facilitate cooperation with the track 11;

[0047] A main pedestal bottom mold 4 extends along the length of the mobile body 2 and is fixed to the middle position of the top of the mobile body 2. An auxiliary pedestal bottom mold 5 is fixed to each end of the main pedestal bottom mold 4. Specifically, the main pedestal bottom mold 4 includes a bottom mold distribution beam 41 fixed at intervals to the top of the mobile body 2, a plurality of bottom mold longitudinal beams 42 fixed along the length of the mobile body 2 and perpendicular to the top of the bottom mold distribution beam 41, a bottom mold steel plate 43 fixed to the top of the bottom mold longitudinal beam 42, and rubber stop strips 44 fixed to the bottom mold longitudinal beams 42 on both sides of the bottom mold steel plate 43. In this embodiment, the main pedestal bottom mold 4 and the auxiliary pedestal bottom mold 5 have the same structure.

[0048] A lifting mechanism 6 is provided between the main pedestal bottom mold 4 and the auxiliary pedestal bottom mold 5. Specifically, the lifting mechanism 6 includes a fixing plate 61 symmetrically fixed to the bottom of the main pedestal bottom mold 4 and the bottom of the auxiliary pedestal bottom mold 5, and a plurality of adjusting bolts 62 spaced apart and threadedly engaged with the fixing plate 61. The adjusting bolts 62 extend from the bottom of the fixing plate 61 through the fixing plate 61 and extend from the top of the fixing plate 61.

[0049] The support plate 7 is disposed between the main pedestal bottom mold 4 and the auxiliary pedestal bottom mold 5 and is located at the top of the lifting mechanism 6. Specifically, the support plate 7 abuts against the top of the adjusting bolt 62. It should be noted that a nut threadedly engaged with the adjusting bolt 62 is fixed to the top of the fixing plate 61. When the top of the support plate 7 is flush with the top of the main pedestal bottom mold 4 and the top of the auxiliary pedestal bottom mold 5, there is a certain distance between the nut and the support plate 7.

[0050] It should be noted that in this embodiment, the cable interface 12 is provided with a power supply circuit connected to an external power source. When in use, the reduction motor 36 in this embodiment is connected to the power supply circuit in the cable interface 12 via a cable. Furthermore, when not in use, the cable interface 12 is sealed with a lightweight cover to prevent water ingress and dust accumulation. In this embodiment, a cable winding reel 22 is also provided to accommodate the cable connecting the reduction motor 36 and the power supply circuit.

[0051] During use, an external machine uses the lifting columns 24 to lift the mobile body 2, together with the traveling mechanism 3, the main pedestal bottom mold 4, and the auxiliary pedestal bottom mold 5, onto the base 1, and aligns the traveling wheels 34 with the tracks 11 on the base 1. It can be seen that the provision of the lifting columns 24 facilitates the lifting of the entire device. In addition, the provision of the limit plate 241 at the outer end of the lifting column 24 prevents the lifting rope from being detached, ensuring the safety and stability of the lifting process; and the reinforcement plate 242 on the inner end circumference of the lifting column 24 improves the stability and load capacity of the fixing of the lifting column 24.

[0052] When manufacturing precast beams, the mobile body 2 is moved to different process areas with the help of the traveling mechanism 3, such as casting, steaming, and tensioning and grouting. Specifically, the reduction motor 36 is started, and the reduction motor 36 drives the driving gear 37 to rotate, and the driving gear 37 drives the driven gear 35 to rotate, and the driven gear 35 drives the traveling wheel 34 to rotate synchronously, and the traveling wheel 34 rolls along the track 11. In this way, the reduction motors 36 of multiple traveling mechanisms 3 are turned on at the same time, which can drive the mobile body 2 to move on the track 11. When the mobile body 2 moves to the appropriate process area, the reduction motor 36 can be turned off; after the construction of this process is completed, the reduction motor 36 is started again to move the mobile body 2 to the next process area.

[0053] In addition, during the process of making the precast beam, the top of the support plate 7 is flush with the top of the main pedestal bottom mold 4 on both sides and the top of the auxiliary pedestal bottom mold 5; when the precast beam is subsequently hoisted and disassembled, the adjusting bolt 62 is loosened, and the top of the adjusting bolt 62 moves downward, and the support plate 7 moves downward as the top of the adjusting bolt 62 moves downward. After the support plate 7 is separated from the precast beam, the support plate 7 is removed and the bottom lifting and disassembly can be carried out. The operation is convenient and convenient for the bottom lifting and disassembly of the precast beam. The design meets the actual production needs. Similarly, when the adjusting bolt 62 is tightened, the top of the adjusting bolt 62 moves upward, and the top of the support plate 7 can be adjusted to be flush with the top of the main pedestal bottom mold 4 on both sides and the top of the auxiliary pedestal bottom mold 5.
