Description

Technical Field

[0001] The invention relates to a prefabricated box beam bottom mold hydraulic trolley, belonging to the technical field of engineering equipment. Background Art

[0002] The construction of the bottom formwork of prefabricated box girders is an important part of bridge construction. During construction, the bottom formwork must be accurately processed according to the design drawings to ensure that it meets the size and stiffness requirements. The bottom formwork often adopts a channel steel frame structure, with steel plates laid on it and welded as a whole. After the formwork is processed, it needs to be installed on the pedestal, and the anti-camber and compression amount are preset. During the installation process, the flatness, verticality and fit of the formwork with the pedestal must be strictly controlled to ensure the geometric size and quality of the prefabricated box girder.

[0003] In the traditional prefabricated box girder bottom formwork construction process, the method of fixing the bottom formwork and lifting and transferring is often adopted. Although it can meet the basic construction needs, there are certain shortcomings in actual operation. For example, the bottom formwork has poor stability during lifting and is prone to displacement and damage. At the same time, the labor intensity is high and the efficiency is low, which is not conducive to improving the construction quality and progress. Summary of the invention

[0004] In view of the defects existing in the above-mentioned prior art, the present invention provides a hydraulic trolley for the bottom mold of a prefabricated box beam, which solves the problems of poor stability, easy deviation and damage, and low efficiency during the transfer of the bottom mold of the prefabricated box beam.

[0005] The purpose of the present invention is achieved through the following technical solutions:

[0006] The present invention provides a hydraulic trolley for a prefabricated box beam bottom mold, including a bottom mold assembly, a hydraulic trolley is arranged below the bottom mold assembly, the hydraulic trolley includes a frame and a plurality of wheel groups, the frame includes two mounting beams, a plurality of connecting beams are equidistantly arranged between the two mounting beams, the connecting beams are connected to the two mounting beams by screws, a plurality of mounting grooves are opened on the bottom side of the mounting beams, the wheel groups are installed on the inner sides of the mounting grooves, and the plurality of wheel groups include a driving wheel, a passive wheel and a wheel group mounting plate.

[0008] Furthermore, two round shafts are installed through the inner side of the wheel axle mounting shell. After the rotating shaft passes through the wheel axle mounting shell, it is connected to the clamping plate through flanges respectively. Steel wheels are installed on the outer sides of the two round shafts. The steel wheels are rotatably connected to the round shafts through bearings.

[0009] Furthermore, a transmission gear is provided between the steel wheel and the inner wall of the axle mounting shell, and the transmission gear is connected to the steel wheel by screws. A hydraulic motor is provided on the outside of the axle mounting shell and is connected by screws. An output gear is provided at the output end of the hydraulic motor after passing through the axle mounting shell, and the output gear is connected to the transmission gear by transmission.

[0010] Furthermore, the passive wheel has a similar structure to the active wheel, and only lacks the transmission gear, the hydraulic motor and the output gear.

[0011] Furthermore, the driving wheel and the driven wheel are both connected to the mounting groove via the wheel assembly mounting plate, and the wheel assembly mounting plate is connected to the wheel axle mounting shell via screws.

[0012] In summary, compared with the prior art, the present invention has the following advantages:

[0013] 1. In the present invention, the installation efficiency and stability of the bottom mold are improved by optimizing the structure of the hydraulic trolley. Specifically, the combination of the bottom mold assembly and the hydraulic trolley enables the bottom mold to be quickly and accurately installed at the predetermined position, greatly improving the construction efficiency.

[0014] 2. In the present invention, a hydraulic motor is provided outside the wheel axle mounting shell and connected to the wheel axle mounting shell by screws. An output gear is provided after the output end of the hydraulic motor passes through the wheel axle mounting shell and is connected to the transmission gear, so that the hydraulic trolley has higher power output and efficiency during the walking process;

[0015] 3. In the present invention, a shock-absorbing rubber is arranged on the driving wheel, which effectively reduces the vibration and noise during operation and improves the quality of the construction environment;

[0016] 4. In the present invention, by providing the driving wheel and the passive wheel, as well as the wheel assembly mounting plate, the precise alignment and adjustment of the wheel assembly is achieved. The structures of the driving wheel and the passive wheel are similar, only the transmission gear, the hydraulic motor and the output gear are missing.

[0026] The technical solution of the present invention is further specifically described below through specific embodiments, but the present invention is not limited to these embodiments.

[0027] Combination Figures 1 to 5 As shown, it includes a bottom mold assembly 1, and a hydraulic trolley 2 is arranged below the bottom mold assembly 1. The hydraulic trolley 2 includes a frame 21 and a plurality of wheel groups 22. The frame 21 includes two mounting beams 211, and a plurality of connecting beams 212 are equidistantly arranged between the two mounting beams 211. The connecting beams 212 are connected to the two mounting beams 211 by screws. A plurality of mounting grooves 213 are opened on the bottom side of the mounting beams 211, and the wheel groups 22 are installed on the inner sides of the mounting grooves 213. The plurality of wheel groups 22 include a driving wheel 221, a driven wheel 222 and a wheel group mounting plate 223. The frame 21 is composed of the mounting beams 211 and the connecting beams 212, which are connected by screws, and the structure is easy to adjust to adapt to box beam bottom molds of different sizes. The plurality of connecting beams 212 ensure the overall stability of the frame 21, and can remain stable even when the box beam bottom mold is loaded with a heavy load.

[0028] Combination Figure 4 and Figure 5 As shown, the driving wheel 221 includes an axle mounting shell 2211, a connecting plate 2212 is provided on the top of the axle mounting shell 2211, a shock-absorbing rubber 2213 is provided on the top of the connecting plate 2212, the connecting plate 2212 is connected to the shock-absorbing rubber 2213 and the mounting beam 211 by screws, and the shock-absorbing rubber 2213 provided on the top of the driving wheel 221 can effectively absorb vibrations during walking and protect the bottom mold assembly 1 from damage.

[0029] Combination Figure 4and Figure 5 As shown, two circular shafts 2214 are installed through the inner side of the axle mounting shell 2211. The rotating shaft passes through the axle mounting shell 2211 and is connected to the clamping plate through flanges respectively. Steel wheels 2215 are installed on the outer sides of the two circular shafts 2214. The steel wheels 2215 and the circular shafts 2214 are rotatably connected through bearings. The two circular shafts 2214 enhance the stability of the driving wheel 221, share the load-bearing, and extend the service life.

[0030] Combination Figure 4 and Figure 5 As shown, a transmission gear 2216 is provided between the steel wheel 2215 and the inner wall of the axle mounting shell 2211, and the transmission gear 2216 is connected to the steel wheel 2215 by screws.
