Description

Technical Field

[0001] The invention relates to the technical field of bridge engineering construction, in particular to a transport trolley for a mobile formwork. Background Art

[0002] Mobile formwork is widely used in the construction of cast-in-place box girders for bridge upper sections due to its high rigidity and strong load-bearing capacity. Currently, the mainstream mobile formwork system for transporting pier-side brackets employs a separate lifting and transporting process. After the superstructure is cast, lifting equipment is used to lift the brackets in sections, transport them as a whole, and install them in sections. These operations require separate equipment for each step. For example, after the formwork is moved forward through a hole, separate lifting equipment is required to lift the main beam and columns of the pier-side brackets. A transport vehicle is then used to transport them to the previous section via a trestle. The lifting equipment then lifts each component sequentially and installs them on the pier cap. The lack of interoperability between the various systems necessitates frequent equipment changes during construction, increasing process transition time and posing the risk of equipment interference. This functionally fragmented design not only restricts the construction pace but also increases construction costs due to the duplication of equipment, creating a technical bottleneck hindering the efficient construction of long-span cast-in-place box girders.

It can flexibly adjust the direction of the hoisted object to meet the hoisting needs in different construction scenarios and improve the flexibility and adaptability of construction.

[0056] The specific structure is as follows:

[0057] like Figure 1 、 Figure 2As shown, the support frame 1 includes a first upper cross beam 101, a first middle cross beam 102, a first lower cross beam 103 and a first side beam 104. The two first side beams 104 are arranged in parallel; the three first upper cross beam 101, the first middle cross beam 102, and the first lower cross beam 103 are orthogonally welded to the first side beam 104 to form a "day" - shaped frame structure, which serves as the main structure of the support frame 1. An inward first connecting ear plate 1011 is provided on the first upper cross beam 101 for connecting the upper guide wheel set 3. A second connecting ear plate 1021 is provided below the middle of the first middle cross beam 102 for connecting the lifting mechanism 8, and first connecting bolts 1022 are provided at both ends of the first middle cross beam 102 for connecting the lower guide wheel set 4. A second connecting bolt 1041 is provided in the middle of the first side beam 104 for connecting the traveling wheel box 5. The support frame 1 adopts a "day" - shaped frame structure, which has the characteristics of simple structure, stable and reliable, and strong bearing capacity, providing a good foundation for the installation and connection of other components. At the same time, by setting structures such as connecting ear plates, it facilitates the connection and installation of components such as the upper guide wheel set 3, the lifting mechanism 8, and the lower guide wheel set 4, improving the overall performance and reliability of the transfer trolley.

[0058] As Figure 1 , Figure 3As shown in the figure, the lifting suspension column 2 is arranged outside the support frame 1. The support frame 1 and the lifting suspension column 2 are slidably connected through the polytetrafluoroethylene plates provided respectively, and the polytetrafluoroethylene plates are fixedly connected to the support frame 1 and the lifting suspension column 2 by bolts. The lifting suspension column 2 includes an inner frame and a platform frame.

The reduction motor 502 is then lifted using the truck crane and mounted to the box body 501 using the tenth connecting bolt 5011.

[0075] Step 3: Install the support frame 1. The various components of the support frame 1, including the first upper crossbeam 101, the first middle crossbeam 102, the first lower crossbeam 103 and the first side beam 104, are processed in the factory, welded into a whole, and transported to the hoisting area of ​​the construction site. The lower guide wheel group 4 is installed on site and connected to the lower guide wheel seat 401 using the seventh connecting bolt 4011. A car crane is used to lift the main structure of the support frame 1 on site, and a guide chain is used to assist in positioning during construction. The first connecting ear plate 1011 of the first upper crossbeam 101 is connected to the upper guide wheel group 3 through a pin shaft, and the middle part of the first side beam 104 is connected to the connecting seat 506 of the running wheel box 5 through the second connecting bolt 1041.

[0076] Step 4: Install the lifting column 2. The second upper crossbeam 201, second middle crossbeam 202, second lower crossbeam 203, second side beam 204, folding beam 205, platform beam 206, rotating beam 207, and pan cylinder 208 of the lifting column 2 are fabricated at the factory, welded together, and transported to the construction site's hoisting area. A truck crane is used to lift the main structure of the lifting column 2 onto the side of the support frame 1. After accurate positioning, another truck crane is used to install the reverse hook assembly 6. The reverse hook assembly 6 is inserted into the first side beam 104 of the support frame 1. The reverse hook assembly 6's reverse hook bracket 601 is connected to the second side beam 204 of the lifting column 2 using the thirteenth connecting bolt 6011 and the third connecting bolt 2041.

Simultaneously, the second middle crossbeam 202 is connected to the first middle crossbeam 102, and the second side beam 204 is slidably engaged with the first side beam 104.

[0077] Step 5: Install the rotating sling 7. The rotating sling 7 is manufactured in the factory and transported to the construction site's hoisting area. A truck crane with an auxiliary guide chain is used to hoist the rotating sling 7. The rotating spindle 701 is passed through the rotating beam 207 of the lifting column 2. The rotating seat 7011 and handle pin 7012 are installed on site. They are connected to the horizontal rotation cylinder 208 via the cylinder pin 7013. Finally, the sling 702 is connected to the hook plate 703.

[0078] Step 6: Install the lifting mechanism 8. Hoist the oil cylinder 802 to the installation position on site and temporarily fix it with a guide chain. The upper part is connected to the first middle crossbeam 102 using the upper oil cylinder pin 803, and the lower part is connected to the second middle crossbeam 202 using the lower oil cylinder pin 801.

[0079] In summary, the inverting trolley provided in the embodiment of the present invention successfully solves the problem of complex operation of moving the traditional mobile formwork forward through the hole of the pier-side bracket by integrating 3600 full-angle rotation, vertical movement and longitudinal movement into an integrated structure, thereby greatly improving construction efficiency and reducing overall costs. Specifically, the lifting mechanism and the lifting column are connected by an oil cylinder to realize the vertical movement of the pier-side bracket components, and the rotating sling clamps the main beam top plate. By rotating the main shaft, 3600 full-angle rotation can be achieved, which can avoid the supporting trestle and the completed main pier, and the running wheel box can move longitudinally along the guide beam and the main beam track. The functional units work together to form a complete load-bearing system, which not only meets the three-dimensional freedom of movement requirements, but also significantly improves the turnover utilization rate of the inverting trolley through standardized component design, and ultimately achieves the effect of shortening the construction period and saving construction costs. The inverting trolley adopts a fully assembled design, and each core component is modularly connected by bolts and pins, which is easy to assemble and disassemble and has high reliability.
