Description

Technical Field

[0001] This utility model relates to the field of frame bridge construction technology, and in particular to a formwork trolley device for frame bridges. Background Technology

[0002] As a common bridge structure, the frame bridge is constructed by rigidly connecting the superstructure (such as beams or slabs) with the substructure (including piers and abutments) to create a unified, collaboratively load-bearing bridge system. In terms of appearance, the structural features of a frame bridge are quite similar to those of a portal or box-shaped frame. Regarding dimensions, the transverse length of a frame bridge is typically greater than its longitudinal length.

[0003] In current construction scenarios, given the generally large lateral spans of frame bridges, formwork trolleys are typically used to improve construction efficiency. The conventional approach involves installing steel wheels at the bottom of the trolley, placing these wheels on steel rails laid on the ground, and relying on the wheels rolling along the rails to move the entire trolley. However, in actual parallel rail laying, various factors make it difficult to achieve the ideal rail spacing. This leads to frequent rail wear between the steel wheels and rails during trolley movement, hindering trolley movement and severely impacting construction progress and efficiency. Utility Model Content

[0004] The purpose of this utility model is to overcome the problem in the prior art that the steel wheels and steel rails bite each other during the movement of the formwork trolley due to the imperfect spacing of the steel rails, which makes the trolley difficult to move. This utility model provides a formwork trolley device for frame bridges.

[0005] This utility model provides a template trolley device for frame bridges, comprising:

[0006] The first crossbeam, with a first template connected above it;

[0007] The first column is located at both ends of the first crossbeam, and the top of the first column is connected to the first crossbeam; a second template is connected to the outside of the first column.

[0008] The second crossbeam has its two ends connected to the bottom of the first column located at both ends of the first crossbeam.

[0009] The second column is hinged at the top to the bottom of the first column;

[0010] A base beam is connected to the bottom end of the second column, and the base beam is perpendicular to both the first crossbeam and the first column; a walking component is provided at the bottom of the base beam.

[0011] The telescopic component has two ends hinged to the second crossbeam and the base beam, respectively.

[0012] A steel rail, which is used to be laid along a construction path, and a traveling component that can travel along the steel rail.

[0013] This utility model provides a formwork trolley device for a frame bridge. A first crossbeam, a first column, and a second crossbeam together form the skeleton of the formwork trolley, supporting the entire trolley. The first crossbeam supports the first template, which is used to shape the bottom of the upper structure of the frame bridge. The first column supports the second template, which is used to shape the inner side of the lower structure of the frame bridge. The second column connects the first column to the base beam. The traveling component at the bottom of the base beam drives the entire formwork trolley to move along the rails, thereby enabling rapid transfer of the formwork trolley between different construction sections.

[0014] Because the top of the second column is hinged to the bottom of the first column, and both ends of the telescopic component are hinged to the second crossbeam and the base beam respectively, when the telescopic component extends or retracts, it causes the first column, the base beam, and the traveling component to rotate as a whole around the hinge point between the first and second columns. This allows adjustment of the distance between the traveling components on both sides of the template trolley, enabling fine-tuning of the traveling components according to the spacing between the laid rails, matching them to the rail spacing, effectively reducing rail wear and thus solving the problem of difficult trolley movement.

[0015] This utility model, by setting the telescopic component and connecting the top of the second column to the bottom of the first column in a hinged manner, can flexibly adjust the distance between the traveling components on both sides of the template trolley, thereby effectively avoiding the phenomenon of the traveling components biting the rails and ultimately solving the problem of the trolley's movement difficulty.

[0016] The telescopic component can be a mechanical telescopic component or a hydraulic telescopic component.

[0017] Preferably, the traveling component includes a steel wheel, the top of the cross-section of the rail is arc-shaped, and the rim surface of the steel wheel matches the arc-shaped top of the rail. In this design, when the steel wheel rotates at a certain angle around the axis of the rail, the rim surface of the steel wheel can still closely fit with the top of the rail, maintaining good contact, thereby ensuring that the steel wheel can continuously and stably roll normally along the rail.

[0018] Preferably, the telescopic component is a hydraulic telescopic rod. Compared to mechanical telescopic components, the hydraulic telescopic rod not only has a stronger force output capability, but also performs better in terms of control precision, effectively improving the overall stability and reliability of the template trolley's operation.

[0019] Preferably, the angle between the telescopic component and the second crossbeam is 30°-60°.

[0020] Preferably, the first crossbeam is connected to the first template via a plurality of first telescopic rods; the first column is connected to the second template via a plurality of second telescopic rods. In this design, the plurality of first telescopic rods allow the first template to be moved away from or closer to the upper structure of the frame bridge, facilitating the rapid erection or dismantling of the bottom template of the upper structure. Similarly, the plurality of second telescopic rods allow the second template to be moved away from or closer to the lower structure of the frame bridge, facilitating the rapid erection or dismantling of the inner template of the lower structure.

[0021] Preferably, a third template is provided between the first template and the second template, and the two opposite sides of the third template are respectively hinged to the first template and the second template; the third template is connected to the end of the first crossbeam adjacent to it by a third telescopic rod.

[0022] This solution utilizes the third template to connect the first and second templates. Specifically, the opposite sides of the third template are hinged to both the first and second templates. This hinged connection provides flexibility, allowing the angles between the first and third templates, as well as between the second and third templates, to vary within a certain range. This ensures that the first and second templates do not interfere with each other during erection and dismantling.

[0023] The first telescopic rod, the second telescopic rod, and the third telescopic rod can all be hydraulically driven telescopic rod structures, or they can be telescopic rod structures based on threaded connections to achieve telescopic functions.

[0024] Preferably, the bottom of the base beam is provided with several telescopic supports, the tops of which are connected to the base beam, and the bottom of each telescopic support has a telescopic head. In this design, when the telescopic head is extended, it contacts the ground. At this time, the several telescopic supports will jointly bear the load of the entire formwork trolley, ensuring the stability of the formwork trolley during operation. When it is necessary to move the formwork trolley, the telescopic head can be switched to the retracted state, disengaging it from the ground. In this way, the several telescopic supports will not obstruct the movement of the formwork trolley, ensuring smooth movement.

[0025] Preferably, both ends of the base beam are equipped with ground support rods, and the two ends of the ground support rods are connected to the base beam and the ground, respectively. In this design, the ground support rods are used to fix the entire formwork trolley to the ground, effectively preventing relative displacement between the formwork trolley and the ground, and ensuring the stability and safety of the formwork trolley during operation. When it is necessary to move the formwork trolley, simply disconnect the ground support rods from the ground, and the formwork trolley can be moved freely, making the operation convenient and efficient.

[0026] Preferably, a diagonal brace is provided between the first crossbeam and the first column. In this design, the diagonal brace strengthens the connection between the first crossbeam and the first column. Furthermore, the first crossbeam, the first column, and the diagonal brace together form a stable triangular structure, thereby further enhancing the overall stability and reliability of the template trolley.

[0027] Preferably, both the first and second telescopic rods include a sleeve and two screws. The sleeve has internal threads at both ends, with opposing threads on each side. The two screws are connected to the internal threads at both ends of the sleeve, and the ends of the two screws furthest from the sleeve are hinged to corresponding components. Compared to hydraulically driven telescopic rod structures, this design achieves telescopic functionality through threaded engagement, resulting in lower manufacturing and maintenance costs.

[0028] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0029] This utility model provides a template trolley device for frame bridges. By setting the telescopic component and connecting the top of the second column to the bottom of the first column in a hinged manner, the distance between the traveling components on both sides of the template trolley can be flexibly adjusted, thereby effectively avoiding the phenomenon of rail biting between the traveling components and the rails, and ultimately solving the problem of difficult trolley movement.
