Description

Technical Field

[0001] The utility model relates to the technical field of cantilever casting bridge construction equipment, in particular to a bottom basket device with adjustable angle. Background Art

[0002] The hanging basket is a special construction equipment used to bear the deadweight of the beam and move forward section by section in the cantilever bridge construction. The cantilever bridge construction machine is a hanging basket equipment with the main load-bearing rods located below the beam surface and only one load-bearing rear upper crossbeam on the beam surface.

[0003] Among them, the bottom basket system of the hanging basket directly bears the gravity load of the suspended beam section and other loads such as the formwork. However, when the hanging basket is working in the air, the bottom basket system needs to be adjusted to a suitable height and tilted to a suitable angle. For example, Chinese patent CN115288040A discloses a hanging basket bottom formwork support system that can automatically adjust the angle. After a section is cast, the hanging basket moves forward and into place, and the front and rear suspension rods are lifted according to the measurement and lofting results to adjust the elevation of the front lower beam and the rear lower beam; the bottom formwork and the longitudinal beam are hingedly connected to the front lower beam and the rear lower beam, and the angle is automatically adjusted as the elevation of the front lower beam and the rear lower beam changes, so as to fit the linear shape of the bottom plate of the variable-section continuous box beam. However, this method of lifting the front and rear suspension rods to adjust the elevation is difficult to adjust and has low adjustment accuracy.

[0004] Therefore, a new bottom basket system with adjustable angle is proposed, which is applied to the construction with process requirements on bridge curves, making the construction operation simpler and safer. Utility Model Content

In the utility model, the angle-adjustable bottom basket device has one side of the crossbeam assembly 100 along the longitudinal direction of the cantilever cast bridge, which is hingedly connected to the longitudinal beam assembly 200, and the other side of the crossbeam assembly 100 along the longitudinal direction of the cantilever cast bridge is supported and connected to the longitudinal beam assembly 200 by an angle adjustment mechanism 400; the angle adjustment mechanism 400 is supported and adjusted to control the relative angle between the longitudinal beam assembly 200 and the crossbeam assembly 100, and then the inclination angle of the bottom mold assembly 300 is adjusted, so that the bottom mold assembly 300 fits the bottom curve of the cantilever cast bridge; in addition, since the crossbeam assembly 100 can be stably in a relatively horizontal state during the entire operation process, a working platform is laid on the crossbeam assembly 100, so that the angle adjustment mechanism 400 can be accurately adjusted on the working platform, so that the bottom mold assembly 300 can be completely fitted to the bottom inclination angle of the cantilever cast bridge; then the bottom mold assembly 300 is used to achieve fitting to the bottom curve of the cantilever cast bridge.

[0029] like Figure 1 and Figure 2As shown, in this embodiment, the angle adjustment mechanism 400 includes a first ear seat 401 arranged on the cross beam assembly 100, a first screw rod 402 rotatably connected to the first ear seat 401, a first rotation adjustment nut 403 threadedly connected to the first screw rod 402, an adjustment sleeve 404 fixedly connected to the first rotation adjustment nut 403, a second rotation adjustment nut 405 fixedly connected to the adjustment sleeve 404, a second screw rod 406 threadedly connected to the second rotation adjustment nut 405, and a second ear seat 407 rotatably connected to the second screw 406, and the second ear seat 407 is arranged on the longitudinal beam assembly 200. The angle adjustment mechanism 400 adopts a structural form in which both ends are respectively hinged to the cross beam assembly 100 and the longitudinal beam assembly 200, which can not only provide sufficient degrees of freedom for the relative movement of the cross beam assembly 100 and the longitudinal beam assembly 200, but also constitute certain restrictions on the relative movement trajectory of the cross beam assembly 100 and the longitudinal beam assembly 200 to ensure the stability of the overall structure. The two ends of the adjusting sleeve 404 are respectively provided with different-direction thread structures, and the first screw rod 402 and the second screw rod 406 at the two ends are respectively extended or shortened synchronously by rotating the adjusting sleeve 404, so as to achieve the precise adjustment of the angle between the cross beam assembly 100 and the longitudinal beam assembly 200. According to the designed bottom surface inclination angle of the cantilever cast bridge, the longitudinal beam assembly 200 and the bottom mold assembly 300 on the longitudinal beam assembly 200 can be directly adjusted to the inclination angle matching the bottom surface of the cantilever cast bridge, and the operating platform can be built on the cross beam assembly 100, and the operator can monitor on the operating platform to ensure that the angle is adjusted in place. Optionally, at least one of the first screw rod 402, the adjusting sleeve 404, and the second screw rod 406 is provided with a size scale for precise adjustment. Optionally, the thread direction of the first screw 402 and the first rotation adjustment nut 403 is opposite to the thread direction of the second rotation adjustment nut 405 and the second screw 406, that is, the rotation direction is opposite, and when the adjustment sleeve 404 is rotated, the first screw 402 and the first rotation adjustment nut 403 and the second rotation adjustment nut 405 and the second screw 406 are synchronously extended or shortened. Optionally, the connection between the first screw 402 and the first rotation adjustment nut 403 can also be replaced by a fixed-point rotation fit, that is, when the adjustment sleeve 404 is rotated, only the second rotation adjustment nut 405 and the second screw 406 are extended or shortened. Optionally, the first screw 402 and the first rotation adjustment nut 403 are removed, and the adjustment sleeve 404 can be arranged in a fixed-point rotation manner, that is, when the adjustment sleeve 404 is rotated, only the second rotation adjustment nut 405 and the second screw 406 are extended or shortened. Optionally, the connection between the second rotation adjustment nut 405 and the second screw rod 406 may also be replaced by fixed-point rotation cooperation, that is, when the rotation adjustment sleeve 404 is performed, only the first screw rod 402 and the first rotation adjustment nut 403 perform extension or shortening movement.Optionally, the second rotation adjustment nut 405 and the second screw rod 406 are removed, and the adjustment sleeve 404 can be arranged to rotate at a fixed point, that is, when the adjustment sleeve 404 is rotated, only the first screw rod 402 and the first rotation adjustment nut 403 perform extension or contraction movement.

[0030] In this embodiment, the two ends of the angle adjustment mechanism 400 are rotatably connected to the cross beam assembly 100 and the longitudinal beam assembly 200, respectively, and the angle adjustment mechanism 400 adopts a strut. Optionally, the angle adjustment mechanism 400 adopts a cylinder, an oil cylinder or a jack. Different types of angle adjustment mechanisms 400 can be used as needed to ensure the stability of the entire structure while taking into account the control accuracy.

[0031] like Figure 1 and Figure 2 As shown, in this embodiment, multiple groups of angle adjustment mechanisms 400 are provided, and the multiple groups of angle adjustment mechanisms 400 are arranged in parallel and at intervals, and the arrangement direction of the multiple groups of angle adjustment mechanisms 400 is parallel to the hinge axis between the longitudinal beam assembly 200 and the cross beam assembly 100. By arranging multiple groups of angle adjustment mechanisms 400 in the transverse direction of the cantilever cast bridge, it is possible to achieve a flat bottom plane of the cantilever cast bridge through synchronous adjustment, and also to achieve a curved bottom plane of the cantilever cast bridge in the width direction through asynchronous adjustment, so as to have a wider range of applications.

[0032] like Figure 1 and Figure 2 As shown, in this embodiment, the crossbeam assembly 100 includes a connecting longitudinal beam 101, a bottom basket crossbeam 103 and a hanger 102 fixedly connected to the bottom basket crossbeam 103; one of the bottom basket crossbeams 103 is simultaneously connected to the hanger 102 and the hingedly connected longitudinal beam assembly 200, and the other bottom basket crossbeam 103 is simultaneously connected to the hanger 102 and the rotationally connected angle adjustment mechanism 400, and the two bottom basket crossbeams 103 are connected via the connecting longitudinal beam 101. The articulation between the crossbeam assembly 100 and the longitudinal beam assembly 200 and the support adjustment of the angle adjustment mechanism 400 are respectively located on the relatively arranged bottom basket crossbeams 103, and the bottom basket crossbeams 103 are suspended and supported by the hanger 102, so that the forces generated during the angle adjustment process of the longitudinal beam assembly 200 relative to the crossbeam assembly 100 are supported and mechanically transmitted via the suspension support, thereby ensuring the structural stability of the entire adjustment process; in particular, when a working platform is laid on the crossbeam assembly 100, the entire adjustment process will not affect the operators on the working platform, thereby ensuring the safety of the operators' construction operations.

[0033] like Figure 2As shown, in this embodiment, the hanger 102 and the angle adjustment mechanism 400 connected to the bottom basket cross beam 103 are arranged in a staggered manner; since the hanger 102 and the angle adjustment mechanism 400 are both force-applying structures, the hanger 102 is used for suspended movement, and the angle adjustment mechanism 400 is used for support and angle adjustment. Through the staggered arrangement between each other, it is possible to avoid the hanger 102 and the angle adjustment mechanism 400 from obstructing each other, and at the same time, the risk of construction operations can be reduced.

[0034] In this embodiment, the crossbeam assembly 100 also includes a working platform laid on the connecting longitudinal beam 101. Although the longitudinal beam assembly 200 can be adjusted arbitrarily relative to the crossbeam assembly 100, the crossbeam assembly 100 is directly suspended and supported by a structure such as a suspension rod or a suspension arm through a hanger 102, and its structure will not be activated as the longitudinal beam assembly 200 is adjusted. Therefore, when the crossbeam assembly 100 is laid on the working platform, more specifically, when the working platform is laid on the connecting longitudinal beam 101, the stability of the working platform can be guaranteed, thereby ensuring the safety of construction work on the working platform. Optionally, a detachable or foldable guardrail or other structure can also be provided on the connecting longitudinal beam 101 to ensure the safety of work on the working platform.

[0035] like Figure 1 and Figure 2 As shown, in this embodiment, the longitudinal beam assembly 200 includes longitudinal beams 202 arranged in the transverse direction of the cantilever cast bridge, and a connecting crossbeam 203 is provided between the longitudinal beams 202, and the connecting crossbeam 203 is rigidly connected to the adjustment end of the longitudinal beam 202 to connect the longitudinal beams 202 into a whole. Optionally, two adjacent longitudinal beams 202 are fixedly connected by the connecting crossbeam 203. Optionally, a plurality of connecting crossbeams 203 are arranged along the length direction of the longitudinal beams 202, and the connecting crossbeams 203 are combined with the longitudinal beams 202 to form a grid structure.

[0036] like Figure 1 As shown, in this embodiment, the bottom basket device further includes a bottom mold assembly 300, and the bottom mold assembly 300 is arranged on the longitudinal beam assembly 200. Optionally, the bottom mold assembly 300 includes a support 201 arranged on the longitudinal beam 202, and the bottom mold assembly 300 is arranged on the support 201.

[0037] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model.
