Description

Technical Field

[0001] The utility model relates to the technical field of swivel bridge support legs, and in particular to an adjustable swivel bridge support leg. Background Art

[0002] A rotating bridge is a bridge constructed using the rotation method. Bridge rotation construction refers to a construction method in which the bridge structure is formed at a position other than the design axis and then rotated into place. The most critical device in this construction method is the rotation system, which requires the use of support legs.

[0003] According to a seismic swivel bridge support foot disclosed in the patent number CN211368432U, the device replaces the lower section of the support foot in the conventional support foot with a shock-absorbing support, and is connected and fixed with the lower turntable. It can not only play an anti-overturning role in the bridge rotation stage, but also play a bearing and seismic role after the bridge is completed, and the construction is simple and the adaptability is strong;

[0004] However, although the device can achieve the purpose of earthquake resistance during use, the height of the device cannot be adjusted according to demand, so that the device cannot meet different usage requirements. Because the swivel bridge has particularly strict requirements on height deviation, it needs to be in a relatively horizontal position. The existing support legs cannot be adjusted in height, which is more troublesome when leveling, reducing the practicability of the device.

[0005] According to the patent disclosed in patent number CN220035219U, a support ring, a limit groove, a ball and a guide rail are added on the original basis. When the upper platform is installed on the lower platform, the guide rail at the bottom of the upper platform is placed on the top of the ball. When the bridge body needs to be rotated, the guide rail at the bottom of the upper platform is displaced on the ball, and the ball rolls in the limit groove, so that the upper platform is driven to rotate by the ball, thereby avoiding the situation that the upper platform is stuck on the lower platform when the upper platform is rotated;

[0006] However, the device is also unable to adjust the height. When performing leveling, the staff needs to gradually change the height of the support legs for adjustment, which is troublesome during adjustment and reduces the practicality of the device. Utility Model Content

[0027] See also Figure 1 to Figure 3 The fixed tube 2 is made of steel with high hardness and can withstand greater gravity without breaking, which can ensure the service life of the device and effectively increase the safety of the device. The connection between the base plate 1 and the fixed tube 2 is relatively stable, avoiding the danger caused by the fixed tube 2 falling off. The two fixed tubes 2 can be connected as a whole through the base plate 1, which can increase the stability and safety of the device.

[0028] A lifting cylinder 3 is arranged above the fixed cylinder 2, and a sealing ring 4 slidably connected to the fixed cylinder 2 is installed on the bottom surface of the lifting cylinder 3. A connecting plate 5 for increasing the stability of the lifting cylinder 3 is arranged above the bottom plate 1, and the outer surfaces of the two lifting cylinders 3 are fixedly connected to the inner wall of the connecting plate 5.

[0029] See also Figure 1 to Figure 3 The lifting cylinder 3 has the same size as the fixed cylinder 2, which can make the device more stable and safe. The fixed cylinder 2 and the sealing ring 4 have good sealing performance, which will not cause concrete leakage and can increase the safety of the device. The connecting plate 5 can be used to connect the two lifting cylinders 3, so that the two lifting cylinders 3 can move synchronously, ensure that the two lifting cylinders 3 are on the same horizontal line, ensure that the device will not be damaged due to the inclination of the lifting cylinder 3, and can effectively increase the practicality of the device.

[0030] Two adjustment mechanisms 6 are arranged above the base plate 1 . The adjustment mechanism 6 includes a double-axis jack 601 operated by a driving device. Both output ends of the double-axis jack 601 are fixedly connected to a moving rod 602 .

[0031] See also Figure 1 to Figure 4The dual-axis jack 601 can drive the two moving rods 602 to move synchronously, avoiding the device from tilting during the adjustment process, ensuring that the device will not be damaged due to tilting, and effectively increasing the safety of the device. The dual-axis jack 601 can generate a large thrust to ensure the normal operation of the device. This application does not impose too many restrictions on the model of the dual-axis jack 601, and the dual-axis jack 601 can be customized according to needs.

[0032] The upper surface of the base plate 1 is hinged with a first hinge rod 603 via a pin, the bottom surface of the connecting plate 5 is hinged with two second hinge rods 604 via a pin, the bottom end of the second hinge rod 604 is hinged to the top end of the first hinge rod 603 via a pin, the outer surface of the first hinge rod 603 is hinged with a first connecting rod 605 connected to the moving rod 602 via a pin, and the outer surface of the second hinge rod 604 is hinged with a second connecting rod 606 connected to the moving rod 602 via a pin.

[0034] A lifting plate 607 for supporting the dual-axis jack 601 is arranged above the base plate 1. The upper surface of the lifting plate 607 is fixedly connected to the bottom surface of the dual-axis jack 601.

[0045] Two first fixing rods 11 are arranged above the base plate 1 to increase the stability of the first hinged rod 603. The two ends of the first fixing rod 11 are respectively fixedly connected to the side surfaces of the two first hinged rods 603 that are close to each other. The first fixing rod 11 can be used to connect the two first hinged rods 603, thereby ensuring that the two first hinged rods 603 move synchronously and avoiding deviation of the device during adjustment.

[0046] The first fixing rod 11 is made of a material with relatively high hardness, so as to avoid the first fixing rod 11 from breaking during use of the device, thereby effectively increasing the safety of the device.

[0047] Two second fixing rods 12 are arranged above the base plate 1 to increase the stability of the second hinged rod 604. The two ends of the second fixing rod 12 are respectively fixedly connected to the side surfaces of the two second hinged rods 604 that are close to each other. The second fixing rod 12 can increase the stability of the second hinged rod 604, and can make the second hinged rod 604 move synchronously, thereby ensuring the safety of the device during operation.

[0048] The second fixing rod 12 and the second hinge rod 604 are fixed by welding, which can make the connection more stable and prevent the device from falling off during use, thereby effectively increasing the stability of the device during operation.

[0049] Working principle: When in use, it is first necessary to install the required number of devices according to needs, and then the staff needs to perform leveling work to ensure that all devices are in the same plane. When the device needs to be adjusted, it is necessary to start two double-axis jacks 601. The double-axis jacks 601 can drive the moving rod 602 to move, and then the first connecting rod 605 can drive the first hinged rod 603 to move, and the second connecting rod 606 can drive the second hinged rod 604 to move, which will cause the hinge between the first hinged rod 603 and the second hinged rod 604 to rise and fall, thereby driving the double-axis jack 601 to rise and fall through the moving rod 602, and the lifting and falling of the double-axis jack 601 can drive the lifting plate 607 to rise and fall, thereby achieving the purpose of adjusting the height of the device, so that all devices are on the same horizontal line, and then the steel bars 7 and steel wires 8 are tied inside the lifting cylinder 3, and then concrete is poured inside the lifting cylinder 3, so as to achieve the fixation of the device, avoid deformation of the device during the support process, and effectively increase the safety of the device.
