Problems solved by technology

[0005] The above two caisson transport devices can improve the efficiency of caisson jacking to a certain extent, but because it is difficult to ensure the flatness of the bottom surface of the cover plate where the bottom surface of the caisson and the top surface of the trolley are in contact with the top surface of the trolley during the movement of the caisson, and because The running track of the trolleys is affected by factors such as foundation settlement and installation deviation, and the force of the two trolleys is not balanced, resulting in a large pressure difference between the two trolleys, which in turn affects the reliability of the trolleys moving the caisson

Embodiment 1

[0029] The invention discloses a capsule trolley jacking device, see Figure 1-Figure 3 , the jacking device is composed of a plurality of trolley units, and each trolley unit includes a base frame 4, a jacking support box 3, a jacking capsule 2 and a caisson lifting plate 1.

[0030] The base frame 4 is installed on the track 13 through the wheel rail 12, the jacking support box 3 is installed on the base frame 4, the jacking capsule 2 is arranged in the box, and the caisson lifting plate 1 is installed on the jacking support box 3 The top can be lifted by the jacking capsule 2, and the jacking support box 3 is provided with a pipeline, and the pipeline is connected with the nozzle of the jacking capsule 2.

[0031] The upper surface of the base frame 4 is provided with a groove with a trapezoidal cross-section, and the surface of the groove is provided with a ring-shaped embedded hole 6, and a protrusion matching the groove is provided on the lower surface of the jacking sup...

Embodiment 2

[0049] The structural composition of the capsule trolley jacking device of embodiment 2 is basically the same as that of the capsule trolley jacking device of embodiment 1, and the distinguishing features are:

[0050] The length of the multi-columnar force-regulating rubber pad is 1.2m, the width is 2.4m, and the thickness is 50mm. The number of cylindrical rubber bodies is 200. The cylindrical rubber body base adopts a cylindrical structure with a diameter of 100mm. The number of layers of the inner rib spiral structure is 5 layers, and the number of layers of the outer rib ring structure is 5 layers.

[0051] Table 1 shows the compression amount of the backing plate of the prior art and the backing plate of the present invention when the same pressure value is applied.

Embodiment 3

[0057] The structural composition of the capsule trolley jacking device of embodiment 3 is basically the same as that of the capsule trolley jacking device of embodiment 1, and the distinguishing features are:

[0058] The thickness of the steel backing plate 18 laid in blocks on both sides below the rail 17 is 20 mm. The steel backing plate 18 is provided with height-adjusting bolts 19 to adjust the elevation to improve the installation accuracy and ensure that the elevation deviation of the steel rail 17 of the same section is controlled within 2 mm. The height difference range within any 30 meters of the rail axis is controlled within 5mm.

[0059] Between the rail 17 and the steel backing plate 18, the thickness of the track rubber backing plate 20 is 7 mm, and the leveling height difference between the rail 17 and the steel backing plate 18 is 3 mm, which can make up for the difference between the rail and the supporting surface. The height difference ensures the balance ...

Abstract

The invention relates to a trolley jacking device, and in particular to a rubber-bag trolley jacking device and a method for jacking and transporting caisson. The jacking device is provided with a multi-column-shaped force-regulating rubber base plate to regulate the pressure difference between the bottom face of the caisson and the bottom face of a cover plate making contact with the top faces of trolleys, reduce the pressure differences among all the trolleys and guarantee that stress of all the trolleys is within the range of ultimate bearing capacity, and it is guaranteed that the caisson is transported safely. The multi-column-shaped force-regulating rubber base plate is internally provided with internal reinforcing ribs and external reinforcing ribs, so that the elasticity of the multi-column-shaped force-regulating rubber base plate is improved, the amount of compression of the multi-column-shaped force-regulating rubber base plate at the ultimate pressure value is reduced, and the service life of the multi-column-shaped force-regulating rubber base plate is greatly prolonged.

Description

technical field [0001] The invention relates to a trolley jacking device, in particular to a capsule trolley jacking device and a method for jacking out and transporting a caisson. Background technique [0002] The caisson is an indispensable and important part of the offshore structure. At present, in the process of port engineering construction, the following two methods are generally used for lifting and transporting the caisson: [0003] 1. Utilize the air bag to complete the caisson shipment. For example, Chinese Patent No. CN10323729A discloses a method for jacking up a large caisson. For flat airbags, iron or wooden templates are laid between adjacent flat airbags; prefabricated caissons are prefabricated on the surface of flat airbags and pads; jacking, after the caisson is prefabricated, the flat airbags are inflated at the same time, and the jacking is 15- 25cm, the caisson is separated from the block, and a support device is placed at the bottom of the caisson; t...
