Problems solved by technology

However, the surface shape of the seabed is generally undulating. If the integral or bifurcated pile leg structure is still used, the support will be unstable or even slip, which will cause greater danger to the entire operating platform.
[0003] The spud legs with integral spud cans, because of the larger size of the spud cans, can ensure that the spud cans can be inserted into the seabed at a shallower depth, which is conducive to pile extraction, but when the seabed is not very flat, this structure still cannot guarantee vertical stability ;Using the bifurcated spud cans structure, although the large spud cans can be turned into several auxiliary spud cans, but because the auxiliary spud cans are simultaneously unfolded structures and their own lengths cannot be adjusted, the ideal support effect cannot be achieved
[0004] The present invention is an improvement made to address the defects of large volume and poor support stability of the integral spud can in the prior art and the inappropriate length of the auxiliary spud can of the bifurcated spud can

Embodiment 1

[0013] Example as figure 1 As shown, an all-terrain leg, the all-terrain leg includes a main leg 1, an auxiliary leg and a support plate 8, and the auxiliary leg is installed on the main leg 1 through a nut 2 and a first pin shaft 3 on the connecting frame; the connecting frame is provided with at least one connecting frame pin hole, and the top of the auxiliary leg has at least one pin hole on the top of the auxiliary leg matching the connecting frame pin hole; the auxiliary leg passes through the The pin hole at the top of the auxiliary leg and the pin hole of the connecting frame are fixed with the first positioning pin 5; At the bottom of the auxiliary leg, the support plate 8 includes a support plate pin hole, through which one of the plurality of auxiliary leg bottom pin holes and the support plate pin hole is fixed with a second positioning pin 10, thereby adjusting the angle of the support plate . The bolt hole of the connecting frame is arranged on the connecting fr...

Embodiment 2

[0017] Example two such as figure 1 As shown, a method for using all-terrain legs: when the all-terrain legs arrive at a designated position, put down the all-terrain legs so that the main legs 1 are in contact with the seabed or river bed; Pull out the first positioning pin 5, adjust the angle of the auxiliary leg according to the topography of the seabed or river bed and insert the first positioning pin 5; pull out the second positioning pin 10, adjust the angle of the auxiliary leg according to the topography of the seabed or river bed Adjust the angle of the support plate 8 and insert the second positioning pin 10 . When the operation of the all-terrain legs is completed, the main legs 1 are lifted, and when the all-terrain legs are out of contact with the riverbed or seabed, the second positioning pin 10 is pulled out to adjust the support plate 8 to the folded position, and then insert the second positioning pin 10; pull out the first positioning pin 5, adjust the angle...

Embodiment 3

[0018] Embodiment three such as figure 2 As shown, an all-terrain leg, the all-terrain leg includes a main leg 1, an auxiliary leg and a support plate 8, and the auxiliary leg is installed on the main leg 1 through a nut 2 and a first pin shaft 3 on the connecting frame; the connecting frame is provided with at least one connecting frame pin hole, and the top of the auxiliary leg has at least one pin hole on the top of the auxiliary leg matching the connecting frame pin hole; the auxiliary leg passes through the The pin hole at the top of the auxiliary leg and the pin hole of the connecting frame are fixed with the first positioning pin 5; At the bottom of the auxiliary leg, the support plate 8 includes a support plate pin hole, through which one of the plurality of auxiliary leg bottom pin holes and the support plate pin hole is fixed with a second positioning pin 10, thereby adjusting the angle of the support plate . The bolt hole of the connecting frame is arranged on th...

Abstract

The invention provides an all-terrain pile leg and an all-terrain pile leg application method. The all-terrain pile leg comprises a main pile leg unit, auxiliary leg units and supporting discs. The auxiliary leg units are mounted on a connection rack of the main pile leg unit through a nut and a first pin shaft. The supporting discs are mounted at the bottoms of the auxiliary leg units through second pin shafts. The all-terrain pile leg can fix the auxiliary leg units and the supporting discs through pinholes and positioning pins. The angle and the length of the each auxiliary leg unit can be adjusted, and the angle of each supporting disc also can be adjusted. The all-terrain pile leg is small in size and is applicable to different terrains. According to the invention, the supporting stability of the pile leg is improved, the horizontal sliding resistance capability is improved, the moving resistance of the pile leg is reduced, and the power cost is saved.

Description

technical field [0001] The invention relates to the technical field of manufacturing marine engineering equipment, in particular to an all-terrain pile leg. Background technique [0002] When the mobile offshore operation platform is supported on a relatively flat seabed, a general pile leg structure can be used. However, the surface shape of the seabed is generally undulating. If the integral or bifurcated pile leg structure is still used, the support will be unstable or even slip, which will cause greater danger to the entire operation platform. [0003] The spud legs with integral spud cans, because of the larger size of the spud cans, can ensure that the spud cans can be inserted into the seabed at a shallower depth, which is conducive to pile extraction, but when the seabed is not very flat, this structure still cannot guarantee vertical stability ; With the bifurcated spud-can structure, although the large spud-can can be transformed into several auxiliary spud-cans, ...
