Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pile-driving ships, in particular to a device which can enable a forward cable wire rope of a pile-driving ship to climb over a retaining wall. Background Art
[0002] In the process of building a new wharf, it is often encountered that the wharf is very close to the shore. The nearest wharf is only 20m away from the shore. The edge of the revetment is often equipped with a high retaining wall, and it is impossible to set mooring points on the retaining wall. This poses a great challenge to the pile-driving ship in this area.
[0003] Usually, when a pile driver sinks piles at a location very close to the revetment and where there is a retaining wall, the forward cable of the pile driver is crossed over the retaining wall to set a mooring point. However, in the process of crossing the retaining wall, the wire rope is severely worn. At the same time, if there is a notch on the retaining wall, the wire rope is stuck in the notch. When piling, the wire rope is stressed and pops out of the notch, which will also affect the piling accuracy of the pile driver. Utility Model Content
[0004] The utility model aims to solve the deficiencies of the prior art and provides a device which can enable the forward cable wire rope of a pile driving ship to climb over a retaining wall.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a device that can enable the steel wire rope of the forward cable of a pile-driving ship to climb over the retaining wall, comprising: a large rolling shaft, the large rolling shaft is a hollow cylindrical tube structure, the two ends of the large rolling shaft are respectively mounted between two supporting cross bars arranged in the horizontal direction, the supporting cross bars are perpendicular to the axial direction of the large rolling shaft, the two supporting cross bars arranged at the same end of the large rolling shaft are fixedly connected to the middle of the inner side of two supporting vertical poles, two vertical poles are fixedly connected above the large rolling shaft, a small rolling shaft is arranged on the outer sleeve of the vertical pole, and the side surface of the small rolling shaft is a concave surface.
[0006] Furthermore, a steel pipe is sleeved at the middle section of the large rolling shaft, the steel pipe is located between the two columns, and the top of the steel pipe is against the bottom of the small rolling shaft.
[0007] Furthermore, a blocking piece is sleeved on the column, and the blocking piece is pressed on the top of the small rolling shaft.
[0008] Furthermore, a transverse rolling shaft is passed through the inner side of the two supporting uprights, a transverse roller is disposed on the outer side of the transverse rolling shaft, and the transverse roller is mounted on the top surface of the retaining wall.
[0009] Furthermore, the lower ends of the support uprights are fixedly connected with vertical rolling shafts, the outer sleeves of the vertical rolling shafts are provided with vertical rollers, and the vertical rollers are in contact with the side surfaces of the retaining wall.
[0010] The beneficial effects of the utility model are as follows: the utility model solves the problem of serious wear of the steel wire rope when the forward cable of the pile driving ship crosses the retaining wall by arranging a device that can make the steel wire rope slide on the retaining wall, and solves the problem of affecting the pile driving accuracy due to the steel wire rope being unable to bear force.

[0015] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION
[0016] The utility model is further described below in conjunction with the accompanying drawings and embodiments:
[0017] like Figure 1-2 As shown, a device that enables the steel wire rope of the forward cable of a pile-driving ship to climb over a retaining wall comprises: a large rolling shaft 1, the large rolling shaft 1 is a hollow cylindrical structure, the two ends of the large rolling shaft 1 are respectively erected between two horizontally arranged support cross bars 2, the support cross bars 2 are perpendicular to the axial direction of the large rolling shaft 1, the two support cross bars 2 placed at the same end of the large rolling shaft 1 are fixedly connected to the middle of the inner side of two support uprights 3, two uprights 4 are fixedly connected above the large rolling shaft 1, the outer sleeve of the uprights 4 is provided with a small rolling shaft 5, and the side surface of the small rolling shaft 5 is a concave surface. The axial direction of the large rolling shaft 1 is parallel to the wall direction of the retaining wall, the support cross bars 2 are arranged above the retaining wall, the support uprights 3 are placed on both sides of the retaining wall, the steel wire rope of the forward cable of the pile-driving ship passes through the middle of the two small rolling shafts 5, and the steel wire rope and the large rolling shaft 1 fit tightly.
[0018] A steel pipe 6 is sleeved at the middle section of the large rolling shaft 1 . The steel pipe 6 is located between the two upright posts 4 . The top of the steel pipe 6 abuts against the bottom of the small rolling shaft 5 .
[0019] The pillar 4 is sleeved with a blocking piece 7 , and the blocking piece 7 is pressed on the top of the small rolling shaft 5 .
[0020] A transverse rolling shaft 8 is also provided inside the two supporting uprights 3 , and a transverse roller 9 is provided outside the transverse rolling shaft 8 , and the transverse roller 9 is mounted on the top surface of the retaining wall.
