[0031] Therefore, the following solutions are proposed:
[0032] See Figure 4This utility model provides a pile driver support structure 100 for supporting a pile driver 200 on a hull 300. The pile driver 200 includes a frame 210, a pile lifting platform 220, a secondary pile frame 230, and a hammer platform 240. The frame 210 is an integral truss structure with an isosceles inverted triangular cross-section, extending from the bow to the stern of the hull 300. In this utility model, the pile driver support structure 100 includes a support device 110 located at the stern of the pile driver for supporting the frame 210 of the pile driver 200, and two lower hinge seats 120 located at the bow of the pile driver.
[0033] Combination Figure 5 In the piling vessel pile frame support structure 100 provided by this utility model, the support device 110 includes a support bracket 111 and a pile frame connecting frame 112 located on the support bracket 111 and connected to the pile frame 200 frame body 210. Two parallel supports 112a are provided at the bottom of the pile frame connecting frame 112. These two parallel supports 112a are parallel to the extension direction of the pile frame 200 frame body 210 and are symmetrically arranged to the left and right of the frame body 210. According to the solution of this utility model, by providing two parallel supports 112a at the bottom of the pile frame connecting frame 112, two support points are formed at the stern, so that the piling vessel pile frame support structure 100 forms a support form with four supports in the entire pile frame 200: the two support points at the stern and the two lower hinge seats 120 at the bow. Compared with the existing three-point support form, the pile frame 200 is more stable during towing.
[0034] Furthermore, in the pile frame support structure 100 of the piling vessel provided by this utility model, two parallel supports 112a are provided at the bottom of the pile frame connecting frame 112 of the support device 110, and their bottom surfaces are generally arc surfaces D (e.g., Figure 6 As shown), and on the top plane of the support bracket 111 of the support device 110, there are two support parts 111a that contact the two parallel supports 112a of the pile frame connecting frame 112. When the pile frame 200 tilts back and forth, on the support device 110, the two parallel supports 112a at the bottom of the pile frame connecting frame 112 and the two support parts 111a on the top plane of the support bracket 111 always maintain arc surface D contact. Compared with the planar contact method, it can effectively prevent the pile frame 200 from being squeezed and damaged by the support bracket 111 of the support device 110 when it tilts back and forth during towing.
[0035] In some embodiments, the two support portions 111a on the top plane of the support bracket 111 of the support device 110 may be located on the top plane or may be two protrusions protruding from the top plane. In some embodiments, the support portion 111a may also have a lateral abutment portion 111b.
[0036] In some embodiments, a nylon plate 111c is fixed to each of the two support portions 111a for wear prevention. The fixing method can be bolt fixing or other known methods, such as adhesive fixing.
[0037] like Figure 4 , Figure 5 , Figure 7 and Figure 8 As shown, in the pile support structure 100 of the piling vessel provided by this utility model, the pile frame 200 of the piling vessel includes, from bottom to top, a frame 210, a pile lifting platform 220, a secondary pile frame 230, and a hammer platform 240. The frame 210 is an isosceles inverted triangular cross-section truss structure that extends from the bow to the stern of the hull 300. It includes two upper main pipes 211, one lower main pipe 212, and several horizontal support pipes 213. The pile frame connecting frame 112 of the support device 110 includes an upper horizontal pipe 1121 that connects the left and right upper main pipes 211, two lower inclined pipes 1122 that are connected to the lower main pipe 212 in a V-shape, and two connecting pipes 1123 that connect the two ends of the upper horizontal pipe 1121 and the lower inclined pipe 1122 on the same side. In some embodiments, the pile frame connecting frame 112 of the support device 110 further includes several reinforcing pipes 1124 that connect the middle part of the upper horizontal pipe 1121 and the middle part of the connecting pipe 1123, connect the middle parts of the two connecting pipes 1123 and / or connect the middle parts of the two connecting pipes 1123 and the two ends of the lower inclined pipe.
[0038] In some embodiments, the bottom of the end of the inclined pipe 1122 and the end of the connecting pipe 1123 are connected to the two parallel supports 112a, that is, the end of the inclined pipe 1122 and the end of the connecting pipe 1123 are placed on the two parallel supports 112a. By placing the extended ends of the two inclined pipes 1122 connected to the lower main pipe 212 of the frame 210 of the piling vessel 200 on the two parallel supports 112a, the frame 210 of the piling vessel 200 is placed on the support bracket 111 of the support device 110.
[0039] In some embodiments, the pile frame connecting frame 112 further includes two straight pipes 1125 connecting the two ends of the inclined pipe 1122 to the pile platform 220 and a connecting pipe 1126 connecting the two straight pipes 1125, so as to further fix the pile frame connecting frame 112 to the pile frame 200 of the piling vessel.
[0040] like Figure 4 , Figure 5As shown, in the piling vessel support structure 100 provided by this utility model, the support bracket 111 of the support device 110 includes four support tubes 1111 that are symmetrically arranged in an isosceles trapezoidal shape with respect to the left and right sides of the piling vessel frame 200 body 210 and are tapered with respect to the extension direction of the frame 210. In some embodiments, the support bracket 111 of the support device 110 further includes several supporting reinforcing tubes 1112 that connect the top and middle of the support tubes 1111, connect the middle parts of the four support tubes 1111, and / or connect the bottom and middle parts of the support tubes 1111. The arrangement of the support tubes 1111 and the supporting reinforcing tubes 1112 makes the structure of the support bracket 111 of the support device 110 more stable.
[0041] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
