Problems solved by technology

[0003] However, the seabed environment is complex, and the existing reamer control device is complex but has simple functions, which can only realize simple lowering or swinging, which is not conducive to working on the seabed in a complex environment; moreover, most of such ships need to use positioning piles to realize The control of the movement of the ship is extremely inconvenient for moving the ship

Embodiment 1

[0026] Such as figure 1 , 2 As shown, an engineering ship includes a hull 1, a reamer 2, and a reamer control device, and a dredger suction pipe or a cutter suction pump can be arranged behind the reamer.

[0027] The reamer control device comprises a reamer bracket, and the reamer bracket includes a first rack bar 4 and a second rack bar 5 which are parallel to each other, and the upper ends of the first rack bar 4 and the second rack bar 5 are connected on the On the reamer slide block 6, the lower ends of the first frame bar 4 and the second frame bar 5 are rotatably connected to the reamer 2, so that the reamer slide block 6, the first frame bar 4, the second frame bar 5, and the reamer 2 The four actually constitute a parallel four-bar kinematic mechanism. So that when the first rack bar 4 and the second rack bar 5 rotate relative to the reamer slider 6, the orientation of the reamer slider 6 remains unchanged.

[0028] It also includes a support rod 7 intersecting wit...

Embodiment 2

[0039] Such as Figure 8 As shown, the second support rod 5 is a telescopic rod with a controllable length, for example, the expansion and contraction can be controlled by the hydraulic cylinder 134 , so that the direction of the reamer 2 can be adjusted by controlling the expansion and contraction of the second support rod 5 . Of course, it may also be that: the first support rod, the second support rod and the support rod are all telescopic rods with controllable lengths, so as to improve the flexibility of control and make the reamer control device more flexible in deformation.

Abstract

The invention provides an engineering ship and relates to an engineering ship. It solves the problem in the prior art that engineering ships are not conducive to working on the seabed in complex environments. The engineering ship includes a hull, a reamer, and a reamer control device. The reamer control device includes a reamer bracket, and the reamer bracket includes a first rack bar and a second rack bar parallel to each other. The upper end of the frame rod is rotatably connected to the reamer slider, the lower ends of the first frame rod and the second frame rod are rotatably connected to the reamer, and a support rod is also included, one end of the support rod is rotatably connected to the support slider, The other end of the support rod is connected to the support wheel. The invention can conveniently realize the flexible control of the ship and the reamer, and improve the adaptability to the seabed operation environment.

Description

technical field [0001] The invention belongs to the technical field of ships, in particular to an engineering ship. Background technique [0002] With the development of marine development, there is an increasing demand for various engineering ships, especially working ships capable of processing seabed sediment. For example, common dredgers, mining ships, and seabed trimming ships usually need to use reamers extending into the seabed to cut seabed sand or rock formations, and then use cutter suction pumps to transport the sand to ships or other sea areas. [0003] However, the seabed environment is complex, and the existing reamer control device is complex but has simple functions, which can only realize simple lowering or swinging, which is not conducive to working on the seabed in a complex environment; moreover, most of such ships need to use positioning piles to realize The control of the movement of the ship is extremely inconvenient for moving the ship.
