[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] Example 1, with reference to Figure 1-3 A hose crane with high stability comprises a shipboard fixing seat 1, a counterweight seat 2 welded to the top outer wall of the shipboard fixing seat 1, and a protective cover 3 fixedly connected to the top outer wall of the counterweight seat 2;

[0025] In this embodiment, a rotating arm 4 is rotatably installed in the protective cover 3, a boom 5 is hinged on the top of the rotating arm 4, a cylinder 6 is hinged between the rotating arm 4 and the boom 5, a wire rope 7 is connected to the boom 5 through a hoist, and a hose positioning seat 8 is welded to the bottom end of the wire rope 7. The automated lifting operation is achieved through the coordinated cooperation of the boom 5, the cylinder 6 and the wire rope 7 connected to the hoist.

[0026] In this embodiment, three hose clamping assemblies are provided on the hose positioning seat 8 at equal distances. The hose clamping assembly includes a slide 9 opened on one side of the hose positioning seat 8, a threaded vertical rod 10 rotatably mounted in the slide 9, a movable block 11 threadedly connected to the threaded vertical rod 10, two linkage oblique rods 14 symmetrically hinged to the movable block 11, two centering sliders 12 symmetrically arranged around the threaded vertical rod 10, and two arc-shaped clamping blocks 13 symmetrically fixed to the outer walls of the bottom of the two centering sliders 12. One end of the two linkage oblique rods 14 is respectively hinged to the top of the two centering sliders 12.

[0027] Furthermore, a guide transverse shaft 15 is fixedly connected to the hose positioning seat 8, and a guide sleeve 16 is fixedly embedded in each of the two centering sliders 12. The two guide sleeves 16 are slidably connected to the guide transverse shaft 15, so that the movement of the two centering sliders 12 can be guided to ensure the stability of their linear motion.

[0028] Furthermore, the outer walls of the adjacent sides of the two arc-shaped clamping blocks 13 are bonded with C-shaped rubber pads 17, which facilitates the protection of the hose head during the clamping process. The outer wall of the movable block 11 is slidably connected to the inner wall of the slide groove 9, which can ensure that the movable block 11 can move linearly. The top of the threaded vertical rod 10 is fixedly connected to the crank handle 18.

[0029] During the specific implementation of this embodiment: the threaded vertical rod 10 is controlled to rotate by the crank 18, and then under the limit of the slide groove 9, the movable block 11 threadedly connected to the threaded vertical rod 10 will move upward, and then under the hinge effect of the two linked oblique rods 14, the two centering sliders 12 will be centered and brought together on the guide horizontal axis 15, and then the two centering sliders 12 drive the two arc-shaped clamping blocks 13 to be centered and brought together, so as to clamp the hose heads of different specifications. Then, the three hose clamping assemblies can clamp the three hose heads of different specifications to replace the traditional method of lifting with hooks, thereby avoiding the situation where the hose falls off due to shaking, and effectively improving the stability during the lifting process.

[0030] Example 2, reference Figure 1 and Figure 4 This embodiment is optimized based on the first embodiment. Specifically, the protective cover 3 is provided with an azimuth adjustment mechanism, which includes a stepper motor 20 fixedly mounted on the side wall of the protective cover 3, a worm 21 fixedly mounted on the output shaft of the stepper motor 20, and a worm wheel 22 fixedly mounted on the lower part of the rotating arm 4 and meshing with the worm 21. The output shaft of the stepper motor 20 passes through one side of the protective cover 3, and the bottom end of the rotating arm 4 is connected to the top of the counterweight seat 2 via a slewing bearing 19.

[0031] During the specific implementation of this embodiment: the worm 21 is controlled to rotate by the stepping motor 20, and then the worm wheel 22 engaged with the worm 21 drives the rotating arm 4 to rotate, so that the lifting orientation can be flexibly adjusted, and the stability of the rotating movement of the rotating arm 4 can be ensured through the meshing transmission of the worm 21 and the worm wheel 22 and the connection effect of the slewing bearing 19.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
