[0031] The floating pier comprises a pontoon 1, a drawbridge 2 and a hose 3, the pontoon 1 and the drawbridge 2 are respectively provided with fixed pipes 4, and the two ends of the hose 3 are connected with the fixed pipes 4, since the pontoon 1 is parked in the inland river, the pontoon 1 will be raised and lowered with the change of water level, tide or wave or the change of draft of the pontoon 1, so the pontoon 1 and the drawbridge 2 are both movable in the use process.

[0032] Please refer to Figures 1 to 5 The embodiment provides a movable hose bracket of a floating pier, the movable hose bracket comprises a lifting bracket 5 and a carrying trolley 6, the lifting bracket 5 is fixed on the carrying trolley 6, the pipe body of the hose 3 is overlapped on the lifting bracket 5, the other end of the carrying trolley 6 is connected with the drawbridge 2, and the carrying trolley 6 is movably connected to the deck of the pontoon 1. When the pontoon 1 is raised and lowered, the drawbridge 2 fixed on the carrying trolley 6 will push the carrying trolley 6 to move back and forth on the deck, so that the lifting bracket 5 moves back and forth along the hose 3, the contact area between the lifting bracket 5 and the hose 3 is different at different water levels, the range of the contact area is expanded, the stress area of the hose 3 is dispersed, the stress is avoided from being always concentrated in a small area, and meanwhile, the hose 3 is avoided from being repeatedly bent in a small area, so that the risk of abrasion and rupture of the hose 3 is finally reduced.

[0033] In this embodiment, the lifting bracket 5 specifically includes a frame, a lifting device 55, an axle 53, and a supporting wheel 54. The frame is fixed to the carrying trolley 6. The lifting device 55 includes a fixed end and a lifting end. The fixed end is fixedly connected with the frame. The axle 53 is connected with the lifting end. The supporting wheel 54 is rotatably connected with the axle 53. The hose 3 is overlapped with the supporting wheel 54. Since the lifting bracket 5 moves with the carrying trolley 6, the supporting wheel 54 supports the hose 3 to increase the contact area, avoid rigid friction between the hose 3 and the axle 53, make the lifting bracket 5 move more conveniently, effectively reduce the risk of damage of the hose 3 due to excessive friction and stress, further prolong the service life and maintenance period of the hose 3.

[0034] In an embodiment, preferably, the frame includes an outer frame 51 and an inner frame 52. The outer frame 51 is fixed to the carrying trolley 6. The fixed end is fixedly connected with the outer frame 51. The inner frame 52 is suspended on the lifting end. The axle 53 is fixedly connected with the inner frame 52. The outer frame 51 is connected with the carrying trolley 6 and moves with the carrying trolley 6.

[0035] In this embodiment, further preferably, the axial direction of the hose 3 is regarded as the front-rear direction. The limiting wheels are fixed on the inner frame 52 in left-right symmetry. The limiting wheels include a first limiting wheel 57 and a second limiting wheel 56. The side of the outer frame 51 facing the inner frame 52 is provided with a guide groove 58. The first limiting wheel 57 abuts against the groove bottom of the guide groove 58. The second limiting wheel 56 abuts against the front-rear side wall of the guide groove 58. The first limiting wheel 57 is mainly used for left-right limiting of the inner frame 52 to prevent the inner frame 52 from shaking left and right during lifting. The second limiting wheel 56 is mainly used for front-rear limiting of the inner frame 52 to prevent the inner frame 52 from moving front and back during front-rear movement of the lifting bracket 5, so that the lifting bracket 5 is more stable.

[0036] In an embodiment, the axle 53 is a front-rear parallel and upper-lower parallel axle 53. The axle 53 is connected with the inner frame 52.
