[0006] In order to solve the above technical problems, the utility model provides a hoist with good water utilization stability, including a boom, a movable rod and a bracket. The lower part of the bracket is in an I-shape, and has a certain curvature at its bottom. At the same time, a through hole is opened on one side of the bracket, a screw is fixed at the through hole, and a fixing clamp is arranged on the other side of the screw.

[0007] Preferably, grooves are provided on the inner sides of the booms on both sides, rotating rods are provided in the grooves, the rotating rods pass through one side of the booms and a first motor is provided outside the outside, and a slider is sleeved on the rotating rod, a moving rod is fixed on one side of the slider, and a through groove is provided above the moving rod.

[0009] Preferably, the two second motors are arranged opposite to each other, and the rotation directions of the two second motors are consistent.

[0010] Preferably, a window is provided between the boom and the bracket.

[0011] Preferably, the fixing clip is made of rubber.

[0012] The utility model provides a hoist with good water utilization stability. It has the following beneficial effects:

[0013] (1) This kind of crane has good water utilization stability. During use, the design of the fixing clamp greatly improves the adaptability of the device to various ship hulls. It has a higher degree of application in water conservancy and can enable ships to lift and transport cargo from each other during operation, facilitating various lifting needs in daily use.

[0014] (2) The water-utilizing crane has good stability. During use, the dual-setting power components make the overall device more stable and steady during operation. It is more stable in weather conditions such as strong winds, thereby ensuring the safety of the device operation.

[0015] (3) This type of crane has good water utilization stability. During use, the dual-set steel cable power system enables the device to have a higher upper limit on the weight of the cargo it can retrieve, and the retrieval and transportation process is smoother and safer, greatly improving the overall practicality of the device.

[0021] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of the utility model of a hoist with good water utilization stability in conjunction with the accompanying drawings.

[0022] like Figure 1 - Figure 4 As shown, a first embodiment of the utility model is a crane with good water utilization stability, including a boom 1, a movable rod 2 and a bracket 5. The lower part of the bracket 5 is in an I-shape, and its bottom has a certain curvature. At the same time, a through hole is opened on one side of the bracket 5, and a screw 7 is fixed at the through hole. A fixing clamp 6 is arranged on the other side of the screw 7. The arrangement of the fixing clamp 6 greatly reduces the restriction of the device on the difference of the hull. The fixing clamp 6 can better fit the hull railings of various sizes through the adjustment of the screw 7, and the arc design arranged at its bottom can make the device better fix the hull, thereby ensuring the stable and smooth operation of the device.

[0023] Grooves are provided on the inner sides of the booms 1 on both sides, and rotating rods 3 are provided in the grooves. The rotating rod 3 passes through one side of the boom 1 and a first motor 4 is provided outside the rotating rod 3. At the same time, a slider 11 is sleeved on the rotating rod 3, and a moving rod 2 is fixed on one side of the slider 11. A through groove 12 is provided above the moving rod 2. The cooperation between the slider 11 and the moving rod 2 makes the moving part of the device move more freely, and the two movable structures arranged inside the boom 1 make the device run more smoothly and safely.

[0024] Two second motors 8 are arranged on both sides of the top of the moving rod 2, a transmission rod 13 is arranged on one side of the transmission shaft of the two second motors 8, a winch 14 is arranged in the middle position of the two transmission rods 13, a steel cable 9 is arranged in the winch 14, and a hook 10 is arranged under the steel cable 9. The winch 14 connected by the two motors can fix and transport the goods more smoothly, ensuring the stability of the lifting and transportation process. The setting of the transmission rod 13 enables the device to better transmit power.

[0025] The two second motors 8 are arranged opposite to each other, and the rotation directions of the two second motors 8 are consistent. Such a design can make the steel cable 9 part of the device have more powerful power and smoother power output, ensuring the safety and stability of the goods during the process of lifting the goods.

[0026] A window is provided between the boom 1 and the bracket 5, and the window is used to facilitate hanging or taking of goods on the hook 10, thereby improving the practicability of the device.

[0027] The fixing clamp 6 is made of rubber material. The use of rubber material enables the device to adapt to all railing parts of the hull during use, thereby limiting and fixing the position of the device.

[0028] In summary, when the utility model is in use, first, the railing is inserted into the groove opened under the bracket 5 of the device, and then the tightness of the fixing clamp 6 is adjusted by the screw 7 to lock the railing, and then the first motor 4 and the second motor 8 are used to control the movement of the moving rod 2, and the hook 10 is pulled to the required shore or ship through the steel cable 9, and then the cargo to be lifted is hung on the hook 10, and then the cargo is transported by the second motor 8 and the first motor 4.
