[0022] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figures 1-5 In this embodiment of the utility model, a hydraulic lifting beam device with a pulley includes a crossbeam 1. Two track grooves 2 are formed on the outer surface of the crossbeam 1. The interior of each track groove 2 is rotatably connected to a traveling wheel 3. A first bearing 4 is embedded on the side of each set of traveling wheels 3 that is far apart from each other. A connecting rod 5 is installed on the inner ring of each first bearing 4. A support rod 6 is installed on the outer surface of each connecting rod 5. A working box 7 is installed at one end of the two sets of support rods 6. The overall device has the advantages of convenient mobility, lifting stability and structural durability. It is suitable for a variety of lifting scenarios and can effectively improve work efficiency and safety.

[0025] The inner wall of the working box 7 is inlaid with symmetrical second bearings 8. The inner rings of the two second bearings 8 are jointly installed with take-up and release rollers 9. The outer surface of the take-up and release rollers 9 is wound with steel cables 18. The steel cables 18 are made by hinged multiple steel wires. Two protective plates 10 are installed on the outer surface of the take-up and release rollers 9. Protective pads 11 are installed on the side of the two protective plates 10 that are close to each other. The back of the working box 7 is equipped with a first hydraulic motor 16. The output end of the first hydraulic motor 16 is connected to the take-up and release rollers 9 through a coupling. This not only facilitates the hoisting of the target, but also protects the steel cables 18 and prevents wear on the outer surface of the steel cables 18.

[0026] A rack 13 is mounted on the bottom surface of the crossbeam 1, a fixing block 15 is mounted on the upper surface of the work box 7, a second hydraulic motor 12 is mounted on the upper surface of the fixing block 15, and a gear 17 is mounted on the output end of the second hydraulic motor 12 through a coupling. The gear 17 meshes with the rack 13. A strip-shaped opening 14 is opened on the bottom surface of the work box 7, and the gear 17 meshes with the rack 13. This not only makes it convenient for people to control the movement of the equipment, but also greatly increases the stability of the equipment, thus making the operation of the equipment more stable.

[0027] The working principle of this utility model is as follows: First, the second hydraulic motor 12 starts, and its output end drives the gear 17 to rotate through the coupling. Since the gear 17 meshes with the rack 13 on the bottom surface of the crossbeam 1, it drives the working box 7 to move along the crossbeam 1. The traveling wheel 3 rolls in the track groove 2. The first bearing 4, connecting rod 5, and support rod 6 ensure the smoothness of movement. After reaching the designated position, the first hydraulic motor 16 starts, driving the take-up and release roller 9 to rotate through the coupling. The steel cable 18 wound on the outer surface of the take-up and release roller 9 begins to be taken up and released, realizing the lifting and lowering of heavy objects. The take-up and release roller 9 is supported by the second bearing 8 on the inner wall of the working box 7, and rotates flexibly. The protective plate 10 and the protective pad 11 can prevent the steel cable 18 from detaching or abrading. The steel cable 18 is made of multiple steel wires hinged together to prevent the steel cable 18 from breaking.
