Description

Technical Field

[0001] The invention relates to the technical field of double-spoke plate pulley design for a ship lift, in particular to a double-spoke plate rolled pulley for a ship lift. Background Art

[0002] A ship lift is a navigation structure used for the vertical lifting of ships. The ship lift uses mechanical devices to lift or lower ships from one water level to another. It is mainly composed of a ship-carrying compartment (equivalent to a large "elevator car" that can accommodate ships), a lifting mechanism, a lock head, a pilot channel, and other parts. When a ship is to be lifted from a low water level to a high water level, the ship first enters the ship-carrying compartment, and then the ship-carrying compartment rises vertically under the action of the lifting mechanism. After reaching the high water level, the ship-carrying compartment docks with the lock head at the high water level, and the ship sails out of the ship-carrying compartment and enters the high water level channel. When lifting a ship, a pulley block is required, and the existing pulley blocks are mostly double-spoke plate rolled pulleys.

[0003] In the existing double-spoke pulley block, the cable is irregularly wound around the wheel block during the rotating and winding process, and there is an error in the height of the ship lifted by the cable. When multiple sets of wheel blocks work at the same time, the hull is easily tilted, affecting the stability of the ship lift. Summary of the invention

[0004] In view of the above-mentioned problems existing in the conventional double-spoke plate rolled pulley for ship lift, the present invention is proposed.

[0005] Therefore, the purpose of the present invention is to provide a double-spoke rolled pulley for a ship lift, which aims to solve the technical problems that the cable is irregularly wound around the wheel group during the rotation and wire collection process of the existing double-spoke pulley group, there is an error in the height of the ship lifted by the cable, and the hull is easily tilted when multiple sets of wheels work at the same time, affecting the stability of the ship lift.

[0008] The rotating unit comprises a transmission shaft arranged on the sleeve, a moving frame arranged on the transmission shaft, a limit key arranged on the transmission shaft, and a wheel set arranged at one end of the transmission shaft.

[0009] As a preferred solution of the double-spoke plate rolled pulley for the ship lift described in the present invention, a guide rail is fixedly arranged in the middle of the support plate, and the movable frame is slidably connected to the guide rail.

[0010] As a preferred solution of the double-spoke plate rolled pulley for the ship lift described in the present invention, the cross section of the guide rail is T-shaped.

[0011] As a preferred solution of the double-spoke plate rolled pulley for the ship lift of the present invention, the first bracket is welded to the support plate.

[0012] As a preferred solution of the double-spoke rolled pulley for the ship lift of the present invention, the motor is bolted to the first bracket.

[0013] As a preferred solution of the double-spoke plate rolled pulley for the ship lift described in the present invention, the limiting groove is square.

[0014] As a preferred solution of the double-spoke plate rolled pulley for the ship lift of the present invention, the sleeve is connected to the second bracket bearing.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0028] Secondly, the present invention is described in detail with reference to the schematic diagram. When describing the embodiments of the present invention in detail, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention. In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0029] Example 1

[0030] Reference Figure 1-4 , which is the first embodiment of the present invention, provides a double-spoke plate rolled pulley for a ship lift, the device comprising a base unit 1, including a support plate 101, a first bracket 103 arranged on the support plate 101, a lead screw 104 rotatably arranged on the top of the first bracket 103, and a motor 105 arranged on the lead screw 104, so as to convert the rotational motion of the motor 105 into a linear motion;

[0031] The transmission unit 2 includes a second bracket 201 disposed on the support plate 101, a sleeve 202 disposed on the top of the second bracket 201, and a limiting groove 203 opened on the inner wall of the sleeve 202;

[0032] The rotating unit 3 includes a transmission shaft 302 arranged on the sleeve 202, a movable frame 301 arranged on the transmission shaft 302, a limit key 303 arranged on the transmission shaft 302, and a wheel set 304 arranged at one end of the transmission shaft 302. The sleeve 202 sleeve rod limit key 303 and the limit key 303 on the transmission shaft 302 cooperate to realize the synchronous rotation of the transmission shaft 302.

[0033] Among them, a guide rail 102 is fixedly set in the middle of the support plate 101, and the movable frame 301 is slidably connected to the guide rail 102. The guide rail 102 provides a fixed path, so that the movable frame 301 can accurately move in a straight line along this path, thereby ensuring the precise positioning of the wheel group 304 during the ship lifting process, and reducing the friction of the movable frame 301 during the movement, thereby reducing energy loss and component wear, and extending the service life of the equipment.

[0034] Among them, the cross-section of the guide rail 102 is T-shaped, and the T-shaped cross-section provides a larger bottom area, so that the guide rail 102 is more stable when supporting the mobile frame 301, reducing deformation caused by the load, and the T-shaped guide rail 102 has a stronger load-bearing capacity and strong torsion resistance, which helps to maintain the linearity of the mobile frame 301 during movement, reduce deviation, and improve the stability of the device. At the same time, the T-shaped cross-sectional shape can effectively avoid the accumulation of dirt and debris, making it easier for staff to clean.

[0035] During use, the staff turns on the motor 105 to drive the screw 104 to rotate, so that the screw 104 drives the sleeve 202 to rotate, and drives the limit key 303 on the transmission shaft 302 to rotate synchronously through the limit slot 203, so that the transmission shaft 302 drives the wheel group 304 to rotate, thereby realizing the winding and releasing of the cable and controlling the lifting of the ship lift. The rotation of the screw 104 can drive the moving frame 301 to move along the guide rail 102 on the support plate 101, realize the uniform translation of the wheel group 304, and ensure that the cable is evenly wound around the wheel group 304.

[0036] Example 2

[0037] Reference Figure 1-4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the first bracket 103 is welded to the support plate 101. This rigid connection improves the structural strength, thereby ensuring that the connection between the first bracket 103 and the support plate 101 is firm and reliable, and can withstand greater force and torque, so that the position of the first bracket 103 on the support plate 101 is fixed, reducing displacement caused by vibration or impact, and improving the stability and durability of the entire device.

[0038] Compared with Example 1, further, the motor 105 is bolted to the first bracket 103. This connection method makes it easy for the staff to quickly and conveniently install and replace the motor 105, thereby improving work efficiency. The position and angle of the motor 105 can also be adjusted at will to meet different installation requirements, thereby improving the adaptability of the device.

[0039] Compared with Example 1, the limiting groove 203 is square and has four clear edges, which can more accurately position the transmission shaft 302 or moving parts and improve the accuracy of positioning. The square geometric characteristics give it higher structural strength and a larger contact area, uniform pressure distribution, which can effectively reduce local wear and tear. It can also provide a more reliable limiting effect and reduce the risk of component displacement due to external force, making it more competitive in terms of economic benefits and safety performance.

[0040] Compared with Example 1, the sleeve 202 is connected to the second bracket 201 by a bearing, which can significantly reduce the rotational friction of the sleeve 202 on the second bracket 201, thereby reducing energy consumption and extending the service life. The bearing connection makes the rotational movement of the sleeve 202 smoother and more precise, effectively improving the synchronization and accuracy of the entire transmission system.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3

[0043] Reference Figure 1-4 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that a first sprocket 204 is arranged outside the sleeve 202, a second sprocket 205 is arranged behind the first sprocket 204, a chain 206 is arranged between the first sprocket 204 and the second sprocket 205, and the chain 206 connects the first sprocket 204 and the second sprocket 205 to transmit the power of the motor 105. Even if there is a certain degree of axial or angular deviation between the two sprockets, it does not affect the accuracy of the overall operation of the device, thereby reducing the work intensity of the staff.

[0044] Compared with Example 2, further, the second sprocket 205 is connected to the screw 104 by a flat key, which ensures the synchronous movement between the second sprocket 205 and the screw 104, and has a simple structure, avoiding the use of excessive redundant designs, thereby improving the workmanship efficiency of the device.

[0045] Compared with Example 2, further, the transmission shaft 302 and the limit key 303 are both slidably connected to the sleeve 202, so that the transmission shaft 302 can move freely in the sleeve 202, which is convenient for adapting to different working scenarios, and at the same time can prevent the transmission shaft 302 from excessive movement or deviation from the predetermined path. This connection method makes it easy to replace the transmission shaft 302 and the limit key 303, which can reduce the labor intensity of the staff and reduce maintenance costs.

[0046] The remaining structure is the same as that of Example 2.
