Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of double-spoke plate pulley design for ship lifts, and in particular to a double-spoke plate rolled pulley for ship lifts. Background Technology
[0002] A ship lift is a navigation structure used for the vertical lifting and lowering of ships. It uses mechanical devices to raise or lower ships from one water level to another. It mainly consists of a ship-carrying chamber (equivalent to a large "elevator car" that can accommodate ships), a lifting mechanism, a lock, and a navigation channel. When a ship needs to be lifted from a lower water level to a higher water level, the ship first enters the ship-carrying chamber. Then, the ship-carrying chamber rises vertically under the action of the lifting mechanism. After reaching the higher water level, the ship-carrying chamber connects with the lock at the higher water level, and the ship exits the ship-carrying chamber and enters the navigation channel at the higher water level. Pulley blocks are used when lifting ships; existing pulley blocks are mostly double-spoke rolled plate pulleys.
[0003] The existing double-spoke pulley system causes the cable to become irregularly entangled on the pulley system during rotation and winding, resulting in errors in the height at which the cable lifts the ship. When multiple pulley systems work simultaneously, the ship is prone to tilting, affecting the stability of lifting the ship. Utility Model Content
[0004] In view of the problems existing in the double-spoke rolled pulleys used in the ship lift, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide a double-spoke rolled pulley for a ship lift, which aims to solve the technical problems of existing double-spoke pulley sets where the cable is irregularly wrapped around the pulley set during rotation and winding, the cable lifts the ship at an incorrect height, and the ship tends to tilt when multiple pulley sets work simultaneously, thus affecting the stability of the ship lift.
[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a base unit, including a support plate, a first bracket disposed on the support plate, a lead screw rotatably disposed on the top of the first bracket, and a motor disposed on the lead screw;
[0007] The transmission unit includes a second bracket disposed on the support plate, a sleeve disposed on the top of the second bracket, and a limiting groove formed in the inner wall of the sleeve;
[0008] The rotating unit includes a drive shaft mounted on the sleeve, a movable frame mounted on the drive shaft, a limiting key mounted on the drive shaft, and a wheel assembly mounted at one end of the drive shaft.
[0009] In a preferred embodiment of the double-spoke rolled pulley for the ship lift of this utility model, a guide rail is fixedly provided in the middle of the support plate, and the movable frame is slidably connected to the guide rail.
[0010] In a preferred embodiment of the double-spoke rolled pulley for the ship lift described in this utility model, the guide rail has a T-shaped cross-section.

[0012] In a preferred embodiment of the double-spoke rolled pulley for the ship lift described in this utility model, the motor is bolted to the first bracket.
[0013] In a preferred embodiment of the double-spoke rolled pulley for the ship lift described in this utility model, the limiting groove is square.
[0014] In a preferred embodiment of the double-spoke rolled pulley for the ship lift described in this utility model, the sleeve is connected to the bearing of the second support.
[0015] In a preferred embodiment of the double-spoke rolled pulley for the ship lift of this utility model, a first sprocket is provided outside the sleeve, a second sprocket is provided behind the first sprocket, and a chain is provided between the first sprocket and the second sprocket.

[0017] In a preferred embodiment of the double-spoke rolled pulley for the ship lift described in this utility model, the drive shaft and the limiting key are both slidably connected to the sleeve.
[0018] The beneficial effects of this utility model are: by setting a screw to drive the wheel group to move, the cable can be evenly wound on the wheel group during the rotation of the wheel group, preventing the cable on the wheel group from being messy, which would cause the cable of each group to be suspended in the air with inconsistent length, causing the hull to tilt and affecting the stability of lifting the ship.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention.

[0028] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model.

[0029] Example 1
[0030] Reference Figure 1-4 This is the first embodiment of the present invention, which provides a double-spoke plate rolled pulley for a ship lift. The device includes a base unit 1, including a support plate 101, a first bracket 103 disposed on the support plate 101, a lead screw 104 rotatably disposed on the top of the first bracket 103, and a motor 105 disposed on the lead screw 104, which facilitates the conversion of the rotational motion of the motor 105 into 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 formed in the inner wall of the sleeve 202.
[0032] The rotating unit 3 includes a drive shaft 302 mounted on the sleeve 202, a movable frame 301 mounted on the drive shaft 302, a limiting key 303 mounted on the drive shaft 302, and a wheel set 304 mounted at one end of the drive shaft 302. The limiting key 303 on the sleeve 202 and the limiting key 303 on the drive shaft 302 cooperate to realize the synchronous rotation of the drive shaft 302.
[0033] The support plate 101 has a guide rail 102 fixedly installed in the middle. The movable frame 301 is slidably connected to the guide rail 102. The guide rail 102 provides a fixed path, which allows the movable frame 301 to move precisely in a straight line along this path. This ensures the accurate positioning of the wheel set 304 during the lifting process and reduces friction of the movable frame 301 during movement, thereby reducing energy loss and component wear and extending the service life of the equipment.
[0034] The guide rail 102 has a T-shaped cross-section, which provides a larger base area, making the guide rail 102 more stable when supporting the moving frame 301, reducing deformation caused by load, and the T-shaped guide rail 102 has stronger load-bearing capacity and strong anti-torsional performance, which helps to maintain the straightness of the moving frame 301 during movement, reduce deviation, and improve the stability of the device. At the same time, the T-shaped cross-section can effectively prevent the accumulation of dirt and debris, making it easier for staff to clean.
[0035] During use, the operator turns on the motor 105 to drive the lead screw 104 to rotate, which in turn drives the sleeve 202 to rotate. Through the limit groove 203, the limit key 303 on the transmission shaft 302 rotates synchronously, so that the transmission shaft 302 drives the wheel set 304 to rotate, thereby realizing the winding and unwinding of the cable and controlling the lifting of the ship lift. The rotation of the lead screw 104 can drive the moving frame 301 to move along the guide rail 102 on the support plate 101, so as to realize the uniform translation of the wheel set 304 and ensure that the cable is evenly wound on the wheel set 304.
[0036] Example 2
[0037] Reference Figure 1-4 This is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the first bracket 103 is welded together with 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. This fixes the position of the first bracket 103 on the support plate 101, reduces displacement caused by vibration or impact, and improves the stability and durability of the entire device.
[0038] Compared to Embodiment 1, the motor 105 is further bolted to the first bracket 103. This connection method makes it easier for workers to quickly and conveniently install and replace the motor 105, improving work efficiency. Moreover, the position and angle of the motor 105 can be adjusted at will to adapt to different installation requirements, thus improving the adaptability of the device.
[0039] Compared to Embodiment 1, the limiting groove 203 is square with four distinct edges, which can more accurately position the drive shaft 302 or moving parts, improving the positioning accuracy. The square geometry also gives it higher structural strength. At the same time, its larger contact area and uniform pressure distribution can effectively reduce local wear and provide a more reliable limiting effect, reducing the risk of parts displacement due to external forces. It is more competitive in terms of economic benefits and safety performance.
[0040] Compared to Embodiment 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 service life. The bearing connection makes the rotational movement of the sleeve 202 more stable and precise, effectively improving the synchronization and accuracy of the entire transmission system.
[0041] The remaining structure is the same as that in Example 1.
[0042] Example 3
[0043] Reference Figure 1-4 This is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: a first sprocket 204 is provided outside the sleeve 202, and a second sprocket 205 is provided behind the first sprocket 204. A chain 206 is provided between the first sprocket 204 and the second sprocket 205. The chain 206 connects the first sprocket 204 and the second sprocket 205 and transmits 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 overall accuracy of the device and reduces the workload of the workers.
[0044] Compared to Embodiment 2, the second sprocket 205 is further connected to the lead screw 104 by a key, which ensures the synchronous movement between the second sprocket 205 and the lead screw 104. The structure is simple and avoids the use of too much redundant design, thereby improving the working efficiency of the device.
[0045] Compared to Embodiment 2, the transmission shaft 302 and the limiting key 303 are further slidably connected to the sleeve 202, allowing the transmission shaft 302 to move freely within the sleeve 202, which is convenient for adapting to different working scenarios. At the same time, it can prevent the transmission shaft 302 from moving excessively or deviating from the predetermined path. Moreover, this connection method makes the transmission shaft 302 and the limiting key 303 easy to replace, which can reduce the labor intensity of the workers and reduce maintenance costs.
[0046] The remaining structure is the same as that in Example 2.
