Description

Technical Field

[0001] This application relates to the technical field of hoisting devices, and in particular to a hoisting device for docks. Background Technology

[0002] In industrial production, logistics and warehousing, and other fields, cargo lifting is a core process, and equipment such as gantry cranes are widely used for the transfer of light and heavy goods. The traditional structure includes a frame, rope winding assembly (motor, reducer, rope drum), lifting rope, hook, and simple angle adjustment components (such as a single hydraulic rod), and the operation is completed by winding and unwinding the rope and fine-tuning the angle. The existing dock hoisting equipment has non-adjustable pulley spacing and fixed positioning pulleys, making it difficult to adapt to goods of different sizes. Wide goods are prone to tipping over, and small goods are prone to swaying. As a result, when hoisting different items, it is often necessary to purchase additional equipment, increasing costs and occupying space. Utility Model Content

[0003] To address the problem that the pulley spacing of existing dock hoisting equipment cannot be adjusted, this application provides a dock hoisting device.

[0004] The technical solution of the hoisting device for docks provided in this application is as follows: A hoisting device for a dock includes a tower body, on which a support beam is fixedly installed. A stabilizing tilting frame is installed at the head of the support beam and is rotatably connected to the support beam. A control component for driving the stabilizing tilting frame to rotate is also installed on the tower body. A reinforcing member is fixedly installed on the stabilizing tilting frame, and a transverse shell is fixedly installed at the lower end of the stabilizing tilting frame. Two sets of positioning pulleys are installed in the transverse shell and are slidably connected to the transverse shell. A driving component for adjusting the distance between the two sets of positioning pulleys is also installed on the transverse shell. A hoisting rope is installed on the stabilizing tilting frame, and a hook is suspended from the hoisting rope. A rope winding assembly for winding the hoisting rope is also installed on the tower body.

[0005] By adopting the above technical solution, support beams and a stabilizing tilting frame are installed on the tower body. The stabilizing tilting frame is driven to rotate using control components, allowing adjustment of the lifting angle to adapt to different lifting scenarios. Reinforcing members on the stabilizing tilting frame enhance structural stability. The sliding positioning pulleys in the transverse shell, in conjunction with the adjustable spacing of the drive components, allow for adjustment of the lifting positioning point according to the cargo size, improving lifting flexibility. Lifting ropes and hooks are used to lift cargo, and the rope reel assembly facilitates the raising and lowering of the ropes.

[0006] Optionally, the control component includes a guide frame and a hydraulic cylinder. The head of the guide frame is rotatably connected to the stabilizing tilting frame, the tail of the hydraulic cylinder is rotatably connected to the tower body, and the head of the hydraulic cylinder is rotatably connected to the lower end of the guide frame.

[0007] By adopting the above technical solution, the control component uses a combination of guide frame and hydraulic cylinder. The extension and retraction of the hydraulic cylinder drives the rotation of the stable tilting frame through the guide frame, which can accurately control the rotation angle of the stable tilting frame and make the hoisting process more stable.

[0008] Optionally, the transverse shell includes a main frame shell and a motor mount, the motor mount being mounted on the outer side of the main frame shell and fixedly connected to the main frame shell.

[0009] By adopting the above technical solution, the transverse shell is divided into a main frame shell and a motor mount. The motor mount is used to install components such as the drive motor. Separating the motor from the main frame shell facilitates maintenance and repair, and also avoids the impact of vibration generated during motor operation on the internal structure of the main frame shell.

[0010] Optionally, the main frame includes a concave shell and a positioning slide rod for mounting the positioning pulley. The positioning slide rod is installed in the concave shell, and both ends of the positioning slide rod are fixedly installed on the inner side of the concave shell. An auxiliary slide rod is also fixedly installed in the concave shell.

[0011] By adopting the above technical solution, the concave shell in the main frame provides installation space for the positioning pulley, the positioning slide rod ensures the sliding trajectory of the positioning pulley, and the auxiliary slide rod plays a supporting and guiding role, making the sliding of the positioning pulley more stable and improving the reliability of the hoisting device.

[0012] Optionally, an arc-shaped baffle is installed on the outer side of the concave shell to block the suspension rope on the positioning pulley, and the two ends of the arc-shaped baffle are fixedly connected to the concave shell.

[0013] By adopting the above technical solution, the arc-shaped baffle on the outer side of the concave shell can block the lifting rope on the positioning pulley, preventing the lifting rope from detaching from the positioning pulley, and also improving the safety of the lifting process.

[0014] Optionally, the positioning pulley includes a central tube and side baffles, the side baffles being installed at both ends of the central tube and fixedly connected to the central tube.

[0015] By adopting the above technical solution, the central tube of the positioning pulley is used to hang the lifting rope, and the side baffles are installed at both ends of the central tube to prevent the lifting rope from slipping off the pulley, thus ensuring the stable operation of the lifting rope on the pulley and improving the safety of the hoisting.

[0016] Optionally, the driving component includes a main drive assembly and two sets of levers corresponding to the positioning pulley. The levers are slidably mounted on the auxiliary slide rod, and the main drive assembly is used to adjust the distance between the two sets of levers.

[0017] By adopting the above technical solution, the driving component adopts a combination of main drive assembly and paddle block. The paddle block is slidably installed on the auxiliary slide rod and installed between the two sets of side baffles of the positioning pulley, which facilitates the synchronous movement of the positioning pulley. The main drive assembly adjusts the spacing of the paddle block, thereby driving the positioning pulley to slide, realizing the precise adjustment of the spacing of the positioning pulley to adapt to the hoisting needs of goods of different sizes.

[0018] Optionally, the main drive assembly includes a drive motor and a double-ended screw. The double-ended screw passes through a dial block and is threadedly connected to the dial block. The drive motor is fixedly mounted on a motor base, and the output end of the drive motor is fixedly connected to one end of the double-ended screw.

[0019] By adopting the above technical solution, the drive motor in the main drive assembly drives the double-ended screw to rotate. Since the double-ended screw is threadedly connected to the levers, the rotation of the double-ended screw can cause the two sets of levers to move towards or away from each other, thereby adjusting the spacing of the positioning pulleys. This method offers high transmission efficiency and enables quick and accurate adjustment of the positioning pulley positions.

[0020] In summary, this application includes at least one of the following beneficial technical effects: By setting up a stable tilting frame and precisely controlling its rotation through control components, the lifting process becomes smoother. Reinforcing members enhance the structural strength of the stable tilting frame, arc-shaped baffles protect the lifting ropes, and side baffles on the positioning pulleys prevent the lifting ropes from slipping, all of which improve the overall stability of the lifting device. Simultaneously, the distance between the two sets of positioning pulleys can be easily adjusted through the drive mechanism, adapting to the lifting needs of goods of different sizes and improving work efficiency. Furthermore, the stable tilting frame is rotatable, allowing for adjustment of the lifting angle to adapt to different lifting scenarios. Attached Figure Description

[0027] The present application will be further described in detail below with reference to the accompanying drawings.

[0028] This application discloses a hoisting device for a dock. (Refer to...) Figure 1 , Figure 2 and Figure 3 A hoisting device for docks includes a tower body 1, a support beam 2 fixedly mounted on the tower body 1, a stabilizing tilting frame 3 mounted at the head of the support beam 2, the stabilizing tilting frame 3 being rotatably connected to the support beam 2, and a control component 4 for driving the rotation of the stabilizing tilting frame 3 mounted on the tower body 1. A reinforcing member is fixedly mounted on the stabilizing tilting frame 3, and a transverse shell 5 is fixedly mounted at the lower end of the stabilizing tilting frame 3. Two sets of positioning pulleys 6 are installed in the transverse shell 5, slidably connected to the transverse shell 5, and a driving component 7 for adjusting the distance between the two sets of positioning pulleys 6 is mounted on the transverse shell 5. A hoisting rope 8 is mounted on the stabilizing tilting frame 3, with a hook 9 suspended from the hoisting rope 8, and a rope winding assembly for winding the hoisting rope 8 is also mounted on the tower body 1. By setting the support beam 2 and the stabilizing tilting frame 3 on the tower body 1, and using the control component 4 to drive the rotation of the stabilizing tilting frame 3, the hoisting angle can be adjusted to adapt to different hoisting scenarios. The reinforcing member on the stabilizing tilting frame 3 enhances the structural stability. The positioning pulleys 6 in the transverse shell 5 are slidable and their spacing can be adjusted in conjunction with the drive component 7, allowing the lifting positioning point to be adjusted according to the size of the goods, thus improving the flexibility of lifting. The lifting rope 8 and hook 9 are used to lift the goods, and the rope winding assembly facilitates the winding and unwinding of the lifting rope 8, realizing the lifting and lowering of the goods.

[0029] Reference Figure 1 The control component 4 includes a guide frame 41 and a hydraulic cylinder 42. The head of the guide frame 41 is rotatably connected to the stabilizing tilting frame 3, and the tail of the hydraulic cylinder 42 is rotatably connected to the tower body 1. The head of the hydraulic cylinder 42 is rotatably connected to the lower end of the guide frame 41. The control component 4 adopts a combination of the guide frame 41 and the hydraulic cylinder 42. The extension and retraction of the hydraulic cylinder 42 drives the stabilizing tilting frame 3 to rotate through the guide frame 41. This structure is simple and reliable, and can accurately control the rotation angle of the stabilizing tilting frame 3, making the hoisting process more stable.

[0030] Reference Figure 3 , Figure 4 and Figure 5The transverse shell 5 includes a main frame shell 51 and a motor base 52. The motor base 52 is installed on the outer side of the main frame shell 51 and is fixedly connected to the main frame shell 51. The transverse shell 5 is divided into the main frame shell 51 and the motor base 52. The motor base 52 is used to install components such as the drive motor 711, separating the motor from the main frame shell 51 for easy maintenance and repair, and also avoiding the impact of vibration generated during motor operation on the internal structure of the main frame shell 51. The main frame shell 51 includes a concave shell 511 and a positioning slide rod 512 for mounting the positioning pulley 6. The positioning slide rod 512 is installed in the concave shell 511, and both ends of the positioning slide rod 512 are fixedly installed on the inner side of the concave shell 511. An auxiliary slide rod 510 is also fixedly installed in the concave shell 511. The concave shell 511 in the main frame 51 provides installation space for the positioning pulley 6. The positioning slide rod 512 ensures the sliding trajectory of the positioning pulley 6, while the auxiliary slide rod 510 provides auxiliary support and guidance, making the sliding of the positioning pulley 6 more stable and improving the reliability of the hoisting device. An arc-shaped baffle 513 is installed on the outer surface of the concave shell 511 to block the hoisting rope 8 on the positioning pulley 6. The two ends of the arc-shaped baffle 513 are fixedly connected to the concave shell 511. The arc-shaped baffle 513 on the outer side of the concave shell 511 can block the hoisting rope 8 on the positioning pulley 6, preventing the hoisting rope 8 from detaching from the positioning pulley 6, and also improving the safety of the hoisting process.

[0031] Reference Figure 2 , Figure 3 and Figure 5 The positioning pulley 6 includes a central tube 61 and side baffles 62. The side baffles 62 are installed at both ends of the central tube 61 and are fixedly connected to the central tube 61. The central tube 61 of the positioning pulley 6 is used to hang the lifting rope 8, and the side baffles 62 installed at both ends of the central tube 61 can prevent the lifting rope 8 from slipping off the pulley, ensuring the stable operation of the lifting rope 8 on the pulley and improving the safety of lifting.

[0032] Reference Figure 2 , Figure 3 and Figure 4The driving component 7 includes a main drive assembly 71 and two sets of levers 72 corresponding to the positioning pulley 6. The levers 72 are slidably mounted on the auxiliary slide rod 510. The main drive assembly 71 is used to adjust the distance between the two sets of levers 72. The driving component 7 adopts a combination of the main drive assembly 71 and the levers 72. The levers 72 are slidably mounted on the auxiliary slide rod 510 and are installed between the two sets of side baffles 62 of the positioning pulley 6, which facilitates the synchronous movement of the positioning pulley 6. The main drive assembly 71 adjusts the distance between the levers 72, thereby driving the positioning pulley 6 to slide, realizing precise adjustment of the distance between the positioning pulley 6 to adapt to the lifting requirements of goods of different sizes. The main drive assembly 71 includes a drive motor 711 and a double-ended screw 712. The double-ended screw 712 passes through the levers 72 and is threadedly connected to the levers 72. The drive motor 711 is fixedly mounted on the motor base 52, and the output end of the drive motor 711 is fixedly connected to one end of the double-ended screw 712. The drive motor 711 in the main drive assembly 71 drives the double-ended screw 712 to rotate. Since the double-ended screw 712 is threadedly connected to the lever 72, the rotation of the double-ended screw 712 can cause the two sets of levers 72 to move towards or away from each other, thereby adjusting the spacing of the positioning pulleys 6. This drive method has a simple structure, high transmission efficiency, and can quickly and accurately adjust the position of the positioning pulleys 6.

[0033] The implementation principle of a dock lifting device according to an embodiment of this application is as follows: In actual use, the drive motor 711 can be started according to the size of the cargo. The drive motor 711 drives the double-headed screw 712 to rotate, causing the two sets of levers 72 to move towards or away from each other, thereby adjusting the distance between the two sets of positioning pulleys 6 to meet the lifting requirements of the cargo. The hydraulic cylinder 42 is started, and the extension and retraction of the hydraulic cylinder 42 drives the stabilizing tilting frame 3 to rotate through the guide frame 41, adjusting the lifting angle so that the hook 9 is aligned with the cargo. The motor of the rope winding assembly is started, which drives the rope drum to rotate through the reducer, lowering the lifting rope 8 and causing the hook 9 to descend above the cargo. The hook 9 is hung on the cargo, and then the motor of the rope winding assembly is started to wind up the lifting rope 8, lifting the cargo. After the cargo is lifted to the designated position, the lifting rope 8 is lowered, and the hook 9 is removed, completing one lifting operation.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
