Abstract
Description
Lifting machines, easy-to-clean lifting mechanisms, and their working methods Technical Field
[0001] This invention belongs to the field of container hoisting technology, specifically relating to a device for hoisting and tilting containers, and more particularly to a hoisting machine, a hoisting mechanism that is easy to clean, and its working method. Background Technology
[0002] In the fields of ports, logistics, and industrial production, it is often necessary to use hoisting equipment to unload bulk materials from containers.
[0003] In related technologies, the hinged parts of hoisting mechanisms (such as the connection between the hinge and the hinge arm) are prone to accumulating debris, dirt, and other impurities during long-term use. This is especially true when dumping bulk materials, where dust or particles can easily penetrate the gaps at the hinge. Long-term accumulation leads to accelerated wear at the hinge, affecting the equipment's flexibility and service life. Furthermore, cleaning and maintenance often require disassembling the hinge components, a tedious and time-consuming process, and frequent disassembly may further accelerate component wear. Additionally, if the gaps are reduced to minimize debris and dirt accumulation, lubricating oil may not be able to reach the bearings of the hinge arm during subsequent lubrication.
[0004] Therefore, how to reduce the accumulation of impurities in the gap at the hinge without affecting the injection of lubricating oil is a technical problem that urgently needs to be solved.
[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Summary of the Invention
[0006] This disclosure provides at least one hoisting machine, a hoisting mechanism that is easy to clean, and a method for operating the same.
[0007] In a first aspect, embodiments of this disclosure provide a hoisting mechanism that is easy to clean, comprising:
[0008] A-frame hoisting scaffold;
[0009] The spreader is rotatably mounted between the two side plates of the portal frame and is used for lifting containers;
[0010] The driving component is located on both sides of the portal frame and is used to drive the spreader to rotate so as to tilt the container.
[0011] The outer wall impact beam is hinged to the lower side wall of the lifting device via two jacking cylinders;
[0012] Furthermore, hinged joints are provided at both ends of the top surface of the outer wall impact beam;
[0013] The hinged part is hinged to the upper side wall of the lifting device via a hinge shaft and a hinge arm;
[0014] The control module is configured to control the drive component to rotate the spreader to tilt the container, and during tilting, it is also configured to control the push cylinder to reciprocate to drive the outer wall impact beam to reciprocate to impact the outer wall of the container.
[0015] An auxiliary component is provided between the hinge portion and the hinge arm;
[0016] When cleaning and maintaining the outer wall impact beam, the auxiliary component rotates in the first direction to clean the dirt in the gap between the hinge and the hinge arm. After cleaning, the auxiliary component rotates in the second direction and simultaneously injects lubricating oil into the gap between the hinge and the hinge arm to complete the lubrication.
[0017] In one alternative embodiment, the hinge portion includes:
[0018] The first hinge plate and the second hinge plate are set opposite to each other;
[0019] The hinge arm is disposed between the first hinge plate and the second hinge plate and is connected by a hinge shaft.
[0020] In one alternative implementation, the auxiliary component includes:
[0021] The first cleaning disc and the second cleaning disc are both sleeved on the hinge shaft and located on both sides of the hinge arm;
[0022] The linkage is located on the top surface of the outer wall impact beam and below the hinge arm;
[0023] The linkage is connected to the side walls of the first cleaning disc and the second cleaning disc, respectively;
[0024] When the first cleaning disc moves along the hinge axis, the linkage drives the second cleaning disc to move towards or away from the first cleaning disc.
[0025] In one optional implementation, the linkage includes:
[0026] A rotating shaft is rotatably mounted on the top surface of the outer wall impact beam;
[0027] A rotating plate, the middle part of which is rotatably connected to the top of the rotating shaft;
[0028] Two connecting plates are respectively rotatably mounted at both ends of the rotating plate and connected to the bottom of the corresponding first cleaning disc and second cleaning disc;
[0029] When the first cleaning disc moves along the hinge axis toward the rotation axis, it drives the second cleaning disc to move toward the first cleaning disc, so as to reduce the gap between the first cleaning disc and the second cleaning disc and the hinge arm. When the first cleaning disc and the second cleaning disc rotate along the first direction, the dirt in the gap is cleaned.
[0030] After cleaning is completed, when the first cleaning disc moves away from the rotating shaft, it drives the second cleaning disc to move away from the second cleaning disc, so as to increase the gap between the first cleaning disc and the second cleaning disc and the hinge arm. When the first cleaning disc and the second cleaning disc rotate in the second direction, lubricating oil is introduced into the gap so that the lubricating oil enters the bearing at the connection between the hinge shaft and the hinge arm.
[0031] In one alternative embodiment, the first cleaning disc extends outward from the side facing the hinge arm to form a first frustum;
[0032] The sidewalls of the first frustum are provided with multiple first grooves and second grooves in an alternating manner;
[0033] The top surface of the first truncated cone is provided with a first cleaning port and a first oil outlet;

[0035] The first oil outlet is connected to the second tank.
[0036] In one alternative implementation, the first cleaning port is inclined along a first direction;
[0037] The first oil outlet is inclined in the second direction.
[0038] In one alternative embodiment, the first hinge plate and the second hinge plate are made using the same mold;
[0039] Furthermore, both the first hinge plate and the second hinge plate have two threaded holes.
[0040] The first hinge plate is fixed to the lower part of the hinge shaft by bolts and corresponding threaded holes to prevent the hinge shaft from rotating.
[0041] The auxiliary components also include:
[0042] A push rod, one end of which passes through a reset spring and the first hinge plate and is connected to the outer wall of the first cleaning disc.
[0043] In one optional embodiment, the outer wall of the first cleaning disc is provided with an annular groove, and the push rod passes through the first hinge plate and is slidably connected in the annular groove;
[0044] An external force is used to push the push rod, causing the first cleaning disc to move along the hinge axis.
[0045] Secondly, this disclosure also provides a hoisting machine, comprising:
[0046] Vehicle body;
[0047] Such as the lifting mechanism that is easy to clean;
[0048] The easy-to-clean hoisting mechanism is installed on the vehicle body.
[0049] Thirdly, this disclosure also provides a method of operation for a hoisting mechanism as described above that is easy to clean, the method comprising:
[0050] During pouring, the working method includes:
[0051] The container is lifted by controlling the spreader via the control module.
[0052] After the container is transported to the designated location, the control module controls the drive unit to rotate the spreader so as to dump the materials inside the container;
[0053] The control module controls the reciprocating motion of the push cylinder to drive the outer wall impact beam to reciprocate and impact the outer wall of the container.
[0054] During maintenance, the working method includes:
[0055] The control module places the spreader on the ground;
[0056] The auxiliary component is rotated in the first direction by external force to clean the dirt in the gap between the hinge and the hinge arm;
[0057] After cleaning, the auxiliary component is rotated in the second direction by external force, and lubricating oil is injected into the gap between the hinge and the hinge arm to complete the lubrication.
[0058] The beneficial effects of this invention are that the hoist, the easy-to-clean hoisting mechanism and its working method can directly clean the dirt and grime between the hinge part and the hinge arm by rotating the auxiliary part in the first direction during maintenance, without disassembling the hinge part, simplifying the maintenance process and avoiding the wear and tear of parts caused by frequent disassembly. At the same time, after cleaning, the auxiliary part can rotate in the second direction and simultaneously add lubricating oil, ensuring that the lubricating oil can fully penetrate into the bearing inside the hinge shaft and reduce wear.

[0075] Research has revealed that hinged joints in hoisting mechanisms (such as the connection between the hinge and the articulated arm) are prone to accumulating debris, dirt, and other impurities during long-term use. This is especially true when unloading bulk materials, where dust or particles can easily penetrate the gaps at the hinge. Long-term accumulation leads to accelerated wear at the hinge, affecting equipment flexibility and lifespan. Furthermore, cleaning and maintenance often require disassembling the hinge components, a tedious and time-consuming process, and frequent disassembly may further accelerate component wear. Additionally, reducing the gap to minimize debris and dirt accumulation can prevent lubricating oil from reaching the bearings of the articulated arm during subsequent lubrication.
[0076] Based on the above research, this disclosure provides a hoist, a hoisting mechanism that is easy to clean, and its working method. During maintenance, the auxiliary component 440 rotates in a first direction, which can directly clean the dirt between the hinge part 420 and the hinge arm 430 without disassembling the hinge part 420, simplifying the maintenance process and avoiding the wear and tear of parts caused by frequent disassembly. At the same time, after cleaning, the auxiliary component 440 rotates in a second direction and can simultaneously add lubricating oil, ensuring that the lubricating oil can fully penetrate into the bearing inside the hinge shaft 423, reducing wear.
[0077] The shortcomings of the above solutions are the result of the inventor's practical experience and careful research. Therefore, the discovery process of the above problems and the solutions proposed in this disclosure should be considered as the inventor's contribution to this disclosure.
[0078] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0079] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features can be combined with each other.
[0080] Please refer to Figures 1 and 2. At least one embodiment provides a lifting mechanism that is easy to clean, including: a portal-shaped lifting frame 100; a spreader 200, which is rotatably disposed between two side plates of the portal-shaped lifting frame 100 and used for lifting containers; a drive unit 300, which is disposed on both sides of the portal-shaped lifting frame 100 and used to drive the spreader 200 to rotate, thereby tilting the container; an outer wall impact beam 400, which is hinged to the lower side wall of the spreader 200 via two push cylinders 410; and, the two ends of the top surface of the outer wall impact beam 400 are provided with hinge portions 420; the hinge portions 420 are hinged to the upper side wall of the spreader 200 via hinge shafts 423 and hinge arms 430. The control module is configured to control the drive unit 300 to rotate the spreader 200 to tilt the container. During tilting, it is also configured to control the push cylinder 410 to reciprocate, causing the outer wall impact beam 400 to reciprocate and impact the outer wall of the container. An auxiliary component 440 is provided between the hinge portion 420 and the hinge arm 430. When cleaning and maintaining the outer wall impact beam 400, the auxiliary component 440 rotates in a first direction to clean the dirt and grime in the gap between the hinge portion 420 and the hinge arm 430. After cleaning, the auxiliary component 440 rotates in a second direction, simultaneously injecting lubricating oil into the gap between the hinge portion 420 and the hinge arm 430, thus completing the lubrication process.
[0081] By rotating the auxiliary component 440 in the first direction during maintenance, dirt can be directly cleaned from the gap between the hinge part 420 and the hinge arm 430 without disassembling the hinge part 420, simplifying the maintenance process and avoiding wear and tear on parts caused by frequent disassembly. At the same time, after cleaning, the auxiliary component 440 can rotate in the second direction and lubricating oil can be added simultaneously, ensuring that the lubricating oil can fully penetrate into the bearing inside the hinge shaft 423, reducing wear.
[0082] Please refer to Figures 1 and 2. The hinge portion 420 includes: a first hinge plate 421 and a second hinge plate 422 disposed opposite to each other; the hinge arm 430 is disposed between the first hinge plate 421 and the second hinge plate 422 and is connected by a hinge shaft 423.
[0083] Please refer to Figures 2 and 3. The auxiliary component 440 includes: a first cleaning disc 441 and a second cleaning disc 442, both of which are sleeved on the hinge shaft 423 and located on both sides of the hinge arm 430; and a linkage part 450, which is disposed on the top surface of the outer wall impact beam 400 and located below the hinge arm 430. The linkage part 450 is connected to the side walls of the first cleaning disc 441 and the second cleaning disc 442 respectively. When the first cleaning disc 441 moves along the hinge shaft 423, the linkage part 450 drives the second cleaning disc 442 to move towards or away from the first cleaning disc 441.
[0084] The linkage 450 enables the first cleaning disc 441 and the second cleaning disc 442 to move toward or away from each other. During cleaning, the gap is narrowed to scrape off dirt, and during lubrication, the gap is widened to introduce lubricating oil. This achieves synergy between cleaning and lubrication, cleaning dirt without affecting lubrication, and also eliminates the need to disassemble the various components.
[0085] Specifically, the linkage 450 includes: a rotating shaft 451, rotatably mounted on the top surface of the outer wall impact beam 400; a rotating plate 452, the middle part of which is rotatably connected to the top of the rotating shaft 451; and two connecting plates 453, respectively rotatably mounted at both ends of the rotating plate 452 and connected to the bottom of the corresponding first cleaning disc 441 and second cleaning disc 442; when the first cleaning disc 441 moves along the hinge shaft 423 toward the rotating shaft 451 (movement direction shown as F3 in Figure 2), it drives the second cleaning disc 442 to move toward the first cleaning disc 441, so as to move the first cleaning disc 441 and the second cleaning disc 442 together. 2. The gap between the hinge arm 430 and the first cleaning disc 441 and the second cleaning disc 442 is reduced. When the first cleaning disc 441 and the second cleaning disc 442 rotate in the first direction, the dirt in the gap is cleaned. After cleaning, when the first cleaning disc 441 moves away from the rotating shaft 451, it drives the second cleaning disc 442 to move away from the second cleaning disc 442, so as to increase the gap between the first cleaning disc 441 and the second cleaning disc 442 and the hinge arm 430. When the first cleaning disc 441 and the second cleaning disc 442 rotate in the second direction, lubricating oil is introduced into the gap so that the lubricating oil enters the bearing at the connection between the hinge shaft 423 and the hinge arm 430.
[0086] By rotating the plate 452 and connecting the plate 453 together, gently pushing the first cleaning plate 441 can synchronously drive the second cleaning plate 442, thereby causing the gap between the first cleaning plate 441 and the second cleaning plate 442 and the hinge arm 430 to decrease and increase synchronously.
[0087] Please refer to Figure 4. The first cleaning disc 441 extends outward from the side facing the hinge arm 430 to form a first frustum 441a. The sidewalls of the first frustum 441a are provided with a plurality of first grooves 441b and second grooves 441c in an alternating manner. The top surface of the first frustum 441a is provided with a first cleaning port 441d and a first oil outlet 441e. The first cleaning port 441d communicates with the first groove 441b. The first oil outlet 441e communicates with the second groove 441c.
[0088] The first cleaning port 441d is inclined along a first direction; the first oil outlet 441e is inclined along a second direction. The first cleaning port 441d is inclined along the first direction (as shown by F1 in Figures 1 and 3), which facilitates the cleaning of dirt by the first cleaning port 441d when the first cleaning disc 441 is rotated along the first direction by external force; the first oil outlet 441e is inclined along the second direction (as shown by F2 in Figures 1 and 3), which allows the lubricating oil injected from the second tank 441c to enter the bearing of the hinge arm 430 along the first oil outlet 441e when the first cleaning disc 441 is rotated along the second direction by external force, thus completing the lubricating oil filling.
[0089] It should be noted that the first hinge plate 421 and the second hinge plate 422 are made using the same mold; and both the first hinge plate 421 and the second hinge plate 422 have two threaded holes; the first hinge plate 421 fixes the limiting plate 425 below the hinge shaft 423 by bolts 424 and the corresponding threaded holes to prevent the hinge shaft 423 from rotating; the auxiliary component 440 also includes a push rod 426, and one end of the push rod 426 passes through the return spring 427 and the first hinge plate 421 and is connected to the outer wall of the first cleaning disc 441.
[0090] Since the first hinge plate 421 and the second hinge plate 422 are made using the same mold during mold opening, installation space is provided for the push rod 426, eliminating the need for additional mold design. At the same time, the push rod 426 cooperates with the return spring 427 to allow the first cleaning disc 441 to be moved directly from the outside, further simplifying maintenance operations and improving cleaning and maintenance efficiency.
[0091] Please refer to Figure 3. The outer wall of the first cleaning disc 441 is provided with an annular groove 441f. The push rod 426 passes through the first hinge plate 421 and is slidably connected in the annular groove 441f. The push rod 426 is pushed by an external force to make the first cleaning disc 441 move along the hinge axis 423.
[0092] The annular groove 441f ensures that the push rod 426 remains connected to the first cleaning disc 441 during sliding, preventing the push rod 426 from separating from the first cleaning disc 441 during subsequent pushing.
[0093] At least one embodiment also provides a hoisting machine, comprising: a vehicle body; a hoisting mechanism as described above for easy cleaning; the hoisting mechanism for easy cleaning is disposed on the vehicle body.
[0094] At least one embodiment also provides a working method for the hoisting mechanism described above that is easy to clean. By rotating the auxiliary component 440 in a first direction during maintenance, dirt can be directly cleaned from the gap between the hinge portion 420 and the hinge arm 430 without disassembling the hinge portion 420, simplifying the maintenance process and avoiding wear and tear on parts caused by frequent disassembly. At the same time, after cleaning, the auxiliary component 440 can rotate in a second direction and lubricating oil can be added simultaneously, ensuring that the lubricating oil can fully penetrate into the bearing inside the hinge shaft 423, reducing wear.
[0095] Please refer to Figure 5. During the pouring process, the working method includes:
[0096] The control module controls the spreader 200 to lift the container;
[0097] After the container is transported to the designated location, the control module controls the drive unit 300 to drive the spreader 200 to rotate, so as to dump the materials inside the container;
[0098] The control module controls the reciprocating motion of the push cylinder 410 to drive the outer wall impact beam 400 to reciprocate and impact the outer wall of the container.
[0099] During maintenance, the working method includes:
[0100] The control module places the spreader 200 on the ground;
[0101] The auxiliary component 440 is rotated in the first direction by external force to clean the dirt in the gap between the hinge portion 420 and the hinge arm 430.
[0102] After cleaning, the auxiliary component 440 is rotated in the second direction by external force, and lubricating oil is injected into the gap between the hinge part 420 and the hinge arm 430 to complete the lubrication.
[0103] In summary, the present invention provides a hoisting machine, a hoisting mechanism that is easy to clean, and its working method. During maintenance, the auxiliary component 440 rotates in a first direction, allowing direct cleaning of dirt and grime from the gap between the hinge part 420 and the hinge arm 430 without disassembling the hinge part 420. This simplifies the maintenance process and avoids wear and tear on parts caused by frequent disassembly. Simultaneously, after cleaning, the auxiliary component 440 rotates in a second direction and can simultaneously add lubricating oil, ensuring that the lubricating oil can fully penetrate into the bearing inside the hinge shaft 423, reducing wear.
