Description

Technical Field

[0001] This invention relates to the field of lifting equipment, and more specifically to container transport tilting lifting equipment for port cranes. Background Technology

[0002] Container transport tilting spreaders used for port cranes are core specialized equipment in port container loading and unloading operations. Their core function is to connect quay cranes, yard cranes, gantry cranes, and containers. Through an integrated action of "grabbing-tilting-aligning-releasing," they solve the problems of posture adjustment and efficient transfer of containers during transportation, storage, and loading and unloading.

[0003] When unloading existing open-top containers, if the container is filled with powdery cargo, the container is held and secured by the existing tilting spreader. The tilting spreader drives the container to rotate and dump the powdery cargo into a designated location. However, some powder cannot be detached from the container by gravity, leaving some powdery cargo inside. This requires manual or specialized equipment for cleaning, which directly increases operating costs and prolongs the "empty container dwell time," thus reducing work efficiency.

[0004] Therefore, we have made improvements to this and proposed a container transport tilting spreader for port cranes. Summary of the Invention

[0005] The purpose of this invention is to address the problem that when existing tilting spreaders unload open-top containers filled with powdery goods, some powdery goods remain inside the open-top containers, thus prolonging the "empty container dwell time" and reducing work efficiency.

[0006] To achieve the above-mentioned objectives, the present invention provides a container transport tilting spreader for port cranes to solve the aforementioned problems.

[0007] The application is as follows:

[0008] It includes a rotating frame, a mounting base rotatably mounted on the rotating frame, a rotating mechanism mounted on the rotating frame, a clamping mechanism mounted on the mounting base, an extension base mounted on the mounting base, and a striking mechanism mounted on the extension base;

[0009] The striking mechanism includes a cylinder mounted on the extension seat, a sliding groove mounted on the extension seat, a jacking block slidably mounted on the sliding groove, a drive shaft rotatably mounted on the extension seat, a bevel gear I mounted on the drive shaft, a threaded groove mounted on the drive shaft, a protrusion slidably mounted on the threaded groove, a worm gear I rotatably mounted on the extension seat, a bevel gear II mounted on the worm gear I, a transmission shaft I rotatably mounted on the extension seat, a worm wheel I mounted on the transmission shaft I, and a connecting plate I mounted on the transmission shaft I.

[0010] As a preferred technical solution of this application, the push block is disposed at the output end of the cylinder, the protrusion is disposed on the push block, and the first bevel gear and the second bevel gear are adapted to each other.

[0011] As a preferred technical solution of this application, a second worm is provided on the first worm, the second worm is rotatably mounted on the extension seat, a second transmission shaft is rotatably mounted on the extension seat, a second connecting plate is provided on the second transmission shaft, and a second worm wheel is provided on the second transmission shaft.

[0012] As a preferred technical solution of this application, the first worm and the first worm wheel are adapted to each other, and the second worm and the second worm wheel are adapted to each other.

[0013] As a preferred technical solution of this application, both the first connecting plate and the second connecting plate are provided with baffles, and the baffles are compatible with the mounting base.

[0014] As a preferred technical solution of this application, both the first connecting plate and the second connecting plate are provided with a fixed shaft, the baffle is rotatably mounted on the fixed shaft, and the baffle and the fixed shaft are connected by a torsion spring.

[0015] As a preferred technical solution of this application, both the first connecting plate and the second connecting plate are provided with rubber rings, and the rubber rings and the baffles are mutually compatible.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] In the scheme of this application:

[0018] 1. To address the problem in existing technologies where tilting spreaders leave residual powdery cargo inside open-top containers during unloading, thus prolonging the "empty container dwell time" and reducing work efficiency, this application proposes a striking mechanism. This mechanism drives connecting plates one and two to rotate and strike both sides of the open-top container's end, causing uniform vibration within the container. This vibration helps to clean the residual powdery cargo inside the container, reducing its accumulation and adhesion, thereby improving the overall efficiency of port operations.

[0019] 2. By setting a tapping mechanism, the angle of the baffle rotation is controlled, thereby controlling the discharge speed of powdery goods. This can reduce the dust generated during the discharge of powdery goods and solve the problem of dust generated during the discharge of powdery goods affecting the working environment in the prior art.

[0020] 3. By using a set-up knocking mechanism, the top of the open-top container is sealed with a baffle to prevent leakage of powdery goods inside the container during transfer, reduce dust diffusion, and reduce environmental pollution. This solves the problem of dust generated during the transfer of powdery goods affecting the surrounding environment in the prior art. Attached Figure Description

Detailed Implementation

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] As described in the background art, when a flipper unloads an open-top container filled with powdery goods, some powdery goods remain inside the container, thus prolonging the "empty container dwell time" and reducing work efficiency.

[0031] To address this technical problem, the present invention provides a container transport tilting spreader for port cranes, which is applied to container transport.

[0032] For details, please refer to Figure 1 - Figure 6 As shown, the container transport tilting spreader for port cranes specifically includes: a rotating frame 1, a mounting base 101 rotatably mounted on the rotating frame 1, a rotating mechanism 102 mounted on the rotating frame 1, a clamping mechanism 103 mounted on the mounting base 101, including an extension base 104 mounted on the mounting base 101, and a striking mechanism 105 mounted on the extension base 104. In the prior art, the rotating frame 1 is connected to an existing crane. The main function of the rotating mechanism 102 is to drive the mounting base 101 to rotate and realize the tilting action of the open-top container so as to dump the powdery goods inside the open-top container. The main function of the clamping mechanism 103 is to clamp and fix the open-top container to ensure that the open-top container will not slide or loosen during the tilting process.

[0033] The striking mechanism 105 includes a cylinder 2 mounted on an extension seat 104, a sliding groove 201 mounted on the extension seat 104, a jacking block 202 slidably mounted on the sliding groove 201, a drive shaft 203 rotatably mounted on the extension seat 104, a bevel gear 204 mounted on the drive shaft 203, a threaded groove 205 mounted on the drive shaft 203, a protrusion 206 slidably mounted on the threaded groove 205, a worm gear 207 rotatably mounted on the extension seat 104, a bevel gear 208 mounted on the worm gear 207, a transmission shaft 209 rotatably mounted on the extension seat 104, a worm wheel 210 mounted on the transmission shaft 209, and a connecting plate 211 mounted on the transmission shaft 209.

[0034] The container transport tilting spreader for port cranes provided by this invention addresses the problem in the prior art where tilting spreaders leave some powdery cargo inside open-top containers during unloading, thus prolonging the "empty container dwell time" and reducing work efficiency. This application incorporates a striking mechanism 105, which drives connecting plates 211 and 214 to rotate and strike both sides of the open-top container's end, causing uniform vibration in the container. This vibration helps to clean the residual powdery cargo inside the container, reducing its accumulation and adhesion, thereby improving the overall efficiency of port operations.

[0035] By using the set tapping mechanism 105, the angle of rotation of the baffle 216 is controlled by the tapping mechanism 105, thereby controlling the discharge speed of the powdery goods. This can reduce the dust generated during the discharge of the powdery goods and solve the problem of dust generated during the discharge of powdery goods affecting the working environment in the prior art.

[0036] By using the set knocking mechanism 105, the top of the open-top container is sealed by the baffle 216 to prevent leakage of powdery goods inside the open-top container during transfer, reduce the spread of dust, reduce environmental pollution, and solve the problem of dust affecting the surrounding environment during the transfer of powdery goods in the prior art.

[0037] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0038] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0039] 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.

[0040] Example 1, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the container transport tilting spreader used for port cranes has a top moving block 202 located at the output end of cylinder 2, a protrusion 206 located on the top moving block 202, and bevel gear 1 204 and bevel gear 208 mutually adapted to each other.

[0041] In use, the clamping mechanism 103 clamps and secures the open-top container, and then uses an existing crane to lift and transfer the open-top container to a designated location, such as... Figure 1 As shown, the rotating mechanism 102 drives the mounting base 101, clamping mechanism 103, and open-top container to rotate synchronously, causing the powdery cargo inside the open-top container to be poured into a designated position. When there is residual powdery cargo inside the open-top container, the cylinder 2 is activated. The cylinder 2 drives the jacking block 202 to slide along the sliding groove 201. The protrusion 206 on the jacking block 202 slides synchronously and presses against the threaded groove 205. At this time, the protrusion 206 slides along the threaded groove 205 and drives the drive shaft 203 to rotate. The bevel gear 204 on the drive shaft 203 rotates synchronously. The bevel gear 204 drives the bevel gear 208 to rotate. The bevel gear 208 drives the worm gear 207 to rotate. The worm gear 207 drives the worm wheel 210 to rotate. The worm wheel 210 drives the transmission shaft 209 and the connecting plate 211 to rotate synchronously. Figure 6 As shown, by driving the output end of the cylinder 2 to drive the top block 202 to slide back and forth along the sliding groove 201, the connecting plate continuously swings left and right and knocks on the top of the open-top container, causing the open-top container to vibrate. Vibration helps to clean the residual powdery cargo inside the open-top container, which can reduce the accumulation and adhesion of powdery cargo inside the container, thereby improving the overall efficiency of port operations.

[0042] Furthermore, a second worm 212 is provided on the first worm 207, the second worm 212 is rotatably mounted on the extension seat 104, a second drive shaft 213 is rotatably mounted on the extension seat 104, a second connecting plate 214 is provided on the second drive shaft 213, and a second worm wheel 215 is provided on the second drive shaft 213.

[0043] When Figure 3As shown, worm gear 1 207 and worm gear 212 are on the same horizontal line and connected together. When worm gear 1 207 rotates, worm gear 212 rotates synchronously. The thread directions of worm gear 1 207 and worm gear 212 are opposite. Therefore, when worm gear 212 rotates and drives worm wheel 215, drive shaft 213 and connecting plate 214 to rotate, connecting plate 1 211 and connecting plate 214 rotate in opposite directions. The cylinder 2 drives connecting plate 1 211 and connecting plate 214 to rotate and strike the two sides of the top of the open-top container, so that the vibration is evenly distributed on the open-top container. The uniform vibration can loosen the powdery goods in the open-top container, reduce the friction between the powdery goods, and make it easier to clean them out of the container. This prevents the situation where vibration in a single place may only loosen the powdery goods in a local area, resulting in incomplete cleaning.

[0044] Furthermore, worm gear 207 and worm wheel 210 are mutually compatible, and worm gear 212 and worm wheel 215 are mutually compatible.

[0045] Worm 1 207 has a self-locking function to worm wheel 1 210, and worm 2 212 has a self-locking function to worm wheel 2 215. When worm 1 207 and worm 2 212 are not rotating, connecting plate 1 211 and connecting plate 2 214 will also be unable to rotate, preventing connecting plate 1 211 and connecting plate 2 214 from being affected by gravity and causing themselves to rotate.

[0046] The striking mechanism 105 drives the connecting plate 211 and the connecting plate 214 to rotate and strike both sides of the open-top container, causing the open-top container to vibrate evenly. This vibration helps to clean the residual powdery cargo inside the open-top container, reducing the accumulation and adhesion of powdery cargo inside the container, thereby improving the overall efficiency of port operations.

[0047] Example 2 further optimizes the container transport tilting spreader for port cranes provided in Example 1, specifically, as follows: Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, both the first connecting plate 211 and the second connecting plate 214 are provided with baffles 216, which are compatible with the mounting base 101.

[0048] like Figure 1As shown, the top of the open-top container is sealed by baffle 216 to prevent leakage of powdery goods during transfer. Since powdery goods easily generate dust during transfer, this dust not only pollutes the environment but may also harm the health of surrounding personnel. Sealing with baffle 216 effectively reduces dust diffusion and environmental pollution. When the powdery goods are emptied from the open-top container, connecting plates 211 and 214 are rotated, and the baffle 216 on both plates rotates synchronously. By controlling the rotation angle of the baffle 216, the discharge speed of the powdery goods is controlled. This reduces dust generation during discharge, especially for goods that easily generate dust (such as ore powder, coal powder, and grain powder). Controlling the discharge speed reduces dust diffusion. Figure 2 As shown, the two baffles 216 are designed to open, so that the powdery goods discharged are guided by the two baffles 216 and discharged in the center of the open top container, thus preventing leakage during the unloading process.

[0049] Furthermore, both the first connecting plate 211 and the second connecting plate 214 are provided with a fixed shaft 217, and the baffle 216 is rotatably mounted on the fixed shaft 217. The baffle 216 and the fixed shaft 217 are connected by a torsion spring 218.

[0050] During the pouring process, the powdery goods spill out and compress the baffle 216. The elasticity of the torsion spring 218 causes the baffle 216 to rotate adaptively, buffering the impact force generated during the pouring process. This improves the service life of the baffle 216. The initial state of the baffle 216 is horizontal with both the first connecting plate 211 and the second connecting plate 214. Figure 2 As shown;

[0051] Furthermore, both the first connecting plate 211 and the second connecting plate 214 are provided with rubber rings 219. The rubber rings 219 and the baffle 216 are adapted to each other, and the friction between the first connecting plate 211, the second connecting plate 214 and the rubber rings 219 is increased by the rubber rings 219.

[0052] The angle of rotation of the baffle 216 is controlled by the striking mechanism 105, thereby controlling the discharge speed of the powdery cargo. This reduces the dust generated during the discharge process. The baffle 216 also seals the top of the open-top container to prevent leakage of the powdery cargo during transfer, thus reducing dust diffusion and environmental pollution.

[0053] The container transport tilting spreader for port cranes provided by this invention is used as follows:

[0054] In use, the clamping mechanism 103 clamps and secures the open-top container, and the container is lifted and transferred to a designated location using an existing crane. A baffle 216 seals the top of the open-top container to prevent leakage of powdery goods during transfer. The rotating mechanism 102 drives the mounting base 101, clamping mechanism 103, and open-top container to rotate synchronously, causing the powdery goods inside the container to be poured into the designated location. The cylinder 2 is activated, driving the top block 202 along the sliding... When the moving groove 201 slides, the protrusion 206 on the top moving block 202 slides synchronously and presses against the threaded groove 205. At this time, the protrusion 206 slides along the threaded groove 205 and drives the drive shaft 203 to rotate. The first bevel gear 204 on the drive shaft 203 rotates synchronously. The first bevel gear 204 drives the second bevel gear 208 to rotate. The second bevel gear 208 drives the first worm 207 to rotate. The second worm 212 rotates synchronously. The thread directions of the first worm 207 and the second worm 212 are opposite. The second worm 212 rotates and drives the second worm wheel 215 and the transmission... The rotating shaft 213 and connecting plate 214 cause the worm gear 207 to drive the worm wheel 210 to rotate. The worm wheel 210 then drives the transmission shaft 209 and connecting plate 211 to rotate synchronously. At this time, the rotation directions of connecting plate 211 and connecting plate 214 are opposite. The output end of the driving cylinder 2 drives the top block 202 to slide back and forth along the sliding groove 201, causing the connecting plate 211 and connecting plate 214 to rotate and strike the two sides of the top of the open-top container. This vibration helps to clean the residue inside the open-top container. When the powdery goods are discharged, the discharge speed of the powdery goods is controlled by adjusting the rotation angle of the baffle 216. This reduces the dust generated during the discharge process. The elasticity of the torsion spring 218 allows the baffle 216 to rotate adaptively, buffering the impact force generated when the powdery goods are discharged and improving the service life of the baffle 216. When all the powdery goods are discharged, the baffle 216 is kept on the same horizontal plane as the connecting plate 1 211 and the connecting plate 214 respectively.
