Abstract
Description
Technical Field
[0001] This invention relates to the field of cargo transfer technology, and in particular to a heavy cargo transfer device and transfer method. Background Technology
[0002] Rail transit structures such as axles and hubs need to be manufactured by casting using sand molds. The sand molds used for these large structures are large in volume and heavy in weight.
[0003] The casting sand mold needs to move along a predetermined production line, going through processes such as sand preparation, mold preparation, casting, and demolding. During the production process, it needs to move continuously in different production areas via a conveyor line.
[0004] To reduce the volume of the sand mold workshop, the production lines for casting sand molds are usually designed in parallel. Transfer devices are set at both ends of the production line to transfer and reverse the sand molds, forming a cycle in the casting sand mold production line and improving the production efficiency of casting sand molds. Existing heavy cargo transfer devices have a stable structure, transferring casting sand molds through track structures at both ends. However, for heavy sand molds, their overall mass is large, especially in the cooling stage after casting. The large overall mass results in high inertia during movement. During the transfer phase, the end-of-line obstruction structure of the transfer equipment experiences significant impact, making it a vulnerable part that requires regular replacement and poses a safety hazard. At the same time, the sudden decrease in speed at the end of the transfer process causes a certain impact on the transfer equipment and the casting sand mold as a whole, affecting the lifespan of the transfer equipment and the quality of the finished sand mold.

[0012] Preferably, the lifting drive device includes a drive mounting base, a drive screw is rotatably connected to the side wall of the drive mounting base, the drive screw passes through the lifting sliding seat and is threadedly connected to it, a second electronic control device is installed on the side wall of the drive mounting base for controlling the rotation of the drive screw, a guide rod is provided on the side wall of the drive mounting base for passing through the lifting sliding seat, and a locking assembly is provided between the bottom of the lifting sliding seat and the upper surface of the bearing body.
[0013] Preferably, the positioning device includes two spaced positioning points.

Simultaneously, the positioning device can determine the lateral and deflection coordinates of the guide rail components, enabling automatic positioning and ensuring accurate alignment between the guide rail components and the predetermined track. This improves transport efficiency and reduces risks during heavy cargo transportation. Attached Figure Description

[0031] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0032] See attached document Figure 1 - Appendix Figure 8 A heavy cargo transfer device includes a carrying body 100 for carrying cargo and a moving drive device 200 for driving the carrying body 100 to move linearly. The moving drive device 200 can control the carrying body 100 to move in different areas and move continuously between the loading area and the unloading area of heavy cargo to meet the needs of cargo transportation.
[0033] A cargo carrier frame 120 is provided at the upper end of the main body 100, and a rolling device 110 is provided at the lower end of the main body 100. The rolling device 110 can be selected as a combination of wheelset 111 and I-beam rail 112 to meet the transportation needs of heavy cargo. The first end of the cargo carrier frame 120 is rotatably connected to the upper end of the main body 100 through a rotating connection assembly 400. A lifting device 500 is provided on the surface of the main body 100 at the second end of the cargo carrier frame 120. The lifting device 500 controls the cargo carrier frame 120 to deflect by a predetermined angle, so that the cargo carrier frame 120 deflects by a predetermined angle toward the cargo. After deflection, the cargo moves in an obliquely upward direction. The gravity of the cargo will generate a component force opposite to the direction of the cargo movement, which can slow down the movement speed of the cargo, reduce the effect of cargo inertia, avoid the impact of the cargo on the end, and ensure the stability of the cargo.
[0034] It should be noted that the first end is the end closer to the cargo loading entrance, and the second end is the end farther away from the cargo loading entrance. The rotation design of the end closer to the cargo loading entrance can improve the overall load and ensure the stability of cargo movement. Compared with the rotation design of the side farther away, it can improve the stability of the structure and its service life.
[0035] A guide rail assembly 300 is installed on the upper end of the cargo carrier 120. The guide rail assembly 300 can guide heavy cargo. The guide rail assembly 300 adopts an I-beam design, which can reduce the surface friction coefficient and ensure the strength and service life of the overall structure. The guide rail assembly 300 is preferably a combination of a conveying guide rail 310 and a blocking guide rail 320. The blocking guide rail 320 is located at the second end of the cargo carrier 120, that is, at the end of the cargo movement. It is located on the movement path of the cargo and can further slow down the movement of the cargo, prevent the cargo from sliding out of the bearing area, prevent the cargo from exceeding the predetermined range, and ensure the stability of the cargo during the support and movement process. The blocking guide rail 320 is designed to be inclined towards the cargo direction, and its top end forms an obtuse angle of less than 180° with the upper plane of the conveying guide rail 310.
[0036] A positioning device 600 is installed on the side of the guide rail assembly 300 near the rotating connection assembly 400. The positioning device 600 determines the lateral and deflection coordinates of the guide rail assembly 300, ensuring accurate alignment between the guide rail assembly 300 and the cargo-moving rail. The positioning device 600 is electrically connected to the moving drive device 200, which precisely controls the horizontal direction of the guide rail assembly 300. Simultaneously, the positioning device 600 is connected to the lifting device 500. The electrical connection allows for control of the lifting device 500 based on the overall deflection angle of the guide rail assembly 300. This ensures that the lifting device 500 can be adjusted comprehensively according to the weight and size of the goods, thereby guaranteeing accurate control of the tilt angle of the guide rail assembly 300. The positioning device 600 can be a laser positioning element. A receiving panel is located on one side of the guide rail assembly 300, and the laser emitting end is fixedly installed on one side of the heavy goods conveyor line. It can emit a positioning laser in the direction of the guide rail assembly 300, thereby precisely controlling the lateral and deflection coordinates of the guide rail assembly 300.
[0037] Through the above-mentioned setup, overall automatic control and transfer transportation can be achieved, improving the automation level of cargo transportation. At the same time, the receiving position and receiving area of the positioning device 600 can be adjusted. Based on the quality of the cargo and the distance the cargo moves, a comprehensive judgment is made to select a suitable tilt angle to meet the requirements of cargo transfer transportation and ensure the stability of cargo transfer transportation.
[0038] Specifically, the mobile drive device 200 consists of two symmetrically arranged sets, located on both sides of the carrying body 100. These sets pull the carrying body 100 from both sides, allowing it to move the heavy cargo it supports between the loading and unloading areas, thus completing the cargo transfer. Each mobile drive device 200 includes a first electronic control device 210. A drive shaft 220 is fixedly connected to the rotating end of the first electronic control device 210. A drive assembly is mounted on the surface of the drive shaft 220, and a traction member 230, fixedly connected to the side wall of the carrying body 100, is sleeved on the surface of the drive assembly. The drive assembly and traction member 230 can be selected from various combinations, such as a combination of a winding roller and a steel cable, or a combination of a drive sprocket and a drive chain. This works in conjunction with the rolling device 110 below to allow the entire cargo to move linearly along a predetermined track.
[0039] Furthermore, the rotating connection assembly 400 includes a first rotating connection base 410 fixedly connected to the upper end of the supporting body 100, and a second rotating connection base 430 fixedly connected to the first end of the cargo carrier 120. The first rotating connection base 410 and the second rotating connection base 430 are rotatably connected by a connecting shaft 420. The second rotating connection base 430 is fixed to the outer side wall of the cargo carrier 120. The rotating connection assembly 400 is symmetrically arranged on both sides to support the cargo carrier 120. At the same time, there is a predetermined gap between the cargo carrier 120 and the supporting body 100, allowing the cargo carrier 120 to deflect normally at a predetermined angle. The first rotating connection base 410, the connecting shaft 420, and the second rotating connection base 430 on both sides are detachably designed to facilitate overall assembly and maintenance, and to ensure the stability of the overall structure.
[0040] To improve the supporting and load-bearing effect of the lifting device 500 on heavy goods, there is a predetermined distance between the lifting device 500 and the second end of the cargo carrier 120. The lifting device 500 includes a lifting support rod 510 fixedly connected to the second end of the cargo carrier 120. The lifting device 500 controls the deflection of the cargo carrier 120 from the outside through the lifting support rod 510. The lifting support rod 510 can act as a lever to lift the second end of the cargo carrier 120 from the outside, so that the overall structure can be raised to a predetermined height, ensuring the stability of the overall structure. Through the above structural design, the cargo carrier 120 and the goods above it can be lifted and moved with a smaller structure, reducing the load requirements on the structure of the lifting device 500.
[0041] Please refer to the appendix for details. Figure 4 Appendix Figure 6 and appendix Figure 8As one embodiment of the lifting structure, the lifting device 500 includes a lifting sliding seat 530. The upper end of the lifting sliding seat 530 has an installation notch, and a lifting control rod 520 is rotatably connected within the installation notch. The end of the lifting control rod 520 is rotatably connected to the lifting support rod 510 to form a rotating joint 521. A lifting drive device 540 is provided on the surface of the support body 100 to control the movement of the lifting sliding seat 530. Here, the lifting control rod 520 and the lifting support rod 510 are arranged crosswise, forming an angle of less than 180°. During the movement of the lifting sliding seat 530 toward the cargo support frame 120, the lifting control rod 520 rotates counterclockwise as a whole. When deflection occurs, the lifting support rod 510 deflects clockwise. During this process, the lifting support rod 510 can drive the cargo support frame 120, which is fixedly connected at the end, to deflect as a whole, thereby lifting the second end of the cargo support frame 120. The surface of the cargo support frame 120 deflects towards the direction of the heavy cargo. At the same time, while controlling the descent of the cargo support frame 120 and the heavy cargo, the lifting sliding seat 530 is controlled to move away from the cargo support frame 120. The angle formed by the lifting support rod 510 and the lifting control rod 520 below increases. The lifting support rod 510 controls the second end of the cargo support frame 120 to descend until the cargo support frame 120 and the heavy cargo are close to horizontal.
[0042] Similarly, a hydraulic telescopic rod or similar structure can be directly installed at the end of the lifting support rod 510 to control the lifting angle of the lifting support rod 510 and control the deflection of the second end of the cargo support frame 120.
[0043] As a preferred lifting drive method, the lifting drive device 540 includes a drive mounting base 541. A drive screw 542 is rotatably connected to the side wall of the drive mounting base 541. The drive screw 542 passes through the lifting sliding seat 530 and is threadedly connected to it. A second electronic control device 543 is installed on the side wall of the drive mounting base 541 to control the rotation of the drive screw 542. A guide rod is provided on the side wall of the drive mounting base 541, passing through the lifting sliding seat 530. During the process of the second electronic control device 543 controlling the rotation of the drive screw 542, the lifting sliding seat 530 can be driven to move linearly along the direction of the guide rod, controlling the lifting and lowering of the overall structure. At the same time, during this process, the linear movement of the lifting sliding seat 530 can be precisely controlled by the drive screw 542 to ensure the accuracy of the overall deflection angle of the end cargo carrier 120. The drive screw 542 can also be used to lock the lifting sliding seat 530 to ensure that the lifting sliding seat 530 can effectively bear the heavy cargo after being lifted, ensuring the stability of the overall structure.
[0044] To further ensure the stability of the lifting sliding seat 530 structure and distribute the impact during the movement of heavy goods, a locking assembly 550 is provided between the bottom of the lifting sliding seat 530 and the upper surface of the supporting body 100. The locking assembly 550 connects the lifting sliding seat 530 and the supporting body 100, locking the lifting sliding seat 530 from the bottom to ensure the overall structure is in a stable position. The locking assembly 550 can be a combination of locking opening 551 and locking element 552. The locking element 552 can be a hydraulically controlled telescopic mechanism with a cast iron locking pin fixed at the telescopic end. During the locking process, it extends into the locking opening 551 and locks crosswise to ensure the stability of the overall structure. Depending on the specifications of the heavy goods being transported, multiple locking openings 551 can be provided on the surface of the supporting body 100. In this case, locking can be achieved even when the cargo carrier 120 forms different tilt angles.
[0045] Please refer to the appendix for details. Figure 7 The positioning device 600 here includes two spaced positioning points. The first positioning point determines the lateral coordinates, and the second positioning point determines the deflection coordinates. The positioning device 600 is a laser positioning element. Specifically, a laser receiving positioning element is installed on one side of the heavy cargo conveyor track, and a laser generator is installed to continuously emit laser light in the direction of the guide rail assembly 300. During this process, when the guide rail assembly 300 moves to the predetermined lateral position, the laser light corresponds to the positioning device 600, thereby determining the lateral coordinates of the guide rail assembly 300. After the lateral coordinates are accurately determined, the moving drive device 200 stops operating. At this time, the lifting device 500 controls the overall deflection of the guide rail assembly 300. During the deflection of the guide rail assembly 300, the angular position of the positioning device 600 will deflect, and the point projected by the laser tip will shift from the first positioning point to the side of the second positioning point. When the point projected by the laser tip coincides with the second positioning point, the positioning device 600 receives the overall positioning signal, the overall structure is accurately determined, and the lifting device 500 is controlled to stop moving, achieving deflection locking and ensuring that the overall structure is positioned.
[0046] The above positioning method can accurately control the lateral position and tilt angle of the guide rail assembly 300, ensuring that the guide rail assembly 300 can accurately connect with the conveyor rail, avoiding collisions between goods during the movement of the connection point, ensuring normal movement of goods, and protecting the overall device from damage caused by the impact of heavy goods.
[0047] Some production workshops have harsh environments with significant amounts of dust, sand, and other impurities. To protect local structures and ensure accurate laser positioning of the positioning device 600, a protective component 700 is rotatably mounted on the outside of the positioning device 600. A protective area 900 is formed between the protective component 700, the positioning device 600, and the guide rail assembly 300. Inside the guide rail assembly 300, a rotation control component 800 is installed to control the rotation of the protective component 700. After the guide rail assembly 300 moves into the loading area, the rotation control component 800 is pre-controlled to rotate, causing the protective component 700 to rotate to the outside. At this point, the protective component 700 is controlled to rotate to the outer edge. Figure 7 The state shown is offset from the positioning device 600, allowing the laser to pass through normally for positioning. After positioning, the rotation control component 800 controls the protection component 700 to rotate towards the positioning device 600, allowing the protection component 700 to rotate onto the surface of the positioning device 600, thus providing physical protection for the positioning device 600 and ensuring the stability of the overall structure. After the protection component 700 rotates to the outside, the protection area 900 formed between the protection component 700 and the guide rail component 300 can protect the positioning device 600, preventing external impurities from entering and affecting the positioning.
[0048] The protective component 700 includes a rotating mounting rod 710 and a protective plate 720. The protective plate 720 is fixedly connected to the rotating mounting rod 710. A protective groove is formed on the side wall of the protective plate 720. The cross-sectional dimension of the protective groove is larger than that of the positioning device 600. The positioning device 600 is located on the rotation path of the protective component 700. An elastic sealing gasket is fixed at the edge of the protective plate 720, allowing it to fit snugly against the outer side of the positioning device 600. The protective plate 720 can completely cover the outer side of the positioning device 600, protecting the inner side of the positioning device 600 and ensuring the stability of the overall structure. The protective groove also protects the protruding receiving part, adapts to the positioning device 600, and prevents direct contact with the surface of the positioning device 600, thus avoiding contamination.
[0049] The rotation control component 800 is preferably a pneumatic control component. The rotation control component 800 has an air outlet 842 at its top, which is located within the protection area 900. A sensing element is provided at the bottom of the guide rail assembly 300 to detect the deflection state of the guide rail assembly 300. After the guide rail assembly 300 deflects, a control signal is sent to the rotation control component 800 to control it to be in working condition. The rotation control component 800 is connected to an external air pump. In working condition, it can control the rotation end of the rotation control component 800 to drive the protection component 700 to deflect, thereby achieving rotation control. At the same time, the residual air of the rotation control component 800 is blown out from the air outlet 842 at the top and blown into the protection area 900, forming a high-pressure area within the protection area 900 to prevent external dust from entering and to ensure the cleanliness of the internal structure.
[0050] The rotation control component 800 here can be selected as a combination of a control shaft 810, a first control plate 820, a second control plate 830, and a control cylinder 840. The upper end of the control shaft 810 passes through the control cylinder 840 and is fixedly connected to the bottom of the protection component 700. The first control plate 820 is fixedly connected to the inner wall of the control cylinder 840, and the second control plate 830 is fixedly connected to the control shaft 810. A control chamber is formed between the first control plate 820 and the second control plate 830, and an elastic element is provided between them. Under the action of the elastic element, the protection component 700 can be normally in contact with the positioning device 600. During the laser positioning process, the high-pressure gas of the pumping device is pumped into the control chamber, which pushes the second control plate 830 to drive the control shaft 810 to deflect, thereby realizing the rotation control of the protection component 700.
[0051] A method for transshipping heavy cargo includes the following steps:
[0052] S1. The drive unit 200 controls the drive carrier 100 to move to the loading area, and the lifting unit 500 controls the cargo carrier 120 to deflect at a predetermined angle in the first direction. That is, the upper surface of the cargo carrier 120 deflects at a predetermined angle towards the heavy cargo side, so that the cargo moves diagonally upward during the conveying process, decelerating the moving cargo and preventing the heavy cargo from moving to the end under the action of inertia and hitting the end limit device, thus ensuring the stability and life of the overall structure. The deflection angle here is determined by the mass and volume of the heavy cargo and the distance it moves on the upper end of the cargo carrier 120. The angle formed with the ground is usually between 1 and 5°.
[0053] It should be noted that the conveyor track corresponding to the cargo loading area is also inclined, which is adapted to the 120° deflection angle of the cargo support frame to ensure the smooth transport of heavy cargo between the two and avoid serious local damage, which would result in significant structural loss.
[0054] S2. After the heavy cargo moves a predetermined distance along the guide rail assembly 300, the lifting device 500 controls the cargo carrier 120 to deflect at a predetermined angle in the second direction, which is opposite to the first direction. At this time, after the cargo moves beyond the general projected area to the surface of the cargo carrier 120, the lifting device 500 controls the cargo carrier 120 to deflect and descend in the second direction, ensuring that the heavy cargo is finally transported in a horizontal and stable state.
[0055] S3. After the heavy goods are scheduled to the target position, the mobile drive device 200 controls the drive body 100 and the heavy goods to move to the unloading area to complete the unloading. At this time, the heavy goods move from the loading area to the unloading area, and the goods on the surface of the overall transfer device are moved to the unloading track corresponding to the unloading area, thus completing the unloading of the goods. The overall device moves back and forth between the loading area and the unloading area to realize the continuous transfer of goods.
[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
