Description

Technical Field

[0001] The present application belongs to the technical field of container loading and unloading equipment, and specifically relates to a container side lifting and transshipment system. Background Art

[0002] As China vigorously develops container intermodal transport, railway container transport has grown significantly. As a result, the applicability, automation, and efficiency of container transfers between various modes of transport are attracting increasing market attention.

[0003] Currently, the primary equipment used for container loading and unloading in road-rail intermodal transport consists of rail-mounted gantry cranes, rubber-tyred gantry cranes, and reachstackers. While these devices can handle various container sizes, they must operate while the electrified railway network is disconnected, preventing offline operations. When the electrified railway network is still operational, only heavy-duty forklifts are sufficient, but these can only handle 20-foot containers and have a low level of automation.

[0004] By the end of 2020, the proportion of electrified railways in my country will exceed 70%, and the electrification level of major railway branches will continue to increase.

[0064] In order for those skilled in the art to which the present application belongs to more clearly understand the present application, the technical solutions of the present application will be described in detail below with specific embodiments in conjunction with the accompanying drawings.

[0065] To solve the technical problems of the prior art that the multimodal transport equipment switching is not flexible and interferes with the railway power grid line, the application provides a container side lifting and transfer system 100 which is arranged beside a railway line and can directly dock with a railway flat car to load and unload containers 200. According to the functions of each area where the container side lifting and transfer system 100 is located, the area where the container rail-road combined transport side loading and unloading system is located can be divided into the following areas: a railway loading and unloading area (A area) and a highway loading and unloading area (B area). The railway loading and unloading area (A area) is a railway flat car driving area, and when the railway flat car is parked beside the loading and unloading system, the loading and unloading of the container 200 can be carried out. The highway loading and unloading area (B area) is an area where a container truck (referred to as a container truck) drives or a container is stored, and when the container truck is parked beside the loading and unloading system, the loading and unloading of the container 200 can be carried out.

[0066] In the field of railway transportation, the extension direction of the rail is usually referred to as "longitudinal direction"; the direction perpendicular to the "longitudinal direction", that is, the direction in which the rails are spaced apart, is referred to as "transverse direction", so in the container side lifting and transfer system 100 of the application, the "longitudinal direction" and "transverse direction" in the extension direction and distribution direction of each part also adopt the above definitions. The content of the application will be described in detail below through specific embodiments:

[0067] The structure of the container side lifting and transfer system 100 is shown in Figures 1 to 4 The container side lifting and transfer system 100 is arranged in the highway loading and unloading area (B area), the walking device 10 is connected with the support assembly 20, which can drive the support assembly 20, the translation beam assembly 30, the first transverse expansion mechanism 40, the transverse beam assembly 50, the second transverse expansion mechanism 60 and the lifting assembly 70 as a whole along the railway to sequentially load and unload the containers 200 on the railway flat car. The support assembly 20 is close to the railway loading and unloading area (A area), so that the container rail-road transfer can be carried out, and the support assembly 20 simultaneously serves as the installation base of other components (the support assembly 20, the translation beam assembly 30, the first transverse expansion mechanism 40, the transverse beam assembly 50, the second transverse expansion mechanism 60 and the lifting assembly 70) of the container side lifting and transfer system 100. The translation beam assembly 30 and the transverse beam assembly 50 can move in the transverse direction, thereby transferring the container 200.

[0068] The support component 20 comprises at least four spaced-apart lifting legs 21, and a travelling area is formed between any two adjacent lifting legs 21 for the truck or other container transport vehicle to travel. The lifting legs 21 are used to mount the translation beam component 30 and the travelling device 10. According to actual needs, the number of the lifting legs 21 can be set to 4, 6, 8, 12, etc. To ensure force balance, the number of the lifting legs 21 is an even number, and the lifting legs 21 are symmetrically distributed in the transverse and longitudinal directions. For example, when the number of the lifting legs 21 is 4, the four lifting legs 21 are distributed at the four corners of a rectangle. The distance between any two adjacent lifting legs 21 in the longitudinal direction should be greater than the length of a 40ft / 45ft container, so as to ensure that the container can pass smoothly between the two lifting legs 21. The distance between any two adjacent lifting legs 21 in the transverse direction should be greater than the width of the truck, so as to ensure that the truck can travel smoothly.

[0069] Correspondingly, the number of the travelling devices 10 can be set to two or more. For example, when the number of the lifting legs 21 is 4, one set of the travelling device 10 is mounted at the bottom end of each lifting leg 21, and the travelling devices 10 operate synchronously. For another example, when the number of the lifting legs 21 is 6, one set of the travelling device 10 is mounted at the bottom end of each of the four lifting legs 21 located at the outer sides, and only travelling wheels are mounted on the lifting legs located at the middle. For another example, when the number of the lifting legs 21 is 4, one set of the travelling device 10 is mounted at the bottom end of each of the two lifting legs 21 located at the opposite corners, and the travelling devices 10 operate synchronously. For another example, only travelling wheels are mounted on the two lifting legs 21 located at the opposite corners. The arrangement modes of the travelling devices 10 are not exhaustively listed here.

[0070] The travelling device 10 is a mature prior art, and can refer to the railway vehicle travelling device or the travelling mechanism of the portal crane or the shore crane disclosed in the prior art. The specific structure is not described here again. In this embodiment, the travelling device 10 comprises a motor and two rollers, and the connection structure of the motor and the rollers can refer to the related disclosure in the prior art, which is not described here.

[0071] The translation beam component 30 is mounted at the top of the lifting leg 21. To facilitate the installation of the translation beam component 30, the support component 20 further comprises at least two first side beams 22, which are spaced apart in the longitudinal direction. To stabilize the first side beams 22, each first side beam 22 is connected with at least two transversely adjacent lifting legs 21. For example, when the number of the lifting legs 21 is 4, the four lifting legs 21 are distributed in a rectangular shape, and two first side beams 22 are correspondingly provided, which are both arranged in the transverse direction and connected with the two transversely adjacent lifting legs 21, and are used to mount the translation beam component 30.

[0072] In order to strengthen the structure of the support assembly 20, the support assembly 20 further comprises at least one first connecting longitudinal beam 23, both ends of the first connecting longitudinal beam 23 are connected with two adjacent first side beams 22 respectively, and the first connecting longitudinal beam 23 can be provided with one or two to connect two first side beams 22 distributed longitudinally. In some embodiments, in order to strengthen the structure of the support assembly 20, the support assembly 20 further comprises at least one second connecting longitudinal beam 24, both ends of the second connecting longitudinal beam 24 are connected with two longitudinally adjacent lifting legs 21 respectively, and the second connecting longitudinal beam 24 can be provided with one or more, preferably the number of the second connecting longitudinal beam 24 is half of the number of the lifting leg 21, that is, two second connecting longitudinal beams 24 are provided corresponding to four lifting legs 21 distributed in the long side of the rectangle, and the two second connecting longitudinal beams 24 are distributed in the long side of the rectangle.

[0073] The translation beam assembly 30 is an important part of the container side lifting transfer system 100, the translation beam assembly 30 is movably installed on the support assembly 20, and both ends of the translation beam assembly 30 are distributed on the transverse two sides, that is, the translation beam assembly 30 spans the railway flat car, the walking device 10 and the highway loading and unloading area, providing a track 32 basis for the horizontal movement of the horizontal translation beam assembly 50 and the spreader assembly 70. On the other hand, since the translation beam assembly 30 can move on the support assembly 20, when the translation beam assembly 30 moves away from the railway flat car, there is no obstruction on the railway flat car side of the container side lifting transfer system 100, so as not to interfere with the running of the traction locomotive pulling the railway flat car.

[0074] The core component of the translation beam assembly 30 is the telescopic beam 31, which is assembled on the first side beam 22, so the number of the telescopic beam 31 is the same as that of the first side beam 22, and each translation beam assembly 30 is installed on each first side beam 22 one by one. The telescopic beam 31 is an integral beam, in order to meet the needs of container transfer, in the transverse direction, that is, the telescopic beam 31 axial direction, the telescopic beam 31 can be divided into a railway side segment 31a and a highway side segment 31b, and the length of each segment of the telescopic beam 31 should be able to cover the corresponding railway loading and unloading area (A area) and highway loading and unloading area (B area) below. The telescopic beam 31 needs to move horizontally on one hand, and the telescopic beam 31 needs to provide a horizontal movement track 32 for the horizontal translation beam assembly 50 on the other hand, so the telescopic beam 31 should have sufficient structural rigidity. In this embodiment, the cross section of the telescopic beam 31 is L-shaped, and both ends of the horizontal translation beam assembly 50 are arranged on the horizontal part 311 of the L-shaped structure of the two telescopic beams 31.

[0075] The first lateral telescopic mechanism 40 is used to drive the translation beam assembly 30 to move laterally. The two ends of the first lateral telescopic mechanism 40 are connected with the support assembly 20 and the translation beam assembly 30 respectively, so as to drive the translation beam assembly 30 to move laterally relative to the support assembly 20. The first lateral telescopic mechanism 40 can adopt any linear displacement mechanism in the prior art, such as a hydraulic cylinder, an electric cylinder, an air cylinder, a ball screw driven by a motor, etc. The specific selection of the first lateral telescopic mechanism 40 is not limited in the present application.

[0076] In view of the complexity of the structure, the first lateral telescopic mechanism 40 in the embodiment adopts a hydraulic cylinder or an electric cylinder. The cylinder barrel of the hydraulic cylinder or the electric cylinder is fixedly connected with the first side beam 22, and the piston end is fixedly connected with the telescopic beam 31 through a mounting seat 41. More specifically, referring to Figure 3 , the mounting seat 41 is located at the outer end (cantilever end) of the railway side section 31a of the telescopic beam 31, so that the first lateral telescopic mechanism 40 is in a natural state (piston retracted state). The railway side section 31a of the telescopic beam 31 moves to be axially coincident with the first side beam 22, and the highway side section 31b of the telescopic beam 31 extends outward relative to the railway, so as to avoid the traction locomotive when the railway flat car is towed by the traction locomotive, and ensure the smooth passing of the traction locomotive.

[0077] The lateral translation beam assembly 50 is a mounting base of the spreader assembly 70. The lateral translation beam assembly 50 is movably mounted on the translation beam assembly 30, specifically, the lateral translation beam assembly 50 is movably mounted on the horizontal part 311 of the L-shaped structure of the two telescopic beams 31. In order to ensure the structural strength, the lateral translation beam assembly 50 includes two or more frame longitudinal beams 51, two or more second side beams 52 and two or more mounting platforms 53. Each frame longitudinal beam 51 is arranged longitudinally and parallel to each other. Each second side beam 52 is arranged laterally and parallel to each other. The frame longitudinal beams 51 and the second side beams 52 are connected to form a rectangular frame structure. The rectangular frame structure ensures that the spreader assembly 70 can still be stably translated without deformation after hoisting the container 200.

[0078] The second lateral telescopic mechanism 60 is used to drive the lateral translation beam assembly 50 to move laterally. The two ends of the second lateral telescopic mechanism 60 are connected with the translation beam assembly 30 and the lateral translation beam assembly 50 respectively, so as to drive the lateral translation beam assembly 50 to move laterally relative to the translation beam assembly 30. The second lateral telescopic mechanism 60 can adopt any linear displacement mechanism in the prior art, such as a hydraulic cylinder, an electric cylinder, an air cylinder, a ball screw driven by a motor, etc. The specific selection of the second lateral telescopic mechanism 60 is not limited in the present application.

[0079] Referring to Figure 5In the embodiment, the second transverse telescopic mechanism 60 adopts a roller 62 driven by a motor 61. The motor 61, a speed reducer 63, a shaft coupling 64 and the roller 62 are sequentially connected and transmit torque. A track 32 is arranged on the horizontal part 311 of the telescopic beam 31. The track 32 is arranged on the telescopic beam 31 in the transverse direction. The roller 62 rolls along the track 32 under the drive of the motor, thereby driving the entire drive transverse beam assembly 50 to move relative to the transverse beam assembly 30. For safety, two limiting stops 33 are arranged on the telescopic beam 31. The two limiting stops 33 are arranged at the two ends of the track 32, respectively, to prevent the roller 62 from leaving the track 32.

[0080] In order to facilitate the installation of the second transverse telescopic mechanism 60, in the embodiment, the transverse beam assembly 50 further comprises an installation platform 53. The second transverse telescopic mechanism 60 is installed on the installation platform 53. The installation platform 53 is fixed to the frame longitudinal beam 51. In order to ensure uniform stress, at least two second transverse telescopic mechanisms 60 should be arranged. For example, if two second transverse telescopic mechanisms 60 are arranged, the two second transverse telescopic mechanisms 60 are arranged at the two ends of the frame longitudinal beam 51. If four second transverse telescopic mechanisms 60 are arranged, the four second transverse telescopic mechanisms 60 are arranged at the two ends of the two frame longitudinal beams 51, respectively. Correspondingly, the number of installation platforms 53 should be the same as that of the second transverse telescopic mechanisms 60. Each second transverse telescopic mechanism 60 is installed on the corresponding installation platform 53.

[0081] The spreader assembly 70 is arranged on the transverse beam assembly 50 and is used for loading and unloading the container 200. Under the drive of the second transverse telescopic mechanism 60, the transverse beam assembly 50 drives the spreader assembly 70 to move in the transverse direction, so as to load and unload the container between the two sides of the transverse direction, i.e. between the railway flat car and the highway loading and unloading area, thereby achieving efficient transfer of the container 200 between the railway and the highway. The spreader assembly 70 is a mature prior art. The container spreader in the prior art can be adopted. The specific structure is not described here.

[0082] Considering that the installation position of the container 200 on the railway flat car has a certain deviation, in order to ensure that the spreader assembly 70 and the lock of the container 200 are successfully locked, the spreader assembly 70 is flexibly installed. For details, see Figure 6 A lifting lug 54 is arranged on the web plate 511 of the frame longitudinal beam 51. A shackle 55 is arranged on the lifting lug 54. The spreader assembly 70 is connected with the shackle 55 through a chain 56. Since the chain 56 and the shackle 55 and the chain 56 and the spreader assembly 70 are movable, it can be ensured that the spreader assembly 70 moves within a certain range, thereby facilitating the spreader assembly 70 and the lock of the container 200 to be successfully locked.

[0083] In addition, considering that the stopping position of the railway flat car for transporting the container and the stopping position of the container side hoisting and transferring system 100 can be deviated, in order to ensure that the spreader assembly 70 and the lock of the container 200 are successfully locked, the traversing beam assembly 50 further comprises one or more longitudinal telescopic mechanisms 90, and the two ends of the longitudinal telescopic mechanism 90 are respectively applied to the frame longitudinal beam 51 and the spreader assembly 70. The longitudinal telescopic mechanism 90 can adopt any linear displacement mechanism, such as a hydraulic cylinder, an electric cylinder, an air cylinder, a ball screw pair driven by a motor, etc., and the specific selection of the longitudinal telescopic mechanism 90 is not limited in the present application.

[0084] Specifically, referring to Figure 4 In the embodiment, the longitudinal telescopic mechanism 90 is provided with two groups, and the two groups of longitudinal telescopic mechanisms 90 are symmetrically distributed on the two sides of the spreader assembly 70 in the transverse direction. The longitudinal telescopic mechanism 90 comprises a telescopic cylinder 91, which can be a hydraulic cylinder / electric cylinder. The cylinder body of the telescopic cylinder 91 is fixed to the frame longitudinal beam 51, and the telescopic cylinders 91 in the two groups of longitudinal telescopic mechanisms 90 are arranged at an angle with the frame longitudinal beam 51. The piston of the telescopic cylinder 91 is connected to the longitudinal center of the spreader assembly 70 through a ball hinge. When the two telescopic cylinders 91 are extended and retracted, the horizontal angle of the spreader assembly 70 can be finely adjusted, so as to ensure that the spreader assembly 70 and the lock of the container 200 are successfully locked.

[0096] See also Figures 8 to 11 The working principle of the container side lifting and transfer system 100 of this embodiment is as follows:

[0097] A. Container unloading process;

[0098] A1. The container 200 on the railway flat car enters the railway loading and unloading area (Area A). During this process, the container side lifting and transfer system 100 is in the initial state. Figure 9 As shown, the piston of the first transverse telescopic mechanism 40 retracts, the railway-side segment 31a of the telescopic beam 31 moves to axially overlap with the first side beam 22, and the road-side segment 31b of the telescopic beam 31 extends outward toward the opposite side of the railway. At this point, the railway side of the container side lifting and transfer system 100 has no extending mechanisms, allowing it to avoid the traction locomotive and ensure smooth passage of the traction locomotive towing the railway flatcar.

[0099] A2. The railway flat car is parked in place, and the telescopic beam 31 is extended toward the railway side. The railway side section 31a of the telescopic beam 31 extends under the electrified railway network 300, and the road side section 31b is axially aligned with the first side beam 22. During the extension of the telescopic beam, the support legs 80 are in a retracted state, and the support legs 80 can pass through the gap between two adjacent containers. After the telescopic beam 31 is extended into place, the lifting legs 21 are lowered, and the spreader assembly 70 and the lock of the container 200 are automatically locked. Figure 10 shown.

[0100] A3, support leg 80 is extended to the pier column, then the lifting leg 21 and the support leg 80 are synchronously lifted, the spreader assembly 70 lifts the container 200, as shown. Figure 11

[0101] A4, the cross beam assembly 50 carries the container along the telescopic beam 31 to move horizontally in the axial direction, and the container 200 is transferred from the railway loading and unloading area (A area) to the highway loading and unloading area (B area), as shown. Figure 12

[0102] A5, the lifting leg 21 and the support leg 80 are synchronously lowered, and the container 200 is lowered to the truck in the highway loading and unloading area (B area).

[0103] B, the container loading process is the reverse process of the container unloading process, which is not expanded here.
