Description

Technical Field

[0001] This application relates to the field of railway unloading, and particularly to a device for receiving railway bulk cargoes. Background Art

[0002] Railway is an important mode of logistics transportation in China. Thanks to its strong carrying capacity, low cost and excellent safety, railway has become the main logistics mode for transporting large quantities of bulk cargoes such as grains, coal mines, and ores. Although railway logistics has great advantages in transportation, some railway freight yards have problems in the loading and unloading efficiency of goods due to factors such as narrow working sites and lack of working equipment. Therefore, improving the unloading operation process and enhancing the unloading efficiency have become top priorities in the field of railway logistics.

[0003] To solve the above problems, there are two traditional railway unloading methods; one is to use a large dumper for unloading. This device can unload the goods of one carriage at a time by flipping, with extremely high efficiency. However, building such a device requires not only a wide working site, but also the device is very expensive and difficult to maintain. Another unloading method is to use a unloading machine modified from an excavator, which is also the unloading method used by most small logistics freight yards. Taking the unloading process of bulk cargoes such as coal as an example: after the train enters the station yard, the workers open the carriage door and then use the unloading machine to directly scoop the coal through the opened door onto the ground, and then use a forklift to transport the coal on the ground to the truck and transport it away. However, due to the limitations of the platform site, the unloading machine often has to wait until the coal on the ground is cleared before unloading the next carriage. This not only has problems of low efficiency and complexity in the unloading operation process, but also is prone to safety accidents when multiple heavy machinery are used for manned operations on site, and may even cause casualties in severe cases.

The following combines Figures 1 to 11 to describe the railway bulk cargo receiving device in detail.

[0069] In some of the embodiments, a railway bulk cargo receiving device is applied to train unloading as Figure 1 shown. The railway bulk cargo receiving device includes a material conveying assembly 100, an angle adjusting assembly 200, a luffing drive assembly 300, and a multi-stage slide table assembly 400. The material conveying assembly 100 is used to convey railway bulk cargo; the angle adjusting assembly 200 is respectively connected to the material conveying assembly 100 and the multi-stage slide table assembly 400 for adjusting the inclination angle of the multi-stage slide table assembly 400 relative to the material conveying assembly 100; the luffing drive assembly 300 is connected to the multi-stage slide table assembly 400 for adjusting the overall length of the multi-stage slide table assembly 400. Combining Figure 2, the multi-stage sliding table assembly 400 includes at least two stages of sliding tables connected in sequence. Among them, the first-stage sliding table 401 is located on the material conveying assembly 100, and the third-stage sliding table 403 is used to match the unloading open door 600 of the carriage to receive the railway bulk cargo from the unloading open door 600 and transfer it to the material conveying assembly 100; the angle adjustment assembly 200 is respectively connected to the material conveying assembly 100 and the first-stage sliding table 401 for adjusting the inclination angle between the first-stage sliding table 401 and the material conveying assembly 100; combined with Figure 10 and Figure 11 , the luffing drive assembly 300 is respectively connected to each stage of the sliding table of the multi-stage sliding table assembly 400 for adjusting the overall length of the multi-stage sliding table assembly 400. With such a design, through the cooperation of the material conveying assembly 100, the angle adjustment assembly 200, the luffing drive assembly 300 and the multi-stage sliding table assembly 400, on the one hand, it can be applied to the railway platform unloading operation scenario, which can conveniently connect the bulk cargo unloaded by the train and convey it to other equipment through the conveyor, replacing manual material handling, saving labor costs, reducing the unloading operation process, improving the operation efficiency, and eliminating potential safety hazards; on the other hand, it can adjust the railway bulk cargo receiving device according to the height of the train unloading open door 600, so it has better applicability, making the railway bulk cargo receiving device not only applicable to a variety of bulk materials, but also capable of taking into account various special terrains and working in a variety of different working sites.

[0070] In some embodiments, as Figure 2 shown, the material conveying assembly 100 includes a belt conveyor 101 and a leakage-proof baffle 102 provided on one side of the belt conveyor 101; the first-stage sliding table 401 is located on the belt conveyor 101, and the angle adjustment assembly 200 is used to adjust the inclination angle between the first-stage sliding table 401 and the belt conveyor 101. As an example, the material conveying assembly 100 further includes a moving device provided under the belt conveyor 101. With such a design, on the one hand, the efficient conveying of bulk cargo is realized through the belt conveyor 101, and the leakage-proof baffle 102 can effectively prevent the material from leaking during the conveying process, reducing waste and cleaning costs. On the other hand, the setting of the angle adjustment assembly 200 in cooperation with the first-stage sliding table 401 enables the first-stage sliding table 401 to flexibly adjust the inclination angle according to the height of the carriage unloading open door 600, improving the adaptability and flexibility of the device. On the other hand, the setting of the moving device enhances the mobility of the material conveying assembly 100, enabling it to move more conveniently between different working sites, further improving the practicality and operation efficiency of the entire railway bulk cargo receiving device.

[0071] In some embodiments, as Figure 2As shown, at least one second-stage slide 402 is provided between the first-stage slide 401 and the third-stage slide 403 of the multi-stage slide assembly 400. In combination with Figure 10 , a second-stage slide 402 is provided between the first-stage slide 401 and the third-stage slide 403 of the multi-stage slide assembly 400. In other embodiments, exemplarily, the number of the second-stage slides 402 is at least two, and the specifications of the second-stage slides 402 are the same or different. In combination with Figure 11 , the luffing drive assembly 300 adjusts the overall length of the multi-stage slide assembly 400 to the shortest state for easy storage. Such a design enables the multi-stage slide assembly 400 to flexibly adjust the overall length according to the height of the carriage unloading open door 600 and the working site conditions, further improving the applicability and adaptability of the device. At the same time, the multi-stage structure of the multi-stage slide assembly 400 can better receive the bulk cargo from the unloading open door 600 at different heights and distances, avoiding cargo accumulation or overflow, thereby improving the stability and safety of the unloading operation.

[0072] Exemplarily, as Figure 6 and Figure 7As shown, the second-stage sliding table 402 includes a second load-bearing frame 402a, a second material receiving plate 402b, a guide rail support seat 402c, a first guide rail 402d, a second pulley 402e, a first tie point 402f, and a second guide block 402g; the second material receiving plate 402b, the guide rail support seat 402c, and the first guide rail 402d are all arranged on the second load-bearing frame 402a, and the first guide rail 402d is also on the guide rail support seat 402c. The first guide rail 402d cooperates with the first guide block 401f for sliding guidance, so that the second-stage sliding table 402 or its second load-bearing frame 402a is slidably arranged on the first-stage sliding table 401; the second pulley 402e and the first tie point 402f are both arranged under the second load-bearing frame 402a, and are respectively used to connect the steel cables of the luffing drive assembly 300. The second guide block 402g is arranged on the second material receiving plate 402b and is used to cooperate with and install another sliding table, such as a third-stage sliding table 403 or another second-stage sliding table 402. Such a design enables the second-stage sliding table 402 to achieve smooth sliding through the cooperation of the first guide rail 402d and the first guide block 401f, and thus can flexibly adjust its position under the action of the luffing drive assembly 300 to adapt to different heights of the discharge hopper 600 and working site conditions. At the same time, the settings of the second pulley 402e and the first tie point 402f can ensure the stable connection and transmission of the steel cables, guaranteeing the movement reliability of the sliding table. In addition, the design of the second guide block 402g facilitates the cooperation and installation with other sliding tables, further enhancing the modularity and length scalability of the multi-stage sliding table assembly 400, and improving the overall performance and applicability of the railway bulk loading and unloading material receiving device.

[0073] In some embodiments, as Figure 1 shown, the third-stage sliding table 403 is used to be arranged under the discharge hopper 600. In other embodiments, the third-stage sliding table 403 is used to be connected to the discharge hopper 600. Combining Figure 8 and Figure 9, by way of example, based on the structure of the second - stage slide 402, the third - stage slide 403 additionally adds a second attachment point 403d; or the number and position of the second attachment point 403d of the third - stage slide 403 are set differently from those of the first attachment point 402f of the second - stage slide 402. Exemplarily, the third - stage slide 403 includes a third load - bearing frame 403a, a third receiving plate 403b, a second guide rail 403c, and a second attachment point 403d; the third receiving plate 403b and the second guide rail 403c are both disposed on the third load - bearing frame 403a, and the second guide rail 403c cooperates with the second guide block 402g to serve as a sliding guide, so that the third - stage slide 403 or its third load - bearing frame 403a is slidably disposed on the second - stage slide 402; the second attachment point 403d is disposed under the third load - bearing frame 403a and is used to connect the steel cable of the luffing drive assembly 300. With such a design, on the one hand, the third - stage slide 403 adds a second attachment point 403d on the basis of the second - stage slide 402, further enhancing the structural expandability of the multi - stage slide assembly. By setting different numbers and positions of attachment points, the connection method and movement range between the slides can be adjusted more flexibly to adapt to the carriage unloading open doors 600 at different heights and positions. On the other hand, the cooperation between the second guide rail 403c and the second guide block 402g provides a stable sliding guide for the third - stage slide 403. This design ensures the smooth movement of the slide under the action of the luffing drive assembly 300, avoiding jamming or deviation during the sliding process, thereby improving the overall stability and reliability of the device. On the one hand again, the third load - bearing frame 403a and the third receiving plate 403b of the third - stage slide 403 can directly receive the bulk cargo from the carriage unloading open door 600 and transfer it smoothly to the next - stage slide or the material conveying assembly 100. By optimizing the structure and layout of the slide, the cargo weight can be more effectively dispersed, avoiding cargo accumulation or overflow, and further improving the efficiency and safety of the unloading operation. On the one hand also, by adding a second attachment point 403d and optimizing the slide structure, the third - stage slide 403 can better adapt to complex operating environments, such as carriages at different heights, uneven unloading sites, etc. This design enables the railway bulk cargo receiving device to operate efficiently in a variety of different scenarios, enhancing its versatility and practicality.

[0074] As an example, the luffing drive assembly 300 is provided with a steel cable. The luffing drive assembly 300 is connected to the first-stage slide 401, and the luffing drive assembly 300 is connected to the other slides of the multi-stage slide assembly 400 except the first-stage slide 401 through the steel cable. That is, the luffing drive assembly 300 pulls the other slides of the multi-stage slide assembly 400 through the steel cable. As an example, the luffing drive assembly 300 includes a pulley block and a steel cable installed on the pulley block. The pulley block is connected to the first-stage slide 401 and is connected to the other slides of the multi-stage slide assembly 400 except the first-stage slide 401 through the steel cable. With such a design, by utilizing the mechanical advantages of the steel cable and the pulley block, the overall length of the multi-stage slide assembly 400 can be efficiently adjusted to adapt to the carriage discharge open door 600 at different heights, ensuring the stability and flexibility of the slide assembly. By pulling each slide through the steel cable, precise length adjustment can be achieved, while reducing the friction and wear of mechanical components, improving the drive efficiency and the service life of the device.

[0075] Exemplarily, as Figure 4 shown, the luffing drive assembly 300 includes a fixed frame 301, a power member 302 installed on the fixed frame 301, a double winch 303 installed on the power member 302 for winding the steel cable, a third bearing block 304 for fixing the power member 302, and a support plate 305 fixedly connected to the third bearing block 304. The double winch 303 includes a single winch, two winches, multiple winches, a set of winches, etc., and is designed according to the number of slides of the multi-stage slide assembly 400. With such a design, the fixed frame 301 and the support plate 305 provide a stable installation foundation, ensuring the stability and reliability of the entire luffing drive assembly 300. The cooperation between the power member 302 and the double winch 303 can efficiently wind the steel cable, achieving precise control of the multi-stage slide assembly 400, so as to flexibly adjust the length of the slide to adapt to the discharge requirements at different heights. At the same time, the setting of the third bearing block 304 effectively reduces the friction and wear of the power member 302 during operation, improving the durability and service life of the assembly.

[0076] Exemplarily, the fixed frame 301 is fixedly arranged on the first-stage slide 401, as Figure 4As shown, the power component 302 includes a reduction motor 302a fixedly installed inside the fixed frame 301, a coupling 302b fixedly connected to the output end of the reduction motor 302a, and a drive shaft 302c fixedly connected to the coupling 302b. The double winch 303 is arranged on the drive shaft 302c; the reduction motor 302a drives the drive shaft 302c to rotate through the coupling 302b; the drive shaft 302c passes through the third bearing block 304, and the third bearing block 304 is axially connected to the drive shaft 302c to play a supporting role. The third bearing block 304 is fixed to the fixed frame 301 through the support plate 305. Such a design, on the one hand, enables the luffing drive assembly 300 to stably provide power. Through the cooperation of the reduction motor 302a, the coupling 302b and the drive shaft 302c, precise control of the double winch 303 is achieved, so as to efficiently wind the steel cable and adjust the length of the multi-stage slide assembly 400. On the other hand, the setting of the third bearing block 304 and the support plate 305 enhances the stability of the drive shaft 302c, reduces vibration and wear during operation, improves the efficiency of power transmission and the service life of the component, and ensures the reliability and durability of the entire railway bulk cargo receiving device in a complex operating environment.

The first load-bearing frame 401a is adjusted in angle relative to the belt conveyor 101 of the material conveying assembly 100 through the cooperation of the support member 202 and the crank and connecting rod member 203, and the luffing drive assembly 300 is installed on the fixing angle steel 401c through its own fixing frame 301; the first material receiving plate 401d is arranged on the first load-bearing frame 401a, and the first pulley 401e is arranged under the first material receiving plate 401d or under the first load-bearing frame 401a for connecting the steel cable of the luffing drive assembly 300, and the first guide block 401f is arranged on the first material receiving plate 401d for cooperatively installing another sliding table such as the third-stage sliding table 403 or the second-stage sliding table 402. Such a design, on the one hand, enables the first-stage sliding table 401 to flexibly adjust the tilt angle through the angle adjustment assembly 200 to adapt to the unloading open doors 600 of carriages at different heights, and to precisely control the multi-stage sliding table assembly 400 through the luffing drive assembly 300. On the other hand, the first load-bearing frame 401a provides a stable support foundation to ensure the stability and reliability of the sliding table assembly when carrying goods. The arrangement of the first pulley 401e and the first guide block 401f enhances the connection and sliding guiding functions between the sliding tables, improving the flexibility and adaptability of the railway bulk loading and unloading material receiving device. On the other hand, the fixing angle steel 401c provides a reliable fixing point for the installation of the luffing drive assembly 300, thus ensuring the stable operation of the luffing drive assembly 300.

[0078] In some embodiments, such as Figure 3As shown, the angle adjustment assembly 200 includes a bracket 201, a support member 202, a crank and connecting rod member 203, and a driving member 204; the bracket 201 is detachably connected to the material conveying assembly 100 or the belt conveyor 101 of the material conveying assembly 100; the support member 202 is disposed on the bracket 201 and is rotatably connected to the first-stage slide 401; the crank and connecting rod member 203 is rotatably disposed on the bracket 201 and is rotatably connected to the first-stage slide 401; the driving member 204 is disposed on the bracket 201 and is drivingly connected to the crank and connecting rod member 203 for adjusting the relative distance between the crank and connecting rod member 203 and the support member 202 to adjust the inclination angle of the first-stage slide 401 with respect to the material conveying assembly 100. With such a design, on the one hand, the driving member 204 precisely controls the movement of the crank and connecting rod member 203, thereby flexibly adjusting the inclination angle of the first-stage slide 401 to adapt to the unloading open doors 600 of carriages at different heights. On the other hand, the detachable connection method of the bracket 201 enhances the portability and versatility of the assembly, facilitating quick installation and disassembly on different devices. On yet another hand, the rotatable connections of the support member 202 and the crank and connecting rod member 203 ensure the smoothness and stability of the angle adjustment, improving the reliability and safety of the railway bulk cargo receiving device during operation.

[0079] In some embodiments, such as Figure 3As shown, the support member 202 includes a first support member and a second support member. The first support member is fixedly connected to the bracket 201 through a fixed channel steel 202a. The crank-link member 203 is rotatably connected to the first-stage slide 401 through the second support member. In some embodiments, the support member 202 includes a first bearing seat 202b, a bearing member 202c, and a second bearing seat 202d. The first bearing seat 202b is directly disposed on the bracket 201, or disposed on the bracket 201 through the fixed channel steel 202a, or disposed on the bracket 201 through the crank-link member 203. The bearing member 202c passes through the first bearing seat 202b and is in bearing fit with the first bearing seat 202b. The bearing member 202c also passes through the second bearing seat 202d and is fixed to the second bearing seat 202d. The second bearing seat 202d is connected to the first-stage slide 401. As an example, the bearing member 202c is a solid round steel. In specific applications, it can also be understood that the fixed channel steel 202a is a part of the first support member, that is, the first support member includes the fixed channel steel 202a, the first bearing seat 202b, the bearing member 202c, and the second bearing seat 202d. Such a design, on the one hand, through the cooperation between the bearing member 202c and the bearing seat, realizes the reliable connection and flexible rotation between the support member 202 and the first-stage slide 401, ensuring the smoothness and accuracy of angle adjustment. On the other hand, the setting of the first bearing seat 202b and the second bearing seat 202d enhances the structural stability, and the use of solid round steel improves the strength and durability of the bearing member 202c, extending the service life of the component. On the further hand, the use of the fixed channel steel 202a provides additional fixation and support for the support member 202, further improving the stability and reliability of the entire angle adjustment assembly 200. On the yet further hand, the structures of the first support member and the second support member are the same or similar, which is beneficial to production and manufacturing, saving the preparation process and the material preparation cost.

[0080] In some embodiments, such as Figure 3As shown, the crank connecting rod member 203 includes a bearing joint 203a, a first connecting rod 203b, and a second connecting rod 203c; the bearing joint 203a is rotatably connected to the first-stage slide 401 through the second support member; the second connecting rod 203c is rotatably arranged on the bracket 201 and is connected to the fixed end of the bearing joint 203a through the first connecting rod 203b; the driving member 204 is drivingly connected to the second connecting rod 203c to drive the second connecting rod 203c to rotate on the bracket 201. In some embodiments, the bearing joint 203a is axially matched with the bearing member 202c of the second support member; the second connecting rod 203c is rotationally matched with the first connecting rod 203b through a pin shaft. Such a design, on the one hand, enables the angle adjustment assembly 200 to precisely control the rotation of the second connecting rod 203c through the driving member 204, and then drives the entire crank connecting rod member 203 to move, realizing flexible adjustment of the tilt angle of the first-stage slide 401. On the other hand, the rotatable connection between the bearing joint 203a and the first-stage slide 401 makes the angle adjustment easy to achieve and ensures the smoothness and stability of the adjustment process, while the cooperation of the first connecting rod 203b and the second connecting rod 203c enhances the compactness and reliability of the structure. On the one hand, this structure not only improves the accuracy of angle adjustment but also ensures the stability and durability of the railway bulk loading and unloading goods receiving device under different operating conditions.

[0081] In some embodiments, such as Figure 3 and Figure 11As shown, the angle adjustment assembly 200 further includes a limiting member 205. The limiting member 205 is disposed on the bracket 201 and is used to limit the extreme value of the tilt angle. Exemplarily, the limiting member 205 includes a limiting seat 205a, a limiting column 205b connected to the bearing member 202c of the support member 202, and a magnetic limit switch 205c disposed on the limiting seat 205a. Exemplarily, the number of magnetic limit switches 205c is two, and the two magnetic limit switches 205c are respectively fixedly installed on both sides of the limiting seat 205a. Exemplarily, the limiting seat 205a is semicircularly installed on the bracket 201 or on a steel plate welded to the front end of the bracket. The limiting column 205b rotates as the bearing member 202c of the support member 202 rotates. The magnetic limit switch 205c is used to detect the position of the limiting column 205b, and issues a limit signal when the position of the limiting column 205b exceeds a preset position, or controls the driving member 204 to stop driving the crank connecting rod member 203 to limit the extreme value of the tilt angle. Such a design, on the one hand, effectively prevents the tilt angle of the first-stage slide 401 from being too large or too small through the limiting member 205, thereby avoiding equipment damage or improper unloading of goods. On the other hand, the cooperation of the limiting seat 205a and the limiting column 205b, combined with the automatic detection function of the magnetic limit switch 205c, ensures the safety and reliability of the angle adjustment. On the other hand, this limiting protection mechanism improves the automation level of the railway bulk loading and unloading goods receiving device, protects the first-stage slide 401 and the material conveying assembly 100, and reduces the need for manual intervention, thereby further improving the operation efficiency and safety.

[0082] In some embodiments, as Figure 3 shown, the driving member 204 includes a driving motor 204a and a fixing seat 204b. The driving motor 204a is disposed on the fixing seat 204b and is drivingly connected to the crank connecting rod member 203 or the second connecting rod 203c of the crank connecting rod member 203. The fixing seat 204b is disposed on the bracket 201. Such a design, on the one hand, enables the driving member 204 to stably provide power and accurately control the movement of the crank connecting rod member 203 through the driving motor 204a, thereby realizing accurate adjustment of the tilt angle of the first-stage slide 401. On the other hand, the setting of the fixing seat 204b enhances the installation stability of the driving motor 204a and ensures the reliability and accuracy of power transmission during the adjustment process. On the other hand, this structural design facilitates the maintenance and replacement of the driving motor 204a, thereby improving the maintainability and service life of the railway bulk loading and unloading goods receiving device.

[0108] As Figures 1 to 4 shown, based on Embodiment 1, on this basis, the fixing frame 301 is fixedly arranged on the first-stage slide 401, and the power member 302 is fixedly installed inside the fixing frame 301; the power member 302 includes a reduction motor 302a fixedly installed inside the fixing frame 301, a coupling 302b fixedly connected to the output end of the reduction motor 302a, and a drive shaft 302c fixedly connected to the coupling 302b. A double winch 303 is arranged on the drive shaft 302c; the reduction motor 302a drives the drive shaft 302c to rotate through the coupling 302b; the third bearing seats 304 fix both ends of the drive shaft 302c to play a supporting role, and the support plate 305 is fixed to the fixing frame 301 of the whole device. The double winch is composed of two winches combined together. One winch is responsible for winding and contracting the steel cable of the slide, which is called the contraction steel cable, and the other winch is responsible for winding and unwinding the steel cable of the slide, which is called the extension steel cable. The third bearing seats 304 fix both ends of the drive shaft 302c to play a supporting role, and the support plate 305 is fixed to the fixing frame 301 of the whole device. The support plate 305 is fixed to the fixing frame 301 of the whole device. As an example, the third bearing seat 304 is installed on the support plate 305.

[0109] As an example, the first-stage slide 401 further includes a first load-bearing frame 401a fixedly connected to the bearing joint 203a, a shaft seat fixing bracket 401b, a fixing angle steel 401c, a first material receiving plate 401d, a first pulley 401e, and a first guide block 401f; the shaft seat fixing bracket 401b and the fixing angle steel 401c are both welded and fixed to the first load-bearing frame 401a. The bearing seats included in the support member 202 and the crank-link member 203 are respectively installed on the shaft seat fixing bracket 401b and the first load-bearing frame 401a. The first load-bearing frame 401a adjusts the angle through the cooperation of the support member 202 and the crank-link member 203, and the amplitude-variable drive assembly 300 for overall material receiving is installed on the fixing angle steel 401c through the fixing bracket 301; the first material receiving plate 401d is also installed on the first load-bearing frame 401a by spot welding to enhance its load-bearing capacity. The first pulley 401e is installed at the center of the top end of the first-stage slide 401 for fixing the steel cable, and the first guide block 401f is fixed inside both sides of the first material receiving plate 401d for installing and cooperating with the second-stage slide 402.

[0110] As an example, the second-stage slide 402 includes a second load-bearing frame 402a, a second material receiving plate 402b, a guide rail support seat 402c, a first guide rail 402d, a second pulley 402e, a first cable fixing point 402f, and a second guide block 402g; the second material receiving plate 402b, the guide rail support seat 402c, and the first guide rail 402d are all fixed to the second load-bearing frame 402a. The second material receiving plate 402b is installed on the second load-bearing frame 402a by spot welding to enhance its load-bearing capacity, and the main function of the guide rail support seat 402c is to enhance the strength of the first guide rail 402d by supporting it. The first guide rail 402d is fixed to both the second load-bearing frame 402a and the guide rail support seat 402c by welding, and cooperates with the first guide block 401f to play a sliding guiding role, enabling the second-stage slide 402 to slide up and down within the first-stage slide 401; a second pulley 402e is installed at each of the four end corners of the second-stage slide 402 for fixing the steel cable. The first cable fixing point 402f, which is also used for fixing the steel cable, is installed at the center of the top end of the bottom of the second-stage slide 402, and the second guide block 402g is fixed inside both sides of the second material receiving plate 402b for installing and cooperating with the third-stage slide 403.

[0111] As an example, the third-stage slide 403 further includes a third load-bearing frame 403a, a third receiving plate 403b, a second guide rail 403c, and a second attachment point 403d. As an example, the third-stage slide 403 is similar in structure to the second-stage slide 402, except that the position of the second attachment point 403d for fixing the steel cable is different. There is one second attachment point 403d on each outer side of the tail end of the third-stage slide 403. The main structure of the third-stage slide 403, including the third load-bearing frame 403a, the third receiving plate 403b, and the second guide rail 403c, is similar to that of the second-stage slide 402 in terms of the fixing method and functional role.

[0112] The luffing drive of the luffing drive assembly 300 includes two drive processes: extension and contraction. The drive member 302 and the double winch 303 are the core components of the entire device. When the reduction motor 302a rotates forward, it drives the double winch 303 on the drive shaft 302c to rotate forward. At this time, while the extension steel cable wound around one of the winches is being wound, it pulls the second-stage slide 402 forward. The contraction steel cable wound in the opposite direction on the other winch starts to be released synchronously to avoid conflicts. This is the drive process for the deployment of the multi-stage slide assembly 400. When the reduction motor 302a rotates in reverse, it drives the double winch 303 on the drive shaft 302c to rotate in reverse. At this time, while the contraction steel cable wound around one of the winches is being wound, it pulls the second-stage slide 402 backward. The extension steel cable wound in the forward direction on the other winch starts to be released synchronously to avoid conflicts. This is the drive process for the contraction of the multi-stage slide assembly 400.

[0113] During use, such as Figure 2 and Figure 10In the illustrated embodiment, when the multi-stage sliding table assembly 400 is fully deployed for operation, it has three stages in total. In the retracted state, it is approximately equivalent to the length of the first-stage sliding table 401, greatly saving space. During the deployment process of the multi-stage sliding table assembly 400, the luffing drive assembly 300 fixed under the first-stage sliding table 401 winds and extends the steel cable. The extended steel cable passes through the first pulley 401e in the middle of the top of the first-stage sliding table 401 and is fixed to the middle of the tail of the second-stage sliding table 402. The extended steel cable during the winding process pulls the second-stage sliding table 402 to slide forward through the first pulley 401e fixed on the first-stage sliding table 401. During the retraction process, the luffing drive assembly 300 rotates in the reverse direction to wind the retraction steel cable fixed to the first attachment point 402f to pull the second-stage sliding table 402 to slide back. At this time, the second-stage sliding table 402 completes the sliding process of the second-stage sliding table relative to the first-stage sliding table through the first guide rails 402d externally installed on both sides and the first guide blocks 401f internally installed on both sides of the first-stage sliding table 401. Meanwhile, there are two sets of steel cables for driving the third-stage sliding table 403. One end of one set of steel cables is fixed inside the first guide block 401f of the first-stage sliding table, bypasses the second pulley 402e at the top of the side of the second-stage sliding table 402, and the other end is fixed to the outside of both sides of the tail end of the third-stage sliding table 403 for driving the extension of the third-stage sliding table 403. The other set of steel cables has one end fixed inside the guide block 401f of the first-stage sliding table, bypasses the second pulley 402e at the tail end of the side of the second-stage sliding table 402, and the other end is fixed to the outside of both sides of the tail end of the third-stage sliding table 403 for driving the retraction of the third-stage sliding table 403. When the second-stage sliding table 402 extends forward, based on the principle that the length of the steel cable of the driving pulley group remains unchanged, the second pulley 402e at the top of the second-stage sliding table 402 pulls the third-stage sliding table 403 to extend forward. At this time, the third-stage sliding table 403 completes the sliding process of the third-stage sliding table relative to the second-stage sliding table 402 through the second guide rails 403c externally installed on both sides and the second guide blocks 402g internally installed on both sides of the second-stage sliding table. Similarly, when the second-stage sliding table 402 retracts, based on the principle that the length of the steel cable of the driving pulley group remains unchanged, the second pulley 402e at the tail end of the second-stage sliding table 402 pulls the third-stage sliding table 403 to retract backward. In this way, the multi-stage sliding table assembly can quickly complete the extension and retraction operation process through the cooperation between the simple pulley group structure and the guiding mechanism, adapt to different working occasions, and is very convenient.
