Description

Technical Field

[0001] The present invention relates to the technical field of truck assembly, and more particularly to a lifting and fixing device for the front station board of a truck. Background Art

[0002] The truck bed generally consists of a bottom plate, left and right side plates, a front station board, and a rear board. The front station board is close to the vehicle head, and the left and right side plates and the rear board can generally be opened when necessary. When installing, the front station board is installed first.

[0003] Currently, when installing the front station board, it is mainly lifted by a hook controlled by a robotic arm that hooks the edge of the hook groove on the outside of the front board, and the stability is extremely poor. Summary of the Invention

[0004] To make up for the above deficiencies, the present invention provides a lifting and fixing device for the front station board of a truck, aiming to improve the extremely poor stability during the lifting process when installing the front station board currently.

[0005] The present invention is implemented as follows:

[0006] The present invention provides a lifting and fixing device for the front station board of a truck, including a base assembly and a lifting assembly.

[0007] The base assembly includes a bottom plate and a front station board. The front station board is arranged on one side of the bottom plate, and a hook groove is formed on the outside of the front station board.

[0008] The lifting assembly includes a robotic arm, a first frame, a first driving member, a first bidirectional lead screw, a first threaded sleeve, a first fixing rod, a first clamping plate, a second fixing rod, and a second clamping plate. The first frame is fixed on the robotic arm, the first driving member is installed on the first frame, the end of the output shaft of the first driving member penetrates through the end of the first frame and is connected to one end of the first bidirectional lead screw through a coupling. Both of the first threaded sleeves are threadedly connected to the first bidirectional lead screw. The first clamping plate is fixedly connected to the first threaded sleeve through the first fixing rod, and the second clamping plate is fixedly connected to the other first threaded sleeve through the second fixing rod.

[0009] In one embodiment of the present invention, a first sliding groove is formed through the bottom of the first frame, and the first fixing rod is slidably arranged in the first sliding groove.

[0010] In one embodiment of the present invention, a second sliding groove is formed through the bottom of the first frame, and the second fixing rod is slidably arranged in the second sliding groove.

[0011] In an embodiment of the present invention, the first clamping plate includes a first plate body and a first side roller. The first plate body is fixed to the bottom end of the first fixing rod, and the first side roller is rotatably arranged on one side of the first plate body.

[0012] In an embodiment of the present invention, at least two groups of the first side rollers are provided, and the two groups of the first side rollers are symmetrically arranged on the first plate body.

[0013] In an embodiment of the present invention, the first clamping plate further includes an upper roller, and the upper roller is rotatably arranged on the top of the first plate body.

[0014] In an embodiment of the present invention, at least two upper rollers are provided, and the two upper rollers are symmetrically arranged on the first plate body.

[0015] In an embodiment of the present invention, the second clamping plate includes a second plate body and a second side roller. The second plate body is fixed to the bottom end of the second fixing rod, and the second side roller is rotatably arranged on the second plate body.

[0016] In an embodiment of the present invention, at least two groups of the second side rollers are provided, and the two groups of the second side rollers are symmetrically arranged on the second plate body.

[0017] In an embodiment of the present invention, the second side rollers and the first side rollers are arranged in one-to-one correspondence.

[0018] In the related art, due to the relatively large self-weight of the front station board, it is only limited and fixed by the transverse clamping structure arranged at the top, and the stability is poor. If the manipulator moves at a relatively fast speed during the hoisting process or the front station board collides with the bottom board, the front station board is likely to break away from the hoisting assembly, which affects the installation efficiency of the front station board on the one hand and may pose a threat to the personal safety of the installation personnel on the other hand.

[0019] The truck front station board hoisting and fixing device provided by the present invention further includes an auxiliary fixing assembly. The auxiliary fixing assembly includes a first sleeve, a first sliding rod, a second sleeve, a second sliding rod, a spring, a pressing plate and a connecting rod. The first sleeve is fixed on the first frame body, the first sliding rod is slidably connected to the first sleeve, the second sleeve is fixed to the bottom end of the second sliding rod, the top end of the second sliding rod is connected to the inner wall of the second sleeve through the spring, the pressing plate is fixed to the bottom end of the second sliding rod, and both ends of the connecting rod are rotatably connected to the first fixing rod and the outer wall of the second sleeve respectively.

[0020] When the device is in use, the front station board is clamped by the hoisting assembly. During the process of the first clamping plate and the second clamping plate moving towards the front station board, the connecting rod will also drive the second sleeve to move downward. Then, the spring drives the connecting rod and the pressing plate fixed at the bottom end of the connecting rod to move downward, pressing the top of the front station board from above. At this time, the spring is in a compressed state, cooperating with the first clamping plate to complete the longitudinal clamping of the front station board, further improving the stability of the hoisting process. When the robotic arm moves upward, the front station board slides down a small distance. The top of the first clamping plate abuts against the top inside the hook groove, and the spring slightly elongates but is still in a pressed state, so that the pressing plate maintains the downward pressure on the front station board. With the above solution, while the hoisting assembly clamps the front station board horizontally, it can drive the auxiliary fixing assembly to apply pressure to the front station board from above, cooperating with the first clamping plate to complete the longitudinal clamping work of the front station board, further improving the stability of the hoisting process, ensuring the personal safety of the installation personnel, and indirectly improving the installation efficiency of the front station board.

[0021] In an embodiment of the present invention, the pressing plate includes a third plate body and a lower roller. The third plate body is fixed at the bottom end of the second sliding rod, and the lower roller is rotatably arranged on the third plate body.

[0022] In an embodiment of the present invention, at least two groups of the lower rollers are provided, and the two groups of the lower rollers are symmetrically arranged on the third plate body.

[0023] For the final fixing work of the front station board, the primary problem is the positioning of the front station board. In the related art, it is difficult for the hoisting assembly to finely adjust the position of the front station board accurately. Generally, it relies on manual assistance for positioning, and often requires a long time for multiple adjustments to accurately position, with low efficiency. Moreover, due to the large self-weight of the front station board, even a small movement of the front station board during the positioning process is likely to cause bumps and injuries to the installation personnel, and the personal safety of the installation personnel cannot be guaranteed.

[0024] The hoisting and fixing device for the front station board of the truck provided by the present invention further includes a positioning component. The positioning component includes a sliding connecting piece, a second frame body, a second driving piece, a second bidirectional lead screw, a second threaded sleeve, a fixing frame, a first positioning plate and a second positioning plate. The sliding connecting piece includes a third fixing rod, a third frame body, a guiding rod, a sliding sleeve and a fourth fixing rod. The third frame body is fixedly connected to the first fixing rod through the third fixing rod. The guiding rod is arranged on the third frame body. The sliding sleeve is slidably sleeved on the guiding rod. The top of the second frame body is fixedly connected to the sliding sleeve through the fourth fixing rod. The second driving piece is installed on the second frame body. The end of the output shaft of the second driving piece penetrates through the end of the second frame body and is connected to one end of the second bidirectional lead screw through a coupling. Both of the second threaded sleeves are threadedly connected to the second bidirectional lead screw. The first positioning plate is fixedly connected to the second threaded sleeve through the fixing frame. The second positioning plate is fixed on the fixing frame.

[0025] When the device is in use, the front station board is hoisted above the bottom plate by the hoisting component, and the front station board is horizontally moved until the second positioning plate contacts the end of the bottom plate. Then, the mechanical arm drives the front station board to move downwards so that its bottom contacts the upper surface of the bottom plate. The second driving piece is started. The output shaft of the second driving piece rotates to drive the second bidirectional lead screw to rotate. The two second threaded sleeves drive the two first positioning plates to approach each other, applying a lateral thrust to the front station board and driving the front station board to translate. Due to the setting of the sliding connecting piece, when the positioning component is stressed, the sliding sleeve can drive the components fixed to the sliding sleeve to have a relative displacement with the hoisting component. When one of the first positioning plates contacts the side of the front station board that exceeds the edge of the bottom plate, due to the large self-weight of the front station board, this first positioning plate remains relatively stationary with respect to the front station board and the bottom plate, while the positioning component is still in working state. Subsequently, the sliding sleeve slides on the guiding rod towards this first positioning plate. The other first positioning plate continues to move until it contacts the edge of the bottom plate. Since the bottom plate is in a fixed connection state with the external structure, this first positioning plate remains relatively stationary with respect to the bottom plate. Subsequently, the sliding sleeve slides on the guiding rod towards this first positioning plate, so that the first positioning plate in contact with the front station board starts to apply a thrust to the side of the front station board that exceeds the edge of the bottom plate, driving the front station board to move until the two side edges of the front station board are aligned with the two side edges of the bottom plate. At this time, the installer can start the installation work and establish the connection between the front station board and the bottom plate. With the above scheme, the accurate positioning of the front station board can be automatically completed, ignoring the positional relationship between the positioning component and the bottom plate and the front station board. The center line of the positioning component does not need to be in the same vertical plane as the center line of either of them. During the installation process, there is no need for manual displacement and adjustment of the position of the front station board, greatly improving the installation efficiency and installation effect, saving human resources, and ensuring the personal safety of the installer.

[0026] In an embodiment of the present invention, a third sliding groove is formed on the second frame body, and the fixing frame is slidably arranged in the third sliding groove.

[0027] The beneficial effects of the present invention are as follows: The hoisting and fixing device for the front station board of the freight car obtained by the above design of the present invention, when in use, controls the robotic arm through the hoisting instrument to drive the entire hoisting assembly to move above the front station board, so that the front station board is located between the first clamping plate and the second clamping plate, and the first clamping plate and the second clamping plate are at the hook groove in the center of the top of the front station board. Start the first driving member, the output shaft of the first driving member rotates to drive the first bidirectional lead screw to rotate, and the two first threaded sleeves approach each other. Through the first fixing rod and the second fixing rod, the first clamping plate and the second clamping plate connected below are driven to clamp the front station board, that is, the horizontal clamping of the front station board is completed. Control the robotic arm to move upward, and the front station board slides down a short distance so that the top of the first clamping plate contacts the top inner wall of the hook groove. Then, lift the front station board to near the installation point on the bottom plate through the robotic arm; adopting the above scheme, the front station board can be stably clamped on both sides, improving the stability during the hoisting process.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0039] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the present invention claimed, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0040] Embodiment

[0041] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a hoisting and fixing device for the front station plate of a freight truck includes a basic component 100 and a hoisting component 200. The hoisting machine uses the hoisting component 200 to hoist the front station plate 120 onto the bottom plate 110, and the hoisting component 200 is used to limit the front station plate 120 to maintain the moving stability of the front station plate 120 during hoisting.

[0042] Please refer to Figure 3 , the basic component 100 includes a bottom plate 110 and a front station plate 120. The front station plate 120 is arranged on one side of the bottom plate 110. A hook groove 130 is opened on the outer side of the front station plate 120. By opening the hook groove 130, on the one hand, the quality can be reduced while maintaining the strength of the front station plate 120, and on the other hand, it is convenient for the hoisting device to establish a connection with the front station plate 120.

[0043] Please refer to Figure 3 and Figure 4 , the hoisting component 200 includes a robotic arm 210, a first frame 220, a first driving member 230, a first double - lead screw 240, a first threaded sleeve 250, a first fixing rod 260, a first clamping plate 270, a second fixing rod 280 and a second clamping plate 290. The robotic arm 210 is connected to an external hoisting device, and the hoisting device can control the movement of the robotic arm 210. The first frame 220 is fixed on the robotic arm 210. The first driving member 230 is installed on the first frame 220. The first driving member 230 is a motor. The end of the output shaft of the first driving member 230 penetrates through the end of the first frame 220 and is connected to one end of the first double - lead screw 240 through a coupling. Both first threaded sleeves 250 are threadedly connected to the first double - lead screw 240, and the two first threaded sleeves 250 are respectively located on the two threaded segments of the first double - lead screw 240. When the first double - lead screw 240 rotates, the two first threaded sleeves 250 approach or move away from each other. The first clamping plate 270 is fixedly connected to the first threaded sleeve 250 through the first fixing rod 260. The thickness of the first clamping plate 270 is the same as the depth of the hook groove 130. The second clamping plate 290 is fixedly connected to the other first threaded sleeve 250 through the second fixing rod 280.

[0044] During use, the hoisting device controls the robotic arm 210 to drive the entire hoisting component 200 to move above the front station plate 120, so that the front station plate 120 is located between the first clamping plate 270 and the second clamping plate 290, and the first clamping plate 270 and the second clamping plate 290 are at the hook groove 130 in the center of the top of the front station plate 120. Start the first driving member 230. The rotation of the output shaft of the first driving member 230 drives the first double - lead screw 240 to rotate. The two first threaded sleeves 250 approach each other, and drive the first clamping plate 270 and the second clamping plate 290 connected below through the first fixing rod 260 and the second fixing rod 280 to clamp the front station plate 120, that is, the horizontal clamping of the front station plate 120 is completed. Control the robotic arm 210 to move upward, and the front station plate 120 slides down a short distance, so that the top of the first clamping plate 270 contacts the inner wall top of the hook groove 130, and then the front station plate 120 can be hoisted to near the installation point on the bottom plate 110 by the robotic arm 210; adopting the above - mentioned scheme, the front station plate 120 can be stably clamped on both sides, improving the stability during the hoisting process.

[0045] It should be noted that a first sliding groove 221 is formed through the bottom of the first frame body 220, and a first fixing rod 260 is slidably arranged in the first sliding groove 221. The first sliding groove 221 limits the first fixing rod 260, indirectly restricting the rotation of the first threaded sleeve 250. Therefore, when the first double-headed lead screw 240 rotates, the first threaded sleeve 250 can have a relative displacement with respect to the first double-headed lead screw 240. A second sliding groove 222 is formed through the bottom of the first frame body 220, and a second fixing rod 280 is slidably arranged in the second sliding groove 222. The second sliding groove 222 limits the second fixing rod 280, indirectly restricting the rotation of the other first threaded sleeve 250. Therefore, when the first double-headed lead screw 240 rotates, this first threaded sleeve 250 can have a relative displacement with respect to the first double-headed lead screw 240.

[0046] It should be noted that the first clamping plate 270 includes a first plate body 271 and a first side roller 272. The first plate body 271 is fixed to the bottom end of the first fixing rod 260, and the first side roller 272 is rotatably arranged on one side of the first plate body 271. The first clamping plate 270 further includes an upper roller 273, and the upper roller 273 is rotatably arranged on the top of the first plate body 271. At least two upper rollers 273 are provided, and the two upper rollers 273 are symmetrically arranged on the first plate body 271. By providing the first side roller 272 and the upper roller 273, the lateral sliding friction between the inner wall of the hook groove 130 and the first plate body 271 is reduced, making the front station plate 120 move more smoothly when the positioning assembly 400 positions the front station plate 120 later. The second clamping plate 290 includes a second plate body 291 and a second side roller 292. The second plate body 291 is fixed to the bottom end of the second fixing rod 280, and the second side roller 292 is rotatably arranged on the second plate body 291. At least two groups of second side rollers 292 are provided, and the two groups of second side rollers 292 are symmetrically arranged on the second plate body 291. By providing the second side roller 292, the lateral sliding friction between the inner side of the front station plate 120 and the second plate body 291 is reduced, making the front station plate 120 move more smoothly when the positioning assembly 400 positions the front station plate 120 later. The second side roller 292 is arranged in one-to-one correspondence with the first side roller 272, improving the clamping stability of the first clamping plate 270 and the second clamping plate 290 on the front station plate 120.

[0047] In the related art, due to the large self-weight of the front station plate 120, it is only limited and fixed by the horizontal clamping structure provided at the top, and the stability is poor. If the moving speed of the robotic arm 210 is relatively fast during the hoisting process or the front station plate 120 collides with the bottom plate 110, the front station plate 120 is likely to break away from the hoisting assembly 200, which on the one hand affects the installation efficiency of the front station plate 120, and on the other hand may pose a threat to the personal safety of the installation personnel.

[0048] Please refer to Figure 5 and Figure 6, the truck front station board hoisting and fixing device provided by the present invention further includes an auxiliary fixing component 300. The auxiliary fixing component 300 includes a first sleeve 310, a first sliding rod 320, a second sleeve 330, a second sliding rod 340, a spring 350, a pressing plate 360 and a connecting rod 370. The first sleeve 310 is fixed on the first frame body 220, the first sliding rod 320 is slidably connected to the first sleeve 310, the second sleeve 330 is fixed at the bottom end of the second sliding rod 340, the top end of the second sliding rod 340 is connected to the inner wall of the second sleeve 330 through the spring 350, the pressing plate 360 is fixed at the bottom end of the second sliding rod 340, and both ends of the connecting rod 370 are rotatably connected to the first fixing rod 260 and the outer wall of the second sleeve 330 respectively.

[0049] When the device is in use, the front station board 120 is clamped by the hoisting component 200. During the process of the first clamping plate 270 and the second clamping plate 290 moving towards the front station board 120, the connecting rod 370 will also drive the second sleeve 330 to move downward, and then drive the connecting rod 370 and the pressing plate 360 fixed at the bottom end of the connecting rod to move downward through the spring 350, pressing the top of the front station board 120 from above. At this time, the spring 350 is in a compressed state, cooperating with the first clamping plate 270 to complete the longitudinal clamping of the front station board 120, further improving the stability of the hoisting process. When the robotic arm 210 moves upward, the front station board 120 slides down a small distance, the top of the first clamping plate 270 abuts against the inner top of the hook groove 130, the spring 350 slightly elongates, but is still in a pressed state, so that the pressing plate 360 maintains the downward pressing effect on the front station board 120; adopting the above scheme, while the hoisting component 200 clamps the front station board 120 horizontally, it can drive the auxiliary fixing component 300 to apply pressure to the front station board 120 from above, cooperating with the first clamping plate 270 to complete the longitudinal clamping work of the front station board 120, further improving the stability of the hoisting process, ensuring the personal safety of the installation personnel, and indirectly improving the installation efficiency of the front station board 120.

[0050] It should be noted that the pressing plate 360 includes a third plate body 361 and a lower roller 362. The third plate body 361 is fixed at the bottom end of the second sliding rod 340, the lower roller 362 is rotatably arranged on the third plate body 361, at least two groups of lower rollers 362 are arranged, and the two groups of lower rollers 362 are symmetrically arranged on the third plate body 361. By arranging the lower rollers 362, the lateral sliding friction force between the front station board 120 and the third plate body 361 is reduced, making the front station board 120 move more smoothly when the positioning component 400 positions the front station board 120 later.

[0051] For the final fixing work of the front station board 120, the primary problem faced is the positioning of the front station board 120. In the related art, it is difficult for the hoisting assembly 200 to finely adjust the position of the front station board 120 accurately. Generally, it relies on manual assistance for positioning, and it often takes a long time to make multiple adjustments to achieve accurate positioning, resulting in low efficiency. Moreover, due to the relatively large self-weight of the front station board 120, during the positioning process, even a small movement of the front station board 120 is likely to cause bumps and injuries to the installation personnel, and the personal safety of the installation personnel cannot be guaranteed.

[0052] Please refer to Figure 7 and Figure 8 As shown in FIGS. and, the truck front station board hoisting and fixing device provided by the present invention further includes a positioning assembly 400. The positioning assembly 400 includes a sliding connection member 410, a second frame body 420, a second driving member 430, a second bidirectional lead screw 440, second threaded sleeves 450, a fixing frame 460, a first positioning plate 470, and a second positioning plate 480. The sliding connection member 410 includes a third fixing rod 411, a third frame body 412, a guide rod 413, a sliding sleeve 414, and a fourth fixing rod 415. The third frame body 412 is fixedly connected to the first fixing rod 260 through the third fixing rod 411. The guide rod 413 is arranged on the third frame body 412. The sliding sleeve 414 is slidably sleeved on the guide rod 413. The top of the second frame body 420 is fixedly connected to the sliding sleeve 414 through the fourth fixing rod 415. The second driving member 430 is installed on the second frame body 420. The second driving member 430 is a motor. The end of the output shaft of the second driving member 430 penetrates through the end of the second frame body 420 and is connected to one end of the second bidirectional lead screw 440 through a coupling. Both second threaded sleeves 450 are threadedly connected to the second bidirectional lead screw 440. The two second threaded sleeves 450 are respectively located on two threaded segments of the second bidirectional lead screw 440. When the second bidirectional lead screw 440 rotates, the two second threaded sleeves 450 approach or move away from each other. The first positioning plate 470 is fixedly connected to the second threaded sleeve 450 through the fixing frame 460. When the two first positioning plates 470 approach each other, they can position the front station board 120, and can rely on both sides of the bottom plate 110 to position the front station board 120, so that the center line of the front station board 120 and the center line of the bottom plate 110 are in the same plane perpendicular to the bottom plate 110. The second positioning plate 480 is fixed on the fixing frame 460. The inner side of the second positioning plate 480 and the outer side of the first clamping plate 270 are in the same vertical plane. When the first clamping plate 270 completely enters the hook groove 130, the second positioning plate 480 also abuts against the end face of the hook groove 130. During hoisting, when the second positioning plate 480 contacts the end of the bottom plate 110, it indicates that the front station board 120 has reached the installation point at the end of the bottom plate 110. Subsequently, the movement of the front station board 120 can be further controlled by the positioning assembly 400 to align the two side edges of the front station board 120 with the two side edges of the bottom plate 110.

[0053] When the device is in use, the front station board 120 is lifted above the bottom board 110 through the hoisting assembly 200. The front station board 120 is horizontally moved until the second positioning plate 480 contacts the end of the bottom board 110. Then, the robotic arm 210 drives the front station board 120 to move downward so that its bottom contacts the upper surface of the bottom board 110. The second driving member 430 is started, and the output shaft of the second driving member 430 rotates to drive the second bidirectional lead screw 440 to rotate. The two second threaded sleeves 450 drive the two first positioning plates 470 to approach each other, applying a lateral thrust to the front station board 120 and driving the front station board 120 to translate. Due to the setting of the sliding connection member 410, when the positioning assembly 400 is stressed, the sliding sleeve 414 can drive the component fixed to the sliding sleeve 414 to have a relative displacement with the hoisting assembly 200. When one side of the first positioning plate 470 contacts the side of the front station board 120 that exceeds the edge of the bottom board 110, due to the large self-weight of the front station board 120, this first positioning plate 470 remains relatively stationary with the front station board 120 and the bottom board 110 while the positioning assembly 400 is still in working condition. Subsequently, the sliding sleeve 414 slides on the guide rod 413 towards this first positioning plate 470. The first positioning plate 470 on the other side continues to move until it contacts the edge of the bottom board 110. Since the bottom board 110 is in a fixed connection state with the external structure, this first positioning plate 470 remains relatively stationary with the bottom board 110. Subsequently, the sliding sleeve 414 slides on the guide rod 413 towards this first positioning plate 470, causing the first positioning plate 470 in contact with the front station board 120 to start applying a thrust to the side of the front station board 120 that exceeds the edge of the bottom board 110, driving the front station board 120 to move until the two side edges of the front station board 120 are aligned with the two side edges of the bottom board 110. At this time, the installer can start the installation work and establish the connection between the front station board 120 and the bottom board 110. With the above solution, the precise positioning of the front station board 120 can be automatically completed, ignoring the positional relationship between the positioning assembly 400 and the bottom board 110 and the front station board 120. The center line of the positioning assembly 400 does not need to be in the same vertical plane as the center line of either of them. During the installation process, there is no need for manual displacement or adjustment of the position of the front station board 120, greatly improving the installation efficiency and installation effect, saving human resources, and ensuring the personal safety of the installers.

[0054] It should be noted that a third sliding groove 421 is formed on the second frame body 420, and the fixing frame 460 is slidably arranged in the third sliding groove 421. The fixing frame 460 is limited by the third sliding groove 421, indirectly restricting the rotation of the second threaded sleeve 450, so that when the second bidirectional lead screw 440 rotates, the second threaded sleeve 450 can have a relative displacement with the second bidirectional lead screw 440.

[0055] Specifically, the working principle of the front station board hoisting and fixing device of the truck: During use, the hoisting instrument controls the robotic arm 210 to drive the entire hoisting assembly 200 to move above the front station board 120, so that the front station board 120 is located between the first clamping plate 270 and the second clamping plate 290, and the first clamping plate 270 and the second clamping plate 290 are at the hook groove 130 in the center of the top of the front station board 120. Start the first driving member 230, the output shaft of the first driving member 230 rotates to drive the first double-threaded lead screw 240 to rotate, and the two first threaded sleeves 250 approach each other. Through the first fixing rod 260 and the second fixing rod 280, the first clamping plate 270 and the second clamping plate 290 connected below drive to clamp the front station board 120, that is, the lateral clamping of the front station board 120 is completed. During the process of the first clamping plate 270 and the second clamping plate 290 moving towards the front station board 120, the connecting rod 370 will also drive the second sleeve 330 to move downward, and then drive the connecting rod 370 and the pressing plate 360 fixed at the bottom end of the connecting rod to move downward through the spring 350, pressing the top of the front station board 120 from above. At this time, the spring 350 is in a compressed state, cooperating with the first clamping plate 270 to complete the longitudinal clamping of the front station board 120, further improving the stability of the hoisting process. When the robotic arm 210 moves upward, the front station board 120 slides down a short distance, the top of the first clamping plate 270 abuts against the inner top of the hook groove 130, the spring 350 slightly elongates, but is still in a pressed state, so that the pressing plate 360 maintains the downward pressure on the front station board 120, cooperating with the first clamping plate 270 to complete the longitudinal clamping work of the front station board 120. Then, the front station board 120 can be hoisted to near the installation point on the bottom plate 110 by the robotic arm 210. Control the robotic arm 210 to horizontally move the front station board 120 until the second positioning plate 480 contacts the end of the bottom plate 110, and then drive the front station board 120 to move downward by the robotic arm 210 so that its bottom contacts the upper surface of the bottom plate 110. Start the second driving member 430, the output shaft of the second driving member 430 rotates to drive the second double-threaded lead screw 440 to rotate, and the two second threaded sleeves 450 drive the two first positioning plates 470 to approach each other, applying a lateral thrust to the front station board 120 and driving the front station board 120 to translate. Due to the setting of the sliding connection member 410, when the positioning assembly 400 is stressed, the sliding sleeve 414 can drive the component fixed to the sliding sleeve 414 to have a relative displacement with the hoisting assembly 200. When one side of the first positioning plate 470 contacts the side of the front station board 120 that exceeds the edge of the bottom plate 110, due to the relatively large self-weight of the front station board 120, this first positioning plate 470 remains relatively stationary with respect to the front station board 120 and the bottom plate 110, while the positioning assembly 400 is still in working condition. Subsequently, the sliding sleeve 414 slides on the guide rod 413 towards this first positioning plate 470, and the first positioning plate 470 on the other side continues to move until it contacts the edge of the bottom plate 110. Since the bottom plate 110 is in a fixed connection state with the external structure, this first positioning plate 470 remains relatively stationary with respect to the bottom plate 110.Subsequently, the sliding sleeve 414 slides on the guide rod 413 towards the first positioning plate 470, so that the first positioning plate 470 in contact with the front station plate 120 begins to exert a thrust on the side of the front station plate 120 that extends beyond the edge of the bottom plate 110, driving the front station plate 120 to move until the two side edges of the front station plate 120 are aligned with the two side edges of the bottom plate 110. At this time, the installer can start the installation work and establish the connection between the front station plate 120 and the bottom plate 110.
