Description

Technical Field

[0001] This application relates to the field of shuttle bus technology, specifically a shuttle bus. Background Technology

[0002] Steel is indispensable in industrial production. To facilitate the transportation of steel, shuttle vehicles are needed. Shuttle vehicles move at a relatively stable speed and can move along specific routes, thereby improving the efficiency of industrial processes.

[0003] An existing patent (publication number: CN217497557U) discloses a shuttle bus, including a platform, a baffle above the platform, a frame fixedly connected below the platform, wheels mounted below the frame, a shovel plate on the outer side of the wheels, an infrared sensor below the platform, an alarm mounted on the outer side of the platform, a first fixing sleeve fixedly connected to the outer side of the frame below, a clamping rod inside the first fixing sleeve, a clamping plate fixedly connected to the outer end of the clamping rod, a drive rod inside the second fixing sleeve, an electric telescopic rod fixedly connected to the right end of the drive rod, a connecting rod outside the drive rod, the outer end of the connecting rod connecting to the clamping rod, and a guide rail below the wheels. The infrared sensor detects pedestrians, preventing collisions and facilitating braking, thus improving safety.

[0004] The aforementioned shuttle bus cannot accurately locate its parking position through its braking mechanism when it stops, resulting in a discrepancy between the parking position and the intended parking position. This leads to inaccurate track alignment and affects the transfer of materials on the shuttle bus. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a shuttle vehicle that has the advantages of accurately locating the parking position, ensuring that the parking position matches the predetermined parking position, and accurately performing track docking and material transfer operations. This solves the problem that when the shuttle vehicle stops, the braking mechanism cannot accurately locate the parking position, resulting in a discrepancy between the parking position and the predetermined parking position, which leads to inaccurate track docking and affects the transfer of materials on the shuttle vehicle.

[0006] To achieve the aforementioned goals of accurately locating parking positions, ensuring that the parking position matches the predetermined parking location, and accurately performing track docking and material transfer operations on the shuttle vehicle, this application provides the following technical solution: A shuttle vehicle includes a placement plate, with four support legs at the four corners of the bottom of the placement plate. Four wheels are rotatably mounted on the bottom of the four support legs via a rotating frame. The four wheels are engaged in pairs on two tracks, with a positioning rod between the two tracks. A fixing plate is hinged to the bottom of the placement plate via a hinge frame. A first positioning plate is provided at one end of the fixing plate, and a second positioning plate is provided at the other end of the fixing plate. The distance between the first positioning plate and the second positioning plate is equal to the width between the left and right sides of the positioning rod. A push rod is hinged to one side of the first positioning plate via a hinge frame. The inner wall of one end of the push rod is hinged to one end of the telescopic inner rod via the hinge frame. The outer surface of the other end of the telescopic inner rod is inserted into the inner wall of the middle part of the telescopic outer tube. One end of the telescopic outer tube is set at the bottom of the placement plate via a support plate. A reset plate is set at the bottom of one end of the telescopic inner rod. A push plate is set on one side of the reset plate. The inner wall of one end of the push plate is threaded to the outer surface of the middle part of the threaded rod. One end of the threaded rod is set at one end of the motor. The top of the motor is set at the bottom of the placement plate via a fixing block.

[0007] The above scheme involves the second positioning plate contacting the positioning rod, which in turn pushes the second positioning plate to swing relative to the first positioning plate. This allows the positioning rod to enter between the first and second positioning plates. The push plate then pushes the reset plate to reset, causing the first and second positioning plates to swing back to their original positions, aligning with the angle of insertion with the positioning rod. Simultaneously, the position of the shuttle car can be finely adjusted via the positioning rod, achieving precise positioning of the parking position. This ensures that the parking position matches the predetermined parking position, enabling accurate track docking and the transfer of materials on the shuttle car.

[0008] Furthermore, the positioning rod is located on the moving trajectory of the first positioning plate and the second positioning plate, and a hydraulic rod is provided at the bottom of the positioning rod.

[0009] With the above solution, when the shuttle bus needs to be stopped at a fixed position, the hydraulic rod can be used to push the positioning rod upward, so that the positioning rod reaches a suitable height and pushes the first positioning plate and the second positioning plate to swing. The positioning rod can then be inserted between the first positioning plate and the second positioning plate to position the shuttle bus.

[0010] Furthermore, the top outer surface of the positioning rod is inclined, and the inclined top outer surface of the positioning rod is slidably connected to one side of the bottom of the second positioning plate.

[0011] The above scheme allows the positioning rod to be smoothly inserted between the second and first positioning plates after the second positioning plate swings by setting the inclined outer surface of the top of the positioning rod. At the same time, when the positioning rod moves upward by the hydraulic rod, the bottom of the second positioning plate will slide on the inclined outer surface of the top of the positioning rod to adjust the position of the shuttle car, so that the positioning rod can be accurately inserted between the first and second positioning plates to accurately position the shuttle car.

[0012] Furthermore, the bottom of the second positioning plate is located above the bottom of the first positioning plate.

[0013] The above scheme allows the second positioning plate to move smoothly to the side of the positioning rod away from the first positioning plate after swinging, so that the openings of the first and second positioning plates can be smoothly fitted onto the positioning rod.

[0014] Furthermore, a positioning frame is provided on the top of the second positioning plate, one end of which abuts against one side of the baffle, and the baffle is located at the bottom of the placement plate.

[0015] The above solution fixes the swing angle of the second positioning plate and the first positioning plate during reset by the contact between the positioning frame and the baffle, so that the first positioning plate and the second positioning plate can remain perpendicular after reset.

[0016] Furthermore, a spring is provided at one end of the inner wall of the telescopic outer tube, and one end of the spring is located at one end of the telescopic inner rod.

[0017] The above scheme allows the spring to generate thrust on the telescopic inner rod, which in turn creates resistance to the swing of the first positioning plate by the push rod. This, in turn, allows the first positioning plate to work with the positioning rod to further decelerate the shuttle bus.

[0018] Furthermore, the inner wall of the push plate away from the threaded rod is slidably disposed on the outer surface of the middle part of the limiting rod, and the limiting rod is disposed at the bottom of the placement plate through the support plate.

[0019] The above solution allows for the fixation of the angle of the push plate during movement by sliding the inner wall of one end of the push plate on the outer surface of the middle part of the limiting rod, thereby improving the stability of the push plate during movement.

[0020] Furthermore, a baffle strip is provided on the top edge of the placement plate, and the insertion hole on the top of the baffle strip is inserted into the insertion rod at the bottom of the guardrail.

[0021] The above solution uses guardrails and edge strips to protect items placed on top of the placement board, preventing them from slipping off. The guardrails can also be removed from the top of the edge strips using the combination of inserts and holes, making it easy to load items onto the top of the placement board.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This type of shuttle vehicle uses a second positioning plate to contact a positioning rod, which in turn pushes the second positioning plate to swing relative to the first positioning plate. This allows the positioning rod to enter between the first and second positioning plates. A push plate then pushes a reset plate to reset, causing the first and second positioning plates to swing back to their original positions, aligning with the angle of insertion with the positioning rod. Simultaneously, the position of the shuttle vehicle can be finely adjusted via the positioning rod, achieving precise positioning of the parking position and ensuring that the parking position matches the predetermined parking position. This enables precise track docking and the transfer of materials on the shuttle vehicle. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 , Figure 2 and Figure 3In this embodiment, a shuttle vehicle includes a placement plate 1. Four support legs 2 are located at the four corners of the bottom of the placement plate 1. Four wheels 3 are rotatably mounted on the bottom of the four support legs 2 via a rotating frame. The four wheels 3 are engaged in pairs on two tracks 4. A positioning rod 6 is provided between the two tracks 4. A fixing plate 7 is hinged to the bottom of the placement plate 1 via a hinge frame. A first positioning plate 8 is provided at one end of the fixing plate 7, and a second positioning plate 9 is provided at the other end of the fixing plate 7. The distance between the first positioning plate 8 and the second positioning plate 9 is equal to the width between the left and right sides of the positioning rod 6. The first positioning plate 8 is positioned on one side... A push rod 10 is hinged to a hinge frame. One end of the push rod 10 is hinged to one end of a telescopic inner rod 11. The outer surface of the other end of the telescopic inner rod 11 is inserted into the inner wall of the middle part of the telescopic outer tube 12. One end of the telescopic outer tube 12 is set at the bottom of the placement plate 1 through a support plate. A reset plate 17 is set at the bottom of one end of the telescopic inner rod 11. A push plate 16 is set on one side of the reset plate 17. One end of the push plate 16 is threaded to the outer surface of the middle part of the threaded rod 15. One end of the threaded rod 15 is set at one end of the motor 14. The top of the motor 14 is set at the bottom of the placement plate 1 through a fixing block.

[0032] Please see Figure 1 , Figure 2 and Figure 3 The positioning rod 6 is located on the moving trajectory of the first positioning plate 8 and the second positioning plate 9. The bottom of the positioning rod 6 is equipped with a hydraulic rod 5. When it is necessary to stop the shuttle bus in a fixed position, the positioning rod 6 can be pushed upward by the hydraulic rod 5, so that the positioning rod 6 reaches a suitable height and pushes the first positioning plate 8 and the second positioning plate 9 to swing. The positioning rod 6 can also be inserted between the first positioning plate 8 and the second positioning plate 9 to position the shuttle bus.

[0033] Please see Figure 1 and Figure 2 The top outer surface of the positioning rod 6 is inclined, and the inclined outer surface of the top of the positioning rod 6 is slidably connected to one side of the bottom of the second positioning plate 9. The inclined outer surface of the top of the positioning rod 6 allows the positioning rod 6 to be smoothly inserted between the second positioning plate 9 and the first positioning plate 8 after the second positioning plate 9 swings. At the same time, when the positioning rod 6 moves upward through the hydraulic rod 5, the bottom of the second positioning plate 9 will slide on the inclined outer surface of the top of the positioning rod 6 to adjust the position of the shuttle car, so that the positioning rod 6 can be accurately inserted between the first positioning plate 8 and the second positioning plate 9 to accurately position the shuttle car.

[0034] Please see Figure 2 and Figure 4 The bottom of the second positioning plate 9 is located above the bottom of the first positioning plate 8, so that the second positioning plate 9 can move smoothly to the side of the positioning rod 6 away from the first positioning plate 8 after swinging, so that the openings of the first positioning plate 8 and the second positioning plate 9 can be smoothly fitted onto the positioning rod 6.

[0035] Please see Figure 2 The second positioning plate 9 is provided with a positioning frame 20 on its top. One end of the positioning frame 20 abuts against one side of the baffle 19. The baffle 19 is located at the bottom of the placement plate 1. The abutment between the positioning frame 20 and the baffle 19 can fix the swing angle of the second positioning plate 9 and the first positioning plate 8 when resetting, so that the first positioning plate 8 and the second positioning plate 9 can remain perpendicular after resetting.

[0036] Please see Figure 4 A spring 13 is provided at one end of the inner wall of the telescopic outer tube 12. One end of the spring 13 is located at one end of the telescopic inner rod 11. The thrust generated by the spring 13 on the telescopic inner rod 11 can work with the push rod 10 to generate a resistance to the swing of the first positioning plate 8, thereby enabling the first positioning plate 8 to work with the positioning rod 6 to further decelerate the shuttle car.

[0037] Please see Figure 3 The inner wall of the push plate 16 away from the threaded rod 15 is slidably disposed on the outer surface of the middle part of the limiting rod 18. The limiting rod 18 is disposed at the bottom of the placement plate 1 through the support plate. The angle of the push plate 16 when it moves can be fixed by the inner wall of the push plate 16 sliding on the outer surface of the middle part of the limiting rod 18, thereby improving the stability of the push plate 16 when it moves.

[0038] Please see Figure 1 and Figure 2 The top edge of the placement board 1 is provided with a baffle strip 21. The insertion hole at the top of the baffle strip 21 is connected to the insertion rod at the bottom of the guardrail 22. The guardrail 22, together with the baffle strip 21, can protect the items placed on the top of the placement board 1 and prevent them from slipping off the top of the placement board 1. At the same time, the guardrail 22 can be removed from the top of the baffle strip 21 by the cooperation of the insertion rod and the insertion hole, making it convenient to load items onto the top of the placement board 1.

[0039] In this embodiment, a shuttle vehicle uses a second positioning plate 9 to contact a positioning rod 6, thereby causing the second positioning plate 9 and the first positioning plate 8 to swing. This allows the positioning rod 6 to enter between the first positioning plate 8 and the second positioning plate 9. The push plate 16 pushes the reset plate 17 to reset, causing the first positioning plate 8 and the second positioning plate 9 to swing and reset to the angle that matches the insertion angle with the positioning rod 6. At the same time, the position of the shuttle vehicle can be finely adjusted by the positioning rod 6, achieving precise positioning of the parking position and ensuring that the parking position matches the predetermined parking position. This enables precise docking with the track 4 and the transfer of materials on the shuttle vehicle.

[0040] It should be noted that multiple sets of hydraulic rods 5 and positioning rods 6 can be set in the track 4 according to the location where the shuttle bus needs to stop. When the shuttle bus needs to stop at a certain point on the track 4, the hydraulic rod 5 at the corresponding position will drive the positioning rod 6 to move upward, thereby positioning the shuttle bus at that position.

[0041] The working principle of the above embodiment is as follows: the guardrail 22 is pulled upward from the edge strip 21 and removed. The items to be transferred are placed on the top of the placement plate 1. Then the guardrail 22 is reinstalled on the edge strip 21. The shuttle car moves on the track 4 to transfer the items. When the shuttle car needs to be stopped at a certain point, the hydraulic rod 5 at the corresponding position will push the positioning rod 6 upward, so that the positioning rod 6 can block the second positioning plate 9 and the first positioning plate 8. When the shuttle car brakes and decelerates, the second positioning plate 9 will be blocked by the positioning rod 6 and swing, causing the first positioning plate 8 to swing. When the second positioning plate 9 swings to a certain angle by the movement of the shuttle car, the second positioning plate 9 will pass over one side of the positioning rod 6, so that the openings of the first positioning plate 8 and the second positioning plate 9 are fitted onto the positioning rod 6. When the first positioning plate 8 swings, it will drive the push rod 10 to swing, so that the push rod 10 drives the telescopic inner rod 11 to insert into the telescopic outer tube 12. Inside, the spring 13 is compressed, and the thrust of the spring 13 will generate resistance to the swing of the first positioning plate 8, thereby decelerating the shuttle car again. After the shuttle car stops completely, the motor 14 works, driving the threaded rod 15 to rotate, causing the push plate 16 to move towards the reset plate 17, pushing the reset plate 17 to pull the telescopic inner rod 11 out of the telescopic outer tube 12, thereby causing the push rod 10 to drive the first positioning plate 8 to swing and reset. When the first positioning plate 8 swings, it will make a slight adjustment to the position of the shuttle car through the positioning rod 6, causing the shuttle car to move backward a little until the first positioning plate 8 and the second positioning plate 9 swing to a vertical state. The motor 14 stops working, the hydraulic rod 5 works again, driving the positioning rod 6 to move upward, so that the positioning rod 6 gradually inserts between the first positioning plate 8 and the second positioning plate 9, until the left and right sides of the positioning rod 6 are completely attached to the inner wall of the side adjacent to the first positioning plate 8 and the second positioning plate 9, completing the positioning of the shuttle car.
