Description

A combined mechanism for automatically transporting materials via AGV carts Technical Field

[0001] This invention belongs to the field of detection, and in particular relates to a combined mechanism for automatically transporting materials via AGV carts. Background Technology

[0002] When materials need to be transported from the surface to the underground for monitoring, the existing technology involves manually operating an electric hoist to send the materials to an underground transport vehicle. Underground personnel then push the materials, open the lead door, place the trench cover, and deliver the materials to the testing chamber. Afterward, they remove the trench cover, manually close the lead door, and begin testing. Once testing is complete, the materials are then manually removed in reverse. The entire process requires two people, is time-consuming and labor-intensive, and inefficient. Summary of the Invention

[0003] In view of this, the present invention aims to propose a combined mechanism for automatically transporting materials via AGV carts, which can eliminate the need for manual labor and achieve material transportation and detection through automated operation, making it more efficient and safer.

[0004] To achieve the above objectives, the technical solution of the present invention is implemented as follows:

[0005] A combined mechanism for automatically transporting materials via an AGV (Automated Guided Vehicle) includes a trough plate assembly, which cooperates with a lead door body. The bottom of the lead door body is set in a lead door groove via a track, and the lead door body moves on the track via a drive mechanism.

[0006] One end of the chute assembly is hinged to the doorway, while the other end can contact the lead door body. When the lead door body closes, the chute rises. When the lead door body opens, the chute falls to cover the lead door chute, allowing the AGV to pass through.

[0007] Furthermore, the through-gate assembly includes a through-gate body, a first roller, and a second roller; one end of the through-gate body is hinged to the doorway, and the other end is provided with a first roller and a second roller that cooperate with the lead door body.

[0008] Furthermore, the warehouse wall is equipped with a doorway, with tracks on the upper and lower sides of the doorway. The lead door body cooperates with the tracks to achieve sliding. A drive mechanism is also provided on the tracks to drive the lead door body on the tracks. A lead door groove is provided at the doorway, and the lower track is set in the lead door groove. When the lead door body is fully opened, the doorway is fully exposed.

[0009] Furthermore, a detection sensor is installed at the end of the track. The detection sensor is used to detect whether the lead door body is fully open. The detection sensor is connected to the controller.

[0010] Furthermore, a hinge frame is provided on the ground at the end of the lead door groove, and the through-groove plate body is hinged to the hinge frame.

[0011] Furthermore, the end of the through-slot plate body away from the hinge is formed with a bent structure, so that the through-slot plate body forms a straight plate part and a folded plate part; the ratio of the length of the folded plate part to the length of the straight plate part is in the range of 1:10-1:12.

[0012] Furthermore, using the straight plate section as a horizontal reference, the folded plate section bends upward relative to the straight plate section, and the angle formed between the folded plate section and the straight plate section ranges from 15° to 25°.

[0013] Furthermore, a first roller is provided at the end of the straight plate section near the folding plate section; a second roller is provided at the end of the folding plate section away from the straight plate section.

[0014] Furthermore, the folding plate between roller number one and roller number two has a hollowed-out opening.

[0015] Furthermore, a buffer pad is provided on the lower surface of the through-slot plate body.

[0016] Compared with existing technologies, the combined mechanism for automatically conveying materials via AGV carts described in this invention has the following advantages:

[0017] (1) The combined mechanism for automatically transporting materials by AGV trolley described in this invention is fully automated from transporting the materials underground to transporting them into the testing room. No human intervention is required, which reduces labor costs and greatly improves efficiency.

[0018] (2) The combined mechanism of the present invention, which automatically transports materials by AGV trolley, does not require personnel to enter the underground, which greatly avoids safety accidents caused by personnel turning on the radiation source in the detection room due to misoperation.

[0019] (3) The combined mechanism for automatically conveying materials by AGV trolley described in this invention has no power on the trough plate assembly itself. It uses the thrust generated by the action of the lead gate to lift and lower the plate. This reduces costs; it also reduces the control of the logic program by moving synchronously with the lead gate, thus avoiding impact damage caused by program errors; and it has a simple structure, reducing maintenance frequency.

[0033] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0034] A combined mechanism for automatically transporting materials via an AGV trolley 1, as shown in Figures 1-7, includes a trough plate assembly 4, which cooperates with a lead door body 3. The bottom of the lead door body 3 is set in a lead door groove via a track, and the lead door body 3 moves on the track via a drive mechanism.

[0035] One end of the through-slot plate assembly 4 is hinged to the doorway, and the other end can make contact with the lead door body 3; when the lead door body 3 is closed, the through-slot plate is raised; when the lead door body 3 is opened, the through-slot plate is lowered to cover the lead door slot; thus allowing the AGV trolley 1 to pass through.

[0036] Preferably, the through-slot plate assembly 4 includes a through-slot plate body 8, a first roller 11, and a second roller 10; one end of the through-slot plate body 8 is hinged to the doorway, and the other end is provided with a first roller 11 and a second roller 10 that cooperate with the lead door body 3, and the first roller 11 and the second roller 10 can contact the side of the lead door body 3.

[0037] The chute assembly 4 is a non-powered mechanism. The front end of the chute body 8 is angled upwards, with roller 11 and roller 10 installed on the angled part. When the lead door is closed, the front end of the lead door first contacts roller 10, which then exerts a pushing force on it. Because the front end of the chute body 8 is an angled structure, a component force perpendicular to the angled surface is generated. Through the constraint of the rotating shaft, the chute is rotated and lifted. When the angled surface is perpendicular to the ground, roller 11 contacts the end face of the lead door and continues to push the chute to rotate until the lead door body reaches the end position. When the lead door body is opened, the chute assembly 4 is no longer subjected to a pushing force. It is subjected to its own gravity and the constraint of the rotating shaft, and falls around the rotating shaft until it covers the lead door groove, allowing the trolley to pass through.

[0038] Preferably, the wall of the testing chamber is provided with a doorway, and tracks are provided on the upper and lower sides of the doorway. The lead door body 3 cooperates with the tracks to achieve sliding. A drive mechanism is also provided on the tracks to drive the lead door body 3 on the tracks. A lead door groove is provided at the doorway, and the lower track is set in the lead door groove. When the lead door body 3 is fully opened, the doorway is fully exposed. This lead door setting is a conventional solution, and the opening and closing of the lead door body 3 through the drive mechanism and guide rail is also an existing technical solution.

[0039] Preferably, a detection sensor 6 is provided at the end of the track. The detection sensor 6 is used to detect whether the lead door body 3 is fully open. The detection sensor 6 is connected to the controller. When the lead door body 3 is fully open and touches the detection sensor 6, the controller sends the next instruction to protect the cooperation between the lead door body 3 and the AGV trolley 1.

[0040] Preferably, a hinge frame 9 is provided on the ground at the end of the lead door groove, and the through-groove plate body 8 is hinged to the hinge frame 9 to realize the installation of the through-groove plate body 8.

[0041] Preferably, the end of the through-slot plate body 8 away from the hinge has a bent structure, so that the through-slot plate body 8 has a straight plate part and a bent plate part; the ratio of the length of the bent plate part to the length of the straight plate part is in the range of 1:10.

[0042] Preferably, the straight plate portion is used as a horizontal reference, and the folded plate portion is bent upward relative to the straight plate portion, with the angle between the folded plate portion and the straight plate portion ranging from 25°.

[0043] The dimensions of the slide plate body 8 are designed so that when the slide plate body 8 is raised or lowered, the first roller 11 and the second roller 10 can contact the lead door body 3 to protect the lead door body 3 and prevent the sharp edges of the slide plate body 8 from directly contacting the lead door body 3 and causing damage.

[0044] Preferably, a first roller 11 is provided at the end of the straight plate section near the folding plate section; a second roller 10 is provided at the end of the folding plate section away from the straight plate section.

[0045] Preferably, the folding plate between the first roller 11 and the second roller 10 is provided with a hollow opening, which can provide clearance for the rotation of the first roller 11 and the second roller 10, making the rotation smoother.

[0046] Preferably, the lower surface of the through-slot plate body 8 is provided with a buffer pad, which can buffer the contact between the through-slot plate body 8 and the lead door body 3; it can also buffer the contact between the through-slot plate body 8 and the lead door slot or the ground.

[0047] Working principle: The manual places materials onto the AGV trolley 1. The "Run" button is pressed on the controller, opening the roller shutter door of the elevator 2 on the ground floor. The AGV, with its magnetic stripe, enters the elevator 2, which descends to the basement level. The elevator 2 connects with the AGV control system. Once in position, the elevator 2 sends a signal to the controller, and the AGV trolley 1 starts moving, exiting the elevator 2 with its magnetic stripe. After passing through the first through-beam sensor 7 and then the second through-beam sensor 5, the controller determines the position of the AGV trolley 1 and issues a command. At this point, the AGV trolley 1 stops, and simultaneously, the lead door 3... Upon receiving the sensor signal, the lead gate body 3 opens. Simultaneously, the channel plate body 8, relying on the lead gate body 3, moves downwards due to gravity as the lead gate body 3 opens, rotating around its axis and covering the lead gate channel. The lead gate then opens to its full position, touching the detection sensor 6. The detection sensor 6 sends a signal to the AGV trolley 1, which starts and enters the detection chamber along the magnetic strip. After transporting the materials, the AGV trolley 1 returns, exits the lead gate, and passes through the second through-beam sensor 5 and the first through-beam sensor 7 in sequence. Upon receiving the signal, the lead gate body 3 closes, and the detection begins.

[0048] After the inspection is completed, the lead door opens, the collision detection sensor 6 receives the signal, the AGV trolley 1 starts, enters the inspection chamber, transports the material out, passes through the lead door body 3, and then passes through the second through-beam sensor 5 and the first through-beam sensor 7 in sequence. The lead door body 3 receives the signal, the lead door closes, and the trough plate body 8 is pushed by the force and rotates around the rotating shaft to rise. The first roller 11 and the second roller 10 make contact with the side of the lead door body 3. The AGV trolley 1 continues forward along the magnetic strip into the elevator 2. The underground floor roller shutter door closes, the elevator 2 car rises to the ground floor, the AGV trolley 1 exits the elevator 2, the ground floor elevator 2 roller shutter door closes, the AGV trolley 1 exits the elevator 2 and reaches the material position along the magnetic strip to wait for manual material retrieval; then the next work cycle begins.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
