DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] like Figures 1 to 4As shown, the first conveying line body 1 and the second conveying line body 2 have the same conveying direction and are located in the same straight line. The conveying heights of the first conveying line body 1 and the second conveying line body 2 are the same. The first conveying line body 1 and the second conveying line body 2 are spaced apart in the length direction, and the positions are fixed relative to the ground by the support legs 4 and cannot be moved. The door-opening conveying line body 3 is an independent conveying line body. The conveying height of the door-opening conveying line body 3 is the same as the height of the first conveying line body 1 and the second conveying line body 2, and the length matches the interval length between the first conveying line body 1 and the second conveying line body 2. The conveying direction of the first conveying line body 1, the door-opening conveying line body 3 and the second conveying line body 2 is to convey from the second conveying line body 2. As to the first conveyor line body 1, a universal wheel 5 is provided under the support leg 4 of the door-opening conveyor line body 3, which can move horizontally relative to the ground. One end of the first conveyor line body 1 is hinged to one end of the door-opening conveyor line body 3, specifically through the respective relative support legs 4 connected by a hinge 6. The hinge 6 can be set on the left or right side of the conveying direction. When set on the left side of the conveying direction, the door-opening conveyor line body 3 can rotate horizontally to the left around the hinge 6. When set on the right side of the conveying direction, the door-opening conveyor line body 3 can rotate horizontally to the right around the hinge 6. The specific setting position of the hinge 6 can be determined according to the actual working conditions, which does not affect the implementation of the present application. The present application is explained by taking the setting on the left side of the conveying direction as an example. The stopping mechanism acts on the second conveyor line body 2, and can stop or release the load on the second conveyor line body 2. When the door-opening conveyor line body 3 is in the first position, the conveying direction of the door-opening conveyor line body 3 is consistent with the conveying direction of the first conveyor line body 1 and the second conveyor line body 2 and is located in the same straight line. The door-opening conveyor line body 3 is placed between the first conveyor line body 1 and the second conveyor line body 2. The stopping mechanism is in the releasing state, and the load can be conveyed from the second conveyor line body 2 to the door-opening conveyor line body 3 and then to the first conveyor line body 1, that is, the first conveyor line body 1, the door-opening conveyor line body 3 and the second conveyor line body 2 are connected in sequence, and the conveying system is in a closed conveying state; when the door-opening conveyor line body 3 is in the second position, the door-opening conveyor line body 3 is around the hinge 6 position The door opening conveyor line body 3 is arranged to rotate horizontally, and the end of the door opening conveyor line body 3 close to the second conveyor line body 2 gradually moves away from the second conveyor line body 2. After rotating horizontally at a certain angle, the door opening conveyor line body 3 releases the docking state with the first conveyor line body 1 and the second conveyor line body 2, and the blocking mechanism switches to the blocking state. The load cannot continue to move from the second conveyor line body 2 to the first conveyor line body 1, and stays on the second conveyor line body 2, completing the door opening state of the conveying system. This embodiment can ensure that the entire conveying system can perform the door opening action at the designated position, which is convenient for people to pass through. At the same time, it ensures that in the door opening state, the load will not move out of the conveying system due to the second conveyor line body 2 not stopping, thereby improving the safety of the conveying system and the working environment.

[0023] In some embodiments, Figure 1 , Figures 4 to 6As shown, the stop mechanism includes a stop frame 7 and a limit plate 8. The stop frame 7 is a strip-shaped bent metal part, including an upper end 701, a hinged part 702 and a lower end 703 connected in sequence, wherein the mass of the upper end 701 is less than the mass of the lower end 703, and the hinged part 702 is a round hole. The stop frame 7 can be set at the end of the second conveying line body 2 relative to the first conveying line body 1 by screws, and the stop frame 7 can rotate freely in a vertical plane around the hinged part 702. Since the mass of the upper end 701 is less than the mass of the lower end 703, under the action of its own weight, the upper end 701 will be vertically upward relative to the lower end 703, and the position of the upper end 701 will be located in the conveying plane of the second conveying line body 2 and the height will be higher than the height of the conveying plane of the second conveying line body 2. The limit plate 8 is set at the end of the door-opening conveying line body 3 close to the second conveying line body 2, opposite to the position of the stop frame 7. When the door-opening conveying line body 3 is in the first position, as shown in FIG. Figure 5 , the limit plate 8 contacts the lower end 703 of the stop frame 7 and pushes the stop frame 7 to rotate around the hinge 702 until the upper end 701 of the stop frame 7 is not located in the conveying plane of the second conveying line body 2. At this time, the load can be conveyed from the second conveying line body 2 to the door-opening conveying line body 3, and the second conveying line body 2 is in a released state. When the door-opening conveying line body 3 moves from the first position to the second position, as shown in FIG. Figure 6 , the limit plate 8 is away from the lower end 703 of the blocking frame 7. Under the action of its own weight, the upper end 701 of the blocking frame 7 will be located on the conveying plane of the second conveying line body 2 and higher than the conveying plane of the second conveying line body 2. The load passing through the second conveying line body 2 will be blocked on the second conveying line body 2 by the upper end 701, and the second conveying line body 2 is in a blocking state. This embodiment uses a mechanical structure to switch between blocking and releasing, so that the blocking and releasing states of the second conveying line body 2 are opposite to the position of the door-opening conveying line body 3, effectively preventing the load from moving out of the second conveying line body 2 in the door-opening state, and no additional control system and components are required, effectively reducing costs.

[0024] In some embodiments, Figure 1 and Figure 4As shown, the first positioning block 9 is provided at the leg 4 of the door-opening conveying line body 3 close to the second conveying line body 2, and the second positioning block 10 is provided at the leg 4 of the door-opening conveying line body 3 close to the second conveying line body 2. The first positioning block 9 and the second positioning block 10 are both provided with through holes in the vertical direction. When the door-opening conveying line body 3 is in the first position, that is, the door-opening conveying line body 3 is butt-connected with the second conveying line body 2, the first positioning block 9 and the second positioning block 10 will be engaged, and their respective through holes will be located on the same vertical line, and the limit rod 11 can be sequentially penetrated into the first positioning block from the vertical direction. 9 and the through holes of the second positioning block 10, thereby relatively fixing the positions of the first positioning block 9 and the second positioning block 10, and further relatively fixing the positions of the door-opening conveying line body 3 and the second conveying line body 2, improving the stability of the docking of the door-opening conveying line body 3 and the second conveying line body 2, preventing the door-opening conveying line body 3 from accidentally moving, and ensuring the continuity of the conveying system. When the conveying system needs to be in the door-opening state, the limit rod 11 is moved out of the position of the first positioning block 9 and the second positioning block 10. After the limit state is released, the door-opening conveying line body 3 can be moved to the second position.

[0025] In some embodiments, Figures 1 to 4 As shown, the stopping mechanism includes a stopping and releasing device 12 and a detecting member 13. The stopping and releasing device 12 is arranged on the second conveying line body 2 and is located at one end close to the first conveying line body 1. It can switch between the stopping and releasing states and is used to stop and release the load on the second conveying line body 2. The detecting member 13 is arranged at the support leg 4 of the second conveying line body 2. The detecting member 13 can be a photoelectric sensor to detect whether there is an object at the corresponding position. It is specifically located above the second positioning block 10. When the door opening conveying line body 3 is in the first position, the first positioning block 9 and the second positioning block 10 are engaged, and the limit rod 11 passes through the first positioning block 9 and the second positioning block 10. At this time, the detecting member 13 will detect the position of the limit rod 11 and generate a first detection signal. The first detection signal will control the stopping and releasing device 12 to be in the releasing state. When the limit rod 11 moves out of the first positioning block 9 and the second positioning block 10, the detecting member 13 will not detect the limit rod 11 and generate a second detection signal. The second detection signal will control the stopping and releasing device 12 to be in the stopping state. By detecting the position of the limit rod 11 through the detection part 13, the position of the door opening conveyor line body 3 and the moving trend of the door opening conveyor line body 3 can be accurately obtained. That is, if you want to move the door opening conveyor line body 3 from the first position to the second position, you must first move the limit rod 11 out. At this time, you can control the second conveyor line body 2 to be in a blocking state according to the detection signal. When the door opening conveyor line body 3 moves from the second position to the first position and the limit rod 11 is inserted into the first positioning block 9 and the second positioning block 10, after ensuring that the docking state is stable, the second conveyor line body 2 is controlled to be in a blocking state according to the detection signal, which further improves the safety and reliability of the conveying system.

[0026] In some embodiments, Figures 1 to 3As shown, the door opening conveyor line body 3 is composed of single-sided conveyor lines 301 opposite to each other on both sides, and the single-sided conveyor lines 301 on both sides are aligned close to one end of the first conveyor line body 1, and the length of the single-sided conveyor line 301 close to the hinge 6 is greater than the length of the single-sided conveyor line 301 away from the hinge 6, thereby ensuring that during the horizontal rotation of the door opening conveyor line body 3, the end of the single-sided conveyor line 301 away from the hinge 6 close to the second conveyor line body 2 will not interfere with the second conveyor line body 2.

[0027] In some embodiments, Figures 1 to 3 As shown, a transition roller 15 is provided at one end of the single-side conveyor line 301 of the second conveyor line body 2 close to the side away from the hinge 6 through a roller bracket 14. The transition roller 15 can rotate freely horizontally to make up the distance between the second conveyor line body 2 and the single-side conveyor line 301 of the door-opening conveyor line body 3 corresponding to the transition roller 15, thereby ensuring stable transportation of the load between the second conveyor line body 2 and the door-opening conveyor line body 3.

[0028] In some embodiments, Figures 1 to 3 As shown, an anti-collision mechanism is provided, and the anti-rotation mechanism includes an anti-collision bracket 16 and an anti-collision block 17. The anti-collision bracket 16 is protrudingly arranged on the first conveying line body 1 close to the hinge 6 side, and a plurality of anti-collision blocks 17 are arranged on the anti-collision bracket 16. The anti-collision block 17 has a certain elasticity. When the door-opening conveying line body 3 is in the second position, or in the over-position state of the second position, the door-opening conveying line body 3 will abut against the anti-collision block 17 for buffering, thereby preventing the door-opening conveying line body 3 from colliding with the first conveying line body 1 when the conveying system is in the door-opening state, causing damage, thereby improving safety.
