[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative, and the present invention is not limited to the various structures recorded in the following embodiments. All other implementations obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.
[0023] Reference Figure 1-Figure 4 The utility model provides a manned platform with a self-locking function, including a base 1, one side of the upper surface of the base 1 is fixedly connected to a first guardrail 2 by bolts, the first guardrail 2 is fixedly connected to a fixing plate 7 by bolts, one side of the fixing plate 7 is fixedly connected to two symmetrical semicircular plates 15 by bolts, the upper surfaces of the two semicircular plates 15 are both rotatably connected to a rotating column 16, the outer circumferential wall of the rotating column 16 is fixedly connected to a locking hook 11 by bolts, the other side of the upper surface of the base 1 is fixedly connected to a second guardrail 3 by bolts, the second guardrail 3 is provided with two groups of connecting blocks 4, and the two groups of connecting blocks 4 are symmetrically distributed on the second guardrail 3 and each group has two. The two connecting blocks 4 on the same side are rotatably connected with the gate bars 5. One side of the two gate bars 5 is provided with a fixed block 8. Two slide bars 9 are slidably connected to the fixed block 8. A semi-annular rod 10 is welded to the same end of the two slide bars 9, and the semi-annular rod 10 is locked by a lock hook 11. Through the provided lock hook 11 and the semi-annular rod 10, the staff can pull the gate bar 5 after entering the equipment and lock it automatically, avoiding the staff from forgetting to lock it after closing the gate bar 5 due to negligence, thereby increasing the safety of the device, and having a simple structure and easy operation.
[0024] Among them, a torsion spring 18 is welded on the upper surface of the semicircular plate 15, and the other end of the torsion spring 18 is fixed to the surface of the lock hook 11. The torsion spring 18 can be used to apply force to the lock hook 11 to ensure that the lock hook 11 is always locked on the semi-annular rod 10 to prevent shaking during the working process, thereby causing the lock hook 11 to be separated from the semi-annular rod 10. The upper surface of the semicircular plate 15 is fixedly connected with a blocking rod 17 by bolts, and the blocking rod 17 is set at the position where the lock hook 11 rotates when locking. The blocking rod 17 can limit the starting position of the lock hook 11 to prevent the door from being closed. When the semi-circular rod 10 is locked, the semi-circular rod 10 cannot hit the lock hook 11, which results in the lock hook 11 being unable to lock the semi-circular rod 10. An inclined plate 12 is welded on one side of the lock hook 11, and the inclined plate 12 is arranged on the side close to the semi-circular rod 10. The inclined plate 12 can increase the length of the inclined surface of the lock hook 11, so that the semi-circular rod 10 is easier to get stuck in the lock hook 11. The other ends of the two slide bars 9 are fixedly connected with a connecting plate 14 by bolts. Two springs 13 are welded on one side of the connecting plate 14, and the other ends of the two springs 13 are fixed to one side of the fixing block 8. The two slide bars 9 are fixedly connected to the locking hook 11 by bolts. 9 are welded with limit plates for limiting the sliding distance of the slide bar 9, and the two limit plates are in contact with the other side of the fixed block 8. The semi-annular rod 10 can be moved by the provided spring 13 and the connecting plate 14, which can facilitate the staff to open the door fence 5. The movable distance of the slide bar 9 can be limited by the provided limit plate to prevent the slide bar 9 from shrinking too deep, thereby causing the semi-annular rod 10 to be unable to be locked with the lock hook 11. U-shaped plates 19 are welded at the four corners of the lower surface of the base 1, and multiple U-shaped plates 19 correspond to each other, and the bottom outer surface of the multiple U-shaped plates 19 The walls are fixedly connected with universal wheels 20 by bolts. Two sets of U-shaped plates 19 corresponding to each other can allow two forks of a forklift to pass through, which is convenient for limiting the equipment and preventing the equipment from shaking after lifting. Reinforcing rods 6 are provided between the inner walls on both sides of the first guardrail 2. The reinforcing rods 6 can increase the strength of the first guardrail 2, thereby increasing the strength of the equipment and increasing its safety. The surfaces of the base 1, the first guardrail 2, the second guardrail 3, and the door rail 5 are all provided with an anti-rust coating. The anti-rust coating can increase the corrosion resistance of the device, thereby increasing the service life of the device.
[0025] The utility model is divided into the following steps when used:
[0026] S1: First, after the staff enters the base 1, they pull the gate 5. When the semi-annular rod 10 contacts the inclined surface on the lock hook 11, they continue to pull the gate 5. The semi-annular rod 10 squeezes the lock hook 11 so that the lock hook 11 drives the rotating column 16 to rotate, and the torsion spring 18 is stressed. When the semi-annular rod 10 is separated from the end of the lock hook 11, the torsion spring 18 releases the torque to make the rotating column 16 rotate in the opposite direction, thereby making the lock hook 11 rotate to lock the semi-annular rod 10;
[0027] S2: When the staff needs to go out, they push the connecting plate 14 to move toward the fixed block 8, so that the two sliding bars 9 slide in the fixed block 8. When the two sliding bars 9 move, they drive the semi-annular rod 10 to move away from the fixed block 8. When the semi-annular rod 10 is out of the range of the hook of the lock hook 11, the lock hook 11 is pulled so that the lock hook 11 drives the rotating column 16 to rotate. When the lock hook 11 is away from the semi-annular rod 10, the door rail 5 can be pushed to open the door rail 5, and then the staff can go out.
[0028] Finally, a few points should be explained: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, which may refer to mechanical connection or electrical connection, or internal communication between two components, or direct connection. "upper", "lower", "left", "right", etc. are only used to indicate relative positional relationships. When the absolute position of the object being described changes, the relative positional relationship may change;
