Figures 1-6 It includes base 1, silica gel plate 2, connecting sleeve 3, rotating shaft 4 and vertical rod 6. The above-mentioned base 1 and connecting sleeve 3 are fixedly installed on the wall.

[0030] The base 1 is in contact with the ground, the base 1 is hinged to the silica gel plate 2 near the side of the elevator door, the connecting sleeve 3 is arranged above the base 1, the base 1 and the connecting sleeve 3 are on the same central axis, the rotating shaft 4 is pivoted in the connecting sleeve 3, the end of the rotating shaft 4 extends to the outside of the connecting sleeve 3, the end of the rotating shaft 4 is welded with the railing 5, the end of the railing 5 away from the rotating shaft 4 is bent, and the railing 5 is fixedly inserted with the vertical rod 6.

[0031] The rail 5 is welded with a hoop 51, and the vertical rod 6 vertically penetrates the hoop 51.

[0032] The base 1 is provided with a sliding groove 11 at the top, the sliding groove 11 is semicircular, the center of the sliding groove 11 is aligned with the central axis of the base 1, the lower end of the vertical rod 6 is in sliding fit with the sliding groove 11, the base 1 is provided with a trigger mechanism near the elevator side, the trigger mechanism drives the vertical rod 6 to make circular motion around the central axis.

[0033] It also comprises a grating module 9 and a control module 16, the control module 16 is arranged and installed at the top of the base 1, the grating module 9 is arranged and installed outside the base 1, and the grating module 9 is located in front of the silica gel plate 2. The grating modules 9 on both sides of the elevator are aligned. The emitted light irradiates on the other side.

[0034] The control module 16 is used for controlling the work of each electronic part, and the entire device circuit is in communication with the indoor circuit. Since it is a conventional technical means, it is not described in detail.

[0035] Working principle: when the trailer carrying goods enters the elevator, the trailer contacts the silica gel plate 2, the trailer pushes the silica gel plate 2 to overturn, so that the silica gel plate 2 deflects towards the inside of the elevator door, the silica gel plate 2 contacts the trigger mechanism to make the vertical rod 6 move, the vertical rod 6 drives the rail 5 to rotate, and the curved end of the rail 5 blocks the elevator door.

[0036] Because there is space between the bottom of the trailer and the ground, the grating 9 is not completely blocked.

[0037] The trigger mechanism is composed of a contact lever 7 and a gear 8. The base 1 is provided with a cavity 13, the sliding groove 11 is in communication with the cavity 13, the cavity 13 is provided with a straight groove 14 near one side of the silica gel plate 2, the contact lever 7 is in sliding fit in the straight groove 14, and the outer end of the contact lever 7 extends to the outside of the base 1. The inner end of the contact lever 7 is welded with a rack 73, and the gear 8 is pivoted in the cavity 13. The gear 8 is on the same central axis as the connecting sleeve 3, the rack 73 is engaged with the gear 8. The rod body of the vertical rod 6 is welded with an extension rod 61, one end of the extension rod 61 away from the vertical rod 6 extends into the cavity 13 and is clamped with the gear 8.

[0038] The inner end of the contact lever 7 is welded with a gasket 71, the gasket 71 is welded with the rack 73 away from the contact lever 7, a metal ring 141 is welded in the straight groove 14, and the gasket 71 can contact the metal ring 141. The rack 73 penetrates the metal ring 141 and extends into the cavity 13, and the gasket 71 is welded with a thick spring 72 away from the metal ring 141, and the thick spring 72 is welded with the inner wall of the straight groove 14 away from the gasket 71.

[0039] The extension rod 61 is provided with teeth at one end away from the vertical rod 6, and the teeth of the extension rod 61 are engaged with the gear 8.

[0040] Working principle: when the silica gel plate 2 deflects towards the inside of the elevator door, the silica gel plate 2 touches the outer end of the abutting rod 7, the abutting rod 7 carries the rack 73 to move towards the inside of the cavity 13, the thick spring 72 is lengthened, the rack 73 drives the gear 8 to rotate, the gear 8 drives the vertical rod 6 to move along the sliding groove 11 through the extension rod 61, the vertical rod 6 drives the rail 5 to deflect, and the curved end of the rail 5 abuts against the elevator door. Thus, the elevator door is prevented from closing when the trailer is not completely inside the elevator.

[0041] When the trailer is completely inside the elevator door, the thick spring 72 is contracted to push the abutting rod 7 to move outward, the gear 8 reversely rotates to reset the vertical rod 6 and the rail 5.

[0042] Secondly, it can be seen from the attached Figure 1 The length of the silica gel plate 2 is less than the length of the elevator door, so the elevator door deflects the silica gel plate 2 outward during the closing process. When the elevator door is completely closed, the silica gel plate 2 is completely moved out of the elevator, and the silica gel plate 2 does not affect the normal operation of the elevator door.

[0043] It also includes a reinforcing bar 21 and a motor 22, the silica gel plate 2 is fixedly bound to one end of the reinforcing bar 21 near the side of the elevator door, the motor 22 is fixedly installed in the cavity 13, and the other end of the reinforcing bar 21 away from the silica gel plate 2 extends into the cavity 13 and is fixedly bound to the transmission shaft of the motor 22.

[0044] Working principle: when the trailer comes out of the elevator, the silica gel plate 2 blocks the light barrier 9, and the light barrier 9 feeds back information to the control module 9. After receiving the information, the control module 9 starts the motor 22 two minutes later, the motor 22 rotates to wind the reinforcing bar 21, and pulls the silica gel plate 2 to re-contact the elevator door. Then the motor 22 stops working.

[0045] The sliding groove 11 is internally arranged with a thin spring 111, the inner wall of the end of the sliding groove 11 away from the silica gel plate 2 is welded to one end of the thin spring 111, and the other end of the thin spring 111 is welded to the rod body of the vertical rod 6. When the rail 5 abuts against the elevator door, the thin spring 111 is lengthened. The thin spring 111 assists the thick spring 72 to reset. Under the joint action, the vertical rod 6 is reset.

[0046] The base 1 is welded with a protrusion 12 near the side of the elevator door, the protrusion 12 is used for hinging with the silica gel plate 2, and the base 1 is provided with a placing groove 15 on the side edge, and the light barrier module 9 is placed in the placing groove 15.

[0047] In summary, the automatic anti-collision safety auxiliary device for the elevator door of the factory area is provided with a base 1, a silica gel plate 2, a connecting sleeve 3, a rotating shaft 4, a railing 5 and a vertical rod 6. When the goods trailer enters the elevator, the silica gel plate 2 deflects and extrudes the contact rod 7, the contact rod 7 is connected through the gear 8 and the extension rod 61, the vertical rod 6 drives the railing 5 to rotate, so that the railing 5 is in contact with the elevator door. In this way, the purpose of blocking the closing of the elevator door is achieved, the collision between the elevator door and the trailer caused by the sudden closing of the elevator door is avoided, and the safety accident is avoided. The automatic anti-collision effect is achieved.

[0048] While embodiments of the application have been shown and described, it is to be understood that the embodiments described are merely divergences, modifications, replacements and variations of the embodiments, and the scope of the application is defined by the appended claims and their equivalents.
