Detailed Description
The present invention will be further described with reference to the accompanying drawings.
An industrial elevator safety landing door, as shown in fig. 1, 2 and 3, comprises a door frame 1; a door leaf 2 is arranged inside the door frame 1 in a rotating manner; the opening direction of the door leaf 2 is a direction far away from the lifter 9; a connecting rod mechanism 4 is arranged on one side of the door frame 1 facing the lifter 9; the top of the door frame 1, which is back to the side of the lifter 9, is rotatably connected with a baffle plate 3; the lowest end of the overturning path of the baffle 3 correspondingly interferes with the opening path of the door leaf 2; the connecting rod mechanism 4 is in control connection with the baffle 3; a car latch 8 is arranged on one side of the lifter 9 facing the door frame 1; the lifting path of the car collision iron 8 corresponds to the position of the connecting rod mechanism 4; when the lifter 9 moves to a position right opposite to the door frame 1, the car collision iron 8 touches the connecting rod mechanism 4 and correspondingly drives and controls the baffle 3 to be turned upwards to contact with the door leaf 2 in a limited manner;
through the cooperation of the car latch 8 and the link mechanism 4, the door leaf 2 can be ensured to be in a locked state by the baffle 3 when the elevator does not move to be aligned with a landing door, so that the safety of the elevator in use is obviously improved.
The door frame 1 is provided with a first protection switch 6, and the first protection switch 6 can be specifically matched with an infrared sensor and is used for sensing whether one side of the door leaf 2, which is far away from the rotating shaft, is in the door frame 1 or not, so that a control effect of corresponding on or off is achieved; the first protection switch 6 is electrically connected to the integral power supply circuit of the lifter 9; when the door leaf 2 is at the closed position, the first protection switch 6 is in a communicated state; when the door leaf 2 is opened, the first protection switch 6 is in a disconnected state; in the use of lift, the lift at first aligns with the landing door, and car bumps iron 8 and triggers link mechanism 4 and opens the action of baffle 3, and the inside personnel of lift open door leaf 2 afterwards and walk out the lift, and at personnel's removal in-process, first anti-skidding switch 6 corresponds and is in the off-state, then the lift can not be because of mistake touch switch and half way sudden movement to security when having promoted personnel's business turn over greatly.
A handle 5 is arranged on one side of the door frame 1, which is back to the lifter 9; the handle 5 is connected with the connecting rod mechanism 4 and correspondingly controls the response state between the connecting rod mechanism 4 and the car latch 8, namely whether the connecting rod mechanism 4 responds to the touch of the car latch 8 to open the baffle 3 is controlled, and the connection and the matching between the connecting rod mechanism and the baffle 3 can be interrupted; in the floor that does not use the lift, the staff cuts off the cooperation between link mechanism 4 and the car iron 8 through handle 5 to can prevent that the lift from making door leaf 2 lose the restraint when passing through, thereby can be according to the locking state of specific user demand dynamic adjustment landing door, its practicality and security are higher.
A handle 51 is arranged on one side of the door frame 1 facing the lifter 9; the handle 51 and the handle 5 share a rotating shaft, and the handle rotate synchronously, so that personnel in the elevator can conveniently recover the matching between the connecting rod mechanism 4 and the car latch 8 at any time, and the personnel can conveniently and flexibly enter and exit the elevator, thereby realizing the bidirectional control of the locking state of the landing door.
A second protection switch is arranged in the lifter 9; the second protection switch is electrically connected with a control panel power supply circuit arranged in the lifter 9; when the car door of the lifter 9 is closed, the second protection switch is in a communicated state; when the car door of the lifter 9 is opened, the second protection switch is in an off state; the mode that the operating principle of second protection switch can adopt the infrared sensor similar with first protection switch to trigger, and its specific control circuit board can directly purchase the acquisition, switches control panel's power supply through the on off state who utilizes the sedan-chair door to avoid under the sight such as transport thing the mistake and touch lift inside control button, thereby can further promote the safety in utilization of lift again.
In addition, as shown in fig. 4, the inner side and the outer side of the door leaf 2 are also obliquely provided with the force-borrowing rods 21, so that on one hand, the door leaf 2 can be reinforced, and on the other hand, the force-borrowing rods can be held by workers when the door leaf 2 is pushed and pulled, and compared with the traditional door handle, the door handle has the advantages that the vertical space is saved, the elevator path can be closer to a landing door, the gap width is reduced, and stumbling is avoided; the surface of the force-aid rod 21 is wrapped with heat insulation materials such as plastic shell layers and the like, so that the high and low temperatures on the surface of equipment during outdoor operation can be relieved, and the palm of a worker is protected from being frostbitten and scalded.
The above description is only a preferred embodiment of the present invention, and it should be noted that: for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention.
