DETAILED DESCRIPTION

[0026] The utility model will be further described below in combination with the drawings and specific embodiments.

[0027] For example, Figures 1 to 4The diagram shows an electric flip-door for a construction hoist cage, comprising an upper door 1, a flip-door 2, a push rod 5, a linkage rope device 3, a folding railing 4, an opening limit switch 6, a closing limit switch 7, a safety light curtain 9, a human recognition camera 8, and a control system. The upper door 1 and the flip-door 2 are both installed at the exit of the cage 10. The upper door 1 can move up and down along the door frame of the cage 10. The flip-door 2 is hinged to the threshold of the cage 10 and can rotate around a connecting shaft. Linkage rope devices 3 are provided on both sides of the upper door 1 and the flip-door 2. The folding railing 4 connects... The push rod 5 is connected to the flip door 2 and the cage 10. It is installed between the cage 10 and the flip door 2, and is hinged to the cage. Its drive end is hinged to the side of the flip door 2. The opening limit 6 and closing limit 7 are installed on the cage and connected to the control system. The upper door 1 has a trigger block 11 that triggers the opening limit 6 when the door is opened and the closing limit 7 when the flip door 2 is closed. The safety light curtain 9 is installed on both sides of the flip door 2, and the human figure recognition camera 8 is installed inside the cage. Both the safety light curtain 9 and the human figure recognition camera 8 are connected to the control system. The push rod 5 is controlled by the control system and can extend and retract. When extended, it pushes the flip door 2 to rotate and open, at which time the upper door 1 opens upwards; when retracted, it pulls the flip door 2 to rotate and close, at which time the upper door 1 closes downwards.

[0028] like Figure 5 As shown, the linkage rope device 3 includes a steel wire rope 31 and a fixed pulley 32. One end of the steel wire rope 31 is connected to the top of the flip door 2, and after passing through the fixed pulley 32 at the top of the door frame, it is connected to the upper half door 1, so that when the flip door 2 is rotated and opened, it drives the upper half door 1 to move up and down.

[0029] like Figure 6 The folding railing 4 is an "F"-shaped linkage frame, including an upright 41, an upper horizontal bar 42, and a middle horizontal bar 43. Each node between the upright 41, the upper horizontal bar 42, and the middle horizontal bar 43 can rotate. The bottom end of the upright 42 is hinged to the side of the flip door 4, and the upper horizontal bar 42 and the middle horizontal bar 43 are respectively hinged between the cage door frame and the upright 41.

[0030] When the door is opened, the folding railings unfold into an "F" shape.

[0031] When the door is closed, the folding railings fold up into an "I" shape and are stored between the flip-up door and the hanging cage door frame. Figure 7 As shown, there is a right-angled connecting structure on the left side of the middle crossbar 43, so the upper crossbar 42 and the middle crossbar 43 are staggered and can overlap when folded.

[0032] In the above technical solution, the door opening limit 6 is installed at the top of the door frame of the cage 10. There is a door opening stop block on the upper half door 1. When the upper half door 1 is opened to the position, the door opening stop block triggers the door opening limit and stops the door from opening.

[0033] In the above technical scheme, the door closing limit 7 is installed at the middle position of the cage door frame and is in contact with the door closing block 11 on the flap door 2, when the flap door 2 is closed to the position, the door closing block triggers the door closing limit 7 to stop closing the door.

[0034] As shown in the drawings, the safety light curtain 9 is a pair of long strip-shaped rods, which are light curtain member one 91 and light curtain member two 92, respectively installed on both sides of the flap door, and a light curtain is formed between the two rods, which can detect whether there is an object on the flap door. Figure 8 As shown in the drawings, the safety light curtain 9 is a pair of long strip-shaped rods, which are light curtain member one 91 and light curtain member two 92, respectively installed on both sides of the flap door, and a light curtain is formed between the two rods, which can detect whether there is an object on the flap door.

[0035] Figure 9 As shown in the drawings, the human recognition camera 8 is installed at the top of the cage 10. The upper space area of the flap door can be observed, and whether there is a person can be identified through software.

[0036] The above is only the preferred specific implementation of the present application, but the protection scope of the present application is not limited to this, any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.​
