[0025] Example
[0026] like Figure 1-4As shown, the present embodiment provides a car roof with a fan 3 and a safety window 2, comprising a car roof panel 1, wherein the car roof panel 1 is fixedly mounted on the top of the elevator and used as the elevator car roof, wherein the side of the car roof panel 1 located inside the elevator is the front side, and the side located outside the elevator car is the back side; a circular safety window 2 is provided in the middle of the car roof panel 1, and a rotating assembly 4 and a lock body assembly 5 are respectively provided on the back side of the car roof panel 1 located on the opposite sides of the safety window 2, and a fan 3 is provided on the back side of the car roof panel 1, wherein the fan 3 covers the safety window 2, and the fan 3 is embedded in the safety window 2, and the surface of the fan 3 is flush with the front side of the car roof panel 1, and the whole is not raised and is beautiful; the side of the fan 3 is connected to the rotating assembly 4, and the fan 3 can rotate along the rotating assembly 4 to make the fan 3 leave the safety window 2, thereby opening the safety window 2, and the lock body assembly 5 is used to clamp the fan 3, and the lock body assembly 5 needs to be opened first before the fan 3 can be rotated to open the safety window 2.
[0027] Specifically, the rotating assembly 4 includes an articulated seat 41 fixedly connected to the back of the car top panel 1 by bolts, a rotating shaft 42 is rotatably connected to the articulated seat 41, and a rotating seat 43 is fixedly connected to the side of the fan 3 by bolts, and the rotating shaft 42 is arranged through the rotating seat 43. If the safety window 2 needs to be opened inside the elevator car, after opening the lock body assembly 5, the fan 3 is pushed, and one end of the fan 3 can rotate around the rotating shaft 42 as an axis, thereby opening the safety window 2.
[0028] In addition, a handle 31 is fixedly connected to one side of the fan 3 near the lock assembly 5. If the safety window 2 needs to be opened outside the elevator car, the fan 3 can be pulled by the handle 31 after the lock assembly 5 is opened, so that one end of the fan 3 can rotate around the rotating shaft 42, thereby opening the safety window 2.
[0029] Specifically, the lock body assembly 5 includes a lock box body 51, which is fixedly installed on the back side of the car top panel 1 by bolts, and a lock tongue 52 is movably connected in the lock box body 51, and one end of the lock tongue 52 can extend out of the lock box body 51 and extend to the top of the fan 3, thereby limiting the fan 3 and locking the fan 3 so that it cannot rotate to open the safety window 2, or move into the lock box body 51 to release the restriction on the fan 3, so that the fan 3 can rotate to open the safety window 2, and one end of the lock tongue 52 is welded or integrally formed with a manual pull ring 53, and one end of the manual pull ring 53 passes through the lock box body 51 and extends to the outside of the lock box body 51. The rescue personnel open the floor door through the upper layer of the car, and then descend to the back side of the car top panel 1. The lock tongue 52 can release the restriction on the fan 3 by pulling the manual pull ring 53. At this time, rotating the fan 3 can open the safety window 2 to rescue the people in the car.
[0030] Furthermore, a reset spring 54 is sleeved on the manual pull ring 53, and two ends of the reset spring 54 are respectively disposed against the lock tongue 52 and the lock box body 51. After the manual pull ring 53 is released, the lock tongue 52 is reset by the elastic force of the reset spring 54.
[0031] Specifically, a triangular lock 55 is embedded in the side of the lock box body 51, and a lock core 56 is rotatably connected inside the triangular lock 55. One end of the lock core 56 is arranged inside the lock box body 51, and a paddle 57 is fixedly connected to one end of the lock core 56 close to the lock tongue 52. A raised stopper 58 is arranged on the side of the lock tongue 52 close to the paddle 57. The paddle 57 is arranged against the stopper 58, and the triangular lock 55 is arranged through the car top panel 1. When the maintenance personnel or the installer needs to open the safety window 2 inside the car, the triangular lock 55 is rotated by a tool, so that the lock core 56 of the triangular lock 55 rotates to drive the paddle 57 to rotate, and when the paddle 57 rotates, it pushes the stopper 58 to move, thereby driving the lock tongue 52 to move, so as to achieve unlocking.
[0032] Furthermore, one end of the lock tongue 52 is an arc surface structure. When the safety window 2 needs to be closed, the fan 3 rotates to push the arc surface of the lock tongue 52, forcing the lock tongue 52 to contract, thereby closing the safety window 2, and after the edge of the fan 3 moves into place, the lock tongue 52 is reset by the reset spring 54.
[0033] Specifically, it also includes a detection switch 61, the car top panel 1 is fixedly connected with a switch fixing plate 62, the detection switch 61 is fixedly connected to the switch fixing plate 62, the side of the fan 3 is fixedly connected with a switch pressing plate 63, and the switch pressing plate 63 is set against the detection end of the detection switch 61. When the safety window 2 is closed by the fan 3, the switch pressing plate 63 on the fan 3 presses the detection end of the detection switch 61, and the detection switch 61 detects that the fan 3 is in a closed state; if the fan 3 rotates to open the safety passage, the switch pressing plate 63 leaves the detection switch 61, and the detection switch 61 can be used to determine that the safety window 2 is in an open state; the detection switch 61 is connected to the elevator control system, and if it is detected that the safety window 2 is in an open state, the elevator control system receives a signal from the detection switch 61, cuts off the power source, and prevents the elevator car from moving.
[0034] Furthermore, the car top panel 1 is provided with mounting holes around it, and the mounting holes are embedded with lighting lamps 7. The lighting lamps 7 are used to illuminate the interior of the car and provide a light source.
[0035] The working principle of this utility model:
[0036] Escape principle: (This item is applicable to professionals, such as elevator maintenance and installation personnel):
[0037] 1. When the elevator breaks down and you cannot escape by opening the door;
[0038] 2. You can borrow a suitable object to the upper part of the car, use the triangular key to open the lock, push the fan 3 to form a passage for the safety window 2, and at the same time the detection switch 61 is automatically disconnected, and a signal is sent to the elevator control system to disconnect the power source.
[0039] 3. Go to the top of the car and rescue yourself through the upper door.
[0040] Rescue principle:
[0041] 1. When the elevator breaks down, it is impossible to open the door or move the car for rescue.
[0042] 2. Rescuers open the door on the upper floor of the car and reach the top of the car.
[0043] 3. After the rescue personnel manually unlock the door and turn on the fan 3, a passage for the safety window 2 is formed on the top surface of the car.
[0044] 4. Rescuers lower the ladder to carry out rescue.
