Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1-4, an elevator emergency rescue device comprises a connecting plate 1 and a non-electric lifting device, wherein the connecting plate 1 is arranged above a car 3 of an elevator and is connected with the car 3 through the non-electric lifting device, and the top surface of the connecting plate 1 is connected with a lifting hoisting rope 4 of the elevator.
An embodiment of the utility model, as shown in fig. 4, when the elevator stops between two floors because of unexpected situation, the passenger is stranded in car 3 of elevator. At this time, the passenger in the car 3 can manually open the elevator door 8 according to the operation guide placed in the car 3, and the passenger can escape by manually opening the floor door 9 before the car 3 is lowered to the floor door 9 of the nearest lower floor by manually driving the non-electric power elevating device.
The non-electric lifting device is a hydraulic jack 2, a rod part 21 of the hydraulic jack 2 is vertically and fixedly connected to the connecting plate 1, and an operation end 22 of the hydraulic jack 2 is fixedly connected to a car bottom 31 of the car 3. The passenger repeatedly operates the lever handle of the operation end 22 to extend the rod part 21 of the hydraulic jack 2, and the car 3 descends along with the extension of the rod part 21. When the emergency situation of the elevator is over, the oil drain valve of the operation end 22 is opened, the rod part 21 is retracted, and the car 3 returns to the normal position.
In general, the hydraulic jack 2 is housed and hidden inside the car wall 32 of the car 3 so that it does not affect the normal passenger carrying space of the car 3. And a door 33 is arranged on the car wall 32, and the operating end 22 of the hydraulic jack 2 is covered and hidden by the door 33 under the normal state, and the door 33 can be opened to operate the hydraulic jack 2 when necessary.
In addition, in order to avoid hiding the hydraulic jack 2 in the car wall 32 of the car 3, the hydraulic jack 2 is only connected with one side of the car 3, so that the stress on the hydraulic jack 2 is unbalanced, the performance and the service life of the hydraulic jack 2 are affected, and new insecurity is generated. At least two hydraulic jacks 2 can be arranged, and the center of gravity of all the hydraulic jacks 2 is located in the middle of the car 3, so that stress balance between the hydraulic jacks 2 and the car 3 is achieved. The hydraulic jacks 2 are generally arranged not to exceed three, and the number is too large, so that the stability is good, but the operation is affected.
As a preferred embodiment, a protection hoisting rope 5 is further connected between the connection plate 1 and the car 3, and the protection hoisting rope 5 connects the auxiliary hoisting machine 6 on the top of the connection plate 1 and the car 3. The protection hoisting rope 5 is additionally arranged to be used as a protection mechanism when the non-electric lifting device fails, so that the separation of the lift car 3 and the connecting plate 1 is avoided. When the car 3 is lowered by manually operating the non-electric power elevating device, the protection hoisting rope 5 is naturally extended as the car 3 is lowered. When the car 3 is returned to the raised state after the recovery from the abnormal state, the auxiliary hoisting machine 6 is started to retract the protection hoisting rope 5. Wherein the thread protecting the hoisting ropes 5 the largest should not exceed the height of one floor.
In a simple concrete structure of a protection mechanism for protecting a hoist rope 5, a top surface of a connection plate 1 is provided with a through hole 11, the protection hoist rope 5 passes through the through hole 11, and both ends of the protection hoist rope are connected to an auxiliary hoist 6 and a top portion of a car 3, respectively.
In one preferable specific structure of the protection mechanism for protecting the hoist rope 5, the protection hoist rope 5 is wound around the auxiliary traction machine 6, and both ends of the protection hoist rope are connected to both sides of the car 3. The force applied to the protection hoisting rope 5 is reduced by contacting and dispersing the force-applying points of the two ends of the protection hoisting rope 5 with the car 3. And the fixed pulley 7 is arranged on the path of the protection hoisting rope 5, so that the force borne by the protection hoisting rope 5 is further buffered, the space where the protection hoisting rope 5 is positioned can be adjusted, and the contact with the car 3 and the edge of the connecting plate 1 is avoided.
The above embodiments of the present invention are not right the utility model discloses the limited protection scope, the utility model discloses an embodiment is not limited to this, all kinds of basis according to the above-mentioned of the utility model discloses an under the above-mentioned basic technical thought prerequisite of the utility model, right according to ordinary technical knowledge and the conventional means in this field the modification, replacement or the change of other multiple forms that above-mentioned structure made all should fall within the protection scope of the utility model.
