Description
Technical Field
The invention belongs to the technical field of elevator safety facilities, and particularly relates to a safety speed reducing device of an inclined elevator.
Background
Technical information of arranging safety reduction devices on an upper and a lower vertical running elevators can be found in published Chinese patent documents, and typical examples are 'an elevator with a parachute' recommended by the invention patent publication No. CN105752803A and 'a safety type elevator car special for a residential district' provided by the invention patent publication No. CN 105621207A. The former technical scheme in the two patents is as follows: the parachute box is arranged at the top of the car, a parachute is arranged in the parachute box, the width of the well is larger than the diameter of the parachute, the bottom of the parachute is fixed on the top wall outside the car, and a switch of the parachute is arranged in the car. The technical effect is as described in the 0007 paragraph of the specification: when the elevator breaks down, the parachute can be opened, the falling speed of the lift car is reduced, the accident damage degree is reduced, and the elevator is particularly suitable for high-rise buildings.
However, the detailed structure of the whole safety deceleration device including the parachute is not disclosed in the whole specification of the aforementioned CN105752803A, for example, how to open the parachute in time when the elevator fails, how to reliably control the parachute in a parachute box (called a parachute box in the patent) in a standby state, how to give a signal to the safety deceleration device by an elevator controller at the moment when the elevator falls down, how to ensure that the parachute can rapidly exit the parachute box, and the like. In addition, it seems undesirable that CN105752803A places a switch for opening the parachute box in the car, because if the car is inadvertently touched, abnormal activation may occur, which not only gives false surprise to passengers, but also causes trouble to the elevator management side. In addition, when danger happens, namely when the car is out of control and falls down, the switch is manually operated, and at least the following defects exist: since the car is dropped, usually without any indication, the car may fall when the passenger does not respond, and even if the passenger responds, the car cannot be operated in the first time because the manual switch has time difference, and because the passenger is usually in a high tension and panic state in the dropping process of the elevator and does not immediately make the action of pressing the switch.
In addition, since the above-mentioned CN105752803A and CN105621207A are both directed to vertical ascending and descending elevators, they do not suggest themselves to inclined elevators, and CN1056210207A also has the above-mentioned disadvantages of CN 105728203A.

When accidents occur, such as the traction rope 1 is broken and the traction mechanism 9 is out of control, the car body 1 can quickly slide (slide downwards) on the pair of inclined guide rails 21, at the same time, the speed of the tachometer wheel 82 is collected by the tachometer wheel speed signal collector 84 and fed back to the elevator controller, the power supply of the electromagnetic coil 62 of the locking rod control mechanism 6 is switched on by the elevator controller, namely the electromagnetic coil 62 is electrified, the iron core 63 retracts towards the electromagnetic coil 62 under the action of the counter force of the iron core spring 64, the locking tongue 631 of the iron core 63 withdraws from the locking tongue cavity 441, at the same time, the sliding push plate 41 is pushed to simultaneously move towards the door 32 along the restoring force of the group of springs 5 in the compressed and energy-stored state on the front box wall, the lower sliding grooves 33a and 33b and the rear box wall, therefore, the pair of upper connecting rods 43 and the pair of lower connecting rods 44 push the first door 321 and the second door 322, so that the first door 321 and the second door 322 are opened, the parachute 7 which is in a folded state is opened quickly, the running speed of the car body 1 is remarkably reduced, and accidents are avoided.
In conclusion, the technical scheme provided by the invention overcomes the defects in the prior art, successfully completes the invention task and truly realizes the technical effects of the applicant in the technical effect column.
