Safety deceleration device for inclined elevator

Abstract

A safety deceleration device for an inclined elevator, the inclined elevator includes a car body, and the safety deceleration device includes a parachute box, which is fixed in the middle of the side of the car body facing the upward direction of a pair of inclined guide rails; the box door is opened The mechanism is located in the parachute box cavity and is hinged with the box door; a set of springs is located in the parachute box cavity and one end is supported on the wall of the side of the parachute box cavity facing the mouth of the cavity, and the other end is supported on the box door opening mechanism on; the locking rod control mechanism is fixed on the cavity wall of the parachute box cavity on the side opposite to the cavity opening and corresponds to the box door opening mechanism; Between the doors, and the parachute control rope of the parachute reaches the cavity wall on the side of the parachute box cavity facing the opening, and the opening faces the upward direction of a pair of guide rails. The parachute can be released smoothly; the automatic release of the parachute is guaranteed at a fast speed; misoperation is eliminated and the intensity of management work is reduced.

Description

technical field [0001] The invention belongs to the technical field of elevator safety facilities, and in particular relates to a safety deceleration device for an inclined elevator. Background technique [0002] The technical information on setting up the safety deceleration device on the vertical elevator can be seen in the published Chinese patent documents, such as "a kind of elevator with a parachute" recommended by the invention patent publication number CN105752803A and the invention patent publication number CN105621207A. "A special elevator car for a security-type community". The technical scheme of the former in these two patents is: be provided with parachute box on the car top, be provided with parachute in the parachute box, the width of hoistway is greater than the diameter of parachute, the bottom of parachute is fixed on the car outer top wall, parachute The switch is located in the car. The technical effect is as described in paragraph 0007 of its manual: ...

AI Technical Summary

Problems solved by technology

[0003] However, looking at the full text of the aforementioned CN105752803A specification, I have not seen the specific structure of the entire safety deceleration device including the parachute, such as how to open the parachute in time when the elevator fails, and how to reliably control the parachute in the standby state. In the box (the patent is called the parachute box), how the elevator controller sends a signal to the safety deceleration device at the moment the elevator falls, how to ensure that the parachute can quickly escape from the parachute box, etc.

In addition, CN105752803A seems to be inadvisable to set the switch for opening the parachute box in the car, because once the occupant unintentionally touches it, abnormal activation will occur, which will not only cause false alarm to the occupants, but also bring trouble to the elevator management

In addition, when the car falls out of control when the danger occurs, at least the following disadvantages exist in the manual operation of the switch: because the car falls usually without warning in an instant, it may have fallen before the occupant reacts. And because even if the occupant responds, there is a time difference between manually touching the switch, so it cannot be effective in the first time, and because the occupant is often in a state of high tension and panic during the elevator's descent, and will not immediately press the button. The action of moving the switch

[0004] In addition, since the aforementioned CN105752803A and CN105621207A are all aimed at vertically ascending and descending elevators, they are not instructive for oblique elevators, and CN1056210207A also has the aforementioned shortcomings of CN105728203A
