Abstract
The utility model discloses a safety device of an elevator. The safety device comprises a cage and a hoistway, wherein a clamping slot is formed in the inner wall of the hoistway from top to bottom; a through hole is formed in the side part of the cage; a braking handle is hinged to the interior of the through hole; one end of the braking handle is positioned in the cage, and the other end of the braking handle is fixedly connected with a braking clamping block which is connected to the clamping slot in a sliding manner. When the elevator slides down due to a fault, the braking handle is downwardly pressed, the braking clamping block rises, and an angle is changed; a corner at the upper part of the rectangular braking clamping block generates friction with one side wall of a sliding chute, and an opposite corner at the lower part of the rectangular braking clamping block generates friction with the other side wall of the sliding chute, so that the sliding-down speed of the elevator can be reduced; a safety box is arranged outside the braking handle in the cage and can seal the braking handle to prevent the braking handle from being triggered during normal running of the elevator. The safety device is simple in structure and can be used conveniently and safely.
Description
Technical field
The utility model relates to a kind of elevator car safety.
Background technology
Progress and development along with the epoch, people's modernization day by day of living, the high building standing in great numbers makes elevator become the upper first-selected instrument downstairs of people, but the safety problem of elevator also becomes the problem that people pay close attention to day by day, elevator produces fault, downslide out of control, when serious, may injure life, cause any property loss, be the major hidden danger in people's daily life.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned defect, and a kind of elevator car safety that reduces elevator slip velocity when out of control is provided.
In order to solve the problems of the technologies described above, car and the hoistway of comprising of the present utility model, its constructional feature is to be provided with draw-in groove from top to bottom on the inwall of described hoistway, the sidepiece of described car is provided with through hole, in described through hole, be hinged with brake-applying handle, one end of described brake-applying handle is arranged in car, and the other end is connected with the braking fixture block being slidably connected in draw-in groove.
The diameter of described through hole is greater than the diameter of brake-applying handle.
The outside of described car inside brake handle is provided with the safety box that brake-applying handle can be sealed.
Two inside portions of described draw-in groove are connected with respectively elastic, can increase the friction between braking fixture block and draw-in groove.
Described braking fixture block is the width that rectangle and its width are less than draw-in groove.
Adopt the elevator car safety of such scheme compared with prior art to have the following advantages: hoistway inwall is provided with chute, the sidepiece handing-over of car has brake-applying handle, the other end of brake-applying handle is connected with the braking fixture block being slidably connected in chute, when elevator glides because of fault, by brake-applying handle to pressing down, braking fixture block rises and Angulation changes, one jiao of rectangle braking fixture block top is rubbed with a sidewall of chute, another sidewall of the relative angle of bottom and chute rubs, thereby reduces the slip velocity of elevator; The diameter of through hole is greater than the diameter of brake-applying handle, has certain space when brake-applying handle is moved up and down; The outside of car inside brake handle is provided with safety box, and safety box seals brake-applying handle, and while preventing that elevator from normally moving, brake-applying handle is touched, and the utility model is simple in structure, and safety easy to use.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the annexation schematic diagram of brake-applying handle and car.
The specific embodiment
As depicted in figs. 1 and 2, this elevator car safety comprises car 1 and hoistway 2, on the inwall of hoistway 2, be provided with draw-in groove 3 from top to bottom, the sidepiece of car 1 is provided with through hole 9, in through hole 9, be hinged with brake-applying handle 4, through hole 9 sidewalls are provided with blind hole, and brake-applying handle 4 is provided with the through hole that can pass for hinge, hinge passes through hole and coordinates with blind hole, realizes the hinged of brake-applying handle 4 and car 1 sidepiece.The diameter of through hole 9 is greater than the diameter of brake-applying handle 4, when being moved up and down, brake-applying handle 4 there is certain space, one end of brake-applying handle 4 is arranged in car 1, and the other end is connected with the braking fixture block 5 being slidably connected in draw-in groove 3, and brake-applying handle 4 is affixed with the part that braking fixture block 5 stretches out draw-in groove 3.Braking fixture block 5 is the width that rectangle and its width are less than draw-in groove 3, brake-applying handle 4 is when pressing down, braking fixture block 5 rises in draw-in groove 3, and its angle also changes, one jiao of braking fixture block 5 tops is rubbed with a sidewall of chute, another sidewall of the relative angle of bottom and chute rubs, thereby reduces the slip velocity of elevator.Two inside portions of draw-in groove 3 are connected with respectively elastic 6, and elastic 6 can increase the friction between braking fixture block 5 and draw-in groove 3, further reduce the slip velocity of elevator.
The outside of car 1 inside brake handle 4 is provided with the safety box 7 that brake-applying handle 4 can be sealed, and install bin 7 is provided with chamber door, and when safety box 7 can prevent that elevator from normally moving, people touch brake-applying handle because of carelessness, affect the normal operation of elevator.
When elevator normally moves, braking fixture block 5 is parallel with the two side of draw-in groove 3, and along draw-in groove 3 straight line up-and-down movements; Elevator breaks down while gliding, open chamber door, to brake hand, 4 press down, and make to brake fixture block 5 and rise and tilt, and two diagonal angles of braking fixture block 5 rub respectively at the two side of draw-in groove 3, and it is larger to press down angle, its friction force is larger, can reduce rapidly the slip velocity of elevator, ensures the life security of people in car.
Draw-in groove 3 in the present embodiment and brake-applying handle 4 are arranged on a sidepiece of elevator, and draw-in groove 3 and corresponding brake-applying handle 4 with it also can be set respectively in the both sides of elevator, can further reduce lift slide speed.
The utility model is not limited to the above-mentioned specific embodiment, and those skilled in the art, not departing under the prerequisite of spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
