Background technology
Modern city rhythm is constantly accelerated, and living standard is more and more higher, and traffic is also more and more convenient, and high-rise residential building, office building are rised sheer from level ground in succession, and elevator also becomes the indispensable part of people's daily life.Elevator is the same with other maneuver classes products, and Long-Time Service is all its function of loss to break down.Elevator arrives after the floor car door of specifying opens, and it is one of common fault of elevator that car continues to rise or decline, and causes personnel to be blocked by elevator dead event of suffocating thus happening occasionally.Therefore, how preventing car door from opening rear car and continue to rise or decline, is the problem that those skilled in the art pay close attention to always.
Summary of the invention
The utility model object is to provide a kind of fender guard preventing accidental movement of elevator cage.
For achieving the above object, the utility model takes following technical proposals:
The fender guard preventing accidental movement of elevator cage described in the utility model, comprise perpendicular to the horizontally hinged rotating shaft on car back timber of car door link plate, described rotating shaft two ends are fixed with the first swing arm and the second swing arm along rotating shaft radial direction respectively; Described first swing arm end be plugged in by bearing pin be arranged on car door link plate top guide channel plate chute in, described chute is made up of upper horizontal guide slot section, tiltedly guide groove section and lower horizontal guide slot section from left to right; The end of described second swing arm is hinged with hook connecting rod, and described hook connecting boom end and inverted L-shaped are linked up with hinged; Armstand and the car back timber of described inverted L-shaped hook are hinged, the transverse arm of inverted L-shaped hook is hinged with riser, the edge described riser being positioned at described armstand side offers gap, touch switch is provided with in described gap, described touch switch is series in the safety return circuit of elevator, for cutting off actuator electrical source circuit, be fixed with the braking link plate linked up with transverse arm with inverted L-shaped and match in the side being positioned at every layer of elevator rail.
The armstand end of described inverted L-shaped hook is hinged with the mount pad be connected with car back timber, described mount pad is fixed with unhook detector switch.
The utility model advantage is to realize to stop elevator when arriving the floor of specifying, and car door opens the phenomenon that rear car continues to rise or decline, and reaches the security purpose that available protecting takes elevator personnel.

Fig. 1 is structural representation of the present utility model.
Fig. 2 is the I portion structure for amplifying schematic diagram of Fig. 1.
Fig. 3 is the reference view after rotating shaft described in the utility model, the first swing arm, the second swing arm assembling.
Detailed description of the invention
As Figure 1-3, the fender guard preventing accidental movement of elevator cage described in the utility model, comprise perpendicular to the horizontally hinged rotating shaft 3 on car back timber 2 of car door link plate 1, described rotating shaft 3 two ends are fixed with the first swing arm 4 and the second swing arm 5 along rotating shaft radial direction respectively; Described first swing arm 4 end be plugged in by bearing pin 19 be arranged on car door link plate 1 top guide channel plate 6 chute in, described chute is made up of upper horizontal guide slot section 7, tiltedly guide groove section 8 and lower horizontal guide slot section 9 from left to right; The end of described second swing arm 5 is hinged with hook connecting rod 10, and described hook connecting rod 10 end and inverted L-shaped are linked up with hinged; Armstand 11 lower end of described inverted L-shaped hook is hinged with the mount pad 17 be fixedly connected with car back timber 2, mount pad 17 is fixed with unhook detector switch 18; The transverse arm 12 of inverted L-shaped hook is hinged with riser 13, the edge described riser 13 being positioned at described armstand 11 side offers gap, touch switch 14 is provided with in described gap, described touch switch 14 is series in the safety return circuit of elevator, for cutting off actuator electrical source circuit, be fixed with the braking link plate 16 linked up with transverse arm 12 with inverted L-shaped and match in the side being positioned at every layer of elevator rail 15.
Utility model works principle is summarized as follows:
When lift car normal door, being moved left by car door link plate 1 drives the guide channel plate 6 at car door link plate 1 top to left movement, the bearing pin 19 of the first swing arm 4 is moved along the upper horizontal guide slot section 7 of chute, when car door link plate 1 reaches certain distance, the bearing pin 19 of the first swing arm 4 enters oblique guide groove section 8, at this moment will make the first swing arm 4, rotating shaft 3, second swing arm 5 rotates along anticlockwise direction, the transverse arm 12 simultaneously driving hook connecting rod 10 to promote inverted L-shaped hook moves in braking link plate 16 lock hole being fixed on elevator rail 15 side; When the bearing pin 19 of the first swing arm 4 is after oblique guide groove section 8 has moved, the transverse arm 12 that inverted L-shaped will be made to link up with inserts in the lock hole of braking link plate 16; When car door link plate 1 continues to open left, the first swing arm 4 is moved along lower horizontal guide slot section 9, and at this moment the first swing arm 4 no longer swings, until car door link plate 1 is opened left completely.Now, the movement if car meets accident, when car moves a certain distance, braking link plate 16 will clash into the riser 13 be hinged on inverted L-shaped hook transverse arm 12, elevator safety loop and drive power supply disconnect by touch switch 14 action be arranged in riser 13 gap, and making elevator be in faulty condition can not restart; If car continues accidental movement, the transverse arm 12 of inverted L-shaped hook makes car enter locking state up and down by braking link plate 16, reach and avoid car to cause casualties the generation of accident because of accidental movement, now elevator can not be activated again, must be resetted by professional.
When lift car at closing time, car door link plate 1 moves right and drives guide channel plate 6 to move, the bearing pin of the first swing arm 4 is moved along lower horizontal guide slot section 9, when car door link plate 1 closes certain distance, and car not because of accidental movement by locked time, the bearing pin of the first swing arm 4 enters oblique guide groove section 8, at this moment the first swing arm 4 will be made, rotating shaft 3, second swing arm 5 is rotated clockwise, the transverse arm 12 simultaneously driving hook connecting rod 10 to pull inverted L-shaped to link up with departs from the lock hole of braking link plate 16, when the first swing arm 4 is after oblique guide groove section 8 has moved, inverted L-shaped will be made to link up with and to get back to original position, the unhook detector switch 18 be now arranged on inverted L-shaped hook mount pad 17 is touched that (unhook detector switch 18 can be connected on the control loop of car door lock switch, be used for detecting this device and whether depart from car locking state), send unhook signal.Car door link plate 1 car door that continues to move right inwardly closes, and the bearing pin of now the first swing arm 4 runs along upper horizontal guide slot section 7, and at this moment the first swing arm 4 can not swing again, until car door link plate 1 is closed completely.
