Specific embodiment
The present invention is described in further detail below in conjunction with Figure of description.
As shown in Figure 1-2, device is prevented under a kind of home lift of the invention, the lower prevention device realizes that well need not be entered
Road, you can remote operation, really meets the requirement of home lift manufacture and installation specification.Including being fixedly installed in elevator pit
Operational module, be fixedly installed on elevator hoistways inwall or outer wall and operation mould that easily operated personnel operate outside hoistway
The transmission module of block, connection operational module and operation module.
Operational module includes base 1, push rod 2, back-moving spring 3, the contact switch 4 that is arranged on the lateral surface of base 1, push rod
2 bottom is rotatably assorted with base 1, and one end of back-moving spring 3 is connected by upper connecting pole 5 with push rod 2, back-moving spring 3 it is another
One end is connected by lower connecting pole 6 with base 1, wherein, base 1 is U-shaped, including integral type set base plate and be arranged on base plate
The side wall of both sides, the bottom of push rod 2 is connected by screw rod with the two side of base 1, and the top of push rod 2 is provided with yielding rubber
11。
Operation module includes the action bars 8 that support 7 and support 7 are rotatably assorted, and is fixedly installed on the Z-type gear of the upper end of support 7
Plate 9；Support 7 includes vertically disposed first support plate 71 and second support plate 72, and baffle plate 9 is fixedly installed on first support plate 71
Upper end, integral type is provided with installing plate 73 on second support plate 72, and mounting hole 74 is provided with installing plate 73, action bars 8
One end is rotatably assorted with the lower end of first support plate 71, and this is rotatably assorted can be using forms such as screw rod connection or Axle Parts.
Transmission module includes pulley assembly and steel wire rope 10, and one end and the action bars 8 of steel wire rope 10 fix, the other end of steel wire rope 10 and
Upper connecting pole 5 is fixed, and pulley assembly includes the first pulley 12, the pulley of second pulley 13 and the 3rd that are connected with the side wall of base 1
