number of patent application is CN201120350578.1, the applying date is that the Chinese utility model patent on September 19th, 2011 discloses a kind of mechanical prevention device for domestic elevator, it comprises the L shape connecting panel that is fixed on cage guide on one side, the another side inboard of L shape connecting panel is installed with the flute profile base, the inside of base is provided with notch and base notches flute profile swing arm in opposite directions, hinged through S. A. between base and swing arm, also be connected through elastic mechanism between base and swing arm, elastic mechanism is arranged on the top of S. A., the swing arm upper end is installed with energy disperser, the swing arm lower end is wedge shape, be installed with junction button on the swing arm inwall, junction button is connected with the spanner that declutches of restriction swing arm turned position.This utility model is switched between normal condition and blocked state by declutch spanner controller buffer and swing arm simultaneously, makes it easy to operate simple.But it also has weak point, the mechanical stopping device of this utility model, its complex structure, bulky, make, install all very difficult, poor stability, and, need to take very large space in the time of installation, and in home lift, the height of a lot of floors is not very high, and tunnel dimension is less, does not have the space to install.
The utility model content
The purpose of this utility model is for the deficiencies in the prior art part, and a kind of mechanical prevention device for domestic elevator is provided, and it is simple in structure, volume is little, is convenient to install, and the space that takies in the time of installation is little, and is safe.
In order to solve the problems of the technologies described above, the technical solution of the utility model is as follows: a kind of mechanical prevention device for domestic elevator, comprise adapter plate, home switch, operating switch, laterally steering section is installed on described adapter plate, in described laterally steering section, the slip lance is installed, be fixed with on described slip lance and hit bow, a described part of hitting bow is used for matching with described home switch and described operating switch between described home switch and described operating switch.
mechanical stopping device of the present utility model, adopt the slip lance, laterally steering section, with oscillating rod type holdout device in the past, become the drawing and pulling type holdout device, make whole holdout device volume significantly reduce, structure is very compact, be convenient to install, dismounting, installation takes up room little, can be installed on request the hoistway arbitrary height, structural strength is high, safety is good, when in use, this mechanical stopping device is in working position, stroke opening/switch on elevator coordinates with hitting to bend, when elevator is near holdout device, make elevator stop, when if elevator continues to travel because inertia continues motion or other reasons, the lance that stretches out can stop elevator to descend or rise.
As preferably, described hit that bow comprises and the connecting portion of described slip lance captive joint, is connected with described connecting portion to described adapter plate direction extension and between described home switch and described operating switch for the touching section that matches with described home switch and described operating switch.
Connecting portion be used for and elevator on travel switch match, when elevator runs near connecting portion, connecting portion is responded to mutually or touches with the travel switch on elevator, make the elevator reduction of speed and then stop mobile, touching section is used for and home switch and the cooperation of described operating switch, guarantee the normal operation of whole holdout device, guarantee maintainer's personal safety, safe.
As preferably, described connecting portion upper end upwards simultaneously outwards or extend internally, forms the buffer part that tilts.
The setting of the buffer part that tilts, make with when travel switch on elevator matches, process is soft, linear, also improved simultaneously the chance that triggers with travel switch, improved safety, and such structure also makes travel switch when installing, and positional precision does not need too high.
As preferably, described connecting portion lower end simultaneously outwards or extend internally, forms the buffer part that has a down dip downwards.
The buffer part that has a down dip makes with when travel switch on elevator matches, and process is soft, linear, has improved safety, and such structure also makes travel switch when installing, and positional precision does not need too high.
As preferably, the described buffer part that has a down dip becomes 120-150 ° of angle with described connecting portion; The described buffer part that tilts becomes 120-150 ° of angle with described connecting portion.
The slanted angle that buffer part, the buffer part that tilts and described connecting portion become that has a down dip, the selection of angular range is very important, if angle excessive, too small all be unfavorable for elevator on travel switch match.
As preferably, when described touching section triggered described home switch, it is inboard that described slip lance both ends of the surface are positioned at adjacent with it described adapter plate both ends of the surface.
Like this, can make whole holdout device structure compacter, the space that takies when reducing to install, when the slip lance was out-of-run, whole slip lance was positioned at adapter plate, there is no the end side that extends.
As preferably, the cross-sectional plane of described slip lance is rectangle.
Such slip lance can either keep enough structural strengths with less volume, can also not rotate when sliding, and is easy to processing, with low cost, very practical.
As preferably, described laterally steering section comprises left frame, the left frame that is fixed on described adapter plate, and what described slip lance can be free to slide is arranged in described left frame and described left frame.
Adopt left frame, left frame and slip lance to match, one is that cost of manufacture is cheaper, another one, it is the distance that to adjust as required between left frame, left frame, dwindle as much as possible the volume of whole holdout device and take up room, left frame, left frame can weld or be spirally connected and be fixed on adapter plate.
As preferably, the described bow that hits is fixed on described slip lance on the part between described left frame and described left frame.
Like this, the volume of the lance that can reduce to slide simultaneously, also can make and hit the relatively simple for structure of bow.
As preferably, described laterally steering section comprises the steel pipe that is fixed on described adapter plate, and described steel tube surface is provided with groove.
Adopt steel pipe to match as laterally steering section and slip lance, can guarantee that laterally steering section has enough structural strengths, guarantees the safety of whole holdout device.
The utility model beneficial effect is:
Mechanical stopping device of the present utility model adopts slip lance and laterally steering section to coordinate, and forms the structure of drawing and pulling type, makes that whole holdout device volume is little, compact conformation, easy to operate, takes up room in the time of installation little, also has enough safetys.
