Description
Technical field
The present invention relates to the home lift technical field, relate to the mechanical holdout device that a kind of home lift maintenance is used in particular.
Background technology
Along with development of urbanization; The market development of home lift very fast; In order to guarantee home lift in maintenance, in the servicing operations, maintainer's personal safety, for this reason; State General Administration for Quality Supervision and normalisation cuncil have issued GB/T21739-2008 " home lift manufacturing and installation specification " in May, 2008; This standard has had clear and definite regulation to the top layer and the pit space of home lift, when repair and maintenance personnel's life security can not be guaranteed in the top layer and the pit space of household electrical ladder, needs to install mechanical holdout device and guarantee this survival space as accessory equipment.
Number of patent application is CN201120350578.1, the applying date to be that the Chinese utility model patent on September 19th, 2011 discloses a kind of home lift and uses mechanical holdout device; It comprises that one side is fixed on the L shape connecting panel on the cage guide; The another side inboard of L shape connecting panel is installed with the flute profile base, and the set inside of base has the flute profile swing arm in opposite directions of notch and base notches, and is hinged through S. A. between base and the swing arm; Also be connected between base and the swing arm through elastic mechanism; Elastic mechanism is installed in the top of S. A., and the swing arm upper end is installed with energy disperser, and the swing arm lower end is wedge shape; Be installed with junction button on the swing arm inwall, junction button links to each other with the spanner that declutches of restriction swing arm turned position.This utility model is switched between normal condition and blocked state through declutch spanner controller buffer and swing arm simultaneously, makes it easy to operate simple.But it also has weak point, the mechanical holdout device of this utility model, its complex structure; Very difficulty is made, installs all to bulky, poor stability; And, need take very big space in the time of installation, and in the 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.
Summary of the invention
The objective of the invention is the weak point to prior art, provide a kind of home lift to use mechanical holdout device, it is simple in structure, volume is little, is convenient to install, and occupation space is little in the time of installation, and is safe.
In order to solve the problems of the technologies described above; Technical scheme of the present invention is following: a kind of home lift is used mechanical holdout device; Comprise adapter plate, home switch, operating switch, laterally steering portion are installed on the said adapter plate, in the said laterally steering portion slip lance is installed; Be fixed with on the said slip lance and hit bow, a said part of hitting bow is used for matching with said home switch and said operating switch between said home switch and said operating switch.
Mechanical holdout device of the present invention adopts slip lance, laterally steering portion, with oscillating rod type holdout device in the past; Become the drawing and pulling type holdout device, make whole holdout device volume reduce significantly, structure is very compact; Be convenient to install, dismantle, installation takes up room little, can be installed on the hoistway arbitrary height on request; Structural strength is high, safety is good, when in use, should be in working position by the machinery holdout device; Stroke opening/switch on the elevator cooperates with hitting to bend, and when elevator is near holdout device, makes elevator stop; If elevator is because inertia continues motion or other reasons when continuing to go, the lance that stretches out can stop elevator to descend or rise.
As preferably, saidly hit that bow comprises and the connecting portion of said slip lance captive joint, the touching portion that is connected to said adapter plate direction extension and between said home switch and said operating switch, is used for matching with said connecting portion with said home switch and said operating switch.
Connecting portion be used for elevator on travel switch match; When elevator ran near connecting portion, connecting portion was responded to mutually with the travel switch on the elevator or is touched, and made elevator reduction of speed and then stop to move; Touching portion then is used for cooperating with home switch and said operating switch; Guarantee the normal operation of whole holdout device, guarantee maintainer's personal safety, safe.
As preferably, said 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 elevator on travel switch match in, process is soft, linear, has 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, said connecting portion lower ends downward simultaneously outwards or extend internally forms the buffer part that has a down dip.
The buffer part that has a down dip, make with elevator on travel switch match in, process is soft, linear, has improved safety, and such structure also makes travel switch when installing, positional precision does not need too high.
As preferably, the said buffer part that has a down dip becomes 120-150 ° of angle with said connecting portion; The said buffer part that tilts becomes 120-150 ° of angle with said connecting portion.
The slanted angle that the buffer part, the buffer part that tilts of having a down dip become with said connecting portion, 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 said touching portion triggered said home switch, it is inboard that said slip lance both ends of the surface are positioned at adjacent with it said adapter plate both ends of the surface.
Like this, can make whole holdout device structure compact more, occupation space when reducing to install, when the slip lance was out-of-run, whole slip lance was positioned at adapter plate, did not have the end side that extends.
As preferably, the cross-sectional plane of said slip lance is a rectangle.
Such slip lance can either keep enough structural strengths with smaller volume, can also when sliding, not rotate, and is easy to processing, with low cost, and is very practical.
As preferably, said laterally steering portion comprises left frame, the left frame that is fixed on the said adapter plate, and what said slip lance can be free to slide is installed in said left frame and the said left frame.
Adopt left frame, left frame and slip lance to match; One is that cost of manufacture is cheaper; Another one; Be to adjust the distance between left frame, the left frame as required, the volume that dwindles whole holdout device as much as possible with take up room, left frame, left frame can weld or be spirally connected and be fixed on the adapter plate.
As preferably, the said bow that hits is fixed on said slip lance on the part between said left frame and the said 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, said laterally steering portion comprises the steel pipe that is fixed on the said adapter plate, and said steel tube surface is provided with groove.
Adopt steel pipe to match, can guarantee that laterally steering portion has enough structural strengths, guarantees the safety of whole holdout device as laterally steering portion and slip lance.
Beneficial effect of the present invention is:
Mechanical holdout device of the present invention adopts slip lance and laterally steering portion to cooperate, and the structure of formation drawing and pulling type makes little, the compact conformation, easy to operate of whole holdout device volume, and it is little to take up room in the time of installation, also has enough safetys.
