Description
Technical field
The present invention relates to home lift technical field, relate to the mechanical stopping device that the maintenance of a kind of home lift uses in particular.
Background technology
Along with the development of urbanization, the market development of home lift is very quick, in order to ensure that home lift is in maintenance, servicing operations, the personal safety of maintainer, for this reason, State General Administration for Quality Supervision and normalisation cuncil have issued GB/T21739-2008 " home lift manufacture and installation specification " in May, 2008, this specification has had clear and definite regulation to the top layer of home lift and pit space, when the life security of repair and maintenance personnel can not be guaranteed in the top layer of home lift and pit space, need installing mechanical stopping device as accessory equipment to ensure this survival space.
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 while be fixed on the L shape connecting panel on cage guide, trough-shaped base is installed with inside the another side of L shape connecting panel, 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 with swing arm, elastic mechanism is arranged on the top of S. A., swing arm upper end is installed with energy disperser, swing arm lower end is wedge shape, swing arm inwall is installed with junction button, junction button is connected with the spanner that declutches of restriction swing arm turned position.This utility model is switched by declutch spanner controller buffer and swing arm simultaneously between normal condition and blocked state, makes it simply easy to operate.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 when installation to take very large space, and in home lift, the height of a lot of floor is not very high, and tunnel dimension is less, does not have space to install.
Summary of the invention
The object of the invention is, for the deficiencies in the prior art part, to provide a kind of mechanical prevention device for domestic elevator, its structure is simple, volume is little, is convenient to install, and the space taken when installation is little, and safety is high.
In order to solve the problems of the technologies described above, technical scheme of the present invention is as follows: a kind of mechanical prevention device for domestic elevator, comprise adapter plate, described adapter plate is provided with home switch, operating switch, laterally steering portion, in described laterally steering portion, slip lance is installed, described slip lance is fixed with and hits bow, described in hit bow a part between described home switch and described operating switch for matching with described home switch and described operating switch.
Mechanical stopping device of the present invention, adopt slip lance, laterally steering portion, by oscillating rod type holdout device in the past, become drawing and pulling type holdout device, whole holdout device volume is significantly reduced, structure is very compact, be convenient to install, dismounting, installation takes up room little, hoistway arbitrary height can be installed on request, 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 close to holdout device, elevator is stopped, if time elevator is due to inertia continuation motion or other reasons continuation traveling, the lance stretched out can stop elevator to decline or rise.
As preferably, described in hit bow comprises and described slip lance is fixedly connected with connecting portion and be connected with described connecting portion and extend to described adapter plate direction and touching portion for matching with described home switch and described operating switch between described home switch and described operating switch.
Connecting portion is used for matching with the travel switch on elevator, when elevator runs to close to connecting portion time, connecting portion and the travel switch on elevator are responded to mutually or are touched, make elevator reduction of speed and then stop mobile, touching portion is then used for coordinating with home switch and described operating switch, ensure the normal work of whole holdout device, ensure the personal safety of maintainer, safety is high.
As preferably, described connecting portion upper end upwards outwards or extend internally, forms surface thereof buffer part simultaneously.
The setting of surface thereof buffer part, make when matching with the travel switch on elevator, process is soft, linear, also improve the chance triggered with travel switch simultaneously, improve safety, and such structure also makes travel switch when installation, and positional precision does not need too high.
As preferably, described connecting portion lower end outwards or extend internally, forms the buffer part that has a down dip downwards simultaneously.
Have a down dip buffer part, makes when matching with the travel switch on elevator, and process is soft, linear, improves safety, and such structure also makes travel switch when installation, and positional precision does not need too high.
As preferably, described in the buffer part that has a down dip become 120-150 ° of angle with described connecting portion; Described surface thereof buffer part becomes 120-150 ° of angle with described connecting portion.
Have a down dip slanted angle formed by buffer part, surface thereof buffer part and described connecting portion, and the selection of angular range is very important, if angle excessive, too small being all unfavorable for matches with the travel switch on elevator.
As preferably, when described touching portion triggers described home switch, described slip lance both ends of the surface are positioned at inside described adapter plate both ends of the surface adjacent with it.
Like this, whole holdout device structure can be made compacter, the space that takies when reducing to install, when slip lance is out-of-run, whole slip lance is positioned at adapter plate, does not have one end to extend side.
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 slip in not rotate, and be easy to processing, with low cost, very practical.
As preferably, described laterally steering portion comprises the left frame, the left frame that are 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.
Left frame, left frame and slip lance is adopted to match, one is that cost of manufacture is cheaper, another one, to adjust the distance between left frame, left frame as required, reduce the volume of whole holdout device as much as possible and take up room, left frame, left frame can weld or be spirally connected and be fixed on adapter plate.
As preferably, described in hit bow and be fixed in the part of described slip lance between described left frame and described left frame.
Like this, the volume of slip lance can be reduced, meanwhile, also can make to hit the relatively simple for structure of bow.
As preferably, described laterally steering portion comprises the steel pipe be fixed on described adapter plate, and described steel tube surface is provided with groove.
Adopt steel pipe to match as laterally steering portion and slip lance, can ensure that laterally steering portion has enough structural strengths, ensure the safety of whole holdout device.
Beneficial effect of the present invention is:
Mechanical stopping device of the present invention, adopts slip lance and laterally steering portion to coordinate, forms the structure of drawing and pulling type, such that whole holdout device volume is little, compact conformation, easy to operate, takes up room little, also have enough safetys when installation.
