Abstract
The utility model discloses a two -way elevator safety tongs, including the clamp splice that is in the elevator guide rail both sides respectively, the clamp splice articulates there is pulling mechanism, the lateral surface middle part of clamp splice is equipped with the roller bearing, the clamp splice outside is moving the slider, moves the slider and passes through transverse guide connection top panel and lower panel, the medial surface indent shaping of removing the slider is fluted, and the recess is the low high inclined plane in both sides in middle part, it is fixed with tilt up's the last branch and the lower branch of downward sloping to move the slider lateral surface, the terminal shaping of going up branch and lower branch has the cavity, there is the slide bar cavity bottom through spring coupling. The utility model discloses simple structure, convenient to use can carry out the automatic adjustment to the installation error of clamp splice, and braking efficiency is high, and can realize making progress and braking downwards.
Description
Technical field
This utility model belongs to technical field of mechanical equipment, particularly relates to a kind of Bidirection elevator safety pincers.
Background technology
Current elevator safety gear is typically via arranging wedge so that when elevator needs to brake, by the purpose that the inwardly extruding cage guide that slides reaches to stop elevator.But make the blessing face of wedge and the fully mated needs of cage guide install accurately.In addition only accommodating cage guide so that contact surface is restricted, retardation efficiency is not high.Elevator safety gear as last is only capable of realizing downward braking, and can not prevent elevator upper punch.
Utility model content
For solving the problems referred to above, this utility model provides a kind of Bidirection elevator safety pincers.This utility model simple in construction, easy to use, the alignment error of fixture block can be automatically adjusted, retardation efficiency is high, and can realize braking up and down.
For reaching above-mentioned technique effect, the technical solution of the utility model is:
A kind of Bidirection elevator safety pincers, including the fixture block being respectively at cage guide both sides, described fixture block is hinged with shift mechanism；It is provided with roller bearing in the middle part of the lateral surface of fixture block；For mobile slide block outside fixture block, mobile slide block connects top panel and lower panel by cross slide way；The medial surface indent of mobile slide block forms groove, and groove is the inclined-plane that low both sides, middle part are high；Mobile slide block lateral surface is fixed with acclivitous upper rack posts and downward-sloping lower fulcrum bar；The end of upper rack posts and lower fulcrum bar forms cavity；Cavity bottom is connected to sliding bar by spring.
Further improving, fixture block is connected to brake pad by vertical slot；Vertical slot is fixedly arranged in the middle of ball.
Further improving, described sliding bar end is fixed with the friction hoof increasing friction area.
Further main officer of Tibet enters, and described groove is indent arc.
Further improving, described fixture block is hinged by rotating shaft and shift mechanism.
This utility model simple in construction, easy to use, the alignment error of fixture block can be automatically adjusted, retardation efficiency is high, and can realize braking up and down.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Embodiment 1
Below by way of detailed description of the invention and in conjunction with accompanying drawing, the technical solution of the utility model is illustrated.
As it is shown in figure 1, a kind of Bidirection elevator safety pincers, including the fixture block 2 being respectively at cage guide 1 both sides, described fixture block 2 is hinged with shift mechanism 3；Roller bearing 4 it is provided with in the middle part of the lateral surface of fixture block 2；For mobile slide block 5 outside fixture block 2, mobile slide block 5 connects top panel 6 and lower panel 7 by cross slide way；The medial surface indent of mobile slide block 5 forms groove 8, and groove 8 is the inclined-plane that low both sides, middle part are high；Mobile slide block 5 lateral surface is fixed with acclivitous upper rack posts 9 and downward-sloping lower fulcrum bar 10；The end of upper rack posts 9 and lower fulcrum bar 10 forms cavity 11；It is connected to sliding bar 13 by spring 12 bottom cavity 11.
Fixture block 2 is connected to brake pad 15 by vertical slot 14；Vertical slot 14 is fixedly arranged in the middle of ball 16.
When elevator needs jerk, shift mechanism 3 lift or under push away fixture block 2, fixture block 2 and mobile slide block 5 are extruded mutually by roller bearing 4 so that fixture block 2 internally extrude cage guide 1, and mobile slide block 5 is to external movement, and drive sliding bar 13 extrudes hoistway wall 19.So on the basis of extruding cage guide, add the extruding to hoistway wall 19, improve retardation efficiency.Due to, groove 8 is the inclined-plane that low both sides, middle part are high, therefore can upwards brake, it is prevented that elevator upper punch, it is possible to brake downwards, it is prevented that elevator drops.Groove 8 be preferably shaped to indent arc.
When fixture block 2 internally extrudes cage guide 1, if installing accurate not, there is error, then brake pad 15 is subject to the opposition of cage guide 1, with ball 16 for axle, it is automatically regulated to be and the form of cage guide 1 comprehensive engagement, automatically alignment error is adjusted.
Being formed to increase braking further, sliding bar 13 end is fixed with the friction hoof 17 increasing friction area.
Described fixture block 2 is hinged by rotating shaft 18 and shift mechanism 3.
Above are only a concrete guiding embodiment of the present utility model, but design concept of the present utility model is not limited thereto, all changes utilizing this design that this utility model carries out unsubstantiality, the behavior invading protection domain of the present utility model all should be belonged to.
