Description
Technical field
This utility model relates to a kind of unidirectional limiter of speed, the unidirectional limiter of speed of a kind of elevator.
Background technology
In recent years, elevator accident happens occasionally, and the safety of elevator has caused the attention of more and more people.Elevator speed limit
Device, is one of safety con-trol part in elevator safety protection system.When elevator is in operation, no matter which kind of reason makes car send out
Raw hypervelocity, the danger even fallen, and in the case of every other safety guard is inoperative, then limiter of speed and peace
There is linkage action in full pincers, makes lift car stop.Elevator governor is the safety guard of elevator, its Monitoring and Controlling at any time
The speed of car, when supervelocity situation occurs, i.e., during the certain value of rated speed of lift, signal can be sent in time, then
Produce mechanical action and cut off power supply circuits, make traction machine brake.Current elevator governor, the most unidirectional limiter of speed, braking
Block easily produces misoperation, and is not susceptible to situation about resetting after there is brake block action, thus causes the limiter of speed cannot
Run well, bring bigger potential safety hazard to elevator.
Summary of the invention
The technical problems to be solved in the utility model is to provide brake shoes and is not susceptible to misoperation, easily resets, and improves peace
The unidirectional limiter of speed of the elevator of full property and reliability.
In order to solve above-mentioned technical problem, this utility model takes below scheme:
A kind of unidirectional limiter of speed, including base and installation limiter of speed main body on the base, limiter of speed main body is provided with
Electric switch, is provided with brake shoes and spring in described limiter of speed main body, and this spring one end is arranged on brake shoes, the other end is installed
In limiter of speed main body wall.
Being provided with installation cross bar in described limiter of speed main body, spring one end is arranged in this installation cross bar.
Described installation cross bar is provided with draw-in groove, and spring one end is sleeved in this draw-in groove.
Being provided with mounting blocks on described brake shoes, spring housing is contained on this mounting blocks.
Described mounting blocks is provided with draw-in groove, and spring one end is installed in the draw-in groove of this mounting blocks.
Described spring is right angle setting with installation cross bar.
Described limiter of speed main body upper end is provided with dust cover.
Described dust cover is locked in limiter of speed main body by cross pan head screw.
Described limiter of speed main body is connected with base locking by screw bolt and nut, and is set with spring pad on this bolt
Circle.
This utility model is by arranging spring on brake shoes so that brake shoes is not susceptible to misoperation, and in brake
Brake shoes can be made after block action to be more prone to reset, improve the whole machine balancing of limiter of speed.
Accompanying drawing explanation
Accompanying drawing 1 is this utility model main TV structure schematic diagram；
Accompanying drawing 2 is the right TV structure schematic diagram of accompanying drawing 1.
Detailed description of the invention
For the ease of the understanding of those skilled in the art, the utility model will be further described below in conjunction with the accompanying drawings.
As shown in figure 1 and 2, a kind of unidirectional limiter of speed, including base 1 and the limiter of speed main body being arranged on this base 1
2, limiter of speed main body 2 is provided with electric switch 5, is provided with brake shoes 6 and spring 8 in described limiter of speed main body 2, this spring 8 one end
Be arranged on brake shoes, the other end is arranged on limiter of speed main body wall.
For the ease of install and spring can assemble more firm, be provided with in limiter of speed main body 2 installation cross bar 7, bullet
Spring 8 one end is arranged in this installation cross bar 7.Installing cross bar and be provided with draw-in groove, spring one end is sleeved in this draw-in groove, facilitates spring
Suit, and ensure that spring is difficult to from installing landing cross bar.Being provided with mounting blocks 9 on brake shoes 6, spring 8 is sleeved on this
On mounting blocks 9.Mounting blocks is provided with draw-in groove, and spring one end is installed in the draw-in groove of this mounting blocks.Spring is vertical with installation cross bar
Straight installation.This spring is preferably torsion spring.By the restriction of this spring, it is ensured that brake shoes will not occur misoperation, because spring pair
Brake shoes applies a restraint.
Additionally, limiter of speed main body 2 upper end is provided with dust cover 4.Dust cover 4 is locked at speed limit by cross pan head screw 3
In device main body 2.It is easy for installation and removal, by this dust cover, it is to avoid dust or larger particles drop in limiter of speed main body.
It is " Jiong " that this dust cover is typically a semi-closed structure, i.e. shape of cross section, and two sidewalls are locked in limiter of speed main body, on
The roof of side then covers in limiter of speed main body.
Limiter of speed main body 2 is connected with base locking by bolt 10 and nut, and is set with spring washer on this bolt,
This bolt is preferably hexagon-headed bolt, thus ensures to install the steadiness connected and reliability.
It should be noted that the above is not to restriction of the present utility model, without departing from wound of the present utility model
On the premise of making design, any obvious replacement is all within protection domain of the present utility model.
