Description
Technical field
It the utility model is related to the technical field of safety devices of truss bridge detecting vehicle, more particularly to truss two-revolution machine
Structure exceedes a kind of bridge inspection vehicle novel rotation angle limit mechanism during predetermined angular.
Background technology
Bridge inspection vehicle can be that bridge machinery personnel provide job platform in detection process, according to Special working device
Difference, bridge inspection vehicle is broadly divided into two kinds of basket-hanging and truss-like, and truss bridge detecting vehicle is flat using channel-type work
Platform, stability is good, large carrying capacity, and testing staff easily can enter platform from bridge floor or return to bridge floor during use.
At present, truss bridge detecting vehicle job state is a kind of job platform of cantilever beam structure, and platform is returning
Also need to allow to stretch in certain safe range while turning, vehicle deviation of gravity center can be caused by stretching out during beyond safe range
Slide-out is caused too much, is to gather pivoting angle data with encoder mostly in the market, after processor is analyzed
The stretching angle of workbench is controlled, the method cost is high and programme-control easily goes wrong, and safety coefficient is low.
The content of the invention
The purpose of this utility model is to provide a kind of bridge inspection vehicle novel rotation angle limit mechanism, can effectively control
Anglec of rotation when bridge inspection vehicle two-revolution mechanism turns round controls the stretching of truss, the vehicle safety of raising within the specific limits
Property, save overall cost.
Technical scheme is used by the utility model solves its technical problem：A kind of bridge inspection vehicle novel rotation angle
Position-limit mechanism, including rotation balladeur train, travel switch, unloading electromagnetic valve, stroke slider；The rotation balladeur train is slided provided with stroke
Block；The rotation balladeur train both sides are equipped with travel switch；The travel switch side relative with rotation balladeur train is provided with contact；Institute
Travel switch is stated to electrically connect with unloading electromagnetic valve.
Further, the stroke slider is in circular arc, and circular arc to central angle be 60 °.
Further, the automatic hydraulic system of the sufficient arm support action of the external control of the unloading electromagnetic valve.
Further, the unloading electromagnetic valve is 2.
The beneficial effects of the utility model are：The device can effectively control bridge inspection vehicle two-revolution mechanism turn round when
The anglec of rotation controls the stretching of truss within the specific limits, the vehicle security of raising, saves overall cost.
Brief description of the drawings
Fig. 1 is a kind of schematic diagram of bridge inspection vehicle novel rotation angle limit mechanism of the utility model.
In figure：1st, balladeur train is rotated, 2, travel switch, 3, unloading electromagnetic valve, 4, stroke slider, 5, contact.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the embodiment of the utility model is carried out
Clearly and completely describing, it is clear that described embodiment is only part of the embodiment of the present utility model, rather than all
Embodiment, based on the embodiment in the utility model, those of ordinary skill in the art are not making creative work premise
Lower obtained every other embodiment, belong to the scope of the utility model protection.
Embodiment 1
A kind of bridge inspection vehicle novel rotation angle limit mechanism, including rotation balladeur train（1）, travel switch（2）, electromagnetism unloads
Lotus valve（3）, stroke slider（4）；The rotation balladeur train（1）It is provided with stroke slider（4）；The rotation balladeur train（1）Both sides are all provided with
There is travel switch（2）；The travel switch（2）With rotating balladeur train（1）Relative side is provided with contact（5）；The travel switch
（2）And unloading electromagnetic valve（3）Electrical connection.
Further, the stroke slider（4）In circular arc, and circular arc to central angle be 60 °.
Further, the unloading electromagnetic valve（3）The automatic hydraulic system of the external sufficient arm support action of control.
Further, the unloading electromagnetic valve（3）For 2.
Embodiment 2
Travel switch（2）Contact（5）With rotating balladeur train（1）On stroke slider（4）After contact, travel switch（2）Will
Electric signal passes to unloading electromagnetic valve（3）, unloading electromagnetic valve（3）Open automatic hydraulic system automatic deloading.
When it is implemented, rotation balladeur train（1）It is installed on the vertical trusses of bridge inspection vehicle, the workbench on vertical trusses
It can be stretched in security standpoint, when vertical trusses rotation exceedes security standpoint, the workbench on vertical trusses should be kept away
Exempt to stretch out, rotate balladeur train（1）When rotating to security standpoint maximum magnitude, the travel switch on left side or right side（2）Contact（5）
Can be with rotating balladeur train（1）On stroke slider（4）Contact, now, travel switch（2）Electric signal can be passed to unloading electromagnetic valve
（3）, unloading electromagnetic valve（3）The automatic hydraulic system automatic deloading of the sufficient arm support action of external control is controlled, avoids vehicle center of gravity
It is dangerous that deviation causes slide-out to obtain too much.
The utility model can effectively control the anglec of rotation during revolution of bridge inspection vehicle two-revolution mechanism in certain limit
The stretching of interior control truss, the vehicle security and the overall cost of saving of raising.
Although the utility model is described in detail with reference to the foregoing embodiments, come for those skilled in the art
Say, it can still be modified to the technical scheme described in foregoing embodiments, or which part technical characteristic is entered
Row equivalent substitution, all within the spirit and principles of the utility model, any modification, equivalent substitution and improvements made etc., all should
Within the scope of protection of the utility model.
