Abstract
The utility model relates to a steering angle detection device for a construction machine, and belongs to the technical field of construction machines. The steering angle detection device for the construction machine comprises a steering oil cylinder for driving a steering mechanism, wherein a pull wire connecting end formed at the end of a piston rod of the steering oil cylinder is connected with a pull wire; and the other end of the pull wire is connected to a pull rope sensor capable of detecting the stretching length of the pull wire. The detection device with the structure can detect a steering angle in real time in the process of steering the construction machine by using a hydraulic oil cylinder, so that a driver can timely and accurately adjust a steering device according to the detection value to realize accurate steering.
Description
Technical field
The utility model relates to a kind of
The workerJourney mechanical steering angle detection device belongs to technical field of engineering machinery.
Background technology
Travel when turning in the engineering machinery that adopts hydraulic jack to turn to, the driver reaches the purpose that turns to by the operation steering gear.But in default of the pick-up unit of steering angle, the driver is the just by virtue of experience size of perception steering angle and the variation of steering angle often, the adjusting that turns to again control.So, because part driver experience shortage or experience deviation, in steering procedure, can't accurately hold steering angle by steering gear, make actual steering angle and target rotation angle occur, and then make machine roll the way that correctly travels away from, cause trouble even danger than large deviation.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of variation that can reflect steering angle in real time, for human pilot provides the steering operation reference, thereby is beneficial to promptly and accurately the engineering machinery steering angle pick-up unit of making steering operation.
Include the oil cylinder that turns to that drives steering mechanism in order to solve the problems of the technologies described above engineering machinery steering angle pick-up unit of the present utility model, the backguy link that turns to the piston rod end of oil cylinder to be provided with is connected with a backguy, and the other end of backguy is connected on the rope sensor that can detect the backguy collapsing length.
Winder in the middle of also being provided with one on the described mount pad that turns to oil cylinder, be connected with rope sensor behind the Winder in the middle of described backguy stage casing is walked around, described backguy link is parallel with the flexible direction of steering oil cylinder piston rod with the backguy between the middle Winder again.
Winder is pulley or sleeve in the middle of described.
Adopt the pick-up unit of the utility model setting after such structure can be to turning to the size of angle to detect in real time and calculate in the engineering machinery steering procedure that adopts hydraulic jack to turn to, thereby help the driver according to detected value adjusting steering gear promptly and accurately, realize accurately turning to.
Description of drawings
Fig. 1 is the structural representation of the utility model first embodiment.
Fig. 2 is the structural representation of the utility model second embodiment.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model engineering machinery steering angle pick-up unit is described in further detail.
The utility model as seen from the figure
The workerJourney mechanical steering angle detection device comprises rope sensor 5, turns to oil cylinder 4, backguy link 3, backguy 2 and middle Winder 1.Middle Winder 1 can be pulley (as Fig. 1) or sleeve (as Fig. 2)
The utility model
During work,When the engineering machinery that adopts hydraulic jack to turn to turns to, turn to oil cylinder 4 can produce telescopic variation, and then cause moving of backguy 2, detect elongating or shortening of backguy by rope sensor 5, calculate the size of steering angle by control system according to transducing signal then, offer the driver with for referencial use.The driver can accurately control according to its video data and turn to.Because Winder in the middle of being provided with, backguy in the middle of making between Winder 1 and the backguy link 3 is parallel to the flexible direction of oil cylinder piston bar, thereby the stroke of backguy equates with the stroke of oil cylinder piston bar, need not to carry out complicated conversion, reduced the workload of angle calculation.
