Abstract
The utility model provides a load-sensitive control device of a milling machine, which comprises a traveling controller, a hydraulic traveling device and an engine, wherein a handle is arranged on the controller; a traveling plunger pump is arranged on the hydraulic traveling device; the engine comprises a traveling motor and a working device; the handle of the controller is connected with the traveling plunger pump; and the traveling motor is connected with the hydraulic traveling device. The load-sensitive control device has the benefits as follows: as the technical scheme is adopted, a diesel engine on the milling machine can roughly keep the rotating speed unchanged under any load condition, and the milling machine is enabled to work stably in case of violent change of load; the torque moment of the working device is ensured; the operation is more convenient; and moreover, the load-sensitive control device has the advantages of simple structure, high safety, high production efficiency and the like.
Description
Technical field
The utility model belongs to the engineering mechanical device technical field, especially relates to a kind of load-sensitive control device of milling machine.
Background technology
In existing technology, milling machine is as a kind of powerful engineering machinery, and load variations is very large.Milling machine is unstable working condition in the situation of load acute variation.When the equipment of milling machine is in a relative consistent state with the power of running motor, the milling machine stable working state.When the diesel powered of running motor because of the variation of load when out of control, the moment of torsion of equipment just can not guarantee.Need research and develop a kind of load sensitive control system that disposes for the economy that improves milling machine according to the problems referred to above.
Summary of the invention
Problem to be solved in the utility model provides a kind of load-sensitive control device of milling machine, especially is fit to the load control of powerful milling machine.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of load-sensitive control device of milling machine, comprise controller, hydraulic walking device and motor, and described controller is provided with one handle; Described hydraulic walking device is provided with a walking plunger displacement pump; Described motor also comprises running motor and equipment, and the handle of described controller is connected with the traveling pump of described motor, and described running motor is connected with described hydraulic walking device; The walking plunger displacement pump of described hydraulic walking device is connected with described controller.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, make under diesel oil function what load state in office on the milling machine to keep rotating speed substantially constant, guarantee that milling machine also can steady operation in the situation of load acute variation; Guarantee the moment of torsion of equipment; More convenient to operate; Have simple in structure, safe, the production efficiency advantages of higher.

4, hydraulic walking device 5, walking plunger displacement pump 6, running motor
7, equipment
The specific embodiment
As shown in Figure 1, the load-sensitive control device of a kind of milling machine of the utility model comprises controller 1, hydraulic walking device 4 and motor 3, and described controller 1 is provided with one handle 2; Described hydraulic walking device 4 is provided with a walking plunger displacement pump 5; Described motor 3 also comprises running motor 6 and equipment 7, and the handle 2 of described controller 1 is connected with the running motor 6 of described motor 3, and described running motor 6 is connected with described hydraulic walking device 4; The walking plunger displacement pump 5 of described hydraulic walking device 4 is connected with described controller 1.
The course of work of this example: motor 3 power of milling machine are distributed in running motor 6 and equipment 7.The handle 2 of load-sensitive control device is in the process of milling machine work, constantly detect the rotating speed of motor 3, when the rotating speed that detects motor 3 drops to the numerical value of controller setting, just feed back to load control device and adjust the swash plate angle of the walking plunger displacement pump 5 of hydraulic walking device 4, thereby reduce the speed of travel of milling machine running motor 6, reduce load, that motor 3 is got back to rated speed, thereby make milling machine in the process of work, automatically control the speed of travel according to the variation of load, guarantee that milling machine also can steady operation in the situation of load acute variation.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
