Abstract
The utility model discloses a variable speed control device of a travel motor of a hydraulic excavator. The variable speed control device comprises a control button, a right travel control lever, control cables, an electromagnetic valve, a hydraulic hose, the travel motor, a driver seat and a cab bottom plate. The variable speed control device is characterized in that a hydraulic switch of the electromagnetic valve is controlled by controlling the control button on a handle of the travel control lever, and then the electromagnetic valve is used for controlling the travel motor to change the speed by controlling a hydraulic pipeline. The variable speed control device is mainly characterized in that the variable speed control of the travel motor can be very conveniently carried out by controlling the button with a finger of the right hand when in travel control, thereby having the advantages of low cost, simple structure, safety, reliability, easy operation by a user and the like.
Description
Technical field
The utility model relates to a kind of hydraulic crawler excavator running motor speed-change control device.To in the hydraulic crawler excavator walking operation, can control control button on the right joystick lever and just can be like a cork the running motor of hydraulic crawler excavator be carried out speed Control by the right hand in driver's cabin for the driver.
Background technology
At present, the walking speed-change control device of the hydraulic crawler excavator of producing both at home and abroad mostly is pedal gear change or establishes switch in addition and carry out speed Control on operation panel.The weak point of pedal-shifting device need be vacateed a pin during for speed Control and be stepped on foot rest and could realize speed change, there is this speed change gear to take a foot rest control position again, make and when setting up accessories apparatus, must set up control device in addition, aspect the utilizing of limited driving inner space, seem very unfavorable as other places such as operation panel or inside gadgets; And operation panel is established the shortcoming of the scheme of switch control and is that it can not change must vacates the situation that a hand carries out switch control separately that when walking this speed Control of obviously can not walking flexibly, safety factor also can decrease.
Summary of the invention
The purpose of this utility model is to provide a kind of button of controlling of walking integrated latent dress on the joystick lever head by the operation right lateral to realize device to the running motor speed Control.This programme has solved present hydraulic crawler excavator walking speed-change control device and mostly has been pedal gear change or establishes switch in addition and carry out the problem that speed Control is awkward the driver on operation panel, the driver needn't vacate a pin and step on foot rest or vacate a hand and carry out switch control, as long as the operation right lateral is walked the hydraulic crawler excavator running motor speed-change control device that button just can carry out speed Control to running motor of controlling of integrated latent dress on the joystick lever head.
Technical solution of the present utility model is such, hydraulic crawler excavator running motor speed-change control device comprise control that button, right lateral are walked control stick, controlled cable, electromagnetic valve, hydraulic hose, running motor, driver's chair, driver's cabin base plate.
The cable of controlling that it is characterized in that electromagnetic valve arrives right lateral through the driver's cabin floor below and walks the control stick below, and the control stick by hollow causes right lateral and increases on the joystick lever head again, and right lateral walks that the joystick lever head is integrated to be equipped with the stealthy button of controlling.
Walking variable-speed operating control button integrated being installed on the joystick lever head of can walking, control button is positioned at right lateral and walks the place ahead of joystick lever head and the place ahead of hydraulic crawler excavator, controls cable and walks control stick by the right lateral of hollow and guide to controlling on the button of handle.
The cable of controlling of electromagnetic valve is walked the control stick below through driver's cabin floor below arrival right lateral.
Advantage of the present utility model is to walk at right lateral the button of controlling of integrated latent dress on the joystick lever head, by this being controlled the walking speed Control that this button control can realize hydraulic crawler excavator safely, quickly.Have simple in structure, safe and reliable, but advantages such as user's easy operation.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 is the front view that running motor speed-change control device overall structure of the present utility model is installed.
Fig. 2 is the left view that running motor speed-change control device of the present utility model is pressed Fig. 1.
Among Fig. 1 to Fig. 3: control that button (1), right lateral are walked control stick (2), controlled cable (3), electromagnetic valve (4), hydraulic hose (5), running motor (6), driver's chair (7), driver's cabin base plate (8).
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to Fig. 1～Fig. 2, walk the setting of control stick (2) the place ahead at right lateral and control knob (1), right lateral is walked control stick (2) and is adopted the design of steel pipe hollow type, control cable (3) and walk the driver's cabin base plate (8) that arrives behind the central part of control stick (2) under the driver's chair (7) through right lateral, be connected with electromagnetic valve (4) in driver's cabin base plate (8) below, soly just realized the control on the circuit, electromagnetic valve (4) is by hydraulic hose (5) the realization speed Control that is connected with the control mouth of running motor (6).When the driver needs speed change in the process of walking, in walking, only need to refer to that with the right hand button of controlling that the flicking right lateral is walked on the control stick (2) gets final product.
Claims (3)
1, a kind of hydraulic crawler excavator running motor speed-change control device, comprise control that button, right lateral are walked control stick, controlled cable, electromagnetic valve, hydraulic hose, running motor, driver's chair, driver's cabin base plate, the cable (3) of controlling that it is characterized in that electromagnetic valve (4) is walked control stick (2) below through driver's cabin base plate (8) below arrival right lateral, control stick by hollow causes right lateral and walks on control stick (2) handle head again, and right lateral walks that control stick (2) handle head is integrated to be equipped with the stealthy button (1) of controlling.
2, according to the described hydraulic crawler excavator running motor of claim 1 speed-change control device, the integrated right lateral that is installed in of the variable-speed operating control button (1) that it is characterized in that walking is walked on control stick (2) handle head, control button (1) and be positioned at the place ahead that right lateral is walked control stick (2) handle head, with the place ahead of hydraulic crawler excavator, control cable (3) and walk control stick (2) by the right lateral of hollow and guide to controlling on the button (1) of handle head.
3,, it is characterized in that the cable (3) of controlling of electromagnetic valve (4) is walked control stick (2) below through driver's cabin base plate (8) below arrival right lateral according to the described hydraulic crawler excavator running motor of claim 1 speed-change control device.
