Abstract
The invention discloses a multi-way valve control device of a hydraulic excavator, and the device comprises a pedal, a pedal pin shaft, an installation seat, a turnover sleeve, a sleeve pin shaft, a push-pull rod and a push-pull soft shaft; the pedal is arranged on the pedal pin shaft; the pedal pin shaft and the push-pull rod are connected and are arranged on the installation seat; the sleeve pin shaft is arranged in the turnover sleeve and is connected with the push-pull rod; the push-pull soft shaft is connected with the sleeve pin shaft; a spring is arranged on the installation seat; and the spring and the pedal pin shaft are connected through a locking plate. According to the multi-way valve control device of the hydraulic excavator, the installation seat is arranged on the bottom plate of a driver cab of the hydraulic excavator, the push-pull soft shaft is connected with a multi-way valve, the push-pull soft shaft is pushed by treading on the pedal back and forth, so that a multi-way valve core of the hydraulic excavator is driven, the multi-way valve of the hydraulic excavator is controlled, the hydraulic excavator carries out corresponding action, and the multi-way valve control device of the hydraulic excavator has the advantages that the device can be operated by feet, the use is safe and reliable, the operation is convenient and comfortable, the structure is simple, and the cost is low.
Description
Technical field
The present invention relates to a kind of hydraulic crawler excavator multitandem valve control device, specifically a kind of device of controlling the hydraulic crawler excavator banked direction control valves in the frame for movement mode.
Background technology
At present, the control of hydraulic crawler excavator banked direction control valves is take Hydraulic guide control as main control mode, the shortcoming of Hydraulic guide control mode is that the component accuracy of manufacture of control device requires height, cause use, maintenance cost height, pursuing practical, occasion cheaply, the Hydraulic guide control mode is uneconomic.The main application scenario of small type hydraulic excavator is the farm, the municipal administration maintenance works, use cost to machine is particularly paid close attention to, and mechanical type banked direction control valves control mode is because the control device cost of parts is low, so the most of mechanical type control mode that adopts of the multitandem valve control device on the small type hydraulic excavator.The operator uses the manual operating control device, makes the banked direction control valves valve core movement, makes hydraulic crawler excavator work.When adopting the mechanical type control mode, the hydraulic crawler excavator common function must be by two Handball Association's biconditional operations of operator, therefore when the additional move that needs hydraulic crawler excavator and common function collaborative work, need the operator can control with the limbs except two hands the additional move of hydraulic crawler excavator, pin is comparatively flexible, the quick organ of human body, and the additional move that the operator controls hydraulic crawler excavator by pin is more rational.Therefore, need in design a kind of can be with foot control system, safe and reliable, easy to operate, comfortable multitandem valve control device.
Summary of the invention
The object of the present invention is to provide a kind of hydraulic crawler excavator multitandem valve control device, this control device can be with foot control system, safe and reliable, easy to operate comfortable.
The present invention realizes that the technical scheme that above-mentioned purpose is taked is: a kind of hydraulic crawler excavator multitandem valve control device, comprise foot rest, pedal bearing pin, mount pad, upset sleeve, sleeve bearing pin, pull bar and pushing-pulling flexible shaft, foot rest is installed on the pedal bearing pin, and the pedal bearing pin is connected with pull bar and is installed on the mount pad; The sleeve bearing pin is installed in the upset sleeve and with pull bar and is connected, and pushing-pulling flexible shaft one end is connected with the sleeve bearing pin, and the other end is connected with banked direction control valves; Spring fitting is on mount pad, and lockplate one end is connected with the pedal bearing pin, and the other end is connected with spring.
Described hydraulic crawler excavator multitandem valve control device is installed on the base plate of hydraulic crawler excavator driver's cabin.
Foot rest of the present invention, pedal bearing pin, mount pad, upset sleeve, sleeve bearing pin and pull bar form quadric chain, it is reciprocating that quadric chain promotes pushing-pulling flexible shaft, pushing-pulling flexible shaft drives hydraulic crawler excavator banked direction control valves spool, thereby realizes control hydraulic crawler excavator banked direction control valves.Lockplate is used for the locking foot rest, and quadric chain is in the lock state, and realizes the multitandem valve control device locking, and the effect of spring is to keep lockplate on the position of release or locking.
Advantage of the present invention is: can use the pin operating means, and safe and reliable, be arranged on the hydraulic crawler excavator bottom plate of driving cab, easy to operate, comfortable, simultaneously simple in structure, with low cost.

Fig. 2 is left view of the present invention.
Fig. 3 is operation simulation figure of the present invention.
Fig. 4 is unlocking operation simulation drawing of the present invention.
Reference numeral is: 1. foot rest, 2. pedal bearing pin, 3. lockplate, 4. pull bar, 5. mount pad, 6. spring, 7. sleeve bearing pin, 8. upset sleeve, 9. pushing-pulling flexible shaft.
The specific embodiment
As shown in Figure 1, a kind of hydraulic crawler excavator multitandem valve control device, building block are foot rest 1, pedal bearing pin 2, lockplate 3, pull bar 4, mount pad 5, spring 6, sleeve bearing pin 7, upset sleeve 8 and pushing-pulling flexible shaft 9.Foot rest 1 is installed on the pedal bearing pin 2, and pedal bearing pin 2 is connected with pull bar 4 and is installed on the mount pad 5; Sleeve bearing pin 7 is installed in the upset sleeve 8 and with pull bar 4 and is connected, and pushing-pulling flexible shaft 9 is connected with sleeve bearing pin 7; Lockplate 3 one ends connect pedal bearing pin 2, and the other end is connected with spring 6; Spring 6 is installed on the mount pad 5.
Foot rest 1, pedal bearing pin 2, mount pad 5, upset sleeve 8, sleeve bearing pin 7 and pull bar 4 form quadric chain, and lockplate 3 and spring 6 form locking mechanism.Multitandem valve control device is installed on the hydraulic crawler excavator bottom plate of driving cab by mount pad 5, pushing-pulling flexible shaft 9 connects banked direction control valves, step on foot rest 1 by front and back, as shown in Figure 3, it is reciprocating that the quadric chain that foot rest 1, pedal bearing pin 2, mount pad 5, upset sleeve 8, sleeve bearing pin 7, pull bar 4 are formed promotes pushing-pulling flexible shaft 9, pushing-pulling flexible shaft 9 drives hydraulic crawler excavator banked direction control valves spool, realizes control hydraulic crawler excavator banked direction control valves, makes the hydraulic pressure digging machine make corresponding action.Lockplate 3 can be stirred with pin, as shown in Figure 4, makes foot rest 1 be in the locking/unlocking state, makes quadric chain be in the locking/unlocking state, and under lock-out state, quadric chain can not move, and realizes road control valve device lock function.The effect of locking spring 6 is to keep lockplate 3 on the position of release or locking.
