Abstract
The utility model provides a safe and reliable wheel excavator, which comprises a framework and a pneumatic control system arranged on the framework. The pneumatic control system comprises an air cylinder, a filter, an air distributor, a balance control valve, a balance cylinder, a brake control valve, a brake cylinder, a backset cylinder, a hand-pull valve and a valve locking cylinder. The cylinder, the filter and the air distributor which are connected end to end via a pipeline are used for supplying air to an air utilization unit, the air distributor is provided with four air connectors, one air connector which is connected with the balance valve via a balance control valve is used for controlling balance of the excavator, one air connector which is connected with the brake cylinder viathe brake control valve is used for controlling shifting of the excavator, the brake control valve and the backset cylinder are simultaneously connected for preventing gear shift in a brake state, and another air connector which is connected with the valve-locking cylinder via the hand-pull valve is used for locking a control bar.
Description
Technical field
The utility model relates to a kind of engineering machinery, particularly a kind of wheel excavator.
Background technology
Excavator has been known, and existing excavator generally possesses excavation and load function, and aspect the control of equipment, excavator generally is provided with oil path control system, air-path control system and circuit control system.Wherein said air-path control system comprises source of the gas, filter, control valve, balance cylinder, brake cylinder, source of the gas is an air compression station, compressed air installs after filtration and filters after control valve is connected with balance cylinder and brake cylinder respectively, and the excavator operating personnel realize the balance and the location of vehicle body by control valve.In the practice, often appearing under the situation that brake not have to discharge, operating personnel carry out the gear shift moving operation, and the behavior makes the power train of excavator be damaged especially easily, therefore are necessary braking and the setting of interlocking of gear bar; On the other hand, survey the terrain, perhaps when operating clearance has the people to enter into below the bucket, avoid guaranteeing personal safety because unexpected touching descends the big arm of bucket suddenly when operating personnel get off in operating clearance.
The utility model content
The purpose of this utility model provides a kind of safe and reliable wheel excavator.
The technical scheme that the utility model adopted is such: a kind of wheel excavator, comprise frame and be located at atmospheric control on the frame, described atmospheric control comprises inflator, strainer, air distributor, balance control valve and balance cylinder, brake control valve and brake cylinder, the backset cylinder, hand valve and locking-valve cylinder, described inflator, strainer and air distributor connect successively by the pipeline head and the tail and are used for to using gas unit air feed, the air duct that air distributor is provided with four gas joints and is interconnected with each gas joint, one of them gas joint is connected the balance that is used to control vehicle body by balance control valve with balance cylinder, one of them gas joint is connected with brake cylinder by brake control valve and is used to control the excavator displacement, described brake control valve is connected with the backset cylinder simultaneously and is used for preventing that at braking state pinning gear bar it from being moved by accident, one of them gas joint is connected with the locking-valve cylinder by hand valve, the piston rod of described locking-valve cylinder is provided with a locking-valve sheet, and described locking-valve sheet is located at and is used to prevent that control lever from being caused industrial accident by the accident touching near the frame of excavator control lever.
By adopting the aforementioned techniques scheme, the beneficial effects of the utility model are: described brake control valve is controlled brake cylinder and backset cylinder simultaneously, when brake locking, the gear bar is also pinned by the backset cylinder like this, prevents from not carry out gear-change operation before brake is unclamped; On the other hand, by hand valve control locking-valve cylinder, prevent that the excavator control lever from moving because of the accident touching and cause industrial accident.
Description of drawings
Fig. 1 is the systematic schematic diagram of embodiment;
The specific embodiment
With reference to figure 1; embodiment discloses a kind of wheel excavator; comprise the frame (not shown) and be located at atmospheric control on the frame; described atmospheric control comprises inflator 1; air filter 2; air distributor 3; balance control valve 4 and balance cylinder 5; brake control valve 6 and brake cylinder 7; backset cylinder 8; hand valve 9 and locking-valve cylinder 10; described inflator 1 is a generalized concept; it comprises air compressor; the compressed air that inflator 1 comes out filters through air filter 2; described air filter 2 comprises liquefaction water (condensate water); contaminant filter 22 and lubricating oil distributing valve 21; the former is used for the condensate water of elimination compressed air; the latter then is used for adding lubrication oil so that the more sliding suitable and difficult gas leakage of each movement parts action to compressed air; described air distributor 3 is " ten " font structure; corresponding four gas joints (as snap joint) on its four angles; described four gas joints are interconnected by the air duct of distributor 3 inboards; one of them gas joint is connected with the gas outlet of air filter 2; a gas joint is connected with balance cylinder 5 by balance control valve 4 and is used to control the balance of vehicle body so that excavate and loading operation; a gas joint is connected with brake cylinder 7 by brake control valve 6 and is used to control the excavator displacement; the gas outlet of described brake control valve 6 is connected with backset cylinder 8 by pipeline simultaneously; described backset cylinder 8 is located near the frame of gear bar; when the piston rod of backset cylinder 8 moves; the gear bar is limited dead and can not moves; thereby prevent that operating personnel's maloperation makes the excavator displacement when braking state; and then the safe and reliable running of protection excavator power train; a gas joint is connected with locking-valve cylinder 10 by hand valve 9; the piston rod of described locking-valve cylinder 10 is provided with a locking-valve sheet, and described locking-valve sheet is located at and is used to prevent that control lever from being caused industrial accident by the accident touching near the frame of excavator control lever.
Claims (1)
