The invention discloses a locking device for an excavation working device of a lateral moving type loader-digger. The locking device comprises the excavation working device and a frame, wherein the root of the excavation working device is installed on the frame through a lateral moving frame; both the lateral moving frame and the excavation working device can move on the frame left and right; a first connection portion is arranged at an excavation end of the excavation working device; a second connection portion is arranged on the frame; and the first connection portion and the second connection portion are connected through a steel wire rope. The locking device has the following benefits: the device has the characteristics of simple structure, high reliability and the like; and the reliability of the locking structure and the safety of the device are greatly improved.
Description
Technical field
The present invention relates to a kind of locking device, particularly a kind of side shifting type loader-digger excacation device locking device.
Background technology
Loader-digger is commonly called as two and hurries, and is a kind of Versatile Construction Machinery equipment simultaneously comprising load terminal equipment and digging end equipment, can be divided into middle-set-type and side shifting type two kinds according to the mechanism form of digging end equipment.The digging end equipment of middle-set-type loader-digger is positioned on the axis of loader-digger, and the structure that can swing is as mini-excavator, and its digging end equipment both sides are provided with frogleg bracing or strutting arrangement; The excavation end face equipment of side shifting type loader-digger comprises a lateral moving frame perpendicular to axis, and whole digging end equipment can move left and right to expand its job area on lateral moving frame, and its bracing or strutting arrangement is positioned at lateral moving frame both sides.
Current side shifting type loader-digger application is more and more, safety problem obtains the mankind equally and payes attention to, but the latch-up structure of existing excacation device cannot lock rocking of being caused by the problem such as pressure release, inertia, load terminal load or sport car process in digging end equipment easily overall around the hinged place with vehicle frame to inner rotary, cause complete machine to rock seriously, and there is potential safety hazard.
Summary of the invention
Goal of the invention: the object of the invention is to provide a kind of safe and reliable side shifting type loader-digger excacation device locking device.
Technical scheme: a kind of side shifting type loader-digger excacation device locking device, comprises excacation device and vehicle frame; Described excacation device root is arranged on vehicle frame by lateral moving frame, described lateral moving frame can move left and right together with excacation device on vehicle frame, the digging end of described excacation device is provided with the first connecting portion, described vehicle frame is provided with the second connecting portion, and described first connecting portion is connected by wire rope with between the second connecting portion.First connecting portion and the second connecting portion are flexibly connected by wire rope when loader-digger carries out loading operation or sport car, the digging end of excacation device head and the tail two ends are all fixed on vehicle frame, avoid digging end rocking when vehicle operation, improve the safety of equipment.
Preference, conveniently install and keep the clean and tidy of vehicle appearance, the digging end of described excacation device comprises rocking arm and dipper, described dipper and rocking arm pass through hinge, described first connecting portion and bearing pin are integral type structure, and the first connecting portion is in end part of pin shaft towards vehicle frame side.
Preference, in order to the locking of digging end can be realized easily and fast, described first connecting portion and the second connecting portion are respectively equipped with U-lag, two U-lags are oppositely arranged, described wire rope two ends are respectively equipped with retainer plate, two described retainer plates lay respectively in U-lag, and described first connecting portion and the second connecting portion are also respectively equipped with the latch assembly running through U-lag, run through retainer plate while described latch assembly runs through U-lag.
Preference, in order to protect locked secure reliable, described latch assembly comprises screw bolt and nut.Latch assembly radially can also arrange the structure of cottor pin at bolt end, or directly adopts cottor pin to be fixed, or several combinations.
Beneficial effect: it is simple that the present invention has structure, and reliability high, substantially increases the reliability of latch-up structure and the safety of equipment.
