Abstract

The utility model relates to an automatic tower boom buffer bar lift-up device for a caterpillar crane, which belongs to the automatic buffer bar lift-up device for the crane. The buffer bar lift-up device comprises a tower type fly jib (1), a main jib (2), a buffer bar (3) and an automatic buffer bar lifter (4); the tower type fly jib is connected at the upper side end of the main jib, a locking groove is arranged on one side of the tower type fly jib, and the buffer bar lifter is connected on the tower type fly jib; the top end of the main jib is connected with one end of the buffer bar, and the other end of the buffer bar is arranged on one side of the tower type fly jib. The automatic buffer bar lift-up device has the advantages of simple structure and reliable work and is easy to operate without external force; the self weight of a heavy hammer is adopted as the power to maintain a bracket to support the buffer bar to move to the correct position during the operation process of the whole machine; the retroversion action of the tower type fly jib is effectively avoided the self weight of the heavy hummer at one end of the bracket is utilized and no additional device is required, thus saving labor force and improving efficiency. .

Description

Crawler crane tower arm shock strut automatic lifting device
Technical field
The utility model relates to a kind of hoisting crane shock strut automatic lifting device, the device of the tower auxiliary shock strut of particularly a kind of crawler crane automatic lifting.
Background technology
When crawler crane is equipped with tower auxiliary, generally use shock strut to prevent tower auxiliary layback, the angle when the tower arm falls arm between tower arm and the principal arm can hinder arm during less than a certain angle.At present external crawler crane uses electronic sensor and hydraulic ram to control the angle of shock strut, mechanism's complexity, cost is higher, the domestic steel cable restriction shock strut angle that then adopts, operating difficulties, efficient is low, control layback weak effect when tower auxiliary wide-angle, and under the arm state that falls, can not move to suitable position automatically, and need artificial dismounting shock strut when falling arm, waste time and energy.
The utility model content
The purpose of this utility model is to provide a kind of: when tower auxiliary wide-angle the control layback effective, under the arm state that falls, can move to suitable position automatically, do not need the crawler crane tower arm shock strut automatic lifting device of artificial dismounting shock strut when falling arm.
The purpose of this utility model is achieved in that this shock strut jacking apparatus comprises tower auxiliary (1), principal arm (2), shock strut (3) and shock strut automatic lifting device (4); Side on the top of principal arm is connected with tower auxiliary, in a side of tower auxiliary locking groove is arranged, and is connected with buffering automatic lifting device on tower auxiliary, connects an end of shock strut on the top on principal arm top, and the other end of shock strut is positioned at a side of tower auxiliary.
Described shock strut automatic lifting device includes carriage and weight, and weight is connected an end of carriage, is equipped with fraising in the interposition of carriage.
Beneficial effect: owing to adopted such scheme, with the deadweight of the weight on the carriage is that power is kept carriage and supported shock strut when the complete machine operation and move to the tram, when shock strut falls near tower auxiliary coxopodite arm with tower auxiliary, carriage is by the automatic jack-up shock strut of action of gravity, make that angle no longer continues to dwindle between shock strut and the tower auxiliary, thereby no longer hinder tower auxiliary motion, realize the safely dropping of tower auxiliary; When tower auxiliary plays arm, because carriage weight self gravitation effect, carriage no longer hinders the braking of shock strut to tower auxiliary, the control layback is effective when tower auxiliary wide-angle, under the arm state that falls, can move to suitable position automatically, do not need artificial dismounting shock strut when falling arm, reached the purpose of this utility model.Advantage: this shock strut jacking apparatus has simple in structure, reliable operation, easy operating, does not need by external force, with the deadweight of weight is that power is kept carriage and supported shock strut when the complete machine operation and move to the tram, actv. has prevented the hypsokinesis action of tower auxiliary, shock strut automatic lifting device has utilized the weight deadweight of carriage one end, do not need additional device, save manpower, improved efficient.

Fig. 4 is the constructional drawing of the utility model shock strut automatic lifting device.
The specific embodiment
This shock strut jacking apparatus comprises tower auxiliary 1, principal arm 2, shock strut 3, shock strut automatic lifting device 4, side on the top of principal arm is connected with tower auxiliary, side at tower auxiliary has locking groove, on tower auxiliary, be connected with buffering automatic lifting device, connect an end of shock strut on the top on principal arm top, the other end of shock strut is positioned at a side of tower auxiliary.
Described shock strut automatic lifting device includes carriage and weight, and weight is connected an end of carriage, is equipped with fraising in the interposition of carriage.
Tower auxiliary 1 is connected on the principal arm 2 by hinge, for preventing that tower auxiliary 1 excessive layback from causing the car load unstability to increase by a shock strut 3 between tower auxiliary 1 and principal arm 2 and supporting tower auxiliary and associate member thereof.Shock strut automatic lifting device 4 is connected on the tower auxiliary 1 by hinge.
The principle of work of this automatic lifting device:
1, when tower auxiliary 1 falls arm, along with reducing gradually of the angle α of tower auxiliary 1 and principal arm 2, the free end of shock strut 3 moves closer to the locking groove of tower auxiliary 1 one sides, if when not having shock strut automatic lifting device 4, along with reducing gradually of α, shock strut 3 will withstand on the locking groove of tower auxiliary 1 one sides fully, and the arm that can't continue to fall is that α continues to reduce; After increasing buffering automatic lifting device 4 these devices, along with the effect by weight own wt on the shock strut automatic lifting device 4 of reducing of α makes buffering automatic lifting device 4 rotate to an angle around self hinge, avoid its free end to withstand on the locking groove of tower auxiliary 1 one sides thereby support shock strut 3.Thereby tower auxiliary 1 and shock strut 3 have been eliminated under the arm state that falls, because of the angle damage that mutual extrusion causes that diminishes.
2, under working condition, when tower auxiliary 1 elevation angle increases gradually, be that its working process is opposite with the arm that falls, along with reducing of angle α, principal arm 3 is cushioned bar automatic lifting device 4 and supports slowly near tower auxiliary 1, when angle is reduced to certain angle, the free end of shock strut 3 contacts with locking groove on the tower auxiliary 1, contact back shock strut automatic lifting device 4 continues rich hinge rotation because of action of gravity, this moment, shock strut 3 broke away from shock strut automatic lifting device 4, when shock strut 3 begins anti-hypsokinesis action when the locking groove slideway moves to terminal point.
