Abstract
The utility model discloses a crawler crane backward-tilting prevention bracket and a crane including the bracket. The bracket includes an upper bracket and a lower bracket, wherein the upper end of the upper bracket upwards supports a backward-tilting prevention oil cylinder; the upper bracket drives the backward-tilting prevention oil cylinder to move left and right; the lower bracket is fixed on a main frame platform of a crawler crane; and left and right relative positions of the upper bracket and the lower bracket are adjustable. Through the adoption of the crawler crane backward-tilting prevention bracket and an up-and-down separated backward-tilting prevention bracket of the crane including the bracket, the backward-tilting prevention upper bracket can be moved when the oil cylinder is required to be moved left and right, so that damage to the backward-tilting prevention bracket caused by left and right movement of the backward-tilting prevention oil cylinder (or a backward-tilting prevention rod) is avoided; and the backward-tilting prevention oil cylinder (or the backward-tilting prevention rod) can be manually adjusted through an operating handle, so that the rod head of the backward-tilting prevention oil cylinder (or the backward-tilting prevention rod) can enter a backward-tilting prevention lead rail smoothly without needing auxiliary equipment, and the labor intensity and cost are reduced.
Description
Technical field
The utility model relates to the anti-hypsokinesis technical field of hoisting crane, relates in particular to the hoisting crane that a kind of crawler crane is prevented the hypsokinesis support and comprised this support.
Background technology
At present, hoisting crane generally all has anti-squat system, to prevent the pulleying of crane amplitude variation mechanism or owing to wind carries and reason such as surface slope causes the safety misadventure of tumbling behind the hoisting crane to take place.
Anti-squat system generally is made up of anti-hypsokinesis oil cylinder (or anti-hypsokinesis bar) and anti-hypsokinesis support; Anti-hypsokinesis support is fixed on the host platform; Anti-hypsokinesis support is used to support anti-hypsokinesis oil cylinder (or anti-hypsokinesis bar); When jib backward luffing be the jib angle when increasing the jib upper rail contact with anti-hypsokinesis, along with the jib angle increases, prevent the disengaging of hypsokinesis and support; When jib forward luffing be jib angle when reducing, anti-hypsokinesis breaks away from guide rail, prevents that the hypsokinesis oil cylinder contacts with anti-hypsokinesis support, bracket leg is propped up anti-hypsokinesis.
There is following shortcoming in existing anti-hypsokinesis support:
1) there are left and right sides position deviation in platform and jib when production or follow-up assembling use; Because existing anti-hypsokinesis support can not left and right adjusting; When jib backward luffing be that the jib angle is when increasing; Anti-hypsokinesis oil cylinder (or anti-hypsokinesis bar) head can exist can not get into the situation of jib guide rail smoothly, thereby causes anti-squat system or jib structure to damage;
