Abstract
A related portal crane with main and auxiliary hooks comprises a portal machine, a machine room platform, an A frame, a main boom, an auxiliary boom; the machine room platform and the A frame are both supported by a rotary support column; the machine room platform is provided with an amplitude-variable winching mechanism, a main are rest winching mechanism and an auxiliary boom winching mechanism; and a steel rope of the auxiliary boom winching mechanism is wound around a pulley mechanism at the top of the A frame and is connected with an auxiliary hook at the other end of the auxiliary boom in a pulling way. Under the premise that the height of the A frame of an original portal crane is not changed, the auxiliary boom, the auxiliary boom winching mechanism and an auxiliary amplitude-variable winching mechanism are additionally arranged for regulating the limit angle of an auxiliary arm and realizing hoisting, small-tonnage large-amplitude hoisting is satisfied, utilization efficiency of the equipment is substantially improved, high investment for newly purchasing equipment is avoided, and cost is saved.
Description
Technical field
The present invention relates to a kind of hoisting crane, is a kind of major-minor hook high pedestal jib crane specifically.
Background technology
It is on-the-spot that shipbuilding span winch is mainly used in building berth, floating drydock and tie boat anlongshore dress, carry out the lifting work such as hull splicing, equipment tie boat anlongshore dress, with suspension hook as suspender, the biggest lifting capacity reaches 300 tons, can adapt to big elevating height, significantly with the requirement of small distance operation, along with production-scale continuous expansion, existing span winch cannot meet the large distance lifting of little tonnage.
Summary of the invention
The deficiency of the large distance lifting of little tonnage cannot be met for span winch of the prior art, the invention provides a kind of structure simple, make, easy to use, cost is low, the major-minor hook high pedestal jib crane of large and small tonnage and large and small distance lifting requirements can be taken into account.
The technical solution used in the present invention: a kind of major-minor hook high pedestal jib crane, comprise gate seat machine, machine room platform, Shears and master, secondary arm frame, machine room platform and Shears are all supported on the rotary support post of gate seat machine, it is characterized in that: described machine room platform is provided with luffing hoisting mechanism, principal arm frame hoisting mechanism and secondary arm frame hoisting mechanism, described machine room platform is movably hinged principal arm frame one end, the principal arm frame other end is movably hinged secondary arm frame one end, luffing hoisting mechanism is main transformer width hoisting mechanism, the pulley mechanism that the steel rope of main transformer width hoisting mechanism walks around Shears top sockets the principal arm frame other end, or luffing hoisting mechanism is secondary luffing hoisting mechanism, the pulley mechanism that the steel rope of secondary luffing hoisting mechanism walks around Shears top sockets the secondary arm frame other end, or luffing hoisting mechanism comprises main transformer width hoisting mechanism and secondary luffing hoisting mechanism, the pulley mechanism that the steel rope of main transformer width hoisting mechanism walks around Shears top sockets the principal arm frame other end, the pulley mechanism that the steel rope of secondary luffing hoisting mechanism walks around Shears top sockets the secondary arm frame other end, the pulley mechanism that described principal arm frame hoisting mechanism steel rope walks around Shears top sockets the main suspension hook of the principal arm frame other end, and the pulley mechanism that described secondary arm frame hoisting mechanism steel rope walks around Shears top sockets the secondary suspension hook of the secondary arm frame other end.
The top of described Shears sockets on machine room platform through pull bar, is connected with Z-type pull bar between pull bar and Shears.
The present invention is when former span winch Shears height is constant, set up secondary arm frame, secondary arm frame hoisting mechanism and secondary luffing hoisting mechanism to secondary arm extreme angles adjustment and lifting, meet little tonnage significantly to lift, substantially increase the utilization ratio of equipment, exempt the large input newly purchasing equipment, the cost of saving.
