Abstract
The utility model relates to a kind of major-minor hook high pedestal jib crane, comprise gate seat machine, machine room platform, Shears and major and minor jib, machine room platform and Shears are all supported on the rotary support post of gate seat machine, described machine room platform is provided with luffing hoisting mechanism, principal arm frame hoisting mechanism and secondary arm frame hoisting mechanism, 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.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.
Description
Technical field
The utility model 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, it is simple that the utility model provides a kind of structure, 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 adopted in the utility model: 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 utility model 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.
