Description
Technical field
A kind of crane leg is the utility model is related to, more particularly, to a kind of safe and convenient shock-absorbing type crane leg.
Background technology
Crane refers to more action hoisting machineries of vertical-lift within the specific limits and horizontal carrying heavy goods, also known as hangs
Car.Wheel-mounted crane is mainly characterized by：It travels driver's cabin and be combined into one with lifting control cabinl pulpit, (carried out by crawler crane
Band is hung) develop form, the chassis that the crawler belt of walking mechanism and mobile holder part are become to have tire, overcome crawler crane
The shortcomings that (crawler crane) creeper tread road pavement damages, belongs to material carrying machine.The work characteristics that crane gear has is to do
Intermittent exercise, i.e., the corresponding mechanism of the action such as feeding, migration, unloading is alternation in a working cycles, lifting
Machine development commercially and using more and more extensive.Due to often there are some accidents without supporting leg lift heavy and lift heavy traveling,
The speed of traveling is also fast compared with crawler crane (crawler crane)；Operation is stable, lifting capacity is big, can in particular range lift heavy walking,
But it must assure that path formation is solid, tire pressure meets the requirements, hangs ground and must not exceed 50CM；Forbid on-load over long distances
Walking.To ensure job safety, the country, which substantially forbids not making a jack, at present carries out lifting operation.Crane supports the use steel wire
Rope kind includes phosphorized coating steel wire rope, galvanized steel wire rope and bright wire rope.Crane mainly includes lifting mechanism, operation machine
Structure, jib lubbing mechanism, slew gear and metal structure etc..Lifting mechanism is the groundwork mechanism of crane, is by hanging mostly
System and winch composition, also have and lift weight by hydraulic system.Travelling mechanism is to vertical equity migration weight or adjustment
The operating position of crane, usually it is made up of motor, decelerator, brake and wheel.Jib lubbing mechanism is only provided in arm support
On type crane, amplitude reduces when arm support is steeved, and amplitude increases when bending down, two kinds of balance-dividing luffing and non-equilibrium luffing.Revolution
Mechanism is made up of turn round arm support drive device and rotary supporting device.Metal structure is the skeleton of crane, mainly
Bearing part such as crane span structure, arm support and door frame can be box structure or truss structure, or web structure, the available shaped steel conduct having
Backbar.
Current super-tonnage crane is when hanging load, and because supporting leg amount of deflection is big, Vertical Cylinders can be caused with larger wound
Evil.For crane when hanging load, the load got on the bus can transmit the force to ground by supporting leg, leg, pedestal.Prop up in this process
Leg can produce certain amount of deflection and corner, and now the active force suffered by Vertical Cylinders will be at a certain angle with Vertical Cylinders shape,
Excessive angle, the piston rod of oil cylinder can be made to bear larger moment of flexure and the connecting bolt of oil cylinder and supporting leg may be damaged, so as to
Reduce the reliability of supporting leg and the service life of oil cylinder, in some instances it may even be possible to directly damage oil cylinder.Crane leg is auxiliary hoist
One of indispensable infrastructure of operation, the stability of crane leg have a significant impact to the stability of crane, because
This, urgently needs the crane leg that a kind of stability is good.
