Abstract
The invention discloses a self-propelled rotary levelling mechanism of a lifting crane of a bridge girder erection machine. The self-propelled rotary levelling mechanism comprises a rack which is provided with a group of winding engines; a sling assembly is hoisted by steel wires of the winding engines, and comprises a movable pulley block; the steel wires pass through the movable pulley block; the movable pulley block is rotatably arranged on a base; drive motors are fixedly arranged on the base; a suspension shaft is rotatably arranged on the base; the upper end of the suspension shaft and the drive motors are in transmission connection with each other, and the lower end of the suspension shaft is hinged onto a beam; the side part of the suspension shaft is connected to one side of the beam through a cylinder; two longitudinal adjusting cylinders are hinged onto the beam; two ends of the beam are provided with holes through which longitudinal girders are installed on the beam; suspension rods are also arranged at two ends of the beam. According to the self-propelled rotary levelling mechanism, the multifunctional requirements on hoisting in one step, automatic rotation and automatic leveling are met, the restriction of regional environments is well overcome, and the requirements of special hoisting and installing methods of a concrete precast segment and a steel box girder are met. The self-propelled rotary levelling mechanism has the advantages of simplicity in operation, low cost, high speed and accuracy in installation.
Description
technical field:
The present invention relates to Bridge Erector field, concrete is that a kind of Bridge Erector hoisting overhead travelling crane is from turning round levelling gear.
background technology:
In order to adapt to the construction needs of China's present stage highway, railway construction, bridge, especially present stage prefabricated joint piece type bridge, assembly type steel bridge construction need, a lot of camp sites are affected by construction condition, geogen, and the prefabricated joint piece of concrete, the transportation of steel case beam are subject to certain limitation (length direction transportation is sometimes vertical with installation in position direction): increase operation lifting number of times and will extend construction period, strengthen construction cost; Some areas cannot enter lifting appliance, and secondary upside-down mounting difficulty is very large.According to multiplex (MUX) ground our customized design of construction experience can meet the hoisting tool special from revolution, self-level(l)ing.
summary of the invention:
The object of this invention is to provide a kind of Bridge Erector hoisting overhead travelling crane from turning round levelling gear, meet specific operation requirement and without by other mechanisms auxiliary set a roof beam in place in place, adopt motor to drive automatic rotary and front and back hydraulic actuating cylinder to adjust angle, accurate positioning is set a roof beam in place, the feature of once setting a roof beam in place and putting in place.
The technical solution used in the present invention is:
Bridge Erector hoisting overhead travelling crane is from turning round levelling gear, comprise frame, it is characterized in that: one group of winch is installed in described frame, on the steel wire of winch, be lifted with lifting assembly, described lifting assembly comprises running block, steel wire is through this running block, running block rotates and is installed on pedestal, on pedestal, be installed with drive motor, be rotatablely equipped with hanging axis, the upper end of the hanging axis drive motor that is in transmission connection, lower end is articulated with on crossbeam, hanging axis sidepiece is connected in a side of crossbeam by cylinder, hinged on crossbeam two longitudinal adjusting cylinders are installed, the two ends of crossbeam are provided with the two ends perforate of longeron and are provided with suspension rod by pull bar.
Described Bridge Erector hoisting overhead travelling crane, from turning round levelling gear, is characterized in that: the described afterbody of two longitudinal adjusting cylinders and the end of piston rod are articulated with on hanging axis, and the end of other piston rod and afterbody are articulated with on the crossbeam of hanging axis both sides.
Compared with prior art, beneficial effect of the present invention is:
The invention solves once lifting, revolution, the multi-functional requirement of leveling voluntarily voluntarily, solve well the impact due to territorial environment restriction, met the prefabricated joint piece of concrete, the special lifting of steel case beam, installation method requirement, and simple to operate, with low cost, speed is fast, installation is accurate.
