Abstract
The invention provides a special hoisting tool for a high-speed rail motor train unit carriage, and especially relates to a high-speed rail crane supporting facility; the special hoisting tool has a bracket which is a cubic bracket formed by a vertical beam, a horizontal side beam, a vertical strut and a transverse joist, and adapted to a carriage body of a motor train unit carriage; a longitudinal beam end of a hoisting beam is connected with a node at the upper part of the bracket through a flexible sling; the bracket is disposed at the lower part of the motor train unit carriage body; the transverse joist is directly supported at a supporting point between two bogies at the bottom of the motor train unit carriage body; when the hoisting tool of the invention is performing hoisting, the steel structure part itself of the motor train unit is not subject to force, and thus the whole motor train unit carriage can be hoisted without damaging the main structure of the motor train unit; therefore, the problem of nondestructive hoisting of a motor train unit carriage during high-speed rail rescue work is solved; meanwhile, the design of a height difference between the hoisting beam crossbeam and the longitudinal beam allows a hoisting point disposed on the hoisting beam crossbeam to sink, which increases the lifting height of the crane, and solves the problem in the prior art that a lifting hook of the crane is limited by work spacing.
Description
Technical field
A kind of special hanger for high ferro motor train unit carriage of the present invention, belongs to hoisting facilities field, particularly high ferro hoisting crane auxiliary facility.
Background technology
The developing rapidly of high speed railway in recent years, for huge contribution has been made in the communications and transportation development of China, substantially reduces haulage time, alleviates the pressure of railway transportation and land transportation and air transport.China Express Railway transport enters Rapid development stage, the raising of the capability of independent innovation, is that Development of High Speed Railway provides the key point of quick, safe social orientation to its people.In order to ensure that it runs safely and effectively, the research of the special rescuing equipment high speed railway wrecking crane matched with it is necessary, and it covers in the high speed railway rescue work of vehicle, elimination circuitry obstacle, shortening time of interruption of train running play an important role in process train operation accident, a upsetting.
Motor train unit carriage is assembled by pieces of structural steel, from the motor train unit steel structure used at present, no matter be that plate-girder adds stressed-skin construction or die mould beam adds stressed-skin construction, the thin shell structure local stiffness of whole motor train unit carriage is all very low, be very easy to distortion, and be difficult to after distortion repair.Particularly motor train unit leading portion steel structure, has not allowed any distortion, particularly asymmetrical deformation.Use traditional suspender to execute to hang, suspender acts directly on motor train unit carriage, easily makes motor train unit steel structure local pressure and produces distortion.Therefore, researching and developing and a kind ofly can not injure agent structure and the innovation suspender of whole motor train unit carriage of slinging, will be the optimization approach of head it off.
Summary of the invention
The object of the invention is to provide a kind of special hanger for high ferro motor train unit carriage, can not damage agent structure and to sling whole motor train unit carriage, suspension centre can be made again to sink, and effectively increases the lifting altitude of hoisting crane, and installing/dismounting convenient transportation.
Art solutions of the present invention is as follows:
The present invention is used for the special hanger of high ferro motor train unit carriage, and comprise suspension hook, hanging beam, bracket and hoist cable, feature is: bracket be made up of vertical beam, horizontal curb girder, longitudinal strut and horizontal joist with cube support body of motor train unit carriage casing adaptation; Hanging beam is made up of crossbeam and longeron, the crossbeam center of hanging beam is connected with crane hook by bearing pin, bracket is placed in motor train unit carriage lower box, its horizontal joist directly holds in the palm the supporting point place in the middle of motor train unit carriage bottom half two bogie trucks, and the longeron end of hanging beam is connected by flexible hoist cable with bracket support body upper node.
Above-mentioned bracket has four vertical beams to be separately positioned on corner, horizontal curb girder is fixed in inside each vertical beam respectively, four vertical beam upper ends respectively with two parallel longitudinal direction strut two ends through pinned connection, pinned connection is passed through with two parallel transverse joists respectively in these four vertical beam lower ends.
Described longitudinal strut divides bar to be flexibly connected through flange by multistage.
Above-mentioned hanging beam is made up of a crossbeam and two longerons, two longerons are fixedly connected on the upper surface at crossbeam two ends respectively by the lower cover of its lower surface, relative level diff-H is formed between hanging beam crossbeam and longeron, the suspension centre being arranged on hanging beam crossbeam is sunk, to add the lifting altitude of hoisting crane relative to longeron.
Innovation advantage of the present invention:
Suspender creativeness of the present invention have employed the length conformal with motor train unit carriage cube support body bracket support body, the horizontal joist of bracket is directly held in the palm the supporting point place in the middle of motor train unit carriage two bogie trucks, longitudinal strut straight rail holder of bracket is peripheral in compartment, four, bracket support body top node is connected by the corresponding end of hoist cable with hanging beam longeron, by be arranged on the suspension hook that hanging beam center suspension centre is connected and lift by crane, during lifting operation, bracket only limits the degree of freedom of motor train unit carriage gravity direction, longitudinal strut between vertical beam can bear the component of hoist cable horizontal direction, ensure the straight rail direction of motor train unit carriage own not by axial force, the component of suspender inside, vertical track direction when horizontal joist between vertical beam bears lifting, ensures motor train unit carriage itself not by vertical squeese pressure, simultaneously, horizontal curb girder is welded on vertical beam sidepiece, effectively prevent the rollover of motor train unit carriage in lifting process, due to suspender of the present invention execute hang time, motor train unit steel structure part itself does not stress, therefore, suspender of the present invention can not damage motor train unit agent structure and whole motor train unit carriage of slinging, thus solves this difficult problem of zero damage lifting motor train unit carriage in high speed railway rescue work, two longerons of the design's hanging beam are fixedly connected on the upper surface at crossbeam two ends respectively by the cover plate of its lower surface, the relative height forming hanging beam crossbeam and longeron is poor, relative to longeron, the suspension centre being arranged on hanging beam crossbeam is sunk, adds the lifting altitude of hoisting crane.Effectively increase crane hook to be correlated with the space of operation, solve the problem of prior art crane hook by the puzzlement of operational separation distance limitation.
In addition, adopt pinned connection between carrier member of the present invention, its longitudinal strut divides bar to be flexibly connected by multistage, easy accessibility, and is convenient to transport.
