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 the high ferro motor train unit carriage of the present invention belongs to the hoisting facilities field, particularly high ferro hoisting crane auxiliary facility.
Background technology
Developing rapidly of high speed railway made huge contribution for the communications and transportation development of China in recent years, greatly shortened haulage time, alleviated the pressure of railway transportation and land transportation and air transport.China Express Railway transportation has entered Rapid development stage, and the raising of the capability of independent innovation is Development of High Speed Railway provides the key point of quick, safe social orientation to its people.In order to guarantee that it moves safely and effectively, the research of the special rescuing equipment high speed railway wrecking crane that matches with it is necessary, and it is being processed train operation accident, is playing upsetting and cover vehicle, eliminate circuitry obstacle, shorten in the high speed railway rescue work of time of interruption of train running and play an important role.
Motor train unit carriage is to be assembled by the multi-disc steel structure, from the present motor train unit steel structure of usefulness, no matter be that plate-girder adds stressed-skin construction or the 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 the distortion repair.Particularly motor train unit leading portion steel structure has not allowed any distortion, particularly asymmetrical deformation.Use traditional suspender to execute and hang, suspender acts directly on the 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 the 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 provides a kind of special hanger for the high ferro motor train unit carriage, can not damage the agent structure whole motor train unit carriage of slinging, and suspension centre is sunk, and effectively increases the lifting altitude of hoisting crane, and the installing/dismounting convenient transportation.
Patented technology scheme of the present invention is as follows:
The present invention is used for the special hanger of high ferro motor train unit carriage, comprises suspension hook, hanging beam, carriage and hoist cable, and characteristics are: cube support body adaptive with the motor train unit carriage casing that carriage is comprised of vertical beam, horizontal curb girder, vertical strut and horizontal joist; Hanging beam is comprised of crossbeam and longeron, the crossbeam center of hanging beam is connected with crane hook by bearing pin, carriage places the motor train unit carriage lower box, its horizontal joist directly holds in the palm the supporting point place in the middle of two bogie trucks of motor train unit carriage bottom half, and the longeron end of hanging beam is connected by flexible hoist cable with carriage support body upper node.
Above-mentioned carriage has four vertical beams to be separately positioned on four jiaos, it is inboard that horizontal curb girder is fixed in respectively each vertical beam, four vertical beam upper ends are connected through bearing pin with two parallel longitudinal direction strut two ends respectively, and these four vertical beam lower ends are connected by bearing pin with two parallel transverse joists respectively.
Described vertical strut divides bar to be flexibly connected through flange by multistage.
Above-mentioned hanging beam is comprised of a crossbeam and two longerons, two longerons are fixedly connected on respectively the upper surface at crossbeam two ends by the lower cover of its lower surface, between hanging beam crossbeam and longeron, form the relative level diff-H, the suspension centre that is arranged on the hanging beam crossbeam is sunk, to have increased the lifting altitude of hoisting crane with respect to longeron.
Innovation advantage of the present invention:
Suspender creativeness of the present invention has adopted the length cube support body carriage support body with the suitable shape of motor train unit carriage, the horizontal joist of carriage is directly held in the palm at the middle supporting point place of two bogie trucks of motor train unit carriage, vertical strut of carriage is peripheral in the compartment along the rail holder, four nodes in carriage support body top connect with the corresponding end of hanging beam longeron by hoist cable, by be arranged on the suspension hook lifting that hanging beam center suspension centre is connected, during lifting operation, carriage only limits the degree of freedom of motor train unit carriage gravity direction, vertical strut between the vertical beam can bear the component of hoist cable horizontal direction, guarantees that motor train unit carriage itself is not subjected to axial force along the rail direction; The component of vertical track direction suspender inside guaranteed that motor train unit carriage itself is not subjected to vertical squeese pressure when the horizontal joist between the vertical beam was born lifting; Simultaneously, horizontal curb girder is welded on vertical beam sidepiece, effectively prevent the rollover of motor train unit carriage in the lifting process, because suspender of the present invention is being executed when hanging, motor train unit steel structure part itself does not stress, therefore, suspender of the present invention can not damage the motor train unit agent structure and the whole motor train unit carriage of slinging, thereby has solved this difficult problem of zero damage lifting motor train unit carriage in the high speed railway rescue work; Two longerons of the design's hanging beam are fixedly connected on respectively the upper surface at crossbeam two ends by the cover plate of its lower surface, the relative height that consists of hanging beam crossbeam and longeron is poor, with respect to longeron, the suspension centre that is arranged on the hanging beam crossbeam is sunk, increased the lifting altitude of hoisting crane.Effectively strengthen the space of the relevant operation of crane hook, solved the problem that the prior art crane hook is perplexed by operation spacing limitation.
In addition, adopt bearing pin to connect between the carrier member of the present invention, its vertical strut divides bar to be flexibly connected by multistage, easy accessibility, and be convenient to transportation.
