Abstract
The utility model relates to a cantilever rigid frame and mobile beam assemblies of a rail-withdrawing working device, and provides a work mechanism which is telescopic and can hoist steel rails from two sides. The mechanism is installed on a railway flat car. In a hoisting work, the mobile beam assemblies on two bearing beams of the cantilever rigid frame respectively move transversely toward left and right together with electric hoists hanging thereon along the bearing beams of the cantilever rigid frame under the drive of an oil cylinder, stretch out of the side beam of the flat car and respectively control the two electric hoists hanging on the suspension beams of the two mobile beam assemblies, so as to make electric hoists move to the top of the suspension beams along with each suspension beam, the moving direction being identical with the stretching direction of the suspension beam. When the steel rail is clamped by a rail tong, the electric hoists at two sides are controlled to hoist the steel rail, move to the end surface of the flat car transversely along each suspension beam and put down the steel rail. When the work is finished, a telescopic oil cylinder is controlled and the stretched out mobile beam assemblies and the electric hoists are withdrawn.
Description
Technical field
The utility model relates to a kind of being arranged on railroad transport flat car, but both sides, the cantilever steel frame that loads and unloads simultaneously, transports the receipts rail equipment of the long and following various specification rail of 25m, trave lling girder form.
Background technology
Works department is the work business such unit of mechanization section particularly, after railway line is carried out to the rail replacement operation, need to the old rail of railway line both sides be reclaimed in enormous quantities.At present, domestic railway interests to be received the equipment of rail be T-shaped loop wheel machine or gantry type single-beam yi word pattern loop wheel machine.
T-shaped loop wheel machine arm is divided into two sections, and a hoist ceiling crane is housed on every section arm, and rail is loaded and unloaded.This equipment can be realized both sides receipts rail, but " for the Double-Track Railway circuit, the railway line line-to-line can not stack goods due to iron rule regulation." for T-shaped loop wheel machine, being subject to its structure influence, hoist ceiling crane can not be crossed B-pillar and be loaded and unloaded, and relayable rail, when entrucking, can only be installed in the both sides of T-shaped loop wheel machine column.When the Double-Track Railway circuit unloads rail, as unloaded the entire vehicle rail in same place, just must carry out at twice.Must, to the station main points, carry out head end operation and turn to during this time.As unloaded the entire vehicle rail in two places, during also must shunt to the station main points.Therefore this equipment is in the loading and unloading steel rails process, consuming time large, work efficiency is low.
Single-beam yi word pattern crane hook can move in whole flatcar cross-sectional plane, can realize the same place handling of car load rail.But because each door frame only has a single-beam lifting assembling structure, a lifting appliance is only arranged, can only realize one-sided rail lifting at every turn.Therefore this equipment in the loading and unloading steel rails process, also exists consuming time large, the problem that work efficiency is low.
Carry out the work efficiency of old rail recovery in order to improve railway department, utilize more fully operation skylight point, cantilever steel frame and trave lling girder that we have designed a kind of receipts rail equipment of utility model form.
Summary of the invention
Receive the equipment requirement of rail for adapting to a large amount of bilaterals of railway interests, but the utility model a kind of scalable both sides are provided, lift the operating mechanism of rail simultaneously, this mechanism is comprised of protract gantry type cantilever steel frame and trave lling girder assembly.The use of this kind of structure, make whole receipts rail device, can be in the situation that be subject to the railway curve Curvature Effect, both sides, the function of simultaneously carrying out the loading and unloading steel rails operation have been realized, improved greatly the work efficiency of receiving rail, operating reliability, safety are all relatively good, simultaneously, do not invade railway clearance when this utility model design has guaranteed the coupling of vehicles operation, guaranteed transportation safety.Therefore this utility model design, be applicable to all railway line constructions.
The utility model solves the technical scheme that its technical matters adopts: the cantilever steel frame profile is the gantry type that protracts, the steelframe top front is straight, and in the steelframe flat segments, two carrier bars are set, on two carrier bars at cantilever steel frame top, two trave lling girders are installed respectively to be formed, each trave lling girder forms can be under the driving of independent oil cylinder, along a carrier bar left side separately, move right, trave lling girder is comprised of mast-up, link span, hanging beam three parts form, mast-up is imitative inverted U structure, top is connected with cantilever steel frame by oil cylinder, and contact with carrier bar by friction plate, slide, bottom is connected with hanging beam by link span, hanging beam is by I-beam section, the tooth bar assembly welding forms, the walking wheel of the I-beam section of hanging beam and tooth bar and hoist ceiling crane and gear engagement, for the hoist ceiling crane be installed on it provides suspension, operation, lifting is supported and track.
Receive the cantilever steel frame of rail equipment and trave lling girder and form and be installed on articulated car, while in both sides, carrying out lifting operation, every two cantilever steel frames are one group simultaneously, and four carrier bars on two steelframes and trave lling girder are formed to called after A, B, C, D successively.The A trave lling girder forms under the promotion of oil cylinder, drives corresponding mast-up, link span, hanging beam, hoist ceiling crane traversing along steelframe carrier bar A left, reaches beyond the left side beam of flatcar.The B trave lling girder forms under the promotion of oil cylinder, drives corresponding mast-up, link span, hanging beam, hoist ceiling crane traversing along steelframe carrier bar B to the right, reaches beyond the right side beam of flatcar.Hoist ceiling crane on difference operation A, two hanging beams of B, the A hoist ceiling crane runs to A hanging beam left end left, and the B hoist ceiling crane runs to B hanging beam right-hand member left, and C, D trave lling girder form operating process and A, the operating process of B trave lling girder composition is identical, wherein with limit on the same group, B, D are with limit on the same group for A-C.Both sides are two hoist ceiling cranes on operational correspondence limit simultaneously, and after the hanger rail clamp is lived rail, hoist ceiling crane is mentioned rail and moved laterally in the flatcar end face along corresponding mobile hanging beam, puts down rail.After fulfiling assignment, the withdrawal process that hoist ceiling crane and trave lling girder form is contrary.But thereby scalable both sides have been reached, lift the purpose of rail simultaneously.
Because forming, can laterally stretch left and right along carrier bar trave lling girder, guaranteeing not invade under the prerequisite of facing line maximum cargo transportation gauge, articulated car loads and unloads working space outward and reaches 425mm, has guaranteed that car load carries out the larger lifting space of having of lifting operation on curve.
The beneficial effects of the utility model are: in a gauge that guarantees not overtake other vehicles, be not subject under the prerequisite of railway curve Curvature Effect, but reached scalable both sides, lift the purpose of rail simultaneously, realized both sides, the function of simultaneously carrying out the loading and unloading steel rails operation.
