Description
Technical field
The present invention relates to a kind of contact net car ladder and grab rail device.
Background technology
Contact net is the main truss of railway electrification project, is the transmission line of electricity of the special shape of powering to electric locomotive of downline overhead erection.Contact net car ladder is the main tool of contact net maintenance ascend operation, and it mainly contains the ladder composition frame part of both sides, and frame roof is provided with footstock and protective guard, and base of frame is provided with the wheel coordinating with rail and walk.
As everyone knows, train running speed is faster, larger by the centrifugal force produced during bend, in order to ensure the safety of train operation, has superelevation design at the outer rail of curve section, and if sweep is 1200m, superelevation of outer rail is 150mm.For the EMUs of running at high speed, suitable superelevation of outer rail can ensure the security of operation of train, but just becomes destabilizing factor for contact net car ladder.In use, on the rail below the terraced contact net being parked in Awaiting Overhaul of contact net car, two workmans are by the terraced footstock climbing to contact net car ladder of contact net car overhauls contact net.Move on rail to prevent contact net Che Tixiang district tilted and contact net car ladder, usually needing to be equipped with several support staff carries out hand steered to contact net car ladder, not only wastes time and energy, inefficiency, but also need to increase extra manpower, add the labour intensity of workman.
Number of patent application 201320725878.2 discloses a kind of card rail fixator preventing operation vehicle for contact wire's ladder from toppling, its structure is simple, easy to operate, the reliable and practical card rail fixator preventing operation vehicle for contact wire's ladder from toppling, this fixator can ensure that in construction car ladder steadily, effectively prevents operation vehicle for contact wire's ladder from toppling, and realizes the object of safe construction.It is the regulating block fixing card two handle tail end welded bands screwed hole at rail, and hand of spiral on two regulating blocks is contrary; Rotating adjusting bolt is full thread structure, screwed hole on the screw thread on its top and two regulating blocks matches, rotate adjusting bolt to pass from another side after being inserted through the regulating block of two handles from a wherein side of body, be provided with annular regulating handle in the wherein one end rotating adjusting bolt.Rotate swivel bolt by annular regulating handle, and change the distance between two regulating blocks under the rotation rotating adjusting bolt, thus regulate it to grip the folding size of end, realize to the fastening of rail with unclamp.
Although it can prevent toppling of contact net car ladder, but there is following deficiency: 1, owing to being change distance between two regulating blocks by the rotation of annular regulating handle, thus realize to the fastening of rail with unclamp, when each parking is fastening and when cycling start is unclamped, workman all needs to rotate the some circles of annular regulating handle, and a contact net car ladder is equipped with four card rail fixators simultaneously, the labour intensity of workman is very large, operate and waste time and energy, extend the operating time, thus decrease the activity duration of workman to contact net, reduce skylight utilization rate (skylight: refer to what route map of train was reserved, contact net power supply unit is carried out to the time of maintenance activity, skylight utilization rate i.e. maintenance efficiency.); 2, complex structure, assembly is more, and fault rate is high, is not easy to maintenance and maintenance; 3, the weight of each card rail fixator is all at more than 20KG, and a contact net car ladder is equipped with four track-catching devices simultaneously, and gross weight, at more than 80KG, is carried very inconvenient; 4, the intensity of product and hardness inadequate, grip end and easily produce distortion, the reliability that it is connected with rail and application life low.
Summary of the invention
The invention provides a kind of contact net car ladder and grab rail device, its structure adds up to rationally, simple operation, can effectively prevent toppling of contact net car ladder, shorten the operating time, significantly reduce the labour intensity of workman, be easy to maintenance and maintenance, reliability is high, alleviates weight, improve portability, solve problems of the prior art.
