Description
Affiliated technical field
The present invention relates to a kind of rail vehicle checkout equipment, especially a kind of for 4 wheels of rail vehicle, detect a flaw simultaneously do not fall to taking turns ultrasonic test equipment.
Background technology
Rail vehicle wheel is in operation and is subject to for a long time large alterante stress, and its inside may crack, and causes potential safety hazard, to this, should regularly to wheel, carry out UT (Ultrasonic Testing).Recent domestic has been developed a kind of equipment that does not fall to taking turns UT (Ultrasonic Testing), wheel need not be removed, but normally be contained under the state on vehicle and detect a flaw at wheel.The citation form of this defect-detecting equipment is: vehicle is parked on the vehicle rail of special-purpose hanger rail bridge.In trench below track bridge, lay a defectoscope track parallel with vehicle rail.Defectoscope chassis moves on this track, can be parked in successively each wheel below of vehicle.Then, the lifting table of defectoscope departs from rail by wheel jack-up, and turns a wheel, and mechanical arm clings to ultrasonic probe on wheel and detects a flaw.
The basic structure of existing equipment and the method for operation are such: on chassis, be fixed wtih a lifting frame, a lifting table in it can move up and down along the guide rail on lifting frame, two horizontal guide pillars vertical with rail are stretched out at lifting table main body middle part, two of lifting table both sides hook pawl beam and are being set with slidably on guide pillar, after lifting table rises, two hook outside movement of pawl beam while on guide pillar, and the hook pawl hooking on pawl beam just rides on two rail respectively; There is a pair of bracket in the outside that hooks pawl beam at each, the rotary hole of bracket is also sleeved on guide pillar slidably, a roller is equipped with in each bracket upper end, bracket is followed hook pawl beam and is moved, and when hook pawl is taken on rail, the roller on the bracket of both sides also moves to respectively the wheel rim below of two wheels of same axletree, then bracket swings to wheel direction, roller is just by wheel jack-up, and drives vehicle wheel rotation, and at this moment mechanical arm comes to probe on wheel and just can detect a flaw.
From said process, at every turn can only axletree of jack-up during the flaw detection of existing equipment, once can only detect one or two wheel thus, efficiency is lower.Particularly the bogie due to most of rail vehicle is diaxon, and the wheel that existing equipment detects on a bogie just need to move twice, sometimes also must turn to, and operates very loaded down with trivial details.In actual motion, find that this is a major defect, cannot adapt to the fast actual demand of high-speed railway operation rhythm, need to develop the novel device that a kind of high-level efficiency does not fall to taking turns flaw detection.
Summary of the invention
The purpose of this utility model is to provide a kind of new rail vehicle wheel and does not fall to taking turns ultrasonic test equipment, can detect a flaw to four wheels on a bogie simultaneously, reaches the object of raising the efficiency.
For achieving this end, technical solution adopted in the utility model is as follows:
This movable type does not fall to taking turns four-wheel defectoscope, in trench between two vehicle rail, work, described defectoscope is mainly by chassis, fixing lifting frame, moving lifting framework, lifting table, tread probe mechanical arm, wheel rim probe mechanical arm forms, it is characterized in that: along on the transportable chassis of vehicle rail direction, one end is fixed wtih a fixedly lifting frame, this fixedly has the riser guide of vertical direction on lifting frame, the chassis other end is fixed wtih the guide rail base plate of moving lifting framework, guide rail on this guide rail base plate is parallel with vehicle rail, moving lifting framework can move on this guide rail base plate, moving lifting framework also has the riser guide of vertical direction, two lifting tables are contained in respectively in above-mentioned fixedly lifting frame and moving lifting framework, each lifting table can move up and down along the riser guide on framework separately, described defectoscope has four wheel rim probe mechanical arms and four tread probe mechanical arms.
On lifting table, be provided with the adjustment guide rail of vertical direction, on this adjustment guide rail, be slidably matched an adjustment planker is housed.
Adjusting planker both sides respectively has one section of horizontal guide rail vertical with vehicle rail, and on two sections of horizontal guide rails, each slides and is being set with a horizontal guide, and two horizontal guide can be flexible to vehicle rail direction respectively along described horizontal guide rail.
Four wheel rim probe mechanical arms are contained in respectively on two lifting tables, fill two, respectively towards both sides vehicle rail on each lifting table.
Four tread probe mechanical arms are contained in respectively on two lifting tables, and two horizontal guide outer ends of each lifting table respectively fill one, respectively towards both sides vehicle rail.
When this movable type does not fall to taking turns the work of four-wheel defectoscope, vehicle is parked on vehicle rail.The structure of rail vehicle is under compartment to be bogie, on a general bogie, there are two axletrees, each axletree two ends wheel-mounted, the excircle of wheel is called tread, tread contacts with rail surface, and tread inner side also has one to enclose the wheel rim that external diameter is greater than tread external diameter, side contacts in the face that wheel rim outside is connected with tread and rail, play the guiding role, wheel rim medial surface is called wheel rim.
During flaw detection work, chassis moves to below a bogie of vehicle in melt pit, and makes fixedly lifting frame aim at an axletree, and moving lifting framework is positioned at another root axletree below of this bogie; Then use with the similar mode of existing defectoscope and push up wheel, different is that two lifting tables are to rise simultaneously, and the hook pawl beam of lifting table outwards moves, and hooks pawl and rides on rail; The bracket upper end roller of two lifting tables is simultaneously by four wheels on two axletrees together jack-up, and drive vehicle wheel rotation, at this moment four wheel rim probe mechanical arms come to four wheel rim probes on the wheel rim of four wheels respectively, four tread probe mechanical arms come to four tread probes on the tread of four wheels respectively, so just can detect a flaw to four wheels simultaneously.
The beneficial effects of the utility model are: this equipment, by four wheels together jack-up are detected a flaw simultaneously, significantly improves work efficiency, have met the requirement of high-speed railway fast pace operation.
