Rotating mechanism of a dual-purpose rail flaw detection vehicle

Abstract

The invention discloses a double-purpose rotary mechanism for a rail-defect detector car for a road and a rail. The rotary mechanism comprises a car fixing rotary plate, a positioning rotary bearing is fixed to the middle of the car fixing rotary plate, the lower portion of the positioning rotary bearing is sleeved with an upper connection shaft sleeve, and a lower chain connection rotary shaft is inserted into the positioning rotary bearing; a gear fixing compression nut is arranged on the upper portion of a rotary gear disc, and the gear fixing compression nut is connected with the positioning rotary bearing through threads; the number of rotary driving racks is two, and the two rotary driving racks are arranged on the two sides of the rotary gear disc respectively; linear guide rails are arranged on the lower portions of the outer sides of the rotary driving racks; a cylinder body is arranged on the left side of the car fixing rotary plate; a cylinder rod is connected with a slider fixing plate through a sliding plate connection screw. Work efficiency is improved, and labor intensity is reduced; during equipment replacement, the number of operation workers is reduced, and manual cost is reduced; the mechanism can run on the road and the rail freely and can be assembled on or disassembled from the rail freely, and train running is not affected.

Description

technical field [0001] The invention relates to the technical field of rail flaw detection equipment, in particular to a rotating mechanism of a dual-purpose rail flaw detection vehicle. Background technique [0002] As of 2015, there are 162 manual track detection teams (162) and 4,900 personnel, 98,000 sets of portable flaw detection equipment, and 2,600 sets of manual trolley monorail flaw detection trolleys, with a total cost of 2.6 billion and annual equipment depreciation. And the total wages of employees are 420 million. [0003] The current rail flaw detection equipment has low working efficiency. On average, each flaw detection trolley per person travels 10 kilometers per hour, and the flaw detection efficiency is 40 kilometers per day. Every 20 kilometers of walking, it is necessary to find the nearest water source for the water tank to add water; the technical equipment of the flaw detection equipment is backward, without precise positioning, remote communication...

AI Technical Summary

Problems solved by technology

[0003] The current rail flaw detection equipment is inefficient. On average, each flaw detection trolley per person travels 10 kilometers per hour, and the flaw detection efficiency is 40 kilometers per day.

Every 20 kilometers of walking, it is necessary to find the nearest water source for the water tank to add water; the technical equipment of the flaw detection equipment is backward, without precise positioning, remote communication, data storage can be recalled, and there is no repeatability, etc., resulting in technically impossible secondary confirmation

There are problems with the level flaw detection vehicle, the driving distance is less, the technical configuration is backward, the water source and water coupling effect, can not be off the rail at will, the car is too heavy to manually move the upper and lower rails
