Description
Technical field
The utility model is the pendulous device of the well heater of a kind of seamless railroad rail welding and post weld heat treatment (normalizing) equipment.
Background technology
Gas pressure welding of rail is the main method that is used for rail welding in the construction of China railways gapless track; Post weld heat treatment (normalizing) is to improve welding joint tissue and the requisite important procedure of performance; Their thermal source all comes from well heater, the width of heating zone depends on the amplitude of fluctuation of well heater, the homogeneous heating degree of heating zone depends on the stability of the hunting frequency of well heater, the amplitude of fluctuation and the hunting frequency of well heater suitably cooperate, and can obtain needed temperature field in the heating zone.
At present, gas pressure welding welding and flame normalizing have obtained widespread use because of its cost performance height.But the swing of its well heater is to drive rocking bar swing down by the manually-operated jack back, drives slide bar and well heater linear reciprocating motion; There are the following problems:
(1), the amplitude of fluctuation of each well heater is controlled by the hand moving well heater of operating personnel with the swinging distance of naked eyes range estimation well heater entirely; Each oscillation centre also can only be leaned on operating personnel's eye estimate with the centering situation of weld seam, makes the width of heating zone and center can't keep stable with the relative position of weld seam.
Each hunting frequency depends on the speed of the hand moving well heater of operating personnel, and the size that its speed is also exerted oneself with the swing speed and the change hand of operating personnel's naked eyes range estimation well heater is entirely controlled; Under the normal condition, need estimate size, direction two to three times that the amplitude of oscillation, wobble frequency and change hand exert oneself p.s., the intact or joint of normalizing of complete weldering, its total degree up to 700 times about.Under so high frequency and intensity, operating personnel can not guarantee the stability of amplitude of oscillation wobble frequency, thereby can't guarantee the temperature field that the heating zone is required.
Because amplitude, frequency and the center of swing can't guarantee that all therefore, joint is easy to generate defective, the rail quality of connection can't guarantee, causes disconnected rail accident to take place when serious.
(2), workman's condition of work is abominable, particularly summer construction: when the hand moving well heater of operating personnel and when estimating amplitude of oscillation wobble frequency, about 1 meter of the distance of its face and the same heating zone of hand (temperature is more than 1000 ℃), big to the fire damage of human body skin, the high light of heating zone is also very big to the injury of eyes; Operation posture is the semi-crouch formula, and is very easily tired.
Summary of the invention
The purpose of this utility model is to provide a kind of easy to operate, labour intensity is low, the rail quality of connection the is stable gas pressure welding of rail and the digital control type pendulous device of flame normalizing well heater.
The utility model solves its technical matters, and the technical scheme that is adopted is: the digital control type pendulous device of a kind of gas pressure welding of rail and flame normalizing well heater; Two slide bars that contain on having heaters, head, the head link to each other with well heater, and two slide bars link to each other with a driving mechanism, it is characterized in that: described driving mechanism is numerically controlled driving mechanism.
Consisting of of first kind of mode of above-mentioned numerically controlled driving mechanism:
