Description
Technical Field
The invention relates to the technical field of measuring instruments, in particular to a quick rail inspection trolley capable of automatically passing through a harmful space of a turnout.
Background
In order to ensure that the railway track always keeps in the correct state required by safe transportation, rail inspection trolleys are widely used in engineering to detect the track state. Because the rail inspection trolley relies on the tension force of the spring arranged in the measuring beam to ensure the close contact between the guide wheels at two sides of the rail inspection trolley and the inner acting edge of the steel rail, when the rail inspection trolley enters a common speed turnout section, the guide wheels are trapped in a harmful space of the turnout and cannot retract automatically.
For a rail inspection trolley which is pushed at a walking speed, detection personnel can use manpower to forcedly compress and tension a spring to avoid the running wheel from sinking into the harmful space of the turnout or assist the running wheel to retract when the detection personnel walk to approach the harmful space of the turnout, and even can use manpower to lift the rail inspection trolley to a section with the harmful space of the turnout.
However, for fast rail inspection trolleys that are pushed (pulled) by towing vehicles, the method of passing through the harmful spaces of the switches by means of manual intervention is no longer applicable, forced passing will lead to serious structural damage. At this time, skid type guide wings can be added in front of and behind the guide wheels, but the guide wings required by the method are large in size, and normal measurement of the track gauge widening of the track inspection trolley can be influenced.
Disclosure of Invention
The invention aims to solve the problems that: when the quick rail inspection trolley runs along the steel rail and enters the common speed turnout section, the running wheels can sink into the harmful space of the turnout and cannot retract automatically, and the structural damage of the trolley can be caused under the inertia effect of the quick rail inspection trolley.
The technical scheme provided by the invention for solving the problems is as follows.

Further, the mating surfaces between the first poking pin 7 and the first poking pin hole 9 and between the second poking pin 8 and the second poking pin hole 10 are provided with damping structures in the front-rear direction, so as to reduce the longitudinal impact force on the rail inspection trolley 5 when the traction vehicle 6 starts and brakes. Preferably, the shock absorbing structure is a rubber shock pad or a shock absorbing spring.
Further, the traction vehicle 6 is a self-powered trolley vehicle which can run along a railway track at a speed of 4-20km/h, can be provided with different measuring instruments or measuring modules, can also be used for traction of other rail inspection trolleys, and can be driven by 2-4 persons or not. The traction vehicle 6 adopts wheels with fixed track and rims, which are common to railways, and when the traction vehicle passes through a harmful space section of a common speed turnout, the traction vehicle is limited by a guard rail and cannot excessively sink into the harmful space of the turnout, so that the traction vehicle can maintain a correct transverse running posture and smoothly pass through the harmful space of the turnout.
The beneficial effects of the invention are as follows: compared with the prior art, when the traction vehicle pushes (pulls) the quick rail inspection trolley to enter the ordinary turnout, the trolley can smoothly pass without manual intervention or deceleration, equipment damage and even safety accidents caused by the fact that the travelling wheel falls into a harmful space are avoided, and meanwhile, the system structure is not too complex.
