Description

Subway track folding platform device

Technical Field

The utility model relates to the technical field of rail transit, in particular to a subway rail folding platform device.

Background

In the overhaul of a train frame, maintenance personnel need to carry out maintenance operations such as repairing the head lamp, the windshield wiper and the front windshield of a cab on an overhaul track with a maintenance trench, and the maintenance personnel can only stand on a single track for operation during maintenance, and because the contact area between feet and a single steel rail is small, the personnel easily generate gravity center deviation and the risk of falling off the rail surface trench during the forced maintenance technical action;

in order to overcome the inconvenience of movement of maintenance personnel in the working process of the subway train head and the danger of ground leaving operation.

Disclosure of Invention

The utility model aims to provide a subway track folding platform device which is unfolded and installed on a maintenance track with a maintenance trench in the use process, so that the aim of moving and stabilizing operation of personnel in front of a train head is fulfilled.

In order to achieve the above purpose, the present utility model provides the following technical solutions:

the subway rail folding platform device comprises a first pedal and a second pedal, wherein the first pedal and the second pedal are connected through a stainless steel hinge, so that the first pedal and the second pedal can be folded and unfolded; the width of first footboard and second footboard all is greater than the orbital width of maintenance, and the lower surface both ends symmetry of second footboard is equipped with limit stop, and when the footboard was placed on the maintenance track, two limit stop were located two maintenance orbital outsides respectively.

As a further improvement of the scheme, the first pedal and the second pedal are composed of a steel frame at the lower end and a hollowed-out plate surface at the upper end, and the hollowed-out plate surface is fixedly welded on the steel frame.

As a further improvement of the scheme, the two ends of the first pedal are provided with handles, and the two ends of the handles are fixedly connected to the steel frame of the first pedal.

As a further improvement of the scheme, the edges of the upper surfaces of the first pedal and the second pedal are respectively provided with a warning adhesive tape.

Compared with the prior art, the utility model has the beneficial effects that:

1. the utility model has the advantages of portability and portability, and the hollow design of the panel surface greatly reduces the overall weight.

2. The utility model has high stability, and the bottom of the platform is provided with the limiting stop, so that the platform is reliably fixed on the track, and the platform cannot move left and right.

3. The folding type platform has flexibility, the two channel plates are connected together through the hinge, and the folding type platform is convenient to move and saves space.

Detailed Description

The technical scheme of the patent is further described in detail below with reference to the specific embodiments.

1-4, a subway rail folding platform device comprises a first pedal 1 and a second pedal 2, wherein the first pedal 1 and the second pedal 2 are connected through a stainless steel hinge 3, so that the first pedal and the second pedal can be folded and unfolded; the width of first footboard 1 and second footboard 2 all is greater than the orbital width of maintenance, and the lower surface both ends symmetry of second footboard 2 is equipped with limit stop 5, and when the footboard was placed on the maintenance track, two limit stop 5 were located two maintenance orbital outsides respectively, prevented that the footboard from sliding.

Wherein, first footboard 1 and second footboard 2 comprise by the steelframe 7 of lower extreme and the fretwork face 6 of upper end, and fretwork face 6 fixed welding has alleviateed whole weight greatly on steelframe 7, convenient light transport and accomodate in face fretwork design.

Wherein, the both ends of first footboard 1 all are equipped with handle 4, and handle 4's both ends are through fixed connection on the steelframe 7 of first footboard 1, conveniently carry behind folding first footboard 1 and second footboard 2 and get, carry.

Wherein, the upper surface edge department of first footboard 1 and second footboard 2 all is equipped with warning sticky tape, can remind operating personnel platform limit, makes personnel's operation go on in a certain limit.

The working principle of the utility model is as follows: in the use process, the first pedal 1 and the second pedal 2 are unfolded to overlap the overhaul rails, the two limit stops 5 are respectively positioned at the outer sides of the two overhaul rails, the limit stops 5 are fully contacted with the rail surface by pressing the pedals, so that maintenance personnel can be ensured to stand stably and reliably, the personnel can conveniently move left and right, the operation space is greatly increased, and the personal safety of the off-ground operators is ensured; when not in use, the first pedal 1 and the second pedal 2 can be folded and fixed through the binding bands, so that the occupied space during storage is reduced, and the lifting handle can be conveniently and easily carried.
