Description

Novel turnout sliding platform

Technical Field

The utility model relates to a sliding platform specifically is a novel switch sliding platform.

Background

After current line switch used a certain age, the material is ageing to be changed, and current change switch method: firstly, assembling a replacement turnout at a specific site, wherein the length of the turnout is about 100 meters, the weight of the turnout is about 200 tons, secondly, transporting the assembled replacement turnout to a construction site by using a traveling rail and traveling wheels, laying the traveling rail on the site, and replacing the turnout. In the process of extracting the longitudinal running rail, because the outlet space is narrow, the whole running rail is heavy, and the extraction stroke is long, a plurality of difficulties and risks exist:

1. when the walking rail is drawn out, the guide rail rubs on the existing turnout or track sleeper, and the sleeper is easy to damage;

2. when turnouts and other trackside equipment exist in the drawing direction, the traveling rail easily collides with a turnout pull rod and a connecting rod, so that the problems of deformation of the pull rod, damage to trackside equipment and the like are caused, and the problems of equipment damage of an industrial and electric combination part such as non-tight contact and non-in-place movement of a switch rail are caused;

3. if the walking rail is provided with the existing turnout along the extraction direction, the walking rail can enter a harmful space of the frog along the turnout, the phenomenon of blocking and difficult pulling-out occur, and the construction progress is influenced;

4. the laying of the guide rail needs a large amount of manual work, is an important reason for limiting the high replacement cost of the turnout, and is easy to generate a key risk point of labor injury;

5. due to the fact that the existing turnout model and the length of the protection rail after the turnout are inconsistent, the longitudinal traveling rail needs to be cut off or lengthened at any time, and therefore assets are wasted;

6. when the walking rail is laid and extracted, a large amount of time of the blocking point is occupied by the flow operation of the blocking point;

7. the connection of the traveling rails needs a large number of steel rails and clamping plates to increase construction machines for overhauling the turnout, and brings a plurality of safety risks to the construction site transfer;

8. the turnout can not adjust the direction at any time when walking on the walking rail, so that the walking and the track shifting can not be carried out simultaneously.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel switch sliding platform to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme:

a novel turnout sliding platform comprises a sliding platform main body, a new replacement turnout, a steel rail, a traveling wheel, a portal track jack and a universal heavy-duty bearing ball; the sliding platform main bodies are symmetrically arranged at the front and the back at equal intervals below the newly replaced turnout, and a plurality of universal heavy-duty bearing balls convenient for the newly replaced turnout to move are arranged on the sliding platform main bodies; a plurality of gate-type track lifting machines are arranged above the new replacement turnout, and a plurality of walking wheels convenient to move are arranged on one side below the new replacement turnout at equal intervals; the running wheels are arranged on the steel rails in a rolling mode.

As a further aspect of the present invention: a plurality of sliding platform cushion layers are fixed at the bottom of the sliding platform main body, and a plurality of sleepers are fixed at the bottom of the steel rail.

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

1. the paired sliding platforms are used for replacing walking rails, the process flow can be seamlessly connected with the operation of excavating a track bed by an excavator, the flow line operation can be realized by only adding one dragging action, the excavation section is advanced by one section, the track bed is excavated, the turnout is synchronously longitudinally moved to the right, and a large amount of time is saved compared with the process of erecting the walking rails;

2. the running rails are not required to be arranged, so that the running rails are not required to be conveyed in place in advance by a rail car, the safety risk of loading, unloading and transportation is avoided, and the cost is saved;

3. the sliding platforms are used without the requirement of track gauge, and only the sliding platforms are parallel to the advancing direction of the turnout, and the distance between the two sliding platforms is not more than the shortest length of the turnout sleeper passing through the sliding platforms;

4. the sliding platform is light in weight, so that the building and the withdrawal are less in labor force and low in labor intensity, and the building and the withdrawal are more convenient;

5. the sliding platform can be manually grouped and withdrawn simultaneously, the withdrawing time is shorter than that of longitudinally dragging the traveling rail by using a rail car, and the existing equipment risks such as line and fork touch caused by dragging the traveling rail can be fundamentally avoided;

6. the accurate longitudinal alignment of the turnout can be realized on the sliding platform, and compared with a method for accurately aligning the longitudinally moved turnout of a walking rail, the method reduces the working procedure of a reverse pad pulley under the sleeper;

7. the condition that a traveling rail is not erected can avoid manual secondary ballast cleaning caused by the fact that a large amount of railway ballasts are brought into the slotting bed when the rail is shifted;

8. the sliding platform is used in the whole process of entering the new turnout and exiting the old turnout, so that the problem of unbalanced loading of the turnout can be avoided.
