Description

Plate turnover machine

Technical Field

The utility model discloses a plate turnover machine, and relates to the technical field of production of high-speed railway track plates.

Background

The ballastless track slab is widely applied to high-speed railways in the world due to high smoothness, high stability and less maintenance. However, most of the prefabricated track slabs are made of high-grade concrete, the drying shrinkage of the prefabricated track slabs is serious, the heat release amount is also large, and once the prefabricated track slabs are maintained improperly, serious initial defects are likely to occur. In order to improve the prefabrication quality, in the industry, generally, after concrete has certain strength, the track slab is immersed in a water curing pool for curing, so that the track slab is relieved from drying shrinkage, and the temperature of the track slab is reduced. However, when the rail plate is placed in the water culture pond, if the rail plate is horizontally placed, the rail plate cannot be lifted out, so that the rail plate needs to be vertically placed, and two lifting points on the side face are exposed out of the water surface, so that the space can be saved, and the rail plate can be conveniently lifted out of the water culture pond. The whole manufacturing process of the track slab needs to be horizontally placed, the track slab needs to be erected firstly before being placed into a water culture pond, the track slab is placed on a skid and directly turned up by a travelling crane in the traditional method, one side of the track slab can be supported on the skid in the process, the track slab is extremely easy to break, the travelling crane needs to be obliquely pulled and hung during turning over, and the safety is low.

In actual production, after demolding of the track plate is completed, anchor sealing operation is needed, a workshop site is provided with a conveying line, anchor sealing can be completed on the conveying line, and the track plate can be conveyed to the position near the water culture pond. And the overturning of the track slab before the track slab is placed in the water culture pond needs to firstly lift the track slab from the conveying line to the skid and overturn according to the traditional mode, and the overturning mode is not only easy to knock the track slab but also dangerous, and cannot be applied to the continuous production of the track slab and increase the floor area of the track slab production line.

In view of the above, the prior art is obviously inconvenient and disadvantageous in practical use, and needs to be improved.

The base, the rotating arm and the overturning oil cylinder in the overturning mechanism are connected together through the hinge and the bearing assembly, so that the overturning oil cylinder has a very small stroke, the track plate is overturned by 80 degrees, the equipment size is small, and the occupied space is small.

3. If the track slab is directly overturned on the supporting wheel set of the sealing anchor conveying line, the supporting wheel set can be subjected to a large horizontal force in the overturning process, and the service life of the supporting wheel set is greatly shortened. The track plate is jacked up through the lifting mechanism and is separated from the supporting wheel set, so that the track plate is completely positioned on the plate turnover machine and then is turned over, the supporting wheel set is not damaged, the failure rate is reduced, and the problem that the supporting wheel set needs to be replaced periodically is solved;

in addition, the lifting mechanism jacks up the track plate to a position completely separated from the supporting wheel set of the anchor sealing conveying line and then turns over the track plate, so that the guide wheels are not arranged on two sides of the anchor sealing conveying line, the track plate is guaranteed not to deviate during conveying, and the track plate has the deviation problem during conveying.

4. Inside with elevating system's lift cylinder embedding swinging boom, abundant utilization the space, the integrated level is higher to make the panel turnover machine can realize compound motion, the swinging boom can overturn and the jacking again.

5. The two surfaces of the track slab are respectively a track bearing table surface and a bottom surface, the track bearing table surface is an actual use surface, and the requirement on surface quality is high, so that the track bearing table surface faces upwards when the sealing anchor conveying line conveys in order to avoid collision in the conveying process and facilitate observation of the track bearing table surface. And the bottom surface of track board then has a lot of stones, it is very coarse, like this when the upset, if there is not the gyro wheel, that the swinging boom can not swing the epaxial bearing side contact of swinging boom under less angle, only when arriving great angle, the track board just can the landing, with the contact of bearing side, but just there has very big impact this moment, lead to the track board to be knocked open, and the panel turnover machine probably causes the component impaired because of being strikeed, and the gyro wheel through elevating system, change sliding friction to rolling friction, just can make the swinging boom when very little angle, the track board just landing, with the contact of bearing side, almost not strike the production, avoided the track board because of colliding with the scrap that causes, the life of panel turnover machine has been prolonged.
