Abstract
The utility model discloses a running rail anti-shifting device, which comprises a rail, wherein two sides of the rail are provided with baffles, one side of each baffle is provided with a pressure spring, the pressure springs are connected with a hydraulic cylinder, the expansion and contraction of the pressure springs are adjusted through the hydraulic cylinder, so that the extrusion force between the rail and the rail is adjusted, and the end part of the hydraulic cylinder is provided with a backstop used for blocking the hydraulic cylinder; the hydraulic cylinders and the pressure springs are added on the two sides of the track, so that the hydraulic cylinders and the pressure springs form pretightening force, and the problem that the track does not move any more when expanding with heat and contracting with cold is effectively solved; meanwhile, the problems of track joint weld cracking and track deformation are solved; the service life of the large wheel is guaranteed.
Description
Technical Field
The utility model belongs to the technical field of the driving rail, concretely relates to running rail anti-channeling device.
Background
At present, a track is laid on a steel crane beam, the bottom surface of the track is tightly attached to the top surface of the steel crane beam, and a base plate is added at a gap for solid padding. After the rail is adjusted, fixing the rail by adopting a pressing plate, fastening a rail pressing plate bolt, adjusting and fixing the rail, and reserving expansion joints at two ends of the rail; the track pressing plate is used for daily spot inspection, and is timely fastened when being loosened. The clamp plate bolt is loosened frequently, and is fastened once a week on average, so that the influence on production is large.
Furthermore, the rails often exhibit weld cracking or distortion, especially during season changes. When the ambient temperature rises, the rails are pressed against each other, resulting in severe deformation of the rails. When the ambient temperature drops, the rail shrinks, causing the rail joint weld to stretch apart. The rail joint is frequently broken, so that impact is caused to the big driving wheel, and the service life of the big driving wheel is seriously influenced.
The joint welding line of the rail is cracked or deformed to cause the derailment accident of a large wheel of the traveling crane, the whole traveling crane can fall seriously, and potential safety hazards exist;
the adjustment of the track and the thermite welding have high labor intensity and long time consumption.
Therefore, a lane rail anti-play device is required.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a device is prevented drunkenness by moving of moving track.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a device is prevented drunkenness by moving track rail, includes the track, the both sides of track rail are equipped with the baffle, and one side of baffle is equipped with pressure spring, and pressure spring is connected with the pneumatic cylinder, through pneumatic cylinder adjustment pressure spring's flexible to adjust the extrusion force between track rail and the track, the tip of pneumatic cylinder is equipped with the backstop, is used for blocking the pneumatic cylinder.
Specifically, the side surface of the track is provided with a pressing plate for fixing the track.
The utility model discloses following beneficial effect has: the hydraulic cylinders and the pressure springs are added on the two sides of the track, so that the hydraulic cylinders and the pressure springs form pretightening force, and the problem that the track does not move any more when expanding with heat and contracting with cold is effectively solved; meanwhile, the problems of track joint weld cracking and track deformation are solved; the service life of the large wheel is guaranteed.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In the figure: 1-track; 2-a baffle plate; 3-a pressure spring; 4-a hydraulic cylinder; 5-stopping; 6-pressing plate.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings.
As shown in fig. 1, the device for preventing the running rail from moving comprises a rail 1, wherein two sides of the rail 1 are provided with baffle plates 2, one side of each baffle plate 2 is provided with a pressure spring 3, the pressure spring 3 is connected with a hydraulic cylinder 4, the expansion and contraction of the pressure spring 3 are adjusted through the hydraulic cylinder 4, so that the extrusion force between the rail 1 and the rail 1 is adjusted, and the end part of the hydraulic cylinder 4 is provided with a stopper 5 for stopping the hydraulic cylinder 4; the side of the track 1 is provided with a pressing plate 6 for fixing the track 1.
The utility model discloses a pneumatic cylinder 4 adjusts pressure spring 3's pretightning force to adjust the gap of rail junction, when summer, pneumatic cylinder 4 contracts, reduces pressure spring 3's pretightning force, and when winter, pneumatic cylinder 4 stretches out, increases pressure spring 3's pretightning force, thereby the junction between chucking rail 1 prevents rail 1 drunkenness.
The utility model discloses not be limited to above-mentioned embodiment, anybody should learn the structural change who makes under the teaching of the utility model, all with the utility model discloses have the same or close technical scheme, all fall into the utility model discloses an within the protection scope.
The technology, shape and construction parts which are not described in detail in the present invention are all known technology.
