Abstract
The utility model discloses a fastening device capable of preventing a gantry crane running rail from turning over, which comprises a base fixed with a sleeper through a long nail, wherein the middle part of the upper end surface of the base is provided with a first chute, a bolt used for fixing the running rail is arranged in the first chute, and two sides of the first chute are respectively provided with a second chute; a sliding seat is arranged in the first sliding groove in a penetrating manner through a bolt; two sides of the bottom of the sliding seat are respectively provided with a sliding block for embedding the second sliding chute; and a slope surface attached to the surface of the walking rail is arranged at the middle side of the bottom of the sliding seat. The utility model aims at providing a fix orbital sleeper earlier can clip the both ends about gantry crane walking rail to the fastener of locking walking rail top surface and bottom surface.
Description
Technical Field
The utility model relates to a track construction field especially relates to a fastener that can prevent that gantry crane walking rail from turning on one's side.
Background
At present, in the construction process of a ballastless track engineering, a gantry crane is basically adopted to hoist objects, the gantry crane is important internal circulation equipment for construction in a ballastless track engineering tunnel and is also an important hazard source in the ballastless track engineering construction, and particularly a walking rail arranged below the gantry crane. However, as the travelling rail is too long, the cable grooves are flat and uneven, and the rivet fixation of the gantry crane is limited when the travelling rail travels. The top surface of the walking rail is pressed through the steel plate, the pressing surface is required to be made according to the shape of the walking rail, the rail gauge is not easy to adjust, and the side turning of the walking rail is easy to happen, so that potential safety hazards are caused. Therefore, there is an urgent need for a sleeper that can fix a rail, clamp the left and right ends of a gantry crane running rail, and lock the top and bottom surfaces of the running rail.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome not enough among the above-mentioned prior art, aim at providing an earlier fix orbital sleeper, can clip the gantry crane walking rail about both ends to the fastener of locking walking rail top surface and bottom surface.
In order to achieve the above purpose, the technical scheme of the utility model is realized like this:
a fastening device capable of preventing a gantry crane travelling rail from side turning comprises a base fixed with a sleeper through a long nail, wherein a first sliding groove is formed in the middle of the upper end face of the base, a bolt used for fixing the travelling rail is arranged in the first sliding groove, and second sliding grooves are formed in two sides of the first sliding groove respectively; the bolt in the first sliding chute penetrates through the sliding seat; two sides of the bottom of the sliding seat are respectively provided with a sliding block for embedding the second sliding chute; and a slope surface attached to the surface of the walking rail is arranged at the middle side of the bottom of the sliding seat.
Furthermore, the width of the sliding block is matched with that of the second sliding chute.
Furthermore, the included angle of the slope surface is formed by a right-angle triangular structure.
Furthermore, the sliding block and the sliding seat are formed into an integral structure.
Compared with the prior art, the utility model discloses following beneficial effect has:
1. the utility model discloses easily dismouting, low cost. The sliding seats are movably connected to the base through bolts, so that the walking rails are conveniently disassembled and adjusted, the walking rails are fixed between the opposite sliding seats to be locked, and the walking rails are clamped through inclined slope surfaces of the sliding seats and sliding blocks at the bottoms of the sliding seats, so that the walking rails are prevented from being turned over from the left side and the right side of the base. And the tip of sliding seat all outwards extends the second spout, has further restricted the degree of freedom of walking rail both sides around the base, has guaranteed the stability of portal crane.
2. The inclined slope surface can be suitable for various shapes and sizes of running rails, so that the device is integrally suitable for various running rails.
