Abstract
The invention relates to a track fixing device, and particularly relates to a track fixing device for a concrete crane beam or a ground track. The track fixing device provided by the invention consists of a base, a pressing plate, a bolt and a nut. The track fixing device is characterized in that two sides of the base are respectively provided with a blocking groove so as to fix the head part of the bolt; the bolt passes through a bolt hole of the pressing plate and is fixed by the nut; two sides of the base are also respectively provided with a boss; the middle parts of the bosses are provided with threaded holes; the threaded holes are internally provided with screws.
Description
Technical field
The present invention relates to a kind of device for fixing running tracks, particularly the device for fixing running tracks of a kind of concrete crane beam or ground rail.
Background technology
On concrete crane beam or ground rail, fix rail, generally adopt cement concrete pressing plate or use welded rail anchor fitting.In the time using welded rail anchor fitting, must lay steel plate welded rails anchor fitting again at concrete crane beam or ground, this way is installed cumbersome, and installation period is longer.Patent of invention " crane rail fixing device " (ZL02112783.2) discloses a kind of device for fixing running tracks, and this anchor fitting uses exactly in the time of cement concrete or ground rail, must lay steel plate at concrete crane beam or ground.
Summary of the invention
The object of this invention is to provide need to be at the device for fixing running tracks of concrete crane beam or ground laying steel plate.
The present invention is design like this, device for fixing running tracks is made up of base, pressing plate cover plate, screw bolt and nut, be characterized in: there is respectively a retaining groove both sides of base with bolt of rear end plate head, bolt is fixed by nut by the bolt hole of pressing plate, also there is respectively a boss both sides at base, there is tapped bore at middle part at boss, mounting screw in tapped bore.
The present invention is simple in structure, novel, is arranged on and on concrete crane beam or ground rail, does not need to lay steel plate.
Brief description of the drawings
Fig. 1 is embodiment of the present invention structural representation.
Fig. 2 is embodiment of the present invention birds-eye view.
Detailed description of the invention
The present invention is made up of base 1, pressing plate 3, bolt 4 and nut 5, there is respectively a retaining groove both sides of base 1 with bolt of rear end plate 4 heads, bolt 4 is fixed by nut 5 by the bolt hole of pressing plate 3, also there is respectively a boss both sides at base, there is tapped bore at middle part at boss, mounting screw 2 in tapped bore, can regulate the position of pressing plate 3 by set screw 2, thereby reaches the object of adjusting gauge.On base, also have four bolts hole, by bolt 7, base is fixed on concrete crane beam or ground.
Bolt 4 can adopt Tang Shi screw bolt in order to improve its anti-loosening property.In the time using Tang Shi screw bolt, a nut 6 contrary with nut 5 rotation directions also to be installed on bolt 4.
Tang Shi screw thread be a kind of same thread segment have left and right two kinds of rotation directions screw thread, it both can with left hand thread engagement, can coordinate with right-hand screw thread again.Tang Shi screw bolt, in the time connecting, can use the nut of left and right two different rotation directions, sees Cheng great Xian chief editor, " mechanical design handbook ", Chemical Industry Press, 2012.
