Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1-5, a rail support frame is used in construction of urban rail traffic roadbed, includes support frame 4 and support arm 8, the bottom welded fastening of support frame 4 has cassette 10, the middle part at sleeper 1 is fixed to cassette 10 chucking, and cassette 10 is and inverts the spill, and the chucking is on sleeper 1 for keep the stability of support frame 4, the side of support frame 4 is fixed with fixed axle 11, the tip of fixed axle 11 articulates there is

bracing piece

2, and 2 bottom mounting of bracing piece are on the track bed, utilize bracing piece 2, can load the device and support after the rail, prevent that the device focus from squinting.

Threaded rod 6 of vertical setting is installed to 4 rotations of support frame, threaded rod 6 and the one end threaded connection of support arm 8, the upper end pin joint of threaded rod 6 is fixed with regulating wheel 5, through regulating wheel 5, can conveniently rotate threaded rod 6 to reciprocate through screw thread drive support arm 8, the inside of support frame 4 still vertically is fixed with guide pillar 12, support arm 8 movable sleeve is established on guide pillar 12, utilizes guide pillar 12, is favorable to keeping the stability of support arm 8, prevents that support arm 8 from reciprocating the in-process and deflecting, is favorable to keeping the stability of waiting to install the rail, prevents to drop.

The other end of support arm 8 is equipped with quad slit 801, movable mounting has square guide arm 9 in the quad slit 801, square guide arm 9's both ends are fixed with bearing roller 3 through the flange, and bearing roller 3 is used for rolling the support to the rail, is convenient for promote the rail through bearing roller 3 to will wait to install the rail and carry forward, deflector roll 14 is all installed at both ends about quad slit 801's inside, square guide arm 9 rolls and sets up between deflector roll 14, adopts square guide arm 9 can prevent self deflection, is favorable to the holding stability, utilizes deflector roll 14, can reduce the frictional resistance when square guide arm 9 removes, conveniently adjusts the installation distance of rail.
