In order to solve the above problems, the utility model adopts the following technical proposal.

The utility model provides a two compensating beam axles, includes the compensating beam, install the tripod outward, tripod upper end skin weld has the connecting plate, the tripod is connected in the compensating beam through the round pin axle in the big bearing, be connected with the backing roll through little bearing in the tripod, the arc convex surface is established to the upper surface of compensating beam, the backing roll extrusion is supported on the arc convex surface, through set up the arc convex surface with the axle center of erection pin on the compensating beam, adds at its tripod upside and establishes the backing roll, can support on the arc convex surface, improves its holding power, reduces the pressure of tripod king pin axle, makes its atress smooth and easy swing about even.

Furthermore, the arc-shaped convex surface and the pin shaft are arranged on the same axial center point, so that the arc-shaped convex surface is supported on the supporting roller to swing when the flat cross beam swings, the pressure born by the pin shaft on the tripod is reduced, and the swinging is smooth.

Furthermore, the supporting roller is distributed at the upper end of the tripod at two sides, and can be in triangular support with the pin shaft, so that the supporting force is improved.

Furthermore, the outer surface of the large bearing at the lower side of the tripod is connected with a first dust cover through a bolt, so that dust can be prevented from entering the large bearing from the outside.

Furthermore, the outer surface of the small bearing at the upper side of the tripod is connected with a second dust blocking cover through a bolt, so that dust can be prevented from entering the small bearing from the outside.

Compared with the prior art, the utility model has the advantages of:

(1) the arc-shaped convex surface which is coaxial with the mounting pin shaft is arranged on the balance beam, and the supporting roller is additionally arranged on the upper side of the triangular frame of the balance beam, so that the support beam can be supported on the arc-shaped convex surface, the supporting force of the balance beam is improved, the pressure of the main pin shaft of the triangular frame is reduced, and the balance beam can be stressed uniformly and smoothly swing left and right.

(2) The arc-shaped convex surface and the pin roll are arranged on the same axial center point, so that the arc-shaped convex surface is supported on the supporting roll to swing when the flat cross beam swings, the pressure born by the pin roll on the tripod is reduced, and the swinging is smooth.

(3) The supporting roller is distributed at the upper end of the tripod at two sides, and can be in triangular support with the pin shaft, so that the supporting force is improved.

(4) The outer surface of the large bearing at the lower side of the tripod is connected with a first dust cover through a bolt, so that dust can be prevented from entering the large bearing from the outside.

(5) The outer surface of the small bearing at the upper side of the tripod is connected with a second dust blocking cover through a bolt, so that dust can be prevented from entering the small bearing from the outside.
