An Adjustable Shear Resistant Structure Used in Large Travel Gear

Abstract

The invention relates to an adjustable shear resistant structure used for a large travelling mechanism, which comprises equalizing beams, wherein the equalizing beams are movably connected with a trolley frame by a hinged shaft; first shear resistant blocks are symmetrically arranged on the trolley frame at an interval; mounting holes are formed in the equalizing beams; inner walls of the equalizing beams are symmetrically connected with fixing nuts; locking bolts sequentially penetrate through the mounting holes and the fixing nuts, are propped against the first shear resistant blocks, and are fixed by locking nuts. According to the adjustable shear resistant structure, the fixing nuts are symmetrically welded on the inner walls of the equalizing beams, the locking bolts are screwed in and are propped against the first shear resistant blocks, and the locking bolts and the first shear resistant blocks are bonded tightly and fixed by the locking nuts, so that the locking bolts exert shear resistant actions on thrust of the first shear resistant blocks, and a shear resistant effect is better; and a relative position between the trolley frame and the equalizing beams can be changed by adjusting the locking bolts, so that the problem that a position of the trolley frame is nonadjustable due to the fact that a wheel deviates from a track center is solved, and a mounting error is compensated.

Description

technical field [0001] The invention relates to construction machinery equipment, in particular to an adjustable anti-shear structure used for large traveling mechanisms such as ship unloaders, ship loaders, door cranes and the like. Background technique [0002] With the development of my country's economy, the construction of ports is advancing by leaps and bounds, and the requirements for equipment such as ship unloaders, ship loaders, and door cranes are getting higher and higher. Such as figure 1 As shown, in general, the connection form of the traveling mechanism of the carts such as the ship unloader, ship loader, and door crane is that the balance beam 101 and the trolley frame 104 are hinged through the hinge shaft 103, but this connection mode is affected by the hinge shaft 103 When the force in the axial direction is easily damaged by the shear force. The existing shear resistance forms are generally as follows: figure 1 As shown, the first shear block 102 and ...

Problems solved by technology

like figure 1 As shown, in general, the connection form of the traveling mechanism of the carts such as the ship unloader, ship loader, and door crane is that the balance beam 101 and the trolley frame 104 are hinged through the hinge shaft 103, but this connection mode is affected by the hinge shaft 103 When the force in the axial direction is easily damaged by shear force

The existing shear resistance forms are generally as follows: figure 1 As shown, the first shear block 102 and the second shear block 105 are welded at the hinge point between the balance beam 101 and the trolley frame 102, and the first shear block 102 is two pieces, which are arranged on the trolley frame 104 at intervals. The second shear block 105 is arranged between the two first shear blocks 102. The second shear block 105 is connected to the balance beam 101. The first shear block 102 and the second shear block 105 are closely attached and located in a line. On a straight line parallel to the hinge axis 103, but because the first shear block 102 and the second shear block 105 are not tightly bonded in this shear structure, the shear effect is poor and there is no adjustment capability. Once the wheel deviates from the center of the track, the position of the frame cannot be adjusted, the installation error cannot be compensated, and the phenomenon of wheel gnawing on the rail is prone to occur
