Pedestal is equipped with several adjusting bolts close to four corner locations, pours plate and is fixed with height-regulating version by adjusting bolt.It is pre- to pour plate
It is embedded among cement, adjusting bolt adjusting height-regulating plate keeps each pedestal height and position consistent, until its flatness is in design requirement
It is fixed after in range by electric welding, pours board bottom face and be connected with several crotches, increase the connection area with ground, prevent its position
It moves.
Preferably, being provided with parallel shelf between two welded griders, parallel shelf is bonded with two welded griders.Parallel shelf is two length
Close to the long beam of welded grider, several connecting plates are connected between two long beams, connecting plate makes two long beam keeping parallelisms.
Preferably, welded grider is equipped with several mounting holes, line rail and rack gear are mounted in mounting hole by fastener.It is logical
Crossing fastener keeps line rail and rack gear consistent with mounting plate, guarantees its depth of parallelism, straightness and flatness.Meanwhile replacing tooth
Item and line rail are also more simple, conveniently.
Preferably, being provided with several spacer blocks between line rail and rack gear.Spacer block is arranged on welded grider at equal intervals, passes through
Spacer block guarantees the depth of parallelism between line rail and rack gear.
Preferably, the teeth directional of two rack gears is relatively or contrarily, each tooth position of two rack gears sets one-to-one correspondence.Tooth on rack gear
It corresponds, guarantees that the slide unit position being arranged on guide rail is accurate, reduce the abrasion to tooth.
Compared with prior art, the utility model has the beneficial effects that (1) reduces height, worker is facilitated to enter in guide rail
Operation；(2) line rail and rack gear combine, opposite higher using T-type rail precision；(3) guarantee the straightness of guide rail, rack gear and line rail
The flatness of the depth of parallelism and guide rail between the depth of parallelism, two guide rails.
