Two ends at said first crank shaft and second crank shaft are fixedly connected with crank respectively; Backup bearing is installed in the end of crank; Dividing each backup bearing at the two ends be in said first crank shaft and second crank shaft is in the rectangular distribution of same horizontal surface, and said upper frame is to be strut member with each backup bearing;
On four corner locations of said upper frame, be respectively arranged with guidance set, said guidance set has a pair of axis and is 90 degree layouts and locates first needle bearing and second needle bearing on the same horizontal surface, and vertical guidepost is fixedly installed on the pedestal; Said first needle bearing and second needle bearing are respectively to be guide rail with two rectangular on vertical guidepost sides, can vertically move along guide rail.
The constructional feature of the utility model high speed roller bed lifting mechanism also is: said drive motor is a both-end shaft extension motor; Said synchronous belt drive mechanism is two groups; Wherein one group of belt wheel transmission device is arranged on a shaft extension end of said first crank shaft and drive motor, and another group belt wheel transmission device is arranged on another shaft extension end of second crank shaft and drive motor.
Compared with present technology, the utility model beneficial effect is embodied in:
1, the utility model adopts crank to realize the up-down of roller bed upper frame, and through synchronous strap drive, simple in structure, cost is lower between drive motor and the crank shaft.
2, the utility model utilizes needle bearing to lead and supports, and needle bearing can bear bigger load, makes whole lifting mechanism can bear big load, is particularly suited on the high speed roller bed of weld car line, using.
3, the utility model is provided with both-end shaft extension motor, and it is more reasonable that driving and transmission device are distributed, and is stressed even, helps the raising of mechanism stable property.

Fig. 2 is the utility model supporting construction scheme drawing;
Fig. 3 is another view of the utility model supporting construction;
Fig. 4 is the utility model guidance set scheme drawing.
Label among the figure: 1 pedestal; 2 first are with synchronously; 3 first synchronous pulleys; 4 drive motor; 5 second are with synchronously; 6 vertical guideposts; 7a first crank shaft; 7b second crank shaft; 8a primary shaft bearing; 8b second bearing seat; 9 second synchronous pulleys; 10 cranks; 11 backup bearings; 12 upper frames; 13 guidance sets; 13a first needle bearing; 13b second needle bearing.
The specific embodiment
Referring to Fig. 1, Fig. 2, present embodiment high speed roller bed lifting mechanism is made up of pedestal 1, up-down driver element and liftable upper frame 12, and wherein pedestal 1 is for fixedly installing, and drive motor 4 is fixedly installed on the pedestal 1; The first crank shaft 7a that laterally arranges and the second crank shaft 7b are fixedly installed on the pedestal 1 through the primary shaft bearing 8a and the second bearing seat 8b respectively; Between the first crank shaft 7a and drive motor 4 be by first synchronous pulley 3 and first synchronously with 2 first synchronous belt drive mechanisms that constitute, be synchronously with 5 second synchronous belt drive mechanisms that constitute between the second crank shaft 7b and drive motor 4 by second synchronous pulley 9 and second.
As depicted in figs. 1 and 2; Two ends at the first crank shaft 7a and the second crank shaft 7b are fixedly connected with crank 10 respectively; Backup bearing 11 is installed in the end of crank 10; Dividing each backup bearing at the two ends be in the first crank shaft 7a and the second crank shaft 7b is in the rectangular distribution of same horizontal surface, and upper frame 12 is to be strut member with each backup bearing 11.
Like Fig. 1 and shown in Figure 4; On four corner locations of upper frame 12, be respectively arranged with guidance set 13; Guidance set 13 has a pair of axis and is 90 degree layouts and locates the first needle bearing 13a and the second needle bearing 13b on the same horizontal surface, and vertical guidepost 6 is fixedly installed on the pedestal 1; The first needle bearing 13a and the second needle bearing 13b are respectively to be guide rail with two rectangular on the vertical guidepost 6 sides, can vertically move along guide rail.
