During industry, collapsible lorry-mounted crane rotates mechanism by it and realizes rotation function, to meet the laying needs of gapless line, and
There are following some shortcomings in the mechanism that rotates of current common collapsible lorry-mounted crane：First is that rotating the rotation driving of mechanism
Mode is the rotation of motor-driven gear disk, is usually also needed using retarder, therefore cause the structure for rotating mechanism more multiple
Miscellaneous, manufacturing cost is high, and assembly and maintenance are not very convenient；Second is that when the rotation of motor driven rotary shaft, it can be to rotary shaft
Radial forces are generated, makes rotary shaft unbalance stress, a degree of deflection occurs, after long-term work, lead to rotary shaft office
Portion's abrasion is more serious, so as to shorten its service life.
Utility model content
The purpose of this utility model be exactly provided to solve above-mentioned deficiency one kind it is simple and compact for structure, can effectively drop
Low manufacturing cost, and not easy to wear, what the collapsible gapless line that can substantially prolong the service life entered scouring machine automatically rotates mechanism.
In order to solve the above-mentioned technical problem technical solution that the utility model uses is as follows：
What collapsible gapless line entered scouring machine automatically rotates mechanism, it includes support, pairs of cylinder body, cylinder, push rod, rotation
Shaft, pairs of bearing, thrust bearing, pairs of limit pulley and cover board, opened up inside the support it is fluted, it is described to push away
Power bearing is mounted in the bottom of the groove, the bottom of rotary shaft is provided with annular supporting plate, it is living that rotary shaft passes through annular supporting plate
Moving frame is set on thrust bearing, and the pairs of bearing is separately mounted to inside grooves, and pairs of bearing is nested with respectively to be rotated
On the outside of axis, gear is provided on the rotary shaft lateral wall between matched bearings, the fixed lid of the cover board sets the groove in support
Top offers through-hole on the cover board, and the upper end of the rotary shaft is pierced by from the through-hole of cover board, in the upper end of rotary shaft
It is provided with supporting plate, the cylinder is fixedly mounted on the lateral wall of support, and is connected with the groove of support, the pairs of cylinder
Body is respectively and fixedly installed to the both ends of cylinder, and is connected with inner barrel, and the push rod activity is set in cylinder, is pushing away
The both ends of bar are respectively arranged with piston, and the both ends of push rod pass through piston activity holding in pairs of cylinder body respectively, pushing away
One side of bar is provided with tooth row, and push rod is meshed by tooth row with gear, and the pairs of limit pulley difference is rotationally
It is movably arranged in cylinder, the other side of push rod fits with pairs of limit pulley, on the end of pairs of cylinder body respectively
Offer oilhole.
Sealing ring is equipped on the lateral wall of the piston.
Limit plate is provided in the rotary shaft being located at below cover board.
The utility model is using the attainable beneficial effect of above-mentioned technical solution institute：Pass through hydraulic-driven push rod two
The piston of end moves in pairs of cylinder body, and drives gear, rotary shaft and supporting plate to rotate by tooth row, to realize rotation
Rotating function avoids the driving method that the collapsible lorry-mounted crane of tradition uses motor, enormously simplifies the knot for originally rotating mechanism
Structure reduces its occupied space, significantly reduces manufacturing cost, and assembly and maintenance are very convenient；Gear is arranged pairs of
Bearing between, when the rotation of tooth row sliding tooth wheel, rotary shaft stress equalization can effectively prevent rotary shaft to generate deflection and show
As extending the service life for originally rotating mechanism to reduce the generation of wear phenomenon；Pairs of limit pulley can be to push rod
Good position-limiting action is played in moving process, is led when avoiding the rotation of tooth row sliding tooth wheel by outside reaction force
The piston excursion of cause is worn, to further improve the service life for originally rotating mechanism.
