Abstract
The invention relates to a guide screw type ascending seat. The guide screw type ascending seat is characterized by comprising a guide screw, wherein a left nut and a right nut are arranged on the left side and right side of the guide screw respectively; a first upper supporting plate and a first lower supporting plate are arranged on the left nut; a second upper supporting plate and a second lower supporting plate are arranged on the right nut; a first synchronizing gear is arranged at an end part of the first upper supporting plate; a third synchronizing gear is arranged at an end part of the first lower supporting plate; a second synchronizing gear is arranged at an end part of the second upper supporting plate; a fourth synchronizing gear is arranged at an end part of the second lower supporting plate; the first synchronizing gear is meshed with the second synchronizing gear, and the third synchronizing gear is meshed with the fourth synchronizing gear; the first synchronizing gear and the second synchronizing gear are fixed on an upper platform through a rotating shaft respectively; and the third synchronizing gear and the fourth synchronizing gear are fixed on a fixed rack through a rotating shaft respectively. The guide screw type ascending seat is simple in structure, convenient to move and reliable to use, and avoids damages and rejections of motor stators caused by insufficient supporting force in operation.
Description
Technical field
The present invention relates to a kind of seat of ascending a height, especially a kind ofly be used for the motor stator assembling and the time increase and the screw mandrel formula of the load-carrying seat of ascending a height, belong to field of mechanical technique.
Background technology
Need lift upset during the assembling of Large Electric machine stator, at this moment need one and can increase the supporting point of load-carrying again arbitrarily in the place ahead of suspension centre; Not enough like support force, the motor stator skew takes place in operation easily, thereby causes motor stator to damage the phenomenon of scrapping.
Summary of the invention
The objective of the invention is to overcome the deficiency that exists in the prior art, a kind of screw mandrel formula seat of ascending a height is provided, simple in structure, conveniently moving uses reliably, avoided in the operation because of support force is not enough, and the motor stator that causes damages the phenomenon of scrapping.
According to technical scheme provided by the invention, the said screw mandrel formula seat of ascending a height is characterized in that: comprise screw mandrel, left and right left nut and the right nut of being provided with respectively on said screw mandrel; First upper backup pad and first lower supporting plate are set on left nut; Second upper backup pad and second lower supporting plate are set on right nut; In the end of first upper backup pad first synchromesh gear is set; In the end of first lower supporting plate the 3rd synchromesh gear is set, second synchromesh gear is set, the 4th synchromesh gear is set in the end of second lower supporting plate in the end of second upper backup pad; Said first synchromesh gear and the engagement of second synchromesh gear, the 3rd synchromesh gear and the engagement of the 4th synchromesh gear; Said first synchromesh gear and second synchromesh gear are fixed on the upper mounting plate through rotation axis respectively, and the 3rd synchromesh gear and the 4th synchromesh gear are fixed on the fixed mount through rotation axis respectively.
One end of said screw mandrel is provided with handwheel.
Screw mandrel formula of the present invention simple, the conveniently moving of holder structure of ascending a height uses reliably, avoided in the operation because of support force is not enough, and the motor stator that causes damages the phenomenon of scrapping.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Embodiment
Below in conjunction with concrete accompanying drawing the present invention is described further.
As shown in the figure: the screw mandrel formula seat of ascending a height comprises left nut 1, first upper backup pad 2, upper mounting plate 3, first synchromesh gear 4, screw mandrel 5, handwheel 6, fixed mount 7, right nut 8, second upper backup pad 9, first lower supporting plate 10, second lower supporting plate 11, second synchromesh gear 12, the 3rd synchromesh gear 13, the 4th synchromesh gear 14 etc.
The present invention includes screw mandrel 5, an end of screw mandrel 5 is provided with handwheel 6, and screw mandrel 5 is realized rotating through rotating handwheel 6; Left and right left nut 1 and the right nut 8 of being provided with respectively on said screw mandrel 5; First upper backup pad 2 and first lower supporting plate 10 are set on left nut 1; Second upper backup pad 9 and second lower supporting plate 11 are set on right nut 8, first synchromesh gear 4 is set in the end of first upper backup pad 2, the 3rd synchromesh gear 13 is set in the end of first lower supporting plate 10; In the end of second upper backup pad 9 second synchromesh gear 12 is set, the 4th synchromesh gear 14 is set in the end of second lower supporting plate 11; Said first synchromesh gear 4 and second synchromesh gear 12 are fixed on the upper mounting plate 3 through rotation axis respectively, and the 3rd synchromesh gear 13 and the 4th synchromesh gear 14 are fixed on the fixed mount 7 through rotation axis respectively; Said first synchromesh gear 4 and 12 engagements of second synchromesh gear, the 3rd synchromesh gear 13 and 14 engagements of the 4th synchromesh gear.
The course of work of the present invention: motor stator is placed on the upper mounting plate 3; Rotate handwheel 6, realize the rotation of screw mandrel 5, when left nut 1 and right nut 8 under the effect of screw mandrel 5 during the rotation of up time direction; Supporting bracket moves to the centre, thereby upper mounting plate 3 slowly raises under the effect of synchromesh gear; When opposite spin handwheel 6,3 of upper mounting plates slowly reduce.The present invention is easy to operate, and is simple and reliable for structure, and manufacturing expense is low, is the indispensable instrument that the medium-and-large-sized motor stator of electromechanics trade advances the shell upset.
