Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work Every other embodiment obtained, fall within the protection scope of the utility model.

Fig. 1-3 is please referred to, the utility model provides a kind of technical solution: a kind of city planning model device, including bottom plate 1, motor 2 and top plate 3 are equipped with the second shaft 25 in 1 top center of bottom plate, for rotating the sand table mould that 3 tops of top are placed Type, 25 one end of the second shaft are fixed with second bevel gear 24, are fixed with link block 31, link block 31 in 25 other end of the second shaft Top is fixedly connected with top plate 3.

At the top of top plate 3 be equipped with spring 32, the model GB/T 2089-2009 cylindroid helical-coil compression spring of this spring 32, Top plate 3 is fixed with workbench 33 by spring 32, because sand table model is with the difference of city planning design, weight everywhere is not yet Together, spring 32 can be used to the sand table model on 33 top of shock-absorbing support workbench, open up anti-skid chequer in the upper surface of workbench 33, prevent Only sand table model slides, and is socketed with grip block 34 at the both ends of workbench 33, and grip block 34 is L-type structure and itself and workbench 33 It is slidably connected, wherein L-type structure prevents to be displaced, fixed sand towards inside for clamping the sand table model on workbench 33 Disk model is stronger.

At 1 bottom of bottom plate, four end by being welded with supporting leg 11, motor is horizontally fixed between four supporting legs 11 Fixing seat 12,12 top side of motor fixing seat have been bolted motor 2, and motor 2 and external power supply are electrically connected, The output shaft of motor 2 is fixed with first rotating shaft 22 by shaft coupling 21, the end of first rotating shaft 22 is equipped with first bevel gear 23, first bevel gear 23 engages connection with second bevel gear 24.

First bevel gear 23 is driven to rotate by opening motor 2, because first bevel gear 23 is engaged with second bevel gear 24 Connection, so that second bevel gear 24 be driven also to rotate with it, second bevel gear 24 is mutual by the second shaft 25 and link block 31 It is fixedly connected, so that the workbench 33 at 31 top of link block be driven to rotate, and then the sand table model on 33 top of workbench is driven to turn Dynamic, 360 ° of rotations make staff's observation more convenient, do not need to walk about.

For better rotary work-table 33, the second shaft 25 is rotatablely connected by axle sleeve 13 with bottom plate 1, the mistake of rotation Journey prevents the rotation contact surface of the second shaft of abrasion 25 with bottom plate 1, naturally it is also possible to add bearing to increase rotating effect.

For the sand table model that better 33 top of stationary work-table is placed, the two sides of workbench 33 are offered up and down Groove 331 is equipped with inside groove 331 and adjusts screw 332, and workbench 33 is fixedly connected by adjusting screw 332 with grip block 34, By adjusting the fixed sand table model of grip block 34 of screw 332, movable shifting phenomena is prevented, adjusts screw 332 in groove Inside 331, when sand table model is placed on workbench 33, influence caused by jacking up sand table model there will not be.

In order to control the revolving speed of motor 2, it sets motor 2 to the phase asynchronous ac motor of model Y132S-8, And motor 2 is changed into a-c cycle by frequency converter to control revolution, nothing adds slip loss, efficiency in frequency control Height, speed-regulating range width, or start-stop more for low-load runing time run more frequently occasion, can achieve economize on electricity and guarantor Protect the purpose of motor.

Spring 32 is displaced during rotation in order to prevent, by spring 32 by spacing collar 321 respectively with top plate 3 and Workbench 33 is fixedly connected, and the top and bottom of spring 32 is respectively and fixedly provided with spacing collar 321, and spring 32 is evenly distributed on 3 He of top plate Between workbench 33, the effect of support and damping is also functioned to sand table model.

As another embodiment, it can be fixed with self-locking Universal pulley in the bottom end of supporting leg 11, is moved easily this dress Set suitable display location.

Working principle: being placed on 33 top of workbench for sand table model, and top plate 3 passes through 32 stationary work-table 33 of spring, because For sand table model with the difference of city planning design, weight everywhere is also different, and spring 32 can be the sand table mould on 33 top of workbench Type provides the effect of support damping, opens up anti-skid chequer in the upper surface of workbench 33, prevent sand table model from sliding, in workbench 33 both ends are socketed with grip block 34, grip block 34 be L-type structure and its be slidably connected with workbench 33, wherein L-type structure court Inwardly, for clamping the sand table model on workbench 33, prevent to be displaced, fixed sand table model is stronger, opens electricity Motivation 2 drives first bevel gear 23 to rotate, because first bevel gear 23 engages connection with second bevel gear 24, to drive the second cone Gear 24 also rotates with it, and second bevel gear 24 is mutually permanently connected by the second shaft 25 with link block 31, thus the company of drive The workbench 33 for connecing the top of block 31 rotates, and then drives the sand table model rotation on 33 top of workbench, rotates by 360 °, allows work It is more convenient to make personnel's observation, does not need repeatedly to walk about.
