Position-limit mechanism that dish moves up and down, rotates along spiral lifting column and move up and down handwheel, the biography that connects handwheel and pallet
Motivation structure.
Preferably, spiral lifting column is provided with rule along the vertical direction, and is provided with the scale of level at pallet top surface and refers to
Pin.
Preferably, base end face is provided with multiple locking and height-adjustable castor.
Preferably, position-limit mechanism includes the position-arresting disk being arranged on spiral lifting column and being connected in pallet top surface, described
Spiral lifting column outer surface is provided with a vertical groove, and described position-arresting disk is provided with the caging bolt penetrating in vertical groove.
Preferably, drive mechanism includes the support set being sleeved on spiral lifting column and can rotating along spiral lifting column
Cylinder and the drive block being sleeved on stop sleeve top, the outer surface of described stop sleeve is provided with a circle horizontal groove, described transmission
Block is provided with contiguous block, and the bottom of contiguous block penetrates in horizontal groove, and described stop sleeve can be freely rotatable around drive block；Described
Handwheel sleeve is contained in the bottom of stop sleeve.
Advantage of the present utility model in, theodolite is placed on the pallet of platform, freely can rise on screw thread lifting column
The whole height of falling tone, minimum be adjustable at ground, it is to avoid causes theodolite not take aim at because plane mirror placement location is low
Accurate problem；And on screw thread lifting column, it is furnished with scale, coordinate tuning drive gear, the real-time measurement to podium level can be realized；?
Under base equipped with four can lock, height-adjustable castor, fixing when can realize test, with ensure platform stability and
Completing the leveling of platform, castor also makes the handling process of this type theodolite placement platform become the most convenient simultaneously.
Accompanying drawing explanation
Fig. 1 is theodolite placement platform the first structural representation described in the utility model；
Fig. 2 is theodolite placement platform the second structural representation described in the utility model.
Detailed description of the invention
As shown in Figure 1 and Figure 2, a kind of theodolite placement platform being freely lifted, including base 1, for placing theodolite
Pallet 5, spiral lifting column 2 and drive the lowering or hoisting gear that moves up and down along spiral lifting column 2 of pallet；Lowering or hoisting gear includes
Can limit pallet 5 move up and down position-limit mechanism, rotate along spiral lifting column 2 and move up and down handwheel 3, connect handwheel
3 with the drive mechanism of pallet 5.
Spiral lifting column 2 is provided with rule 8 along the vertical direction, and is provided with the tuning drive gear of level at pallet 5 end face.Logical
Crossing and arrange rule 8 and tuning drive gear, can the most accurately indicate the height of theodolite, the minimum scale of rule is 1mm.
Base 1 bottom surface is provided with many.Individual lock and height-adjustable castor 9, can move freely placement platform, make longitude and latitude
The handling process of instrument placement platform becomes the most convenient.
Position-limit mechanism includes the position-arresting disk 6 being arranged on spiral lifting column 2 and being connected in pallet 5 end face, described spiral
Lifting column 2 outer surface is provided with a vertical groove, and described position-arresting disk 6 is provided with the caging bolt penetrating in vertical groove.Torr
When dish is without moving, caging bolt is locked in vertical groove, position-arresting disk 6 can be locked, and then restriction pallet 5 is transported
Dynamic；When needing position or the angle adjusting pallet 5, only caging bolt need to be unscrewed, i.e. can move freely pallet 5.
Drive mechanism includes stop sleeve 4 He being sleeved on spiral lifting column 2 and can rotating along spiral lifting column 2
Being sleeved on the drive block 7 on stop sleeve 4 top, the outer surface of stop sleeve 4 is provided with a circle horizontal groove, and drive block 7 is provided with
Contiguous block, the bottom of contiguous block penetrates in horizontal groove, and stop sleeve 4 can be freely rotatable around drive block 7；Handwheel 3 is sleeved on and props up
The bottom of support set cylinder 4.
The specific operation process of drive mechanism is: manual rotation's handwheel 3, and stop sleeve 4 rotates with handwheel 3, supports meanwhile
Sleeve 4 is underdrive on spiral lifting column 2, owing to drive block 7 is sleeved on the company on the top of stop sleeve 4, and drive block 7
