The defects such as lifting precision is low, disclose one and lift more steadily, control more accurate ground well drive system.
Below by embodiment, and combine accompanying drawing, technical scheme is made more specifically
Bright.
A kind of ground well drive system includes elevating mechanism 1, limits the gantry type guiding of elevating mechanism motion path
Position-limit mechanism, control the drive mechanism of elevating mechanism and be arranged on outside elevating mechanism with elevating mechanism even
Connect balance weight mechanism.
As it is shown in figure 1, the elevating mechanism 1 in this ground well drive system is arranged at gantry type guide and limit machine
Between structure, elevating mechanism includes a lifting structure base plate.This lifting structure base plate relies on drive mechanism,
Its lifting is drawn by drive mechanism.Lifting structure base plate is positioned at the top of drive mechanism, and in drive mechanism
Support member directly contact.
Above-mentioned drive mechanism is arranged on the lower section of elevating mechanism 1, including motor 31, shaft coupling 32, leading screw
33, feed screw nut 34 and support member.Wherein, output is transmitted by described motor 31 by shaft coupling 32
To leading screw 33.Leading screw 33 runs through above-mentioned lifting platform and is supported in the central authorities of whole elevating mechanism 1, therefore silk
The length of thick stick 33 determines the liftable range of movement of elevating mechanism.Described feed screw nut is simultaneously attached to rise
On descending mechanism 1 and leading screw 33, i.e. the lifting being secured transverse in elevating mechanism 1 knot of feed screw nut 34
On structure base plate, the longitudinal direction of feed screw nut 34 be then and leading screw 33 screw thread hitch so that this feed screw nut 34
Ten word directions are positioned.Described support member accepts leading screw 33 and elevating mechanism 1, is particularly located at
Between shaft coupling 32 and feed screw nut 34, leading screw 33 is through this support member simultaneously.Support member is wrapped again
Include support 351 and leading screw supporting 352: described support 351 has door type structure, is located at shaft coupling 32
On；Described leading screw supporting 352 is also secured on support 351 and leading screw 33, i.e. leading screw supporting 352
Be secured transverse on described support 351, leading screw supporting 352 be vertically fixed on leading screw 33 so that
Leading screw supporting 351 is also completely fixed in ten word directions, it is possible to firm support leading screw 33 and elevator
The gravity of structure 1.
Illustrating with the embodiment shown in Fig. 1: motor 31 drives, shaft coupling 32 makes motor 31 export
It is converted into the rotary motion of leading screw 33.It is fixed on the feed screw nut 34 of lifting structure base plate simultaneously and leading screw
33 screw thread hitch, leading screw 33 rotates, and feed screw nut 34 then moves upward or downward along leading screw,
By the elevating movement that convert rotational motion is elevating mechanism 1, this lifting process can be real by motor 31 rotating speed
Existing stepless time adjustment controls, adjustable height precise control, precision height, can stop lifting at arbitrary height.

The loop of tensioning, the inner side in steel wire rope loop is relatively fixed with elevating mechanism 1, due to elevating mechanism 1
Stroke is not over the half way in this steel wire rope loop, therefore on elevating mechanism 1 is under drive mechanism drives
When rising or decline, synchronize to rise or fall inside the steel wire rope loop connected with elevating mechanism 1, with this together
Time, it is positioned at the counterweight 43 outside steel wire rope loop the most down or up, due to all counterweights 43
Quality sum is equal to the quality of elevating mechanism 1 so that the mistake that leading screw 33 rises at traction elevating mechanism 1
Cheng Zhong, loads almost nil, thus can reach the effect improving leading screw 33 rotating speed, alleviates all simultaneously
The load of support part part, it is ensured that the service life of part.
Above-mentioned gantry type guide and limit mechanism includes channel-section steel 21 and bearing 22.Preferably channel-section steel is heavy wall channel-section steel,
Preferably bearing is composite bearing, and the gantry type guide and limit mechanism of both compositions can limit elevating mechanism 1 and exist
The motion of upper horizontal direction, stops elevating mechanism 1 to be shaken in lifting process, is that lifting process is put down
Surely.
Preferably, in embodiment as shown in Figure 1, gantry type guide and limit mechanism is positioned at elevating mechanism 1
With between balance weight mechanism, balance weight mechanism is crossed gantry type guide and limit mechanism and is connected with elevating mechanism 1.Limit
In the guiding mechanism of position, composite bearing is connected with elevating mechanism 1；Channel-section steel position is fixed, will not be with elevator
The lifting of structure 1 and change.Other diverse location structure designs with identical function also belong to the present invention and protect
Protect scope.
Comprehensive above said content, the ground well drive system that the present invention provides has the advantage that
(1) this ground well drive system is when ground well lifts, and uses the transmission that motor combines with leading screw
Pattern.Motor drives screw turns, and feed screw nut drives elevating mechanism lifting, makes rotary motion effectively
