Summary of the invention
The utility model aim to provide a kind of can conveniently realize workpiece level to the hydraulic lifting dolly of displacement.
Technical solution of the present utility model is as follows:
A kind of hydraulic lifting dolly, comprise wheel, underframe, upper ledge, scissor arm, elevating ram, roller, runway, described wheel is installed on below underframe, above underframe, runway is installed, at least form and the lifting mechanism driven by elevating ram by two scissor arms are hinged, the upper end of lifting mechanism is connected with upper ledge, wherein, the lower end of a scissor arm is provided with roller, this roller is positioned at above-mentioned runway, it is characterized in that: described upper ledge is provided with many parallel can free rolling carrying roller, every root carrying roller is installed on the frame of upper ledge by the bearing at its two ends, a holding device is also installed in described upper ledge, this holding device is by left-right rotary screw mandrel, left-handed nut seat, right handed nuts seat, left clamping plate, right clamping plate, handwheel forms, left-right rotary screw mandrel is installed on upper ledge by bearing, its one end is connected with handwheel, left clamping plate are connected with left-handed nut seat, right clamping plate are connected with right handed nuts seat.
The utility model is owing to adopting technique scheme, workpiece is placed on the carrying roller of upper ledge, because carrying roller all can roll freely, workpiece can easily move perpendicular to the installation direction of carrying roller under external force, realizes workpiece and finely tunes to the installation direction perpendicular to carrying roller.Achieve goal of the invention easily.
When rotation hand wheel rotates, handwheel drives screw mandrel to rotate, screw mandrel drive is left-handed, right handed nuts seat moves, left-handed, right handed nuts seat drives left clamping plate, right clamping plate respectively, when handwheel clickwise, drives left-handed, right handed nuts seat to move inward, thus drive two clamping plate to move to centre, clamping work pieces, on the contrary during handwheel conter clockwise, holding device unclamps.
It is easy to operate when above-mentioned holding device makes to realize workpiece displacement.
Further technical scheme is:
Described left clamping plate and left-handed nut seat are detachable connection, and right clamping plate and right handed nuts seat are detachable connection.
The scheme the most easily realizing above-mentioned connection is clamping, as: left-handed nut seat has the draw-in groove that width is identical with left clamping plate thickness, right handed nuts seat has the draw-in groove that width is identical with right clamping plate thickness, left and right clamping plate block respectively and insert in each self-corresponding draw-in groove, thus complete clamping.
The advantage of this technical scheme is, when needing to realize the installation direction of workpiece to carrying roller and finely tuning, can take off wherein one piece of clamping plate, rotation hand wheel, another block clamping plate are driven by corresponding nut seat, promote workpiece.
The technical scheme of another step is:
The surface of described carrying roller, for having the material of certain elasticity and hardness, as nylon, rubber etc., preferably adopts nylon.
So, during workpiece motion s, surface is not easily scratched.
Accompanying drawing explanation
Below with reference to drawings and Examples, the utility model is described in further details.
Accompanying drawing 1 is the structural representation of the utility model embodiment.
Accompanying drawing 2 is the structural representation of attached middle upper ledge embodiment illustrated in fig. 1.
In accompanying drawing, each sequence number is respectively: 1, wheel; 2, runway; 3, underframe; 4, hydraulic power unit; 5, elevating ram; 6, roller; 7, scissor arm; 8, scissor arm; 9, upper ledge; 10, bearing; 11, left clamping plate; 12, carrying roller; 13, left-handed nut seat; 14, left-right rotary screw mandrel; 15, right clamping plate; 16, right handed nuts seat; 17, handwheel.
Detailed description of the invention
See accompanying drawing 1, hydraulic lifting dolly shown in the utility model embodiment adopts scissor bassinet structure, by wheel 1, underframe 3, upper ledge 9, scissor arm 7,8, elevating ram 5, roller 6, runway 2 etc. form.Wheel 1 is installed on below underframe 3, runway 2 is installed, by the hinged lifting mechanism formed of two scissor arms 7,8 above underframe 3, power lifting is provided by elevating ram 5, the upper end of two scissor arms 7,8 is connected with upper ledge 9, wherein, the lower end of scissor arm 8 is provided with roller 6, and this roller 6 is positioned at above-mentioned runway 2, and workpiece is placed on upper ledge.When elevating ram 8 works, the roller 6 of scissor arm 8 lower end moves along runway 2, and scissor arm lifts upper ledge 9 upward movement.With existing hydraulic lifting dolly unlike, upper ledge 9 is provided with 6 parallel can free rolling carrying roller 12, every root carrying roller is installed on the frame of upper ledge 9 by the bearing 10 at its two ends, the surface of each carrying roller is all enclosed with nylon, a holding device is also installed in described upper ledge, this holding device is by left-right rotary screw mandrel 14, left-handed nut seat 13, right handed nuts seat 16, left clamping plate 11, right clamping plate 15, handwheel 17 forms, left-right rotary screw mandrel is installed on upper ledge by bearing (not indicating in figure), one end of left-right rotary screw mandrel 14 is connected with handwheel 17, left-handed nut seat 13 has the draw-in groove that width is identical with left clamping plate 11 thickness, right handed nuts seat 16 has the draw-in groove that width is identical with right clamping plate 15 thickness, left, right clamping plate block respectively and insert in each self-corresponding draw-in groove, thus complete clamping.
When rotation hand wheel 17 clickwise, left-handed, right handed nuts seat moves to centre, thus drives two clamping plate to move to centre, clamping work pieces, otherwise during handwheel conter clockwise, holding device unclamps.
When needing workpiece to finely tune to the installation direction perpendicular to carrying roller, apply the external force of the installation direction perpendicular to carrying roller, because carrying roller all can roll freely, workpiece can easily move perpendicular to the installation direction of carrying roller under external force.
