Detailed description of the invention
Describe the specific embodiment of the present invention below in conjunction with the accompanying drawings in detail.
Synchronous lifting according to the present invention move in and out mechanism population structure as it is shown in figure 1, this mechanism include four lift columns, three power transmission shafts with its belonging to shaft joint, one move in and out drive mechanism, two mobile load bearing cross beams, handles.Move in and out drive mechanism and mobile load bearing cross beam composition moves in and out mechanism.Between lift columns 1 and lift columns 7, connected together by mobile load bearing cross beam 2 and 5 respectively between lift columns 3 and lift columns 4, transmitting power by two power transmission shafts 6 and a power transmission shaft 8 between each lift columns, power transmission shaft 6 two ends are connected with gear shaft 23 by universal joint shaft joint.Separately it is connected between lift columns 1 with lift columns 7 and moves in and out mechanism 9.Mobile 2 two lift columns 1 and 7 of load bearing cross beam connect together and form a unit.Mobile 5 two lift columns 3 and 4 of load bearing cross beam connect together and form another unit.Promote the handle 10 being provisionally attached in lift columns 1 by rotation when of moving in and out drive mechanism to realize, the when of removal, be also adopted by handle manual actuation.
In order to ensure Synchronous lifting, lifting tooth roller box it is provided with in lift columns, gear-box needs correctly to be assembled, as shown in Figure 2, dead eye in bearing block 24, location side plate 27 needs to align axle center, so being machined with two pairs of dowel holes on gear-box 211, being used for positioning bearing seat 24 a pair, another is to being used for positioning side plate 27.Also have corresponding dowel hole on bearing block 24 and side plate 27, use during assembling these location holes penetrate alignment pin positioning bearing seat 24 and side plate 27 with ensure both dead eye to the heart.Bevel gear 29, bearing 22, bearing 28, worm screw 210 and round nut 21 are first fitted together, and adjust its preload by round nut 21.Then round nut 21, bearing 22, bearing 25, bevel gear 26 are contained in inside part 24 with axle 23 in advance, then assembly are arranged on part 211.With the gap between clearance gauge detection bevel gear 26 and bevel gear 29, adjust gap by the pad inside increase and decrease assembly 24, be allowed to arrive the requirement of regulation.As a example by the only gear-box in lift columns 7 described above, accompanying drawing 4 and related content thereof are shown in the explanation of concrete drive mechanism.
As best shown in figures 3 a and 3b, move in and out mechanism and there are mobile load bearing cross beam and drive mechanism two parts.At the two ends of mobile load bearing cross beam 2, two bearings 31 are installed, are individually fixed on lift columns 1 and the lifting tooth roller box within lift columns 4.The standing part of a slide rail 33 is respectively installed in two sides of crossbeam 2, and the slipper of slide rail 33 is then fixed with sliding rail frame 34, makes sliding rail frame 34 by slide rail 33 can crossbeam 2 be slidably relatively.Drive mechanism is utilized to drive mobile load bearing cross beam, being described as follows of the concrete structure of drive mechanism.Screw rod 38 two ends are respectively fixed in lift columns 1 and lift columns 4 with a bearing block 37 and bearing block 310.Power transmission shaft 313 is arranged on bearing block 312 and 314 also by bearing, on bearing block 312 and 314 lifting tooth roller boxs being arranged within lift columns 4.One end of power transmission shaft 313 is provided with belt wheel, can transfer power on screw rod 38 with Timing Belt 311, and the other end is shaped with square toes, is used for installing handle when needed.The nut that on screw rod 38, surface cover is connected with the sliding rail frame 34 of mobile load bearing cross beam, therefore when lift mechanism lifts to top, after i.e. two mobile load bearing cross beams cross the top of four lift columns, with rotatable handle power transmission shaft 313, screw rod 38 just can be driven to rotate, and the nut on screw rod 38 just can drive load weight on two one slide rail framves 34 to move in and out along crossbeam 2.
As shown in Figure 4, rotate the handle as driving link, drive link I is driven to rotate, bevel gear 29, bevel gear 103, worm screw 210, worm screw 303, universal joint 403, universal joint 404 and drive link I are fixed together, so rotating together with regard to band dynamic bevel gear 29, bevel gear 103, worm screw 210, worm screw 303, universal joint 403, universal joint 404.Bevel gear 29 engages with bevel gear 26, and bevel gear 26, universal joint 401, universal joint 402, worm screw 301 are fixed together, thus the rotation of bevel gear 102 has just driven bevel gear 26, universal joint 401, universal joint 402, worm screw 301 to rotate together.Bevel gear 103 engages with bevel gear 104, and bevel gear 104, universal joint 405, universal joint 406, worm screw 304 are fixed together, and has just driven bevel gear 104, universal joint 405, universal joint 406, worm screw 30 to rotate together so bevel gear 103 rotates.Worm screw 301 engages with worm gear 201, worm screw 302 engages with worm gear 202, worm screw 303 engages with worm gear 203, worm screw 304 engages with worm gear 204.Thus turning handle, the most just drive worm gear 201, worm gear 202, worm gear 203, worm gear 204 synchronous axial system, and then drive weight to be lifted up.
The preferred embodiment of the simply present invention described in this specification, above example is only in order to illustrate technical scheme rather than limitation of the present invention.All those skilled in the art, all should be within the scope of the present invention under this invention's idea by the available technical scheme of logical analysis, reasoning, or a limited experiment.
