Abstract
The utility model discloses a parallel lifter. The parallel lifter comprises a platform and a plurality of supporting components, and is characterized in that each supporting component is formed by a cylindrical rack, a gear shell, a flange and a flange fixing device, wherein the inner structure of the gear shell comprises an oilless bearing, a woodruff key, an oilless lining, a gear and connection round steel, the cylindrical rack is meshed with the gear, the gear and the woodruff key fix a key pin through the woodruff key, and the gear is supported by the bearing, the oilless lining and the connection round steel. The parallel lifter has the advantages that the spur gears are connected and matched with circular two-sided racks, the synchronous error of supporting points can reach 0.5 mm to the minimum, it is guaranteed that the supporting points ascend and descend synchronously, and the platform of the lifter can ascend and descend stably; noise generated when a triangular support is pulled obliquely is reduced and noise pollution during construction operations is reduced.
Description
Technical field
The utility model belongs to jacking system technical field, is specifically related to a kind of parallel lifter.
Background technology
Parallel lifter is widely used in the industries such as automation of industry, warehouse logistics, medical facilities.But its bearing of lifter using is in the market linear bearing, and when work, lifting parallelism error is larger.
For example, application number is 201310026769.6 invention, a kind of high-rise escape self-rescue lifter is disclosed, it comprises housing, collection rope sheave, wheel shaft, withdrawing rope, gib head, rocking arm drive spindle, driven wheel, handle, safety strap, it is characterized in that: housing is made up of two symmetrically arranged spill housings, on collection rope sheave, there is wheel shaft through-hole, wheel shaft is through taking turns after shaft through-hole, wheel shaft two ends are positioned at collection rope sheave both sides, on two spill housings, correspondence is provided with fixed orifice, wheel shaft two ends are through fixed orifice setting, on the wheel shaft that collection rope sheave is twice, be provided with dish spring, the clamp nut that is arranged on wheel shaft both ends is tightened, disc spring pressing is being collected between rope sheave and spill housing.
But the disclosed technical scheme of above-mentioned utility model, can not solve in the process of elevator rising or decline the technical matters that elevator landing teetertotters.
Utility model content
For the above-mentioned technical matters of determining, the utility model discloses a kind of parallel lifter, comprise platform and several support components, described support component is made up of cylinder tooth bar, gear hub, flange and flange fixing device, described gear hub inner structure comprises oilless metal, semi-round key, without oily lining, gear and connection round steel, described cylinder tooth bar is connected with described engaged gears, described gear and described round steel are by the fixing key pin of described semi-round key, described bearing and described without gear described in oily lining and described connection Rod Bracing.
Further, described support component is two to four, and by the symmetrical connection between two in turn of described round steel.
Further, described flange fixing device is flange check screw.
Further, described gear is spur gear.
Further, described flange and described flange fixing device are aluminum or No. 45 steel.
Further, described gear hub is made up of upper gear housing and lower tooth hub, and described gear hub is gear aluminum hull.
A kind of parallel lifter of the utility model compared to the prior art, its advantage is: first, parallel lifter is to rely on being linked between spur gear and circular jersey tooth bar, and the I of the synchronous error of the strong point reaches 0.5mm, ensure described strong point synchronization lifting, and then realize and fall the steady lifting of machine platform and decline.The second, the noise of reduction oblique pull A-frame, reduces the noise emission in construction operation.
