Abstract
The utility model relates to lifting equipment, in particular to a hand-operated lead screw lifting device. The lead screw lifting device structurally comprises an inner casing and a steel plate base seat, wherein the bottom of the inner casing is welded to the steel plate base seat, the inner casing is a square pipe, the upper portion of the inner casing is welded to a nut, the nut is arranged on the periphery of a lead screw, an outer casing is arranged outside the inner casing, the outer casing is a square pipe and is welded to channel steel provided with a nut, a crank is welded to the lead screw through a supporting piece, a thrust ball bearing is arranged at the upper portion of the lead screw, and a straight-through type forced filling oil cup is arranged at the upper portion of the outer casing. Compared with the prior art, the lead screw lifting device has the advantages of being simple in structure, small in size, and favorable for conveying of a sprinkler, and the lifting height can be adjusted conveniently.
Description
Technical field
The utility model relates to a kind of jacking equipment, especially a kind of shaking screw lifting device.
Background technology
At present, be lifting and the transportation of finishing the reel sprinkling irrigation machine chassis, the normal equipment that adopts is lifting table, and is in the majority with hydraulic structure, and it is excessive that such jacking equipment promotes amplitude, and function singleness is arranged, and volume is large, and transportation is inconvenient, makes the shortcomings such as the chassis is unstable.
Summary of the invention
Technical assignment of the present utility model is for above weak point, provides a kind of volume little, can finish easily the screw lifting device of elevating function.The technical scheme that its technical matters that solves the utility model adopts is: the utility model structure comprises the bottom of inner sleeve and steel plate base weld together, inner sleeve is a square tube, inner sleeve top and screw weld together, screw is arranged on the periphery of leading screw, inner sleeve outside arranges outer sleeve, and outer sleeve is square tube, outer sleeve and with the channel-section steel weld together of nut, crank is to be welded on above the leading screw by strut member, and leading screw top arranges thrust ball bearing.
Described outer sleeve top arranges the through type forced filling oil cup.
The utility model is compared with existing technology, have following characteristics: the utility model is provided with leading screw and crank, use the elevating function of leading screw, cooperate the operation of crank, by selecting different hand of rotation, realize lifting and reduction to the irrigation sprinkler chassis height, volume is little, cost is low, and is easy to operate.
Description of drawings
Further specify below in conjunction with 1 pair of the utility model of accompanying drawing.
Accompanying drawing 1 is the structural representation of screw lifting device.
Among the figure: 1, inner sleeve, 2, outer sleeve, 3, leading screw, 4, the through type forced filling oil cup, 5, thrust ball bearing, 6, crank, 7, screw.
The specific embodiment
With reference to explaining below 1 pair of screw lifting device work of the present utility model of Figure of description.
The utility model structure is bottom and the steel plate base weld together of inner sleeve 1, and inner sleeve 1 is the square tube of 50x50.Inner sleeve 1 top and screw 7 weld togethers.Screw 7 is arranged on the periphery of leading screw 3, and inner sleeve 1 outside arranges outer sleeve 2, and outer sleeve is comprised of the square tube of 60x60, outer sleeve and with the channel-section steel weld together of nut.Crank 6 is to be welded on above the leading screw 3 by strut member.Leading screw 3 tops arrange thrust ball bearing 5.5 pairs of leading screws 3 of thrust ball bearing play the effect of supporting and reducing friction, so that rotate more convenient.
Described outer sleeve 2 tops arrange through type forced filling oil cup 4.Lubricating oil can inject in the place at the through type forced filling oil cup, reduces the friction between the movement parts.
The utility model is put the utility model on the ground first in use.When rotating crank 6, leading screw 3 is rotated, drive screw 7 and whole inner sleeve 1 and do straight-line motion because the base of inner sleeve 1 places ground, thus inner sleeve 1 position maintain static, so so that outer sleeve 2 begin to do relative motion.The utility model links together by bolt and irrigation sprinkler, promotes the irrigation sprinkler chassis so just can reach, and makes things convenient for the transportation of irrigation sprinkler and fixing.
