Abstract
A combined lifting mechanism comprises a shear fork lifting mechanism body and a lead screw lifting mechanism body. In the shear fork lifting mechanism body, roller wheels are installed on a force transfer base, one end of each shear fork arm assembly is connected with a lead screw installed on the force transfer base, the other end of each shear fork arm assembly is connected with a lifting table, and a rotating rocker arm is installed on one side of the force transfer base and connected with the lead screw. In the lead screw lifting mechanism body, a trapezoidal lead screw penetrates through the lifting table and is hinged to the lead screw, and a hand wheel is installed on the trapezoidal lead screw. The initial installation height of the lead screw lifting mechanism body is increased through the shear fork lifting mechanism body, equipment can be lifted in a narrow space, the combined lifting mechanism is convenient and fast to use, and the maintaining efficiency of an airplane can be improved substantially. Furthermore, the force transfer base is provided with guide grooves, sleeves roll in the guide grooves of the force transfer base through bearings arranged at the two ends of each sleeve, in this way, the angle between square-tube shear fork arms is changed, ascending or descending of the lifting table is achieved, and the two lifting mechanism bodies do not depend on each other during ascending and descending; besides, the combined lifting mechanism is simple in structure and convenient and fast to use; meanwhile, as the roller wheels are arranged on the force transfer base, working efficiency can be effectively improved.
Description
Technical field
The present invention relates to mechanical lifting gear technical field, particularly relate to a kind of combination lifting mechanism.
Background technology
In aircraft utilization handling labor, often to need under ventral loader-unloader in small space to carry equipment, and for the larger equipment of quality, be difficult to handling labor, usually needed by lifting mechanism, equipment larger for quality to be held up.At present conventional two kinds single lifting mechanisms: one is screw lift structure, has structure simple, can in small space the feature of lifting equipment, but lifting travel is by the restriction of installing elemental height; Two is scissor-type lifting mechanisms, but structure takes up room comparatively large, and use operation has certain limitation, is difficult to the installation requirements meeting small space.
Summary of the invention
Technical matters solved by the invention is to provide a kind of combination lifting mechanism, to solve the shortcoming in above-mentioned background technology.
Technical matters solved by the invention realizes by the following technical solutions:
A kind of combination lifting mechanism, comprises scissors fork elevating mechanism, screw lift structure; Wherein, in scissors fork elevating mechanism, roller is arranged on power transmission base, and scissor arm component one end is connected with the screw mandrel be arranged on power transmission base, and the other end is connected with bay-lift, rotates rocking arm and is arranged on power transmission base side, and be connected with screw mandrel; In screw lift structure, trapezoidal screw through bay-lift and screw mandrel hinged, handwheel is arranged on trapezoidal screw, by scissors fork elevating mechanism with the installation elemental height of enhancing screw lifting mechanism, can in small space lifting equipment, easy to use, the maintenance efficiency of aircraft can be increased substantially; In addition, power transmission base is provided with guide groove.
In the present invention, scissor arm component comprises a prescription pipe scissor arm, and is bolted between square tube scissor arm, has the advantage of stabilized structure, reliable, safe and efficient, failure rate is low; Simultaneously annex installing space size Selection square tube scissor brachium can be become short or adopt two-stage scissor with aircraft according to lifting travel.
In the present invention, screw mandrel is set with sleeve, sleeve embeds in the guide groove of power transmission base by the bearing that two ends are arranged, the screw mandrel on power transmission base is driven to rotate by rotating rocking arm, sleeve bearings at both ends is rolled in guide groove, thus the angle changed between square tube scissor arm realizes rise or the reduction of bay-lift.
In the present invention, power transmission base is provided with reinforced rib, is conducive to the stability of power transmission base.
In the present invention, trapezoidal screw is at right angle setting, takies volume little, can according to rest object and installing space size design pallet size thereof; Simultaneously the Design of length of trapezoidal screw will meet two aspects and requires: one is scissors fork elevating mechanism when dropping to minimum, can not contact to earth in trapezoidal screw bottom; Two is scissors fork elevating mechanism and screw lift structure two-stage lifting mechanism when all dropping to minimum, under installation car can enter into ventral.
In the present invention, roller is arranged on the bearing of power transmission base extension setting.
Beneficial effect: the present invention is combined by scissors fork elevating mechanism and screw lift structure, the bearing that sleeve is arranged by two ends rolls in the guide groove of power transmission base, thus the angle changed between square tube scissor arm realizes rise or the reduction of bay-lift, do not rely on mutually during the lifting of two-stage lifting mechanism; And structure is simple, easy to use, the maintenance efficiency of aircraft can be increased substantially; On power transmission base, be provided with roller simultaneously, effectively improve work efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of preferred embodiment of the present invention.
Detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
See the one combination lifting mechanism of Fig. 1, comprise scissors fork elevating mechanism 10, rotate rocking arm 11, screw mandrel 12, square tube scissor arm component 13, bolt 14, bay-lift 15, power transmission base 16, roller 17, screw lift structure 20, handwheel 21 and trapezoidal screw 22.
In scissors fork elevating mechanism 10, roller 17 is arranged on power transmission base 16, square tube scissor arm component 13 one end is connected with the screw mandrel 12 be arranged on power transmission base 16, the other end is connected with bay-lift 15, square tube scissor arm in square tube scissor arm component 13 is connected by bolt 14, rotate rocking arm 11 and be arranged on power transmission base 16 side, and be connected with screw mandrel 12; In real work, annex installing space size can be become to carry out appropriate design square tube scissor brachium with aircraft according to lifting travel short or adopt two-stage scissor, the screw mandrel 12 on power transmission base 16 is driven to rotate by rotating rocking arm 11, screw mandrel 12 is set with sleeve, sleeve bearings at both ends is rolled in the guide groove of power transmission base 16, thus between change scissor arm, angle realizes rise or the reduction of bay-lift 15.
In screw lift structure 20, trapezoidal screw 22 is hinged through bay-lift 15 and screw mandrel 12, handwheel 21 is arranged on trapezoidal screw 22, by the installation elemental height of scissors fork elevating mechanism 10 enhancing screw lifting mechanism 20, can in small space lifting equipment, easy to use, the maintenance efficiency of aircraft can be increased substantially.
In the present embodiment, trapezoidal screw 22 at right angle setting, its Design of length will meet two aspects and require: one is scissors fork elevating mechanism 10 when dropping to minimum, can not contact to earth in trapezoidal screw 22 bottom; Two is scissors fork elevating mechanisms 10 when all dropping to minimum with screw lift structure 20 two-stage lifting mechanism, under installation car can enter into ventral; By rotation hand wheel 21, trapezoidal screw 22 moved up and down thus drive pallet to rise or reduce, because trapezoidal screw 22 is at right angle setting, taking volume little, pallet size can be designed according to rest object and installing space size thereof simultaneously.
