Abstract
The utility model belongs to excavation machinery technical field, disclose a kind of lifting table for keeping in repair digger revolving supporting, be arranged on the below of excavating machine upper body counterweight part, key is: described lifting table comprises base, the guide pillar be fixedly installed on described base, be sleeved on sliding sleeve on guide pillar and the brace table fixing with sliding sleeve, has perpendicular straight elevator degree of freedom by lifting drive, described brace table along guide pillar.Adopt the face supporting way of rigid contact, car body is steady, and lifting table floor area is little, easy to use, quick, expense is low.
Description
Technical field
The utility model belongs to excavation machinery technical field, relates to the tooling device of excavation machinery installation and maintenance, specifically a kind of lifting table for keeping in repair digger revolving supporting.
Background technology
Pivoting support is the vitals of excavating machine, and because of the work under bad environment of excavating machine, digger revolving supporting runs under large load of being everlasting, large impact situation, very easily weares and teares, and needs often to change and maintenance.
When keeping in repair pivoting support and change, need the upper body of excavating machine to support, conventional method has two kinds, and a kind of is lift with the upper body of hoisting crane by excavating machine, and another kind utilizes jack by upper body jack-up.Utilize hoisting crane to hang and go up car body, need allotment, employ hoisting crane, keep in repair long in time limit, use cost is high, and hoisting crane floor area is large, and each dismounting upper body needs reserved larger space, and lifting car body is also not too steady, and potential safety hazard is large.Adopt jack by the mode of upper body jack-up, although convenient and swift, jack is support, and car body is steady, particularly by the lower seam of turn table with the outer race of pivoting support to timing, because of needs torsion, easily topple over, potential safety hazard is large.
Summary of the invention
The utility model in order to solve maintenance digger revolving supporting time, support upper body cause long in time limit, costly, the jiggly problem of car body, devise a kind of lifting table; Adopt the face supporting way of rigid contact, car body is steady, and lifting table floor area is little, easy to use, quick, expense is low.
The technical solution of the utility model is: a kind of lifting table for keeping in repair digger revolving supporting, be arranged on the below of excavating machine upper body counterweight part, key is: described lifting table comprises base, the guide pillar be fixedly installed on described base, be sleeved on sliding sleeve on guide pillar and the brace table fixing with sliding sleeve, has perpendicular straight elevator degree of freedom by lifting drive, described brace table along guide pillar.
Further, brace table comprises the top board, base plate and the muscle floor that is welded between top board and base plate that weld with sliding sleeve integral type.
Further, muscle floor comprises " ten " glyph framework and is arranged on the waveform riser outside " ten " glyph framework.
Further, lifting drive is arranged on the jack between base and brace table base plate.
Further, reinforced rib is welded with between the top board of sliding sleeve outer wall and brace table, base plate.
Further, guide pillar is 4-8 root, is distributed on base, and jack is arranged on guide pillar group switching centre.
The beneficial effects of the utility model are: 1, the utility model and support excavating machine upper body front portion jack with the use of, for supporting excavating machine upper body rear portion, by the jack be arranged between base and brace table, brace table with support the jack of excavating machine upper body front portion and coordinate and to hold in the palm liter and to prop up excavating machine upper body; Adopt the face supporting way of rigid contact, car body is steady, and safety is high.2, lifting table floor area is little, is easy to carry about with one, for the excavating machine of field work, maintenance and change pivoting support convenient, fast, expense is low.3, lifting drive adopts jack, is easy to carry about with one, and adapts to the muscle floor that jack stroke arranges framed structure, can meet rigidity requirement, and weight is also comparatively light, carries, easy to use.4, between sliding sleeve outer wall and brace table, arrange brace rod, and jack is arranged on guide pillar group switching centre, stability is high.5, this lifting table can utilize discard to make, with jack with the use of, cost is low.
Accompanying drawing explanation
Fig. 1 is perspective view of the present utility model;
Fig. 2 is the structural representation from the A of Fig. 1 to cutting brace table;
In accompanying drawing, 1 is base, and 1-1 is guide pillar, and 2-1 is top board, and 2-2 is base plate, and 2-3 is muscle floor, and 3 represent sliding sleeve, and 4 represent reinforced rib, and 5 is jacks.
Detailed description of the invention
A kind of lifting table for keeping in repair digger revolving supporting, be arranged on the below of excavating machine upper body counterweight part, key is: described lifting table comprises base 1, the guide pillar 1-1 be fixedly installed on described base 1, be sleeved on sliding sleeve 3 on guide pillar 1-1 and the brace table fixing with sliding sleeve 3, has perpendicular straight elevator degree of freedom by lifting drive, described brace table along guide pillar 1-1.
Brace table comprises the top board 2-1 welded with sliding sleeve 3 integral type and the muscle floor 2-3 be welded between top board 2-1 and base plate 2-2.Muscle floor 2-3 is made up of " ten " glyph framework and the waveform riser be arranged on outside " ten " glyph framework, and waveform riser is chopping sea or trapezoidal wave.Lifting drive is arranged on the jack 5 between base 1 and brace table base plate 2-2.Adopt jack 5 as lifting drive, easy to use, be easy to carry about with one, but because of jack stroke limited, brace table top board 2-1 with weld muscle floor 2-3 between base plate 2-2 to adapt to the height of jack 5.Muscle floor 2-3 adopts framed structure, middle " ten " shape framework for welding, framework surrounding welding waveform riser, the two ends up and down of waveform riser are welded on top board 2-1 and base plate 2-2 respectively, such setting not only can ensure support stiffness, can also expendable weight.
In order to strengthen the stability of lifting table, weld reinforced rib 4 at sliding sleeve 3 outer wall and brace table between top board 2-1, base plate 2-2, and guide pillar 1-1 is set to 4-8 root, is distributed on base 1, jack 5 is placed on guide pillar group switching centre.Guide pillar 1-1 is hollow tubular, welds with base 1 integral type.
During concrete enforcement, see Fig. 1, Fig. 2, because counter weight of excavator focuses mostly at upper body rear portion, so during maintain and replace pivoting support, ensure the stable support at upper body rear portion most important.When utilizing this lifting table to keep in repair, support lighter excavating machine upper body with two jacks anterior, lifting table supports excavating machine upper body rear portion, between its base 1 and brace table base plate 2-2, place jack 5, by these three jacks, brace table can hold in the palm and rises and prop up excavating machine upper body.
