Description

Lift construction costs workbench

Technical field

The utility model is related to Project Cost Field, more particularly to a kind of lift construction costs workbench.

Background technology

Construction costs refers to carry out the full payment that a certain engineering construction is spent, and its core content is investment estimate, set Count budgetary estimate, amendment budgetary estimate, working drawing budget, Engineering Settlement, budget needed for the completion of projects etc., staff need according to drawing, quota and Bill code, calculates flat cost, enterprise administration expense, measure expense, set-fee, profit and tax included in engineering etc..

When staff carries out the operation such as construction costs, workbench will necessarily be used, drawing mapping is carried out or items is taken Calculating, because the height of every staff is not quite similar, use habit is also different, therefore the workbench meeting of uniform height Make part staff do not feel like oneself to answer, so as to influence operating efficiency, or even the healthy of staff can be damaged.

Utility model content

The purpose of this utility model is to provide a kind of lift construction costs workbench, and it has can be by according to work The advantage of the different adjustment height of personnel.

Above-mentioned technical purpose of the present utility model technical scheme is that：

A kind of lift construction costs workbench, including base, table top and the fixation for connect base and table top Post, the fixed column includes the sleeve being fixed on base and the inner prop being fixed on table top, and inner prop is set in sleeve, inner prop One end in sleeve, which is provided with correspondence position on snap ring, sleeve and is provided with, to be used in the spacing ring for snap ring defined position, sleeve It is additionally provided with for driving inner prop to slide up and down the drive mechanism of motion.

It is arranged such, inner prop is fixed on table top, sleeve is fixed on base, drive device drives inner prop sliding in sleeve It can just drive table top to lift during shifting, make it closer or far from base, reach the purpose for changing height of table, snap ring and spacing Using cooperatively for ring can limit the distance that inner prop slides in sleeve, prevent inner prop skidding distance excessive and taken off from sleeve Fall, while the stability that inner prop slides in sleeve can be ensured, make the lifting process of whole workbench more steady, so that side Just workbench is adjusted to each adaptive height by staff, improves operating efficiency.

Further set：The drive mechanism includes motor, active worm screw, driven worm gear and driven leading screw, actively Worm screw is fixedly connected with the output shaft of motor, and driven worm gear is set in driven leading screw and is connected with driven threads of lead screw.

It is arranged such, motor drives the rotation of active worm screw, then driven worm gear also and then rotates, due to driven worm gear phase It is fixed to height, and driven worm gear is connected through a screw thread with driven leading screw, after driven worm gear rotation, in the effect of screw thread Under, leading screw produces the motion risen or fallen, and this makes it possible to drive, inner prop and table top are up and down, reaches the whole work of change The purpose of the height of platform.

Further set：The inner prop is provided with bottom plate towards sleeve one end, and driven leading screw is arranged with rolling towards inner prop side Dynamic bearing, rolling bearing is embedded on bottom plate.

It is arranged such, because the up and down motion of leading screw is completed by rotating, so if leading screw is directly fixed Bottom plate and inner prop can be made on bottom plate as leading screw rotates, in the setting of rolling bearing can make not drive during leading screw rotation and lifting Post and table top are rotated, and can be reduced condition required during worktable lifting, be reached more preferable using effect.

Further set：The sleeve intermediate altitude is provided with positioning table, and motor is fixed in positioning table.

It is arranged such, due to needing certain height when being slid above and below leading screw, motor is fixed on intermediate altitude It can allow leading screw that there is enough height to be lifted in positioning table, while motor is centrally located can to make leading screw There is more preferable stability when rising or falling, more preferable using effect is reached with this.

Further set：The drive mechanism includes being fixed on interior column bottom and vertically disposed push rod, several rings The drive cylinder set around push rod, output shaft and the push rod of drive cylinder are fixed by horizontally disposed support plate.

It is arranged such, the output shaft of drive cylinder can drive support plate to move up and down, so that push rod is up and down, pulls Slid above and below the table top of workbench, reach the purpose of self-powered platform, and be directly driven and can make using drive cylinder The distance of driving is equal with the elongated distance of output shaft, the height of table top lifting relatively easy to control.

Further set：The support plate end is provided with stage clip, stage clip connect base and support plate.

It is arranged such, because the quality of table top and inner prop is larger, directly uses drive cylinder as support there is a possibility that whole Individual workbench is unstable, and the setting process auxiliary drive cylinder of stage clip disperses the quality of table top and inner prop, keeps the steady of whole workbench It is qualitative, reach more preferable support effect.

Further set：The quantity of the drive cylinder is 3~4.

It is arranged such, the quantity of drive cylinder can make panel and inner prop when being less than three easily generation is rocked, due to triangle Shape is most stable of structure, sets the drive cylinder of more than three and table top can be made to keep good stability in rising, and Drive cylinder cost more than 4 is higher, thus drive cylinder quantity be arranged on 3~4 it is more suitable.

Further set：The drive mechanism include some support bars and hydraulic cylinder, support bar one end with it is interior column articulated, The other end is slidably connected on base, and output shaft and the support bar of hydraulic cylinder are hinged close to base one end.

It is arranged such, output shaft driving support bar one end of hydraulic cylinder slides on base, and the other end of support bar exists Rotated on inner prop, can thus change the angle of support bar, so as to change the bearing height of support bar, reach lifting inner prop and The purpose of table top.

Further set：The base is provided with chute, and support bar is provided with roller, and roller is placed in chute.

It is arranged such, chute can limit the sliding trace of support bar, prevents support bar from being slid under the driving of hydraulic cylinder Arrive elsewhere, so as to ensure the stability of strutting system of support bar, the glide direction for the support bar that the setting of roller is further limited, Make slip more smooth.

Preferably, the sleeve is square, chute is extended by four angular centers of sleeve, chute and support bar Quantity be 4.

It is arranged such, support bar slides from four angular middle slips, four angles and promote inner prop and table top liter together Drop, stability when lifting table top is more good, so as to reach more preferable using effect.

In summary, the utility model has the advantages that：

The stability that drive mechanism driving inner prop slides in sleeve preferably, more put down by the lifting process of whole workbench Surely, so as to facilitate staff that workbench is adjusted into each adaptive height, operating efficiency is improved, stationary work-table is reduced high Spend the damage for staff's health.
