Description

A kind of rolling stand

Technical field

The utility model relates to device for transporting objects, relates in particular to a kind of rolling stand.

Background technology

The key of Detroit automation is each conveying process in the industrial process, has only high efficiency, delivery system safe, easy to maintenance to provide the failure-free guarantee for Detroit automation, could improve enterprises production efficiency.In the middle of the manufacturing enterprise of large product, the feedway of delivery system be power operation partly usefulness be the structural pattern that base adds cylinder, existing rolling stand structural representation as shown in Figure 1, a base that supports and play the resting barrel effect has determined the operation height of rolling stand, if adjust the height of manufacturing line, must be from changing base, this certainly will increase enterprise's productive costs; Except cylinder is movably connected in the general all mode captive joints to weld of other parts on the base by rotating shaft, though manufacturing cost has reduced, but increased use cost, in case having to damage, rolling stand causes dismantling the manufacturing cost that maintenance cost is higher than rolling stand, so existing rolling stand function singleness is keeped in repair complicated cost height.

The utility model content

The technical problems to be solved in the utility model provides a kind of rolling stand, and the operation height of rolling stand can free adjustment and assembled by separating component.

For solving the problems of the technologies described above, the utility model adopts following technical proposals: rolling stand comprises cylinder, described cylinder is installed on the telescopic pedestal, described pedestal comprises base, support, attaching parts, described cylinder is movably connected on the support by rotating shaft, be movably connected by attaching parts between described support and the base, described attaching parts is made up of two staggered form pivotally attached connecting rods, described base is provided with slideway I, described support is provided with slideway II, wherein connecting rod two ends of described attaching parts are separately positioned on slideway I and the slideway II, and the end that described connecting rod is positioned at slideway I is fixed on the base by adjustable slide-bar.

As a kind of improvement of the present utility model, described base also is provided with stationkeeping and screw mandrel free to rotate, described screw mandrel one end passes slide-bar and flexibly connects with slide-bar, the other end extends to base exterior, described base bottom is provided with the shirt rim, described shirt rim is provided with the perforate that is used for fixing, and the end that described screw mandrel extends to base exterior is fixed with manual unit.Screw body becomes simple with the adjustment process of attaching parts.

As of the present utility model a kind of preferred, described manual unit is a handwheel.The handwheel volume is small and exquisite, and it is bigger to be suitable for palm, and hand strength strong people use.

Preferred as another kind of the present utility model, described manual unit is folding crank.Collapsible crank can form the very long arm of force after launching, and therefore only needs the very little power just can rotary screw rod and then adjust roller height, helps the little people's use of those hand strength.

As another kind of improvement the of the present utility model, described rotating shaft is with spring between support and cylinder.Spring can make reset roller when cylinder produces out-of-position, avoid producing between cylinder and the support friction.

The utility model adopts technique scheme, and the operation height of rolling stand can free adjustment, satisfies the needs of different production status; Adopt separating component part replacement easy to assembly simultaneously, reduced use cost, make that the fast parts of some consumes can be upgraded in time, thereby avoid scrapping whole rolling stand; Manual unit adopts multiple lever, can tackle the use habit of different people; Cylinder is energy automatically regulating control position when work, and the friction of minimizing and support has prolonged service life.

The specific embodiment

As shown in Figure 6, base 2, support 3, attaching parts 4 and the cylinder 1 of comprising of the present utility model, shown in Fig. 2,4,5, support 3 is the rectangular slab of perforate 12 in the middle of, cylinder 1 is installed on the support 3 by rotating shaft 5, and rotating shaft 5 is prolonged length of side direction and crossed entire bracket 3; And be with a spring 15 in the rotating shaft 5 between cylinder 1 and the support 3, spring 15 is pressed to put between cylinder 1 and support 3, each spring 15 of cylinder 1 the right and left, so cylinder 1 is clamped down on centre at support 3 by spring 15.Base 2 bottoms of rolling stand are provided with shirt rim 11, and the profile of shirt rim 11 is rectangle and is provided with four perforates 12 that are used for fixing base 2.Shown in Fig. 2,3,4,6, support 3 is movably connected by attaching parts 4 and base 2, be provided with two attaching partss 4 at support 3 and base 2, attaching parts 4 is made up of by the screw staggered form is hinged in the middle of separately two connecting rods 6, therefore four connecting rods 6 are arranged, the two ends of every connecting rod 6 all are movably connected in respectively on support 3 and the base 2 by screw and nut.Shown in Fig. 2,6, on base 2, be provided with slideway I7, support 3 is provided with slideway II8, slideway I7, slideway II8 become to be horizontally disposed with, wherein connecting rod 6 two ends of attaching parts 4 are separately positioned on slideway I7 and the slideway II8, and the end that connecting rod 6 is positioned at slideway I7 is fixed on the base 2 by adjustable slide-bar 9.As shown in Figure 8, base 2 is provided with a stationkeeping but the screw mandrel 10 that can freely rotate, screw mandrel 10 is fixed the seat on base 2 by two mounting rings 16, because do not clamp with base 2 between the mounting ring 16, still can freely rotate so screw mandrel 10 positions are fixed; Screw mandrel 10 threaded ends pass slide-bar 9 and flexibly connect with slide-bar 9.Screw mandrel 10 extends base 2 exterior ends and is fixed with manual unit, and the manual unit in first kind of embodiment of the utility model adopts handwheel 13.

When rolling stand is in folded state, two attaching parts 4 levels are diverged to angle and are in minimum rating, support 3, attaching parts 4, base 2 all close up together, screw in the slideway slideway I7 is at the high order end of slideway I7 at this moment, and the screw in the slideway II8 is at the low order end of slideway II8, because slideway I7 by screw retention on slide-bar 9, so slide-bar 9 also is in the high order end of slideway I7.Drive screw mandrel 10 rotations when rotating handwheel 13, make slide-bar 9 move by the cooperation between screw thread to the right-hand member of slideway I7, screw in the slideway II8 is moved to the left end simultaneously, the level of attaching parts 4 is diverged to when angle slowly increases low order end that screw in slideway I7 is in slideway I7, high order end that the screw in the slideway II8 is in slideway II8 and is stopped to increase, this moment, support 3 was lifted, the operation height of cylinder 1 is in high state, and the utility model can free adjustment and can be stabilized under this state in scope below the high state.So the operation height of the utility model rolling stand can be regulated.Again because be with spring 15 in the rotating shaft 5 at cylinder 1 two ends, so when work, do not have friction between cylinder 1 and the support 3, under the situation of its offset, can carry out resetting of cylinder 1, make rolling stand have longer service life by resetting of spring 15.

Use because the size of staff, the factors of having an effect such as custom, handwheel 13 adapt to the people that palm is big, hand strength is strong most, can save the space for whole rolling stand, make its structure comparatively simple with handwheel 13; And rotate handwheel 13 for the little people of strength are things that part is required great effort very much, as shown in Figure 7, second kind of embodiment of the present utility model adopts folding crank 14, spread Shi Qineng out when crank 14 and under less action force, produce bigger moment, rotate thereby the less people of hand strength just can start screw mandrel 10 by crank.
