Detailed description of the invention
With detailed description of the invention, this utility model is further described below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of compensation paper lowering or hoisting gear, including being arranged on the base 1 of ground, being arranged on the hoistable platform 2 of rectangle above base.Lifting for the ease of hoistable platform, we can be respectively provided with fairlead group 3 straight down at four edges at hoistable platform, fairlead group include some fairleads 31 connected together coaxially and be plugged on inner side fairlead in guide post 32, outermost fairlead lower end and the fixing connection of base, the upper end of guide post is then connected with hoistable platform.So, when hoistable platform oscilaltion, fairlead group along with the lifting automatic telescopic of hoistable platform, thus can provide for hoistable platform and lift guiding reliably, improves the hoistable platform stability when lifting.
In addition, as shown in Figure 2 and Figure 3, we can be respectively provided with the lower bearing ring 33 that side extends radially outward in the lower end of fairlead and guide post, the upper shaft carrier ring 34 that side extends radially inward is set in fairlead upper end simultaneously, the lower bearing ring of guide post lower end fits in the fairlead of adjacent inner side, and first from the inside to the outside to the lower bearing ring of the 3rd fairlead lower end fits in second to the 4th fairlead that outside is adjacent respectively, the lower bearing ring of outermost fairlead lower end is then connected by bolt with base plate；Guide post fits in the upper shaft carrier ring of the adjacent fairlead upper end of inner side, and first from the inside to the outside to the 3rd fairlead fits in the upper shaft carrier ring of second to the 4th adjacent fairlead upper end of outside respectively.So, when hoistable platform rises, fairlead group can extend automatically along with hoistable platform, guide post and first to the 3rd fairlead from the inside to the outside rely on the upper shaft carrier ring of adjacent first to fourth the fairlead upper end of the lower bearing ring of lower end and outside to constitute the support guide at upper and lower two ends respectively, thus are conducive to improving the rigidity of fairlead group.Meanwhile, when the fairlead of guide post and inner side protrudes upward, it is spacing that the upper shaft carrier ring of the fairlead upper end that lower bearing ring is adjacent with outside may make up on axially, it is to avoid skidding off of guide post and fairlead.It should be noted that in order to make hoistable platform have enough lifting travels, in order to place the paper of enough height on hoistable platform, as it is shown in figure 1, this utility model is when mounted, at one melt pit of ground excavation, and base can be fixed in melt pit.
Additionally, we also can arrange spacing ring 35 in the centre position on fairlead medial wall is axial, so that the fairlead adjacent to inner side and guide post constitute axial spacing, avoid reducing rigidity and the bending strength of fairlead group because of guide post and excessively stretching out of fairlead, it is ensured that the steady lifting of hoistable platform.Further, we can be oppositely disposed 2 T-shaped regulating tanks 311 axially extended on fairlead sidewall, regulation screw 36 is set in T-shaped regulating tank, regulation screw is threadeded with spacing ring from outside to inside after T-shaped regulating tank, the head of screw of regulation screw is spacing in T-shaped regulating tank, to avoid the fairlead with outside to produce interference.So, we can be according to the different adjustment spacing ring of the weight of paper on hoistable platform and height position in fairlead, while guaranteeing that fairlead group has enough strokes, improves rigidity and the bending strength of fairlead group as far as possible.
We need to arrange support groups of springs 4 between hoistable platform and base, to support hoistable platform.Support groups of springs and include a main support spring 41 being positioned vertically within hoistable platform center and some secondary support springs 42 around main support layout of spring, preferably, the secondary spring that supports is 6, and 6 secondary springs that support circularize equidistantly distribution around main support spring, thus hoistable platform can be produced uniform thrust.In order to avoid supporting the bending of groups of springs, we can be respectively provided with spring guide 43 in main support spring, secondary support spring, the upper end of spring guide arranges discoidal position-arresting disk 44, base is respectively provided with pilot hole 11 at corresponding each spring guide, and the lower end of spring guide fits in the pilot hole of correspondence.Main support spring and the secondary lower end of spring that supports are against base, and upper end is against position-arresting disk.When needing cut paper, paper stack fork truck can be first deposited on hoistable platform by we, and paper now has specified maximum weight, compresses after supporting groups of springs pressurized.We can support the parameter such as the coefficient of elasticity of groups of springs and the weight of hoistable platform by reasonable design, make hoistable platform when placing the paper of rated weight, the upper surface of its paper maintains an equal level with cut paper platform, consequently facilitating the carrying of operator, reduces the working strength of operator.It is to say, the initial elastic force of support groups of springs now is equal with the load that hoistable platform and paper are constituted.After the Some paper sheets of hoistable platform upper epidermis is removed and cuts, paper height on hoistable platform correspondingly reduces, thus the weight of paper alleviates therewith on hoistable platform, thrust needed for promoting hoistable platform to rise the most correspondingly declines, it is to say, the load that the elastic force now supporting groups of springs is constituted more than hoistable platform and paper, therefore, main support spring, the secondary spring that supports promote hoistable platform automatically to rise by position-arresting disk, thus automatically compensate for the lifting height of hoistable platform.It is understandable that, we can support the coefficient of elasticity of groups of springs by reasonable design, make the coefficient of elasticity supporting groups of springs identical with the paper weight of unit thickness, thus can ensure that the offset of rising automatically of hoistable platform is equal with the falling head of paper, and then guarantee that the paper on hoistable platform keeps contour with cut paper platform all the time.It is understood that, the coefficient of elasticity supporting groups of springs is the ratio supporting elastic force produced by groups of springs pressurized with decrement, such as, the paper weight of the coefficient of elasticity and unit thickness that support groups of springs is 5kg/cm, that is, supporting groups of springs often compress or extend one centimetre, the elastic force of its correspondence is i.e. increased or decreased 5 kilograms, and the paper weight of a cm thick is also 5 kilograms.So, when the paper sheet thickness on hoistable platform declines 5 centimetres, the weight of its correspondence declines 25 kilograms, correspondingly, supporting groups of springs and then protrude upward 5 centimetres, the elastic force supporting groups of springs reduces 25 kilograms the most accordingly, flushes so that making the height of paper remain with cut paper platform, operator can remain that the paper on hoistable platform can be transported on cut paper platform by standing state easily, thus significantly increases the efficiency of cut paper.It is to say, no matter the paper height on hoistable platform reduces how many, hoistable platform can rise compensation the most automatically.When hoistable platform oscilaltion, slide in the pilot hole of base in the lower end of spring guide, is effectively prevented from main support spring and the secondary spring that supports bends.
Coefficient of elasticity due to whole support groups of springs is equal to the coefficient of elasticity sum of the spring all worked, therefore, in order to adapt to cutting of the paper of different size type, we can arrange corresponding guide post lockable mechanism on base, so that guide post respect thereto keeps fixing, and then make main support spring that this spring guide is corresponding or the secondary spring that supports the most no longer extend and inoperative, to select to support the different coefficient of elasticity of groups of springs, it is achieved with mating of the paper of different size type.Meanwhile, we can hang the balancing weight 21 of similar counterweight respectively in the centre position of 4 sides of hoistable platform lower surface, and by selecting the balancing weight of approrpiate wts, the elemental height making hoistable platform is contour with the cut paper platform of paper cutter.For the ease of adjusting the coefficient of elasticity supporting groups of springs, we can make 6 secondary support in springs positioned opposite first identical with the coefficient of elasticity of the 4th secondary support spring, second is identical with the coefficient of elasticity of the 5th secondary support spring, 3rd is identical with the coefficient of elasticity of the 6th secondary support spring, thus formed by the first first secondary support spring pair constituted with the 4th secondary support spring, second and the 5th secondary support that spring constitutes second is secondary supports spring pair, 3rd and the 6th secondary the 3rd the secondary support spring pair supporting spring composition, that is, 6 secondary spring formation 3 pairs altogether that support support spring pair.We set the coefficient of elasticity of main support spring as k, first secondary coefficient of elasticity supporting spring is k1, second secondary coefficient of elasticity supporting spring is k2,3rd the secondary coefficient of elasticity supporting spring is k3, and k: k1: k2: k3=1: 0.05: 0.1: 0.15, so, 3 secondary coefficient of elasticity supporting spring pair are respectively 2k1,2k2,2k3, therefore, the coefficient of elasticity of main support spring is 1: 0.1: 0.2: 0.3 with the ratio of first, second, third secondary coefficient of elasticity supporting spring pair.So, we can be according to the coefficient of elasticity correspondingly arranging main support spring on the basis of the lightest specification type of unit thickness weight in the paper that need to cut.When we by corresponding guide post lockable mechanism by 3 secondary springs that support to when doing the locking of multi-form, main support spring i.e. may make up different combinations with 3 secondary support springs, and then makes whole support groups of springs have different coefficient of elasticity.Such as, when our lockings 3 are secondary support spring pair time, only in the middle of main support spring work, its coefficient of elasticity is k, it is adaptable to the paper that the paper weight of unit thickness is the lightest；When our second, third secondary support spring pair of locking, main support spring and first secondary spring that supports are to working, and its coefficient of elasticity is coefficient of elasticity coefficient of elasticity sum 1.1k with first secondary support spring pair of main support spring；In like manner, main support spring and second or the 3rd the secondary spring that supports coefficient of elasticity during combination is respectively 1.2k, 1.3k.When we by main support spring and first and the 3rd secondary support spring to combination time, its coefficient of elasticity is 1.4k；In like manner, when we by main support spring and second and the 3rd secondary support spring to combination time, its coefficient of elasticity is 1.5k；When main support spring and 3 pairs are supported spring to combination by us, its coefficient of elasticity is 1.6k.That is, support groups of springs can combination in any and form the coefficient of elasticity of linear increment, thus adapt to the paper of different specification types, and guarantee the matching degree supporting between coefficient of elasticity and the paper weight of unit thickness of groups of springs, and then make the paper height on hoistable platform remain basically identical with cut paper platform.Particularly, by the main support spring at hoistable platform center or by main support spring and be symmetrically dispersed in main support spring both sides secondary and support the support groups of springs of spring assembly hoistable platform is had stable motive force, thus the lifting of beneficially hoistable platform.
Guide post lockable mechanism of the present utility model includes being arranged on the lock sleeve 5 at base upper surface correspondence spring guide, and the lower end of spring guide fits in the lock sleeve of correspondence, and main support spring now, the secondary lower end of spring that supports are against lock sleeve upper surface.As shown in Figure 4, lock sleeve sidewall arranging locking screw radially, locking screw female thread connects lock bolt 6.When we lock lock bolt, spring guide can by the most locked at an arbitrary position.It addition, we also can arrange the lock groove 431 of some cones being equally spaced vertically on the lateral surface of spring guide, lock bolt is cone near the tail end of spring guide, and the tapering of lock bolt tail end is adaptive with the tapering of lock groove.During as such, it is desirable to cut paper, we can show the weight according to unit thickness paper and calculate the coefficient of elasticity that support groups of springs is corresponding, and the briquetting being then used for debugging by is placed into hoistable platform, makes hoistable platform be on minimum starting altitude.Then we lock corresponding lock bolt according to aforesaid calculating, now the conical tail end of lock bolt gets final product screens in the lock groove of spring guide, so that it is guaranteed that the locking of spring guide, so that the coefficient of elasticity of the paper coupling making whole support groups of springs have and need to cut, thus complete the debugging supporting groups of springs coefficient of elasticity.Now removing briquetting, hoistable platform rises to flush with cut paper platform, and the paper that needs cut can be placed on hoistable platform by we, and hoistable platform i.e. declines the height identical with paper sheet thickness, makes the paper on hoistable platform keep highly consistent with cut paper platform.It is to say, the change of the paper initial thickness placed on hoistable platform of the present utility model will not produce impact to effect.If it is understood that have difference in height between hoistable platform and cut paper platform now, we can correspondingly adjust the weight of balancing weight, to guarantee to keep contour between hoistable platform and cut paper platform.
