The specific embodiment
For further understanding content of the present utility model, feature and effect, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
As shown in Figure 1, the present embodiment discloses a kind of rotatable Portable lifting machine, mainly by base 1, support 2, swivel mount 3, winch 4, fixed pulley 6 and link up with 7 and form.On base 1, be fixedly connected with support 2, be set with swivel mount 3 on support 2, winchs 4 are installed in swivel mount 3 one end, and the other end is installed fixed pulley 6, the chute of the coiling rope 5 of winch 4 by fixed pulley 6 with link up with 7 and be connected, and hang and connect weight.
As shown in Figure 2, base 1 is being welded into compared with short bottom plate 11 with compared with elongated base plate 12 of being made by 10# channel-section steel " T " character form structure, compared with one end of elongated base plate 12, be welded in compared with the midway location of short bottom plate 11.Shown in Fig. 5, base 1 compared with elongated base plate 12 with compared with the Length Ratio of short bottom plate 11, be at least 2:1, i.e. L
1: L
2>2:1, enough to support above whole lifting machinery.Base 1 is positioned ground at a, b, c, tetra-attachment points of d.
As shown in Figure 3, support 2 comprises main support rod 21, auxiliary support bar 22, equalizing supporting rod 23, and main support rod 21 preferably adopts the steel pipe manufacturing of DN40.The both sides of main support rod 21 bottoms are welded with respectively an auxiliary support bar 22, the bottom welding of auxiliary support bar 22 in base 1 compared with the two ends of short bottom plate 11, auxiliary support bar 22 can utilize band iron, pound the flat making such as steel scrap pipe.By mechanical analysis, it is to take into account the stressed optimal solution with pole length of bar that auxiliary support bar 22 and main support rod 21 are 45 ° of angles.Equalizing supporting rod 23 one end are welded in main support rod 21 middle parts, take be positioned at main support rod 21 with the position of intersecting point of sleeve pipe 31 as good, the other end be welded in base 1 compared with outer position, elongated base plate 12 middle parts, take distance compared with elongated base plate 12 outer end 400-500mm as good so that equalizing supporting rod 23 with the acute angle angular range of main support rod 21 within 45 °～90 °.
It is the effect of supporting total and connecting base 1 and swivel mount 3 that main support rod 21 in support 2 mainly plays; Auxiliary support bar 22, for supplemental support, to increase the stressed of support section, can not be offset total; Equalizing supporting rod 23 is mainly used in the center of gravity of balance bracket 2, avoids making support 2 top-heavy and overturning occurs.
As shown in Figure 4, swivel mount 3 comprises sleeve pipe 31, mounting rod 32, diagonal brace 33.The steel pipe of sleeve pipe 31 preferred DN50, its length can be determined according to site operation actual conditions and different operating person s own situation, is generally 1.5m.Sleeve pipe 31 is sleeved on main support rod 21 tops, usings the intersection point of sleeve pipe 31 and mounting rod 32 as the locating point of swivel mount 3 rotations.Suggestion is lubricated at the position apply lubrication oil of sleeve pipe 31 inwalls and support 1 generation friction, thereby can make sleeve pipe 31 rotate smoothly with respect to main support rod 21.The top of sleeve pipe 31 is welded with mounting rod 32, and mounting rod 32 preferably adopts the good steel of compliant material such as solid drawn pipe or reinforced pipe.Mounting rod 32 is tilted to down along the bearing of trend compared with elongated base plate 12 of base 1, the distance h on its least significant end and ground operates winch 4 handle height for staff, the shortest distance of its most significant end and main support rod 21 should meet safety distance requirement, I is more than or equal to 1m.Mounting rod 32 is mainly used in supporting winch 4 and fixed pulley 6 is installed, and is connected with sleeve pipe 31, thereby can rotate up with the sleeve pipe 31 1 360 ° of sides that coexist in use.Between the bottom of the middle part of mounting rod 32 and sleeve pipe 31, be connected with diagonal brace 33, its effect is increase mounting rod 32 stressed, better to support winch 4.Mounting rod 32 most significant ends are to the length between mounting rod 32 and the point of connection of main support rod 21, and mounting rod 32 least significant ends are 1:4～1:5, i.e. L to the length ratio between mounting rod 32 and the point of connection of main support rod 21
3: L
4scope be 1:4～1:5, this proportional range is the ratio with the height of fixed pulley 6 according to height h, by the similar proportion of similar triangle, is drawn.
Mounting rod 32 least significant ends of swivel mount 3 are provided with winch 4, and most significant end is provided with fixed pulley 6, and the coiling rope 5 of winch 4 is connected with hook 7 by the chute of fixed pulley 6.Winch 4 models are KCD type multifunctional motor-driven gig, voltage 220～380V, and hoisting capacity 500Kg, lifting height 1～100m, hoisting speed 7～14m/min, can realize rotating, by erecting frame, is fixed on mounting rod 32; Fixed pulley 6 diameter 100mm; Hook 7 is selected cold rolling round steel to bend and is advisable.The mounting rod 32 of swivel mount 3 needs tooth pad 8 with the flexible direction of guiding coiling rope 5 at α, β place, positioning element 8 can adopt as common parts such as nuts.
Due to swivel mount 3 uniform stresseds, can there is not curved flat phenomenon, therefore can overcome metal tube member suffered gravity when lifting weight, avoid distortion.Swivel mount 3 and the winch 4 being fixed thereon and fixed pulley 6 all can curl up support 1 does 360 ° of rotations, and the Portable lifting machine of the same type with other compared and had more alerting ability, can reduce to a certain extent workmen's labour intensity.In addition, base 1, support 2, swivel mount 3 all can utilize camp site waste and scrap field fabrication, and technique is simple, has considerable economy.
During use, first the rotatable Portable lifting machine of the present embodiment is placed near installation site, will be hung cable, crane span structure etc. and be placed in hook 7 bottom end vicinities; Winch electric switch is controlled in winch 4 one sides in operating personal station; Before lifting, coiling rope 5 is put down and is about to install near object, and reserve certain rich amount, by the staff of opposite side, hanging object is connected with hook 7, the simple lifting that two staff's cooperations can complete weight operates.
Although by reference to the accompanying drawings preferred embodiment of the present utility model is described above; but the utility model is not limited to the above-mentioned specific embodiment; the above-mentioned specific embodiment is only schematic; be not restrictive; those of ordinary skill in the art is under enlightenment of the present utility model; not departing from the scope situation that the utility model aim and claim protect, can also make the concrete conversion of a lot of forms, within these all belong to protection domain of the present utility model.
