For achieving the above object, the technical solution of the utility model is as follows:
A kind of heavily loaded energy-conservation jack up unit, comprise reel and suspender, also comprise counterweight, described counterweight and described suspender are respectively by the both sides of wire rope hanging at described reel, quality and the amassing of stroke of described counterweight are a steady state value, described suspender quality and weighting lifting quality and be also this steady state value with the long-pending of the stroke that hoists.
Further, described weighting lifting quality is five ten ten to percent 4 percent of rated load weight.
Further, the quality of described counterweight be described suspender quality and weighting lifting quality and, described counterweight stroke is identical with the stroke that hoists.
Further, the pulley system multiplying power of described counterweight is identical with the pulley system multiplying power of described suspender.
Further, the quality of described counterweight be described suspender quality and weighting lifting quality and 2 times, described counterweight stroke is 1/2nd of the stroke that hoists.
Further, the pulley system multiplying power of described counterweight is 2 times of the pulley system multiplying power of described suspender.
Further, also comprise motor, retarder and drg, described motor to be in transmission connection described reel by described retarder, and described drg is braked described reel.
Further, described reel is two, and each described reel is wound around two hoist ropes and a counterweight armored rope, and described hoist rope connects described suspender, and described counterweight armored rope connects described counterweight.
Further, a pressure of the left end at described reel in described two hoist ropes is restricted, and another root at the right-hand member pressure rope of described reel, and is rear end rope stretching, and in the middle of described hoist rope, pressure is restricted and front end rope stretching.
The beneficial effects of the utility model are, the utility model compared with prior art, adds counterweight in the utility model, balancing lifting article, thus reduce the driving power of lifting needed for article, realize energy-saving and cost-reducing, reduce the use cost of jack up unit, there is very strong marketable value.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 and Fig. 2 is heavy duty of the present utility model energy-conservation jack up unit principle of work schematic diagram;
Fig. 3 is the energy-conservation jack up unit structural representation of heavy duty of the present utility model;
Fig. 4 is reel wiring structural representation in the energy-conservation jack up unit of heavy duty of the present utility model;
Fig. 5 is heavy duty of the present utility model energy-conservation jack up unit adjustment process schematic diagram.
Detailed description of the invention
The exemplary embodiments embodying the utility model feature & benefits will describe in detail in the following description.Be understood that the utility model can have various changes in different embodiments, it neither departs from scope of the present utility model, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit the utility model.
As depicted in figs. 1 and 2, it is heavy duty of the present utility model energy-conservation jack up unit principle of work schematic diagram, the energy-conservation jack up unit of heavy duty of the present utility model comprises reel 1, suspender 2 and counterweight 3, counterweight 3 and suspender 2 respectively by the both sides of wire rope hanging at reel 1, as shown in Figure 1.Wherein, the steel rope connecting suspender 2 is hoist rope 4, and the steel rope connecting counterweight 3 is counterweight armored rope 5, and hoist rope 4 and counterweight armored rope 5 are all arranged by pulley guiding, as shown in Figure 2.
In the utility model, when suspender pulley block ratio is identical with counterweight pulley block ratio, the quality of counterweight 3 be the quality of suspender 2 and weighting lifting quality and, weighting lifting quality is five ten ten to percent 4 percent of rated load weight.Therefore, the utility model hoisting capacity when zero load is five ten ten to percent 4 percent of rated load weight, and at full load hoisting capacity is six ten ten to percent 5 percent of rated load weight.
In the utility model, when suspender pulley block ratio is different with counterweight pulley block ratio, as shown in Figure 5, counterweight 3 stroke S1, hoist stroke S2, counterweight 3 pulley system multiplying power m1, lifting mechanism pulley multiplying power m2, counterweight 3 quality G1, suspender 2 quality and weighting lifting quality and be G2, then: m1 × S1=m2 × S2; M1/G1=m2/G2.That is: if S1=S2, then m1=m2, G1=G2; If S1=1/2S2, then m1=2m2, G1=2G2; By that analogy.
When the utility model is used on door frame, if door frame supporting leg stroke limiting, by regulating the multiplying power of counterweight 3 assembly pulley to shorten stroke, the weight of corresponding adjustment counterweight 3 simultaneously.
As shown in Figure 3, the utility model also comprises motor 6, retarder 7 and drg 8, and motor 6 to be in transmission connection reel 1 by retarder 7, and drg 8 pairs of reels 1 are braked.In the utility model, reel 1 is two, drives, braked by different drgs 8 respectively by two different motors 6.Wherein, each reel 1 is wound around two hoist ropes 4 and a counterweight armored rope 5, and hoist rope 4 connects suspender 2, and counterweight armored rope 5 connects counterweight 3.
Traditional motor of motor 6 power ratio in the utility model reduces about 50%, and a whole set of drive system, comprises retarder 7, all corresponding reduction of drg 8 model.To whole electrical drive system, comprise the electric components such as motor 6, frequency converter, controller, cable, when type selecting all by corresponding reduction.Because electric system cost is higher, account for about 60% of complete machine cost, this will reduce the cost of electric-control system greatly.
As shown in Figure 4, in the utility model, a pressure of the left end at reel 1 in two hoist ropes 4 is restricted, and another root at the right-hand member pressure rope of reel 1, and is rear end rope stretching, and in the middle of hoist rope 5, pressure is restricted and front end rope stretching.
In the utility model decline process, hoist rope 4 puts rope, counterweight armored rope 5 rope closing; Hoist in process, hoist rope 4 rope closing, counterweight armored rope 5 puts rope.Structure of the present utility model is also formed by carrying out transformation on traditional reel structure, and this transformation process is without the need to increasing reel length, simple and convenient.
The beneficial effects of the utility model are, the utility model compared with prior art, adds counterweight 3 in the utility model, balancing lifting article, thus reduce the driving power of lifting needed for article, realize energy-saving and cost-reducing, reduce the use cost of jack up unit, there is very strong marketable value.
The technical solution of the utility model is disclosed as above by preferred embodiment.The change that those skilled in the art do when should recognize the scope and spirit of the present utility model disclosed in the claim do not departed from appended by the utility model and retouching, within the protection domain all belonging to claim of the present utility model.
