Abstract
The invention relates to a crane device, namely an energy-saving and environment-friendly dual-beam hook bridge crane. The energy-saving and environment-friendly dual-beam hook bridge crane comprises a main girder and crane carriages operating on the main girder, wherein a main crane carriage and a secondary crane carriage are respectively arranged on the main girder; a lifting main hook is arranged on the main crane carriage, and a secondary hook is arranged on the secondary crane carriage. For example, when a novel energy-saving and environment-friendly dual-beam hook bridge crane with 32/5 tons lifts an article less than five tons, the secondary crane carriage is operated, when the article more than five tons is lifted, the main crane carriage is operate, so as to achieve the electricity-saving purpose. The secondary hook is averagely utilized for three hours per day, and the annual power usage is 720 degrees by calculation according to 25 days per month, so only one energy-saving and environment-friendly dual-beam hook bridge crane with 32/5 tons can save 2880 degrees of commercial power per year. According to the calculation, a majority of cranes in the whole country can save a number of energy sources for the country after adopting the scheme. The energy-saving and environment-friendly dual-beam hook bridge crane has the advantages of being simple in structure and novel in pattern, and being energy-saving and environment-friendly.
Description
Technical field
The present invention relates to a kind of weight-lifting equipment, i.e. energy-saving and environmental protection twin beams overhead crane with hook.
Background technology
In existing weight-lifting equipment, general-purpose overhead crane is generally by crane carriage, and large and small car operating unit, crane span structure are formed.Common major and minor lifting mechanism is installed on the crane carriage more than 20 tons, hoist rated load and of main hook, the auxiliary hook little tonnage weight that hoists greater than the load of auxiliary hook load.When using auxiliary hook, wheeling mechanism is a low load with strong power, has wasted a large amount of electric energy, never causes the attention of country.With 32/5 ton of hoisting crane of standard QD type is example: the structural disadvantages of 32/5 ton of hoisting crane of standard is that major and minor hook is installed on the dolly simultaneously.Power when the operation power of motor of dolly is 32 tons of dollies (conduct oneself with dignity 10.8 tons) operation when using auxiliary hook adds the power of the 5 tons of weights that hoist, need 4KW, and the trolley travelling power of motor when carrying 5 tons of weights only needs 0.8KW.General workshop, the time of daily use auxiliary hook is basically more than 3 hours.On average used auxiliary hook 3 hours by every day, calculate 25 days every months, and annual power consumption is 3600 degree.If the trolley travelling power of motor 0.8KW during 5 tons of weights calculates by carrying, also by same Time Calculation, annual power consumption is 720 degree, and only 32/5 ton of hoisting crane of the accurate QD type of a station symbol is just wasted commercial power 2880 degree every year.
Summary of the invention
The objective of the invention is provides a kind of energy-saving and environmental protection twin beams overhead crane with hook of saving electric energy to above-mentioned deficiency.
Technical solution of the present invention is: energy-saving and environmental protection twin beams overhead crane with hook comprises the crane carriage that moves on girder, the girder.Divide on the girder to offer main crane carriage and secondary crane carriage, the main hook that hoists is installed on the main crane carriage, and auxiliary hook is installed on the secondary crane carriage.
With 32/5 ton of novel energy-conserving, environmental protection twin beams overhead crane with hook is example: the object below 5 tons of hoisting, move secondary crane carriage; Hoist object more than 5 tons moves main crane carriage, reaches purpose of saving.On average used auxiliary hook 3 hours by every day, calculate 25 days every months, and annual power consumption is 720 degree, and only one 32/5 ton energy-saving and environmental protection twin beams overhead crane with hook can be practiced thrift commercial power 2880 degree every year.By this reckoning, national most of hoisting crane adopts this kind scheme to can be country every year and practices thrift a considerable amount of energy.
Advantage of the present invention is: 1, simple in structure, modern design, attractive in appearance, from heavy and light, be fit to various model hoisting cranes and select for use.2, be the invention departure point with the saves energy, broken the conventional hoist design concept, though improvement simple in structure; But brought beyond thought energy-saving effect, changed the conventional way of decades, overcome the prejudice in the design; Be national saves energy, reduce carbon emission, effect is obvious, numeral is considerable; Especially existing hoisting crane is transformed that the back is energy-conservation, environment protecting is more remarkable, meets national energy-saving and emission-reduction policy, has high promotional value.
To combine accompanying drawing that embodiment of the present invention is described in further detail below.
Description of drawings
Fig. 1 is a structure diagram of the present invention.
Fig. 2 is Fig. 1 plan structure sketch.
The specific embodiment
Referring to Fig. 1,2; Energy-saving and environmental protection twin beams overhead crane with hook comprises the main crane carriage 2 and the secondary crane carriage 3 of operation on girder 1, the girder 1; The main hook 4 that hoists is installed on the main crane carriage 2; The auxiliary hook 5 that hoists is installed on the secondary crane carriage 3, and main crane carriage 2 drives respectively with secondary crane carriage 3.Main crane carriage 2 can be parked in girder 1 two ends respectively with secondary crane carriage 3.Coming to drive respectively main crane carriage 2 and secondary crane carriage 3 according to the weight of hoisting heavy, is purpose with economize on electricity, environmental protection.
According to the production needs, can flexible, convenient, fastly select crane carriage for use, avoid the low load with strong power phenomenon, reach economize on electricity, environmental protection purpose.
