Abstract
The invention discloses a cable input dynamic grab bucket which is used for solving the problems of hydraulic pipelines and reducing the production difficulty and production cost of grab buckets. According to the technical scheme, a hydraulic pump station of the cable input dynamic grab bucket is arranged in a component in the grab bucket, power is input by a cable, and the cable is connected to the component in the grab bucket by a winding drum and a guide wheel.
Description
Technical field
The present invention relates to a kind of structure of grab bucket, particularly relate to hydraulic power unit and be arranged in grab bucket inside, the grab bucket that power is inputted by cable.
Background technology
Grab machine is similar to hoisting crane, also be a kind of weight-lifting equipment, with general hoisting crane by comparison, many pull up circuits controlling grab bucket opening and closing in lifting mechanism, such as common hoisting crane has two steel rope connecting shackles to be responsible for hoisting, so grab bucket and just have four steel ropes, wherein the use that hoists is responsible in two connection grab buckets, another two opening and closings being responsible for grabbing bucket.But the design and manufacture cost of the grab machine of traditional steel cord structure is higher, and installed power is large not, is difficult to be applied to the huge occasion of power requirement.
And the heat radiation of hydraulic power unit and sealing all have problems, the grab bucket of each model configures hydraulic power unit separately, grab bucket manufacture difficulty and cost all relatively high.
Summary of the invention
The object of the invention is to solve the problem, provide the grab bucket of a kind of cable input power formula, solve the problem of hydraulic tubing, reduce manufacture difficulty and the cost of manufacture of grab bucket.
Technical scheme of the present invention is: present invention is disclosed the grab bucket of a kind of cable input power formula, it is inner that hydraulic power unit is arranged in grab bucket, and power is inputted by cable, and cable is connected to grab bucket intraware by reel, track adjusting wheel.
According to an embodiment of cable input power formula grab bucket of the present invention, reel is mounted on hull.
According to an embodiment of cable input power formula grab bucket of the present invention, hydraulic power unit is arranged in grab bucket intraware.
According to an embodiment of cable input power formula grab bucket of the present invention, in grab bucket inner component, hydraulic power unit connects oil cylinder.
According to an embodiment of cable input power formula grab bucket of the present invention, in the underwater sealing assembly of cable, hold-down bolt and earth stud stationary body, packing ring, sealing are padded on junction and seal.
According to an embodiment of cable input power formula grab bucket of the present invention, a cooling system is comprised in hydraulic power unit, be formed by connecting by sea chest and hydro oil storage tank, hydraulic oil in hydro oil storage tank utilizes the seawater in sea chest to cool, when grab bucket is in underwater, the water in sea chest and outside seawater carry out exchanging the temperature in sea chest is maintained in setting range.
The present invention contrasts prior art following beneficial effect: the solution of the present invention hydraulic power unit is arranged in grab bucket inside, and by cable input power, relative to prior art, because the size of cable is less than hydraulic oil pipe, therefore arrange cable drum and lead all more convenient, and hydraulic power unit is positioned at grab bucket inside, hydraulic tubing problem is easier to solve.
Accompanying drawing explanation
Fig. 1 shows the constructional drawing of the preferred embodiment of cable input power formula of the present invention grab bucket.
Fig. 2 shows the schematic diagram that grab bucket of the present invention is arranged.
Fig. 3 shows the schematic diagram of hermetically-sealed construction of the present invention.
Fig. 4 shows the schematic diagram of the cooling system in grab bucket of the present invention.
Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention will be further described.
Fig. 1 shows the structure of the preferred embodiment of cable input power formula of the present invention grab bucket.Refer to Fig. 1, in the grab bucket of the cable input power formula of the present embodiment, hydraulic power unit is arranged in grab bucket intraware 1, by cable 3 input power, cable 3 by being arranged on reel 2 on hull, track adjusting wheel 4 is connected to grab bucket intraware 1.Cable is input on the pumping plant in grab bucket by three reels, the requirement such as demand fulfillment is easily wound around, seawater operation (80 meters of depth of water), tension, speed are fast.Further as shown in Figure 2, in grab bucket intraware 1, the hydraulic power unit 5 be arranged in grab bucket intraware connects oil cylinder 6.
Refer to Fig. 3, show the underwater sealing structure of cable, hold-down bolt 7 and earth stud 8 stationary body 9 and pressing plate 12, packing ring 10, packing seal 11 seal in junction.By the full watertight piggyback pod of such as Fig. 3 design, all power units and electric-control system wherein integrated.
Comprise a cooling system as shown in Figure 4 in hydraulic power unit, the heat balance of whole closed piggyback pod needs to adopt this cooling system.Cooling system is formed by connecting by sea chest and hydro oil storage tank, hydraulic oil in hydro oil storage tank utilizes the seawater in sea chest to cool, when grab bucket is in underwater, the water in sea chest and outside seawater carry out exchanging the temperature in sea chest is maintained in setting range.
Above-described embodiment is available to those of ordinary skill in the art to realize and uses of the present invention; those of ordinary skill in the art can be without departing from the present invention in the case of the inventive idea; various modifications or change are made to above-described embodiment; thus protection scope of the present invention not limit by above-described embodiment, and should be the maximum range meeting the inventive features that claims are mentioned.
