Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the adjustable complete machine lifting tool of the center of gravity for marine low speed diesel engine described in the utility model is described in further detail, but protection domain of the present utility model should do not limited with this.
Embodiment
Refer to Fig. 1 and Fig. 2, it is illustrated that the center of gravity adjustable complete machine lifting tool for marine low speed diesel engine includes lifting tool body 1, multiple lifting nut 3, four latches 4 of 2, two lateral pins and four split pins 5.The crane capacity of whole lifting tool is 140T, and single lateral pin 3 carries 70T.
Referring to Fig. 3, described lifting tool body 1 is imitative cover type, including base plate 1-2, locating ring 1-1, multiple nut centring ring 1-3, annular hoisting board 1-4, hoisting board 1-6 placed in the middle and two pieces of side hoisting board 1-5.
Described base plate 1-2 is circular steel plate, described annular hoisting board 1-4 is cylindrical shape steel beam column, described hoisting board 1-6 placed in the middle and two pieces of side hoisting board 1-5 is plain plate, this annular hoisting board 1-4, hoisting board 1-6 placed in the middle and both sides hoisting board 1-5 are vertically welded to above described base plate 1-2, described hoisting board 1-6 placed in the middle and both sides hoisting board 1-5 is positioned at the cylinder of described annular hoisting board 1-4, and these two pieces of side hoisting board 1-5 are positioned at the both sides of described hoisting board 1-6 placed in the middle.For the needs being easy to manufacture, lifting tool body 1 has needed substantial amounts of welding work step, and therefore the present embodiment has selected the CL.B material that welding performance is good.
The through lifting eye offering coaxial line on described annular hoisting board 1-4, hoisting board 1-6 placed in the middle and two pieces of side hoisting board 1-5, said two lateral pin 3 is inserted in this lifting eye.Referring to Fig. 1, in order to prevent described lateral pin 3 from play occurring in lifting process, described four latches 4 are inserted in the two ends of said two lateral pin 3 respectively, these two lateral pins 3 are positioned and to be prevented the horizontal looseness of lateral pin 3.Described four split pins 5 are inserted in the end of described four latches 4 respectively, to be fixedly mounted on by latch 4 on described lateral pin 3, it is ensured that it is firm that described lateral pin 3 is installed.
Said two lateral pin 3 is load bearing component, connects hoisting wirerope for directly installing or uses shackle.In order to meet steel wire rope and shackle user demand and lifting strength demand, lateral pin 3 needs to ensure enough bending strengths, therefore have employed 40CrNiMoA material, consider safety coefficient factor (safety coefficient is taken as 3 times), the diameter being obtained lateral pin 3 by strength check is 100mm, therefore the diameter of the lifting eye on annular hoisting board 1-4, hoisting board 1-6 placed in the middle and side hoisting board 1-5 is decided to be 102mm, the height of lifting eye is 160mm.
The diameter meeting the steel wire rope of 70T crane capacity is 95mm, and for ensureing the installation of steel wire rope, annular spacing between hoisting board 1-4 and side hoisting board 1-5, hoisting board 1-6 placed in the middle is decided to be 120mm；Owing to the shear stress that in lifting process, lateral pin 3 applies is born at the top of annular hoisting board 1-4, hoisting board 1-6 placed in the middle and two pieces of side hoisting board 1-5, therefore strength check is passed through, it is determined that the height of annular hoisting board 1-4, hoisting board 1-6 placed in the middle and two pieces of side hoisting board 1-5 is 320mm.Consider the moment of flexure on base plate 1-2 between from described annular hoisting board 1-4 to lifting nut 2, pass through strength check, it is determined that the thickness of base plate 1-2 is 80mm.
Referring to Fig. 3, described locating ring 1-1 is cylindrical shape steel beam column, is vertically welded to below described base plate 1-2.The effect of this locating ring 1-1 is to cooperate with cylinder cap and installs, and according to by lifting type, the excircle dimension of described locating ring 1-1 is 830mm, due to for non-bearing parts, therefore has selected 15mm sheet metal to weld.
The plurality of nut centring ring 1-3 is welded in the periphery of described base plate 1-2 equably, in conjunction with consulting Fig. 2, for placing by the cylinder head bolts of lifting type.The size of described nut centring ring 1-3 is determined according to the height of this cylinder head bolts, for ensureing the smooth installation of lifting nut 2, considers the height of described locating ring 1-1 and base plate 1-2, and the height of described centring ring 1-3 is defined as 85mm.
Refer to Fig. 1, the plurality of lifting nut 2 is uniformly distributed in the periphery of described lifting tool body 1 and is positioned on described nut centring ring 1-3, this lifting nut 2 is connected with the cylinder head bolts through described nut centring ring 1-3, is fixedly connected with by lifting Diesel Engine Complete Machine by described complete machine lifting tool.
This utility model can realize the adjustment at lifting center by adjusting the said two lateral pin 3 installation site on described lifting tool body 1, and detailed process is as follows:
When the installation site of two lateral pins 3 is as in figure 2 it is shown, when being installed on the annular two ends of hoisting board 1-4 and two pieces of side hoisting board 1-5, the structure centre of diesel engine is lifted by crane at lifting center；When two lateral pins 3 installation site as shown in Figure 4, one lateral pin 3 is installed on annular hoisting board 1-4 and side hoisting board 1-5, when another lateral pin 3 is installed on hoisting board 1-6 placed in the middle and another side hoisting board 1-5, lifting center will be offset 85mm by structure centre, as it is shown in figure 5, thus reach to compensate the effect of marine low speed diesel engine centre-of gravity shift.
This utility model solves the lifting problem of the marine low speed diesel engine of 6 cylinder head bolts gauche forms, it is achieved that lifting center lateral shift compensate function, enable marine low speed diesel engine complete machine comparatively steady, safe carry out handling.Test proves that, this utility model manufacture is simple, and easy making process is with low cost, is suitable for batch micro operations, it is possible to meet produced on-site needs.
