Specific embodiment
It should be noted that in the case where not conflicting, the embodiment in the present invention and the feature in embodiment can phases
Mutually combination.Describe the present invention in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
Of the present invention being hinged refers to that two parts are connected by bearing pin, and two parts relative with respect to pin joint can turn
It is dynamic.
With reference to Fig. 1 to 3, the preferred embodiments of the present invention are described in further detail,
As shown in figure 1, currently preferred crawler crane, crawler crane is that one kind carries out material lifting, transport, dress
The runabout crane of operation such as unload and install, be one of most important main force's crane in handling facilities.Crawler crane bag
Include creeper undercarriage 1, turntable 2, principal arm 3, setting-up mast 5, mast 9, main variable amplitude rope 10, main transformer width arm-tie 6, setting-up variable amplitude rope
4th, super-starting balance weight 8, the first arm-tie 77.Turntable 2 is arranged on creeper undercarriage 1.Principal arm 3 and setting-up mast 5 pass through with turntable 2
Bearing pin is connected, and principal arm 3 realizes that the luffing of principal arm 3 is acted in the presence of main variable amplitude rope 10.Setting-up mast 5 is in setting-up variable amplitude rope 4
Realize that the luffing of setting-up mast 5 is acted under effect, setting-up radius, setting-up radius are adjusted by adjusting the change angle of setting-up mast 5
Refer to horizontal range of the top of setting-up mast 5 to the pivot of turntable 2.
As shown in Fig. 2 truss arm reducing machine of the invention is applied on crawler crane, for connecting setting-up mast 5
With the device of super-starting balance weight 8.Truss arm reducing machine of the invention includes truss arm 13, the first arm-tie 7, the second arm-tie the 11, the 3rd
Arm-tie 12, the 4th arm-tie 14, truss support 15.
The lower end of first arm-tie 7 is hinged with the upper end of the second arm-tie 11；The upper end of first arm-tie 7 is connected (as schemed with setting-up mast 5
Shown in 1).First arm-tie 7 includes four rows, and the two of left side ranked first arm-tie 7 is connected with the upper end of the second arm-tie of left side 11, right side
Two ranked first arm-tie 7 is connected with the upper end of the second arm-tie of right side 11.In addition, the first arm-tie 7 can also only have two rows or more
Row.
The two ends of 3rd arm-tie 12 are hinged with two upper ends of the second arm-tie 11 of left and right sides respectively；Cut with scissors respectively at the two ends of truss arm 13
Connection arm-tie 18 is connected to, two lower ends of the second arm-tie 11 of connection arm-tie 18 and left and right sides of the left and right sides are connected by the first bearing pin 16
Connect；Two upper ends of the 4th arm-tie 14 of left and right sides are connected with the two ends of truss arm 13 respectively, two lower ends of the 4th arm-tie 14 of left and right sides point
It is not connected with super-starting balance weight 8；The middle part of the upper end of truss support 15 and truss arm 13 is connected, the lower end of truss support 15 and super-starting balance weight
8 are connected.The length of the 3rd arm-tie 12 be less than the length of truss arm 13, therefore left and right two the second arm-ties 11 and the 3rd arm-tie 12 and
Truss arm 13 and connection arm-tie 18 constitute up-narrow and down-wide trapezium structure.
As shown in figure 4, truss arm 13 is formed by connecting by two section truss by bearing pin.Can also only one section truss composition.Such as
Shown in Fig. 4, the triangle frame geometry that truss arm 13 is made up of multiple straight-bars.Straight-bar can be steel pipe, angle steel, rectangle
The forms such as pipe, square tube, steel plate bending, are formed, triangle frame geometrical form by welding or bolt connection.
Truss arm reducing machine of the invention, the first arm-tie 7, the second arm-tie 11, three arm-ties, the 4th arm-tie 14 are tension
Part, using pulling plate structure, can bear larger axial tension.First arm-tie 7, the second arm-tie 11, three arm-ties, the 4th arm-tie 14
The structure that multiple arm-ties are hinged is, in addition, the first arm-tie 7, the second arm-tie 11, three arm-ties, the 4th arm-tie 14
Tiebar structure can be used.Truss arm 13 is pressure containing part, using truss structure, can bear larger axial compressive force, improves purlin
Boom reducing machine bearing capacity and raising stability.
As shown in figure 3, truss arm reducing machine installation process of the invention is as follows：
Because under gravity, the second arm-tie 11 is naturally drooped before installing, setting-up radius is adjusted, make the second arm-tie 11
Pin-and-hole is aligned with the pin-and-hole of connection arm-tie 18, is inserted into the first bearing pin 16, the second arm-tie 11 is connected with arm-tie 18 is connected.
After connecting, truss falsework 17 of dismantling, and truss falsework 17 is removed, truss support 15 is fixed to
On super-starting balance weight 8 (or super-starting balance weight link).Regulation setting-up radius, declines two the 4th arm-ties 14 of left and right sides, by left and right
The 4th arm-tie 14 of side two is connected with super-starting balance weight 8.
A kind of truss arm reducing machine and crawler crane that the present invention is provided, bearing capacity are high, convenient to disassembly, cost
Low cost, good stability.
Presently preferred embodiments of the present invention is the foregoing is only, is not intended to limit the invention, it is all in essence of the invention
Within god and principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
