Detailed description of the invention
It should be noted that, in the situation that not conflicting, the feature in embodiment and embodiment in the present inventionCan mutually combine. Describe below with reference to the accompanying drawings and in conjunction with the embodiments the present invention in detail.
Of the present inventionly hingedly refer to that two parts connect by bearing pin, two parts pin joint relativelyRelatively rotate.
Below in conjunction with Fig. 1 to 3, the preferred embodiments of the present invention are described in further detail,
As shown in Figure 1, the preferred crawler crane of the present invention, crawler crane be one carry out material lifting,The runabout crane of the operations such as transport, handling and installation is most important main force crane in handling facilitiesOne of. Crawler crane comprises creeper undercarriage 1, turntable 2, principal arm 3, has surpassed mast 5, mast 9,Main transformer width rope 10, main transformer width arm-tie 6, luffing rope 4, super-starting balance weight 8, the first arm-tie 77 are surpassed. Turntable 2Be arranged on creeper undercarriage 1. Principal arm 3 with surpassed mast 5 and be connected by bearing pin with turntable 2, principal arm3 realize principal arm 3 luffing actions under the effect of main transformer width rope 10. Surpass mast 5 and surpassed luffing rope 4The lower realization of effect surpassed mast 5 luffing actions, surpassed mast 5 change angles by adjusting, and adjusts and surpassesRadius, has surpassed radius and has referred to and surpassed the horizontal range of mast 5 tops to turntable 2 pivots.
As shown in Figure 2, truss arm reducing machine of the present invention is to be applied on crawler crane, super for connectingPlay the device of mast 5 and super-starting balance weight 8. Truss arm reducing machine of the present invention comprises that truss arm 13, first drawsPlate 7, the second arm-tie 11, the 3rd arm-tie 12, the 4th arm-tie 14, truss support 15.
The first arm-tie 7 lower ends and the second arm-tie 11 upper ends are hinged; The first arm-tie 7 upper ends with surpassed mast 5Connect (as shown in Figure 1). The first arm-tie 7 comprises four rows, and two of left side ranked first arm-tie 7 and left side secondArm-tie 11 upper ends are connected, and two of right side ranked first arm-tie 7 and is connected with the second arm-tie 11 upper ends, right side.In addition, the first arm-tie 7 also can only have two rows or more rows.
The 3rd arm-tie 12 two ends are hinged with two the second arm-tie 11 upper ends of left and right sides respectively; 13 liang of truss armsEnd is hinged with respectively and connects arm-tie 18, connection arm-tie 18 and two the second arm-ties 11 of left and right sides of the left and right sidesLower end connects by the first bearing pin 16; Two the 4th arm-tie 14 upper ends of left and right sides respectively with truss arm 13 two endsConnect, two the 4th arm-tie 14 lower ends of left and right sides are connected with super-starting balance weight 8 respectively; On truss support 15End is connected with truss arm 13 middle parts, and truss support 15 lower ends are connected with super-starting balance weight 8. The 3rd arm-tie 12Length be less than truss arm 13 length, therefore two the second arm-ties 11 in left and right and the 3rd arm-tie 12 and truss arm13 and connect arm-tie 18 form up-narrow and down-wide trapezium structure.
As shown in Figure 4, truss arm 13 is formed by connecting by bearing pin by two joint truss. Also can only one save trussForm. As shown in Figure 4, the triangle frame geometry that truss arm 13 is made up of multiple straight-bars. Straight-bar canTo be the forms such as steel pipe, angle steel, rectangular tube, square tube, steel plate bending, be formed by connecting by welding or bolt,Form triangle frame geometrical form.
Truss arm reducing machine of the present invention, the first arm-tie 7, the second arm-tie 11, three arm-ties, the 4th arm-tie 14Be and be subject to draw piece, adopt pulling plate structure, can bear larger axial tension. The first arm-tie 7, second drawsPlate 11, three arm-ties, the 4th arm-tie 14 are multiple arm-ties structure forming that is hinged, in addition, and firstArm-tie 7, the second arm-tie 11, three arm-ties, the 4th arm-tie 14 also can adopt Tiebar structure. Truss arm 13For pressure containing part, adopt truss structure, can bear larger axial compressive force, improve the carrying of truss arm reducing machineAbility and raising stability.
As shown in Figure 3, truss arm reducing machine installation process of the present invention is as follows:
Before installing, due under Action of Gravity Field, the second arm-tie 11 naturally droops, and regulates and has surpassed radius, makes secondThe pin-and-hole of arm-tie 11 is aimed at the pin-and-hole that is connected arm-tie 18, then inserts the first bearing pin 16, makes the second arm-tie11 be connected arm-tie 18 and connect.
After connecting, the truss falsework 17 of dismantling, and truss falsework 17 is removed, truss is propped upFrame 15 is fixed to (or super-starting balance weight link) on super-starting balance weight 8. Regulate and surpassed radius, make left and right sides twoIndividual the 4th arm-tie 14 declines, and two the 4th arm-ties 14 of left and right sides are connected with super-starting balance weight 8.
A kind of truss arm reducing machine provided by the invention and crawler crane, bearing capacity is high, and easy accessibility is fastVictory, cost is low, good stability.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, not all at thisWithin bright spirit and principle, any amendment of doing, be equal to replacement, improvement etc., all should be included in thisWithin bright protection domain.
