The other end of described lifting beam is equipped with the counterweight box that can place clump weight.
The utility model organically combines hoisting device and dolly, the Hydraulic for lifting load dolly can flexiblely move to the position that equipment assembles and keeps in repair, realization is lifted by crane parts, can't use capable crane or capable crane to cause the problem of parts assembling and maintenance difficult thereby solved operation field.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the right elevation of Fig. 1;
Fig. 3 is that A among Fig. 1 is to view;
Fig. 4 is that B among Fig. 1 is to view.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, the Hydraulic for lifting load dolly comprises vehicle frame 13, wheel, hoisting device, two front-wheels 17 of wheel are wheel flutter, two trailing wheels 14 all attach footbrake sheet 15, hoisting device is by column 4, lifting hydraulic cylinder 11, sliding beam 9, lifting beam 2, pulley mechanism constitutes, column 4 is welded on the vehicle frame 5, lifting hydraulic cylinder 11 lower ends are connected with vehicle frame 13, lifting hydraulic cylinder 11 upper ends are connected with sliding beam 9, a pair of first roller 10 that can roll along column is installed on the sliding beam 9, lifting beam 2 is positioned at sliding beam 9 tops, certain intervals is equipped with two pairs of second rollers 3 that can roll along column on the lifting beam 2, the 3rd roller 5, one end of lifting beam 2 is equipped with Lift hook 7, and the other end is equipped with the counterweight box 1 that can place clump weight.Pulley mechanism has two groups with column 4 axis left-right symmetric, every group has comprised Hanging roller 18 and by two fixed pulleys 16, two assembly pulleys that movable pulley 8 constitutes, fixed pulley 16 is installed on the vehicle frame 13, movable pulley 8 is installed on the sliding beam 9, playing Hanging roller 18 is positioned at lifting beam 2 tops and is installed on the column 4, steel rope 6 one ends are connected on the vehicle frame 13, and steel rope 6 is alternately walked around movable pulley 8 successively, fixed pulley 16 has been walked around the Hanging roller 18 back other ends again and has been connected on the lifting beam 4; The foot pump 12 that promising lifting hydraulic cylinder 11 provides hydraulic oil is installed on the vehicle frame 13.
During use, lifting beam 2 is dropped to lowest order, to need mounted component to hang on the Lift hook 7, and in counterweight box 1, add clump weight and fix, step on the foot valve of foot pump 12 with pin continuously with lifting rope, hydraulic oil enters lifting hydraulic cylinder 11, lifting hydraulic cylinder 11 piston rods stretch out, and sliding beam 9 is lifted by lifting hydraulic cylinder 11 pistons, and movable pulley 8 rises along column 4 with sliding beam 9, steel rope 6 drives lifting beam 2 and rises along column 4, and the parts that hang on the Lift hook 7 are raised thereupon.Promote to step on footbrake sheet 15 after handrail 19 moves to job position with dolly, the dolly brake is fixing, and the foot valve of stepping on foot pump 12 then continuously is with the sling height of needs of parts.When finishing the lifting task or need readjust the position, only need open the unloader valve of hydraulic circuit, lifting beam 2 just can slowly fall.Foot pump, lifting hydraulic cylinder, unloader valve and other Hydraulic Elements connect by conventional hydraulic circuit.The application of assembly pulley has two effects: the one, realize that the stroke of lifting beam 2 is several times of lifting hydraulic cylinder piston stroke, and the 2nd, can reduce the suffered pulling force of steel rope 6.
