The specific embodiment
Embodiment in the face of the utility model elaborates down; Present embodiment is being to implement under the prerequisite with the utility model technical scheme; Provided detailed embodiment and concrete operating process, but the protection domain of the utility model is not limited to following embodiment.
Shown in as depicted in figs. 1 and 2, present embodiment comprises support 1, assembly pulley 6, stay cord 2, rocking bar 3, base 4 and pull bar 5; For realizing more labour-saving pull-up cathead 7; The assembly pulley 6 of present embodiment comprises first pulley 61, second pulley 62, the 3rd pulley 63 and the 4th pulley 64; Said first pulley 61 and second pulley 62 are connected to the top of pull bar 5; The 3rd pulley 63 and the 4th pulley 64 are connected to the top of support 1, and an end fixed support 1 of stay cord 2, the other end of stay cord 2 are fixed on the rocking bar 3 after passing first pulley 61, the 3rd pulley 63, second pulley 62 and the 4th pulley 64 successively; The bottom of support 1 is connected on the base 4, and rocking bar 3 is arranged on the support 1, and the bottom of pull bar 5 is connected on the attachment face of cathead 7.
Like Fig. 2 and shown in Figure 4, in the present embodiment, the bottom of support 1 is movably connected on the base 4 through rotating shaft 11, and base 4 is provided with latch 41, and support 1 is provided with the jack that is used with said latch 41.Support 1 is horizontal positioned in cathead 7 transportations, vertically places in the installation process, can be through latch 41 location.
Like Fig. 3 and shown in Figure 5; In the present embodiment, first pulley 61, second pulley 62 are identical with the connection mode of the 3rd pulley 63, are example with first pulley 61; First pulley 61 comprises rotating shaft 611 and roller 612; Roller 612 is socketed in the rotating shaft 611 and can 611 rotates around the shaft, and the two ends of rotating shaft 611 are connected respectively on the steel pipe 613 with fixing its axial location, and guaranteeing does not axially have big displacement.The rotating shaft two ends of first pulley 61 and second pulley 62 are fixed on the top of pull bar 5 through steel pipe, and the 3rd pulley 63 rotating shaft two ends are fixed on the top of support 1 through steel pipe.The rotating shaft two ends of the 4th pulley 64 directly are fixed on the top of support 1.
The 3rd pulley 63 is positioned on the line of centers of first pulley 61 and second pulley 62, said stay cord 2 and the axis normal of the 4th pulley 64 that is positioned on second pulley 62 and the 4th pulley 64.Guarantee that the 4th pulley 64 does not receive or receive the effect of minimum axial force, the hand shaken bar is more laborsaving.The position of the 4th pulley 64 rationally is set, and the axial force of guaranteeing to receive on second pulley 62 reduces or does not have.
