The specific embodiment

Below in conjunction with accompanying drawing, the preferred embodiment of the invention is elaborated.

As shown in Fig. 1 to 2, a direction is the length direction of I-beam section 9, and b direction is the Width of I-beam section 9.As reference, the electric block as shown in Fig. 1 to 2, mainly comprises walking dolly 1, reel 2, the first motor 3, movable pulley 4, suspension hook 5, hawser 8.Wherein walking dolly 1 is installed on I-beam section 9 and in I-beam section 9 walkings; Reel 2, for the hawser 8 of reeling, is fixed on walking dolly 1 along the side of I-beam section length direction; The first motor 3 is also fixed on walking dolly 1 along the side of I-beam section length direction, for providing power to reel 2; Movable pulley 4 is located at walking dolly 1 below and in bottom, is fixed with suspension hook 5.Walking dolly 1 is also separately installed with fag end fixed part 6, quiet pulley assembly 7 along the both sides of I-beam section length direction, and hawser 8 one end are fixed on fag end fixed part 6, and the other end is wound on reel 2 and through movable pulley 4 and quiet pulley assembly 7.Reel 2, the first motor 3 are installed on to the side of walking dolly 1, are conducive to increase walking dolly 1 lifting space below, increased the sling height of electric block; Utilize movable pulley 4 that hawser 8 is connected on fag end fixed part 6 and reel 3, the weight that reel 2 is born reduces half, can effectively reduce the horsepower output of the first motor 3, or the maximum hoisting weight of electric block can be doubled; And fag end fixed part 6 and quiet pulley assembly 7 be located at respectively walking dolly 1 along the both sides of I-beam section length direction, make electric block when hoisting heavy, keep balance.

In the present embodiment, as shown in Figs. 3-4, walking dolly 1 mainly comprises pillar stiffener 11, driving wheel 14, the second motor 15, flower wheel 16.

Wherein, pillar stiffener 11 is four, is symmetrical arranged and perpendicular to horizontal surface, cross section surrounds into rectangle; 11 of two pillar stiffeners that parallel with I-beam section Width are provided with adjustable column 12, and 11 of two pillar stiffeners that parallel with I-beam section length direction are provided with cross bar 13; Adjustable column 12 is positioned at pillar stiffener 11 bottoms, for regulating the distance of 11 of the pillar stiffeners of I-beam section Width, to be adapted to the I-beam section of different size; Cross bar 13 is positioned at pillar stiffener 11 tops, is respectively used to install fag end fixed part 6, quiet pulley assembly 7.

Flower wheel 16 has four, is installed on respectively pillar stiffener 11 along the inner side of I-beam section length direction and in same level, and the opposite flank of flower wheel 16 is provided with column-shaped projection 161, for the weight of walking and carrying electric block on I-beam section 9.

Driving wheel 14 can be one, also can be two, and it is located at pillar stiffener 11 inner sides, middle part and is meshed with corresponding flower wheel 16 respectively.In the present embodiment, driving wheel 14 is preferably two and be fixed on a pipe link 141, and this pipe link 141 is rotatably arranged in pillar stiffener 11 middle parts and parallels with I-beam section Width.The second motor 15 is fixed on pillar stiffener 11 and with one of them driving wheel 14 and is meshed.When the second motor 15 work, drive the driving wheel 14 be meshed with it to synchronize rotation, and then utilize pipe link 141 to drive another driving wheel 14 synchronously to rotate, keep two driving wheels 14 synchronously to rotate, four flower wheels 16 are also synchronously rotated, the oblique phenomenon of race that in the time of can effectively reducing electric block load-bearing like this, the asynchronous rotation of driving wheel 14 and flower wheel 16 causes.

Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and implement according to this; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
