Description
Technical field
The present invention relates to equipment hoisting technical field, more particularly, relate to a kind of bipod mast Lift-on/Lift-off System being convenient to movement.
Background technology
For lifting operations such as the hoisted in position of equipment and the loading-unloading vehicles of object, the most desirable, most convenient, the most efficiently method utilize crane to carry out.But for the equipment of restricted clearance and the handling of object such as in narrow workyard, factory building, storehouse, framed structure, because crane oad cannot enter more greatly, or the situations such as crane armed lever cannot lift, cannot rotate, also or crane resources lack environment, the have more than is needed crane of profit carries out hoisting operation, and the method erectting mast usually can only be adopted to carry out lifting operation.
Bipod mast, due to easy accessibility, good, the required stable cable wind rope of lateral stability is less, hoisting capacity is large, solid durable, to the adaptable feature in narrow, that operational space is limited workyard, so the more other forms of mast of bipod mast applies in lifting operation widely.
Traditional bipod mast lifting, is generally that lifting scene utilizes two steel pipe top intersections to place, utilizes steel rope multiple-turns wound, infall puts on a suit of armour hoist cable, for being hang the bont such as hoist crane or polyspast, after mast is erect, front and back all need to draw to establish cable wind rope, as shown in Figure 1.This hanging method has some shortcoming following: the bipod mast that (1) is traditional, and column steel pipe is because of arranged in a crossed manner, and lifting load causes the pressure of disalignment to it, steel pipe strained condition is not good; (2) traditional bipod mast, is directly held on chock bottom column steel pipe, and two steel pipes just inner side two points stress (bottom Fig. 1, two arrows are indicated local), causes steel pipe to bear eccentricity pressure, make steel pipe strained condition not good further; (3) traditional bipod mast, at more equipment in time lifting, when lifting an other equipment after having lifted an equipment often, need remove mast, then reinstall, process is time-consuming.
Summary of the invention
1. invent the technical matters that will solve
The object of the invention is to overcome the deficiency of the problems referred to above in prior art, provide a kind of bipod mast Lift-on/Lift-off System being convenient to movement, this system bipod mast can be socketed on fork truck fast, assembling is simple, mobile convenient, once assemble, substantially can complete the lifting task that whole work area is all, and the bipod mast in the present invention, rational in infrastructure, use procedure strained condition is good, compared with traditional flip's mast, identical material and specification, can lift heavier equipment.
2. technical scheme
For achieving the above object, technical scheme provided by the invention is:
A kind of bipod mast Lift-on/Lift-off System being convenient to movement of the present invention, comprise fork truck, bipod mast, cable wind rope and power lifting appliance, described bipod mast forms chevron pointing by two mast columns, shackle plate is accompanied between mast column top described in two, two mast columns and shackle plate is connected and top is provided with lamina tecti, described shackle plate is trapezoidal tabular, two jiaos, shackle plate bottom place respectively offers a hanger hole, mast column bottom described in two is the hinged cover of hinge respectively, and hinge cover opening direction is parallel with shackle plate in-plane; Described bipod mast is socketed in a fork truck front portion fork root by hinge cover, and is provided with support chain between the forklift door frame of fork truck and bipod mast; Described cable wind rope one end is connected to shackle plate and fork truck belongs to bipod mast hanger hole on one side together, and another hanger hole of described shackle plate is connected with power lifting appliance, for lifting weight.
As further improvement of the present invention, described mast column bottom is provided with some mast free bearings having hole, and described hinge cover top is provided with some hinge cover free bearings having hole, described mast free bearing with cut with scissors overlap free bearing intersect merge by straight pin mutually hinged.
