Description
Technical field:
The present invention relates to a kind of low clearance dolly that is used for hoisting crane.
Background technology:
At present, the conventional hoist dolly is that trolley frame is designed to the planar structure that box beam is formed, and is the demarcation line with plane on the trolley frame, and top is lifting mechanism, the bottom is a hardware, and the parts of lifting mechanism arrange with planar fashion that all the maximum height of dolly is of a size of the vertical distance between dolly top vertex and trolley frame nadir, and this dolly appearance structure size is huge, Heavy Weight, it is in light weight to the hoisting crane requirement to satisfy the user, and overall dimensions are little, the requirement that scope of work is big.Most importantly producer's construction investment of conventional hoist is bigger.
Summary of the invention:
The objective of the invention is in order to overcome above deficiency, provide that a kind of cost cost is low, scope of work is wide, steady quality, dependable performance, the low clearance dolly that is used for hoisting crane that energy consumption is low.
Purpose of the present invention is achieved through the following technical solutions: a kind of low clearance dolly that is used for hoisting crane, comprise trolley frame, be provided with crossbeam between the front and rear part of trolley frame, be provided with dead sheave in the crossbeam, the dead sheave below is connected with suspension hook, also be provided with two operating units in the trolley frame, two operating units place the front and rear part of trolley frame respectively, also be provided with lifting mechanism between the front and rear part of trolley frame, lifting mechanism places a side of crossbeam, lifting mechanism is by reel, the spherical roller coupler, bearing seat, the axle of taking the lead hoists, reductor, plate disc brake and electrical motor are formed, before the reel, latter two end all links to each other with the front and rear part of trolley frame by the spherical roller coupler, run through in the front portion of trolley frame and be provided with described bearing carrier ring, run through in the bearing carrier ring and be provided with the axle of taking the lead that hoists, the take the lead end of axle of hoisting links to each other with the front end of reel by being positioned at anterior spherical roller coupler, the take the lead other end of axle of hoisting places the outside of trolley frame, the axle of taking the lead of hoisting places and is with the reductor that hoists of control on the exterior position of trolley frame, also be provided with the electrical motor of control operation between the front and rear part of trolley frame, electrical motor places a side of reel, and electrical motor is provided with plate disc brake.
The present invention compared with prior art has the following advantages: the method for designing that the low clearance dolly breaks traditions, and the layout of lifting mechanism and the characteristics of metal construction are mutually combined, and make full use of three dimensional space, form three-dimensional vehicle structure.It is " worker " font spatial structure that the dolly design type changes " well " word planar structure; Change the arrangement of traditional steel cable winding system, the dead sheave group is sidelong in the trolley frame crossbeam; The reductor that hoists of control adopts the outer suit mode that hangs, and the axle of taking the lead of hoisting is fixed in the bearing seat, hoist take the lead axle half be welded in the trolley frame, adopt this mode to reduce the bottom-to-top-height of dolly, saved traditional understructure; Change lifting hook pulley group version, be complementary with the layout of dead sheave group; Drg adopts plate disc brake, makes dolly lifting mechanism space diminish mechanism's compactness; The hoisting, move and adopt full frequency conversion of dolly among the present invention, it is more steady that operation is hoisted, and can save a large amount of electric energy simultaneously; Crane job scope with low clearance dolly is big, from heavy and light, wheel load is little, energy consumption is low, steady quality, dependable performance, guaranteed the stable of complete machine performance.
Description of drawings:
