Description
Technical field
The utility model relates to a kind of bont technical field of construction machinery and equipment, specifically a kind of welded type assembly pulley framework.
Background technology
Construction machinery and equipment is in building, engineering, use very extensive in the operations such as transportation, the particularly lifting of goods or when transhipment, its bont plays an important role, assembly pulley is as the major part in the bont, in practical work process, because environment is abominable, often be in high temperature, high load capacity, high worn-down environment, damage easily, the assembly pulley framework on the construction machinery and equipment generally adopts bolted form at present, and there is following defective in the assembly pulley framework of this structure: stressing conditions is not good, sheave shaft only depends on the support of biside plate, sizable moment of flexure and shearing are born, discontinuity equalization, the easy to wear and flexural deformation of sheave shaft in the middle part; Assembly pulley framed structure middle part sub-unit is a forging, and then by bolted form, the bolted connection steadiness is poor, and forging is difficult for processing, and the manufacturing cost height.
Summary of the invention
In order to overcome above-mentioned defective, it is a kind of rational in infrastructure that the utility model provides, and load-carrying capacity is big, the welded type assembly pulley framework that reliability is high.
The technical solution adopted in the utility model is: a kind of welded type assembly pulley framework, comprise gin wheel framing and lifting hook pulley framing, described gin wheel framing comprises the side plate in two tape spool holes, dividing plate, base plate and two otic placodes, two otic placodes are arranged side by side on top, two side plates are arranged on the both sides of two otic placodes, the top of side plate is welded to connect with an otic placode, base plate is welded to connect the bottom at two side plates, between two side plates, be provided with at least one dividing plate, dividing plate top and two otic placodes are welded to connect, its underpart and base plate are welded to connect, and the dividing plate middle part is provided with the hole that can supply sheave shaft to pass; Described lifting hook pulley framing comprises clamping plate, dividing plate II, top board and the connecting plate in two tape spool holes, top board is arranged on the below of the base plate of gin wheel framing, two clamping plate are separately positioned on the both sides of top board, the top and the top board of clamping plate are welded to connect, connecting plate is welded on the lower position of two clamping plate, be provided with dividing plate II between two clamping plate, dividing plate II is provided with the hole that can supply sheave shaft to pass, and the dividing plate quantity of the quantity of dividing plate II and gin wheel framing is corresponding.
The utility model all is provided with dividing plate in gin wheel framing and lifting hook pulley framing, increased the strong point of sheave shaft, has reduced the moment of flexure and the shearing of sheave shaft, makes sheave shaft not easy to wear in the course of the work, is difficult for bending or being out of shape; Adopt between each parts of gin wheel framing of the present utility model and lifting hook pulley framing to be welded to connect, improved the integrated carrying ability, strengthened reliability, the safety of assembly pulley.
Description of drawings
Fig. 1 is the scheme drawing of the utility model gin wheel framing
Fig. 2 is the scheme drawing of the utility model lifting hook pulley framing
The specific embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, mainly be made up of gin wheel framing and lifting hook pulley framing, wherein the gin wheel framing comprises side plate 1, dividing plate 2, base plate 3 and two otic placodes 4 in two tape spool holes.Two otic placodes 4 are arranged side by side on top, two side plates 1 are arranged on the both sides of two otic placodes 4, the top of side plate 1 is welded to connect with an otic placode 4, base plate 3 is welded to connect the bottom at two side plates 1, between two side plates 1, be provided with at least one dividing plate 2, dividing plate 2 in the present embodiment is two, the top of dividing plate 2 and two otic placodes 4 are welded to connect, its underpart and base plate 3 are welded to connect, and dividing plate 2 middle parts are provided with the hole that can supply sheave shaft to pass, and sheave shaft passes dividing plate 2, its two ends are connected with two side plates 1, pulley is contained on the sheave shaft, and the present embodiment middle pulley can be installed three, and is separated by dividing plate 2.
General and the gin wheel framing of lifting hook pulley framing is used, the lifting hook pulley framing is arranged on the below of gin wheel framing, and steel rope connection by twining on the pulley, described lifting hook pulley framing comprises the clamping plate 5 in two tape spool holes, dividing plate II 6, top board 7 and connecting plate 8, top board 7 is arranged on the below of the base plate 3 of gin wheel framing, two clamping plate 5 are separately positioned on the both sides of top board 7, the top of clamping plate 5 and top board 7 are welded to connect, connecting plate 8 is welded on the position between the bottom of two clamping plate 5, between two clamping plate 5, be provided with dividing plate II 6, dividing plate II 6 is provided with the hole that can supply sheave shaft to pass, sheave shaft in the lifting hook pulley group passes dividing plate II 6, its two ends are connected with two clamping plate 5, dividing plate 2 quantity of the quantity of dividing plate II 6 and gin wheel framing are corresponding, and the quantity of present embodiment median septum II 6 also is two.The effect of dividing plate II 6 is the same with dividing plate 2 in the gin wheel framing, works to support sheave shaft and separates pulley, prevents that situations such as wearing and tearing and flexural deformation from appearring in sheave shaft.
This shows that pulley group frame of the present utility model has rational in infrastructure, bearing capacity is big, reliability height, the characteristics such as long service life.
