Description
Technical field
The utility model relates to a kind of suspender, specifically is a kind of three-jaw suspender that is used for the handling wheel hub.
Background technology
In the prior art, the handling of wheel hub, construction and installation are passed the mounting hole on the wheel hub by manual work with suspender belt or steel cable, lift by crane with crane again.Suspender belt or steel cable because wheel hub can wear and tear are prone to accidents, and the steel cable lifting also damages wheel hub easily.In addition, the three hook suspender handling wheel hubs of employing are arranged also, but need manual hanging hook separately with three hook suspenders, manual operation is inconvenient, also has the Personal Risk in the wheel hub eminence.Sometimes suspender meeting bump injury machined surface causes damage to wheel hub.And the structure of some wheel hub is not suitable for adopting three hook handlings.
Summary of the invention
The purpose of the utility model is to overcome the deficiency that exists in the prior art, and a kind of three-jaw suspender simple in structure, ingenious, rational is provided, and this suspender easy-to-operate is not easy to damage wheel hub.
The technical scheme that provides according to the utility model: a kind of three-jaw suspender; It is characterized in that: comprise flap seat, suspension rod, big suspension hook, main steel rope, middle steel cable, assembly pulley and receipts pawl steel cable; Said flap seat has three well-distributed bearings along the circumferential direction, and each bearing all is connected with the afterbody of a suspension rod is hinged through pin; Said big suspension hook be arranged on flap seat directly over, be connected with steel cable in the middle of three main steel ropes and on the big suspension hook, the lower end of said three main steel ropes is connected with the middle part of said three suspension rods respectively, said in the middle of the lower end of steel cable hang assembly pulley; The fixed end of said receipts pawl steel cable is connected on the flap seat, is passed down through the hole at flap seat center after the free end of receipts pawl steel cable penetrates assembly pulley and walks around pulley, so that moving with pulling.
Further improvement as the utility model; Said assembly pulley comprises the pulley case and fixed pulley, movable pulley within it is installed; The top of said pulley case is connected the lower end of said middle steel cable; Fixed pulley and movable pulley all are contained in the pulley case rotationally, and movable pulley is positioned at the fixed pulley below; Its length direction of said pulley case upper edge offers the guiding stria, and the wheel shaft two ends of said movable pulley place in the guiding stria, movable pulley can be in the pulley case lifting moving; On the free end of said receipts pawl steel cable elder generation follow-up pulley one side direction, walk around behind the fixed pulley downwards, walk around again behind the movable pulley upwards, pass downwards and from the hole at flap seat center after walking around fixed pulley at last once more.
As the further improvement of the utility model, an end of said pin is equipped with the spring cotter that prevents that pin from deviating from.
The utility model compared with prior art, advantage is: simple in structure, ingenious, reasonable, easy-to-operate is not easy to damage wheel hub; Assembly pulley can play laborsaving effect, can realize reaching the folding and unfolding of suspension rod with pulling the moving free end of receiving the pawl steel cable.
Description of drawings
Fig. 1 is the structural front view of the utility model.
Fig. 2 is the three-dimensional structure diagram of the utility model.
The specific embodiment
Below in conjunction with concrete accompanying drawing and embodiment the utility model is described further.
As shown in the figure, described three-jaw suspender is mainly used in the handling wheel hub, its mainly by flap seat 1, suspension rod 2, pin 3, hang dog clutch 4, spring cotter 5, main steel rope 6, receive pawl steel cable 7, parts such as assembly pulley 8, middle steel cable 9 and big suspension hook 10 form.
As shown in Figure 1, said flap seat 1 has three well-distributed bearing 1a along the circumferential direction, and each bearing 1a all is connected with the afterbody of a suspension rod 2 is hinged through pin 3; One end of said pin 3 is equipped with the spring cotter 5 that prevents that pin 3 from deviating from; Said big suspension hook 10 be arranged on flap seat 1 directly over; Be connected with three main steel ropes 6 and a middle steel cable 9 on the big suspension hook 10; The lower end of said three main steel ropes 6 is connected through hanging dog clutch 4 with the middle part of said three suspension rods 2 respectively, and assembly pulley 8 is hung in the lower end of said middle steel cable 9; The fixed end of said receipts pawl steel cable 7 is connected on the flap seat 1, is passed down through the hole at flap seat 1 center after the free end of receipts pawl steel cable 7 penetrates assembly pulley 8 and walks around pulley, so that moving with pulling.
As shown in Figure 1, said assembly pulley 8 mainly is to play laborsaving effect, so that pull operation.Graphic assembly pulley 8 is mainly organized 8 one-tenth by pulley case 8a and installation fixed pulley 8b, movable pulley 8c within it; The top of said pulley case 8a is connected the lower end of said middle steel cable 9; Fixed pulley 8b and movable pulley 8c all are contained in the pulley case 8a rotationally, and movable pulley 8c is positioned at fixed pulley 8b below; Its length direction of said pulley case 8a upper edge offers the guiding stria, and the wheel shaft two ends of said movable pulley 8c place in the guiding stria, movable pulley 8c can be in pulley case 8a lifting moving; On the follow-up pulley 8c of the free end of said receipts pawl steel cable 7 elder generation one side direction, walk around behind the fixed pulley 8b downwards, walk around again behind the movable pulley 8c upwards, pass downwards and from the hole at flap seat 1 center after walking around fixed pulley 8b at last once more.
