Description
Technical field
The utility model relates to lifting equipment technical field, is a kind ofly specifically applicable to the otic placode of travelling block and the taper sleeve type drop handle pin that can assemble from any direction be fixedly connected with between lower drop handle.
Background technique
The conventional Connecting format of travelling block otic placode and lower drop handle is pin type drop handle pin as shown in Figure 5, one end of this drop handle pin is the table top with step, the part coordinated with otic placode and lower drop handle is cylindrical body, and the other end is the nut be threaded with drop handle pin body.Can only install or remove from the side of otic placode during assembling, after drop handle pin and lug plate holes deform, drop handle pin disassembles being difficult to, and brings difficulty to the replacing of lower drop handle, therefore requires high to the processing in lug plate holes and lower drop handle hole, assembly precision.
Model utility content
The purpose of this utility model is to provide a kind of taper sleeve type drop handle pin, to solve pin type drop handle pin can only carry out lower drop handle assembling from the side of otic placode, adds the higher problem of required precision to the pilot hole of otic placode and lower drop handle.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
A kind of taper sleeve type drop handle pin, it comprises drop handle pin body, and the two ends of described drop handle pin body are cone, and middle part is cylindrical body, the cone outer wall at described drop handle pin body two ends is socketed with tapered sleeve respectively, and the both sides, top of described drop handle pin body are connected with end plate respectively by bolt.
As further improvement of the utility model, the outer wall of described tapered sleeve is cylindric, and inwall is suitable cone-shaped with the cone at described drop handle pin body two ends, and the outer diameter of described tapered sleeve is identical with cylindrical diameter in the middle part of described drop handle pin body.
Further improve as of the present utility model, the cylindrical outer surface of described drop handle pin body is provided with oil groove, the oilhole communicated with described oil groove is axially arranged with along described drop handle pin body, described oilhole communicates with a bolt hole on described drop handle pin body top, is provided with lubricating cup in described bolt hole.
The beneficial effects of the utility model are:
(1) drop handle pin body is processed into two ends by the utility model is cone, middle part is cylindrical bipyramid pin structure, again tapered sleeve is installed at the cylindrical outer surface at two ends, drop handle pin body can assemble from any side of travelling block otic placode and lower drop handle, behind drop handle pin body plugging in fitting hole, tapered sleeve on the cover of the two ends of drop handle pin body, is finally fixed on two end faces of drop handle pin body with bolt by end face again; The utility model can the principle of self-locking when to make use of between drop handle pin body and tapered sleeve stressed, ensure that the join strength of lower drop handle and travelling block otic placode, also ensure that job safety when article lift simultaneously;
(2) the utility model can realize on-the-spot to the quick mounting between travelling block otic placode and lower drop handle, dismounting, reduces the labor intensity of operating personnel, the working efficiency of raising;
(3) the assembly precision requirement between travelling block otic placode and lower drop handle is effectively reduced;
(4) design of oil groove of the present utility model and oilhole, makes can realize internal lubrication between the surface of contact of drop handle pin body and travelling block otic placode, lower drop handle, is of value to the maintenance between component.
