Abstract
The to -be -solved technical problem of the utility model is to provide a strap self -locking function jack -up gallows, improve work efficiency. Putting up fixing bolt by left socle and gallows crossbeam, right branch and being connected, the hoist tackle utilizes two driving plates and transmission nut round pin to link. Lead screw bearing frame bottom plate one end is fixed on the left socle, and is shang mian fixed with the bearing frame. The lead screw passes through screw thread and transmission nut hookup, fixes on the bearing frame with two nuts behind the left end installed thrust bearing. The beneficial effect of the utility model: the hoist tackle has self -locking function, can be in the whole scope locking of crossbeam when lifting by crane. Installed thrust bearing on the lead screw, the resistance is little, adjust laborsaving convenience. Can the wide application in heavier or location such as compressor bearing case lid, thrust bearing set spare expects much the spare part installation.
Description
Technical field
A kind of strop auto-lock function lifting hanger is used for requiring higher to lifting, accurate positioning.Safety is high, the parts dismounting lock at any time coaster and installation.Mainly be applicable to machine manufacture, repairing, field repaired by petrochemical complex, natural gas line centrifugal compressor.
Background technology
In plant maintenance and maintenance, lifting is had high requirements.Existing small-sized tackle block is not with horizontal limit devices, and during hanging piece stressed out of plumb, tackle block moves and causes danger.General by manpower control, operating difficulties, the large danger of labour intensity is high.When requiring accurately location and cooperation in mechanical erection process, if tackle block effect of inertia can cause economic loss by part of damage.
Utility model content
The technical problems to be solved in the utility model there is provided a kind of strop auto-lock function lifting hanger, increases work efficiency, and reduces labour intensity, prevents safety misadventure from occurring.Possess lead screw transmission accurately to locate and tackle block auto-lock function simultaneously.
The technical scheme of the utility model technical solution problem is: a kind of strop auto-lock function lifting hanger is connected by bolt of rear end plate with hanger beam, right support by left socle, and tackle block utilizes two driver plates and the link of driving nut pin.Leading screw pedestal base one end is fixed on left socle, fixes above with bearing seat.Leading screw is connected with driving nut by screw thread, is fixed on bearing seat after left end installed thrust bearing with double nuts.
The beneficial effects of the utility model: tackle block has auto-lock function, can lock at crossbeam global extent during lifting.Installed thrust bearing on leading screw, resistance is little, adjust laborsaving convenience.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Fig. 1 is a kind of strop auto-lock function lifting hanger structural representation.1. left socles in figure, 2. leading screw pedestal base, 3. hanger beam, 4. tackle block, 5. leading screw, 6. right support, 7. double nuts, 8. thrust baring, 9. bearing seat, 10. driver plate, 11. driving nuts, 12. bolt of rear end plates.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is further illustrated, but should not be construed as restriction of the present utility model.A kind of strop auto-lock function lifting hanger is connected to form load larrying member by left socle (1) and hanger beam (3), right support (6) by bolt of rear end plate (12) as shown in Figure 1, tackle block (4) is upper mobile at hanger beam (3), utilize two driver plates (10) wherein on plate hole and the upper downside pin of driving nut (11) coordinate.Driving nut has rotational freedom but sway is limited, and be less than equivalent friction angle owing to selecting threads of lead screw lift angle so can self-locking, when leading screw does not turn, driving nut (11) can lock, and tackle block just possesses auto-lock function.Leading screw pedestal base (2) one end is fixed on left socle (1), fixes above with bearing seat (9).Leading screw (5) is connected with driving nut (11) by screw thread, and left end installed thrust bearing (8) reduces friction drag, accurate flexibly during rotational lead screw.Rear end adopts double nuts (7) structural adjustment endplay, guarantees that leading screw is at the upper relative position of bearing seat (9).
Under normal working, tackle block lifting object gravitate, vertical ground.Tackle block is not by Lateral Force, and driver plate and driving nut do not stress.When lifting thing is by external force, time particularly lateral stressed, tackle block is by Lateral Force, and be delivered on leading screw by driver plate and driving nut, leading screw is then delivered to bearing seat by thrust baring.On the support structure, because threads of lead screw lift angle is less than equivalent friction angle, leading screw can not rotate in final effect, and driving nut and tackle block would not move.Achieve the function of tackle block full range automatic locking.When needs accurate adjustment coaster horizontal position, rotational lead screw drives the driving nut just mobile tackle block of energy.Owing to have employed thrust bearing.Reduce resistance, leading screw right-hand member adopts short radius of turn handle, the arm of force 60 millimeters, and compact conformation, one hand can operate.After adjusting to the right place, decontrol handle and just can complete self-locking.Tackle block stop motion.When needing reverse mobile tackle block, rotate backward leading screw handle.
Claims (3)
