Technical field
The utility model relates to a kind of offset water pump erecting device, belongs to mechanical field, specifically a kind of offset water pump Special lifting device.
Background technology
Water pump is the critical component of fire extinguishing tanker product, is the main power source of water blast gun, its assembly process and quality most important.The leak tightness of flange faying face must be ensured in fitting process.
Offset water pump fitting surface is top flange face and front side flange face.Above-mentioned flange face coordinates with water pipe end flange face respectively and closely prevents from seeping water.During assembling, first by offset water pump by bolt be connected with fixed beam fastening after connection for transmission axle and water pump front end flange again; Typically use lifting rope during present stage offset water pump lifting to lift by crane after water pump fixation, which cost is lower, but there is the sideslip of workpiece in hoisting process, reverse, phenomenon of colliding with, there is serious potential safety hazard, and cannot ensure that fitting surface meets technical requirements, there is stress during assembling, had a strong impact on flange faying face leak tightness, easily occurred the quality problems such as infiltration, corrosion.Therefore introducing the key content that a kind of safe, efficient, succinctly easy-to-use hanging apparatus is offset water pump Assembly Process planning, is also the important topic of technique assembling exploitation.
Summary of the invention
For above-mentioned prior art Problems existing, the utility model provides a kind of offset water pump Special lifting device, guarantees that in fitting process, each assembly flange face of water pump is without problems such as inclination, torsions, ensures unstressed generation in fitting process.Realize auto-lock function when hook clamping work pieces by thread rod, ensure Hoisting Security.
To achieve these goals, the technical solution adopted in the utility model is: a kind of offset water pump Special lifting device, comprise stage support, described stage support center has through hole, through hole is built-in with and steps up leading screw, step up leading screw top and be fixed with leading screw handle, step up leading screw and be set with pivoted housing through the bottom of through hole and bottom is fixed with top board; The periphery hinge joint of described stage support lower end has multiple hook, and described hook links in pivoted housing by pipe link; Described stage support top is fixed with guide rail, and be rotatably connected on the upside of guide rail suspension centre regulating plate, and suspension centre regulating plate can along slide.
Further, described suspension centre regulating plate lower end is fixed with slide device, and slide device is set on guide rail, realizes suspension centre regulating plate according to slide.
Further, described pivoted housing is built-in with and the negative thread stepping up leading screw and mate, and when stepping up screw turns, pivoted housing can rise thereupon or decline.
Preferably, adopt protective material with contact site, flange lower surface bottom described hook, effectively prevent flange face paint film from damaging.
The beneficial effects of the utility model are: as locking structure while of using screw drive pivoted housing to move, prevent workpiece in hoisting process from coming off, safety is higher; Can ensure during installation that offset water pump top flange fitting surface level, front end flange fitting surface are vertical, decrease stress in fitting process; Adopt protective material with contact site, flange lower surface bottom hook, can effectively prevent paint film from damaging, ensure presentation quality.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of offset water pump Special lifting device, comprises stage support 9, described stage support 9 center has through hole, through hole is built-in with and steps up leading screw 2, steps up leading screw 2 top and is fixed with leading screw handle 1, steps up leading screw 2 and is set with pivoted housing 7 through the bottom of through hole and bottom is fixed with top board 4; The periphery hinge joint of described stage support 9 lower end has three hooks 5, and described hook 5 links in pivoted housing 7 by pipe link 3; Described stage support 9 top is fixed with guide rail 6, and be rotatably connected on the upside of guide rail 6 suspension centre regulating plate 8, and suspension centre regulating plate 8 can slide along guide rail 6.
Further, described suspension centre regulating plate 8 lower end has been rotatably connected slide device 81, and slide device 81 is set on guide rail 6, realizes suspension centre regulating plate 8 and slides according to guide rail 6.
Further, described pivoted housing 7 is built-in with and the negative thread stepping up leading screw 2 and mate, and when stepping up leading screw 2 and rotating, pivoted housing 7 can rise thereupon or decline.
Preferably, adopt protective material with contact site, flange lower surface bottom described hook 5, effectively prevent flange face paint film from damaging.
When real work, as shown in Figure 2, rotating threaded shaft handle 1 drive step up leading screw 2 move and by screw thread pair drive pivoted housing 7 move.Pipe link 3 and pivoted housing 7 are linked by bearing pin, and when pivoted housing 7 moves, drivening rod 3 and hook 5 move and change opening angle to adapt to the flange diameter of water pump 10.Aligning hanging apparatus axis makes it overlap with the flange axis, top of water pump 10, and contrarotation leading screw handle 1 reduces the opening angle of hook 5 to clamp water pump 10 by the motion of screw thread pair and pipe link 3.
Use the hole for hoist on suspension hook hanging suspension centre regulating plate 8 to carry out examination to hang, hoisting point position is changed by regulating suspension centre regulating plate 8, guarantee that tractive force active line is by water pump center of gravity 11, the maintenance of observation water pump 10 top flange assembling simultaneously level, front end flange fitting surface 12 keep vertical, and result regulates sling point position until meet the requirements according to the observation.
In sum, the utility model structure is simple, convenient and practical, and as locking structure while adopting the motion of screw drive pivoted housing, prevent workpiece in hoisting process from coming off, safety is higher; Can ensure during installation that offset water pump top flange fitting surface level, front end flange fitting surface are vertical, decrease stress in fitting process; Adopt protective material with contact site, flange lower surface bottom hook, can effectively prevent paint film from damaging, ensure presentation quality.
