Description
Technical field
The utility model relates to the repair apparatus of power plant, is specifically related to the off-line repair apparatus of screw air compressor host.
Background technology
Traditional air compressor host maintenance mode mainly relies on the driving lifting in the workroom, floor space is bigger, it is longer to take the crane gear time, need many people's operations, the aid of employing during maintenance is more, maintainer's labour intensity is bigger, and operating efficiency is lower, unsafe hidden danger that the mixed and disorderly tool of working environment is bigger.Every maintenance process operations of the maintenance of air compressor host does not have fixed routine, mainly relies on the maintainer manually arbitrarily to carry out.All kinds of mass property adjustment after the overhaul of the equipments, measuring condition can't satisfy accurate Testing requirement, and the mantenance data statistical management can't execution standardization.
The utility model content
The purpose of this utility model is to overcome above-mentioned maintenance process operations does not have that all kinds of mass propertys after fixed routine, the overhaul of the equipments can't accurately be measured, the mantenance data statistical management can't execution standardization and maintenance exists potential safety hazard, defective that maintenance efficiency is low, provide a kind of air compressor host that makes in arbitrary angle rotary, optional position lifting, no longer need the screw air compressor host turning lifting workover rig of other annexes during maintenance operation.
Realize that the utility model purpose technical scheme is: a kind of screw air compressor host turning lifting workover rig, an elevating screw and two that comprises Vertical Rack, is fixed on the frame is positioned at the guide rail of elevating screw both sides, the lifting motor that is connected with elevating screw one end, comprise also being installed on described two guide rails and following elevating screw to rotate and the unit head that moves up and down that this unit head comprises servomotor, the gearbox that connects successively, the load-bearing bearing housing and a coupling that is connected with main shaft and a transmission nut that cooperates with described elevating screw that contains main shaft.
Preferably, described servomotor is a rotating servo motor.
Preferably, described coupling is the plug-in type coupling.
Preferably, described coupling has the connecting portion that is connected with the head flange of screw air compressor host.
Owing to adopted above-mentioned technical solution, the every maintenance process operations that has solved maintenance part in the present air compressor host overhaul of the equipments does not fully have all kinds of mass propertys after fixed routine, the overhaul of the equipments and adjusts measuring conditions and can't satisfy the problem that accurate Testing requirement, mantenance data statistical management can't execution standardizations.The present technique solution can reduce the several of lifting, reduces the input of human resources, has increased safety coefficient.Air compressor host can require at arbitrary angle rotary the optional position lifting according to maintenance operation.No longer need other annexes during operation, overhaul efficiency can improve 3-5 doubly.
Description of drawings
Fig. 1 is the utility model screw air compressor host turning lifting workover rig structural representation;
Fig. 2 is the side view of Fig. 1.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and embodiments.
With reference to Fig. 1-2, a kind of screw air compressor host turning lifting workover rig, an elevating screw 7 and two that comprises Vertical Rack 5, is fixed on the frame is positioned at the guide rail 6 of elevating screw 7 both sides, the lifting motor 8 that is connected with elevating screw 6 one ends, comprise also being installed on described two guide rails and following elevating screw to rotate and the unit head 9 that moves up and down that this unit head 9 comprises servomotor 1, the gearbox 2 that connects successively, the load-bearing bearing housing 3 and a coupling 4 that is connected with main shaft and a transmission nut that cooperates with described elevating screw that contains main shaft.This screw air compressor host turning lifting workover rig is installed on the ground 10 by Vertical Rack 5.
Described servomotor 1 can be rotating servo motor.
Described coupling 4 can be the plug-in type coupling.
Described coupling 4 has the connecting portion that is connected with the head flange of screw air compressor host.
Screw air compressor host turning lifting workover rig of the present utility model is furnished with maintenance guiding book and maintenance flow, adopts software operation control, and form is undertaken by menu mode.According to the software operation prompting of this maintenance flow, the maintainer carries out every maintenance, makes the maintenance operation no longer rely on the maintainer manually not have fixed routine and arbitrarily carries out, help improving overhaul efficiency.
Screw air compressor host turning lifting workover rig of the present utility model lifting is furnished with hand held controller control and panel by waiing upon the clothes motor-driven.By the lifting arbitrarily in allowed limits of hand held controller control screw air compressor host, it is spacing to be provided with limit, and lower position-arresting is the frame base 600MM that disembarks, and upper position-arresting is the frame base 1800MM that disembarks.Upset drives by waiing upon clothes driven by motor deceleration system, can control respectively by hand held controller and panel.Can set automatic flip angle, also can manually set arbitrarily and carry out arbitrary overturn.From as can be seen last, screw air compressor host turning lifting workover rig of the present utility model possesses the turning lifting function, can stop the performance that maintenance is implemented in the back in the arbitrary fixed-site of three dimensions during overhaul of the equipments.Crane gear only need hang screw air compressor host on the screw air compressor host turning lifting workover rig of the present utility model when beginning, hangs down by this crane gear during end.In the process of maintenance, no longer need to use crane gear, solved the long problem of crane gear time that takies.No longer need other annexes when carrying out maintenance operation.Overhaul efficiency can improve 3-5 doubly.
The record sheet of the built-in air compressor machine maintenance of screw air compressor host turning lifting workover rig of the present utility model simultaneously has the function of record self-clocking.Also have with the line database function.Can immediately write down maintenance activity safe mode, fault, phenomenon of the failure, solution, education time, go out to repair the record of time, maintenance back calibrating, the accurate measurement data of all kinds of mass propertys is carried out the double copies of above-mentioned all data simultaneously.Thereby realized maintenance mode with the overhaul of the equipments automation of mechanical device platform.
Use the utility model device, air compressor host is connected and installed to the turning lifting workover rig by flange, just can carry out lifting and upset to main frame, be not subjected to the restriction in space and place, and it is easy to operate, production on-site environment can effectively be controlled, and singlely just can independently finish, and has improved the security of operation.This utility model can reduce the several of the lifting of crane gear simultaneously, thereby has reduced the input of human resources.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
