Abstract
A split screw pump stator dismounting tool is applied to the maintenance and fixation of screw pump stators of large and medium-sized screw pumps. The two rectangular steel plates are respectively bent into a semicircle, two ends of the semicircle are respectively provided with a fixing lug, and a fixing hole is drilled on the fixing lugs; the two half ring bodies are opposite to form a circular ring body; fixing a screw and a nut; the end part of the fixed lug at one end of the semi-ring body is connected with a handle, and the two handles are respectively arranged at the two sides of the ring body. The effect is as follows: the stator is fixed on the screw pump stator, and is easy to control during assembly and disassembly, so that the stator is prevented from swinging back and forth or drooping; the volume is small, the weight is light, and when the equipment is disassembled and assembled, the tool exerts force in one direction, so that the time and the labor are saved. The screw pump stator dismounting tool is suitable for dismounting large and medium-sized screw pump stators.
Description
Technical field
The utility model relates to the flight-line maintenance technical field, and the instrument that particularly large and medium-sized screw pump maintenance is used is a kind of dismantling device of split type screw pump stator.
Background technology
Not only the maintenance personal is many, the operating time is long when maintenance for domestic large and medium-sized screw pump, and labour intensity is big; Because the environment and the space of maintenance are less, feasible originally not only do not bring into play its effect with maintenance tool, bring potential safety operation hidden danger to the maintenance personal on the contrary.Especially there is not the screw pump stator tool specially for attaching and detaching.
The utility model content
The purpose of the utility model is: a kind of split type screw pump stator dismantling device is provided, is fixed on the screw pump stator, can direction of rotation carry out installation or removal.Improve maintenance work efficient, reduce staff labor intensity.
The technical scheme that the utility model adopts is: split type screw pump stator dismantling device comprises handle, two hemizonids, screw and nut.It is characterized in that: the steel plate that two block lengths are square curves semicircle respectively, at semicircular two ends fixedly ear is arranged respectively, fixedly is being drilled with fixing hole on the ear; Two hemizonids are formed a torus relatively; In fixing hole, be installed with screw respectively, nut is fixed on the screw; End at hemizonid fixedly is connected with handle in the ear end, and two handles are respectively in the torus both sides.A handle is connected to a semicircular fixedly ear, and two parts of instrument are docking together and form a complete circle, carries out fasteningly promptly can using in the enterprising enforcement of screw pump.The ability direction of rotation is carried out the installation or removal of equipment.
The width of described rectangular steel plate is 30mm, and thickness is 3～5mm,
Described handle, fixedly ear and hemizonid adopt a block plate to process, and handle is vertical each other with the plane of fixing ear.
The beneficial effect of the utility model: the split type screw pump stator dismantling device of the utility model, be fixed on during maintenance on the screw pump stator, easy control stator during dismounting overcomes that stator swings back and forth or sagging; Volume is little, and is in light weight, and during disassemblerassembler, instrument firmly in one direction, and is time saving and energy saving.Be applicable to the dismounting of large and medium-sized screw pump stator.
Description of drawings
Fig. 1 is the split type screw pump stator dismantling device of a utility model structural representation.
Fig. 2 is the vertical view of Fig. 1
Among the figure, 1-handle, 2-hemizonid, 3-screw, 4-nut.
The specific embodiment
Embodiment 1: with a split type screw pump stator dismantling device is example, and the utility model is done further explain.
Consult Fig. 1.The split type screw pump stator dismantling device of the utility model comprises handle 1, two hemizonids 2, two screws 3 and two nuts 4.
The width of rectangular steel plate is 30mm, and thickness is 5mm, and the steel plate that two block lengths are square curves semicircle respectively, at semicircular two ends fixedly ear is arranged respectively, fixedly is being drilled with fixing hole on the ear; Two hemizonids 2 are formed a torus relatively, and the size of internal diameter determines according to stator outer diameter.In fixing hole, be installed with screw 3 respectively, nut 4 is fixed on the screw 3; End at hemizonid 2 fixedly is connected with 1, two handle 1 of handle respectively in the torus both sides in the ear end.Handle 1, fixedly ear and hemizonid 2 adopts a block plate to process, and handle 1 is vertical each other with the plane of fixing ear.A handle is connected to a semicircular fixedly ear, and two parts of instrument are docking together and form a complete circle.
