Abstract
A cylinder cover puller comprises a pull lead screw and a base plate sleeved on the pull lead screw. One end of the pull lead screw is provided with external threads matched with an internal thread hole in a cylinder cover, and the other end of the pull lead screw is connected with a fastened nut through threads. The pull lead screw located on the front end of the fastened nut is further sleeved with a flat gasket. The cylinder cover puller is simple in structure, convenient to operate, safe and reliable, and applied to maintenance operation of multi-cylinder reciprocation plunger pump or a slurry pump. The cylinder cover provided with the threads on the top can be taken out from a valve hole provided with a small clearance or a small interference through one-shot installation. The cylinder cover puller is time-saving, and labor-saving, and greatly improves work efficiency.
Description
Technical field
The utility model relates to the maintenance tool that multi-cylinder reciprocating pump or slush pump are used, and is specially a kind of drawbench that the threaded cylinder cap in top is taken out from the valve opening of little gap or slight interference.
Background technology
In the use procedure of slush pump and multi-cylinder reciprocating pump, often can change spool, valve seat.Gland nut and cylinder cap need to be taken out when changing, because cylinder cap is under the extruding of gland nut, cylinder cap and valve opening may produce adhesion, should not take out.General method is at present, after use is loosening with cylinder cap by hammer with the slip of leading screw, it is being extracted, and wastes time and energy.
Summary of the invention
The purpose of this utility model is exactly the defective for prior art, and a kind of reasonable in design, easy to operate, time saving and energy saving cylinder cap drawbench is provided.
Its technical scheme is: comprise the upper backing plate that is set with of drawing leading screw and its, drawing leading screw one end is provided with the external screw thread that cooperates with internal thread hole on the cylinder cap, the other end clamp nut that is threaded.
Also be set with plain cushion on the drawing leading screw of described clamp nut front end.
The utility model is simple in structure, easy to operate, safety and stability; Be applied in the maintenance activity of multi-cylinder reciprocating pump or slush pump, once mounting can be taken out the threaded cylinder cap in top from the valve opening of little gap or slight interference, time saving and energy saving, has greatly improved operating efficiency.
Description of drawings
Fig. 1 is structural representation of the present invention.
Among the figure: 1, drawing leading screw, 2, backing plate, 3, plain cushion, 4, nut.
The specific embodiment
The present invention is described further below in conjunction with accompanying drawing and specific embodiment.
A kind of cylinder cap drawbench comprises drawing leading screw 1 and the backing plate 2 that is set with on it, and drawing leading screw 1 one ends are provided with the external screw thread that cooperates with internal thread hole on the cylinder cap, and the other end connects plain cushion 3 and clamp nut 4 successively.
During operation, place backing plate 2 at surface of the work, drawing leading screw 1 passes the backing plate mesopore and external screw thread one end is tightened in the internal thread at cylinder cap top, puts plain cushion 3, and fastening nut 4 pulls out cylinder cap at once from endoporus.The utility model also uses the working condition with other similar structures simultaneously.
