Abstract
The utility model discloses a device for rapidly replacing a piston cup of an oil separating pump, comprising a guide sleeve and a door-shaped frame. The device is characterized in that an inner hole of the guide sleeve is a taper hole formed by a taper hole surface, a supporting hole is formed in a small end of the taper hole of the guide sleeve, the door-shaped frame is composed of uprights, cross beams, bases and jack bases, the cross beams are arranged at the upper ends of the two uprights, the bases are arranged at the lower ends of the two uprights, and the jack bases are fixed at the middle sections of the cross beams. When the device disclosed by the utility model is used for mounting a cup, the cup can be replaced without dismounting the whole piston head, the mounting quality can be guaranteed, and the replacing time can be shortened.
Description
Technical field
The utility model relates to a kind of piston cup installation auxiliary device, is specifically related to more changing device of a kind of oil isolation pump piston cup.
Background technology
Oil isolation pump is a kind of high pressure, high-lift, high concentration, remote pulp conveying equipment, and the security of equipment, operability, maintenance requirement are all very high.This pump is the key equipment in the induction system, and the quality of its working condition directly has influence on the conveying of ore pulp amount and normally carrying out of mineral processing production.The fault of oil isolation then may have influence on whole production line and stop, thereby oil isolation pump has very important effect aborning.Such as Fig. 1, existing replacing piston cup method of operating is with piston rod 4 and the piston head 2 whole crossheads 5 that screw out, and releases outside the piston cylinder 3 again, assemble again whole precession crosshead 5, because of new leather cup interference, the long 180mm of precession crosshead 5 screw threads, and it is bad to reverse the position, so that dismounting is all very difficult, wastes time and energy, easy damaged leather cup 1, such method of operating are whole turnover, beat by force, the replacing time is long, needs personnel many, and repair quality is difficult to guarantee, very easily do over again, impact is produced.
Summary of the invention
The purpose of this utility model is to provide a kind of the needs that piston rod and the whole rapid tool change that screws out crosshead of piston head under the prerequisite of not damaging leather cup, are realized the quick-replaceable installation.
For achieving the above object, the utility model is taked following technical scheme, a kind of oil isolation pump piston cup quick replacement device is made of guide pin bushing and portal, it is characterized in that, the bellmouth that described guide pin bushing endoporus is made of the taper hole face, the small end head of guide pin bushing bellmouth is provided with a mouth, and described portal is made of column, crossbeam, base and jack pad assembly, and two columns upper end is equipped with crossbeam, the lower end is equipped with base, and the crossbeam stage casing is fixed with jack pad assembly.
Use this device, can screw out piston rod, piston cylinder cylinder diameter 250mm utilize coupling box to split out nut, owing to can easily take out the piston head assembly, after more renewing leather cup, the piston head assembly is put into guide pin bushing be enclosed within on the piston-cylinder mouth, at guide pin bushing door shaped stent is installed again, the good jack of frame, piston body is headed in the piston cylinder, and upper jack panel gets final product.
The utility model has the advantages that, when leather cup is installed, need not the integral demounting piston head, can finish the replacing of leather cup, can guarantee installation quality, shorten the replacing time.

The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples, referring to Fig. 2 to Fig. 5, a kind of oil isolation pump piston cup quick replacement device, consisted of by guide pin bushing 6 and portal 7, it is characterized in that, the bellmouth that described guide pin bushing 6 endoporus are made of taper hole face 61, the small end head of guide pin bushing 6 bellmouths is provided with a mouth 62, described portal 7 is made of column 71, crossbeam 72, base 73 and jack pad assembly 74, two columns, 71 upper ends are equipped with crossbeam 72, the lower end is equipped with base 73, and crossbeam 72 stage casings are fixed with jack pad assembly 74.
Embodiment:A kind of oil isolation pump piston cup quick replacement device, consisted of by guide pin bushing 6 and portal 7, the endoporus of guide pin bushing 6 is bellmouth, the small end head that the taper hole face 61 of bellmouth consists of is provided with a mouth 62, the small end head that the taper hole face 61 of bellmouth consists of equates with the internal diameter of piston-cylinder 3, portal 7 is made of column 71, crossbeam 72, base 73 and jack pad assembly 74, two columns, 71 upper ends are installed with crossbeam 72, the lower end is equipped with base 73, crossbeam 72 stage casings are fixed with jack pad assembly 74, and jack pad assembly 74 is equipped with jack.
Install when changing leather cup 1, piston rod 4 on the crosshead 5 needn't screw out, guide pin bushing 6 is placed on 3 mouthfuls of the piston-cylinders, the piston head 2 that installs leather cup 1 is placed the large termination of guide pin bushing 6 bellmouths, with jack piston head 2 is headed in the piston cylinder 3 again, piston head 2 is inserted in piston rod 4, tightens clamp nut and split pin, gets final product.
