Description
Technical field
This utility model belongs to power plant's field of tool.
Background technology
Two sections of main shafts of thermal power plant's vertical circulation water pump are that by box coupling connection even box coupling is an entirety set
Cylinder is coordinated by flat key and realizes the shaft coupling that two axles connect, and has that radial dimension is little, simple in construction, low cost and other advantages.But dress
Weight must be reached the main shaft of 1 ton when tearing open to axially move, very inconvenient.After particularly water circulating pump runs an overhaul life
Equipment disintegrate, because sleeve and axle use interference fits, add the erosion of rust and impurity, with sledgehammer, sleeve dismounting is abnormal the most tired
Difficult.As dynamics is excessive, dynamics is uneven, hits asymmetric operational error of Denging, also shaft coupling and axle can be caused damage.
Summary of the invention
The purpose of this utility model is the combination by hydraulic jack and special purpose device, water circulating pump box coupling
Sleeve, the fluid pressure type water circulating pump box coupling provision for disengagement ejected symmetrically and evenly.
The junction of axle first of the present utility model and axle second is installed by locating ring, and is inserted in box coupling, axle
First bottom has end cap, box coupling bottom to be placed in the draw-in groove of chuck, and chuck bottom withstands on and adds on long column, hydraulic jack
Big piston withstands on and adds long column bottom, and the base of hydraulic jack is placed on the end cap of axle first bottom.Chuck is inserted with scale, scale
Bottom is arranged on end cap.
This utility model one fluid pressure type water circulating pump box coupling provision for disengagement, simple in construction, easy to operate, province
Power, safety height, good stability.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Detailed description of the invention
The junction of axle first 9 of the present utility model and axle second 8 is installed by locating ring 6, and is inserted in box coupling 7
In, axle first 9 bottom has end cap 1, box coupling 7 bottom to be placed in the draw-in groove of chuck 4, and chuck 4 bottom withstands on and adds on long column 3,
The big piston of hydraulic jack 2 withstands on and adds long column 3 bottom, and the base of hydraulic jack 2 is placed on axle first 9 bottom end cap 1.At card
Being inserted with scale 5 on dish 4, scale 5 bottom is arranged on end cap 1.Hydraulic jack 2 uses two, and is arranged on same axis
On.
This utility model one fluid pressure type water circulating pump box coupling provision for disengagement, force application apparatus is hydraulic jack,
Effect is to impose the least power at jack handle, according to Pascal's law, can produce the biggest on jack top act part
Power, by chuck, promotes sleeve to move: auxiliary device is chuck, and effect is that the active force of jack is transmitted sleeve uniformly,
Make sleeve and axle generation relative movement.
As it can be seen, this utility model one fluid pressure type water circulating pump box coupling provision for disengagement includes: end cap 1, liquid
Press jack 2, add long column 3, chuck 4, scale 5, locating ring 6, box coupling 7, axle second 8, end cap 9.
A. with steel plate processing " chuck 4 " of 20mm, the internal diameter of chuck is more than the diameter of axle 2mm of axle second；External diameter is more than axle first axle
Shoulders diameter of axle 5cm；" chuck 4 " point two semicircular, centre is connected with.Gusset is strengthened in the welding of back, chuck both sides.Left and right is right
Claim the turning one concave surface more than jack stopper head diameter 2mm；
B. processing " adding long column 3 " with φ 60mm round steel, each lengthening column length 5CM, a facing one is more than jack
The concave surface of stopper head diameter 2mm, the facing one boss more than jack stopper head diameter 2mm；
C. making of φ 7.5mm round steel " scale 5 " of 60cm length, scale uses threaded, is screwed on Magnetic gauge stand；
D. by two 50T " hydraulic jack 2 ", bottom is placed on after adding parallels on the shaft shoulder (end cap) of " axle first 1 ".
Operation principle:
This utility model one fluid pressure type water circulating pump box coupling provision for disengagement operation principle is: utilize hydraulic jack
The feature on top " art is good for strength ", by " hydraulic jack 2 " handle is imposed the least power, lifts on " hydraulic jack 2 " top
Produce the biggest active force on part, by " chuck 4 ", promote " box coupling 7 " to move forward, make " box coupling 7 "
Leave installation site, it is achieved the dismounting of two axles.Uniformly move by " scale 5 " monitoring sleeve lateral symmetry, prevent because sleeve moves
Crooked stuck.
Its operational approach, as shown in structural representation:
A. a pair semicircular chuck is buckled and be stuck in box coupling root；
B. by two 50T hydraulic jack, bottom is placed on after adding parallels on the shaft shoulder of axle first, and plunger is lifted on top should be directed at chuck
Concave surface:
C. carrying magnetic gauge stand scale, absorption is on the shaft shoulder；
D. checking that the parts of jack are with or without damage, if flexibly, as found, there is crackle in screw mandrel, nut, should forbid making
With.Should check that its piston valve is the best for oil-pressure jack, the oil mass in fuel tank is the most sufficient, once finds leakage of oil
Or parts fault, maintenance should be changed immediately.After Zheng Chang, jacking hydraulic jack, by the scale of both sides, the sleeve of monitoring both sides
Should be symmetrical uniform mobile, forbid crooked.
E. the jacking of raising the head of hydraulic jack top is to markings, or the 3/4 of depth pistion, stop operation, by hydraulic jack
Pressure release, top of raising the head on top is installed one piece and is added long column ", operate hydraulic jack, continue jacking, repeatable operation, until sleeve joins
Axial organ reaches removed position.
F. pull down locating ring, separate two axles.
This utility model one fluid pressure type water circulating pump box coupling provision for disengagement, simple in construction, easy to operate, province
Power, safety height, good stability, have good promotional value.
