Description
Technical field
The invention belongs to flight-line maintenance technical field, more particularly to a kind of extension bar taps spanner.
Background technology
At present, during wide and heavy plate mill Rolling Production, each rolling pass needs to carry out water under high pressure to hot steel billet in advance
De-scaling is handled.The pressure of water under high pressure is up to 280bar, and the frequent injection of water under high pressure causes the spring in line check valve valve body to return
Elastic force declines, and causes failure, and the sealing effectiveness of water is deteriorated, and check valve need to be changed in time；When dismounting check valve flange fixing nut
Instrument used in general is to tap spanner, first will hit against spanner working end and is placed in check valve flange fixing nut and block, so
The percussion end of spanner is tapped with sledgehammer afterwards, its nut is dismounted by impulsive force；Check valve flange works as dismounting close to rolling-mill housing
Sledgehammer is swung during fixing nut near to rolling-mill housing limited in space, percussion power is not enough, dismounting is wasted time and energy, easily made
Into during dismounting, nut is not torn open not get off, and pretightning force is not enough during assembling, and the phenomenon revealed in use occurs in adpting flange.
It is not enough for more than, a variety of fulcrum bearings for being easy to centering, such as Chinese patent CN 204339661 are developed in the industry
Utility model provides a kind of percussion spanner, including：It is provided with spanner cutting ferrule (10), the inwall of spanner cutting ferrule (10) limited
Block (11).Plexor member (20), plexor member (20) includes tapping bar (21) and taps cap (22).Tap cap (22) rotationally
It is arranged in spanner cutting ferrule (10), taps cap (22) and be connected to the first end for tapping bar (21) and have and restricted volume (11)
The limited block (221) of cooperation.The second end for tapping bar (21) is provided with the connector coordinated with screw cap sleeve or ut socket
(211).The technical solution of the utility model can efficiently solve percussion instrument of the prior art and Wrench while making
The problem of used time operating difficulties.Its patent weak point is that handle is oversize, it is impossible to which rotation is used.For another Chinese patent CN
102407502 tap spanner the invention discloses one kind, and the percussion spanner includes tapping wrench body, the percussion wrench body
One end is formed with polygonal-shaped openings, the shape of the opening and the form fit of fastener, and the percussion spanner also includes and percussion
The impact component that the other end of wrench main body is hinged, the impact component includes：Connects hinge, the hinge axis of the connects hinge hangs down
The straight rotational plane in percussion wrench body；Impact bar, one end is connected to connects hinge；Impact block, is slidably mounted in punching
Hit on bar；Block piece, stops impact block to prevent that impact block from sliding from impact bar.The percussion spanner carries impact function,
It is easy to carry, and reduce to the requirement using space.Its patent weak point be impact component can not flexural deformation, can only
Vertical to tap, hinge axis is easily bent deformation when tapping.
The content of the invention
A kind of extension bar that the problem of purpose of the present invention is and existed for more than is designed taps spanner, and its is simple in construction,
It is easy to use, during dismounting high-pressure water descaling check valve flange fixing nut, it can effectively solve to dismount limited space system, tap
Power is not enough, the problem of wasting time and energy, so as to mitigate labor strength and economize labor time.Technical solution of the present invention is as follows：
A kind of extension bar taps spanner, includes percussion spanner, taps spanner and is provided with working end, tail end, plum blossom-shaped circular hole, upper semi-circle
Arc and lower half circular arc, it is characterised in that：Coordinate to be provided with extension bar, the curved shape of extension bar, extension bar with percussion spanner and be provided with
Through hole, one end of extension bar is taps end, and the other end of extension bar is provided with screw, coordinates with screw and be provided with positioning screw and locking
Semicircle arc key is additionally provided with nut, the through hole of extension bar, semicircle arc key is made up of arc key semi arch with rectangle face；Tap spanner
Working end passes through the through hole of extension bar, and positioning screw is assembled together and loaded the spiral shell of the through hole upper end of extension bar with locking nut
Kong Zhong, positioning screw will hit against spanner by semicircle arc key and with locking nut with lengthening rod locking.Under in described through hole
Face is provided with tapping the through hole semi arch that the lower half circular arc of spanner matches.The percussion end of described extension bar is that semicircle is spherical.
The arc key semi arch of semicircle arc key with tap spanner tail end upper half circular arc match, be provided with the rectangle face of semicircle arc key with
The corresponding positioning hole of positioning screw, the spherical of positioning screw head section is headed into the positioning hole of semicircle arc key.The extension bar
Cross sectional shape be cross.
It is preferred that, it is described to tap the plum blossom-shaped that spanner working end is 12 deciles, in order to be conveniently adjusted dismounting corner
Angle, it is two halves arc-shaped up and down to tap end, it is therefore an objective to which lifting surface area when increase is tapped, afterbody has strip backstop, width
It is slightly wide, it is therefore an objective to which that extension bar is difficult abjection, material 40Cr steel solid forgings when tapping.
It is preferred that, the extension bar cross sectional shape is cross, and rigidity is strong, overall deformation when can prevent from tapping.Also can root
Square, rectangle, circular section shape are selected in good time according to the size of the dynamics of percussion, and its extension bar is bent into circular arc, also may be used
According to the selection straight of the situation of the withdrawal space in good time or the Curved with angle, its other end is machined with strip hole slot, strip
One side of hole slot is semicircular arc, and second half is vertical processing.The top of strip hole slot processes a screw, for fastening semicircle
Arc key, its other end is welded with spherical pieces, is used as beating point.
It is preferred that, it is shaped as semicircular arc and rectangular combination to the semicircle arc key, with striking after semicircular arc installation
The semicircular arc for hitting spanner is engaged, and is played the role of positioning, and rectangle bulk can be slided in the strip hole slot of extension bar, play positioning
Effect, rectangle bulk central part is machined with positioning hole, and positioning screw spherical head coordinates it to position.
It is preferred that, it is shaped as step to the positioning screw, and head section is spherical, and two sections are optical axis, and three sections are full silk spiral shell
Bar, endpiece is hexagon.45# steel modifier treatment.
The present invention can narrow space situation nut, and meet use requirement；Simple in construction, integral rigidity is strong, extension bar
It is unlikely to deform；Extension bar coordinates with tapping spanner semi arch, and increase taps lifting surface area, can prevent during tapping extension bar with
Tap spanner and slip injury human body and equipment；It is simple to operate, mitigate labor strength and economize labor time.
