Description
Technical field
The utility model belongs to flight-line maintenance technical field, and 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 to fail, and the sealing effectiveness of water is deteriorated, and need to change check valve 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, is dismounted its nut by impulsive force;Check valve flange works as dismounting close to rolling-mill housing
It is limited in space that sledgehammer is swung during fixing nut near to rolling-mill housing, percussion power deficiency, dismounting is wasted time and energy, easily made
Into during dismounting, nut is not torn open not get off, and the phenomenon revealed in use occur in pretightning force deficiency, adpting flange during assembling.
Deficiency, develops in the industry a variety of fulcrum bearings for being easy to centering for more than, such as Chinese patent CN 204339661
Utility model provides a kind of percussion spanner, including:Spanner cutting ferrule (10), it is provided with the inwall of spanner cutting ferrule (10) limited
Block (11).Plexor member (20), plexor member (20) include tapping bar (21) and tap 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 and Wrench of the prior art while make
The problem of used time operating difficulties.Its patent weak point is that handle is oversize, can not rotate use.For another Chinese patent CN
102407502 tap spanner the invention discloses a kind of, and the percussion spanner includes tapping wrench body, the percussion wrench body
One end also includes and percussion formed with polygonal-shaped openings, the shape of the opening and the form fit of fastener, the percussion spanner
The be hinged impact component of the other end of wrench main body, the impact component include:Connects hinge, the hinge axis of the connects hinge hang down
Directly in the rotational plane for tapping wrench body;Impact bar, one end are connected to connects hinge;Impact block, it is slidably mounted in punching
Hit on bar;Block piece, stop impact block to prevent impact block from being slid 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.

Circular arc is bent into, also may be used from square, rectangle, circular section shape, its extension bar in good time according to the size of the dynamics of percussion
According to the in good time Curved from straight or with angle of the situation of the withdrawal space, 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 are welded with spherical pieces, used as beating point.
Preferably, the semicircle arc key its be shaped as semicircular arc and rectangular combination, 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, plays positioning
Effect, rectangle bulk central part are machined with positioning hole, and positioning screw spherical head coordinates its positioning.
Preferably, the positioning screw its be shaped as step, head section is spherical, and two sections are optical axis, and three sections are full wire spiral shell
Bar, endpiece are hexagon.45# steel modifier treatment.
The utility model can be in the situation nut of narrow space, and meets requirement;It is simple in construction, integral rigidity
By force, extension bar is unlikely to deform;Extension bar coordinates with tapping spanner semi arch, and increase taps lifting surface area, can prevent percussion process
Middle extension bar slips injury human body and equipment with tapping spanner;It is simple to operate, mitigate labor strength and economize labor time.
