Abstract
The utility model relate to nuclear power station maintenance, install and other industry and civilian dynamo-electric overhaul of the equipments, install time use professional tool.When using existing fork spanner to screw bolt or nut for solving, fork spanner is easily from landing bolt to be screwed or nut, cause motor device disassembly and assembly time long, the inefficient problem of dismounting, the utility model proposes a kind of fork spanner, this fork spanner comprises wrench body and baffle plate, and this baffle plate and gland parallel with the spanner of described wrench body is pulled on mouth in described wrench body, in use, described baffle plate covers head or the nut of bolt to be screwed.Bolt or nut is screwed at this fork spanner of use, fork spanner can be stoped along bolt to be screwed or the downward landing of nut, only need carry out a centering operation and can complete torquing operations, reduce the degree of wear of bolt or nut, service life extends, improve the efficiency screwing bolt or nut, and then improve the efficiency of dismounting electromechanical equipment.
Description
Technical field
The utility model relate to nuclear power station maintenance, install and other industry and civilian dynamo-electric overhaul of the equipments, install time use professional tool, particularly relate to the bolt on electromechanical equipment, nut class workpiece carries out dismounting time fork spanner.
Background technology
Electromechanical equipment is being assembled, is installing and in unloading process, need to screw a large amount of bolts, nut class workpiece.When using existing fork spanner to screw it, operating personnel need first to carry out the operation of counterpart centering to be stuck on bolt to be screwed or nut by the mouth of pulling of fork spanner to fork spanner, then just can screw.But in the process of screwing, because operating personnel operate shakiness, the contact surface between fork spanner and bolt to be screwed or nut reduces, and treats even mutually and screws bolt or nut run-off the straight, and then cause fork spanner from landing bolt to be screwed or nut.Like this, for completing the disassemble and assemble work of bolt or nut, operating personnel need carry out the operation of counterpart centering to fork spanner again, and even repeatedly repeat this operation, and then cause the time lengthening of dismounting electromechanical equipment, dismounting efficiency is low; And repeatedly repeat to carry out the operation of counterpart centering to fork spanner, also can treat screwing bolt or nut causes wearing and tearing, cause shorten the service life of bolt or nut.
Utility model content
When using existing fork spanner to screw bolt or nut for solving, fork spanner is easily from landing bolt to be screwed or nut, cause motor device disassembly and assembly time long, the inefficient problem of dismounting, the utility model proposes a kind of fork spanner, this fork spanner comprises wrench body and baffle plate, and this baffle plate and gland parallel with the spanner of described wrench body is pulled on mouth in described wrench body, in use, described baffle plate covers head or the nut of bolt to be screwed.When using this fork spanner to screw bolt or nut, because baffle plate covers head or the nut of bolt to be screwed, even if operating personnel operate shakiness, also fork spanner can be stoped along bolt to be screwed or the downward landing of nut by baffle plate, namely only need treat the bolt screwed or nut to carry out a centering operation and can complete torquing operations, thus reduce the degree of wear of bolt or nut, service life extends, improve the efficiency screwing bolt or nut, and then improve the efficiency of dismounting electromechanical equipment.
Preferably, described baffle plate is flexibly connected by connecting axle with described wrench body, and described baffle plate can rotate around described connecting axle.Further, described connecting axle is bolt or bearing pin.Like this, in use, first baffle plate can be turned on and the mouth of pulling of fork spanner is exposed, can see when carrying out the operation of counterpart centering to make operating personnel and pull mouth, facilitate counterpart centering, and after counterpart centering has operated, then baffle plate is gone to pull on mouth and cover and pull mouth, thus make baffle plate gland on the head or nut of bolt to be screwed, to avoid fork spanner from landing bolt to be screwed or nut.
Preferably, the neck of described wrench body is provided with connecting through hole, and described connecting axle is arranged in this connecting through hole.Like this, the connecting portion of baffle plate and wrench body is arranged on the neck of wrench body, both can not have an impact to the intensity of spanner, baffle plate also can not be made to waste because length is excessive and make material.
Preferably, described baffle plate is provided with screw rod positioning through hole.Like this, when using this fork spanner to screw the nut be set on screw rod, screw rod can be made to pass from this screw rod positioning through hole, both the torquing operations to the nut be set on screw rod can once have been completed, can being positioned fork spanner by screw rod again, avoiding fork spanner through pulling mouth from landing nut to be screwed.
The utility model fork spanner arranges baffle plate in wrench body, head or the nut of bolt to be screwed is covered to use baffle plate when screwing bolt or nut, thus avoid fork spanner because operating personnel operate shakiness from landing bolt to be screwed or nut, decrease counterpart centering number of operations, shorten counterpart centering to expend time in, what improve bolt or nut screws efficiency, and then improve the dismounting efficiency of electromechanical equipment, also reduce the operation of counterpart centering simultaneously and treat the wearing and tearing screwing bolt or nut, extend the service life of bolt or nut.Baffle plate arranging screw rod positioning through hole, so that when screwing the nut be set on screw rod, screw rod being passed from screw rod positioning through hole, thus screw rod is positioned fork spanner, avoiding fork spanner through pulling mouth from treating landing screw on nut.
Accompanying drawing explanation
Fig. 1 is the schematic top plan view of the utility model fork spanner;
The assembling schematic diagram that Fig. 2 is the fork spanner shown in Fig. 1.
Detailed description of the invention
As illustrated in fig. 1 and 2, the utility model fork spanner comprises wrench body 1 and baffle plate 2, this baffle plate 2 is positioned at spanner 11 place of wrench body 1, and this baffle plate 2 is parallel with spanner 11 and gland is being pulled on mouth 111, to cover head or the nut of bolt to be screwed in use.When using this fork spanner to screw bolt or nut, the mouth of pulling of this fork spanner is being stuck in after on the head or nut of the bolt screwed by operating personnel, on the head making baffle plate 2 be pressed in bolt to be screwed or nut.Like this, when screwing bolt or nut, on the head being pressed in bolt to be screwed due to baffle plate 2 or nut, even if operating personnel operate shakiness, baffle plate also can be utilized to stop fork spanner along bolt to be screwed or the downward landing of nut.Preferably, baffle plate 2 is provided with screw rod positioning through hole 21.Like this, when using this fork spanner to screw the nut be set on screw rod, screw rod passes from this screw rod positioning through hole 21, can position fork spanner, thus avoids fork spanner through pulling mouthful opening part from treating landing screw on nut.
As shown in Figure 2, baffle plate 2 is flexibly connected by connecting axle 4 with wrench body 1, and baffle plate 2 can rotate around connecting axle 4.Like this, fork spanner is being pulled before mouth 111 is stuck on bolt to be screwed or nut by operating personnel, rotatable baffle plate 2 exposes will pull mouth 111, convenient operation personnel carry out the operation of counterpart centering, and after counterpart centering has operated, then baffle plate 2 is gone to pull above mouth 111 to push down bolt to be screwed or nut.When making this fork spanner, bolt or bearing pin can be adopted to connect baffle plate 2 and wrench body 1 as connecting axle 4.Preferably, the neck of wrench body 1 is provided with connecting through hole 12, and connecting axle 4 is arranged in this connecting through hole 12.Like this, baffle plate 2 is arranged on the neck of wrench body 1 with the connecting portion of wrench body 1, both can not have an impact to the intensity of spanner 11, baffle plate 2 also can not be made to waste material because length is excessive.
