Description
Technical field
The utility model relates to a kind of hydraulic spanner lifting apparatus.
Background technology
At present, the permanent magnet direct-drive electromotor of MW class, its rotor connecting bolt is BIG SIZE BOLTS and separate unit bolt quantity is more, hydraulic wrench need to be used to fasten, but spanner itself heavier (6.5kg), and lift instrument without auxiliary, operator are when fastening stator connecting bolt, hydraulic spanner need to be lifted for a long time, be easily caused fatigue, thus cause quality problems and potential safety hazard.
Summary of the invention
The utility model proposes a kind of hydraulic spanner lifting apparatus, play purpose and aim to solve the problem that the arm Fatigue problem operating employee in stator connecting bolt fastener cycle, solve a series of safety problems and the quality problems caused due to fatigue simultaneously.
Technical solution of the present utility model: hydraulic spanner lifting apparatus, its structure includes sliding sleeve, sliding sleeve connects two support bars by M10 × 40 bolt, slide bar is connected with the center of sliding sleeve by guide rail transmission, spring is set on slide bar, slide bar end connects one end of B connecting rod, and the other end of B connecting rod connects one end of A connecting rod, and the other end of A connecting rod connects bracket.
Preferably, described B connecting rod is hinged with slide bar, only has relative rotary freedom between B connecting rod and slide bar.
Preferably, described A connecting rod and B rod hinge connection, only there is between A connecting rod with B connecting rod relative rotary freedom.
Preferably, described A connecting rod is hinged with bracket, only has rotary freedom between A connecting rod and bracket.
Preferably, the geomery of described bracket is corresponding with the overall size of hydraulic spanner.
Preferably, the length of described A connecting rod and B connecting rod adapts to the middle flange hole position of electric machine main shaft.
Preferably, only there is between described slide bar and sliding sleeve vertical degree of freedom and rotary freedom.
Preferably, the spacing of described support bar adapts to the position, hole of generator shaft base.
Advantage of the present utility model: this hydraulic spanner lifting apparatus uses the frame for movement optimized, 1/4 delineation axle bolt can be fastened by once mounting.During bolt fastens, utilize spring force to replace manually lifting power, spring the elastic force produced just can lift the parts of more than spring.Solve the fatigue problem during fastening generator unit stator connecting bolt, eliminate potential safety hazard, decrease a bit manipulation employee simultaneously, improve personnel's utilization rate, separate unit electromotor bolt tightens and more originally shortens 20 minutes, improves product quality and production efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of hydraulic spanner lifting apparatus.
In figure 1 is A connecting rod, 2 is B connecting rod, 3 is slide bar, 4 is support bar, 5 is sliding sleeve, 6 is bracket, 7 is spring, 8 is M10x40 bolt.
Detailed description of the invention
Below in conjunction with embodiment and detailed description of the invention, this utility model is described in further detail.
As shown in Figure 1, hydraulic spanner lifting apparatus, its structure includes sliding sleeve 5, sliding sleeve 5 connects two support bars 4 by M10 × 40 bolt 8, slide bar 3 is connected with the center of sliding sleeve 5 by guide rail transmission, and slide bar 3 sets spring 7, and slide bar 3 end connects one end of B connecting rod 2, the other end of B connecting rod 2 connects one end of A connecting rod 1, and the other end of A connecting rod 1 connects bracket 6.
Described B connecting rod 2 is hinged with slide bar 3, only has relative rotary freedom between B connecting rod 2 and slide bar 3.
Described A connecting rod 1 is hinged with B connecting rod 2, only has relative rotary freedom between A connecting rod 1 and B connecting rod 2.
Described A connecting rod 1 is hinged with bracket 6, only has rotary freedom between A connecting rod 1 and bracket 6.
The geomery of described bracket 6 is corresponding with the overall size of hydraulic spanner, as the pallet of hydraulic spanner.
The length of described A connecting rod 1 and B connecting rod 2 adapts to the middle flange hole position of electric machine main shaft, and a combination thereof length can fasten by the bolt of 1/4 circle on centering flange.
Between described slide bar 3 and sliding sleeve 5, only there is vertical degree of freedom and rotary freedom.
The spacing of described support bar 4 adapts to the position, hole of generator shaft base.
In this frock, spring force lifts power as a kind of mechanical force for the offer of whole mechanism, by calculating connecting rod 1, connecting rod 2, bracket 5 and the gravity of hydraulic spanner, the required elastic force provided of spring-compressed is provided, the decrement of spring is gone out again by the Size calculation of mechanism, comprehensive elastic force and decrement, determine the specifications and models of spring.
According to above structure, during operation, the support bar 4 of this device, sliding sleeve 5, spring 6 and slide bar 3 are taken dead axle, choose two screwed holes identical with two support bar spacing bottom dead axle, support bar 4 is inserted fixing, then fit on connecting rod and bracket 6.
During operation, one hand buttresses slide bar 3 top, slide bar 3 is down pressed, behind the position vacateing hydraulic spanner, spanner is placed on bracket 6, then slide bar 3 is loosened, hydraulic spanner is held up by device by the elastic force of spring 7, adjust the position of spanner and bolt simultaneously, the sleeve on spanner is inserted in bolt head, just can carry out bolt and tighten work.
Above-described is only preferred implementation of the present utility model; it should be pointed out that, for the person of ordinary skill of the art, on the premise of creating design without departing from this utility model; can also make some deformation and improvement, these broadly fall into protection domain of the present utility model.
