Abstract
The utility model provides a bulb cross-flow type runner blade dismounting device. The bulb cross-flow type runner blade dismounting device comprises a jack, a fixing rod, a full-thread fixing head and a connector. The jack is in screw joint with one end of the fixing rod, the other end of the fixing rod is connected with the connector, and the end, close to the jack, of the fixing rod is provided with the full-thread fixing head. According to the scheme, the full-thread fixing head is fixed in a bolt hole in the blade end and connected with the connector through an oil pump, the oil pump is started to enable the jack to increase the pressure, and then a shaft can be separated from a shaft sleeve. All parts can be subjected to even force by evenly distributing a plurality of jacks, and the jacks can stably get out of components to be dismounted.
Description
Technical field
The utility model relates to a kind of runner bucket and splits out device, refers to that especially a kind of scaled bulb tubular runner bucket splits out device.
Background technology
In the bulb tubular hydraulic generating set of hydroelectric power plant, 8 M100 bolts and pivotally connected for runner bucket, symmetrical uniform 4 M100 torque pin, blade axle journal and wheel hub axle sleeve fit clearance are 0.10～0.16mm.
The device of existing dismounting turbine blade is the screw bolt jackscrew of two M100*500, by symmetrical two turbine blades and pivotally connected bolt hole, with the symmetrical both sides of special spanner, synchronously tightens jackscrew, and blade is ejected from wheel hub.Because blade axle journal coordinates closely with wheel hub axle sleeve, blade and pivot torque pin fit clearance (0.06～0.10mm) are less, both sides inhomogeneous blade-side, pivot side moment of torsion pin-and-hole and the torque pin coaxiality deviation of very easily making of exerting oneself is large, cause blade-side moment of torsion pin-and-hole and torque pin or pivot side pin-and-hole and torque pin jam, if not as good as adjusting axiality, will be stuck, pin-and-hole or torque pin are caused to damage, also may make blade screw thread damage.In addition, and existing blade splits out device heaviness, can only use manpower, time and effort consuming, inefficiency.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of scaled bulb tubular runner bucket that can efficiently quickly and safely blade be split out and splits out device.
For solving the problems of the technologies described above, embodiment of the present utility model provides a kind of scaled bulb tubular runner bucket to split out device, comprise jack, fixed bar, full thread gland and connector, one end of described jack and described fixed bar is spirally connected, the other end of described fixed bar is connected with described connector, and the nearly very heavy top of described fixed bar is provided with full thread gland.
Wherein, in described fixed bar, be provided with oilhole, described oilhole is communicated with the oilhole sealing of described jack.
The beneficial effect of technique scheme of the present utility model is as follows:
In such scheme, by full thread gland being fixed on to blade end bolt hole place, use oil pump to be connected with connector, start oil pump jack is boosted, can make axle and axle sleeve separate; Can realize each portion by uniform multiple jack stressed evenly, steadily exit dismounting parts.
Accompanying drawing explanation
Fig. 1 is the structural representation that the utility model embodiment scaled bulb tubular runner bucket splits out device.

The specific embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearer, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model splits out device heaviness for existing blade, and the problem of fragile pin-and-hole or torque pin provides a kind of scaled bulb tubular runner bucket to split out device.
As shown in Figure 1, a kind of scaled bulb tubular runner bucket of embodiment of the present utility model splits out device, comprise jack 1, fixed bar 2, full thread gland 3 and connector 5, described jack 1 is spirally connected by internal thread 4 and one end of described fixed bar 2, the other end of described fixed bar 2 is connected with described connector 5, described connector is used for connecting electric oil pump or hand oil pump, and the nearly very heavy top of described fixed bar 2 is provided with full thread gland 3.
Wherein, in described fixed bar 1, be provided with oilhole 6, described oilhole 6 is communicated with the oilhole sealing of described jack 1, for jack 1 work provides hydraulic channel.
The utility model embodiment use procedure is as follows:
In the blade bolt hole that packs two or more jack 1 of the present utility model into symmetry or be evenly arranged, two or more jack are screwed into same depth with spanner, make full thread gland 3 be fixed on blade end, with electric oil pump or hand oil pump, by one two, be in charge of or be in charge of more respectively and be connected with two or more connectors 5 of the present utility model, start oil pump pressurization, it is consistent that two or more jack pressures remain, the each portion of blade surrounding is synchronously exited, torque pin exits pin-and-hole stably, avoid torque pin to block pin-and-hole and caused parts damages, extend parts service life, reduce workload, increase work efficiency.
The above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; do not departing under the prerequisite of principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a scaled bulb tubular runner bucket splits out device, it is characterized in that, comprise jack, fixed bar, full thread gland and connector, one end of described jack and described fixed bar is spirally connected, the other end of described fixed bar is connected with described connector, and the nearly very heavy top of described fixed bar is provided with full thread gland.
