Balance weight installs utensil additional online

Technical field

The utility model is related to a kind of generating set appurtenance, and more particularly to a kind of balance weight installs utensil additional online.

Background technology

Generator amature is particularly important core component in generator unit, and balance weight is to ensure that unit operation is steady One of vital part.When generating set is in startup and shutdown, generator bearing shell vibration is bigger than normal, and balance weight is installed at rotor-end Counterweight by a small margin can be carried out in the counterweight tank in portion, so that the problem of reaching and solve vibration.

As shown in figure 3, balance weight 3 need to be arranged in the counterweight tank 5 in generator jiggering shield 4, in the top of balance weight 3 Center is provided with the balance pipe 31 of shape of threads, and the flat recess installed is provided with the end face of the balance weight 3 of the both sides of balance pipe 31 32., must due to generator to wheel close to the big end cap in vapour end when needing to install the balance weight at generator clutch position additional Must first take generator jiggering shield 4 apart, it is then hand-held that the alignment of balance weight 3 is put into counterweight tank 5, reuse a word and rise and will put down The block 3 that weighs is screwed in counterweight tank 5, finally assembles generator jiggering shield 4.Its shortcoming is：First, the volume of motor jiggering shield is huge Greatly, again, to tear process open relatively complicated for its peace, causes working strength big；2nd, generating set is shut down suddenly after long-play, its The high temperature and high pressure gas produced during operation are collected in body, it is impossible to discharge clean immediately, internal body temperature may be up to several Baidu or so, operating environment and its severe alreadys exceed the limit that human body is born, can not overhauled at once substantially, causes inspection Repair time growth.

Utility model content

The purpose of this utility model is that provide a kind of balance weight that need not take generator jiggering shield apart installs additional online Utensil.

This balance weight that the utility model is provided installs utensil additional online, including locating rod and slip cap are mounted in the locating rod The loop bar in outside, the locating rod is threadedly coupled with the balance pipe of balance weight, and loop bar is slided to be driven in the flat recess of embedded balance weight Dynamic balance weight rotates around the axle center of locating rod.

Be provided with the thread segment that is engaged with balance pipe on balance weight in the bottom of the locating rod, be provided with loop bar bottom with The projection that flat recess is engaged on balance weight.

It is connected, is arranged with the top of the locating rod for coordinating with spanner to enable the utility model and peace to tear instrument open Clamping face.

It is connected to enable the utility model and peace to tear instrument open, is arranged with the top of the loop bar for coordinating with spanner Operating surface.

For convenience of being by hand directly threadedly coupled locating rod of the present utility model with balance weight, adopted at the top of the locating rod With T-shaped.

For convenience of by hand directly screwing in balance weight of the present utility model in counterweight tank, using T-shaped at the top of the loop bar.

The locating rod is using the multi-segment structure being threadedly coupled.

For convenience of processing of the present utility model, the loop bar is fastenedly connected by sleeve and two end cap and constituted, and locating rod is passed through The end cap of top is set with sleeve gap, and thread segment is threadedly coupled through the end cap of lower section with the balance pipe of balance weight, and projection is set End cap both sides in lower section.

Locating rod and loop bar that the utility model is socketed using gap, need to only take apart small vexed on the outer oily shelves of jiggering shield Plate, is threadedly coupled by locating rod with balance weight, and hand-holdable probe into balance weight in jiggering shield is directed at clutch balance weight position Put, rotational positioning bar band dynamic balance weight is screwed into counterweight tank；It is connected by loop bar with balance weight bumps, rotation loop bar drives balance Block is further torqued into the fastening installation that balance weight is completed in counterweight tank, it is not necessary to take barring gear shield apart, working strength is small；No Need staff directly facing the high temperature and high pressure gas in unit, security is good；Without being installed additional again after waiting unit radiating, locate The reason time is short.The utility model is simple in construction, operates flexible and convenient, and strong adaptability, cost is low, substantially increases generating set and exists Line installs the efficiency of balance weight additional.

Brief description of the drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation that Figure 1A-A locate.

Fig. 3 is the structural representation of the utility model use state.

Embodiment

This balance weight of the utility model is can be seen that from Fig. 1 to Fig. 3 and installs utensil, including locating rod 1 and loop bar additional online 2, loop bar 2 is sleeved on the outside of locating rod 1 and can slided up and down along locating rod 1, is provided with and balance weight in the bottom axle center of locating rod 1 The thread segment 11 that 3 upper center balance pipes 31 are engaged, is provided with and the phase of 3 top both sides flat recess of balance weight 32 in the bottom of loop bar 2 The projection 21 of cooperation, locating rod 1 is threadedly coupled controllable balance weight 3 with balance pipe 31 by thread segment 11 and inserts generator jiggering In shield 4, rotational positioning bar 1 can be screwed in counterweight tank 5 with dynamic balance weight 3, and it is embedding that loop bar 2 is snapped down to projection 21 in locating rod 1 Enter in flat recess 32, further counterweight tank 5 is screwed in by rotating the axle center rotation that loop bar 2 can be with dynamic balance weight 3 around locating rod 1 It is interior.

It can be seen that from Fig. 1 and Fig. 3 and be provided with symmetrical clamping face 12, clamping face at the top of the utility model locating rod 1 12 are interconnected to six side's shapes, and symmetrical operating surface 22, spanner clamping clamping face 12 or operating surface 22 are provided with the top of loop bar 2 Driving locating rod 1 or loop bar 2 rotate respectively.

In the utility model, the top of locating rod 1 can also use T-shaped, and the top of loop bar 2 can also be double using T-shaped Hand, which is held, T-shaped can drive locating rod 1 or loop bar 2 to rotate respectively.

It will be seen from figure 1 that in the utility model, because loop bar 2 operating surface 22 or T-shaped must be positioned at dynamic panel The outside of car shield 4 could realize rotation, so that the entire length to locating rod 1 has most short requirement, when the end cap of rotor tip When having two, its spacing belongs to particular value, the spacing be slightly smaller than locating rod 1 and balance weight 3 minimum length and, therefore locating rod 1 need to be using the multi-segment structure being threadedly coupled, when the cylindrical section of balance weight 3 is stretched into counterweight tank 5, you can locating rod 1 is assembled Integrally.

Loop bar 2 of the present utility model is can be seen that from Fig. 1 to Fig. 3 group is fastenedly connected by sleeve 23 and upper/lower terminal lid 24 Into locating rod 1 is set with through the end cap 24 of top with the gap of sleeve 23, end cap 24 and balance weight 3 of the thread segment 11 through lower section Balance pipe 31 be threadedly coupled, the both sides of end cap 24 that are positioned below of projection 21.

In the utility model, loop bar 2 can also use monolithic construction.
