Description
Technical field
When relating to the slow test of bridge type crane, the utility model as the water tank type test mass piece of test load, is particularly useful for the slow test of hydraulic power plant's (station) bridge type crane.
Background technology
The work of the allowing loading of bridge type crane (also claiming bridge type crane or bridge type overhead traveling crane) is tens of tons at least, hundreds of tons at most, the large-scale bridge type crane that hydraulic power plant's (station) uses is generally more than 400 tons, the general nearly kiloton of the work of allowing loading of the bridge type crane of ultra-large type genset power house, some is even more than kiloton.
The safety work order of relevant industries has been made clear and definite inspection and test mass standard to the bridge type crane in new installation and life cycle.Stipulated new installation or should carry out slow test through the bridge type crane of overhaul, allow the work loading with 1.25 times, suspend 10 minutes, check situation and the parts of whole hoisting device, and measurement framework deflection degree; Stipulated that general routine test allows that with 1.1 times the work loading carries out the slow test of 10 minutes; Also stipulated the cycle of routine test simultaneously, carried out once, carried out once in every 3 years that are of little use in namely commonly used 1 year.
In the existing slow test of bridge type crane, adopt cement (concrete) test mass piece or ironcasting test mass piece as the loading load of slow test, single-piece cement or ironcasting test mass piece are generally tens tons or tens of ton, the hanging basket that some cement test mass pieces or ironcasting test mass piece will be housed during test hangs approximately 10 centimeters, ground, namely the bridge type crane is carried out related check, detection.Adopt cement or ironcasting test mass piece as the defective that slow test loads load to be: one, after completing slow test, because the test mass piece general assembly (TW) that is used for slow test is large, hundreds of tons, even go up cement or the ironcasting test mass piece of kiloton, the lifting transhipment workload when lifting is stored and again tested is large; Its two, make hundreds of ton, even go up cement test mass piece or the ironcasting test mass piece of kiloton, need a large amount of material of consumption, cost is high; Its three, store hundreds of ton, even go up the cement of kiloton or the shared place of ironcasting test mass piece is large, be not easy to store, especially when centralized stores, load to storage ground is large, and the storage that satisfies load need be set specially, increases the construction cost of storage.Use cement test mass piece or ironcasting test mass piece as the existing defective of slow test load, perplex normally carrying out of bridge type crane slow test always, even cause slow test to be difficult to carry out, have a strong impact on the safety in operation of bridge type crane.
The utility model content
Deficiency for the prior art existence, the purpose of this utility model is to provide the water tank type test mass piece of a kind of bridge type crane slow test, during test, to add the interior water of water tank as the slow test load, after test is completed, the water in emptying water tank, water tank is lightweight, lifting transhipment and storage are convenient in the supporting member detachment dismounting of water tank type test mass piece, are convenient to reuse.
The technical solution of the utility model comprises referring to Fig. 1 to Fig. 3:
In the slow test process, described water tank 1 is positioned at the inner chamber of assembly type scaffold 2, and the freeing port 1b of water tank 1 is equipped with draining valve or is equipped with sealed plunger, and the water as the slow test load is housed in water tank 1; Assembly type scaffold 2 also is used for except water tank 1 being carried out spacing and rising protective action the slow test load that supporting loads on its top.
Be further:
Described water tank 1 casing is lower bevel-type structure (referring to Fig. 1) or vertical wall-like structure (referring to Fig. 4);
The overlappable formula of described a plurality of described water tank for slow test is collected and storage, when the tank box that is used for slow test is lower bevel-type structure, utilize the lower bevel-type design feature of tank box to carry out stacked collection, the storage of a plurality of water tanks, as shown in Figure 6; When the tank box that is used for slow test is vertical wall-like structure, will be arranged to several other different physical dimension of level for the water tank of slow test, the water tank that physical dimension is little is placed in the large water tank of physical dimension and carries out stacked collection, storage, as shown in Figure 7.
Use the utility model as the operating process of slow test load to be, one, at first the assembly type scaffold 2 after assembling hangs on the interior bottom load bearing cross beam of slow test hanging basket, they are two years old, after draining valve being installed on the freeing port 1b of tank bottom wall or water tank side wall lower ends section or being inserted sealed plunger, empty water tank is hung in the inner chamber of assembly type scaffold, then add water as the slow test load in water tank, add the operation of namely completing a water tank type test mass piece after the water operation is completed.Operation successively in this way, and can being ordered in by the modes of many of one decks and multilayer setting in the test hanging basket, and place the transition crossbeam between the upper strata of water tank type test mass piece and lower floor, after the test load that reaches setting, can begin to carry out slow test.
After test was completed, the draining valve on opening water discharge mouth 1b, by the draining valve draining, or took out the interior sealed plunger of osculum 1b in an orderly manner in an orderly manner, by osculum 1b draining, and empty water tank hung out in the slow test hanging basket.The water that each water tank is discharged is by other component collection, discharging.
Compared with the prior art, the technique effect that the utlity model has is:
1, each member and the stiffening plate 6 due to assembly type scaffold 1 is modular demountable structure, can dismantle by part, and storage is convenient in classification after dismounting, and it is little to take the place of storage, and is convenient to the delivery vehicle transhipment and reuses.
2, can a plurality of stacked collections and storage due to the tank box of lower bevel-type structure, the water tank of vertical wall type structure of container, can realize by the mode of being arranged to other different physical dimension of several grades a plurality of stacked collections and storage, the stacked collection of a plurality of water tanks and storage occupied ground are little.
3, due to the basic load of adopting the water that adds to water tank as test, empty water tank after draining is lightweight, therefore needs the hardware general assembly (TW) of storage light, and is little to the floor loading of storing the place, need not to arrange specially storage, can reduce the construction cost of storage.
4, the hardware general assembly (TW) due to need storages is light, and the empty water tank after draining can the stacked collection of a plurality of water tanks, can reduce the lifting workload of transhipment, is convenient to the delivery vehicle transhipment, is convenient to reuse.
5, owing to adding water in water tank as the slow test load, therefore the consumption of required member is few, with existing cement test mass piece or ironcasting test mass piece ratio, can greatly reduce consumptive material and reduce manufacturing cost, when especially hydraulic power plant's (station) uses the utility model, have more fetch water convenient, the easy characteristics of operation.
The technique effect that the utility model has is conducive to promote normally carrying out of bridge type crane slow test, especially the slow test of hydraulic power plant's (station) bridge type crane.
Other technique effect that the utlity model has will further illustrate in embodiment.
