Abstract

The utility model discloses the combining loading and unloading test bed of a U-shaped vehicle and a fixed hydraulic elevator, consisting of a U-shaped vehicle, a fixed hydraulic elevator, a test bed and a pallet. The U-shaped vehicle adopts hand-push type and is convenient and easy for moving back and forth without the troubles caused by charging electric forklift truck and the noise and smog pollution of the oil forklift truck, thus conforming to the requirements of environment protection. By adopting the fixed hydraulic elevator loading and unloading machine, the test bed is parallel with the ground and the elevator can stop at the position which is parallel with the ground, and the ground is even, thus narrowing the air and the ground of a testing station is avoided and the working environment of the testing station is not influenced. The stiffness of the pallet and the test bed is very good with a stable base, which is safe and reliable and has no interference to the test. Compared with the original hoisting method, the hoisting time is saved for two times with high working efficiency. The utility model has no requirement for the height of testing room and the structure of girder, therefore, the cost is much lower than the other schemes and the effect is obvious.

Description

The hydraulic lifting experiment table

Technical field

The utility model relates to generator unit testing station testing table, especially relates to multistation testing station testing table.

Background technology

Modern generator unit multistation testing station's testing table work-handling technology has following several form: 1, driving, single-beam hang or electric block lifting mode, on test testing table position, room, fix or the combined type test platform, driving or electric block are housed on the platform, by driving or electric block workpiece are hung onto on the testing table and test.Big, the big beam strength height of this technical requirement test roof, room height makes testing station's investment greatly.Another problem is that to be furnished with the test platform of form difference, different sizes on the ground above ground level, makes test space, room, ground narrower and small, influences the environment of experiment centre.Also having a problem is that this technical work efficient is too low.2, the electronic or hand pallet truck mode of band small-sized hydraulic or screw rod leg, this technology is that unit is lifted on the flat-bed trailer, flat-bed trailer leaves (pushing away) and enters to test the room to the testing table position, and hydraulic pressure (screw rod) leg stretches out support on the ground, holds up flat-bed trailer and unit and experimentizes.This technical matters is that hydraulic pressure (screw rod) leg support plate car causes the experimental basis shakiness, and poor reliability influences the authenticity that unit is tested, and is particularly bigger to unit vibratory test influence.3, storage battery or oily mechanomotive force fork truck transport the lifting mode, and this technology is furnished with the overhead test platform of form difference, different sizes at place, test testing table position, room, utilizes storage battery or oily mechanomotive force fork truck that the unit handling is tested to test platform.This technical matters is that ground is furnished with the overhead test platform of form difference, different sizes, make ground narrower and small, fork truck influences the environment of work efficiency and experiment centre into and out of difficulty, and multistation carries out the increase of unit testing requirements fork truck quantity simultaneously and causes and throw appearance and strengthen.Another problem is that battery fork lift truck exists the charging trouble, to producing certain influence is arranged normally.There are environmental protection problems such as locomotive noise, waste gas, smog pollution in oil mechanomotive force fork truck.

Summary of the invention

The purpose of this utility model is to provide a kind of ordinary test room building structure that both can satisfy, can not make space, ground narrow and small, influence the testing table of testing station's environment, and this testing table base fixed, reliability height, can not produce the unit test and disturb, there is not environmental pollution yet, can also reduce investment, improve work efficiency, to satisfy the need of work of modernized multistation unit testing station.

The technical solution of the utility model is: a kind of hydraulic lifting experiment table, this device comprises U-shaped ground rail car, pallet, fixed hydraulic lifting table, test platform, fixed hydraulic lifting table both sides are provided with test platform, test platform is provided with the ground rail, the ground U-shaped ground rail car of can walking on the rail, U-shaped ground rail car is furnished with the ground rail wheel that bearing is housed, and U-shaped ground rail car is provided with pallet.

Advantage of the present utility model is: the U-shaped car adopts hand propelled, and advance and retreat are convenient, and are free and relaxed.No battery fork lift truck charging trouble or oily machine fork truck noise, smog pollution, compliance with environmental protection requirements.Adopt fixed hydraulic hoistable platform loading and unloading unit, test platform is equal in ground, and hoistable platform can stop and the mean place mutually in ground, and ground is smooth, can not cause to test that the room is aerial, ground is narrow and small, influences testing station's working environment.The hoistable platform system adopts four-bar mechanism, and single hydraulic cylinder drives, and lifting is steady, and is safe and reliable.Pallet and test platform rigidity are fabulous, and the basis steadily, and is safe and reliable, noiseless to testing.More original lifting mode is saved lifting time, work efficiency height twice.To test room height of house, big girder construction no requirement (NR).Cost is significantly less than other scheme, and effect is obvious.With the 6 station testing stations that implemented is example, than adopt driving, single-beam hangs or the electric block mode is saved fund more than 30%.Save fund more than 50% than adopting storage battery or oily mechanomotive force fork truck to transport the lifting mode
