Изобретение относитс  к испытательной технике, в частности к способам испытани  узлов грузоподъемных манлин статическим нагружением.The invention relates to a testing technique, in particular, to methods for testing static mannin load-lifting units.

Известны способы испытани  узлов грузоподъемных машин статическим нагружением с Применением грузоудерживающих, например кабин лифтов, и динамометрических устройств , неподвижных опор и рабочих лебедок. При этом рабочую лебедку используют дл  создани  реактивного усили .Methods are known for testing static load-bearing machines with the use of load-carrying, for example, elevator cars and dynamometric devices, fixed supports and working winches. In this case, a working winch is used to create a reactive force.

Известные способы трудоемки и требуют больших финансовых затрат.Known methods are laborious and costly.

Цель изобретени  - ускорение и удешевление испытаний.The purpose of the invention is acceleration and cheapening of tests.

Дл  этого грузоподъемное устройство присоедин ют к неподвижной опоре посредством механической св зи и рабочей лебедкой создают необходимое испытательное усилие.For this, the lifting device is attached to the fixed support by means of a mechanical connection and the working winch creates the necessary test force.

На чертеже схематически показано устройство дл  осуществлени  предлагаемого способа .The drawing schematically shows a device for carrying out the proposed method.

Кабину / лифта присоедин ют к неподвижной опоре 2 посредством механической св зи 3 с динамометром (на чертеже не показано). Последний присоединен к регистрирую цему устройству 4 и дистанционному указателю 5.The cab / elevator is connected to the fixed support 2 by means of a mechanical connection 3 with a dynamometer (not shown). The latter is connected to register device 4 and remote pointer 5.

Кабина соединена канатом 6 с рабочей лебедкой 7.The cabin is connected by a rope 6 with a working winch 7.

Необходимое испытательное усилие создают за счет враш,ени  маховика на быстроходном валу редуктора при выключенном тормозе .The required test force is created by the vras, flywheel on the high-speed shaft of the gearbox with the brake off.

При достижении заданного испытательного усили , регистрирующее устройство 4 подает сигнал на дистанционный указатель.Upon reaching the specified test force, the recording device 4 sends a signal to the remote pointer.

Дл  обеспечени  заданной выдержки включают тормоз. Машина считаетс  выдержавшей статические испытани , если дистанционный указатель в течение выдержки не изменит своих показаний.To ensure the specified shutter speed, the brake is activated. The machine is considered to have passed the static test if the remote pointer does not change its readings during the exposure.

Предмет изобретени Subject invention

Способ испытани  узлов грузоподъемных машин статическим нагружением с применением грузоудерживающих, например кабин лифтов, и динамометрических устройств, ненодвижных опор и рабочих лебедок, отличающийс  тем, что, с целью ускорени  и удешевлени  испытаний, грузоудерживающее устройство присоедин ют к неподвижной опоре посредством механической св зи и рабочей лебедкой создают необходимое испытательное усилие.The method of testing the load-lifting machines by static loading using load-carrying facilities, such as elevator cars, and dynamometric devices, non-fixed supports and working winches, characterized in that, in order to speed up and reduce the cost of testing, the load-holding device is attached to the fixed support by means of a mechanical connection winch create the necessary test force.
