RU2654841C2 - Method for determining technical safety of carrying out lubricating and filling operation while servicing vehicles - Google Patents

Abstract

FIELD: transportation.

SUBSTANCE: while determining the technical safety of carrying out lubricating and filling operations, double gloves are used: first ones - internal, water resistant; second ones - exterior, hygroscopic. They are weighed before and after each operation. The received material weight is considered while defining the technical safety of carrying out each lubricating and filling operation when servicing a vehicle.

EFFECT: improving the work performance safety while determining the technical safety of carrying out lubricating and filling operations while servicing vehicles.

Description

The invention relates to the maintenance of motor vehicles, in particular to methods for determining the technical safety of technical maintenance of cars, tractors, combines and other self-propelled machines.

A known method for determining the environmental safety of the performance of lubricating and filling operations during maintenance of machines [1].

The main disadvantage of this method is that it is suitable for assessing the environmental safety of lubricating and filling operations.

The closest technical solution, selected as a prototype, is a method for determining the technical safety of the performance of lubricating and filling operations when servicing machines. This method is as follows. The material used is fixed on gloves and sleeves that are used once during each operation. In this case, gloves and sleeves are weighed before and after this operation. Then assess the availability of material on gloves and armlets by finding the difference in their mass. The weight of the material on gloves and sleeves determines the technical safety of each operation during maintenance of the machine [2].

The disadvantage of this method is that in its practical implementation, the experimenter (operator) can be exposed to fuel and lubricants due to their contact with hands, which is unacceptable according to labor protection requirements.

The objective of the invention: to improve the safety of work when determining the technical safety of lubricating and refueling operations performed during maintenance of the machine.

The essence of the invention lies in the fact that when determining the technical safety of the performance of lubricating and filling operations, double gloves are used: the first are internal, waterproof; the second is external, hygroscopic. They are weighed before and after each operation. The resulting mass of material is taken into account when determining the technical safety of each lubricant-filling operation during maintenance of the machine. The use of double gloves, some of which are waterproof, prevents materials from falling onto the operator’s hands, which improves the safety of work when determining the technical safety of lubricating and refueling operations during machine maintenance.

The method can be carried out, for example, in garage conditions as follows. The operator, when preparing for work, puts on himself sleeves and double gloves: the first - internal, waterproof; the second is external, hygroscopic. All this is pre-weighed. The first operation is carried out from the list of lubricating and refueling operations, for example, draining oil from the crankcase. Oil is fixed on hygroscopic gloves, and waterproof gloves do not let it through. As a result, oil does not get on the skin of the hands. After completing this operation, the operator removes the sleeves and gloves. They are weighed again. Then assess the availability of material (in this case, motor oil) on the sleeves and gloves according to the formula

Для этого полученную массу материала Q_Mi сопоставляют с допускаемым значением. Аналогичным образом определяют техническую безопасность других смазочно-заправочных операций. При этом всякий раз используют чистые нарукавники и перчатки.where Q _Mi is the mass of material on the sleeves and gloves when performing the i-th operation,

- the mass of sleeves and gloves before and after the i-th operation. The material mass Q _Mi determined determines the technical safety of this operation. For this, the resulting mass of material Q _{Mi is} compared with the permissible value. Similarly determine the technical safety of other lubricating and filling operations. At the same time, clean sleeves and gloves are used every time.

Thus, the proposed method allows to improve the safety of work when determining the technical safety of the performance of lubricating and filling operations performed during maintenance of the machine.
