Abstract

The utility model discloses a chronograph which relates to the machinery electric appliances. The utility model is suitable for recording the operating time of some movable type operation electromechanical products of cranes, concrete mixers, road rollers, loaders, bulldozers, etc. to obtain the purpose of evaluating the operational reliability of the product. The utility model is composed of a clock circuit [6], an electromagnetic counter [5], etc. The utility model is connected with the electromechanical products [7] in parallel together to be connected to a joyswitch [4]. When the joyswitch [4] is operated, the electromechanical products [7] move, and the utility model also starts to record the operation time of the electromechanical products. The utility model has the advantages of accurate timing, convenient operation, low cost, easy maintenance, etc. The utility model saves a large quantity of workload for evaluating operating reliability of the electromechanical products.

Description

Chronograph

The utility model relates to the mechanical electric apparatus product, is applicable to the working time of some mobile operation electronic product such as record crane, excavator, concrete mixer, street roller, dozer, to reach the purpose of the functional reliability of evaluating this series products.

On the existing various motor vehicle mileometer is housed all, it provides the data of various vehicle ' total kilometrages for people, and also maintenance, maintenance period and the vehicle reliability degree for motor vehicles provides convenience.But, present some mobile operation electronic product, as the workload of various long playing electronic products such as crane, excavator, dozer, shovel loader, the street roller register that all has no time, can only lean on its working time of manual record, therefore when evaluating the functional reliability of this series products, need pay very big workload.

The purpose of this utility model provides a kind of a kind of time regulator of being made up of clock circuit (6) and message register (5) that is used to write down some electronic product activity duration.

Existing accompanying drawings is as follows:

Fig. 1 is a practical circuit of the present utility model.

7906 circuit of three-terminal voltage-stabilizing integrated (1) connect with power supply among the figure, and to 6 volts of power supplys of 555 circuit chips (2) supply, 555 circuit chips (2) the generation cycle is 36 * 10 to power supply by 7906 circuit of three-terminal voltage-stabilizing integrated (1) ⁿThe square wave of (n=0 or-1), this square wave is after the tripod output of 555 circuit chips (2), through protective resistance R ₃(3) send into transistor 3AK9 (4), square wave drives electromagnetic registration device (5) record square wave quantity by transistor 3AK9 (4).When n=0, the decimal place that the last double figures of electromagnetic registration device is hour, when n=-1, the decimal place that three at the end of electromagnetic registration device is hour.

Fig. 2 is that the utility model connects figure with electronic product.

The utility model of being made up of message register (5) and clock circuit (6) among the figure connects with master cock (8) after electronic product (7) parallel connection, the utility model be made up of message register (5) and clock circuit (6) with master cock (8) control and the starting operation of electronic product (7).

Fig. 3 is the fundamental diagram that the utility model is applied in truck-mounted crane.

(10) are three connections for breather pipe among the figure, (12) be the truck-mounted crane accumulator, (13) be the power takeoff manipulating cylinder, (14) be air tank, the utility model of being made up of electromagnetic counter (5) and clock circuit (6) is connected on the pneumatic switch (11) of truck-mounted crane, when handling power takeoff manipulation air valve (9), truck-mounted crane is just in running order, simultaneously, the utility model also enters duty, the working time of opening entry truck-mounted crane.

The utlity model has and clock accurately, easy to use, cheap, keep in repair advantages such as easy, for the functional reliability of evaluation electronic product has been saved a large amount of workloads.
