Abstract

The utility model relates to a concrete drill hole core taking machine, which comprises a gasoline engine elevating mechanism and a vertical axle, wherein a gear box is arranged at the output end of the gasoline engine, the output axle of the gasoline engine and the input axle of the gear box are assembled coaxially, the output axle of the gear box is connected with the vertical axle through a belt. Because a first level gear box is arranged at the output axle of the gasoline engine of the utility model, the deceleration duty of a next two stage belt transmission is greatly lightened. The diameters of the partial input wheels and the output wheels of the belt transmission is more optimized and justified compared with an outside measurement, the transmission efficiency is enhanced magnificently, the outside measurement of the complete machine is compact and reasonable, and the actual demand of the site operation is met, thus having a good use value. In addition, a reduction gearbox adopts a chain drive and directly is connected with the engine, the structure is simple, the size is compact; the elevating mechanism adopts a rolling motion screw-pair, thereby the operation is portable and labor saving.

Description

Concrete boring corning machine

Technical field

The utility model relates to a kind of building and construction machinery, relates in particular to a kind of concrete boring corning machine tool.

Background technology

At present, have a kind ofly to be the vertical shaft type petrol engine, be equipped with the transmission of one-level band, directly drive vertical main shaft and rotate with gasoline engine driven concrete boring corning machine.Because have only the one-level band to rotate, speed ratio is big, makes that the vertical shaft runner is excessive, causes transmission efficiency low not compact with structure, and use value is not high.In addition, its elevating mechanism is common lead screw transmission, and relatively effort operates.

The utility model content

At above-mentioned situation, the purpose of this utility model is to provide a kind of concrete boring corning machine, to improve transmission efficiency, optimizes drive mechanism.

For achieving the above object, the technical solution of the utility model is to have adopted a kind of concrete boring corning machine, comprise petrol engine, elevating mechanism and vertical shaft, petrolic output is equipped with a gearbox, the power shaft coaxial line assembling of petrolic output shaft and gearbox, the output shaft of gearbox links to each other with vertical shaft by belt transmission.

In the described gearbox is linked transmission.

The belt transmission of corning machine is the double reduction transmission.

Described elevating mechanism is the rolling screw auxiliary structure.

Because the utility model is provided with the one-level gearbox at the petrol engine output, make the deceleration task of follow-up second belt transmission greatly alleviate, belt transmission is partly imported, the radius of output wheel when appearance and size optimize more and rationally, improved transmission efficiency well, the machine shape size is compact and reasonable more, satisfied the actual needs of site operation, good practical value has been arranged.In addition, reduction box adopt chain drive and with the motor direct connection, simple in structure, compact dimensions; Elevating mechanism adopts rolling screw pair, and it is light, laborsaving to operate.
