Abstract

The utility model discloses a centrifugal machine of concrete tubular products, which comprises a main body support, wherein a first transmission assembly and at least two driven wheels are arranged on the main body support, the first transmission assembly which is connected with a driving unit is provided with at least two driving wheels, and belts which can support and drive pipe steel moulds to rotate are wrapped on the driving wheels and the driven wheels corresponding to the driving wheels. The centrifugal machine of concrete tubular products enables the pipe steel moulds not to be directly contacted with the driving wheels and the driven wheels, and greatly reduces abrasion of the pipe steel moulds, the driving wheels and the driven wheels. Besides, the flexibility of the belts enables the belts to absorb the impact force generated during the rotation of the pipe steel moulds, accordingly the vibration and the noise caused by the impact force are greatly reduced, and the danger of burst or fly-out of the driving wheels is avoided. In addition, the smoothness of the surfaces of produced pipe fittings is high, the thickness of pipe walls is even, and quality problems of invisible cracks and the like do not occur.

Description

The tubular goods centrifuge of concrete

Technical field

The utility model relates to a kind of building materials manufacturing machine, the tubular goods centrifuge of particularly a kind of concrete.

Background technology

Development along with the domestic construction industry, the demand of the tubular product of concrete is increasing, the enterprise that makes the pipe of concrete series products constantly enlarges, quantity also increases in succession, and centrifuge be annular prestressed (from stress) concurrent of producing various centrifugal formings, from the capital equipment of stress pressure pipe and concrete tubular pile.When the centrifuge that uses is worked at present, pass through transmission component by main motor, give final drive shaft with transmission of power, final drive shaft passes through shaft coupling, with transmission of power to main shaft and driving wheel, by the friction between driving wheel and the pipe punching block turning moment is passed to the pipe punching block again, opposite side at the pipe punching block also is provided with the running wheel that is mainly used in the stay pipe punching block, the pipe punching block is arranged between driving wheel and the running wheel, the pipe punching block is produced rotatablely move, make the concrete material in the pipe punching block finish centrifugal forming.

But, in said structure, manage punching block, reaching the driving wheel and the running wheel that directly contact with the pipe punching block all is made of metal, and the pipe punching block adds that the weight concrete in the pipe punching block is very big, in high speed rotating, the pipe punching block is all very big with friction and impact between two kinds of wheels, produce the vibrations of jumping up and down when causing pipe die to rotate, and constantly and two-wheeled form lasting bump, thereby produced the very big noise that thunders, multiple devices move simultaneously, produce noise and just be difficult to make the people to bear more, noise is having a strong impact on direct labor's health, also affects the contiguous resident's of enterprise's periphery normal life; And, very big friction and impact cause that the wearing and tearing of parts are bigger, make the service life of parts low, enterprise is big to the maintenance cost of manufacturing equipment, the frequent part at each position of exchange device more, product quality is stable inadequately, build-up of pressure is produced in the expansion of enterprise, and direct labor and contiguous resident's resentment sound are continuous, and the complaint of enterprise is increased; Also can produce quality problems to produced pipe fitting, make pipe fitting produce stealthy crackle, local location has loose phenomenon, and tube wall thickness is inhomogeneous, and pipe fitting surface smooth is affected etc.; Impact and vibrations even can cause that driving wheel is quick-fried and take turns or fly out, thereby bring great danger to producers.

Summary of the invention

In order to overcome the deficiencies in the prior art, the utility model provides a kind of and shakes little and noise is low, safety, the tubular goods centrifuge of concrete that maintenance cost is low.

The technical scheme that its technical problem that solves the utility model adopts is:

The tubular goods centrifuge of concrete, it is characterized in that: comprise main body rack, main body rack is provided with first transmission component and at least two driven pulleys, be connected with driver element on first transmission component, first transmission component is provided with at least two driving wheels, driving wheel and with the corresponding driven pulley of this driving wheel on be arranged with can holding and drive the belt that the pipe punching block rotates.

As optimal way of the present utility model, described first transmission component comprises that some are arranged at power transmission shaft on the main body rack by bearing, and above-mentioned power transmission shaft is connected by shaft coupling.

Described driver element is arranged at the centre position of first transmission component, and two outputs of this driver element are connected with power transmission shaft respectively.

Described driver element is a variable-frequency motor.

Be provided with second supporting component between described main body rack and driven pulley, second supporting component comprises that the driven shaft and this driven shaft that are relatively arranged on two holders on the main body rack and are arranged between two holders fixedly connected with holder, and described driven pulley is connected with driven shaft by bearing.

Described main body rack is provided with slotted hole, and described holder is connected with main body rack by the connection securing member that is arranged in this slotted hole.

The beneficial effects of the utility model are: the utility model is provided with the driving wheel and the driven pulley that can rotate on main body rack, drives the pipe punching block and rotates at driving wheel and with belt on the corresponding driven pulley of this driving wheel by winding.Thereby avoiding managing punching block directly contacts with driving wheel and driven pulley, the wearing and tearing of pipe punching block, driving wheel and driven pulley have not only been reduced, and the impulsive force that can the absorption tube punching block in rotation, produces of the flexibility of belt, thereby greatly reduced the vibrations and the noise that cause by impact, avoided causing the quick-fried danger of taking turns or flying out of driving wheel, and, the smoothness height on the pipe fitting surface of producing, pipe thickness is even, does not have quality problems such as stealthy crackle.

In sum, the utility model not only shakes little and noise is low but also degree of safety is high, long service life, and maintenance cost is low.
