Description

A kind of core mould vibrating bar that is used for core mould vibrating machine

Technical field

The utility model relates to a kind of core mould vibrating bar that is used for core mould vibrating machine, can be used for producing reinforced concrete sewer pipe, belongs to the core mould vibrating machine technical field.

Background technology

Core mould vibrating bar is the heart component of core mould vibrating machine, and by regulating electric machine frequency, the vibration that produces controllable frequency drives the outer mold vibration, makes the concrete compaction in the mould, reaches the manufacturing requirements of product.

As shown in Figure 1, be German Zu Bulin core mould vibrating machine core mould vibrating bar structural representation, form by latch segment 1, motor 2, eccentric block 3, column 4, platform 5, the every side of column 4 three sides is fixed with six motors 2 of polyphone, totally 18 motors 2 drive the vibration that eccentric block 3 rotations produce controllable frequency, drive the outer mold vibration again, make the mould inner concrete closely knit, its shortcoming is:

Since plug at the mould inside center of product, when motor was operated at full capacity, 18 heats that motor produced can't fully distribute, temperature inside is very high, causes working conditions of motor to worsen, and shortens its service life;

2. because vibration source is to be driven synchronously by hitch bar by 18 motors, if thereby wherein a certain or several motors break down, will cause whole core mould vibrating machine work to stop, accident rate and maintenance rate height;

3. one of the every damage of motor all will be from external import, and domestic still do not have a replaceable product, and every of expense is about 10,000 yuan, and only will spend about 500,000 yuan every year on this, the maintenance cost height;

4. keep in repair length consuming time, the maintenance difficulties height.Because accessory all needs from external import, therefore wait for that the time of accessory is longer, the normal scheduling of production of the company that influences, and also the complex structure of German plug, dismounting formality are loaded down with trivial details, cause the maintenance difficulties increase.And domestic like product does not also have.

Summary of the invention

The purpose of this utility model provides a kind of reduction accident rate and maintenance rate, reduces maintenance cost and cost, the core mould vibrating bar that is used for core mould vibrating machine of enhancing productivity.

For realizing above purpose, the technical solution of the utility model provides a kind of core mould vibrating bar that is used for core mould vibrating machine, it is characterized in that, be made up of pressure head cap, eccentric block device, central shaft, sleeve pipe, latch segment, frame and motor, at least two eccentric block device are connected in the sleeve pipe by central shaft, and sleeve pipe connects by latch segment, pressure head cap is located at the upper end of sleeve pipe, sleeve pipe is vertical on the frame, is provided with at least one motor in the bottom of frame, and motor is connected with central shaft.

The utility model produces centrifugal force according to eccentric wheel and causes the principle vibrated, form by at least two group eccentric block device polyphone, drive by at least one motor under the base, three groups of eccentric block device that are fixed on central shaft produce the controllable frequency vibration, central shaft is connected with mould by axle sleeve, cause the mould vibration, make the mould inner concrete closely knit, reach the manufacturing requirements of product.

Advantage of the present utility model is:

1. motor places under the outer base of column, and working conditions of motor is good, has prolonged service life, has reduced accident rate, and maintenance of motor is easy;

2. vibration is by the driven by motor eccentric block device, thereby compares with German plug and to have significantly reduced number of motors, has reduced accident and maintenance incidence;

3. greatly reduce maintenance cost;

4. because accessory all is by domestic processing, the time of therefore changing accessory is shorter, can not influence ordinary production, and mandrel structure is simple, and the dismounting formality is simple, and maintenance difficulties reduces.
