The eccentric shaft is arranged in each vibrating case. One end of the eccentric shaft extends out of the case body, and the end portion of the eccentric shaft is connected with one belt pulley. The number of the variable-frequency and variable-speed motors is two, and an output end of each variable-frequency and variable-speed motor is in transmission connection with a rotating shaft of the eccentric shaft matched with the output end. A bearing hole is drilled in each case box. A rolling bearing is installed in the bearing hole. The number of the eccentric shafts is two, and each eccentric shaft is installed on the rolling bearing of each case body. The two variable-frequency and variable-speed motors are respectively connected with the eccentric shafts through the V belts, and respectively drive the eccentric shafts to rotate. The two eccentric shafts of the vibrating cases rotate towards the opposite directions. According to the block machine vibrating device, the disconnect-type vibrating cases are adopted, the block machine vibrating device is simple in structure, convenient to maintain and large in vibration quantity, and the eccentric shafts in the vibrating cases are not interfered to each other.

Description

A kind of vibration device of building block former

Technical field

The utility model relates to a kind of vibrating device, relates in particular to a kind of vibration device of building block former, belongs to the block machine mechanical equipment technical field.

Background technology

The vibrating device of block machine is existing a variety of at present, but mostly be vibration casing the inside two or more eccentric shafts that distributing, but have the following disadvantages: at first, main eccentric shaft drives by the synchromesh gear engagement and rotates from eccentric shaft, because vibratory impulse power is large, break of gear tooth occurs and lost efficacy in synchromesh gear easily.Secondly, one of them of two eccentric shafts breaks down, and can cause another to be interfered under running at a high speed.Distance between the three, two eccentric shaft is subject to the constraint that synchromesh gear connects, and is difficult to make vibratory output to promote.The 4th, the vibrating bin volume is large, and is comparatively heavy, is not easy to maintenance.

The utility model content

For the weak point in solving the problems of the technologies described above, the utility model provides mutually noninterfere between a kind of simple in structure, easy to maintenance, vibration casing inner eccentric shaft, vibration device of building block former that vibratory output is large.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of vibration device of building block former, and the involving vibrations platform, it also comprises frequency control motor, V band, belt pulley and vibrating bin;

Vibrating bin is comprised of casing, eccentric shaft and rolling bearing; Vibrating bin is two, by the corresponding parallel below of being fixed in shaking platform of four bolts; The in-built eccentric shaft that is equipped with of vibrating bin; One end of eccentric shaft stretches out outside the casing, and connects belt pulley in the end;

Frequency control motor is two, and the turning cylinder of the eccentric shaft that the output of each frequency control motor is mated is in transmission connection; Be processed with dead eye on the casing, rolling bearing is installed in the dead eye.

Eccentric shaft is two, is installed in respectively on the rolling bearing on the casing.

A two changes frequency buncher links to each other and drives respectively eccentric shaft by the V band with eccentric shaft respectively and rotates; Two interior eccentric shafts of vibrating bin rotate in the opposite direction.

Advantage of the present utility model is: adopt the Separated vibration case, motor drives respectively two eccentric shaft backward rotation in two vibrating bins, can guarantee to vibrate required exciting force, make the vibration of forming machine shaking platform and moulding box vertical orientation, simultaneously mutually noninterfere between the vibrating bin can prolong service life of whole vibrating device; Can apart from each other between two vibrating bins, not only can vibrate more stably, and improve vibratory output, vibration is evenly distributed in whole platen scope, so that concrete rapid shaping within a short period of time, cement fully liquefies, and has guaranteed the packing of building block; Do not use synchromesh gear in the vibrating device, the probability that breaks down in the vibration processes reduces; The vibrating bin volume is little, simple in structure, easy to operate, easy to maintenance.

Description of drawings

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is structural representation of the present utility model.

Fig. 2 is the structural representation of the utility model vibrating bin.

Fig. 3 is the structural representation of the utility model eccentric shaft.

Among the figure: 1. shaking platform; 2. frequency control motor; 3.V band; 4. belt pulley; 5. casing; 6. eccentric shaft; 7. rolling bearing.

The specific embodiment

As Fig. 1-shown in, the utility model mainly by shaking platform 1, frequency control motor 2, V be with 3, belt pulley 4 and vibrating bin form.

Shown in Fig. 2-3, vibrating bin mainly is comprised of casing 5, eccentric shaft 6 and rolling bearing 7.Casing 5 two ends are processed with dead eye, casing 5 can be that integrally casting forms, also can form with Plate Welding, the size of casing 5 determines at 5 four angles of casing bolt hole is arranged respectively by the size of shaking platform 1, is fixed together by bolt and shaking platform 1.Rolling bearing 7 is installed in the dead eye, generally selects deep groove ball bearing.Eccentric shaft 6 is installed on the rolling bearing 7, and eccentric shaft 6 is to process with round steel, and eccentric throw is selected according to the size of required vibratory output.

Casing 5 is two as shown in Figure 1, the symmetrical below that is installed in shaking platform 1, and an end of eccentric shaft 6 stretches out outside the casing 5, and the end of eccentric shaft 6 is connecting belt pulley 4.Frequency control motor 2 is power resources of whole vibrating device, is installed in respectively the both sides of vibrating bin, and the nameplate parameter of frequency control motor 2 can be selected according to the size of required vibratory output.Be with 3 to be connected by two V between frequency control motor 2 and the eccentric shaft 6, V is with 3 to be specially adapted to shock and vibration and high-power transmission.

The course of work of the present utility model is as follows: when filling up concrete in the moulding box of block machine and being placed on the supporting plate on the shaking platform 1, beginning Vibration on Start-up device, frequency control motor 2 work are rotated, be with 3 power to pass to eccentric shaft 6 by V, two casing 5 interior eccentric shafts 6 rotate in the opposite direction, the inertia force that produces during eccentric shaft 6 High Rotation Speed is cancelled out each other in the horizontal direction, vertical direction superposes mutually, produce sine excitation power, thereby realize the vertical orientation vibration of block machine shaking platform 1 and moulding box, vibration is evenly distributed in whole shake table 1 scope, so that concrete rapid shaping within a short period of time, cement fully liquefies, and produces the building block of highly dense solidity.Behind the block forming, when vibrating device need to quit work, frequency control motor 2 outages stopped operating, thereby two eccentric shafts 6 stop operating, and shaking platform 1 recovers plateau.
