Description
[technical field]
The utility model relates to a kind of concrete production equipment, is specifically related to the closely knit driving mechanism of a kind of concrete low frequency, belongs to the corollary equipment technical field of concrete prefabricated element production line.
[background technology]
Concrete compaction has closely knit and closely knit two classes of low frequency of high frequency, and conventional densification generally adopts high frequency closely knit, and the closely knit aggregates such as the stone that concrete density is large that easily make of high frequency sink, and make concrete block aggregate uneven, cause the intensity of concrete structure to reduce.
The closely knit tradition of low frequency adopts the slider-crank mechanism of the mechanism that swings back and forth more, when driving link is large-scale workpiece, adopts slider-crank mechanism just to seem more painstaking.Traditional mode due to driving link be large-scale workpiece time, crank block structure certainly will be caused also and then to increase, the financial cost which increasing manufacture and the space cost put.And swinging back and forth neither be very desirable to the effect of concrete secret room.
Therefore, for solving the problems of the technologies described above, necessaryly provide a kind of novel closely knit driving mechanism of concrete low frequency, to overcome described defect of the prior art.
[utility model content]
For solving the problem, the purpose of this utility model be to provide a kind of reasonable in design, structure simple, working stability and the closely knit driving mechanism of concrete low frequency of dependable performance.
For achieving the above object, the technical scheme that the utility model is taked is: the closely knit driving mechanism of a kind of concrete low frequency, it connects and drives concrete vibrating stand, and it comprises support, bearing block, bearing, power transmission shaft, eccentric block, large belt wheel, belt, small pulley and reducing motor; Wherein, described bearing block is immobilizated on support; Described bearing is installed in bearing block; Described power transmission shaft is articulated on bearing, and its one end is provided with described eccentric block, and the other end is provided with described large belt wheel; Described eccentric block is connected to described concrete vibrating stand; Described belt connects described large belt wheel and small pulley; Described reducing motor is immobilizated in the side of support, and it connects and drives described small pulley.
The closely knit driving mechanism of concrete low frequency of the present utility model is set to further: the periphery of described eccentric block and inner hole surface decentraction.
The closely knit driving mechanism of concrete low frequency of the present utility model is set to further: described eccentric block, large belt wheel are connected on power transmission shaft respectively by flat key.
The closely knit driving mechanism of concrete low frequency of the present utility model is also set to: the two ends of described bearing are respectively equipped with a packing ring; Described packing ring is installed on bearing block.
Compared with prior art, the utility model has following beneficial effect: the closely knit driving mechanism of concrete low frequency of the present utility model is reasonable in design, structure is simple, working stability, and dependable performance, it utilizes reducing motor, the gearratio of large small belt pulley slows down, effect eccentric block being reached slowly run, thus drives concrete vibrating stand to do low-frequency vibration.
[accompanying drawing explanation]
Fig. 1 is the schematic diagram of the closely knit driving mechanism of concrete low frequency of the present utility model.
[detailed description of the invention]
Refer to shown in Figure of description 1, the utility model is the closely knit driving mechanism of a kind of concrete low frequency, it connects and drives concrete vibrating stand 10, and it is assembled by a few part such as support 1, bearing block 2, bearing 3, power transmission shaft 4, eccentric block 5, large belt wheel 6, belt 7, small pulley 8 and reducing motor 9.
Wherein, described concrete vibrating stand 10 is the concrete vibrating stand 10 of prior art, does not repeat them here.
Described bearing block 2 is immobilizated on support 1.Described bearing 3 is installed in bearing block 2.Described bearing block 2 can strengthen the stability of power transmission shaft 4, and the force of rolling friction that bearing 3 rotates rotates power transmission shaft 4 and do not have any impact.Further, the two ends of described bearing 3 are respectively equipped with a packing ring 11.Described packing ring 11 is installed on bearing block 2, and it can be protected bearing 3.
Described power transmission shaft 4 is articulated on bearing 3, and its one end is provided with described eccentric block 5, and the other end is provided with described large belt wheel 6.Specifically, described eccentric block 5, large belt wheel 6 are connected on power transmission shaft 4 respectively by flat key 12, thus can bear larger moment of torsion and non-slip.
Described eccentric block 5 is connected to described concrete vibrating stand 10, its periphery and inner hole surface decentraction, and its eccentric distance is d.When eccentric block 5 inner hole surface around power transmission shaft 4 heart line rotate time, the track of the periphery of eccentric block 5 does well-regulated motion in the horizontal plane.
Described belt 7 connects described large belt wheel 6 and small pulley 8, thus makes the large belt wheel 6 of small pulley 8 transmission.
Described reducing motor 9 is immobilizated in the side of support 1, and it connects and drives described small pulley 8, and output speed is lowered by the decelerator carried by reducing motor 9.Described large belt wheel 6 and small pulley 8 by certain gearratio, thus make the rotating speed of power transmission shaft 4 reduce further again.
The course of work of the closely knit driving mechanism of concrete low frequency of the present utility model is as follows: drive small pulley 8, belt 7, large belt wheel 6, power transmission shaft 4 and eccentric block 5 successively by reducing motor 9, make eccentric block 5 drive described concrete vibrating stand 10.
The closely knit driving mechanism of concrete low frequency of the present utility model reduces the rotating speed of its output shaft by reducing motor 9, large belt wheel 6 is driven to carry out transmitting torque by small pulley 8 again, rotating speed is reduced further according to certain gearratio, make the eccentric block 5 be connected on power transmission shaft 4 do low speed to horizontally rotate, thus drive concrete compaction horizontal vibration platform to do low-frequency vibration.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
