Abstract

The utility model relates to a composite vibration-damping mechanism of a vibratory plate compactor, wherein, two steel helical compression springs which are respectively arranged between a tamping plate and a motor seat vertically via an upper and a lower spring seats pass through the longitudinal median planes of the upper and the lower spring seats; four rubber springs are horizontally arranged between a supporting plate on the tamping plate and the motor seat. The utility model used for building and engineering construction fully utilizes the respective advantages of the rubber springs and the steel helical compression springs, has favorable vibration-damping effect and enough rigidity; the utility model is used for a vibration-damping system of the vibratory plate compactor, obtain the optimum combination of the vibration-damping effect and system rigidity.

Description

Vibratory plate compactor combined vibration-damping mechanism
The utility model relates to a kind of building machinery, relates to a kind of building and the engineering construction damper mechanism with vibratory plate compactor or rather.
At present, the damper mechanism of vibratory plate compactor all adopts simple rubber spring as damping element, and its shortcoming is that rigidity is low, thereby causes upper spider bigger with respect to the tamping plate displacement, influences the running stability of rammer machine transmission system.
The purpose of this utility model is: design a kind of existing favorable damping effect, the damper mechanism of enough rigidity is arranged again, to overcome the shortcoming of existing damper mechanism insufficient rigidity.
The utility model is achieved in that it comprises tamping plate, motor and seat thereof, rubber spring, steel spring and seat etc. thereof, wherein: two steel spiral compression springs vertically are installed between tamping plate and the motor by last lower spring cup respectively, and by its longitudinal median plane, four rubber springs are circular, two ends are the connection bolt of M10 * 25, level is installed between the support plate and motor cabinet on the tamping plate respectively, and be symmetrical in the tamping plate longitudinal median plane, two ends with nut and packing ring respectively with tamping plate on support plate link to each other with motor cabinet.
The utility model has the advantages that: because of having used two steel spiral compression springs, vertically be installed between tamping plate and the motor cabinet, be used to bear the weight of motor and upper spider by spring seat.So increased the rigidity of system, four cylindrical rubber springs, level is installed between the support plate and motor cabinet on the tamping plate, is used for the vibration damping of system.
Adopt above-mentioned combined vibration-damping mechanism, overcome the shortcoming of existing damper mechanism insufficient rigidity, realized a kind of existing good damping property, the vibratory plate compactor damper mechanism of enough rigidity is arranged again.
Below in conjunction with accompanying drawing the utility model embodiment is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a mounting structure plan view of the present utility model.
Shown in Fig. 1-2, spiral compression spring 7 vertically is installed on the longitudinal median plane between tamping plate 1 and the motor cabinet 3 by upper and lower spring seat 6, rubber spring 2 levels are installed between the support plate and motor cabinet 3 on the tamping plate 1, two ends are fastening by nut 4 and packing ring 8, but the motor 5 of mounting strap belt pulley is installed on the motor cabinet 3, during work, motor reaches the weight that goes up the machine frame and is mainly born by spiral compression spring, thereby reaches the purpose that increases system stiffness.Rubber spring then mainly plays damping effect.
Present embodiment is applied to the dull and stereotyped damper mechanism that rams of small vibrating, has realized the good damping property and the best of breed of system stiffness.Survey only 0.05mm of upper spider amplitude during machine works, be equivalent to 1/8 of existing industry standard (JG/T5013.2) 0.4mm.
