Abstract
The utility model discloses a vibratory hammer with a changeable eccentric torque, wherein a vibration exciter box is internally equipped with a rotation shaft which is meshed through a gear; the two ends of the rotation shaft are rotatably arranged in bearing holes of the vibration exciter box; the middle part of the rotation shaft is equipped with an eccentric body; the vibratory hammer with a changeable eccentric torque is characterized in that the eccentric body comprises a static eccentric block and a dynamic eccentric block; the dynamic eccentric block is hollowly sleeved on the rotation shaft to swing circumferentially; and the static eccentric block is fixedly connected to the rotation shaft. The vibratory hammer provided by the utility model has two types of variable fixed eccentric torque, and therefore the working requirements of the vibratory hammer are met well.
Description
Technical field
The utility model relates to a kind of constructional engineering machinery, what be specifically related to is a kind of improvement invention of vibrating hammer.
Background technology
Vibrating hammer is widely used on the building site, mainly is the piling that is used for building, and its operating principle is that the rotation by eccentric block produces vibration.The eccentric block of traditional vibrating hammer generally fixedly installs, so its eccentric moment is unique changeless, can not satisfy the need of work of vibrating hammer well.
Summary of the invention
In view of the problem that present known technology exists, the technical problems to be solved in the utility model is to be to provide a kind of to have two kinds and decide eccentric moment, can better satisfy the change eccentric moment vibrating hammer of need of work.
For solving the problems of the technologies described above, the utility model takes following technical scheme to finish:
Become the vibrating hammer of eccentric moment, gears engaged is passed through in the rotating shaft that is provided with in its vibrator casing, the two axial ends of rotating shaft is rotatable to be located in the dead eye of vibrator casing, the middle part of rotating shaft is provided with eccentric body, it is characterized in that: described eccentric body comprises quiet eccentric block and moving eccentric block, moving eccentric block sky is enclosed within the described rotating shaft and can circumferentially swings, and quiet eccentric block is fixedlyed connected with described rotating shaft.The tangential end face that described quiet eccentric block is relative with moving eccentric block is equipped with damper rubber.Described damper rubber is installed in the draw-in groove that the tangential end face of quiet eccentric block and moving eccentric block is provided with and can freely dismantles.
Moving eccentric block can circumferentially be swung in rotating shaft, when rotating shaft is towards a direction rotation like this, one side of moving eccentric block can be taken advantage of a situation and be leaned against a side of quiet eccentric block, both understand inertia and are close to together to rotate and produce a kind of eccentric moment of deciding, and rotating shaft is when rotating in the opposite direction, the opposite side of moving eccentric block can be taken advantage of a situation and be leaned against the opposite side of quiet eccentric block, both also can inertia be close to rotate together and produce the another kind of different eccentric moment of deciding, so the utility model can realize that variable two kinds are decided eccentric moment, have satisfied the need of work of vibrating hammer better.Impact when being provided with of damper rubber can be cushioned moving eccentric block and contact with quiet eccentric block, and damper rubber can be convenient for changing.
Description of drawings
The utility model has following accompanying drawing:
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Accompanying drawing has been represented the technical solution of the utility model and embodiment, further describes each relevant details and operating principle thereof of embodiment below more in conjunction with the accompanying drawings.
With reference to accompanying drawing 1, this kind becomes the vibrating hammer of eccentric moment, the rotating shaft 2 that is provided with in its vibrator casing is by gear 1 engagement, the two axial ends of rotating shaft 2 is rotatable to be located in the dead eye of vibrator casing, the middle part of rotating shaft 2 is provided with eccentric body (above be the universal architecture of prior art), described eccentric body comprises eccentric mounting 5, cover cap 6, case 7, quiet eccentric block 9 and moving eccentric block 8, eccentric mounting 5 is fixedly connected in the described rotating shaft 2, quiet eccentric block 9 and moving eccentric block 8 are located in the case 7, moving eccentric block 8 skies are enclosed within the described rotating shaft 2 and can circumferentially swing, moving eccentric block 8 circumferentially have a sector notch, described quiet eccentric block 9 is located in the sector notch, eccentric mounting 5, cover cap 6, fixedly connected with 4 by bearing pin 3 between quiet eccentric block 9 and the case 7, so form a fixed connection between quiet eccentric block 9 and the described rotating shaft 2, described quiet eccentric block 9 is equipped with draw-in groove 10 with moving eccentric block 8 relative tangential end faces, be provided with damper rubber 11 in the draw-in groove 10, damper rubber 11 is installed in the draw-in groove 10 can freedom carry out dismounting and change easily.
The course of work of the present utility model, when rotating shaft when direction is rotated, one side of moving eccentric block can be taken advantage of a situation and be leaned against a side of quiet eccentric block, both understand inertia and are close to together to rotate and produce a kind of eccentric moment of deciding, and rotating shaft is when rotating in the opposite direction, the opposite side of moving eccentric block can be taken advantage of a situation and be leaned against the opposite side of quiet eccentric block, and both also can inertia be close to rotate together and produce the another kind of different eccentric moment of deciding, and decide the need of work that eccentric moment can satisfy vibrating hammer better for two kinds.
