Description

(54) VIBRATION DRIVE

one

The invention relates to devices for immersing various structures in different environments, in particular building structures in the ground.

Known vibration immersion exciter vibration exciter mounted on the gripper, fastened to the loaded structure l1.

The drawbacks of the device are the necessity of lifting a long submerged structure with a fixed exciter in a vertical position and maintaining it in this position for some time (these operations are usually performed using construction jib cranes) the immersion direction, determined only by gravity, is possible the removal of the structure to the side, as well as the difficulty (and sometimes impossibility) of immersing the structure at an arbitrary angle.

The closest technical solution to the described one is a vibratory pile driver, including a frame with a driving rotor, a swing frame with a gripper for a submersible element mounted on it, a vibration exciter 2.

The disadvantage of this vibrator is the limited movement of the working body, which does not allow to immerse the elements at an angle.

The purpose of the invention is to provide the possibility of immersing the element at an angle. The goal is achieved by the fact that in the vibratory pile driver, turn on the frame with

0 a driving rotor, a swinging frame with a gripper mounted on it for immersing the element, a vibration exciter, a driving rotor equipped with guides arranged at an angle

5 to each other and sliders mounted on them, as well as a clip attached on the gripping side, for the submerged element, the frame being made in the form of a triangle, two of which are pivotally attached to the sliders, and a third is hinged to the gripper.

This embodiment of the device provides the possibility of a fixed

5 and forced immersion of the Construction at the required angle, increasing the productivity of the production of works and reducing their cost.

The drawing shows a vibrating truck with three positions of a submerged structure: I - vertical immersion II - middle of vertical immersion 111 - immersion at an angle below itself.

The pile driver contains a frame (chassis) 1 with wheels and outriggers, a movable triangular frame 2 and guides 3.1 whose axes intersect. The guides 3 are movable relative to the frame 1, for example, by fastening to a driven rotary rotor 4. The movable frame 2 of the angles is pivotally connected to the driven sliders 5 that come into contact with the guides 3. The third angle at the point located at the intersection of the axes two sliders 5, the frame 2 is hingedly connected to the gripper 6 of the submersible structure 7. On the gripper .6, a vibration exciter 8 is installed. The guides are provided with a opening collar 9 for guiding the submersible structure.

The device works as follows.

The driving rotary rotor 4 with the guides 3 and the movable frame 2 are positioned in the lower position, which is convenient for gripping the submerged structure 7, using the driving sliders 4. The structure 7 is clamped by the claw b, on which the vibration exciter 8 is fixed. Then, using the drive sliders 5, the movable frame 2 is set to its extreme upper position, lifting the submerged structure 7 upwards while turning the claw b pivotally connected to the movable frame 2. Thereafter, the plunger 7 enters the opening casing 9. Next, the driving rotary rotor 4 with the guides 3 is positioned to ensure that the structure is immersed at the required angle. After that, the vibration exciter 8 and the drive sliders 5 are activated. Under their combined action, the structure 7 is immersed (vibrated) in the working medium at the required angle.

At the same time, greater immersion accuracy is ensured and the process is very economical.
