Description

The invention relates to road and construction engineering, in particular to mechanisms for the shock development of high strength soils, including frozen.

The purpose of the invention is to improve the performance of the device.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. 1 (during the lifting of the working body); in fig. 3 - hook hook at the moment of contact with the stop.

The device includes a base machine 1, a vertical guide frame 2, an emphasis 3, a wedge working body 4, additional weight 5 with springs 6, a crankshaft 7 with a finger 8, fixed 9 and movable 10 parts of hook hook, three-bladed lever 11 with spring 12. The additional load 5 is pivotally mounted on the working body 4 by means of axis 13, the movable 10 and fixed 9 parts of the grip are pivotally interconnected by means of the axis 14, and the three-arm lever AND is hingedly mounted on the fixed part 9 of the grip using the axis 15. The working body 4 furnished floor 16 moving along the guides of the frame 2. The shaft 7 is driven in rotation by the drive 17. The movable part 10 of the hook grip is provided with a spring 18 rigidly connected to the fixed part 9 of the grip, and a stop 19 is fixed on the fixed part of the grip. in which the pin 8 is installed, and the fixed part 9 of the grip is fastened on the thread to the additional weight 5. To facilitate the lifting of the working body 4, the crankshaft 7 is provided with a counterweight 21. The working body 4 is designed as a loosening wedge, and the mobile part 10 of the grip form of double-arm lever.

The device works as follows.

The frame 2 is mounted on the ground and the crankshaft 7 is driven by a drive 17. Rotating, the shaft 7 finger 8 is in contact with the hook and moves the working body 4 up, while the additional weight 5 rotates on the axis 13 until the shaft 7 reaches the top point and the lever 11 reaches the stop 3. With further rotation of the shaft 7 lever 11,

in contact with the stop 3, rotates on the finger 15 relative to the fixed part 9 of the hook grip, the exit from contact with the mobile part 10 of the grip, while the mobile part 10 of the grip rotates by further rotation of the shaft 7

the finger 14, disengagement from the finger 8, and the loosening wedge 4 with a load of 5, freely falling, is inserted into the developed soil, while the moving part 10 of the gripper returns to its initial position under the action of the spring 18, and the spring 12 rotates the lever 11 to the limiter 19, and the lever engages with the movable part 10 of the grip. The crankshaft 7, continuing to rotate, reaches the lowest turning point and the pin 8 engages with the hook hook, after which the process is repeated.

The linear movement of the loosening wedge 4 occurs due to the guide 16 in contact with the guide frame 2. The rotation of the additional weight 5 occurs due to the fact that the shaft 7 rotates along the radius, and the wedge 4 moves linearly. Spring 6 reliably presses the additional load 5 to the wedge 4

when hitting the ground. The grooves 20 and the threaded fastening of the fixed part 9 of the hook grip are necessary for adjusting the height of the release of the loosening wedge 4 and the depth of its penetration into the ground.
