Abstract

The invention relates to building machines and can be used in lifting and impacting rippers for loosening durable soils. The goal is to increase the durability of the working equipment by turning off the vibrator during lifting and dropping the working device (RO). The working equipment includes a hoisting rope 1 and PO 2 in the form of a hollow body (K) 3, a wedge-shaped tip and a vibrator made of gear flywheels (M) installed inside K 3. Each of the latter consists of two parts 5 and 6, which are mounted on shafts 7.8. Both parts are installed with the possibility of their engagement by means of coupling halves 9.10 fixed on adjacent side precast parts of 5.6 M. Unbalances 11, 12 are mounted on parts of 6 M. The vibrator control mechanism is made of pressure strips 13 connecting the pairs 6 M parts in a vertical plane, with springs 14, rods 15 and levers 16. Levers 16 are placed outside the K 3 with the possibility of interaction with adjustable stops 17. During lifting and dropping the PO 2, the vibrator is switched off and thereby the vibration of the working equipment is eliminated. This increases the efficiency of the working equipment and its service life. 1 il.

Description

The invention relates to building machines and can be used in lifting and impacting rippers for loosening durable soils.

The aim of the invention is to increase the durability of the working equipment by turning off the vibrator during lifting and dropping the working member.

The drawing shows the proposed working equipment ripper lifting and impact action.

The working equipment includes a hoisting rope 1 and a working body 2, comprising a hollow body 3, a wedge-shaped tip 4 and a vibrator mounted inside the body, made of gear flywheels, each of which consists of two parts 5 and 6, which are mounted on shafts 7 and 8, at the same time, parts 6 of flywheels are loosely mounted on shafts 7 and 8, and parts 5 of flywheels are rigid. Parts 6 of the flywheel and parts of the 5 flywheels in the vertical plrskosti form between each other, gear pairs and are equipped with coupling halves 9 and 10. On parts 6 of the flywheels, unbalances 11 and 12 are mounted in pairs in the opposite phase. The vibrator control mechanism is made of pressure bars 13, interconnecting pairs of parts 6 of flywheels in a vertical plane and equipped with springs 14, rods 15, pivotally mounted with bars 13 and passing through openings in the walls of the housing 3 outward, switching levers 16 placed outside the housing 3 with the ability to interact with adjustable lugs 17 mounted on the frame 18 of the ripper. The stops 17 are fixed on the frame in height so that the inclusion levers 16 begin contact with them until the working body 2 stops against the ground in order to ensure timely activation

 the vibrator into operation by connecting parts 6 with parts of 5 flywheels through half couplings 9 and 10. The length of the stops 17 is set taking into account the maximum depth of loosening. On van 7 is installed by means of an overrunning clutch pulley 19, through which the hoisting rope 1 "is passed

Working equipment ripper works as follows.

When lifting the working member 2. working body 2 of the part 5 of the flywheel on the shafts 7 and 8, accelerating, accumulate kinematic energy. At this time, the parts of the 6 flywheels that are free to sit on the shafts 7 and 8 and are separated from the parts of the 5 flywheels do not rotate, and the unbalances 11 and 12 do not create a vibration effect. At the moment of dropping the working body 2, the pulley 19 is. rotates in the opposite direction and opens the overrunning clutch, which separates the shaft 7 with the pulley 19, and the shafts 7 and 8 with parts of the 5 flywheels continue to rotate in a given direction. At a given moment before the tip 4 hits the ground, the inclusion levers 16, contact with the stops 17, through the rods 15 act on the pressure bars 13 and connect the parts 6 of the flywheels and the parts 5 of the flywheels to each other through the coupling halves 9 and 10. Into this. the moment of part 6 of the flywheels with unbalancers 11 and 12 begin to rotate with parts of the five flywheels, creating a vibration effect that continues during the impact and penetration of the loosening tip 4 into the ground, while the inclusion levers 16, continuing

Contact with the stops 17, keep parts 6 and 5 of the flywheels in the connected state. At the beginning of the lifting of the working body 2 after the tip 4 has been inserted into the ground, the vibration continues until the switching levers 16 come out of contact with the stops 17, then due to the forces of the springs 14, the pressure bars 13 retract and release the coupling half 9 and 10, respectively parts 6 and 5 flywheels. Parts 6 of flywheels with unbalances 11 and 12 at this moment cease their rotation and vibration action.

With the further rise of the working body 2, the cycle is repeated.

Thus, supplying the vibrator with gears mounted on the flywheel shafts freely and fixing unbalances on them, as well as installing the vibrator control mechanism, allows turning off the vibrator and eliminating the working equipment of the ripper when the working device is lifted and dropped, which increases its efficiency. reliability and durability.
