Definitions

  • the invention relates to an activation system for cutting or milling systems, preferably for cross or longitudinal cutting heads or rotating milling drums, on hydraulic carrier devices, in particular on hydraulic excavators, Backhoe loaders, cultivators. Areas of application for these excavator attachments are Special civil engineering, tunnel and hydraulic engineering, demolition of concrete etc. Machining hard Rock formations.
  • an eccentric drive for radially oscillating roller, roller and milling drilling tools with a separate drive for the fast rotating eccentric shaft and a slowly running sleeve with tools is known, the dynamic balancing being carried out by adjustable counterweights.
  • the invention therefore has as its object an activation system for Cutting heads of hydraulic carrier devices to develop the cutting heads for targeted striking movements with different striking power and direction and - frequency activated and that as an independent system independent of the rotating movements of the cutting or milling heads and tools can be switched on and off as required.
  • the object is achieved in that the activation system for cutting heads of hydraulic carrier devices, that it is designed as a separately driven additional activation device and on the gear housing of the cutting head between the cutting head and the carrier device is fixed or adjustable.
  • the activation device consists of a shock pulse generator built into its housing and an independent drive motor.
  • the activation device according to the invention is preferably arranged fixedly and centrally on the head of the gear housing of the cutting or milling head between the latter and a damping system for the excavator attachment console of the carrier device.
  • the activation device is, however, also arranged laterally fixed or adjustable in the direction of impact on the transmission housing. They can also be set differently from one another.
  • the activation system is equipped with a combination of two activation devices, one activation device in the middle and one activation device on the side of the gear housing, for different directions of impact that differ from the cutting direction of the cutting head.
  • the activation devices arranged on the side of the gear housing can be adjusted by an angle ⁇ in the range 0 ° ⁇ ⁇ 90 ° with respect to the gear housing, so that each activation device with its impact direction and impact force preferably acts in the cutting direction of the cutting tools of the cutting or milling head.
  • the activation device of the activation system is also characterized in that its impact pulse generator built into the housing is preferably constructed as a rotating impact system with a rotating unbalanced shaft. Due to their variable, controllable speed, preferably a speed> 2000 rpm, impact forces and frequencies can be continuously adjusted during the cutting process of the cutting head.
  • the impact pulse generator can be constructed as a vertical impact system with a vertically moving impact piston. Due to its variable, controllable stroke length, impact forces and frequencies can also be continuously adjusted during the cutting process.
  • the advantage of the activation system according to the invention is that the activation device can be retrofitted appropriately as an independent separate additional device to extraction machines or excavator attachment cutters and can be switched on or off independently of the cutting process if necessary.
  • cutting heads can also have a specially installed activation device.
  • the use of several activation devices on one cutting head in different positions makes it possible to change and control the direction, impact forces and frequencies of the cutting head for different purposes.
  • An application for different carrier devices is possible. Harmful vibrations or resonances caused by the impact pulse generator are largely eliminated and absorbed by the independent drive motor of the drive device, the controllability of the impact forces and the built-in damping system compared to the carrier device. The vibration load on the carrier device is minimized.
  • the activation system shown in FIG. 1 for cutting heads of hydraulic carrier devices, preferably excavator attachments, is arranged as an activation device 3 on the gear housing 2 of the cutting head 1 with the cutting tools 6, which are preferably designed as hard metal chisels.
  • the transverse or longitudinal cutting head 1 is attached to the gear housing 2 according to FIG. 1, 2 by fastening elements 7.
  • the drive for the cutting movements of the cross cutting head 1 is carried out by an independent drive motor 11 via a corresponding gear in the gear housing 2.
  • FIGS 1 and 2 show that the activation device 3 is arranged centrally on the gear housing 2, ie between the gear housing 2 and the carrier device of the excavator attachment tiller ,
  • a damping system 4 with damping elements is installed between the excavator attachment bracket 5 of the excavator attachment tiller and the activation device 3.
  • the activation device 3 is constructed in such a way that an independent drive motor 8 and an impact pulse generator 9 are located in its housing 10, so that the transverse or longitudinal cutting head 1 (FIG. 3 or FIG. 4) has an additional impact effect of a certain impact force and impact frequency in its cutting direction receives. Since the activation device 3 is designed as a separately driven additional device, it can also be retrofitted to existing, already working cutting heads 1.
  • the activation device 3 can be arranged at various points on the gear housing 2 of the cutting head 1, preferably in the center according to FIGS. 1, 2, but also laterally on the gear housing 2 according to FIGS , FIG.
  • FIG. 5 shows a longitudinal cutting head 1 with two activation devices 3 arranged laterally on the gear housing 2, which can be adjusted with different impact force for different directions of impact of a cutting head 1 and can be controlled with respect to impact force and frequencies during the cutting process.
  • the activating device 3 arranged in the middle is fixed and the activating device 3 arranged on the side is adjustable or installed, ie the activating devices 3 can act on the cutting head 1 simultaneously with two different directions of impact and impact forces.
  • Different impact forces and frequencies of the activation device 3 are controlled by its built-in pulse generator 9 in the housing 10.
  • a rotating unbalanced shaft with a variable speed of> 2000 rpm, preferably 2000 rpm to 4000 rpm, is preferably installed as the pulse generator 9.
  • the striking movements of the cutting head 1 are thus generated by eccentric rotating movements.
  • a vertically moving percussion piston with variable stroke length makes it possible to control different percussion forces and frequencies during the cutting or milling process of the cutting head 1.
  • other methods of generating impact energy can also be used.
  • the resulting vibrations are transmitted via the housing 2 of the cutting head as an excitation force to the cutting tools 6 and thus into the material to be cut.
  • This controllability of the impact effect by changing the piston stroke of the impact piston in the vertical system or changing the rotational speed of the unbalanced shaft in the rotating system also during the cutting process enable the installation of activation devices 3 of different strengths for different applications.
  • a plurality of mutually adjustable activation devices 3 can be used, that is to say can be switched on or off, so that the activation system according to the invention with a transverse or longitudinal cutting head 1 is suitable for various extraction and tunneling machines as carrier devices for tunnel, mining and sewer construction or demolition work.
