Definitions

  • the invention relates generically to a device for introducing an essentially vertical bottom slot in the course of the manufacture of a sealing or support wall, - with machine frame, bearing plate, at least two cutting wheels and motor / gear arrangement, the bearing plate being connected to the machine frame and carries the cutting wheels and the motor / gear arrangement, furthermore the cutting wheels are arranged on a common shaft and parts of the gear arrangement are encompassed by a cutting wheel.
  • the end shield can be connected to the machine frame in a steerable manner (DE-OS 36 02 387).
  • the drive motors are located above the end shield in the machine frame. Transmission elements lead from these drive motors through recesses and cavities in the end shield up to the area of the axis of the cutting wheels. Other gears are also accommodated in recesses or cavities in the end shield. The recesses or cavities become larger with increasing drive torque for the cutting wheels. They reduce the moment of inertia of the end shield. So that the considerable stresses can nonetheless be absorbed, the end shield must be made correspondingly thick. This is disadvantageous because it results in a relatively wide distance between the cutting wheels on the end plate side and consequently a disturbingly wide bottom rib remains between the cutting wheels when they are working.
  • the invention has for its object to further develop a generic device so that can work with a very narrow bearing plate with a small bearing plate side distance of the cutting wheels and nonetheless large drive torques can be entered into the cutting wheels.
  • the invention teaches that a double-sided projecting tubular housing is connected to the bearing plate, in which the two cutting wheels with surrounding hubs, which are placed on the common shaft, are mounted, that on one of the hubs a drive ring gear for the Cutting wheels is placed, which is fitted into the housing with clearance, and that the drive ring gear meshes with the drive pinions of a plurality of drive motors distributed over the circumference of the drive ring gear, which are mounted on a drive motor carrier inserted into the housing.
  • a preferred embodiment of the invention which is characterized by simplicity and functional reliability, is characterized in that the cutting wheels are mounted with their hubs in the housing by means of tapered roller bearings.
  • the drive ring gear is expediently placed on the assigned hub by means of a clamping set.
  • the number of drive motors distributed over the circumference of the drive ring gear is arbitrary. In order to achieve very uniform stress conditions, at least three drive motors will generally be provided.
  • a preferred embodiment of the invention, which allows very large drive torques to be introduced into the cutting wheels is characterized in that five drive motors which are designed as hydraulic motors are arranged over the circumference of the drive ring gear.
  • the cutting wheels will generally be placed on the common shaft with the interposition of a toothing, the cutting wheels can then also be easily removed during maintenance and care work.
  • the device according to the invention can be used with a very narrow bearing plate and consequently with a small distance between the cutting wheels on the bearing plate side. Therefore, only a narrow bottom rib remains between the cutting wheels, which breaks away or can be easily washed away.
  • the housing essential for the invention also ensures a safe encapsulation of the motor / gear arrangement. It goes without saying that suitable seals are arranged between the rotating and the non-rotating parts. Gaps between rotating and non-rotating parts can be easily flushed and thus kept free.
  • the device shown in detail in the figures serves to introduce an essentially vertical bottom slot in the course of the production of a sealing or support wall.
  • the non-rotating parts were drawn in thicker lines for clarity than the rotating parts shown with more hatching. Belong to the basic structure. a machine frame, a bearing plate 1, at least two cutting wheels 2 and a motor / gear arrangement 3.
  • the machine frame was not drawn.
  • the bearing plate 1 is connected to the machine frame, optionally steerable. It carries the cutting wheels 2 and the motor / gear arrangement 3.
  • the cutting wheels 2 are arranged on a common shaft 4. Parts of the gear arrangement are encompassed by a cutting wheel 2.
  • a tubular housing 5 projecting on both sides is connected to the end shield 1, which to the cutting wheels 2 is largely connected to the tubular part of the housing 5 verbun which cover 6 is completed.
  • the two cutting wheels 2 are mounted with surrounding hubs 7 placed on the common shaft 4.
  • a drive ring gear 8 for the cutting wheels 2 is placed on the right of the hubs 7, a drive ring gear 8 for the cutting wheels 2 is placed. This is fitted into the housing 5 with circumferential running play S.
  • the drive ring gear 8 meshes with the drive pinion 9 of a plurality of drive motors 3, which are distributed over the circumference of the drive ring gear 8.
  • These drive motors 3 are mounted on a drive motor carrier 10 inserted into the housing.
  • the cutting wheels 2 are supported with their hubs 7 in the housing by means of tapered roller bearings 11.
  • the drive ring gear 8 is placed on the associated hub 7 by means of the clamping set 12.
  • five drive motors 3 are arranged over the circumference of the drive ring gear 8. These are designed as hydraulic motors.
  • the cutting wheels 2 are placed on the common shaft 4 with the interposition of a toothing 13.
  • the cutting wheels 2 are provided on the circumference with cutting teeth 14.
