Definitions

  • the invention relates to a wall saw with a frame that can be moved or moved in the direction of advance on wheels, in which a saw motor carriage carrying the chain saw is arranged.
  • Wall saws of this type are known and are used to make horizontal cuts in masonry, e.g. for drains.
  • Wall saws of this type must be built to be extremely robust in order to meet the high mechanical requirements in use on the construction site. Setbacks should be avoided when the saw blade is inserted into the masonry. Furthermore, it is necessary to provide a height adjustment for the saw in order to be able to adapt the height of the saw cut to the requirements.
  • the height of the saw should be somewhat elastic, since cuts should preferably be made in masonry joints and this requires a corresponding elasticity in the height.
  • the invention is characterized in that an outer frame is provided which has at least three preferably motor-driven feed wheels and that the outer frame receives an inner frame which is movable relative to the outer frame both in height and transversely to the feed direction and which has the saw motor carriage.
  • Fig.1 is purely schematic the supervision of a masonry saw in the company.
  • 2 and 3 are schematic line drawings and show the structure of the outer frame and the inner frame.
  • Fig.4 is the top view of the lower frame or upper frame of the outer frame.
  • 5 is a top view of the lower frame part and the inner frame,
  • FIG. 6 shows a side view of the frame of the chain saw and
  • FIG. 7 shows a detailed view.
  • the masonry saw according to the invention consists of an outer frame 1 and an inner frame 2.
  • the outer frame 1 gives the entire structure the necessary structural strength and has four wheels 3, 4 with which the masonry saw in the feed direction 5 or can be moved in the opposite direction.
  • the feed takes place through the feed motor 6, which drives the shafts 9, 10 via the two chain drives 7, 8, on which both wheels 3, 4 are seated.
  • the wheels 3 are designed as double wheels.
  • the inner frame essentially comprises two guide rods 11, 12, on which a saw motor carriage 13 is displaceable in the directions of the arrow 14.
  • the saw motor carriage 13 can be moved forcefully along the guide rods 11, 12 via a pinion and a toothed rack 16.
  • the cranks 17, 18 serve to adjust the height of the guide rods 11, 12 and thus of the saw motor carriage 13 in order to be able to select the cutting height accordingly.
  • the handles 47 are used to guide the wall saw.
  • the saw blade 20 is pierced into the partially sawn through wall 21 and the sawing direction corresponds to the feed direction 5.
  • the outer frame consists of an upper frame part 22 and a lower frame part 23. These two frame parts are firmly connected to one another via four guide columns 24. The wheels 3, 4 sit on the lower frame part 23 on the shafts 9, 10.
  • the inner frame comprises the guide rods 11, 12, at the ends of which sliding pieces 25 are arranged, which can slide on the guide columns 24.
  • the saw motor carriage 13 is slidably mounted on the guide rods 11, 12 by means of guide sleeves 26.
  • the chainsaw 19 with the saw blade 20 is seated on the saw motor carriage 13.
  • the saw motor carriage 13 can be moved along the guide rods 11, 12 via the handwheel 15 in order to either insert the saw blade 20 into the wall to be sawed or pull it out of the wall.
  • FIG. 4 shows the top view of an upper frame part or lower frame part. Both elements have the same structure.
  • One part essentially comprises two longitudinal struts 27 and two cross struts 28.
  • the guide columns 24, which produce the connection to the frame part above or below, are also fastened to the crossing points.
  • Fig. 5 shows the top view of the lower frame part and the inner frame with the engines removed.
  • the saw motor carriage 13 consists of the motor support plate 29 and the guide sleeves 26 which grip around the guide rods 11, 12 and can be moved on it.
  • the shaft 30, which extends downward from the handwheel 15 (FIG. 3), is mounted in the motor mounting plate 29 and ends on the underside of the motor mounting plate 29 in a pinion which meshes with a toothed rack 16 on the side.
  • the rack 16 is connected to the sliders 25. By rotating the shaft 30, the saw motor carriage 13 is moved forwards or backwards. The necessary forces can be applied by the large handwheel 15.
  • the guide rods 11, 12 hang on joints 31 on the sliders 25, so that it is possible to arrange the guide rods parallel to one another but obliquely to the lower frame part.
  • the bearing blocks 32 serve to support the shafts 9, 10 for the wheels 3, 4.
  • the wheels 3 are designed as double wheels.
  • the shafts 9, 10 are driven by a motor 33 on a motor support plate 34 connected to the lower frame part by means of two chains 35, 36.
  • a coupling piece 37 causes the end coupling of the shaft 10 or 9 in the pulled-out state and the rotationally fixed connection of the respective shaft to the associated wheel in the pushed-in state. This makes it possible to corner and maneuver when cutting.
  • crank 17 continues in a shaft 38 which is mounted on the underside of the upper frame part 22.
  • a pinion 39 is provided in the immediate vicinity of the guide columns 24 each of which a chain 40 is driven, which is guided around a further pinion 41 on the lower frame part 23.
  • a slider 25 is flanged to one of the two chain sides. When turning the crank 17, the sliders 25 and with them the guide rods attached to them (hidden in FIG. 6) and the toothed rack 16 are displaced along the guide columns 24. There is an identical arrangement for the other two guide columns. the crank 18 (Fig.1).
  • one of the sliding rollers is designated, on which the masonry saw is supported on the wall 21 during cutting.
  • the second such sliding roller 43 can be seen in Fig.1.
  • the one sliding roller 42 is attached in the corner region of the outer frame, so that it protrudes both over the narrow side and over the broad side.
  • This sliding roller 42 can thus interact both with the sliding roller 43 on the narrow side and with the third sliding roller 44 at the other end of the broad side.
  • the drive wheels 3 are located within the outer circumference of the outer frame, so that in practice they do not hinder the rolling on the slide rollers 42, 44.
  • FIG. 7 shows a preferred embodiment of the shaft 38.
  • a ratchet wheel 45 is arranged in the vicinity of the crank 17, the ratchet 46 permitting the rotation in order to lift the inner frame upwards. The downward movement, however, is blocked by the pawl 46. To release this lock, the pawl 46 must be released so that the shaft 38 can rotate in the corresponding direction.
  • the feed via the wheels 3, 4 is preferably provided such that the machine can be moved in both directions.
  • a hard metal chain saw is preferably provided for the saw blade.
  • the motors for the chain drive and for the feed are preferably 380V motors, but can also be internal combustion engines.
  • a large-sized coolant pump with a large coolant tank is preferably provided for cooling and lubricating the saw chain.
  • the outer frame offers enough space for this.
  • a cutting depth of 600 mm can be achieved with a maximum cutting height from the floor of 490 mm and a minimum cutting height from the floor of 50 mm.
  • the adjustable inclination of the saw blade can be up to 15 °. All of this data is for example only and depends on the respective dimensions.
  • saw blade used in the description here means the combination of a guide rail with the rotating saw chain and the deflection roller, as is known for chainsaws.
