Description

Technical Field

[0001] The present invention relates to the technical field of building cutting, and particularly to a building grooving tool. Background Art

[0002] During the construction of building installation of water and electricity, it is necessary to groove the surface of the building body and install water and electricity pipelines.

[0003] Existing grooving devices include hand-held grooving tools and mobile vertical devices. Since the hand-held grooving tool needs to be held by the operator, it consumes a huge amount of physical strength during use, and at the same time, the generated dust is more likely to be inhaled by the operator, which is very dangerous. The mobile vertical device includes a mobile platform, and a rotating platform is installed on the mobile platform. A cutting mechanism is installed on the rotating platform or a hand-held grooving tool is directly installed on the rotating platform, but this device can only groove the wall. Summary of the Invention

[0005] The support structure includes two support columns. Sliding sleeves are slidably sleeved on the support columns. A first fixing plate is fixedly connected between the two sliding sleeves. The rotating frame is rotatably assembled on the first fixing plate. That is, the support structure and the rotating frame can be disassembled from each other, and the rotating frame can be used alone.

[0006] The sliding frame is slidably engaged with the rotating frame. The sliding frame includes a frame. A second motor is fixedly connected inside the frame. Motor shafts extend out from both ends of the second motor, and swing arms are sleeved on the motor shafts. A connecting rod is fixedly connected in the middle of the two swing arms. The other end of the swing arm is fixedly and rotatably connected to a rotating shaft. A plurality of saw blades are fixedly connected in the middle of the rotating shaft. A first pulley is fixedly connected to one end of the rotating shaft. A second pulley is fixedly connected to one of the motor shafts. A belt is commonly sleeved on the first pulley and the second pulley. The number and spacing of the saw blades are controlled, that is, the width of the groove is set. The second motor is started, and the rotating shaft can be driven to rotate through the second pulley, the belt and the second pulley, so that the saw blades cut the building body. During the process of the sliding frame sliding on the rotating frame, a groove can be cut.

[0007] An electric cylinder is rotatably connected inside the frame. The output end of the electric cylinder is rotatably connected to the connecting rod. When the electric cylinder operates, the swing arm rotates, thereby controlling the cutting depth.

[0008] Preferably, support feet are provided below the support columns.

When the rotating frame 2 and the support structure 1 are assembled with the matching rod 23 inserted on the support tube 14, and then the anti-dropping nut is installed, the combination is used for grooving the wall.

[0034] Side plates 29 are fixedly connected to the ends of the sliding rods 21 to fix the four sliding rods 31 and form a whole. A support protrusion 210 is fixedly connected to one side of the side plate 29 to prevent the side plate 29 from directly contacting the building body. When the rotating frame 2 is used alone, its support protrusion 210 contacts the ground, and the internal sliding frame 3 can be controlled to realize grooving the ground. A handle 26 is fixedly connected to the side plate 29. When the rotating frame 2 is installed on the support structure 1, pulling the handle 26 can rotate the rotating frame 2, thereby controlling the grooving direction.

[0035] Sprockets 27 are provided on both side plates 29, and a chain 28 is wound around the sprockets 27. The chain 28 is arranged in a disconnected manner and is fixedly connected to both sides of the frame 31 at both ends.
