Description

Technical Field

[0001] The utility model relates to a wall saw device, in particular to a high-frequency wall saw machine. Background Art

[0002] Wall saws are advanced engineering tools used in building renovation and reinforcement construction. As specialized cutting tools, they are suitable for cutting hard materials such as reinforced concrete, rock, ceramics, and brick walls. They are widely used for opening doors, windows, and vents in walls, cutting reinforced concrete beams and columns, cutting floor slabs and bridges, and processing stone. A typical wall saw consists of a track, a saw head, and a saw blade. The saw head slides smoothly along the track via rollers that engage the track. The rollers must grip the sides of the track and slide along it. Currently, the most commonly used roller grip adjustment mechanism uses a cam, but most cam-adjustable rollers are difficult to operate and lock. Furthermore, once the rollers are locked to the track by the cam mechanism, deviations in track width or wear of the track and rollers over time can cause the rollers to loosen, affecting cutting performance.

One end of the handle 9 is fixedly connected to the housing of the first motor 241, and the other end is fixedly connected to the frame 21 via a cable box 10. The cable box 10 has a storage space for cables. A channel for the cables to pass through the handle 9 is formed through the channel, which is connected to the storage space. The provision of the handle 9 not only facilitates the handling of the entire wall saw, but also allows the cables to pass through and be stored in the cable box 10, thus avoiding cable clutter that may affect the use of the wall saw.

[0064] During use of this embodiment, the foot 11 is first fixed to the cutting surface by expansion bolts, and then the first roller 4 and the second roller 5 are tightly clamped to both sides of the track 1 by rotating the handle seat 61, wherein the specific adjustment steps of the second roller 5 are as follows: press down the handle 612 away from one end of the seat body 611 to lift the other end upward, and since the upper end of the connecting rod 641 is inserted into the strip hole 642, the lifted end of the handle 612 drives the connecting rod 641 to move upward, so that the head 643 is freed from the restriction of the positioning hole 65, and then the handle and the seat body 611 are rotated. Since the spline petal 633 is located at the offset One side of the central shaft 62, and meshing with the petal gear 631 fixed on the upper end of the eccentric shaft 62, so that when the seat body 611 rotates, the spline petals 633 and the petal gear 631 are driven to rotate accordingly, and the petal gear 631 drives the eccentric shaft 62 to rotate, thereby driving the second roller 5 at the bottom of the eccentric shaft 62 to rotate to a state of being in contact with the side wall of the track 1; at this time, the pressed handle 612 is released to reset the handle 612, and the reset spring 644 drives the connecting rod 641 and the head 643 to move downward, so that the head 643 is inserted into the corresponding positioning hole 65, completing the adjustment and locking of the second roller 5. If after the adjustment is completed, there is a slight loose gap between the track 1 and the two walking rollers due to the uneven surface of the track 1 or the slight wear of the walking roller and the track 1 after a period of use, the two top screws 634 can be rotated to move the two top screws 634 seat body 611 inward, while pushing the spline petals 633 to slide in the second through hole toward the eccentric shaft 62. The spline petals 633 push the petal gear 631 to move slightly, thereby driving the entire eccentric shaft 62 to rotate slightly in the direction close to the track 1 with the top of the screw 632 as the axis, achieving fine-tuning of the angle between the eccentric shaft 62 and the handle seat 61, so that the second roller 5 is more closely aligned with the side wall of the track 1, ensuring the smoothness of the sliding and further ensuring the cutting accuracy. The coordinated arrangement of the locking component 64 and the fine-tuning component 63 in the utility model facilitates the rotation and locking of the handle seat 61, and is easy to operate.

[0065] After the first roller 4 and the second roller 5 are tightly clamped on both sides of the track 1, the second motor 251 is started, and the first worm 253 is driven to rotate through the first reducer 252, and the first worm 253 drives the first worm gear 254 to rotate, and the first worm gear 254 drives the swing arm 22 to rotate, thereby driving the saw blade 3 at one end of the swing arm 22 to rotate a certain angle with the other end of the swing arm 22 as the axis. The height of the saw blade 3 is adjusted according to needs, which is practical and reliable.

[0066] Finally, the first motor 241 and the third motor 261 are started at the same time. The first motor 241 drives the input gear 242 to rotate, the input gear 242 drives the idler gear 243 to rotate, the idler gear 243 drives the output gear 244 to rotate, and the output gear 244 drives the saw blade 3 to rotate. At the same time, the third motor 261 drives the second worm 263 to rotate through the second reducer 262, the second worm 263 drives the second worm gear 264 to rotate, and the second worm gear 264 drives the traveling gear 23 to rotate, and through the cooperation between the traveling gear 23 and the rack 8, the machine head 2 slides along the length direction of the track 1, and the saw blade 3 rotates to cut the cutting surface.

[0067] The above description is only a preferred embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
