[0002] Electric wall cutting machines are construction equipment used to cut concrete components, walls, roads, etc. They have the advantages of precise cutting, high efficiency, and safety without risk. After the precast concrete wall is installed, it can be used to adjust the original design, such as changing the position of the door opening or the size of the window, thereby cutting the wall to adapt to the new design requirements or site requirements.

[0003] However, in practical applications, the wall is still mainly cut by manually operating the cutting machine. During the cutting process, not only is a large amount of dust and inhalable particulate matter generated, but the construction quality is also directly affected by the large observation error of the construction personnel.

[0004] In addition, the internal structure of ordinary cement walls is quite complex. Not only do they contain reinforced concrete structures, but some factory buildings also contain high-voltage electrical or water lines, which can easily cause injury to construction workers.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0037] Please refer to this as well. Figures 1-5 This utility model discloses a wall cutting machine, mainly comprising a comprehensive transmission box 1, a guide assembly 3, and a cutting swing arm 7. The cutting swing arm 7 is used to drive the circular saw to swing, thereby adjusting the cutting depth of the circular saw. A junction box 4 is installed on the top of the comprehensive transmission box 1. The junction box 4 outputs drive current and control signals to the drive unit through a terminal block 5, thereby using the drive unit to drive the equipment. In addition, a pair of roller locking mechanisms 2 are installed on both sides of the comprehensive transmission box 1. The roller locking mechanisms 2 can be embedded in both sides of the guide assembly 3. The front of the comprehensive transmission box 1 is equipped with traveling wheels 8, which are driven to rotate by the drive unit. The traveling wheels 8 can drag the comprehensive transmission box 1 to move, thereby allowing it to move along the length direction of the guide assembly 3.

[0038] In this embodiment, the traveling wheel 8 is connected to the traction component 9 via a transmission connection. Specifically, the traveling wheel 8 is a gear, and the traction component 9 is a rack. The traveling wheel 8 and the traction component 9 are connected by gear meshing and transmission. Alternatively, as another optional technical solution, the traveling wheel 8 can also be a winch, and the traction component 9 can be a steel wire rope. By winding the steel wire rope onto the winch, the position of the integrated transmission box 1 is moved by rotating the winch.

[0039] In some embodiments, such as Figure 2 The drive unit is installed on the integrated transmission box 1 and is connected to the junction box 4. The drive unit mainly includes a travel motor A1, a cutting motor A2 and a feed motor A3. The travel motor A1 is connected to the travel wheel 8, the feed motor A3 is connected to the cutting arm 7, and the cutting motor A2 is connected to the circular saw installed on the cutting arm 7.

[0040] Furthermore, the travel motor A1, cutting motor A2, and feed motor A3 are all servo motors and are connected to the junction box 4. A microcontroller is installed inside the junction box 4, and the microcontroller is connected to the torque and speed sensor 752, which in turn is connected to the travel motor A1, cutting motor A2, and feed motor A3 respectively. In addition, an electromagnetic brake is installed on the feed motor A1, which is connected to the microcontroller. The microcontroller sends an electrical signal to drive the electromagnetic brake to mechanically brake the feed motor A2. Therefore, when the circular saw cuts into the reinforcing steel in the wall, the electromagnetic brake can lock the feed motor A2, thus preventing the cutting arm 7 from rebounding.

[0041] In this embodiment, as Figure 5 The end of the cutting arm 7 is coaxially connected to the integrated transmission box 1. The feed motor A2 is adapted to drive the cutting arm 7 to swing through the integrated transmission box 1. Furthermore, a protective cover 6 is installed on the outside of the cutting arm 7 to prevent debris and coolant from splashing out.

[0042] In one specific embodiment of this utility model, the cutting arm 7 includes a rotary arm 71 and a transmission mounting groove 73. A gear transmission mechanism 74 is installed inside the transmission mounting groove 73. The gear transmission mechanism 74 adjusts the reduction ratio to increase the output torque by coordinating gears of different sizes. The cutting motor A2 is connected to the cutter head 75 through the gear transmission mechanism 74. In this embodiment, the transmission mounting groove 73 is located inside the rotary arm 71, and a cooling groove 72 is provided at the tail end of the rotary arm 71. Cooling liquid is introduced into the cooling groove 72 to cool the gear transmission mechanism 74 in the transmission mounting groove 73. The cutter head 75 is installed at the head end of the rotary arm 71 and is used to clamp and fix the circular saw to cut the wall.

[0043] In this embodiment, the cutter head 75 includes a rotating shaft 751 and a torque and speed sensor 752. The tail end of the rotating shaft 751 is connected to a gear transmission mechanism 74, which is adapted to drive the rotating shaft 751 to rotate. The head end of the rotating shaft 751 is coaxially connected to a turntable 753. A torque and speed sensor 752 is also provided on the turntable 753 to measure the torsion angle of the rotating shaft 751 and thus obtain the torque of the cutter head 75. The torque and speed sensor 752 transmits signals to the microcontroller in real time. When the circular saw cuts metal or stone, the torque of the cutter head 75 increases instantaneously. At this time, the microcontroller can reduce the speed of the motor by adjusting the frequency of the inverter, thereby reducing the wear of the circular saw.

[0044] In a specific embodiment of this utility model, the guide assembly 3 includes a profile 31, a guide rail 32, and a base 33. The base 33 is installed at the bottom of the profile 31. A pair of guide rails 32 are symmetrically arranged on both sides of the profile 31, and a roller locking mechanism 2 is slidably arranged on the guide rails 32. The roller locking mechanism 2 includes a frame 21, a handle 22, a locking pin 23, and rollers 24. A pair of rollers 24 are arranged on both sides of the frame 21. The pair of rollers 24 are embedded in the guide rails 32. The rollers 24 are coaxially connected to the handle 22. The rollers 24 are suitable for positioning by the locking pin 23, thereby preventing the rollers 24 from becoming loose from the guide rails 32.

[0045] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
