[0001] This invention relates to the field of construction equipment technology, specifically a cutting device for manufacturing precast reinforced concrete frames. Background Technology
[0002] With the continuous progress of the times, the construction methods in the construction industry have become more and more diversified. Nowadays, more and more construction projects are using precast frame components to replace the previous cast-in-place concrete frame structures. This is because the use of precast frame components greatly saves the time and material costs of the project and can also reduce the pollution to the environment during construction. These precast frame components are produced in an integral molding manner and need to be cut and separated by a cutting device before they can be put into use.
[0003] Currently available cutting devices for manufacturing precast reinforced concrete frames can cut and separate precast frame components, but the part of the cutter head that comes into contact with the precast reinforced concrete frame component is easily worn during the cutting process, resulting in a short service life for the cutting device.

The lifting cutting device 7 and the water supply device 8 are arranged parallel to each other, with the lifting cutting device 7 located directly above the cutting channel 12. When the lifting cutting device 7 is cutting, the water supply device 8 supplies water to the contact surface between the lifting cutting device 7 and the precast reinforced concrete frame component, thereby reducing the wear of the blade in the lifting cutting device 7 and extending its service life.
[0031] The lifting and cutting device 7 includes a cutter 71, a lead screw 73, and a guide rod 74. The cutter 71 is used to cut precast reinforced concrete frame components. A second motor 72 is fixedly mounted on the outer surface of the cutter 71 via a bracket. The second motor 72 is located in the motor displacement channel 9. One end of the cutter 71 is connected to the lead screw 73 via its internal thread. The bottom end of the lead screw 73 is rotatably mounted on the top of the device base 1. The top end of the lead screw 73 passes through the first housing 2 and extends to its outer side, where it is fixedly connected to the output end of the first motor 4. The bottom end of the guide rod 74 is fixedly mounted on the top of the device base 1, and the top end of the guide rod 74 is fixedly mounted on the top of the inner cavity of the first housing 2. The other end of the cutter 71 is slidably mounted on the outer surface of the lead screw 73. With the first motor 4 in operation, the cutter 71 can be lowered to the surface of the precast frame via the lead screw 73. Then, the operator turns on the power of the second motor 72, and the cutter 71 cuts the precast frame. When encountering precast frames of different heights, the operator can control the cutting depth of the cutter 71 through the first motor 4, thus achieving the purpose of cutting the precast frame according to different needs.

[0033] Rotating rods 714 are rotatably mounted on both sides of the inner wall of the mounting hole 713. One end of the rotating rod 714 extends through the displacement base 711 to its outer side and is fixedly connected to the output end of the second motor 72. A buffer pad 712 is fixedly mounted on the bottom of the displacement base 711. The buffer pad 712 can buffer the impact force between the displacement base 711 and the device base 1. A cutter disc 715 is fixedly mounted on the outer surface of the rotating rod 714. The cutter disc 715 is located directly above the cutting channel 12 and is used for cutting. When the second motor 72 operates, the cutter disc 715, which contacts the surface of the prefabricated frame, rotates at high speed, thus achieving the purpose of cutting the prefabricated frame.
[0034] The cutter head 715 includes a cutter body 7151, which is fixedly mounted on the outer surface of the rotating rod 714. Limiting rings 7152 are fixedly installed at the center of both sides of the outer surface of the cutter body 7151. The limiting rings 7152 can prevent the cutter head 715 from shifting position during operation. Liquid conveying grooves 7153 are provided on both sides of the outer surface of the cutter body 7151. The liquid conveying grooves 7153 are used for liquid to flow from the outer surface of the cutter body 7151 to the end. Water seepage holes 7154 are provided on the outer surface of the cutter body 7151, and the water seepage holes 7154 penetrate the cutter body 7151 and extend to the other side. By opening a liquid delivery channel 7153 and a seepage hole 7154, the seepage hole 7154 is used to deliver liquid to the side of the cutter body 7151 away from the water supply device. When the water supply device 8 supplies water to the cutter disc 715, water will be supplied to the edge of the cutter disc 715 through the liquid delivery channel 7153 and the seepage hole 7154 to prevent excessive wear, thus extending the service life of the cutter disc 715.
[0035] Please see Figure 8-10 This invention provides a technical solution: the water supply device 8 includes a second housing 81, the bottom of which is fixedly installed on the top of the device base 1. An inlet pipe 82 is fixedly installed on the top of the second housing 81, used to input liquid into the second housing 81. The inlet pipe 82 penetrates the first housing 2 and extends to its outer side. A cap 83 is detachably installed on the top of the inlet pipe 82, and the cap 83 is compatible with the inlet pipe 82. The cap 83 can control the discharge of liquid through air pressure. A liquid outlet device 84 is fixedly installed at the bottom edge of the outer surface of the second housing 81, used for liquid transportation. The liquid outlet device 84 is located on the side of the outer surface of the second housing 81 facing the lifting cutting device 7. By setting the cap 83, when the cutting work is completed, the operator can reinstall the cap 83 back on the top of the inlet pipe 82. Liquid will no longer flow out from the liquid outlet device 84 due to atmospheric pressure, thus achieving the purpose of water supply on demand.
[0036] The liquid outlet device 84 includes an outlet pipe 841. One end of the outlet pipe 841 is fixedly installed on the outer surface of the second housing 81, and the other end of the outlet pipe 841 is fixedly installed with a liquid booster head 842. The liquid booster head 842 is used to increase the liquid pressure so that the liquid can flow out in a directional manner. The end of the liquid booster head 842 away from the outlet pipe 841 has an outlet port 843. Through the operation of the liquid booster head 842, the liquid in the second housing 81 will be transported to the designated position of the cutter head 715, thus achieving the purpose of directional liquid transport.
[0037] In use, the operator moves the device to the location of the precast concrete frame to be cut using the operating handle 3, turns on the power switch of the first motor 4, and lowers the cutter 71 to the top of the precast concrete frame component via the lead screw 73. Then, the operator turns off the power switch of the first motor 4, opens the cover 83, and pours water into the second housing 81 through the liquid inlet pipe 82. The water is then directed to the cutter head 715 through the liquid outlet device 84. At this time, the power of the second motor 72 is turned on, and the cutter head 715 cuts the precast concrete frame component. The operator pushes the cutting device in the direction to be cut using the operating handle 3. After cutting is completed, the power of the second motor 72 is turned off, and the cover 83 is placed on top of the liquid inlet pipe 82. The power switch of the first motor 4 is turned on again, and the cutter 71 is lifted upward to the inner cavity of the first housing 2 via the lead screw 73. Then, the power switch of the first motor 4 is turned off.
[0038] In the liquid delivery section, the cap 83 is removed from the top of the inlet pipe 82 and placed inside the operating handle 3. Water is poured into the second housing 81 through the inlet pipe 82. The water is then directed to the cutter head 715 through the outlet device 84. After the device has finished cutting, the cap 83 is put back on the top of the inlet pipe 82. At this time, the liquid will no longer spray out from the outlet device 84 due to atmospheric pressure.
[0039] In the water supply section of the cutter head, when liquid is sprayed onto the surface of the cutter disc 715 through the liquid outlet device 84, the liquid will be transported to the end of the cutter body 7151 through the liquid transport channel 7153. The liquid will also flow through the seepage hole 7154 to the side away from the liquid outlet device 84, and be transported to the end of the cutter body 7151 through the liquid transport channel 7153 on that side.
