Description

Technical Field

[0001] The invention relates to the technical field of manufacturing and cutting of reinforced concrete prefabricated frames, in particular to a cutting device for manufacturing reinforced concrete prefabricated frames. Background Art

[0002] Reinforced concrete formwork, as the core prefabricated unit of building components, is usually formed using standard molds during factory production. However, due to actual assembly errors, interface allowances, or structural splicing requirements, the formwork length often needs to be fine-tuned before installation. This is especially true at component assembly or joints. To ensure structural sealing and force balance, the ends of the precast concrete formwork need to be partially cut and trimmed to achieve precise dimensional matching. However, since concrete formwork is usually pre-embedded with steel bars, if the steel bars are accidentally touched during the cutting process, not only will the passivation protective film on the surface of the steel bars be damaged, leading to subsequent rust problems, but the formwork may also be cracked locally or the fracture surface is rough due to steel bar breakage or high-temperature friction. To avoid such problems, manual inspection of the distribution position and embedding depth of the steel bars is often used. Cutting is performed only after confirming that the concrete thickness in the end area is sufficient and the steel bars do not extend to the cutting area. If the length of one end is not enough to meet the adjustment requirements, the formwork needs to be flipped or moved, and the inspection and cutting are repeated at the other end. This process is cumbersome and inefficient. In addition, the inspection results are easily affected by human experience, which poses a risk of misjudgment and is not conducive to completing the formwork length adjustment operation efficiently and accurately. Existing Chinese patent publication number CN106738363B discloses a cutting machine capable of completely flattening concrete blocks. The device comprises an improved clamping assembly disposed on a base and a slidable pressure plate disposed on one side of the clamping assembly. After the concrete block is placed in a clamping groove and clamped by the clamping assembly, the pressure plate presses against the free end of the concrete block, thereby fixing the concrete by squeezing before cutting. However, this cutting method cannot address the problem of damage to the cut edge and cannot avoid the internal reinforcement structure of the concrete. Therefore, it is necessary to design a cutting device for manufacturing reinforced concrete prefabricated frames that is highly practical and can avoid causing damage to the internal structure during the cutting process of the reinforced concrete template.

[0014] See also Figure 1-6 The present invention provides a technical solution: a cutting device for manufacturing reinforced concrete prefabricated frames, comprising a base 1 and a control module, wherein an electric drive wheel 2 is fixedly connected to the lower side of the base 1, a track 3 is fixedly connected to the upper side of the base 1, and a cutting mechanism 4 and a detection mechanism 5 are provided on the upper right side of the track 3; The cutting mechanism 4 includes a connecting assembly and a cutting disc 406, a rotation speed detection module 409, and a power detection module 410 on the connecting assembly; The cutting disc 406 can be translated left and right relative to the base 1, and the cutting disc 406 can rotate to cut concrete during the movement. The speed detection module 409 can detect the speed of the cutting disc 406. The connecting component also includes a first slide 401. The lower side of the first slide 401 is slidably connected to the upper side of the track 3. The upper side of the first slide 401 is fixedly connected to the mounting bracket 402. The right side of the base 1 is fixedly connected to the moving motor 403. The output end of the moving motor 403 is fixedly connected to the threaded rod 404. The outer wall of the threaded rod 404 is threadedly connected to the middle inner wall of the first slide 401. The upper side of the mounting bracket 402 is slidably connected to the cutting motor 405, and the cutting motor 405 is electrically connected to the control module. The output end of the cutting motor 405 is fixedly connected to the inner wall of the cutting disc 406. A shield 407 is provided on the upper side of the cutting disc 406. The outer wall of the shield 407 is fixedly connected to the outer wall of the cutting motor 405. The outer wall of the shield 407 is also fixedly connected to a water pipe rack 408. The lower end of the water pipe rack 408 faces the outer wall of the cutting disc 406. A speed detection module 409 is provided on the shield 407, and the detection end of the speed detection module 409 faces the cutting disc 406. A power detection module 410 is provided on the upper side of the cutting motor 405. The power detection module 410 can detect the power consumption of the cutting motor 405, and the speed detection module 409 and the power detection module 410 are both electrically connected to the control module; When the present invention is used, it should be arranged on one side of the reinforced concrete prefabricated frame placement area to ensure that the cutting disc 406 is located on the upper part of one side of the prefabricated frame. When the prefabricated frame needs to be cut, the electric drive wheel 2 is started to move the present invention to the template to be cut in the order of the prefabricated templates. The cutting motor 405 is started by the control module to make the cutting motor 405 drive the cutting disc 406 to rotate at high speed. At the same time, the moving motor 403 drives the threaded rod 404 to rotate. Since the outer wall of the threaded rod 404 is threadedly connected to the inner wall of the first slide 401, the moving motor 403 drives the first slide 401 and the mounting frame 402 to move during the rotation of the threaded rod 404, thereby making the cutting disc 406 cut the concrete frame while moving, completing the trimming and cutting work of the finished product. During the cutting process, the water supply device is connected to the upper side of the water pipe rack 408 through the water pipe, so that the water flow flushes the cutting disc 406, thereby completing the cooling. The detection mechanism 5 includes a movable component and an ultrasonic metal detection module 506 on the movable component. The ultrasonic metal detection module 506 can be translated left and right relative to the base 1. The ultrasonic metal detection module 506 can detect the steel structure inside the concrete. The detection mechanism 5 includes a second slide 501. The upper left part of the second slide 501 is fixedly connected with a connecting rod 502. The other end of the connecting rod 502 is provided with a socket. The inside of the socket is plugged with an insertion rod 503. The lower end of the insertion rod 503 is fixedly connected to a fixed cover 504. The upper surface of the fixed cover 504 is fixedly connected with a first spring 505. The upper end of the first spring 505 is fixedly connected to the outer wall of the connecting rod 502. Two ultrasonic metal detection modules 506 are provided on the fixed cover 504. The two ultrasonic metal detection modules 506 are respectively arranged on the middle rear side of the fixed cover 504 and the right front part of the fixed cover 504. A water inlet pipe 507 is fixedly connected to the upper surface on the left side. The detection mechanism 5 also includes an electric telescopic rod 508, one end of the electric telescopic rod 508 is fixedly connected to the outer wall of the mounting bracket 402, and the other end of the electric telescopic rod 508 is fixedly connected to a fixing ring 509. The inner wall of the fixing ring 509 is fixedly connected to the outer wall of the cutting motor 405. The lower side of the fixed cover 504 is a cavity structure, and the lower right side of the fixed cover 504 is opened. The lower end of the water inlet pipe 507 is connected to the interior of the cavity on the lower side of the fixed cover 504. The lower end of the ultrasonic metal detection module 506 is located inside the lower cavity of the fixed cover 504. The lower side of the second slide 501 is slidably connected to the upper side of the outer wall of the track 3, and the second slide 501 is connected to the track 3 through a linear motor. The linear motor at the connection between the second slide 501 and the track 3, as well as the ultrasonic metal detection module 506 and the electric telescopic rod 508 are all electrically connected to the control module; Before the cutting operation of this device, the linear motor at the connection between the second slide 501 and the track 3 can be started through the control module, thereby making the second slide 501 slide from right to left, pulling the fixed cover 504 to move over the upper part of one side of the concrete frame. In this process, since the left side of the fixed cover 504 is set as an arc surface, after it moves to the upper side of the concrete template, the elastic compression of the first spring 505 on the fixed cover 504 causes the lower side of the fixed cover 504 to be in close contact with the upper side of the concrete template, and is connected to the upper side of the water inlet pipe 507 through the external water supply device, so that water flows continuously into the lower side of the fixed cover 504 through the water inlet pipe 507. Since the fixed cover 504 continues to move and the right side of the fixed cover 504 is set as an opening, the water flow will form a water film between the ultrasonic metal detection module 506 and the concrete template, so that the ultrasonic metal detection module 506 can detect whether there are steel bars in the concrete template. When there are no steel bars inside the concrete template, the cutting disc 406 successfully completes the cutting operation. When there are steel bars inside the concrete formwork, the electric telescopic rod 508 can be started to push and pull the fixing ring 509 according to actual needs, so that the fixing ring 509 drives the cutting motor 405 and the cutting disc 406 to move, thereby adjusting the position of the cutting disc 406 to cut the concrete formwork. If the cutting length is insufficient, the concrete formwork can be turned over and supplemented from the other end; The detection mechanism 5 also includes a limit rod 510, the lower end of the limit rod 510 is fixedly connected to the right side of the upper surface of the second slide 501, the outer wall of the limit rod 510 is provided with a fixed sleeve 512, the upper surface of the second slide 501 is also fixedly connected to a second spring 511, the upper end of the second spring 511 is fixedly connected to the lower surface of the fixed sleeve 512, the outer wall of the fixed sleeve 512 is fixedly connected to the outer wall of the fixed cover 504 via a connecting arm 513, the inner wall of the fixed sleeve 512 is fixedly connected to a slitting motor 514, the output end of the slitting motor 514 is fixedly connected to a slitting blade 515, the rear side of the slitting blade 515 is in the same plane as the front side of the fixed cover 504, and the slitting motor 514 is electrically connected to the control module, and the lower side of the slitting blade 515 is lower than the lower surface of the fixed cover 504; After the fixed cover 504 moves to the surface of the concrete formwork, its lower side contacts the upper surface of the concrete formwork, causing the fixed cover 504 to drive the fixed sleeve 512 to move through the connecting arm 513, thereby adjusting the height of the slitting motor 514. At the same time, when the ultrasonic metal detection module 506 is detecting and moving the steel bar, the slitting motor 514 can be started by the control module, and the slitting motor 514 can drive the slitting blade 515 to rotate, so that the slitting blade 515 cuts and grooves the upper side of the concrete formwork. At the same time, the water discharged from the right side of the fixed cover 504 lubricates and cools the slitting blade 515, so that the slitting blade 515 grooves the concrete surface and completes pre-crack guidance, thereby preventing the concrete slab from sagging due to gravity due to only the end being connected to the mother body as the cutting proceeds, resulting in irregular fractures and damaging the entire concrete formwork. When the cutting disc 406 performs main line cutting later, the crack will be naturally guided along this path instead of being torn. During use of the present device, the grooves cut by the slitting blade 515 on the surface of the concrete formwork allow water to penetrate into the interior of the concrete formwork faster, thereby reducing the disintegration and damage caused by cutting during the subsequent cutting process by the cutting disc 406 due to the water content in the concrete. During the process of the cutting disc 406 cutting the concrete formwork, its speed is detected in real time by the speed detection module 409, and the energy consumption of the cutting disc 406 is monitored by the power detection module 410. The control module calculates the data of the power detection module 410 and the speed detection module 409 to form a regular ratio. When the power increases or the speed of the speed detection module 409 drops rapidly, the ratio changes. When the change exceeds the threshold, a notification is issued through the control module and the cutting motor 405 is stopped, thereby avoiding the situation where the cutting disc 406 moves out of the detection range of the ultrasonic metal detection module 506 or the ultrasonic metal detection module 506 drifts due to improper operation, thereby achieving the effect of protecting the steel bars inside the concrete formwork and avoiding the situation where the high temperature damages the concrete formwork when the cutting disc 406 cuts the steel bars.
