Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of aerated concrete blocks, and more specifically, relates to a transverse cutting device for autoclaved aerated concrete. Background Technology
[0002] Autoclaved aerated concrete (AAC) blocks are a lightweight building material. Their main characteristics include a wide availability of raw materials and advantages over traditional clay bricks, such as sound insulation, heat insulation, fire resistance, and light weight. AAC is made by mixing materials such as lime, cement, and fly ash, which are then allowed to harden and form a large blank. This blank is then demolded, cut into shape, and finally autoclaved.
[0003] Currently, autoclaved aerated concrete (AAC) cross-cutting machines in the industry typically use electric motors for lifting. The lifting device is positioned at the top, with four vertical guide columns, and a reducer drives a chain to raise and lower the cutting mechanism. However, due to the heavy load on the cutting mechanism, a high-power motor is required during lifting, increasing energy consumption. Furthermore, the heavy load on the cutting mechanism causes the chain to experience greater tensile stress and wear, which is detrimental to its service life.
[0004] A search revealed a patent, CN205552822U, which discloses a cross-cutting machine for aerated concrete billets. This application includes a pair of gantry frames spaced apart, a crossbeam fixed to the upper end of the gantry frames, and a cross-cutting device located between the gantry frames. The crossbeam is equipped with a lifting device to raise and lower the cross-cutting device. The cross-cutting device includes a cross-cutting frame, a cross-cutting swing mechanism for cutting the billet located below the cross-cutting frame and connected to it, linear bearings at two corners along the length of the cross-cutting frame, and guide sleeves at the other two corners along the length of the cross-cutting frame. Linear guide rails, slidingly engaged with the linear bearings, are located on the inner side of the gantry frame columns, and guide shafts, slidingly engaged with the guide sleeves, are located on the inner side of the guide sleeves. This application uses the combination of linear bearings and linear guide rails, and guide sleeves and guide shafts, to guide the raising and lowering of the cross-cutting device to cut the concrete billet, effectively preventing shaking and vibration during the raising and lowering of the cross-cutting frame, thus improving the stability of the raising and lowering and the cutting quality.
[0005] For example, patent CN218227139U discloses an aerated concrete cross-cutting machine. This application includes a lifting device and a cutting frame connected thereto. The lifting device drives the cutting frame to move vertically. The lifting device is mounted on a mounting frame and includes a lifting transmission device and a lifting drive. The lifting drive is located at the center point of the cutting frame. An even number of lifting transmission devices are symmetrically distributed around the center point. The lifting drive drives the lifting transmission devices to rotate, causing the cutting frame to move up and down. The main purpose of this application is to ensure that the load on both sides of the lifting drive is consistent, effectively balancing the load forces on both sides. When the lifting drive lifts and lowers the cutting frame, it can reduce unnecessary off-center loading during operation and effectively avoid causing additional vibration.
[0006] The aforementioned applications all involve the optimized design of aerated concrete cross-cutting machines, which can effectively improve the stability of the cross-cutting device system. However, the problem of increased motor energy consumption due to the large load on the cutting mechanism has not been effectively solved. Utility Model Content

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0037] The present invention will be further described below with reference to specific embodiments.
[0038] like Figure 1 As shown, this embodiment of an autoclaved aerated concrete (AAC) cross-cutting device includes a frame 100, a lifting mechanism 200, a cutting structure 300, and a counterweight mechanism 400. The lifting mechanism 200 is mounted on the frame 100 and drives the cutting structure 300 to move up and down. The cutting structure 300 is also mounted on the frame 100 and is used to cut the blank to be cut. The counterweight mechanism 400 is dynamically connected to the cutting structure 300 and is used to counterweight the cutting structure 300, reducing the power required for lifting the cutting structure 300 and thus reducing the load on the lifting mechanism 200.
[0039] Specifically, such as Figure 2 As shown, the counterweight mechanism 400 includes a pulley 410 and a traction rope 420. The pulley 410 is mounted on the frame 100, and one end of the traction rope 420 is connected to the cutting structure 300, while the other end passes over the pulley 410 and is connected to the counterweight block 430.
[0040] The autoclaved aerated concrete (AAC) cross-cutting device of this embodiment can effectively reduce the power required for the lifting of the cutting structure 300 by setting up a counterweight mechanism 400, thereby saving energy.
[0041] In some embodiments, the frame 100 includes a set of vertical frames 110 and a horizontal frame 120 located on top of the vertical frames 110; wherein both the vertical frames 110 and the horizontal frame 120 are rectangular frame structures. The cutting structure 300 is slidably mounted on the outer wall of the corresponding vertical frame 110 via linear guide pairs. These linear guide pairs are existing technologies, such as guide rail slider mating, guide rod guide sleeve mating, or guide rod guide groove mating, etc., and are not specifically limited here.
[0042] In some embodiments, the counterweight mechanism 400 is provided in two sets, respectively for applying counterweight from both ends of the cutting structure 300. Simultaneously, the counterweight block 430 of each set of counterweight mechanisms 400 is disposed within the inner cavity of the vertical frame 110. The two columns of the vertical frame 110 can limit the counterweight block 430 to a certain extent, preventing it from swaying during lifting and lowering, thus affecting its stability.
[0043] Furthermore, the counterweight 430 and the inner wall of the vertical frame 110 are in a sliding fit to further improve the stability of the counterweight 430 during the lifting process.
[0044] In some embodiments, the horizontal frame 120 has an extension section 130 on its side wall near the cutting structure 300. There are two extension sections 130, located near the ends of the horizontal frame 120, and the extension direction of each extension section 130 is towards the cutting structure 300.
[0045] Meanwhile, pulleys 410 are provided on both end walls of the extension section 130 and the horizontal frame 120. That is, each set of counterweight mechanisms 400 is equipped with two pulleys 410, one located on the extension section 130 and the other located on the end walls of the horizontal frame 120 and the corresponding extension section 130.
[0046] This embodiment of the autoclaved aerated concrete (AAC) cross-cutting device, through the extension section 130, allows for convenient adjustment of the position of the traction lifting points, ensuring that the two traction lifting points are symmetrically distributed around the center of gravity of the cutting structure 300, thereby preventing eccentric loading. Simultaneously, the extension section 130 also allows the traction lifting points and chain lifting points to be staggered, preventing interference between the traction rope 420 and the transmission chain 220. Here, the traction lifting point refers to the lifting point on the cutting structure 300 used to connect to the traction rope 420; the chain lifting point refers to the lifting point on the cutting structure 300 used to connect to the transmission chain 220.
[0047] refer to Figure 3 As shown, in some embodiments, the lifting mechanism 200 includes a drive source 210 and a transmission chain 220. The drive source 210 is located on the top of the horizontal frame 120 near the cutting structure 300. Preferably, the drive source 210 is a motor and is located at the middle position of the side wall of the horizontal frame 120.
[0048] A drive shaft 230 extending along the sidewall is connected to each side of the drive source 210. The drive shaft 230 is rotatably mounted on the horizontal frame 120 via a bearing 260. A first sprocket 240 is located at the end of the drive shaft 230 away from the drive source 210, and this first sprocket 240 is positioned between two pulleys 410 of the same counterweight mechanism 400. A second sprocket 250 is located near the bottom of the vertical frame 110. One end of the drive chain 220 is connected to the top of the cutting structure 300, and the other end passes sequentially around the first sprocket 240 and the second sprocket 250 before connecting to the bottom of the cutting structure 300.
[0049] This embodiment of the autoclaved aerated concrete (AAC) cross-cutting device, through the setting of the counterweight mechanism 400, allows for the offsetting of part of the lifting force by increasing or decreasing the weight of the counterweight block 430, regardless of the self-weight of the cutting device. This effectively reduces the power of the motor and saves energy. Simultaneously, it significantly reduces the lifting load on the transmission chain 220, which helps extend its service life.
[0050] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the figures shown are only one embodiment of the present invention; the actual structure is not limited thereto. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
