Description

Technical Field

[0001] The utility model relates to the technical field of processing devices, in particular to a cutting device for construction engineering. Background Art

[0002] In construction projects, cutting devices are needed to cut metal or wooden panels, steel pipes and other construction materials so that the construction materials can reach the length required by the on-site construction environment and on-site construction.

[0003] Reference publication number "CN114603649B" discloses a building material cutting device for construction projects. The device describes: "Breaking the traditional horizontal cutting method, a design scheme for vertically cutting wood is adopted. Taking into account the technical issue of difficulty in clamping a wood block when one end is fixed, Pascal's law is employed to secure the lower end of the block through reciprocating hydraulics. Combined with the power of the block's lifting, this achieves a pre-set design whereby the upper end automatically flips and secures after the block is raised. Furthermore, the Coanda effect is utilized during the cutting process to absorb and filter wood debris generated during the cutting process. This not only reduces the horizontal space occupied by cutting long strips of wood, but also improves the cleanliness of the working environment."

[0004] During the implementation of this patent, the applicant discovered the following technical problems:

[0005] When cutting building materials using a cutting device, in order to ensure that the vibration generated during the cutting process does not cause the material to move, it is necessary to manually fix it or use a clamping mechanism to fix it. Although the clamping mechanism can avoid the hidden danger of injury to the hand-held fixation caused by the rotation of the cutter disc, the clamping needs to be adjusted according to the size of the material being cut; in addition, when changing the cutting position, it is necessary to manually push the material to change its position on the cutting device.

[0006] Therefore, it is necessary to propose a cutting device for construction engineering to provide a new technical solution for solving the above-mentioned technical problems. Utility Model Content

DETAILED DESCRIPTION

[0033] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments 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 should fall within the scope of protection of the present invention.

[0034] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figure 1 As shown, a cutting device for construction engineering comprises: a platform 1, a frame 2 fixed to the top of the platform 1, a lifting mechanism 4 provided on the frame 2, and a cutting mechanism 3 provided on the lifting mechanism 4. The lifting mechanism 4 drives the cutting mechanism 3 to move vertically, that is, to move toward or away from the platform 1, so as to cut metal or wooden plates, steel pipes, or other construction materials placed on the platform 1;

[0036] The cutting mechanism 3 is provided with a first positioning mechanism 5 and a second positioning mechanism 6 (the second positioning mechanism 6 Figure 1 (not shown in the figure), the bottom ends of the first positioning mechanism 5 and the second positioning mechanism 6 are flush and on the same horizontal line, and the position of the bottom ends is lower than the lowest point of the lifting mechanism 4, so that before the cutting mechanism 3 moves downward to cut the material on the platform 1, the bottom ends of the first positioning mechanism 5 and the second positioning mechanism 6 will first contact the material, and after the cutting mechanism 3 continues to descend, the bottom ends of the first positioning mechanism 5 and the second positioning mechanism 6 will be compressed and contracted, but at the same time, the downward pressure provided to the material will become greater and greater. In this way, during the cutting process, the bottom end of the cutting mechanism 3 (i.e., the cutting line of the cutting mechanism 3) will gradually be flush with the bottom ends of the first positioning mechanism 5 and the second positioning mechanism 6, until the bottom end of the cutting mechanism 3 is lower than the bottom ends of the first positioning mechanism 5 and the second positioning mechanism 6, at which time the cutting work of the material on the platform 1 is completed.

[0037] like Figure 2 As shown, the cutting mechanism 3 includes a first motor 31, a knife cover 32, a knife disc 33 and a support plate 34. The knife disc 33 is installed in the knife cover 32, and the support plate 34 is fixed to the middle of both sides of the knife cover 32. The first motor 31 is fixed on one side of the support plate 34. The output end of the first motor 31 is connected to the knife disc 33. By connecting the first motor 31 to electricity to rotate it, the rotation of the first motor 31 drives the knife disc 33 in the knife cover 32 to rotate at a high speed. As the knife disc 33 contacts the preset cutting line on the material, the material is cut.

[0038] like Figure 3 As shown, the lifting mechanism 4 includes two first connecting plates 41, two second connecting plates 42, two hinge blocks 43, a transmission shaft 44 and a hand wheel 45. The bottom ends of the two first connecting plates 41 are rotatably connected to the support plate 34, the top ends of the two first connecting plates 41 are rotatably connected to the bottom ends of the two hinge blocks 43, the bottom ends of the two second connecting plates 42 are rotatably connected to the top ends of the two hinge blocks 43, and the top ends of the two second connecting plates 42 are rotatably connected to the frame 2 through mounting seats. The transmission shaft 44 is arranged between the two hinge blocks 43, and the hand wheel 45 is fixed to one end of the transmission shaft 44.

[0039] The transmission shaft 44 includes two screws and a short shaft. The two screws are connected to the two ends of the short shaft in opposite directions. The two screws are respectively threadedly connected to the screw holes provided on the two hinge blocks 43.

[0040] When in use, the transmission shaft 44 is driven to rotate by the hand wheel 45. Since the transmission shaft 44 has two threaded sections with opposite spiral directions, and the two threaded sections are respectively threadedly connected to the two hinge blocks 43, at the same time, under the connection restriction of the upper and lower first connecting plates 41, the hinge block 43 does not rotate with the rotation of the transmission shaft 44, but moves on the transmission shaft 44. Specifically, the two hinge blocks 43 move toward each other, so that the positions of the two hinge blocks 43 on the transmission shaft 44 are shortened or expanded. In this way, the first connecting plate 41 and the second connecting plate on the hinge block 43 are connected. The inclination angle of the plate 42 will change. Specifically, under the premise that the distance between the two hinge blocks 43 is shortened, the first connecting plate 41 and the second connecting plate 42 gradually change upward to a vertical shape. Under this shape change, the connection point of the first connecting plate 41 on the cutting mechanism 3 and the connection point of the second connecting plate 42 on the frame 2 will be separated, that is, the cutting mechanism 3 will be driven to descend downward away from the frame 2 until the material on the platform 1 is cut. After cutting, the lifting mechanism 4 reverses the above steps to drive the cutting mechanism 3 to move upward and separate from the material to be cut.

[0041] like Figure 4 As shown, the first positioning mechanism 5 includes a pressure plate 51, a damping rod 52 and a pressure shaft 7. The pressure plate 51 is rotatably connected to the bottom end of one side of the support plate 34. The bottom end of the female rod of the damping rod 52 is rotatably connected to the pressure plate 51. The telescopic end of the damping rod 52 is rotatably connected to the support plate 34. The pressure shaft 7 is rotatably connected to the bottom end of the pressure plate 51.

[0042] Under the connection of the damping rod 52, the position of the pressure shaft 7 on the pressure plate 51 will be lower than the cutter disc 33, so that the pressure shaft 7 will first contact the material before preparing for cutting. However, as the cutting mechanism 3 descends, the pressure shaft 7 rotates to one side at the connection point with the support plate 34, and at the same time squeezes the telescopic end of the damping rod 52, so that the telescopic end of the damping rod 52 retracts into the mother rod part, allowing the position where the pressure shaft 7 contacts the material to move to one side, but the downward pressure provided by the pressure shaft 7 on the material becomes greater and greater to fix the material.

[0043] like Figure 5 As shown, the second positioning mechanism 6 has the same function as the first positioning mechanism 5 but has a different structure. The second positioning mechanism 6 includes a sleeve plate 61, a telescopic plate 62, a spring 63 and a pressure shaft 7. The sleeve plate 61 is fixed to the bottom end of the other side of the support plate 34, and the sleeve plate 61 is sleeved outside the telescopic plate 62. The pressure shaft 7 is rotatably connected to the bottom end of the telescopic plate 62 that leaks out of the sleeve plate 61. The top end of the spring 63 is fixed to one side of the sleeve plate 61 through a fixing block, and the bottom end of the spring 63 is also fixed to one side of the portion of the telescopic plate 62 that leaks out of the sleeve plate 61 through a fixing block.

[0044] The telescopic plate 62 located in the sleeve plate 61 is connected to the spring 63, and the pressure shaft 7 on the telescopic plate 62 is flush with the pressure shaft 7 on the first positioning mechanism 5, so that the pressure shaft 7 will first contact the material before preparing for cutting. However, as the cutting mechanism 3 descends, the telescopic plate 62 compresses the spring 63 and retracts into the sleeve plate 61, causing the pressure shaft 7 on the telescopic plate 62 to move upward, but at the same time, the downward pressure provided by the pressure shaft 7 on the material becomes greater and greater, so that the material is fixed. In some embodiments, the cutting mechanism 3 has two sets of second positioning mechanisms 6 arranged opposite to each other.

[0045] like Figure 6 As shown, a moving mechanism 8 is provided in the platform 1, and the moving mechanism 8 is used to transmit objects between the pressure shaft 7 of the first positioning mechanism 5 and the second positioning mechanism 6 and the platform 1 to drive the building materials forward or backward to facilitate secondary cutting of the building materials.

[0046] like Figure 6 As shown, the moving mechanism 8 includes at least two rotating shafts 82, at least one set of belt transmission structure and a second motor 85, the roller 81 is fixed to the outside of the rotating shaft 82, the roller 81 is fixedly sleeved with a rubber layer, the belt transmission structure is arranged between at least two rotating shafts 82, the second motor 85 is fixed to one of the rotating shafts 82 and leaks out of one end of the platform 1; a set of belt transmission structure includes a driving wheel 83, a driven wheel 84 and a synchronous belt 86, the driving wheel 83 is fixed to the rotating shaft 82 connected to the second motor 85, and the driven wheel 84 is fixed to the other rotating shaft 8 2, a synchronous belt 86 is sleeved between the driving pulley 83 and the driven pulley 84; in some embodiments, the number of rollers 81, rotating shafts 82 and belt transmission structures includes but is not limited to two and one group as described above, for example, the number of rollers 81 and rotating shafts 82 can be set in an even number of increments, and the belt transmission structure can be two groups and more, which are adaptively increased according to the number of rollers 81 and rotating shafts 82. In some embodiments, the platform 1 is exposed from the roller 81 through the through slot opened, and the roller 81 is flush with the through slot of the platform 1.

[0047] During use, under the premise that the pressure shaft 7 of the first positioning mechanism 5 and the second positioning mechanism 6 contacts the material, but the cutter disc 33 does not contact the material, the second motor 85 is controlled to rotate to drive one of the rotating shafts 82 to rotate, and the rotating shaft 82 drives the driving wheel 83 thereon to rotate, and the driving wheel 83 drives the driven wheel 84 through the synchronous belt 86. The rotation of the driven wheel 84 causes the rotating shaft 82 thereon to also rotate, and the roller 81 on the two rotating shafts 82 also starts to rotate. Since a rubber layer is fixedly sleeved on the roller 81, the rubber layer on the roller 81 will be higher than the platform 1. However, after the material to be cut is placed on the platform 1, the rubber layer will be squeezed, so that the rubber layer and the material form a surface contact and generate increased contact friction. In this way, as the rubber layer on the roller 81 rotates, the material is driven to move to one side to facilitate secondary cutting of the building material.
