Description

Technical Field

[0001] The utility model relates to the technical field of infrastructure equipment, in particular to a cutting device for foam bricks used in traffic infrastructure. Background Art

[0002] Foam bricks have excellent compressive properties: their compressive strength exceeds 0.5 MPa, reaching a maximum strength of over 10.5 MPa. They resist cracking and have a long service life. Foam bricks are also made from a variety of raw materials. Foam cement bricks are made by mixing small foam particles with cement. They are lightweight, heat-insulating, sound-insulating, and fire-resistant. Their small diameter significantly reduces costs, making them ideal for non-load-bearing walls. Bricks are generally fixed in size, but certain building locations require varying brick sizes. To ensure the bricks are flat and the right size, a brick cutter is used.

[0003] Existing brick cutters are divided into manual and electric types according to the power source. Since electric brick cutters require power to drive and are noisy and dusty, manual brick cutters are mostly used to cut bricks on construction sites to ensure the convenience of using brick cutters. However, when using existing manual brick cutters, in order to ensure the instability of the blades, the blades are mostly connected to the bracket, resulting in the brick cutters only being able to cut right-angled bricks. People also need to use brick knives to correct the bricks into inclined-angle bricks, which greatly reduces the speed of bricklaying construction. At the same time, the existing brick cutters usually judge the size of the cut bricks with the naked eye, resulting in the cut bricks being of different sizes, affecting the use of workers. Therefore, there is a need for a cutting device for foam bricks for transportation infrastructure to solve this problem. Utility Model Content

[0028] Furthermore, the downward pressure cutting assembly 51 includes a support frame 511, which is fixedly installed on the top of the cutting table 1.

The side of the downward pressure plate 516 is rotatably connected to the third connecting rod 515, and the third connecting rod 515 is movably connected to the second connecting rod 514 and the first connecting rod 513, so that pressing or lifting the pressure rod 512 drives the downward pressure plate 516 to lift or press down, thereby ensuring the cutting requirements.

[0029] Furthermore, the rotation adjustment component 52 includes a movable groove 521, which is opened inside the lower pressure plate 516, and a second threaded rod 522 is provided on the outside of the movable groove 521, and the second threaded rod 522 is rotatably connected to the lower pressure plate 516, and a knob 523 is fixedly installed on the left end of the second threaded rod 522, and a rack 524 is installed on the external thread of the second threaded rod 522, and a gear 525 is rotatably installed inside the end of the lower pressure plate 516 away from the support frame 511, and the gear 525 is meshed with the rack 524, and the gear 525 extends to the bottom end of the lower pressure plate 516 and is fixedly installed with a rotating shaft 526, and a cutter head 527 is fixedly installed at the bottom of the rotating shaft 526, and the angle of the cutter head 527 can be adjusted to facilitate the cutting of different brick materials.

[0030] Furthermore, the first connecting rod 513 , the second connecting rod 514 and the third connecting rod 515 are each in two groups and are symmetrically distributed on both sides of the pressure rod 512 , so as to facilitate the lifting and pressing down of the lower pressure plate 516 .

[0031] Embodiment 2:

[0032] See also Figure 1-3 , and combined with Example 1, it is further obtained that the measuring and fixing mechanism 4 includes a measuring slot 41, the measuring slot 41 is opened at the top of the cutting table 1, the outside of the measuring slot 41 is fixedly installed with a first threaded rod 42, the outside of the first threaded rod 42 is slidably connected to a limit plate 43, the outside of the first threaded rod 42 is threadedly installed with a front fixing ring 44 and a rear fixing ring 45, the middle of the measuring slot 41 is fixedly installed with a scale 46, and the scale 46 is slidably connected to the limit plate 43, the top of the cutting table 1 is fixedly installed with a fixing plate 47, the back of the fixing plate 47 is fixedly installed with an electric push rod 48, the output shaft of the electric push rod 48 extends to the front end of the fixing plate 47 and is fixedly installed with an extrusion plate 49, which is convenient for measuring the length of the bricks to be cut and fixing the bricks for convenient cutting.

[0033] Furthermore, there are two groups of first threaded rods 42 , which are symmetrically distributed on both sides of the scale 46 with the scale 46 as the axis, so as to ensure the fixation of the bricks.

[0035] The brick is then lifted onto the roller 2 and pushed to slide on the roller 2 to the middle of the cutting table 1 until it reaches the front of the limit plate 43 at the top of the brick end. The electric push rods 48 on both sides of the top of the cutting table 1 are then turned on to make the extrusion plate 49 move against the brick to achieve fixation. At this time, the worker needs to lift the pressure rod 512 so that the pressure rod 512 rotates in the lower pressure groove 518, driving the first connecting rod 512 at one end of the pressure rod 512 to move. When the second threaded rod 522 rotates, the rack 524 threadedly connected thereto moves along the thread on the second threaded rod 522, causing the gear 525 meshing with the rack 524 to rotate, driving the cutter head 527 at the bottom of the lower rotating shaft 526 to rotate, so as to adjust the cutting angle to meet the cutting requirements.
