Description

Technical Field

[0001] The utility model relates to the technical field of cutting machine blade installation, in particular to a double-blade installation structure of a concrete core cutting machine. Background Art

[0002] The strength test of concrete usually adopts the core sampling method. A core pulling machine is used to drill holes in the concrete component to take samples. The drill bit moves down to drill out a part of the cylindrical concrete block, which is the concrete core sample. Before the compressive strength test of the concrete core sample, the end face cutting, end face grinding, end face repair and other processes are required to be carried out in advance to enhance the accuracy of the compressive strength test of the concrete core sample.

[0003] A core sample double-end face cutting machine mentioned in the existing Chinese public patent (authorization announcement number: CN220242014U). It includes a machine body, a movable frame is arranged on the upper surface of the machine body, a movable seat is installed on the inner side of one end of the movable frame, a cutting motor is installed on the top of the movable seat, a first transmission unit is connected to the shaft end of the cutting motor, and a cutting shaft is connected to the side of the first transmission unit away from the cutting motor. This machine can achieve the double-end face cutting function, which not only speeds up the working efficiency of concrete core sample cutting, but also makes both ends of the concrete core sample receive the cutting force of two blades at the same time, which can effectively avoid the situation that a single blade cutting squeezes one end of the concrete core sample and causes the concrete core sample end face cutting to be skewed; by setting a fixing mechanism, the concrete core sample can be stably clamped, and the friction between the clamping groove and the side wall of the concrete core sample can be increased by using the clamping edge, which effectively limits the rotation of the concrete core sample in the clamping groove.

[0004] In the process of cutting the concrete core, the existing concrete core cutting machine needs to place the concrete core on the device, then start the motor to drive the double blades to rotate, and then make them move toward the concrete core, and the two blades cut the concrete at the same time. However, when the existing device uses the double blades to cut the concrete core, the distance between the blades is fixed and cannot be adjusted according to different needs, which reduces the versatility of the device during use and makes the double blade cutting process more inconvenient.
