A cleaning protection device for cement bending test machine

Abstract

The invention relates to the technical field of cement test equipment, in particular to a cleaning and protecting device for a cement anti-fracture testing machine. The cleaning and protecting devicecomprises a protective cover, an opening and a closing plate are arranged on one side of the protective cover, a first elastic element is arranged at the position of the opening, a support is fixed tothe base, a driven roller and a traction rope are arranged on the support, a spiral groove is formed in the side wall of the driven roller, a driving roller is fixed to the end of a main screw rod, and the same belt is tightly wound around the driving roller and the driven roller. A main motor is started to enable the main screw rod to rotate, the main screw rod drives a moving weight to move andcause the driving roller to rotate, the driven roller rotates and causes the traction rope to be gradually embedded into the spiral groove, the pulling rope pulls the closing plate to rotate and closethe opening, and waste chips generated by a workpiece are blocked; and then the main screw rod and the driving roller rotate to fall, the belt loosens, and the first elastic element drives the closing plate to rotate, so that the opening is exposed. The cleaning and protecting device reduces the occurrence of potential safety hazards and facilitates the cleaning and collection of the waste chips.

Description

technical field [0001] The invention relates to the technical field of cement testing equipment, in particular to a cleaning protection device for a cement bending tester. Background technique [0002] The flexural testing machine is mainly used for the flexural strength test of concrete, refractory materials, bricks and other test pieces and the compressive strength test of cement, mortar and refractory materials, bricks and other building materials. [0003] Through retrieval, Chinese patent announcement number CN206192788U discloses a kind of anti-bending testing machine, comprises main lever, secondary lever, base, column, beam, anti-bending fixture, and described base is provided with the first installation station that is used for installing anti-bending fixture , the second installation station; a chute is provided between the first installation station and the second installation station, a sliding seat is slidably connected in the chute, and the sliding seat is prov...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned existing technical solutions have the following defects: after the cement is broken, the cement waste will splash. If the waste splashes on the human body, there will be a certain safety hazard. If a layer of protection is installed outside the testing machine Although the cover effectively blocks the splashing of waste debris, the protective cover needs to be disassembled when the waste debris needs to be cleaned, which is inconvenient to operate, so it needs to be improved
