Firstly, an operator wears a safety helmet on a model, then adjusts a detection device to a part needing detection, pulls a handle to move rightwards, the handle moves rightwards to drive a clamping rod to move rightwards, a first spring is stretched, the clamping rod moves rightwards to be separated from a gear, the operator can shake a first rocker to rotate forwards, the first rocker drives a first rotary disc to rotate forwards, the first rotary disc drives the gear to rotate forwards, the gear rotates forwards to drive a tooth block to move upwards, the tooth block moves upwards to drive a vertical plate to move upwards, the vertical plate moves upwards to drive an n-shaped plate to move upwards, the n-shaped plate moves upwards to drive a pull wire to move upwards through a wire guide wheel, further drives the detection device to move upwards, when the detection device moves upwards to a proper height, the first rocker stops shaking, the handle is released, the clamping rod moves leftwards to be engaged with the gear to clamp the clamping rod, and the detection device stops moving upwards due to the action of the first spring, the operating personnel can loosen the acting as go-between, because of the influence of gravity, detection device moves down and drives the downstream of acting as go-between, and the acting as go-between drives the wire wheel reversal, and detection device moves down and pounces and carry out the quality to it on the safety helmet and detect. After the safety helmet is detected, the detection device is adjusted to different detection parts, the right end of the pull wire is pulled to move downwards, and then the left end is pulled to move upwards to drive the detection device to move upwards to return to the original position. After the safety helmet is completely detected, the handle is pulled to move rightwards again to enable the clamping rod not to be meshed with the gear, the first rocker is shaken to rotate reversely, the gear rotates reversely to drive the vertical plate to move downwards through the tooth block, the detection device is driven to move downwards to recover to the original position, the first rocker is stopped to be shaken, the handle is loosened to enable the clamping rod to clamp the gear, whether the safety helmet breaks or not can be checked, if the safety helmet breaks, the quality is not over, and if the safety helmet breaks, the quality is over.
Firstly, an operator twists a fastening bolt to move outwards without contacting with a circular block, then rotates the circular block to enable one of the striking blocks to rotate right below, then twists the fastening bolt to move inwards to contact with the circular block to fix the circular block, and further when the operator loosens a pull wire, due to the influence of gravity, the n-shaped frame moves downwards to drive the circular block to move downwards, the circular block moves downwards to drive the striking block to move downwards, and the striking block moves downwards to strike on the safety helmet to detect the striking block. After the safety helmet is detected, an operator twists the fastening bolt to move outwards without contacting with the round block, rotates the round block to enable the other type of knocking block to rotate to the position right below the round block, pulls the right end of the stay wire to move downwards, then pulls the stay wire to drive the n-type frame to move upwards, then drives the knocking block to move upwards to restore to the original position, the operator can loosen the stay wire again, then the knocking block moves downwards to pound on the safety helmet, and the operation is repeated, so that the safety helmet can be detected comprehensively.
When the detection device moves upwards to a proper height, an operator can pull the clamping block to move downwards, the second spring is compressed, the clamping block moves downwards to be separated from the clamping groove, the striking block moves downwards to drive the pull wire to move downwards due to the influence of gravity, the pull wire drives the reel to rotate forwards, the reel rotates forwards to drive the third rotating shaft to rotate forwards, the third rotating shaft rotates forwards to drive the second rotating disc to rotate forwards, when the striking block moves downwards to hit the safety helmet to detect the quality of the safety helmet, the operator can loosen the clamping block, the clamping block moves upwards to be clamped into the clamping groove to fix the second rotating disc due to the action of the second spring, when the operator rotates the other striking block downwards, the second rocker can be shaken to rotate reversely, the second rocker rotates reversely to drive the second rotating disc to rotate reversely, the clamping block slides on the clamping groove in a reverse rotating manner, and simultaneously, the second rotating disc rotates reversely to drive the third rotating shaft to rotate reversely, the third rotating shaft reversely rotates to drive the reel to reversely rotate, the reel reversely rotates to wind the pull wire, the pull wire drives the knocking block to move upwards to return to the original position, and the second rocker is stopped to shake. Therefore, the pull wire is more convenient for operators to retract the pull wire so that the beating block moves upwards and returns to the original position.
When the pull wire moves to drive the wire guide wheel to rotate, the pressing wheel is always in contact with the pull wire due to the action of the torsion spring, the pressing wheel is matched with the wire guide wheel to guide the pull wire, and the pressing wheel can prevent the pull wire from being separated from the wire guide wheel to influence the movement of the knocking block.
When the stay wire moves to drive the wire guide wheel to rotate, the wire guide wheel rotates to drive the first rotating shaft to rotate, the first rotating shaft rotates to drive the first belt pulley to rotate, the first belt pulley rotates to drive the second belt pulley to rotate through the flat belt, the second belt pulley rotates to drive the rotating blades to rotate, the rotating blades rotate to exhaust air, and the air is blown to the wire guide wheel to dissipate heat. Thus, the wire guide wheel can be prevented from being broken due to too high temperature.
The invention has the following advantages: according to the invention, the knocking block can be moved upwards to a proper height by shaking the first rocker, and then the pulling wire is released, so that the knocking block can be moved downwards to be hammered on the safety helmet to detect the quality of the safety helmet, the safety helmet can be accurately detected, people do not need to take an object to move to a high place to throw the object down, time and labor are saved, the pulling wire can be more conveniently collected by an operator through the auxiliary device, and the pulling wire can be prevented from being separated from the wire guide wheel to influence the detection of the knocking block on the safety helmet through the action of the pressing wheel.
