"Monitor，Why do so many tires need to be repaired and replaced every day？So tired！"This is the most frequently repeated sentence by Gao Xiaohu, a maintenance worker at the auxiliary transportation team of Sunjiacha Longhua Mining Company，The same issue has been discussed more than once at the district team committee meeting，Frequent M88 apprepair and replacement of tires has become a "worry" for the auxiliary transport team，Recently，A technological innovation of the team completely solved this problem。

Ensuring the safe operation of underground vehicles is the primary task of the auxiliary transportation team。Auxiliary transportation lines transport materials via vehicles for a long time，It is inevitable that small objects loaded in the compartment will continue to bump and spill on the road while the vehicle is driving，Similar to U-shaped card、Nail、Screw、E-shaped pin、Iron wire、Gaskets and other metal objects can easily cause damage to vehicle tires，Can be called the "invisible killer" of tires。Minor M88 apprepair and replacement of tires，Affecting vehicle operation，In severe cases, a tire blowout may occur，Causing damage to people and vehicles。According to the tire repair and replacement records of the Auxiliary Transport Team from January to February 2023，It is not difficult to find that the main cause of tire damage is nails、Caused by sharp objects such as screws。

As the saying goes，"The soldiers are coming to stop them，Water will cover the earth。”The key to solving the tire puncture problem is to remove sharp objects on the auxiliary transportation lines。For this，The technical backbone of the auxiliary transportation team combined with the actual situation of auxiliary transportation lines and explosion-proof pickup trucks，Soft connection through chain，Fix the φ20 steel pipe and fix the powerful magnets (φ10cm*10 pieces) side by side on the rear bumper of the explosion-proof pickup truck，It can ensure the swing range of the magnet，It can also ensure that the magnet is not damaged by collision，The height can also be adjusted according to the road conditions。

"After regular iron removal on auxiliary transportation lines，The round trip of iron removal vehicles on the auxiliary transportation line can efficiently recycle metal objects on the road in one go，The workload of tire M88 apprepair and replacement has dropped significantly。After many tests，The magnet M88 loginis 2-3cm away from the ground，Best absorption effect。” Fan Zhipeng, captain of the auxiliary transportation team, commented on the actual use effect of the iron removal truck。

Today，The iron removal vehicle has been operating safely on the auxiliary transportation line for more than two months，It has achieved good results in ensuring the safety of drivers and passengers and reducing the work intensity of vehicle maintenance workers。

“In the past, maintenance workers had to repair and replace several tires almost every shift，Some maintenance workers come down in one shift，Too tired even to lift chopsticks，Now we occasionally repair and replace it，It’s really worry-free。” said Yang Zhanjun, deputy captain of the auxiliary transportation team。

Always，The auxiliary transportation team of Sunjiacha Longhua Mining Company closely integrates safety production work to carry out innovation and efficiency activities，Encourage all members to participate，Use the wisdom of all employees，Motivate employees to actively develop small inventions、Little Creation、Small innovation、Mass activities such as small improvements and technological innovations，Improving site safety、Construction efficiency，While reducing production costs，Continuously create new highlights。(Zhe Xiaofei Ma Linwei)
