安全滑觸線的使用為車間帶來了安全，但也有缺點，橋式起重機在使用中易斷電，有時在輸電導管內(nèi)產(chǎn)生火花，嚴重時滑觸線某放炮"，造成集電器更換過于頻繁，影響生產(chǎn)。
The use of safety sliding contact line as the workshop brought security, but there are also disadvantages, easy off bridge crane in use, sometimes sparks in the transmission conduit, serious when sliding contact line of a shooting ", causing the collector to replace the too frequent, affecting production.
  為此，進行了如下改進：
Therefore, for the following improvement:
  （1）加深。加固集電器中的彈簧座，保證電刷的恢復彈簧在工作中不易"串位"；
(1) deepen. Strengthening the spring seat set in electric appliance, ensure that the brush recovery spring in the work is not easy "on";
  （2）增大集電器電刷倒角，并打磨光滑；
(2) increase the collector brush chamfered, and polished;
  （3）兩段安全滑觸線連接處連接塊要有倒角，保證集電器平滑過渡。同時，為保證安全滑觸線的正常使用，行車工的規(guī)范操作、維修工的定期保養(yǎng)、定期檢查也*。
(3) the two security sliding touch line connected block to have chamfer, ensure a smooth transition in electrical appliance. At the same time, in order to ensure the safety of the normal use of the sliding contact line, operation and maintenance workers driving workers regulate the periodic maintenance, regular inspection is necessary.
  （4）增加集電器兩相對電刷間彈簧強度、彈性，保證彈簧恢復自如；
(4) increase the collector two relative brush spring strength, elasticity, ensure the spring recovery free;
