自动搅拌车因机动性强，占用场地少，操作简便，运行可靠等特点，广泛应用于混凝土小型构件、围挡、涵洞等野外施工中。同时，由于其用电量不大、临时性显著，操作技能要求低等因素，而往往成为安全生产管理的薄弱点，电源接入、配电线路、配电箱、开关箱以及机械防护等常常存在诸多安全隐患。
The automatic mixer is widely used in the field construction of small concrete components, fences, culverts, etc. due to its strong mobility, less occupation of site, simple operation and reliable operation. At the same time, because of its small power consumption, significant temporary, low operating skill requirements and other factors, it often becomes the weak point of safety production management. There are many potential safety hazards in power supply access, distribution lines, distribution boxes, switch boxes and mechanical protection.
1、接入电源未按规定设置配电箱，无配电箱，或配电箱无门、无锁、无防雨措施，接线不规范。
1. The power supply is connected without distribution box as required, or the distribution box has no door, lock, rainproof measures, and the wiring is not standardized.
2、电源接线未按规定架空或填埋（违规直接沿地面敷设）。
2. The power wiring is not overhead or buried as required (it is directly laid along the ground in violation of regulations).
3、违规使用护套线或代替橡胶电缆（尤其是动力缆线）。
3. Use sheathed cable or replace rubber cable (especially power cable) in violation of regulations.
4、缆线护套严重破损。
4. The cable sheath is seriously damaged.
5、无开关箱、无漏电保护器或开关箱无漏电保护器。
5. There is no switch box, leakage protector or leakage protector in the switch box.
此外这些事项也要做好，如：
In addition, these matters should also be done well, such as:
搅拌车在空载运行过程中，搅伴筒不得停转以免颠簸时造成滚道和托轮局部磕碰，导致托轮和滚道的异常损坏。
In the process of no-load operation of the mixer, the mixing and tracing cylinder shall not stop to avoid local collision between the roller and the supporting wheel caused by turbulence, resulting in abnormal damage to the supporting wheel and the roller.
水箱的水量要经常加满，以备急用。水箱加水前，打开放气阀把箱内空气放掉；冲洗时打开气阀，冲洗完毕或者停用时应将水罐内气体放掉。冬季停放时，水箱和供水系统里不得有剩余水，防止冻裂。
The water tank shall be filled frequently for emergency use. Before adding water to the water tank, open the vent valve to drain the air in the tank; Open the gas valve when flushing, and drain the gas in the water tank after flushing or when it is stopped. When parking in winter, there shall be no residual water in the water tank and water supply system to prevent frost cracking.
满载混凝土正转，如要反转，须操纵手柄使正转停稳后，再操纵手柄反转。严禁正转过程中操纵手柄使其反转。
The full load concrete rotates forward. If it needs to reverse, the handle must be operated to make the forward rotation stop stably, and then the handle can reverse. It is forbidden to reverse the joystick during forward rotation.
The above is the answer to the questions that must be paid attention to about the potential safety hazards of the automatic mixer. If you have any questions or needs, please come to our website http://www.jfhntjbj.com Ask about it!
