Concrete mixers need to be aware of which things

Answer:

The concrete mixer driver must be familiar with the performance and operation of the machine, and wear the protective equipment according to the regulation. Article 2: before work should check whether the transmission clutch and brake is flexible and reliable, climbing rope fights with and without broken wires, transmission components such as the mixer of the big gear, pulley guard is in good condition, whether the motor grounding is good, confirmed rear can work. Article 3: the driver is not allowed to leave the job in the operation of the machine, and when the blender is running, it is forbidden to reach into the mixing bowl with an axe, spade or any other object. Article 4: when the hopper arises, no one shall pass or stay in the hopper. If it is necessary to check and repair, the power should be cut off, and the bucket will be held in the back of the link. Article 5: when the feeding operation is strictly prohibited, the operator will put the head into the hopper and the rack to inspect the loading condition. Article 6: if you need to go into the mixing tube for cleaning, you should disconnect the power supply, remove the fuse, and put the lock on the switch box, or be guarded by a special person.
The concrete mixer should be set in a flat position, and the wheel shaft will be placed on the back and back of the square, so that the tyre should be set up so that it will not move during the run. 2, the concrete mixer should be protected by secondary leakage, and after the power connection is put on before work, it must be carefully checked, and it will be used only if it is considered qualified by the empty car test. Commissioning should check when mixing drum speed whether appropriate, under normal circumstances, the proportion of empty car speed car was faster (after loading) 2 ~ 3, such as the difference is more, should adjust pulley and the proportion of the driving wheel. The rotating direction of the mixing cylinder shall be in accordance with the direction of the direction of the arrow, if it is not true, the motor connection shall be corrected. 4, check whether the transmission clutch and brake is flexible and reliable, wire rope is damaged, track pulley are in good condition, surrounded by accessibility and lubrication situation of each part. After turning on the machine, it is often noted that the parts of the concrete mixer are working properly. When stop, check whether the concrete mixer blade is bent and the screw is loose or not. 6, when the completion of concrete mixing or pause is expected to more than 1 h, besides excess stock out of the net, the application of stones and water to pour into shaking inside the cylinder, turn on, put the glue on the cylinder of the mortar all discharged after rinse. No water is allowed in the cylinder in case the cylinder and blade are rusted. It should also clean up the outside of the mixing cylinder to keep the machine clean. 7, after work and stop after work, should pull off power without power, and lock switch box, to assure safety.
Prior to the use of the new machine, the requirements of the manual of the concrete mixer shall be conducted according to the instructions of the concrete mixer, and the test and the necessary trial operation shall be conducted for each system and the parts. Running in the empty car, checking the rotation direction of the mixer or stirring leaves, the operation of each work unit, the brake, the confirmation of normal, the operation. Fixed concrete mixer should be installed on a strong pedestal. When used in the long term, the ground bolts shall be buried; If used in the short term, you can lay the sleeper and stabilize the sleeper. For mobile concrete mixer, it should be installed on flat and hard floor with square or supporting frame, and hold water flat tire. If more than three months should be used, the tire should be removed properly and the shaft end should be cleaned and rusted. For some mixers that need to be excavated, the ground of the pit should be strengthened to prevent the surface water from entering the pit. The bottom end of the material rail frame should be rammed or laid, and the back of the frame shall be supported by wood to prevent the deformation of the track during work. After the concrete mixer has been started, the mixing drum should be made up after normal speed and after loading, it should be added to the water in time. The new material must be removed before it can be removed. Do not start the blender when the load is stopped or full load, except for the reverser.
