Concrete pump is the use of pressure concrete will be transported along the pipeline a continuous machine, which mainly by the boom, pumping, hydraulic, support, electric control of five parts. Has been widely used in engineering construction and other construction operations, much attention and attention. However, during the specific operation, many users do not know or know little about the operating procedures, which not only affects the service life and work efficiency of the pump truck, but also may cause some safety faults. Therefore, it is necessary to understand the relevant safety operation rules The system is particularly important. The law of safety of concrete pump: Article 17 stipulates that the safety operation of concrete pump truck mainly includes the preparation, operation inspection and pumping operation of pump truck. There are 17 main provisions, the specific requirements are as follows: Preparation of pump operation 1, the composition of the concrete pump truck chassis, internal combustion engines, air compressors, pumps, hydraulic devices, etc., the implementation of the general provisions of the car and the concrete pump should be the relevant provisions. 2, pump truck location should be flat and solid, no obstructions around, no overhead high-voltage power lines. Pump truck may not be parked on the slope. 3, pump truck in place, should support the leg and maintain the level and stability of the fuselage. When using fabric rod feeding, the fuselage inclination of not more than 3 °. 4, in place, the pump should open the parking lights to avoid collision. Concrete pump Second, the pumping operation before the check action 1, fuel oil, lubricating oil, hydraulic oil, water tank to add adequate compliance with the tire pressure, lighting and signal light well; 2, the hydraulic system is working properly, the pipeline no leakage; cleaning Pumps and equipment well; 3, mixing bucket without debris, the hopper on the protection of the grid intact and tight cover; 4, conveying pipe connection is firm, well sealed. 5, Fabric pipes and hoses should be used according to the provisions of the factory instructions, may not use more than the specified diameter of the pipe, the hose should be attached to prevent the safety belt buckle. 6, Stretching cloth rod should be in accordance with the order of the factory manual, cloth rod lift back from the bracket can be rotated. It is strictly forbidden to lift or pull objects by cloth rod. 7, when the cloth rod is fully extended state, shall not move the body. Need to move the bodywork operation, the upper section should be folded cloth rod, the speed of movement shall not exceed 10km / h. 8, shall not drag the front end of the fabric hose on the ground; is strictly prohibited to extend the fabric piping and fabric rod. When the wind is at level 6 and above, do not use the cloth rod to deliver concrete. 9, laying of pumping pipe, concrete pump should be in accordance with the provisions of Article II of the implementation. 10, before pumping, when the hydraulic oil temperature is below 15 ℃, should be used to extend the air-time to increase the oil temperature. Third, the pumping operation 1, After the operation, all the concrete pipes and hoppers should be output, and then hoppers, pipes and other washing. When using compressed air flushing pipe, the pipe outlet side of the front 10m is strictly prohibited station. 2, after the operation, shall not flush the fabric rod with compressed air piping, fabric folding rod contraction should be carried out in accordance with the provisions of the order. 3, after operation, all parts of the control switch, adjust the handle, hand wheel, lever, cock, etc. should be reset, the hydraulic system should be unloaded, and should be recovered back legs, the car parked in a safe zone, close the doors and windows. Winter should be exhausted. The above is the safe operation of concrete pump 17 "Golden Rules", I hope for your specific operation to help.
