Scraper Conveyor Chain Tensioner For Coal Mine

The chain fastener of the scraper or the chain fastener of the transfer machine is divided into manual chain fastener and hydraulic chain fastener. By applying certain pre-tightening force to the chain of the scraper, the scraper conveyor can operate safely. When tightening the chain, fix one end of the chain scraper on the side plate of the nose frame or chain chute, and bypass the other end of the chain wheel of the head to make the chain wheel reverse, and then the chain scraper is strained. When the chain tension of the chain scraper is appropriate, the chain scraper will brake to prevent the chain of the chain scraper back loose. After the two chain heads are connected, the chain scraper will remove the brake. The hydraulic chain controller is composed of two parts: the gearbox and the hydraulic control system. It is installed on the connecting cover barrel between the main engine reducer and the motor. When adjusting the hydraulic control valve set during installation, please note: 1. Carefully observe the pressure gauge when adjusting the hydraulic control valve group. As soon as the pressure gauge is out of range, cut off the pressure source quickly to prevent damage to the gauge. 2. The adjustment should be patient and meticulous, and the recommended amount of each adjustment should not exceed 0.5mpa. 3. The hydraulic control valve set should be handled with care to prevent knocking and scratching the anti-rust layer. 4. After adjustment, lock the handle of the pressure reducing valve.

The hydraulic chain tensioner has the following advantages: (1) The braking mode is reasonable and reliable. In the large scraper conveyor, the excessive torque can not be braking through the brake disc, and the hydraulic motor tight chain system internal braking function braking, the way is more reasonable, more reliable. (2) Low fastening speed is conducive to control. The hydraulic motor tightens the chain, the motor speed is 100 RPM, after the reducer, the drive sprocket speed is lower, the chain speed is lower, more conducive to control. (3) Simple operation, more conducive to control. Compared with the brake disc chain tightening device, the scraper conveyor hydraulic motor chain tightening system only needs to pull the operation handle or press the operation button, and the hydraulic system can complete the chain tightening. (4) High safety factor. Hydraulic motor chain fastener has the advantage of hydraulic system, compared with the brake disc chain fastener of mechanical brake, overload unloading and transmission torque is more stable, high safety. Scraper conveyer hydraulic motor tight chain system progress day by day, together with the coal mine fully mechanized working face automation degree more and more high, will become the future coal machine configuration mainstream. Henan Shuanzhi production of various types of hydraulic chain, brake disc chain, about more scraper accessories, you are welcome to telephone consultation.

The scraper produced by Henan Shuangzhi is mostly made of materials of 27SiMn, 40Cr and 40Mn2. After forging, the strength, hardness and toughness of the above three materials are all improved, and the abrasion resistance and bending resistance are also greatly improved. The specific processing technology of scraper is as follows: blanking â?? heating â?? forging blank â?? punching â?? removing burr â?? tempering â?? shot blasting â?? surface treatment â?? quality inspection. Forging process is the key of processing technology. After the blank is heated in the reheating furnace, the blank is made by forging hammer. During the forging process, the oxide skin on the blank surface is knocked off, and the depth and hardness of the hardening layer of the scraper blank are more guaranteed. Henan Shuangzhi supplies the following types of scraper: 101S-01 scraper, 150S0117-1 scraper, 5GL02-2A scraper, 1GL3-1 scraper, 43GL03-1 scraper, 77GL3-1 scraper, 3S001-00/14 scraper, 8GL04-1 scraper, etc. More scraper models can contact us for verification, provide drawings can also provide customized services. Scraper is only a small part of our business, Henan Shuangzhi machinery mainly produces and manufactures all kinds of coal parts forgings, scraper parts, transfer machine parts, hydraulic bracket parts, etc., Henan Shuangzhi all involved. If you need coal parts forgings, you are welcome to contact us. All staff of Henan Shuangzhi will serve you wholeheartedly.

The 7S001-35 hydraulic chain reducer is installed on the connecting casing between the main engine reducer and the motor, and the hydraulic motor drives the main engine reducer to achieve the purpose of tensioning the scraper chain. 7S001-35 hydraulic chain tensioning device is a kind of scraper chain tensioning device powered by hydraulic motor, which is composed of transmission box and hydraulic control system. The hydraulic control system includes control valves, filtration devices and piping, etc. Attention should be paid to the installation of 7S001-35 hydraulic chain fastener: 1. Before each tightening chain, the main engine motor cannot be powered on when the chain reducer meshing with the main engine reducer. 2. The hydraulic motor cannot be used as power transport material, otherwise it may cause premature damage to the hydraulic motor. 3. In the process of tightening chain, the materials on the main machine should be cleaned as far as possible. 4. Pay attention to the observation when tightening the chain, should understand that the scraper chain tension is increasing, remember not to make the chain too tight. The 7S001-35 hydraulic chain fastener belongs to the main engine accessories of Zheng Coal machine. When in use, please pay attention to cut off the power supply of the main engine motor and fix the scraper chain with the chain stopper. More scraper parts consultation attention Henan Shuangzhi
