Hand gourd it used in structural design and performance

Hand moving hoist used in structural design and manual hoist, it has five characteristics: (1) the use of safe, convenient maintenance; (2) high mechanical efficiency, hand pull small; (3) the lighter weight, easy to carry; (4) beautiful appearance, small size; (5) durability. Daxing coal mine the chain hoist are used in factory maintenance, commonly used the HS series chain hoist adopts symmetrical arrangement of secondary spur gear hoist equipment mechanism, the maintenance, should be no load and overload test, confirm the work can be used in production. Often caused by a lack of detection means, chain blocks with the hidden trouble in production use, repair rate. Therefore, it is necessary to develop a tester, for the maintenance manual hoist loading experiment. 1 process manual hoist tester developed ever implement two kinds of schemes, finally, selected as shown in figure 1 new manual hoist tester, tension meter available directly shows that have been rated lifting weight of the chain hoist. The working principle of tension meter is spring absorption manual hoist external pulling force. After the spring load can produce corresponding deformation, unloading and then can recover

Manual stop block is different from automatic clutch, brake and accelerator

Chain by pulling to move the chain, hand wheel rotation, the friction slice ratchet wheel, brake manual hoist into one common rotation, short and long axis rotation piece of gear, the tooth axis and the spline gear. In this way, the device on the spline gear of lifting chain wheel drives the lifting chain, so as to smoothly promote the weight. Unilateral brake friction ratchet type, can self braking under load, ratchet in spring and ratchet gearing, under the action of the brake safety work. Gourd after cleaning maintenance, should carry on the no-load test, the work is normal, reliable braking, can consign is used. Manual stop block is different from automatic clutch, brake and accelerator to cooperate can stand a good car, than manual stop block driving automatic-shift trival, but also has its own advantages, open often will become adept. Start technique. Different from automatic buffer, buffer started hoist equipment, the left foot on the clutch, hang a, above the vanity with right foot on the accelerator, slow up the clutch brake light step on the gas at the same time, at the same time lets go clutch after left foot on the accelerator slowly up completely, vehicle start smoothly. But when you meet the high starting clutch to be carried to the right, his left foot or the vehicle is in a state of "linkage", then even if the hand brake, loose braking, the vehicle will not slide. Then follow the step on the gas, and slowly lift the clutch, hand brake, the car started.
