When the device is used, the electric moving wheel 903 is started to drive the support rod 1 to slide in the moving slide 901, the fixed plate 2 is positioned right above a heavy object, the hook 7 is at an initial position, the pull rope 5 is wound on the outer surface of the rotating rod 4 and is positioned at the highest point together with the clamping mechanism 8, the clamping block 801 is abutted against the hook 7, most of the clamping block 801 is positioned above the fixed plate 2, the limiting groove 6 is positioned at a lower middle position of the clamping block 801 as a supporting point, due to the action of a lever principle, the pull rope 5 and the clamping block 801 cannot shake in the moving process, the pull rope can be effectively fixed in the limiting groove 6, the heavy object or personnel cannot be damaged, the operation speed can be increased in the moving process, the loading and unloading efficiency can be increased, after the lifting position is reached, the motor 10 is started, the motor 10 rotates to drive the rotating rod 4 to rotate, the pull rope 5 is orderly put down in the rotating process, stay cord 5 passes first unwrapping wire hole 802 and puts down, it rotates to drive first bevel gear 11 when dwang 4 rotates simultaneously, first bevel gear 11 drives second bevel gear 12 and rotates, second bevel gear 12 drives the bevel gear board 803 and slides down, grip block 801 of bevel gear board 803 one end descends along with the decline synchronization of stay cord 5, constantly keep its clamping state, consequently, grip block 801 still keeps its effectual clamping state at the in-process that descends stay cord 5, avoid it to take place to rock, thereby improve handling efficiency.

When the pull rope 5 drives the hook 7 to descend to a proper height, the hook 7 is hung with a heavy object, the hanging quality is checked manually for multiple times, the good hanging is ensured, after the hanging is finished, the motor 10 is reversely started, so that the rotating rod 4 is driven to reversely rotate, the pull rope 5 is wound in the rotating process of the rotating rod 4, meanwhile, the first bevel gear 11 can be driven to reversely rotate by the reverse rotation of the rotating rod 4, the first bevel gear 11 drives the second bevel gear 12 to reversely rotate, the second bevel gear 12 drives the bevel gear plate 803 to ascend, so that the clamping block 801 is driven by the bevel gear 803 to ascend, similarly to the descending process, the clamping block 801 and the pull rope 5 synchronously ascend, the ascending height and the frequency are consistent, the clamping force can be ensured to be constantly exerted on the pull rope 5 by the clamping block 801, the swinging of the pull rope in the ascending process is avoided, and finally, when the clamping block 801 slides in the limiting groove 6 and the fixing plate 2 is ensured to be positioned at the lower axial position thereof, the motor 10 stops working, in the rotating process of the rotating rod 4, the heavy object is mainly lifted by the upward pulling action of the pulling rope 5, the maximum lifting weight of most lifting devices is limited because the balance is realized only by the pulling force of the pulling rope 5 after the heavy object is lifted and stabilized, the action point is basically the central point of the fixed plate 2, the stress is too concentrated, and the shaking in the lifting process is easier to increase the stress of the central position of the fixed plate 2 to cause the breakage and collapse of the lifting devices, the device can effectively avoid the problem, although the heavy object is lifted by the pulling rope 5 in the lifting process, the original single-point stress is changed into the existing multi-point stress in the position of the rotating rod 4, the rotating support pulling force is applied to the pulling rope 5 when the rotating rod 4 is lifted, and meanwhile, the first bevel gears 11 and the second bevel gears 12 of the rotating rod 4 at the two end parts of the clamping block 801 are meshed for limiting, second bevel gear 12 is spacing with bevel gear board 803, therefore dwang 4 is promoting the main stress point of in-process and is stay cord 5 and bevel gear meshing position, and the dispersion atress of multiposition can effectual promotion dwang 4's loading ability, and the increase promotes weight, guarantees the device security.

After the hoisting device finishes lifting the heavy object, the electric moving wheel 903 is started to drive the device to slide in the moving slideway 901, at the moment, due to the clamping action of the clamping block 801 on the pull rope 5, the hook 7 and the heavy object at the bottom of the pull rope 5 cannot shake, meanwhile, due to the lifting height of the clamping plate 801, the fixed plate 2 is positioned at the lower position of the central shaft of the clamping block 801, the position of the limiting groove 6 is a supporting point, as can be known from the moment relation, the product of the force arm and the force at the two ends of the supporting point is equal, the force arm of the clamping block 801 at the top of the fixed plate 2 is long, the heavy object amount is small, the force arm of the clamping block 801 at the bottom of the fixed plate 2 is short, the heavy object amount is large, therefore, through the lever principle, the two ends are basically in a relatively stable state, the hook 7 and the heavy object at the bottom of the pull rope 5 cannot shake, the acting force of the clamping plate 801 on the fixed plate 2 is minimized, and the inertial buffer damage cannot be caused to the fixed plate 2, the safety of the device is guaranteed, when the electric moving wheel 903 drives the hoisting device to reach a required position, the working process is repeated, and the heavy object is moved downwards and the original position is restored again. The device not only can carry out the centre gripping to stay cord 5 fixed, thereby avoids it to take place the slope at the hoist and mount in-process and rock and lead to the fact the collision damage to property or personnel, increases its hoist and mount efficiency and operability, improves the security of device, can also effectually disperse the atress to the heavy object, increases top dwang 4's stress point, promotes hoist and mount weight, the stability of improvement device.
