All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example (b): referring to fig. 1-4, a load anti-falling device for hoisting machinery, including safety box 1, two notches have been seted up at safety box 1's top, equal slidable mounting has slider 7 in two notches, install a plurality of telescopic links 3 on safety box 1's the bottom inner wall, briquetting 4 is installed jointly at the top of a plurality of telescopic links 3, briquetting 4's both sides are laminated with one side of two slider 7 respectively, install the buffer unit who plays the cushioning effect to briquetting 4 on safety box 1's the bottom inner wall, two sloping frames 5 are installed to briquetting 4's bottom, the L-shaped groove has all been seted up on safety box 1's the both sides inner wall, two L-shaped grooves are linked together with two notches respectively, two L-shaped inslot equal slidable mounting have L shaped plate 6, cylinder 14 is all installed to one side of two L shaped plates 6, two oblique frames 5 are run through respectively to the one end of cylinder 14, the hold-down mechanism who compresses tightly slider 7 is all installed to one side of two L shaped plates 6.

By means of the structure: when the goods of hoist load dropped, briquetting 4 received the pressure downstream of goods, and the buffer unit cushions the buffer power that the goods dropped downwards, and meanwhile, two sliders 7 constantly increase the pressure of briquetting 4 both sides under hold-down mechanism's effect, and vertical friction constantly increases promptly to play the effect of further buffering, and then avoid the goods to fall impaired after.

As shown in fig. 2 to 4, the buffer unit includes a plurality of buffer springs 2, the plurality of buffer springs 2 are all installed on the inner wall of the bottom of the safety box 1, and the top ends of the plurality of buffer springs 2 are all connected with the bottom of the pressure block 4. Through the setting of a plurality of buffer spring 2 for the impact force that a plurality of buffer spring 2 compression can cushion the goods and drop downwards, and then play the cushioning effect of device.

As shown in fig. 2 and 4, the pressing mechanism includes a supporting seat 8 and a sliding rod 9, the supporting seat 8 is installed on one side of the L-shaped plate 6, one end of the supporting seat 8 is provided with a sliding groove, the sliding rod 9 is slidably installed in the sliding groove, one end of the sliding rod 9 is connected with the sliding block 7, and an extruding element for extruding the sliding rod 9 is installed on the inner wall of one end of the sliding groove. Through the setting of supporting seat 8 and slide bar 9 for two sliders 7 extrude the both sides of briquetting 4, make the frictional force increase between briquetting 4 and two sliders 7, play the effect of further buffering.

As shown in fig. 2 and 4, the pressing member includes a pressing spring 10, one end of the pressing spring 10 is installed on the inner wall of one end of the slide groove, and the other end of the pressing spring 10 is connected with one end of the slide rod 9. Through the setting of pressure spring 10, two L shaped plates 6 remove in opposite directions for two pressure spring 10 further compress, and then lead to two sliders 7 to the continuous increase of pressure of briquetting 4, hold-down mechanism's cushioning effect reinforcing.

As shown in fig. 3 and 4, a ferrule 11 is mounted at one end of the cylinder 14. This has the advantage of avoiding the cylinder 14 from falling out of the bezel 5 during the movement of the cylinder 14 within the bezel 5, which could result in the device not being able to continue to operate.

As shown in fig. 1-3, an airbag 12 is mounted on top of the mass 4. The benefit that sets up like this is for partly impact force is offset when the goods falls on the device, plays certain cushioning effect, avoids appearing the direct roof that falls at briquetting 4 of goods, and briquetting 4 is impaired because of the impact of goods.

As shown in fig. 1-3, the bottom of the safety box 1 is fitted with a cushion pad 13. The advantage of this arrangement is that when goods fall on the device, the whole device will be subjected to a certain impact force, and the cushion pad 13 will absorb this impact force, avoiding this impact force to act directly on the ground, resulting in ground fragmentation.

This practical theory of operation:

when the goods of hoist load dropped, the goods fell on air bag 12, air bag 12 compresses, simultaneously under the cooperation of telescopic link 3, briquetting 4 received the pressure downstream of goods, make buffer spring 2 compress, and then can cushion the downward impact force that drops of goods, meanwhile, two oblique frame 5 downstream, oblique frame 5 downstream can extrude cylinder 14, make two cylinders 14 remove in opposite directions, and then drive two L shaped plates 6 and be close to two sliders 7 respectively, further compress two pressure spring 10, make the pressure increase of two sliders 7 to briquetting 4 both sides, perpendicular frictional force constantly increases promptly, play the effect of further buffering, thereby it can not impaired to protect after the goods drops.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the utility model.
