[0029] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] This utility model embodiment provides a vertical fall arrestor for hoisting, including a mounting base 1. The mounting base 1 is equipped with a retracting mechanism for hoisting purposes. The retracting mechanism includes a fall arrestor to prevent falls during hoisting, improving safety. The fall arrestor also includes a return mechanism to deactivate its fall arrestor function and return it to its original position for convenient subsequent use. The retracting mechanism includes a first vertical plate 8, fixedly mounted on the mounting base 1. The first vertical plate 8 supports a receiving roller 6, which is rotatably connected to it. The receiving roller 6 is used to retract and extend a hoisting rope 7, which is wound around it for hoisting objects. The fall arrestor includes a shaft 23, fixedly mounted on the mounting base 1. The shaft 23 at one end of the take-up roller 6 facilitates the rotation of the receiving plate 24 when the take-up roller 6 rotates. One end of the shaft 23 passes through the first vertical plate 8 and is fixedly installed with the receiving plate 24. The receiving plate 24 is used to support the installation of the slide rod 25. The slide rod 25 is fixedly installed on the receiving plate 24. The slide rod 25 is used to support the sliding of the slider 210. The slider 210 is slidably mounted on the slide rod 25. The slider 210 is used to support the installation of the insert 27. The insert 27 is fixedly installed on one side of the slider 210. The insert 27 is used to be inserted into the slot 26, thereby achieving the purpose of limiting and fixing the receiving plate 24. The receiving ring 21 is fixedly installed on the side of the first vertical plate 8. The receiving ring 21 is used to support the opening of the slot 26. The inner wall of the receiving ring 21 has a slot 26. The slot 26 is used to support the insertion of the insert 27.

[0031] The repositioning mechanism includes a turntable 31, which is rotatably connected to one end of the receiving ring 21. The turntable 31 is designed to receive the opening of the drive groove 32. The drive groove 32 is provided on the turntable 31 and is designed to drive the drive rod 34 to move. The drive rod 34 is fixedly installed on the slider 210 and slides on the inner wall of the drive groove 32.

[0032] A second vertical plate 4 is fixedly installed on the mounting base 1. The second vertical plate 4 is set vertically, and the take-up roller 6 is rotatably connected to the side of the second vertical plate 4. The second vertical plate 4 is set to receive the installation of the take-up roller 6.

[0033] A motor 5 is fixedly installed on the side of the second vertical plate 4. The motor 5 is horizontally set and has forward and reverse rotation functions. The motor 5 is set to drive the take-up roller 6 to rotate. The shaft end of the motor 5 passes through the second vertical plate 4 and is fixedly connected to one end of the take-up roller 6.

[0034] The shaft 23 is horizontally positioned and is cylindrical in shape. The receiving plate 24 is circular in shape and is vertically positioned. The receiving plate 24 is used to support the installation of the slide rod 25.

[0035] The slide bar 25 has a groove 28, which is a strip-shaped groove. The groove 28 is designed to support the rolling of the roller 22.

[0036] The surface of the slider 210 is provided with a through hole 211. The through hole 211 is square in shape. The through hole 211 is provided to support the installation of the roller 22 and also facilitates the insertion of the slide rod 25. The inner wall of the through hole 211 is provided with the roller 22. The roller 22 slides on the inner wall of the slide groove 28. By providing the roller 22 and the slide groove 28, the slider 210 slides more smoothly on the slide rod 25.

[0037] The receiving ring 21 is circular in shape and is vertically arranged. The inner wall of the slot 26 is provided with a magnetic strip. By providing a slot 26 with a magnetic strip, it is easy to attract the insert 27 and prevent the insert 27 from falling out of the slot 26.

[0038] A magnetic block 29 is fixedly installed on the inner wall of the slide bar 25. The magnetic block 29 is in the shape of a circular plate and is set vertically. The magnetic block 29 is set to attract and fix the slider 210.

[0039] Both the slider 210 and the insert 27 are made of iron. The slider 210 is a square block and is designed to support the installation of the insert 27.

[0040] The drive rod 34 is cylindrical, and a handle 33 is fixedly installed on the side of the turntable 31. The handle 33 is horizontally positioned and is used to rotate the turntable 31.

[0041] When hoisting items, the motor 5 is started, which drives the take-up roller 6 to rotate. As the take-up roller 6 rotates, the hoisting rope 7 is released, and the items are hoisted through the hoisting rope 7. If the motor 5 is damaged, the goods will fall rapidly. During the fall, the hoisting rope 7 is subjected to the weight of the goods, which will drive the take-up roller 6 to rotate faster. When the take-up roller 6 rotates faster, it will drive the receiving plate 24 to rotate faster through the shaft 23. When the receiving plate 24 rotates faster, the surrounding sliders 210 will detach from the magnetic block 29 due to the centrifugal force and slide along the surface of the slide bar 25 until the insert 27 on the surface of the slider 210 is inserted into the slot 26. The slot 26 is equipped with a magnetic strip to attract and fix the insert 27. Through the above settings, the receiving plate 24 can be limited, making it easier to fix the take-up roller 6 through the shaft 23 and prevent the goods from falling.

[0042] Furthermore, since the turntable 31 is rotatably connected to the receiving ring 21, the turntable 31 and the drive rod 34 will not interfere with the movement of the slider 210. At the same time, the setting of the roller 22 and the slide groove 28 makes the slider 210 slide more smoothly.

[0043] When it is necessary to return the slider 210 to its original position, simply turn the handle 33. The handle 33 drives the turntable 31 to rotate. When the turntable 31 rotates, it will drive the four sliders 210 to move together through the drive groove 32 and drive rod 34 until the sliders 210 are attracted to the magnetic block 29. At this time, the fixing of the receiving plate 24 and the winding roller 6 can be released, making it easier for the winding roller 6 to lift items.

[0044] The above-described embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
