Detailed Description

The present invention will be further described with reference to the following detailed description and the accompanying drawings, but the present invention is not limited to the specific examples.

Example 1

As shown in fig. 1 and 2, the reel 1 for winding and unwinding the safety fence 6 comprises a handheld handle 3, a rotating shaft 2, a hub 4 and a rotating module 5, wherein the handheld handle 3 is arranged at two ends of the rotating shaft 2; the hubs 4 are respectively connected to the inner sides of two ends of the hand-held handle 3 and are coaxial with the rotating shaft 2; the rotating module 5 is arranged on the outer side of one end of the handheld handle 3 and is coaxial with the rotating shaft 2; the rotation module 5 comprises a rotation stop knob 7. Before the safety fence 6 is arranged, the whole reel 1 can be driven to move to a position to be arranged through the rotation of the hub 4, and can also be carried and taken up to the position to be arranged through the hand-held handle 3. When arranging security fence 6, the one end of security fence 6 in the reel that will receive and release security fence is fixed on the railing pole that will arrange, then the staff holds handheld handle, will only change knob 7 and open, and manual going corotation rotates module 5, rotates module 5 and drives axis of rotation 2 corotation afterwards, and security fence 6 spreads out fast in the reel, until security fence 6 stretches out completely, unties the end of binding security fence 6 in axis of rotation 2 and can accomplish spreading of security fence 6 and arrange. After the spread out and arrange work, only need to fix the one end of security fence 6 on axis of rotation 2, manual going to reverse rotation module 5 rotates module 5 simultaneously and will drive axis of rotation 2 reversal, and security fence 6 will roll fast and enter, will only rotate knob 7 after that and close, and reel 1 will unable rotation, accomplishes security fence 6's rolling. After the safety fence 6 is rolled up, the hub 4 can be rotated to drive the reel 1 to move to a position to be placed, and the hand-held handle 3 can also be used for carrying the safety fence to the position to be placed. If the part with the rotary winding is touched, the safety fence 6 can be rotated to the normal position only by rotating the hand-held handle 3 by hands, and the problem of winding of the safety fence 6 in the daily use process is solved.

Preferably, as shown in fig. 1 and 2, a fixing member 8 is further provided between the hub 4 and the two ends of the handle 3, and the fixing member 8 is used for fixing the reel 1. The fixing piece 8 arranged between the hub 4 and the handle 3 can ensure that the reel 1 can be stably and horizontally placed on the ground when the reel does not need to be rolled and moved, can not move, and can be fixedly placed at a position where the reel is required to be placed.

More preferably, as shown in fig. 2, the fixing member 8 is in the shape of a circular arc. The fixing part 8 is in the shape of an arc, and the design of not a complete circle is adopted, so that the weight of the whole device can be reduced, and the rotation of the hub 4 can be facilitated.

More preferably, as shown in fig. 2, the fixing member 8 has a hollow structure. The fixing part 8 is of a hollow structure, so that the weight of the whole reel 1 can be greatly reduced, and the arrangement of the safety fence 6 needs frequent replacement, so that the carrying weight needs to be moved more lightly.

More preferably, as shown in fig. 3, the hub 4 is of an open structure. The hub 4 is of a hollow-out construction, which greatly reduces the weight of the entire reel 1, since the arrangement of the safety rail 6 requires frequent replacement of the site and therefore requires lighter movement and reduced carrying weight.

More preferably, as shown in fig. 1, the hub 4 has a diameter larger than the diameter of the rolled-up safety rail 6. The design that the diameter of wheel hub 4 is greater than the diameter after security fence 6 is rolled up can let security fence parcel in wheel hub 4's protection better, avoids receiving the damage at the removal or receive and release the in-process.

More preferably, the reel 1 is an aluminum alloy or a carbon fiber material. The reel 1 is made of aluminum alloy or carbon fiber materials, so that the weight of the whole reel 1 can be greatly reduced, and the reel can be moved more lightly and the carried weight can be reduced. Any other lightweight material that meets the strength and use requirements may also be used for the power reels 1, and is not limited to aluminum alloy or carbon fiber materials.

Example 2

The present embodiment is different from embodiment 1 in that: the rotation module 5 comprises a manual crank (not shown). Rotation module 5 includes manual rocking handle, and manual rocking handle can let operating personnel conveniently grip, better takes the axis of rotation 2 to more rapidly with the rolling of security fence 6 and spread.

The other structure is the same as embodiment 1.
