Detailed Implementation

[0016] Example 1: Please refer to Figure 1-5 As shown, the present application provides a technical solution: a fall prevention device for a bridge crane track beam in a factory, including a crossbar 11 set on the track beam 10, at least two fixed supports 12 set on the crossbar 11, a steel wire rope 13 set between the two fixed supports 12, a locking rope 14 set below the steel wire rope 13, a safety rope 15 set below the locking rope 14, and a storage device 2 set between the locking rope 14 and the safety rope 15 for adjusting the length of the safety rope 15.

[0017] In a preferred embodiment, the storage device 2 includes a storage tube 21 and a locking part. A fixed shaft 23 is provided at the center of the storage tube 21, which extends out of the storage tube 21 and is used to wind the safety rope 15. A first through hole 211 is provided on the side wall of the storage tube 21, through which the safety rope 15 passes. The locking part includes a locking rod 22 that is fitted on the fixed shaft 23 on the outside of the storage tube 21 and moves axially along the fixed shaft 23, and a locking tooth 28 that is provided on one side of the storage tube 21 and cooperates with the locking rod 22.

[0018] With the above structure, when maintenance personnel need to climb to a height, the safety rope 15 can be attached to their body, thus providing protection. When it is necessary to lengthen the safety rope 15, the storage cylinder 21 can be rotated, allowing the safety rope 15 to be pulled out to a specific length as needed.

[0019] The specific operation is as follows: First, hold the locking lever 22, then rotate the fastening ring 25 in the opposite direction. Under the action of the spring 24, the storage cylinder 21 and the locking lever 22 gradually disengage from the lock. At this time, the storage cylinder 21 can be rotated to adjust the length of the safety rope 15. After the adjustment is completed, rotate the fastening ring 25 in the forward direction. The locking lever 22 gradually moves closer to the storage cylinder 21 until the locking lever 22 is engaged in the locking tooth 28 on one side of the storage cylinder 21. At this time, the storage cylinder 21 can no longer rotate, thus locking the length of the safety rope 15. By adjusting the length of the safety rope 15 in this way, it is convenient for maintenance personnel to carry out maintenance work.

[0020] In a preferred embodiment, a keyway 231 is provided on the fixed shaft 23, and a matching guide key is provided on the latch 22.

[0021] With the above structure, when locking, the fixed shaft 23 can only slide in a straight line along the keyway 231, which drives the locking teeth 28 on the storage tube 21 to approach the locking rod 22 until the locking teeth 28 are engaged in the locking rod 22. In this way, the storage tube 21 can no longer rotate, and the storage tube 21 can no longer adjust the length of the safety rope 15. The safety rope 15 can maintain a fixed length.

[0022] In a preferred embodiment, a spring 24 is provided between the side of the storage tube 21 with the retaining teeth 28 and the retaining rod 22, and a threaded fastening ring 25 is provided on the outside of the retaining rod 22.

[0023] With the above structure, by rotating the fastening ring 25 inward, the fastening ring 25 drives the storage cylinder 21 to move closer to the locking rod 22 until the locking tooth 28 is engaged in the locking rod 22. The spring 24 is provided so that when the fastening ring 25 is rotated outward, the spring 24 can automatically open the storage cylinder 21 and the locking rod 22 under the spring action, so that the two can quickly separate.

[0024] In a preferred embodiment, the tooth 28 is provided with a plurality of slots 281, and the slots 281 are matched with the shape of the rod 22.

[0025] With the above structure, when the storage tube 21 is rotated at a small angle, the slot 281 can also correspond to the lever 22.

[0026] In a preferred embodiment, a pull ring 26 is provided above the lever 22, and the wire rope 13 is connected to the pull ring 26.

[0027] With the above structure, the position of the locking lever 22 can always be kept unchanged, while the storage tube 21 and the fixed shaft 23 move relative to the locking lever 22.

[0028] In a preferred embodiment, a baffle 27 is provided on one side of the fixed shaft 23.

[0029] The baffle 27 can block the storage tube 21 and prevent it from falling to one side.

[0030] Example 2: Further explanation in conjunction with Example 1; This embodiment is similar in structure and principle to embodiment 1, so it will not be repeated here. Only the differences from the first embodiment are described. The difference is that a positioning hole 221 is provided on the locking rod 22, and a matching second through hole 251 is provided on the fastening ring 25. A movable insert rod 29 is provided in the second through hole 251.

[0031] With the above structure, after the fastening ring 25 is rotated into place, the insertion rod 29 can be inserted into the positioning hole 221, thereby locking the position of the fastening ring 25 in the original structure. This is equivalent to preventing the threaded connection of the fastening ring 25 from loosening, so that the fastening ring 25 is not easy to change position, thereby locking the length of the safety rope 15.

[0032] The above embodiments are merely preferred technical solutions of this utility model and should not be considered as limitations on this utility model. The protection scope of this utility model should be the technical solution described in the claims, including equivalent substitutions of the technical features described in the claims. That is, equivalent substitutions and improvements within this scope are also within the protection scope of this utility model.
