[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0022] Example 1:
[0023] Please see Figure 1-3This utility model provides a technical solution: a tower crane hook rope breakage protector, comprising: a housing 1, a level 2 fixedly connected to the upper front and upper rear sides of the housing 1, guide wheels 3 provided on both sides of the lower interior of the housing 1, a steel wire rope 4 provided on the surface of the guide wheels 3, the two ends of the steel wire rope 4 extending to the top of the housing 1, a fixing block 5 fixedly connected longitudinally inside the housing 1, an arc-shaped bracket 6 fixedly connected on both sides of the fixing block 5, and a locking assembly 7 located in the housing 1, the locking assembly 7 being used to clamp and fix the steel wire rope 4.
[0024] In this embodiment, when the wire rope 4 breaks, the level 2 will detect that the box 1 is tilted horizontally. At the same time, the hydraulic rod 71 starts to operate, and the hydraulic rod 71 drives the arc-shaped locking block 72 to move.
