Description

TECHNICAL FIELD

[0001] The utility model belongs to hoisting construction field, especially involves a prefabricated concrete wave protection wall hoisting device. BACKGROUND

[0002] The prefabricated concrete is made in the factory, and is transported to the construction site after forming. On the one hand, the prefabricated concrete has the advantages of controllable quality, safe structure, reusable mold, green environmental protection and the like. On the other hand, after the prefabricated concrete is used in the construction site, the construction period can be greatly shortened without being affected by seasons and weather.

[0003] The prefabricated wave protection wall is used in reservoirs, river channels and dams to play the role of wave protection, flood protection and water resistance. Since the concrete wave protection wall is heavy, it must be installed by a hoisting device (a lifting ring is usually pre-buried at the top of the wave protection wall for construction), and the wave protection wall is preferably kept horizontal when being placed. The existing hoisting device includes a lifting hook and at least two ropes. When hoisting the wave protection wall, the wave protection wall is occasionally inclined, and the hoisting device cannot adjust the degree of inclination, which is not conducive to subsequent placement. SUMMARY

[0004] The utility model aims at providing a prefabricated concrete wave protection wall hoisting device capable of adjusting the degree of inclination of the wave protection wall.

[0005] To achieve the above-mentioned purpose, the utility model provides a prefabricated concrete wave protection wall hoisting device, which comprises an adapter plate and first, second and third ropes uniformly distributed around the adapter plate. The first rope is located above the adapter plate and is used to connect a crane. The second and third ropes are located below the adapter plate and are used to hoist the wave protection wall. A telescopic threaded pull rod is arranged in the middle section of the third rope. After the threaded pull rod is twisted, the length of the threaded pull rod can be changed, so that the length of the third rope can be adjusted, and finally the degree of inclination of the hoisted wave protection wall can be adjusted.

[0006] As an improvement of the above-mentioned scheme, the threaded pull rod comprises nuts at the two ends and a bolt in the middle. One end of the nut is provided with a threaded hole, and the other end is provided with a U-shaped sleeve ring. The two ends of the bolt are provided with threads, and the middle is provided with a prism with a diameter larger than the two ends.

[0007] As an improvement of the above-mentioned scheme, the length of the threads at the two ends of the bolt is greater than the length of the threads of the nut, so that the two ends of the bolt protrude from the nut.

[0008] As an improvement of the above-mentioned scheme, the length of the threads of the bolt is 4-6 cm, and the length of the threads of the nut is 3-5 cm.

[0009] As an improvement of the above scheme, the bottom of the second rope and the third rope is provided with a lifting hook, the inner side of the lifting hook is hinged with an anti-off sleeve rod.

[0010] The utility model has the advantages of fixed length of the second rope and telescopic third rope, simple structure, equal length of the second rope and the third rope in the initial state, adjustment of the length of the third rope to restore the wave-preventing wall to the horizontal state when the wave-preventing wall is tilted due to errors, convenient adjustment of the third rope with a common wrench.

If the terms "first", "second", "third" are described, they are only for the purpose of description and distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features or the sequence of indicated technical features.

[0015] In the description of the utility model, it is necessary to explain, unless another explicit provision and limitation, the term '' install '' '' connect '' '' set '' should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium, can be two elements inside the intercommunication, for the ordinary skill in the art, the above-mentioned term can be understood according to the specific meaning of the utility model in the specific situation. The embodiment is described below according to the overall structure of the utility model.

[0016] Referring to Figure 1 The utility model discloses a precast concrete wave protection wall hoisting device, include: adapter plate 10 and the first rope 11, second rope 12, third rope 13 of the even distribution in the periphery of adapter plate 10, first rope 11 is located the top of adapter plate 10, is used to connect crane, second rope 12 and third rope 13 are located the lower left and right sides of adapter plate 10, are used for hoisting wave protection wall respectively, the middle section of third rope 13 is provided with telescopic screw pull rod, after twisting screw pull rod, the length of screw pull rod can be changed, thereby adjust the length of third rope 13, finally adjust the inclination degree of hoisted wave protection wall.

[0017] Second rope 12 length is fixed, and third rope 13 has telescopic characteristics, and such design makes the device structure simple. In the initial state, the length of second rope 12 and third rope 13 is equal. When hoisted wave protection wall appears inclination due to error, the length of third rope 13 can be adjusted to make wave protection wall restore to the horizontal state.
