[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Embodiment: Referring to Figures 1-4 The special hanging basket for the bridge high pier and bent cap support steel plate shown in the figure comprises a load-bearing beam 1 in a rectangular frame structure, which facilitates workers to enter the hanging basket. The four corners of the bottom of the load-bearing beam 1 are fixed with load-bearing frameworks 2. The bottom ends of the four load-bearing frameworks 2 are fixed with a lower basket 3. The side close to the pier column of the lower basket 3 is in a circular arc structure. The intention is that when the hanging basket is used on a cylindrical pier, the hanging basket can better fit the circular arc surface of the pier, reducing the swing of the hanging basket due to the non-fitting with the circular arc surface, so that the hanging basket is more stable and reliable during use. Two step ladders 4 are fixed between the load-bearing beam 1 and the lower basket 3. The step ladders 4 are fixedly installed on the load-bearing frameworks 2. Two load-bearing trusses 5 are slidably sleeved on the outside of the load-bearing beam 1. The two load-bearing trusses 5 are located at the top of the pier column and are arranged in parallel. The hanging basket can be hung on the concrete at the top of the pier column. Two steel wire ropes 6 are installed on the load-bearing beam 1. The two steel wire ropes 6 fixed on the load-bearing beam 1 are pulled to the rear of the pier embedded bar and are locked by a buckle, so that the hanging basket can still be hung on the pier top when subjected to external force, serving as a safety reserve. An upper safety guardrail 7 is fixed at the top of the load-bearing beam 1.

[0023] The construction personnel enter the upper safety guardrail 7 from the top of the pier, then climb into the lower basket 3 from the step ladder 4, and cooperate with the crane to pass the steel plate into the pier column. The embedded steel rod is used as the main load-bearing support of the temporary support of the bent cap construction. The vertical height between the load-bearing beam 1 and the lower basket 3 is 1.5 m, which meets the height requirement of most steel rods. The position of the steel rod construction is not disturbed, and the personnel can no longer sit in the crane hanging basket to pass the steel rod as in the past. From the perspective of safe construction, the crane hanging personnel is illegal. From the perspective of real safety risk, the hanging personnel in the air exists high-risk safety risks such as overturning of the hanging basket, breaking of the steel wire rope, and crane failure. The use of the hanging basket can make the workers walk to the top of the pier through the safe ladder, enter the hanging basket after the hanging basket is installed and locked on the top of the pier, and the whole process no longer uses the crane or tower crane to hang the personnel, effectively avoiding the safety risk.

[0024] The inside of the load-bearing truss 5 is fixed with a plurality of reinforcing ribs 8, the plurality of reinforcing ribs 8 are arranged in linear arrangement, form a couple of forces, so that the two load-bearing trusses 5 can be stably hung on the top of the pier column, without increasing other force members, the load-bearing capacity of the hanging basket can be ensured, since the distance between the pre-buried steel bars of the pier column can be inconsistent, in order to improve the application range of the hanging basket, the position of the two load-bearing trusses 5 on the load-bearing beam 1 is moved, the distance between the two load-bearing trusses 5 is adjusted, so that the two load-bearing trusses 5 can adapt to the width of the pre-buried steel bars of various pier columns, the bottom of the inside of the lower basket 3 is fixed with a bottom plate 9, so that the workers can step on the bottom plate 9 after entering the lower basket 3, and the application has been successfully applied in the highway project from Huize to Qiaojia.

[0025] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
