Detailed Description
The present invention will be further described with reference to the accompanying drawings and examples.
Referring to fig. 1, 2 and 3, the device for removing the bottom die of the cantilever arm of the bridge deck comprises a main structure consisting of an underframe 1, a support frame 2 and a cantilever arm 4, wherein the underframe 1, the support frame 2 and the cantilever arm 4 are all made of 20b I-steel, the three are welded together to form a frame supporting structure, the support frame 2 is provided with an X-shaped support 3, and the X-shaped support 3 is made of 16# channel steel and is welded together with the support frame 2. The underframe 1 is provided with an anti-tilting bayonet 6 which is fixedly connected with the bridge deck hanger 12, and the anti-tilting bayonet 6 is arranged at the tail end of the lower part of the underframe 1. The cantilever arm 4 is welded on the upper part of the support frame 2 and extends forwards horizontally. The two sets of winch sets 7 are arranged on the main body framework supporting structure in parallel, wherein the winch 7-1 is fixed on the bottom frame 1, the rear pulley 5-1 and the front pulley 5 are arranged on the cantilever arm 4 through the pulley shaft 9, the front pulley 5 is positioned at the front end part of the cantilever arm 4, one end of the steel wire rope 8 is connected with the winch 7-1, the other end of the steel wire rope 8 sequentially bypasses the rear pulley 5-1 and the front pulley 5 to droop, and the droop end is connected with the hook 17.
