TECHNICAL FIELD
[0001] The application relates to the hoisting technology of steel sheet piles and particularly relates to a steel sheet pile hoisting structure for deep foundation pit construction. BACKGROUND
[0002] When the steel sheet pile is hoisted, a worker needs to install a hoisting hook at a rolled position on the side of the steel sheet pile. After the hoisting is completed, the hooks at the two ends of the steel sheet pile are sequentially removed. After the hooks are removed, the hooks are moved by a hoisting rope. However, since the end of the hook is outwardly bent and extended and the outside is not shielded, when the hoisting rope moves the hook, the end of the hook is freely hooked on the side of the steel sheet pile. After the rope and the hook are straightened, the hook slides off the steel sheet pile, which causes the hook to swing greatly and causes the worker to be injured, or the hook slides off the steel sheet pile after the steel sheet pile is lifted, which not only causes the hook to swing greatly but also causes the steel sheet pile to fall rapidly and be damaged.
[0003] Therefore, the inventor needs to design a new steel sheet pile hoisting structure to overcome the above problems. SUMMARY
[0004] The main purpose of the application is to provide a steel sheet pile hoisting structure for deep foundation pit construction to solve the problem that the steel sheet pile is easily slid off the hook in the related art.

[0009] Optionally, the steel sheet pile hoisting hook is fixedly connected with a guide inclined block on one side of the connecting shaft.
[0010] Compared with the prior art, the steel sheet pile hoisting structure for deep foundation pit construction has the beneficial effects that:
[0011] With the cooperation of the reset spring, the connecting plate and the traction rope, the hook shielding rod can be automatically turned over and reset to the outside of the steel sheet pile hoisting hook after the steel sheet pile hoisting hook is taken off from the steel sheet pile by the staff, so that the steel sheet pile hoisting hook is prevented from being hooked on the steel sheet pile or other workpieces in the site again when the hoisting equipment pulls the steel sheet pile hoisting hook, thereby avoiding the staff from being injured due to the large swing of the steel sheet pile hoisting hook caused by the falling of the steel sheet pile hoisting hook and the steel cable after being stretched straight, and the cooperation of the upper support protrusion and the lower support protrusion enables the steel sheet pile hoisting hook to be tilted to the rear side, so that the hook shielding rod is in a suspended state, and the turning over and resetting of the hook shielding rod are prevented from being hindered.

Specifically, after the hook shielding rod 2 is turned over and opened, the position of the connecting plate 31 corresponds to the damping pad sleeve 33, the connecting plate 31 is subjected to the elastic force of the reset spring 3 and the resistance between the connecting plate 31 and the damping pad sleeve 33, so as to reduce the working speed of the connecting plate 31, so that after the hook shielding rod 2 is turned over and opened by the worker, the steel sheet pile hoisting hook 1 is hooked on the steel sheet pile during the process of hoisting the steel sheet pile, it is not necessary to manually limit the hook shielding rod 2 all the time, the supporting pad sleeve 34 which is flush with the damping pad sleeve 33 can play the role of cushioning, so that there is no concave-convex difference in the movement range of the connecting plate 31, so that the connecting plate 31 can slide smoothly.
[0029] The steel sheet pile hoisting hook 1 is fixedly connected with the guide inclined block 5 on one side, and the guide inclined block 5 is located on one side of the connecting shaft 21. Specifically, by arranging the guide inclined block 5, the recess at the position of the connecting shaft 21 and the steel sheet pile hoisting hook 1 can be shielded, so as to avoid that the connecting shaft 21 is hooked on the steel sheet pile, and a gap is left between the guide inclined block 5 and the connecting shaft 21, so that the guide inclined block 5 does not hinder the rotation of the connecting shaft 21.
[0030] Working principle and use process: before hoisting the steel sheet pile, the worker manually turns over the hook shielding rod 2, then hooks the hook shielding rod 2 on the steel sheet pile, the hook shielding rod 2 will pull the traction rope 32 during the turning over process, so as to pull the connecting plate 31 to compress the reset spring 3, after the hoisting of the steel sheet pile is completed, the worker removes the steel sheet pile hoisting hook 1 from the steel sheet pile, after the hook shielding rod 2 loses the limiting, the reset spring 3 resets under the action of its own elastic force, the hook shielding rod 2 is automatically turned over and reset and intercepted outside the steel sheet pile hoisting hook 1 by means of the connecting plate 31 and the traction rope 32, so as to avoid that the steel sheet pile hoisting hook 1 is hooked on the steel sheet pile or the remaining workpieces in the site again when the hoisting equipment lifts the steel sheet pile hoisting hook 1, the upper supporting convex point 4 and the lower supporting convex point 41 cooperate to make the steel sheet pile hoisting hook 1 be able to fall backward when placed on the ground, so that the hook shielding rod 2 is in a suspended state, so as to avoid that the turning over and resetting of the hook shielding rod 2 is hindered.
