Description

Technical Field

[0001] The utility model relates to the technical field of hooks, in particular to a hook for construction engineering. Background Art

[0002] The hook, also known as the lifting hook in English, is the most common type of lifting device in lifting machinery. The hook is often suspended on the wire rope of the lifting mechanism with the help of pulleys and other components. The single hook is simple to manufacture and easy to use, but the force is not good. It is mostly used in work places with a lifting weight of less than 80 tons; when the lifting weight is large, a double hook with symmetrical force is often used. The laminated hook is made of several pieces of cut and formed steel plates riveted together. When cracks appear on individual plates, the entire hook will not be damaged. It has better safety, but the deadweight is large. It is mostly used in cranes with large lifting weights or lifting molten steel buckets. The hook is often impacted during operation and must be made of high-quality carbon steel with good toughness. However, the existing hooks for construction projects still have some shortcomings, such as the inability to prevent the steel cable from being broken due to the instantaneous force at the moment of lifting, and the hook cannot provide better lighting at night.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Embodiment 1

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The utility model provides a technical solution: a hook for construction engineering, comprising a shell 1, a movable plate 10 is slidably connected inside the shell 1, a plurality of groups of sliding columns 5 are fixedly connected above the movable plate 10, a fixed plate 4 is fixedly connected above the shell 1, the sliding columns 5 penetrate the fixed plate 4 and are fixedly connected to an upper plate 6, and a fixed hook 7 is fixedly connected above the upper plate 6.

[0022] Three groups of springs 9 are fixedly connected to the bottom of the movable plate 10 , an oil inlet hole 14 is opened in the middle of the movable plate 10 , and a column 15 is fixedly connected to the upper surface of the movable plate 10 .

[0023] A hand-cranked generator 18 is fixedly connected to the upper side of the movable plate 10, one end of which is fixedly connected to an intermediate shaft 17, and the intermediate shaft 17 passes through the column 15 and is fixedly connected to a turntable 16.

[0024] The working principle of the hook for construction engineering based on the first embodiment is: when the hook is hoisted, the steel cable is first fixed above the fixed hook 7, and then during lifting, the fixed hook 7 first pulls the upper plate 6, and then the upper plate 6 pulls the sliding column 5, and then the sliding column 5 is fixedly connected to the movable plate 10 to pull the movable plate 10 to move upward. Since the interior of the outer shell 1 is filled with flame-retardant oil, during the rising process of the movable plate 10, the oil will pass through the position of the oil inlet 14. Due to the resistance encountered on the way, the movement is not smooth, thereby generating a damping feeling to prevent the steel cable on the upper plate 6 from suddenly being subjected to a huge tensile force and breaking. When the lifting is completed, the movable plate 10 is reset under the tension of the spring 9, which is convenient for the next use, and prevents the surrounding staff from being injured after the steel cable breaks, and better protects the steel cable.

[0025] Embodiment 2

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 Compared with the first embodiment, the utility model provides a hook for construction engineering. The present embodiment further includes: a battery 12 is fixedly connected to the bottom of the fixing plate 4, and a plurality of groups of lamp beads 13 are fixedly connected to the bottom of the fixing plate 4.

[0027] The turntable 16 is rotatably connected to the inside of the column 15 . The lower part of the housing 1 is fixedly connected to the rotating shaft 2 . The interior of the rotating shaft 2 is fixedly connected to the shaft body 11 .

[0028] The outer wall of the shaft body 11 is rotatably connected with a hook 3 , an inner cavity 8 is opened inside the outer shell 1 , and the other end of the spring 9 is fixedly connected to the bottom of the inner cavity 8 .

[0029] The working principle of the hook for construction engineering based on the second embodiment is: by setting the turntable 16, when the hook rises, the oil will pass through the position of the oil inlet 14, and the oil will flush the turntable 16, thereby driving the turntable 16 to rotate inside the column 15, and the intermediate shaft 17 is rotated by the rotation of the column 15, and then transmitted to the inside of the hand-cranked generator 18, so that the magnetic field inside the hand-cranked generator 18 produces relative movement, thereby generating current in the conductor. In this way, mechanical energy is converted into electrical energy, and when the current generated by the hand-cranked generator 18 is transmitted to the inside of the battery 12, the battery 12 then supplies energy to the lamp bead 13, which can better illuminate the staff, making it more convenient to hoist at night, and can also make the staff on the ground better pay attention to the hook to prevent being injured by the hook.
