[0022] Embodiment 1

[0023] This embodiment provides as Figures 1 to 4An anti-static device for the steel wire rope of a tower crane shown in the figure, which includes the boom 1 of a tower crane. A winch 2 is provided on the boom 1. A vertical pole 3 is provided on the right side of the winch 2. The lower end of the pole 3 is fixedly connected to the boom 1. A first connecting rod 4 is provided at the upper end of the pole 3. One end of the first connecting rod 4 away from the pole 3 is connected to a pulley assembly 5. The pulley assembly 5 is grounded through the pole 3 and the first connecting rod 4 with the boom 1. The pulley assembly 5 includes a concave outer shell 52 and a pulley body 51. The outer shell 52 is arranged with the opening facing upward. The closed end of the outer shell 52 is fixedly connected to the first connecting rod 4.

[0024] Before use, first install the winch 2 and the anti-static device on the boom 1. Among them, it is best to install the winch 2 and the anti-static device on the counterweight boom of the boom 1. After installation, when it is necessary to drive the hook to lift by the steel wire rope of the winch 2, the staff starts the winch 2, so that the steel wire rope on the winch 2 first moves through the pulley body 51. After the steel wire rope passes through the pulley body 51, it then moves under the boom 1 to control the movement of the hook for lifting. Among them, the pulley body 51 is grounded through the pole 3 and the first connecting rod 4, which can discharge the steel wire rope passing through the pulley body 51, so as to prevent the static electricity on the steel wire rope from being too large and causing harm to the staff, thereby improving the construction safety.

[0025] Furthermore, the upper end of the pole 3 is hinged to the first connecting rod 4 through a rotating assembly 6. The rotating assembly 6 includes a vertically arranged rotating rod 61. The rotating rod 61 is located between the upper end of the pole 3 and the first connecting rod 4. The lower end of the rotating rod 61 is rotatably connected to the upper end of the pole 3. The upper end of the rotating rod 61 is rotatably connected to a first connecting member 62. The upper end of the first connecting member 62 is hinged to the first connecting rod 4. A second connecting member 7 is fixedly connected to the first connecting rod 4; a bottom plate 8 is horizontally provided on the right side of the pole 3. The bottom plate 8 is fixed on the boom 1. A slider 9 is slidably connected to the upper surface of the bottom plate 8. A baffle 10 is vertically provided on the left side of the slider 9. The lower end of the baffle 10 is fixed on the bottom plate 8. A spring 11 is horizontally arranged between the slider 9 and the baffle 10. One end of the spring 11 is fixedly connected to the slider 9, and the other end of the spring 11 is fixedly connected to the baffle 10. A second connecting rod 12 is provided between the slider 9 and the second connecting member 7. One end of the second connecting rod 12 is hinged to the slider 9, and the other end of the second connecting rod 12 is hinged to the second connecting member 7.

[0026] By means of the cooperation between the arranged second connecting rod 12 and the vertical rod 3, an additional support point can be provided for the pulley body 51 on the first connecting rod 4. Also, through the cooperation between the spring 11, the slider 9 and the baffle 10, when the pulley body 51 acts downward under its own gravity, a rightward acting force on the slider 9 is generated through the second connecting rod 12 to stretch the spring 11. The spring 11 converts the received tensile force into elastic force to exert a leftward acting force on the slider 9, thereby keeping the slider 9 stationary and enabling the second connecting rod 12 to fixedly support it. Among them, the left side of the slider 9 is ball-joint connected to a horizontally arranged telescopic rod 13, and the left end of the telescopic rod 13 is ball-joint connected to the right side surface of the baffle 10. The spring 11 is sleeved on the telescopic rod 13, which can prevent the spring 11 from bending and tilting when being compressed;

[0027] When the steel wire rope on the winch 2 moves on the pulley body 51, the steel wire rope will move horizontally back and forth. Therefore, through the cooperation between the rotating rod 61 of the arranged rotating assembly 6 and the first connecting piece 62, when the first connecting rod 4 moves horizontally along with the steel wire rope on the pulley body 51, it can rotate horizontally around the vertical rod 3 as the center. The second connecting rod 12 rotates together with the first connecting rod 4 through the second connecting piece 7, causing the slider 9 connected to the second connecting rod 12 to move on the bottom plate 8. When the slider 9 moves, a chute 14 is horizontally opened on the upper surface of the bottom plate 8. The chute 14 is located on the right side of the telescopic rod 13, and the slider 9 slides in the chute 14. The width of the chute 14 is greater than the width of the slider 9. The left side of the chute 14 is set as an inwardly concave arc-shaped side, and the arc-shaped side of the chute 14 is concentric with the rotating rod 61. The cooperation between the spring 11 and the telescopic rod 13 enables the spring 11 and the telescopic rod 13 to quickly reset the slider 9 when the slider 9 moves to the front and rear ends of the arc-shaped side of the chute 14. Thus, when the steel wire rope on the winch 2 moves on the pulley body 51, the pulley body 51 can automatically adjust its position along with the horizontal movement of the steel wire rope, so that the steel wire rope can stably remain in contact with the pulley body 51. And by setting the pulley body 51 to gradually contract and incline from both ends to the middle, the steel wire rope can better contact and fit with the pulley body 51 when passing through the pulley body 51, and at the same time, it can prevent the steel wire rope from falling off the pulley body 51 as the winch 2 moves, thereby further improving the effect of the pulley body 51 on grounding and discharging the steel wire rope.

[0028] Further, a chute 14 is horizontally opened on the upper surface of the bottom plate 8. The chute 14 is located on the right side of the telescopic rod 13, and the slider 9 slides in the chute 14. The left side of the chute 14 is set as an inwardly concave arc-shaped side, and the arc-shaped side of the chute 14 is concentric with the rotating rod 61.

[0029] By means of the arranged chute 14, the slider 9 moves in the chute 14, and by setting the left side wall of the chute 14 as an arc-shaped side, the slider 9 can better fit and move when rotating around the rotating shaft.

[0030] In summary, the present utility model provides an anti-static device for the steel wire rope of a tower crane, which solves the problem that due to the electromagnetic field around the construction site and the relatively large current used, when the winch 2 on the tower crane is used for a long time during construction, the steel wire rope on the winch 2 will carry high-voltage static electricity, making it easy for the staff to be injured by the high-voltage static electricity during construction, resulting in the lack of guarantee for the safety of workers during construction.

For those of ordinary skill in the technical field to which the present utility model belongs, without departing from the concept of the present utility model, several simple deductions or substitutions can still be made, and all should be regarded as belonging to the protection scope of the present utility model.
