[0021] Example 1

[0022] This embodiment provides Figure 1 to Figure 4 The steel wire rope anti-static device of a tower crane shown in the figure comprises a tower arm 1 of a tower crane, a winch 2 is arranged on the tower arm 1, a vertical pole 3 is vertically arranged on the right side of the winch 2, the lower end of the vertical pole 3 is fixedly connected to the tower arm 1, a connecting rod 4 is arranged on the upper end of the vertical pole 3, a pulley assembly 5 is connected to the end of the connecting rod 4 away from the vertical pole 3, the pulley assembly 5 is grounded to the tower arm 1 through the vertical pole 3 and the connecting rod 4, the pulley assembly 5 comprises a pulley body 51 and a concave shell 52, the shell 52 is opened upward, the pulley body 51 is installed at the open end of the shell 52, and the closed end of the shell 52 is fixedly connected to the connecting rod 4.

[0023] Before use, first install the winch 2 and the anti-static device on the tower arm 1, wherein it is best to install the winch 2 and the anti-static device on the counterweight arm of the tower arm 1. After the installation is completed, when it is necessary to use the wire rope of the winch 2 to drive the hook for lifting, the staff starts the winch 2 to make the wire rope on the winch 2 move through the pulley body 51 first. After the wire rope passes through the pulley body 51, it is then moved to the bottom of the tower arm 1 to control the hook to move and lift. The pulley body 51 is grounded through the vertical pole 3 and the connecting rod 4, which can discharge the wire rope passing through the pulley body 51, thereby preventing excessive static electricity on the wire rope from causing harm to the staff, thereby improving construction safety.

[0024] Furthermore, the upper end of the vertical rod 3 is hinged to the connecting rod 4 through a rotating assembly 6, and the connecting rod 4 is tilted with the left side lower and the right side higher. The rotating assembly 6 includes a vertically arranged rotating rod 61, and the rotating rod 61 is located between the upper end of the vertical rod 3 and the connecting rod 4. The lower end of the rotating rod 61 is rotatably connected to the upper end of the vertical rod 3, and the upper end of the rotating rod 61 is rotatably connected to a first connecting member 62, and the upper end of the first connecting member 62 is hinged to the connecting rod 4, and the connecting rod 4 is fixedly connected to a second connecting member 7; a bottom plate 8 is horizontally arranged on the right side of the vertical rod 3, and the bottom plate 8 is fixed on the tower arm 1, and a slider 9 is horizontally slidably connected to the upper surface of the bottom plate 8, and a baffle 10 is vertically arranged on the left side of the slider 9. The baffle 10 is fixed on the base plate 8, and 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 horizontally arranged second telescopic rod 13 is fixedly connected to the left side of the slider 9, and the left end of the second telescopic rod 13 is fixedly connected to the right side surface of the baffle 10. The spring 11 is sleeved on the second telescopic rod 13, and a first telescopic rod 12 is arranged between the slider 9 and the second connecting member 7. Both ends of the first telescopic rod 12 are ball-jointed with connecting blocks 15, and both ends of the first telescopic rod 12 are hinged to the slider 9 and the second connecting member 7 through the connecting blocks 15, respectively.

[0025] By cooperating with the vertical rod 3, the pulley body 51 on the connecting rod 4 can have an additional support point. By cooperating with the spring 11, the slider 9 and the baffle 10, when the pulley body 51 is acted downward by its own gravity, the first telescopic rod 12 exerts a force on the slider 9 to move rightward to stretch the spring 11. The spring 11 converts the tension received into elastic force to exert a force on the slider 9 to the left, so that the slider 9 remains stationary, so that the first telescopic rod 12 can fix and support it.

[0026] When the wire rope on the winch 2 moves on the pulley body 51, the wire rope will move back and forth laterally. Therefore, through the cooperation of the rotating rod 61 of the rotating assembly 6 and the first connecting member 62, the connecting rod 4 can rotate in the horizontal direction around the vertical rod 3 as the center when the wire rope on the pulley body 51 moves laterally. The first telescopic rod 12 rotates with the connecting rod 4 through the second connecting member 7, and the slider 9 connected to the first telescopic rod 12 cooperates with the second telescopic rod 13 and the baffle 10, so that when the first telescopic rod 12 moves with the connecting rod 4, the slider 9 is prevented from moving out of a straight line. A slide groove 14 is horizontally opened on the upper surface of the bottom plate 8, and the slide groove 14 is located on the right side of the second telescopic rod 13. The slider 9 slides in the slide groove 14, thereby further limiting the movement of the slider 9;

[0027] When the wire rope moves laterally on the pulley body 51, a downward component force will be applied to the pulley body 51, and the pulley body 51 will drive the connecting rod 4 to rotate around the first connecting piece 62. The connecting rod 4 drives the first telescopic rod 12 to move through the second connecting piece 7 and the connecting block 15 at the upper end, and the first telescopic rod 12 drives the slider 9 to move horizontally and linearly through the connecting block 15 at the lower end. When the slider 9 moves, the spring 11 is stretched, and the tension received by the spring 11 is converted into elastic force to exert a rightward force on the slider 9, thereby achieving the supporting and fixing effect of the pulley body 51 and the wire rope, and the two ends of the pulley body 51 are gradually contracted and inclined toward the middle, which can not only make the wire rope better contact and fit with the pulley body 51 when passing through the pulley body 51, but also prevent the 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 the grounding discharge of the wire rope.

[0028] In summary, the utility model provides an anti-static device for the wire rope of a tower crane, which solves the problem that due to the electromagnetic field in the construction area and the large current used, the wire rope on the winch 2 on the tower crane will carry high-voltage static electricity when used for a long time, making it easy for workers to be injured by the high-voltage static electricity during construction, resulting in the safety of workers during construction not being guaranteed.

For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
