[0022] Example 1

[0023] This embodiment provides Figures 1-5 The shown device is a wire rope anti-static device for a tower crane, comprising a tower boom 1 of a tower crane, a winch 2 being provided on the tower boom 1, a base plate 3 being horizontally provided on the right side of the winch 2, the base plate 3 being fixed to the tower boom 1, and an upper surface of the base plate 3 being provided with a herringbone-shaped support rod 4 consisting of a connecting rod 41 and a first telescopic rod 42 connected thereto, one end of the connecting rod 41 being hinged to the base plate 3, and the other end of the connecting rod 41 being connected to a pulley assembly 5, the pulley assembly 5 being grounded to the tower boom 1 through the connecting rod 41 and the base plate 3, the pulley assembly 5 comprising a pulley body 51 and a concave outer shell 52, the outer shell 52 being opened upward, the closed end of the outer shell 52 being hinged to the connecting rod 41, and the end of the first telescopic rod 42 away from the connecting rod 41 being hinged to the base plate 3.

[0024] Before use, the winch 2 and the anti-static device are installed on the tower arm 1, preferably on the counterweight arm of the tower arm 1, and when the steel wire of the winch 2 is needed to drive the lifting hook to lift, the staff starts the winch 2, and the steel wire on the winch 2 moves through the pulley body 51 first, and then moves to the lower side of the tower arm 1 to control the lifting hook to move and lift, wherein the pulley body 51 is grounded through the bottom plate 3 and the connecting rod 41, and can discharge the steel wire passing through the pulley body 51, thereby preventing the static electricity on the steel wire from being too large to cause harm to the staff, and improving the construction safety.

[0025] Further, the pulley body 51 is vertically provided with vertical plates 7 on the front and rear sides, the vertical plates 7 are fixedly connected with the bottom plate 3 at the bottom, a second telescopic rod 8 is horizontally provided between the two vertical plates 7 and the pulley body 51, one end of the second telescopic rod 8 is hingedly connected with the opening end of the shell 52, the other end of the second telescopic rod 8 is hingedly connected with the vertical plate 7, a spring 9 is sleeved on the second telescopic rod 8, one end of the spring 9 is fixedly connected with the shell, and the other end of the spring 9 is fixedly connected with the vertical plate 7.

[0026] When the steel wire rope on the winch 2 moves on the pulley body 51, the steel wire rope will move transversely and reciprocally, so by setting the vertical plate 7 on both sides of the pulley body 51, the second telescopic rod 8 cooperates with the connecting rod 41 and the first telescopic rod 42, not only can make the pulley body 51 on the connecting rod 41 have more support points on both sides, improve the stability of the pulley body 51, but also when the pulley body 51 moves transversely and reciprocally with the steel wire rope, the pulley body 51 can automatically adjust the position with the transverse movement of the steel wire rope, so that the steel wire rope stably contacts with the pulley body 51, realizes that the pulley body 51 moves with the steel wire rope when the steel wire rope moves on the pulley body 51, so that the steel wire rope better contacts and fits with the pulley body 51 when passing through the pulley body 51, and at the same time avoids the steel wire rope from falling off the pulley body 51 with the movement of the winch 2, so as to improve the effect of grounding discharge of the pulley body 51 on the steel wire rope, and the spring 9 on the second telescopic rod 8 can compress the spring 9 when the pulley body 51 moves transversely with the steel wire rope, and the spring force of the spring 9 can assist the pulley body 51 to reset quickly when the pulley body 51 resets with the movement of the steel wire rope, so as to improve the effect of the pulley body 51 on the transverse movement of the steel wire rope. The sleeve ring 6 is sleeved on the connecting rod 41, the sleeve ring 6 is hinged with the first telescopic rod 42, so that when the steel wire rope moves transversely, in addition to the gravity of the steel wire rope, there will be a downward component force acting on the pulley body 51, so that the pulley body 51 moves downward, and when the pulley body 51 moves downward, the connecting rod 41 rotates, and the first telescopic rod 42 rotates through the sleeve ring 6, so as to avoid the connecting rod 41 and the first telescopic rod 42 from supporting the pulley body 51, which can damage the connecting rod 41 and the pulley body 51 due to their own rigidity, and reduce the service life, and the second spring on the connecting rod can provide a counterforce to the sleeve ring 6 when the sleeve ring 6 moves with the connecting rod 41, so as to make it quickly recover, and the second spring can also play an auxiliary supporting role.

[0027] Further, the left side of the closed end of the shell 52 is fixedly connected with the fixed plate 10, the upper surface of the fixed plate 10 is fixedly connected with the fixed rod 11, the fixed rod 11 is fixedly connected with the concave protective frame 12, the protective frame 12 is arranged in parallel with the concave shell 52, and the opening end of the protective frame 12 is inwardly protruding.

[0028] The distance between the position height of the protection frame 12 and the pulley body 51 can be at least one steel wire rope, so that the steel wire rope can be in close contact with the pulley body 51 when the steel wire rope passes between the pulley body 51 and the shell 52, avoiding long-term movement of the steel wire rope above the pulley body 51, causing wear of the pulley body 51 and reducing the service life. The inwardly protruding opening end of the protection frame 12 can prevent the steel wire rope from falling off the pulley body 51 when the hoist 2 moves, thereby further improving the grounding and discharging effect of the pulley body 51 on the steel wire rope. According to the needs of use, the position of the protection frame 12 on the left side of the pulley body 51 can be adjusted, for example, the protection frame 12 is arranged in front of the left side of the pulley body 51, or the protection frame 12 is arranged above the left side of the pulley body 51, thereby improving the applicability range.

[0029] In summary, the utility model provides a kind of steel wire rope anti-static device of tower crane, solve the problem that due to the electromagnetic field of construction periphery, current is larger, hoist 2 on tower crane is used for long time, the steel wire rope on hoist 2 can be brought high voltage static electricity, so that staff is easy to be high voltage static electricity when construction, leading to the safety of worker when construction cannot be guaranteed.

[0030] The above content is a further detailed description of the utility model in combination with specific preferred embodiments, and cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary skilled persons in the technical field to which the utility model belongs, without departing from the concept of the utility model, a number of simple deductions or substitutions can be made, which should be regarded as belonging to the protection scope of the utility model.
