DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, purposes and effects of the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0023] Please refer to Figures 1 to 4 The utility model provides a technical scheme: a coiled display and placement device, including placement table 1 and display and placement cylinder group 2, display and placement cylinder group 2 includes cylinder seat 21 and the winding drum 22 rotationally connected in cylinder seat 21, when implementing, the cylinder seat 21 is the slot-shaped structure, and the both ends of the winding drum 22 are fixedly connected with the support shaft rotationally connected with both sides in the cylinder seat 21, and the outside of the cylinder seat 21 is installed with the drive motor set, and the output shaft of the drive motor set is fixedly connected with one of the support shafts, and the winding drum 22 is wound with the steel wire rope, and the winding drum 22 realizes the function of collecting and placing the steel wire rope by reversing.

[0024] The bottom of the barrel seat 21 is fixedly connected with a positioning disc 211, and the top of the placing table 1 is fixedly connected with a positioning sleeve 11 which is sleeved outside the positioning disc 211, and the positioning sleeve 11 and the positioning disc 211 are rotationally connected. In use, it is ensured that the steel wire rope connected to the winding drum 22 is in a non-vertical state. In this embodiment, the steel wire rope close to the winding drum 22 is taken as an example to be described in a horizontal state. When the positioning disc 211 is controlled to rotate, the axis of the winding drum 22 and the steel wire rope are in a non-vertical state. At this time, when the winding drum 22 winds the steel wire rope, the steel wire rope is uniformly wound on the winding drum 22 and does not appear to be gathered and wound. Therefore, periodic control of the back-and-forth rotation of the positioning disc 211 can uniformly wind the entire steel wire rope.

[0025] The placing table 1 is provided with a control mechanism 3 for controlling the rotation of the positioning disc 211.

[0026] Specifically, the control mechanism 3 comprises a slot-shaped frame 31 and a swing control combination 32. The outer circumferential wall of the positioning disc 211 is fixedly connected with two symmetrically distributed positioning shafts 2111. The slot-shaped frame 31 is parallel to the positioning disc 211, and the open end of the slot-shaped frame 31 is fixedly connected with the two positioning shafts 2111 on the positioning disc 211. This arrangement makes the driving force received by the positioning disc 211 more uniform when the positioning disc 211 rotates.

[0027] Further, the swing control combination 32 comprises a rotating disc 321 and a control motor 322. The rotating disc 321 is arranged on the placing table 1 and has an eccentric shaft 3211 connected to one side thereof. The eccentric shaft 3211 is rotationally and slidably connected with the slot-shaped frame 31. In specific implementation, the outer side of the cross beam on the slot-shaped frame 31 is preferably welded with an arm 311. A waist-shaped hole 3111 is formed in the arm 311. A sliding block 31111 is arranged in the waist-shaped hole 3111. A connecting hole 311111 is formed in one side of the sliding block 31111 and is rotationally connected with the eccentric shaft 3211. Thus, the rotation and sliding connection of the eccentric shaft 3211 and the arm 311 is realized. The control motor 322 is fixedly arranged on the placing table 1 and has an output shaft fixedly connected with the rotating disc 321. In specific implementation, the upper end surface of the placing table 1 is preferably welded with a door-shaped frame 12. The control motor 322 is fixedly arranged in the door-shaped frame 12. The other side of the rotating disc 321 is welded with a connecting shaft 3212 rotationally connected with the top of the door-shaped frame 12. The top of the door-shaped frame 12 is welded with a limiting sleeve rotationally connected with the connecting shaft 3212. The connecting shaft 3212 is fixedly connected with the output shaft of the control motor 322. Thus, when the rotating disc 321 rotates one round, the eccentric shaft 3211 drives the slot-shaped frame 31 to swing back and forth once, thereby changing the inclination direction of the winding drum 22 relative to the steel wire rope once.

[0028] The eccentric shaft 3211 and the rotating disc 321 are in sliding fit, and the sliding direction is along the radial direction of the rotating disc 321. One side of the rotating disc 321 is rotationally connected with a screw rod 3213 which is in penetrating and screwing fit with the eccentric shaft 3211. In a specific implementation, a support plate which is rotationally connected with the screw rod 3213 can be welded on one side of the rotating disc 321, and then a screw sleeve which is sleeved on the screw rod 3213 is welded on the eccentric shaft 3211. When the screw rod 3213 rotates, the position of the eccentric shaft 3211 in the radial direction of the rotating disc 321 can be adjusted. Such a setting has the effect of indirectly adjusting the inclination angle of the winding drum 22 relative to the steel wire rope. For example, when the steel wire rope is under a large stress, the angle of rotation of the positioning disc 211 needs to be controlled to be reduced, and vice versa. The purpose is to make the steel wire rope with different loads be uniformly wound on the winding drum 22. One end of the screw rod 3213 is welded with a handle 32131. The handle 32131 is a handheld part. The handle 32131 can control the rotation of the screw rod 3213.

[0029] Working principle: when winding the steel wire rope, the winding drum 22 is controlled to rotate and wind, and then the control motor 322 is started to rotate the rotating disc 321. The eccentric shaft 3211 drives the groove-shaped frame 31 to swing through the arm 311, and then drives the positioning disc 211 to rotate. At this time, the axis of the winding drum 22 is in a non-vertical inclined state relative to the steel wire rope. At this time, the steel wire rope can be uniformly wound on the winding drum 22, and the gathering winding phenomenon does not occur. When the steel wire rope approaches one end of the winding drum 22, the rotating disc 321 is controlled to rotate by 180° to change the direction of the inclination of the winding drum 22 relative to the steel wire rope, so as to guide the steel wire rope to be uniformly wound on the winding drum 22.

[0030] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution. The description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments which can be understood by those skilled in the art.
