Description

Propaganda scroll lifting device

Technical Field

The utility model belongs to the technical field of suspension fixing devices, and particularly relates to a propaganda banner lifting device.

Background

When the vertical scroll is required to be lifted and installed, a manual pulling rope is usually used at present, but pulleys and steel wires in the manual pulling rope device are easy to rust and the like due to perennial wind and rain, so the manual pulling rope has the problems of difficult holding, low lifting efficiency in installation, difficult positioning and the like; when the electric lifting mode is adopted, the electric lifting device is arranged outdoors, so that more faults are easy to occur.

Disclosure of Invention

The utility model aims to provide the lifting device for lifting the vertical propaganda banner, which has a simple structure and is easy to operate, the problem in the traditional manual pulling rope lifting is solved, and the installation workload is reduced.

The utility model adopts the technical scheme that: a propaganda scroll lifting device comprises a lifting rope, a scroll upper supporting device, a winding device, a guide rope, an upper pulley, an upper fixing frame and a lower fixing frame; the upper fixing frame and the lower fixing frame are both arranged on the wall body, and guide ropes are arranged between the two ends of the upper fixing frame and the lower fixing frame; an upper pulley is arranged on the upper fixing frame, and a winding device is arranged on the lower fixing frame; a limiting device is arranged on the lower fixing frame and used for limiting the rotation of the winding device; the winding device is wound with a lifting rope, the lifting rope is connected to the scroll upper supporting device between the upper fixing frame and the lower fixing frame through an upper pulley, and two ends of the scroll upper supporting device slide on the guide rope.

Further, the winding device comprises a bearing, a handle, a rotating shaft and a clamping groove wheel, wherein the bearing is arranged below the lower fixing frame, the rotating shaft is arranged on the bearing, the rotating shaft penetrates through the clamping groove wheel, and the handle is connected with the rotating shaft.

Further, a limiting hole is formed in the periphery of the rotation center of the clamping groove wheel.

Further, the limiting device comprises a limiting handle, a limiting pin and a pin sleeve, wherein the pin sleeve is arranged on the lower fixing frame, the limiting pin is arranged in the pin sleeve, and the limiting handle is vertically arranged on the limiting pin; the limit pin is matched with a limit hole on the clamping grooved wheel.

The utility model has the beneficial effects that:

1. the utility model adopts the mode of manual winding drum and rolling bearing to wind the steel wire rope, and uses the length of the handle as a lever, thereby saving more labor and being convenient when lifting the scroll;

2. the side surface of the clamping grooved wheel is provided with 16 limiting holes, so that the adjusting height can be easily and effectively adjusted and positioned at any time.

3. The self-locking design in the limiting device is safer, and when the limiting pin is inserted into the limiting hole, the limiting handle slides into the groove of the pin sleeve by utilizing the dead weight of the limiting handle, so that the self-locking effect is achieved.

Detailed Description

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1 and 2, the utility model is a propaganda scroll lifting device, comprising a lifting rope 1, a scroll upper supporting device 2, a winding device 5, a guide rope 6, an upper pulley 7, an upper fixing frame 8 and a lower fixing frame 10; the upper fixing frame 8 and the lower fixing frame 10 are both arranged on the wall 9, and a guide rope 6 is arranged between the two ends of the upper fixing frame 8 and the lower fixing frame 10; an upper pulley 7 is arranged on the upper fixing frame 8, and a winding device 5 is arranged on the lower fixing frame 10; a limiting device is arranged on the lower fixing frame 10 and is used for limiting the rotation of the winding device 5; the lifting rope 1 is wound on the winding device 5, the lifting rope 1 is connected to the scroll upper supporting device 2 between the upper fixing frame 8 and the lower fixing frame 10 through the upper pulley 7, and two ends of the scroll upper supporting device 2 slide on the guide rope 6.

As shown in fig. 3, the winding device 5 includes a bearing 51, a handle 54, a rotation shaft 53, and a catch wheel 52, the bearing 51 is installed under the lower mount 10, the rotation shaft 53 is provided on the bearing 51, the rotation shaft 53 passes through the catch wheel 52, and the handle 54 is connected to the rotation shaft 53.

As shown in fig. 4, 16 limiting holes 55 are formed in the periphery of the rotation center of the grooved pulley 52, so that the positions can be easily and effectively adjusted, and limiting can be performed at any time.
