Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] It should be noted that the following detailed descriptions are exemplary and intended to provide further explanation of this application. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0025] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0026] like Figures 1-7 As shown, a film roll hoisting connection structure includes a vertically arranged main sleeve 1. Several arc-shaped tensioning components 2 are evenly distributed around the outer circumference of the main sleeve, sliding radially along the main sleeve. A drive rod mechanism 3 is slidably connected inside the main sleeve to drive each arc-shaped tensioning component to slide outwards. An inward retraction component 4 is fitted outside the tensioning sleeve composed of each arc-shaped tensioning component to drive each component to reset inwards. In use, the entire device is first inserted into the mandrel of the film roll, and then the drive rod mechanism is pulled out, causing the arc-shaped tensioning components to... The components expand outwards and press against the inner wall of the mandrel roll. Because the crane hook is constantly pulling the drive rod mechanism during the crane lifting process, the arc-shaped tensioning components are always in a state of expanding outwards and pressing against the inner wall of the mandrel roll. When the film roll is moved to the required position, the crane hook disengages from the drive rod mechanism. At this time, the drive rod mechanism is pushed into the main sleeve, and each arc-shaped tensioning component retracts under the action of the inward shrinking component, so that the arc-shaped tensioning components disengage from the inner wall of the mandrel roll, the whole device is disengaged, and the film roll is moved.

[0027] In the embodiment, in order to realize the driving rod mechanism to drive the arc-shaped expansion assembly to expand outward, the arc-shaped expansion assembly comprises arc-shaped plates 5, the curved surface radius of each arc-shaped plate is the same, and each arc-shaped plate can jointly form an expansion sleeve, and the arc-shaped plates in the embodiment are arc-shaped plates with a central angle of 90°. At least one expansion wedge 6 is fixed on the inner arc surface of each arc-shaped plate from top to bottom. The device adopts two expansion wedges which are distributed from top to bottom. The driving rod mechanism comprises a driving rod 7 arranged vertically. A conical surface 8 is arranged on the lower part of the driving rod and spaced apart from each other corresponding to the two expansion wedges. The inner wall surface of the expansion wedge is slidably connected to the conical surface. A plurality of displacement expansion holes 9 are formed on the outer wall of the main sleeve for the sliding of the expansion wedge. When in use, the displacement expansion hole limits the sliding direction of the expansion wedge, so that the expansion wedge can only move radially to the main sleeve. When the driving rod is pulled upward, the driving rod drives the conical surface to move upward. At this time, the expansion wedge is expanded outward under the action of the conical surface.

[0028] In the embodiment, in order to realize the expansion wedge to expand outward under the action of the conical surface, the small circle of the conical surface is on the top and the large circle is on the bottom. The inner wall surface of the expansion wedge is an inclined curved surface 10 arranged corresponding to the conical surface, that is, the inclined curved surface is inclined upward to the center of the driving rod. When the conical surface rises, the large circle end of the conical surface gradually rises due to the limitation of the displacement expansion hole to the sliding direction of the expansion wedge, so that the expansion wedge expands outward. The outer wall surface of the expansion wedge is a vertical curved surface 11 arranged corresponding to the inner wall surface of the arc-shaped plate. The vertical curved surface is arranged to facilitate the installation of the expansion wedge and the arc-shaped plate. The installation mode can be screwing.

[0029] In the embodiment, in order to realize the sliding of the driving rod in the main sleeve, an annular shoulder 12 is arranged on the lower part of the driving rod outside the large circle of the conical surface. The outer diameter of the annular shoulder is the same as the outer diameter of the large circle of the conical surface. The upper end surface of the annular shoulder is fixedly connected to the end surface of the large circle of the conical surface. The annular shoulder is slidably connected to the main sleeve, that is, the outer diameter of the annular shoulder matches the inner diameter of the main sleeve, so as to realize the sliding of the driving rod in the main sleeve.

[0030] In the embodiment, in order to realize that when the driving rod descends and the conical surface does not expand the arc-shaped plate, each arc-shaped plate can be retracted, the inner retraction assembly is a ring-shaped spring 13. At least one horizontal arc-shaped groove 14 is arranged on the outer wall surface of the arc-shaped plate. The arc-shaped grooves corresponding to each arc-shaped plate form a ring-shaped containing groove 15 for containing the ring-shaped spring. Two arc-shaped grooves are arranged on the outer wall surface of the arc-shaped plate in the embodiment, that is, two ring-shaped containing grooves are arranged symmetrically on the outer wall surface of the arc-shaped plate from top to bottom. The springs contained in the upper and lower ring-shaped containing grooves can bind the upper and lower ends of the arc-shaped plate. When the conical surface does not expand the arc-shaped plate, each arc-shaped plate can be retracted under the action of the spring and the limitation of the displacement expansion hole to the expansion wedge.

[0031] In the embodiment, in order to design reasonably, the upper and lower ends of the main sleeve are provided with sleeve flanges 16, each arc-shaped plate is slidably connected between the two sleeve flanges, the lower end of the main sleeve is connected with a closed bottom plate 17 through the sleeve flange, for closing the lower end of the main sleeve, the upper end of the main sleeve is connected with a sliding sleeve 18 through the sleeve flange and bolts, the sliding sleeve can be provided with a sliding flange 19 at one end matched with the sleeve flange of the upper end of the main sleeve, the sliding flange is bolted between the sleeve flanges, to realize the fixed connection between the sliding sleeve and the main sleeve, the upper part of the driving rod is slidably connected in the sliding sleeve and extends upwardly out of the sliding sleeve, in use, only the sliding sleeve needs to be held by hand, and then the driving rod is pulled out, to realize the expansion operation.

[0032] In the embodiment, in order to facilitate the connection of the driving rod and the driving rod, the upper end of the driving rod is connected with a pull ring 20 matched with the driving hook.

[0033] In the embodiment, in order to design reasonably, the outer wall surface of the arc-shaped plate is a corrugated surface 21 except the arc-shaped groove area.
