Description

TECHNICAL FIELD

[0001] The adjustable limiting device of the cantilever unloading platform belongs to the technical field of unloading platforms. BACKGROUND

[0002] In building engineering construction, the cantilever unloading platform, as a turnover platform for material transportation inside and outside the building, is widely used in the main construction stage and the decoration stage. Due to the effect of the inwardly inclined steel wire rope on the unloading platform, there is a tendency for the unloading platform to slide inwardly. In order to prevent the unloading platform from sliding inwardly and causing safety hazards, a limiting device is often arranged under the cantilever main beam of the unloading platform, which is abutted against the outer side of the building structure beam to offset the horizontal force generated by the inclined steel wire rope.

[0003] For the limiting mechanism, the most common way is to arrange it at the bottom of the cantilever main beam by welding or other fixing methods. For example, the limiting mechanism is described in the Chinese invention patent with the application number 201910751743.5, the application date of October 25, 2019, the patent name of "unloading platform for high-rise public building construction", the application number of 202210321562.0, the application date of March 30, 2022, the patent name of "unanchored cantilever unloading platform and use method", the application number of 202320573736.2, the application date of March 22, 2023, the patent name of "cantilever unloading platform structure", and the application number of 202322572071.6, the application date of September 20, 2023, the patent name of "unloading platform".

[0004] In the above-mentioned prior art, since the limiting device is fixed integrally with the cantilever main beam, when the building facade structure changes or the length of the cantilever section of the unloading platform needs to be adjusted according to the use requirements, the limiting device needs to be cut off and fixed at the required position again, which is not conducive to the turnover use of the unloading platform, and there are great hidden dangers in the fixing operation.

Although this technical solution realizes the adjustable design of the limiting mechanism, since the position of the abutting piece determines that the worker can only operate from the bottom of the cantilever main beam at the edge of the building structure beam when adjusting the nut, the adjustment process is relatively inconvenient, and there is a certain safety hazard.

DETAILED DESCRIPTION

[0028] Figures 1~6 is the best embodiment of the utility model, and the following will be combined with the drawings to further describe the utility model. Figures 1~6The present invention will be further described below.

[0029] like Figure 1 As shown, an adjustable limiting device for a cantilevered unloading platform includes a limiting frame. A cantilevered main beam 9 supporting the unloading platform is fitted inside the limiting frame. The limiting frame has a side opening, through which the cantilevered main beam 9 is placed. A movable pressure plate 8 is also provided at the side opening of the limiting frame. The movable pressure plate 8 is detachably engaged with the opening of the limiting frame to form a closed loop. A clamping bolt 7 is provided in the middle of the movable pressure plate 8. By rotating the clamping bolt 7 through the rotating handle 6 at the end of the clamping bolt 7, the limiting frame and the cantilevered main beam 9 are fixed. A height-adjustable limiting rod mechanism is provided on the side of the limiting frame. By adjusting the limiting rod mechanism, the rod body of the limiting rod mechanism is made to fit tightly against the outer side of the building structure beam to achieve limiting.

[0030] The limiting frame consists of a web plate 3 and wing plates 10 located at both ends of the web plate 3. The wing plates 10 at both ends are fixed vertically to the same side of the web plate 3, thereby enclosing and forming a space for the limiting frame to accommodate the cantilever main beam 9. The ends of the wing plates 10 at both ends form openings of the limiting frame.

[0031] The limiting rod mechanism is an adjustable support fixed to the side of the web plate 3. The sleeve 4 in the adjustable support is fixed to the side of the web plate 3, and the sleeve 4 and the web plate 3 are arranged parallel to each other. The support screw 5 of the adjustable support passes through the sleeve 4, and the support screw 5 is threadedly connected to the support nut 2 while passing through the sleeve 4. The support nut 2 is rotatably installed at the upper end of the sleeve 4. The relative position of the support screw 5 and the sleeve 4 can be adjusted by rotating the support nut 2. A bracket 1 is provided on the top of the support screw 5. When the support screw 5 moves to the end of the building structural beam, the bracket 1 limits the cantilever main beam 9.

[0032] like Figures 2~3 As shown, the movable pressure plate 8 includes a rectangular pressure plate body 12, with an upper plug 11 formed at the upper end of the pressure plate body 12 and a lower plug 14 formed at the lower end of the pressure plate body 12. The upper plug 11 and the lower plug 14 have the same width, and the vertical depth of the upper plug 11 is greater than the vertical depth of the lower plug 14.

[0033] A pressure plate opening 13 is provided in the middle of the pressure plate body 12. A pressure plate nut 15, concentric with the pressure plate opening 13, is fixed on one side of the pressure plate body 12. The inner hole of the pressure plate nut 15 is smaller than the size of the pressure plate opening 13. The aforementioned clamping bolt 7 passes through the pressure plate opening 13 and is threadedly connected to the pressure plate nut 15, so that the relative position between the clamping bolt 7 and the pressure plate body 12 can be adjusted when the rotating handle 6 is turned.

[0034] like Figure 4As shown, the two wing plates 10 located at the upper and lower ends of the web plate 3 have the same structure, each including a rectangular wing plate body 17. A through wing plate slot 16 is provided at one end of the wing plate body 17, and the end of the wing plate body 17 away from the wing plate slot 16 is fixed to the web plate 3. After the upper and lower wing plates 10 are fixed to the web plate 3, the upper and lower wing plate slots 16 are vertically aligned.

[0035] The specific working process and working principle are as follows:

[0036] like Figures 4~5 As shown ( Figures 4~5 (The limiting rod mechanism is omitted in the middle) The limiting frame, composed of web plate 3 and wing plate 10, is placed inside the cantilever main beam 9 from the side and the limiting frame is positioned at the preset limiting position.

[0037] First, insert the upper plug 11 of the movable pressure plate 8 into the wing plate slot 16 of the upper wing plate 10. Since the depth of the upper plug 11 is greater than the depth of the lower plug 14, when the upper wing plate 10 moves to the root of the upper plug 11, sufficient space is reserved at the bottom of the movable pressure plate 8, allowing the movable pressure plate 8 to enter the inner side of the limiting frame as a whole. Then, insert the lower plug 14 of the movable pressure plate 8 downwards into the wing plate slot 16 of the lower wing plate 10, so that the movable pressure plate 8 and the limiting frame form a closed loop, as shown. Figure 6 The state shown.

[0038] Then, after the clamping bolt 7 passes through the opening 13 of the pressure plate, it is threadedly connected to the pressure plate nut 15. When the rotating handle 6 is turned, the relative position between the clamping bolt 7 and the pressure plate body 12 is adjusted so that the inner end of the clamping bolt 7 abuts against the side of the cantilever main beam 9, and the limiting frame is fixed to the cantilever main beam 9.

[0039] Finally, rotate the support nut 2 to adjust the relative position of the support screw 5 and the sleeve 4. When the support screw 5 moves to the end of the building structure beam, the bracket 1 at the top of the support screw 5 will limit the cantilever main beam 9.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
