TECHNICAL FIELD

[0001] The present application belongs to the technical field of building construction, and particularly relates to an adjustable assembly type guide frame base of an electric lifting construction platform for facade construction. BACKGROUND

[0002] The electric lifting construction platform is applied to the facade decoration of curtain walls, coatings and masonry in the building industry, and can also be used for other types of aerial work, such as facade renovation and curtain wall cleaning. The use of the electric lifting construction platform has the following advantages: 1. Good economic performance: regardless of the height of the building, the electric construction lifting platform only needs to set up one (or two) column and a liftable operation platform along the building, which can save a large amount of steel; 2. Good safety performance: the electric construction lifting platform is a lifting machine driven by gear and rack, and a fall arrestor is arranged on the electric construction platform, which can brake in an emergency when falling occurs to prevent major accidents such as operation platform falling. 3. Easy to install, use and disassemble, high efficiency: the electric construction lifting platform only needs to set up one or two columns and a liftable operation platform along the building during installation, which can be used for work, without having to arrange several layers of walkway plates around the building like a full steel frame.

[0003] The base of the traditional electric lifting construction platform needs to fix the legs of the base on the four corners of the load-bearing frame during use. In this case, the length of the legs cannot be adjusted, the distance from the leg action point to the center of the base is a fixed value, and the area enclosed by the connecting line of the leg action points is also a fixed value, which is not conducive to the anti-overturning ability of the electric lifting construction platform under the condition of excessive vertical load or excessive horizontal load, and is not conducive to the stability of the electric lifting construction platform.

The connecting structure comprises plug-in holes arranged at both ends of the first fixed column 1 and modular holes arranged on the plug rod 4. The plug-in holes and the modular holes are fixedly connected by connecting bolts. According to the vertical load borne by the guide frame base, the extension length of the supporting leg relative to the receiving cavity is adjusted, thereby adjusting the area enclosed by the connecting line of the action points of the supporting legs, and further increasing the anti-overturning capacity of the guide frame base.

[0041] In this embodiment, the guide frame base further comprises four movable frames. The movable frames are detachably connected to the fixed frame. The movable frame comprises a connecting plate 9, a horizontally arranged connecting rod 10 fixedly connected to the connecting plate 9, and a supporting column foot 11 fixedly connected perpendicularly to the connecting rod 10. The connecting rod 10 is fixedly connected perpendicularly to the connecting plate 9. The supporting column foot 11 is fixed to an end of the connecting rod 10 away from the connecting plate 9. The supporting column foot 11 is fixedly connected perpendicularly to the connecting rod 10. Two connecting rods 10 of the movable frame are spaced apart in the extension direction of the connecting plate 9. The supporting column foot 11 is arranged correspondingly to the connecting rod 10. In this embodiment, the length of the supporting column foot 11 in the up-down direction is adjustable. The supporting column foot 11 is a telescopic hydraulic cylinder.

[0042] The first horizontal column 2 is provided with a guide groove 8 extending in the left-right direction at both ends. The first vertical column 3 is provided with a guide groove 8 extending in the front-rear direction at both ends. A telescopic rod 12 is correspondingly arranged on the connecting rod 10 of the movable frame. The telescopic rod 12 extends in the up-down direction and is parallel to the supporting column foot 11. The length of the telescopic rod 12 in the up-down direction is adjustable. A guide block 13 is arranged at the lower end of the telescopic rod 12 and is guided and fitted in the guide groove 8.

[0043] In the embodiment, the guide groove 8 comprises a guide cavity 14 and a communication groove 15 which communicates the guide cavity 14 with the outside, the communication groove 15 is arranged above the guide cavity 14, the communication groove 15 is located in the middle of the guide cavity 14 and coincides with the central axis of the guide cavity 14. The upper surface of the guide cavity 14 comprises inclined surfaces 16 which are symmetrically arranged on both sides of the communication groove 15, the inclined surfaces 16 are arranged from both sides of the guide cavity 14 to the central axis and from top to bottom, the guide block 13 at the lower end of the telescopic rod 12 is matched with the shape of the guide cavity 14 of the guide groove 8, and the communication groove 15 avoids the telescopic rod 12. The structure of the guide groove 8 and the guide block 13 can prevent the guide block 13 from escaping from the guide groove 8.

[0044] The outer side of the rectangular frame is fixed with a reinforcing column 6, four reinforcing columns 6 are arranged, the reinforcing column 6 is arranged in the same direction as the first fixed column 1 and is fixedly connected with the first fixed column 1.

[0045] The fixed frame is fixed with a plurality of connecting seats which are fixedly connected with the column steel pipe, the connecting seat comprises an inverted U-shaped connecting plate 9 which is fixedly connected with the first cross column 2 or the first longitudinal column 3, the connecting plate 9 is fixed with a plug-in sleeve, the column steel pipe is plug-in matched with the plug-in sleeve, and a reinforcing rib is fixed between the plug-in sleeve and the connecting plate 9.

[0046] In the embodiment, the movable frame comprises a first working position and a second working position. When the movable frame is located at the first working position, the supporting column foot 11 is fixed on the fixed frame, the connecting plate 9 surrounds a rectangular frame which fixes the column of the electric lifting construction platform, at this time, the guide block 13 at the lower end of the telescopic rod 12 on the movable frame is located in the guide groove 8, thereby ensuring that the movable frame is stably fixed above the fixed frame, and the rectangular frame surrounded by the connecting plate 9 is fixedly connected with the column of the electric lifting construction platform. In this way, the four movable frames surround and fix the column of the electric lifting construction platform above the fixed frame, thereby further increasing the connection stability between the column of the electric lifting construction platform and the fixed frame. When the electric lifting construction platform bears a large lateral load, the connection form between the column, the fixed frame and the movable frame increases the connection strength between the column and the fixed frame, thereby enabling the electric lifting construction platform to bear a large lateral load.

[0047] When the movable frame is in the second working position, the telescopic rods 12 of the movable frame move outward along the guide grooves 8 until the connecting plates 9 of the movable frame move into the mounting grooves 7 of the reinforcing columns 6, at this time, the support column feet 11 of the movable frame are fixed on the bearing frame, the lower ends of the telescopic rods 12 of the movable frame are fixed on the bearing frame, and the connecting plates 9 of the movable frame are fixedly connected with the reinforcing columns 6, which not only increases the support area of the guide frame base, but also increases the number of support points of the guide frame base on the bearing frame, so that when the electric lifting construction platform receives a larger vertical load, the fixed frame and the movable frame fixed relative to the fixed frame at the same height can bear a larger vertical load of the guide frame base. Therefore, the guide frame base including the fixed frame and the movable frame of the present application can provide stable support for the stand column whether the electric lifting construction platform bears a larger lateral load or a larger vertical load, thereby avoiding the side inclination of the electric lifting construction platform, and ensuring the safety of the electric lifting construction platform in use.
