Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a self-elevating scaffold for building construction with a telescopic platform. Background Art

[0002] The building construction scaffold is an important construction tool in building construction projects. Its main function is to provide a working platform and safety protection for construction workers. With the development of technology, some scaffolds have the function of automatic lifting.

[0003] In the prior art, such as the utility model with the publication number CN208844886U, this utility model discloses an automatic lifting scaffold, which includes a box body. The bottom of the inner wall of the box body is fixedly connected with a lifting motor through a motor base. A rotating disc is fixedly connected to the output shaft of the lifting motor. Guide pulleys are fixedly connected to both sides of the top of the inner wall of the box body. Limit rods are fixedly connected to the bottom of both sides of the inner wall of the box body. One end of the limit rod is fixedly connected with a limit frame. Pulling ropes are fixedly connected to both sides of the surface of the rotating disc. One end of the pulling rope is fixedly connected with a moving block through a pulling block. A connecting block is fixedly connected to one side of the moving block. This utility model relates to the technical field of scaffolds. This automatic lifting scaffold solves the problems that it is time-consuming and laborious to manually build a scaffold, and it is not easy to fix the scaffold after it is lifted. It effectively improves the stability of the scaffold during operation, greatly reduces the working intensity of the staff, and has a simple structure, which is convenient for the staff to operate. It solves the problem that the traditional scaffold is often manually built layer by layer when it needs to be lifted. This method is not only time-consuming and laborious, but also not conducive to improving work efficiency. Some advanced enterprises use electric lifting scaffolds, but the scaffolds are often not easy to fix after being lifted, which is not conducive to the safe operation of the staff.

[0004] In daily work, it is found that when the existing self-elevating scaffold for building construction is in use, due to the fixed size of the platform of the self-elevating scaffold, the operating space of the construction workers is fixed and limited. The narrow working platform may cause overcrowding of the construction workers, increasing the risks of collision and falling, which is not conducive to the simultaneous operation of multiple people and the placement of large tools and materials, resulting in frequent up and down transportation of materials and reducing the construction efficiency. Furthermore, it leads to the limited platform space of the existing self-elevating scaffold for building construction, affecting the construction. Summary of the Utility Model

[0005] The purpose of this utility model is to solve the drawback that the platform space of the existing self-elevating scaffold for building construction is limited and affects construction, and to propose a self-elevating scaffold for building construction with a telescopic platform.

[0006] To achieve the above object, the utility model adopts the following technical solution: a self-elevating scaffold for building construction with a telescopic platform, comprising a frame body and an adjusting device. A winch is installed on the lower surface of the frame body, and multiple groups of hanging wheels are installed on the surface of the frame body. Two lifting ropes are installed in the winch, and the lifting ropes bypass the hanging wheels and are fixedly connected to the surface of a moving frame.

[0008] Preferably, the two limiting holes on the surface of the limiting rod are respectively arranged on the surfaces near both ends of the limiting rod. Through the above components, the two limiting holes can be used to position the sliding plate and the slider when they are expanded or retracted.

[0009] Preferably, the supporting component includes iron frames, and the number of the iron frames is four. The four iron frames are respectively fixedly connected to the two side surfaces of the frame body. Multiple supporting grooves are formed on the surfaces of the iron frames.

[0010] Preferably, a rotating handle is rotatably connected to the inner wall of the concave block, and one end of the rotating handle is fixedly connected to the surface of the supporting block.

Two lifting ropes 6 are installed in the hoist 2, and the lifting ropes 6 bypass the hanging wheels 5 and are fixedly connected to the surface of the moving frame 3. A platform body 4 is arranged between the two moving frames 3, and the adjusting device 7 is arranged on the surface of the platform body 4.

[0022] Specifically, the adjusting device 7 includes sliding plates 71. The number of sliding plates 71 is two, and the two sliding plates 71 are arranged below the platform body 4. Two sliders 73 are fixedly connected to the surface of the sliding plates 71. Four sliding holes 72 are formed on the surface of the platform body 4, and the sliders 73 are slidably connected to the inner walls of the sliding holes 72. A positioning component 74 is arranged between the sliders 73 and the inner walls of the sliding holes 72, and a support component 75 is arranged between the sliding plates 71 and the frame body 1.

[0023] In this embodiment: by sliding the sliders 73 back and forth in the sliding holes 72 of the platform body 4, the sliding plates 71 can be driven to expand and contract, thereby expanding the usage range of the platform body 4.

[0024] Specifically, the positioning component 74 includes a screw rod 741, and the screw rod 741 is threadedly connected to the inner wall of the slider 73. Two limiting rods 742 are fixedly connected to the inner wall of the sliding hole 72. The number of limiting rods 742 is two. Two limiting holes are formed on the surface of the limiting rods 742, and the screw rod 741 is inserted into the inner walls of the limiting holes. When it is necessary to position the sliders 73 and the sliding plates 71, just insert the screw rod 741 into the limiting holes on the surface of the limiting rods 742 to complete the positioning.

[0025] Specifically, the two limiting holes on the surface of the limiting rod 742 are respectively arranged on the surfaces near the two ends of the limiting rod 742. The two limiting holes can be used to position the sliding plates 71 and the sliders 73 when they are expanded or retracted.

[0026] Specifically, the support component 75 includes iron frames 755. The number of iron frames 755 is four, and the four iron frames 755 are respectively fixedly connected to the two side surfaces of the frame body 1. Multiple support grooves are formed on the surfaces of the iron frames 755. Concave blocks 751 are respectively fixedly connected to the two sides of the sliding plates 71. The inner walls of the concave blocks 751 are concave, and the concave blocks 751 are inserted into the inner walls of the support grooves on the surfaces of the iron frames 755.

[0027] In this embodiment: when the sliding plates 71 are extended and unfolded, the support blocks 753 can be rotated, and the support blocks 753 can be inserted into the support grooves on the surfaces of the iron frames 755, thereby supporting and strengthening the sliding plates 71 and improving the stability effect.

[0028] Specifically, a rotating handle 752 is rotatably connected to the inner wall of the concave block 751.

[0031] Working principle: When in use, the winch 2 can be turned on. The winch 2 winds and collects the lifting rope 6. The lifting rope 6 drives the moving frame 3 and the platform body 4 to move upward through the lifting pulley 5. When it is necessary to expand the range of the platform body 4, the screw rod 741 is rotated. After the screw rod 741 loses the restraint on one of the limiting holes on the surface of the limiting rod 742, the sliding plate 71 can be driven to move through the slider 73, so that the sliding plate 71 extends out from the bottom of the platform body 4, thereby expanding the moving range of the platform body 4. Subsequently, the screw rod 741 is rotated again. The screw rod 741 can be inserted into another limiting hole on the surface of the limiting rod 742. At the same time, the knob handle can be rotated. The knob handle can drive the support block 753 to rotate, so that the support block 753 rotates into the support groove on the surface of the frame body 1. The magnetic ring 754 on the surface of the support block 753 can be attracted to the frame body 1, thereby strengthening the sliding plate 71.
