DETAILED DESCRIPTION
[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0038] Reference Figures 1 to 3 The utility model provides an embodiment: a cold-bent steel for a high-altitude cantilever construction platform, including a wall 1 and two slide rails 3. The wall 1 is the main supporting structure of the platform, which is generally completed by concrete pouring and has good fixation. A plurality of U-shaped steels 2 are fixedly connected to the top of the wall 1. The U-shaped steel 2 is a steel structure. The embedded steel plate is pre-embedded in advance during concrete pouring. After the slide rail 3 is placed in position, the U-shaped steel 2 is fixed to the embedded plate by welding. A fixed block 11 is fixedly connected to the top of the wall 1 for supporting subsequent drive components. An electric push rod 10 is fixedly connected to the right side of the fixed block 11. The electric push rod 10 is used to provide power for the subsequent sliding components. The driving end of the electric push rod 10 is fixedly connected to a connecting rod 9. The connecting rod 9 is used to connect two independent sliding structures to make them a whole and slide synchronously. Two sleeve rods 4 are fixedly connected to the right side of the wall 1. The interior of the sleeve rod 4 adopts a hollow design to facilitate the internal space for sliding and extension. The interior of the sleeve rod 4 is slidably connected to a support rod 5, which directly supports the bottom of the hanging box 12 to reduce the risk of bottom collapse due to excessive weight of goods. The interior of the support rod 5 is fixedly connected to a fixed column 6, which serves as a sliding limit structure and can be fixed inside the empty slot 7 for sliding limit. Two empty slots 7 are provided inside the two sleeve rods 4, and the empty slot 7 is used to limit the sliding of the support rod 5. Two sliding blocks 8 are respectively slidably connected to the interiors of the two slide rails 3, and the tops of the two sliding blocks 8 are fixedly connected to the hanging box 12. The sliding blocks 8 and the hanging box 12 are fixed as a whole, and the sliding of the hanging box 12 is driven by the sliding blocks 8. A rotating structure is provided inside the hanging box 12 for adjusting the state of internal components.
[0039] Reference Figure 3 , Figure 4 and Figure 5The rotating structure includes a rotating shaft 14, both ends of which are rotatably connected to the interior of the hanging material box 12, and the rotation of the rotating shaft 14 drives the subsequent components to rotate to achieve the use function. A baffle 13 is fixedly connected to the outside of the rotating shaft 14, and the baffle 13 is used to protect the internal materials to prevent the risk of falling. A rubber pad 16 is fixedly connected to the left side of the baffle 13, and the rubber pad 16 can provide a buffering force when the baffle 13 is placed on the ground to protect the baffle 13. A plurality of anti-skid teeth 19 are fixedly connected to the right side of the baffle 13, and the anti-skid teeth 19 can increase the friction force of the transport vehicle during transportation and generate a certain limiting resistance. A card slot 15 is provided on the front side of the baffle 13, and a card rod 17 is slidably connected to the inside of the card slot 15. The outside of the card rod 17 is slidably connected to the inside of the hanging material box 12, and a spring 18 is sleeved on the outside of the card rod 17. The spring 18 is used to provide a reaction force to rebound the card rod 17 so that it is engaged with the inside of the baffle 13.
[0040] Reference Figure 1 and Figure 2 The front and rear ends of the connecting rod 9 are respectively fixedly connected to the adjacent sides of the two sliders 8. The connecting rod 9 and the slider 8 are connected to form a whole. The movement of the connecting rod 9 then drives the slider 8 to slide. The tops of the two slide rails 3 are in contact with the interiors of the multiple U-shaped steels 2 respectively. Through the top of the slide rail 3 in contact with the interior of the U-shaped steel 2, one end of the slide rail 3 is subjected to the pressure of the U-shaped steel 2 and is thus fixed. The outsides of the two fixed columns 6 are slidably connected to the insides of the two empty grooves 7. Through the sliding of the fixed columns 6 in the empty grooves 7, subsequent sliding limiting can be achieved to achieve a supporting effect. The bottoms of the two slide rails 3 are in contact with the top of the wall 1, providing a certain supporting force for the slide rail 3 and providing corresponding stability for the construction platform.
[0041] Reference Figure 3 and Figure 4 One end of the spring 18 is fixedly connected to the front side of the hanging box 12, and the other end of the spring 18 is fixedly connected to the outside of the clamping rod 17. Through the fixed connection at both ends of the spring 18, not only can the clamping rod 17 be prevented from sliding too much and falling off, but a reaction force can also be generated to facilitate the clamping of the clamping rod 17.
[0042] Reference Figure 6 and Figure 7The interior of the material hanging box 12 is fixedly connected to a fixed shaft 20 for providing a rotation point for the subsequent rotating components. The exterior of the fixed shaft 20 is rotatably connected to a lever 21, and the two sections of the structure are connected by the lever 21 to cause reverse movement. The left side of the lever 21 is rotatably connected to a pedal button 23, which can be directly triggered by the foot and is relatively portable. The right side of the lever 21 is rotatably connected to a limit plate 22, and the wheels of the transport vehicle are limited by the lifting of the limit plate 22 to prevent the wheels from moving due to inertia when the material hanging box 12 slides, colliding with the interior of the material hanging box 12 and causing damage. The exterior of the pedal button 23 is slidably connected to the interior of the material hanging box 12, and the exterior of the limit plate 22 is slidably connected to the interior of the material hanging box 12. The sliding of the pedal button 23 and the limit plate 22 can allow the pedal button 23 to slide out when needed to limit the wheels of the transport vehicle.
[0043] Working principle: First, install the construction platform inside the U-shaped steel 2, fix the slide rail 3 by the downward fixing force of the U-shaped steel 2, then pull the clamping rod 17 to the rear side, and separate it from the clamping groove 15 after the clamping rod 17 slides inside the clamping groove 15, and then rotate the rotating shaft 14 to place one end of the baffle 13 on the top of the wall 1, and use the rubber pad 16 to buffer to prevent excessive vibration, and then use the transportation equipment to push the material from the top of the baffle 13 to the inside of the hanging box 12 to complete the loading of the material, and then pull the clamping rod 17 to rotate the baffle 13 to match the clamping groove 15 with the clamping rod 17, release the clamping rod 17, and clamp the clamping rod 17 to the baffle through the reaction force of the spring 18. The baffle plate 13 is installed inside the plate 13 to complete the fixation. The problem that the height of the hanging material box 12 and the wall 1 is different in actual situation and it is inconvenient for the transportation tool to transport materials is solved by adding the baffle plate 13, which improves the portability and can also shield the loaded materials to prevent them from falling before lifting and causing safety accidents, thereby improving safety. Then, the wheels of the transportation tool are transported to the right side of the limit plate 22, and the pedal button 23 is pressed to drive one end of the lever 21 to move downward and rotate around the fixed axis 20, and the other end drives the limit plate 22 to slide out, limiting the wheels to prevent the transportation tool from colliding with the inside of the hanging material box 12 due to the inertia generated when the hanging material box 12 slides, causing damage, thereby improving the service life of the hanging material box 12.
[0044] Secondly, after loading the goods, turn on the switch of the electric push rod 10, extend the driving end of the electric push rod 10, drive the connecting rod 9 to move to the right, and then drive the two sliding blocks 8 to slide to the right on the two slide rails 3, and further drive the material box 12 to slide to the right as a whole. At this time, one end of the support rod 5 rotatably connected at the bottom is also driven to move to the right, driving the sleeve rod 4 to rotate, and the fixed column 6 outside the support rod 5 slides to the limit groove at the top of the empty groove 7 to complete the fixation, and supports the material box 12. By adding a sliding support device, workers are prevented from frequently getting on and off the material box 12 to load and unload goods, causing safety accidents of falling goods, reducing safety hazards, and the support device at the bottom can support the material box 12 to prevent collapse, thereby further improving safety.
[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
