[0019] Fig. 3-5 It is a schematic diagram of the local structure of the ladder structure for house construction of the present application. DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the technical scheme of the present application, the present application will be further described in detail below with reference to the drawings and the best embodiment.

[0021] Fig. 1-5A ladder structure for building construction is shown, including a support frame, two side plates 2 mounted on the support frame, and a plurality of detachable, linearly arrayed footplates 3 disposed between the two side plates; the side plates are provided with grooves 8. Fig. 3-4 (As shown in the diagram); sliders 6 that are matched with the grooves are provided on both sides of the pedal 3.

[0022] The slider 3 is provided with a bolt hole, and a positioning component is provided corresponding to the bolt hole. Fig. 5 (As shown). The positioning component includes a pull block 9, a pull rod 10 connected to the pull block, a connecting plate 7 disposed on the pull rod, and a spring 11 disposed between the connecting plate 7 and the pull block 9; both ends of the spring 11 are connected to the connecting plate 7 and the pull block 9 respectively; the pull rod 11 is matched with the bolt hole, the connecting plate 7 is L-shaped, and the pull rod 10 is provided inside the connecting plate 7. The top end of the pull rod 10 passes through the side plate and extends into the bolt hole of the slider 6 to fix the slider 6. The bottom end of the pull rod 10 passes through the bottom of the connecting plate 7 and is fixedly connected to the pull block 9. The pull block 9 makes it convenient for personnel to hold the pull block 9 and pull the pull rod 10 to move, improving the convenience of personnel operation for loading and unloading.

[0023] The inside of the spring 11 is fitted onto the outside of the pull rod 10. The two ends of the spring 11 are fixedly connected to the bottom of the connecting plate 7 and the top of the pull block 9, respectively. With the spring 11, when a person holds the pull block 9 and pulls it downward, the pull rod 10 will move downward. The pull block 9 will then pull the spring 11 downward. At this time, the top of the pull rod 10 will move and separate from the slot in the slider 6, releasing the positioning of the slider 6. The person can then move the pedal 3 to slide the slider 6 out of the slide groove 8 to remove the pedal 3 for maintenance or replacement. During installation, the sliders 6 on both sides of the pedal 3 are aligned with the adjacent slide grooves 8 and slid in. Then, the pull block 9 is released, causing the spring 11 to lose tension and elastically recover, pulling the pull block 9 and the pull rod 10 back to its original position. This allows the top of the pull rod 10 to insert into the slot and position the slider 6, thus fixing the pedal 3 to the side plate 2. This makes it easier for the person to remove the pedal 3, reduces the burden on the person, and improves the practicality of the ladder.

[0024] The bottom of the connecting plate 7 is provided with a limiting groove; a limiting slider 12 is provided in the limiting groove and moves along the limiting groove to allow the plug rod 13 connected to the limiting slider 12 to move closer to or away from the pull block 9; the pull block is provided with a slot that matches the plug rod.

[0025] The bottom side of the connecting plate 7 is provided with a limiting sliding groove, the top side of the pull block 9 is provided with a insertion slot, the bottom of the connecting plate 7 is provided with a limiting sliding block 12 matched with the limiting sliding groove, and the bottom of the limiting sliding block 12 is fixedly connected with an insertion rod 13 matched with the insertion slot. Through the setting of the insertion rod 13 and the insertion slot, when the personnel pull the pull block 9 to move, the limiting sliding block 12 in the limiting sliding groove can be moved to drive the insertion rod 13 to move to the top of the insertion slot of the pull block 9. When the pull block 9 is released, the pull block 9 will reset and make the bottom end of the insertion rod 13 abut in the insertion slot, thereby positioning the pull block 9, so that the pull rod 10 cannot move back to the insertion slot of the sliding block 6, thereby facilitating the personnel to operate the loading and unloading of the sliding block 6 and the pedal 3, without the personnel continuously pulling the pull block 9 by hand, thereby further improving the convenience of the personnel operation loading and unloading.

[0026] Fig. 1-2 The bracket comprises a bottom frame 1 and a vertical bracket connected with the bottom frame; the top of the vertical bracket is provided with a workbench; one side of the side plate is connected with the workbench, and the other side is connected with the bottom frame. As one of the implementation forms, the bracket and the side plate 2 serve as the support basis of the entire structure, and are made of durable aluminum alloy material, which ensures the stability and load-bearing capacity of the ladder stand.

[0027] The bottom of the bottom frame 1 is provided with a lifting component; the lifting component is a pneumatic cylinder 4. The bottom of the pneumatic cylinder is provided with a protective pad. The bottom of the bottom frame is provided with a universal wheel 5. Through the operation of the external controller, the pneumatic cylinder 4 can be extended and retracted freely, thereby driving the lifting of the entire ladder stand. This design not only makes the ladder stand easily adapt to different height operation requirements, but also greatly improves the flexibility and efficiency of operation. At the same time, the bottom of the pneumatic cylinder 4 is also equipped with a protective pad, which not only protects the pneumatic cylinder 4 from being worn by the ground, but also reduces the pressure and damage to the ground during the lifting of the ladder stand.

[0028] The pneumatic cylinder 4 is four, the top of the four pneumatic cylinders 4 is fixedly connected with the bottom of the bottom frame 1 at four corners, and the bottom of the pneumatic cylinder 4 is fixedly connected with a protective pad. One side of the four pneumatic cylinders 4 is provided with a universal wheel 5, and the top of the universal wheel 5 is fixedly connected with the bottom of the bottom frame 1. Through the setting of the pneumatic cylinder 4 and the universal wheel 5, the personnel can control multiple pneumatic cylinders 4 to lift at the same time through the external controller, so that multiple universal wheels 5 are in contact with the ground, which can conveniently move the ladder stand to different working areas of the house, and by controlling multiple pneumatic cylinders 4 to descend at the same time, the protective pad is in contact with the ground, so that the entire ladder stand is lifted, which is convenient for the personnel to work at different heights of the house. Through the setting of the protective pad, the protective pad can provide protection for the pneumatic cylinder 4, avoiding the direct contact of the bottom end of the pneumatic cylinder 4 with the ground, which causes wear.

[0029] The use principle of the utility model is: when needing to maintain or replace the pedal 3, the operator first holds the pull block 9 by hand and exerts force downward, which directly drives the pull rod 10 to move downward along its axial direction. The outside of the pull rod 10 is sleeved with the inside of the spring 11, so that in the process of the pull rod 10 moving downward, the spring 11 is stretched, and its two ends are fixed at the bottom of the connecting plate 7 and the top of the pull block 9 respectively, thereby ensuring the stability of the spring 11 in the stretching process. With the downward movement of the pull rod 10, its top end gradually separates from the slot in the slider 6, which changes the locking state of the slider 6, so that the slider 6 can freely slide in the sliding groove 8. At this time, the operator can easily move the pedal 3 to make the slider 6 slide out along the path of the sliding groove 8, realize the separation of the pedal 3 and the side plate 2, and provide convenience for subsequent maintenance or replacement. When installing the pedal 3, the operation process is also simple. First, align the sliders 6 on both sides of the pedal 3 with the adjacent sliding grooves 8, and then gently push in to make the sliders 6 slide along the path of the sliding grooves 8 to the predetermined position. Then, release the pull block 9, at this time the spring 11 loses the external pulling force and starts to exert its elastic recovery effect, pulling the pull block 9 and the pull rod 10 upward. When the top end of the pull rod 10 reinserts into the slot in the slider 6, the slider 6 is locked again, thereby ensuring the stable connection between the pedal 3 and the side plate 2, realizing the quick disassembly and assembly function of the pedal 3, and greatly improving the convenience of the operator. Without the need to use complex tools or additional auxiliary equipment, the practicability of the ladder is improved.

[0030] When the operator needs to disassemble the pedal 3, first hold the pull block 9 and pull it downward, which drives the pull rod 10 to move downward, and the limit slider 12 fixedly connected with the top of the pull block 9 slides in the limit slot. With the downward movement of the pull block 9, the limit slider 12 drives the insertion rod 13 to gradually move away from the pull block 9, preparing for the subsequent return of the pull block 9 and the insertion of the insertion rod 13 into the slot.

[0031] When the top end of the pull rod 10 completely separates from the slot in the slider 6, the operator can release the pull block 9. At this time, due to the elastic recovery effect of the spring 11, the pull block 9 starts to return upward. In the process of returning, the slot is aligned with the insertion rod 13, until the bottom end of the insertion rod 13 completely inserts into the slot, realizing the positioning of the pull block 9. At this time, due to the locking effect of the insertion rod 13 on the pull block 9, the pull rod 10 is kept at the current position and cannot automatically return and insert into the slot in the slider 6. This design allows the operator to free his hands and focus on moving the pedal 3 and the slider 6 to complete the disassembly of the pedal 3, so that the operator does not need to continuously pull the pull block 9 with his hand when disassembling the pedal 3, thereby freeing his hands to focus on other operations, such as moving the pedal 3 and the slider 6, etc. This design greatly improves the flexibility and efficiency of the operation.

[0032] The above merely describes preferred embodiments of the present application, and for those skilled in the art, according to the idea of the present application, changes can be made in the specific implementation manner and application range, and the content of the specification should not be understood as a limitation of the present application.
