Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, specifically relating to a scaffolding suitable for complex terrain. Background Technology

[0002] In numerous fields such as construction, decoration, and equipment installation, scaffolding serves as a crucial tool for providing a working platform for construction workers and ensuring the smooth progress of construction; its importance is self-evident. Traditional scaffolding comes in a variety of types, which can be categorized by material (wooden scaffolding, bamboo scaffolding, steel pipe scaffolding, etc.), by location (external scaffolding and internal scaffolding), and by structural form (pole-type scaffolding, bridge-type scaffolding, frame scaffolding, suspended scaffolding, etc.).

[0003] When faced with complex terrain such as stairwells, conventional scaffolding reveals numerous insurmountable problems. Stairwells typically have complex geometries, with specific variations in slope, step height, and width, and are relatively narrow, often arranged in a circular or zigzag pattern. Conventional scaffolding treads are often designed for horizontal, regular planes, making it difficult to directly adapt to the incline and variations of stairwells. When erecting conventional scaffolding on stairwells, it is difficult to find stable support points, resulting in unstable tread placement. The uprights and horizontal bars of conventional scaffolding are mostly of standard length, lacking flexible adjustment mechanisms for the specific slope and height of stairwells. This prevents precise adjustment of tread height and angle, causing treads to not fit snugly against the steps after installation, leading to wobbling and tilting. This not only causes significant inconvenience for construction workers but also poses serious safety hazards. Utility Model Content

[0004] The purpose of this invention is to provide a scaffolding design suitable for complex terrain, addressing the problem that conventional scaffolding treads are often designed for horizontal, regular planes, making it difficult to directly adapt to the incline and variations of stairwells. When erecting conventional scaffolding on stairwells, it is difficult to find stable support points, making it difficult to install treads stably. Conventional scaffolding uprights and horizontal bars are mostly of standard length, lacking flexible adjustment mechanisms for the special slopes and heights of stairwells. This prevents precise adjustment of tread height and angle, causing treads to not fit tightly against the stair steps after installation, leading to wobbling and tilting. This not only causes great inconvenience to construction workers but also poses serious safety hazards.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a scaffold suitable for complex terrain, comprising vertical poles, four vertical poles in pairs, each of the four vertical poles being movably fitted with a sleeve post, a footboard welded between the sleeve posts, a transmission plate welded between the two sleeve posts of each pair of vertical poles, and a bearing welded to the bottom of the center end of the transmission plate;

[0006] The bottom inner ring of the bearing is welded to the top of the screw. The screw has a thread that penetrates the inside of the threaded post on its outer wall near the bottom. The threaded post is welded to the inside of the fixing plate. The two ends of the fixing plate are respectively welded and sleeved between the two vertical rods of each group. A connecting frame is welded to the bottom of each group of vertical rods.

[0007] In order to adjust the height of one side of the pedal, as a scaffold suitable for complex terrain according to this utility model, preferably, two guide rods are symmetrically welded to the bottom of each transmission plate. The outer walls of the two guide rods are respectively interference-fitted into the reinforcing plate. The bottom of the guide rods movably passes through both sides of the fixed plate. The reinforcing plate is arranged parallel between the transmission plate and the fixed plate.

[0008] In order to enable the threaded telescopic rod to be tilted and supported between two connecting frames when the scaffolding is used in a scene with height difference, as a scaffolding suitable for complex terrain, the preferred embodiment of this utility model is that a fixed sleeve is fixedly sleeved at the center end of each of the two connecting frames, a movable sleeve is movably sleeved on the outer wall of the fixed sleeve, and a threaded telescopic rod is connected between the two movable sleeves, with the two ends of the threaded telescopic rod being movably inserted into the corresponding movable sleeve.

[0009] Two positioning elements are symmetrically welded to the inner wall of the annular recess of the fixed sleeve. Each positioning element is movably installed in a corresponding rotating groove. The rotating groove is opened on the inner wall of the movable sleeve. The side of the rotating groove has a C-shaped structure. The inner wall of the movable sleeve is in movable contact with the inner wall of the annular recess of the fixed sleeve. The maximum rotation angle of the movable sleeve on the fixed sleeve is 240°.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] When scaffolding is needed in complex terrain such as staircases, the height of the screw placed at a high position can be adjusted downwards. As the screw moves downwards, it will cause the height of the transmission plate to adjust downwards as well. When the transmission plate moves downwards, the support of the two corresponding sleeves will be released, and the corresponding sleeves will move downwards. As the sleeves move downwards, they will cause the corresponding side of the tread to move downwards. When the tread is in a horizontal state, the adjustment of the screw will stop.

[0012] Next, insert one end of the threaded telescopic rod into the outer wall of one of the movable sleeves, and then adjust the threaded telescopic rod to move closer to the other movable sleeve. When the threaded telescopic rod is also inserted into the other movable sleeve, adjust the threaded telescopic rod slightly to make it firmly supported between the two movable sleeves.

[0013] In summary, with the combination of the above structures, the scaffolding can maintain a stable and safe operating condition in complex terrains such as stairwells. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides the following technical solution: a scaffold suitable for complex terrain, including vertical poles 1, four vertical poles 1 in pairs, each of the four vertical poles 1 is movably sleeved with a sleeve post 2, a footboard 3 is welded between the sleeve posts 2, a transmission plate 4 is welded between the two sleeve posts 2 of each group of vertical poles 1, and a bearing 5 is welded to the bottom of the center end of the transmission plate 4.

[0023] The vertical pole 1, the sleeve column 2, and the platform 3 are assembled to form a scaffold. When in use, workers can stand on the platform 3 to carry out construction at heights.

[0024] The bottom inner ring of bearing 5 is welded to the top of screw 6. The screw 6 has a thread that passes through the inside of threaded post 7 on the outer wall near the bottom. The threaded post 7 is welded through the inside of fixed plate 8. The two ends of fixed plate 8 are respectively welded and sleeved between the two vertical rods 1 of each group. A connecting frame 9 is welded near the bottom of each group of vertical rods 1.

[0025] Preferably, each transmission plate 4 has two guide rods 41 symmetrically welded to its bottom. The outer walls of the two guide rods 41 are respectively interference-fitted into the reinforcing plate 42. The bottom of the guide rods 41 movably passes through both sides of the fixed plate 8. The reinforcing plate 42 is arranged parallel between the transmission plate 4 and the fixed plate 8.

[0026] In actual use, when the transmission plate 4 moves downward, it will drive the guide rod 41 to move. When the guide rod 41 moves downward, it will pass through the fixed plate 8 and move downward, which can improve the stability of the structure when it moves.

[0027] The screw 6 moves through the reinforcing plate 42 and connects with the bearing 5. When in use, the reinforcing plate 42 can enhance the stability of the two guide rods 41.

[0028] Preferably: a fixed sleeve 91 is fixedly sleeved at the center end of each of the two connecting frames 9, a movable sleeve 94 is movably sleeved on the outer wall of the fixed sleeve 91, and a threaded telescopic rod 95 is connected between the two movable sleeves 94, with the two ends of the threaded telescopic rod 95 being movably inserted into the corresponding movable sleeve 94.

[0029] Two positioning elements 92 are symmetrically welded on the inner wall of the annular recess of the fixed sleeve 91. Each positioning element 92 is movably installed in the corresponding rotating groove 93. The rotating groove 93 is opened on the inner wall of the movable sleeve 94. The side of the rotating groove 93 has a C-shaped structure. The inner wall of the movable sleeve 94 is in movable contact with the inner wall of the annular recess of the fixed sleeve 91. The maximum rotation angle of the movable sleeve 94 on the fixed sleeve 91 is 240°.

[0030] When the two sets of vertical poles 1 of the scaffolding are set on stairs of different heights, in order to facilitate the support of the threaded telescopic rod 95 between the two connecting frames 9, the installer can rotate the movable sleeve 94. When the movable sleeve 94 rotates, it will drive the rotating groove 93 to rotate on the outer wall of the positioning part 92 on the outer wall of the fixed sleeve 91, so that the two movable sleeves 94 can be kept in a relative state, so that the threaded telescopic rod 95 can be effectively supported between the two connecting frames 9.

[0031] In practical use, firstly, adjust the screw 6, which is set at the height of the scaffolding, downwards vertically. The bottom of the screw 6 is connected to the transmission plate 4 via a bearing 5. When the screw 6 moves downwards, it drives the transmission plate 4 to move downwards synchronously. The transmission plate 4 moves downwards along the trajectory of the vertical rod 1. When the transmission plate 4 moves downwards, the support at the bottom of the two corresponding sleeves 2 is released. At this time, under the action of gravity, the sleeves 2 move downwards vertically, thus causing the corresponding side of the pedal 3 to move downwards.

[0032] When pedal 3 is in a completely horizontal position, stop adjusting the corresponding screw 6. The self-locking property of screw 6 and the threaded hole will fix the transmission plate 4 in its current position. After completing the horizontal adjustment of pedal 3, proceed to the scaffolding lateral reinforcement stage. Take out the threaded telescopic rod 95, whose length is adjustable. Insert one end of the threaded telescopic rod 95 into the hole on the outer wall of one of the movable sleeves 94, and rotate the threaded telescopic rod 95 to bring it closer to the other movable sleeve 94.

[0033] After the threaded telescopic rod 95 is inserted into the hole of another movable sleeve 94, continue to rotate the threaded telescopic rod 95 to secure it between the two movable sleeves 94. Through the coordinated operation of the aforementioned components such as the screw 6, transmission plate 4, sleeve 2, tread 3, movable sleeve 94, and threaded telescopic rod 95, the scaffolding can adapt to the slope of the stairs and the height of the steps, ensuring a stable and safe operating condition even in complex terrain.

[0034] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
