Description

Technical Field

[0001] The invention relates to the field of building construction, and in particular to a self-stabilizing lifting platform for building construction. Background Art

[0002] When construction workers are performing aerial work during the construction process, they need to use a lifting platform to quickly and smoothly lift the workers and required materials to the construction site at a specified height, which increases the flexibility and convenience of the work.

[0003] During the construction process, in order to facilitate the operation, workers generally need to stand in the middle of the lifting platform, close to the building wall, causing the center of gravity of the lifting platform to be biased towards the side close to the building wall. In this way, the center of gravity of the platform will deviate from the center and become unbalanced, increasing the risk of overturning. Unbalanced loads may cause the lifting platform to shake during the process of rising, falling or moving, affecting the safety of operation and the comfort of riding. In some cases, serious imbalance may trigger the platform's safety protection devices, such as tilt sensors, causing the platform to automatically stop working, affecting construction efficiency.

DETAILED DESCRIPTION

[0039] The technical solution of the present invention is further described below in conjunction with the accompanying drawings.

[0040] Embodiment 1: A self-stabilizing lifting platform for construction, combined with the attached Figure 1 To Attachment Figure 6, including a base frame 1, a lifting platform 12 is set on the top of the base frame 1 through a scissor-type hydraulic lifting frame 11, a mounting plate frame 13 is fixedly connected in the middle of the base frame 1, and first spring pieces 14 symmetrically distributed along the mounting plate frame 13 are fixedly connected on both sides of the mounting plate frame 13, and a first cylinder piston assembly 15 symmetrically distributed along the mounting plate frame 13 is fixedly connected to the bottom of the mounting plate frame 13, and first guide rods 16 symmetrically distributed along the mounting plate frame 13 are fixedly connected inside the mounting plate frame 13, and moving weights 17 symmetrically distributed along the first guide rods 16 are slidably connected between the first guide rods 16 symmetrically distributed along the first guide rods 16, and the two moving weights 17 are initially located at the mounting plate frame 13. At the center balance position, the movable weight 17 is fixedly connected to the adjacent first elastic sheet 14, and the left and right sides of the inner bottom of the mounting plate frame 13 are fixedly connected with the second cylinder piston assembly 18 which is symmetrically distributed along the front and rear of the mounting plate frame 13, and the piston rod of the second cylinder piston assembly 18 is fixedly connected to the movable weight 17 on the other side, and the second cylinder piston assembly 18 is connected to the adjacent first cylinder piston assembly 15 on the same side through an air guide pipe 19, and the base frame 1 is provided with a power assembly 110 for driving the scissor-type hydraulic lifting frame 11 to lift and lower, and the front and rear sides of the base frame 1 are fixedly connected with the telescopic frames 111 which are symmetrically distributed along the left and right sides of the base frame 1, which are used to balance and support the front and rear sides of the lifting platform when it is slightly tilted forward or backward.

[0041] Initially, the two moving weights 17 are located in the middle of the mounting plate frame 13, so that the entire lifting platform is in a balanced state. When the construction workers approach the middle of the left side of the lifting platform 12 for construction, the center of gravity of the lifting platform is biased to the left, resulting in a tendency to tilt to the left. The piston rod end of the first cylinder piston assembly 15 on the left is squeezed by the ground on the left side, so that the gas in the cylinder of the first cylinder piston assembly 15 is injected into the cylinder of the second cylinder piston assembly 18 on the left through the air guide pipe 19 on the left. Under the action of air pressure, the piston rod of the second cylinder piston assembly 18 on the left pushes the moving weight 17 on the right to slide to the right along the first guide rod 16, and the first spring plate 14 on the right is compressed. When the piston rod of the first cylinder piston assembly 15 on the left is no longer compressed, the first spring plate 14 on the right is reset, so that the moving weight 17 on the right is reset;

[0042] Similarly, when the construction worker approaches the middle of the right side of the lifting platform 12 to perform construction, the movable weight 17 on the left side automatically moves to the left;

[0043] In this way, when construction workers are working on one side, the movable weight 17 on the other side automatically moves to the other side, achieving the effect of balancing the entire lifting platform, realizing the self-stabilizing function, preventing the center of gravity from leaning to one side during construction and causing imbalance, thereby improving the safety of construction.

[0044] Combined with Figure 7 To Attachment Fig.10, also includes a support frame 2 symmetrically distributed along the front and back of the mounting plate frame 13, the support frame 2 is slidably connected to the mounting plate frame 13, there are four support frames 2, which are respectively located at the front and rear parts of the left and right sides of the mounting plate frame 13, the support frame 2 is fixedly connected to two second guide rods 21, and a compression spring 22 is fixedly connected between the second guide rod 21 and the mounting plate frame 13, and the upper and lower sides of the mounting plate frame 13 are slidably connected to connecting rods 23 symmetrically distributed along the front and back of the mounting plate frame 13, and three elastic members 24 are fixedly connected between the connecting rods 23 and the mounting plate frame 13, the left end of the upper connecting rod 23 and the right end of the lower connecting rod 23 are fixedly connected to a block 25 for clamping the adjacent support frame 2, and the right end of the upper connecting rod 23 and the left end of the lower connecting rod 23 are fixedly connected to a top block 26 for extrusion-matching with the movable weight 17 adjacent to the same side.

[0045] When the right moving weight block 17 moves to the right, that is, the lifting platform tends to tilt to the left, the right moving weight block 17 contacts the upper top block 26 and squeezes the upper top block 26 to slide outward, thereby driving the upper connecting rods 23 of the front and rear sides to slide outward, the upper elastic member 24 is compressed, and the upper connecting rod 23 drives the upper clamping block 25 to release the left support frame 2 outward, and the compressed compression spring 22 is reset to drive the left support frame 2 and the second guide rod 21 to extend to the left;

[0046] Similarly, when the movable weight 17 on the left side moves to the left, that is, the lifting platform has a tendency to tilt to the right, the support frame 2 on the right side automatically extends to the right;

[0047] In this way, when construction workers are working on one side, the support frame 2 on that side will first contact the ground and be firmly supported on the ground, thereby reducing the tilt angle of that side.

[0048] Embodiment 2: Based on embodiment 1, Fig.11 To Attachment Fig.12 , and also includes a connecting pipe 3 corresponding to the air guide pipe 19, the connecting pipe 3 is connected to the corresponding air guide pipe 19, two elastic telescopic components 31 are fixedly connected in the air guide pipe 19, and a block 32 is fixedly connected between adjacent elastic telescopic components 31. Only when the force on the piston rod of the first cylinder piston assembly 15 reaches a certain level, the block 32 will move to the side close to the elastic telescopic component 31, so that the air guide pipe 19 is opened, which is used to prevent the piston rod of the first cylinder piston assembly 15 from sliding and inflating due to small vibrations. The outer end of the connecting pipe 3 is fixedly connected to a relief valve 33, which is used to discharge the gas in the cylinder of the second cylinder piston assembly 18.

[0049] In order to prevent small vibrations from causing the piston rod of the first cylinder piston assembly 15 to slide and inflate, the elastic force of the elastic telescopic assembly 31 is used to make the block 32 block the air duct 19. Only when the force on the piston rod of the first cylinder piston assembly 15 reaches a certain level, the block 32 is squeezed open for ventilation, thereby realizing the movement of the movable weight 17. Since the block 32 can only control the one-way entry of gas, the gas entering the cylinder of the second cylinder piston assembly 18 cannot flow back into the cylinder of the first cylinder piston assembly 15. The air relief valve 33 can be opened later to discharge the gas in the cylinder of the second cylinder piston assembly 18 through the connecting pipe 3, thereby resetting the movable weight 17.

[0050] Combined with Fig.13 To Attachment Fig.14 , and also includes a fixing frame 4 corresponding to the supporting frame 2, the fixing frame 4 is fixedly connected to the base frame 1, a fixing tube 41 is fixedly connected to the upper part of the fixing frame 4, the fixing tube 41 is slidably connected with three limit blocks 42 along the up and down directions, a second elastic piece 43 is fixedly connected between the limit block 42 and the adjacent fixing tube 41, and a limit hole 44 is opened on one side of the supporting frame 2 close to the limit block 42, and the limit hole 44 is limitedly matched with the adjacent limit block 42 to limit the supporting frame 2 moved outward to the corresponding position.

[0051] The outward movement of the support frame 2 drives the limit hole 44 to contact the adjacent limit block 42. Under the elastic force of the second spring piece 43 and the extrusion of the support frame 2, the limit block 42 adaptively moves up and down, and the limit block 42 is inserted into the limit hole 44, so that the support frame 2 moved outward to the corresponding position can be limited, thereby fixing the support frame 2 and improving the stability of the support of the support frame 2.

[0052] Embodiment 3: Based on Embodiment 2, Fig.15 To Attachment Fig.16 , and also includes a rotating rod 51 symmetrically distributed along the front and back of the mounting plate frame 13, the rotating rod 51 is rotatably connected to the mounting plate frame 13, a push block 5 is fixedly connected to the top of the rotating rod 51, the push block 5 on the front side is squeezed and matched with the moving weight block 17 on the left side, and the push block 5 on the rear side is squeezed and matched with the moving weight block 17 on the right side, a torsion spring 52 is wound around the rotating rod 51, and the two ends of the torsion spring 52 are respectively fixedly connected to the mounting plate frame 13 and the push block 5, and an arc guide block 53 symmetrically distributed along the front and back of the mounting plate frame 13 is fixedly connected to the middle of the bottom of the mounting plate frame 13, and a rotating weight block 54 is fixedly connected to the bottom end of the rotating rod 51, and the rotating weight block 54 is slidably connected to the adjacent arc guide block 53.

[0053] Initially, the rotating weight block 54 is located in the middle of the arc-shaped guide block 53. When the right moving weight block 17 automatically slides to the right, that is, the lifting platform tends to tilt to the left, the right moving weight block 17 is separated from the rear push block 5, and the rear torsion spring 52 resets to drive the rear push block 5 and the rear rotating rod 51 to rotate counterclockwise to reset. The rear rotating rod 51 drives the rear rotating weight block 54 to slide counterclockwise along the rear arc-shaped guide block 53, so that the rear rotating weight block 54 automatically deviates to the right.

[0054] Similarly, when the movable weight 17 on the left side automatically slides to the left, that is, the lifting platform tends to tilt to the right, the rotating weight 54 on the front side automatically deviates to the left;

[0055] In this way, when the construction workers are working on one side, the moving weight 17 on the other side automatically moves to the other side, and the rotating weight 54 in contact with the moving weight 17 on this side automatically deflects in the same direction, further balancing the entire lifting platform.

[0056] While the present invention has been described with reference to exemplary embodiments, it is to be understood that the invention is not limited to the disclosed exemplary embodiments.The scope of the following claims is to be accorded the broadest interpretation so as to encompass all such modifications and equivalent structures and functions.
