A building structure support replacement device

Abstract

This utility model relates to the field of building construction, and more particularly to a structural support replacement device. It includes an upper frame with two symmetrical support legs rotatably connected to its lower part. A first protective cover is located on the front of the upper frame, and a second protective cover is located on the rear. An adjustment assembly is provided between the first protective cover and the left support leg. Two gears are rotatably installed inside the second protective cover, meshing with each other and connected to their respective support legs. This utility model uses a worm gear to drive the adjustment of the angle of the left support leg, supplemented by gear meshing to force synchronization of the right support leg, ensuring symmetrical expansion or contraction of both legs. This avoids the risk of overturning and collapse caused by uneven force on one side, improving the stability and safety of the support. A threaded rod drives a piston to compress liquid and push a lifting seat, achieving precise stepless lifting of the load support point height. This eliminates the need for manual heightening and disassembly, improving adjustment efficiency and accuracy, and ensuring uniform force distribution.

Description

Technical Field

[0001] This utility model relates to the field of building construction, and in particular to a building structure support replacement device. Background Technology

[0002] In construction engineering, especially in scenarios such as deep foundation pit support, structural demolition and alteration, or temporary building support, temporary or dynamic support structures are often required to transfer loads or maintain structural stability. Traditional support devices mostly use fixed support legs or simple folding structures, which have limited adjustment angles and are difficult to precisely control the synchronous unfolding / retraction of support legs. They are prone to imbalance risks due to asymmetrical support. Height adjustment often relies on manually inserting pin holes or stacking pads, which is cumbersome, inefficient, and difficult to achieve fine-tuning. In addition, there are problems such as insufficient preload or uneven force at the support points.

[0003] Therefore, a building structure support replacement device is being developed to address the above problems. Utility Model Content

[0006] Furthermore, it is particularly preferred that the upper part of the upper frame is also included, the upper part of the upper frame is slidably connected to the upper frame, the upper frame is filled with liquid, the right side of the upper frame is slidably connected to a piston, a cover plate is installed on the right side of the upper frame, a kit is provided on the cover plate, a threaded rod is threadedly connected to the kit, and the threaded rod is rotatably connected to the piston.

[0007] Furthermore, it is particularly preferred that the system also includes a lifting component, which is slidably connected to each of the support legs. Each of the lifting components is threadedly mounted with a fastener, and each of the fastening rings is rotatably connected with a rotating ring. Each of the rotating rings is rotatably provided with a protective plate with an arc-shaped structure.

[0008] Furthermore, it is particularly preferred that the bottom of the support leg is rotatably connected to a circular support foot.

[0009] Furthermore, it is particularly preferred that the adjusting assembly consists of a worm gear and a worm shaft.

[0010] Furthermore, it is particularly preferred that the cover plate and the upper top frame have a detachable connection structure.

[0011] By adopting the above technical solution, the beneficial effects of this utility model are:

[0012] This invention uses a worm gear to drive and adjust the angle of the left support leg, supplemented by gear meshing to force synchronization of the right support leg, ensuring that the two legs are symmetrically extended or retracted, avoiding the risk of overturning and collapse caused by uneven force on one side, and improving the stability and safety of the support. The threaded rod drives the piston to compress liquid and push the lifting seat to achieve precise stepless lifting of the load support point height, eliminating the need for manual heightening and disassembly, improving adjustment efficiency and accuracy, and ensuring uniform force distribution.

Detailed Implementation

[0019] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] A building structure support replacement device, such as Figures 1-5As shown, it includes an upper frame 1, with two symmetrical support legs 2 rotatably connected to the lower part of the upper frame 1. Circular support feet are rotatably connected to the bottom of each support leg 2. A first protective cover 3 is located on the front side of the upper frame 1, and a second protective cover 5 is located on the rear side. An adjustment assembly 4 is located between the first protective cover 3 and the left support leg 2. The adjustment assembly 4 consists of a worm gear and a worm shaft. Two gears 6 are rotatably installed inside the second protective cover 5, meshing with each other. Each gear 6 is connected to a corresponding support leg 2. A lifting mechanism is slidably connected to the upper part of the upper frame 1. The upper frame 1 is filled with liquid. A piston 8 is slidably connected to the right side of the upper frame 1. A cover plate 9 is installed on the right side of the upper frame 1. The cover plate 9 and the upper frame 1 are detachably connected. A kit 11 is provided on the cover plate 9. A threaded rod 10 is threadedly connected to the kit 11. The threaded rod 10 is rotatably connected to the piston 8. Lifting components 12 are slidably connected to the support legs 2. Fasteners 13 are threadedly installed on the lifting components 12. Rotating rings 14 are rotatably connected to the fastening rings. A protective plate 15 with an arc structure is rotatably provided on the rotating rings 14.

[0021] It should be noted that the operator first applies the action through the front adjustment component 4 of the device, specifically by rotating the worm gear. The worm gear meshes with the worm wheel. Due to the self-locking property of the worm gear transmission, rotating the worm gear precisely drives the worm wheel to rotate. Since the worm wheel is coaxially fixed with the left support leg 2 of the device, the rotation of the worm wheel will drive the left support leg 2 to rotate around its rotational connection point with the lower part of the upper frame 1. At the same time, in order to ensure that the symmetrical opening or closing of the left and right support legs 2 is synchronized, two meshing gears 6 are installed inside the second protective cover 5 on the rear side of the device. These two gears 6 are connected to the corresponding left and right support legs 2, respectively. Therefore, when the left support leg 2 starts to rotate due to the worm gear drive, it will drive the left gear 6 to rotate. The rotation of the left gear 6 drives the right gear 6, which meshes with it, to rotate. The rotation of the right gear 6 then causes the right support leg 2 to rotate around its upper end at the rotational connection point with the upper frame 1, in the opposite direction to the left support leg 2. This achieves the symmetrical expansion or contraction of the two support legs 2, ultimately causing the circular support feet connected to the bottom of the support legs 2 to contact and stably support the predetermined working surface. When it is necessary to raise or lower the load support point on the upper part of the device, this can be achieved by operating the lifting mechanism on the right side of the device. This mechanism consists of a sealed liquid chamber inside the upper frame 1, a lifting seat 7 slidably connected to the upper inner cavity of the upper frame 1, a piston 8 slidably engaged in the liquid chamber on the right side of the upper frame 1, and a threaded rod 10 assembly that drives the piston 8. The specific operation is as follows: The threaded rod 10 rotates within the cover plate 9. Since the threaded rod 10 is threadedly engaged with the assembly 11 on the cover plate 9, and the cover plate 9 is fixed to the right end of the upper top frame 1 via a detachable structure, and the threaded rod 10 is also rotatably connected to the piston 8, this means that the threaded rod 10 rotates without generating axial displacement relative to the piston 8. Therefore, when the threaded rod 10 rotates within the assembly 11, under the action of the threaded pair, the threaded rod 10 itself will generate axial displacement relative to the assembly 11. Because the threaded rod 10 is rotatably connected to the piston 8, this axial displacement will directly push or pull the piston 8 to slide within the liquid cavity inside the upper top frame 1. The movement of the piston 8 squeezes or releases the sealed liquid inside the upper top frame 1 (this liquid serves as the hydraulic medium). Since the liquid is incompressible, the pressure generated by the piston 8 will... The liquid is evenly transferred to the bottom of the chamber where the lifting seat 7 is located, thereby pushing or releasing the lifting seat 7 to slide upward (lifting) or downward (lowering) relative to the upper frame 1 in the vertical direction. This causes the building structure or load placed on the lifting seat 7 to rise or fall accordingly, achieving the purpose of adjusting the support height. In addition, adjustable additional protective components are provided on both sides of the support legs 2 to cope with complex operating environments. The protective components include a lifting component 12 that slides on the outside of the support legs 2. The lifting component 12 can be fixed at any desired height position at any time by fasteners 13 that are threaded on it. A rotating ring 14 is rotatably connected to the lifting component 12, and the rotating ring 14 is further rotatably connected to an arc-shaped protective plate 15.This multi-rotation structure design allows operators to first loosen the fasteners 13 and manually slide the lifting component 12 up and down to a suitable height on the support leg 2, according to on-site protection requirements. Then, they can tighten the fasteners 13 to lock the lifting component 12 in that position. Afterward, regardless of the height at which the lifting component 12 is fixed on the support leg 2, the operator can still freely rotate the rotating ring 14 to drive the protective plate 15 to rotate, and independently rotate the protective plate 15 itself. This allows for flexible arrangement of arc-shaped protective plates 15 on both sides of the device, forming a physical barrier that effectively prevents debris or tools scattered around the construction area from accidentally falling and injuring personnel or equipment. At the same time, the protective plate 15... The 5 degrees of rotational freedom ensure that even with the lifting component 12 fixed, the protective plate 15 will not hinder the operator from adjusting the support leg 2 or the lifting mechanism, improving the overall safety and convenience of operation. In summary, this device cleverly integrates the worm gear-driven deployment and retraction of the support leg 2, the symmetrical movement of the two legs ensured by the gear 6 synchronization mechanism, the hydraulic lifting principle of the screw-driven piston 8 to achieve stepless height adjustment, and multi-degree-of-freedom adjustable protective components. It constitutes a compact, functional, stable, and highly safe building structure support replacement device, especially suitable for construction site environments requiring frequent adjustments to the support point position and height.
