Description

Technical Field

[0001] This utility model belongs to the technical field of building lifting equipment, and in particular relates to a building lifting base frame. Background Technology

[0002] In construction, lifting scaffolds (also known as hoisting platforms or scaffolding) are indispensable equipment used to lift workers and materials to different heights. However, when existing lifting scaffolds are raised to higher positions, their overall center of gravity also rises, making them highly susceptible to swaying due to external forces (such as wind loads or personnel movement) or uneven ground, and even posing a significant safety hazard of tipping over. While existing technologies offer solutions to enhance stability through guide rail clips or top ropes, these structures often suffer from complex installation, inconvenient use, and fail to fundamentally resolve the conflict between versatility and convenience. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a lifting base frame for construction, which improves the stability of the lifting platform while ensuring ease of use.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a building lifting base frame, including a base, on which a lifting platform is provided; a telescopic support mechanism is installed on the base, the telescopic support mechanism including a central shaft, the central shaft being rotatably mounted on a drive cabin, the drive cabin being provided with a drive assembly for driving the central shaft to rotate, the drive assembly being signal-connected to a control element; a central rod is provided on the central shaft, with rotating shafts at both ends of the central rod, and support seats are rotatably mounted on the rotating shafts, the support seats at both ends of the central rod are always parallel, a plurality of connecting rods are provided between the support seats, the two ends of the connecting rods are respectively hinged to the corresponding support seats, and the connecting rods are always parallel to the central rod; when the support seat is in the initial position below the base, the bottom of the support seat is not lower than the bottom of the base; when the support seat moves to its limit position to both sides of the base, the bottom of the support seat is not higher than the bottom of the base.

[0005] Preferably, the center rod can rotate synchronously under the drive of the center shaft, and the center rod can move relative to the center shaft along the axial direction. The bottom of the center shaft is provided with a limiting platform to restrict the separation of the center rod from the center shaft. A reset spring is provided between the limiting platform and the center rod, and the two ends of the reset spring press against the limiting platform and the center rod respectively. The top of the connecting rod is provided with a pressing platform. When the support moves outward from the base, the pressing platform will interfere with the base, and the base will press the pressing platform to move downward along the central axis.

[0006] Preferably, the rotating shaft is provided with a stop platform, the support seat can rotate synchronously under the drive of the rotating shaft, the support seat can move relative to the rotating shaft along the axial direction, and a support compression spring is sleeved on the rotating shaft, with both ends of the support compression spring pressing against the stop platform and the support seat.

[0007] Preferably, the end of the extrusion table facing the outer side of the base is an arc-shaped section.

[0008] Preferably, the extrusion table is provided with a lubricant.

[0009] Preferably, the lubricant is a ball bearing, which is evenly distributed along the surface of the extrusion table.

[0010] Preferably, in the initial position, the curved platform segment is at least partially in contact with and pressed against the base.

[0011] Preferably, a reinforcing rod is rotatably mounted on the central shaft, the reinforcing rod being hinged to the connecting rod and arranged parallel to the support seat.

[0012] Preferably, the support base includes a connecting part and a supporting part, the connecting part being rotatably connected to the rotating shaft, and the supporting part being fixed to the bottom of the connecting part, which can be pressed into contact with the ground.

[0013] The technical advantages of this utility model are as follows: Through the telescopic and automatically leveling linkage support structure, the support span is expanded and real-time self-stabilization is achieved under high center of gravity conditions, which solves to a certain extent the problems of easy shaking and tipping of traditional lifting base frames, and improves mobility, maintainability and adaptability to multiple scenarios.

[0020] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0021] like Figures 1-5 As shown, a building lifting frame includes a base 1, and a lifting platform 11 is installed on the top of the base 1. The lifting platform 11 is existing technology and can be a commonly used scissor lift platform 11.

[0022] Furthermore, a telescopic support mechanism is installed at the bottom of the base 1, and feet 12 are provided on the front and rear sides of the base 1; the telescopic support mechanism includes a central shaft 2, and a drive compartment 3 is provided at the bottom of the base 1. A drive assembly is provided inside the drive compartment 3. The drive assembly is existing technology and can be a drive motor and its matching reducer. The drive motor is signal-connected to a control element, which can be an existing PLC or microcontroller; the drive motor is connected to the central shaft 2 through the output end of the reducer; the central shaft 2 includes a round shaft segment and a square shaft segment, which are sequentially arranged from the reducer towards the ground and integrally fixed. A reinforcing rod 21 is rotatably mounted on the circular shaft section, and the reinforcing rod can also slide relative to the circular shaft section; a central rod 22 is slidably connected to the square shaft section, and a square groove is provided in the center of the central rod 22. The square shaft section is inserted into the square groove, and a limiting platform 23 is provided at the bottom of the square shaft section. A return spring 231 is provided between the limiting platform 23 and the central rod 22, and the two ends of the return spring 231 press against the limiting platform 23 and the central rod 22 respectively; two connecting rods 24 are symmetrically hinged to the two ends of the reinforcing rod 21, and two support seats 4 are symmetrically hinged to the two ends of the central rod 22. The two ends of the connecting rods 24 are respectively hinged to the corresponding support seats 4.

[0023] Furthermore, the central rod 22 has rotating shafts 25 at both ends. The support base 4 includes a connecting part 41 and a supporting part 42. The connecting part 41 is rotatably connected to the rotating shaft 25, and the supporting part 42 is fixed to the bottom of the connecting part 41, allowing it to press against the ground. The rotating shaft 25 is rotatably connected to the support base 4, and the two support bases 4 are always arranged in parallel. The bottom of the rotating shaft 25 has a stop platform 26, and there is a movable space between the connecting part 41 and the supporting part 42. The stop platform 26 is located within the movable space, and a support compression spring 261 is sleeved on the rotating shaft 25. The two ends of the support compression spring 261 press against the top surface of the stop platform 26 and the bottom of the connecting part 41. The support base 4 can rotate synchronously under the drive of the rotating shaft 25, and the support base 4 can move relative to the rotating shaft 25 along its axial direction.

[0024] Furthermore, the connecting rod 24 is located above the support base 4, and its top is provided with a pressing platform 5. The end of the pressing platform 5 facing the outer side of the base 1 is an arc-shaped platform section 51. In the initial position, the arc-shaped platform section 51 is at least partially in contact with the base 1 for pressing, so as to facilitate better pressing contact when the pressing platform 5 and the base 1 are pressed towards each other. Roller balls 52 are evenly distributed along the platform surface of the pressing platform 5 to reduce wear on the pressing platform 5 and improve the smoothness of movement.

[0025] Furthermore, the limiting platform 23, the stopping platform 26, the pressing platform 5, and the support part 42 are all detachable installation structures to facilitate the replacement and maintenance of vulnerable parts, ensuring the reliability of the structure and its overall service life.

[0026] The specific implementation process of this utility model is as follows: When the lifting base moves to the designated position, the control drive motor drives the central shaft 2 to rotate. The central shaft 2 drives the support seat 4 to rotate and extend outward to the outside of the base 1. During this process, the support part 42 does not contact the ground at first. As the support seat 4 extends outward below the base, the pressing table 5, under the pressing action of the base 1, drives the support seat 4 to move downward along the guide of the central shaft 2 and the rotating shaft 25. The support part 42 will eventually press against the ground, thereby increasing the support area.

[0027] The above description is only a specific embodiment of the present utility model, but the structural features of the present utility model are not limited thereto. The present utility model can be used in similar products. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
