Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a building construction platform. Background Art

[0002] During the construction process, the building exterior walls or places with high floor heights that cannot be directly constructed, such as beams, need to be built on platforms, and workers climb onto the platforms to work. In order to reduce the tediousness and time loss of platform building, lifting platforms are now used for work.

[0003] The lifting platform mainly includes a base and a platform that can be lifted and lowered on the base. Nowadays, the lifting of the platform is mostly controlled by the folding and unfolding of the staggered rotating brackets (forming an X shape). One end of the bracket is rotatably installed on the base and the other bracket is controlled by a hydraulic rod or a screw group to move closer or farther to achieve the lifting of the platform. However, it should be understood that the upper ends of the two brackets are also connected to the bottom wall of the platform, one of which is rotatably connected, and the other is slidably connected to the bottom wall of the platform, so that the opening and closing of the two brackets can be achieved. This setting causes the support point on one side of the platform to be unfixed, and the higher the platform rises, the closer the movable support point is to the center of the platform. In this way, under the load, it is easy to cause the platform to deviate to the side, affecting the stability of the platform. In addition, most platforms on the market can only be adjusted vertically, and it is difficult to adjust the position after lifting, especially for workers working on the exterior walls. They need to stop and adjust the position of the base several times before they can continue to work, which greatly affects work efficiency.

[0004] To this end, the present application provides a construction platform to solve the problems of the platform's lifting drive device being unreliable and the position adjustment being inconvenient. Utility Model Content

[0015] Compared with the prior art, this application provides a building construction platform with the following beneficial effects:

[0016] 1. When in use, the two lower sliders are controlled by the driving device to move toward each other, so that the lower ends of the two brackets on the same side are close to each other, and the lifting platform rises.

[0017] 2. The position of the lifting platform can be adjusted by driving the construction platform to move; the mounting base can be driven to deflect through the turntable, thereby driving the lifting platform to deflect to adapt to usage scenarios under different conditions and improve the flexibility and practicality of the equipment.

DETAILED DESCRIPTION

[0026] The following will be combined with the attached examples of the present application Figure 1-6 , the technical solutions in the embodiments of the present application are described clearly and completely. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0027] In order to solve the problems existing in the prior art, the present embodiment provides a construction platform, including a mobile construction platform 1, a turntable 2 is provided on the construction platform 1, a mounting seat 3 is provided on the rotating output surface of the turntable 2, a lifting platform 8 is vertically slidably installed on the mounting seat 3, upper sliders 5 are symmetrically slidably installed on both sides of the bottom end of the lifting platform 8, and a support frame 4 is rotatably installed on the bottom end of the upper slider 5. The two support frames 4 on the same side are cross-rotatably connected and the bottom ends of the two support frames 4 are rotatably installed with lower sliders 6, and the two lower sliders 6 are driven by a driving device to move toward or away from each other.

[0028] Principle details of this embodiment:

[0029] A construction platform includes a construction platform 1, and four wheels are distributed around the bottom of the construction platform 1. The wheels have a brake system and are driven by a drive system, so that the construction platform 1 can be transferred. A turntable 2 is provided on the construction platform 1, and a mounting seat 3 is provided on the rotating output surface of the turntable 2. A lifting platform 8 is vertically slidably installed on the mounting seat 3. A fence is provided on the upper end of the lifting platform 8 to prevent workers from falling out; doors are rotatably installed around the fence, so that workers and items do not need to climb over when moving, thereby improving safety; and a lock is provided at the port of the door, so that the door can only be opened by the workers themselves, preventing accidents caused by accidental opening of the door. Upper sliders 5 are symmetrically slidably installed on both sides of the bottom of the lifting platform 8, and a support frame 4 is rotatably installed on the bottom of the upper slider 5. The two supports 4 on the same side are cross-arranged (in an X shape) and the intersection is the rotation axis of the two supports 4. Lower sliders 6 are rotatably installed on the bottom of the supports 4, and the two lower sliders 6 are driven by a driving device to move toward or away from each other.

[0030] When in use, the two lower sliders 6 are controlled by the driving device to move toward each other, so that the lower ends of the two support frames 4 on the same side are close to each other, the angle between the two support frames 4 becomes smaller, and the lifting platform 8 is lifted up. Since the lifting platform 8 is vertically slidably connected to the mounting seat 3, a vertical guide restriction is given to the lifting platform 8, so that the lifting platform 8 can only move vertically under the action of the support frame 4 to prevent the lifting platform 8 from shifting; and because the lifting platform 8 can only move vertically, the upper ends of the two support frames 4 on the same side are also gradually close to each other, so that the support points of the lifting platform 8 are always symmetrically distributed along the center, avoiding the support from being unstable due to the shift of one side of the support point, and improving the support stability. At the same time, the position adjustment of the lifting platform 8 can be achieved by driving the construction platform 1 to transfer; the mounting seat 3 can be driven to deflect by the turntable 2, thereby driving the lifting platform 8 to deflect, so as to adapt to the use scenarios under different conditions and improve the flexibility and practicality of the equipment.

[0031] In this embodiment, a number of universal balls are evenly distributed on the end surface of the construction platform 1, and the universal balls are against the bottom surface of the mounting seat 3, which not only improves the support for the mounting seat 3, but also reduces the contact surface and less deflection friction resistance.

[0032] In this embodiment, the turntable 2 includes a rotating base and a rotating output surface. The end surface of the construction platform 1 is provided with an inner cavity. The rotating base is embedded in the inner cavity and is rotatably installed in the inner cavity. The rotating output surface is exposed to the outside. The rotating base is driven by a rotating motor fixed in the inner cavity through a gear set. The rotating output surface of the turntable 2 is connected to the mounting seat 3 through a fastener. The bottom wall of the inner cavity is detachable and fixed to the bottom wall of the construction platform 1 through a fastener, which is convenient for disassembly and assembly of the turntable 2. A plurality of air holes 14 are evenly distributed on the bottom wall of the inner cavity for heat dissipation and exhaust.

[0033] In this embodiment, a connecting shaft is provided between the two opposing supports 4 to increase the connection strength of the supports 4 .

[0034] In a further embodiment of the present scheme, the mounting seat 3 and the construction platform 1 are both rectangular, which are compatible with the traditional construction platform, and the size of the mounting seat 3 is larger than that of the construction platform 1, so that the periphery of the mounting seat 3 is exposed, and hydraulic rods 12 are arranged around the exposed part of the bottom end of the mounting seat 3, and the extended ends of the hydraulic rods 12 are provided with universal wheels 13. When the turntable 2 deflects, the hydraulic rods 12 extend, and the universal wheels 13 are against the ground and rotate with the mounting seat 3, providing an auxiliary support for the extended part of the mounting seat 3 relative to the construction platform 1, so that the deflection of the mounting seat 3 is more stable, and the stability of the position adjustment of the lifting platform 8 is improved.

[0035] In a further embodiment of the present scheme, the driving device includes two bidirectional screws 7 symmetrically rotatably mounted on the surface of the mounting seat 3. The two bidirectional screws 7 are connected via a belt drive and driven by a motor fixed on the mounting seat 3. The two lower sliders 6 on the same side are symmetrically threadedly mounted on the bidirectional screws 7.

[0036] In a further embodiment of the present scheme, support pads 10 are provided on all four sides of the surface of the mounting seat 3, and the end faces of the support pads 10 are located above the motor. When in the storage state, the lifting platform 8 is supported to avoid being pressed on other components, while the support frame 4 is always kept in an inclined state to facilitate the deflection of the support frame 4.

[0037] In a further embodiment of the present scheme, a plurality of pairs of supports 4 are vertically spaced apart on the mounting seat 3, the ends of adjacent supports 4 are rotatably connected, an upper slider 5 is arranged at the upper end of the uppermost support frame 4, and a lower slider 6 is arranged at the bottom end of the lowermost support frame 4, so as to increase the vertical moving height of the lifting platform 8.

[0038] In a further embodiment of the present scheme, two slide rails 11 made of I-beams are symmetrically provided at the bottom of the lifting platform 8, and the upper slider is a fastener that cooperates with the slide rail 11 to achieve a sliding connection between the upper slider 5 and the lifting platform 8.

[0039] In a further embodiment of the present scheme, telescopic rods 9 are provided around the surface of the mounting seat 3, and the extended ends of the telescopic rods 9 are fixedly connected to the bottom end of the lifting platform 8, and are guided by the telescopic rods 9 so that the lifting platform 8 can only move vertically; and after the telescopic rods 9 are retracted, their height does not exceed the fence, thereby reducing overhang and avoiding interference.

[0040] In a further embodiment of the present invention, the end surface of the lifting platform 8 is provided with a sinking surface to prevent the broken parts from leaking out and falling down and causing accidents. The bottom of the sinking surface is provided with a drainage port for draining sewage and other debris.
