Description

Technical Field

[0001] This utility model relates to the technical field of construction lifting platforms, and in particular to a construction lifting platform with high stability. Background Technology

[0002] In the construction industry, scissor lifts are core equipment for high-altitude operations, and their stability directly affects the safety of workers and construction efficiency. Traditional scissor lifts generally use fixed bases or simple folding outriggers. Accidents at height are often related to insufficient equipment stability, especially in complex scenarios such as exterior wall construction and installation of irregular structures, where the mechanical support structure of traditional equipment can hardly meet safety regulations.

[0003] The core problem of the low stability of the base support of traditional scissor lift platforms stems from the inherent limitations of their mechanical structure. Traditional equipment often uses a parallelogram scissor arm structure. This design can maintain its basic shape when unloaded through hydraulic rods, but when fully loaded, the base support system has a fundamental flaw: the fixed outrigger design physically limits the support span, and on hard ground, the insufficient contact area of ​​the outriggers leads to pressure concentration, which easily results in a higher accident rate for traditional scissor lift platforms in complex construction environments. Summary of the Invention

[0004] Therefore, it is necessary to address the problem that the fixed outrigger design of traditional scissor lifts physically limits the support span during full-load operation, and the insufficient contact area of ​​the outriggers on hard ground leads to pressure concentration, which easily results in a high accident rate for traditional scissor lifts in complex construction environments. To provide a more stable construction lift platform, it is necessary to address the issue that the fixed outrigger design of traditional scissor lifts physically limits the support span, and the insufficient contact area of ​​the outriggers on hard ground leads to pressure concentration.

[0005] A highly stable construction lifting platform includes: a lifting platform body, a base fixedly connected to the lower part of the lifting platform body, rotating shafts movably connected around the base, and an extension column fixedly connected to one side of each of the multiple rotating shafts.

[0006] A drive assembly, located inside the base, is used to drive the shaft to rotate.

[0007] In one embodiment, the end of the extension column is hinged to an adjustable foot, the bottom of which is provided with anti-slip texture or replaceable rubber pad.

[0008] In one embodiment, the extension column is a multi-stage telescopic structure, and the surface of the extension column is marked with scale markings for manual calibration of the support length.

[0009] In one embodiment, the base has limiting grooves on both sides, and the extension column and the foot rotate around the pivot and are located inside the limiting grooves.

[0010] In one embodiment, the outer wall of the base is provided with a guide groove, which communicates with the limiting groove, and the foot is located inside the guide groove.

[0011] In one embodiment, the base is symmetrically fixedly connected with reinforcing plates inside, and the upper and lower sides of the two reinforcing plates support the inner wall of the base.

[0012] In one embodiment, the drive assembly includes gears that rotate inside the base, a drive belt that is movably disposed above every two gears, one of the gears being fixedly connected to a motor via an internal shaft, and one side of each of the two gears being meshed with two shafts respectively. Beneficial effects

[0013] 1. The base of the lifting platform is fixedly connected to the bottom by high-strength bolts. Four sets of rotating shafts are symmetrically distributed and movably connected around the base. Each set of rotating shafts is fixedly connected to an extension column on the outside. The extension column is driven to unfold along the limiting groove opened on the side wall of the base. The extension column adopts a three-stage hydraulic telescopic structure. After being fully unfolded, the support span is increased. The extension column and the base effectively disperse the impact of off-center load. The lifting platform body automatically adjusts the support angle according to the ground hardness to ensure that it can maintain a horizontal state under different working conditions, which significantly improves the safety of high-altitude operations.

[0014] 2. The drive assembly adopts a dual-motor synchronous drive architecture. The motor is a high-precision servo motor. The motor output shaft is rigidly connected to the gear through a tensioning sleeve. The transmission belt adopts a synchronous toothed belt structure. The surface-pressed teeth and the pulley power transmission have zero backlash. When the motor starts, the dual gears drive the two rotating shafts to rotate synchronously in opposite directions through reverse meshing, which drives the extension column to unfold. With the electromagnetic brake built into the motor, a mechanical self-locking is formed. Even when the power is off, the extension column can still maintain its unfolding angle, which significantly improves the wind load resistance. Attached Figure Description

[0027] The following is combined Figures 1-4 This utility model describes a highly stable construction lifting platform.

[0028] In one embodiment, a highly stable construction lifting platform includes: a lifting platform body 100 and a drive assembly 500. A base 200 is fixedly connected to the lower part of the lifting platform body 100, and rotating shafts 300 are movably connected around the base 200. An extension column 400 is fixedly connected to one side of each of the multiple rotating shafts 300. The drive assembly 500 is disposed inside the base 200 for driving the rotating shafts 300 to rotate.

[0029] In this embodiment, a base 200 is fixedly connected to the bottom of the lifting platform body 100 by high-strength bolts. Four sets of rotating shafts 300 are symmetrically distributed and movably connected around the base 200. An extension column 400 is fixedly connected to the outside of each set of rotating shafts 300. The extension column 400 is driven to unfold along the limiting groove 201 opened on the side wall of the base 200. The extension column 400 adopts a three-stage hydraulic telescopic structure. After being fully unfolded, the support span is increased. The extension column 400, together with the base 200, effectively disperses the impact of off-center load. The lifting platform body 100 automatically adjusts the support angle according to the ground hardness to ensure that it can maintain a horizontal state under different working conditions, which significantly improves the safety of high-altitude operations.

[0030] like Figure 1 Figure 2 and Figure 3As shown, the extension column 400 is hinged to an adjustable foot 401 at its end. The bottom of the foot 401 is provided with anti-slip texture or replaceable rubber pad. The extension column 400 has a multi-stage telescopic structure, and the surface of the extension column is provided with scale markings for manual calibration of the support length.

[0031] In this embodiment, the end of the extension column 400 is hinged with an adjustable foot 401. The bottom of the foot 401 adopts a dual-mode anti-slip design. Its main body is a high-strength alloy base, and the surface is pressed with honeycomb anti-slip texture to enhance the friction coefficient with hard ground. At the same time, it is nested with replaceable rubber shock-absorbing pads to adapt to soft ground.

[0032] like Figure 1 Figure 2 and Figure 3 As shown, the base 200 has limiting grooves 201 on both sides. The extension column 400 and the foot 401 rotate around the pivot 300 and are located inside the limiting grooves 201. The outer wall of the base 200 has a guide groove 203, which is connected to the limiting groove 201. The foot 401 moves inside the guide groove 203. The base 200 is symmetrically fixed with reinforcing plates 202 inside. The upper and lower sides of the two reinforcing plates 202 support the inner wall of the base 200.

[0033] In this embodiment, the limiting groove 201 adopts an arc-shaped guide rail structure, and its inner wall is chrome-plated to reduce the coefficient of friction, ensuring that the extension column 400 rotates smoothly within the range of the limiting groove 201. The guide groove 203 is chamfered at the connection with the limiting groove 201 to avoid jamming when the foot 401 moves. The limiting groove 201 and the guide groove 203 respectively accommodate the extension column 400 and the foot 401, reducing the area occupied by the foot 401 and the extension column 400 when the base 200 is not working. The reinforcing plate 202 is made of Q460 high-strength steel plate bent and formed, with a thickness of 8mm. It forms a closed cavity structure with the inner wall of the base 200 through laser welding, which increases the bending section modulus of the base 200 and makes the lifting platform body 100 rise stably, which is significantly better than the traditional manual adjustment method.

[0034] like Figure 2 Figure 3 and Figure 4 As shown, the drive assembly 500 includes gears 501 that rotate inside the base 200. A transmission belt 503 is movably provided above every two gears 501. One of the gears 501 is fixedly connected to a motor 502 via an internal shaft. One side of each of the two gears 501 is respectively meshed with two rotating shafts 300.

[0035] In this embodiment, the drive component 500 adopts a dual-motor 502 synchronous drive architecture. The motor 502 is a high-precision servo motor 502. The output shaft of the motor 502 is rigidly connected to the gear 501 through a shrink sleeve. The transmission belt 503 adopts a synchronous toothed belt structure. The surface-pressed teeth and the pulley power transmission have zero backlash. When the motor 502 starts, the dual gears 501 drive the two rotating shafts 300 to rotate synchronously in opposite directions through reverse meshing, which drives the extension column 400 to unfold. With the electromagnetic brake built into the motor 502, a mechanical self-locking is formed. Even when the power is off, the unfolding angle of the extension column 400 can still be maintained, which significantly improves the wind load resistance.

[0036] Working principle: During operation, the high-precision servo motor 502 starts and drives the gear 501 to rotate through the tension sleeve. The synchronous transmission belt 503 transmits power to the gears 501 on both sides, causing the symmetrically distributed rotating shafts 300 to rotate synchronously in opposite directions. The extension column 400 extends to the preset length according to the scale markings. The adjustable feet 401 contact the ground, and their honeycomb anti-slip texture or rubber pads adapt to the contact state according to the ground hardness. The electromagnetic brake of the motor 502 forms a mechanical self-locking mechanism to ensure that the support angle remains constant in the event of power failure, significantly improving the wind load resistance of the lifting platform body 100 and the safety of high-altitude operations.

[0037] It should be noted that the lifting platform body 100 and motor 502 mentioned above are all components with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the lifting platform body 100 and motor 502 can be powered by the built-in power supply or by the mains power. The specific power supply method should be selected according to the situation, which will not be elaborated here.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
