Description

Technical Field

[0001] This invention relates to a construction platform, and more particularly to a construction platform for building construction projects, belonging to the field of building engineering technology. Background Technology

[0002] In building construction, mobile platforms (such as masonry platforms and decoration operation platforms) are key equipment for high-altitude operations. Their support stability is directly related to construction safety and efficiency. Currently, the support structure of these platforms generally uses four sets of support legs for positioning. The platform can achieve stable contact with the ground by manually adjusting the extension of the support legs.

[0003] However, existing support methods have significant technical shortcomings in practical applications: On the one hand, when the load distribution on the top of the platform is uneven (such as workers being concentrated on one side or materials being stacked eccentrically), the stress state of the four sets of support legs will become drastically unbalanced. Some support legs will bear overload, while the other support leg may be suspended in the air, causing the overall center of gravity of the platform to shift, which can easily lead to tilting or even overturning accidents. This instability caused by uneven load is further amplified in high-altitude operation scenarios, seriously threatening the safety of construction workers.

[0004] On the other hand, the platform's working height is dynamically changing during construction. However, the existing support leg adjustment method is "pre-set manually," meaning that the outrigger extension must be manually adjusted before the platform is raised. Furthermore, it cannot be adjusted in real time according to height changes after the platform is raised. As the platform rises, its center of gravity shifts upwards, placing higher demands on the force balance and support span of the support legs. The outrigger extension that is suitable at lower heights will significantly reduce the overall anti-overturning capacity when the platform is raised to a higher position due to insufficient support radius and unreasonable force distribution. This mismatch between "static adjustment" and "dynamic height change" further exacerbates the stability risks of the platform during high-altitude operations. At the same time, frequent platform descents for outrigger readjustment also seriously affect construction efficiency.

[0005] Therefore, in response to the technical problems of existing four-legged support structures being prone to tilting under uneven load conditions and being unable to dynamically adjust their elongation according to the platform height, this invention designs a construction platform for building construction projects to optimize the above-mentioned problems. Summary of the Invention

[0006] The main objective of this invention is to provide a construction platform for building construction projects. The main support block, through the precise coordination of crossbars, slots, and sliders, forms an "adaptive triggering" mechanism that rises with the platform. When the platform rises, the angle change of the crossbars causes the slider to slide within the slots, simultaneously driving the main support block to move vertically downwards and closely contact the ground, instantly constructing a stable central support. This design ensures that the platform's vertical load can be directly and efficiently transferred to the ground through the main support block, avoiding the "suspended load" problem caused by the lag in manual adjustment of traditional support legs, significantly enhancing... The core vertical load-bearing capacity is ensured, while the corner support mechanisms on the outer side of the base serve as supplementary external stability. Through the coordinated action of fixed and movable rods, the support range extends to all sides of the platform. The main support block bears the central vertical load, while the corner supports resist lateral forces by dispersing the peripheral moment. The two form a division of labor system of "central load concentration and peripheral anti-eccentricity," effectively solving the tilting risk of existing platforms caused by load concentration or center of gravity shift. This allows the device to remain stable in high-center-of-gravity scenarios such as high-altitude operations, significantly improving its anti-overturning capability. The linkage design of the corner support mechanism and the horizontal telescopic mechanism achieves... The system features intelligent adjustment of support points that "move with height." The horizontal telescopic mechanism, through a precision transmission chain consisting of gears, racks, bevel gears, and shafts within the hollow box and the first transmission chamber, simultaneously triggers the fixed rod to extend horizontally, directly expanding the support radius. Simultaneously, with the cooperation of the push rod and the rotating rod, the movable rod rotates and unfolds around the fixed rod, flexibly adjusting the spatial distribution of the side support points to ensure balanced force distribution on the platform under complex working conditions. The entire adjustment process of the support system is fully automated through mechanical linkage; the downward movement of the main support block and the extension of the fixed rod... The retraction and rotation of the movable rods are directly triggered by the lifting and lowering of the platform, eliminating the need for manual pre-setting or mid-process adjustments. This design not only saves the tedious steps of frequently lowering the platform to manually adjust the outriggers, significantly reducing non-working time and improving construction efficiency, but also avoids adjustment errors that may occur during manual operation, thus eliminating safety hazards caused by human negligence from a mechanism perspective. In addition, the stability and durability of the mechanical transmission structure are adapted to the harsh environment of building construction, and it is less affected by dust and vibration compared to the electrical control system, reducing the probability of failure and further ensuring the long-term reliability of the platform.

The horizontal telescopic mechanism controls the fixed rod to move forward and backward respectively. Movable rods are hinged to the outer sides of the fixed rods. The ends of both the fixed rod and the movable rod are vertically mounted with second hydraulic cylinders. The output ends of the second hydraulic cylinders are all mounted with secondary support blocks. A rotating assembly for driving the movable rod to rotate horizontally is provided between the end of the base and the movable rod.

The ends of the two sets of push rods are fixedly connected to the rotating rods respectively.

[0012] Preferably, the horizontal telescopic mechanism includes a hollow box, a first gear, a first rack, and a drive assembly. The hollow box is fixed at the middle position of the end of the base.

Both sets of first racks are slidably connected to the hollow box, and the ends of the two sets of first racks are respectively fixedly connected to the fixed rod. The base is provided with a drive assembly for controlling the rotation of the first gear.

[0013] Preferably, the drive assembly includes a first transmission chamber, a first shaft, a second gear, a second rack, a first bevel gear, a second bevel gear, a second shaft, a second transmission chamber, a third gear, a fourth gear, and a third shaft.

[0017] The beneficial effects of this invention are as follows: This invention provides a construction platform for building construction projects. The main support block, through the precise cooperation of crossbars, strip grooves, and sliders, forms an "adaptive triggering" mechanism that rises with the platform. When the platform rises, the angle change of the crossbars causes the slider to slide within the strip groove, simultaneously driving the main support block to move vertically downward and closely adhere to the ground, instantly constructing a stable central support. This design ensures that the vertical load of the platform can be directly and efficiently transferred to the ground through the main support block, avoiding the "suspended force" problem caused by the lag in manual adjustment of traditional support legs, significantly enhancing the core vertical bearing capacity. At the same time, the corner support mechanism on the outer side of the base serves as a supplementary external stabilization mechanism, expanding the support range to the four sides of the platform through the coordinated action of fixed rods and movable rods. The main support block bears the central vertical load, while the corner supports resist lateral forces by dispersing the external moment. The two form a division of labor system of "central load concentration and peripheral anti-deviation," effectively solving the tilting risk of existing platforms caused by load concentration or center of gravity shift, enabling the device to remain stable in high-center-of-gravity scenarios such as high-altitude operations, and greatly improving the anti-overturning capability. The linkage design of the corner support mechanism and the horizontal telescopic mechanism realizes the intelligent adjustment of the support points "moving with the height". The horizontal telescopic mechanism forms a precision transmission chain through the gear rack, bevel gear set and shaft in the hollow box and the first transmission compartment. When the carrier plate rises, the transmission system synchronously triggers the fixed rod to extend in a straight line in the horizontal direction, directly expanding the support radius. At the same time, with the cooperation of the push rod and the rotating rod, the movable rod rotates and unfolds around the fixed rod, flexibly adjusting the spatial distribution of the side support points to ensure the platform is under balanced force under complex working conditions. The entire support system's adjustment process is fully automated through mechanical linkage. The downward movement of the main support block, the extension and retraction of the fixed rod, and the rotation of the movable rod are all directly triggered by the lifting and lowering of the carrier plate, eliminating the need for manual pre-setting or mid-process adjustments. This design not only saves the tedious steps of frequently lowering the platform to manually adjust the outriggers, significantly reducing non-working time and improving construction efficiency, but also avoids adjustment errors that may occur during manual operation, thus eliminating safety hazards caused by human negligence from a mechanism perspective. In addition, the stability and durability of the mechanical transmission structure are adapted to the harsh environment of building construction, and compared with the electrical control system, it is less affected by dust and vibration, reducing the probability of failure and further ensuring the long-term reliability of the platform.

[0020] To enable those skilled in the art to more clearly understand the technical solution of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

[0021] Example 1 like Figures 1-9As shown, this embodiment provides a construction platform for building construction projects, including a base 1, a movable wheel 101 rotatably installed at the bottom of the base 1, a carrier plate 102 disposed above the base 1, and a guardrail 103 surrounding the edge of the carrier plate 102. Lifting mechanisms 2 are connected between the two ends of the top of the base 1 and the carrier plate 102; The top two ends of the base 1 are provided with strip grooves 3 parallel to the length direction of the base 1. The inside of each strip groove 3 is slidably connected with a slider 4. The top of the slider 4 is hinged to the bottom of the carrier plate 102 with a cross rod 5. The bottom of each strip groove 3 is vertically provided with a vertical groove 6, and the interior of each vertical groove 6 is vertically slidably provided with a main support block 7; The main support block 7 body is made of 45 steel (surface hardening hardness HRC50~55), the bottom rubber layer is 10mm thick, the bottom of the main support block 7 is made of nitrile rubber (Shore hardness 60±5), and the anti-slip texture at the bottom of the main support block 7 is a cross grid pattern (depth 2mm, spacing 10mm). The top of the main support block 7 is attached to the bottom of the slider 4. The top of the main support block 7 is provided with a protrusion 8 in the moving direction of the slider 4. The connection between the top of the main support block 7 and the protrusion 8 is a slope. The slope angle is set to 45°±5° to ensure that the horizontal thrust of slider 4 can be efficiently converted into vertical downward pressure, and the edge of protrusion 8 is rounded (radius 2mm) to prevent slider 4 from getting stuck when sliding. The main support block 7 is equipped with a reset mechanism 9, which is used to control the main support block 7 to detach from the ground and move vertically upward to reset; The outer side of the base 1 is provided with a corner support mechanism 10, and both ends of the base 1 are provided with a horizontal telescopic mechanism 11. The corner support mechanism 10 is connected to the horizontal telescopic mechanism 11, and the horizontal telescopic mechanism 11 drives the corner support mechanism 10 to expand or contract to form auxiliary support.

[0022] Overall working principle: When the device needs to be raised, the lifting mechanism 2 drives the carrier plate 102 to move upward. The cross rod 5 hinged at the bottom of the carrier plate 102 pushes the slider 4 to slide inward along the strip groove 3 as the angle increases. The bottom of the slider 4 contacts the inclined surface at the top of the main support block 7. As the slider 4 moves, its pressure on the main support block 7 is converted into a vertical downward force along the inclined surface, pushing the main support block 7 to move downward along the vertical groove 6 until the bottom of the main support block 7 contacts the ground and is compacted. At this time, the reset spring 903 in the reset mechanism 9 is compressed and stores the elastic force.

[0023] Simultaneously, the movement of slider 4 drives the drive component of horizontal telescopic mechanism 11 to move. The second rack 1107 connected to slider 4 drives the second gear 1106 to rotate, causing the first shaft 1105 to rotate. Through the meshing transmission of the first bevel gear 1108 and the second bevel gear 1109, the power is transmitted through the second shaft 1110 to the third gear 1112 in the second transmission chamber 1111. The third gear 1112 drives the fourth gear 1113 to rotate, and then drives the first gear 1102 to rotate through the third shaft 1114, causing the first rack 1103 to extend to both sides along the hollow box 1101, pushing the fixed rod 1001 to move horizontally.

[0024] When the fixed rod 1001 moves, the push rod 1005 at the end of the base 1 drives the movable rod 1002 to rotate and unfold around the hinge point of the fixed rod 1001 through the rotating rod 1006 until the movable rod 1002 and the fixed rod 1001 form a preset angle. Then, the second hydraulic cylinder 1003 of the corner support mechanism 10 extends and pushes the auxiliary support block 1004 to contact the ground, forming a cooperative support with the main support block 7.

[0025] When the carrier plate 102 descends, the lifting mechanism 2 moves the carrier plate 102 downward, the cross bar 5 pushes the slider 4 outward to reset, the main support block 7 moves upward along the vertical groove 6 and detaches from the ground under the elastic force of the reset spring 903, at the same time the horizontal telescopic mechanism 11 reverses the transmission, the fixed rod 1001 retracts, the movable rod 1002 folds under the pull of the push rod 1005, the auxiliary support block 1004 retracts and resets with the second hydraulic cylinder 1003, and the entire device returns to its initial state.

[0026] Example 2 The solution in Example 1 will be further described below with reference to its specific working method. In this embodiment, the lifting mechanism 2 includes a vertical plate 201, a horizontal plate 202, a U-shaped frame 203, a fixed pulley 204, a steel cable 205, a fixing plate 206, and a first hydraulic rod 207. The vertical plate 201 is vertically fixed to both ends of the top of the base 1, and each end of the base 1 has two sets of vertical plates 201. A horizontal plate 202 connects the two sets of vertical plates 201 at the same end of the base 1. A U-shaped frame 203 is vertically slidably arranged between the two sets of vertical plates 201 at the same end of the base 1. A fixed pulley 204 is installed on the inner top of the 203. A steel cable 205 is wound on the fixed pulley 204. The top end of the steel cable 205 is fixedly connected to the horizontal plate 202. A fixing plate 206 is installed on the bottom end of the steel cable 205. The fixing plate 206 is vertically slidably arranged in the U-shaped frame 203. The fixing plate 206 is fixed to the end of the carrier plate 102. A first hydraulic rod 207 is vertically installed at both ends of the top of the base 1. The output end of the first hydraulic rod 207 is fixedly connected to the inner top of the U-shaped frame 203.

[0027] Local working principle: The first hydraulic rods 207 on both sides are controlled by synchronous valves to ensure that the flow deviation is ≤5%. A horizontal sensor (accuracy ±0.5°) is installed at the bottom of the carrier plate 102. When the tilt angle exceeds 1°, the hydraulic system automatically stops and issues an alarm. When the first hydraulic rod 207 extends, its output end pushes the U-shaped frame 203 to slide vertically upward along the upright plate 201. The fixed pulley 204 at the top of the U-shaped frame 203 moves upward accordingly. Since the top of the steel cable 205 is fixed to the horizontal plate 202, when the fixed pulley 204 rises, the fixed plate 206 at the bottom of the steel cable 205 is subjected to tension and slides upward along the U-shaped frame 203, thereby driving the carrier plate 102 to rise synchronously. When the first hydraulic rod 207 retracts, the U-shaped frame 203 moves downward, and the carrier plate 102 descends with the fixed plate 206 under the action of gravity.

[0028] In this embodiment, the reset mechanism 9 includes a through groove 901, a slide rod 902 and a reset spring 903. The through groove 901 is opened inside the main support block 7. The slide rod 902 passes through the inside of the through groove 901. Both ends of the slide rod 902 are fixedly connected to the inner wall of the vertical groove 6. The reset spring 903 is provided between the top of the slide rod 902 and the inner top of the through groove 901.

[0029] Local working principle: During the downward movement of the main support block 7, the through groove 901 inside it slides relative to the slide rod 902. The return spring 903 between the top of the slide rod 902 and the top of the through groove 901 is compressed and stores elastic potential energy. When the slider 4 returns to its original position and no longer presses the main support block 7, the return spring 903 releases its elastic force and pushes the main support block 7 to slide upward along the slide rod 902 until the main support block 7 leaves the ground and returns to the initial position at the top of the vertical groove 6.

[0030] In this embodiment, the corner support mechanism 10 includes a fixed rod 1001, a movable rod 1002, a second hydraulic cylinder 1003, a secondary support block 1004, and a rotating assembly. The fixed rod 1001 is located on both sides of the end of the base 1 and slides along the width direction of the base 1. The fixed rods 1001 on both sides of the end of the base 1 are located on different horizontal planes. The horizontal telescopic mechanism 11 controls the fixed rods 1001 to move forward and backward respectively. The movable rod 1002 is hinged to the outer side of the fixed rod 1001. The ends of the fixed rod 1001 and the movable rod 1002 are vertically mounted with the second hydraulic cylinder 1003. The output end of the second hydraulic cylinder 1003 is mounted with the secondary support block 1004. A rotating assembly for driving the movable rod 1002 to rotate horizontally is provided between the end of the base 1 and the movable rod 1002.

[0031] Local working principle: The horizontal telescopic mechanism 11 drives the fixed rod 1001 to slide along the width direction of the base 1. When the fixed rod 1001 moves, the rotating component controls the rotation of the movable rod 1002. When the fixed rod 1001 and the movable rod 1002 reach the preset position, the second hydraulic cylinder 1003 extends and pushes the auxiliary support block 1004 to contact the ground. The anti-slip texture at the bottom of the auxiliary support block 1004 enhances the friction. After the support is completed, the second hydraulic cylinder 1003 retracts and the auxiliary support block 1004 is lifted off the ground.

[0032] In this embodiment, the rotating assembly includes push rod 1005 and rotating rod 1006. Push rod 1005 is hinged to both sides of the end of the base 1. Rotating rod 1006 is rotatably mounted on the top of the movable rod 1002. The ends of the two sets of push rods 1005 are fixedly connected to the rotating rod 1006 respectively.

[0033] Local working principle: When the fixed rod 1001 slides, the push rod 1005 at the end of the base 1 applies torque through the rotating rod 1006, causing the movable rod 1002 to rotate around the hinge point of the fixed rod 1001 (expanding or folding in the horizontal direction).

[0034] In this embodiment, the horizontal telescopic mechanism 11 includes a hollow box 1101, a first gear 1102, a first rack 1103, and a drive assembly. The hollow box 1101 is fixed at the middle position of the end of the base 1. The first gear 1102 is rotatably installed at the middle position inside the hollow box 1101. The top and bottom of the first gear 1102 are horizontally meshed with the first rack 1103. Both sets of first racks 1103 are slidably connected to the hollow box 1101, and the ends of the two sets of first racks 1103 are respectively fixedly connected to the fixed rod 1001. The base 1 is provided with a drive assembly for controlling the rotation of the first gear 1102.

[0035] Local working principle: The drive component drives the first gear 1102 to rotate inside the hollow box 1101. Since the first gear 1102 meshes with the upper and lower sets of first racks 1103, and the two sets of first racks 1103 are respectively connected to the fixing rods 1001 on both sides of the end of the base 1, when the first gear 1102 rotates, the two sets of first racks 1103 slide in opposite directions along the hollow box 1101, so as to realize the synchronous extension or retraction of the fixing rods 1001.

[0036] In this embodiment, the drive assembly includes a first transmission chamber 1104, a first shaft 1105, a second gear 1106, a second rack 1107, a first bevel gear 1108, a second bevel gear 1109, a second shaft 1110, a second transmission chamber 1111, a third gear 1112, a fourth gear 1113, and a third shaft 1114. The first transmission chamber 1104 is located in the middle of the interior of the base 1. The first shaft 1105 is vertically rotatably mounted inside the first transmission chamber 1104. The second gear 1106 is mounted on the top of the first shaft 1105. The second rack 1107 is meshed on both sides of the second gear 1106, and the ends of the second rack 1107 extend... The first shaft 1105 is fixedly connected to the inside of the strip groove 3 and the slider 4. The bottom end of the first shaft 1105 is equipped with a first bevel gear 1108. The two sides of the bottom of the first bevel gear 1108 are symmetrically meshed with second bevel gears 1109. The two ends of the base 1 are provided with second transmission chambers 1111. The ends of the second bevel gears 1109 are all equipped with second shafts 1110 extending into the second transmission chambers 1111. The end of the second shaft 1110 located inside the second transmission chamber 1111 is fixed with a third gear 1112. The top of the third gear 1112 is meshed with a fourth gear 1113. The side of the fourth gear 1113 is installed between the first gear 1102 and the first shaft 1114.

[0037] Local working principle: When the slider 4 moves, the second rack 1107 connected to it drives the second gear 1106 to rotate, causing the first shaft 1105 to rotate in the first transmission chamber 1104. The first bevel gear 1108 at the bottom of the first shaft 1105 rotates synchronously and drives the second bevel gears 1109 meshing on both sides to rotate. The second bevel gear 1109 transmits power to the third gear 1112 in the second transmission chamber 1111 through the second shaft 1110. The third gear 1112 drives the meshing fourth gear 1113 to rotate, and then drives the first gear 1102 to rotate through the third shaft 1114, thus completing the transmission of power from the slider 4 to the horizontal telescopic mechanism 11.

[0038] In this embodiment, through holes are provided between the two sides of the slider 4 to facilitate the passage of the second rack 1107 on another set of sliders 4.

[0039] Local working principle: The perforations on both sides of the slider 4 are used to avoid the second rack 1107 connected to the other set of sliders 4, ensuring that the second rack 1107 does not interfere with each other when the two sets of sliders 4 slide in the strip groove 3, thus ensuring smooth transmission.

[0040] In this embodiment, the return spring 903 is in a compressed state, and the direction of the spring force of the return spring 903 is opposite to the downward movement direction of the main support block 7.

[0041] Local working principle: The return spring 903 is always in a compressed state, and its elastic force is opposite to the downward movement direction of the main support block 7 (i.e., vertically upward), ensuring that the main support block 7 can be quickly pushed to reset when the slider 4 is released from pressure.

[0042] In this embodiment, the secondary support block 1004 is shaped like a frustum, and the bottom end of the secondary support block 1004 has a larger surface area than the top end. The bottom end of the secondary support block 1004 is provided with anti-slip texture.

[0043] Local working principle: The frustum-shaped design makes the bottom surface area of ​​the secondary support block 1004 larger than the top surface area, increasing the contact area with the ground. Combined with the anti-slip texture at the bottom, it improves the stability of the support and prevents slippage.

[0044] Example 3 The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods. In the initial state of the device, the moving wheel 101 is in contact with the ground, which facilitates the overall movement. At this time, the main support block 7 and the auxiliary support block 1004 are both in the reset state (detached from the ground). When the working position is reached, the lifting mechanism 2 is started. The first hydraulic rod 207 extends and pushes the U-shaped frame 203 to move upward. The fixed pulley 204 and the steel cable 205 drive the carrier plate 102 to rise. The guardrail 103 on the edge of the carrier plate 102 rises simultaneously to ensure the safety of the operation.

[0045] During the ascent of the carrier plate 102, the angle of the cross rod 5 increases, pushing the slider 4 to slide along the strip groove 3. The slider 4 presses the main support block 7 to move down along the vertical groove 6. The bottom end of the main support block 7 contacts the ground to bear the central load. The return spring 903 is compressed and stores energy. At the same time, the slider 4 drives the second gear 1106 to rotate through the second rack 1107. The power is transmitted through the first shaft 1105, the bevel gear set (first bevel gear 1108, second bevel gear 1109), the second shaft 1110, the third gear 1112, the fourth gear 1113 and the third shaft 1114, so that the first gear 1102 drives the first rack 1103 to extend and push the fixed rod 1001 to translate.

[0046] When the fixed rod 1001 moves, the push rod 1005 drives the movable rod 1002 to rotate and unfold through the rotating rod 1006. The second hydraulic cylinder 1003 extends so that the auxiliary support block 1004 contacts the ground, forming an external auxiliary support, which works with the main support block 7 to resist the load eccentric moment.

[0047] After the operation is completed, the first hydraulic rod 207 retracts, causing the carrier plate 102 to descend. The cross rod 5 pushes the slider 4 to reset. The main support block 7 moves upward and detaches from the ground under the action of the reset spring 903. The horizontal telescopic mechanism 11 reverses its transmission, the fixed rod 1001 retracts, the movable rod 1002 folds, and the auxiliary support block 1004 retracts and resets with the second hydraulic cylinder 1003. The entire device returns to the moving state and the position is transferred through the moving wheel 101.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed in the present invention, based on the technical solution and concept of the present invention, shall fall within the scope of protection of the present invention.
