Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, and in particular to a guide rail-attached aerial work platform that can move horizontally and vertically in both directions. Background Technology

[0002] In recent years, with the continuous advancement of urbanization in my country, the number of high-rise and super high-rise buildings has been increasing, and high-altitude operations on exterior walls, such as curtain wall installation, insulation construction, and exterior wall decoration, have become very common. Choosing the appropriate method for high-altitude exterior wall operations is crucial to ensuring construction safety and efficiency. Suspended platforms are currently the most widely used type of high-altitude work machinery. While they offer advantages such as low cost and convenient installation and dismantling, the high-altitude nature of suspended platform operations means they are prone to malfunctions such as safety lock failure, platform breakage, and wire rope breakage, leading to safety accidents. Because suspended platforms are suspended at high altitudes by wire ropes, they often experience severe swaying due to operator movement and strong winds, causing fear among workers and increasing operational errors, thus indirectly increasing the risk of accidents. Furthermore, since suspended platforms are vertical lifting construction machinery, a single platform can only be used for a relatively small range of vertical lifting operations on exterior walls. To complete high-altitude exterior wall operations for a single building, multiple platforms often need to be erected simultaneously. The erection process is complex and poses certain safety hazards, reducing construction efficiency and extending the construction period. Summary of the Invention

[0003] To address the aforementioned problems, this invention provides a safer, horizontally and vertically movable guide rail-attached aerial work platform. This platform can move in both horizontal and vertical directions, and a single machine can meet the needs of curtain wall installation, insulation construction, and high-altitude work on exterior walls for all parts of the building's exterior.

[0004] The technical solution adopted in this invention:

[0005] A guide rail-attached aerial work platform capable of horizontal and vertical bidirectional movement includes a work platform, two movable lattice columns, four attachment leg assemblies, a guide rail assembly, a rail assembly, and two fixed connecting frames. The guide rail assembly is horizontally mounted on the outer surface of the completed building structure. The rail assembly is mounted on the ground outside the building structure components. Two movable lattice columns are movably connected to the rail assembly. Each movable lattice column is equipped with an attachment leg assembly. The attachment leg assemblies connected to the same movable lattice column are arranged in a figure-eight pattern. The other end of the attachment leg assembly is slidably connected to the guide rail assembly. A fixed connecting frame is welded to each end of the work platform. The work platform is movably connected to the movable lattice columns through the fixed connecting frames, enabling the work platform to move vertically up and down.

[0006] The standard section of the movable lattice column includes two spaced-apart circular tube guide columns, which are fixedly connected by a connecting rod. A steel rack is fixedly installed on the movable lattice column, and the steel rack is continuously installed from bottom to top in the vertical direction.

[0007] The movable lattice column is fixed at the bottom with a column steel support. The two column steel supports are connected by a support connecting truss. A traction device is installed inside the column steel support. The traction device is connected to a steel track wheel assembly installed at the bottom of the column steel support.

[0008] The attached leg assembly includes a slider and a steel pipe truss attachment arm. One end of the steel pipe truss attachment arm is welded to a movable lattice column, and the other end is welded to the slider. The slider is slidably connected to the guide rail assembly.

[0009] The guide rail assembly includes a steel guide rail and mounting bolts. The steel guide rail is horizontally arranged on the outer surface of the completed building structure. The steel guide rail is fastened to the outer surface of the completed building structure by the mounting bolts. The slider slides on the steel guide rail along the guide rail arrangement direction.

[0010] The work platform includes a bottom steel plate and a work platform railing, as well as small work platform beams arranged parallel and equidistantly on the bottom of the bottom steel plate. The work platform railings are vertically installed around the bottom steel plate, and the small work platform beams are welded to a fixed connecting frame.

[0011] The fixed connection frame includes a motor, guide wheels, a "U"-shaped subframe, a steel main beam, a motor gear assembly, and guide wheel supports. The steel main beam is welded to the working platform beam. A motor is installed at each end of the steel main beam, driving the electric gear to rotate. The motor gear assembly meshes with the steel rack. Both ends of the steel main beam are equipped with "U"-shaped subframes. Each "U"-shaped subframe has four sets of guide wheels and guide wheel supports. The guide wheel supports are welded and fixed to the end of the "U"-shaped subframe. The guide wheels are connected to the guide wheel supports and can rotate freely around the wheel axle of the guide wheel support. The axes of the two guide wheels at the same end of the "U"-shaped subframe are perpendicular to each other, and both guide wheels can roll vertically along the circular tube guide column.

[0012] The rail assembly includes several sleepers and two rails. The sleepers are arranged in parallel at equal intervals, and the two rails are arranged in parallel above them in a direction perpendicular to the sleepers. A steel rail wheel assembly is arranged on the rails and can roll on the rails.

[0013] The beneficial effects of this invention are as follows: The aerial work platform of this invention can meet the needs of high-altitude operations on building facades, such as curtain wall installation, insulation construction, and exterior wall decoration. The height of the movable lattice columns and the length of the rails and guide rails can be adjusted according to the size of the area requiring high-altitude operations on the building facade. This allows the work platform to reach the entire height of the building facade vertically and the entire length of the building facade horizontally, covering the entire building facade. This avoids the cumbersome process of installing and dismantling multiple suspended platforms, thus improving construction efficiency. Furthermore, this invention avoids the installation, dismantling, and use of suspended platforms, preventing safety accidents caused by malfunctions such as safety lock failure, platform breakage, and wire rope breakage. This invention reduces severe swaying caused by the basket being suspended high in the air, coupled with factors such as personnel operation and strong winds, thereby reducing the fear of operators in the basket and indirectly avoiding many operational errors, thus reducing potential safety hazards at the source. The movable lattice column of this invention is assembled from standard unit sections, and the rails, guide rails, and attached legs can all be transported to the site in sections for quick assembly, convenient erection, and a sturdy finished product, reducing construction steps and simplifying the construction process.

Detailed Implementation

[0020] A horizontally and vertically movable guide rail-attached aerial work platform includes a work platform 1, two movable lattice columns 2, four attachment leg assemblies 3, a guide rail assembly 4, a rail assembly 5, and two fixed connecting frames 6. The guide rail assembly 4 is horizontally set on the outer surface of the completed building structure. The rail assembly 5 is set on the ground outside the building structure components. Two movable lattice columns 2 are movably connected to the rail assembly 5. Two attachment leg assemblies 3 are arranged on each movable lattice column 2. The two attachment leg assemblies 3 connected to the same movable lattice column 2 are arranged in a "V" shape. One end of the attachment leg assembly 3 is welded to two circular tube guide columns 23 of the movable lattice column 2 near the building structure. The other end of component 3 is slidably connected to the guide rail component 4. If the height of the movable lattice column 2 increases, the number of attachment leg components 3 can be increased at a certain interval in the vertical direction according to actual needs to ensure the stability of the movable lattice column 2 during movement and work. A fixed connecting frame 6 is welded to each end of the work platform 1. The work platform 1 is movably connected to the movable lattice column 2 through the fixed connecting frame 6, so that the work platform 1 can move up and down in the vertical direction. The movable lattice column 2 rolls on the rail component 5, and the attachment leg components 3 on the movable lattice column 2 slide on the guide rail component 4, driving the entire work platform 1 to move in the horizontal direction, thereby realizing the movement of the aerial work platform in both the horizontal and vertical directions.

[0021] The standard section of the movable lattice column 2 includes two spaced-apart circular tube guide columns 23, which are fixedly connected by a connecting rod. A steel rack 24 is fixedly installed on the movable lattice column 2. The steel rack 24 is continuously installed from bottom to top in the vertical direction. The steel rack 24 meshes with the motor gear assembly 65 on the outside of the motor 61, thereby driving the working platform 1 to climb up and down along the steel rack 24.

[0022] The bottom of the movable lattice column 2 is fixed with a column steel support 21. The two column steel supports 21 are connected by a support connecting truss 211. The support connecting truss 211 can keep the distance between the two column steel supports 21 unchanged during movement and use. A traction device is provided inside the column steel support 21. The traction device is connected to a steel rail wheel assembly 22 set at the bottom of the column steel support 21. The steel rail wheel assembly 22 includes a steel wheel 221, a wheel axle 222 and a wheel brake 223. The steel wheel 221 and the wheel brake 223 are connected to the wheel axle 222. The steel wheel 221 is arranged on the rail 52 and rolls on the rail 52. When the two movable lattice columns 2 and the column steel supports 21 move to a certain position, the two movable lattice columns 2 and the column steel supports 21 can be fixed in that position by the wheel brake 223.

[0023] The attached leg assembly 3 includes a slider 31 and a steel pipe truss attached arm 32. One end of the steel pipe truss attached arm 32 is welded to the movable lattice column 2, and the other end is welded to the slider 31. The slider 31 is slidably connected to the guide rail assembly 4. The attached leg assembly 3 is set between the movable lattice column 2 and the completed building structure. Two attached leg assemblies 3 are arranged on each movable lattice column 2. One end of the attached leg assembly 3 is welded to two round tube guide columns 23 near the building structure of the movable lattice column 2, and the other end of the attached leg assembly 3 slides on the guide rail assembly 4 through the slider 31.

[0024] The guide rail assembly 4 includes a steel guide rail 41 and mounting bolts 42. The steel guide rail 41 is horizontally arranged on the outer surface of the completed building structure. The steel guide rail 41 is fastened to the outer surface of the completed building structure by the mounting bolts 42. The slider 31 slides on the steel guide rail 41 along the guide rail arrangement direction. The length of the steel guide rail 41 is determined according to the range of the aerial work platform to be arranged. If the height of the movable lattice column 2 increases, the number of guide rail assemblies 4 can be increased vertically at a certain interval according to actual needs, as the number of support leg assemblies 3 increases.

[0025] The work platform 1 includes a bottom steel plate 13 and a work platform railing 12, as well as four work platform beams 11 arranged parallel and equidistantly at the bottom of the bottom steel plate 13. The work platform railing 12 is vertically installed around the bottom steel plate 13, and the work platform beams 11 are welded to the fixed connecting frame 6.

[0026] The fixed connecting frame 6 includes a motor 61, guide wheels 62, a U-shaped bracket 63, a steel main beam 64, a motor gear assembly 65, and guide wheel supports 66. The steel main beam 64 is welded to the working platform beam 11. A motor 61 is installed at each end of the steel main beam 64, driving the motor gear assembly 65 to rotate. The motor gear assembly 65 meshes with a steel rack 24. Each end of the steel main beam 64 has a U-shaped bracket 63. Each U-shaped bracket 63 has four sets of guide wheels 62 and guide wheel supports 66. The guide wheel supports 66 are welded and fixed to the end of the U-shaped bracket 63. The guide wheels 62 are connected to the guide wheel supports 66 and can move along the guide wheel supports 66. The shaft rotates freely around the center, and each end is equipped with four sets of guide wheels 62 and guide wheel supports 66. The axes of the two guide wheels 62 at the same end of the "U"-shaped bracket 63 are perpendicular to each other. The guide wheels 62 can roll along the circular tube guide column 23 in the vertical direction. The motor gear assembly 65 includes a motor gear 651 and a gear brake 652 mounted on the motor gear 651. When the motor 61 is turned on, the motor gear 651 moves on the steel rack 24. The working platform beam 11 at the bottom of the working platform 1 is welded to the fixed connecting frame 6, which can drive the working platform 1 to move up and down in the vertical direction. When it reaches a certain position, the up and down movement of the working platform can be stopped by the gear brake 652, so that the construction platform is fixed in the vertical direction.

[0027] The rail assembly 5 includes several sleepers 51 and two rails 52. The sleepers 51 are arranged in parallel at equal intervals, and the two rails 52 are arranged in parallel above the sleepers 51 in a direction perpendicular to the sleepers 51. The steel rail wheel assembly 22 is arranged on the rails 52 and can roll on the rails 52. The length of the rails 52 and the number of sleepers 51 are determined according to the range of the aerial work platform to be arranged.

[0028] Example 1

[0029] This example addresses common safety accidents caused by suspended platforms due to malfunctions such as safety lock failure, platform breakage, and wire rope breakage. It reduces safety hazards arising from severe platform swaying caused by factors like personnel operation and strong winds, and overcomes the limitations of suspended platforms that can only be raised and lowered vertically, resulting in a limited working range. A guide rail-attached aerial work platform capable of bidirectional horizontal and vertical movement is proposed. This platform can be erected on-site for high-altitude exterior wall operations such as curtain wall installation, insulation construction, and exterior wall decoration. Figure 1The construction machinery shown allows the working platform 1 to move vertically along the steel rack 24 on the movable lattice column 2. When it reaches a certain position, the gear brake 652 stops the vertical movement of the working platform 1, fixing it in place vertically. Horizontally, the two movable lattice columns 2 can move synchronously on the rail 52 under the drive of the steel rail wheel assembly 22 connected to the column steel support 21. When the two movable lattice columns 2 and their steel support 21 reach a certain position, the wheel brake 223 fixes them in place. During horizontal movement, the slider 31 at the end of the steel pipe truss attachment arm 32 connected to the movable lattice column 2 slides on the steel guide rail 41, enabling the horizontal movement of the construction platform. With sufficiently long rails 52 and 41, and two sufficiently high movable lattice columns 2, the working platform 1 can cover the entire building facade, allowing workers on it to perform high-altitude exterior wall work such as curtain wall installation, insulation, and exterior decoration without any blind spots. This horizontally and vertically movable rail-attached aerial work platform can meet the needs of all parts of the building facade for curtain wall installation, insulation, and exterior decoration, while also improving the safety of high-altitude operations. Furthermore, this invention reduces severe swaying caused by the basket being suspended at high altitudes, coupled with personnel operation and strong winds, reducing the fear of operators in the basket and indirectly avoiding many operational errors, thus reducing potential safety hazards at the source.
