Description

Technical Field

[0001] This utility model belongs to the field of scaffolding technology, and in particular relates to an attached lifting scaffolding. Background Technology

[0002] In the field of construction equipment technology, attached lifting scaffolding, also known as climbing scaffolding in the industry, is a support structure erected on construction sites to facilitate workers' operations and solve vertical transportation problems. It is a new type of scaffolding system developed in recent years, mainly used in high-rise shear wall buildings, and can climb or descend along the building.

[0003] For example, patent CN213927417U discloses an attached lifting scaffold, relating to the field of lifting scaffold technology. The attached lifting scaffold includes a frame body and a lifting and hanging assembly. The lifting and hanging assembly includes wall-mounted hangers and a horizontal truss, an upper lifting point assembly, and a lower lifting point assembly mounted on the frame body. Both the upper and lower lifting point assemblies include lifting point trusses, which are positioned between the guide rail uprights and the horizontal truss of the frame body and are fixedly connected to both. The lifting point trusses may include lifting point truss uprights at their outer ends, and the horizontal truss includes vertical frame edges at its outer ends. The lifting point truss uprights are parallel and fitted to the guide rail uprights and vertical frame edges, respectively. This utility model's attached lifting scaffold has a reasonable structure, is not easily deformed, and has good safety performance.

[0004] Existing attached lifting scaffolding suffers from reduced stability due to its heavy weight, making it prone to tilting and potential collapse. Therefore, we propose an attached lifting scaffolding system. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing an attached lifting scaffold that avoids the problem of scaffolding easily tilting.

[0006] In view of this, the present invention provides an attached lifting scaffold, including an outer upright, an inner upright on one side of the outer upright, a support frame fixedly connected to the connection between the inner and outer uprights, a bottom support rod fixedly connected to the top of the support frame, a footboard fixedly connected above the bottom support rod, a connecting flap hinged to the outer wall of the footboard, a guide rail fixedly connected to the outer wall of the inner upright, a protective rod fixedly connected to the outer wall of the guide rail, a wall-mounted support on one side of the guide rail, a limiting block fixedly connected to the outer wall of the wall-mounted support and fitting into the outer wall of the guide rail, a spring fixedly connected to the inner wall of the wall-mounted support, a base plate fixedly connected to one end of the spring, a telescopic rod slidably connected to the inner wall of the wall-mounted support and fixedly connected to the outer wall of the base plate, and an anti-fall block fixedly connected to one end of the telescopic rod.

[0007] Based on the above structure, the spring drives the telescopic rod on the outer wall of the base plate to slide horizontally along the inner wall of the wall-mounted support through its own elastic force. The sliding of the telescopic rod causes the anti-fall block to slide to the bottom of the protective rod on the outer wall of the guide rail, thereby supporting the guide rail and preventing the scaffold from falling.

[0008] Preferably, the protective rods are evenly distributed along the outer wall of the guide rail, and two sets of limiting blocks are provided. The limiting blocks are C-shaped. The anti-fall blocks form a telescopic structure with the wall-mounted support through springs and telescopic rods. The anti-fall blocks are inverted trapezoidal in shape. In this embodiment, by providing two sets of C-shaped limiting blocks, it is beneficial for the guide rail to slide stably along the outer wall of the limiting blocks, preventing the guide rail from falling off. The inverted trapezoidal anti-fall blocks are beneficial for the guide rail to be lifted smoothly. At the same time, the anti-fall blocks effectively support the protective rods on the outer wall of the guide rail.

[0009] Preferably, the support frame at the connection between the outer and inner uprights is triangular in shape, and the support frame at the connection between the outer upright and the guide rail is Z-shaped. In this embodiment, by setting the triangular support frame, the stability of the connection between the outer and inner uprights is improved, and by setting the Z-shaped support frame, the guide rail is supported when it is lifted, thus preventing the overall scaffolding from deforming.

[0010] Preferably, a lifting bracket is provided on one side of the inner upright, and a middle hanging assembly is embedded in the outer wall of the lifting bracket. An upper hanging point truss is provided above the middle hanging assembly and is fixedly connected to the outer wall of the inner upright. An electric hoist is provided below the middle hanging assembly. A gravity sensor is installed at the bottom of the electric hoist, and a lower hanging point truss is fixedly connected to the bottom of the gravity sensor and is fixedly connected to the outer wall of the inner upright. In this embodiment, the electric hoist can lift the scaffold by driving the guide rail of the lower hanging point truss to slide vertically along the outer wall of the limiting block through the middle hanging assembly on the outer wall of the lifting bracket.

[0011] Preferably, the outer wall of the outer upright is provided with a protective net, the top of the outer and inner uprights are fixedly connected with tie rods, the outer walls of the outer and inner uprights are fixedly connected with horizontal support trusses, the outer walls of the guide rail and the inner upright are both equipped with connectors, the outer walls of the connectors are hinged with tie rods, the bottom end of the tie rod is provided with a pre-embedded frame, the inner wall of the pre-embedded frame is provided with a screw, the outer wall of the screw is threadedly connected with a tie slider that is hinged to the bottom end of the tie rod. In this embodiment, after the scaffold is lifted into place, the cantilever at the top of the scaffold needs to be temporarily tied to ensure the stability of the scaffold. The worker rotates the screw, and the rotation of the screw drives the tie slider to slide horizontally through the thread. The sliding of the tie slider supports the guide rail and the inner upright on one side of the connector through the tie rod, preventing the guide rail and the inner upright from deforming.

[0012] Preferably, the protective netting is arranged in a star-shaped pattern, and the tie rods are inclined. In this embodiment, by setting the protective netting in a star-shaped pattern, it is beneficial to improve the overall protection of the scaffolding and prevent the protective netting from falling off. By setting the tie rods in an inclined shape, it is beneficial to improve the structural strength of the top of the outer and inner uprights.

[0013] Preferably, the guide rail and inner upright are connected to the wall to form a support structure through a tie slider and a tie rod. In this embodiment, the tie slider slides through the tie rod to support the guide rail and inner upright on one side of the connector, thereby preventing the guide rail and inner upright from deforming.

[0014] The beneficial effects of this utility model are:

[0015] 1. This attached lifting scaffold, by setting up anti-fall blocks, uses an electric hoist to lift the scaffold by driving the guide rail on the outer wall of the lower suspension point truss to slide vertically along the outer wall of the limit block through the middle hanging component on the outer wall of the lifting bracket. At the same time, the spring drives the telescopic rod on the outer wall of the base plate to slide horizontally along the inner wall of the wall-mounted support through its own elastic force. The sliding of the telescopic rod causes the anti-fall block to slide to the lower part of the protective rod on the outer wall of the guide rail, thereby supporting the guide rail and preventing the scaffold from falling.

[0016] 2. This attached lifting scaffold, by setting up tie rods, requires temporary tying of the cantilever at the top of the scaffold after it is raised to the correct position, thereby ensuring the stability of the scaffold. Workers rotate the screw, and the rotation of the screw drives the tie slider to slide horizontally through the thread. The sliding tie slider supports the guide rail and inner upright on one side of the connector through the tie rod, preventing the scaffold from slipping. Attached Figure Description

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 - Figure 4 This application will be described in further detail.

[0024] In this application, the terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "middle," "vertical," and "horizontal," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. These terms are primarily for the purpose of better describing this application and its embodiments, and are not intended to limit the indicated device, element, or component to having a specific orientation, or to be constructed and operated in a specific orientation.

[0025] This application discloses an attached lifting scaffold, including an outer upright 1, an inner upright 2 on one side of the outer upright 1, a support frame 3 fixedly connected to the connection between the inner upright 2 and the outer upright 1, a bottom support rod 4 fixedly connected to the top of the support frame 3, a footboard 5 fixedly connected above the bottom support rod 4, a connecting flap 6 hinged to the outer wall of the footboard 5, a guide rail 7 fixedly connected to the outer wall of the inner upright 2, a protective rod 8 fixedly connected to the outer wall of the guide rail 7, a wall-mounted support 9 on one side of the guide rail 7, a limiting block 10 fixedly connected to the outer wall of the wall-mounted support 9 and fitting into the outer wall of the guide rail 7, a spring 11 fixedly connected to the inner wall of the wall-mounted support 9, a base plate 12 fixedly connected to one end of the spring 11, a telescopic rod 13 slidably connected to the inner wall of the wall-mounted support 9 fixedly connected to the outer wall of the base plate 12, and an anti-fall block 14 fixedly connected to one end of the telescopic rod 13.

[0026] Based on the above structure, the spring 11 drives the telescopic rod 13 on the outer wall of the base plate 12 to slide horizontally along the inner wall of the wall-mounted support 9 through its own elastic force. The sliding of the telescopic rod 13 drives the anti-fall block 14 to slide below the protective rod 8 on the outer wall of the guide rail 7, thereby supporting the guide rail 7 and preventing the scaffold from falling.

[0027] In one embodiment, the protective rods 8 are equidistantly distributed along the outer wall of the guide rail 7, and two sets of limiting blocks 10 are provided. The limiting blocks 10 are in the shape of a "C". The anti-fall block 14 forms a telescopic structure with the wall support 9 through the spring 11 and the telescopic rod 13. The anti-fall block 14 is in the shape of an inverted trapezoid.

[0028] In this embodiment, by setting two sets of "C"-shaped limiting blocks 10, the guide rail 7 can slide stably along the outer wall of the limiting block 10, preventing the guide rail 7 from falling off. The inverted trapezoidal anti-fall block 14 helps the guide rail 7 to be lifted smoothly. At the same time, the anti-fall block 14 effectively supports the protective rod 8 on the outer wall of the guide rail 7.

[0029] In one embodiment, the support frame 3 at the connection between the outer upright 1 and the inner upright 2 is triangular in shape, and the support frame 3 at the connection between the outer upright 1 and the guide rail 7 is Z-shaped.

[0030] In this embodiment, by setting a triangular support frame 3, the stability of the connection between the outer upright 1 and the inner upright 2 is improved. By setting a "Z"-shaped support frame 3, the guide rail 7 is supported when it is lifted, thus preventing the overall scaffolding from deforming.

[0031] In one embodiment, a lifting bracket 15 is provided on one side of the inner upright 2. A middle hanging component 1501 is fitted into the outer wall of the lifting bracket 15. An upper hanging point truss 16 fixedly connected to the outer wall of the inner upright 2 is provided above the middle hanging component 1501. An electric hoist 17 is provided below the middle hanging component 1501. A gravity sensor 18 is installed at the bottom of the electric hoist 17. A lower hanging point truss 19 fixedly connected to the bottom of the gravity sensor 18 is fixedly connected to the outer wall of the inner upright 2.

[0032] In this embodiment, to facilitate the operation of the electric hoist 17, the middle hanging component 1501 on the outer wall of the lifting bracket 15 drives the guide rail 7 on the outer wall of the lower hanging point truss 19 to slide vertically along the outer wall of the limiting block 10, thereby lifting the scaffold.

[0033] In one embodiment, a protective net 20 is provided on the outer wall of the outer pole 1, and a tie rod 21 is fixedly connected to the top of the outer pole 1 and the inner pole 2. A horizontal support truss 22 is fixedly connected to the outer walls of both the outer pole 1 and the inner pole 2. A connector 23 is installed on the outer wall of both the guide rail 7 and the inner pole 2. A tie rod 24 is hinged to the outer wall of the connector 23. A pre-embedded frame 25 is provided at the bottom of the tie rod 24. A screw 26 is provided on the inner wall of the pre-embedded frame 25. A tie slider 27 that is hinged to the bottom of the tie rod 24 is threadedly connected to the outer wall of the screw 26.

[0034] In this embodiment, after the scaffolding is raised to the position, it is necessary to temporarily tie the cantilever at the top of the scaffolding to ensure the stability of the scaffolding. The workers rotate the screw 26, and the rotation of the screw 26 drives the tie slider 27 to slide horizontally through the thread. The tie slider 27 slides through the tie rod 24 to support the guide rail 7 and the inner upright 2 on one side of the connector 23, so as to prevent the scaffolding from slipping.

[0035] In one embodiment, the protective netting 20 is arranged in a star-shaped pattern, and the tie rods 21 are inclined.

[0036] In this embodiment, by setting up a protective netting 20 in a star-shaped distribution, it is beneficial to improve the overall protection of the scaffolding and prevent the protective netting 20 from falling off. By setting up inclined tie rods 21, it is beneficial to improve the structural strength of the top of the outer upright 1 and the inner upright 2.

[0037] In one embodiment, the guide rail 7 and the inner upright 2 form a support structure with the wall through the connecting slider 27 and the connecting rod 24.

[0038] In this embodiment, the tie slider 27 slides through the tie rod 24 to support the guide rail 7 and inner upright rod 2 on one side of the connector 23, so as to prevent the guide rail 7 and inner upright rod 2 from deforming.

[0039] In this embodiment, the attached lifting scaffold is first installed on the construction wall. Then, the electric hoist 17 lifts the scaffold by moving the guide rail 7 on the outer wall of the lower suspension point truss 19 vertically along the outer wall of the limiting block 10 through the middle hanging component 1501 on the outer wall of the lifting bracket 15. At the same time, the spring 11 moves the telescopic rod 13 on the outer wall of the base plate 12 horizontally along the inner wall of the wall-mounted support 9 through its own elasticity. The telescopic rod 13 moves the anti-fall block 14 to slide below the protective rod 8 on the outer wall of the guide rail 7, thereby supporting the guide rail 7 and preventing the scaffold from falling.

[0040] Finally, after the scaffolding is raised to its position, temporary bracing is required for the cantilever at the top of the scaffolding to ensure its stability. Workers rotate screw 26, which drives the bracing slider 27 to slide horizontally through the thread. The bracing slider 27 slides through the bracing rod 24 to support the guide rail 7 and inner upright 2 on one side of the connector 23, preventing the scaffolding from slipping.
