Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a safe construction scaffold. Background Technology

[0002] Scaffolding is a working platform erected to ensure the smooth progress of various construction processes. It can be classified according to its location as external scaffolding and internal scaffolding; according to its material as wooden scaffolding, bamboo scaffolding, and steel pipe scaffolding; and according to its structural form as pole-type scaffolding, bridge-type scaffolding, frame-type scaffolding, suspended scaffolding, hanging scaffolding, cantilever scaffolding, and climbing scaffolding.

[0003] A search revealed that prior art CN222227885U discloses a safe construction scaffold, comprising four sets of fixed seats. One set of fixed seats has a rotating mechanism fixedly installed inside. The rotating mechanism has a threaded block threadedly connected to its surface, and a telescopic mechanism is rotatably connected inside the threaded block. Scaffold poles are fixedly installed on the top surface of the fixed seat. This safe construction scaffold, through the telescopic mechanism, allows for automatic deployment when an external power source is connected. A servo motor drives a threaded screw to rotate, causing the threaded block to rise, which in turn extends the telescopic pole. The auxiliary pole also extends, and a sliding block rises within another set of scaffold poles, thus achieving automatic deployment of the scaffold. A positioning block is then inserted into the installation slot, and the positioning bolts are tightened for quick alignment and installation of the top plate. When not in use, the top plate is removed, and the scaffold is retracted, reducing its overall size and facilitating transport.

[0004] However, the above-mentioned scaffolding has the following problems in actual use: there is no protective mechanism at the top, and workers are at risk of falling when moving it, which is not safe. Summary of the Invention

[0005] The purpose of this invention is to provide a safe construction scaffold that solves the problem that existing scaffolds lack protective mechanisms at the top, posing a risk of workers falling during movement and resulting in poor safety.

[0006] To achieve the above objectives, the present invention provides a safe construction scaffold, including a support leg, a top frame fixedly installed on the top of the support leg, and a protective mechanism;

[0007] The protective mechanism includes a U-shaped block, a guide rod, a limiting plate, a sliding sleeve, a protective frame, a hanging ring, and a locking device. The U-shaped block is welded to the top frame. The guide rod passes through the top frame and has the limiting plate integrally installed at one end. The limiting plate is slidably connected to the U-shaped block. The sliding sleeve is slidably mounted on the guide rod. The protective frame is installed on the sliding sleeve. The hanging ring is welded to the protective frame. The locking device is located on the side of the top frame away from the U-shaped block and is used to limit the guide rod.

[0008] The protective frame consists of a main frame and side protection mechanisms. The main frame is fixedly connected to the sliding sleeve. The side protection mechanisms are located on both sides of the main frame.

[0009] The side protection mechanism includes a rotating plate and a limiting device. The rotating plate is rotatably mounted on both sides of the main frame, and the limiting device is mounted on the main frame.

[0010] The limiting device includes a limiting block and a limiting pin. The limiting block is welded to the main frame. The limiting pin passes through the limiting block, the rotating plate and the main frame respectively, and a nut is installed at the end away from its own limiting disc for limiting.

[0011] The locking device includes a locking block and a mating assembly. The locking block is integrally formed with the guide rod and is located at the end of the guide rod away from the limiting plate. The mating assembly is disposed on the top frame near the locking block.

[0012] The mating components include ear plates and connectors. The ear plates are welded to the top frame and are vertically symmetrically arranged on both sides of the locking block. The connectors are arranged between the ear plates and pass through the locking block.

[0013] The safe construction scaffold also includes an anti-slip mechanism, which includes an anti-slip plate and an anti-slip component. The anti-slip plate is installed on a detachable standing board on the top of the top frame, and the anti-slip component is located on top of the anti-slip plate.

[0014] This invention provides a safe construction scaffold. During construction, workers can stand on a detachable standing board at the top of the scaffold and be inside the protective frame. The high-altitude work safety belts worn by the workers are connected to the hanging rings via connecting straps of appropriate length. When the workers move, the protective frame moves simultaneously. The protective frame directly forms a protective structure outside the workers, improving construction safety. This solves the problem of existing scaffolds lacking a protective mechanism at the top, resulting in the risk of workers falling during movement and poor safety. Attached Figure Description

Detailed Implementation

[0022] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0023] Example 1:

[0024] like Figures 1 to 3 As shown, where Figure 1 This is a schematic diagram of the overall structure of a safe construction scaffold. Figure 2 This is a schematic diagram of the ear plate structure. Figure 3 This is a structural schematic diagram of a side protection mechanism. The present invention provides a safe construction scaffold, including a support leg 101, a top frame 102, and a protective mechanism. The protective mechanism includes a U-shaped block 104, a guide rod 105, a limiting plate 106, a sliding sleeve 107, a protective frame 108, a hanging ring 109, and a locking device. The locking device includes a locking block 110 and a mating assembly, which includes an ear plate 111 and a connector 112. This solution solves the problem that existing scaffolds lack a top protective mechanism, posing a risk of falls for workers during movement and resulting in poor safety. It is understood that this solution can improve the safety of construction operations.

[0025] In this embodiment, a top frame 102 is fixedly installed on the top of the support leg 101. A detachable standing plate 103 is fixed on the top frame 102 by positioning pins and bolts arranged from bottom to top. In actual use, the bolted components need to be checked for looseness periodically.

[0026] The U-shaped block 104 is welded to the top frame 102. The guide rod 105 passes through the top frame 102 and has a limiting plate 106 integrally installed at one end. The limiting plate 106 is slidably connected to the U-shaped block 104. The sliding sleeve 107 is slidably mounted on the guide rod 105. The protective frame 108 is installed on the sliding sleeve 107. The hanging ring 109 is welded to the protective frame 108. The locking device is located on the side of the top frame 102 away from the U-shaped block 104 to limit the guide rod 105. The U-shaped block 104 is used to limit the limiting plate 106 and prevent the guide rod 105 from rotating after installation. A straight guide ridge is provided on the rear side of the guide rod 105. The guide ridge slides in cooperation with the sliding groove inside the sliding sleeve 107. All detachable parts can be replaced after wear. The protective frame 108 is connected to the sliding sleeve 107 by positioning pins and bolts. The hanging ring 109 and the auxiliary connecting belt work together to connect with the high-altitude work safety belt worn by the construction personnel. The length of the auxiliary connecting belt must ensure that the construction personnel have room to move inside the protective frame 108. At the same time, the protective frame 108 can move together when the construction personnel move.

[0027] Secondly, the main frame 1081 is fixedly connected to the sliding sleeve 107; the side protection mechanism 1082 is disposed on both sides of the main frame 1081. The main frame 1081 is a protective frame structure formed by welding multiple rectangular plates. The side protection mechanism 1082 is used for protective coordination.

[0028] Then, the rotating plate 10821 is rotatably mounted on both sides of the main frame 1081; the limiting device is mounted on the main frame 1081. One end of the rotating plate 10821 is mounted on the main frame 1081 by a rotating pin, and a through hole is provided on the other end. The main frame 1081 and the limiting block 10822 are provided with alignment through holes.

[0029] Furthermore, the limiting block 10822 is welded to the main frame 1081; the limiting pin 10823 passes through the limiting block 10822, the rotating plate 10821, and the main frame 1081 respectively, and a nut is installed at the end away from its own limiting disc for limiting. The top of the limiting block 10822 is open, and the bottom is not through, so as to limit the end of the rotating plate 10821. The limiting pin 10823 is T-shaped and passes directly through the through holes on the limiting block 10822, the rotating plate 10821, and the main frame 1081 during installation, and finally a nut is installed for limiting.

[0030] Furthermore, the locking block 110 is integrally formed with the guide rod 105 and is located at the end of the guide rod 105 away from the limiting plate 106; the mating assembly is disposed on the top frame 102 near the locking block 110. A vertical through hole is provided on the locking block 110, which aligns with the through hole on the ear plate 111.

[0031] Finally, the ear plates 111 are welded to the top frame 102 and vertically symmetrically arranged on both sides of the locking block 110; the connecting piece 112 is arranged between the ear plates 111 and passes through the locking block 110. The connecting piece 112 adopts a T-shaped screw and nut structure, and the nut is spot-welded to the T-shaped screw after installation. During subsequent disassembly, the screw can be cut off with a cutting machine to replace components such as the guide rod 105.

[0032] When using this invention to address the problem of existing scaffolding lacking a protective mechanism at the top, posing a risk of falls and poor safety for workers during movement, construction workers can stand on the detachable standing plate 103 at the top of the top frame 102, inside the protective frame 108. The worker's high-altitude work safety belt is then connected to the hanging ring 109 via a connecting strap of appropriate length. When the worker moves, the protective frame 108 moves simultaneously, directly forming a protective structure outside the worker's body, improving construction safety and thus solving the problem of existing scaffolding lacking a protective mechanism at the top, posing a risk of falls and poor safety for workers during movement.

[0033] Example 2:

[0034] like Figure 4 As shown, where Figure 4 This is a schematic diagram of the installation position of the anti-slip plate. Based on the first embodiment, the present invention provides a safe construction scaffold, which further includes an anti-slip mechanism, comprising an anti-slip plate 201 and an anti-slip component 202.

[0035] The anti-slip plate 201 is mounted on the detachable standing plate 103 at the top of the top frame 102; the anti-slip component 202 is disposed on the top of the anti-slip plate 201. The anti-slip plate 201 can be fixed to the standing plate 103 with bolts, and the bolts are checked for looseness periodically. The anti-slip component 202 has anti-slip protrusions of a corresponding shape and is integrally disposed on the anti-slip plate 201.

[0036] In this embodiment, the anti-slip plate 201 and the anti-slip component 202 structure can improve the safety of construction workers moving around the scaffold during construction.

[0037] Example 3:

[0038] like Figure 5 As shown, where Figure 5 This is a schematic diagram of the overall structure of a safe construction scaffold. Based on the first embodiment, the present invention provides a safe construction scaffold, which further includes a stabilizing mechanism, comprising an upper locking block 301, a horizontal plate 302, and a lower locking block 303.

[0039] The upper locking block 301 is slidably connected to the crossbar on the support leg 101. The cross plate 302 is welded to the top of the two upper locking blocks 301. The lower locking block 303 is slidably connected to the crossbar on the support leg 101 and is detachably connected to the upper locking blocks 301. The lower locking block 303 can be connected to the upper locking block 301 by bolts.

[0040] In this embodiment, the structure of the upper locking block 301, the horizontal plate 302 and the lower locking block 303 can improve the stability of the support leg 101 during operation, and the position or number of the structure can be set as needed.

[0041] The above-disclosed embodiments are merely one or more preferred embodiments of this application and should not be construed as limiting the scope of this application. Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
