Description

Technical Field

[0001] This utility model relates to the field of anti-fall technology for lifting scaffolds, and in particular to an attached anti-fall device for lifting scaffolds. Background Technology

[0002] Attached lifting scaffolding is a type of scaffolding erected along the outer surface of a building structure. It is a new scaffolding technology that rapidly developed at the beginning of this century. It transforms high-altitude work into low-altitude work and suspended work into work within the scaffold structure, offering significant advantages such as low carbon footprint, high-tech content, and greater economy, safety, and convenience. The lifting function of lifting scaffolding greatly facilitates construction and decoration work. Lifting scaffolding also features fall protection devices, ensuring it remains in a safe state and effectively preventing falls, which is crucial for safe construction.

[0003] A search revealed a Chinese patent application with patent number CN202223425855.8, which discloses an attached lifting scaffold fall arresting device. This device lowers rapidly along a guide rail with a horizontal bar. Before the fall arresting wheel can reset, the horizontal bar presses down on the second fall arresting lever. At this point, a positioning block prevents the fall arresting wheel from rotating further, thus locking the horizontal bar and stopping the guide rail from falling, preventing accidents or losses. Compared to using elastic elements for limiting the movement, this method improves fall arresting stability. However, this technical solution requires the cooperation of two fall arresting levers, a fall arresting wheel, and a counterweight to stop the attached lifting scaffold from slipping down one side, resulting in a complex and unreliable fall arresting mechanism. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an attached lifting scaffold fall prevention device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An attached lifting scaffold fall prevention device includes a fixed base. A set of support plates is fixed to the outer wall of one side of the fixed base. A locking fall prevention block is rotatably connected to the inner wall of one side of the support plates via a rotating rod. A baffle is fixed to the outer wall of the opposite side of the support plates. There is a gap between the baffle and the top of the locking fall prevention block. The bottom outer wall of the locking fall prevention block has a first inclined surface, a second inclined surface, a third inclined surface, and a fourth inclined surface, respectively. The length of the first inclined surface is 59.03 mm, the length of the second inclined surface is 29.37 mm, the length of the third inclined surface is 38.64 mm, and the length of the fourth inclined surface is 33.22 mm.

[0006] As a further improvement of this utility model: the length of the anti-fall block is 133mm and the width is 35mm, and the outer wall of the anti-fall block has an insertion hole.

[0007] As a further embodiment of this utility model: a support frame is fixed to the outer wall of the support plate, and a set of guide pulleys is rotatably connected to the inner wall of the support frame.

[0008] As a further improvement of this utility model: the outer wall of the support frame has a guide hole, and the attached lifting scaffold body is slidably connected to the inner wall of the guide hole.

[0009] As a further embodiment of this utility model: a bottom sleeve is rotatably connected to one side of the outer wall of the support plate, and an adjusting screw is threadedly connected to the inner wall of the bottom sleeve, with a top head fixed at one end of the adjusting screw.

[0010] As a further improvement of this utility model, the outer wall of the adjusting screw is connected to a nut via a thread.

[0011] The beneficial effects of this utility model are as follows: 1. This fall arrest device uses only a single locking block to work with the top head to support and prevent the falling attached lifting scaffold. The locking block is made of high-quality carbon steel plate through laser cutting and welding, which allows for more precise cutting of the carbon steel plate into the required size of the locking block, increasing the yield rate and reducing costs. At the same time, the locking block is compact in size, the manufacturing process is controllable, the quality is high, and the reliability of the fall arrest device during operation is improved.

[0012] 2. When the attached lifting scaffold body falls downwards, the top head on one side of the fixed seat will press against the fall arresting bar on one side of the falling attached lifting scaffold body. At the same time, the anti-fall block will also be squeezed by the falling fall arresting bar, and the end of the anti-fall block located at the bottom of the baffle will tilt upwards, so that the anti-fall block can press against the bottom of the falling fall arresting bar, and together with the top head, it will support the attached lifting scaffold body to prevent it from falling.

For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0019] Example 1: An attached lifting scaffold fall arresting device, such as Figure 1-4 As shown, the device includes a fixed base 1. A set of support plates 3 are fixed to one outer wall of the fixed base 1. A locking anti-fall block 4 is rotatably connected to one inner wall of the support plate 3 via a rotating rod. A baffle 16 is fixed to the opposite outer wall of the support plate 3. There is a gap between the baffle 16 and the top of the locking anti-fall block 4. The bottom outer wall of the locking anti-fall block 4 has a first inclined surface 12, a second inclined surface 13, a third inclined surface 15, and a fourth inclined surface 17. The length of the first inclined surface 12 is 59.03 mm, the length of the second inclined surface 13 is 29.37 mm, the length of the third inclined surface 15 is 38.64 mm, and the length of the fourth inclined surface 17 is 33.22 mm.

[0020] The length of the anti-fall block 4 is 133mm and the width is 35mm. The outer wall of the anti-fall block 4 has an insertion hole 14. The outer wall of the support plate 3 is fixed with a support frame 6, and a set of guide pulleys 5 are rotatably connected to the inner wall of the support frame 6. The outer wall of the support frame 6 has a guide hole 2, and the attached lifting scaffold body 11 is slidably connected to the inner wall of the guide hole 2. A bottom sleeve 10 is rotatably connected to one side of the outer wall of the support plate 3. An adjusting screw 8 is threadedly connected to the inner wall of the bottom sleeve 10. A top head 9 is fixed to one end of the adjusting screw 8. The adjusting screw 8 has a nut 7 connected to its outer wall by a thread.

[0021] The fixed seat 1 is fixed to one side of the building by bolts and other fasteners. When the attached lifting scaffold body 11 is raised as a whole according to the construction needs, the anti-fall stop bar on the outer wall of the attached lifting scaffold body 11 will also rise along with the attached lifting scaffold body 11. At this time, the top head 9 and the anti-fall block 4, which are rotatably connected on one side of the fixed seat 1, will bounce to one side under the action of the anti-fall stop bar on one side of the continuously rising attached lifting scaffold body 11, so as not to hinder the upward movement of the attached lifting scaffold body 11. When the attached lifting scaffold body 11 falls downwards, the top head 9 on one side of the fixed seat 1 will press against the anti-fall stop bar on one side of the falling attached lifting scaffold body 11. At the same time, the anti-fall block 4 will also be squeezed by the falling anti-fall stop bar, and one end of the anti-fall block 4 located at the bottom of the baffle 16 will be tilted upwards, so that the anti-fall block 4 can press against the bottom of the falling anti-fall stop bar, and together with the top head 9, it will support the attached lifting scaffold body 11 to prevent it from falling.

[0022] The anti-fall block 4 in this embodiment is made by laser cutting. It is made of high-quality carbon steel plate and is laser-cut and welded together. This process can cut the carbon steel plate into the required size of the anti-fall block 4 more accurately, increasing the yield and reducing the cost. At the same time, the anti-fall block 4 is small in size, the processing is controllable, the quality is high, and the reliability of the anti-fall device during operation is improved.

[0023] In this embodiment, three or more fixed seats 1 can be set on one side of the building's exterior wall so that when the attached lifting scaffold body 11 falls, multiple anti-fall devices can support the falling attached lifting scaffold body 11 together.

[0024] Working principle: When the attached lifting scaffold body 11 falls downwards, the top head 9 on one side of the fixed seat 1 will press against the anti-fall stop bar on one side of the falling attached lifting scaffold body 11. At the same time, the anti-fall block 4 will also be squeezed by the falling anti-fall stop bar, and one end of the anti-fall block 4 located at the bottom of the baffle 16 will be tilted upwards, so that the anti-fall block 4 can press against the bottom of the falling anti-fall stop bar, and together with the top head 9, it will support the attached lifting scaffold body 11 to prevent it from falling.

[0025] The anti-fall block 4 is made by laser cutting process. It is made of high-quality carbon steel plate and is laser-cut and welded together. This process can cut the carbon steel plate into the required size of the anti-fall block 4 more accurately, thus increasing the yield rate.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
