Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a fall prevention braking device for lifting scaffolding. Background Technology

[0002] The fall arrestor is the most important safety component of attached lifting scaffolding. When other protective measures (such as lifting equipment, connectors, etc.) fail and cause the scaffolding to fall, the fall arrestor can quickly lock the scaffolding through mechanical braking to prevent the overall collapse.

[0003] Existing fall arrestors for attached lifting scaffolding typically consist of fall arrest devices and braking systems. Fall arrest devices generally include fall arrest rods and fall arrest blocks, while braking systems have corresponding brake springs and brake plates. However, in existing systems, prolonged use of the wire ropes during operation can lead to wear and breakage. Inadequate lubrication and maintenance, as well as frequent overloading, can cause rapid corrosion of the wire ropes, impacting worker safety and work efficiency.

[0004] Therefore, we propose a fall arrestor for scaffolding to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fall prevention braking device for lifting scaffolds.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: Fixed protective devices are fixedly installed at both ends of the scaffold body; mounting plates are connected to the upper and lower ends of the fixed protective devices; holes are opened on the surface of the mounting plates, and mounting nails are installed inside the holes; a fixed plate is installed and connected inside the fixed protective devices; a lubrication pump is fixedly installed on the surface of the fixed plate, and multiple sets of atomizing nozzles are installed on the surface of the lubrication pump; an oil tank is connected to the upper end of the lubrication pump via an oil pipe; a safety plate is fixedly installed below the lubrication pump; and a check valve is installed on one side of the safety plate.

[0007] Preferably, the upper and lower ends of the fixed protective device are provided with grooves that are adapted to the edges of the scaffold body.

[0008] Preferably, the fixing plate itself is convex, and the surface of the lubrication pump has multiple sets of holes, which are adapted to the diameter of the atomizing nozzle.

[0009] Preferably, limit plates are fixedly installed at both ends of the scaffold body, and grooves adapted to the limit plates are opened on both sides of the lower end of the fixed protective device.

[0010] Preferably, a threaded fixing sleeve is installed on one side of the fixed protective device, and the diameter of the threaded fixing sleeve corresponds to the diameter of the groove opened on one side of the fixed protective device.

[0011] Preferably, the inner diameter of the threaded retaining sleeve is adapted to the fixed threaded rod, and the fixed threaded rod abuts against one side of the limiting plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device features an internal fixed plate with a fixed protective structure. A lubrication pump is mounted on the surface of the fixed plate, and multiple atomizing nozzles are connected to the surface of the lubrication pump. This allows for comprehensive spraying of lubricating oil during the rotation of the wire rope, preventing any areas from being left untouched. An oil tank is connected to the upper end of the lubrication pump via an oil pipe, and a mounting plate with a check valve is installed at the lower end of the pump. This prevents wear and breakage of the wire rope surface, ensuring regular lubrication and maintenance. It also prevents frequent overloading of the wire rope, avoids rapid corrosion, improves worker safety, and increases work efficiency.

[0013] 2. This device is installed and connected to the scaffold body by means of a fixed protective device. Mounting plates are installed at both ends of the fixed protective device and fixed with mounting nails to prevent it from falling off. At the same time, limit plates are installed on both sides of the lower end of the scaffold body, corresponding to the limit groove opened on one side of the fixed protective device. In addition, a threaded fixing sleeve is installed on one side of the fixed protective device, and the limit plate is fixed by a fixed threaded rod. This prevents the wire rope from being exposed on the outside and being damaged by human or environmental factors, and effectively protects the wire rope from oxidation and corrosion over a long period of time.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Reference Figure 1-4 The anti-fall braking device for the lifting scaffold includes: a scaffold body 1, with fixed protective devices 2 fixedly installed at both ends of the scaffold body 1 to protect the wire ropes, prevent large-area oxidation, and avoid corrosion. Mounting plates 3 are connected to the upper and lower ends of the fixed protective devices 2 for easy fixing and to prevent them from falling off during prolonged work. The mounting plates 3 have holes on their surface, and mounting nails 31 are installed inside the holes to increase stability. A fixing plate 21 is installed and connected inside the fixed protective device 2. This design facilitates the fixed installation of the spraying device, preventing slippage and detachment. The lubrication pump 22 is fixedly installed on the surface of the fixing plate 21 to effectively control the spraying effect of the oil pipe. The lubrication pump 22 is equipped with multiple sets of atomizing nozzles 23 to ensure comprehensive spraying and prevent any omissions. The upper end of the lubrication pump 22 is connected to the oil tank 25 via the oil pipe 24 to store lubricating oil for timely replenishment, preventing any impact on work efficiency. A safety plate 26 is fixedly installed below the lubrication pump 22, and a check valve 27 is installed on one side of the safety plate 26.

[0018] Furthermore, refer to Figure 1 It can be seen that the upper and lower ends of the fixed protective device 2 are provided with grooves that are compatible with the edge of the scaffold body 1, so as to facilitate mutual matching and installation, and prevent gaps that would affect the stability of the installation.

[0019] Furthermore, refer to Figure 3 It can be seen that the fixing plate 21 itself is convex to facilitate installation and fixation, and prevent shaking during operation, which could lead to detachment and affect the work process. In addition, the surface of the lubrication pump 22 has multiple sets of holes to facilitate comprehensive spraying, prevent any omissions, and ensure the safety of the staff and the maintenance of the machine. The holes are also compatible with the diameter of the atomizing nozzle 23.

[0020] Furthermore, refer to Figure 2 and Figure 4It can be seen that the two ends of the scaffold body 1 are fixedly installed with limit plates 32, which facilitates the limiting function during the fixing process and prevents the fixing protection device 2 from shaking. The lower ends of the fixing protection device 2 are provided with grooves that are compatible with the limit plates 32.

[0021] Furthermore, refer to Figure 1 and Figure 4 It can be seen that a threaded fixing sleeve 33 is installed on one side of the fixed protective device 2 to facilitate the installation of the threaded rod and prevent loosening that would affect the fixing effect. The diameter of the threaded fixing sleeve 33 corresponds to the diameter of the groove opened on one side of the fixed protective device 2 to prevent jamming. The inner diameter of the threaded fixing sleeve 33 is adapted to the fixed threaded rod 34, which facilitates the back-and-forth movement of the fixed threaded rod 34 inside the threaded fixing sleeve 33. The fixed threaded rod 34 abuts against one side of the limiting plate 32 to prevent the limiting plate 32 from sliding and affecting the stability of the fixed protective device 2.

[0022] Working Principle: In use, the limiting groove at the lower end of the fixed protective device 2 is inserted into the limiting plate 32. The fixed protective device 2 is then installed on both sides of the scaffold body 1. The mounting plate 3 corresponds to the upper and lower ends of the scaffold body 1. The fixed protective device 2 is fixed by inserting the mounting nail 31 into the mounting hole of the mounting plate 3. The threaded fixing sleeve 33 is used to insert the threaded rod 34 through the threaded hole to abut against the limiting plate 32. At this time, the lubrication pump 22, which is fixedly installed on the surface of the fixed plate 21, is started. The lubricating oil is introduced into the lubrication pump 22 through the oil pipe 24 connected to the oil outlet of the oil tank 25. The oil is then sprayed through multiple sets of atomizing nozzles 23. The scaffold body 1 is started, causing the wire rope to rotate, so that the atomizing nozzles 23 spray the wire rope comprehensively. At this time, the check valve 27 installed on the safety plate 26 prevents the lubricant from flowing back, ensuring the stability of the system.

[0023] The above is the complete working principle of this utility model.
