Technical Field
[0001] This utility model relates to the field of aerial work platform technology, specifically to an anti-tilt safety system for aerial work platforms. Background Technology
[0002] Aerial work platforms are essential, mobile pieces of equipment used for various industries to perform high-altitude operations such as installation and maintenance. A typical aerial work platform consists of three parts: a base, a lifting mechanism, and a work platform. During operation, the lifting mechanism raises the work platform to the required working height. The work platform can be either a fixed platform (stationary) or an extension platform (extendable on one side to expand the working space).
[0003] However, existing aerial work platforms have the following disadvantages:
[0004] (1) Existing aerial work platforms have weak anti-tilt function. When in use, the platform tilts during high-altitude operations, and the device itself does not have anti-tilt measures, which increases the possibility of the device falling and increases the risk of workers' work.
[0005] (2) Existing aerial work platforms have weak rain protection at the top. When it rains suddenly, rainwater will drip from the top of the platform, making the bottom of the platform slippery and increasing the risk of slipping for workers. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: an anti-tilt safety system for aerial work platforms, comprising a platform body, a first fixing plate fixedly connected to the side of the platform body, a first fixing rod fixedly connected inside the first fixing plate, a support plate rotatably connected to the outer surface of the first fixing rod, a second fixing rod rotatably connected to the inner side wall of the support plate, a second fixing plate fixedly connected to the outer surface of the second fixing rod, a limit rod fixedly connected to the top of one side of the platform body, a limit ring slidably connected to the outer surface of the limit rod, a first connecting rod fixedly connected to the outer surface of the limit ring, an extendable baffle fixedly connected to one side of the surface of the first connecting rod, and a second connecting rod fixedly connected to one side of the extendable baffle.
[0008] Optionally, a limiting groove is provided on one side of the top of the platform body, and the second connecting rod is connected to the limiting groove. Through the connection between the second connecting rod and the platform body, the extendable cover can be supported and fixed on one side.
[0009] Optionally, a base plate is fixedly connected to the bottom of the platform body, a connecting plate is provided at the bottom of the base plate, and a rectangular plate is fixedly connected to the bottom of the connecting plate. The base plate supports and fixes the platform body, and the connecting plate and the rectangular plate work together to support the base plate, thereby improving the overall stability and strength of the device.
[0010] Optionally, the top of the connecting plate is provided with a threaded hole, and a fixing screw is threaded into the inside of the threaded hole. After the connecting plate and the base plate are attached, the fixing screw is rotated to make the fixing screw fit with the threaded hole, so that the base plate can be fixed on the top of the connecting plate.
[0011] Optionally, the support plate has a first circular slot inside, and the first fixing rod fits into the first circular slot. When the support plate is tilted, the first fixing rod limits the support plate, and the first circular slot also limits the support plate.
[0012] Optionally, a second circular slot is provided on one side of the support plate, and the second fixing rod is in contact with the second circular slot. When the support plate is tilted, the second fixing rod limits the support plate, and the second circular slot limits the support plate at the same time.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] 1. The anti-tilt safety system for the aerial work platform, through the arrangement of a first fixed plate, a first fixed rod, a support plate, a second fixed rod, and a second fixed plate, when in use, the device tilts, causing the first fixed plate and the first fixed rod to move. The movement of the first fixed rod causes the support plate to tilt. At the same time as the support plate tilts, the second fixed rod limits the support plate, and the second fixed plate supports and fixes the second fixed rod, thereby supporting the platform and achieving the effect of improving the stability of the platform.
[0015] 2. This aerial work platform anti-tilt safety system, through the setting of a limit rod, a limit ring, a first connecting rod, an extendable barrier, and a second connecting rod, allows the limit rod to limit the limit ring during use. The worker can manually pull the limit ring, which moves the first connecting rod, causing the extendable barrier to extend. At the same time, the second connecting rod fixes one side of the extendable barrier, thereby sealing the top of the platform. This improves the practicality of the device and prevents rainwater from dripping from the top of the platform during sudden rain, which could make the bottom of the platform slippery and increase the possibility of workers slipping.
