Description

Technical Field

[0001] This application relates to the field of aerial work equipment technology, and in particular to a foldable suspended basket and portable extension platform system. Background Technology

[0002] The use of suspended platforms (also known as suspended work platforms) has gradually become a trend. They are widely recognized in high-altitude operations such as exterior wall construction, curtain wall installation, insulation construction, and exterior wall maintenance and cleaning of high-rise and multi-story buildings. When steel structure construction is used for building roof projects, workers need to set up scaffolding platforms, planks, and other auxiliary equipment on site to facilitate workers to stand at high altitudes. Then, workers standing at high altitudes can carry out welding and painting operations between steel components in the air.

[0003] For example, Chinese Patent Application No. CN202223553506.4 discloses a mobile suspended basket device, including a basket body. The top two sides of the basket body are connected to symmetrically arranged suspension hooks. Multiple horizontal connecting rods are fixedly connected between the two suspension hooks in an equidistant linear array. The basket body includes two horizontal reinforcing rods and a U-shaped frame. The two horizontal reinforcing rods are arranged symmetrically from top to bottom and are U-shaped. One of the horizontal reinforcing rods has a U-shaped frame fixedly connected to the bottom end of the suspension hook at the top. The bottom of the U-shaped frame has a basket located inside the horizontal reinforcing rod. The top two sides of the U-shaped frame are fixedly connected to diagonal connecting rods fixedly connected to the suspension hooks. A platform is fixedly connected to the bottom side inside the basket. A pull hook is provided on one side of the U-shaped frame.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement:

[0005] Because commonly available construction suspended platforms occupy a large volume of space and cannot be folded, they are not very practical when used in special facades such as building corners and gaps, as they cannot reach certain work areas. Utility Model Content

[0039] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0040] This application discloses a foldable suspended basket. (See also...) Figure 1-2The foldable suspended basket includes an inner connecting frame 1. A detachable mounting assembly 2 for connecting a platform is located at the top of the connecting frame 1. A first side frame 3 is vertically hinged to one side of the connecting frame 1, and a second side frame 4 is vertically hinged to the other side of the connecting frame 1. An outer frame 5 is hinged between the outer sides of the first side frame 3 and the outer sides of the second side frame 4. A base plate 6 is horizontally hinged to the bottom of the outer frame 5. The two sides of the base plate 6 away from the hinge are detachably mounted to the inner sides of the first side frame 3 and the second side frame 4, respectively. The connecting frame 1, the first side frame 3, the second side frame 4, the outer frame 5, and the base plate 6 are all rectangular structures. In this embodiment, the hinges are all achieved by installing hinges.

[0041] To facilitate quick locking and unlocking of the base plate 6, a set of sliding pins 61 are provided on both sides of the lower inner surface of the base plate 6 away from the hinge. The inner side of the first side frame 3 is provided with a first insertion hole 31 that adapts to one set of sliding pins 61, and the inner side of the second side frame 4 is provided with a second insertion hole 41 that adapts to the other set of sliding pins 61.

[0042] To enhance the structural strength of the entire suspended platform, a first baffle 32 is provided at the bottom of the first side frame 3, a second baffle 42 is provided at the bottom of the second side frame 4, and a third baffle 51 is provided at the bottom of the outer frame 5. T-shaped or π-shaped support rods are provided inside the first side frame 3, the second side frame 4, and the outer frame 5.

[0043] In this embodiment, in order to facilitate the quick fixation of the suspended basket to the platform, the detachable installation component 2 includes a horizontally arranged installation frame 21. The two ends of the installation frame 21 are also provided with push-pull clamps 22 for locking the platform, and the two ends of the installation frame 21 are also provided with safety protection pins 23 for inserting into the platform.

[0044] The beneficial technical effects of the foldable suspended basket 200 of this application embodiment are roughly as follows:

[0045] When the base plate 6 is locked, the entire suspended platform is a fixed square structure, allowing workers to stand inside and perform various high-altitude operations. After unlocking the base plate 6 from the inside, it can be flipped up or down, thereby unlocking the connecting frame 1, the first side frame 3, the second side frame 4, and the outer frame 5 into a foldable parallelogram structure. This allows the second side frame 4 to approach and fit against the connecting frame 1, and the outer frame 5 to approach and fit against the first side frame 3. As a result, the entire suspended platform can be folded into a flat structure, making it convenient for use on special facades such as building corners and gaps, thus improving its practicality.
