[0002] Aerial work platforms are special vehicles used for the installation, maintenance, and cleaning of high-altitude equipment. Compared with traditional methods such as scaffolding and ladders, they have advantages such as better performance, higher efficiency, and greater safety.

[0003] A search revealed that Chinese Patent Application No. 202322605118.4 discloses a hybrid boom aerial work platform, comprising a vehicle body, a box fixedly mounted on the outer wall of the vehicle body, a rotating platform rotatably connected to the top of the box, a rotating base fixedly mounted on the top of the rotating platform, a first drive cylinder rotatably connected to the outer wall of the rotating base, a first support arm rotatably connected to the outer wall of the rotating base, a second drive cylinder rotatably connected to the outer wall of the first support arm, a second support arm rotatably connected to the outer wall of the first support arm, a third drive cylinder mounted on the outer wall of the second support arm, a basket rotatably connected to the outer wall of the second support arm, a pressure switch fixedly mounted at the bottom of the inner cavity of the basket, a support assembly fixedly mounted at the bottom of the inner cavity of the basket, a load-bearing platform fixedly mounted on the top of the support assembly, a protective plate rotatably connected to the inner wall of the basket, and a fixing column fixedly mounted on the outer wall of the protective plate.

[0004] Regarding the aforementioned technologies, the inventors believe that the following technical defects exist and require improvement: Common aerial work platforms are typically rectangular hollow structures, allowing workers to stand inside. In particularly confined working conditions, the minimum width of the platform may exceed the narrow space, preventing workers from entering the confined area to perform tasks. In other words, workers cannot stand inside the platform to complete extreme operations. Utility Model Content

[0005] This application provides an aerial work platform bucket with an extension platform to improve the following technical problems: Common aerial work platforms are typically rectangular hollow structures, allowing workers to stand inside. In particularly confined working conditions, the minimum width of the platform may exceed the narrow space, preventing workers from entering the confined area to perform tasks. In other words, workers cannot stand inside the platform to complete extreme operations.

[0006] This application provides an aerial work platform with an extension platform, employing the following technical solution: A high-altitude work platform bucket includes a work platform body, an extension plate, two sets of tensioning assemblies, and two support rods. The bottom of the extension plate is hinged to the outer bottom of the work platform body, and the top of the extension plate is detachably fixed to the top of the work platform body. The two sets of tensioning assemblies are located on both sides of the extension plate, and the two support rods are located on both sides of the extension plate. The bottom of the support rod is hinged to the outer bottom of the work platform body, and the support rod and the work platform body are fixed by a locking device. One end of the tensioning assembly is fixed to the outer corner of the extension plate. When the extension plate is unfolded, the other end of the tensioning assembly is fixed to the top of the work platform body. When the extension plate is unfolded and the locking device is engaged, the top of the support rod is supported by the middle of the tensioning assembly, forming the extension platform.

[0007] In one feasible technical solution of this application, two hinge seats are fixed on the bottom outer side of the working bucket body, and the bottom sides of the extension plate are provided with horizontally arranged first rotating shafts, and the two first rotating shafts are respectively rotatably assembled on the inner side of the two hinge seats.

[0008] In one feasible technical solution of this application, the bottom of the support rod is provided with a horizontally arranged second rotating shaft, and the two second rotating shafts are respectively rotatably assembled on the outside of the two hinge seats.

[0009] In one feasible technical solution of this application, a first pin hole is provided in the middle of the support rod, a second pin hole is provided on the working bucket body, and the locking member includes a locking pin shaft, which passes through the second pin hole and the first pin hole in sequence.

[0010] In one feasible technical solution of this application, the locking member further includes a pull ring, which is fixed to the inner end of the locking pin.

[0011] In one feasible technical solution of this application, the tensioning assembly includes a tensioning rope and a limiting block. The limiting block is fixed to the inner end of the tensioning rope, and the outer end of the tensioning rope is fixed to the outer corner of the extension plate. A through hole is provided on the top of the working bucket body, and the tensioning rope slides through the through hole.

[0012] In one feasible technical solution of this application, the extended plate is a rectangular steel plate with multiple spaced-apart weight-reducing holes.

[0013] In one feasible technical solution of this application, the tensioning rope is a steel wire rope or a stainless steel ring chain, the limiting block is a disc structure, and the two ends of the tensioning rope are welded and fixed to the limiting block and the extension plate, respectively.

[0014] In one feasible technical solution of this application, a U-shaped locking block is slidably mounted on the beam at the top of the working bucket body. When the extension plate is in the retracted state, the top of the extension plate and the beam at the top of the working bucket body are locked together in the U-shaped locking block.

[0015] In one feasible technical solution of this application, a side panel is provided on each of the four sides of the lower half of the working bucket body, and three horizontally arranged side bars are provided on the upper half of the working bucket body. The three side bars are respectively located on three sides of the working bucket body that are not connected to the extension plate.

[0016] In summary, this application includes at least one of the following beneficial technical effects: A hinged extension plate and support rod are added to the bottom of the work platform. When the extension plate is unfolded and laid flat, the outer end of the extension plate can be tightened and fixed by the tensioning assembly. The support rod can be opened to support the middle of the tensioning assembly, thus forming guardrails on both sides of the extension plate. Moreover, the width of the entire extension platform is less than the minimum width of the work bucket body, making it convenient for workers to stand on the extension platform to perform extreme operations. It is suitable for narrow operating scenarios. In normal use scenarios, the extension plate and support rod can be stored and attached to the outer wall of the work bucket body. At the same time, the tensioning assembly can also be stored inside the work bucket body without affecting normal operation. It is very practical and convenient. Attached Figure Description

[0025] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0026] This application discloses an aerial work platform with an extension platform. (See also...) Figure 1-2The aerial work platform bucket includes a work platform body 1, an extension plate 2, two sets of tensioning components 3, and two support rods 4. The bottom of the extension plate 2 is hinged to the bottom outer side of the work platform body 1, and the top of the extension plate 2 is detachably fixed to the top of the work platform body 1. The two sets of tensioning components 3 are located on both sides of the extension plate 2, and the two support rods 4 are located on both sides of the extension plate 2. The bottom of the support rods 4 is hinged to the bottom outer side of the work platform body 1, and the support rods 4 and the work platform body 1 are fixed together by locking components 5. One end of the tensioning component 3 is fixed to the outer corner of the extension plate 2. When the extension plate 2 is unfolded, the other end of the tensioning component 3 is fixed to the top of the work platform body 1. When the extension plate 2 is unfolded and the locking components 5 are engaged, the top of the support rods 4 is supported in the middle of the tensioning component 3 and forms the extension platform.

[0027] In this embodiment, in order to improve the stability of the bottom hinge assembly of the extension plate 2 and the support rod 4, two hinge seats 6 are fixed on the outer side of the bottom of the working bucket body 1. The bottom sides of the extension plate 2 are provided with horizontally arranged first rotating shafts, and the two first rotating shafts are respectively rotatably assembled on the inner side of the two hinge seats 6. The bottom of the support rod 4 is provided with a horizontally arranged second rotating shaft, and the two second rotating shafts are respectively rotatably assembled on the outer side of the two hinge seats 6.

[0028] In this embodiment, a first pin hole is provided in the middle of the support rod 4, and a second pin hole is provided on the working bucket body 1. The locking component 5 includes a locking pin 51, which passes through the second pin hole and the first pin hole in sequence. The locking component 5 also includes a pull ring 52, which is fixed to the inner end of the locking pin 51. The locking component 5 designed above has a simple structure, is easy to insert and remove, and makes unlocking and fixing the support rod 4 very convenient and easy.

[0029] In this embodiment, the tensioning assembly 3 includes a tensioning rope 31 and a limiting block 32. The limiting block 32 is fixed to the inner end of the tensioning rope 31, and the outer end of the tensioning rope 31 is fixed to the outer corner of the extension plate 2. A through hole is provided on the top of the working bucket body 1, through which the tensioning rope 31 slides. The extension plate 2 is a rectangular steel plate with multiple spaced weight-reducing holes. The tensioning rope 31 is a steel wire rope or a stainless steel chain. The limiting block 32 is a disc structure. The two ends of the tensioning rope 31 are welded and fixed to the limiting block 32 and the extension plate 2, respectively. The tensioning assembly 3 designed above has a simple structure, is easy to store and unfold, and can provide a good fixing and tensioning effect for the extension plate 2 in its unfolded and flattened state.

[0030] The top of the support rod 4 is provided with a rope slot 41 that is adapted to the tension rope 31. When the support rod 4 is unfolded, the middle part of the tension rope 31 is locked in the rope slot 41, so that the support rod 4 can support the middle part of the tension rope 31.

[0031] To prevent the extended plate 2 from being unstable and wobbling when it is in the retracted state, a U-shaped locking block 7 is slidably installed on the beam at the top of the working bucket body 1. When the extended plate 2 is in the retracted state, the top of the extended plate 2 and the beam at the top of the working bucket body 1 are locked together in the U-shaped locking block 7.

[0032] In this embodiment, a side panel 11 is provided on each of the four sides of the lower half of the work bucket body 1, and three horizontally arranged side bars 12 are provided on the upper half of the work bucket body 1. The three side bars 12 are located on three sides of the work bucket body 1 that are not connected to the extension plate 2. The work bucket body 1 designed above provides good protection for the personnel inside. Moreover, when the extension plate 2 is unfolded, it is convenient for the personnel to step over the side panel 11 that does not have side bars 12 above and quickly stand on the extension platform to perform extreme operations in narrow spaces. At the same time, the extension plate 2 in the stored state can also fill the gap in the upper half of the corresponding side where there are no side bars 12, forming a good safety protection effect and reducing safety hazards.

[0033] The beneficial technical effects of the aerial work platform with extension platform in the embodiments of this application are roughly as follows: An extension plate 2 and a support rod 4, which are hinged together, are added to the bottom of the working platform. When the extension plate 2 is unfolded and laid flat, the outer end of the extension plate 2 can be tightened and fixed by the tensioning component 3. The support rod 4 can be opened to support the middle part of the tensioning component 3, thereby forming a guardrail on both sides of the extension plate 2 (for narrow operating environments, the guardrail formed by the tensioning component 3 and the support rod 4 has sufficient safety protection effect, and it is relatively safe for workers to stand on the extension plate 2). Moreover, the width of the entire extension platform is less than the minimum width of the working bucket body 1, which makes it convenient for workers to stand on the extension platform to complete extreme operations. It is suitable for narrow operating scenarios. In normal use scenarios, the extension plate 2 and the support rod 4 can be stored and attached to the outer wall of the working bucket body 1. At the same time, the tensioning component 3 can also be stored inside the working bucket body 1 without affecting normal operation. It is very practical and convenient.

[0034] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
