[0042] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0043] The following is combined Figures 1-6 This utility model describes a high-altitude work platform.

[0044] like Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, this utility model provides a high-altitude work platform 1, including: a work railing 11 and a connecting assembly 12. The work railing 11 has a working space 111 inside, used to carry workers and / or construction materials. A first mounting hole 112 is provided at the bottom of the work railing 11; a limiting member 113 is provided above the first mounting hole 112, and the limiting member 113 has a limiting groove 114 corresponding to the position of the first mounting hole 112. The connecting assembly 12 includes a base frame 121, a connector 122, and fasteners 123. The base frame 121 is configured to connect to the boom, and a second mounting hole is provided on the base frame 121 corresponding to the position of the first mounting hole 112. The connector 122 passes through the second mounting hole and the first mounting hole 112 in sequence and is threaded to the fastener 123, and cooperates with the fastener 123 to fix the base frame 121 and the work rail 11. The fastener 123 is located in the limiting groove 114, and the groove walls on opposite sides of the limiting groove 114 abut against the fastener 123 to prevent the fastener 123 from rotating.

[0045] In this embodiment, the work platform 11 has a working space 111 inside for workers to stand or place construction materials. For example, in order to reduce the weight of the work platform 11, the work platform 11 may include side rails and a base plate. The side rails and the base plate together form the working space 111. Workers can stand on the base plate to work, and construction materials can be placed on the base plate. The side rails are used to provide a support position for workers and to protect workers and construction materials, preventing workers or construction materials from falling from the side of the working space 111.

[0046] The base frame 121 of the connecting assembly 12 is used as a transitional connection structure between the work platform 11 and the boom. It is understood that the base frame 121 can be directly connected to the boom, or it can be connected to the boom through other structures. In this embodiment, the bottom of the base frame 121 and the work rail 11 are respectively provided with corresponding second mounting holes and first mounting holes 112, and a limiting member 113 is provided above the first mounting hole 112. When the work rail 11 is installed on the base frame 121, it is only necessary to place the fastener 123 in the limiting groove 114 of the limiting member 113. The connector 122 is inserted from the bottom of the base frame 121 through the second mounting hole and the first mounting hole 112 and into the threaded hole on the fastener 123. The fastener 123 will not rotate due to the limiting groove 114. Therefore, it is only necessary to screw the connector 122 so that the end of the connector 122 is gradually screwed into the threaded hole. The base frame 121 and the work rail 11 are fixed to each other through the cooperation of the connector 122 and the fastener 123.

[0047] When it is necessary to remove the work rail 11 from the base frame 121, since the fastener 123 will not rotate due to the limitation of the groove wall of the limiting groove 114, it is only necessary to twist the connector 122 in the opposite direction to disengage the end of the connector 122 from the threaded hole of the fastener 123. Then, pull the connector 122 out from the first mounting hole 112 and the second mounting hole, and the work rail 11 can be directly removed from the base frame 121.

[0048] The aerial work platform 1 of this utility model provides a working space 111 within a work railing 11 for workers to perform aerial work. The work railing 11 is connected to the boom of the aerial work equipment via a connecting component 12. Specifically, the bottom of the work platform 11 and the base frame 121 are provided with corresponding first mounting holes 112 and second mounting holes. The connector 122 passes through the first mounting holes 112 and second mounting holes and is threadedly connected to the fastener 123 in the work space 111 to fix the work platform 11 and the base frame 121. At the same time, the limiting member 113 in the work space 111 can limit the fastener 123 through the limiting groove 114 to prevent the fastener 123 from rotating. When disassembling or assembling the work platform 11, it is only necessary to screw the connector 122 to connect or separate the connector 122 and the fastener 123. This screwing process can be carried out on the outside of the work platform 11 (mainly at the bottom), making the working space more open and the operation more convenient. This effectively solves the problem in the prior art that when installing or repairing the work platform, it is necessary to work inside the work platform, the working space is small, and the operation is difficult.

[0049] It is understood that the first mounting hole 112 and the second mounting hole of this utility model can be threaded holes. When the threads are constructed in the first mounting hole 112 and the second mounting hole, the connector 122 can be threadedly connected to the inner wall of the first mounting hole 112 and the second mounting hole to further fix the work rail 11 and the base frame 121. However, after long-term use, the threaded hole may become blocked or the threads may corrode, making it difficult to disassemble and maintain the work rail 11.

[0050] Alternatively, the first mounting hole 112 and the second mounting hole of this utility model can be through holes without threads. Part of the structure on the connector 122 and the fastener 123 can respectively abut against the base frame 121 and the work rail 11 so as to clamp and fix the base frame 121 and the work rail 11. In this solution, the first mounting hole 112 and the second mounting hole are not easy to be blocked or corroded. Even if blockage or corrosion occurs, it is easier to remove the connector 122 from the first mounting hole 112 and the second mounting hole when disassembling the work rail 11, making disassembly and maintenance more convenient.

[0051] Specifically, the connector 122 can be a bolt; the fastener 123 can be a nut that is compatible with the bolt.

[0052] In some embodiments, such as Figure 1 , Figure 2 and Figure 3 As shown, the first mounting hole 112 is an oblong hole, and the extension direction of the limiting groove 114 is the same as the length direction of the oblong hole.

[0053] It is understandable that, due to factors such as assembly precision and welding precision, there may be some errors in the size and position of the first mounting hole 112 on the work rail 11 and the size and position of the second mounting hole on the base frame 121. These errors may cause the first mounting hole 112 and the second mounting hole to misalign during installation of the base frame 121 and the work rail 11. In this embodiment, by setting the first mounting hole 112 as an oblong hole, when the first mounting hole 112 and the second mounting hole are offset along the length direction of the oblong hole due to dimensional errors in some structures of the work rail 11 and the base frame 121, the second mounting hole can still communicate with the first mounting hole 112 if the degree of offset is not large, so that the connector 122 can be connected to the fastener 123 by passing through the second mounting hole and the first mounting hole 112. It is understandable that, since the first mounting hole 112 and the second mounting hole have shifted relative to the designed mounting position, the position of the fastener 123 will also shift relative to the designed mounting position. In this embodiment, by setting the extension direction of the limiting groove 114 to be the same as the length direction of the waist-shaped hole, the fastener 123 after the shift is still kept in the limiting groove 114, and the limiting groove 114 can still prevent the fastener 123 from rotating.

[0054] In some embodiments, such as Figure 2 and Figure 4 As shown, there are multiple first mounting holes 112, and the limiting groove 114, second mounting holes, connectors 122, and fasteners 123 are all arranged in a one-to-one correspondence with the first mounting holes 112. Among them, the length direction of a portion of the first mounting holes 112 is aligned with the length direction of the working space 111 (e.g., ...). Figure 4 The length direction of the other part of the first mounting hole 112 is the same as the width direction of the working space 111 (e.g., in the X direction). Figure 4 (In the Y direction) the same. The extension direction of the limiting groove 114 is the same as the length direction of the corresponding first mounting hole 112.

[0055] In this embodiment, by providing multiple first mounting holes 112, limiting members 113, second mounting holes, connecting members 122, and fasteners 123, multiple connection positions are provided between the base frame 121 and the work rail 11, thereby dispersing the force between the base frame 121 and the work rail 11 and making the connection between the base frame 121 and the work rail 11 more stable and reliable.

[0056] It is understood that the workspace 111 is typically a cuboid-shaped space or a similar cuboid-shaped space. The workspace 111 has a vertically extending height side and a horizontally extending long and wide side. The length direction of the workspace 111 is parallel to the long side, and the width direction is parallel to the wide side. In this embodiment, by setting the length direction of a portion of the oblong holes to extend along the length direction of the workspace 111, and setting the length direction of another portion of the oblong holes (i.e., the first mounting holes 112) to extend along the width direction of the workspace 111, when there are dimensional errors in some structures of the work railing 11 and the base frame 121, by slightly adjusting the position of the corresponding second mounting holes along the length direction of the oblong holes, each second mounting hole can be connected to the corresponding oblong hole, and the connector 122 can be allowed to pass through. This avoids the misalignment of the second mounting holes and the first mounting holes 112 due to dimensional errors in some structures of the work railing 11 and the base frame 121, which would affect the fixed connection of the work railing 11 and the base frame 121.

[0057] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the bottom of the workbench 11 has multiple first mounting points and multiple second mounting points. First mounting holes 112 are respectively provided at each first mounting point and each second mounting point; the length direction of the first mounting hole 112 at the first mounting point is the same as the width direction of the workspace 111; the length direction of the first mounting hole 112 at the second mounting point is the same as the length direction of the workspace 111. The multiple first mounting points are arranged at intervals along the length direction of the workspace 111, and the multiple second mounting points are also arranged at intervals along the length direction of the workspace 111. The lines connecting the first mounting points and the lines connecting the second mounting points are arranged at intervals along the width direction of the workspace 111.

[0058] In this embodiment, each first mounting point and each second mounting point are provided with at least one first mounting hole 112 for connection with the base frame 121. The first mounting point is used to provide an oblong hole extending along the width direction of the workspace 111; the second mounting point is used to provide an oblong hole extending along the length direction of the workspace 111.

[0059] Multiple first installation points are arranged at intervals along the length of the workspace 111 to form a row of installation points. Multiple second installation points are arranged at intervals along the length of the workspace 111 to form another row of installation points. The two rows of installation points are arranged at intervals along the workspace 111, which allows the installation points to be more evenly distributed at the bottom of the work rail 11, making the force between the base frame 121 and the work rail 11 more evenly distributed, thereby making the connection between the base frame 121 and the work rail 11 more stable and reliable.

[0060] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, the second mounting point is located on the side of the first mounting point away from the boom, and the length of the line connecting each of the first mounting points is less than the length of the line connecting each of the second mounting points.

[0061] In this embodiment, the first mounting point forms a row of mounting points that are relatively close to the boom, while the second mounting point forms a row of mounting points that are relatively far from the boom. The length of the line connecting each of the first mounting points is less than the length of the line connecting each of the second mounting points. This helps to make the stress on the base frame 121 more uniform and to make the base frame 121 more stable and reliable.

[0062] In some embodiments, such as Figure 1 , Figure 2 and Figure 4 As shown, multiple first mounting points are arranged symmetrically about the center line of the workspace 111 along its own width direction; multiple second mounting points are arranged symmetrically about the center line of the workspace 111 along its own width direction.

[0063] In this embodiment, by setting multiple first mounting points and multiple second mounting points to be arranged symmetrically about the center line of the workspace 111 along its own width direction, the stress points of the base frame 121 are also symmetrically distributed about the center line of the workspace 111 along its own width direction. This makes the stress on the base frame 121 on both sides of the center line of the workspace 111 along its own width direction more uniform and more stable and reliable.

[0064] In some embodiments, such as Figure 1 and Figure 5 As shown, the base frame 121 includes a first bracket 1211 and a second bracket 1212. The first bracket 1211 is disposed below the work rail 11, and a second mounting hole is disposed in the first bracket 1211; the second bracket 1212 is connected to the first bracket 1211 and disposed on one side of the work rail 11, and is fixedly connected to the work rail 11.

[0065] In this embodiment, the first bracket 1211 is provided with a second mounting hole. The first bracket 1211 is used to connect with the bottom structure of the work railing 11. The second bracket 1212 is vertically connected to the first bracket 1211. The second bracket 1212 is set on the side of the work railing 11 and is used to fix it to the side structure of the work railing 11 (e.g., the upright of the side guardrail). The second bracket 1212 and the first bracket 1211 can cooperate with each other to further enhance the stability of the connection between the base frame 121 and the work railing 11. The work railing 11 can be fixed in both the horizontal and vertical directions at the bottom. This can alleviate the imbalance problem of the work railing 11 when the center of gravity is unevenly distributed, and also prevent the work railing 11 from being unstable due to the failure of the bottom bolts or the main stress welds, thus further enhancing the stability of the connection between the base frame 121 and the work railing 11.

[0066] In one specific embodiment, such as Figures 1 to 5 As shown, the first support 1211 is an isosceles trapezoidal structure, with its upper and lower bases extending along the length of the workspace 111. Two first mounting points are provided at the bottom of the work platform 11. Figure 4 Midpoint A and point B) and two second installation points ( Figure 4 The two first mounting points (midpoints C and D) are located at the two apex corners of the first bracket 1211, and the two second mounting points are located at the two bottom corners of the first bracket 1211. Each mounting point is equipped with a mounting plate; the mounting plate of the first mounting point has two first mounting holes 112 spaced apart along the length of the working space 111, and the mounting plate of the second mounting point has two first mounting holes 112 spaced apart along the width of the working space 111. Limiting members 113 are welded to the upper side of the mounting plate, and each limiting member 113 has two limiting grooves 114. A grid plate for supporting workers and construction materials can be installed above the mounting plate.

[0067] In some embodiments, such as Figure 1 and Figure 5 As shown, the connecting assembly 12 also includes an adapter bracket 124 and a swing mechanism 125. The adapter bracket 124 is connected to the base frame 121; the swing mechanism 125 is swayably disposed on the adapter bracket 124 about a vertical axis, and the swing mechanism 125 is used to connect to the boom and to drive the adapter bracket 124 to swing relative to the boom.

[0068] In this embodiment, a transition bracket 124 and a swing mechanism 125 are provided between the boom and the base frame 121. The swing mechanism 125 is directly connected to the boom and can swing relative to the transition bracket 124. The swing mechanism 125 can drive the transition bracket 124 to swing relative to the boom, thereby causing the work platform 11 to swing within a certain angle range so as to adjust the position of the work platform 11 according to the operation requirements.

[0069] Specifically, the swing mechanism 125 can be a swing cylinder, with the fixed structure of the swing cylinder and the adapter bracket 124 fixedly connected, and the movable structure and the boom connected.

[0070] In some implementations, such as Figure 1 and Figure 5As shown, the aerial work platform 1 also includes a pressure sensor 13 and an alarm device 14. The pressure sensor 13 is mounted on an adapter bracket 124. The base frame 121 has a contact portion 1213 corresponding to the detection end of the pressure sensor 13, which presses against the upper side of the detection end of the pressure sensor 13. The adapter bracket 124 and the base frame 121 are movably connected. The alarm device 14 is communicatively connected to the pressure sensor 13 and is used to issue an alarm based on the pressure data fed back by the pressure sensor 13.

[0071] In this embodiment, a pressure sensor 13 is installed on the adapter bracket 124, and an abutment part 1213 is installed on the base frame 121. The abutment part 1213 presses down on the detection end of the pressure sensor 13 from above, and the base frame 121 can move relative to the adapter bracket 124 within a certain range, so that the base frame 121 can be pressed down under the action of the work railing 11, the load on the work railing 11, and the base frame 121 itself. Thus, pressure is generated on the detection end of the pressure sensor 13 through the abutment part 1213, and the pressure will change with the weight of the load on the work railing 11. The pressure sensor 13 can generate a corresponding electrical signal according to the detected pressure and transmit it to the alarm device 14. When the pressure data corresponding to the electrical signal exceeds the alarm threshold of the alarm device 14, the alarm device 14 will issue an audible or visual warning to remind the staff that the load in the current work railing 11 is overweight.

[0072] Optionally, the alarm device 14 can be installed on the work platform 11 or in other locations on the aerial work platform. Optionally, the alarm device 14 can be integrated into the control system of the aerial work platform. After the alarm device 14 detects that the load inside the work platform 11 is overloaded, the control system will restrict all functions of the aerial work platform except for lowering the aerial work platform 1.

[0073] Specifically, in some embodiments, such as Figure 5 As shown, the connecting assembly 12 also includes: a plurality of connecting arms 126; one end of the connecting arm 126 is rotatably connected to the adapter bracket 124, and the other end of the connecting arm 126 is rotatably connected to the base frame 121; the plurality of connecting arms 126 are arranged at intervals in the vertical direction.

[0074] In this embodiment, by providing a plurality of connecting arms 126 arranged vertically at intervals between the adapter bracket 124 and the base frame 121, with both ends of the connecting arms 126 rotatably connected to the adapter bracket 124 and the base frame 121 respectively, the adapter bracket 124 and the base frame 121 can move relative to each other. This allows the base frame 121 to press down under the action of gravity and generate pressure on the detection end of the pressure sensor 13 through the abutment part 1213, and to limit the range of motion of the base frame 121 relative to the adapter bracket 124, so as to avoid the base frame 121 and the work railing 11 tilting forward or backward excessively.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
