[0061] The exemplary embodiments of this disclosure are described below with reference to the accompanying drawings, including various details of the embodiments to aid understanding, and should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of this disclosure. Similarly, for clarity and brevity, descriptions of well-known functions and structures are omitted in the following description.

[0062] A work platform typically includes a ladder and a work platform. The work platform is at a certain height from the ground, such as 1.5 to 2 meters, but this height is not limited to this. One end of the ladder can be installed on the ground and the other end can be installed on the work platform, allowing users to climb up and down the work platform. The work platform provides users with a working space where they can complete their work.

[0063] In related technologies, due to the height of the work platform, its center of gravity is raised. Also, due to uneven ground, the work platform may tilt or even fall over when users walk or work on it. This not only seriously affects the safety of users, but also endangers the safety of personnel and facilities around the work platform.

[0064] To address at least one of the aforementioned technical problems, this disclosure provides a work frame, including a support body, a work platform, and a connecting structure. The work platform is mounted on the support body, and the connecting structure is disposed on the support body and / or the work platform, the connecting structure being used to connect the work frame to other objects. The solution provided by this disclosure effectively solves at least one of the aforementioned technical problems.

[0065] like Figure 1 As shown, this embodiment of the disclosure provides a work frame, including a support body 10, a work platform 20, and a connecting structure 30. The work platform 20 is disposed on the support body 10, and the connecting structure 30 is disposed on the support body 10 and / or the work platform 20. The connecting structure 30 is used to connect the work frame to other objects.

[0066] According to the embodiments of this disclosure, it should be noted that:

[0067] The work platform 20 is mainly used for users to work on. The work platform 20 may include a plate-like or mesh-like structure. For example, the work platform 20 may be a flat plate structure or a wire mesh structure with supporting capacity. The shape of the work platform 20 may be designed according to the specific use scenario. For example, in some places with limited space, the work platform 20 may be set as a rectangle.

[0068] In some embodiments, the support body 10 is disposed below the work platform 20 to support the work platform 20 and enable the work platform 20 to maintain a certain distance from the ground. The support body 10 can be a frame structure made of rod-shaped bodies to save manufacturing materials and reduce the overall weight of the work frame, or the support body 10 can be a frame structure made of plate-shaped bodies.

[0069] The connecting structure 30 can be positioned in different locations. It can be positioned on the support body 10, meaning that the connecting structure 30 is connected to the support body 10. Alternatively, it can be positioned on the working platform 20, meaning that the connecting structure 30 is connected to the working platform 20. It can also be positioned on both the support body 10 and the working platform 20 simultaneously, meaning that the connecting structure 30 is connected to both the support body 10 and the working platform 20. In addition, the connecting structure 30 can also be connected to other objects.

[0070] The other objects mentioned here are those that provide stable support for the work scaffold, preventing it from tilting or falling over. They are inherently difficult to move. For example, in different usage scenarios, other objects can be the walls of buildings within a construction site, or equipment within a manufacturing plant. In the following embodiments, other objects are described using equipment from a manufacturing plant as an example.

[0071] When the work rack is needed, move the work rack close to the equipment, and then connect the connecting structure 30 to the equipment to form a reliable connection between the work rack and the equipment, so that the work rack will not tilt or tip over.

[0072] In some embodiments, the number of connection structures 30 can be multiple. For example, the number of connection structures 30 can be two. Taking the connection structure 30 connected to the work platform 20 as an example, the two connection structures 30 can be arranged on both sides of the work platform 20 in a symmetrical or asymmetrical manner. Of course, the number of connection structures 30 is not limited to this, and can also be three or four, etc. This disclosure does not make a specific limitation on the number.

[0073] According to the embodiments of this disclosure, the support 10 and / or the work platform 20 are connected to the equipment through the connecting structure 30. On the one hand, the work frame can be supported on the ground by itself, and on the other hand, the work frame can be attached to the equipment through the connecting structure 30, so that the work frame and the equipment can form a reliable connection, thereby preventing the work frame from tilting or falling over. This is beneficial to ensuring the safety of personnel on the work frame, and at the same time, it can also avoid the problem of injury to surrounding facilities or personnel caused by the work frame falling over.

[0074] In one embodiment, such as Figure 1 and Figure 2 As shown, the connection structure 30 includes a first connector 31 and a second connector 32. The first connector 31 extends along a first direction x and is connected to the support body 10 and / or the working platform 20. The first connector 31 is provided with a first connecting part for connecting to the equipment. The second connector 32 extends along a second direction y and is connected to the first connector 31. The second connector 32 is provided with a second connecting part for connecting to the equipment. The first direction x and the second direction y are not parallel.

[0075] According to the embodiments of this disclosure, it should be noted that:

[0076] The first connector 31 and the second connector 32 can be rod-shaped, plate-shaped, or other structures, as long as they can achieve connection with the support 10 and / or the work platform 20 and the equipment. The first connector 31 can be connected to the support 10, the work platform 20, or both. By providing a first connection part for connecting to the equipment on the first connector 31 and a second connection part for connecting to the equipment on the second connector 32, since the extension direction of the first connector 31 and the extension direction of the second connector 32 are not parallel, the connection structure 30 can be connected to the equipment from two different directions. Even if there is loose connection in one direction, the stability of the connection can still be ensured due to the connection effect in the other direction. That is, connecting from two directions can provide better stability.

[0077] The first connecting part and the second connecting part can be any suitable structure. For example, the first connecting part and the second connecting part can be at least one of the threaded structures, that is, the first connecting part and the second connecting part can be threaded holes or through holes (non-threaded holes, which are connected by bolts passing through the through holes and engaging with the threads of the nuts) located on the first connecting part 31 and the second connecting part 32. When it is a threaded hole, it can be connected to the threaded hole by bolts on the equipment. Furthermore, the first connecting part and the second connecting part can also be at least one of the snap-fit ​​structures, such as the first connecting part and the second connecting part can be one of the tenon and mortise structures. In addition, the first connecting part and the second connecting part can also be one of the positioning post or the positioning hole. For example, a prism-shaped positioning post can be provided on the first connecting part 31 and a positioning hole that engages with the prism-shaped positioning post can be provided on the second connecting part 32 to realize the connection between the first connecting part 31 and the second connecting part 32.

[0078] The number of first connecting parts on the first connecting member 31 can be one or two or more, and the number of second connecting parts on the second connecting member 32 can be one or two or more. The embodiments disclosed herein do not specifically limit this.

[0079] Here, the first direction x can be perpendicular to the vertical plane of the length direction of the working platform 20, while the second direction y can be parallel to the horizontal plane of the length direction of the working platform 20. The first direction x and the second direction y can be in the same plane, or they can be in different planes. The specific direction can be determined according to the specific shape of the equipment. For example, when the equipment is roughly a cuboid or a cylinder, the first connecting part and the second connecting part can be located on the top surface of the equipment. In this case, the first connecting part and the second connecting part are coplanar.

[0080] In one embodiment, such as Figure 1 and Figure 2As shown, the connection structure 30 also includes a third connector 33 extending along the third direction z. The third connector 33 is connected to the support body 10 and / or the working platform 20. One end of the first connector 31 is connected to the second connector 32, and the other end of the first connector 31 is connected to the third connector 33. The first direction x is perpendicular to the second direction y, the first direction x is perpendicular to the third direction z, and the second direction y is perpendicular to the third direction z. When the first direction x and the second direction y are on the same horizontal plane, the first direction x and the third direction z are on the same vertical plane.

[0081] According to the embodiments of this disclosure, it should be noted that:

[0082] The third connector 33 can be a rod-shaped body, a plate-shaped body, or other structures. The third connector 33 serves to connect the first connector 31 and the second connector 32 to the support body 10 and / or the work platform 20. The third connector 33 can also be connected to the support body 10 and / or the work platform 20 through threaded structures, tenon and mortise structures, positioning pins, or positioning holes as described in the above embodiments.

[0083] Because a third connector 33 is added and is perpendicular to the first connector 31, the third connector 33 can increase the contact area with the support 10 and / or the working platform 20 in the vertical direction, thereby increasing the connection stability between the connection structure 30 and the support 10 and / or the working platform 20.

[0084] In one embodiment, such as Figure 2 As shown, the first connecting part is the first connecting hole 311, the second connecting part is the second connecting hole 321, and the third connecting member 33 is provided with a third connecting hole (not shown in the figure). The third connecting hole is used to connect with the support body 10 and / or the working platform 20.

[0085] As described in the above embodiments, the first connecting hole 311, the second connecting hole 321, and the third connecting hole in the embodiments of this disclosure can be threaded holes or through holes. Depending on the different forms of the connecting holes, bolts or bolts and nuts can be selected for connection.

[0086] By employing the first connecting hole 311, the second connecting hole 321, and the third connecting hole, the connecting structure 30 can be easily disassembled and assembled with the equipment and the support body 10 and / or the work platform 20, respectively, making it convenient for the work frame to be used in different positions. For example, after repairing a piece of equipment in the manufacturing plant, the first connecting piece 31 and the second connecting piece 32 can be disassembled from the repaired equipment, and the work frame can be moved to the next piece of equipment to be repaired, and the first connecting piece 31 and the second connecting piece 32 can be installed on the equipment to be repaired.

[0087] In one embodiment, at least one of the first connecting hole 311, the second connecting hole 321, and the third connecting hole is an elongated hole.

[0088] Considering factors such as the unevenness of the ground surface (e.g., uneven ground), manufacturing and assembly errors of the work frame, and the difficulty in precisely controlling the relative position of the work frame and the equipment, at least one of the first connecting hole 311, the second connecting hole 321, and the third connecting hole is designed as an elongated hole. For example, when the ground is uneven, the depressions in the ground will reduce the relative height of the work frame. When the third connecting hole is a through hole and a bolt and nut are used to engage the third connecting hole, the height of the connecting structure 30 relative to the ground can be changed by adjusting the position of the bolt and nut relative to the length of the third connecting hole. This ensures that the first connecting piece 31 and the second connecting piece 32 are located on the top surface of the equipment, allowing the first connecting piece 31 and the second connecting piece 32 to be accurately connected to the equipment. For example, the top surfaces of multiple devices are often not at the same height. The elongated third connecting hole allows for easy adjustment of the height of the connecting structure 30. During use, it can be ensured that the positions of the first connecting piece 31 and the second connecting piece 32 are both higher than the top surface of the device. Then, the height of the connecting structure 30 can be adjusted according to different devices. This allows the work frame to adapt to devices of different heights and also avoids collisions between the connecting structure 30 and devices with higher top surfaces. Furthermore, some devices have threaded holes corresponding to the first connecting hole 311 and the second connecting hole 321. Due to manufacturing precision limitations, the threaded holes in the first direction x and the second direction y may be difficult to align with the first connecting hole 311 and the second connecting hole 321. The elongated first connecting hole 311 and the second connecting hole 321 can compensate for the manufacturing precision limitations of the threaded holes on the device, ensuring alignment between the first connecting hole 311, the second connecting hole 321, and the threaded holes on the device.

[0089] In other embodiments, the third connecting hole may also be a non-elongated hole, while the holes on the support 10 and / or the working platform 20 that are used to mate with the third connecting hole are set as elongated holes, which can also achieve height adjustment of the connecting structure.

[0090] In one embodiment, such as Figure 1 As shown, the work platform 20 includes a platform 21 and a fence 22. The platform 21 is at least for users to work on, and the fence 22 at least partially surrounds the platform 21. The fence 22 has an opening 68 for users to enter and exit.

[0091] According to the embodiments of this disclosure, it should be noted that:

[0092] Platform 21 is mainly used for users to work on. As in the above embodiment, platform 21 includes a plate-like body or a mesh-like body structure. For example, platform 21 can be a flat plate structure or a wire mesh structure with supporting capacity. The shape of platform 21 can be designed according to the specific use scenario. For example, in some places with limited space, platform 21 can be set as a rectangle. In this embodiment, platform 21 is a rectangular flat plate structure.

[0093] Platform 21 is mounted on support body 10. In other words, platform 21 is supported by support body 10, so that it can maintain a certain distance from the ground, making it convenient for users to stand on it and work at height. Platform 21 and support body 10 can be connected in any suitable way. For example, platform 21 and support body 10 can be connected together by welding, screwing, etc.

[0094] The fence 22 at least partially surrounds the platform 21, meaning that the fence 22 can surround multiple sides of the platform 21 from a position higher than the platform 21. These multiple sides also adapt to the shape of the platform 21. When the platform 21 is circular, the fence 22 surrounds most of the area of ​​the platform 21 from the outer circumference of the platform 21. When the platform 21 is rectangular, the fence 22 surrounds the platform 21 from three sides, and the remaining side is an opening 68, so that users can enter and exit the fence 22 through the opening 68. By using the fence 22 to surround the platform 21, the risk of people or objects falling from the side of the platform 21 can be prevented.

[0095] The users of the work platform are generally adults, whose height is usually between 1.5m and 1.9m. Therefore, in order to facilitate the user's arms to reach over the fence 22 to work, while also preventing people from falling, the height of the fence 22 relative to the work platform 20 can be selected to be between 1000mm and 1200mm.

[0096] The number of fences 22 can be one or more. For example, the number of fences 22 can be one, and from a top view, the fence 22 has a U-shaped integrated structure; the number of fences 22 can also be three, and the three fences 22 can be spliced ​​together to form a U-shaped structure. In this case, the three fences 22 are a separate structure.

[0097] In the embodiments of this disclosure, the fence 22 can be connected to the platform 21 by hinge, and the fence 22 is a three-part structure. Specifically, the three fences 22 can be hinged to the platform 21 by hinges. When the three fences 22 are flipped above the platform 21 and perpendicular to the platform 21, the fences 22 can be detachably fixed to each other by screws or snaps, thereby ensuring that the adjacent fences 22 can be tightly connected. It can be understood that at this time, the height of the work frame is equal to the height of the highest point of the fence 22 from the ground. When the three fences 22 are flipped below the platform 21 and perpendicular to the platform 21, it can be understood that at this time, the height of the entire work frame is the height of the platform 21 from the ground. Thus, by flipping the fence 22, the height of the work frame can be changed to reduce the space occupied by the work frame and facilitate the transportation of the work frame. In addition, in some usage scenarios where the platform 21 is required but the fence 22 is not required (for example, when the space of the construction site is small and three sides are close to the wall), flipping the fence 22 to the bottom of the platform 21 can also make the operation more convenient.

[0098] In one embodiment, such as Figure 1 As shown, the fence 22 includes a first railing 221, a second railing 222, a first vertical bar 223, and a second vertical bar 224. The first railing 221 is located above the platform 21 and at least partially surrounds the platform 21. The second railing 222 is located on the side of the first railing 221 away from the platform 21 and at least partially surrounds the platform 21. The first vertical bar 223 is disposed on the platform 21 and connects the first railing 221 and the second railing 222 on the first side of the platform 21. The second vertical bar 224 is disposed on the platform 21 and connects the first railing 221 and the second railing 222 on the second side of the platform 21.

[0099] According to the embodiments of this disclosure, it should be noted that:

[0100] The first railing 221 and the second railing 222 are horizontal bars, that is, they are located on a plane parallel to the platform 21. As in the above embodiment, the shape of the first railing 221 can be determined according to the shape of the platform 21. Furthermore, the first railing 221 can be a one-piece structure or a split structure. Taking a rectangular platform 21 as an example, the shape of the first railing 221, viewed from above, is a U-shaped structure. In this case, the number of first railings 221 can be one, two, or three. It can be understood that when the number of first railings 221 is one... The first railing 221 is a one-piece structure. When there are two or three first railings 221, the first railing 221 is a split structure. When there are two first railings 221, one of the first railings 221 is straight and the other is L-shaped, so that the two first railings 221 form a U-shape. When the platform 21 is circular, the shape of the first railing 221 can be C-shaped. In this case, the first railing 221 can also be a one-piece structure or a split structure composed of multiple segments spliced ​​together to form a C-shape.

[0101] The structure of the second railing 222 can be the same as that of the first railing 221, and its structure will not be described in detail here.

[0102] The distance between the first railing 221 and the second railing 222 can be approximately equal to the distance between the first railing 221 and the platform 21. This ensures that the gap between the first railing 221 and the second railing 222 is approximately the same size as the gap between the first railing 221 and the platform 21, thereby ensuring that the different gaps at the top and bottom can effectively prevent people from falling.

[0103] The first vertical bar 223 is arranged perpendicular to the platform 21. The first vertical bar 223 can be connected to the first railing 221 and the second railing 222 by welding, screwing, or snap-fitting. The function of the first vertical bar 223 is to form a grid-like fence 22 with the first railing 221 and the second railing 222, which reduces the amount of material used in the work frame and lowers its weight while ensuring that personnel are less likely to fall. The first vertical bar 223 being located on the platform 21 means that the first vertical bar 223 is connected to the platform 21. In the above embodiment, the first vertical bar 223 can be hinged to the platform 21. Of course, in other embodiments, the first railing 221 can be hinged to the platform 21, while the first vertical bar 223 is not connected to the platform 21.

[0104] The structure of the second vertical bar 224 can be the same as that of the first railing 221. The difference is that the positions of the first vertical bar 223 and the second vertical bar 224 are different. Their structures will not be described in detail here.

[0105] The number of first vertical bars 223 and second vertical bars 224 can be multiple. That is, more than two first vertical bars 223 can be set on the first side of the platform 21, and more than two second vertical bars 224 can be set on the second side of the platform 21. Multiple first vertical bars 223 and second vertical bars 224 can further reduce the size of the grid formed by the railings and vertical bars, thereby ensuring the safety of personnel.

[0106] like Figure 1 As shown, the platform 21 is a rectangle. Taking the first vertical bar 223 as an example, the platform 21 has two long sides along its length. The two vertical surfaces containing the long sides are the first side and the second side, which are opposite to each other.

[0107] In the above embodiments, the third connector 33 can be disposed on the first vertical rod 223 or the second vertical rod 224, and the third connector 33 is parallel to the first vertical rod 223 or the second vertical rod 224.

[0108] The first railing 221, the second railing 222, the first vertical bar 223, and the second vertical bar 224 can adopt a tubular structure, such as a square or rectangular tube or a round tube. This helps to reduce the weight of the work frame and also makes it convenient to connect them by welding.

[0109] The distance between the first railing 221 and the second railing 222 can be 450-550mm. This distance effectively prevents people from falling, saves material and reduces weight of the fence 22, and also allows users to work through the gap between the first railing 221 and the second railing 222 (for example, to maintain the upper part of equipment).

[0110] In one embodiment, such as Figure 1 and Figure 3 As shown, the second railing 222 includes a first member 2221, a second member 2222, and a third member 2223. The first member 2221 is located on the first side of the platform 21. The second member 2222 is parallel to the first member 2221 and located on the second side of the platform 21. The third member 2223 is detachably disposed between the first member 2221 and the second member 2222. The third member 2223 is opposite to the opening 68.

[0111] As in the above embodiment, the second railing 222 is a split structure. By detachably setting the third rod 2223 between the first rod 2221 and the second rod 2222, when there is a protruding part of the equipment, the third rod 2223 can be removed so that the protruding part of the equipment can extend into the interior of the fence 22, avoiding interference between the second railing 222 and the equipment. This also reduces the distance between the equipment and the work frame, facilitating close-range operation.

[0112] The third member 2223 can be detachably connected to the first member 2221 and the second member 2222 by means of screwing, snap-fitting or other methods.

[0113] In one embodiment, such as Figure 1 As shown, the work platform 20 also includes a tool box 23, which is detachably mounted on at least one of the first member 2221, the second member 2222, and the third member 2223.

[0114] According to the embodiments of this disclosure, it should be noted that:

[0115] As the name suggests, toolbox 23 is mainly used to store tools and other items. When a user needs a large variety of tools, some tools can be held in hand while others are placed in toolbox 23, making it convenient for the user to work. The size of toolbox 23 or the number of toolboxes 23 can be used to meet the specific needs of the tools. When there are many tools, a large-capacity toolbox 23 or multiple small-capacity toolboxes 23 can be used.

[0116] The tool box 23 is detachably mounted on at least one of the first rod 2221, the second rod 2222, and the third rod 2223. This means that the tool box 23 can be selectively mounted on one of the first rod 2221, the second rod 2222, and the third rod 2223 as needed. When the user is working on different sides of the platform 21, the tool box 23 is placed on the rod that the user is facing, making it convenient for the user to take out and put away tools. In addition, when there are many tool boxes 23, one or more tool boxes 23 can be selectively placed on two rods or on three rods.

[0117] For example, the toolbox 23 can be suspended from the first railing 221 or the second railing 222 by a hook or an opening-down groove, so as to facilitate the retrieval and placement of the toolbox 23.

[0118] In one embodiment, such as Figure 1 As shown, the working platform 20 also includes a baffle 24, which at least partially surrounds the platform 21. The baffle 24 is connected to the first vertical rod 223 and the second vertical rod 224, and the distance between the baffle 24 and the platform 21 is 3 to 7 mm.

[0119] According to the embodiments of this disclosure, it should be noted that:

[0120] The baffle 24 is a plate-shaped structure. The arrangement path of the baffle 24 can be parallel to the arrangement path of the first railing 221 or the second railing 222. The baffle 24 is closer to the platform 21 than the first railing 221 or the second railing 222.

[0121] The baffle 24 is connected to the first vertical rod 223 and the second vertical rod 224 by any suitable structure. For example, the baffle 24 can be connected to the first vertical rod 223 and the second vertical rod 224 by welding, or by binding the baffle 24 to the first vertical rod 223 and the second vertical rod 224 with ropes, thin wires, etc.

[0122] In other embodiments, the baffle 24 may also have other connection positions, and the fence 22 may include a third railing (not shown in the figure, i.e., an additional railing added on the basis of the first railing 221 and the second railing 222). The third railing is parallel to the arrangement path of the first railing 221 or the second railing 222, and at least partially surrounds the periphery of the platform 21. The third railing is set close to the platform 21, and the baffle 24 may be connected to the third railing.

[0123] The distance between the baffle 24 and the platform 21 is 3 to 7 mm, which means the distance can be 3 mm, 4 mm, 5 mm, 6 mm or 7 mm.

[0124] In the above embodiments, such as the first railing 221 and the second railing 222, the baffle 24 can also adopt an integrated structure or a split structure, which will not be elaborated here.

[0125] In the embodiments of this disclosure, by setting the distance between the baffle 24 and the platform 21 to a range of 3 to 7 mm, when the work frame is placed in the open air, even if it rains, no liquid will accumulate on the platform 21. At the same time, this distance range can also prevent items (such as parts and tools) on the platform 21 from falling off.

[0126] In one embodiment, such as Figure 1 As shown, the work platform 20 also includes a spring-loaded door 25, which is connected to the first vertical bar 223 or the second vertical bar 224. The spring-loaded door 25 has an open position and a closed position. Under the action of the spring-loaded force, the spring-loaded door 25 has a tendency to move from the open position to the closed position. In the closed position, the spring-loaded door 25 prevents the user from passing through the opening 68.

[0127] According to the embodiments of this disclosure, it should be noted that:

[0128] The spring-loaded door 25 refers to a door that always tends to move back to its initial position. That is, when there is no external force, the spring-loaded door 25 will always remain in its initial position. Under the action of an external force, the spring-loaded door 25 can be moved away from its initial position. When the external force is removed, the spring-loaded door 25 will automatically return to its initial position. The spring-loaded door 25 can be connected to the first vertical bar 223 or the second vertical bar 224 through a torsion spring or a spring-loaded hinge. Under the action of an external force, the spring-loaded door 25 can apply a compressive force to the torsion spring or the spring-loaded hinge, thereby moving away from its initial position. When the external force is removed, the spring-loaded door 25 can return to its initial position by relying on the restoring force of the torsion spring or the spring-loaded hinge.

[0129] like Figure 1 As shown, at this time, the spring-loaded door 25 is in the open position. After the spring-loaded door 25 rotates 90 degrees, it is in the closed position (i.e., the initial position mentioned above). Alternatively, when the spring-loaded door 25 moves to be parallel to the first rod 2221 or the second rod 2222, it is in the open position. When the spring-loaded door 25 moves to be perpendicular to the first rod 2221 or the second rod 2222, it is in the closed position.

[0130] When a user stands inside the fence 22 and is about to open the spring-loaded door 25, sufficient space must be provided to avoid interference between the user's body and the spring-loaded door 25 during the opening process. The length of this space (the distance between the third rod 2223 and the spring-loaded door 25 when it is in the open position) should be no less than 450mm. Its maximum length can be set as needed, such as 1000mm, 2000mm, 3000mm, etc.

[0131] In the embodiments of this disclosure, the normally closed function of the spring-loaded door 25 can make the spring-loaded door 25 and the fence 22 form a four-sided closed structure. That is, the spring-loaded door 25 blocks part of the opening 68. When the user is working on the platform 21, even if he slips, he will not fall through the opening 68, thereby ensuring the safety of the user.

[0132] In other embodiments, the fence 22 may also include a limiting part (not shown in the figure), which is used to prevent the spring-loaded door 25 at the closed position from moving away from the open position. That is, the limiting part can prevent the spring-loaded door 25 from opening in the opposite direction under the action of external force when the spring-loaded hinge or torsion spring fails, thereby ensuring the safety of personnel on the platform 21. The limiting part may be a limiting post or limiting protrusion or other structure provided on the first railing 221, the second railing 222, the first vertical bar 223 or the second vertical bar 224. One end of the limiting part is provided on the first railing 221, the second railing 222, the first vertical bar 223 or the second vertical bar 224, and the other end of the limiting part extends toward the spring-loaded hinge or torsion spring.

[0133] In one embodiment, such as Figure 4 As shown, the fence 22 also includes a locking element 26, which is connected to the first railing 221 or the second railing 222 to lock the spring-loaded door 25 in the open position.

[0134] In some situations, it is necessary to keep the spring-loaded door 25 in the open position at all times, such as when parts or tools need to be continuously moved onto the platform 21. In this case, the spring-loaded door can be locked in the open position by the locking element 26, which can facilitate the user to move parts or tools and avoid frequently opening or closing the spring-loaded door 25.

[0135] The locking element 26 can be any suitable structure. For example, the locking element 26 can be a magnet installed on the first railing 221 or the second railing 222. By attracting the spring door 25 with the magnet, the spring door 25 can be kept in the open position. It should be understood that the attraction force of the magnet should be greater than the springing force of the spring door 25. The locking element 26 can also be a pin. Correspondingly, the spring door 25 is provided with a hole that cooperates with the pin. By inserting the pin into the hole, the spring door 25 can also be locked in the open position.

[0136] In one embodiment, such as Figure 4 As shown, the support body 10 includes multiple sets of support columns, which define a first avoidance space 40 and a second avoidance space 50. The first avoidance space 40 is used to avoid a first interference object, and the second avoidance space 50 is used to avoid a second interference object. The position of the first interference object is higher than the position of the second interference object.

[0137] According to the embodiments of this disclosure, it should be noted that:

[0138] The support columns are used to form the support body 10, thereby providing support for the platform 21. In other words, the platform 21 is set on multiple sets of support columns.

[0139] Many pieces of equipment in manufacturing plants are not perfectly regular in shape, often having protruding parts at the top and bottom. To ensure the work platform is as close as possible to the equipment and not interfered with by these protruding parts, multiple sets of support columns can be arranged to create a first clearance space 40 and a second clearance space 50. This prevents interference between the protruding parts at the bottom of the equipment and the work platform. The first clearance space 40 and the second clearance space 50, with their different heights, allow for the avoidance of interfering objects at different heights and positions.

[0140] In one embodiment, each set of support columns includes two parallel support columns, and multiple sets of support columns include two transverse support column groups and at least three longitudinal support column groups, such as... Figure 1 and Figure 4As shown, the two transverse support column groups include a first transverse support column group 11 and a second transverse support column group 12. Both the first transverse support column group 11 and the second transverse support column group 12 extend along the front-back direction of the work frame. The height of the second transverse support column group 12 is greater than the height of the first transverse support column group 11. The three longitudinal support column groups include a first longitudinal support column group 13, a second longitudinal support column group 14, and a third longitudinal support column group 15. The first longitudinal support column group 13 is located between the work platform 20 and the first transverse support column group 11. The second longitudinal support column group 14 is located between the first transverse support column group 11 and the second transverse support column group. The third longitudinal support column group 15 is located between the work platform 20 and the second transverse support column group 12. The first longitudinal support column group 13, the second longitudinal support column group 14, the third longitudinal support column group 15, the first transverse support column group 11, and the second transverse support column group 12 together define a first clearance space 40. The second longitudinal support column group 14 and the second transverse support column group 12 define a second clearance space 50.

[0141] like Figure 4 As shown, the work frame also includes a plurality of first adjustable casters 61, which are disposed on the lower surface of the first transverse support column group 11.

[0142] According to the embodiments of this disclosure, it should be noted that:

[0143] The first transverse support column group 11 and the second transverse support column group 12 both extend horizontally, while the first longitudinal support column group 13, the second longitudinal support column group 14, and the third longitudinal support column group 15 all extend vertically. By setting the first longitudinal support column group 13 and the third longitudinal support column group 15 on the first transverse support column group 11 and the second transverse support column group 12 respectively, and vertically connecting the second longitudinal support column group 14 between the first transverse support column group 11 and the second transverse support column group 12, a stable support frame structure can be formed while defining the first clearance space 40 and the second clearance space 50. It should be understood that the height of the second longitudinal support column group 14 is less than the height of the first longitudinal support column group 13 and the third longitudinal support column group 15, while the height of the first longitudinal support column group 13 and the third longitudinal support column group 15 are the same, thus allowing the work platform 20 to be supported at the same horizontal level. In addition, when the length of the work platform 20 is large, the longitudinal support column group may also include a fourth longitudinal support column group. The fourth longitudinal support column group may be set on the side of the third longitudinal support column group 15 away from the second longitudinal support column group 14. The fourth longitudinal support column group, the first longitudinal support column group 13 and the third longitudinal support column group 15 can more stably support the work platform 20.

[0144] Meanwhile, reinforcing columns 16 can be respectively set between the two supporting columns of the first transverse support column group 11 and between the two supporting columns of the second transverse support column group 12. The reinforcing columns 16 extend horizontally and connect the two parallel supporting columns at the same time, thereby making the structure of the support body 10 more robust.

[0145] The support columns can be made of metal square or rectangular tubes, which makes it easy to weld two adjacent support column groups together, and also makes it easy to install the first adjustable caster 61 on the first transverse support column group 11.

[0146] The distance between two support columns in the first transverse support column group 11 and the distance between two support columns in the second transverse support column group 12 can be the same as the width of the work platform 20, so as to ensure that the width of the work frame is consistent both above and below.

[0147] The first adjustable caster 61 is located on the lower surface of the first transverse support column group 11. The work frame can be moved by the rollers of the first adjustable caster 61. When the work frame moves to the target position, the support plate of the adjustable caster 61 can be adjusted so that the support plate gradually moves down and contacts the ground, thereby positioning the work frame and preventing the work frame from moving during operation.

[0148] In one embodiment, such as Figure 5 As shown, the work frame also includes multiple connecting columns 63 and multiple second adjustable casters 62. The multiple connecting columns 63 extend vertically and are detachably mounted on the lower surface of the second transverse support column group 12. The multiple second adjustable casters 62 are correspondingly mounted on the lower ends of the multiple connecting columns 63.

[0149] According to the embodiments of this disclosure, it should be noted that:

[0150] The connecting column 63 can be L-shaped, with its lateral part connected to the lower surface of the reinforcing column 16. In order to balance the force exerted by the working frame on the ground, the number of connecting columns 63 can be even, such as two or four connecting columns 63, and two or four connecting columns 63 are symmetrically arranged on the lower surface of the reinforcing column 16.

[0151] When the work frame moves close to the equipment and the side of the equipment facing the work frame has a protrusion, the connecting column 63 along with the second adjustable caster 62 on it can be removed to avoid the protrusion of the equipment and prevent interference between the two.

[0152] The second adjustable caster 62 has the same structure as the first adjustable caster 61, and its function will not be described in detail here.

[0153] In one embodiment, such as Figure 4 and Figure 6As shown, the support body 10 also includes a movable support 17, which is detachably disposed on the lower surface of the second transverse support column group 12 and is retractable in the vertical direction.

[0154] After the connecting column 63 and the second adjustable caster 62 on it are removed from the support frame, in order to enable the protruding part of the equipment to provide a certain support for the work frame, a movable support 17 is provided on the lower surface of the second transverse support column group 12. By using the height-adjustable movable support 17, the end of the work frame closest to the equipment can be supported by the equipment, avoiding the problem of insufficient support caused by the removal of the connecting column 63 and the second adjustable caster 62.

[0155] The movable support 17 may include a support plate and an adjusting bolt. The adjusting bolt is connected to one side of the support plate. The second transverse support column group 12 is provided with corresponding threaded holes. By rotating the adjusting bolt, the support plate can be moved closer to or away from the protruding part of the equipment. Thus, the end of the work frame that is closer to the equipment can be supported on the protruding part of the equipment by the movable support 17.

[0156] In one embodiment, such as Figure 6 As shown, the support body 10 also includes a first blocking part 18 and a second blocking part 19. The first blocking part 18 and the second blocking part 19 are spaced apart on one of the support columns of the second transverse support column group 12, and the movable support 17 is located between the first blocking part 18 and the second blocking part 19.

[0157] The first blocking part 18 and the second blocking part 19 can be configured as plate-shaped bodies. The first blocking part 18 and the second blocking part 19 are detachably mounted on one of the support columns of the second transverse support column group 12. In a specific example, the first blocking part 18 and the second blocking part 19 can be independently mounted on one of the support columns of the second transverse support column group 12, or they can be mounted on one of the support columns of the second transverse support column group 12 simultaneously by an intermediate component. For example, the first blocking part 18 and the second blocking part 19 can be fixedly connected to the intermediate rod, and the intermediate rod is connected to one of the support columns of the second transverse support column group 12 by a screw connection. Correspondingly, the threaded hole matching the adjusting bolt of the movable support 17 needs to pass through both one of the support columns of the second transverse support column group 12 and the intermediate rod.

[0158] By providing the first blocking part 18 and the second blocking part 19, the protruding part of the equipment can be prevented from hitting the movable support 17, thereby avoiding the movable support 17 from falling off due to the impact.

[0159] In one embodiment, such as Figure 5As shown, the work frame also includes a ladder 66, which is connected to the support body 10 and / or the work platform 20 for the user to go up and down. The ladder 66 has an inclination angle of 70° to 90°.

[0160] The ladder 66 can be connected to the support 10, the work platform 20, or both. The upper end of the ladder 66 corresponds to the opening 68 of the fence 22. When the user needs to work, he / she climbs the ladder 66 and enters the fence 22 through the opening 68. After the user finishes working, he / she exits the fence 22 through the opening 68 and walks to the ground through the ladder 66.

[0161] The tilt angle of the ladder 66 can be selected from any angle between 70° and 90°, that is, the tilt angle can be 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, or 90°. Using a higher tilt angle has two advantages: first, it helps to reduce the floor space occupied by the work frame. It can be understood that the smaller the tilt angle of the ladder 66, the larger the floor space occupied. Second, a higher tilt angle allows the user to climb up or down the ladder 66 in a near-vertical manner, which is more energy-efficient.

[0162] In one embodiment, such as Figure 5 As shown, the work frame also includes a first handrail 64 and a second handrail 65. The first handrail 64 is disposed on the first side of the platform 21, and the second handrail 65 is disposed on the second side of the platform 21. The first handrail 64 and the second handrail 65 are parallel to each other. At least a portion of the opening 68 is located between the first handrail 64 and the second handrail 65. The distance between the first handrail 64 and the second handrail 65 gradually increases from the lower end to the upper end of the work frame.

[0163] According to the embodiments of this disclosure, it should be noted that:

[0164] The first handrail 64 and the second handrail 65 can be arranged parallel to each other on both sides of the center line of the length direction of the platform 21, and the first handrail 64 and the second handrail 65 can be perpendicular to the platform 21. The lower end of the first handrail 64 and the lower end of the second handrail 65 can be connected to the platform 21, and the upper end of the first handrail 64 and the upper end of the second handrail 65 can be connected to the second railing 222.

[0165] The first handrail 64 and the second handrail 65 are provided so that when a user climbs to the top of the ladder 66 or has just come down from the top of the ladder 66, the ladder bars on both sides of the ladder 66 cannot provide a handhold for the user's hands. Therefore, by setting the first handrail 64 and the second handrail 65, a handhold can be provided for the user, making it safer to go up and down the ladder 66.

[0166] By setting the distance between the first handrail 64 and the second handrail 65 to gradually increase from the bottom to the top of the work frame, the size of the space around the opening 68 of the fence 22 can be increased, making it easier for users to enter. The distance between the first handrail 64 and the second handrail 65 can be between 600mm and 780mm. On the one hand, this can save external space and avoid interference. On the other hand, since the distance between the two ladder bars is generally around 600mm, the distance between the first handrail 64 and the second handrail 65 can also be the same as the distance between the two ladder bars, so that the lower ends of the first handrail 64 and the second handrail 65 are connected to the two ladder bars respectively. In a specific example, the first handrail 64 and the second handrail 65 can be divided into three sections. The distance between the lower section of the first handrail 64 and the lower section of the second handrail 65 can be 600mm. The distance between the middle section of the first handrail 64 and the middle section of the second handrail 65 can be incremental, that is, between 601-779mm. The distance between the upper section of the first handrail 64 and the upper section of the second handrail 65 can be 780mm.

[0167] In one embodiment, the length-to-width ratio of the work rack can be between 2.5:1 and 4:1. The larger the length-to-width ratio of the work rack, the easier it is to use in narrow spaces.

[0168] In one embodiment, such as Figure 5 As shown, a grounding post 67 can also be installed at the lower end of the support frame and connected to the equipment to be maintained through a grounding wire, thereby preventing users from getting electric shock and improving personnel safety.
