[0061] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0062] The work platform can usually include a ladder and a work platform. The work platform has a certain height above the ground, such as 1.5 to 2 meters. Of course, the height is not limited to this. The ladder can be installed on the ground at one end and on the work platform at the other end, so that users can climb up and down the work platform. The work platform provides a working space for users to complete corresponding work on it.

[0063] In the related art, due to the high height of the work platform, its center of gravity is increased, and also due to the uneven ground, there is a problem of the work platform tilting or even falling when the user walks or works on the work platform, which not only seriously affects the safety of the user, but also endangers the safety of personnel and facilities around the work platform.

[0064] In order to solve at least one of the above technical problems, the present disclosure provides a work frame, including a support body, a work platform and a connection structure. The work platform is arranged on the support body, and the connection structure is arranged on the support body and / or the work platform, and the connection structure is used to connect the work frame to other objects. Through the solution of the present disclosure, at least one of the above technical problems is effectively solved.

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

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

[0067] The work platform 20 is mainly used for users to work thereon. The work platform 20 may include structures such as a plate-like body or a mesh-like body. For example, the work platform 20 may be a flat plate structure, or an iron mesh structure with supporting capabilities. The shape of the work platform 20 can be designed according to the specific usage scenario. For example, in some places with narrow spaces, the work platform 20 can be set to a rectangular shape.

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

[0069] The connecting structure 30 can have different setting positions. The connecting structure 30 can be set on the support body 10, that is, the connecting structure 30 is connected to the support body 10. The connecting structure 30 can also be set on the working platform 20, that is, the connecting structure 30 is connected to the working platform 20. The connecting structure 30 can also be set on the support body 10 and the working platform 20 at the same time. In other words, the connecting structure 30 is connected to the support body 10 and the working platform 20 at the same time. At the same time, the connecting structure 30 is also connected to other objects.

[0070] The other objects here are objects that can provide stable support for the work frame and prevent it from tilting or falling, and they themselves have the characteristic of being difficult to move. For example, in different usage scenarios, the other objects can be walls of buildings in construction sites, other objects can also be equipment in manufacturing plants, etc. In the following embodiments, the other objects are all described by taking the equipment in manufacturing plants as an example.

[0071] When the work stand needs to be used, the work stand is moved close to the equipment, and then the connecting structure 30 is connected to the equipment, so that the work stand and the equipment are reliably connected, thereby preventing the work stand from tilting or falling.

[0072] In some embodiments, the number of connecting structures 30 can be multiple, for example, the number of connecting structures 30 can be two. Taking the connection between the connecting structure 30 and the working platform 20 as an example, the two connecting structures 30 can be arranged on both sides of the working platform 20 in a symmetrical or asymmetrical manner. Of course, the number of connecting structures 30 is not limited to this, and can also be three or four, etc. The present disclosure does not specifically limit the number.

[0073] According to the embodiments of the present disclosure, the support body 10 and / or the work platform 20 are connected to the equipment via 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 also be attached to the equipment via the connecting structure 30, so that a reliable connection can be formed between the work frame and the equipment, thereby preventing the work frame from tilting or tipping over, which is beneficial to ensuring the safety of personnel on the work frame, and also can avoid the problem of damage to facilities or personnel around the work frame due to the tipping over of the work frame.

[0074] In one embodiment, Figure 1 and Figure 2 As shown, the connecting structure 30 includes a first connecting member 31 and a second connecting member 32, the first connecting member 31 extends along a first direction x and is connected to the support body 10 and / or the work platform 20, the first connecting member 31 is provided with a first connecting portion, and the first connecting portion is used to connect to the equipment, the second connecting member 32 extends along a second direction y and is connected to the first connecting member 31, the second connecting member 32 is provided with a second connecting portion, and the second connecting portion is used to connect to the equipment, wherein the first direction x and the second direction y are not parallel.

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

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

[0077] Among them, 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, connected by bolts passing through the through holes and cooperating with nuts) located on the first connecting member 31 and the second connecting member 32. When it is a threaded hole, it can be connected to the threaded hole by a bolt on the equipment; furthermore, the first connecting part and the second connecting part can also be at least one of the clip-on structures, for example, the first connecting part and the second connecting part can be one of the mortise and tenon structures; in addition, the first connecting part and the second connecting part can also be one of the positioning columns or positioning holes, for example, a prismatic positioning column can be provided on the first connecting member 31, and a positioning hole cooperating with the prismatic positioning column can be provided on the second connecting member 32, so as to realize the connection between the first connecting member 31 and the second connecting member 32.

[0078] The number of the first connection parts on the first connection member 31 may be one or two or more, and the number of the second connection parts on the second connection member 32 may be one or two or more, which is not specifically limited in the embodiments of the present disclosure.

[0079] The first direction x here can be perpendicular to the vertical plane of the length direction of the working platform 20, and 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 the first direction x and the second direction y can be in different planes, depending on the specific shape of the equipment. For example, when the equipment is roughly a rectangular parallelepiped or a cylinder, the first connecting part and the second connecting part can be located on the top surface of the equipment. At this time, the first connecting part and the second connecting part are coplanar.

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

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

[0082] The third connecting member 33 can be a rod-shaped body, a plate-shaped body or the like, and the third connecting member 33 serves to connect the first connecting member 31 and the second connecting member 32 to the support body 10 and / or the working platform 20, wherein the third connecting member 33 can also be connected to the support body 10 and / or the working platform 20 by means of the threaded structure, mortise and tenon structure, positioning column or positioning hole or the like in the above-mentioned embodiments.

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

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

[0085] As in the above-mentioned embodiment, the first connection hole 311, the second connection hole 321 and the third connection hole of the embodiment of the present disclosure may be threaded holes or through holes. According to the different forms of the connection holes, bolts, or bolts and nuts may be selected for connection.

[0086] By using 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, so that the work frame can be used in different positions. For example, after repairing a piece of equipment in a manufacturing plant, the first connecting member 31 and the second connecting member 32 are removed from the repaired equipment, and the work frame can be moved to the next equipment to be repaired, and the first connecting member 31 and the second connecting member 32 are installed on the equipment to be repaired.

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

[0088] Taking into account factors such as the flatness of the ground at the site of use (for example, the ground is uneven), the manufacturing and assembly errors of the work frame, and the difficulty in accurately controlling the relative position of the work frame and the equipment, at least one of the first connection hole 311, the second connection hole 321, and the third connection hole is set as a long strip hole. For example, when the ground is uneven, the depression in the ground will reduce the relative height of the work frame. When the third connection hole is a through hole and a bolt and a nut are used to match the third connection hole, the height of the connection structure 30 relative to the ground can be changed by adjusting the position of the bolt and the nut relative to the length direction of the third connection hole. In this way, it can be ensured that the first connection member 31 and the second connection member 32 are located on the top surface of the equipment, so that the first connection member 31 and the second connection member 32 can be accurately connected to the equipment. For another example, the top surfaces of multiple devices are often not at the same height. The height of the connection structure 30 can be easily adjusted through the third long connection hole. When in use, you can first ensure that the positions of the first connection member 31 and the second connection member 32 are both higher than the top surface of the device, and then adaptively lower the height of the connection structure 30 according to different devices. In this way, the work frame can be adapted to devices of different heights, and it can also avoid the connection structure 30 from colliding with some devices with higher top surfaces. For another example, some devices have threaded holes corresponding to the first connection hole 311 and the second connection hole 321. Due to the manufacturing accuracy of the device, the threaded holes in the first direction x and the threaded holes in the second direction y may be difficult to adapt (align) the first connection hole 311 and the second connection hole 321. The long first connection hole 311 and the second connection hole 321 can compensate for the manufacturing accuracy of the threaded holes on the device, so that the first connection hole 311 and the second connection hole 321 are aligned with the threaded holes on the device.

[0089] In other embodiments, the third connecting hole may also be a non-elongated hole, and the hole opened on the support body 10 and / or the working platform 20 for cooperating with the third connecting hole is set as an elongated hole, so that the height adjustment of the connecting structure can also be achieved.

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

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

[0092] The platform 21 is mainly used for users to work on it. As in the above embodiment, the platform 21 includes structures such as a plate-like body or a mesh-like body. For example, the platform 21 can be a flat plate structure, or an iron mesh structure with supporting capacity. The shape of the platform 21 can be designed according to the specific usage scenario. For example, in some places with narrow space, the platform 21 can be set to a rectangular shape. In the present embodiment, the platform 21 is a rectangular flat plate structure.

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

[0094] Among them, the fence 22 at least partially surrounds the platform 21, which means that the fence 22 can surround multiple sides of the platform 21 from a position higher than the platform 21. The multiple sides here also change adaptively according to the shape of the platform 21. When the platform 21 is circular, the fence 22 surrounds most 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 the user 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 frame are generally adults, whose height is usually between 1.5m and 1.9m. Therefore, in order to facilitate the user's arms to cross the fence 22 for work while 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 than two. For example, the number of fences 22 can be one. From a top view, the fence 22 presents a U-shaped integrated structure. The number of fences 22 can also be three. Three fences 22 can be spliced ​​into a U-shaped structure. At this time, the three fences 22 are split structures.

[0097] In the embodiment of the present disclosure, the fence 22 can be connected to the platform 21 in a hinged manner, and the fence 22 is a three-part structure. The three fences 22 can be hinged to the platform 21 through hinges respectively. When the three fences 22 are flipped to the top of the platform 21 and are perpendicular to the platform 21, the fences 22 can be detachably fixed by screwing or clamping, so as to ensure 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 to the bottom of the platform 21 and are 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. Therefore, 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 a platform 21 is required but no fence 22 is required (for example, when the space at 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, Figure 1 As shown, the fence 22 includes a first railing 221, a second railing 222, a first vertical rod 223 and a second vertical rod 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 a side of the first railing 221 away from the platform 21 and at least partially surrounds the platform 21. The first vertical rod 223 is arranged on the platform 21 and simultaneously connects the first railing 221 and the second railing 222 on the first side of the platform 21. The second vertical rod 224 is arranged on the platform 21 and simultaneously connects the first railing 221 and the second railing 222 on the second side of the platform 21.

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

[0100] The first railing 221 and the second railing 222 are crossbars, 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. At the same time, the first railing 221 can be an integrated structure or a split structure. Taking the platform 21 as a rectangle as an example, the shape of the first railing 221 is a U-shaped structure when viewed from the top. At this time, the number of the first railing 221 can be one, two or three. It can be understood that when the number of the first railing 221 is one, The first railing 221 is an integrated structure. When the number of the first railings 221 is two or three, the first railings 221 are a split structure. When the number of the first railings 221 is two, one of the first railings 221 is a straight line, and the other first railing 221 is an L-shape, 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. At this time, the first railing 221 can also be an integrated structure, or a split structure composed of multiple sections spliced ​​together to form a C-shape.

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

[0102] The distance between the first railing 221 and the second railing 222 can be roughly equal to the distance between the first railing 221 and the platform 21, so that the gap formed between the first railing 221 and the second railing 222 can be roughly the same size as the gap formed between the first railing 221 and the platform 21, thereby ensuring that the different gaps above and below can effectively prevent people from falling.

[0103] The first vertical rod 223 is arranged perpendicular to the platform 21. The first vertical rod 223 can be connected to the first railing 221 and the second railing 222 by welding, screwing or clamping. The function of the first vertical rod 223 is to form a grid-shaped fence 22 with the first railing 221 and the second railing 222, which can reduce the manufacturing materials and weight of the work frame while ensuring that people are not likely to fall. The first vertical rod 223 is arranged on the platform 21, which means that the first vertical rod 223 is connected to the platform 21. In combination with the above embodiment, the first vertical rod 223 can be hinged to the platform 21 through a hinge. Of course, in other embodiments, the first railing 221 can also be hinged to the platform 21, and the first vertical rod 223 is not connected to the platform 21.

[0104] The structure of the second vertical rod 224 may be the same as that of the first railing 221 , except that the first vertical rod 223 and the second vertical rod 224 are arranged at different positions, and their structures will not be described in detail herein.

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

[0106] like Figure 1 As shown, the platform 21 here is a rectangle, for example, illustrating the first side where the first vertical rod 223 is located and the second side where the second vertical rod 224 is located. The platform 21 has two long sides along its length direction, and the two vertical surfaces where the long sides are located are the first side and the second side, wherein the first side and the second side are opposite to each other.

[0107] The third connecting member 33 in the above embodiment may be disposed on the first vertical rod 223 or the second vertical rod 224 , and the third connecting member 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 rod 223 and the second vertical rod 224 may be tubular structures, such as square tubes or round tubes, which is helpful to reduce the weight of the work frame and can also be conveniently connected by welding.

[0109] The distance between the first railing 221 and the second railing 222 may be 450 to 550 mm, which can effectively prevent people from falling, save materials of the fence 22 and reduce weight, and also facilitate users to work (such as repairing the upper part of equipment) through the gap between the first railing 221 and the second railing 222.

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

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

[0112] The third rod 2223 can be detachably connected to the first rod 2221 and the second rod 2222 by means of screw connection, clamping connection, etc.

[0113] In one embodiment, Figure 1 As shown, the working platform 20 further includes a tool box 23 , which is detachably disposed on at least one of the first rod 2221 , the second rod 2222 and the third rod 2223 .

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

[0115] As the name implies, the tool box 23 is mainly used to place tools and other items. When the user needs a large number of tools, he can hold some of the tools in his hands and put some in the tool box 23, which is convenient for the user to work. According to the specific number of tools required, the size of the tool box 23 or the number of tool boxes 23 can be used to meet the needs. When there are many tools, a large-capacity tool box 23 or multiple small-capacity tool boxes 23 can be used.

[0116] Disposing the tool box 23 in a detachable manner on at least one of the first rod 2221, the second rod 2222 and the third rod 2223 means that the tool box 23 can be selectively disposed on one of the first rod 2221, the second rod 2222 and the third rod 2223 as needed. When the user works on different sides of the platform 21, the tool box 23 is placed on the rod facing the user, so that the user can take and put tools conveniently. In addition, when the number of tool boxes 23 is large, more than one tool box 23 can be selectively placed on two rods or three rods.

[0117] For example, the tool box 23 can be hung on the first railing 221 or the second railing 222 by a hook or a groove opening downward, so as to facilitate taking and placing the tool box 23.

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

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

[0120] The baffle 24 is a plate-shaped structure. The arrangement path of the baffle 24 may 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 can be 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 tying them 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, that is, another railing is 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 both at least partially surround the periphery of the platform 21, the third railing is arranged close to the platform 21, and the baffle 24 can be connected to the third railing.

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

[0124] Among them, like the first railing 221 and the second railing 222 in the above embodiments, the baffle 24 here can also adopt an integrated structure or a split structure, which will not be repeated here.

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

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

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

[0128] The rebound door 25 refers to a door that has a tendency to always move toward the initial position, that is, when there is no external force, the rebound door 25 will always remain in the initial position and remain motionless. Under the action of external force, the rebound door 25 can leave the initial position. When the external force is cancelled, the rebound door 25 will automatically return to the initial position. The rebound door 25 can be connected to the first vertical rod 223 or the second vertical rod 224 by a torsion spring or a rebound hinge. Under the action of external force, the rebound door 25 can apply a compression force to the torsion spring or the rebound hinge, thereby leaving the initial position. When the external force is cancelled, the rebound door 25 can return to the initial position by relying on the restoring force of the torsion spring or the rebound hinge.

[0129] like Figure 1 As shown, at this time, the rebound door 25 is in the open position, and when the rebound door 25 rotates 90 degrees, the rebound door 25 is in the closed position (that is, the initial position mentioned above), or, when the rebound door 25 moves to be parallel to the first rod 2221 or the second rod 2222, the rebound door 25 is in the open position, and when the rebound door 25 moves to be perpendicular to the first rod 2221 or the second rod 2222, the rebound door 25 is in the closed position.

[0130] When the user stands in the fence 22 and prepares to open the rebound door 25, sufficient space needs to be left to avoid interference between the user's body and the rebound door 25 during the door opening process. The length of the space (the distance between the third rod 2223 and the rebound door 25 when they are in the open position) should not be less than 450mm, and its maximum length can be set as needed, for example, it can be 1000mm, 2000mm, 3000mm, etc.

[0131] In the embodiment of the present disclosure, through the normally closed function of the rebound door 25, the rebound door 25 and the fence 22 can form a four-sided closed structure, that is, the rebound door 25 blocks a part of the opening 68, and the user will not fall through the opening 68 even if he slips when working on the platform 21, thereby ensuring the safety of the user.

[0132] In other embodiments, the fence 22 may further include a limiting portion (not shown in the figure), which is used to prevent the rebound door 25 at the closed position from moving in a direction away from the open position, that is, the limiting portion can avoid the problem of the rebound door 25 opening in the opposite direction under the action of external force when the rebound hinge or the torsion spring fails, thereby ensuring the safety of people on the platform 21, wherein the limiting portion can be a limiting column or a limiting protrusion or other structure arranged on the first railing 221, the second railing 222, the first vertical rod 223 or the second vertical rod 224, one end of the limiting portion is arranged on the first railing 221, the second railing 222, the first vertical rod 223 or the second vertical rod 224, and the other end of the limiting portion extends toward the rebound hinge or the torsion spring.

[0133] In one embodiment, Figure 4 As shown, the fence 22 further includes a locking member 26, which is connected to the first railing 221 or the second railing 222 and is used to lock the rebound door 25 in the open position.

[0134] In some cases, the rebound door 25 needs to be kept in the open position at all times. For example, when parts or tools need to be continuously transported to the platform 21, the rebound door 25 can be locked in the open position by the locking member 26, which can facilitate the user to transport parts or tools and avoid frequent opening or closing of the rebound door 25.

[0135] Among them, the locking piece 26 can be any suitable structure. For example, the locking piece 26 can be a magnet installed on the first railing 221 or the second railing 222. The rebound door 25 can be kept in the open position by adsorbing the magnet. It should be understood that the adsorption force of the magnet should be greater than the rebound force of the rebound door 25. The locking piece 26 can also adopt a latch. Accordingly, a socket that cooperates with the latch is provided on the rebound door 25. The rebound door 25 can also be locked in the open position by inserting the latch into the socket.

[0136] In one embodiment, Figure 4 As shown, the support body 10 includes multiple groups 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 the first interference object, and the second avoidance space 50 is used to avoid the second interference object, wherein the position of the first interference object is higher than the position of the second interference object.

[0137] According to the embodiments of the present 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 disposed on a plurality of groups of support columns.

[0139] Many equipment in manufacturing plants are not completely regular in shape. There are usually some protruding parts on the upper and lower parts of the equipment. In order to make the work rack as close to the equipment as possible without interference from the protruding parts of the equipment, multiple groups of support columns can be arranged to form a first avoidance space 40 and a second avoidance space 50, which can avoid the protruding parts of the lower part of the equipment from interfering with the work rack. The first avoidance space 40 and the second avoidance space 50 of different heights can avoid interfering objects of different heights and positions.

[0140] In one embodiment, each group of support columns includes two parallel support columns, and the plurality of groups of support columns include two transverse support column groups and at least three longitudinal support column groups. 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, the first transverse support column group 11 and the second transverse support column group 12 both extend along the front-to-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, and 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 arranged between the working platform 20 and the first transverse support column group 11, the second longitudinal support column group 14 is arranged between the first transverse support column group 11 and the second transverse support column, and the third longitudinal support column group 15 is arranged between the working 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 jointly define a first avoidance space 40, and the second longitudinal support column group 14 and the second transverse support column group 12 define a second avoidance space 50.

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

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

[0143] The first transverse support column group 11 and the second transverse support column group 12 are both extended in the horizontal direction, and the first longitudinal support column group 13, the second longitudinal support column group 14 and the third longitudinal support column group 15 are all extended in the vertical direction. By arranging 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 avoidance space 40 and the second avoidance 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, and the height of the first longitudinal support column group 13 is the same as the height of the third longitudinal support column group 15, so that the working platform 20 can be supported at the same horizontal height. In addition, when the length of the working platform 20 is large, the longitudinal support column group can also include a fourth longitudinal support column group. The fourth longitudinal support column group can be arranged 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 and the first longitudinal support column group 13 and the third longitudinal support column group 15 can more stably support the working platform 20.

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

[0145] The support columns can be made of metal square tubes, which facilitates welding two adjacent support column groups together and also facilitates installing the first adjustable caster 61 on the first transverse support column group 11 .

[0146] Among them, 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 working platform 20, so as to ensure that the upper and lower widths of the working frame are consistent.

[0147] The first adjustable caster 61 is arranged on the lower surface of the first lateral support column group 11. The work frame can be moved by the roller 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, so as to realize the positioning of the work frame and prevent the work frame from moving during work.

[0148] In one embodiment, Figure 5 As shown, the work frame also includes a plurality of connecting columns 63 and a plurality of second adjustable casters 62. The plurality of connecting columns 63 extend in the vertical direction and are detachably arranged on the lower surface of the second lateral support column group 12. The plurality of second adjustable casters 62 are arranged one by one at the lower ends of the plurality of connecting columns 63.

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

[0150] The connecting column 63 can be L-shaped, and its transverse part is connected to the lower surface of the reinforcing column 16. In order to balance the force of the work frame on the ground, the number of connecting columns 63 can be an even number. For example, the connecting columns 63 can be two, four, etc., and two or four connecting columns 63 are symmetrically arranged on the lower surface of the reinforcing column 16.

[0151] When the work stand moves close to the equipment and the equipment has a raised portion on the side facing the work stand, the connecting column 63 and the second adjustable caster 62 thereon can be removed to avoid the raised portion 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 functions will not be described in detail here.

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

[0154] When the support frame removes the connecting column 63 and the second adjustable caster 62 thereon, in order to enable the raised part of the equipment to play a certain supporting role on the work frame, a movable support 17 is set on the lower surface of the second horizontal support column group 12. By using the height-adjustable movable support 17, the end of the work frame close to the equipment can be supported by the equipment, avoiding the problem of insufficient supporting force caused by removing the connecting column 63 and the second adjustable caster 62 thereon.

[0155] Among them, the movable support 17 may include a support plate and an adjusting bolt, one side of the support plate is connected to the adjusting bolt, and the second transverse support column group 12 is provided with a corresponding threaded hole. By rotating the adjusting bolt, the support plate can be moved closer to or away from the raised part of the equipment, so that the end of the working frame close to the equipment can be supported on the raised part of the equipment through the movable support 17.

[0156] In one embodiment, Figure 6 As shown, the support body 10 also includes a first blocking portion 18 and a second blocking portion 19 , which 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 portion 18 and the second blocking portion 19 .

[0157] Among them, the first blocking portion 18 and the second blocking portion 19 can be set as a plate-like body, and the first blocking portion 18 and the second blocking portion 19 are detachably arranged on one of the support columns of the second transverse support column group 12. In a specific example, the first blocking portion 18 and the second blocking portion 19 can be respectively and independently arranged on one of the support columns of the second transverse support column group 12, or can be simultaneously arranged on one of the support columns of the second transverse support column group 12 through an intermediate component. For example, the first blocking portion 18 and the second blocking portion 19 can be fixedly connected to the middle rod, and the middle rod is screwed to one of the support columns of the second transverse support column group 12. Accordingly, the threaded hole matching the adjustment bolt of the movable support 17 needs to pass through one of the support columns of the second transverse support column group 12 and the middle rod at the same time.

[0158] The first blocking portion 18 and the second blocking portion 19 can be provided to prevent the raised portion of the device from hitting the movable support 17, thereby preventing the movable support 17 from falling off due to the impact.

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

[0160] The ladder 66 can be connected to the support body 10, or to the work platform 20, or to both the support body 10 and the work platform 20 at the same time, and the upper end of the ladder 66 corresponds to the opening 68 of the fence 22. When the user needs to work, he climbs up the ladder 66 and enters the fence 22 through the opening 68. When the user finishes the work, he walks out of the fence 22 through the opening 68 and walks to the ground through the ladder 66.

[0161] The inclination angle of the ladder 66 can be selected as any angle between 70° and 90°, that is, the inclination angle can be 71°, 72°, 73°, 74°, 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, 90°. Using a higher inclination angle is beneficial to reducing the footprint of the work frame. It can be understood that the smaller the inclination angle of the ladder 66, the larger the footprint. Secondly, at a higher inclination angle, the user's body can climb up or down the ladder 66 in a nearly upright manner, which can save more effort.

[0162] In one embodiment, Figure 5 As shown, the work frame also includes a first handrail 64 and a second handrail 65, the first handrail 64 is arranged on the first side of the platform 21, and the second handrail 65 is arranged on the second side of the platform 21, and the first handrail 64 and the second handrail 65 are parallel, and at least a portion of the opening 68 is located between the first handrail 64 and the second handrail 65, wherein the distance between the first handrail 64 and the second handrail 65 gradually increases in the direction extending from the lower end to the upper end of the work frame.

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

[0164] The first handrail 64 and the second handrail 65 can be arranged in parallel on both sides of the center line of the platform 21 in the length direction, 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 the user climbs to the upper part of the ladder 66 or just comes down from the top of the ladder 66, the ladder bars on both sides of the ladder 66 are difficult to provide a foothold for the user's hands. Therefore, by providing the first handrail 64 and the second handrail 65, a foothold 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 in the direction extending from the lower end to the upper end of the work frame, the space size outside the opening 68 of the fence 22 can be increased to facilitate user entry. The distance between the first handrail 64 and the second handrail 65 can range from 600mm to 780mm. On the one hand, it 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 kept the same as the distance between the two ladder bars, so that the lower end of the first handrail 64 and the lower end of the second handrail 65 are respectively connected to the two ladder bars. In a specific example, the first armrest 64 and the second armrest 65 can be divided into three sections. The distance between the lower section of the first armrest 64 and the lower section of the second armrest 65 can be 600mm, the distance between the middle section of the first armrest 64 and the middle section of the second armrest 65 can be incremental, that is, between 601-779mm, and the distance between the upper section of the first armrest 64 and the upper section of the second armrest 65 can be 780mm.

[0167] In one embodiment, the ratio of the length to the width of the work frame may be in the range of 2.5:1 to 4:1. When the ratio of the length to the width of the work frame is larger, the work frame is more suitable for use in narrow spaces.

[0168] In one embodiment, Figure 5 As shown, a grounding column 67 may be provided at the lower end of the support frame and connected to the equipment to be repaired via a grounding wire, thereby preventing electric shock to the user and improving the safety of the personnel.
