Description

Technical Field

[0001] The utility model relates to the field of auxiliary equipment for storage tank construction, in particular to a movable working platform for storage tank construction. Background Technique

[0002] At present, large cylindrical storage tanks (with diameters up to 10 meters or even dozens of meters or more) are built in many places. Such cylindrical storage tanks are composed of several arc-shaped steel plates spliced together. Since the welding accuracy of current welding robots cannot meet the accuracy requirements of some storage tanks, many storage tanks are still welded together manually by welders. In order to facilitate the workers to weld two arc-shaped steel plates together, the current method is to build a scaffold around the steel plates and then remove the scaffold after the workers complete the welding operation. Although building the scaffold facilitates the workers to carry out the welding operation, building and removing the scaffold will consume a lot of time, and a large number of workers are also required to carry out the operation during the process of building and removing the scaffold. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a movable working platform for storage tank construction. By combining the use of hanging brackets, fixed frames, rigid pulleys, flexible support rollers, cantilever rods and guide frames, an operating platform that can move for operation is assembled on the steel plate, and there is no need to build a scaffold for welding operation, which is more convenient to operate.

[0004] The technical solution adopted by the utility model is as follows:

[0005] A movable working platform for storage tank construction includes a hanging bracket, a fixed frame, a guide frame, a rigid pulley, a flexible support roller and an operation cage. The fixed frame is arranged on the hanging bracket, the rigid pulley is slidably arranged on the fixed frame, the hanging bracket is provided with a cantilever rod, the cantilever rod is provided with a guide frame, the cantilever rod is perpendicular to the hanging bracket, the flexible support roller is arranged on the guide frame, the guide frame is perpendicular to the fixed frame, there are no less than 2 fixed frames, each fixed frame is provided with a rigid pulley, there are no less than 2 guide frames, and each guide frame is provided with a flexible support roller.

[0006] The operation process of this kind of working platform is as follows. The rigid pulley is used to contact the top of the steel plate, while the flexible support roller is used to contact the side wall of the steel plate. The function of the rigid pulley is to provide sliding support, and the function of the flexible support roller is to closely adhere to the side wall of the steel plate. When the rigid pulley slides and closely adheres to the top of the steel plate, and the flexible support roller closely adheres to the side wall of the steel plate, the steel plate, the hanging bracket, the cantilever rod, and the guiding frame enclose a rectangular frame. There are two stress points on this rectangular frame, which are respectively the contact point between the rigid pulley and the steel plate and the contact point between the flexible support roller and the steel plate. Due to the functions of the rigid pulley and the flexible support roller, the entire hanging bracket can slide stably on the steel plate, and the hanging bracket only moves on the steel plate when it is pushed by an external force (this external force can be from a worker outside the operation cage or other equipment). When the hanging bracket moves on the steel plate, the flexible support roller contacts the side wall of the steel plate, and there is a large frictional force between the flexible support roller and the side wall of the steel plate, which can ensure that the entire hanging bracket does not slide on the steel plate.

[0007] In this kind of working platform, the flexible support roller is located between the steel plate and the operation cage, while the cantilever rod is located between the operation cage and the rigid pulley. When welding operations are carried out, the operator is inside the operation cage to perform welding operations on the steel plate.

[0008] Specifically, in this kind of working platform, since the flexible support roller always closely adheres to the side wall of the steel plate and the flexible support roller has a certain degree of scalability, when the hanging bracket has a certain yaw and sway on the steel plate, the flexible support roller can still closely adhere to the side wall of the steel plate, thereby ensuring that the entire working platform does not slip off the steel plate.

[0009] In summary, this kind of working platform forms a movable working platform on the steel plate by combining the use of a hanging bracket, a fixed frame, a rigid pulley, a flexible support roller, a cantilever rod, and a guiding frame. There is no need to build a scaffolding for welding operations, and the operation is more convenient.

[0010] Optionally, the operation cage is a square operation cage, and the operation cage is connected to the cantilever rod and the hanging bracket.

[0011] Using a square operation cage, and the operation cage is connected to the cantilever rod and the hanging bracket. In this way, it is equivalent to having two ends of the operation cage in a fixed state, which can ensure good stability of the entire operation cage on the hanging bracket and improve the safety of the operators inside the operation cage.

[0012] Optionally, the fixed frame is parallel to the cantilever rod, and the guiding frame is perpendicular to the hanging bracket.

[0013] Optionally, the fixed frames are in a parallel and non-contact state.

[0014] There are two specific fixing frames, which are parallel and non - contacting with each other. Rigid pulleys are rotatably installed on both fixing frames, and the rigid pulleys are made of metals such as stainless steel.

[0015] Optionally, it further includes an anti - falling rod, the anti - falling rod is arranged on the hanging bracket, and the fixing frame is located between the anti - falling rod and the cantilever rod.

[0016] Optionally, the anti - falling rod is parallel to the cantilever rod.

[0017] Optionally, the anti - falling rod is perpendicular to the hanging bracket.

[0018] Optionally, there are multiple anti - falling rods, and the anti - falling rods are parallel to each other.

[0019] Specifically, when this kind of working platform is in use, the steel plate is located between the anti - falling rod and the cantilever rod. In this way, when the rigid pulley accidentally slips off the steel plate, since the two sides of the fixing frame are the cantilever rod and the anti - falling rod respectively, whether the steel plate is stuck between the fixing frame and the cantilever rod or between the anti - falling rod and the fixing frame, it can ensure that the entire working platform will not fall from the steel plate, thus ensuring the safety of the operators in the operation cage.

[0020] Optionally, the hanging bracket is a planar hanging bracket.

[0021] The beneficial effects of the present utility model are: By combining the use of a hanging bracket, a fixing frame, a rigid pulley, a flexible support roller, a cantilever rod and a guiding frame, an operation platform that can move for operation is assembled on the steel plate. There is no need to build a scaffolding for welding operations, and the operation is more convenient. Brief Description of the Drawings

[0025] To make the above - mentioned objects, features and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model is given in conjunction with the drawings.

[0026] In the following description, many specific details are set forth in order to provide a thorough understanding of the present utility model. However, the present utility model may also be implemented in other ways different from those described herein. Those skilled in the art may make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0027] As shown in the attached Figure 1 and the attached Figure 2 figures, a mobile working platform for storage tank construction includes a hanging bracket, a fixed frame 4, a guiding frame 7, a rigid pulley 3, a flexible support roller 8, and an operation cage 5. The fixed frame 4 is arranged on the hanging bracket. The rigid pulley 3 is slidably arranged on the fixed frame 4. The hanging bracket is provided with a cantilever rod 6. The guiding frame 7 is arranged on the cantilever rod 6. The cantilever rod 6 is perpendicular to the hanging bracket. The flexible support roller 8 is arranged on the guiding frame 7. The guiding frame 7 is perpendicular to the fixed frame 4. There are at least 2 fixed frames 4, and each fixed frame 4 is provided with a rigid pulley 3. There are at least 2 guiding frames 7, and each guiding frame 7 is provided with a flexible support roller 8.

[0028] The working process of this working platform is as follows: The rigid pulley 3 is used to contact the top of the steel plate 1, while the flexible support roller 8 is used to contact the side wall of the steel plate 1. The function of the rigid pulley 3 is to provide sliding support, and the function of the flexible support roller 8 is to closely adhere to the side wall of the steel plate 1. When the rigid pulley 3 slides and closely adheres to the top of the steel plate 1, and the flexible support roller 8 closely adheres to the side wall of the steel plate 1, the steel plate 1, the hanging bracket, the cantilever rod 6, and the guiding frame 7 enclose a rectangular frame. There are two stress points on this rectangular frame, which are respectively the contact point between the rigid pulley 3 and the steel plate 1 and the contact point between the flexible support roller 8 and the steel plate 1. Due to the functions of the rigid pulley 3 and the flexible support roller 8, the entire hanging bracket can slide stably on the steel plate 1, and the hanging bracket only moves on the steel plate 1 when it is pushed by an external force (this external force can be from a worker outside the operation cage 5 or other equipment). When the hanging bracket moves on the steel plate 1, the flexible support roller 8 contacts the side wall of the steel plate 1, and there is a large frictional force between the flexible support roller 8 and the side wall of the steel plate 1, which can ensure that the entire hanging bracket does not slide on the steel plate 1.

[0029] In this working platform, the flexible support roller 8 is located between the steel plate 1 and the operation cage 5, and the cantilever rod 6 is located between the operation cage 5 and the rigid pulley 3. When welding operations are carried out, the operating worker is inside the operation cage 5 to perform welding operations on the steel plate 1.

[0030] Specifically, in this type of working platform, since the flexible support roller 8 always closely adheres to the side wall of the steel plate 1 and the flexible support roller 8 has a certain degree of telescopicity, when the hanging bracket undergoes a certain amount of yaw and sway on the steel plate 1, the flexible support roller 8 can still closely adhere to the side wall of the steel plate 1, thereby ensuring that the entire working platform will not slip off the steel plate 1 and fall.

[0031] In summary, by combining the use of the hanging bracket, the fixing frame 4, the rigid pulley 3, the flexible support roller 8, the cantilever rod 6, and the guiding frame 7, this type of working platform forms an operating platform that can move and operate on the steel plate 1. There is no need to erect a scaffolding for welding operations, and the operation is more convenient.

[0032] Specifically, in this type of working platform, the flexible support roller can be made of rubber or other flexible materials.

[0033] As shown in the Figure 1 and the Figure 2 attached drawings, the operation cage 5 is a square operation cage 5, and the operation cage 5 is connected to the cantilever rod 6 and the hanging bracket.

[0034] By adopting a square operation cage 5 and connecting the operation cage 5 to the cantilever rod 6 and the hanging bracket, it is equivalent to having two ends of the operation cage 5 in a fixed state, which can ensure good stability of the entire operation cage 5 on the hanging bracket and improve the safety of the operators inside the operation cage 5.

[0035] As shown in the Figure 1 and the Figure 2 attached drawings, the fixing frame 4 is parallel to the cantilever rod 6, and the guiding frame 7 is perpendicular to the hanging bracket.

[0036] As shown in the Figure 1 and the Figure 2 attached drawings, the fixing frames 4 are in a parallel and non-contact state.

[0037] Specifically, there are two fixing frames 4, and the two fixing frames 4 are in a parallel and non-contact state. Rigid pulleys 3 are rotatably installed on both fixing frames 4, and the rigid pulleys 3 are made of metals such as stainless steel.

[0038] As shown in the Figure 1 and the Figure 2 attached drawings, it further includes an anti-falling rod 9. The anti-falling rod 9 is arranged on the hanging bracket, and the fixing frame 4 is located between the anti-falling rod 9 and the cantilever rod 6.

[0039] As shown in the Figure 1 and the Figure 2 attached drawings, the anti-falling rod 9 is parallel to the cantilever rod 6.

[0040] As shown in the Figure 1 and the Figure 2As shown, the anti-falling rod 9 is perpendicular to the hanging bracket.

[0041] As shown in the appendix Figure 1 and the appendix Figure 2 As shown, there are multiple anti-falling rods 9, and the anti-falling rods 9 are parallel to each other.

[0042] Specifically, when this kind of working platform is in use, the steel plate 1 is located between the anti-falling rod 9 and the cantilever rod 6. In this way, when the rigid pulley 3 accidentally slips off the steel plate 1, since the two sides of the fixing frame 4 are respectively the cantilever rod 6 and the anti-falling rod 9, whether the steel plate 1 is stuck between the fixing frame 4 and the cantilever rod 6 or between the anti-falling rod 9 and the fixing frame 4, it can ensure that the entire working platform will not fall from the steel plate 1, thus ensuring the safety of the operators in the operation cage 5.

[0043] As shown in the appendix Figure 1 and the appendix Figure 2 As shown, the hanging bracket is a planar hanging bracket.
