[0040] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0041] Giant tanks have a wide range of uses and can be used for batching, material stirring, storage, etc. However, due to their large volume and high height, when workers operate or inspect the pipes, valves, and instruments installed on the tank body, they need to set up a temporary ladder beside the giant tank, and the workers carry out operations through the temporary ladder. The stability of the temporary ladder is poor and the height from the ground is relatively high. When workers operate through the ladder, there is a risk of falling from a height. In addition, when it is necessary to operate or inspect the pipes, valves, and instruments on multiple giant tanks, the workers also need to move the temporary ladder, which is not only time-consuming and laborious, but also has low efficiency.

[0042] In view of this, please refer to Figures 1 to 9 , the operation platform and mixing system of the giant tank provided in the embodiments of the present utility model can solve the above problems, and will be described in detail below.

[0043] Refer to Figure 1 , the operation platform of the giant tank includes a platform board 1, vertical support rods 2, an inclined ladder 3, and a guardrail 4. Through this operation platform, workers can carry out a series of high-altitude operations around the giant tank 6. At the same time, this operation platform can also be applied to other objects with relatively large heights, such as roof decoration and water tower demolition.

[0044] The platform board 1 is arranged on the vertical support rods 2. Through the support of the vertical support rods 2, the platform board 1 is at a certain height from the ground. The platform board 1 surrounds the outer wall of the giant tank 6, and workers can operate around the giant tank 6 on the platform board 1. The inclined ladder 3 is arranged on the side of the platform board 1, and the upper end of the inclined ladder 3 is connected to or flush with the platform board 1, and the lower end of the inclined ladder 3 is connected to the ground. Workers can reach the platform board 1 through the inclined ladder 3. At the same time, guardrails 4 are arranged around the platform board 1 and on both sides of the inclined ladder 3 to play a protective role and prevent personnel from falling from the inclined ladder 3 or the platform board 1 and causing safety problems. Workers have high stability when operating on the platform board 1. Compared with working on a temporary ladder, there is higher safety protection, more sufficient activity space, lower operation limitations, and good comfort for workers.

[0045] Refer to Figure 1 And Figure 2 , since the axis of the giant tank 6 is generally vertical, the platform board 1 is arranged perpendicular to the axis of the giant tank 6, so that the platform board 1 is in a horizontal state; the platform board 1 is a flat plate, and limiting through holes 10 are opened on the flat plate. The giant tank 6 is limited through the limiting through holes 10. The shape of the limiting through holes 10 is adapted to the shape of the giant tank 6, and the size of the limiting through holes 10 is slightly larger than that of the giant tank 6 to facilitate the placement of the giant tank 6. Here, the size of the limiting through holes 10 refers to the diameter, length, width, etc. For example, if the giant tank 6 is cylindrical, the limiting through holes 10 are circular holes; if the giant tank 6 is a quadrangular prism, the limiting through holes 10 are rectangular or rhombic.

[0046] When the number of the giant tanks 6 is relatively large, multiple giant tanks 6 can be centrally arranged in the same space, and then a plurality of limit through holes 10 are formed in the platform plate 1. The multiple limit through holes 10 respectively limit the multiple giant tanks 6, so that a single working platform can perform corresponding operations on the multiple giant tanks 6, solving the problem that the temporary ladder needs to be moved repeatedly many times at present, greatly saving the physical strength and working time of the staff, and improving the working efficiency.

[0047] Of course, in order to prevent the staff from slipping on the platform plate 1, anti-slip patterns or anti-slip patterns can be etched on the upper surface of the platform plate 1.

[0048] The platform plate 1 is used to support the operation of the staff, so it needs to have a certain strength. The platform plate 1 can be made of steel plate, aluminum alloy plate, hard plastic plate or wooden board, etc.

[0049] In this embodiment, the platform plate 1 is a flat plate. In other embodiments, the platform plate 1 can be in other forms such as a curved plate or a grid plate.

[0050] The vertical support rod 2 is used to support the platform plate 1, so the vertical support rod 2 needs to be connected to the platform plate 1. The platform plate 1 can be connected to the top of the vertical support rod 2 or to the rod wall of the vertical support rod 2.

[0051] When the platform plate 1 is connected to the top of the vertical support rod 2, any one of welding, screw connection, bolt connection and mortise-tenon connection can be adopted between the vertical support rod 2 and the platform plate 1; if welded connection is adopted, both the platform plate 1 and the vertical support rod 2 are made of metal; if screw connection or bolt connection is adopted, corresponding threaded holes need to be formed in both the platform plate 1 and the vertical support rod 2, and at the same time, a connecting portion connected to the platform plate 1 needs to be provided at the top of the vertical support rod 2, or the vertical support rod 2 and the platform plate 1 are connected by using an angular connecting piece 20 as shown in Figure 3 The angular connecting piece 20 has the advantage of increasing the contact area between the platform plate 1 and the vertical support rod 2, and can better transfer the pressure on the platform plate 1 to the vertical support rod 2; when mortise-tenon connection is adopted, mortise eyes need to be formed in the platform plate 1 and tenons corresponding to the mortise eyes need to be made at the top end of the vertical support rod 2.

[0052] When the platform plate 1 is connected to the rod wall of the vertical support rod 2, in one implementation manner, that is, using the angular connecting piece 20 for connection, the angular connecting piece 20 is fixed on the rod wall of the vertical support rod 2, and then the platform plate 1 is placed on the vacant side of the angular connecting piece 20.

[0053] In addition, the vertical support rod 2 can be of solid structure or hollow structure, and there are also various shapes of the vertical support rod 2. In this embodiment, the vertical support rod 2 is a hollow square tube made of stainless steel; in other embodiments, the vertical support rod 2 can also be a round tube, an angle steel, an I-beam, etc. In addition to having a fixed height, the vertical support rod 2 can also be a telescopic rod, which can be extended and retracted in the height direction to adjust the platform plate 1 to different height positions of the giant tank 6 to meet the needs of special operations; in this embodiment, the bottom end of the vertical support rod 2 is connected to a hydraulic cylinder, and the hydraulic cylinder is fixed on the ground. When hydraulic oil is injected into the hydraulic cylinder, the piston of the hydraulic cylinder jacks up the vertical support rod 2. On the contrary, when the hydraulic oil in the hydraulic cylinder is drained, the piston of the hydraulic cylinder drives the vertical support rod 2 to descend. The piston of the hydraulic cylinder is fixedly welded to the vertical support rod 2.

[0054] When the number of vertical support rods 2 is small, or the compressive capacity of the platform plate 1 is poor, the platform plate 1 is prone to deformation and shaking, which affects the workers located on the platform plate 1. Therefore, in order to increase the strength of the platform plate 1, a reinforcing member 5 is provided below the platform plate 1 to improve the compressive capacity of the platform plate 1 through the reinforcing member 5 and reduce the deformation amplitude of the platform plate 1.

[0055] Reference Figure 4 , the reinforcing member 5 includes a transverse support rod 50 and a longitudinal support rod 51. The transverse support rod 50 is connected to the longitudinal support rod 51, and the longitudinal support rod 51 is connected to the vertical support rod 2. The transverse support rod 50 and the longitudinal support rod 51 are connected in a criss-cross manner to support the platform plate 1. In this embodiment, both the transverse support rod 50 and the longitudinal support rod 51 are hollow square steel tubes; the longitudinal support rod 51 is connected to the vertical support rod 2 and the longitudinal support rod 51 is connected to the transverse support rod 50 by welding.

[0056] Since the platform plate 1 is at a certain height from the ground, when workers need to work on the platform plate 1, they generally cannot directly climb onto the platform plate 1 from the ground. Therefore, an inclined ladder 3 is provided on the side of the platform plate 1, and the workers climb onto the platform plate 1 through the inclined ladder 3. The upper part of the inclined ladder 3 is connected to or flush with the platform plate 1, and the lower part of the inclined ladder 3 is connected to the ground.

[0057] Reference Figure 5 , the inclined ladder 3 is formed by overlapping multiple steps 30. The two sides of the step 30 are inclined overlapping frames, and the steps 30 are sequentially connected to the overlapping frames. Specifically, the step 30 is a right-angled steel plate, and the overlapping frame is welded into a right-angled triangle by square steel. The left and right ends of the right-angled steel plate are welded to the hypotenuse of the right-angled triangle. Of course, the step 30 and the overlapping frame can also be formed in other forms, as long as the shape of the inclined ladder 3 is in the shape of the step 30, it belongs to the protection scope of this embodiment.

[0058] For convenience of setting and cost saving in manufacturing, this embodiment also provides another form of inclined ladder 3.

[0059] Referring to Figure 6 , the main body of the inclined ladder 3 is an inclined flat plate 31 arranged obliquely. Below the inclined flat plate 31 is a right-angle bracket, and the inclined flat plate 31 is fixed on the inclined surface of the right-angle bracket. Specifically, the right-angle bracket is welded into a right triangle by angle steel, and the inclined flat plate 31 is a steel plate. The steel plate is placed on the inclined sides of two relatively arranged right triangles and then welded together to form a stable inclined ladder 3. To prevent people from slipping when walking on the inclined flat plate 31, an anti-slip structure is provided on the upper surface of the inclined flat plate 31; the anti-slip structure includes anti-slip lines, anti-slip patterns, and welded anti-slip strips, such as transverse welding of threaded steel bars on the surface of the inclined flat plate 31.

[0060] Of course, for people to walk more labor-saving and safely, the inclination angle of the connecting line of the inclined surfaces where the steps 30 are located or the inclined flat plate 31 should not be too large. Generally, the inclination angle range is 10 - 40°; in this embodiment, the inclination angle is 15°.

[0061] To further ensure the safety of the staff during operation, a platform guardrail 40 is provided around the platform plate 1 and an inclined ladder guardrail 41 is provided on the left and right sides of the inclined ladder 3. Whether it is the platform guardrail 40 or the inclined ladder guardrail 41, generally, it is composed of vertical retaining bars and retaining bar connecting rods. The retaining bar connecting rods are connected to multiple vertical retaining bars to form an integral body. Such as Figure 7 , a retaining bar connecting rod is arranged at the top of multiple vertical retaining bars, and the bottom ends of the vertical retaining bars are connected to the platform plate 1 or the inclined ladder 3; another example is Figure 8 , by arranging multiple retaining bar connecting rods at different heights, the multiple retaining bar connecting rods connect the vertical retaining bars together. This structure has better stability compared to a single retaining bar connecting rod.

[0062] Specifically, the retaining bar connecting rods and vertical retaining bars of the platform guardrail 40 and the inclined ladder guardrail 41 are all hollow circular aluminum alloy tubes. The retaining bar connecting rods are welded to the vertical retaining bars, and the vertical retaining bars are welded to the platform plate 1, the inclined flat plate 31 / step 30.

[0063] It should be noted that multiple support legs are provided at the bottom of the giant tank 6 in the above embodiments. The support legs are fixed to the ground to ensure the stability of the giant tank 6. The limit through holes 10 on the platform plate 1 only accommodate the giant tank 6 and do not form radial support for the giant tank 6.

[0064] In summary, the working platform provided by the embodiment of the present utility model is composed of a platform board 1, vertical support rods 2, an inclined ladder 3, a platform guardrail 40, an inclined ladder guardrail 41, a horizontal support rod 50, and a longitudinal support rod 51. The staff is located on the platform board 1 to operate around the giant tank 6, which not only has a good working space but also has good comfort. With the protection of the platform guardrail 40 and the inclined ladder guardrail 41, the operators are not at risk of falling from a height. Compared with operating through a temporary climbing ladder, the working platform of this embodiment does not require manual moving, saving time and effort.

[0065] The embodiment of the present utility model also provides a stirring system, which is a specific application scenario of the above-mentioned working platform. The stirring system includes the above-mentioned working platform, a giant tank 6, an operation center 8, a pipeline 60 connected to the giant tank 6, and a stirring mechanism 7 provided on the giant tank 6.

[0066] Specifically, various pipelines 60 with different purposes are generally connected to the giant tank 6. Various valves and detection instruments are provided on the pipelines 60. The valves control the flow inside the pipelines 60, and the instruments detect the state data inside the pipelines 60. In addition, in order to facilitate recording the data detected by the instruments and controlling the valves on the pipelines 60, an operation center 8 is also provided on the platform board 1. The operation center 8 is communicatively connected to each instrument and valve. Of course, the instruments and valves described here can all be communicatively controlled. For example, the valve is an electromagnetic control valve, the instrument is a temperature sensor / pressure sensor, and the operation center 8 is programmed by a PLC and connected to a touch screen. The staff can operate on the touch screen to complete the opening and closing of the valves and the viewing / exporting of the detection data of the instruments. In addition to being connected to the pipeline 60, a stirring mechanism 7 is also provided on the giant tank 6 to stir the materials inside the giant tank 6 through the stirring mechanism 7.

[0067] Reference Figure 9 , the stirring mechanism 7 includes a driving member 70, a rotating shaft 71, and stirring rods 72. The stirring rods 72 are distributed on the outer wall of the rotating shaft 71 and fixedly connected to the rotating shaft 71. The lower sections of the stirring rods 72 and the rotating shaft 71 are both located inside the giant tank 6. The upper end of the rotating shaft 71 passes through the top of the giant tank 6 and is connected to the driving member 70. When the driving member 70 works, it drives the rotating shaft 71 to rotate, and then drives the stirring rods 72 to stir the materials. In order to scrape off the materials adhered to the inner wall of the giant tank 6, a scraping plate 73 is also connected to the end of the stirring rod 72 to scrape off the materials on the inner wall of the giant tank 6 through the scraping plate 73.

[0068] Specifically, the driving member 70 is a servo motor, which is communicatively connected to the operation center 8. The output shaft of the servo motor is connected to the rotating shaft 71 through a shaft connector.

[0069] A ball bearing is arranged between the rotating shaft 71 and the giant tank 6. The outer ring of the ball bearing is fixed to the top of the giant tank 6, and the inner ring of the ball bearing is sleeved and fixed on the rotating shaft 71, so that the rotating shaft 71 can rotate smoothly.

[0070] Of course, the fixed position and fixing method of the driving member 70 and the additional limit of the rotating shaft 71 can be provided by setting a corresponding bracket on the top of the giant tank 6. The bracket can be easily realized by existing technical means and is regarded as existing technology, which will not be repeated here.

[0071] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
