Description

Technical Field

[0001] The utility model relates to the technical field of desulfurization tower construction, in particular to an anti-corrosion construction auxiliary device. Background Art

[0002] Desulfurization tower is an important equipment in industrial flue gas treatment, mainly used to remove harmful gases such as sulfur dioxide in flue gas. Desulfurization tower is often affected by corrosion during operation, which not only affects the normal operation of the equipment, but also may cause environmental pollution. Coating anti-corrosion is a common method for desulfurization tower anti-corrosion. By applying anti-corrosion coating on the surface of the tower body, a protective film is formed to prevent the corrosive medium from directly contacting the tower body. Commonly used anti-corrosion coatings include epoxy resin, polyurethane, chlorinated rubber, etc.

[0003] The Chinese utility model patent with authorization announcement number CN219009861U proposes an anti-corrosion construction auxiliary device for the desulfurization absorption tower of a thermal power plant, which is convenient for moving the auxiliary device used for spraying the desulfurization tower, and convenient for firmly placing the auxiliary device after moving, thereby improving the stability of use, and convenient for lifting and lowering the auxiliary device, thus greatly facilitating the use of staff.

[0004] However, there are still some shortcomings in the use of the above-mentioned device: although the device provides a construction platform, its safety protection measures during high-altitude operations are not perfect, which makes workers face the risk of falling from heights during the construction process, especially when performing operations such as paint spraying. Since workers need to move and change postures, this risk is greatly increased. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-corrosion construction auxiliary device to address the defects of the prior art, which can ensure the safety of construction workers and prevent them from falling.

[0006] In order to solve the above technical problems, the utility model provides an anti-corrosion construction auxiliary device, including a lifting mechanism, a construction platform is arranged on the lifting mechanism, a circle of enclosure is arranged on the edge of the construction platform, a roller assembly is arranged on the top of the enclosure, a fixing assembly is fixedly arranged on the inside of the enclosure, a protective frame is arranged on the outside of the enclosure, the protective frame is arranged perpendicular to the enclosure, one end of the protective frame is rotatably connected to the outside of the enclosure, the other end of the protective frame is connected to the enclosure through a lifting rope, one end of the lifting rope is connected to the protective frame, and the other end of the lifting rope is connected to the fixing assembly through the roller assembly, thereby fixing the protective frame.

[0007] The utility model provides a protective frame on the outside of the enclosure, and the protective frame is fixed by a lifting rope and a fixing assembly, so as to avoid the risk of construction workers falling when spraying the desulfurization tower; in addition, when the protective frame is not needed, it can be retracted by the lifting rope so that the protective frame fits the enclosure and reduces the occupied space.

[0008] Furthermore, the fixing assembly comprises a hook, the sling is connected to the hook via a ring, and the ring is sleeved on the hook.

[0009] The lifting rope of the utility model is connected with the hook through the ring, and the connection is convenient, stable and reliable.

[0010] Furthermore, the fixing assembly includes a first hook, a second hook and a winding roller, the first hook is arranged below the second hook, the winding roller is arranged between the first hook and the second hook, and the suspension rope is directly connected to the second hook, or is connected to the first hook after passing around the winding roller.

[0011] The utility model provides a first hook, a second hook and a winding roller. When the lifting rope is directly connected to the second hook, the protective frame is arranged perpendicular to the enclosure. When it is necessary to reduce the occupation of the construction space by the protective frame, the lifting rope can be wound on the winding roller and then connected to the first hook, so that the protective frame can be rotated to different angles.

[0012] Furthermore, two roller assemblies are arranged in parallel, and the two roller assemblies are arranged close to the inner side and the outer side of the enclosure respectively.

[0013] The utility model provides two roller assemblies, through which the rope can unfold and retract the protective plate, and can prevent the rope from being worn due to friction with the enclosure during the process of winding and releasing the rope. In addition, there is rolling friction between the rope and the roller assembly, and the friction force is small, making it easier to unfold and retract the protective plate.

[0014] Furthermore, a rotating seat is fixedly arranged on the outer side of the enclosure near both ends, the protective frame is arranged between the two rotating seats, and the protective frame is rotatably connected to the rotating seat through a rotating shaft.

[0015] The utility model realizes the rotation connection between the protection frame and the enclosure by arranging two rotating seats.

[0016] Furthermore, a temporary support rod is arranged at the bottom of the rotating seat, and one end of the temporary support rod is rotatably connected to the rotating seat, so that the temporary support rod can rotate horizontally around the rotating seat, thereby supporting the protective frame.

[0017] The utility model can serve as a backup protection means by arranging a temporary support rod. When the first hook or the second hook is disconnected from the enclosure, or the ring is disconnected from the lifting rope, the temporary support rod can temporarily support the protection frame. When the protection frame needs to be used, the protection frame can be placed on the temporary support rod first, and then the lifting rope can be gradually retracted to adjust the angle of the protection frame, which is more convenient and labor-saving to use.

[0018] Furthermore, the temporary support rod is L-shaped.

[0019] The temporary support rod of the utility model is L-shaped, one end of the temporary support rod is rotatably connected to the rotating seat, and the other end can horizontally support the protective frame.

[0020] Furthermore, the protection frame includes a protection frame and a protection net, the protection frame is rectangular, and the protection net is arranged in the protection frame.

[0021] The beneficial effects of the utility model are as follows: the utility model arranges a protective frame on the outside of the enclosure, and the protective frame is fixed by a lifting rope and a fixing assembly, so as to avoid the risk of construction workers falling when spraying the desulfurization tower; in addition, when the protective frame is not needed, it can be folded up by the lifting rope, so that the protective frame is in close contact with the enclosure, reducing the occupied space.

[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0028] like Figure 1As shown, this embodiment provides an anti-corrosion construction auxiliary device, including a lifting mechanism and a construction platform 1 arranged on the lifting mechanism. Figure 1 The lifting mechanism is not shown in the figure, and the lifting mechanism is a prior art, and a hydraulic lift can be used. The construction platform 1 is rectangular, and four enclosures 2 are arranged at the edge of the construction platform 1. The four enclosures 2 are enclosed with each other, and a protective frame 4 is rotatably arranged on the outer side of the four enclosures 2. One end of the protective frame 4 is rotatably connected to the outer side of the enclosure 2, and the other end of the protective frame 4 is connected to the enclosure 2 through two suspension ropes 6, so that the protective frame 4 is fixed.

[0029] like Figure 2 , 4 As shown, a fixing assembly 5 and a roller assembly 8 are provided on the enclosure 2. The roller assembly 8 is provided at the top of the enclosure 2. The roller assembly 8 includes two mounting seats and a roller shaft. Both ends of the roller shaft are rotatably connected to the mounting seats. The suspension rope 6 is placed on the roller shaft. In this embodiment, two roller assemblies 8 are provided in parallel. The two roller assemblies 8 are arranged close to the inner side and the outer side of the enclosure 2, respectively, so as to avoid friction between the suspension rope 6 and the edge of the enclosure 2. In this embodiment, the construction platform 1 and the enclosure 2 can be made of stainless steel, and the construction platform 1 and the enclosure 2 can be connected by welding or bolts.

[0030] The fixing assembly 5 includes a first hook 501, a second hook 503 and a winding roller 502. The first hook 501 is arranged below the second hook 503, and the winding roller 502 is arranged between the first hook 501 and the second hook 503. The lifting rope 6 can be directly connected to the second hook 503, or connected to the first hook 501 through a ring after passing through the winding roller 502. When the lifting rope 6 is directly connected to the second hook 503, the protective frame 4 is arranged perpendicular to the fence 2. When it is necessary to reduce the occupation of the construction space by the protective frame 4, the lifting rope 6 can be wound on the winding roller 502 and then connected to the first hook 501, so that the protective frame 4 can be rotated to different angles.

[0031] like Figure 3 As shown, the protection frame 4 includes a protection frame and a protection net, the protection frame is rectangular, and the protection net is arranged inside the protection frame. Two rotating seats 3 are fixedly arranged on the outer side of the enclosure 2 near both ends by welding, and the protection frame 4 is arranged between the two rotating seats 3, and the protection frame 4 is rotatably connected to the rotating seat 3 through a rotating shaft.

[0032] A temporary support rod 7 is rotatably set at the bottom of the rotating seat 3. The temporary support rod 7 is L-shaped. The vertical part of the temporary support rod 7 is rotatably connected to the rotating seat 3. The horizontal part of the temporary support rod 7 is arranged under the protective frame 4 and can be used to temporarily support the two ends of the protective frame.

[0033] The working principle of the anti-corrosion construction auxiliary device is as follows: when the construction platform 1 is raised to a certain height, one end of the lifting rope 6 can be taken off the first lifting hook and wound out from the winding roller 502, and then the lifting rope 6 can be slowly released, and the lifting rope 6 can be connected to the second lifting hook, so that the protection frame 4 is unfolded to a horizontal state. When the angle of the protection frame 4 needs to be changed, one end of the lifting rope 6 is taken off from the second lifting hook, and after being wound along the winding roller 502 for a certain number of times, it is connected to the first lifting hook, thereby changing the angle of the protection frame 4. When an accident such as the lifting rope 6 breaking or the hook being damaged occurs, the anti-slip frame will be supported by the temporary support rod 7, thereby improving the protection capability of the anti-corrosion construction auxiliary device.

[0034] The embodiments described above are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, a person skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
