Description

Technical Field

[0001] The utility model relates to the technical field of chemical storage tank anti-corrosion devices, in particular to a safety anti-corrosion device for a large chemical storage tank. Background Art

[0002] Large chemical storage tanks are containers used to store liquid substances such as chemicals, solvents, and oils. In order to improve the corrosion resistance of chemical storage tanks, it is necessary to spray anti-corrosion coatings on the surface of chemical storage tanks through anti-corrosion devices. Existing anti-corrosion devices usually use a lifting device to move the working frame and the operator to the outside of the chemical storage tank. At this time, the operator can spray the coating on the surface of the chemical storage tank through a nozzle, which is convenient for improving the corrosion resistance of the chemical storage tank surface.

[0003] Patent specification CN212759245U discloses a paint spraying device for corrosion protection of large, non-standard chemical tanks. The device comprises a wall-mounted trolley, a mounting assembly, a windshield assembly, a paint spraying assembly, and an adjustment assembly. The wall-mounted trolley comprises a base plate, a mounting frame, and support rods. The mounting frame is vertically fixed to the base plate via the support rods. The mounting assembly comprises a mounting base, two L-shaped brackets, and two connecting rods. The windshield assembly comprises a windshield and a rotating connector. The paint spraying assembly comprises a nozzle, an infusion tube, and a paint storage tank. The nozzle is provided with a plurality of nozzles spaced evenly apart. The adjustment assembly comprises an adjustment rod, a plurality of fixing blocks, a sliding rod, and a fixing ring for fixing the nozzle. The adjustment rod is fixed with a plurality of fixing blocks, each having a slot provided at the center of the top surface of the fixing block. The sliding rod is fixed with a block that matches the slot, and the fixing ring is slidably connected to the sliding rod. This utility model can significantly reduce the workload of the operator while reducing the impact of natural wind on construction work at high altitudes, thereby improving overall construction efficiency.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned spray painting device for anti-corrosion construction of large non-standard storage tanks for chemical industry has the following problems: the device can change the windshield's windshield direction by rotating the windshield, thereby improving the windshield's windshield effect, but the pull rod and the windshield need to be moved at the same time when adjusting the windshield, and both hands need to be used at the same time to complete the adjustment of the windshield, which reduces the convenience of adjusting the windshield, thereby reducing the convenience of using the anti-corrosion device. In order to ensure the windshield effect, the windshield has a large area, so the arms need to extend out of the installation frame to rotate the windshield. When the operator's hands are far away from the side of the windshield, part of the body needs to be leaned forward and extended out of the installation frame, which can easily cause the operator's body to be unstable, increasing the probability of the operator falling out of the installation frame, thereby reducing the safety of the anti-corrosion device when in use.

[0005] In order to solve the above problems, this application proposes a large-scale chemical storage tank safety anti-corrosion device. Utility Model Content

[0006] To solve the problems raised in the above background technology. The utility model provides a large chemical storage tank safety anti-corrosion device, which can complete the direction adjustment of the windshield by simply moving the limit shaft upward and left and right. The operation is relatively convenient, thereby improving the convenience of using the device. At the same time, during operation, the operator's arms and body do not need to extend outside the working frame, reducing the risk of the operator falling, thereby improving the safety of the device when in use. Moreover, without affecting the work efficiency of the operator, it is convenient to block the paint blowing towards the operator through the shielding glass, reducing the probability of the paint falling on the operator's face, thereby further improving the safety of the device.

[0007] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a large-scale chemical storage tank safety and corrosion prevention device, comprising a working frame, two mounting seats fixedly provided on the side of the working frame, the interiors of the two mounting seats are rotatably connected to a windshield, two slide rails fixedly provided on one side of the working frame, the interiors of the two slide rails are provided with a hollow slider, the interiors of the two sliders are provided with a movable block, the interiors of the two movable blocks are fixed with a limit shaft, the tops of the two movable blocks are fixed with a limit spring, the tops of the two limit springs are respectively fixedly connected to the interiors of the two sliders, the sides of the two limit shafts are fixed with anti-slip pads, one side of the two sliders is hinged with a support rod, and one end of the two support rods is hinged to one side of the two windshields respectively.

[0008] As a preferred embodiment of the large chemical storage tank safety and corrosion prevention device of the present invention, the top ends of the two slide rails are provided with slide grooves, and the interiors of the two slide grooves are respectively slidably connected to the sides of the two sliders, so that the slide rails facilitate improving the stability of the sliders when moving.

[0009] As a preferred embodiment of the large chemical storage tank safety and corrosion prevention device of the present invention, movable grooves are provided inside the two sliders, and the interiors of the two movable grooves are respectively slidably connected to the sides of the two movable blocks, so that the sliders can easily drive the support rods to move.

[0010] As a preferred embodiment of the large chemical storage tank safety and corrosion prevention device of the present invention, a plurality of limiting holes are provided at the bottom ends of the two slide rails, and the side surfaces of the two limiting shafts are respectively fitted with the interiors of the corresponding two limiting holes, so that the limiting shafts facilitate limiting the slider.

[0011] As a preferred embodiment of the large chemical storage tank safety and corrosion prevention device of the present invention, the interiors of the two sliders are provided with connecting holes, and the interiors of the two connecting holes are respectively fitted with the sides of the two limiting shafts, so that the sliders facilitate improving the stability of the limiting shafts when they move.

[0012] As a preferred embodiment of the large-scale chemical storage tank safety and corrosion protection device of the present invention, two fixing rods are fixed at the bottom end of the working frame, and the top ends of the two fixing rods are provided with fixing frames. The bottom ends of the fixing frames are fixedly connected to the top ends of the two fixing rods respectively, and the fixing frames facilitate limiting the connecting frame.

[0013] As a preferred large-scale chemical storage tank safety anti-corrosion device of the present invention, a fixing groove is provided on the top of the fixing frame, a connecting frame is provided inside the fixing groove, and a shielding glass is fixed inside the connecting frame to block the spray paint from blowing towards the workers.

[0014] As a preferred large-scale chemical storage tank safety and corrosion protection device of the present invention, two bolts are threadedly connected to one side of the fixing frame, and a knob is fixed on one side of the two bolts. Two positioning holes are opened inside the connecting frame, and the two bolts pass through the two positioning holes respectively. The bolts facilitate fixing the fixing frame and the connecting frame together.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. When the wind shield needs to be rotated, the limit shaft is moved upward, so that the limit shaft is disengaged from the limit hole inside the slide rail, so that the slider loses its limit. At this time, the limit shaft is moved left and right, thereby driving the slider to move left and right, thereby driving the wind shield to rotate. When the direction of the wind shield is adjusted, the limit shaft is released, and the movable block is driven downward by the limit spring, so that the limit shaft enters the corresponding limit hole in the slide rail, so that the slider is limited and cannot move, thereby making the wind shield limited and cannot move. Therefore, the device only needs to move the limit shaft upward and left and right to complete the direction adjustment of the wind shield, which is more convenient to operate, thereby improving the convenience of using the device. At the same time, the operator does not need to extend his arms and body outside the working frame during operation, which reduces the risk of the operator falling, thereby improving the safety of the device when in use;

[0017] 2. The paint is blocked by the shielding glass to prevent the paint from falling directly on the face of the operator. The shielding glass is transparent glass so that it will not affect the operator's field of vision. When the shielding glass surface is adhered to a lot of paint and affects the transparency of the shielding glass, the knob is turned to drive the bolts out of the connecting frame, and the connecting frame is moved upward so that the connecting frame and the shielding glass are removed. A new shielding glass is replaced and the connecting frame is placed in the fixed frame. The knob is reversed to allow the bolts to enter the interior of the connecting frame, so that the connecting frame and the shielding glass are limited. When replacing the shielding glass, only the knob needs to be turned and the connecting frame needs to be moved, so that the shielding glass can be replaced quickly without affecting the work efficiency of the operator. Therefore, the device can easily block the paint blowing towards the operator through the shielding glass without affecting the work efficiency of the operator, thereby reducing the probability of paint falling on the operator's face, thereby further improving the safety of the device.

[0026] Example 1

[0027] like Figure 1-Figure 4 As shown;

[0028] Safety and corrosion protection device for large chemical storage tanks, including working frame.

[0029] The patent specification with the announcement number CN212759245U discloses a paint spraying device for the anti-corrosion construction of large non-standard storage tanks for chemical industry. In order to solve the existing problems existing in this prior art, as disclosed in the background technology above, "the device can change the wind shield direction of the wind shield by rotating the wind shield, thereby improving the wind shield effect of the wind shield. However, when adjusting the wind shield, the pull rod and the wind shield need to be moved at the same time, and two hands need to be used at the same time to complete the adjustment of the wind shield, which reduces the convenience of adjusting the wind shield, thereby reducing the convenience of using the anti-corrosion device. In order to ensure the wind shield effect, the wind shield has a large area, so the arm needs to be extended outside the installation frame to rotate the wind shield. When the operator's hand is far away from the side of the wind shield, it is necessary to lean forward and extend part of the body out of the installation frame, which easily causes the operator's body to be unstable, increasing the probability of the operator falling out of the installation frame, thereby reducing the safety of the anti-corrosion device when in use." In terms of combined use, this problem is obviously a problem that exists and is difficult to solve. Therefore, in order to solve this technical problem, a support rod and a limit shaft are added to this application document;

[0030] More specifically:

[0031] like Figures 1 to 4 As shown:

[0032] In combination with the above content: A large-scale chemical storage tank safety and corrosion prevention device includes a working frame 1, two mounting seats 2 are fixedly provided on the side of the working frame 1, and the interiors of the two mounting seats 2 are rotatably connected to a windshield 3, and two slide rails 4 are fixed on one side of the working frame 1, and the interiors of the two slide rails 4 are provided with hollow sliders 5, and the interiors of the two sliders 5 are provided with movable blocks 6, and the interiors of the two movable blocks 6 are fixed with limit shafts 7, and the tops of the two movable blocks 6 are fixed with limit springs 8, and the tops of the two limit springs 8 are respectively fixedly connected to the interiors of the two sliders 5, and the sides of the two limit shafts 7 are fixed with anti-slip pads 9, and one side of the two sliders 5 is hinged with a support rod 10, and one end of the two support rods 10 is hinged to one side of the two windshields 3 respectively.

[0033] In this embodiment: the operator stands inside the working frame 1 and moves the working frame 1 to the specified height of the side of the chemical storage tank through the lifting device. At this time, the operator can spray the anti-corrosion paint to the side of the chemical storage tank through the nozzle to improve the anti-corrosion performance of the chemical storage tank. When the external wind is strong, the wind is blocked by the two wind shields 3 to reduce the probability of the wind blowing away the paint sprayed from the nozzle and reduce the waste of spraying paint. When the wind shield 3 is at a large inclination angle to the wind direction, the wind shield effect of the wind shield 3 will decrease, and the limit shaft 7 will be moved upward, so that the limit shaft 7 will be disengaged from the limit hole inside the slide rail 4, causing the slider 5 to lose its limit. At this time, the limit shaft 7 is moved left and right, thereby driving the slider 5 to move left and right, thereby driving the support rod 10 to move left and right. When the support rod 10 moves left and right, it will drive the wind shield 3 to rotate. The stability of the windshield 3 during rotation is improved by the mounting seat 2. When the direction of the windshield 3 is adjusted, the limit shaft 7 is released, and the movable block 6 is driven downward by the limit spring 8, thereby driving the limit shaft 7 to move downward, so that the limit shaft 7 enters the corresponding limit hole in the slide rail 4, so that the slider 5 is limited and cannot move, thereby making the support rod 10 limited and cannot move, thereby making the windshield 3 limited and cannot move, completing the adjustment of the direction of the windshield 3, so that the device only needs to move the limit shaft 7 up and left and right to complete the direction adjustment of the windshield 3, which is more convenient to operate, thereby improving the convenience of using the device. At the same time, during operation, the operator's arms and body do not need to extend outside the working frame 1, reducing the risk of the operator falling, thereby improving the safety of the device during use.

[0034] In an optional embodiment, a sliding groove is formed at the top of each of the two slide rails 4 , and the interiors of the two sliding grooves are respectively slidably connected to the side surfaces of the two sliders 5 .

[0035] In this embodiment, the slide rail 4 is convenient for improving the stability of the slider 5 when it moves.

[0036] In an optional embodiment, movable grooves are provided inside the two sliders 5 , and the interiors of the two movable grooves are respectively slidably connected to the side surfaces of the two movable blocks 6 .

[0037] In this embodiment, the slider 5 facilitates the movement of the support rod 10 .

[0038] In an optional embodiment, a plurality of limiting holes are provided at the bottom ends of the two slide rails 4 , and the side surfaces of the two limiting shafts 7 are respectively fitted with the insides of the two corresponding limiting holes.

[0039] In this embodiment, the limiting shaft 7 is used to limit the slider 5 .

[0040] In an optional embodiment, connection holes are provided inside the two sliders 5 , and the insides of the two connection holes are respectively fitted with the side surfaces of the two limiting shafts 7 .

[0041] In this embodiment, the slider 5 is used to improve the stability of the limiting shaft 7 when it moves.

[0042] In an optional embodiment, two fixing rods 11 are fixedly provided at the bottom end of the working frame 1 , and fixing frames 12 are provided at the top ends of the two fixing rods 11 . The bottom ends of the fixing frames 12 are fixedly connected to the top ends of the two fixing rods 11 .

[0043] In this embodiment, the fixing frame 12 is convenient for limiting the connection frame 13 .

[0044] In an optional embodiment, a fixing groove is formed at the top of the fixing frame 12 , a connecting frame 13 is provided inside the fixing groove, and a shielding glass 14 is fixed inside the connecting frame 13 .

[0045] In this embodiment, the shielding glass 14 is convenient for shielding the spray paint from being blown toward the operator.

[0046] In an optional embodiment, one side of the fixing frame 12 is threadedly connected to two bolts 15 , one side of each bolt 15 is fixed with a knob 16 , and two positioning holes are provided inside the connecting frame 13 , and the two bolts 15 pass through the two positioning holes respectively.

[0047] In this embodiment, the bolts 15 facilitate fixing the fixing frame 12 and the connecting frame 13 together.

[0048] The working principle and use process of the utility model are as follows: the operator stands inside the working frame 1 and moves the working frame 1 to the specified height of the side of the chemical storage tank through the lifting device. At this time, the operator can spray the anti-corrosion paint to the side of the chemical storage tank through the nozzle, so as to improve the anti-corrosion performance of the chemical storage tank. When the external wind force is strong, the wind is blocked by the two wind shields 3 to reduce the probability of the wind blowing away the paint sprayed from the nozzle and reduce the waste of spraying paint. When the inclination angle of the wind shield 3 to the wind direction is large, the wind shield effect of the wind shield 3 will decrease, and the limit shaft 7 will be moved upward, so that the limit shaft 7 will be disengaged from the limit hole inside the slide rail 4, so that the slider 5 loses its limit. At this time, the limit shaft 7 is moved left and right, thereby driving the slider 5 to move left and right, thereby driving the support rod 10 to move left and right. When the support rod 10 moves left and right, it will drive the wind shield 3 to rotate, and the stability of the wind shield 3 during rotation is improved by the mounting seat 2. When the direction of the wind shield 3 is adjusted, the limit shaft 7 is released, and the movable block 6 is moved downward by the limit spring 8, thereby driving the limit shaft 7 to move downward, so that the limit shaft 7 enters the corresponding limit hole in the slide rail 4, so that the slider 5 is limited and cannot move, thereby making the support rod 10 limited and cannot move, thereby making the wind shield 3 limited and cannot move, completing the adjustment of the direction of the wind shield 3, so that the device only needs to move up and left and right to complete the direction adjustment of the wind shield 3, which is more convenient to operate, thereby improving the convenience of using the device, and at the same time, there is no need for the operator to stretch his arms and body out of the workbench during operation. The outside of the frame 1 reduces the risk of workers falling, thereby improving the safety of the device when in use. The wind shield 3 can reduce the wind force blowing from the outside to the paint spraying area, thereby reducing the probability of the paint being blown to the worker's face by the wind. However, when the external wind force is strong, part of the paint will still be blown to the worker's face, reducing the safety of the device. When the device is in use, when part of the paint is blown by the wind, causing the paint to be blown to the worker's face, the shielding glass 14 is used to shield the paint, thereby preventing the paint from falling directly on the worker's face, thereby improving the safety of the device. The shielding glass 14 is transparent glass, so that it will not affect the worker's field of vision. When a lot of paint adheres to the surface of the shielding glass 14, affecting the transparency of the shielding glass 14, At this time, the knob 16 is turned several times, thereby driving the bolt 15 to turn several times, so that the bolt 15 is separated from the connecting frame 13. At this time, the connecting frame 13 is moved upward, so that the connecting frame 13 is separated from the fixing frame 12, so that the shielding glass 14 is removed, and a new shielding glass 14 is replaced, and the connecting frame 13 is placed in the fixing frame 12. The knob 16 is reversed several times, thereby driving the bolt 15 to turn several times, so that the bolt 15 enters the interior of the connecting frame 13, so that the connecting frame 13 is restricted, thereby limiting the shielding glass 14. When replacing the shielding glass 14, it is only necessary to turn the knob 16 and move the connecting frame 13, so that the shielding glass 14 is replaced more quickly, thereby not affecting the work efficiency of the staff, thereby making the device work without affecting the work efficiency of the staff.The shielding glass 14 can be used to block the paint sprayed toward the workers, thereby reducing the probability of the paint sprayed onto the workers' faces and further improving the safety of the device.

[0049] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
