Description

Technical Field

[0001] The invention belongs to the technical field of steel structure manufacturing, in particular to a rust removal device for manufacturing color steel structures. Background Art

[0002] A large number of building steel structures are used when constructing buildings and bridges and roads. Building steel structures are prone to oxidation reactions with oxygen and water vapor in the air to produce rust in storage rooms. The cross-section of the steel structure is usually rectangular and circular. The steel structures can be connected and fixed by threads or welding. The current steel structure rust removal device usually needs to fix the steel structure first, and then use the rust removal motor to drive the rust removal wheel to rotate to remove the rust from the steel structure. However, this method is prone to incomplete rust removal during the rust removal process, and the steel structure needs to be constantly moved, which increases the difficulty of rust removal.

[0003] The existing commonly used rust removal devices include sandblasting rust removal machines, but this type of sandblasting rust removal machine requires manual operation. The operator puts on protective clothing and manually performs blasting work. However, the efficiency of manual rust removal is low, and the rust removal effect is determined by the operator's technical experience, so the rust removal effect is not stable. If encountering hot weather, the rust removal personnel may also suffer from heatstroke due to the sealing of the protective clothing. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides a rust removal device for color steel structure manufacturing, which solves the problem that the efficiency of manual rust removal is low. The rust removal effect is determined by the technical experience of the operator, so the rust removal effect is not stable. If encountering hot weather, the rust removal personnel may also suffer from heatstroke due to the sealing of the protective clothing.

[0005] The technical solution adopted by the present invention to solve its technical problems is: the rust removal device for color steel structure manufacturing described in the present invention comprises a splicing device, and the left and right sides of the outer surface of the splicing device are symmetrically provided with external connecting plates, and the inner wall of the external connecting plate is fixedly connected to a rotating motor on the side away from the splicing device, and the output shaft of the rotating motor is rollingly connected to a short transmission belt, and the splicing device comprises a vertical side plate, and the upper part of the inner wall of the vertical side plate is evenly provided with through-turning openings, and the upper part of the inner wall of the vertical side plate is rotatably connected to an adjustment rod through the through-turning opening, and the outer wall of the adjustment rod A long transmission belt is rollingly connected to the middle part of the surface, and a rust removal device is fixedly connected to the middle part of the lower surface of the long transmission belt. Pressurizing devices are symmetrically arranged on the left and right sides of the outer surface of the vertical side plate. Before using the device to remove rust from the color steel, the convex push plate of the large-capacity cylinder is first rotated to the lowest position, and the upper surface of the convex push plate is filled with sandblasting solution. Then the color steel is inserted into the interior of the splicing device, and the vertical side plates on both sides are pulled according to the actual width of the color steel. The pull rod is adjusted for telescopic adjustment to ensure that the color steel is inside the splicing device and does not contact the device inside the splicing device.

[0006] Preferably, the pressurizing device includes a large-capacity cylinder, a torque motor is fixedly connected to the axis center of the bottom of the inner wall of the large-capacity cylinder, a telescopic sleeve is fixedly connected to the outer surface of the torque motor output shaft, a convex push plate is fixedly connected to the top of the telescopic sleeve, and a threaded groove is opened on the upper part of the inner wall of the large-capacity cylinder, and the rotating motors on both sides and the torque motor inside the pressurizing device are started, and the rotating motor controls the adjustment rods on both sides to rotate through the short transmission belt, and the adjustment rods drive the long transmission belt to rotate, thereby making the rust removal device on the lower surface of the long transmission belt move in the horizontal plane. When the torque motor is working, the output shaft of the torque motor controls the convex push plate to spirally rise on the inner wall of the large-capacity cylinder through the telescopic sleeve, and the convex push plate squeezes and transports the sandblasting solution to the inside of the mobile sliding shell through the transport hollow plate. At this time, the telescopic sleeve is elongated, and the connection relationship between the torque motor and the convex push plate is continued to be maintained.

[0007] Preferably, the rust removal device includes a movable sliding shell, the upper surface of the movable sliding shell is fixedly connected to an external clamping plate, the front and rear sides of the upper surface of the external clamping plate are evenly provided with rotating screws, the upper part of the inner wall of the movable sliding shell is slidably connected to a transport hollow plate, the front and rear sides of the upper part of the inner wall of the movable sliding shell are symmetrically provided with adapter plugs, the outer surface of the adapter plug is symmetrically provided with folding partitions on the left and right sides away from one end of the inner wall of the movable sliding shell, the lower part of the inner wall of the movable sliding shell is provided with an adjustment nozzle, the sandblasting solution discharged from the pressurizing device enters the adapter plug through the transport hollow plate, and is then sprayed to the bottom through the adjustment nozzle. On the outer surface of the color-coated steel, during the movement of the rust removal device, the two sides of the outer surface of the transfer plug plate push the folding partitions, and the inner wall of the movable sliding shell slides along the outer surface of the transport hollow plate. Due to the blocking effect of the folding partitions, during the movement of the movable sliding shell, the sandblasting solution discharged by the pressurizing device will not leak from the side of the transport hollow plate. Because the rust removal device is clamped on the lower surface of the long transmission belt through the external clamping plate, the long transmission belt can control the rust removal device to reciprocate, and cooperate with the spraying effect of the sandblasting solution under the action of pressure. The sandblasting solution sprayed by the rust removal device will spray away the rust on the outer surface of the color-coated steel swept directly below.

[0008] Preferably, there are two folding partitions, and the upper and lower sides of the outer surface of the folding partition are fixedly connected to the inner wall of the transport hollow plate. The outer surface of the adapter plate extends to the interior of the transport hollow plate away from one end of the inner wall of the movable sliding shell, and the inner wall of the external splint is clamped with the lower part of the outer surface of the long transmission belt. The two ends of the transport hollow plate extend to the interior of the large-capacity cylinders on the left and right sides respectively. The greatest advantage of this device is that it can replace manual rust removal and remove rust from the outer surface of rusty long strips of color steel. Since the rotating motor and the torque motor are controllable, the stability of the device during rust removal movement can be guaranteed, so that the device can accurately remove rust from the outer surface of the color steel, thereby improving the efficiency of rust removal and the stability of rust removal effect.

[0009] Preferably, a side of the outer surface of the large-capacity cylinder away from the torque motor is fixedly connected to a side of the outer surface of the vertical side plate, and the side of the convex push plate is threadedly connected to the upper part of the inner wall of the large-capacity cylinder through a threaded groove. The upper part of the inner wall of the large-capacity cylinder is filled with rust removing sand liquid, and the bottom of the inner wall of the torque motor is fixedly connected to an external wire. If rust is removed by high-pressure sandblasting solution, during the rust removal process, rust and sandblasting solution will diffuse into the surrounding air, thereby causing environmental pollution and causing damage to the operator's body. Therefore, manual rust removal requires wearing protective clothing to perform rust removal work, while the device can isolate the removed rust and the scattered sandblasting solution through a relatively sealed vertical side plate, thereby greatly reducing environmental pollution.

[0010] Preferably, both ends of the adjustment rod extend to the outside of the vertical side plate, both sides of the outer surface of the adjustment rod are rotatably connected to the inner wall of the vertical side plate, the number of the external plates is four, and one end of the external plate close to the splicing device is fixedly connected to the outer surface of the vertical side plate, and the upper part of the inner wall of the short transmission belt is rotatably connected to one end of the outer surface of the adjustment rod. The device can adjust the width of the vertical side plate according to different models and widths of color steel bars, ensuring that the device can completely cover the color steel bars, increasing the versatility of the device, and avoiding the problem that the color steel bars are too wide, the device cannot be used, and the practical performance of the device is poor.

[0011] Preferably, the adjustment nozzle comprises a filling block, an inner transfer tube is evenly arranged on the lower part of the outer surface of the filling block, the top of the inner transfer tube extends to the inside of the adapter plate, the upper part of the outer surface of the inner transfer tube is fixedly connected to the inner wall of the adapter plate, the bottom end of the inner transfer tube is fixedly connected to the injection head, the filling block comprises a half-sectioned cylinder, an annular groove is evenly opened on the lower surface of the half-sectioned cylinder, a parallel clamping plate is fixedly connected to the middle part of the inner wall of the half-sectioned cylinder, movable cover plates are symmetrically arranged on the front and rear sides of the inner wall of the parallel clamping plate, and a thrust spring belt is slidably connected to the middle part of the inner wall of the parallel clamping plate. Because the impact force of the ejected sandblasting solution is large, the reaction force received by the inner transfer tube is also large. The inner transfer tube is relatively large and is prone to shaking. After long-term use, the bottom end of the inner transfer tube is likely to loosen or detach from the upper part of the inner wall of the injection head. Therefore, a half-sectioned cylinder is required to provide a fixing surface, and the outer surface of the inner transfer tube is clamped on the outer surface of the half-sectioned cylinder through an annular groove. In order to ensure that the filling block and the inner wall of the movable sliding shell will not loosen and to facilitate the installation of the filling block, movable cover plates are arranged on both sides of the filling block. When installing the filling block, the movable cover plates on both sides are squeezed against each other, and the thrust spring belt is compressed and shortened. After the filling block is inserted into the bottom of the inner wall of the movable sliding shell, the movable cover plates on both sides are pushed to both sides under the elastic force of the thrust spring belt, so that the filling block is clamped on the inner wall of the movable sliding shell.

[0012] Preferably, the upper surface of the half-section cylinder and the lower part of the adapter plate are squeezed against each other, the number of the annular grooves is five, the upper part of the outer surface of the inner transfer tube is clamped with the lower surface of the half-section cylinder through the annular groove, the top end of the thrust spring belt is fixedly connected to the side of the movable cover plate close to the half-section cylinder, and the side of the outer surface of the movable cover plate close to the half-section cylinder is slidingly connected to the inner wall of the parallel clamping plate. When the inner transfer tube is subjected to a reaction force, the inner transfer tubes on both sides will squeeze the half-section cylinder, and the half-section cylinder will then prevent the movement of the inner transfer tube and provide a group of fixed surfaces to balance the impact force of the inner transfer tubes on both sides, so that the inner transfer tube is more stable, and the bottom end of the inner transfer tube and the upper part of the inner wall of the injection head are prevented from loosening or detaching, thereby increasing the service life of the device.

[0013] Preferably, the spray head includes a fixed housing, a slide groove is provided in the middle of the inner wall of the fixed housing, fixed teeth are evenly arranged on the lower part of the inner wall of the slide groove, the middle part of the inner wall of the fixed housing is slidably connected with a movable cylinder through the slide groove, and metal through tubes are symmetrically arranged on the left and right sides of the lower part of the inner wall of the movable cylinder. Because there are five groups of spray heads, before performing the spraying work, the operator needs to adjust the spray head and push the movable cylinder upward so that the outer surface of the movable cylinder disengages from the fixed teeth. At this time, the movable cylinder can be rotated to adjust the spraying angle of the metal through tube. After the adjustment, the movable cylinder is reinserted between the fixed teeth. Since the sandblasting solution passes through the movable cylinder from top to bottom during operation, the movable cylinder will not disengage from the fixed teeth during operation, thereby ensuring the fixity of the spraying angle of the metal through tube.

[0014] Preferably, the top end of the metal through tube extends to the interior of the movable cylinder, the upper part of the outer surface of the metal through tube is fixedly connected to the inner wall of the movable cylinder, the upper part of the outer surface of the movable cylinder is clamped with the lower part of the inner wall of the slide groove through fixed clamping teeth, the upper part of the inner wall of the fixed clamping shell is fixedly connected to the bottom of the outer surface of the inner transfer tube, and the middle part of the outer surface of the fixed clamping shell is fixedly connected to the lower part of the inner wall of the movable slide shell. The device has five groups of spray heads, which can fine-tune the spray angle of the metal through tube according to the shape of the steel bar and the rusted part, so that the sprayed sandblasting solution can more effectively flush the rust on the outer surface of the color steel, improve the rust removal efficiency and effect, and thus improve the work production efficiency.

[0015] The beneficial effects of the present invention are as follows: 1. The biggest advantage of this device is that it can replace manual rust removal work and remove rust from the outer surface of rusty long colored steel strips. Since the rotating motor and the torque motor are controllable, the stability of the device during rust removal movement can be guaranteed, so that the device can accurately remove rust from the outer surface of the colored steel, improving the efficiency of rust removal and the stability of rust removal effect.

[0016] 2. If rust is removed by high-pressure sandblasting solution, during the rust removal process, rust and sandblasting solution will diffuse into the surrounding air, causing environmental pollution and causing damage to the operator's body. Therefore, manual rust removal will wear protective clothing to perform rust removal work. The device can isolate the removed rust and the scattered sandblasting solution through relatively sealed vertical side plates, thereby greatly reducing environmental pollution.

[0017] 3. The device can adjust the width of the vertical side plate according to the different models and widths of color steel bars, ensuring that the device can completely cover the color steel bars, increasing the versatility of the device, and avoiding the problem that the color steel bars are too wide, the device cannot be used, and the practical performance of the device is poor.

[0018] 4. When the inner transfer tube is subjected to reaction force, the inner transfer tubes on both sides will squeeze the half-split cylinder, which in turn prevents the movement of the inner transfer tube and provides a set of fixed surfaces to balance the impact force of the inner transfer tubes on both sides, making the inner transfer tube more stable and preventing the bottom end of the inner transfer tube from loosening or detaching from the upper part of the inner wall of the injection head, thereby increasing the service life of the device.

[0019] 5. The device has five sets of spray heads, which can fine-tune the spray angle of the metal pipe according to the shape of the steel bar and the rusted parts, so that the sprayed sandblasting solution can more effectively wash away the rust on the outer surface of the color steel, improve the rust removal efficiency and effect, and thus improve work production efficiency.

Example

[0023] See also Figure 1-Figure 4 The present invention provides a technical solution: a rust removal device 6 for manufacturing color steel structure, including a splicing device 1, and external plates 2 are symmetrically arranged on the left and right sides of the outer surface of the splicing device 1.

[0024] The splicing device 1 includes a vertical side plate 11, and the upper part of the inner wall of the vertical side plate 11 is evenly provided with through-turns. The upper part of the inner wall of the vertical side plate 11 is rotatably connected with an adjustment rod 13 through the through-turn.

[0026] The rust removal device 6 includes a movable sliding shell 61, the upper surface of which is fixedly connected to an external clamping plate 65, and rotating screws 66 are evenly arranged on the front and rear sides of the upper surface of the external clamping plate 65. The upper part of the inner wall of the movable sliding shell 61 is slidably connected to a transport hollow plate 62, and the front and rear sides of the upper part of the inner wall of the movable sliding shell 61 are symmetrically arranged with adapter plates 64, and the outer surface of the adapter plate 64 is symmetrically arranged with folding partitions 63 on the left and right sides away from one end of the inner wall of the movable sliding shell 61, and the lower part of the inner wall of the movable sliding shell 61 is provided with an adjustment nozzle 7.

[0027] There are two folding partitions 63, and the upper and lower sides of the outer surface of the folding partition 63 are fixedly connected to the inner wall of the transport hollow plate 62. The outer surface of the adapter plate 64 extends to the interior of the transport hollow plate 62 away from one end of the inner wall of the movable sliding shell 61, and the inner wall of the external splint 65 is clamped with the lower part of the outer surface of the long transmission belt 12. The two ends of the transport hollow plate 62 extend to the interior of the large-capacity cylinders 51 on the left and right sides respectively.

[0028] The side of the outer surface of the large-capacity cylinder 51 away from the torque motor 53 is fixedly connected to one side of the outer surface of the vertical side plate 11, and the side of the convex push plate 55 is threadedly connected to the upper part of the inner wall of the large-capacity cylinder 51 through the threaded groove 52. The upper part of the inner wall of the large-capacity cylinder 51 is filled with rust removal liquid, and the bottom of the inner wall of the torque motor 53 is fixedly connected to an external wire.

[0029] Both ends of the adjustment rod 13 extend to the outside of the vertical side plate 11, and both sides of the outer surface of the adjustment rod 13 are rotatably connected to the inner wall of the vertical side plate 11. There are four external plates 2, and one end of the external plate 2 close to the splicing device 1 is fixedly connected to the outer surface of the vertical side plate 11, and the upper part of the inner wall of the short transmission belt 4 is rotatably connected to one end of the outer surface of the adjustment rod 13.

[0030] Before using the device to remove rust from color-coated steel, first rotate the convex push plate 55 of the large-capacity cylinder 51 to the lowest position, fill the upper surface of the convex push plate 55 with sandblasting solution, and then insert the color-coated steel into the interior of the splicing device 1. Pull the vertical side plates 11 on both sides according to the actual width of the color-coated steel, and adjust the pull rod 13 for telescopic adjustment to ensure that the color-coated steel is inside the splicing device 1 and does not contact the device inside the splicing device 1.

[0031] Start the rotating motors 3 on both sides and the torque motor 53 inside the pressurizing device 5. The rotating motor 3 controls the adjusting rods 13 on both sides to rotate through the short transmission belt 4. The adjusting rods 13 drive the long transmission belt 12 to rotate, thereby making the rust removal device 6 on the lower surface of the long transmission belt 12 move in the horizontal plane. When the torque motor 53 is working, the output shaft of the torque motor 53 controls the convex push plate 55 to spirally rise on the inner wall of the large-capacity cylinder 51 through the telescopic sleeve 54. The convex push plate 55 squeezes and transports the sandblasting solution to the inside of the movable sliding shell 61 through the transport hollow plate 62. At this time, the telescopic sleeve 54 is elongated to continue to maintain the connection between the torque motor 53 and the convex push plate 55.

[0032] The sandblasting solution discharged from the pressurizing device 5 enters the adapter plate 64 through the transport hollow plate 62, and is then sprayed onto the outer surface of the color steel directly below by adjusting the nozzle 7. During the movement of the rust removal device 6, the two sides of the outer surface of the adapter plate 64 push the folding partition 63, and the inner wall of the movable sliding shell 61 slides along the outer surface of the transport hollow plate 62. Due to the blocking effect of the folding partition 63, during the movement of the movable sliding shell 61, the sandblasting solution discharged from the pressurizing device 5 will not leak from the side of the transport hollow plate 62.

[0033] Because the rust removal device 6 is clamped on the lower surface of the long transmission belt 12 by the external clamping plate 65, the long transmission belt 12 can control the rust removal device 6 to reciprocate. In conjunction with the spraying action of the sandblasting solution under the action of pressure, the sandblasting solution sprayed by the rust removal device 6 can remove the rust on the outer surface of the color steel swept directly below.

[0043] The upper surface of the half-section cylinder 81 and the lower part of the adapter plate 64 are squeezed against each other, and the number of the annular grooves 82 is five. The upper part of the outer surface of the inner adapter tube 71 is clamped with the lower surface of the half-section cylinder 81 through the annular groove 82.

[0046] Because the impact force of the ejected sandblasting solution is large, the reaction force on the inner transfer tube 71 is also large, and the inner transfer tube 71 is prone to shaking. After long-term use, the bottom end of the inner transfer tube 71 may become loose or detached from the upper part of the inner wall of the injection head 9, so the half-section cylinder 81 is needed to provide a fixing surface, and the outer surface of the inner transfer tube 71 is clamped on the outer surface of the half-section cylinder 81 through the annular groove 82.

[0047] In order to ensure that the filling block 81 and the inner wall of the movable sliding shell 61 will not loosen and to facilitate the installation of the filling block 81, movable cover plates 85 are set on both sides of the filling block 81. When installing the filling block 81, the movable cover plates 85 on both sides are squeezed against each other, and the thrust spring belt 84 is compressed and shortened. After the filling block 81 is inserted into the bottom of the inner wall of the movable sliding shell 61, the movable cover plates 85 on both sides are pushed to both sides under the elastic force of the thrust spring belt 84, thereby making the filling block 81 clamped on the inner wall of the movable sliding shell 61.

[0048] Because there are five groups of spray heads 9, before performing the spraying work, the operator needs to adjust the spray head 9 and push the movable cylinder 93 upwards so that the outer surface of the movable cylinder 93 is disengaged from the fixed teeth 94. At this time, the movable cylinder 93 can be rotated to adjust the spraying angle of the metal through tube 95. After the adjustment, the movable cylinder 93 is reinserted between the fixed teeth 94. Since the sandblasting solution passes through the movable cylinder 93 from top to bottom during operation, the movable cylinder 93 will not be disengaged from the fixed teeth 94 during operation, thereby ensuring the fixity of the spraying angle of the metal through tube 95.
