Description

Technical Field

[0001] The present invention relates to the technical field of shipbuilding, and more particularly to a T-shaped steel rust removal device and rust removal process for shipbuilding. Background Art

[0002] During the shipbuilding process, T-shaped steel is required. However, before use, the T-shaped steel is stored in a warehouse, and during storage, the surface of the T-shaped steel is prone to moisture and rust. When using T-shaped steel to build a ship, it is necessary to first perform rust removal on the outer surface of the T-shaped steel. The current rust removal method is to immerse the T-shaped steel in the rust removal liquid, and then use an ultrasonic generator to generate ultrasonic waves. The ultrasonic waves shake off the loose rust through high-frequency vibration, thereby achieving the rust removal effect. However, the current rust removal device has the following disadvantages: The support part of the T-shaped steel is fixed and cannot be adjusted, resulting in the ultrasonic waves and the rust removal liquid being unable to contact the support part of the T-shaped steel, so that the rust on the support part of the T-shaped steel cannot be completely removed, and it is necessary to perform additional rust removal operations on the support part of the T-shaped steel separately. The operation is cumbersome, the operation efficiency is low, and the rust removal operation takes a long time.

[0003] Chinese Patent CN112376063B discloses a rust removal device for T-shaped steel used in shipbuilding, including: a rust removal tank, a power mechanism, a support mechanism, and a grasping mechanism. The rust removal tank is used to hold the rust removal liquid. The power mechanism is arranged between the inner bottom surface and the side wall of the rust removal tank. The support mechanism is movably arranged on the power mechanism and can support the T-shaped steel. The grasping mechanism is arranged on the outer side wall of the rust removal tank and can grasp the T-shaped steel to put the T-shaped steel into the rust removal tank or take the T-shaped steel out of the rust removal tank. At least four support mechanisms are provided, and the four support mechanisms are respectively distributed at both ends of the bottom surface of the T-shaped steel. The support mechanism includes a moving block, a first telescopic member, an auxiliary roller, a diagonal support rod, a supporting roller, and a winding mechanism. The moving block can move along the height direction of the rust removal tank. The first telescopic member is fixedly arranged at the inner bottom end of the moving block. The auxiliary roller is rotatably arranged at the inner end of the first telescopic member and is used to assist in supporting the web of the T-shaped steel. The diagonal support rod is rotatably arranged at the inner top end of the moving block. The supporting roller is rotatably arranged at the inner end of the diagonal support rod and is used to support the bottom surface of the top plate of the T-shaped steel. The winding mechanism is arranged at the top of the moving block and can drive the diagonal support rod to swing around the moving block. An ultrasonic generator is arranged on the inner wall of the rust removal tank, and the ultrasonic generator is immersed in the rust removal liquid inside the rust removal tank.

[0004] Although the above solution does not require rust removal of the support components of the T-shaped steel, due to the structural characteristics of the T-shaped steel, the existing rust removal devices cannot completely clean the corners of the T-shaped steel. As a result, the rust at the corners of the T-shaped steel will become more and more serious, which may lead to the fracture of the T-shaped steel. Moreover, the devices specifically for cleaning the corners are too inefficient and not conducive to production use. At the same time, the existing devices for cleaning the side walls of the T-shaped steel require multiple sets of drivers, which not only increases the cost but also the workload of later maintenance. Summary of the Invention

[0005] In view of the above problems, a rust removal device and a rust removal process for T-shaped steel in shipbuilding are provided. The conveying device drives the T-shaped steel to move along the length direction of the outer shell. The driving device first drives the push rod to approach the T-shaped steel, and the sides of the two rotating sleeves close to the T-shaped steel gradually separate. The first gear drives the cleaning member arranged on the rotating sleeve to rotate through the transmission component, and the cleaning member cleans the rust at the turning points of the T-shaped steel. Then the driving device drives the push rod to move away from the T-shaped steel, and the elastic component pulls the rotating sleeve back to its original position.

[0041] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Referring to Figure 1 、 Figure 6 、 Figure 9 and Figure 10 : A T-shaped steel rust removal device for shipbuilding, including a housing 1 for receiving the T-shaped steel, a cleaning device 2 and a conveying device; the cleaning device 2 includes a cleaning member 21, a rotating sleeve 22, a first gear 221, a transmission assembly 23, an elastic assembly 24, a push rod 25 and a driving device 26; a cleaning liquid is provided in the housing 1, the rotating sleeve 22 is provided in the housing 1, there are four rotating sleeves 22, every two rotating sleeves 22 form a group, and one ends of the two rotating sleeves 22 in each group are close to each other; there are two first gears 221, and the two first gears 221 are respectively fixedly arranged on the side walls of the two rotating sleeves 22 at the ends close to each other, and the two first gears 221 are meshed with each other; the cleaning member 21 is rotatably arranged at the end of the rotating sleeve 22 away from the first gear 221, and the cleaning member 21 contacts the side wall of the T-shaped steel; the transmission assembly 23 is arranged in the rotating sleeve 22, and the first gear 221 drives the cleaning member 21 to rotate through the transmission assembly 23; the push rod 25 is arranged on the side of the rotating sleeve 22 close to the housing 1, the push rod 25 penetrates through the side wall of the housing 1, and one ends of the two rotating sleeves 22 close to each other are hinged to the end of the push rod 25, and the push rod 25 can horizontally move along the width direction of the housing 1; the elastic assembly 24 is arranged inside the push rod 25, and the elastic assembly 24 can drive the two rotating shells to rotate and approach each other; the driving device 26 is arranged on the upper part of the push rod 25, and the driving device 26 drives the push rod 25 to reciprocate along the width direction of the housing 1.

[0043] Place the T-shaped steel on the conveying device. The conveying device drives the T-shaped steel, causing the T-shaped steel to move along the length direction of the outer shell 1. Two sets of rotating sleeves 22 are respectively arranged on both sides of the T-shaped steel. The cleaning member 21 is always in contact with the side wall of the T-shaped steel. When the device is started, the driving device 26 will be started synchronously. The driving device 26 drives the push rod 25 to reciprocate along the width direction of the outer shell 1. The push rod 25 slides relative to the side wall of the outer shell 1. Under the push of the push rod 25, the rotating sleeve 22 hinged to one end of the push rod 25 will rotate. The two rotating sleeves 22 arranged at one end of the push rod 25 gradually separate. In this way, the cleaning member 21 arranged on the rotating sleeve 22 will move along the height direction of the outer shell 1. This is because the cleaning member 21 is always in contact with the side wall of the T-shaped steel, and the T-shaped steel only moves along the length direction of the outer shell 1. In this way, it is ensured that the cleaning member 21 can only move along the height direction of the outer shell 1. After the two rotating sleeves 22 separate, the cleaning member 21 on the upper rotating sleeve 22 will contact the turning point of the T-shaped steel. Since the rotating sleeve 22 is in a state of continuously opening and closing under the push of the push rod 25, in this way, under the transmission of the transmission component 23, the cleaning member 21 is always in a rotating state, so that the cleaning member 21 can clean the turning point of the T-shaped steel and the entire side wall of the T-shaped steel. When the push rod 25 drives the rotating sleeve 22 away from the T-shaped steel, the elastic component 24 in the push rod 25 generates a pulling force on the rotating sleeve 22, so that the cleaning member 21 on the rotating sleeve 22 is always in contact with the side wall of the T-shaped steel, so that the device can clean the turning point of the T-shaped steel more cleanly, and at the same time can reduce the maintenance cost and maintenance workload.

[0044] Refer to Figure 6 、 Figure 9 and Figure 10 : The transmission component 23 includes a second gear 231, a third gear 232, a fourth gear 233 and a belt drive component 234; The second gear 231 is arranged on one side of the first gear 221, and the second gear 231 meshes with the first gear 221; The third gear 232 is fixedly arranged on one side of the second gear 231 along the axis of the second gear 231, and the diameter of the third gear 232 is larger than that of the second gear 231; The fourth gear 233 is arranged on one side of the third gear 232 close to the rotating sleeve 22, and the fourth gear 233 meshes with the third gear 232; The belt drive component 234 is arranged on one side of the fourth gear 233, and the fourth gear 233 drives the cleaning member 21 to rotate through the belt drive component 234.

[0045] When the push rod 25 pushes the rotating sleeve 22, the cleaning member 21 provided on the rotating sleeve 22 will extrude the T-shaped steel, and at the same time, the two rotating sleeves 22 will gradually separate. In this way, the first gears 221 provided at one end of the two rotating sleeves 22 will rotate relatively. Since the first gear 221 and the second gear 231 are meshed with each other, the second gear 231 will be driven to rotate by the first gear 221. Since the second gear 231 is fixedly connected to the third gear 232, the angular velocity of the rotation of the third gear 232 is always the same as that of the second gear 231. In this way, the third gear 232 will also rotate synchronously with the second gear 231. The third gear 232 is meshed with the fourth gear 233, so the fourth gear 233 will also rotate. The fourth gear 233 drives the cleaning member 21 to rotate through the belt drive assembly 234. In this way, the use of the driver is reduced, and the later maintenance cost is reduced.

[0046] Refer to Figure 7 and Figure 9 : The belt drive assembly 234 includes a synchronous pulley 2341 and a synchronous belt 2342; there are two synchronous pulleys 2341, and the two synchronous pulleys 2341 are arranged along the length direction of the rotating sleeve 22. One of the synchronous pulleys 2341 is fixedly provided on one side of the fourth gear 233, and the other synchronous pulley 2341 is fixedly provided on one side of the cleaning member 21; both ends of the synchronous belt 2342 are sleeved on the two synchronous pulleys 2341 respectively, and the synchronous pulley 2341 is in transmission cooperation with the synchronous belt 2342.

[0047] After the fourth gear 233 rotates, since one of the synchronous pulleys 2341 is fixedly connected to the fourth gear 233, the synchronous pulley 2341 provided on one side of the fourth gear 233 will rotate synchronously, and the synchronous belt 2342 is in transmission cooperation with the synchronous pulley 2341, so that the synchronous pulley 2341 will rotate synchronously. Since the other synchronous pulley 2341 is fixedly connected to the cleaning member 21, the cleaning member 21 can be driven to rotate.

[0048] Refer to Figure 6 and Figure 8 : The elastic component 24 includes a wire reel 241, a sliding block 242, a first spring 243 and a towing rope 244; the wire reel 241 is provided on the side wall of the first gear 221;

[0049] A chute is opened at one end of the push block close to the rotating sleeve 22, and the sliding block 242 is slidably arranged in the chute; the towing rope 244 is wound in the wire reel 241, and one end of the towing rope 244 away from the wire reel 241 is fixedly connected to the push block. The first gear 221 can drive the wire reel 241 to retract the towing rope 244; there is a first gap between the sliding block 242 and the bottom of the chute, and the first spring 243 is arranged in the first gap.

[0050] When the first gear 221 rotates, the first gear 221 drives the winding box to wind the towing rope 244. The towing rope 244 pulls the sliding block 242 to slide in the chute. Since there is a first gap between the sliding block 242 and the bottom of the chute, when the sliding block 242 is pulled by the towing rope 244, the first gap between the sliding block 242 and the bottom of the chute gradually becomes larger. Both ends of the first spring 243 arranged in the first gap are fixedly connected to the sliding block 242 and the bottom of the chute respectively. In this way, after the sliding block 242 is driven by the towing rope 244 to slide, the first spring 243 is gradually stretched. When the pushing block drives the rotating sleeve 22 to move away, the reaction force of the first spring 243 will pull the sliding block 242, so that the towing rope 244 wound in the winding box is stretched out. In this way, it will drive the first gear 221 arranged on one side of the winding box to rotate. Under the meshing action of the two first gears 221, the rotating sleeves 22 will approach each other.

[0051] Refer to Figures 1 - 3 : The driving device 26 includes a disc 261, a first connecting rod 262, a connecting frame 263, an extension rod 2631, a rotating wheel 264, a driving belt 265 and a rotary driver; the rotating wheel 264 is rotatably arranged on the upper part of the housing 1, and the axis of the rotating wheel 264 is parallel to the height direction of the housing 1; the driving belt 265 is arranged on one side of the rotating wheel 264, and the driving belt 265 is in transmission cooperation with the rotating wheel 264; the rotary driver is arranged at one end of the driving belt 265, and the rotary driver can drive the driving belt 265 to rotate; there are two discs 261, and the two discs 261 are respectively fixedly arranged on the upper and lower sides of the rotating wheel 264 along the axis of the rotating wheel 264; the connecting frame 263 is fixedly arranged at the end of the pushing rod 25 away from the rotating sleeve 22; the extension rod 2631 is fixedly arranged on the end of the connecting frame 263 away from the rotating sleeve 22 along the width direction of the housing 1; a hinge column is fixedly arranged on the side of the disc 261 away from the rotating wheel 264, and the hinge column is located at a position away from the center of the disc 261; both ends of the first connecting rod 262 are respectively hinged to the hinge column and the end of the extension rod 2631 away from the connecting frame 263.

[0052] When driving the pushing rod 25 to move, the rotary driver is first started. The rotary driver drives the driving belt 265 to rotate, and the driving belt 265 drives the rotating wheel 264 to rotate. Since the rotating wheel 264 is fixedly connected to the disc 261, the disc 261 will be driven by the rotating wheel 264 to rotate. Since a hinge column is arranged on the upper part of the disc 261 and the hinge column is located at a position away from the center of the disc 261, when the disc 261 rotates, the hinge column rotates around the axis of the disc 261 and drives the first connecting rod 262 to drive the extension rod 2631 to move along the width direction of the housing 1, so that the extension rod 2631 drives the pushing rod 25 to move horizontally through the connecting frame 263.

[0053] Refer to Figure 1And Figure 3 : The driving device 26 further includes a stabilizing base 266; the stabilizing bases 266 are arranged uniformly along the length direction of the extension rod 2631, and the extension rod 2631 is in sliding fit with the stabilizing base 266.

[0054] The position of the stabilizing base 266 never changes. When the extension rod 2631 moves, the extension rod 2631 and the stabilizing base 266 slide relative to each other. Since the stabilizing bases 266 are arranged along the width direction of the housing 1, the moving direction of the extension rod 2631 must be the same as the width direction of the housing 1.

[0055] Refer to Figure 3 : The driving device 26 further includes a pressing assembly 267. The pressing assembly 267 includes a second spring 2671, a pressing seat 2672, and a pressing wheel 2673; the pressing wheel 2673 is arranged on the side of the driving belt 265 away from the rotating wheel 264; the pressing seat 2672 is arranged on the side of the pressing wheel 2673 away from the pressing wheel 2673; the second spring 2671 is arranged on the side of the pressing seat 2672 away from the pressing wheel 2673, and the second spring 2671 is in a compressed state.

[0056] Since the second spring 2671 is always in a compressed state, the reaction force of the second spring 2671 acts on the pressing wheel 2673 through the pressing seat 2672. The pressing wheel 2673 and the rotating wheel 264 squeeze the driving belt 265, ensuring that when the driving belt 265 rotates, the driving belt 265 can be in close contact with the rotating wheel 264, ensuring the stability of the transmission and preventing the driving belt 265 from slipping when driving the rotating wheel 264 to rotate.

[0057] Refer to Figure 2 : The pressing assembly 267 further includes a guide rail; the guide rail is arranged on one side of the pressing seat 2672 along the width direction of the housing 1, and the guide rail is used to guide the pressing seat 2672 to move along the width direction of the housing 1.

[0058] Under the guidance of the guide rail, the pressing seat 2672 can move stably along the width direction of the housing 1.

[0059] Refer to Figure 6 And Figure 8 : The elastic component 24 further includes a guide rod 245; the guide rod 245 is fixedly arranged in the chute along the extending direction of the chute. The guide rod 245 penetrates through the sliding block 242, and the guide rod 245 is in sliding fit with the sliding block 242.

[0060] By arranging the guide rod 245, the sliding block 242 can slide more stably along the length direction of the chute, avoiding the influence on the rotation of the first gear 221 when the cleaning liquid flows in the housing 1, and further making the extension length of the traction rope 244 in the take-up box 241 uneven.

[0061] Reference Figures 1 - 10 : The present invention also includes a rust removal process for T-shaped steel in shipbuilding, and the specific steps are as follows:

[0062] S1. The conveying device drives the T-shaped steel to move along the length direction of the outer shell 1, and the driving device 26 first drives the push rod 25 to approach the T-shaped steel;

[0063] S2. The sides of the two rotating sleeves 22 close to the T-shaped steel gradually separate, and the first gear 221 drives the cleaning member 21 provided on the rotating sleeve 22 to rotate through the transmission assembly 23, and the cleaning member 21 cleans the rust at the turning points on the T-shaped steel;

[0064] S3. The driving device 26 drives the push rod 25 away from the T-shaped steel, and the elastic assembly 24 pulls the rotating sleeve 22 back to its original position.

[0065] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the appended claims.
