Description

Technical Field

[0002] In modern construction and structural engineering, steel pipes are widely used in various occasions as one of the main building materials. Steel pipes include pipe bodies and chassis, and there are often impurities such as zinc slag on the chassis. These impurities not only affect the appearance of the steel pipes, but also affect the service life and safety of the steel pipes. However, existing steel pipe processing equipment cannot effectively remove impurities such as zinc slag on the chassis.

[0003] Existing conventional grinding equipment has many problems in removing zinc slag and other impurities. First, conventional grinding equipment has poor removal effect and cannot completely remove zinc slag and other impurities on the chassis, resulting in obvious traces of impurities still existing on the surface of the steel pipe. This not only affects the aesthetics of the steel pipe, but may also have an adverse effect on the subsequent coating process and even affect the anti-corrosion performance of the steel pipe. Secondly, conventional grinding equipment does not remove comprehensively, and it is difficult to perform all-round grinding of the circumference of the bottom plate during use, resulting in cleaning dead corners on the chassis. In addition, conventional grinding equipment is inefficient and takes a long time to complete the grinding of steel pipes, which increases construction costs and time, which not only increases the overall cost of construction and structural engineering, but also prolongs the construction period and affects the progress of the project. Finally, conventional grinding equipment is incompatible and cannot be applied to steel pipes of different specifications and sizes, which limits its scope of application.

[0031] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. Embodiment 1

[0032] See also Figure 1 and Figure 2As shown, this embodiment provides a steel pipe chassis finishing equipment, which includes: a positioning mechanism 100, the positioning mechanism 100 includes a push assembly 110 and at least one support assembly 120, the push assembly 110 includes a first top plate 111 and a second top plate 114 that move relatively along the length direction of the steel pipe, and the two ends of the steel pipe 500 to be processed are respectively abutted against the first top plate 111 and the second top plate 114, at least one support assembly 120 is arranged between the first top plate 111 and the second top plate 114, and moves up and down along the height direction of the positioning mechanism 100, and the steel pipe 500 to be processed is supported on at least one support assembly 120; at least one clamping rotation Mechanism 200, at least one of the clamping and rotating mechanisms 200 is arranged between the first top plate 111 and the second top plate 114, which clamps the tube body 510 of the steel tube 500 to be processed and drives the steel tube 500 to be processed to rotate around its axis; heating mechanism 300, the heating mechanism 300 includes a heating spray gun 320 and a temperature sensor 310, and the working ends of the heating spray gun 320 and the temperature sensor 310 are both arranged toward the bottom plate 520 of the steel tube 500 to be processed; grinding mechanism 400, the grinding mechanism 400 includes at least one grinding wheel 450, and at least one of the grinding wheels 450 moves close to / away from the bottom plate 520 of the steel tube 500 to be processed.

[0033] The steel pipe chassis finishing equipment described in this embodiment positions and supports the steel pipe 500 to be processed through the positioning mechanism 100, and then stably rotates and drives it through the clamping and rotating mechanism 200. During this process, the heating mechanism 300 heats the steel pipe chassis 520, thereby reducing the connection strength between impurities such as zinc slag and the chassis 520. Finally, the surface of the chassis 520 is fully polished by the grinding mechanism 400 until the impurities are completely separated from the surface of the chassis 520, completing the finishing process of the steel pipe chassis 520. In this application, the coordination and cooperation between the various mechanisms are high, and it can carry out comprehensive and thorough finishing treatment on the steel pipe chassis 520 in a targeted manner. Compared with the existing conventional grinding equipment, this application can drive the steel pipe to rotate as a whole, and in this process, it can cooperate with the heating treatment and grinding treatment respectively to reduce the processing dead angle, and has high positioning accuracy and clamping stability. In addition, this application also has significant advantages such as strong compatibility, high processing efficiency and good processing quality.

[0034] In this embodiment, the positioning mechanism 100 is used to position the steel pipe 500 to be processed so that it can be stably located at the processing site to facilitate the smooth progress of the subsequent processing process and improve the processing quality. In addition, the positioning mechanism 100 can also support the tube body 510 of the steel pipe 500 to be processed, thereby avoiding the problem of damage to the tube body 510 due to the tube body 510 being too long or too heavy; the clamping and rotating mechanism 200 can clamp the steel pipe 500 to be processed on the one hand to avoid lateral deviation during the processing. On the other hand, it also provides a rotational driving force for the steel pipe 500 to be processed, so that it can rotate around its axis, so as to reduce processing dead angles and simplify the equipment structure; the heating mechanism 300 is used to heat the chassis 520 of the steel pipe 500 to be processed. It is worth mentioning that the heating treatment can reduce the surface hardness of the steel pipe on the one hand, thereby quickly removing oxide scale and impurities in the subsequent grinding process and reducing the grinding time.

[0035] See also Figure 3 and Figure 4 As shown, the first top plate 111 and the second top plate 114 respectively abut against the two ends of the length direction of the processing tube body 510, wherein the first top plate 111 is connected to the working end of the first push driver 112, and can be horizontally moved toward the steel pipe through the first push driver 112. The push assembly 110 includes a first module 115, a first slide 116 and a second push driver 117. The first module 115 extends horizontally toward the first top plate 111, and the first slide 116 is slidably connected to the first top plate 111 through the second push driver 117. The first module 115 and the first slide 116 are provided with a lifting module 1161 on one side facing the first top plate 111, and one end of the lifting module 1161 is connected to the lifting driver 113. The second top plate 114 moves horizontally with the first slide 116 and moves along the lifting module 1161 through the lifting driver 113. Based on the above structure, the first top plate 111 and the second top plate 114 can move relative to each other, and the second top plate 114 can move in its height direction to improve its compatibility and flexibility of use.

[0036] See also Figures 3 to 5As shown, the support assembly 120 in this embodiment is arranged close to the first top plate 111 to support the tube body 510 of the steel tube 500 to be processed. In the actual processing process, the length and mass of the steel tube 500 to be processed are usually large, so the arrangement of the support assembly 120 can reduce the collapse tendency of the tube body 510, thereby improving the protection effect of the tube body 510. Further, the support assembly 120 includes a support frame 121, a first transmission assembly 122 and at least two support arms 123, the support frame 121 is arranged below the steel tube 500 to be processed, the first transmission assembly 122 is arranged on the support frame 121, the support arm 123 is lifted and moved by the first transmission assembly 122, and the steel tube 500 to be processed is located between at least two of the support arms 123. This embodiment includes two support arms 123, which are symmetrically arranged along the width direction of the tube body 510 and extend along the height direction of the positioning mechanism 100. Therefore, they can not only support the tube body 510, but also limit the width direction of the tube body 510 during its rotation, thereby maximizing the stability of the steel tube during rotation.

[0037] Further, see Figure 5 and Figure 6 As shown, the first transmission assembly 122 includes a first rotary driver 1221, a first driving wheel 1222, a first driven wheel 1224, a first transmission belt 1223, a gear 1226, a connecting rod 1225, a lifting plate 1228 and a rack 1227. The rotary driver is arranged on one side of the support frame 121, the first driving wheel 1222 is connected to the working end of the rotary driver, the first driven wheel 1224 is rotatably connected to the support frame 121, and the first transmission belt 1223 is sleeved on the first driving wheel 1222. On the driving wheel 1222 and the first driven wheel 1224, the connecting rod 1225 passes through the first driven wheel 1224, the gear 1226 is sleeved on the middle of the connecting rod 1225, the gear 1226 and the connecting rod 1225 rotate synchronously with the first driven wheel 1224, one side of the lifting plate 1228 is connected to at least two of the support arms 123, and the other side is connected to the rack 1227, the rack 1227 extends along the height direction of the support assembly 120, and meshes with the gear 1226. Based on the above structure, the present application can convert the rotational driving force into a linear driving force applied synchronously to the two support arms 123, which can not only reduce the volume and production cost of the support assembly 120, but also make the two support arms 123 evenly stressed to improve the support stability.

[0038] See also Figures 7 to 9As shown, the clamping and rotating mechanism 200 includes two opening and closing plates 230, which are respectively arranged on both sides of the steel pipe 500 to be processed and move relatively close to / away from each other.

At least two rotating wheels 231 are arranged around the avoidance groove, and any of the rotating wheels 231 rotates around its central axis. In this embodiment, the steel pipe is clamped by two horizontally moving opening and closing plates 230, wherein any of the opening and closing plates 230 is provided with two rotating wheels 231, and the four rotating wheels 231 can stably squeeze and clamp the pipe body 510. Furthermore, the clamping and rotating mechanism 200 in this embodiment includes a clamping frame 270, a movable plate 220, a third pushing driver 210, a guide module 240 and a reset member 250. The guide module 240 extends along the width direction of the clamping and rotating mechanism 200 and is arranged on the clamping frame 270. The two opening and closing plates 230 are respectively slidably connected to the guide module 240. The reset member 250 is arranged between the two opening and closing plates 230. A guide portion 232 is provided at the bottom of any opening and closing plate 230. The guide portion 232 is gradually inclined upward from the center of the guide module 240 to both ends. The movable plate 220 is connected to the working end of the third pushing driver 210 and is provided with two extrusion wheels 221. The two extrusion wheels 221 are respectively abutted against the two guide inclined surfaces and move along the guide inclined surfaces to drive the corresponding opening and closing plates 230 to move. Therefore, the two opening and closing plates 230 can be driven synchronously through the third pushing drive 210. Furthermore, any opening and closing plate 230 can be raised and lowered in the height direction and also have a horizontal displacement effect. This can improve the clamping effect on the tube body 510 and make the surface of the tube body 510 evenly stressed. On the other hand, it also simplifies the production complexity and processing cost.

[0043] This embodiment provides a method for finishing a steel tube chassis, which uses the steel tube chassis finishing equipment described in the first embodiment to finish the chassis 520 of the steel tube, and includes:

[0044] Step S1, fix the two ends of the steel pipe to be processed in the length direction to position it in the length direction. In this embodiment, the steel pipe to be processed is fixed so that its two ends are respectively in contact with the first top plate 111 and the second top plate 114 to achieve positioning in the length direction of the steel pipe; specifically, step S1 is specifically: after adjusting the first top plate 111 and the second top plate 114 to the same horizontal height, the first top plate 111 and the second top plate 114 are moved relatively close to each other until the steel pipe 500 to be processed is clamped between the two to achieve positioning in the length direction of the steel pipe.

[0045] Step S2, supporting the tube body of the steel tube to be processed and limiting it in the width direction. In this embodiment, at least one supporting assembly 120 is raised until it contacts and supports the tube body 510 of the steel tube 500 to be processed; step S2 is specifically: driving the two supporting arms 123 to rise synchronously through the first transmission assembly 122 until they abut against the tube body 510 of the steel tube 500 to be processed and then stop, at which time the tube body 510 of the steel tube 500 to be processed is located between the two supporting arms 123.

[0046] Step S3, drive the steel pipe to be processed to rotate around its axis, and heat the chassis of the steel pipe to be processed until the chassis reaches the target temperature; in this embodiment, at least one clamping and rotating mechanism 200 clamps the tube body 510 of the steel pipe 500 to be processed, and the clamping and rotating mechanism 200 clamps or releases the tube body 510 through the relative opening and closing movement of the two opening and closing plates 230. Based on the squeezing effect between the rotating wheel 231 and the tube body 510, a large friction can be generated between the two, thereby facilitating the rotating wheel 231 to drive the steel pipe 500 to be processed to rotate around its axial direction. Further, in this embodiment, the rotating wheel 231 is driven by the second transmission assembly 260, thereby indirectly driving the steel pipe to rotate. In this embodiment, step S3 is specifically as follows: the bottom plate 520 of the steel pipe 500 to be processed is heated by the heating spray gun 320, and the steel pipe 500 to be processed is rotated around its axis by at least one clamping rotating mechanism 200, and the heating is stopped after a preset time, and the surface temperature of the bottom plate 520 is detected by the temperature sensor 310.

[0047] When the bottom plate 520 reaches the target temperature, the next step is directly performed;

[0048] When the bottom plate 520 does not reach the target temperature, the above heating process is repeated, and the surface temperature of the bottom plate 520 is re-detected until the bottom plate 520 reaches the target temperature and then the next step is performed.

[0049] Step S4, maintain the rotation state of the steel pipe 500 to be processed, and grind the chassis 520 through the grinding mechanism 400 to complete the steel pipe chassis finishing process. During this process, the operator can adjust the position, angle, speed, etc. of the grinding wheel 450 in real time or preset parameters to achieve the optimal finishing effect.

[0050] In summary, the steel pipe chassis finishing equipment and method described in the present invention positions and supports the steel pipe 500 to be processed through the positioning mechanism 100, and then stably rotates and drives it through the clamping and rotating mechanism 200. During this process, the heating mechanism 300 heats the steel pipe chassis 520, thereby reducing the connection strength between impurities such as zinc slag and the chassis 520. Finally, the surface of the chassis 520 is fully polished by the grinding mechanism 400 until the impurities are completely separated from the surface of the chassis 520, completing the finishing process of the steel pipe chassis 520. The coordination and cooperation between the various mechanisms in this application is high, and it can carry out comprehensive and thorough finishing treatment on the steel pipe chassis 520 in a targeted manner. Compared with the existing conventional grinding equipment, this application can drive the steel pipe to rotate as a whole, and in this process, it can cooperate with the heating treatment and grinding treatment respectively to reduce the processing dead angle, and has high positioning accuracy and clamping stability. In addition, this application also has significant advantages such as strong compatibility, high processing efficiency and good processing quality.
