Description

Technical Field

[0001] The invention relates to the technical field of galvanized steel pipe cleaning, and in particular to a multi-angle cleaning device for galvanized steel pipe production. Background Art

[0002] In the production process of galvanized steel pipes, cleaning is a crucial link. The main purpose of cleaning is to remove impurities such as oil, rust and oxide scale on the surface of the steel pipe to ensure the adhesion and quality of the galvanized layer. The cleaning effect directly affects the quality of the finished product and the service life of the galvanized steel pipe.

[0003] In the field of galvanized steel pipe cleaning, traditional cleaning methods often use a single cleaning angle, such as horizontal cleaning or vertical cleaning. Although this method can remove some impurities on the surface of the steel pipe, it is difficult to achieve a comprehensive and thorough cleaning effect, especially for the depressions, gaps and other hard-to-reach areas on the surface of the steel pipe. At the same time, stubborn impurities are difficult to remove by simply using water flow for cleaning. Therefore, traditional cleaning methods often cannot clean thoroughly, which will affect the quality of galvanizing. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0007] In the cleaning equipment, the device is used to clean the circular steel pipe in order to remove stains on its surface and inside. The main body mechanism provides a place for cleaning, the detection device is used to detect the circular grooves on the surface of the circular steel pipe, the cleaning mechanism is used to clean the circular steel pipe, and the steel pipe clamping mechanism is used to clamp the circular steel pipe to lift it for easy cleaning. At the same time, the steel pipe clamping mechanism can rotate the circular steel pipe so that the circular steel pipe can be more comprehensively detected and cleaned.

[0008] Furthermore, the main body mechanism includes a bottom plate, an upper cover, a fixed card block and a flat baffle, the bottom plate and the upper cover are fastened together, a drain groove is provided under the bottom plate, there are no less than two fixed cards, the fixed card block and the bottom plate are fastened together, the top of the fixed card block is a semicircular arc, one fixed card block is hollow in design, two flat baffles are provided, the two flat baffles are fastened together with the two ends of the semicircular arc above the fixed card block respectively, the two flat baffles are tilted downward, the bottom plate is connected to the detection mechanism, the bottom plate is connected to the cleaning mechanism, the bottom plate is connected to the steel pipe clamping mechanism, and the fixed card block is connected to the steel pipe clamping mechanism.

[0009] In the main mechanism, the main mechanism provides a cleaning place for the circular steel pipe. The bottom plate is used to support the entire cleaning device. A drainage trough is provided on the bottom plate. When the circular steel pipe is cleaned, the sewage after cleaning can be collected. The water can be filtered and other operations can be performed later to make the water clean for reuse. The fixed block is used to lift the circular steel pipe and support the circular steel pipe to facilitate the cleaning operation on the surface of the circular steel pipe. The flat baffle is tilted on both sides of the semicircular arc of the fixed block to facilitate the cleaning operation of the circular steel pipe. Most of the water can flow to both sides along the flat baffle when the circular steel pipe is cleaned, thereby reducing the interference of the motor and other components due to the water flow.

[0010] Furthermore, the detection mechanism includes an electric needle, a fixed plate and a mobile detection device. Two electric needles are provided. The two electric needles are fastened to the fixed plate, and the two electric needles are connected to a voltmeter through a wire. The fixed plate is connected to the mobile detection device, and the mobile detection device is fastened to the base plate.

[0011] In the detection mechanism, the mechanism is used to detect the depressions and protrusions on the circular steel pipe, and transmit the signal to the cleaning mechanism to adjust the angle. The fixed plate is fixedly connected to the two electric needles. When the electric needles are energized, the screw nut pair is driven by the servo motor to move the push plate along the screw nut pair. Since the front end of the push plate is tightly connected to the fixed plate, when the screw nut pair drives the push plate to move, the fixed plate will also move with the electric needles. After power is turned on, the two electric needles mark adjacent points on the surface of the circular steel pipe. When a protrusion or depression is detected, the potential difference between the surface of the circular steel pipe and the electric needle will change compared to when no detection is performed, and it will be displayed by a voltmeter to determine whether there are defects on the surface of the circular steel pipe, and then the cleaning mechanism will clean it.

[0012] Furthermore, the cleaning mechanism includes a water storage tank, a sand storage box, a main water pipe, a main sand pipe, a first regulating valve and a second regulating valve. The water storage tank is tightly connected to the bottom plate, the sand storage box is tightly connected to the bottom plate, the water storage tank is tightly connected to the main water pipe, the first regulating valve is tightly connected to the main water pipe, the sand storage box is tightly connected to the main sand pipe, and the second regulating valve is tightly connected to the main sand pipe.

[0013] In the cleaning mechanism, the inside and outside of the circular steel pipe are doubly cleaned by water flow and sand. The water tank and the sand storage box are used to provide cleaning raw materials, which are then output through the main water pipe and the main sand pipe respectively. The first regulating valve and the second regulating valve are used to control the opening and closing of the main water pipe and the main sand pipe.

[0014] Further, the cleaning mechanism also includes an internal cleaning device, which is connected to the fixed rod, the internal cleaning device is connected to the main water pipe, the internal cleaning device is connected to the main sand pipe, the internal cleaning device includes an internal water pipe, an internal sand pipe, an internal main pipeline, an internal nozzle, a first hydraulic cylinder, a mounting plate and a second hydraulic cylinder, one end of the internal water pipe is tightly connected to the main water pipe, one end of the internal water pipe away from the main water pipe is tightly connected to the internal main pipeline, one end of the internal sand pipe is tightly connected to the main sand pipe, one end of the internal sand pipe away from the main sand pipe is tightly connected to the internal main pipeline, the internal main pipeline is away from the internal sand pipe, one end of the internal water pipe is tightly connected to the internal nozzle, a circular through hole is provided on the mounting plate, the internal main pipeline passes through the circular through hole of the mounting plate, one end of the first hydraulic cylinder is tightly connected to the mounting plate, and the other end of the first hydraulic cylinder is tightly connected to the internal main pipeline The cleaning mechanism also includes an external cleaning device, which is connected to a push plate, a main water pipe, and a main sand pipe. The external cleaning device includes an external water pipe, an external sand pipe, an external main pipe, an external nozzle and a third hydraulic cylinder. One end of the external water pipe is connected to the main water pipe, an end of the external water pipe away from the main water pipe is connected to the external main pipe, one end of the external sand pipe is connected to the main sand pipe, an end of the external sand pipe is connected to the main sand pipe, an end of the external sand pipe is connected to the main sand pipe, an end of the external sand pipe is connected to the external main pipe, the external nozzle is connected to the external main pipe, one end of the third hydraulic cylinder is connected to the push plate, and the other end of the third hydraulic cylinder is connected to the external main pipe near the external nozzle.

[0015] In the cleaning mechanism, it is necessary to clean the inner and outer walls of the circular steel pipe, which is achieved through the internal cleaning device and the external cleaning device. The cleaning of the inner and outer walls can be carried out at the same time. First, the second regulating valve is closed to close the main sand delivery pipe, and the first regulating valve is opened to open the main water delivery pipe. The water flow in the main water delivery pipe is divided into two streams through the internal water delivery pipe and the external water delivery pipe, and then enters the inner main pipe and the outer main pipe respectively, and is sprayed out by the inner nozzle and the outer nozzle respectively. At the same time, the pushing speed of the second hydraulic cylinder and the screw nut pair is kept consistent during operation, and the inner nozzle and the outer nozzle are on the same vertical line. Since the external cleaning device is fixedly installed on the push plate, its position is behind the two electric needles, so the signal detected by the electric needle can be converted into the angle conversion of the inner nozzle and the outer nozzle in real time. In the initial state, the inner nozzle keeps spraying to the upper left through the first hydraulic cylinder. The outer nozzle maintains the spraying angle to the lower left through the third hydraulic cylinder. In the initial position, the cleaning mechanism is located on the right side of the circular steel pipe. During operation, it is moved to the left by the second hydraulic cylinder and the screw nut pair to detect the circular steel pipe. For detected protrusions or depressions, after the outer nozzle passes the highest point, the third hydraulic cylinder drives the outer nozzle to change its spraying angle from spraying to the lower left to spraying to the lower right, while the inner nozzle is driven by the first hydraulic cylinder to change its spraying angle from upper left to upper right, so that the angles formed by protrusions or depressions can be better cleaned. After cleaning, the water inside flows out along the circular steel pipe, and the water on the outer wall flows out along the flat baffles on both sides. After the water cleaning is completed, the first regulating valve is closed and the second regulating valve is opened. The operation of sandblasting cleaning is the same as that of water spraying cleaning.

[0016] Furthermore, the steel pipe clamping mechanism includes a ring pressing gear, a driving gear chain, a rotating shaft and a driving motor. Two rotating shafts are provided, and the two rotating shafts are respectively rotatably connected to the inner wall of a hollow fixed block. The two rotating shafts and the centers of the semicircular arcs of the fixed block are on the same vertical line. The driving gear chain is rotatably connected to the rotating shaft, the driving motor is tightly connected to the base plate, the output end of the driving motor is tightly connected to a rotating shaft, the ring pressing gear is rotatably connected to the fixed block, the ring pressing gear is meshed with the driving gear chain, and the ring pressing gear is placed at the semicircular arc of the fixed block.

[0017] In the steel pipe clamping mechanism, this mechanism is used to clamp and rotate the round steel pipe. The round steel pipe is inserted into the ring pressing gear. After the upper half of the round steel pipe is cleaned, the driving motor drives the rotating shaft to rotate, and the rotating shaft rotates with the driving gear chain. The ring pressing gear and the driving gear chain are meshed, so the driving gear chain will rotate with the round steel pipe. After rotating 180°, the detection mechanism and the cleaning mechanism work again.

[0018] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: after starting, the present invention places the circular steel pipe on the fixed clamping block, and the lead screw nut pair and the second hydraulic cylinder drive the detection mechanism, the external cleaning device and the internal cleaning device to move. After power is turned on, the two electric needles mark adjacent points on the surface of the circular steel pipe. When a bulge or depression is detected, the potential difference between the surface of the circular steel pipe and the electric needle will change compared to when no bulge or depression is detected, which is displayed by a voltmeter. By converting the signal detected by the electric needle into a change in the angle of the inner nozzle and the outer nozzle, in the initial state, the inner nozzle maintains an angle of spraying to the upper left through the first hydraulic cylinder, and the outer nozzle maintains an angle of spraying to the lower left through the third hydraulic cylinder. When a bulge or depression is detected, after the outer nozzle passes the highest point, the third hydraulic cylinder drives the outer nozzle to change its spray angle from spraying toward the lower left to spraying toward the lower right, while the inner nozzle, driven by the first hydraulic cylinder, changes its spray angle from the upper left to the upper right. This can better clean the angles formed by the bulge or depression. After cleaning, the water inside flows out along the circular steel pipe, and the water on the outer wall flows out along the flat baffles on both sides. After the water cleaning is completed, the first regulating valve is closed and the second regulating valve is opened. The sandblasting cleaning operation is the same as the water spray cleaning operation. After that, the steel pipe clamping mechanism drives the circular steel pipe to rotate 180°, and the detection and cleaning operations are repeated. BRIEF DESCRIPTION OF THE DRAWINGS

First, the second regulating valve 46 is closed to close the main sand delivery pipe 44, and the first regulating valve 45 is opened to open the main water delivery pipe 43. The water flow in the main water delivery pipe 43 is divided into two streams through the inner water delivery pipe 471 and the outer water delivery pipe 481, and then enters the inner main pipe 473 and the outer main pipe 483 respectively, respectively.

After the circular steel pipe 1 completes the cleaning of the upper half, the driving motor 54 drives the rotating shaft 53 to rotate. The rotating shaft 53 rotates with the driving gear chain 52, and the ring pressing gear 51 and the driving gear chain 52 are meshed, so the driving gear chain 52 will rotate with the circular steel pipe 1. After rotating 180°, the detection mechanism 3 and the cleaning mechanism 4 work again.

[0043] Working principle of the present invention: After starting, the present invention places the circular steel pipe 1 on the fixed block 23, and the screw nut pair 331 and the second hydraulic cylinder 477 drive the detection mechanism 3, the external cleaning device 48 and the internal cleaning device 47 to move. After power is turned on, the two electric needles 31 mark adjacent points on the surface of the circular steel pipe 1. When a bulge or depression is detected, the potential difference between the surface of the circular steel pipe 1 and the electric needle 31 will change compared to when no bulge or depression is detected, and it is displayed by a voltmeter. By converting the signal detected by the electric needle 31 into a change in the angle of the inner nozzle 474 and the outer nozzle 484, in the initial state, the inner nozzle 474 maintains an angle of spraying to the upper left through the first hydraulic cylinder 475, and the outer nozzle 484 maintains an angle of spraying to the lower left through the third hydraulic cylinder 485. Degrees, for detected protrusions or depressions, after the outer nozzle 484 passes the highest point, the third hydraulic cylinder 485 drives the outer nozzle 484 to change its spray angle from spraying toward the lower left to spraying toward the lower right, while the inner nozzle 474, driven by the first hydraulic cylinder 475, changes its spray angle from the upper left to the upper right, so that the angles formed by the protrusions or depressions can be better cleaned. After the cleaning is completed, the water inside flows out along the circular steel pipe 1, and the water on the outer wall flows out along the flat baffles 24 on both sides. After the water cleaning is completed, the first regulating valve 45 is closed and the second regulating valve 46 is opened. The sandblasting cleaning operation is the same as the water spray cleaning operation. After that, the steel pipe clamping mechanism 5 drives the circular steel pipe 1 to rotate 180°, and the detection and cleaning operations are repeated.
