Description

Technical Field

[0001] The invention relates to the technical field of conveying devices, in particular to a continuous pipe conveying device for electromagnetic zinc plastering. Background Art

[0002] Hot-dip galvanizing, a common corrosion protection method for steel products, provides a thicker coating, effectively extending the service life of steel products. Two alternating magnetic fields are used: the first generates eddy currents on the inner wall of the steel pipe, maintaining the zinc in a liquid state; the second generates a unidirectional Lorentz force, driving the liquid zinc to flow along the inner wall. The thickness of the galvanized layer is precisely controlled by adjusting the frequency, phase, and current intensity of the two magnetic fields. Special conveying equipment is used to minimize damage to the pipe during transportation.

[0003] A Chinese patent, publicized under the patent number CN110228680B, discloses a continuous elevator conveying device, belonging to the field of material conveying machinery technology. The device comprises a conveyor roller mounted on a frame on one side of the elevator, with a material barrier arm positioned below the conveyor roller, which is supported by a barrier arm top ring. The barrier arm top ring is mounted on a top ring seat, which is connected to the end of the piston rod of a cylinder. The top ring seat is connected to one end of a swing arm driven by a cylinder via a push-pull rod. The other end of the swing arm is provided with a roller that is positioned between the elevator and the conveyor roller when the piston rod is retracted. This invention can solve the problem of existing continuous elevator conveying, where materials are easily dropped or stuck between the conveyor roller and the elevator, causing damage to the equipment and affecting material conveying efficiency.

[0004] A Chinese patent, published under the official account CN104555214B, discloses a continuous lifting and conveying device comprising a pair of first and second chains that move in a circular motion. The first and second chains are each provided with a carrier frame that moves synchronously, creating a cargo space between the first chains. Once cargo is transported to the cargo space, the two synchronously moving carrier frames support the cargo from below and drive it upward onto the chain brackets, where it then moves horizontally for transfer. This process lifts cargo from a low location to a high location, facilitating selection by selectors. The overall structure is simple, low-cost, and easy to install. The chain drive eliminates elastic slippage and maintains an accurate transmission ratio, resulting in high transmission efficiency.

[0005] The above-mentioned and similar existing technologies can, to a certain extent, solve the problem of correcting the deviation of square pipes during inclined transportation. However, most of the existing technologies adjust the pipes by electric push rods, hydraulic cylinders and cylinder-driven clamps. However, the pipes need to be galvanized in a galvanizing bath and then transported through a conveying device for electromagnetic galvanizing. The liquid temperature of the zinc liquid (about 420°C) will cause the insulation aging and winding short circuit of the electric push rod motor due to high temperature, and the hydraulic cylinder seal may soften due to high temperature and cause oil leakage. In addition, the electric push rod and hydraulic cylinder require continuous electrical / liquid power input, and at high temperatures, the aging of the components may be aggravated by their own heat and the ambient temperature. In addition, the electromagnetic device has a strong electromagnetic field, which may affect the electronic components in the cylinder or the pneumatic control system may be interfered with.

[0006] Therefore, the present invention provides an electromagnetic zinc plastering continuous pipe conveying device that can operate stably in a high-temperature environment and clamp and adjust the pipe. Summary of the Invention

[0017] Beneficial effects of the present invention:

[0018] (1) The present invention relates to a continuous pipe conveying device for electromagnetic zinc plastering. When the pipe collides with the resistance member, the second coupling member engages with the first coupling member to transmit power to the transmission shaft, thereby clamping and lifting the pipe. When the pipe maintains a stable conveying state, the second coupling member resets and loses power. This design of on-demand power transmission can not only meet the needs of pipes at different conveying stages, but also effectively save energy and reduce the operating cost of the equipment.

[0019] (2) The continuous pipe conveying device for electromagnetic zinc plating described in the present invention drives the clamp to clamp and press down the pipe through a series of transmission structures such as the output shaft, coupling, bevel gear set, gear rack, etc., which can effectively prevent the pipe from warping and deflecting during transportation. In the process of electromagnetic zinc plating, the smooth transportation of the pipe is very important, which ensures the stability of the pipe transportation and avoids the problem that warping and deflection may cause uneven electromagnetic zinc plating and affect product quality, thereby improving the effect of electromagnetic zinc plating.

[0020] (3) The electromagnetic zinc plastering continuous pipe conveying device described in the present invention can maintain the clamping of the pipe by means of the limit block being engaged in the limit slot when the power of the clamping assembly is lost, thereby ensuring that the pipe can still be stably clamped when there is no power input. When the pipe is conveyed to the adjusting rod, the action of the adjusting rod can cause the clamping assembly to be retracted by the spring and drive another set of clamping assemblies to continue to clamp the pipe, thereby realizing the automatic resetting and alternating operation of the clamping assembly and improving the degree of automation and working efficiency of the equipment.

[0021] (4) The electromagnetic zinc plastering continuous pipe conveying device described in the present invention has a series of purely mechanical transmissions such as the output shaft, coupling, transmission shaft, bevel gear set, gear rack, etc., which makes the mechanical properties of each component stable and can operate stably in harsh industrial environments with higher reliability, thereby avoiding the problem of the electric push rod and hydraulic cylinder causing their working performance to decline when working in a high temperature environment and the problem of the cylinder's weak anti-interference ability.

[0042] Specifically, the fixing frame 52 is used to install the resistance member 51, and the resistance member 51 can be used as a trigger device. When the pipe is warped, it is pushed up and drives the second coupling member 57 to move. The output shaft 53 is used to connect the conveying component 4 and transmit power.

[0043] In this embodiment, the clamping and pressing assembly 7 includes a rack 71 slidably mounted on one side of the mounting plate 6, and a first gear 72 is transmission-connected to one side of the rack 71. A clamping member 73 is symmetrically provided on one side of the mounting plate 6. A connecting rod 74 is rotatably mounted on the side of the clamping member 73 away from the mounting plate 6.

The conveying assembly 4 also includes other conveying rollers. The first roller 41, the second roller 42 and the other conveying rollers are all magnetic rollers. When conveying pipes, the pipes are adsorbed on the first roller 41 by magnetic force and continue to be conveyed.

[0046] In this embodiment, the mounting plate 6 includes a slide groove 61 symmetrically opened on the outside, a limiting slot 63 is opened inside the slide groove 61, a limiting block 62 is fixedly installed on the side of the slide groove 61 close to the second roller 42, and the electromagnetic zinc plastering device 3 includes a zinc plastering groove 31 set on one side. When the limiting block 62 and the fastener 81 are adjusted, the fastener 81 can slide inside the slide groove 61, and the limiting block 62 is used to cooperate with the fastener 81 to limit the adjusting rod 8, and the limiting slot 63 can make the limiting member 75 and the fastener 81 be stuck inside.

[0047] In this embodiment, a clamping assembly 9 is fixedly connected to the inner side of the end of the adjusting rod 8 away from the mounting plate 6. The clamping assembly 9 includes a fixed plate 91 fixedly installed inside the main frame 1. An adjustment groove 92 is provided on the side of the fixed plate 91 away from the second roller 42. A sliding member 93 is slidably installed in the adjustment groove 92. A clamping block 94 is symmetrically provided on the side of the sliding member 93 away from the fixed plate 91. The clamping block 94 is transmission-connected to the sliding block through a connecting rod.

[0048] Specifically, the fixing plate 91 is used to install the clamping assembly 9, the adjusting groove 92 allows the sliding member 93 to slide inside, and the clamping block 94 continues to clamp the pipe when the clamping pressing assembly 7 is reset to ensure that the subsequent pipe is transported to the electromagnetic zinc plastering device 3 and remains in a stable state.

[0049] In this embodiment, the end of the second coupling 57 away from the first coupling 54 is set to a conical surface, the upper end of the resistance member 51 is set to an inclined surface, and the inclined surface of the upper end of the resistance member 51 is provided with evenly distributed balls 511. The balls 511 are in contact with the conical surface of the end of the second coupling 57 away from the first coupling 54, and the balls 511 can rotate with the second coupling 57.

[0050] Working principle: When the square pipe completes the galvanizing work in the galvanizing pool, it will continue to be transported and transported to the electromagnetic zinc plastering device 3 through the conveying device to wipe off the excess zinc liquid on the surface. First, the motor drives the multiple rollers arranged inside the conveying component 4 to rotate through the sprocket and chain, and drives the output shaft 53 to rotate through the sprocket chain through the first roller 41; the pipe is first transported to the bottom of the first roller 41, and under the action of the magnetic roller, the pipe is adsorbed under the first roller 41. When the pipe passes through the first roller 41 and enters the inside of the main frame 1, it is prone to warping and deviation due to the inclined transportation of the pipe. It needs to be corrected and its position adjusted to keep it parallel to the roller and in a stable conveying state.

[0051] Furthermore, when the pipe is warped, the warped end of the pipe will drive the resistance member 51 that contacts it, and make the resistance member 51 slide inside the fixed frame 52, and then the second coupling member 57 slides on the outside of the transmission shaft 55 through the top inclined surface and the ball 511, and then the second coupling member 57 is engaged with the first coupling member 54 and rotates, and then the power is transmitted to the first gear 72 through the transmission shaft 55 and the bevel gear set 56, and then the first gear 72 drives the rack 71 to move longitudinally, and the limit member 75 will slide inside the slide groove 61, and at the same time stretch the spring 76, and then drive the clamping member 73 to move longitudinally and clamp it in the center through the connecting rod 74. At this time, the clamping member 73 corrects the pipeline and presses it down to make it in a stable state. The pipe can continue to be transported through the guide wheel arranged inside the clamping member 73, and at the same time, the pipe is clamped and pressed down by the clamping member 73, avoiding the problem of warping of the pipe during transportation.

[0052] Furthermore, when the clamping and pressing assembly 7 adjusts the pipe to a stable state, the limit member 75 will be stuck in the limit slot 63, so that it continues to clamp the pipe to maintain its stable transportation. At the same time, the resistance member 51 is reset. At this time, the second coupling member 57 loses its resistance force, the spring 76 contracts and drives the second coupling member 57 to reset and disengage it from the first coupling member 54. The transmission shaft 55 loses power, and then the pipe continues to be transported forward. When the pipe is transported to the outside of the second roller 42 and passes through the clamping assembly 9, it will continue to be transported and will conflict with the guide provided at the bottom end of the adjusting rod 8. When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76 and the locking cam 76 is engaged in the locking cam 76. .... When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76. When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76. When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76. When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76. When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76. When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76. When the lever 81 is in the closed position, the spring 76 is engaged in the locking cam 76. When the lever 81 is in the closed position

[0053] Furthermore, the pipe is transported to the electromagnetic zinc plastering device 3, and is electromagnetically zinc plastered through the zinc plastering tank 31. The zinc-plated pipe continues to be transported and undergoes subsequent processing. Then, when the subsequent pipe is transported and triggers the transmission component 5, the clamping and pressing component 7 is driven to clamp the pipe. When the pipe is adjusted to a stable state, the limit block 62 slides to the limit slot 63, and it will be stuck in the limit slot 63 and push out the fastener 81, and then the clamping component 9 is reset by moving the adjusting rod 8, and the subsequent pipe transportation can continue.
