Description

Technical Field

[0001] This invention belongs to the field of pipe testing technology, and in particular relates to a pipe surface testing device. Background Technology

[0002] Currently, after pipes are formed through a series of processes, their outer surfaces need to be inspected one by one. The current inspection methods are: workers visually inspect each pipe individually, or workers manually move the pipes onto inspection equipment and rotate them for surface inspection. For example, patent number CN202020851246.0, entitled "A Surface Inspection Device for Galvanized Steel Strip Pipes," discloses a surface inspection device. However, this device can only inspect a single pipe, resulting in low efficiency. It requires manual feeding of the pipes onto the fixtures, and the pipes cannot be rotated, making it unsuitable for comprehensive inspection. Therefore, a mechanized device integrating the above processes needs to be designed to address the problems of high labor intensity, low efficiency, and inconsistent and inaccurate inspection results associated with manual inspection. Summary of the Invention

[0010] The slide plate is also fixedly equipped with two vertically arranged first linear drive elements, each of which is provided with a horizontally arranged second linear drive element, and each of the second linear drive elements is provided with a stop bar.

[0011] As a further improvement, the pipe inspection support includes a support plate fixedly installed at the end of each of the feeding support plates. Two support wheels are rotatably installed on the support plate, which are arranged vertically and vertically corresponding to the pipe rotation drive mechanism. A first guide slope is provided at the top corners of both ends of each support plate.

[0012] Material retention plates are fixedly installed on the side of the two support plates that are close to each other. The material retention plate has a pipe retention groove at the incoming end and a second material guiding slope that is coplanar with the first material guiding slope at the outgoing end.

[0013] As a further improvement, the eccentric rotary synchronous power mechanism includes drive arms rotatably mounted on the two material feeding support plates, a drive shaft driven by a power component is provided between the two drive arms, a bidirectional sliding mechanism is provided on the drive arms, and the connection between the bidirectional sliding mechanism and the drive arms is offset from the center of the drive shaft; the push plate is fixedly mounted on the bidirectional sliding mechanism and cooperates with the material retention plate and the support plate, and the push plate is provided with a plurality of material troughs arranged in an array along the length direction.

[0014] As a further improvement, each of the feeding support plates is fixedly mounted with a drive guide plate, the drive guide plate is provided with square-arranged guide slots, and the drive arm is rotatably mounted on the drive guide plate.

[0015] The drive arm, which corresponds to the guide groove, has an elongated hole. Both the elongated hole and the guide groove are equipped with rollers, and the two rollers are assembled and connected to the bidirectional sliding mechanism.

[0016] As a further improvement, the bidirectional sliding mechanism includes a connecting shaft connected to the two rollers, a first slider fixedly mounted on the connecting shaft, the first slider being vertically slidably mounted on the second slider, and the second slider being horizontally slidably mounted on the feeding support plate; the push plate is fixedly mounted on the first slider.

[0017] As a further improvement, the frame opening adjustment mechanism includes a connecting arm fixedly connected to each of the support plates and located downstream of the first guide slope on the discharge end, and a connecting plate fixedly installed on the frame. Two opposing sliding blocks are slidably installed on the connecting plate, and the two sliding blocks are correspondingly and fixedly connected to the two connecting arms.

[0018] As a further improvement, the pipe rotation drive mechanism includes a slide table that is vertically slidably mounted on the connecting plate, a mounting seat that is horizontally slidably mounted on the slide table, and a pressure roller driven by a drive element on the mounting seat. The pressure roller and the support wheel are arranged vertically and vertically respectively.

[0019] As a further improvement, the pipe discharge mechanism includes a discharge rack located downstream of the connecting arm, the discharge rack being provided with an inclined discharge guide plate, and a discharge baffle fixedly connected to the connecting arm above the discharge guide plate.

[0020] The discharge guide plate is provided with a discharge hole, and a sealing plate is provided at the corresponding position of the discharge hole. A third linear drive element is provided between the sealing plate and the frame.

[0021] A fourth linear drive element is located upstream of the connecting arm and fixedly installed on the support plate. The fourth linear drive element drives a receiving and discharging baffle that works in cooperation with the first guiding inclined surface.

[0022] After adopting the above technical solution, the effect of the present invention is as follows:

[0023] The pipe surface inspection equipment includes a frame, on which a feeding rack is slidably mounted. A pipe combing and feeding mechanism is slidably mounted on the frame directly above the feeding rack. A pipe inspection support is located on the feeding rack downstream of the pipe combing and feeding mechanism. An eccentric rotary synchronous power mechanism drives a push plate to transfer the pipes one by one from the feeding rack to the pipe inspection support. A frame opening adjustment mechanism is located between the frame and the pipe inspection support. A pipe rotation drive mechanism is located between the frame opening adjustment mechanism and the pipe inspection support. Inspection elements facing the pipes are located on the pipe inspection support at both ends of the pipe rotation drive mechanism and on the pipe combing and feeding mechanism. The frame opening... A pipe feeding mechanism is provided between the adjustment mechanism and the frame. Based on the above structure, during operation, the pipe surface inspection equipment places multiple pipes in batches on the feeding rack. Then, the pipe sorting and feeding mechanism sorts and feeds the pipes one by one. Afterwards, the push plate driven by the eccentric rotation synchronous power mechanism transfers the pipes one by one to the pipe inspection support. Then, the pipe rotation drive mechanism drives the individual pipes to rotate, and during the rotation, the detection element completes the inspection of the pipe surface (including the outer circumference and both ends of the pipe). Finally, the pipe feeding mechanism outputs the inspected pipes. Before the above operation, the width of the feeding rack and the pipe inspection support is adjusted by the frame opening adjustment mechanism to meet the inspection requirements of pipes of different lengths.

[0024] In summary, the pipe surface inspection equipment enables mechanized feeding, inspection, and discharge of pipes one by one, with high continuity of operation, effectively improving work efficiency and greatly reducing the labor intensity of workers. At the same time, the pipe surface inspection has high consistency and accuracy.

[0025] The feeding rack includes two feeding support plates arranged at intervals and slidably mounted on the frame. The top of the feeding support plate has a feeding ramp that slopes downward toward the pipe inspection support frame. A feeding trough is provided on the feeding support plate at the lower end of the feeding ramp. A pipe guide plate is fixedly installed on the feeding ramp, and a feeding baffle is adjusted and installed on the pipe guide plate. During feeding, the pipe guide plate guides the pipe toward the feeding trough, and the feeding baffle blocks the pipe to ensure that both ends of the pipe can enter the feeding trough. The width of the feeding rack can be adjusted by sliding the feeding support plate to meet the feeding requirements of pipes of different lengths. The structure is simple, the feeding effect is good, and it provides a guarantee for subsequent effective and reliable feeding.

[0026] The pipe combing and feeding mechanism includes a slider that slides horizontally between two feeding baffles and is equipped with a detection element. A sliding plate is vertically mounted on the slider, and a combing plate is fixedly mounted on the sliding plate. The distance between the combing plate and the pipe guide plate is less than the outer diameter of a single pipe. Two vertically arranged first linear drive elements are also fixedly mounted on the sliding plate. Each first linear drive element has a horizontally arranged second linear drive element, and each second linear drive element has a stop bar. Thus, when feeding multiple pipes one by one from the feeding rack, the sliding of the slider and sliding plate adjusts the combing plate to a suitable working position. Then, the combing plate combs the multiple pipes, preventing... The pipes are stacked to allow each pipe to pass through one by one. Through the alternating operation of two sets of first and second linear drive elements and a stop bar, the pipes are guided one by one into the discharge trough. Specifically, after one set of first and second linear drive elements and the stop bar blocks the pipe, another set of first linear drive elements rises, and the second linear drive element drives the stop bar upstream. Then, the first linear drive element descends and the stop bar blocks the next pipe. Once the pipe in the discharge trough has been moved, the stop bar returns to its original position, and the pipe slides into the discharge trough. This process is repeated to complete the discharge of each pipe. The structure is simple, and the pipe discharge effect is good.

[0027] The pipe inspection support frame includes a support plate fixedly installed at the end of each feeding support plate. Two support wheels are rotatably mounted on the support plate, corresponding vertically to the pipe rotation drive mechanism. Each support plate has a first guide slope at its apex. A material retention plate is fixedly installed on the side of the two support plates that are close to each other. The material retention plate has a pipe retention groove at its inlet end and a second guide slope coplanar with the first guide slope at its outlet end. Therefore, when inspecting each pipe individually, the support wheels guide the incoming pipe. After being supported, the pipe is driven to rotate on the support roller by the pipe rotation drive mechanism. During the process of transferring the pipe to the support roller by the push plate, the first guide slope is used to avoid interference with the pipe during the transfer. The pipe is transferred and temporarily stored by the pipe retention groove on the material retention plate. That is, when the pipe is inspected, the pipe delivered by the push plate is temporarily stored in the pipe retention groove. After the pipe is inspected, the temporarily stored pipe is sent to the support roller by the push plate. The next pipe to be inspected is sent from the feeding rack to the pipe retention groove by the push plate, which lays the foundation for improving the continuity of work.

[0028] The eccentric rotary synchronous power mechanism includes drive arms rotatably mounted on two feeding support plates. A drive shaft driven by a power component is located between the two drive arms. A bidirectional sliding mechanism is provided on the drive arms, with the connection point between the bidirectional sliding mechanism and the drive arms offset from the center of the drive shaft. A push plate is fixedly mounted on the bidirectional sliding mechanism and cooperates with a material retention plate and a support plate. The push plate has multiple material troughs arranged in an array along its length. Therefore, when transferring the pipe material in the feeding troughs, the power component drives the drive shaft to rotate, which in turn drives the bidirectional sliding mechanism and drive arms to rotate. The bidirectional sliding mechanism slides horizontally and vertically to meet the requirement of 360-degree rotation of the drive arms. Simultaneously, the bidirectional sliding mechanism drives the push plate to move. Specifically, the push plate moves based on the pipe material feeding direction. The mechanism moves downwards, towards the discharge trough, upwards, and towards the pipe placement trough. During the downward movement, the push plate moves to below the pipe in the discharge trough. During the upward movement, it receives the pipe through the material trough on the push plate, carrying away one pipe in the discharge trough during the continuous upward movement. Then, another pipe is sent into the discharge trough. At the same time, during the movement towards the pipe placement trough and downward movement, the push plate sends the pipe to the pipe placement trough on the material placement plate. This process is repeated to push the next pipe. Meanwhile, the pipe in the pipe placement trough is sent to the support roller through another material trough on the push plate. The next pipe is then simultaneously transferred to the pipe placement trough. This eccentric rotary synchronous power mechanism provides good synchronous drive for the two push plates, achieving the purpose of acting on both ends of the pipe and completing the mechanized transfer of pipes one by one.

[0029] Each feeding support plate is fixedly equipped with a drive guide plate, which has square guide slots. The drive arm is rotatably mounted on the drive guide plate. The drive arm corresponding to the guide slot has an elongated hole, and both the elongated hole and the guide slot have rollers. The two rollers are assembled and connected to the bidirectional sliding mechanism. Thus, during operation, the movement of the rollers is guided by the square guide slots, thereby limiting the movement trajectory of the bidirectional sliding mechanism driven by the drive arm and the push plate. This ensures that the push plate accurately carries away the pipe in the feeding slot and accurately delivers the pipe to the pipe retention slot and the support roller.

[0030] Because the bidirectional sliding mechanism includes a connecting shaft connected to two rollers, a first slider is fixedly installed on the connecting shaft, the first slider is vertically slidably installed on the second slider, and the second slider is horizontally slidably installed on the feeding support plate; the push plate is fixedly installed on the first slider, so when the drive arm moves along the guide groove through the rollers, the corresponding sliding of the first slider and the second slider not only does not affect the drive of the eccentric rotation synchronous power mechanism, but also effectively ensures that the push plate transfers the pipe.

[0031] The frame opening adjustment mechanism includes a connecting arm fixedly connected to each support plate and located downstream of the first guide slope at the discharge end, as well as a connecting plate fixedly installed on the frame. Two opposing sliding blocks are slidably installed on the connecting plate. The two sliding blocks are correspondingly set and fixedly connected to the two connecting arms. Thus, when adjusting the width of the feeding rack and the pipe inspection support rack according to the pipe length, the opposing sliding blocks drive the two connecting arms to move closer or further apart, thereby driving the support plate to move. Since the support plate is connected to the feeding support plate, it can drive the feeding support plate to slide on the frame, achieving the effect of synchronously adjusting the working width of the feeding rack and the pipe inspection support rack, as well as the consistency of adjustment accuracy.

[0032] The pipe rotation drive mechanism includes a slide table vertically slidably mounted on a connecting plate, a mounting seat horizontally slidably mounted on the slide table, and a pressure roller driven by a drive element on the mounting seat. The pressure roller and the support roller are arranged vertically and vertically respectively. Thus, when the pipe is rotated, the drive element drives the pressure roller to rotate, and the pressure roller drives the pipe placed on the support roller to rotate. The structure is simple, and the rotation drive effect of the pipe is good, providing conditions for comprehensive inspection of the pipe's circumference.

[0033] The pipe discharge mechanism includes a discharge rack located downstream of the connecting arm, an inclined discharge guide plate, and a discharge baffle fixedly connected to the connecting arm above the discharge guide plate. The discharge guide plate has a discharge hole, and a sealing plate is positioned corresponding to the discharge hole. A third linear drive element is located between the sealing plate and the frame. A fourth linear drive element is located upstream of the connecting arm and fixedly installed on the support plate. This fourth linear drive element drives a receiving and discharging baffle that works in conjunction with the first guide slope. After the pipe inspection is completed, the push plate moves the pipe on the support roller and blocks it through the receiving and discharging baffle. Then, the fourth linear drive element moves the receiving and discharging baffle and releases the pipe. When the pipe is qualified, it is guided out through the discharge guide plate. If the pipe is unqualified, the third linear drive element moves the sealing plate downwards and it leaks through the discharge hole. The structure is simple and achieves separate discharge of qualified and unqualified products. Attached Figure Description
