It should be noted that the terms "first," "second," and the like in the description and in the claims of the present application are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order.

One of the preferred embodiments of the present application, as shown in fig. 1 to 12, is a rust removing device for construction pipes, comprising a frame 1, a driving mechanism 3, a plate assembly 4 and a rust removing mechanism 2; the driving mechanism 3 is arranged on the frame 1, the plate component 4 is movably arranged on the frame 1 and is matched and connected with the driving mechanism 3, and the rust removing mechanism 2 is arranged on the frame 1 and is matched and connected with the driving mechanism 3.

Specifically, when the driving mechanism 3 performs the first action during the pipe rust removal, the plate assembly 4 can clamp and fix the pipe and keep the pipe in a static state, and at this time, the rust removal mechanism 2 can prop against the pipe and perform polishing rust removal operation under the driving of the driving mechanism 3.

When the driving mechanism 3 performs the second action, the plate assembly 4 can convey the pipe for a set distance under the action of the driving mechanism 3, and at the moment, the rust removing mechanism 2 can be far away from the pipe, namely, polishing and rust removing of the plate are stopped, so that continuous conveying and rust removing processing of the pipe are realized.

In the above embodiment, as shown in fig. 2 to 4, the rust removing mechanism 2 includes a cylinder 201, a swivel 203 and a plurality of roller assemblies 202, the cylinder 201 is rotatably mounted on the frame 1 and connected with the driving mechanism 3, and a plurality of wedge surfaces are provided in the cylinder 201, and it is understood that, as shown in fig. 6, a plurality of wedge blocks 8 are provided in the cylinder 201, thereby forming the wedge surfaces. While the swivel 203 is rotatably mounted on the frame 1 and cooperates with the frame 1 through the clutch structure 7, the roller assembly 202 is rotatably mounted on the swivel 203 and is located in the cylinder 201, and of course, the roller assembly 202 is preferably elastically rotatably mounted in the cylinder 201, and when the roller assembly 202 is not subjected to other external forces, as shown in fig. 6, the roller assembly 202 and the pipe in the cylinder 201 have a certain interval.

When the driving mechanism 3 performs the first action, the cylinder 201 can rotate under the driving of the driving mechanism 3, and then one end of the roller assembly 202 is extruded through the wedge surface, at this time, the clutch structure 7 is in a limiting state, so that the other end of the roller assembly 202 will rotate under the extrusion action of the wedge surface, until the roller assembly 202 rotates and abuts against the pipe, the clutch structure 7 is in a separating state, namely contacts the limitation of the roller assembly 202, and at this time, the roller assembly 202 can synchronously rotate along with the cylinder 201 along the outside of the pipe. At the same time, the drive mechanism 3 continues to provide power to maintain a steady rotation of the cylinder 201 and roller assembly 202 and to ensure that a proper contact force is maintained between the roller assembly 202 and the pipe to facilitate the sanding of the outside of the pipe by the roller assembly 202.

In this embodiment, as shown in fig. 4, the roller assembly 202 includes a rotating rod 2021, a polishing roller 2022 and a mounting frame 2023, the rotating rod 2021 is rotatably mounted on the rotating ring 203 (through elasticity of torsion springs), the polishing roller 2022 is rotatably mounted on the mounting frame 2023 and cooperates with the rotating rod 2021 through a transmission structure 6, and the mounting frame 2023 is mounted outside the rotating rod 2021.

It should be noted that, as shown in fig. 4, the structure of the transmission structure 6 is various, but not limited to, the following two types:

structure one: the transmission structure 6 comprises two belt wheels and a belt, wherein the two belt wheels are respectively arranged outside the grinding roller 2022 and the rotating rod 2021, and the belt wheels are sleeved outside the two belt wheels.

When the rotating rod 2021 rotates, the polishing roller 2022 can be driven to rotate under the transmission action of the belt wheel and the belt.

And (2) a structure II: the transmission structure 6 includes two sprockets and a chain, the two sprockets are respectively mounted outside the grinding roller 2022 and the rotating rod 2021, and the chain is sleeved between the two sprockets.

When the rotating rod 2021 rotates, the polishing roller 2022 can be driven to rotate under the transmission action of the chain wheel and the chain.

It should be noted that both structures can meet the actual requirements, and those skilled in the art can select according to the actual situation; when belt transmission is adopted, slip may occur when friction force between the grinding roller 2022 and the pipe is excessively large, whereas when chain transmission is adopted, accuracy and stability of transmission are high, so that a transmission structure of a sprocket and a chain is preferably adopted.

Specifically, as shown in fig. 6, a state diagram before polishing is shown; when polishing, the cylinder 201 rotates anticlockwise under the action of the driving mechanism 3, and then the wedge block 8 rotates and extrudes one end of the mounting rack 2023, so that the mounting rack 2023 rotates along with the axial direction of the rotating rod 2021 until the polishing roller 2022 on the other end of the mounting rack 2023 abuts against the outside of the pipe, as shown in fig. 7, the clutch structure 7 on the rotating ring 203 is in a separated state, and then the rotating ring 203 drives the polishing roller 2022 to synchronously rotate along with the cylinder 201, so that the polishing and rust removal are performed on the outside of the pipe along with the rotation of the outside of the cylindrical pipe.

Further, the rotating rod 2021 and the frame 1 may be matched through the transmission member 5, so that the polishing roller 2022 may be driven by the transmission member 5 to rotate along the axial direction. In this way, the frictional travel between the grinding roller 2022 and the pipe can be increased in a unit time, thereby improving the grinding efficiency of the pipe.

In this embodiment, as shown in fig. 3, the specific structure of the transmission member 5 is various, and one embodiment is specifically described below:

the transmission piece 5 comprises an inner gear 502 and an inner gear ring 501, wherein the inner gear 502 is arranged on the rotating rod 2021, and the inner gear ring 501 is arranged on the frame 1 and meshed with the inner gear 502; when the grinding roller 2022 rotates circumferentially, the internal gear 502 and the internal gear ring 501 cooperate with each other, so that the rotating rod 2021 can be driven to rotate, and the grinding roller 2022 can be driven to rotate; it will be appreciated that as shown in fig. 4, when the polishing roller 2022 rotates circumferentially along the outside of the pipe, the polishing roller 2022 rotates itself, thereby realizing double polishing of the pipe and greatly improving polishing efficiency.

Of course, the inner gear 502 and the inner gear ring 501 can also use an inner rotating wheel and an inner friction ring, namely, the inner rotating wheel is arranged on the rotating rod 2021, and the inner friction ring is arranged on the frame 1 and matched with the inner rotating wheel; when the polishing roller 2022 rotates circumferentially, the inner rotating wheel moves along the inner friction ring, and under the action of friction force, the inner rotating wheel rotates to drive the polishing roller 2022 to rotate. The inner wheel and the inner friction ring are not matched with each other, so that the stability of the matching of the inner gear 502 and the inner gear ring 501 is good, and the matching of the inner gear 502 and the inner gear ring 501 is preferably adopted.

In this embodiment, as shown in fig. 8 and 9, the plate assemblies 4 are a pair and are symmetrically distributed up and down, the plate assemblies 4 include a movable plate 402, a clamping plate 401 and a connecting rod 403, the movable plate 402 is connected and matched with the frame 1 through a guiding structure 9, the clamping plate 401 can be elastically mounted on the movable plate 402 through a spring, and the connecting rod 403 is connected with the movable plate 402 and forms a crank block structure with the driving mechanism 3; when the driving mechanism 3 performs the second action, the clamping plate 401 may perform the first process as well as the second process under the driving of the guiding structure 9.

The first process comprises the following steps: as shown in fig. 10, the two clamping plates 401 clamp and fix the pipe vertically in the initial state, and then, the clamped pipe is moved by a set distance by the driving of the guiding structure 9, it can be understood that the clamped pipe is moved by the set distance, so that the polished part of the pipe moves out of the cylinder 201, and the unground part of the pipe moves to the cylinder 201 for the next polishing and rust removal.

The second process is as follows: as shown in fig. 11, the clamping plate 401 may be far away from the pipe and moved by the guiding structure 9 until being reset, that is, moved to a state of initially clamping and fixing the pipe, as shown in fig. 10, to clamp and fix the next polishing and rust removal.

Specifically, as shown in fig. 9, the guide structure 9 includes a guide block 902 and a guide groove 901, the guide groove 901 may be in a parallelogram structure, and the guide block 902 is mounted on the movable plate 402 and slidably engaged with the guide groove 901.

When the guide block 902 is positioned at the lower end of the guide groove 901, the clamping plate 401 can be in a propped state with the pipe; the clamping plate 401 may be remote from the tubing when the guide block 902 is located at the upper end of the guide slot 901. Thereby realizing the movable conveying and resetting of the pipe.

In this embodiment, as shown in fig. 2, the driving mechanism 3 includes a driving device 301, a first transmission assembly 302 and a second transmission assembly 303, the driving device 301 is mounted on the frame 1, an input end of the first transmission assembly 302 is connected with an output end of the driving device 301, an output end of the first transmission assembly 302 is connected with the cylinder 201 in a matching manner, an input end of the second transmission assembly 303 is connected with the first transmission assembly 302 in a matching manner, and an output end of the second transmission assembly 303 is connected with the connecting rod 403 in a matching manner.

The structure and principle of the driving device 301 are common knowledge of those skilled in the art, and a motor is often used.

Specifically, as shown in fig. 2, the first transmission assembly 302 includes an external gear ring 3022 and a driving gear 3021, the driving gear 3021 is mounted at the output end of the driving device 301, and the external gear ring 3022 is mounted outside the cylinder 201 and cooperates with the input end of the second transmission assembly 303.

When the driving device 301 (motor) rotates forward, the motor drives the driving gear 3021 to rotate forward, and the cylinder 201 can rotate under the meshing transmission of the driving gear 3021 and the external gear ring 3022, so that the second transmission assembly 303 is disengaged from the external gear ring 3022.

As shown in fig. 2, the second transmission assembly 303 includes a transmission gear 3031, a worm 3032 and a worm wheel 3033, the worm 3032 is rotatably mounted on the frame 1, the transmission gear 3031 is mounted on an end portion of the worm 3032 through a one-way bearing and is matched with the external gear ring 3022, the worm wheel 3033 is rotatably mounted on the frame 1 and is matched with the worm 3032 through a rotating shaft, and the rotating shaft is connected with the connecting rod 403 through a crank.

It will be appreciated that, as shown in fig. 10, a crank is installed at one end of the rotating shaft, one end of the crank is hinged to the upper end of the connecting rod 403, a slider (not shown) is hinged to the lower end of the connecting rod 403, the slider is horizontally slidably installed on the frame 1, when the rotating shaft rotates, a crank-slider structure is formed, that is, the slider can reciprocate left and right along the frame 1, and the movable plate 402 is vertically slidably sleeved outside the slider.

As shown in fig. 12, the guide block 902 is slidably mounted on the movable plate 402 through a spring, the guide block 902 and the guide groove 901 form a sliding fit, when the movable plate 402 is driven by the slide block to move leftwards (move from D to a direction of the guide groove 901), the guide block 902 moves along the bottom edge of the guide groove 901 which is in a parallelogram shape, when the slide block continues to move, the guide block 902 moves obliquely upwards along the oblique edge of the left side from the bottom edge of the guide groove 901 (move from a to B of the guide groove 901, the depth of the guide groove 901 corresponding to a to B becomes gradually deeper), and when the movable plate 402 moves upwards along the slide block, until the guide block 902 moves to the junction (B) between the left oblique side and the upper side of the guide groove 901, the clamping plate 401 is far away from the pipe, then the guide block 902 moves rightwards (moves from B to C of the guide groove 901), namely the guide block 902 moves rightwards along the upper side of the guide groove 901, so that the clamping plate 401 moves rightwards to reset, finally the guide block 902 enters the oblique side on the right side of the guide groove 901 and moves downwards to the bottom side of the guide groove 901 (moves from C to D of the guide groove 901, the depth of the guide groove 901 corresponding to C to D becomes deep gradually), and at the moment, the movable plate 402 moves downwards along the sliding block, namely the clamping plate 401 moves downwards to reset to clamp and fix the pipe, and returns to the initial position.

The depth of the guide groove 901 corresponding to the positions a to B is gradually deepened, and the depth of the guide groove 901 corresponding to the positions C to D is gradually deepened, so that under the reciprocating movement action of the sliding block, the movable plate 402 and the clamping plate 401 are driven by the guide block 902 to reciprocate along the direction of the ABCD, and further clamping and loosening of the pipe are realized.

It should be noted that the pipe passing through the cylinder 201 will overlap the frame 1, and the pipe is located at the center of the cylinder 201, that is, when the two clamping plates 401 move away from each other, the pipe will not move down to contact with the lower clamping plate 401.

When the driving device 301 rotates reversely, the one-way bearing is in a meshed state, so that the worm 3032 can rotate under the meshing action of the transmission gear 3031 and the external gear ring 3022, and the worm 3032 acts on the worm wheel 3033 to drive the rotating shaft to rotate.

In this embodiment, as shown in fig. 5, the clutch structure 7 includes a clutch block 701 and a clutch groove 702, and the mounting manners of the clutch block 701 and the clutch groove 702 are various, including but not limited to the following two types:

Mode two: the clutch block 701 is elastically slidably mounted to the frame 1 by a spring, and the clutch groove 702 is provided in the swivel 203.

It can be appreciated that when the clutch block 701 is matched with the clutch groove 702, the clutch structure 7 is in a limit state; when the clutch block 701 is disengaged from the clutch groove 702, the clutch structure 7 is in a disengaged state.

It should be noted that, when the clutch block 701 is matched with the clutch groove 702, the clutch structure 7 is in a limiting state, that is, the clutch block 701 is located in the clutch groove 702 at this time, so as to limit the swivel 203, and the limiting force is the largest at this time; when the clutch block 701 is separated from the clutch groove 702, the clutch structure 7 is in a separated state, although the clutch block 701 and the clutch groove 702 are separated at this time, the swivel 203 is not in a completely free state, that is, a certain friction resistance exists between the swivel 203 and the frame 1, so that the swivel 203 synchronously rotates along with the extrusion of the cylinder 201, and the polishing roller 2022 rotates circumferentially along the outside of the pipe, and simultaneously, the polishing roller 2022 rotates under the action of the transmission structure 6 and the transmission piece 5, thereby realizing double polishing of the pipe, greatly improving polishing efficiency, greatly reducing the time required by polishing, and improving production efficiency. Meanwhile, the clutch structure 7 is reasonable in design, can effectively limit and control the friction resistance between the swivel 203 and the frame 1, and ensures the stable rotation of the swivel 203.

The working principle of the invention is as follows:

firstly, a cylindrical pipe to be polished and derusted is penetrated into a cylinder 201 from a frame 1, before penetrating, as shown in fig. 11, an upper clamping plate 401 and a lower clamping plate 401 are in a far away state, namely, the pipe cannot be penetrated and interfered, then a motor is started to rotate reversely, the motor drives a driving gear 3021 and further drives an outer tooth ring 3022 to rotate reversely, a one-way bearing on the driving gear 3031 is in a meshing state, a worm 3032 can rotate under the meshing action of the driving gear 3031 and the outer tooth ring 3022, the worm 3032 acts on a worm wheel 3033 and drives a rotating shaft to rotate, two clamping plates 401 are made to be close to each other to clamp and fix the pipe under the action of a crank slider, and a guide block 902 can be located at the right end position of the bottom edge of a guide groove 901.

Then the motor is started to rotate positively, the motor drives the driving gear 3021 to rotate positively, the cylinder 201 can rotate under the meshing transmission of the driving gear 3021 and the outer gear ring 3022 (at this time, although the transmission gear 3031 rotates under the action of the outer gear ring 3022, the unidirectional bearing on the transmission gear 3031 is in a free state, so that the crank block structure cannot operate, that is, the clamping plate 401 keeps still and clamped at all times, the spring force on the clamping plate 401 is large enough to stably clamp the polished pipe), as shown in fig. 6, the cylinder 201 rotates anticlockwise, the wedge block 8 rotates and presses one end of the mounting frame 2023, so that the mounting frame 2023 rotates along with the axial direction of the rotating rod 2021 until the polishing roller 2022 on the other end of the mounting frame 2023 abuts against the outside of the pipe, as shown in fig. 7, the clutch structure 7 on the rotating ring 203 is in a separated state, and then the rotating ring 203 drives the polishing roller 2022 to rotate synchronously along with the cylinder 201, and then the outside of the pipe is polished; of course, when the grinding roller 2022 rotates circumferentially, the internal gear 502 and the internal gear ring 501 cooperate with each other, so as to drive the rotating rod 2021 to rotate, and drive the grinding roller 2022 to rotate through the transmission structure 6; it will be appreciated that as shown in fig. 4, when the polishing roller 2022 rotates circumferentially along the outside of the pipe, the polishing roller 2022 rotates itself, thereby realizing double polishing of the pipe and greatly improving polishing efficiency.

After the part of the pipe located in the cylinder 201 is polished, the motor is started to rotate reversely, at this time, the sliding block drives the movable plate 402 to move leftwards, namely, the guide block 902 moves leftwards along the right end of the bottom edge of the guide groove 901, so that the pipe clamped by the clamping plate 401 moves leftwards for conveying, it can be understood that the clamped pipe is moved by a set distance, the polished part of the pipe moves out of the cylinder 201, the unground part of the pipe moves to the cylinder 201 for the next polishing and rust removal, and finally the clamping plate 401 returns to the initial clamping position. And then starting the motor to perform forward rotation polishing, namely repeating the steps. And then realize automatic polishing and the transport of tubular product, labour saving and time saving just improves work efficiency. Of course, the pipe can be conveyed repeatedly, so as to reach the required conveying distance.

When the motor rotates reversely, the cylinder 201 rotates along the pointer, so that the wedge block 8 is far away from the mounting frame 2023, and the mounting frame 2023 loses extrusion force, rotates under the action of elasticity and is separated from the pipe, and interference is not caused to moving and conveying of the pipe; of course, if the wedge block 8 continues to rotate and the mounting frame 2023 contacts and presses, the mounting frame 2023 also rotates towards the direction away from the pipe, so that no interference is caused to the moving and conveying of the pipe.
