DETAILED DESCRIPTION

[0027] Embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0028] The construction pipe rust removal equipment according to the embodiment of the present application is described below with reference to the accompanying drawings.

[0029] like Figure 1-Figure 8 As shown, the construction pipe rust removal equipment of the embodiment of the present application includes a support frame 10, a feeding assembly 20, a rust removal device 30 and a polishing assembly 40.

[0030] The feeding assembly 20 and the rust removal device 30 are arranged side by side on the support frame 10, wherein the feeding assembly 20 cooperates with the rust removal device 30 to supply pipes to the rust removal device. The rust removal device 30 includes a cylinder 31, a plurality of rust removal assemblies 32, a first drive mechanism 33, a second drive mechanism 34 and a first transmission mechanism 35.

[0031] The cylinder 31 is rotatably arranged on the support frame 10, and a plurality of material taking ports 301 are provided on the cylinder 31, wherein the plurality of material taking ports 301 are distributed in a circular array. A plurality of rust removal components 32 are arranged in a circular array in the cylinder 31, and are distributed one-to-one with the plurality of material taking ports 301. For example, the plurality of rust removal components 32 may be 4, 5, 6, 7, 8, 9 rust removal components 32, etc. The specific number of rust removal components 32 may be selected according to the actual situation, and is not limited here, and the number of rust removal components 32 is the same as the number of material taking ports 301.

[0032] The first driving mechanism 33 is disposed on the support frame 10, and the output end of the first driving mechanism 33 is connected to one end of the cylinder 31, wherein the first driving mechanism 33 is used to drive the cylinder 31 to rotate. The second driving mechanism 34 is disposed in the cylinder 31, and the output end of the second driving mechanism 34 is respectively connected to the plurality of rust removal components 32 through the first transmission mechanism 35, wherein the second driving mechanism 34 is used to drive the first transmission mechanism 35 to drive the plurality of rust removal components 32 to move synchronously.

[0033] It should be noted that the first driving mechanism 33 and the second driving mechanism 34 described in this embodiment are both driving motors.

[0034] The polishing assembly 40 is arranged on the support frame 10 and half surrounds the cylinder 31. The polishing assembly 40 cooperates with a plurality of rust removal assemblies 32 to continuously perform rust removal on a plurality of pipes.

[0035] Specifically, when it is necessary to polish and remove rust from building pipes, the relevant staff can first place a batch of pipes (i.e., multiple pipes) in the feeding assembly 20. Then, the staff controls the first driving mechanism 33 to drive the cylinder 31 to drive the multiple rust removal assemblies 32 to rotate, and when the material taking port 301 on the cylinder 31 rotates to the material outlet of the feeding assembly 20, the pipes in the feeding assembly 20 fall into the material taking port 301.

[0036] As the cylinder 31 rotates, the pipes in the material taking port 301 come into contact with the polishing assembly 40 and are polished by the polishing assembly 40. At this time, the other material taking port 301 continues to take materials and comes into contact with the polishing assembly 40 for polishing (it should be noted that during the rotation of the cylinder 31, the number of pipes in contact with the polishing assembly 40 may be 2, 3, 4 pipes, etc., and the specific number of pipes in contact may be determined according to the number of material taking ports 301 opened).

[0037] At the same time, the staff controls the second driving mechanism 34 to drive the first transmission mechanism 35 to drive multiple rust removal components 32 to move synchronously. At this time, the rust removal components 32 drive the pipe to rotate and cooperate with the polishing component 40 to polish the pipe. In this way, the rust removal operation can be carried out on multiple pipes without interruption, which greatly improves the efficiency and production capacity of the rust removal operation.

[0038] When the polished pipe is separated from the polishing assembly 40, the polished pipe falls under its own gravity and moves out from the material taking port 301. Thus, the material can be automatically loaded and unloaded without excessive manual intervention, which greatly reduces the burden on workers.

[0039] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 5 As shown, the feed assembly 20 may include a feed trough 21 and a baffle plate 22, wherein the feed trough 21 is arranged obliquely downward on the support frame 10, and the outlet end of the feed trough 21 is arranged close to the cylinder 31, so that the pipe located in the feed trough 21 can roll out from the outlet end under the action of its own gravity. Among them, the inclination angle of the feed trough 21 can be set according to actual conditions and is not limited here. The baffle plate 22 is arranged in the feed trough 21 close to the outlet of the feed trough 21. It should be noted that the baffle plate 22 described in this embodiment is L-shaped, and the distance between the bottom surface of the L-shaped baffle plate 22 and the bottom of the feed trough 21 is slightly larger than the diameter of the pipe, that is, the distance between the L-shaped baffle plate 22 and the bottom of the feed trough 21 is only enough for one pipe to move out of the feed trough 21.

[0040] It should be noted that the distance between the outlet end of the feed trough 21 and the barrel 31 described in this embodiment is smaller than the diameter of the pipe. This design can prevent the pipe in the feed trough 21 from falling from the gap between the feed trough 21 and the barrel 31.

[0041] It is understandable that when the staff puts a large amount of pipes into the feeding trough 21, the pipes removed from between the L-shaped baffle plate and the bottom of the feeding trough 21 hit the cylinder 31. As the cylinder 31 rotates, the pipes fall into the material taking port 301.

[0042] In one embodiment of the present application, Figure 4-Figure 8 As shown, the rust removal assembly 32 may include two support cylinders 321 , a polishing roller 322 , two limit mechanisms 323 , two tensioning mechanisms 324 and two second transmission mechanisms 325 .

[0043] The two support cylinders 321 are symmetrically arranged on the inner walls at both ends of the cylinder body 31 and are located below the middle of the material taking port 301 .

[0044] The rotating shafts at both ends of the polishing roller 322 respectively penetrate the corresponding supporting cylinder 321 and are rotatably connected to the two end walls of the cylinder body 31. That is, the rotating shafts at both ends of the polishing roller 322 are rotatably connected to the two end walls of the cylinder body 31 respectively.

[0045] The two limiting mechanisms 323 are symmetrically distributed on both sides of the polishing roller 322 , and each limiting mechanism 323 is rotatably connected to the two supporting cylinders 321 , respectively. Each limiting mechanism 323 includes two driving arms 3231 , a supporting shaft 3232 , a supporting plate 3233 and a plurality of driving wheels 3234 .

[0046] Among them, one end of the two driving arms 3231 is rotatably mounted on the corresponding support tube 321, and the two ends of the support shaft 3232 are rotatably connected to the other ends of the two driving arms 3231, that is, one end of the support shaft 3232 is rotatably connected to the other end of one of the driving arms 3231, and the other end of the support shaft 3232 is rotatably connected to the other end of the other driving arm 3231.

[0047] The support plate 3233 is fixedly arranged between the two driving arms 3231, and a plurality of driving wheels 3234 are equidistantly arranged side by side on the support shaft 3232. For example, the plurality of driving wheels 3234 can be 3, 4, 5, 6, 7, 8, 9, 10 driving wheels 3234, etc. The specific number of driving wheels 3234 can be selected according to actual conditions and is not limited here.

[0048] The two tensioning mechanisms 324 are symmetrically arranged in the cylinder 31, and the two tensioning mechanisms 324 are respectively fixedly connected to the corresponding support plates 3233. One end of the two second transmission mechanisms 325 is respectively connected to one end of the corresponding support shaft 3232, and the other end of the two second transmission mechanisms 325 is respectively connected to one end of the rotating shaft of the polishing roller 322.

[0049] In order to clearly explain the above embodiment, in one embodiment of the present application, as Figure 5 , Figure 7 and Figure 8 As shown, the tensioning mechanism 324 may include a fixing plate 3241 and a plurality of springs 3242 , wherein the fixing plate 3241 is fixedly disposed in the cylinder 31 .

[0050] Multiple springs 3242 are equidistantly arranged side by side between the fixing plate 3241 and the supporting plate 3233, that is, the two ends of the spring 3242 are respectively fixedly connected to the fixing plate 3241 and the supporting plate 3233. Among them, the multiple springs 3242 can be 2, 3, 4, 5, 6 springs 3242, etc. The specific number of settings can be selected according to actual conditions and is not limited here.

[0051] It is understandable that when the pipe enters the material taking port 301, the pipe is directly pressed on the driving wheels 3234 in the two limiting mechanisms 323 under the action of its own gravity. As the cylinder 31 rotates, the pipe first contacts the arc-shaped bracket 41 in the polishing assembly 40, and is squeezed by the arc-shaped bracket 41. The compressed pipe applies pressure to the driving wheels 3234 in the two limiting mechanisms 323 and pushes the corresponding driving arms 3231 to flip. The flipped driving arms 3231 compress the springs 3242 through the support plates 3233, and the springs 3242 also apply an opposite force to the pipe, so that the pipe fits tightly with the arc-shaped polishing sheet 42 in the polishing assembly 40 during the rotation of the cylinder 31, so as to be polished by the arc-shaped polishing sheet 42.

[0052] Further, in one embodiment of the present application, Figure 6-Figure 8 As shown, the second transmission mechanism 325 may include a driving gear 3251 , a transmission gear 3252 and a belt transmission component 3253 .

[0053] The driving gear 3251 is sleeved on the supporting shaft 3232 , the transmission gear 3252 is rotatably disposed on the driving arm 3231 , and the transmission gear 3252 is meshed with the driving gear 3251 .

[0054] The belt transmission component 3253 is connected to a rotating shaft at one end of the polishing roller 322 and a rotating shaft of the transmission gear 3252 respectively.

[0055] It should be noted that the belt transmission component 3253 described in this embodiment may include a first pulley (not specifically marked in the figure), a second pulley (not specifically marked in the figure) and a belt (not specifically marked in the figure), wherein the first pulley is sleeved and fixed on the rotating shaft at one end of the polishing roller 322, and the second pulley is arranged on the rotating shaft of the transmission gear 3252, that is, the second pulley is coaxially arranged with the transmission gear 3252, and the belt is sleeved on the first pulley and the second pulley.

[0056] It can be understood that when the polishing roller 322 rotates, the rotating polishing roller 322 drives the transmission gear 3252 to rotate through the belt transmission component 3253, and the rotating transmission gear 3252 drives the support shaft 3232 to rotate in the opposite direction through the driving gear 3251, and the rotating support shaft 3232 drives the pipe to rotate through the driving wheel 3234, see Figure 5 It can be seen that the pipe and the polishing roller 322 rotate in opposite directions. This arrangement makes it easier for the polishing roller 322 to apply a grinding and polishing force to the pipe.

[0057] In one embodiment of the present application, Figure 4-Figure 6 As shown, the first transmission mechanism 35 may include a driving gear 351 and a plurality of driven gears 352 , wherein the driving gear 351 is connected to the output end of the second driving mechanism 34 .

[0058] The plurality of driven gears 352 are respectively connected to the other end of the rotating shaft of the corresponding polishing roller 322, and the plurality of driven gears 352 are respectively meshed with the driving gear 351. It should be noted that the number of the plurality of driven gears 352 described in this embodiment is the same as the number of the polishing roller 322, and they correspond one to one.

[0059] In one embodiment of the present application, Figure 1-Figure 3 , Figure 5 As shown, the polishing assembly 40 may include an arc-shaped bracket 41 and an arc-shaped polishing sheet 42, wherein the arc-shaped bracket 41 is fixedly arranged on the support frame 10, and the arc-shaped bracket 41 semi-surrounds the cylinder 31, and the arc-shaped polishing sheet 42 is detachably arranged on the inner wall of the arc-shaped bracket 41. It should be noted that the arc-shaped polishing sheet described in this embodiment can also be replaced by an arc-shaped sandpaper sheet.

[0060] It should be noted that the arc-shaped polishing sheet 42 described in this embodiment is detachably arranged on the inner wall of the arc-shaped bracket 41, which is convenient for installation and replacement of the arc-shaped polishing sheet 42. For example, the arc-shaped polishing sheet 42 can be connected to the arc-shaped bracket 41 by means of clamping, riveting or threaded fasteners (screws, bolts or bolts).

[0061] Specifically, when it is necessary to polish and remove rust from the pipes in the feed trough 21, the staff can control the first driving mechanism 33 to drive the cylinder 31 to rotate. During the rotation of the cylinder 31, the pipes in the feed trough 21 enter the corresponding material taking port 301 in turn and fall between the two limiting mechanisms 323 (i.e., between the two sets of driving wheels 3234 (each set of driving wheels includes a plurality of driving wheels 3234)). As the cylinder 31 rotates, the pipes in the material taking port 301 first contact with the arc. The tube is compressed and exerts pressure on the two sets of driving wheels 3234. The two sets of driving wheels 3234 are compressed and expand. At this time, the driving wheels 3234 drive the driving arms 3231 to flip over through the corresponding support shafts 3232. The flipped driving arms 3231 compress the springs 3242 through the support plates 3233. The springs 3242 also exert an opposite force on the two sets of driving wheels 3234, so that the driving wheels 3234 are in close contact with the tube.

[0062] Since the two sets of driving wheels 3234 are expanded toward both sides by the extrusion force of the pipe, the pipe moves downward and contacts the polishing roller 322. As the cylinder 31 rotates, the pipe contacts the arc-shaped polishing sheet 42 after passing the end of the arc-shaped bracket 41.

[0063] At the same time, the staff can control the second driving mechanism 34 to drive the driving gear 351 to rotate (the direction of rotation can be seen in Figure 5As shown in the figure, the rotating driving gear 351 drives the corresponding polishing rollers 322 to rotate through multiple driven gears 352 to polish and remove rust on the pipe. The rotating polishing roller 322 drives the transmission gear 3252 to rotate through the belt transmission component 3253, and the rotating transmission gear 3252 drives the support shaft 3232 to rotate in the opposite direction through the driving gear 3251, thereby driving the driving wheel 3234 to drive the pipe and the polishing roller to rotate in the opposite direction.

[0064] At the same time, when the polishing roller 322 polishes the pipe during the rotation of the cylinder 31, the pipe driven by the two sets of driving wheels 3234 is in contact with the arc-shaped polishing sheet 42, so the arc-shaped polishing sheet 42 will also polish and remove rust on the pipe during the polishing roller 322 polishing, thereby effectively improving the efficiency of the rust removal operation. In addition, as the cylinder 31 rotates, multiple adjacent pipes will contact the arc-shaped polishing sheet 42 and be polished and removed rust by the arc-shaped polishing sheet 42 and the corresponding polishing roller 322 at the same time, greatly improving the efficiency of the rust removal operation.

[0065] When the polished and rust-removed pipe is separated from the arc-shaped polishing sheet 42 and the arc-shaped bracket 41 as the cylinder 31 rotates, the polished pipe is no longer subjected to the squeezing force. At this time, under the restoring force of the spring 3242, the polished pipe is pushed out from the material taking port 301 through the two sets of driving wheels 3234 for further processing.

[0066] As the cylinder 31 continues to rotate, the pipes to be derusted in the feed trough 21 will continuously enter the corresponding material taking port 301, without the need for manual loading and unloading, which greatly reduces the burden on workers. At the same time, the arc-shaped polishing sheet 42 and multiple polishing rollers 322 can continuously derust multiple pipes, greatly improving the efficiency of the rust removal operation.

[0067] In summary, the construction pipe rust removal equipment of the embodiment of the present application can automatically load and unload materials without excessive human intervention, which greatly reduces the burden on workers. At the same time, it can continuously perform rust removal operations on multiple pipes, greatly improving the efficiency and production capacity of the rust removal operation.
