DETAILED DESCRIPTION

[0025] 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.

[0026] The construction steel pipe cleaning equipment of an embodiment of the present application is described below with reference to the accompanying drawings.

[0027] like Figure 1-Figure 6 As shown, the construction steel pipe cleaning equipment of the embodiment of the present application may include: a box body 1, a conveying mechanism 2, a plurality of supporting mechanisms 3 and a processing mechanism 4.

[0028] The box body 1 contains liquid.

[0029] It should be noted that the liquid described in this embodiment is water or concrete corrosive liquid, which can loosen the concrete on the surface of the construction steel pipe, thereby facilitating the removal of the concrete.

[0030] As a possible situation, in order to ensure that the construction steel pipe is immersed in the liquid during cleaning, a liquid level sensor (not shown in the figure) can be installed on the inner wall of the box body 1. The liquid level sensor is connected to an external control device to monitor the liquid level in the box body 1, thereby ensuring that the volume of the liquid in the box body 1 is at a preset amount.

[0031] The conveying mechanism 2 is installed outside the box body 1 . The conveying mechanism 2 is used to transport the construction steel pipes to be cleaned. A sinking part 51 is provided on the conveying mechanism 2 .

[0032] A plurality of support mechanisms 3 are respectively arranged on the conveying mechanism 2 , one support mechanism 3 is located inside the sinking part 51 , the support mechanism 3 abuts against the outer wall of the building steel pipe to be cleaned, and the support mechanism 3 is used to limit the building steel pipe to be cleaned.

[0033] The processing mechanism 4 includes a transverse driving module 41, a longitudinal driving assembly 42, a rotation driving assembly 43 and two sets of scraping assemblies 44, wherein:

[0034] The transverse driving module 41 is arranged on the box body 1, and is used to drive the longitudinal driving assembly 42, the rotating driving assembly 43 and the two sets of scraping assemblies 44 to move along the moving direction of the conveying mechanism 2 and the direction of the building steel pipe to be cleaned;

[0035] The longitudinal drive assembly 42 is connected to the transverse drive module 41, and the longitudinal drive assembly 42 is used to push the rotary drive assembly 43 and the two sets of scraping assemblies 44 to contact the outer wall of the building steel pipe to be cleaned;

[0036] The rotary drive assembly 43 is installed at the bottom of the longitudinal drive assembly 42, and the outer wall of the rotary drive assembly 43 abuts against the outer wall of the building steel pipe to be cleaned. The rotary drive assembly 43 is used to drive the building steel pipe to be cleaned to rotate;

[0037] Two groups of scraping assemblies 44 are respectively arranged on both sides of the rotating driving assembly 43. The scraping assemblies 44 are located above the sinking part 51. The scraping assemblies 44 extend into the liquid. The scraping assemblies 44 are used to clean the concrete attached to the outer wall of the construction steel pipe.

[0038] In the embodiment of the present application, a control device (not shown in the figure) is provided on the box body 1, and the conveying mechanism 2 and the processing mechanism 4 are respectively connected to the control device.

[0039] Specifically, relevant technicians (such as workers) use the equipment to clean concrete attached to construction steel pipes. First, the equipment is operated, and the conveying mechanism 2 and the processing mechanism 4 start to operate.

[0040] A worker places a construction steel pipe to be cleaned on a supporting mechanism 3, and the conveying mechanism 2 drives the supporting mechanism 3 and the construction steel pipe to be cleaned to move at a uniform speed. When the construction steel pipe moves to just below the initial position of the processing mechanism 4 (this working condition can be obtained through a position sensor), the transverse driving module 41 drives the longitudinal driving component 42, the rotating driving component 43 and two groups of scraping components 44 to move. The movement speed of the scraping component 44 is equal to that of the construction steel pipe, and the two are relatively stationary.

[0041] At the same time, the longitudinal drive component 42 pushes the rotary drive component 43 and the two groups of scraping components 44 to contact the outer wall of the construction steel pipe to be cleaned (this working condition can be obtained through a pressure sensor), and the construction steel pipe is immersed in the liquid and forms a sinking portion 51 on the conveying mechanism 2. The rotary drive component 43 drives the construction steel pipe to rotate at a uniform speed, and the scraping component 44 cleans the concrete attached to the outer wall of the construction steel pipe. The above cleaning process is carried out in the liquid, which can prevent dust from floating randomly and ensure that the environment of the working area is not polluted.

[0042] Under the action of the transverse driving module 41, the scraping component 44 can clean the outer wall of the entire building steel pipe. During the cleaning process, concrete particles accumulate at the sinking part 51. Since the position of the sinking part 51 changes with the position of the building steel pipe, the concrete particles enter the interior of the box body 1. When the transverse driving module 41 moves to the end position, the longitudinal driving component 42 is reset, the rotation driving component 43 is paused, the position of the support mechanism 3 and the building steel pipe rises, the curvature of the sinking part 51 decreases and moves to the middle part of the box body 1. In the above process, the concrete particles on the sinking part 51 can be transferred to the interior of the box body 1, thereby avoiding the need for subsequent manual cleaning and ensuring the continuous progress of the cleaning process.

[0043] When the construction steel pipe moves to the other end of the box 1, the support mechanism 3 flips over, and the construction steel pipe completes autonomous unloading under the action of gravity. The worker places the next construction steel pipe to be cleaned on the next support mechanism 3 and repeats the above steps to complete the cleaning of the construction steel pipe.

[0044] In the embodiments of the present application, the loading, cleaning and unloading processes of the construction steel pipe do not interfere with each other and can be operated independently, thereby improving the cleaning efficiency of the construction steel pipe.

[0045] In one embodiment of the present application, Figure 1 and Figure 3 As shown, the conveying mechanism 2 includes two first reversing roller shafts 21 , two second reversing roller shafts 22 and a transmission member 23 .

[0046] The two first reversing roller shafts 21 and the two second reversing roller shafts 22 are respectively connected to the box body 1 , and the transmission member 23 is wound around the outer sides of the two first reversing roller shafts 21 and the two second reversing roller shafts 22 .

[0047] It should be noted that a motor is also provided on the outer side of the box body 1 described in this embodiment, and the output shaft of the motor is connected to one end of a second reversing roller shaft 22, thereby driving the transmission member 23 to rotate counterclockwise at a uniform speed.

[0048] As a possible situation, in order to extend the service life of the transmission member 23, the transmission member 23 may be a metal chain rail.

[0049] In one embodiment of the present application, Figure 1 and Figure 4 As shown, the supporting mechanism 3 includes two fixing rods 31 , a bracket 32 ​​and a plurality of rollers 34 .

[0050] Among them, two fixing rods 31 are respectively arranged on the transmission member 23, and the bracket 32 ​​is arranged in an X-shaped structure. The bracket 32 ​​is connected to the two fixing rods 31, and a plurality of through slots 33 are opened on the bracket 32, and a plurality of rollers 34 are respectively installed inside the corresponding through slots 33.

[0051] Specifically, the construction steel pipe to be cleaned is placed on the bracket 32, the bottom of the rotating drive component 43 is in contact with the outer wall of the construction steel pipe, the rotating drive component 43 drives the construction steel pipe to rotate, and the roller 34 rotates along with the rotation of the construction steel pipe, thereby limiting the construction steel pipe and ensuring the reliability of the cleaning of the construction steel pipe concrete.

[0052] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the transverse driving module 41 includes two first electric slides 411 , two connecting plates 412 and a second electric slide 413 .

[0053] The two first electric slides 411 are symmetrically arranged on both sides of the box body 1 , one end of the two connecting plates 412 is respectively connected to the sliders of the corresponding first electric slides 411 , and the second electric slide 413 is connected to the other ends of the two connecting plates 412 .

[0054] It should be noted that the specific structures of the first electric slide 411 and the second electric slide 413 described in this embodiment have been disclosed in the prior art, so they will not be described in detail here.

[0055] In one embodiment of the present application, Figure 1 and Figure 5 As shown, the longitudinal drive assembly 42 includes a connecting slot 421 , a mounting frame 422 and an electric telescopic rod 423 .

[0056] Among them, the connecting groove 421 is connected to the slider of the second electric slide 413, the mounting frame 422 is sleeved on the outside of the connecting groove 421, the mounting frame 422 is slidingly connected to the connecting groove 421, and the electric telescopic rod 423 is installed between the connecting groove 421 and the mounting frame 422.

[0057] In one embodiment of the present application, Figure 1 and Figure 2 As shown, the rotation driving assembly 43 includes two supporting plates 431 , a connecting rod 432 , a driving gear 433 , a driving motor 434 , two rubber wheels 435 and a driven gear 436 .

[0058] Among them, one end of the two support plates 431 is connected to the mounting frame 422, the two ends of the connecting rod 432 are rotatably connected to the two support plates 431, the driving gear 433 is set on the connecting rod 432, the driving motor 434 is installed on a support plate 431, one end of the connecting rod 432 passes through a support plate 431, one end of the connecting rod 432 is connected to the output shaft of the driving motor 434, the two rubber wheels 435 are respectively rotatably connected to the two support plates 431, the driven gear 436 is set between the two rubber wheels 435, and the driving gear 433 is meshed with the driven gear 436.

[0059] Specifically, during the operation of the processing mechanism 4, the first electric slide 411 can drive the second electric slide 413 to move at a constant speed along the movement direction of the conveying mechanism 2 through the connecting plate 412, and the second electric slide 413 can connect the groove 421 and move at a constant speed along the direction of placement of the construction steel pipe.

[0060] The electric telescopic rod 423 is in operation, and the electric telescopic rod 423 changes the distance between the connecting groove 421 and the mounting bracket 422 , so that the bottom of the rotary drive assembly 43 abuts against the outer wall of the building steel pipe.

[0061] During the operation of the rotating drive component 43, the driving motor 434 drives the driving gear 433 to rotate, the driving gear 433 is meshed and connected with the driven gear 436, the two rubber wheels 435 rotate, the rubber wheels 435 drive the construction steel pipe to rotate at a uniform speed, and the scraping component 44 cleans the concrete on the surface of the construction steel pipe.

[0062] It should be noted that when the bottom of the rotating drive assembly 43 contacts the outer wall of the construction steel pipe, there is a certain force between the rubber wheel 435 and the construction steel pipe (this working condition can be obtained through a pressure sensor). This force can be determined according to actual conditions, so that the rubber wheel 435 and the construction steel pipe can rotate synchronously.

[0063] In one embodiment of the present application, Figure 1 and Figure 6 As shown, the scraping assembly 44 includes a fixing member 441 , a scraper 442 and a rubber block 443 .

[0064] One end of the fixing member 441 is connected to the support plate 431 , the scraper 442 is pivotally connected to the fixing member 441 , and the rubber block 443 is embedded between the scraper 442 and the fixing member 441 .

[0065] As a possible situation, in order to ensure that the scraper 442 fits the outer wall of the construction steel pipe, a pressure sensor (not shown in the figure) can be embedded inside the rubber block 443. When the pressure sensor detects that the scraper 442 squeezes the rubber block 443 to reach a preset pressure value, the longitudinal drive assembly 42 stops running.

[0066] It is understandable that the rubber block 443 can also play a buffering role. When the concrete on the outer wall of the construction steel pipe is harder, the scraper 442 can squeeze the rubber block 443, so that the scraper 442 is lifted up, thereby passing over the hard concrete block.

[0067] In one embodiment of the present application, Figure 3 As shown, the box body 1 is provided with a plurality of support plates 61, and a rod body 62 is rotatably connected to the support plate 61. A first gear 63 is provided at one end of the rod body 62, and toothed belts 64 are respectively provided on both sides of the transmission member 23. The first gear 63 is meshedly connected with the toothed belt 64.

[0068] It can be understood that the meshing connection of the toothed belt 64 of the first gear 63 can ensure that the transmission member 23 above the box body 1 is drooped into the interior of the box body 1 in an arc-shaped structure, thereby ensuring that the construction steel pipe is immersed in the liquid during the cleaning process.

[0069] In summary, in the construction steel pipe cleaning equipment of the embodiment of the present application, the processing mechanism presses the steel pipe to be cleaned and immerses it into the interior of the liquid, and the cleaning process is carried out in the liquid, which can prevent dust from floating around and ensure that the environment of the working area is not polluted. During the cleaning process, the conveying mechanism is continuously immersed in and out of the liquid, and the concrete particles that fall on the conveying mechanism are carried away by the liquid to avoid accumulation, thereby reducing the workload of workers and ensuring the normal progress of the cleaning process.
