Description

Technical Field

[0001] The present application relates to the technical field of pipe grinding equipment, and in particular to a green, energy-saving and environmentally friendly grinding device for building pipe materials. Background Art

[0002] In construction projects, water supply and drainage often rely on the layout of pipes to construct a network, and pipe layout is a critical step. Common options for water supply and drainage pipes include PVC pipes, PE pipes, and steel pipes coated with an anti-corrosion coating. During the production process of anti-corrosion coated steel pipes, uncoated steel pipes are prone to rust during storage. Before spraying the coating, the steel pipes need to be polished using a grinding device to remove the surface oxide layer and roughen the surface, which can improve the adhesion of the coating to the steel pipe surface.

[0003] With respect to the above-mentioned related technologies, the inventors found that when the surface of the steel pipe is polished, a large amount of smoke and dust will be generated and diffused into the surrounding environment, polluting the surrounding environment. Summary of the Invention

[0004] In order to reduce pollution to the environment and make pipe grinding more environmentally friendly, the present application provides a green, energy-saving and environmentally friendly grinding device for building pipe materials.

[0005] The present application provides a green, energy-saving and environmentally friendly grinding device for building pipe materials, which adopts the following technical solutions:

[0006] A green, energy-saving and environmentally friendly grinding device for building pipe materials, comprising a pipe support and a grinding vehicle, wherein the pipe passes through the grinding vehicle, and the grinding vehicle comprises:

[0007] The vehicle body is hollow and has an inner cavity;

[0008] A rotating drum, rotatably connected to the vehicle body;

[0009] A walking roller is arranged on the rotating drum and includes a roller body;

[0010] A driving mechanism is provided in the vehicle body and is used to drive the drum to rotate;

[0011] A grinding brush, connected to the drum;

[0012] The dust collecting assembly is connected to the vehicle body and is used to collect the smoke and dust generated by grinding;

[0013] The circumferential roller surface of the roller body abuts against the pipe material, and an angle is set between the central axis and the central axis of the pipe material.

[0014] By adopting the technical scheme, the driving mechanism drives the rotating drum to rotate, the walking roller moves along the surface of the pipe, the whole vehicle body can move along the pipe, and the polishing brush also rotates synchronously to polish the surface of the pipe. Only one set of driving mechanism can realize the movement of the vehicle body and the polishing of the polishing brush, driving elements are saved, and the effect of energy saving is achieved. Dust generated by polishing is limited in the vehicle body and collected through the dust collection assembly, dust diffusion during polishing is reduced, pollution to the environment is reduced, and pipe polishing work is more green and environmentally friendly. The pipe length that can be polished by the polishing vehicle is not limited by the setting of the plurality of pipe supports, and the application range of the polishing device is larger.

[0015] Optionally, the walking roller further comprises:

[0016] The guide rod slides along the radial direction of the rotating drum and is arranged on the rotating drum;

[0017] The roller holder is connected to one end of the guide rod close to the pipe;

[0018] The spring is arranged between the roller holder and the rotating drum;

[0019] The roller body is rotationally connected to the roller holder.

[0020] By adopting the technical scheme, the guide rod plays a guiding role on the roller holder, so that the roller body rotationally connected to the roller holder can only move along the radial direction of the rotating drum. The spring pushes the roller holder, so that the roller body is kept in close contact with the surface of the pipe and is not easy to slip off the surface of the pipe.

[0021] Optionally, the guide rod is provided with a synchronous rod, and the polishing vehicle further comprises a synchronous ring rotationally connected to the rotating drum, the synchronous ring is provided with a sliding hole for the synchronous rod to slide, and the sliding hole gradually moves away from the central axis of the synchronous ring.

[0022] By adopting the technical scheme, when the synchronous ring and the guide rod rotate relative to each other, the side wall of the sliding hole will push the synchronous rod, so that the synchronous rod slides along the guide rod, and then the roller body and the side wall of the pipe are in close contact and separated, which is convenient for an operator to install the vehicle body and the pipe.

[0023] Optionally, the circumferential side wall of the synchronous ring is provided with a ratchet, and the vehicle body is provided with a pawl engaged with the ratchet.

[0024] By adopting the technical scheme, when the rotating drum rotates normally, the synchronous rod drives the synchronous ring to rotate, and the ratchet on the synchronous ring can normally pass through the pawl. When the rotating drum reversely rotates, the pawl blocks the rotation of the synchronous ring, and the rotating drum continues to rotate, so that the synchronous rod slides along the sliding hole, the guide rod moves away from the pipe, and the roller body moves synchronously. In this way, the pipe can be conveniently loaded or unloaded between the roller bodies.

[0025] Optionally, the driving mechanism comprises:

[0026] A drive assembly is disposed in the vehicle body;

[0027] The transmission assembly is connected between the driving assembly and the drum.

[0028] By adopting the above technical solution, the driving assembly provides power, which is transmitted to the rotating drum through the transmission assembly, thereby realizing controllable rotation of the rotating drum.

[0029] Optionally, the dust collecting component includes:

[0030] Dust collection pipe, one end of which is connected to the vehicle body;

[0031] A fan is provided on the dust collecting pipe;

[0032] The dust collecting bag is sleeved on the end of the dust collecting pipe away from the vehicle body.

[0033] By adopting the above technical solution, when smoke and dust are generated during the grinding of pipes, the fan can create negative pressure at the inlet of the dust collecting pipe, sucking in the air containing smoke and dust and sending it into the dust collecting bag. The dust collecting bag plays a filtering role, blocking the particulate dust in the air in the bag, and the air flows out through the bag wall.

[0034] Optionally, an insert is provided on the inner wall of the rotating drum, and the grinding brush is plugged into the insert.

[0035] By adopting the above technical solution, the grinding brush and the rotating drum are detachably connected, which is convenient for replacement after the grinding brush is greatly worn out during use, thereby ensuring the grinding quality.

[0036] Optionally, a plurality of the cutting strips are provided along the circumference of the inner wall of the drum.

[0037] By adopting the above technical solution, multiple grinding brushes can intermittently grind the pipe, and the smoke and dust generated on the surface of the pipe can be discharged from the gaps between the grinding brushes.

[0038] Optionally, the pipe support includes:

[0039] gantry, including crossbeams;

[0040] The lifting cylinder is connected to the bottom end of the gantry beam;

[0041] The pipe holding assembly is arranged at the telescopic end of the lifting cylinder.

[0042] By adopting the above technical solution, the lifting cylinder cooperates with the pipe holding assembly to lift the pipe. When the grinding car passes by a certain pipe bracket, the pipe holding assembly releases the pipe, and the lifting cylinder lifts the pipe holding assembly so that the grinding car can pass. After the grinding car passes, the pipe holding assembly is lowered again to suspend the pipe.

[0043] Optionally, the tube holding assembly includes:

[0044] Suction block, connected to lifting cylinder;

[0045] The electromagnet is embedded in the holding block;

[0046] The anti-slip pad is arranged on the side wall where the suction block contacts the pipe.

[0047] By adopting the above technical solution, the magnetic force of the electromagnet is controllable, and the holding state of the pipe holding assembly on the pipe can be quickly changed. After the pipe is held, the pipe contacts the anti-slip pad, which can prevent the pipe from rotating and moving axially, and the walking roller of the grinding machine moves more stably on the pipe.

[0048] In summary, this application includes at least one of the following beneficial technical effects:

[0049] 1. Only one set of driving mechanism is needed to realize the movement of the vehicle body and the grinding of the grinding brush, which saves driving components and has energy-saving effect;

[0050] 2. The dust generated by grinding will be confined to the car body and collected by the dust collection component, which reduces the spread of dust during grinding, reduces pollution to the environment, and makes the pipe grinding work more environmentally friendly;

[0051] 3. By setting up multiple pipe supports, the grinding vehicle can grind pipes without restrictions, making the grinding device more applicable;

[0052] 4. When the synchronizer ring and the guide rod rotate relative to each other, the side wall of the sliding hole will push the synchronizer rod, causing it to slide along the guide rod, thereby achieving the fit and separation between the roller body and the side wall of the pipe, making it easier for operators to install the car body and the pipe;

[0053] 5. When the drum rotates normally, the synchronization rod will drive the synchronization ring to rotate, and the ratchet on the synchronization ring can pass through the pawl normally; when the drum rotates in the opposite direction, the pawl will block the synchronization ring from rotating. When the drum continues to rotate, the synchronization rod will slide along the sliding hole, making the guide rod away from the pipe, and the rollers move synchronously, so that the pipe can be easily loaded or removed between the rollers.

DETAILED DESCRIPTION

[0059] The following is combined with Figure 1 -Attached Figure 4 , further details of this application are given.

[0060] This application proposes a green, energy-saving and environmentally friendly grinding device for building pipe materials. Figure 1 , including a pipe support 1 and a grinding car 2. The pipe support 1 is provided with multiple, used to lift the pipe 100 horizontally, and the grinding car 2 is set outside the pipe 100, which can move along the pipe 100 and grind the surface of the pipe 100.

[0061] Reference Figure 1 and Figure 2 The pipe support 1 includes a gantry 11, a lifting cylinder 12 and a pipe holding assembly 13. The gantry 11 is a door-shaped frame, which is placed on the work site and has a crossbeam on the top. The cylinder body of the lifting cylinder 12 is connected to the bottom end of the crossbeam, and the telescopic end is vertically downward. The lifting cylinder 12 can be an electric cylinder, a pneumatic cylinder or a hydraulic cylinder. In the embodiment of the present application, the lifting cylinder 12 is an electric cylinder. The pipe holding assembly 13 is used to suck the pipe 100, and includes a sucking block 131, an electromagnet 132 and an anti-slip pad 133. The sucking block 131 is U-shaped, with an opening facing downward, and the top end is threadedly connected to the telescopic end of the lifting cylinder 12. Electromagnets 132 are embedded on both sides of the inner wall of the opening of the sucking block 131, which are used to adsorb the pipe 100 by magnetic force. A non-slip pad 133 is bonded to the side of the electromagnet 132 facing the opening of the holding block 131. The non-slip pad 133 is embedded within the opening of the holding block 131, protruding from the inner wall of the opening of the holding block 131. The area of ​​the non-slip pad 133 is larger than that of the electromagnet 132 and completely covers the electromagnet 132. The magnetic force of the electromagnet 132 is controllable, allowing the holding state of the pipe holding assembly 13 on the pipe 100 to be quickly changed. After the pipe 100 is held, the pipe 100 contacts the non-slip pad 133, preventing the pipe 100 from rotating or moving axially, and making the grinding wheel 2 more stable when moving over the pipe 100.

[0062] ReferenceFigure 3 and Figure 4 The grinding car 2 includes a car body 21, a rotating drum 22, a walking roller 23, a driving mechanism 24, a grinding brush 25, a dust collecting assembly 26 and a synchronizer ring 27. The upper part of the car body 21 is a cylinder with a horizontal central axis, and the lower part is a rectangular parallelepiped, and the length of the lower part is shorter than the length of the upper part. Vertical plates are welded on both sides of the lower part of the car body 21, and wheels are rotatably connected to the vertical plates. When the grinding car 2 moves, the wheels roll on the working ground and play a major supporting role for the grinding car 2. If the working site is uneven, a shock absorber can be set between the wheel and the vertical plate to improve the supporting effect of the wheel on the grinding car 2. The upper part of the car body 21 is coaxial with the pipe 100 when moving, and through holes are provided at both ends for the pipe 100 to pass through. The diameter of the through hole is slightly larger than the diameter of the pipe 100.

[0063] The drum 22 is rotatably connected to the vehicle body 21. A bearing is coaxially mounted in the upper portion of the vehicle body 21, and the drum 22 is mounted on the inner race of the bearing. In this embodiment, double-row tapered roller bearings are used, as they can withstand significant radial and axial forces. An annular baffle is integrally formed in the center of the drum 22. The inner bore of the baffle is slightly larger than that of the tubing 100, allowing the tubing 100 to pass through.

[0064] The drive mechanism 24 includes a drive assembly 241 and a transmission assembly 242. The drive assembly 241 is disposed within the rectangular space below the vehicle body 21, and the transmission assembly 242 is connected between the drive assembly 241 and the rotating drum 22. In the embodiment of the present application, the drive assembly 241 is a combination of a servo motor and a reducer, which is bolted to the vehicle body 21 via a T-shaped mounting bracket. The transmission assembly 242 is a combination of a synchronous pulley and a synchronous belt. The servo motor drive shaft and the rotating drum 22 are each provided with a synchronous pulley, and the two synchronous pulleys are connected by a synchronous belt. The operation of the servo motor can drive the rotating drum 22 to rotate forward and reverse.

[0065] The walking roller 23 includes a roller body 231, a roller frame 233, a guide rod 232, and a spring 234. The guide rod 232 is slidably disposed on the wall of the rotating drum 22 along the radial direction of the rotating drum 22, and an anti-slip block is provided at the end away from the pipe 100. Each set of walking rollers 23 is provided with two parallel guide rods 232 along the axial direction of the rotating drum 22. The roller frame 233 is welded to the end of the guide rod 232 facing the pipe 100. The roller body 231 is rotatably connected to the roller frame 233, with the circumferential side wall abutting the side wall of the pipe 100. There is an angle between the central axis and the central axis of the pipe 100. When the rotating drum 22 rotates, the roller body 231 will spirally roll along the circumferential side wall of the pipe 100, thereby driving the entire grinding vehicle 2 to move along the pipe 100. A spring 234 is mounted on the guide rod 232 near the partition, with its ends abutting the inner wall of the drum 22 and the roller frame 233, respectively. This pushes the roller frame 233 toward the pipe 100, ensuring better contact between the roller body 231 and the sidewall of the pipe 100. A synchronization rod 2321 is welded perpendicularly to the guide rod 232 away from the partition. In this embodiment, eight groups of travel rollers 23 are evenly spaced along the axial direction of the drum 22.

[0066] The synchronizer ring 27 is rotatably connected to the end of the rotating drum 22 that connects to the travel roller 23. The synchronizer ring 27 is provided with an axially extending sliding hole 271. The sliding hole 271 is a waisted arc-shaped hole, and the distance between the sliding hole 271 and the central axis of the synchronizer ring 27 gradually increases along the circumference of the synchronizer ring 27. A synchronizer rod 2321 slides through the sliding hole 271, with a diameter slightly smaller than the width of the sliding hole 271. When the synchronizer ring 27 and the guide rod 232 rotate relative to each other, the sidewall of the sliding hole 271 pushes on the synchronizer rod 2321, causing it to slide along the guide rod 232, thereby achieving contact and separation between the roller body 231 and the sidewall of the pipe 100, facilitating the operator's installation of the vehicle body 21 and the pipe 100. Ratchet teeth 272 are integrally formed on the circumferential sidewalls of the synchronizer ring 27.

[0067] A pawl 28 is provided on the inner wall of the upper portion of the body 21. This pawl 28 engages with the ratchet teeth 272, limiting the synchronizing ring 27 to single-direction rotation. In this embodiment, three pawls 28 are provided. When the synchronizing ring 27 rotates, powered by a synchronizing rod 2321, the rotating drum 22 drives the synchronizing rod 2321. When the rotating drum 22 reverses, the pawl 28 blocks the synchronizing ring 27, causing relative rotation between the rotating drum 22 and the synchronizing ring 27. The synchronizing rod 2321 slides along the slide hole 271 and away from the central axis of the synchronizing ring 27, causing the rollers 231 to move away from each other, facilitating the loading and unloading of the tubular 100 between the rollers 231.

[0068] A strip 221 is installed on the inner wall of the end of the rotating drum 22 away from the synchronizing ring 27. The strip 221 has a T-shaped longitudinal cross-section and extends axially along the rotating drum 22. A grinding brush 25 comprises a handle and a brush head. The handle has a slot for the strip 221. The handle is plugged into the strip 221 and removably connected to it via bolts. The brush head abuts the circumferential outer wall of the pipe 100. In this embodiment, six groups of grinding brushes 25 and strips 221 are arranged at intervals along the circumference of the rotating drum 22. Multiple grinding brushes 25 allow for intermittent grinding of the pipe 100, allowing smoke and dust generated on the pipe 100 surface to be discharged through the gaps between the grinding brushes 25.

[0069] The dust collecting assembly 26 includes a dust collecting pipe 261, a fan 262 and a dust collecting bag 263. A dust collecting pipe 261 is welded to the bottom of the upper end of the vehicle body 21 away from the synchronization ring 27, and the dust collecting pipe 261 is vertically downward. The fan 262 is arranged in the dust collecting pipe 261, and the air outlet direction is away from the rotating drum 22. The opening of the dust collecting bag 263 is sleeved on the lower end of the dust collecting pipe 261, and the dust collecting pipe 261 is detachably connected by a clamp or a rope. When dust is generated by polishing the pipe 100, the fan 262 can create a negative pressure at the entrance of the dust collecting pipe 261, sucking in the air containing dust and sending it into the dust collecting bag 263. The dust collecting bag 263 plays a filtering role, blocking the particulate dust in the air in the bag, and the air flows out through the bag wall. The outside air enters through the gap between the vehicle body 21 and the pipe 100, so that the dust in the vehicle body 21 is not easy to fly out of the vehicle body 21.

[0070] The implementation principle of the embodiment of the present application is as follows: first, multiple pipe supports 1 are used to lift the pipe 100 horizontally, and the height of the central axis is aligned with the central axis of the rotating drum 22; one end of the grinding car 2 is provided with a synchronization ring 27 as the entrance of the pipe 100, and the driving component 241 is started to reverse the rotating drum 22, and each walking roller 23 is opened; after the pipe 100 enters the grinding car 2, the driving component 241 is started, the rotating drum 22 rotates, the walking rollers 23 are retracted, the roller body 231 abuts and clamps the pipe 100, and the roller body 231 moves along a spiral trajectory on the surface of the pipe 100, thereby driving the grinding car 2 to move, and at the same time, the grinding brush 25 rotates to grind the side wall of the pipe 100; when the grinding car 2 passes by a certain pipe support 1, the electromagnet 132 of the pipe support 1 is de-energized, the lifting cylinder 12 is retracted, and the pipe 100 is suspended by other pipe supports 1. After the grinding car 2 passes, the pipe 100 can be re-adsorbed.
