Description

Technical Field

[0001] This utility model relates to the field of pipe processing equipment technology, and more specifically, to a dustproof and waterproof pipe processing equipment. Background Technology

[0002] Pipe processing machinery, such as stationary pipe cutting machines and beveling machines, is a key piece of equipment in fields such as petrochemicals, municipal engineering, and shipbuilding.

[0003] However, existing pipe-making equipment may be used in complex environments, especially in harsh conditions such as mines, tunnels, outdoor operations during the rainy season, or operations with water. The equipment also generates a large amount of dust during operation, which pollutes the working environment. The core components of the equipment, such as the drive motor and transmission system, are usually directly exposed to the processing environment and cannot cope with diffuse dust, splashed liquids, and pollutants. This can easily lead to wear of transmission components and short circuits in the electrical system, resulting in extremely low equipment lifespan and reliability. Utility Model Content

A transmission unit, with its two ends respectively disposed in the processing cabinet and the transition box, and a cutting blade mounted on the transmission unit; A drive unit is installed inside the isolation box and connected to the transmission unit to drive the transmission unit to rotate the cutting blade. A connecting part is disposed between the transmission part and the drive part to complete the rigid connection between the transmission part and the drive part and to close the bottom of the isolation box; A lifting unit, which is installed inside the isolation box, is used to control the drive unit to move vertically inside the isolation box; Cooling unit, which is fixed inside the processing cabinet; The collection unit is installed inside the processing cabinet and movably sleeved outside the cutting blade for collecting cutting fluid and dust.

[0006] Furthermore, the drive unit includes a support frame disposed inside the isolation box, a drive motor mounted on the support frame, a transmission shaft rotatably mounted on the support frame, two transmission wheels respectively connected to the upper end of the transmission shaft and the output end of the drive motor, a tension wheel movably mounted on the support frame, and a transmission belt sleeved on the outside of the tension wheel and the two transmission wheels.

[0007] Furthermore, the transmission unit includes a transmission box disposed in the transition box, a transmission sleeve disposed in the processing cabinet and connected to the transmission box, a first bevel gear rotatably mounted in the transmission box and fixed to the lower end of the transmission shaft, a control rod rotatably mounted in the transmission sleeve, and a second bevel gear fixed to one end of the control rod and meshing with the first bevel gear. The cutting blade is mounted on the other end of the control lever.

[0008] Furthermore, the connecting part includes two reserved slots opened on the lower surface of the isolation box, a connecting plate fixed on the transmission sleeve, one end of which is fixedly connected to the lower surface of the support frame, and the other end of which passes through the two reserved slots respectively and is fixed to the connecting plate and the transmission box respectively. Two connecting pipes have one end connected to the two reserved slots respectively, and the other end of which is fixed to the two corrugated sealing sleeves at the upper end of the connecting plate and the transmission box respectively. One of the connecting pipes is movably sleeved outside the drive shaft, and the two corrugated sealing sleeves are respectively movably sleeved outside the two connecting pipes.

[0009] Furthermore, the lifting unit includes two electric push rods symmetrically fixed inside the isolation box, two connecting frames fixed to the telescopic ends of the two electric push rods and both fixed to the support frame, several guide rails fixed in a rectangular row on the inner wall of the isolation box, several roller groups mounted in a rectangular row on the support frame and slidably connected to the several guide rails, several guide rods with one end fixed to the lower surface of the isolation box and the other end fixed to the inner wall of the transition box, several guide grooves symmetrically opened on both sides of the transmission box and corresponding to the several guide rods.

[0010] Furthermore, the cooling unit includes a liquid storage tank fixed to the bottom of the processing cabinet, a liquid pump installed at the top of the processing cabinet, a liquid delivery pipe with one end connected to the liquid pump inlet and the other end connected to the lower end of the liquid storage tank, and a liquid injection hose with one end connected to the liquid pump outlet.

[0011] Furthermore, the collection unit includes an upper shield fixed to one end of the transmission sleeve and movably sleeved outside the cutting blade, a lower shield fixed inside the processing cabinet and movably sleeved below the upper shield, a sedimentation tank connected to the lower shield via a pipe, a cyclone separator connected to the upper end of the sedimentation tank, and a material placement trough opened on the upper shield and the lower shield.

[0012] Compared with the prior art, the embodiments of this utility model have the following beneficial effects: This dustproof and waterproof pipe machine device, through the cooperation of the isolation box and the connecting part, places the drive part and the lifting part in the isolation box, keeping them in a constant clean and dry environment. This fundamentally eliminates faults such as motor burnout and electrical short circuits caused by dust and moisture intrusion, greatly improving the reliability and service life of the structure. Furthermore, when the lifting part controls the drive part to drive the transmission part to move up and down synchronously, the corrugated sealing sleeve in the connecting part cooperates with the connecting pipe to effectively seal the openings caused by the lifting movement while transmitting vertical power from the drive part to the transmission part. This achieves effective dynamic sealing and prevents dust and moisture from entering the isolation box. The dustproof and waterproof pipe cutting machine's collection section, through the cooperation of an upper and lower shield, forms a movable local suction cavity at the cutting point of the cutting blade. This effectively captures the dust generated during pipe cutting, as well as the cutting fluid used for dust reduction and cooling. Combined with a collection mechanism consisting of a sedimentation tank and a cyclone separator, and with the assistance of an external vacuum pump and collection box, it effectively classifies the gas, liquid, and solid three-phase mixture, preventing dust dispersion and cutting fluid splashing during operation. This improves the working environment and eliminates the risk of dust pollution and the harm to personnel caused by cutting fluid splashing. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] like Figure 1-6 As shown, a dustproof and waterproof pipe cleaning device includes: a processing cabinet 1, a transition box 2 connected to the side wall of the processing cabinet 1, an isolation box 3 fixedly connected to the upper end of the processing cabinet 1 and the transition box 2, a maintenance door 4 hinged to the top of the isolation box 3, and a sealing ring 5 fixed to the inner wall of the maintenance door 4 that abuts against the isolation box 3. The transmission part 6 has two ends respectively disposed in the processing cabinet 1 and the transition box 2, and a cutting blade 7 is installed on the transmission part 6; The drive unit 8 is installed inside the isolation box 3 and connected to the transmission unit 6, and is used to drive the transmission unit 6 to drive the cutting blade 7 to rotate. Connecting part 9, which is disposed between the transmission part 6 and the driving part 8, is used to complete the rigid connection between the transmission part 6 and the driving part 8 and to seal the bottom of the isolation box 3; A lifting unit 10 is installed inside the isolation box 3 and is used to control the drive unit 8 to move vertically inside the isolation box 3. Cooling unit 11, the cooling unit 11 is fixed inside the processing cabinet 1; Collection unit 12, which is installed inside the processing cabinet 1 and movably sleeved on the outside of the cutting blade 7, is used to collect cutting fluid and dust; In use, the operator activates the drive unit 8 located inside the isolation box 3 via an external control system. The drive motor 14, through two transmission belts 18 and transmission wheels 16, drives the transmission shaft 15 to rotate. The rotational power is transmitted to the transmission unit 6 through the connecting part 9. Under the meshing transmission of the first bevel gear 21 and the second bevel gear 23, the direction of rotational motion is changed from vertical to horizontal, thereby driving the control lever 22 and the cutting blade 7 at its end to rotate at high speed. At the same time, the lifting unit 10 operates, and the two electric push rods 28 are activated, driving the entire drive unit 8 to move vertically through the support frame 13. The transmission unit 6 is rigidly connected to the support frame 13 through the connecting part 9, so that the transmission unit 6 also moves vertically and stably in sync. Several guide rails 30 and several guide rods 32 ensure the motion accuracy of the drive unit 8 and the transmission unit 6 until the cutting blade 7 contacts the pipe and the cutting operation begins. The corrugated sealing sleeve 27 in the connecting part 9 can freely extend and retract with the operation of the lifting unit 10, always effectively sealing the opening at the bottom of the isolation box 3, ensuring stable power transmission while ensuring the sealing of the isolation box 3, so that the drive unit 8 inside and the lifting unit 10 can move vertically and stably. The lowering section 10 operates in a clean, dry environment, unaffected by harsh external conditions. This allows the device to operate stably in extreme environments with high dust, high humidity, and even water splashes, effectively extending its lifespan. Simultaneously, a heat pipe heat exchanger can be installed in the isolation box 3 to prevent damage to the drive section 8 and the lowering section 10 due to high temperatures during operation. Furthermore, during cutting, the cooling section 11 operates, with the liquid pump 35 pumping cutting fluid from the storage tank 34 through the injection hose 37, precisely spraying it onto the cutting point to cool the cutting tool, lubricate it, and suppress dust. Simultaneously, the collection unit 12 starts up, the upper shield 38 moves synchronously with the transmission unit 6, and the lower shield 39 is fixed. The two form a moving, relatively closed cavity to shield the processing point from cutting fluid, dust and chips generated by the cutting work. The external vacuum pump starts working and generates negative pressure in the closed cavity. Air containing pollutants is instantly sucked in and first enters the sedimentation tank 40 for separation through the pipeline. It is then further separated by the cyclone separator 41, so that there is no dust or cutting fluid splashing at the processing site, ensuring a clean working environment.

[0018] Optionally, the drive unit 8 includes a support frame 13 disposed in the isolation box 3, a drive motor 14 mounted on the support frame 13, a transmission shaft 15 rotatably mounted on the support frame 13, two transmission wheels 16 respectively connected to the upper end of the transmission shaft 15 and the output end of the drive motor 14, a tension wheel 17 movably mounted on the support frame 13, and a transmission belt 18 meshing with the tension wheel 17 and the two transmission wheels 16 outside; In use, the drive motor 14 transmits power to the drive shaft 15 through the belt drive structure consisting of the drive wheel 16, the drive belt 18 and the tension wheel 17 to control the operation of the transmission part 6. The belt drive can buffer and absorb impact loads, has low operating noise, and provides a certain overload protection for the motor. The tension wheel 17 is used to maintain the tension of the drive belt 18 to ensure smooth power transmission without slippage.

[0019] Optionally, the transmission unit 6 includes a transmission box 19 disposed in the transition box 2, a transmission sleeve 20 disposed in the processing cabinet 1 and connected to the transmission box 19, a first bevel gear 21 rotatably mounted in the transmission box 19 and fixed to the lower end of the transmission shaft 15, a control rod 22 rotatably mounted in the transmission sleeve 20, and a second bevel gear 23 fixed to one end of the control rod 22 and meshing with the first bevel gear 21. The cutting blade 7 is mounted on the other end of the control lever 22; In use, the drive unit 8 drives the transmission shaft 15 to rotate, and the transmission shaft 15 drives the first bevel gear 21 to rotate synchronously. The first bevel gear 21 meshes with the transmission shaft 15, changing the power direction from vertical to horizontal, thereby driving the control lever 22 and the cutting blade 7 to rotate and perform pipe cutting operations. The transmission box 19 and the transmission sleeve 20 provide a solid support for the gears and the control lever 22, ensuring transmission accuracy and stability, and reducing vibration when the cutting blade 7 rotates at high speed.

[0020] Optionally, the connecting part 9 includes two reserved slots 24 formed on the lower surface of the isolation box 3, a connecting plate 25 fixed on the transmission sleeve 20, one end fixedly connected to the lower surface of the support frame 13, and the other end passing through the two reserved slots 24 respectively and fixed to the connecting plate 25 and the transmission box 19 respectively. Two connecting pipes 26 have one end connected to the two reserved slots 24 respectively, and the other end fixed to the two corrugated sealing sleeves 27 at the upper end of the connecting plate 25 and the transmission box 19 respectively. One of the connecting pipes 26 is movably sleeved outside the drive shaft 15, and the two corrugated sealing sleeves 27 are respectively movably sleeved outside the two connecting pipes 26; Two connecting pipes 26 complete the rigid connection between the support frame 13, the transmission box 19, and the connecting plate 25. One of them serves as the movable channel for the transmission shaft 15, ensuring the stable connection between the transmission part 6 and the drive part 8. The two ends of the two corrugated sealing sleeves 27 are fixed to the isolation box 3 and the movable transmission part 6 below, respectively. When the lifting part 10 drives the support frame 13 and the transmission part 6 to move, the two connecting pipes 26 move in the two reserved slots 24, and the corrugated sealing sleeves 27 extend and retract accordingly. However, they always effectively seal the gaps in the reserved slots 24, preventing external dust and moisture from entering the isolation box 3. This ensures that the drive part 8 and the lifting part 10 inside the isolation box 3 are always in a dry and clean working environment, guaranteeing the service life of the equipment.

[0021] Optionally, the lifting unit 10 includes two electric push rods 28 symmetrically fixed inside the isolation box 3, two connecting frames 29 fixed to the telescopic ends of the two electric push rods 28 and both fixed to the support frame 13, several guide rails 30 fixed in a rectangular row on the inner wall of the isolation box 3, several roller groups 31 mounted in a rectangular row on the support frame 13 and slidably connected to the several guide rails 30, several guide rods 32 with one end fixed to the lower surface of the isolation box 3 and the other end fixed to the inner wall of the transition box 2, and several guide grooves 33 symmetrically opened on both sides of the transmission box 19 and corresponding to the several guide rods 32 respectively. During cutting operations or maintenance of the cutting blade 7, the two electric push rods 28 work synchronously. With the cooperation of several guide rails 30 and roller group 31, they drive the support frame 13 to move stably vertically in the isolation box 3. Since the transmission part 6 is rigidly connected to the support frame 13 through the connecting part 9, and the movement of the transition box 2 in the transmission part 6 is guided and restricted by several guide rods 32, the transmission part 6 drives the cutting blade 7 to move synchronously, stably and accurately vertically to perform pipe cutting operations and ensure processing accuracy.

[0022] Optionally, the cooling unit 11 includes a liquid storage tank 34 fixed to the bottom of the processing cabinet 1, a liquid pump 35 installed at the top of the processing cabinet 1, a liquid delivery pipe 36 with one end connected to the liquid inlet of the liquid pump 35 and the other end connected to the lower end of the liquid storage tank 34, and a liquid injection hose 37 with one end connected to the liquid outlet of the liquid pump 35. While the pipe is being cut, the liquid pump 35 draws cutting fluid from the storage tank 34 and delivers it to the cutting point through the delivery pipe 36 and the injection hose 37. The fluid is then sprayed directly onto the contact area between the cutting blade 7 and the pipe fitting, thereby cooling and lubricating the cutting process. This reduces the cutting temperature, decreases the wear of the cutting blade 7, and improves the lifespan and cutting quality of the cutting blade 7. Furthermore, the cutting fluid can wet the fine dust generated during cutting, effectively suppressing dust from flying.

[0023] Optionally, the collection unit 12 includes an upper shield 38 fixed to one end of the transmission sleeve 20 and movably sleeved outside the cutting blade 7, a lower shield 39 fixed inside the processing cabinet 1 and movably sleeved below the upper shield 38, a sedimentation tank 40 connected to the lower shield 39 via a pipe, a cyclone separator 41 connected to the upper end of the sedimentation tank 40, and a material placement trough opened on the upper shield 38 and the lower shield 39. The upper and lower ends of the cyclone separator 41 are connected to an external vacuum pump and an external collection box through pipes; With the cooperation of the upper shield 38 and the lower shield 39, a relatively closed cavity is formed at the cutting position of the cutting blade 7 during pipe cutting. As the external vacuum pump draws in, a negative pressure is generated in the sedimentation tank 40 and the cavity, which confines the mixture containing chips, dust and cutting fluid within the upper shield 38 and the lower shield 39 and draws it into the sedimentation tank 40. The flow rate of the mixture decreases, and the heavier chips and some dust settle to the bottom of the tank under gravity. The air containing fine dust and liquid mist enters the cyclone separator 41, where it rotates at high speed. The dust and liquid mist are thrown against the wall and collected by centrifugal force. The purified air is discharged from the top, effectively treating the dust generated during the cutting process and the cutting fluid used for cooling and dust suppression, thereby avoiding dust and cutting fluid splashing, maintaining the processing environment, and achieving good dustproof and waterproof effects.

[0024] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
