Description

Technical Field

[0001] This utility model relates to a sandblasting device, specifically a sandblasting device for valve surface treatment, and belongs to the technical field of sandblasting devices. Background Technology

[0002] A valve is a mechanical device used to control the flow of fluid. After the valve is cast, there will be impurities such as oxide scale and residual molding sand on the surface. A sandblasting machine uses high-speed jets of sand to impact the valve surface, which can efficiently remove these impurities and make the valve surface clean, providing a good foundation for subsequent surface treatment processes. The sand delivery pipe of the sandblasting machine is relatively long. When the equipment is idle or needs to be transported, the sand delivery pipe is usually wrapped around the outer shell of the sandblasting machine for easy storage and management.

[0003] However, the simple winding method does not use a special fastening component to lock the position of the sand conveying pipe, and cannot provide sufficient fastening force for the sand conveying pipe. When the sandblasting machine shakes or tilts, the sand conveying pipe is prone to sliding or shifting downward under the action of gravity, thereby destroying the stability of the winding. In particular, during the transportation of the sandblasting machine, it is necessary to use ropes to fix the sand conveying pipe that has been wound on the sandblasting machine shell. The operation of fixing with ropes is relatively cumbersome, and the fixing force of the ropes is relatively weak. During transportation, when the sandblasting machine shakes, the ropes are prone to loosening, which will cause the sand conveying pipe to fall off. Utility Model Content

[0004] The purpose of this utility model is to provide a sandblasting device for valve surface treatment in order to solve the above problems. By setting a winding structure on the main body of the sandblasting machine to wind the sand conveying pipe around the outside of the fixing ring, the sand conveying pipe can be stored neatly and orderly, which not only saves space and facilitates the transportation of the sandblasting machine, but also makes it easier for operators to use and organize the sand conveying pipe.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: a sandblasting device for valve surface treatment, comprising a sandblasting machine body, a sand conveying pipe installed at the sand outlet of the sandblasting machine body, a winding structure installed on the sandblasting machine body, the winding structure including a fixing ring, a fixing ring fixedly connected to the outside of the sandblasting machine body, the sand conveying pipe wound around the outside of the fixing ring, two mounting blocks fixedly connected to the bottom end of the fixing ring, a rotating shaft fixedly connected to the mounting blocks, a limiting block rotatably connected to the rotating shaft, two protrusions fixedly connected to the top end of the fixing ring, the limiting block inserting into the protrusions, a locking block slidably connected inside the protrusions, a locking groove opened on the limiting block, the end of the locking block engaging with the locking groove, a spray gun installed at the end of the sand conveying pipe, a fixing block installed on the sandblasting machine body, the spray gun slidably connected to the fixing block, and a limiting structure installed on the fixing block.

[0006] Preferably, the limiting block has an "L" shaped structure, and the end of the locking block has a beveled structure.

[0007] Preferably, a torsion spring is sleeved on the rotating shaft, one end of the torsion spring is fixedly connected to the rotating shaft, and the other end of the torsion spring is fixedly connected to the limiting block.

[0008] Preferably, a connecting block is fixedly connected to the card block, a first guide rod is fixedly connected inside the protrusion, the connecting block is slidably connected to the first guide rod, and a spring is sleeved on the outside of the first guide rod, with the two ends of the spring being fixedly connected to the protrusion and the connecting block, respectively.

[0009] Preferably, the fixing ring has a guide groove, and the sand conveying pipe is slidably connected to the guide groove.

[0010] Preferably, the fixed block has a U-shaped cross-section, the limiting structure includes a stop block, the stop block is slidably connected to the fixed block, and the stop block abuts against the spray gun.

[0014] The beneficial effects of this utility model are as follows: A fixing ring is fixedly connected to the outside of the main body of the sandblasting machine, and the sand conveying pipe is wound around the outside of the fixing ring. By setting a winding structure on the main body of the sandblasting machine to wind the sand conveying pipe around the outside of the fixing ring, the sand conveying pipe can be stored neatly and orderly, which not only saves space and facilitates the transportation of the sandblasting machine, but also makes it easier for operators to use and organize the sand conveying pipe, thus improving work efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-5 As shown, a sandblasting device for valve surface treatment includes a sandblasting machine body 1. A sand conveying pipe 2 is installed at the sand outlet of the sandblasting machine body 1. A winding structure 3 is installed on the sandblasting machine body 1. The winding structure 3 includes a fixing ring 301. The fixing ring 301 is fixedly connected to the outside of the sandblasting machine body 1. The sand conveying pipe 2 is wound around the outside of the fixing ring 301. Two mounting blocks 302 are fixedly connected to the bottom end of the fixing ring 301. A rotating shaft 303 is fixedly connected to the mounting blocks 302. A limit block 304 is rotatably connected to the rotating shaft 303. Two protrusions 305 are fixedly connected to the top of the fixed ring 301. The limiting block 304 is inserted into the protrusions 305. A locking block 306 is slidably connected inside the protrusions 305. A locking groove 307 is opened on the limiting block 304. The end of the locking block 306 is engaged with the locking groove 307. The limiting block 304 has an "L" shaped structure. The end of the locking block 306 has an inclined structure. A spray gun 5 is installed at the end of the sand conveying pipe 2. A fixing block 6 is installed on the main body 1 of the sandblasting machine. The spray gun 5 is slidably connected to the fixing block 6. A limiting structure 7 is installed on the fixing block 6.

[0023] As a technical optimization of this utility model, a torsion spring 311 is sleeved on the rotating shaft 303. One end of the torsion spring 311 is fixedly connected to the rotating shaft 303, and the other end of the torsion spring 311 is fixedly connected to the limiting block 304. When the locking block 306 no longer limits the limiting block 304, the torsion spring 311 resets and drives the limiting block 304 to rotate, so that the limiting block 304 does not obstruct the disassembly of the sand conveying pipe 2, thereby making it more convenient for the operator to operate the limiting block 304. A guide groove 4 is provided on the fixing ring 301, and the sand conveying pipe 2 is slidably connected to the guide groove 4. The setting of the guide groove 4 facilitates the winding of the sand conveying pipe 2 onto the fixing ring 301.

[0024] As a technical optimization of this utility model, a connecting block 308 is fixedly connected to the locking block 306, and a first guide rod 309 is fixedly connected inside the protrusion 305. The connecting block 308 is slidably connected to the first guide rod 309. A spring 310 is sleeved on the outside of the first guide rod 309. The two ends of the spring 310 are fixedly connected to the protrusion 305 and the connecting block 308 respectively. The cooperation between the spring 310 and the connecting block 308 ensures the stability of the locking block 306 when it pops out and retracts.

[0025] As a technical optimization of this utility model, the fixed block 6 has a U-shaped cross-section, and the limiting structure 7 includes a stop block 701. The stop block 701 is slidably connected to the fixed block 6, and the stop block 701 abuts against the spray gun 5. The spray gun 5 can be quickly fixed by the cooperation of the fixed block 6 and the stop block 701. The end of the stop block 701 has a beveled structure and has a guiding function, making the operator more flexible when fixing the spray gun 5. A second guide rod 702 is fixedly connected to the fixed block 6, and the stop block 701 is slidably connected to the second guide rod 702. A tension spring 703 is sleeved on the second guide rod 702. One end of the tension spring 703 is fixedly connected to the fixed block 6, and the other end of the tension spring 703 is fixedly connected to the stop block 701. The second guide rod 702 can prevent the stop block 701 from slipping off the fixed block 6, and the tension spring 703 can make the stop block 701 more stable when it abuts against the spray gun 5.

[0026] In use, the sand conveying pipe 2 is first stored in the winding structure 3 when the device is not in use or needs to be transported. During operation, the sand conveying pipe 2 is passed through the guide groove 4 on the lower edge of the fixing ring 301 and then wound around the fixing ring 301. The guide groove 4 can guide the sand conveying pipe 2 to be wound neatly, making it more convenient for the operator to wind the sand conveying pipe 2. Then, the limiting block 304 is rotated, and the limiting block 304 drives the torsion spring 311 to deform and store force, rotating the limiting block 304 to be inserted with the protrusion 305. During the insertion process, the outer wall of the limiting block 304 abuts against the locking block 306 and slides away from the limiting block 304. At the same time, the limiting block 304 slides and abuts against the spring through the connecting block 308. When spring 310 is compressed, and the slot 307 on the limiting block 304 aligns with the locking block 306, spring 310 resets and drives the locking block 306 to engage in the slot 307, thereby effectively limiting the limiting block 304 and keeping its inner wall pressed against the sand conveying pipe 2. This effectively prevents the sand conveying pipe 2 from loosening or shifting on the fixing ring 301, ensuring the stable storage of the sand conveying pipe 2. When the sand conveying pipe 2 needs to be used, the locking block 306 is pressed, causing its end to disengage from the slot 307 of the limiting block 304. At this time, torsion spring 311 resets and drives the limiting block 304 to rotate away from the protrusion 305, thereby releasing the limiting block 304 from the sand conveying pipe. The obstruction of pipe 2 gradually pulls the sand conveying pipe 2 out of the fixing ring 301 to meet the length requirements of the sandblasting operation. After the sand conveying pipe 2 is fixed, the spray gun 5 is then fixed by pushing it into the groove of the fixing block 6. Since the end of the stop block 701 has a sloping structure and a guiding function, when the spray gun 5 contacts the stop block 701, the spray gun 5 slides upward against the stop block 701. At the same time, the sliding of the stop block 701 drives the extension of the tension spring 703. When the spray gun 5 is completely inserted into the groove on the fixing block 6, the spray gun 5 no longer contacts the stop block 701. At this time, the tension spring 703 resets and drives the stop block 701 to slide downward, so that the inner wall of the stop block 701 contacts the spray gun 5. This prevents the spray gun 5 from slipping off the fixing block 6. The spray gun 5 is also equipped with a retaining ring located on the side of the fixing block 6, which can prevent the spray gun 5 from slipping off the side of the fixing block 6, further increasing the stability of the spray gun 5. The spray gun 5 is fixed by the cooperation of the fixing block 6 and the limiting structure 7. When the spray gun 5 is not in use, it can be fixed on the fixing block 6 to avoid the spray gun 5 being placed directly on the ground and rubbing and colliding with surrounding objects, which would cause surface wear and loosening of internal parts. It also prevents the spray gun 5 from being suspended after the sand conveying pipe 2 is wrapped around the fixing ring 301, thus preventing the spray gun 5 from colliding and being damaged with the sandblasting machine body 1. Therefore, it can protect the spray gun 5.When surface treatment of the valve is required, turn on the power and compressed air valve of the sandblasting machine body 1, adjust the sandblasting pressure, sand volume and other parameters, hold the spray gun 5, aim the nozzle of the spray gun 5 at the part of the valve surface that needs to be treated, maintain an appropriate distance and angle, press the trigger of the spray gun 5, and start the sandblasting operation on the valve. By moving the spray gun 5, the valve surface is sandblasted evenly until the desired surface treatment effect is achieved.
