Description

Technical Field

[0001] This utility model relates to the technical field of sandblasting, specifically to a sandblasting device for spiral road spikes. Background Technology

[0002] Spiral rail spikes are an important component of railway fastening systems, used to secure railway tracks and ensure the safe and stable operation of trains. In actual railway operations, the effectiveness of spiral rail spikes directly impacts the safety and stability of the railway. Through continuous practical testing and technological improvements, the performance of spiral rail spikes has been verified and enhanced.

[0003] According to Chinese Patent No. CN220839712U, a surface treatment sandblasting device for screw production includes a protective shell. Inside the protective shell is a sandblasting basket. A servo motor is fixedly connected to the right side of the protective shell, and a sealed bearing is fixedly embedded in the right side of the protective shell. The right end of the sandblasting basket passes through the sealed bearing and is fixedly connected to the output end of the servo motor. A pneumatic sandblasting box is fixedly connected to the left side of the protective shell. The output end of the pneumatic sandblasting box is fixedly connected to a sandblasting pipe. The output end of the sandblasting pipe passes through the protective shell and extends into the interior of the sandblasting basket. A sandblasting head is fixedly connected to the output end of the sandblasting pipe. A set of ventilation holes is opened on the upper surface of the protective shell, and an activated carbon filter plate is fixedly connected to the inner top wall of the protective shell.

[0004] In the above solution, the bolts are sandblasted using a sandblasting pipe and a sandblasting head. However, this method still has the following drawbacks: after sandblasting, the diameter of the sandblasting material may shrink due to wear, which reduces the sandblasting effect on the screws. Utility Model Content

[0005] The purpose of this invention is to provide a sandblasting device for spiral road spikes to solve the problem that the diameter of the sandblasting material may shrink due to wear, thereby reducing the sandblasting effect on the screws.

[0006] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: a sandblasting device for spiral road spikes, comprising a machine body shell, a plurality of sandblasting machines fixed on one side of the machine body shell, a plurality of support plates fixed on both sides of the interior of the machine body shell, a sliding plate detachably provided inside the machine body shell, the support plates supporting the sliding plate upwards, a plurality of storage holes opened on the top surface of the sliding plate, a spiral road spike body detachably provided inside the storage holes, a fixing frame fixed inside the machine body shell, a separation net fixed inside the fixing frame, and a storage box slidably provided below the fixing frame.

[0007] Preferably, the top surface of the sliding plate is fixed with a plurality of support columns, wherein two support columns form a group, and each group of support columns supports the spiral rail spike body upwards. The top surface of the sliding plate is fixed with two handles.

[0008] Preferably, a closed door is rotatably provided on one side of the casing, and the casing and the closed door are rotatably connected by a hinge. An installation opening is provided on one side of the closed door, and a transparent plate is fixed inside the installation opening.

[0009] Preferably, a sliding groove is provided on the side of the closed door near the outer casing of the machine body. An electric push rod is fixed to the bottom surface of the sliding groove. A baffle plate is slidably arranged inside the sliding groove. The bottom surface of the baffle plate is fixed to the top of the telescopic rod of the electric push rod. A PLC controller is provided on one side of the closed door. The electric push rod is electrically connected to the PLC controller. The sandblasting machine is electrically connected to the PLC controller.

[0010] Preferably, the top surface of the outer casing has several ventilation holes, and a purification block is fixed inside the ventilation holes.

[0011] Preferably, a base post is fixed at each of the four corners of the bottom surface of the casing, and an anti-slip pad is fixed at the bottom end of the base post.

[0012] Compared with existing technologies, a sandblasting device for spiral road spikes that adopts the above-mentioned technical solution has the following beneficial effects:

[0013] First, the staff will place the spiral rail spike body in the storage hole on the sliding plate and support it with the support column to reduce the contact area between the spiral rail spike body and the sliding plate. Then, the sandblasting machine will inject a high-speed airflow carrying reinforcing steel shot into the interior of the machine body. The diameter of the reinforcing steel shot is 2mm, which can increase the roughness of the spiral rail spike body surface after grinding and reduce the probability of the spiral rail spike body popping out. The surface of the spiral rail spike body can then be sandblasted. During the sandblasting process, the diameter of the reinforcing steel shot may decrease due to long-term wear. Since the aperture of the separation mesh is slightly smaller than 2mm, when the reduced diameter reinforcing steel shot falls on the top surface of the separation mesh, the reinforcing steel shot will pass through the separation mesh and fall into the interior of the storage box, which can remove the reduced diameter reinforcing steel shot and increase the effect of sandblasting the surface of the spiral rail spike body.

[0014] 2. When the sandblasting machine starts working, the PLC controller will receive the information that the sandblasting machine has started working. Then the PLC controller will send a command to the electric push rod to control the extension rod of the electric push rod to rise, which will push the baffle plate to slide upward inside the sliding groove and block it between the transparent plate and the machine body shell to prevent the moving steel shot from damaging the transparent plate made of tempered glass.

[0015] Third, the air inside the casing can be exchanged and circulated with the outside environment through the vents. When the air passes through the vents, it is filtered by the activated carbon filter block inside to remove dust and other impurities, preventing dust from being directly discharged into the external environment and preventing dust from entering the lungs of the staff through the respiratory tract, thus increasing the safety of the staff.

[0022] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0023] like Figures 1-3 As shown, a sandblasting device for spiral road spikes includes a housing 1, with several sandblasting machines 2 fixed on one side of the housing 1, several support plates 3 fixed on both sides of the interior of the housing 1, a sliding plate 4 detachably installed inside the housing 1, the support plates 3 supporting the sliding plate 4 upwards, several storage holes 5 opened on the top surface of the sliding plate 4, a spiral road spike body 6 detachably installed inside the storage holes 5, a fixing frame 7 fixed inside the housing 1, a separation net 8 fixed inside the fixing frame 7, a storage box 9 slidably installed below the fixing frame 7, several support columns 10 fixed on the top surface of the sliding plate 4, two support columns 10 forming a group, each group of support columns 10 supporting the spiral road spike body 6 upwards, and two handles 11 fixed on the top surface of the sliding plate 4.

[0024] In use, the operator first places the spiral spike body 6 in the storage hole 5 on the sliding plate 4 and supports it with the support column 10 to reduce the contact area between the spiral spike body 6 and the sliding plate 4. Then, the sandblasting machine 2 injects a high-speed airflow carrying reinforced steel shot into the interior of the machine body shell 1. The reinforced steel shot has a diameter of 2mm, which can increase the roughness of the surface of the spiral spike body 6 after grinding and reduce the probability of the spiral spike body 6 popping out. This allows the surface of the spiral spike body 6 to be sandblasted. During the sandblasting process, the diameter of the reinforced steel shot may decrease due to long-term wear. Since the aperture of the separation mesh 8 is slightly smaller than 2mm, when the reinforced steel shot with a reduced diameter falls on the top surface of the separation mesh 8, it will pass through the separation mesh 8 and fall into the interior of the storage box 9. This removes the reinforced steel shot with a smaller diameter and increases the sandblasting effect on the surface of the spiral spike body 6.

[0025] like Figure 2 and Figure 4 As shown, a closed door 12 is rotatably installed on one side of the machine body shell 1. The machine body shell 1 and the closed door 12 are rotatably connected by a hinge. An installation port 13 is opened on one side of the closed door 12. A transparent plate 14 is fixed inside the installation port 13. A sliding groove 15 is opened on the side of the closed door 12 near the machine body shell 1. An electric push rod 16 is fixed on the bottom surface of the sliding groove 15. A baffle plate 17 is slidably installed inside the sliding groove 15. The bottom surface of the baffle plate 17 is fixed to the top of the telescopic rod of the electric push rod 16. A PLC controller is installed on one side of the closed door 12. The electric push rod 16 is electrically connected to the PLC controller. The sandblasting machine 2 is electrically connected to the PLC controller.

[0026] During use, when the sandblasting machine 2 starts working, the PLC controller will receive the information that the sandblasting machine 2 has started working. Then the PLC controller will send a command to the electric push rod 16 to control the extension rod of the electric push rod 16 to rise, which will push the shield 17 to slide upward inside the sliding groove 15 and shield between the transparent plate 14 and the machine body shell 1, preventing the moving steel shot from damaging the transparent plate 14 made of tempered glass.

[0027] like Figure 1 and Figure 2 As shown, the top surface of the outer casing 1 has several ventilation holes 18, and a purification block 19 is fixed inside the ventilation holes 18. The bottom corners of the outer casing 1 are respectively fixed with base posts 20, and the bottom ends of the base posts 20 are fixed with anti-slip pads 21.

[0028] During use, the air inside the outer casing 1 can be exchanged and circulated with the external environment through the vent 18. When the air passes through the vent 18, it is filtered by the purification block 19 made of activated carbon inside to remove dust and other impurities from the air, preventing dust from being directly discharged into the external environment and preventing dust from entering the lungs along the respiratory tract of the staff, thus increasing the safety of the staff.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
