Description

Technical Field

[0001] The present invention relates to the technical field of shot blasting for power distribution cabinet shells, and specifically to a shot blasting device for high and low voltage power distribution cabinet shells. Background Technique

[0002] Shot blasting is the name of a mechanical surface treatment process. Similar processes include sandblasting and shot peening. Shot blasting is a cold treatment process, which is divided into shot blasting cleaning and shot peening. As the name implies, shot blasting cleaning is to remove impurities such as surface oxide scales to improve the appearance quality. Shot peening is to use a stream of high-speed moving shot (60 - 110 m / s) to continuously impact the surface of the workpiece to be strengthened, forcing the following changes to occur in the surface and surface layer (0.10 - 0.85 mm) of the target material during the cyclic deformation process: 1. The microstructure is modified; 2. Residual compressive stress is introduced into the non-uniform plastically deformed outer surface layer, and residual tensile stress is generated in the inner surface layer; 3. The surface roughness of the outer surface changes. Influence: It can improve the fatigue fracture resistance of the material, prevent fatigue failure, plastic deformation and brittle fracture, and improve the fatigue life.

[0003] When the existing shot blasting device performs shot blasting on the power distribution cabinet shell, it is necessary to input the power distribution cabinet into the equipment, quickly eject the shot onto the outer wall of the power distribution cabinet shell, and then output it after the shell of the power distribution cabinet is evenly shot blasted with the rotation of the power distribution cabinet. However, the existing equipment has low operating efficiency during the input and output of the power distribution cabinet, is time-consuming and laborious to handle, and the power distribution cabinet has a large turning amplitude during the shot blasting process, which is easy to collide with the machine body.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. A shot blasting device for the shell of a high - and - low - voltage power distribution cabinet provided by the present invention solves the problems that when the existing shot blasting device for the shell of a high - and - low - voltage power distribution cabinet is used, it is difficult for the power distribution cabinet to be slowly and evenly flipped inside the device, and the conveying efficiency of the power distribution cabinet is relatively low. The power distribution cabinet is placed on the conveyor belt, and the conveyor belt conveys the power distribution cabinet upward, so that the power distribution cabinet falls into the shot blasting cylinder through the conveying port. A large number of buffer balls are arranged in the shot blasting cylinder. The buffer balls can be made of solid metal balls wrapped with rubber pads on the outside.

The shot in the collection frame falls into the collection pipe and is then pumped into the shot blasting machine for recycling;

[0016] 2. A shot blasting device for the shell of a high - and - low - voltage power distribution cabinet provided by the present invention. During the shot blasting process, the driving motor drives the first rotating shaft to rotate clockwise, thereby driving the second rotating shaft to rotate clockwise through the first transmission belt and the second transmission belt, making the arc - shaped ring rotate clockwise. At this time, the first electric telescopic rod retracts, making the buffer plate close to the inner wall side of the arc - shaped ring. Then, during the rotation of the arc - shaped ring, the top of the buffer plate contacts the outer wall of the power distribution cabinet. During the contact process, the buffer spring is compressed. As the arc - shaped ring rotates, the top of the buffer plate continuously pushes the bottom side of the power distribution cabinet until the power distribution cabinet flips to the upper side of the flip - over plate, and a flip - over operation of the power distribution cabinet can be realized. The power distribution cabinet rotates and is supported inside the buffer balls, and then the shot blasting operation can continue to be carried out on different positions of the outer shell of the power distribution cabinet through the first output frame and the second output frame;

[0017] 3. A shot blasting device for the shell of a high - and - low - voltage power distribution cabinet provided by the present invention. When the shot blasting is completed, control one end of the flip - over plate to rotate to the bottom position of the conveying port. At this time, control the first electric telescopic rod to push the flip - over plate to rotate upward and tilt. Then, drive the first rotating shaft to rotate counterclockwise through the driving motor, so that the second rotating shaft and the arc - shaped ring both rotate in the reverse direction. The driving disc rotates, and the tip of the ratchet continuously contacts the side of the helical tooth block, pushing the helical tooth block to make the rotating disc rotate, driving the box door to slowly open. During the process of the arc - shaped ring rotating one circle, the flip - over plate rotates from the upper side to the position where it fits the top surface of the power distribution cabinet, gradually rotating the power distribution cabinet to the upper side of the flip - over plate for support until the power distribution cabinet reaches the position of the conveying port.

[0032] The output mechanism 13 includes a box door 14 rotatably connected to both sides of the conveying port 4.

[0035] The driving member 18 includes a driving motor 20 fixedly mounted on the outer wall of the shot blasting cylinder 2. The model of the driving motor 20 is preferably YYHS-40. The output end of the driving motor 20 is coaxially fixedly connected with the first rotating shaft 21. The outer wall of the shot blasting cylinder 2 is rotatably connected with the second rotating shaft 22 and multiple groups of third rotating shafts 23. The outer wall of the first rotating shaft 21 is transmission-connected with multiple groups of first transmission belts 24. The multiple groups of first transmission belts 24 are all transmission-connected with the second rotating shaft 22, the third rotating shaft 23 and the outer wall of the arc ring 16. An opening and closing member 25 for linking the box door 14 to open and close when the arc ring 16 rotates is provided on the shot blasting cylinder 2. The outer wall of the first rotating shaft 21 is transmission-connected with a second transmission belt 37 transmission-connected to the outer wall of the pulley on the second rotating shaft 22 through a pulley.

[0036] The opening and closing member 25 includes a driving shaft 26 fixedly mounted on the box door 14, a planetary gear reducer 27 connected to the driving shaft 26 is fixedly connected to the shot blasting cylinder 2, a rotating disk 28 is coaxially fixedly connected to the input end of the planetary gear reducer 27, and a driving disk 29 is coaxially fixedly connected to one end of the second rotating shaft 22. A plurality of groups of clockwork shafts 30 are provided on the driving disk 29, and a ratchet 31 rotatably connected to the driving disk 29 is provided on the clockwork shaft 30. A plurality of groups of bevel gear blocks 32 are evenly and fixedly connected to the outer wall of the rotating disk 28.

[0037] The circulation part 9 includes a collecting frame 33 fixedly mounted on the bottom of the shot blasting cylinder 2, and a plurality of collecting holes 34 are evenly arranged on the bottom of the shot blasting cylinder 2. The bottom of the collecting frame 33 is connected with a collecting pipe 35, one end of the collecting pipe 35 is connected with the feeding end of the shot blasting machine 5, and the output end of the shot blasting machine 5 is connected with two groups of output pipes 36, the second output frame 8 is connected with one end of the output pipe 36, and the first output frame 7 is connected with the output end of the shot blasting machine 5. The collecting holes 34 pass through the buffer pad 42 and are connected with the shot blasting cylinder 2 and the collecting frame 33.

[0038] In this implementation, the power distribution cabinet 43 is placed on the conveyor belt 3, and the conveyor belt 3 transports the power distribution cabinet 43 upward, so that the power distribution cabinet 43 falls into the shot blasting cylinder 2 through the conveying port 4. A large number of buffer balls 11 are provided in the shot blasting cylinder 2. The diameter of the buffer balls 11 is much larger than the inner diameter of the collection hole 34, and the diameter of the shot is smaller than the inner diameter of the collection hole 34, so that the shot will pass through the gaps between the buffer balls 11 inside the shot blasting cylinder 2 and fall into the collection hole 34, and is recycled through the collection frame 33. The buffer balls 11 can be made of solid metal balls with rubber pads wrapped on the outside. They have a certain buffer force and good support. The buffer balls 11 roll in the shot blasting cylinder 2 and evenly support the bottom of the power distribution cabinet 43. The shot is continuously sprayed onto the outer wall of the power distribution cabinet 43 through the first output frame 7 and the second output frame 8 by the shot blaster 5, and the shot blasting operation can be completed. The shot falls into the collection pipe 35 in the collection frame 33 and is then pumped into the shot blaster 5 for recycling.

[0039] During the shot blasting process, the driving motor 20 drives the first rotating shaft 21 to rotate clockwise, thereby driving the second rotating shaft 22 to rotate clockwise through the first transmission belt 24 and the second transmission belt 37. The outer wall of the first transmission belt 24 is attached to the outer wall of the arc-shaped ring 16, so that the arc-shaped ring 16 rotates clockwise. At this time, the first electric telescopic rod 19 retracts, so that the buffer plate 41 approaches the inner wall side of the arc-shaped ring 16. Then, during the rotation of the arc-shaped ring 16, the top of the buffer plate 41 is brought into contact with the outer wall of the power distribution cabinet 43. During the contact process, the buffer spring 40 is compressed. As the arc-shaped ring 16 rotates, the top of the buffer plate 41 continuously pushes the bottom side of the power distribution cabinet 43 until the power distribution cabinet 43 is flipped to the upper side of the flip plate 12, and a flip operation of the power distribution cabinet 43 can be realized. The power distribution cabinet 43 rotates and is supported inside the buffer balls 11, and then the shot blasting operation can continue to be carried out on different positions of the outer shell of the power distribution cabinet 43 through the first output frame 7 and the second output frame 8.

[0040] When the shot blasting is completed, one end of the flip plate 12 is controlled to rotate to the bottom of the conveying port 4. At this time, the first electric telescopic rod 19 is controlled to push the flip plate 12 to rotate and tilt upward, and then the first rotating shaft 21 is driven by the driving motor 20 to rotate counterclockwise, so that the second rotating shaft 22 and the arc ring 16 are rotated in the opposite direction, and the driving disk 29 rotates to drive the tip of the ratchet 31 to continuously conflict with the side of the bevel gear block 32, pushing the bevel gear block 32 to rotate the rotating disk 28, and the rotating disk 28 drives the planetary gear reducer 27 to make the driving shaft 26 rotate slowly, thereby driving the box door 14 to slowly open. It is larger than the circumference of the second rotating shaft 22, so the second rotating shaft 22 needs to rotate multiple times to drive the arc ring 16 to rotate one circle. During the process of the arc ring 16 rotating one circle, the flip plate 12 rotates from the upper side to a position that fits the top surface of the distribution cabinet 43, and gradually rotates the distribution cabinet 43 to the upper side of the flip plate 12 for support until the distribution cabinet 43 reaches the position of the conveying port 4. At this time, the box door 14 is just opened and tilted upward. Starting the second electric telescopic rod 38 drives the pushing block 39 to be pushed outward, so that the distribution cabinet 43 can be pushed onto the conveyor belt 3 for downward output, which greatly improves the transportation efficiency of the distribution cabinet 43.

[0041] It is worth noting that during shot blasting, the second rotating shaft 22 drives the driving disk 29 to rotate clockwise. At this time, the arc surface position of the ratchet 31 rubs against the arc surface position of the bevel gear block 32. At the same time, one end of the box door 14 tends to cover downward due to gravity, and at this time, the driving shaft 26 is slowly driven to rotate in the opposite direction. During the process of the driving shaft 26 driving the rotating disk 28 to rotate rapidly through the planetary gear reducer 27, the inclined surface of the bevel gear block 32 is not limited by the arc surface of the ratchet 31, ensuring that the box door 14 can be closed during the first rotation of the arc ring 16. After the box door 14 is closed, the shot blaster 5 automatically opens for shot blasting operation. After that, the arc ring 16 continues to rotate, and the arc surface of the ratchet 31 will continuously contact the inclined surface of the bevel gear The contact will not cause the position of the box door 14 to change, and will not affect the rotation of the first transmission belt 24 and the arc ring 16. The arc length of the spacing between the first rotating shaft 21 and the second rotating shaft 22 is greater than the arc length of the opening of the arc ring 16, ensuring that the outer wall of the arc ring 16 can always be driven to rotate. The arc length of the opening of the arc ring 16 is the same as the arc length of the cross-section of the box door 14, which is convenient for the transportation of the distribution cabinet 43. The device can achieve stable flipping operation without fixing the distribution cabinet 43, greatly improving the loading and unloading efficiency, and also reducing the impact and wear of the distribution cabinet 43 during the rotation process, which is convenient for use. A screen (not shown) can also be provided in the collection frame 33 to separate the projectiles from the dust to prevent the dust from being drawn into the shot blaster 5 along with the projectiles.
