Description

Technical Field

[0001] The present invention relates to a shot blasting machine, and in particular, to a hoisting type shot blasting cleaning machine for air compressor accessories and its alignment buffer device. Background Art

[0002] An air compressor air storage tank is a large tank accessory made of steel plates. After it is manufactured, it is prone to rust. Before the air storage tank is painted, its surface needs to be shot blasted to remove rust. The shot blasting process is a metal surface treatment process. Its process principle is generated by the impact of high-speed moving shot on the metal surface. While removing dirt and rust, it can also improve the surface quality of the workpiece and strengthen the surface of the workpiece to a certain extent.

[0003] The equipment used in the shot blasting process is usually a shot blasting machine. For large parts such as shot blasting air storage tanks, a crane and a hook are usually used to hang multiple air storage tanks and then send them into the shot blasting machine for shot blasting. During the shot blasting process, it is necessary to rotate the hook to ensure uniform shot blasting on the surface of the air storage tank. A motor is arranged above the shot blasting machine, and gears are arranged on the hook and the output shaft of the motor. The hook is driven by the motor to rotate. However, during the production process, the operator found that when the crane drives the hook into the shot blasting machine, due to inertia, the hook will rotate to a certain extent, resulting in the inability of the two gears to directly complete meshing. The teeth of the gears are prone to cracks and chipping after collision, affecting their service life. Summary of the Invention

[0004] In view of this, the first object of the present invention is to provide an alignment buffer device, which has the functions of aligning the gears and buffering.

[0005] To solve the above technical problems, the technical solution of the present invention is: an alignment buffer device for a shot blasting cleaning machine, including a shot blasting machine body and a driving hook. A driven gear is arranged on the driving hook. The device further includes a sliding table, a sliding block and a gear fixing frame. The sliding table is fixedly arranged above the shot blasting machine. The sliding block is slidably arranged on the sliding table. A rubber block is also arranged at the tail of the sliding block. The gear fixing frame is arranged on the sliding block. A power component is also arranged at the bottom of the sliding block. The gear fixing frame moves upward through the power component during the sliding process of the sliding block. A limiting groove is opened on the gear fixing frame. The limiting groove is used to clamp the driven gear and limit the rotation of the driving hook.

[0006] By the above technical means, the gear fixing frame is driven to move upward through the power component, so that the limiting groove clamps the driven gear, restricting its rotation before meshing, thus facilitating direct docking during meshing. By arranging the rubber block, the impact force generated during gear docking is reduced.

[0007] Preferably, a guiding column is provided at the bottom of the gear fixing bracket, a sliding hole is formed in the sliding block, and a buffer assembly is further provided between the power assembly and the guiding column. The buffer assembly is used to receive the power generated by the power assembly and apply it to the gear fixing bracket.

[0008] By the above technical means, through the sliding arrangement between the guiding column and the sliding hole, the rotation of the gear fixing bracket is restricted. A buffer assembly is provided between the power assembly and the guiding column to prevent the gear fixing bracket from being jammed with the driven gear when moving upward.

[0009] Preferably, the buffer assembly includes a first sliding plate, a second sliding plate, a sliding column and a buffer spring. A sliding groove is formed at the bottom of the sliding block. The first sliding plate and the second sliding plate are both slidably arranged in the sliding groove. The sliding column is arranged at the upper end of the first sliding plate and passes through the second sliding plate. A stroke end cover for restricting the second sliding plate from separating from the sliding column is arranged at the end of the sliding column. The buffer spring is arranged between the first sliding plate and the second sliding plate and sleeved on the sliding column. The guiding column is fixed on the second sliding plate, and the power assembly is arranged at the lower end of the first sliding plate.

[0010] By the above technical means, by arranging the spring between the first sliding plate and the second sliding plate, in the way of spring buffering, the force of the power assembly is converted into the compression force of the spring. By the rotation of the driving hook during movement, when the limiting groove aligns with the driven gear, the compression force of the spring is released to achieve the purpose of restricting the driven gear.

[0011] Preferably, the power assembly includes a pair of rollers and a wheel frame. An avoidance groove one is formed in the middle of the sliding table. Stroke guiding grooves are formed on both sides of the avoidance groove one. The rollers are slidably arranged in the stroke guiding grooves. The stroke guiding groove includes a translation part, an inclined part, a jacking part and a separating part connected in sequence. When the roller moves to the inclined part, it moves upward. When the roller moves to the separating part, the gear fixing bracket separates from the driven gear.

[0012] By the above technical means, through the cooperation between the rollers and the stroke guiding grooves, the wheel frame moves up and down. By arranging the separating part, after the driven gear and the motor gear are engaged, the gear sliding bracket is separated from the driven gear to prevent the driven gear from being unable to rotate.

[0013] Preferably, a rubber block is fixedly arranged at the side end of the avoidance groove one. When the driving hook passes through the rubber block, it abuts against the side end face of the rubber block and rotates.

[0014] By the above technical means, by arranging the rubber block, the driving hook rotates to a certain extent, preventing the problem that the driven gear does not rotate and cannot be clamped into the limiting groove.

[0015] Preferably, the sliding block and the gear fixing frame are both provided with an avoidance groove 2 for the driving hook to enter, and the driving hook drives the sliding block to move when entering the shot blasting machine, and the sliding table is also provided with a reset component for driving the sliding block to reset.

[0016] Through the above technical means, by opening the second avoidance groove, when the driving hook is against the sliding block, it will drive the sliding block to move together, while ensuring that the central axis of the gear fixing frame and the driven gear coincide, and the sliding block will follow the driving hook after it moves out through the reset component.

[0017] Preferably, the reset assembly comprises a clockwork box, a steel wire rope and a guide wheel, one end of the steel wire rope is fixed in the clockwork box, and the other end of the steel wire rope is passed around the guide wheel and fixed on the sliding block.

[0018] Through the above technical means, the mainspring box is used as the power source, and the sliding block is connected by a wire rope, so that the reset function can be completed without connecting to electricity.

[0019] The second object of the present invention is to provide an air compressor accessory hoisting type shot blasting cleaning machine, which has the function of squaring gears and buffering.

[0020] The technical solution of the present invention is: an air compressor accessory hoisting shot blasting cleaning machine, including a straightening buffer device, a driving guide rail is arranged above the shot blasting machine body, a power motor and a lifting motor are slidably arranged on the driving guide rail, the driving hook is arranged at the output end of the lifting motor, a driven gear is fixedly arranged on the driving hook, a connecting column is opened in the middle of the driven gear, the limiting groove cooperates with the connecting column, a gear motor is also arranged on the upper end of the shot blasting machine body, and a driving gear cooperating with the driven gear is arranged at the output end of the gear motor.

[0021] Through the above technical means, by setting a connecting column in the middle of the driven gear, the gear is lightweight and convenient to cooperate with the limit groove. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0025] Embodiment 1:

[0026] A straightening buffer device for a shot blasting machine comprises a shot blasting machine body 1 and a driving hook 2. The shot blasting machine body 1 is provided with a groove for the driving hook 2 to enter. The driving hook 2 is provided with a driven gear 3, which can rotate the driving hook 2 by meshing with the motor gear. The device also comprises a sliding table 4, a sliding block 5 and a gear fixing frame 6. The sliding table 4 is fixedly arranged above the shot blasting machine. An avoidance groove 7 is provided in the middle of the sliding table 4. The sliding block 5 and the gear fixing frame 6 are both provided with an avoidance groove 8 for the driving hook 2 to enter. The sliding block 5 is slidably arranged on the sliding table 4. The driving hook 2 enters the shot blasting machine body 1. When the gear is in the pill machine, it gradually enters the avoidance groove 8. At this time, the driving hook 2 drives the sliding block 5 to move together. A rubber pad 9 is also provided at the tail of the sliding block 5. When the sliding block 5 moves to the bottom, the rubber block 28 hits the tail of the sliding platform 4 to reduce the impact force when the gears are connected. The gear fixing frame 6 is arranged on the sliding block 5. A power assembly 10 is also arranged at the bottom of the sliding block 5. The gear fixing frame 6 moves upward through the power assembly 10 during the sliding process of the sliding block 5. A limiting groove 11 is provided on the gear fixing frame 6. The limiting groove 11 is used to clamp the driven gear 3 and limit the rotation of the driving hook 2.

[0027] A guide post 12 is provided at the bottom of the gear fixing bracket 6, and a sliding hole 13 is formed in the sliding block 5. Through the sliding setting between the guide post 12 and the sliding hole 13, the rotation of the gear fixing bracket 6 is restricted. A buffer assembly 14 is further provided between the power assembly 10 and the guide post 12. The buffer assembly 14 is used to receive the power generated by the power assembly 10 and apply it to the gear fixing bracket 6. When the limit groove 11 does not coincide with the gear connecting column 38, a certain force is applied to the gear fixing bracket 6. When the limit groove 11 and the gear connecting column 38 can be engaged, the gear fixing bracket 6 is driven to move upward to prevent the gear fixing bracket 6 from jamming with the driven gear 3 when moving upward.

[0028] The buffer assembly 14 includes a first sliding plate 15, a second sliding plate 16, a sliding column 17 and a buffer spring 18. A sliding groove 19 is formed at the bottom of the sliding block 5. The first sliding plate 15 and the second sliding plate 16 are both slidably arranged in the sliding groove 19. The sliding column 17 is fixed to the upper end of the first sliding plate 15 and passes through the second sliding plate 16. A stroke end cover 20 for restricting the second sliding plate 16 from separating from the sliding column 17 is provided at the end of the sliding column 17. The buffer spring 18 is arranged between the first sliding plate 15 and the second sliding plate 16 and sleeved on the sliding column 17. The guide post 12 is fixed to the second sliding plate 16. The power assembly 10 is arranged at the lower end of the first sliding plate 15. When the power assembly 10 moves upward, the first sliding plate 15 moves upward and drives the sliding column 17 to move. At this time, if the gear fixing bracket 6 cannot be engaged due to the misalignment of the limit groove 11 and the driven gear 3, the second sliding plate 16 cannot move, and the buffer spring 18 is compressed. When the driving hook 2 drives the driven gear 3 to rotate due to an external force, the driven gear 3 will gradually approach the limit groove. When they coincide, the pressure of the buffer spring 18 is released, and the second sliding plate 16 is pushed upward to complete the engagement.

[0029] The power assembly 10 includes a pair of rollers 21 and a wheel frame 22. The wheel frame 22 is fixedly connected to the first sliding plate 15. Stroke guide grooves 23 are formed on both sides of the first avoidance groove 7. The rollers 21 are slidably arranged in the stroke guide grooves 23. The stroke guide groove 23 includes a translation part 24, an inclined part 25, an ejection part 26 and a separation part 27 connected in sequence. When the roller 21 is in the translation part 24, the buffer spring 18 does not generate pressure on the second sliding plate 16. When the roller 21 moves to the inclined part 25, it moves upward. At this time, the first sliding plate 15 follows the wheel frame 22 to move upward and compresses the buffer spring 18. When the roller 21 moves to the ejection part 26, the first sliding plate 15 moves to the limit position. When the roller 21 moves to the separation part 27, the first sliding plate 15 follows the wheel frame 22 to move downward and pulls the second sliding plate 16 down. At this time, the gear fixing bracket 6 is separated from the driven gear 3.

[0030] A rubber block 28 is also fixedly provided at the side end of the avoidance groove 7. When the driving hook 2 passes through the rubber block 28, it abuts against the side end surface of the rubber block 28 and rotates, thereby preventing the problem that the driven gear 3 does not rotate due to insufficient external force and cannot be stuck in the limit groove 11.

[0031] The sliding table 4 is also provided with a reset component 29 for driving the sliding block 5 to reset. The reset component 29 includes a clockwork box 30, a wire rope 31 and a guide wheel 32. A clockwork spring 33 and a rotating rod 34 are provided in the clockwork box 30. The clockwork spring 33 is used to drive the rotating rod 34 to rotate. One end of the wire rope 31 is fixed to the rotating rod 34 in the clockwork box 30, and the other end passes around the guide wheel 32 and is fixed to the sliding block 5. When the sliding block 5 follows the driving hook 2 to move to the innermost side and completes the engagement, the clockwork spring 33 is tightened and generates a reverse force. When the driving hook 2 moves back, the reverse force of the clockwork spring 33 is released, thereby driving the rotating rod 34 to rotate. The rotating rod 34 drives the sliding block 5 to move back by winding the wire rope 31.

[0032] Embodiment 2:

[0033] A kind of air compressor accessory hoisting shot blasting cleaning machine, including a straightening buffer device, a driving guide rail 35 is arranged above the shot blasting machine body 1, the driving guide rail 35 is in a herringbone shape, a pair of power motors 36 and a pair of lifting motors 37 are slidingly arranged on the driving guide rail 35, and the output ends of the lifting motors 37 are provided with driving hooks 2, which move the driving hooks 2 up and down by means of ropes. Two driving hooks 2 are provided to load and unload materials in advance, a driven gear 3 is fixedly arranged on the driving hook 2, and a connecting column 38 is provided in the middle of the driven gear 3, so as to ensure the strength of the gear while reducing its weight, the shape of the limiting groove 11 is adapted to the connecting column 38, and the limiting groove 11 is clamped on the three connecting columns 38 when clamping, and the number of teeth of the driven gear 3 is a multiple of the connecting column 38 to ensure that there will be no problems during meshing, and a gear motor 39 is also arranged on the upper end of the shot blasting machine body 1, and a driving gear 40 cooperating with the driven gear 3 is arranged at the output end of the gear motor 39.

[0034] Of course, the above are only typical examples of the present invention. In addition, the present invention may also have many other specific implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
