Description

Technical Field

[0001] The invention relates to the technical field of sandblasting equipment, in particular to a furnace tube sandblasting auxiliary device. Background Art

[0002] The sandblasting process uses compressed air as the power to form a high-speed jet beam, which sprays the material at high speed onto the surface of the workpiece to be processed, so that the surface of the workpiece obtains a certain degree of cleanliness and different degrees of roughness, and the mechanical properties of the workpiece surface are improved.

[0003] When the conventional sandblasting device is sandblasting the furnace tube, the movement of the sandblasting gun is not stable enough, which can easily lead to uneven sandblasting. Since sand particles are easily accumulated on the guide rail, when the sandblasting gun slides along the guide rail, it may jam and vibrate, thus affecting the quality of sandblasting. During the sandblasting process, sand particles are easy to splash into the sliding track, resulting in uneven movement of the running device, and may even damage the track and running device. This situation not only affects the sandblasting efficiency, but also increases the maintenance difficulty and cost of the equipment. Since the furnace tube is heavy, the existing sandblasting equipment can usually only sandblast part of the surface of the furnace tube, and it is difficult to achieve all-round sandblasting of the furnace tube. This is mainly because the position and angle of the sandblasting gun are difficult to adjust, and it is impossible to cover all surfaces of the furnace tube. Summary of the invention

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1

[0032] Reference Figure 1 to Figure 9 , is an embodiment of the present invention, which provides a furnace tube sandblasting auxiliary device, which includes a protection adjustment unit 100, which starts the sliding component 102 to move forward under the protection of the protection component 101, and the sliding component 102 is squeezed during movement to enable the protection component 101 to be opened and closed, thereby preventing sand from splashing into the unused chute position. When the sliding component 102 moves to the maximum distance, it is squeezed by the adjustment component 104 to complete the downward movement. At the same time, the setting of the limit component 103 enables the telescopic sandblasting tube 103e of the sandblasting gun 103d to complete a 180-degree rotation, thereby sandblasting the bottom of the furnace tube.

[0033] Specifically, the protection adjustment unit 100 includes a protection component 101, a sliding component 102 fixedly connected to the top of the protection component 101, a limiting component 103 disposed inside the sliding component 102, and an adjustment component 104 disposed at the bottom of the limiting component 103;

[0034] The protection assembly 101 includes a supporting base plate 101a, a trapezoidal sliding groove 101b arranged on the top of the supporting base plate 101a, two groups of bending springs 101c symmetrically arranged at both ends of the trapezoidal sliding groove 101b, a protection plate 101d fixedly connected to one end of the bending spring 101c, a plurality of groups of connecting blocks 101e fixedly connected to the side wall of the supporting base plate 101a, and a processing table 101f fixedly connected to one end of the plurality of groups of connecting blocks 101e;

[0035] The sliding assembly 102 includes a driving motor 102a fixedly connected to one end of a supporting base plate 101a, a driving rod 102b arranged in the middle of a trapezoidal sliding groove 101b, a trapezoidal sliding block 102c threadedly connected to one end of the driving rod 102b, a supporting column 102d fixedly connected to the top of the supporting base plate 101a, a limiting protection frame 102e fixedly connected to the inner wall of the supporting column 102d, a convex sliding groove 102f arranged on the inner wall of the limiting protection frame 102e, and a limiting protection plate 102g fixedly connected to one end of the limiting protection frame 102e.

[0036] Furthermore, the limit assembly 103 includes a lifting limit rod 103a fixedly connected to the top of the trapezoidal sliding block 102c, a lifting limit groove 103b arranged in the middle of the lifting limit rod 103a, a lifting limit column 103c arranged in the middle of the lifting limit groove 103b, a sandblasting gun 103d slidingly connected to the top of the lifting limit column 103c, a telescopic sandblasting tube 103e rotatably connected to the side wall of the sandblasting gun 103d, a flip gear 103f fixedly connected to one end of the telescopic sandblasting tube 103e, a flip rack 103g fixedly connected to the side wall of the lifting limit rod 103a, and a locking piece 103h fixedly connected to the bottom of the sandblasting gun 103d.

[0037] Furthermore, the adjustment assembly 104 includes an extrusion push plate 104a fixedly connected to the top of the support base plate 101a, an L-shaped connecting rod 104b arranged on the top of the extrusion push plate 104a, an extrusion plate 104c fixedly connected to the bottom of the L-shaped connecting rod 104b, and an extrusion push block 104d fixedly connected to the bottom of the limit protection frame 102e.

[0038] Preferably, the driving motor 102a is started to drive the driving rod 102b to rotate, and the thread on the outer wall of the driving rod 102b makes the trapezoidal sliding block 102c threadedly connected to the driving rod 102b slide in the direction of the protective plate 101d under the limit in the trapezoidal sliding groove 101b, and the lifting limit rod 103a fixedly connected to the top of the trapezoidal sliding block 102c slides along with the trapezoidal sliding block 102c, and when the arc surface at one end of the lifting limit rod 103a moves to contact the arc surface adapted to one end of the two symmetrical groups of protective plates 101d, an extrusion force is provided to the two groups of protective plates 101d, pulling the fixedly connected bending spring 101c to deform, and rotating around the inner wall of the hinged trapezoidal sliding groove 101b, so that the two groups of protective plates 101d are The sliding space formed between the plates 101d is adapted to the lifting limit rod 103a, so that the lifting limit rod 103a can slide through, and the two groups of protective plates 101d are in an inclined state, and the outer inclined surface blocks the splashed sand again, and sliding along the inclined surface can prevent the sand from splashing into the trapezoidal sliding groove 101b and hindering the sliding of the trapezoidal sliding block 102c, thereby ensuring the stability of the sandblasting gun 103d during the sandblasting process. The groups of protective plates 101d will only open to form a sliding space for passage when the lifting limit rod 103a moves to the phase position to generate an extrusion driving force. The groups of protective plates 101d that have not moved to the position remain in a closed state, which can effectively prevent the splashing of sand and improve the stability during operation.

[0039] Furthermore, the locking member 103h includes a shrinkage block 103h-1, two groups of unlocking grooves 103h-2 symmetrically arranged at both ends of the shrinkage block 103h-1, a shrinkage spring 103h-3 fixedly connected to the side wall of the unlocking groove 103h-2, a locking block 103h-4 fixedly connected to one end of the shrinkage spring 103h-3, and a locking groove 103h-5 arranged on the inner wall of the lifting limit groove 103b.

[0040] Preferably, when the lifting limit rod 103a moves to the maximum distance, the arc surface at the top of one end of the extrusion plate 104c contacts the arc surface at the bottom of one end of the extrusion push block 104d, and the extrusion plate 104c is subjected to the extrusion force of the extrusion push block 104d, and drives the fixedly connected sandblasting gun 103d to slide downward along the slidably connected lifting limit column 103c through the L-shaped connecting rod 104b. The sandblasting gun 103d is limited in the lifting limit groove 103b in the middle of the lifting limit rod 103a, and keeps sliding vertically downward, pushing the locking piece 103h connected to the bottom of the sandblasting gun 103d to move downward. When the shrink block 103h-1 moves downward, it is fixedly connected to the inner walls of the two sets of unlocking grooves 103h-2 inside the shrink block 103h-1. The contraction spring 103h-3 pulls the fixedly connected locking block 103h-4 to move downward, and the locking block 103h-4 is inside the locking groove 103h-5 of the inner wall of the lifting limit groove 103b, so that the sandblasting gun 103d remains in a fixed state, and the arc surface at the bottom of one end of the locking block 103h-4 contacts with the arc surface adapted at the bottom of the locking groove 103h-5, and is squeezed by the arc surface at the bottom of the locking groove 103h-5 to push the contraction spring 103h-3 to deform and contract toward the inside of the unlocking groove 103h-2. When the locking block 103h-4 is completely contracted into the unlocking groove 103h-2, the sandblasting gun 103d is unlocked as a whole, and the sandblasting gun 103d loses its lock and moves to the bottom under the action of gravity;

[0041] The driving motor 102a is started again to drive the driving rod 102b to reverse, so that the trapezoidal sliding block 102c threadedly connected to the driving rod 102b slides in the direction of the initial position. When the inclined surface at one end of the extrusion plate 104c moves to contact the inclined surface adapted to the extrusion push plate 104a, the extrusion plate 104c is pushed by the inclined surface of the extrusion push plate 104a in the fixed state, and slides upward along the inclined surface of the extrusion push plate 104a. The contraction block 103h-1 fixedly connected to the extrusion plate 104c through the L-shaped connecting rod 104b drives the fixedly connected sandblasting gun 103d to slide upward on the slidably connected lifting limit column 103c. At the same time, under the limit of the lifting limit column 103c and the lifting limit groove 103b, the extrusion plate 104c is prevented from being pressed. 04c is displaced toward the other end by the thrust of the extrusion push plate 104a. When the locking block 103h-4 inside the contraction block 103h-1 moves to a parallel state with the locking groove 103h-5, the elastic force converted after the contraction spring 103h-3 loses the extrusion force pushes the locking block 103h-4 to move away from the unlocking groove 103h-2 until it enters the locking groove 103h-5, completing the limit locking of the sandblasting gun 103d. At the same time, when the telescopic sandblasting tube 103e follows the upward movement, the flip gear 103f fixed at one end moves to contact with the meshing rack 103g, and is limited by the rack 103g to complete a 180-degree flip, so that the sandblasting port of the contraction sandblasting tube 103 is at the top of the furnace tube again.

[0042] Furthermore, the unlocking groove 103h-2 is adapted to the locking block 103h-4, the locking groove 103h-5 is adapted to the locking block 103h-4, one end of the locking block 103h-4 is set as an arc surface, and the top of the L-shaped connecting rod 104b is fixedly connected to the bottom of the contraction block 103h-1.

[0043] Preferably, when the flip gear 103f fixedly connected at one end of the telescopic sandblasting tube 103e moves downward, it contacts the meshing flip rack 103g, and rotates under the limit of the flip rack 103g in the fixed state. Under the limit of the length of the flip rack 103g, the flip rack 103g can drive the fixedly connected telescopic sandblasting tube 103e to complete a 180-degree rotation around the rotatably connected sandblasting gun 103d. After the telescopic sandblasting tube 103e completes the flipping, it moves to the bottom of the lifting limit groove 103b under the action of gravity. At this time, the sandblasting port of the telescopic sandblasting tube 103 is at the bottom of the furnace tube.

[0044] Furthermore, both ends of the protection plate 101d are configured as arc-shaped surfaces, and one end of the protection plate 101d is hinged to the side wall of the trapezoidal sliding groove 101b.

[0045] Furthermore, the outer wall of the driving rod 102b is configured to be in a threaded state, and the trapezoidal sliding block 102c is adapted to the trapezoidal sliding groove 101b.

[0046] Furthermore, the flip gear 103f is adapted to the flip rack 103g, the lifting limit groove 103b is adapted to the sandblasting gun 103d, both ends of the lifting limit rod 103a are set as arc surfaces, and the arc surfaces at both ends of the lifting limit rod 103a are adapted to the arc surfaces at both ends of the protective plate 101d.

[0047] It should be noted that one end of the extrusion push plate 104a is set as an inclined surface, one end of the extrusion plate 104c is set as an inclined surface and is adapted to the inclined surface of one end of the extrusion push plate 104a, the top of the other end of the extrusion plate 104c is set as an arcuate surface, and the bottom of one end of the extrusion push block 104d is set as an arcuate surface and is adapted to the arcuate surface of the top of the other end of the extrusion plate 104c; when the lifting limit rod 103a moves to the maximum distance, the horizontal position of the sandblasting gun 103d exceeds the horizontal position of the furnace tube, so that the sandblasting gun 103d has enough space to descend and flip, and the length of the flip rack 103g can enable the flip gear 103f to complete a 180-degree rotation.

[0048] When in use, the protective plate 101d rotates to form a sliding space and a protective surface, and the drive motor 102a is started to drive the drive rod 102b to rotate. The thread on the outer wall of the drive rod 102b makes the trapezoidal sliding block 102c threadedly connected to the drive rod 102b slide in the direction of the protective plate 101d under the limit in the trapezoidal sliding groove 101b, and the lifting limit rod 103a fixedly connected to the top of the trapezoidal sliding block 102c slides with the trapezoidal sliding block 102c. When the arc surface at one end of the lifting limit rod 103a moves to contact the arc surface adapted to one end of the two symmetrical groups of protective plates 101d, an extrusion force is provided to the two groups of protective plates 101d, pulling the fixedly connected bending spring 101c to deform, and surrounding the inner wall of the hinged trapezoidal sliding groove 101b. The two sets of protective plates 101d rotate so that the sliding space formed between the two sets of protective plates 101d is adapted to the lifting limit rod 103a, so that the lifting limit rod 103a can slide through, and the two sets of protective plates 101d are in an inclined state, and the outer inclined surface blocks the splashed sand again, and sliding along the inclined surface can prevent the sand from splashing into the trapezoidal sliding groove 101b and hindering the sliding of the trapezoidal sliding block 102c, thereby ensuring the stability of the sandblasting gun 103d during the sandblasting process. The several sets of protective plates 101d will only open to form a sliding space for passage when the lifting limit rod 103a moves to the phase position to generate an extrusion driving force. The several sets of protective plates 101d that have not moved to the position remain in a closed state, which can effectively prevent the splashing of sand and improve the stability during operation.

[0049] The limiting assembly 103 moves to the maximum position to complete the descent and flip. When the lifting limiting rod 103a moves to the maximum distance, the arc surface at the top of one end of the extrusion plate 104c contacts the arc surface at the bottom of one end of the extrusion push block 104d. The extrusion plate 104c is squeezed by the extrusion push block 104d and drives the fixedly connected sandblasting gun 103d to slide downward along the slidingly connected lifting limiting column 103c through the L-shaped connecting rod 104b. The sandblasting gun 103d is limited in the lifting limiting groove 103b in the middle of the lifting limiting rod 103a, and keeps sliding vertically downward, pushing the locking piece 103h connected to the bottom of the sandblasting gun 103d to move downward. When the shrinking block 103h-1 moves downward, it is locked with the two sets of unlocking grooves 103h-1 inside the shrinking block 103h-1. The contraction spring 103h-3 fixedly connected to the inner wall of the lifting limit groove 103b pulls the fixedly connected locking block 103h-4 to move downward, and the locking block 103h-4 is inside the locking groove 103h-5 of the inner wall of the lifting limit groove 103b, so that the sandblasting gun 103d remains in a fixed state, and the arc surface at the bottom of one end of the locking block 103h-4 contacts with the arc surface adapted at the bottom of the locking groove 103h-5, and the contraction spring 103h-3 is squeezed by the arc surface at the bottom of the locking groove 103h-5 to deform and contract toward the inside of the unlocking groove 103h-2. When the locking block 103h-4 is completely contracted into the unlocking groove 103h-2, the sandblasting gun 103d is unlocked as a whole, and the sandblasting gun 103d loses its lock and moves to the bottom under the action of gravity;

[0050] When the flip gear 103f fixedly connected to one end of the telescopic sandblasting tube 103e moves downward, it contacts the meshing flip rack 103g, and rotates under the limit of the flip rack 103g in the fixed state. Under the limit of the length of the flip rack 103g, the flip rack 103g can drive the fixedly connected telescopic sandblasting tube 103e to complete a 180-degree rotation around the rotatably connected sandblasting gun 103d. After the telescopic sandblasting tube 103e completes the flipping, it moves to the bottom of the lifting limit groove 103b under the action of gravity. At this time, the sandblasting port of the telescopic sandblasting tube 103 is at the bottom of the furnace tube.

[0051] The limit assembly 103 returns to the initial position and is squeezed to complete the reset lock. The drive motor 102a is started again to drive the drive rod 102b to reverse, so that the trapezoidal sliding block 102c threadedly connected to the drive rod 102b slides in the direction of the initial position. When the inclined surface at one end of the squeezing plate 104c moves to contact the inclined surface adapted to the squeezing push plate 104a, the squeezing plate 104c is pushed by the inclined surface of the squeezing push plate 104a in the fixed state, and slides upward along the inclined surface of the squeezing push plate 104a. The contraction block 103h-1 fixedly connected to the squeezing plate 104c through the L-shaped connecting rod 104b drives the fixedly connected sandblasting gun 103d to slide upward on the slidingly connected lifting limit column 103c. At the same time, the lifting limit column 103c and the lifting limit slot 103c are locked. 3b is limited to prevent the extrusion plate 104c from being displaced toward the other end by the thrust of the extrusion push plate 104a. When the locking block 103h-4 inside the contraction block 103h-1 moves to a parallel state with the locking groove 103h-5, the elastic force converted after the contraction spring 103h-3 loses the extrusion force pushes the locking block 103h-4 to move away from the unlocking groove 103h-2 until it enters the locking groove 103h-5, completing the limit locking of the sandblasting gun 103d. At the same time, when the telescopic sandblasting tube 103e follows the upward movement, the flip gear 103f fixed at one end moves to contact with the meshing rack 103g, and is limited by the rack 103g to complete a 180-degree flip, so that the sandblasting port of the sandblasting tube 103 is at the top of the furnace tube again.

[0052] In summary, the present invention provides a protective adjustment unit, and the extrusion of the sliding assembly during movement enables the protective assembly to be opened and closed, and the unused part remains closed to prevent sand from splashing into the chute, thereby improving the operating stability of the equipment. When the sliding assembly moves to the end, the sandblasting gun moves to the bottom of the furnace tube by colliding and squeezing the adjustment assembly, and the limit assembly causes the sandblasting gun to flip when moving downward, ensuring that the furnace tube is sandblasted in all directions. The limitation of only being able to sandblast the furnace tube locally is avoided, and the treatment of the furnace tube surface is more comprehensive and uniform.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
