Description

Technical Field

[0001] This utility model relates to the field of painting and hoisting tools, specifically to a water-soluble paint coating device for support rollers. Background Technology

[0002] In the field of engineering machinery manufacturing, track rollers are the core load-bearing components of tracked equipment, and their surface coating process directly affects their corrosion resistance and service life. Traditional track roller coating mostly adopts fixed suspension clamps for immersion coating, which has the following technical problems: (1) The clamp structure is fixed, and the clamping distance and angle cannot be flexibly adjusted. It is difficult to be compatible with track rollers of different lengths and apertures, and frequent tooling changes are required, resulting in low production efficiency; (2) During the coating process, the track roller is prone to displacement due to vibration or paint resistance, resulting in uneven coating thickness or even peeling; (3) Loading and unloading rely on manual operation, especially after coating, the workpiece needs to be manually disassembled, resulting in poor work continuity and safety hazards. Therefore, it is urgent to develop a coating device that can be adaptively adjusted, has stable clamping, and can be quickly changed to meet the high-efficiency coating needs of mass production and multi-specification track rollers. Utility Model Content

[0003] I. Technical problems to be solved

[0004] The purpose of this utility model is to provide a water-soluble paint coating device for support rollers, which provides an adaptive, stable clamping and quick-change coating device.

[0005] II. Technical Solution

[0006] This utility model is achieved through the following technical solution:

[0007] This utility model proposes a water-soluble paint coating device for support rollers, including a hanger. The hanger includes a hook and a connecting block connected below the hook. Two symmetrical connecting rods are rotatably connected to the connecting block via a rotating shaft. An adjusting rod is rotatably connected to the lower end of the connecting rod. A longitudinal rod is detachably connected to the lower part of the adjusting rod via a matching bolt and nut. A transverse shaft is fixedly connected to the opposite side of each of the two longitudinal rods. Multiple adjusting holes are equidistantly opened on the surface of the adjusting rod along its length direction. The two adjusting rods are rotatably connected to each other by a pin passing through the adjusting holes.

[0008] Furthermore, it also includes a retaining element, which includes a frame and four insert rods connected to the side of the frame; when the horizontal axis is in a horizontal position, the four insert rods can be inserted into four different adjustment holes surrounding the pin shaft respectively.

[0009] Furthermore, it also includes a tension spring, the two ends of which are hooked between the adjustment holes on the outer sides of the two adjustment rods.

[0010] Furthermore, the pin has a through hole along the axial direction, a longitudinal beam is provided in the middle of the frame, and a through hole coaxial with the through hole is provided in the middle of the longitudinal beam. The fixing member also includes a locking block. The locking block has protruding protrusions on both sides that can clamp the sides of the longitudinal beam. Bolts are fixedly connected to the surface of the locking block between the two protrusions. The bolts pass through the through hole and the through hole in sequence and are locked by the locking block with the matching nuts.

[0011] Furthermore, the pin has external threads at both ends and threaded sleeves that are threadedly engaged, with the two threaded sleeves respectively positioned on both sides of the adjusting rod.

[0012] Furthermore, the bottom end of the adjusting rod and the top end of the longitudinal rod are respectively machined with coaxial matching positioning holes; a number of wedge blocks are evenly distributed on the contact end face of the adjusting rod and the longitudinal rod along the circumference of the positioning holes, and the two sets of wedge blocks are staggered and can mesh and insert into each other; wherein, the wedge blocks on the end face of the adjusting rod can be embedded into the gap space formed by adjacent wedge blocks on the end face of the longitudinal rod to achieve circumferential positioning.

[0013] Furthermore, it also includes a hanging platform, with multiple hangers evenly distributed around the circumference and connected to the hanging platform.

[0014] III. Beneficial Effects

[0015] Compared with the prior art, this utility model has the following advantages:

[0016] 1. The adjusting rod is equipped with multiple sets of equidistant adjusting holes. Different hole positions can be selected and connected by the pin shaft, which can quickly adjust the angle of the lower longitudinal rod to adapt to support rollers of different lengths. The longitudinal rod and the adjusting rod are positioned by wedge block engagement and bolt positioning to achieve circumferential angle fine adjustment, ensuring that the horizontal shaft is accurately inserted into the holes at both ends of the support roller and avoiding eccentric swaying.

[0017] 2. The four insert rods of the retaining component are inserted into the adjustment holes to form four-point limiting. Combined with the locking block bolts and the through-hole of the pin shaft, the angle of the adjustment rods is locked in a double manner to prevent them from loosening due to external force during painting. For the same batch of support rollers, the pre-made matching retaining components are used. The position of the insert rod holes and the adjustment hole group are pre-calibrated to achieve plug-and-play and eliminate the need for repeated adjustments.

[0018] 3. The tension spring traction adjustment rod automatically resets. After the coating is completed, the fixing part can be removed and the hook will automatically disengage, realizing unloading of the support roller without interference. Pressing down the adjustment rod will trigger the horizontal shaft alignment insertion. With the insertion and removal of the fixing part, the time for changing the support roller is shortened.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] A water-soluble paint coating apparatus for track rollers, please refer to [link / reference]. Figure 1 It includes a hanger 2 and a hanging plate 1. Multiple hangers 2 are evenly distributed around the hanging plate 1. Each hanger 2 includes a hook 201 and a connecting block 202 connected below the hook 201. The hook 201 is connected to the hanging plate 1. Each hanger 2 suspends a support roller 13. The support roller 13 is moved and immersed in water-based paint by moving or rotating the hanging plate 1.

[0026] In this embodiment, two symmetrical connecting rods 4 are coaxially rotatably connected to the connecting block 202 via a rotating shaft 3. An adjusting rod 5 is rotatably connected to the lower end of the connecting rod 4. A longitudinal rod 6 is detachably connected to the lower part of the adjusting rod 5 via a matching bolt and nut. A transverse shaft 7 is fixedly connected to the opposite side of the two longitudinal rods 6. Multiple adjusting holes 501 are equidistantly opened on the surface of the adjusting rod 5 along its length direction. The two adjusting rods 5 are connected to each other by a pin 8 passing through the adjusting holes 501 to achieve relative rotational connection.

[0027] It also includes a retaining member 10, which includes a frame 1001 and four insert rods 1002 connected to the side of the frame 1001; when the horizontal axis is in a horizontal position, the four insert rods 1002 can be inserted into or removed from four different adjustment holes 501 surrounding the pin 8 respectively.

[0028] In use, lift the adjusting rod 5 to expand the space between the two horizontal shafts 7 and place the support roller 13 under the hanger 2; after releasing the adjusting rod 5, the two horizontal shafts 7 rotate towards each other to a horizontal position, and the ends of the horizontal shafts 7 are inserted into the holes on both sides of the support roller 13. At this time, the fixing member 10 is oriented towards the adjusting rod 5, and the four inserts 1002 of the fixing member 10 are respectively inserted into the four adjusting holes 501. The fixing member 10 locks the angle and position of the two adjusting rods 5, and the hanging plate 1 drives the hanger 2 to move, thereby moving the support roller 13 into the water-based paint for coating.

[0029] In this invention, different positions of the adjustment holes 501 can be selected on the two adjustment rods 5 to make them coaxial and opposite each other. The two adjustment rods 5 are connected by a pin 8 passing through the adjustment holes 501. The higher the selected adjustment hole 501 is, the greater the opening angle of the lower ends of the two adjustment rods 5, and the longer the support roller 13 can be lifted. After the adjustment holes 501 are selected and connected by the pin 8, the bolts and nuts between the longitudinal rod 6 and the adjustment rod 5 are loosened and the longitudinal rod 6 is rotated until the horizontal shaft 7 is in a horizontal position. At this point, the four insertion rods 1002 can be inserted into the four different adjustment holes 501 surrounding the pin 8, and the end of the horizontal shaft 7 can be inserted into the holes at both ends of the support roller 13. The specifications of the retaining component 10 are prefabricated according to the size of the support roller 13. When painting support rollers 13 of the same specification in batches, there is no need to replace the retaining component 10, which improves production efficiency.

[0030] In addition, a tension spring 9 is included, with its two ends hooked between the two adjusting rods 5 located in the adjusting holes 501 on the outer side. During use, after one support roller 13 is painted, the retaining member 10 is removed. Under the tension of the tension spring 9, the adjusting rod 5 is lifted upwards, and the end of the horizontal shaft 7 moves out of the holes at both ends of the support roller 13, thus automatically releasing the support roller 13 from its suspended state. When replacing the next support roller 13, the two adjusting rods 5 are pressed down, causing the end of the horizontal shaft 7 to extend into the holes at both ends of the support roller 13. Then, the retaining member 10 is oriented towards the adjusting rod 5, allowing the insertion rod 1002 to be inserted into the adjusting hole 501. After the retaining member 10 fixes the position of the adjusting rod 5, the next support roller 13 can be hoisted and painted. Therefore, by incorporating the tension spring 9, the efficiency of connecting and hoisting the support roller 13 is improved.

[0031] In one embodiment of this utility model, the pin 8 has a through hole 801 along the axial direction, and a longitudinal beam 10011 is provided in the middle of the frame 1001. The longitudinal beam 10011 has a through hole 100111 coaxial with the through hole 801 in the middle. The fixing member 10 also includes a locking block 1003. The locking block 1003 has protruding parts 10031 on both sides that can be clamped on both sides of the longitudinal beam 10011. A bolt is fixedly connected to the surface of the locking block 1003 between the two protruding parts 10031. The bolt passes through the through hole 100111 and the through hole 801 in sequence and is locked by the locking block 1003 by the nut that cooperates with it. In this embodiment, after the retaining member 10 is inserted into the adjusting hole 501, the through hole 100111 and the through hole 801 are exactly coaxially opposite. The bolt on the locking block 1003 is inserted into the through hole 100111. After the bolt passes through the through hole 801, the nut is tightened. The protrusions 10031 on both sides of the locking block 1003 are limited to both sides of the longitudinal beam 10011, which improves the stability of the frame 1001 and ensures that the retaining member 10 will not loosen.

[0032] The connection structure of the pin 8 is shown in the figure. The pin 8 has external threads at both ends and threaded sleeves 14 are threadedly engaged. The two threaded sleeves 14 are respectively located on both sides of the adjusting rod 5. The pin 8 is detachable, which facilitates the quick assembly of the pin 8 when different adjusting holes 501 are selected, so as to cooperate with the lifting and painting of support rollers 13 of different sizes.

[0033] Furthermore, in this embodiment, the bottom end of the adjusting rod 5 and the top end of the longitudinal rod 6 are respectively machined with coaxially matched positioning holes 11; a plurality of wedge blocks 12 are evenly distributed along the circumference of the positioning holes 11 on the contact end faces of the adjusting rod 5 and the longitudinal rod 6, and the two sets of wedge blocks 12 are staggered and can be interlocked; wherein, the wedge blocks 12 on the end face of the adjusting rod 5 can be embedded into the gap space formed by adjacent wedge blocks 12 on the end face of the longitudinal rod 6 to achieve circumferential positioning. By interlocking the two sets of wedge blocks 12, the position of the longitudinal rod 6 can be locked after selecting the appropriate angle between the longitudinal rod 6 and the adjusting rod 5, and the nut can be tightened after the bolt passes through the positioning hole 11, which improves the stability of the longitudinal rod 6.

[0034] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Various modifications and improvements made to the technical solutions of the present invention by those skilled in the art without departing from the design concept of the present invention should fall within the protection scope of the present invention.
