Description

Technical Field

[0001] This utility model relates to the technical field of wire reel cleaning equipment, and in particular to a descaling device for prestressed steel strand wire reels. Background Technology

[0002] After the prestressed steel strands are produced, they need to be stored using a wire reel. During long-term use, dust and impurities can easily adhere to the surface of the wire reel. If not cleaned in time, this can affect the winding of the prestressed steel strands by the wire reel.

[0003] Chinese Patent CN217569795U discloses a descaling device for prestressed steel strand pull drums, comprising a base plate and a descaling mechanism. The descaling mechanism, located on the upper side of the base plate, is used to remove dirt from the surface of the prestressed steel strand pull drum. The descaling mechanism includes an arc-shaped plate, with a pair of cylinders connected between the arc-shaped plate and the base plate. Multiple evenly distributed mounting parts are connected to the arc-shaped plate, and descaling friction parts are connected to the mounting parts. An anti-slip pad is provided on the lower surface of the base plate to increase the friction between the base plate and the ground, preventing the base plate from slipping when placed on the ground and ensuring the descaling effect of the descaling mechanism on the surface of the pull drum. The length of the base plate is greater than the length of the arc-shaped plate. This invention, through the design of the corresponding mechanism, can quickly descale the surface of the pull drum, improving the descaling efficiency of the pull drum, reducing the user's workload, and ensuring the normal winding and use of the pull drum for prestressed steel strands.

[0004] However, in the above-mentioned patent, the descaling mechanism is designed so that the spray holes are located on the arc-shaped plate. This makes it easy for the descaling liquid to become blocked at the spray holes under the influence of gravity, which is not conducive to the subsequent use of the spray holes and thus reduces the descaling efficiency of the wire reel. Utility Model Content

[0005] Based on the aforementioned technical problems, this utility model proposes a descaling device for prestressed steel strand puller drums.

[0006] This utility model proposes a descaling device for prestressed steel strand puller drum, including a base plate and a drum disposed on the upper surface of the base plate. The upper surface of the base plate is symmetrically distributed with a first side plate and a second side plate. A descaling mechanism is disposed between the first side plate and the second side plate. The descaling mechanism includes an arc-shaped descaling plate disposed between the first side plate and the second side plate.

[0010] The above technical solution facilitates the removal of scale from the surface of the winding drum as it rotates, while allowing the cleaning liquid to be discharged through the drop hole into the arc-shaped descaling plate.

[0014] Through the above technical solution, the rotation of the output shaft of the drive motor drives the screw connected to it to rotate, and the rotation of the screw drives the threaded block connected to it to move along the inner wall of the mounting groove.

[0015] Preferably, the support mechanism further includes a servo motor fixedly mounted on the upper surface of the second side plate, one end of the output shaft of the servo motor is fixedly sleeved with a rotating shaft, and one end of the rotating shaft is mounted on the inner wall of the slide rod through a bearing and fixedly sleeved with a circular rotating block.

[0016] Through the above technical solution, the rotation of the servo motor output shaft drives the rotating shaft connected to it to rotate, and the rotation of the rotating shaft drives the circular rotating block connected to it to rotate.

[0018] Through the above technical solution, the rotation of the circular rotating block drives the sliding rod to move through the inclined groove, thereby causing the locking block to move along the inner wall of the limiting sliding groove.

[0019] Preferably, a movable block is slidably sleeved on the surface of the slide rod, and the surface of the movable block is slidably engaged with the inner wall of the limiting groove. The two ends of the arc-shaped descaling plate are respectively fixedly connected to the opposite side surfaces of the threaded block and the movable block.

[0020] Through the above technical solution, the movement of the threaded block drives the movement of the arc-shaped descaling plate, and in turn drives the movement of the moving block on the slide rod.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Reference Figures 1-5 A descaling device for a prestressed steel strand puller drum includes a base plate 1 and a winding drum 2 disposed on the upper surface of the base plate 1. A first side plate 3 and a second side plate 4 are symmetrically distributed on the upper surface of the base plate 1. A descaling mechanism is disposed between the first side plate 3 and the second side plate 4. The descaling mechanism includes an arc-shaped descaling plate 5 disposed between the first side plate 3 and the second side plate 4.

[0032] To facilitate the fitting of the arc-shaped descaling plate 5 to the cable reel 2 and to facilitate drainage, the descaling mechanism also includes a groove 51 that fits against the surface of the cable reel 2. A drop hole 52 is fixedly installed on the inner wall of the groove 51 and extends to the outside of the arc-shaped descaling plate 5. As the cable reel 2 rotates, the arc-shaped descaling plate 5 wipes and descals the surface of the cable reel 2, while facilitating the discharge of the cleaning liquid through the drop hole 52 from the arc-shaped descaling plate 5.

[0033] In order to spray clean water on the surface of the spool 2, a distributor 53 is fixedly installed on one side of the spool 2. A nozzle 54 is installed at the outlet of the distributor 53. The inlet of the distributor 53 is connected to a water tank 55 through a pipe. Water in the water tank 55 is introduced into the distributor 53 by a water pump, so that the nozzle 54 sprays clean water on the surface of the spool 2.

[0034] By setting a nozzle 54 on one side of the winding drum 2, the nozzle 54 is prevented from being blocked by water after cleaning, and at the same time, it is easy to spray clean water onto the surface of the winding drum 2, which, together with the arc-shaped descaling plate 5, achieves the descaling effect.

[0035] The surface of the first side plate 3 is provided with a moving mechanism, which includes a mounting groove 6 opened on the surface of the first side plate 3 near the winding drum 2. A screw 61 is installed on the inner wall of the mounting groove 6 through a bearing. The rotation of the screw 61 drives the arc-shaped descaling plate 5 to move.

[0036] To drive the screw 61 to rotate, the moving mechanism also includes a drive motor 62 fixedly mounted on the upper surface of the first side plate 3. One end of the output shaft of the drive motor 62 extends into the first side plate 3 and is fixedly sleeved with the upper end of the screw 61. A threaded block 63 is threadedly sleeved on the surface of the screw 61. The surface of the threaded block 63 is slidably engaged with the inner wall of the mounting groove 6. The rotation of the output shaft of the drive motor 62 drives the screw 61 connected to it to rotate. The rotation of the screw 61 drives the threaded block 63 connected to it to move along the inner wall of the mounting groove 6.

[0037] The surface of the second side plate 4 is provided with a support mechanism, which includes a limiting groove 7 opened on the surface of the second side plate 4 near the winding drum 2, and a sliding rod 71 is fixedly connected to the inner wall of the limiting groove 7.

[0038] In order to move the arc-shaped descaling plate 5 smoothly, a moving block 79 is slidably sleeved on the surface of the slide rod 71. The surface of the moving block 79 is slidably engaged with the inner wall of the limiting groove 7. The two ends of the arc-shaped descaling plate 5 are fixedly connected to the opposite side surfaces of the threaded block 63 and the moving block 79, respectively. The movement of the threaded block 63 drives the arc-shaped descaling plate 5 to move, thereby driving the moving block 79 to move along the surface of the slide rod 71, so that the arc-shaped descaling plate 5 moves up and down smoothly.

[0039] To support the movement of the arc-shaped descaling plate 5, the support mechanism also includes a servo motor 72 fixedly mounted on the upper surface of the second side plate 4. One end of the output shaft of the servo motor 72 is fixedly sleeved with a rotating shaft 73. One end of the rotating shaft 73 is mounted on the inner wall of the slide rod 71 via a bearing and fixedly sleeved with a circular rotating block 74. The surface of the circular rotating block 74 has inclined grooves 75 arranged in a ring array. A sliding rod 76 is slidably engaged with the inner wall of the inclined groove 75. A locking block 77 is fixedly connected to the lower end of the sliding rod 76. Limiting grooves 78 are arranged in a ring array on the surface of the slide rod 71. The surface of the locking block 77 is aligned with the limiting grooves 78. The inner wall of the sliding groove 78 is slidably engaged, and the surface of the sliding rod 71 is slidably sleeved with the moving block 79. The surface of the moving block 79 is slidably engaged with the inner wall of the limiting groove 7. When the movement of the moving block 79 causes the arc-shaped descaling plate 5 to contact the winding drum 2, the rotation of the output shaft of the servo motor 72 drives the rotating shaft 73 connected to it to rotate. The rotation of the rotating shaft 73 drives the circular rotating block 74 connected to it to rotate. The rotation of the circular rotating block 74 drives the sliding rod 71 to move through the inclined groove 75, thereby causing the locking block 77 to move out along the inner wall of the limiting groove 78 and slide into contact with the bottom of the moving block 79, thereby providing support.

[0040] By setting up a moving mechanism and a supporting mechanism, the rotation of the output shaft of the drive motor 62 drives the arc-shaped descaling plate 5 to contact and adhere to the surface of the winding drum 2. When the arc-shaped descaling plate 5 contacts the winding drum 2, the rotation of the output shaft of the servo motor 72 drives the locking block 77 to move out of the slide rod 71 to support the arc-shaped descaling plate 5, thereby facilitating descaling.

[0041] Working principle: When in use, the clean water in the water tank 55 is introduced into the distributor 53 by the water pump, and the clean water in the distributor 53 is sprayed onto the surface of the winding drum 2 by the nozzle 54. At the same time, the drive motor 62 is started. The rotation of the output shaft of the drive motor 62 drives the screw 61 in the first side plate 3 to rotate. The rotation of the screw 61 drives the threaded block 63 to move upward along the inner wall of the mounting groove 6. The upward movement of the threaded block 63 drives the arc-shaped descaling plate 5 to move upward. At the same time, it drives the moving block 79 to move upward along the inner wall of the limiting groove 7 and the surface of the sliding rod 71, so that the upper surface of the arc-shaped descaling plate 5 is in contact with the surface of the winding drum.

[0042] Then, the servo motor 72 is started. The rotation of the output shaft of the servo motor 72 drives the rotating shaft 73 connected to it to rotate. The rotation of the rotating shaft 73 drives the circular rotating block 74 connected to it to rotate. The rotation of the circular rotating block 74 drives the slide rod 71 to move through the inclined groove 75, thereby driving the locking block 77 to move out along the inner wall of the limiting slide groove 78, so that the locking block 77 slides in contact with the bottom of the moving block 79.

[0043] Then, as the winding drum 2 rotates, the arc-shaped descaling plate 5 cleans and descals the surface of the winding drum 2 that is wet.

[0044] 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.
