[0002] Elevator counterweight is an important component of the elevator system. It is usually made of cast iron or other heavy objects and is connected to the elevator car through steel ropes and pulleys. It is used to balance the traction and braking forces of the elevator, reduce motor energy consumption, and improve the stability and safety of elevator operation.

[0003] During the production process of elevator counterweights, semi-finished products usually need to be immersed in a cleaning tank. The cleaning fluid removes impurities such as oil, metal debris, and dust from the surface of the semi-finished products, providing a clean base for subsequent surface treatment (such as painting, galvanizing, etc.), thereby improving product quality and durability.

[0004] In the prior art, when cleaning the elevator counterweight, the workpiece is usually placed directly in a cleaning tank, and the cleaning liquid is allowed to contact the surface of the elevator counterweight by soaking. However, due to the poor fluidity of the cleaning liquid in the cleaning tank, it is necessary to increase the soaking time to ensure the cleaning effect. In addition, during the process of salvaging the cleaned workpiece from the cleaning tank, some of the cleaning liquid attached to the surface of the workpiece will fall onto the equipment and the ground around the cleaning device, causing environmental pollution.

[0005] Therefore, it is necessary to improve the elevator counterweight surface cleaning device in the prior art. Utility Model Content

[0034] The following embodiments are used to further describe the specific embodiments of the present invention in conjunction with the accompanying drawings and examples. The following embodiments are only used to more clearly illustrate the technical solutions of the present invention and are not intended to limit the scope of protection of the present invention.

[0035] like Figures 1-10 As shown, the cleaning device for surface treatment of traction elevator counterweight blocks of the utility model comprises:

[0036] Cleaning pool 1, the top of the cleaning pool 1 is open;

[0037] A storage rack 2 is used to store a plurality of workpieces 3 horizontally and at intervals along a vertical direction;

[0038] The movable assembly 4 includes a translation frame 41, a driving mechanism, and a movable frame 44 arranged in sequence along the vertical direction. The movable frame 44 is detachably connected to the storage frame 2. The driving mechanism drives the movable frame 44 to move and rotate in the vertical direction. The rotation axis of the movable frame 44 extends in the vertical direction.

[0039] The translation assembly 5 drives the translation frame 41 to move in the horizontal direction;

[0040] The translation assembly 5 and the driving mechanism cooperate with each other to drive the storage rack 2 to move into the cleaning tank 1 , directly above the cleaning tank 1 and to one side of the cleaning tank 1 .

[0041] In the initial stage of use of the device, the storage rack 2 is separated from the movable rack 44, and multiple workpieces 3 are stored on the storage rack 2. In the storage state, the workpieces 3 are spaced apart in the vertical direction and are restricted on the storage rack 2 and cannot be separated from the storage rack 2. Through the cooperation of the driving mechanism and the translation component 5, the movable rack 44 is adjusted to one side of the cleaning tank 1, and then the storage rack 2 is connected to the movable rack 44.

[0042] After the connection is completed, the driving mechanism drives the storage rack 2 to rise to the upper side of the cleaning tank 1, and adjusts the position of the translation rack 41 through the translation component 5, so that the movable component 4 drives the storage rack 2 to move to directly above the cleaning tank 1; then, the driving mechanism drives the storage rack 2 to descend, so that the storage rack 2 and the workpiece 3 on the storage rack 2 are immersed in the cleaning liquid of the cleaning tank 1, and the driving mechanism drives the storage rack 2 to rotate through the movable rack 44, prompting the cleaning liquid in the cleaning tank 1 to flow, thereby enhancing the contact between the cleaning liquid and the workpiece 3, so that the cleaning liquid can quickly clean the surface of the workpiece 3.

[0043] After cleaning is completed, the driving mechanism first drives the storage rack 2 to rise above the cleaning tank 1, and then the translation component 5 drives the translation rack 41 to move horizontally, adjusts the position of the movable component 4, storage rack 2 and workpiece 3, so that the storage rack 2 and workpiece 3 are located above the side of the cleaning tank 1, and then the driving mechanism drives the movable rack 44 to descend, separates the storage rack 2 from the movable rack 44, and the workpiece 3 that has been cleaned on the storage rack 2 can be easily taken out.

[0044] Since the storage rack 2 can store multiple workpieces 3 at a time, and during the cleaning process, the storage rack 2 can be driven to rotate in the vertical direction by the driving mechanism, the fluidity of the cleaning liquid is increased, so that the cleaning liquid can quickly contact multiple workpieces 3, thereby greatly improving the cleaning efficiency.

[0045] A further improvement is that it also includes a guide component 6, which is used to move upward to the top of the cleaning pool 1 and allow the cleaning liquid thrown out by the rotating storage rack 2 to flow back into the cleaning pool 1; the guide component 6 includes a guide cylinder 61 and a telescopic unit 62 that drives the guide cylinder 61 to move between the inside of the cleaning pool 1 and directly above the cleaning pool 1.

[0046] The guide cylinder 61 extends in the vertical direction. In the initial state, the telescopic unit 62 drives the guide cylinder 61 to descend into the cleaning tank 1. When the workpiece 3 is immersed in the cleaning tank 1 and the cleaning is completed, the driving mechanism drives the storage rack 2 to move upward to the top of the cleaning tank 1. The telescopic unit 62 drives the guide cylinder 61 to move to the top of the cleaning tank 1, so that the storage rack 2 is located on the inner side of the guide cylinder 61, and the projection of the guide cylinder 61 on the horizontal plane is located at the projection of the top opening of the cleaning tank 1 on the horizontal plane. At this time, the driving mechanism drives the storage rack 2 to rotate at high speed. The centrifugal force generated during the operation of the cleaning rack 2 and the workpiece 3 throws out the cleaning liquid attached to the storage rack 2 and the surface of the workpiece 3. Part of the thrown cleaning liquid falls directly into the cleaning tank 1, while the other part collides with the inner wall of the guide cylinder 61 and falls downward along the inner wall of the guide cylinder 61 into the cleaning tank 1. In this way, while drying the storage rack 2 and the workpiece 3, it avoids the cleaning liquid from falling outside the cleaning tank 1 and causing environmental pollution. In addition, the fallen cleaning liquid is collected by the cleaning tank 1, which is convenient for subsequent cleaning processing, thereby reducing the use of cleaning liquid and reducing cleaning costs.

[0047] After the cleaning liquid is dried, the telescopic unit 62 drives the guide cylinder 61 down into the cleaning pool 1, so that the guide cylinder 61 is located directly below the movable component 4, making it convenient for the translation component 5 to drive the movable component 4 and the dried storage rack 2 and workpiece 3 to translate.

[0048] The specific structure of the cleaning pool 1 of the utility model is as follows Figure 1-Figure 4 As shown, the cleaning tank 1 is cylindrical, with a drain pipe 11 connected to its bottom. The drain pipe 11 is connected to a drain valve 12. After a certain period of use, the cleaning effect of the cleaning liquid decreases significantly. At this time, the drain valve 12 is opened to conveniently drain the used cleaning liquid in the cleaning tank 1. A first flange 13 is provided on the top circumferential outer edge of the cleaning tank 1. The first flange 13 is provided with a guide hole 131 extending in the vertical direction.

[0049] In the guide assembly 6, the guide tube 61 is coaxial with the cleaning tank 1. Horizontal outer convex plates 64 are integrally connected to the top circumferential outer edge of the guide tube 61 on both sides. Guide rods 63 extending in the vertical direction are fixed below the outer convex plates 64. The guide rods 63 slide through the inner sides of the guide holes 131 in a one-to-one correspondence. The telescopic unit 62 is an electric push rod extending vertically upward. The bottom of the housing is fixed to the bottom surface, and the movable rod is fixedly connected to the outer convex plates 64. The telescopic unit 62 acts on the outer convex plates 64, and the sliding fit of the guide rods 63 and the guide holes 131 drive the guide tube 61 to move stably in the vertical direction. After cleaning is completed, the guide tube 61 can rise to directly above the cleaning tank 1 to surround the storage rack 2. This facilitates the rotation of the storage rack 2 and the workpiece 3, blocking the spurted cleaning fluid and guiding it downward into the cleaning tank 1. After the cleaning fluid is spun off, the guide tube 61 descends into the cleaning tank 1, allowing the translation assembly 5 to drive the storage rack 2 horizontally.

[0050] The translation assembly 5 of the present invention has a specific structure as follows Figure 5 and Figure 6 As shown, the translation assembly 5 includes a frame 51, which includes a base 511 fixed horizontally on the ground and distributed on both sides of the cleaning pool 1, and two pillars 512 extending in the vertical direction are fixed above the base 511. On the same base 511, the distribution direction of the two pillars 512 is perpendicular to the distribution direction of the base 511, and the tops of the two pillars 512 are fixedly connected by a first crossbeam 513, and the two first crossbeams 513 are fixedly connected by two second crossbeams 514. The first crossbeam 513 and the second crossbeam 514 are both horizontally arranged; the translation assembly 5 also includes a translation motor 52 and a shaft sleeve 57 respectively fixed below the two first crossbeams 513, and a crossbar 521 with two ends fixedly connected to the two pillars 512 is also fixed below the translation motor 52, and the output end of the translation motor 52 is fixedly connected to the coaxial centerline with a screw rod 53, and the screw rod 5 The axial direction is consistent with the length direction of the second crossbeam 514. The screw rod 53 is threadedly connected to the translation block 54 and its end is rotated on the inner side of the shaft sleeve 57. A connecting strip 541 extending along the length direction of the first crossbeam 513 is fixed above the translation block 54. Both sides of the connecting strip 541 are fixedly connected to the translation frame 55. The translation frames 55 are sleeved on the outside of the second crossbeam 514 in a one-to-one manner. The cross section of the second crossbeam 514 is square. The cross sections of the circumferential inner wall and the circumferential outer edge of the translation frame 55 are both square and have the same center position. Openings are provided on the four side walls of the translation frame 55. A guide wheel 56 is provided on the inside of the opening. The guide wheel 56 rotates around its own axis in the opening, and the rotation axis is parallel to the width direction of the corresponding side wall of the translation frame 55. The wheel surface of the guide wheel 56 is in contact with the outer wall of the second crossbeam 514. The translation block 54 is fixedly connected to the translation frame 41.

[0051] After adopting the above structure, the translation motor 52 is started, driving the screw rod 53 to rotate, and the screw rod 53 acts on the translation block 54, so that the translation block 54 moves axially along the screw rod 53. Since the translation frame 55 is mounted on the second crossbeam 514, and the guide wheels 56 on the four side walls of the translation frame 55 are respectively attached to the four side walls of the second crossbeam 514, the translation block 54 and the connecting bar 541 can move smoothly along the axial direction of the screw rod 53, thereby realizing the smooth movement of the translation frame 41.

[0052] A further improvement is that the storage rack 2 includes a base frame 21, a top frame 22 arranged directly above the base frame 21, a horizontal bracket 23 distributed between the base frame 21 and the top frame 22 in the vertical direction, and a side frame 24 distributed along the circumferential direction on the outer edge of the bracket 23 and connected to the base frame 21 and the top frame 22 at both ends. The two ends of at least one of the side frames 24 are detachably connected to the base frame 21 and the top frame 22, and the top surface of the bracket 23 is protruding with a roller 25 for supporting the workpiece 3; the base frame 21 and the top frame 22 are provided with sockets 28 on the two opposite sides, and the side frames 24 detachably provided on the base frame 21 and the top frame 22 are adjustable in length and are respectively plugged into the sockets 28 of the base frame 21 and the top frame 22 at both ends. The side frames 24 are also provided with limiting protrusions 243 adjacent to the two ends.

[0053] The specific structure of the storage rack 2 is as follows Figure 9 and Figure 10 As shown, the bottom frame 21 and the top frame 22 of the storage rack 2 are both rectangular frame structures as a whole, and a plurality of brackets 23 are arranged between the bottom frame 21 and the top frame 22 along the distribution direction of the two. The brackets 23 are used to support the workpiece 3, and the interval between adjacent brackets 23 is greater than the width of the workpiece 3 to ensure that the cleaning liquid can contact the top surface of the workpiece 3 during the cleaning process; the bracket 23 is composed of a plurality of long rectangular frames distributed side by side, and a plurality of rollers 25 rotating around their own axis are arranged on the inner side of the long rectangular frame. The rotation axis of the roller 25 is consistent with the length direction of the long rectangular frame, and the wheel surface of the roller 25 protrudes from the top surface of the long rectangular frame, so that the roller 25 contacts the bottom surface of the workpiece 3 and supports the workpiece 3, and reduces the contact area with the bottom surface of the workpiece 3, which facilitates the contact between the cleaning liquid and the workpiece 3 and ensures the cleaning effect. In addition, the rolling of the roller 25 facilitates the translation and placement of the workpiece 3.

[0054] A plurality of side frames 24 are provided on the outside of the bracket 23, and the two ends of the side frames 24 are fixedly connected to the base frame 21 and the top frame 22, so as to surround the workpiece 3 on the bracket 23 and prevent the workpiece 3 from detaching from the bracket 23 during the movement and rotation of the storage rack 2. In this way, the workpiece 3 is limited, and at least one of the side frames 24 is detachably connected to the base frame 21 and the top frame 22, thereby facilitating the storage and retrieval of the workpiece 3.

[0055] Specifically, the side frames 24 located at the ends of the bottom frame 21 and the top frame 22 are detachably connected to the bottom frame 21 and the top frame 22, thereby facilitating the storage and retrieval of the workpiece 3 from the end positions of the storage rack 2. Both ends of the bottom frame 21 and the top frame 22 are provided with a socket 28, which is a through hole extending along the thickness direction of the two. The side frames 24 at both end positions include a central axis 241, and both ends of the central axis 241 have a coaxial threaded section. The threaded section is threadedly connected to a threaded end sleeve 242. The threaded end sleeve 242 is threadedly connected to an insert rod 244 through a limiting protrusion 243. The insert rod 244, the limiting protrusion 243 and the threaded end sleeve 242 are coaxial. The insert rod 244 is plugged into the socket 28, and the outer diameter of the limiting protrusion 243 is larger than the inner diameter of the socket 28.

[0056] With the above structure, the length of the side frame 24 composed of the central shaft 241, the threaded end sleeve 242, the limiting protruding ring 243 and the insertion rod 244 can be adjusted. The threaded end sleeve 242 is rotated at the end of the central shaft 241, and the insertion rod 244 is moved closer to or away from the central shaft 241 according to the rotation direction, thereby shortening or lengthening the length of the side frame 24. When the side frame 24 is installed between the bottom frame 21 and the top frame 22, the length of the side frame 24 is first shortened to make it smaller than the bottom frame 21 and the top frame 22. After the top frame 22 is away, align the center axis 241 with the socket 28, rotate the threaded end sleeve 242, so that the insertion rod 244 is inserted into the socket 28, and the two limiting protrusions 243 are respectively abutted on the bottom frame 21 and the top frame 22, thereby completing the installation; and rotate the threaded end sleeve 242 to reduce the length of the side frame 24, so that the insertion rod 244 is disengaged from the socket 28, and the side frame 24 can be removed and separated from between the bottom frame 21 and the top frame 22, so that it is convenient to take and place the workpiece 3 on the bracket 23.

[0057] A further improvement is that the storage rack 2 and the movable rack 44 are detachably connected via a screw rod 26 and a nut 27 that are threadedly matched.

[0058] Specifically, the axial direction of the screw 26 is parallel to the distribution direction of the base frame 21 and the top frame 22 and is integrally formed on the top surface of the top frame 22. Four screws 26 and nuts 27 are provided and distributed in a circular array. The movable frame 44 is a downward barrel-shaped structure, and a second flange 442 is provided on the circumferential outer edge of the bottom. The screw 26 is passed through the second flange 442, and the bottom surface of the nut 27 abuts against the top surface of the second flange 442. In this way, a quick and detachable connection between the movable frame 44 and the storage frame 2 is achieved. On the one hand, it is convenient to remove the storage frame 2 from the movable frame 44 before cleaning, and then load multiple workpieces 3 on the storage frame 2. On the other hand, it is convenient to remove the storage frame 2 from the movable frame 44 after cleaning, and take out the workpiece 3 on the storage frame 2 for subsequent processing.

[0059] In order to drive the movable frame 44 to move up and down and rotate, the driving mechanism of the present invention includes a lifting unit 42 for driving the movable frame 44 to move up and down and a rotating unit 43 for driving the movable frame 44 to rotate.

[0060] A further improvement is that the rotating unit 43 includes a rotating motor 431 fixed on the translation frame 41, a driving wheel 432 connected to the output end of the rotating motor 431 coaxially, a driven wheel 433 connected to the movable frame 44 coaxially and rotating around its own axis on the translation frame 41, and a synchronous belt 434 that is transmission-connected to the driving wheel 432 and the driven wheel 433; the driven wheel 433 is annular, and the lifting unit 42 includes a winding motor 421 fixed on the translation frame 41, a winding drum 422 connected to the output shaft of the winding motor 421 coaxially, and a winding rope 423 passed through the inner side of the driven wheel 433 and connected at both ends to the winding drum 422 and the movable frame 44 respectively; an eccentric rod 435 and an eccentric hole 441 are provided between the driven wheel 433 and the movable frame 44 to slide in the vertical direction and deviate from the rotation axis of the movable frame 44.

[0061] Specifically, such as Figure 7 and Figure 8 As shown, in the movable component 4, the translation frame 41 is a translation plate, which is welded and fixed directly below the translation block 54. The lifting unit 42 also includes a fixed plate 425 and a support sleeve 424. The fixed plate 425 is fixed to the bottom of the translation plate through the horizontally distributed support sleeve 424 and the winding motor 421. The winding drum 422 is horizontally arranged, one end of which is connected to the output end of the winding motor 421 coaxially, and the other end rotates around its own axis on the support sleeve 424. The fixed plate 425 is provided with a through hole for the transmission of the winding rope 423.

[0062] The rotating unit 43 also includes a bearing 438. The outer ring of the bearing 438 is fixed below the fixed plate 425, and the inner ring is fixed coaxially above the driven pulley 433. The rotating motor 431 is fixed below the translation frame 41, and its output end is fixedly connected downwardly and coaxially to the driving pulley 432. The driving pulley 432 is connected to the driven pulley 433 via a synchronous belt 434. An eccentric hole 441 is a through hole extending in the vertical direction and is provided at the top of the movable frame 44. A disc 436 is fixedly connected coaxially below the driven pulley 433. The disc 436 has a center hole coaxially therewith. An eccentric rod 435 is fixed below the disc 436, which corresponds to and slidably engages with the eccentric hole 441. The eccentric rod 435 is located inside the movable frame 44, and its bottom end is fixedly connected via a retaining ring 437. One end of the winding rope 423 away from the winding drum 422 is sequentially passed through the through hole, the inner side of the bearing 438 and the inner side of the driven wheel 433, and the center hole is connected to the movable frame 44.

[0063] After adopting the above structure, when the lifting unit 42 is in operation, the winding motor 421 is started, driving the winding drum 422 to rotate under the support of the support sleeve 424, so that the winding drum 422 reels or unwinds the winding rope 423, and the end of the winding rope 423 away from the winding drum 422 passes through the through hole, bearing 438, driven wheel 433 and center hole in sequence and is connected to the movable frame 44. Under the sliding cooperation of the eccentric rod 435 and the eccentric hole 441, the movable frame 44 drives the storage rack 2 to move stably up and down in the vertical direction.

[0064] When the rotating unit 43 is running, the rotating motor 431 starts, driving the driving wheel 432 to rotate, and acts on the driven wheel 433 through the synchronous belt 434, so that the driven wheel 433 drives the disc 436 below to rotate, and the eccentric rod 435 below the disc 436 acts on the inner wall of the eccentric hole 441, so that the movable frame 44 rotates around its own axis.

[0065] In this way, the lifting unit 42 and the rotating unit 43 operate relatively independently without interfering with each other. The operation of one will not change the position and state of the other, thereby ensuring that the driving mechanism can drive the movable frame 44 to perform stable lifting and rotating movements.

[0066] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
