DETAILED DESCRIPTION

[0038] 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.

[0039] First embodiment

[0040] like Figures 1-11 As shown, the cleaning device of the first embodiment of the present invention includes:

[0041] The frame 1 includes a horizontal beam 11 extending in the horizontal direction;

[0042] The cleaning assembly 2 includes a plurality of cleaning pools 21 distributed in sequence on one side of the frame 1 along a length direction parallel to the crossbeam 11 and with open tops;

[0043] The storage rack 3 includes a basket-like frame 31 and extension rods 32 provided on both sides of the frame 31. The frame 31 is used for temporarily storing metal products and its horizontal dimension is smaller than that of the cleaning tank 21.

[0044] The traveling assembly 4 includes a traveling frame 41 that moves on the crossbeam 11 and a driving unit 42 that drives the traveling frame 41 to move along the length direction of the crossbeam 11;

[0045] The lifting assembly 5 includes a slide rail 51 extending in a vertical direction and fixedly connected to the traveling frame 41, a lifting beam 52 moving in a vertical direction on the slide rail 51, a power unit 53 driving the lifting beam 52, and support members 54 provided below both ends of the lifting beam 52 and used to support the extension rod 32;

[0046] In use, the support member 54 , the power unit 53 and the travel assembly 4 cooperate with each other to immerse the metal products on the storage rack 3 in each cleaning tank 21 in turn.

[0047] When the device is in use, a batch of metal products are placed on the inner side of the frame 31 of the storage rack 3, the position of the storage rack 3 is adjusted, and the cleaning liquid required for cleaning the metal products is injected into each cleaning tank 21. The walking component 4 is operated to control the walking frame 41 to move on the crossbeam 11, and the horizontal position of the lifting beam 52 in the lifting component 5 is adjusted so that the support members 54 at both ends of the lifting beam 52 move their horizontal plane projection positions. After the horizontal plane projection positions are consistent with the projection positions of the extension rods 32 on both sides of the outside of the frame 31, the power unit 53 controls the lifting beam 52 to move upward, so that the support members 54 contact the extension rods 32, lift the extension rods 32 upward, and then drive the storage rack 3 to move upward, so that the storage rack 3 moves to the side and upper part of the cleaning tank 21.

[0048] Afterwards, the driving unit 42 controls the walking frame 41 to move along the crossbeam 11, adjusts the horizontal position of the lifting assembly 5 and the storage rack 3, so that the storage rack 3 moves to directly above one of the cleaning pools 21, and then the power unit 53 drives the lifting beam 52 to descend, so that the metal products in the storage rack 3 enter the cleaning pool 21 and are immersed in the cleaning liquid in the cleaning pool 21 for cleaning.

[0049] After cleaning is completed, the power unit 53 drives the storage rack 3 to rise through the lifting beam 52 and the support 54, so that the storage rack 3 moves to above the cleaning tank 21, and then adjusts the horizontal position of the lifting beam 52 and the storage rack 3 through the walking component 4, so that the storage rack 3 moves to just above another cleaning tank 21. Then, the lifting beam 52 is controlled to descend by the power unit 53, so that the metal products in the storage rack 3 are immersed in the cleaning liquid in the other cleaning tank 21 for cleaning.

[0050] In this way, the lifting assembly 5 and the walking assembly 4 cooperate with each other, and the support members 54 support the extension rods 32 on both sides of the frame 31, thereby driving the frame 31 to move horizontally and up and down, so that the frame 31 enters and exits each cleaning pool 21 in turn, and the metal products inside the frame 31 are immersed in the cleaning liquid, realizing automatic cleaning of the metal products, thereby reducing the burden on the operators, reducing labor costs, and improving cleaning efficiency.

[0051] The frame 1 of this embodiment specifically includes two cross beams 11 distributed side by side in the vertical direction, both ends of the cross beam 11 are fixedly connected to pillars 12, the bottom ends of the pillars 12 are fixedly connected to the base 13, and the cross beam 11, the pillars 12 and the base 13 are welded and fixedly connected; in order to facilitate the control of the walking component 4 and the lifting component 5, the slide rail 51 is fixedly connected to the controller 7 through the connecting frame 71, and the controller 7 can conveniently control the action of the drive unit 42 and the power unit 53 to control the movement of the walking frame 41 on the cross beam 11 and adjust the height position of the lifting beam 52.

[0052] In order to facilitate the timely discharge of the cleaning liquid in the cleaning pool 21 after cleaning, a drain pipe 23 is provided at the bottom of the side wall of the cleaning pool 21. The drain pipe 23 is connected to a drain valve 24. The controller 7 can control the opening and closing of the drain valve 24.

[0053] In order to ensure the compactness of the device structure, five cleaning pools 21 are provided in this embodiment and are connected in sequence. Specifically, the five cleaning pools 21 are composed of a cleaning trough with closed ends and four partitions distributed in sequence along the length direction of the beam 11. In this way, the five cleaning pools 21 are connected and arranged in sequence, ensuring the compactness of the device structure and reducing the occupied space.

[0054] In order to facilitate the placement of the storage rack 3 and determine the placement position of the storage rack 3, the support member 54 in the lifting assembly 5 is convenient for lifting the storage rack 3 upward, and storage platforms 25 are provided at both ends of the cleaning tank. The top surface of the storage platform 25 is provided with four positioning blocks 26 with a horizontal plane projection of L shape. The positioning area formed by the four positioning blocks 26 coincides with the four sides of the bottom of the rack body 31. In this way, it is convenient to determine the storage position of the storage rack 3 on the storage platform 25, and it is convenient for the lifting assembly 5 to accurately grab the storage rack 3 from one of the storage platforms 25 and place the metal products in the storage rack 3 in the cleaning tank 21 for cleaning. After cleaning, the storage rack 3 is accurately placed on another storage platform 25. In the placed state, the bottom of the storage rack 3 is in contact with the four positioning blocks 26.

[0055] A further improvement is that the support member 54 includes a bracket 541 with an open top, and the bracket 541 corresponds one-to-one with the extension rod 32; the bracket 541 and the extension rod 32 both extend in the horizontal direction. The bracket 541 and the extension rod 32 both extend in a horizontal direction parallel to the length of the beam 11, so that the driving unit 42 drives the traveling frame 41 to move on the beam 11. After the position of the bracket 541 is adjusted so that the bracket 541 moves directly below the extension rod 32, the lifting beam 52 is driven upward by the power unit 53, and the bracket 541 is moved upward to contact the extension rod 32, thereby driving the storage rack 3 to move up and down, and relying on the traveling assembly 4 to achieve smooth movement parallel to the length of the beam 11.

[0056] Furthermore, the width of the slot opening of the bracket 541 is greater than the outer diameter of the extension rod 32, and the width of the slot opening of the bracket 541 is greater than the width of the slot bottom of the bracket 541, with the slot opening of the bracket 541 gradually transitioning to the slot bottom of the bracket 541. This design increases the slot opening width of the bracket 541, making it easier for the extension rod 32 to enter the inner side of the bracket 541 after the bracket 541 moves upward, thereby achieving connection between the bracket 541 and the extension rod 32, thereby facilitating the vertical and horizontal movement of the bracket 541, respectively, and achieving the vertical and horizontal movement of the storage rack 3.

[0057] A further improvement is that at least two extension rods 32 are provided on both sides of the frame 31. The extension rods 32 on the same side of the frame 31 are arranged side by side parallel to the length of the crossbeam 11. This design increases the number of extension rods 32 on both sides of the frame 31 and the number of brackets 541 at both ends of the crossbeam 11, thereby increasing the number of contact points between the lifting assembly 5 and the storage rack 3. This ensures smooth lifting and horizontal movement of the storage rack 3 when the lifting assembly 5 and the travel assembly 4 are in operation.

[0058] Specifically, such as Figures 8-11 As shown, two extension rods 32 are provided on both sides of the rack body 31. The two extension rods 32 are distributed side by side along the length direction parallel to the beam 11, which is conducive to ensuring the smooth grasping and movement of the storage rack 3, and reduces the number of extension rods 32, thereby reducing the production cost of the storage rack 3.

[0059] Correspondingly, the support members 54 at the ends of the lifting beam 52 include two brackets 541 distributed along the length direction parallel to the crossbeam 11. The projection of the bracket 541 on the horizontal plane is separated from the projection of the cleaning pool 21 on the horizontal plane. A vertical plate 542 is fixed to the end of the bracket 541 away from the cleaning pool 21. A lower clamping plate 543 is fixed to the top of the vertical plate 542. An upper clamping plate 544 is arranged directly above the lower clamping plate 543. The upper clamping plate 544 and the lower clamping plate 543 are both arranged horizontally and abut against the top and bottom surfaces of the lifting beam 52 respectively. The upper clamping plate 544 and the lower clamping plate 543 are rectangular plates of the same size, and four pairs of threaded third bolts 545 and third nuts 546 are arranged at the four corners of the two, so that the end of the lifting beam 52 is clamped and fixed between the upper clamping plate 544 and the lower clamping plate 543, thereby realizing a fixed connection between the lifting beam 52 and the bracket 541. In order to ensure that the width of the slot opening of the bracket 541 is greater than the width of the slot bottom, the bracket 541 preferably adopts a V-shaped slot.

[0060] A further improvement is that a support 33 is provided on both sides of the outside of the rack 31, and the support 33 is located below the extension rod 32. A positioning groove 22 corresponding to the support 33 is provided on the cleaning pool 21, and the support 33 is used to be inserted into the positioning groove 22 to support and position the storage rack 3 through the positioning groove 22.

[0061] Specifically, the entrusted member 33 is a entrusted rod, and its axis is parallel to the axis of the extension rod 32 . The entrusted members 33 are arranged one-to-one directly below the extension rod 32 . The positioning groove 22 is also preferably a V-shaped groove, extending in a horizontal direction perpendicular to the beam 11 .

[0062] After adopting the above design, when it is necessary to clean the metal products inside the storage rack 3, the lifting beam 52 is controlled to rise by the lifting component 5, so that the bottom of the storage rack 3 is higher than the cleaning tank 21, and the horizontal position of the lifting beam 52 and the storage rack 3 is adjusted by the walking component 4, so that the entrusted part 33 on the storage rack 3 is located directly above the positioning groove 22, and then the lifting component 5 drives the lifting beam 52 and the storage rack 3 to descend, so that the entrusted part 33 enters the positioning groove 22, thereby fixing the position of the storage rack 3 during cleaning, and at the same time, the bracket 541 moves downward to disengage from the extension rod 32. After cleaning is completed, the lifting component 5 controls the lifting beam 52 to move upward again, so that the bracket 541 also contacts the extension rod 32, thereby driving the storage rack 3 to move upward.

[0063] A further improvement is that the traveling frame 41 is provided with outer rollers 411 and top rollers 412, each of which rotates about its own axis. The outer rollers 411 are provided on both sides of the beam 11, and their circumferential outer edges are attached to the side walls of the beam 11. The circumferential outer edges of the top rollers 412 are attached to the top surface of the beam 11. The driving unit 42 drives one of the outer rollers 411 or the top roller 412 to rotate about its own axis. The cross section of the beam 11 is rectangular.

[0064] After adopting the above structure, the outer rollers 411 and the top rollers 412 respectively contact the two side walls and the top wall of the beam 11 and rotate around their own axis, thereby ensuring the smooth movement of the walking frame 41 on the beam 11, reducing friction during movement, and reducing power consumption.

[0065] The slide rail 51 is fixedly connected to two traveling frames 41, and the two traveling frames 41 move on the two beams 11 in a one-to-one correspondence. Specifically, Figures 1-4 As shown, the drive unit 42 is connected to the top roller 412 on the upper walking frame 41 through transmission. The drive unit 42 includes a drive motor 421 and a drive reducer 422. The outer shell of the drive motor 421 is fixedly connected to the walking frame 41 through the outer shell of the drive reducer 422. The output end of the drive motor 421 is connected to the top roller 412 through the drive reducer 422. After the drive motor 421 is running, the top roller 412 rotates around its own axis, thereby driving the remaining top rollers 412 and the remaining outer rollers 411 to rotate around their own axis, thereby realizing the translation of the walking frame 41.

[0066] The specific structure of the walking frame 41 is as follows: Figure 6 and Figure 7 As shown, a rectangular plate-shaped flange 413 is provided at the bottom circumferential outer edge of the walking frame 41, and two top rollers 412 distributed along the length direction of the crossbeam 11 are provided on the walking frame 41, and the axis of the top roller 412 extends along the axial direction parallel to the extension rod 32 and the circumferential outer edge protrudes from the bottom surface of the walking frame 41; the outer roller 411 is arranged below the four corners of the flange 413, and the axis of the outer roller 411 extends along the plumb direction. Specifically, a rotating shaft 414 extending along the plumb direction is passed through the inner side of the outer roller 411, and a convex ring 417 is provided on the rotating shaft 414 that respectively fits the top and bottom surfaces of the outer roller 411, and a first screw 415 is connected to the top coaxially. The first screw 415 is threadedly connected to a first nut 416 that abuts the top surface of the flange 413 to fix the position of the first screw 415 and the rotating shaft 414, so as to facilitate the outer roller 411 to rotate around its own axis.

[0067] A further improvement is that the power unit 53 includes a power motor 531 fixed on the slide rail 51, a winding drum 532 connected to the output end of the power motor 531, and a winding belt 533 whose two ends are respectively connected to the winding drum 532 and the lifting beam 52; the slide rail 51 is a slide groove, and the end of the lifting beam 52 adjacent to the slide rail 51 is a sliding end, and the top and bottom of the sliding end are provided with inner rollers that roll around their own axis, and the inner rollers include an inner roller 55 whose circumferential outer edge is in contact with the inner bottom wall of the slide groove and an inner roller 55 in contact with the inner side wall of the slide groove.

[0068] Specifically, such as Figures 8-10As shown, the lifting beam 52 includes a beam body 521 extending in the horizontal direction, and the end of the beam body 521 adjacent to the frame 1 is plugged with a sleeve 522, and the sleeve 522 and the beam body 521 are fixedly connected by a second screw 524 and a second nut 525 connected by threads. A slider 523 is fixed to the end of the sleeve 522 away from the beam body 521, and the sliding end is arranged on the slider 523. The slider 523 is located on the inner side of the slide rail 51, and the top and bottom surfaces of the slider 523 are both provided with an inner bottom roller 56 and two inner rollers 55. The inner bottom roller 56 is in contact with the inner bottom wall of the slide rail 51, and the inner rollers 55 are in contact with the two inner side walls of the slide rail 51 to ensure that the lifting beam 52 moves smoothly in the vertical direction.

[0069] A connecting sleeve 526 extending parallel to the length of the crossbeam 11 is fixed directly above the beam 521. The connecting sleeve 526 rotates about its own axis above the beam 521. The power unit 53 also includes a power reducer 534 disposed between the slide rail 51 and the power motor 531. The input and output ends of the power reducer 534 are respectively connected to the input end of the power motor 531 and the winding drum 532. One end of the winding belt 533 is disposed on the winding drum 532, and the other end is connected to the connecting sleeve 526. After the power motor 531 is started, the power reducer 534 acts on the winding drum 532, driving the winding drum 532 to rotate about its own axis, winding or unwinding the winding belt 533, thereby achieving the lifting and lowering movement of the lifting beam 52.

[0070] Second embodiment

[0071] like Figure 12-14 As shown, the cleaning device of the second embodiment of the utility model is based on the first embodiment, with the difference that the slide rail 51 is also connected to a drying component 6, which includes a fan 61, and the fan 61 is used to dry the metal products on the storage rack 3 after immersion cleaning.

[0072] The air-drying component 6 can be used to dry the cleaning liquid on the surface of the metal product after cleaning to avoid mixing of different types of cleaning liquids. Specifically, the air-drying component 6 also includes an air duct 62. The axial direction of the air duct 62 is parallel to the length direction of the beam 11. The air duct 62 is fixedly connected to the slide rail 51 through a bracket 64. The fan 61 is arranged on the inner side of the air duct 62, and a filter 63 is also provided at both ends of the air duct 62.

[0073] After adopting the above structure, the fan 61 is started, the air flow range is limited by the air duct 62, and the filter 63 is used to prevent external dust particles from entering the air duct 62, so that the air duct 62 can blow air toward the storage rack 3 to dry the metal products on the storage rack 3.

[0074] A baffle 8 is also provided on the other side of the slide rail 51, which is vertically arranged and facing the air duct 62. The baffle 8 is used to prevent the droplets of cleaning liquid carried by the air from being blown into other cleaning pools 21 and on the ground, thereby avoiding pollution of the environment and mixing of different cleaning liquids in the cleaning pool 21, thereby ensuring the cleaning effect.

[0075] 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.
