Description

Technical Field

[0001] This utility model relates to the technical field of tippler cleaning equipment, and in particular to a tippler track cleaning nozzle. Background Technology

[0002] In modern industrial bulk material transportation systems, tippers are core equipment for the efficient unloading of bulk materials such as coal and ore. The cleanliness of their tracks directly affects the stability and safety of the wagon operation. To avoid accidents such as jamming and derailment caused by material accumulation on the tracks, efficient and reliable track cleaning equipment is urgently needed. Currently, most mainstream tipper track cleaning devices on the market adopt a U-shaped frame structure, with nozzles installed on universal adjustment seats inside the frame for cleaning operations. However, this solution has two major technical bottlenecks:

[0003] Firstly, structural compatibility defects lead to both low adjustment efficiency and low cleaning effect. The fixed geometry of the U-shaped frame is difficult to match precisely with the complex curved contour of the tipper track, resulting in a large deviation between the initial installation angle of the nozzle and the cleaning surface of the track. Operators need to manually fine-tune the angle of each nozzle one by one, which is time-consuming. Moreover, manual operation is difficult to achieve precise positioning, resulting in overlapping or missed cleaning areas, and the cleaning effect is greatly reduced.

[0004] Secondly, the modular assembly poses significant risks to equipment reliability and maintenance efficiency. The equipment employs a distributed structural design, requiring on-site assembly and debugging of core components such as the universal adjustment seat and nozzles. This complex assembly process not only increases installation time but also increases the risk of structural instability due to accumulated component tolerances. In practical applications, after a period of operation, issues such as loose adjustment seats and nozzle misalignment arise, leading to frequent maintenance, reduced equipment availability, and difficulty in meeting the demands of continuous industrial production. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems in the related art.

[0006] Therefore, the purpose of this utility model is to propose a tippler track cleaning nozzle. The tippler track cleaning nozzle of this utility model adopts a Z-shaped frame with elastic support wheels, which can adapt to the contour of the I-beam track. It is easy to install and stable in operation. The adjustment mechanism can push the slider to adjust the angle of the outer spray pipe frame simultaneously and lock it precisely through the snap-fit ​​mechanism to achieve concentrated alignment of the spray position. The spray base and brush roller work together to clean the top of the track. Six sets of spray pipe frames adapted to the shape of the I-beam track can switch between dispersed or concentrated spray modes as needed to cover all surfaces of the track. The water distribution box supports separate delivery of water and cleaning agent. The spray pipe frame and other components adopt a quick-release design for easy maintenance. The overall structure is efficient and practical, easy to operate, and can effectively improve the track cleaning effect and equipment availability.

[0007] To achieve the above objectives, this utility model proposes a tippler track cleaning nozzle, comprising:

[0008] Z-shaped frame: set on the outside of the I-beam rail, with brush rollers evenly rotatably connected to the inner top wall, and the first support wheel and the second support wheel symmetrically rotatably connected to the inner side wall and the bottom corresponding to the upper and lower horizontal sections of the I-beam rail, respectively.

[0009] Water distribution box: It is fixedly connected to the top of the Z-shaped frame. The top is symmetrically provided with screw-in water inlet seats that are connected to external water pipes. The bottom is symmetrically provided with drain pipes that are connected to spray seats on the Z-shaped frame. Water distribution seats are symmetrically and evenly arranged in opposite directions on the surface.

[0010] Sprayer brackets: Symmetrically and evenly rotated and connected to the surface of the Z-shaped frame, corresponding to the position of the water distribution seat. Spray holes are evenly opened on the surface. One end of each of the multiple sets of sprayer brackets extends through the top of the Z-shaped frame and is fixedly connected to a connecting seat. The connecting seat is sleeved on the outside of the water distribution seat and communicates with the inside of the water distribution seat. Except for the middle set of connecting seats, the other sets of connecting seats are fixedly connected to the surface of the toothed ring and connected to the adjustment mechanism on the water distribution box.

[0011] In addition, the tippler track cleaning nozzle proposed in the above application may also have the following additional technical features:

[0012] Specifically, limit guide grooves are provided on the inner side wall and bottom of the U-shaped frame, corresponding to the positions of the first support wheel and the second support wheel. The mounting seats of the first support wheel and the second support wheel are horizontally slidably connected to the inner wall of the limit guide groove, and a first spring is fixedly connected between them and the inner wall of the limit guide groove.

[0013] Specifically, the spray base is symmetrically and integrally formed on the top wall of the U-shaped frame and located outside the brush roller. The spray nozzles of the spray base all face the brush roller. A water supply channel is opened at the top of the U-shaped frame. One end of the water supply channel is connected to the inside of the spray base, and the other end of the water supply channel is connected to the inside of the drain pipe.

[0014] Specifically, the number of nozzle brackets is set to six, and the nozzle brackets are adapted to the external dimensions of the I-beam rail.

[0015] Specifically, the adjustment mechanism includes a slider, a second spring, and a toothed plate. The slider is symmetrically and oppositely slidably connected to the limiting groove at the top of the water distribution box and connected to it by a snap-fit ​​mechanism. The second spring is sleeved on the outside of the snap-fit ​​mechanism and is fixedly connected to the surfaces of the two sets of sliders respectively. The toothed plate is symmetrically and oppositely slidably connected to the surface of the water distribution box and meshes with the toothed ring. One end of each toothed plate penetrates into the limiting groove and is fixedly connected to the surface of the slider.

[0016] Specifically, the locking mechanism includes an inner cylinder, an inner rod, an elastic locking element, and a locking hole. The inner cylinder and the inner rod are respectively threaded to the surfaces of two sets of sliders and are positioned correspondingly. One end of the inner rod is horizontally slidably connected to the inner wall of the inner cylinder. The elastic locking element and the locking hole are respectively provided at positions corresponding to the inner wall of the inner cylinder on the surface of the inner rod. The elastic locking element and the locking hole are locked and fixed.

[0017] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Improved structural adaptability and installation efficiency: The Z-shaped frame, combined with the elastic limiting design of the first and second support wheels, can adapt to the contours of I-beams of different specifications. The support wheel mounting base achieves lateral displacement adjustment through the limiting guide groove and the first spring, which can not only solve the structural interference problem during installation, but also maintain a tight fit with the rail surface through elasticity, thus shortening the equipment installation time and reducing the shaking amplitude during operation.

[0020] 2. Synchronous adjustment and precise locking of nozzle angle: The adjustment mechanism uses a linkage structure of slider, toothed plate and toothed ring. Pushing the slider can synchronously drive the outer nozzle frame to rotate, realizing the centralized alignment of the spray positions of the three sets of nozzle frames. A single adjustment takes only 3-5 seconds, which is significantly more efficient than the traditional manual adjustment one by one. The elastic clip and the locking hole design of the locking mechanism provide positioning accuracy and anti-displacement force, avoid angle deviation during operation, and significantly improve the cleaning coverage.

[0021] 3. Multi-dimensional cleaning function integration: The spray nozzle and brush roller work together to clean the top of the track: The spray nozzle faces the brush roller, and the water flow drives the bristles to perform a dual cleaning of the track surface by rinsing and friction; the six sets of spray pipe frames are adapted to the shape of the I-beam track and can achieve decentralized rinsing (mixing water and detergent) or concentrated rinsing (concentrated high-pressure water spray) through the adjustment mechanism, which significantly improves the cleaning efficiency for complex areas of the track.

[0022] 4. Modular design and ease of maintenance: The water distribution box can be connected to both water pipes and cleaning agent pipes simultaneously via a screw-in water inlet seat, and the built-in pipeline enables separate delivery of media; the spray nozzle frame and water distribution seat adopt a socket connection structure, which can be quickly replaced without tools during disassembly and assembly; the snap-fit ​​mechanism adopts a threaded connection structure of inner cylinder and inner rod, which allows the slider to be directly disassembled during maintenance, reducing the time required for component replacement and improving equipment availability.

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0031] The following description, in conjunction with the accompanying drawings, describes a tipper track cleaning nozzle according to an embodiment of the present invention.

[0032] like Figures 1-4 As shown in the figure, a tipper track cleaning nozzle according to an embodiment of the present invention includes:

[0033] Z-shaped frame 1: set on the outside of the I-beam rail, with brush rollers 11 evenly rotatably connected to the inner top wall, and first support wheel 12 and second support wheel 13 symmetrically rotatably connected to the inner side wall and bottom corresponding to the upper and lower horizontal sections of the I-beam rail, respectively.

[0034] Water distribution box 2: It is fixedly connected to the top of the Z-shaped frame 1. The top is symmetrically provided with screw-in water inlet seat 21 connected to the external water pipe, and the bottom is symmetrically provided with drain pipe 22 connected to the spray seat 14 on the Z-shaped frame 1. Water distribution seats 23 are symmetrically and evenly arranged in opposite directions on the surface.

[0035] The nozzle frame 3 is symmetrically and evenly rotated on the surface of the Z-shaped frame 1 and corresponds to the position of the water distribution seat 23. The surface is evenly provided with nozzle holes 31. One end of each of the multiple nozzle frames 3 passes through the top of the Z-shaped frame 1 and is fixedly connected to a connecting seat 32. The connecting seat 32 is sleeved on the outside of the water distribution seat 23 and communicates with the inside of the water distribution seat 23. Except for the middle set of connecting seats 32, the surfaces of the other sets of connecting seats 32 are fixedly connected with toothed rings 33 and connected to the adjustment mechanism 4 on the water distribution box 2.

[0036] It should be noted that the U-shaped frame 1 is connected to an external mobile device via the connecting ear 100.

[0037] It should be noted that, in order to prevent excessive water flow impact from causing the nozzle frame 3 to rotate, a damping ring is also installed at the connection between the nozzle frame 3 and the Z-shaped frame 1.

[0038] It should be noted that the number of screw-in water inlet seats 21 described in this embodiment is set to three sets, and the three sets of screw-in water inlet seats 21 can be connected to water pipes and different types of cleaning agent pipes respectively.

[0039] It should be noted that the water distribution seat 23 described in this embodiment is connected to the multi-component water box 2 and the spray seat 14 through built-in pipes (not shown in the figure), so that water and cleaning agent can be delivered and sprayed separately through the built-in pipes.

[0040] Specifically, the tipper track cleaning nozzle of this utility model adopts a Z-shaped frame 1 with elastic support wheels, which can adapt to the contour of the I-beam track. It is easy to install and runs stably. The adjustment mechanism 4 pushes the slider 41 to adjust the angle of the outer spray pipe frame 3 synchronously and locks it precisely through the snap-fit ​​mechanism 43 to achieve centralized alignment of the spray position. The spray base 14 and the brush roller 11 work together to clean the top of the track. The six sets of spray pipe frames 3 adapted to the shape of the I-beam track can switch between dispersed or concentrated spray modes as needed to cover all surfaces of the track. The water distribution box 2 supports the separate delivery of water and cleaning agent. The spray pipe frame 3 and other components adopt a quick-release design for easy maintenance. The overall structure is efficient and practical, and the operation is simple, which can effectively improve the track cleaning effect and equipment availability.

[0041] In use, the device is installed on an external mobile device via the connecting ear 100. Then, the pipes on the external mobile device are connected to the screw-in water inlet seat 21. Next, the device is fitted onto the outside of the I-beam rail. The external mobile device drives the device to move along the surface of the I-beam rail. During the movement, the device cleans the I-beam rail. Specifically, the top of the I-beam rail is cleaned via the spray seat 14 and the brush roller 11, and the other surfaces of the I-beam rail are cleaned via the spray nozzle frame 3. The angle of the spray nozzle frame 3 can be adjusted via the adjustment mechanism 4, which can achieve separate rinsing and concentrated rinsing. When rinsing separately, water pipes and detergent pipes can be connected. When rinsing in a concentrated manner, all water pipes can be connected.

[0042] In one embodiment of this utility model, such as Figure 2 As shown, limit guide grooves are provided on the inner side wall and bottom of the U-shaped frame 1, corresponding to the positions of the first support wheel 12 and the second support wheel 13. The mounting seats 131 of the first support wheel 12 and the second support wheel 13 are horizontally slidably connected to the inner wall of the limit guide groove, and a first spring 132 is fixedly connected between the first support wheel 12 and the inner wall of the limit guide groove.

[0043] It should be noted that the limiting guide groove described in this embodiment is not shown in the diagram.

[0044] It is understandable that both the first support wheel 12 and the second support wheel 13 are rotatably connected to the bottom of the mounting base 131.

[0045] Specifically, the combined design of the limiting guide groove, the mounting base 131, and the first spring 132 enables the first support wheel 12 and the second support wheel 13 to achieve lateral displacement adjustment, with specific advantages in two aspects:

[0046] First, improved installation adaptability: When the support wheel contacts the I-beam rail, the lateral displacement mechanism effectively resolves structural interference issues, allowing the component to be smoothly fitted onto the outside of the I-beam rail, reducing installation difficulty. Second, enhanced contact stability: The elastic force of the first spring 132 can push the support wheel to fit tightly against the surface of the I-beam rail. Through dynamic adaptive adjustment, it reduces shaking during operation and significantly improves the overall stability of the system. Through the synergistic effect of "displacement buffer + elastic compensation", it not only solves the structural conflict problem during installation, but also maintains a continuous and stable contact state through elasticity, resulting in good performance.

[0047] In one embodiment of this utility model, such as Figure 1 As shown, the spray base 14 is symmetrically and integrally formed on the top wall of the U-shaped frame 1 and located outside the brush roller 11. The spray nozzles of the spray base 14 are all facing the brush roller 11. A water supply channel is provided on the top of the U-shaped frame 1. One end of the water supply channel is connected to the inside of the spray base 14, and the other end of the water supply channel is connected to the inside of the drain pipe 22.

[0048] Specifically, the spray holder 14 adopts a symmetrical one-piece molding structure, fixed to the inner top wall of the Z-shaped frame 1, and located in the outer area of ​​the brush roller 11. Its spray nozzles are all set towards the brush roller 11 to ensure that water can accurately cover the connection between the roller and the I-beam rail, improving the cleaning effect. The top of the Z-shaped frame 1 is provided with a water supply channel. One end of the channel is connected to the inside of the spray holder 14, and the other end is connected to the inside of the drain pipe 22, thus forming a complete water supply path. This structural design ensures the installation accuracy of the spray holder 14 through the one-piece molding process. The symmetrical layout allows the spray range to cover the area where the outermost brush roller 11 contacts the I-beam rail. The connection design between the water supply channel and the spray holder 14 and the drain pipe 22 realizes the efficient transmission and recycling of the medium, resulting in good performance.

[0049] In one embodiment of this utility model, such as Figure 1 As shown, the number of nozzle brackets 3 is set to six, and the nozzle brackets 3 are adapted to the external dimensions of the I-beam rail.

[0050] It should be noted that, in this embodiment, three of the six sets of nozzle brackets 3 are set on one side.

[0051] Specifically, the quantity, layout, and shape of the nozzle frame 3 will be further explained.

[0052] In one embodiment of this utility model, such as Figure 3 As shown, the adjustment mechanism 4 includes a slider 41, a second spring 44, and a toothed plate 45. The slider 41 is symmetrically and oppositely slidably connected to the limiting groove 42 at the top of the water distribution box 2 and connected to it through the snap-fit ​​mechanism 43. The second spring 44 is sleeved on the outside of the snap-fit ​​mechanism 43 and is fixedly connected to the surfaces of the two sets of sliders 41 respectively. The toothed plate 45 is symmetrically and oppositely slidably connected to the surface of the water distribution box 2 and meshes with the toothed ring 33. One end of each toothed plate 45 penetrates into the limiting groove 42 and is fixedly connected to the surface of the slider 41.

[0053] Specifically, the structure and connection relationship of the adjustment mechanism 4 are further explained. The adjustment mechanism 4 can precisely control the synchronous adjustment of the angles of the two outer sets of nozzle frames 3, so that they rotate inward and are precisely aligned with the spray position of the middle set of nozzle frames 3. By converging the spray range of the three sets of nozzles, a concentrated rinsing area is formed, which can improve the cleaning effect by more than 30% compared with dispersed spraying. It is especially suitable for the efficient removal of stains on complex surfaces. The cleaning efficiency is high. When in use, push the two sets of sliders 41 inward. The movement of the two sets of sliders 41 synchronously drives the toothed plate 45 to move and compresses the second spring 44. The movement of the toothed plate 45 synchronously drives the toothed ring 33 to rotate. The rotation of the toothed ring 33 synchronously drives the two outer sets of nozzle frames 3 to rotate inward, so that their spray positions correspond to the spray positions of the middle set of nozzle frames 3. After releasing, the positions of the two sets of sliders 41 are fixed under the action of the locking mechanism 43.

[0054] In one embodiment of this utility model, such as Figure 4 As shown, the snap-fit ​​mechanism 43 includes an inner cylinder 431, an inner rod 432, an elastic snap-fit ​​element 433, and a snap-fit ​​hole 434. The inner cylinder 431 and the inner rod 432 are respectively threaded to the surfaces of two sets of sliders 41 and are positioned correspondingly. One end of the inner rod 432 is horizontally slidably connected to the inner wall of the inner cylinder 431. The surface of the inner rod 432 and the inner wall of the inner cylinder 431 are respectively provided with elastic snap-fit ​​elements 433 and snap-fit ​​holes 434 at corresponding positions. The elastic snap-fit ​​elements 433 and snap-fit ​​holes 434 are snap-fitted and fixed.

[0055] It should be noted that the engaging force between the elastic clip 433 and the clip hole 434 described in this embodiment is greater than the elastic force of the second spring 44.

[0056] Specifically, the structure and connection relationship of the locking mechanism 43 will be further explained. The locking mechanism 43 achieves position control of the two sets of sliders 41 through a dual design of precision positioning and rigid locking. It is simple to operate and has good performance.

[0057] When the slider 41 is pushed inward, the inner rod 432 drives the elastic locking piece 433 to slide inside the inner cylinder 431. The inclined wedge surface at the front end of the locking piece and the edge of the locking hole 434 undergo elastic deformation, passing over the initial locking hole 434 in sequence. When the slider 41 reaches the target position, the elastic locking piece 433 is precisely embedded into the corresponding locking hole 434 under the action of the return spring. The rear boss of the locking piece forms a surface contact lock with the end face of the inner cylinder 431, achieving rigid fixation with a "click" sound feedback.

[0058] In summary, this utility model provides a tippler track cleaning nozzle. The nozzle features a U-shaped frame 1 with elastic support wheels, adapting to the contour of the I-beam track. It is easy to install and operates stably. The adjustment mechanism 4 pushes the slider 41 to simultaneously adjust the angle of the outer spray nozzle frame 3, which is precisely locked by the locking mechanism 43, achieving centralized alignment of the spray positions. The spray base 14 and brush roller 11 work together to clean the top of the track. Six sets of spray nozzle frames 3, adapted to the shape of the I-beam track, can switch between dispersed and concentrated spray modes as needed, covering all surfaces of the track. The water distribution box 2 supports separate delivery of water and cleaning agent. The spray nozzle frames 3 and other components feature a quick-release design for easy maintenance. The overall structure is efficient and practical, easy to operate, and effectively improves track cleaning results and equipment usability.
