[0035] like Figures 1-3 As shown, this utility model provides a horizontal fine grinding mill multi-functional maintenance vehicle for carrying the grinding cylinder 5 of the fine grinding mill. It includes a frame 1, traveling wheels 4, and a support assembly. The bottom of the frame 1 has multiple mounting parts, and the traveling wheels 4 are connected to the mounting parts one by one. The top of the frame 1 has at least two first connecting parts and two second connecting parts arranged opposite to each other along the width direction of the frame 1, and the two first connecting parts and two second connecting parts are arranged opposite to each other along the length direction of the frame 1. The support assembly includes a support plate 2 and a locking plate 3. The support plate 2 is arranged one-to-one with the first connecting parts, and the locking plate 3 is arranged one-to-one with the second connecting parts. The locking plate 3 can be connected to the grinding cylinder 5.

[0036] Compared with existing technologies, the horizontal fine grinding mill multi-functional maintenance vehicle provided by this utility model has the following advantages:

[0037] The horizontal fine grinding mill multi-functional maintenance vehicle provided by this utility model has a frame 1 as the main load-bearing structure of the entire maintenance vehicle. Multiple mounting parts at the bottom of the frame 1 are used to accurately and stably install the traveling wheels 4, ensuring the stability and load-bearing capacity of the vehicle foundation.

[0038] The top of the frame 1 is uniquely equipped with two first connecting parts opposite each other along the width direction and two second connecting parts opposite each other along the length direction. This layout forms a rectangular support frame on the top of the frame 1. The support plate 2 in the support assembly is installed through the first connecting parts and is used to support most of the weight of the grinding cylinder 5. Their opposite arrangement ensures the balance of the support force. The locking plate 3 is installed through the second connecting parts, thereby establishing an active connection with the grinding cylinder 5, realizing the fixation of the grinding cylinder 5 on the frame 1, and preventing it from rolling or slipping off during movement.

[0039] During maintenance, the grinding cylinder 5 is hoisted onto the maintenance vehicle, allowing its body to rest on the support plates 2 on both sides. Then, the locking plate 3 is operated to connect with the grinding cylinder 5, thus firmly locking the grinding cylinder 5 onto the frame 1. Once the grinding cylinder 5 is connected to the maintenance vehicle, it can be moved to any location for corresponding operations according to specific needs, thereby solving the current problems of insufficient mobility of the lifting equipment and easy damage to the cylinder.

[0040] Furthermore, the maintenance vehicle provided in this application combines passive support with active locking, transforming the grinding cylinder 5 from a suspended state to a stable position on the mobile platform. This significantly improves the safety and controllability of the transfer process, avoiding wear and crush damage to the cylinder surface caused by the lifting ropes. Moreover, the maintenance vehicle can be flexibly moved to any flat site for maintenance, improving the flexibility and efficiency of the maintenance work. Simultaneously, the dual fixing method of support and locking effectively prevents accidents, ensuring the safety of personnel and equipment.

[0041] Optionally, such as Figures 1-3 As shown, both the support plate 2 and the locking plate 3 have arc-shaped support surfaces, and the support surfaces are adapted to the curvature of the outer wall of the grinding cylinder 5.

[0042] By designing all surfaces in contact with the grinding cylinder 5 as arc-shaped, and matching the radius of curvature of the outer wall of the grinding cylinder 5, the contact between the support plate 2 and the grinding cylinder 5 is transformed from point or line contact to a large-area, uniform surface contact. During operation, when the grinding cylinder 5 is placed on the maintenance vehicle, the arc-shaped support surface perfectly wraps around the lower outer wall of the grinding cylinder 5, greatly increasing the contact area under stress. The arc-shaped surface of the locking plate 3 provides better fit when connected to the grinding cylinder 5, reducing local stress concentration and significantly lowering the pressure per unit area. This effectively protects the cylinder wall of the grinding cylinder 5, preventing dents or scratches at the support points. Furthermore, the increased contact area and uniform force distribution make the grinding cylinder 5 more stable on the frame 1, reducing the tendency to sway. Simultaneously, the arc-shaped guiding effect facilitates the automatic sliding of the grinding cylinder 5 into the correct position during hoisting, simplifying the operation process.

[0043] Optionally, such as Figures 1-3 As shown, the support assembly also includes a locking member. A positioning hole 301 is formed on the locking plate 3. The positioning hole 301 can correspond to the inspection hole on the grinding cylinder 5. The locking member passes through the positioning hole 301 and the inspection hole to make the grinding cylinder 5 detachably connected to the locking plate 3.

[0044] By opening a positioning hole 301 on the locking plate 3 and using the inherent inspection hole on the grinding cylinder 5 body as a connection point, an additional locking component, such as a bolt or pin, passes through both the positioning hole 301 and the inspection hole, thereby achieving a mechanical hard connection between the grinding cylinder 5 and the maintenance vehicle.

[0045] The locking element and positioning hole 301 constitute the core of the detachable connection. During operation, the operator only needs to push the maintenance cart under the grinding cylinder 5, adjust its position so that the positioning hole 301 on the locking plate 3 aligns with the maintenance hole of the grinding cylinder 5, and then insert and tighten the locking element. This application, through the locking element and positioning hole 301 in conjunction with the maintenance hole, can make full use of the existing structure, achieve a standardized and universal connection, simplify operation, eliminate the need for customized tooling, and make installation and disassembly very convenient, improving maintenance efficiency without causing any additional damage to the grinding cylinder 5 body, fully meeting the basic requirements of equipment maintenance.

[0046] Optionally, such as Figures 1-3 As shown, the frame 1 in this application is rectangular and includes four longitudinal beam assemblies 101 arranged in a vertical direction and crossbeam assemblies connected between the longitudinal beam assemblies 101; the travel wheels 4 are installed at the bottom of the longitudinal beam assemblies 101 and are omnidirectional wheels.

[0047] The rectangular frame structure is more stable. Accordingly, the rectangular frame consists of four longitudinal beam assemblies 101 and crossbeam assemblies connecting them.

[0048] The longitudinal beam assembly 101 mainly bears the vertical pressure and bending moment, and is the "leg" of the frame 1. The bottom end of the frame 1 is directly mounted with the running wheels 4 to transfer the load to the ground. The crossbeam assembly connects the longitudinal beams to form a stable planar frame, which mainly bears the tensile, compressive and torsional forces, preventing the frame 1 from deforming when under load and moving, and ensuring the rigidity and stability of the overall structure.

[0049] Choosing omnidirectional wheels as the driving wheels 4 allows the vehicle to move forward, backward, and diagonally in any direction, rather than just in a straight line. During operation, especially in workshops or maintenance sites with limited space, operators can easily adjust the direction of movement of the maintenance vehicle, accurately transport the heavy grinding cylinder 5 to the target position, and even make small-angle rotation adjustments without having to perform complicated multiple steering operations, significantly improving work efficiency and ease of operation.

[0050] Preferably, the caster wheel in this application is provided with a locking mechanism for locking the caster wheel.

[0051] The locking mechanism is an additional device installed on the caster wheel. Its core function is to eliminate the "omnidirectional" degree of freedom of the caster wheel and temporarily turn it into a fixed wheel.

[0052] During operation, once the maintenance vehicle carrying the grinding cylinder 5 has moved to the designated work location (such as the maintenance station), the operator can lock all four, or two at the front, two at the rear, or at least two diagonal casters by operating the locking mechanism (usually by stepping on or rotating a handle 1013). This solves the technical problem and safety hazard of the maintenance vehicle accidentally moving due to uneven ground or slight external force under load, especially during maintenance work. It ensures the absolute stability of the maintenance vehicle when parked, providing a stable platform for the maintenance of the grinding cylinder 5 and avoiding work-related injuries or equipment collisions caused by vehicle slippage. At the same time, it also facilitates the operator's access to and from the frame 1, increasing the safety of the operation.

[0053] The locking mechanism is the same as the existing locking mechanism for swivel wheels, and can be the locking mechanism that comes with the swivel wheel itself, so it will not be described in detail here.

[0054] Optionally, such as Figures 1-3 As shown, the longitudinal beam assembly 101 in this application includes an outer beam 1011, an inner beam 1012, and an adjusting member; the outer beam 1011 is sleeved on the outside of the inner beam 1012, and the outer beam 1011 and the inner beam 1012 are movably connected; the adjusting member is used to adjust the position of the outer beam 1011 relative to the inner beam 1012; and the traveling wheel 4 is located at the bottom end of the inner beam 1012.

[0055] In this embodiment, the longitudinal beam assembly 101 is further designed as a sleeve type. The outer beam 1011 is a fixed part connected to the crossbeam of the frame 1, and the inner beam 1012 is a movable part that can extend and retract inside it. The wheels 4 are installed at the bottom of the inner beam 1012. The adjustment component is the core actuator for realizing the extension and retraction function. By operating the adjustment component, the inner beam 1012 is driven to retract upward or extend downward relative to the outer beam 1011, thereby driving the entire frame 1 to descend or rise. This can, to a certain extent, solve the technical problem of the maintenance vehicle adapting to grinding cylinders 5 of different diameters or external equipment of different heights for precise docking.

[0056] For example, a larger diameter grinding cylinder 5 requires a higher chassis 1 to ensure sufficient ground clearance. Furthermore, when reinstalling the grinding cylinder 5 back into the fine grinding mill, precise height adjustments may be necessary for a smooth connection. Therefore, the adjustable-height longitudinal beam assembly 101 greatly improves the versatility of the maintenance vehicle, allowing it to be used with various sizes of grinding cylinders 5, reducing equipment investment costs. The height-adjustable function also makes the loading and unloading process of the grinding cylinder 5 more precise and stable, reducing the risk of collisions and improving work quality. Additionally, when encountering uneven ground, the chassis 1 can be kept level by adjusting the height of the four corners, further enhancing its practicality.

[0057] Optionally, such as Figures 1-3As shown, the adjustment component in this application includes a handle 1013, a first bevel gear, a second bevel gear, a lead screw, and a mating component; the top of the outer beam 1011 has a mounting cavity, the first bevel gear and the second bevel gear mesh in the mounting cavity, one end of the handle 1013 extends into the mounting cavity and is connected to the first bevel gear, one end of the lead screw is connected to the second bevel gear, and the lead screw is connected to the outer beam 1011 and can rotate relative to the outer beam 1011; the mating component is disposed on the lead screw and is threadedly engaged with the lead screw, and the end of the inner beam 1012 away from the traveling wheel 4 is connected to the mating component.

[0058] Based on the above structure, this application provides a method for realizing the relative movement of the outer beam 1011 and the inner beam 1012. The handle 1013 is the human input end, and a pair of mutually perpendicular meshing first and second bevel gears form a reversing mechanism, converting the rotational motion of the handle 1013 from the vertical direction to the horizontal direction. The lead screw and its threaded mating parts constitute a helical transmission pair that converts the rotational motion into linear motion.

[0059] During operation, the operator turns handle 1013, causing the first bevel gear to rotate, which in turn drives the second bevel gear and the lead screw to rotate together. The rotation of the lead screw causes the threaded mating parts to move linearly along the lead screw axis. Since the mating parts are fixedly connected to the top of the inner beam 1012, and the lead screw rotates relative to the outer beam 1011 through bearings but does not move, the linear motion of the mating parts is directly converted into the extension and retraction motion of the inner beam 1012. By converting manual operation into two parts and utilizing the labor-saving characteristics of screw transmission, the technical problem of excessive operating force required for manual adjustment of heavy loads is solved. The bevel gear and lead screw transmission have a large transmission ratio, making operation very labor-saving. Even when carrying a grinding cylinder 5 weighing several tons, it can be easily adjusted. Furthermore, the lead screw transmission has excellent self-locking properties. When the handle 1013 is stopped, the mechanism can automatically lock in any position without the need for an additional locking device, ensuring safety and reliability. At the same time, the adjustment process is smooth, precise, and easy to fine-tune, achieving precise control of the height of the frame 1.

[0060] It should be noted that the adjustment components in this application are set one-to-one with the longitudinal beam assemblies 101, so that the height of a single longitudinal beam assembly 101 or any number of longitudinal beam assemblies 101 can be adjusted as needed, thereby improving the adaptability of the overall frame 1.

[0061] Optionally, such as Figures 1-3As shown, the crossbeam assembly in this application includes a first crossbeam member 102 and a second crossbeam member 103. The first crossbeam member 102 extends along the width direction of the frame 1, and the second crossbeam member 103 extends along the length direction of the frame 1. The first crossbeam member 102 includes an assembly section 1021 and a docking section 1022. One end of the assembly section 1021 is connected to the longitudinal beam assembly 101. Both longitudinal beam assemblies 101 arranged opposite each other along the width direction of the frame 1 are connected to the assembly section 1021. The two ends of the docking section 1022 are respectively inserted into the ends of the two assembly sections 1021 away from the longitudinal beam assembly 101, and are detachably connected to the assembly section 1021.

[0062] The beam assembly provided in this application includes a first beam member 102 extending in the width direction and a second beam member 103 extending in the length direction, which together form a robust rectangular frame. Preferably, the first beam member 102 provided in this application adopts a split design, consisting of an assembly section 1021 and a mating section 1022.

[0063] Assembly section 1021 is fixed to longitudinal beam assembly 101, providing a stable connection base. The docking section 1022 serves as a bridge connecting the two assembly sections 1021 and is connected to the assembly section 1021 by a detachable method (such as pin or bolt connection), thereby enabling the width of the frame 1 to be adjustable and facilitating disassembly and transportation.

[0064] If it is necessary to transport or store the maintenance vehicle, the docking section 1022 can be removed to separate the frame 1 in the width direction, thereby significantly reducing the overall volume.

[0065] The docking section 1022 can also be designed with multiple connection holes to adjust the width of the frame 1 to accommodate grinding cylinders 5 of different lengths, thereby effectively solving the technical problems of difficult transportation and large space occupation that are common in large tooling equipment.

[0066] Therefore, the split design greatly facilitates long-distance transportation and on-site handling of maintenance vehicles, reduces logistics costs, and makes it easy to store in warehouses or workshops, saving valuable space. At the same time, the docking section 1022 can also achieve adjustable width, further enhancing the equipment's versatility and adaptability, making its application range wider.

[0067] Optionally, such as Figures 1-3As shown, the horizontal fine grinding mill multi-functional maintenance vehicle provided in this application also includes a first support beam 104 and a second support beam 105. The first support beam 104 is arranged in a one-to-one correspondence with the support plate 2. There are two first crossbeam members 102 on one side of the support plate 2. The two first crossbeam members 102 are arranged at intervals along the height direction of the frame 1. The first support beam 104 extends in the vertical direction and is connected to the two first crossbeam members 102. The second support beam 105 is arranged in a one-to-one correspondence with the locking plate 3, and the second support beam 105 is arranged opposite to the second crossbeam member 103 in the vertical direction.

[0068] The first support beam 104 and the second support beam 105 are vertically arranged reinforcing structures. The first support beam 104 corresponds to the support plate 2 and connects the upper and lower first crossbeam members 102, forming a localized, robust support frame that effectively transfers and distributes the vertical load on the support plate 2 to the main structure of the frame 1. The second support beam 105 corresponds to the locking plate 3 and is vertically arranged on the second crossbeam member 103, providing a strong support base for the locking plate 3 to resist the horizontal and torsional moments generated when locking the grinding cylinder 5, preventing the mounting points of the support plate 2 and the locking plate 3 from deforming or being damaged due to bearing huge loads, and ensuring the smooth transmission of force.

[0069] During operation, when the heavy grinding cylinder 5 presses on the support plate 2, and the locking plate 3 bears the inertial force of the grinding cylinder 5 through the locking element, these support beams can significantly enhance the local stiffness and strength of the area, thereby solving the technical problem that the frame 1 may deform at key stress points due to insufficient strength or stiffness, affecting the safety and service life of use.

[0070] Optionally, the horizontal fine grinding mill multi-functional maintenance vehicle provided in this application also includes a hopper, which is detachably mounted on the frame 1.

[0071] The hopper is an independent container that is detachably connected to the frame 1. It is understood that since the frame 1 provided in this application is a rectangular frame, the middle area is hollow. The hopper provided in this application is designed according to the size of the hollow area and is embedded in the hollow area. In this way, the hopper can be used to carry some of the equipment needed during the operation or to collect the waste generated during the maintenance of the grinding cylinder 5, such as old bolts, gaskets, and leaked materials.

[0072] During operation, operators can attach or remove the hopper according to specific operational needs, allowing for easy access to tools or waste disposal while overhauling the grinding cylinder 5, thus maintaining a clean work site. After maintenance, the full hopper can be removed for proper disposal.

[0073] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
