[0002] Typically, when disassembling and assembling the crushing roller, tools such as scaffolding, hand hoists, or gantry cranes are required for lifting and installation. This is because the installation locations of such equipment are often relatively narrow, making scaffolding and gantry cranes inconvenient to install and unsafe to use. The crushing roller weighs approximately one ton, and the balance point and center of gravity are unstable when hoisted with a hoist and slings, making the lifting risk very high and the work efficiency very low. The crushing roller is a precision component. After installation, the gap between the crushing rollers must be between 0.45-0.55 mm, and the parallelism of the crushing rollers must not exceed 0.00005. However, a crusher has a pair of crushing rollers, and a pair of crushing rollers is relatively expensive. The gap between the end face of the crushing roller and the bottom plate of the gear bearing seat is guaranteed to be 1 mm ± 0.2 mm. Once bumped or damaged, it cannot be used and needs to be returned to the factory for repair, which adds additional costs. Utility Model Content

Specific implementation plan

[0022] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. In this document, the terms "comprise", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a..." does not exclude the presence of other identical elements in the process, method, article or device that includes the element.

[0024] The inventors of this solution have found that in the prior art, disassembling and assembling the crushing roller is inconvenient and unsafe, because the crushing roller is expensive to manufacture. If the crushing roller is damaged during disassembly and assembly, a large repair cost will be added. This embodiment provides the following solution:

[0025] like Figures 1 to 4 As shown, this embodiment provides a maintenance device for a roller crusher, including a bracket 1 that can be raised and lowered, the bracket 1 is provided with a crushing roller placement platform 2, and a plurality of rotatable rollers 3 are provided at the bottom of the crushing roller placement platform 2. The number of rollers 3 can be adaptively set and adjusted according to the specific working conditions and the specific size of the crushing roller to meet the maintenance of the crusher. Of course, a part of the margin can also be left to meet the maintenance and disassembly of crushers and crushing rollers of different sizes.

[0026] It should be noted that when the crusher and crushing roller need to be disassembled and repaired, the bracket 1 needs to be moved to the outlet end of the crushing roller of the roller crusher first, and then the center height and levelness of the bracket 1 are adjusted according to the height adaptability of the crushing roller so that the crushing roller placement platform 2 is roughly flush with the bottom of the crushing roller, so as to facilitate the operation of disassembling and assembling the crushing roller later. After the bracket 1 is positioned, use tools such as a hand winch or a gantry crane to pull the crushing roller out of the crusher to the input port of the crushing roller placement platform 2, that is, the open end of the crushing roller placement platform 2 where the tension rod lifting ring 7 is not set. Because the bottom of the bracket 1 is provided with a roller 3 and the stop roller mounting bracket 21 is provided with a stop roller 6, the resistance in the process of dragging the crushing roller to the crushing roller placement platform 2 will be greatly reduced. The rotation of the roller 3 allows the crushing roller to be smoothly moved to the crushing roller placement platform 2, thereby effectively improving the safety, stability and reliability of crusher maintenance, thereby ensuring the quality of equipment maintenance.

[0027] Specifically, the rollers 3 can be arranged in a horizontal linear and uniform manner to improve the stability of the crushing roller moving on the rollers 3. Of course, a non-uniform arrangement can also be adopted, but the distance between two adjacent rollers 3 should not be too large to prevent the crushing roller from sliding due to unstable center of gravity when moving on the crushing roller placement table 2.

[0028] like Figure 1 As shown, the crushing roller placement table 2 is fixed and supported by a bracket 1, which includes two or more parallel horizontally arranged bottom brackets 11 that are rod-shaped as a whole, and two or more first brackets 12 and second brackets 13 that are perpendicular to the bottom brackets 11. Among them, the two or more first brackets 12 and the second brackets 13 are connected by one or more connecting rods 14 arranged therebetween. The connecting rods 14 play a role of linking support and stabilization between the first brackets 12 and the second brackets 13 to prevent the first brackets and the second brackets from tilting due to excessive pressure. The bottom ends of the first bracket 12 (the bottoms of the two support rods) are respectively fixedly connected to the bottom bracket 11, and the bottom ends of the second bracket 13 (the bottoms of the two support rods) are respectively connected to the bottom bracket 11. Here, the first bracket 12 and the second bracket 13 are each composed of two groups of support rods as an example, so the outermost support rods of the first bracket 12 and the second bracket 13 are respectively fixed to the two bottom brackets 11 correspondingly arranged on the outer side of the bottom of the bracket 1. At the same time, both ends of the top of the first bracket 12 (the tops of the two support rods) are connected to the side of the bottom of the crushing roller placement platform 2 where the stop roller 6 is located, and both ends of the top of the second bracket 13 (the tops of the two support rods) are connected to the other side of the bottom of the crushing roller placement platform 2 where the stop roller 6 is located. Of course, in order to increase the stability of the entire bracket, more sets of support rods can be added to the first bracket 12 and the second bracket 13, and the corresponding bottom bracket 11 can also be increased or appropriately adjusted accordingly. Here, only two sets are used as an example.

[0029] Furthermore, two lead screws 4 can be installed on the bottom bracket 11, such as Figure 1 and Figure 4 As shown, a lead screw 4 is provided at each end of the two support rods of the bottom bracket 11. By adjusting the thread of the lead screw 4, the lifting and horizontal adjustment functions of the entire device can be realized. In particular, when the entire device is positioned to the outlet of the crushing roller of the crusher, the height and level of the entire device can be fine-tuned by adjusting the lead screw 4 on the bottom bracket 11, so as to achieve the safe disassembly and maintenance of the crusher and the crushing roller to the greatest extent.

[0030] Furthermore, a plurality of universal wheels 5 may be installed at the bottom of the bottom bracket 11, for example Figure 1-5As shown in the figure, four universal wheels 5 can be installed. Of course, there are other options, such as three or six, etc., as long as the stability of the mobile device can be met. When the device is moved, the crushing roller placement table 2 may have already placed the disassembled crushing roller, so the number and position of the universal wheels 5 must meet the stability requirements. Through the setting of the universal wheels, the entire device can be freely moved to a suitable position during the disassembly and maintenance of the crushing roller. Of course, the screw 4 set on the bottom bracket 11 can also be used for stability control and support of the device in a stationary state.

[0031] For further information, please refer to Figure 1 As shown, the first bracket 12 includes a first lateral support rod 121 and a first bottom support rod 122, each formed by two groups of support rods. The second bracket 13 includes a second lateral support rod 131 and a second bottom support rod 132, each formed by two groups of support rods. The first bottom support rod 122 has two ends connected to the bottom bracket 11. One end of the first lateral support rod 121 is connected to the bottom of the crushing roller placement platform 2, and the other end of the first lateral support rod 121 is connected to the bottom bracket 11 and the first bottom support rod 122, respectively. The second bottom support rod 132 has two ends connected to the bottom bracket 11. One end of the second lateral support rod 131 is connected to the bottom of the crushing roller placement platform 2, and the other end of the second lateral support rod 131 is connected to the bottom bracket 11 and the second bottom support rod 132, respectively. Of course, the number of first lateral support rods 121 and second lateral support rods 131 can be increased or adjusted accordingly according to actual needs.

[0032] For further information, please refer to Figure 1 As shown, the first bracket 12 further includes a first transverse support rod 123 and a first central support rod 124, with the first transverse support rod 123 connected to the first central support rod 124. The second bracket 13 further includes a second transverse support rod 133 and a second central support rod 134, with the second transverse support rod 133 connected to the second central support rod 134. The first transverse support rod 123 has its ends connected to the first lateral support rod 121, while the second transverse support rod 133 has its ends connected to the second lateral support rod 131. The first central support rod 124 has its ends connected to the first bottom support rod 122 and the bottom of the crushing roller platform 2, while the second central support rod 134 has its ends connected to the second bottom support rod 132 and the bottom of the crushing roller platform 2. Of course, the number of the first transverse support rod 123, the first central support rod 124, the second transverse support rod 133, and the second central support rod 134 can be increased or decreased as needed.

[0033] The first transverse support rod 123 and the first middle support rod 124 improve the strength and stability of the first bracket 12 , and the second transverse support rod 133 and the second middle support rod 134 improve the strength and stability of the second bracket 13 .

[0034] For further information, please refer to Figure 1 As shown, a retaining roller mounting frame 21 is provided on each side of the crushing roller placement platform 2. A plurality of rotatable retaining rollers 6 are mounted on the retaining roller mounting frames 21. The retaining rollers 6 are arranged linearly and evenly. Of course, a non-uniform arrangement is also possible. However, the spacing between two adjacent retaining rollers 6 should not be too large to prevent the crushing roller from slipping out of the gap between the retaining rollers 6 when moving on the crushing roller placement platform 2. It should be noted that when the crushing roller moves to the crushing roller placement platform 2, the retaining rollers 6 can guide the crushing roller to move accurately to the crushing roller placement platform 2, thereby preventing the crushing roller from accidentally falling and reducing the resistance of the crushing roller to movement on the crushing roller placement platform 2.

[0035] Furthermore, at the rear end of the crushing roller placement platform 2, that is, at the other end away from the input port of the crushing roller placement platform 2, a tension rod lifting ring 7 for fixing a hand chain hoist is provided. It should be noted that there is a central threaded hole at the shaft end of the crushing roller, on which a lifting ring (not shown) is installed. When the crusher and crushing roller are actually disassembled and repaired, the hand chain hoist is first used to hang the hook on the lifting ring and the tension rod lifting ring 7 respectively, and then the manual hoist is operated to drag the crushing roller out of the crusher and continuously move it to the crushing roller placement platform 2. This saves physical effort in manual operation and improves the safety and stability of the operation.

[0036] In the specific implementation, the entire device is moved to the outlet of the crushing roller of the roller crusher, and then the center height and levelness of the bracket 1 are adjusted to make the crushing roller placement platform 2 and the bottom of the crushing roller roughly flush, and then the crushing roller is pulled out to the crushing roller placement platform 2 for maintenance by a hand winch. After maintenance, the crushing roller is moved horizontally into the position of the crusher mounting shaft seat for installation. Due to the setting of the support roller 3 and the stop roller 6, the installation after maintenance is ensured to be labor-saving and safe.

[0037] In summary, an embodiment of the present invention provides a maintenance device for a roller crusher, which is provided with a liftable bracket, a crushing roller placement platform is provided on the bracket, and the crushing roller placement platform is provided with multiple rotatable rollers, which can adjust the height according to the position of the crushing roller, and move the crushing roller horizontally to the platform of the device, thereby reducing the operational safety risk, improving operational safety and stability and reliability, and thus ensuring the quality of equipment maintenance.
