Description

Technical Field

[0001] This utility model relates to the field of roller press installation and maintenance technology, specifically to a maintenance support structure for a planetary reducer of a roller press. Background Art

[0002] Currently, the installation and disassembly of the two planetary reducers of the roller press are generally carried out using overhead cranes, truck cranes, or on-site gantry cranes with chain hoists for adjustment. After aligning the hollow shaft of the reducer with the roller shaft of the extrusion roller, axial force is applied to the reducer to install or disengage the hollow shaft of the reducer from the roller shaft of the extrusion roller. During the installation and disassembly of the reducer, the position of the overhead crane, truck crane, or chain hoist needs to be constantly adjusted to ensure that the hollow shaft of the reducer and the roller shaft of the extrusion roller remain aligned. The process is cumbersome and time-consuming. Moreover, the reducer has no support at the bottom, and if the chain breaks, it can cause equipment damage or even personal injury. Utility Model Content

[0003] The purpose of this utility model is to provide a maintenance support structure for a planetary reducer of a roller press, which enables the smooth installation and disassembly of the reducer, effectively reduces the installation and disassembly time, and lowers the equipment and personal safety risks during the maintenance and disassembly process.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a maintenance support structure for a planetary reducer of a roller press, comprising a lower support, a middle support, and an upper support arranged sequentially from bottom to top. The lower support is located directly below the planetary reducer of the roller press. Linear guide rails are fixed on both sides of the upper end of the lower support, and the direction of the guide rails is parallel to the roller shaft of the roller press. The lower end of the middle support is provided with a guide rail groove adapted to the guide rails. A lead screw parallel to the two guide rails is installed below the middle section of the middle support. The rotation of the lead screw drives the middle support to perform linear reciprocating motion along the guide rails.

[0005] The upper support includes two centrally symmetrical support plates and two horizontal base plates fixed below the support plates respectively. The base plates are fixedly connected to the middle support through a height adjustment mechanism. The upper part of the support plate is provided with a groove for supporting the planetary reducer. The center line of the groove is parallel to the center line of the planetary reducer and is on the same vertical plane.

[0006] Furthermore, the height adjustment mechanism includes several double-ended studs fixed to both sides of the base plate. The lower end of the double-ended studs is threaded to the middle bracket, and the upper end of the double-ended studs is threaded to two adjusting nuts for fastening and adjusting the base plate.

[0007] Furthermore, a support is fixed to the front end of the lower bracket, and a light hole is opened on the support for the lead screw to pass through. The lead screw is provided with back tightening nuts on both sides of the support to fix the lead screw to the support.

[0008] Furthermore, a nut seat is fixed below the middle bracket, and the lead screw is threadedly connected to the nut seat.

[0009] Furthermore, the contact surfaces of the guide rail and the guide rail groove are both made of stainless steel plates.

[0010] Furthermore, the lower bracket is fixed to the foundation by expansion bolts.

[0011] Furthermore, the support plate has several through holes near its edge for ropes to pass through.

[0012] Furthermore, the groove is adapted to the outer contour of the planetary reducer.

[0013] The beneficial effects of this utility model are as follows: The maintenance support structure of this utility model can adjust the height of the upper bracket through double-ended studs and adjusting nuts, and the axial horizontal movement of the reducer can be completed by adjusting the lead screw. The upper bracket plays a supporting role during the installation and disassembly of the reducer, making the operation simple and enabling quick installation and disassembly, saving time. When installing and disassembling the planetary reducer, there is no need for overhead cranes, hoists, or chain hoists, reducing labor and maintenance costs, while improving the safety of operators and equipment.

[0020] like Figure 1 , Figure 2 As shown, a maintenance support structure for a planetary reducer of a roller press includes a lower support 7, a middle support 5, and an upper support 1 arranged sequentially from bottom to top.

[0021] The lower support 7 is located directly below the planetary reducer 200 of the roller press. The lower support 7 includes four support legs that provide support. The lower ends of the support legs are fixed to the foundation by expansion bolts 12. Linear guide rails 8 are fixed on both sides of the upper end of the lower support 7. The direction of the guide rails 8 is parallel to the roller shaft of the roller press.

[0022] The lower end of the middle support 5 is provided with a guide rail groove 9 that matches the guide rail 8. A lead screw 6 parallel to the two guide rails 8 is installed below the middle section of the middle support 5. The rotation of the lead screw 6 drives the middle support 5 to perform linear reciprocating motion along the guide rail 8. Specifically, a nut seat is fixed below the middle support 5, and the lead screw 6 is threadedly connected to the nut seat. One end of the lead screw 6 is rotatably connected to the bearing seat on the lower support 7, and the other end is connected to the motor shaft of the drive motor. Of course, the lead screw 6 can also be manually rotated using a wrench or other tools. A support 10 is fixed to the front end of the lower support 7. The support 10 has a light hole for the lead screw 6 to pass through. On both sides of the support 10, there are back-tightening nuts 11 to fix the lead screw 6 to the support 10. When the upper support 1 is adjusted to a suitable position, the lead screw 6 stops rotating, and then the back-tightening nuts 11 fix the lead screw 6 to prevent axial movement.

[0023] The upper support 1 includes two centrally symmetrical support plates 2 and two horizontal base plates fixed below the support plates 2 respectively. The two base plates are spaced apart, and the two support plates 2 are longitudinally distributed along the roller shaft of the roller press. The two sides of the support plates 2 are reinforced by triangular wedges. The base plates are fixedly connected to the middle support 5 through a height adjustment mechanism. The upper part of the support plate 2 is provided with a groove for supporting the planetary reducer 200. The center line of the groove is parallel to the center line of the planetary reducer 200 and is on the same vertical plane. The upper support 1 is adjusted to a specified height so that the hollow shaft of the planetary reducer 200 is coaxial with the roller shaft of the roller press.

[0024] In specific implementation, the height adjustment mechanism employs several double-ended studs 3 fixed to the left and right sides of the base plate. The lower end of each double-ended stud 3 is threaded onto the middle support 5, and the upper end of each double-ended stud 3 is threaded onto two adjusting nuts 4. One adjusting nut 4 is connected to each of the upper and lower parts of the base plate, and the adjusting nuts 4 are used to tighten and adjust the base plate. The double-ended studs 3 and adjusting nuts 4 work together to precisely adjust the height of the upper support 1. Preferably, in this embodiment, two double-ended studs 3 are provided on each of the left and right sides of the base plate, and support platforms are fixed on the left and right sides of the middle support 5 at positions corresponding to the double-ended studs 3. The lower end of each double-ended stud 3 is threaded onto the support platform.

[0025] The grooves on the support plate 2 are adapted to the outer contour of the planetary reducer 200. The grooves can be V-shaped, arc-shaped, or inverted trapezoidal, etc. The grooves on the two support plates 2 support two parts of the planetary reducer 200 respectively. Each of the two support plates 2 has an independent base plate, so they do not interfere with each other when adjusting the height, which is conducive to quickly adjusting the upper bracket 1 to the specified height. Several through holes are opened near the edge of the support plate 2 to allow ropes to pass through, so as to tie the planetary reducer 200 and the upper bracket 1 together with ropes.

[0026] The lower support 7 does not interfere with the foundation of the torque support 201, slow drive, and universal joint protective cover of the planetary reducer 200 of the roller press. When installing or removing the planetary reducer 200, the flange of the torque support 201 does not interfere with the lower support guide rail and other components. Furthermore, the upper support 1, middle support 5, and lower support 7 can withstand the weight of the planetary reducer 200 and the flange of the torque support 201. The contact surfaces of the guide rail 8 on the lower support 7 and the guide rail groove 9 on the middle support 5 are both made of stainless steel plate. Preferably, the guide rail surface of the guide rail 8 is designed with 2mm thick stainless steel plate. Lubricating oil should be applied before use to reduce the coefficient of friction, making installation and removal of the reducer easier.

[0027] In practical use, after adjusting the position of the lower support 7, it is fixed to the foundation with expansion bolts 12. During maintenance, the upper support 1 is adjusted to the specified height using double-ended studs 3 and adjusting nuts 4. The two grooves of the upper support 1 support the outer contour of the planetary reducer 200. The planetary reducer 200 is tied to the upper support 1 with ropes. Rotating the screw drives the middle support 5, the upper support 1, and the planetary reducer 200 to move horizontally along the roller shaft of the roller press, thereby making the hollow shaft of the planetary reducer coaxial with the roller shaft of the roller press, achieving quick installation and removal of the planetary reducer. In use, two sets of maintenance support structures 100 can be set side by side to support the two planetary reducers of the roller press, respectively. Figure 2 As shown.

[0028] Compared with the traditional method of using cranes, hoists, or chain hoists to inspect and repair speed reducers, this device is simple to operate, allows for flexible adjustment of the speed reducer's position, saves time on installing and disassembling the speed reducer, reduces maintenance costs, and improves the safety of operators and equipment.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the scope of the concept and teaching of this utility model should be included within the scope of protection of this utility model.
