Background Art

[0002] The base of the speed reducer for the stainless steel line across the roller table of the steel mill needs to be frequently stopped for replacement due to the high temperature environment and heavy load. This operation has the characteristics of long maintenance time and high installation precision requirements. Maintenance process: 1) Remove the original suspended speed reducer (referred to as: removal); 2) Hoist the speed reducer base (referred to as: hoisting); 3) Measure and install the speed reducer base (referred to as: installation); 4) Weld the speed reducer base (referred to as: welding). The existing commonly used speed reducer base installation method is to manually measure, locate and install the roller table speed reducer base. Due to the large number of roller table speed reducers that need to be replaced at the same time on the production line, the complex on-site environment, the small working space, the low efficiency of manual measurement and positioning, and the large error, rework is often caused, which affects the installation progress and makes it difficult to complete the replacement on time, affecting the production line production. At the same time, because the speed reducer is heavy, manual measurement and positioning requires the cooperation of the crane, and accurate positioning is difficult, resulting in a long installation time.

[0019] The technical solution of the present utility model will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] In order to more clearly illustrate the specific implementation methods of the utility model or the technical solutions in the prior art, the specific embodiments required to be used in the specific implementation methods or the description of the prior art will be briefly introduced below. Obviously, the specific embodiments described below are some implementation methods of the utility model. For ordinary technicians in this field, other specific embodiments can be obtained based on these specific embodiments without paying creative work.

[0021] The components of the embodiments of the present invention generally described and shown in the specific embodiments herein can be arranged and designed in countless different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the specific embodiments is not intended to limit the scope of the utility model claimed, but only represents the selected embodiments of the utility model.

[0022] See Figure 1-3 , is a schematic structural diagram of a tooling embodiment of the utility model for improving the installation efficiency of the roller reducer base, including a support 9, a sleeve 2, a level platform 1 and a positioning base 4. The positioning base 4 is connected to the sleeve 2 through the support 9. The sleeve 2 is horizontally arranged, and the inner hole at one end thereof is transitionally matched with the shaft head of the roller 6. The sleeve 2 is provided with a level platform 1. The position and size of the mounting holes on the positioning base 4 are consistent with the position and size of the mounting holes on the reducer base 7, and the reducer base 7 matches the installation size of the new reducer. The level platform 1 is centered relative to the positioning base 4 in both the longitudinal and transverse directions. A handle 3 is connected to the outer side of the support 9 for easy holding and operation. The reducer base 7 is fixedly connected to the H-shaped steel on the foundation 8 of the roller 6 by welding. The level on the level platform 1 is a universal level or a magnetic level.

[0023] The handle 3 includes a grip rod and a screw rod, one end of the two screw rods is vertically fixedly connected to the grip rod, and the other end of the screw rod is fixedly connected to the support 9 through a nut 5. A 2-3mm gasket is provided between the reduction box base 7 and the positioning base 4 for easy adjustment.

[0024] The utility model is a tool for improving the installation efficiency of the roller reducer base. The reducer base 7 can be quickly aligned and fixed by positioning the short axis of the roller 6 end and measuring with a level. The specific operation steps are as follows:

[0025] 1) Prepare the sleeve, remove the reduction box on the original roller, and leave only the roller on the support. Make a steel hollow sleeve 2, and precisely machine the inner hole of the front section of the sleeve 2 to form a transition fit with the short shaft at the end of the roller 6. The center line of the sleeve 2 is centered with the positioning base 4. The length of the sleeve 2 is determined according to the installation position of the new reduction box. Put the sleeve 2 into the short shaft at the end of the roller, and adjust the position of the positioning base 4 to the installation position of the reduction box.

[0026] 2) The level platform is in place, and the level platform 1 is welded on the top of the sleeve 2. The upper surface of the level platform 1 is precision machined. The level platform 1 is parallel to the center line of the sleeve 2, and the level platform 1 is parallel to the positioning base 4. The position of the level platform 1 is centered in the longitudinal and transverse directions of the positioning base 4. The level platform 1 is ensured to be in a horizontal state, and a level is used to perform horizontal alignment on the level platform.

[0027] 3) The positioning base is in place, and the support 9 is welded to the lower part of the sleeve 2. The handles 3 are connected to the two sides of the support 9. The positioning base 4 is welded to the lower part of the support 9. The positioning base 4 is provided with bolt holes drilled in accordance with the reducer base 7. The position of the positioning base 4 is determined according to the installation position of the new reducer; the distance between the center line of the sleeve 2 and the positioning base 4 is consistent with the distance between the center line of the short shaft at the end of the roller table 6 and the reducer base 7;

[0028] 4) Assemble and align, insert the shaft sleeve 2 of the tooling into the short shaft at the end of the roller table 6, adjust the position of the positioning base 4 to the installation position of the reducer, and use a spirit level to perform horizontal alignment on the spirit level platform 1. Keep the tooling still after leveling and aligning, and use the positioning base 4 to level and align the reducer base 7 and effectively fix it. When positioning, first put a 2-3mm gasket between the reducer base 7 and the positioning base 4 to adjust the height when installing the reducer, then align the bolt holes of the reducer base 7 and the positioning base 4, and fix them with bolts. After the adjustment and positioning are completed, fix the reducer base 7 by welding. After the reducer base 7 is installed and fixed, remove the tooling and install the new reducer on the reducer base 7.
