Abstract
Description
Technical Field
[0001] The utility model belongs to an auxiliary device for a grate reducer, and specifically relates to a supporting device for a connecting rod of a grate reducer. Background Art
[0002] The original grate reducer has no supporting device, and only a single push rod performs reciprocating pushing and pulling movements. The push rod is in a suspended state, and the up-and-down swing of the push rod is relatively large, which causes relatively large wear on the pin rod at the connecting part of the connecting rod and the push rod, and often breaks, requiring periodic replacement of spare parts. After installing the supporting device, by using the rolling of the bearing, it assists the grate reducer to perform reciprocating pushing and pulling operations, increases the stability of the connecting rod, reduces the wear of the connecting rod, and makes its movement more stable.
[0003] A bearing is an important component in contemporary mechanical equipment. Its main function is to support the rotating body of the machine, reduce the friction coefficient during its movement, and ensure its rotational accuracy. According to the different friction properties of the moving elements, bearings can be divided into two major categories: rolling bearings and sliding bearings. Among them, deep groove ball bearings in rolling bearings have been widely used. Deep groove ball bearings are the most widely used type of bearings in the mechanical industry and can usually bear radial loads and also a certain amount of axial loads. After the deep groove ball bearing is installed on the shaft, within the axial clearance range of the bearing, it can limit the axial displacement of the shaft or the housing in two directions, so it can be axially positioned in both directions.
[0004] A shaft is a cylindrical object that passes through the middle of a bearing, or the middle of a wheel, or the middle of a gear, but there are also a small number of square-shaped ones. A shaft is a mechanical part that supports rotating parts and rotates with them to transmit motion, torque, or bending moment. Generally, it is a metal round rod, and each section can have a different diameter. The rotating parts in the machine are installed on the shaft.
[0005] Therefore, there is an urgent need for a technology in the prior art to solve the above problems. Content of the Utility Model
[0006] The technical problem to be solved by the utility model is: to provide a device for the problems existing in the background art.
[0007] A supporting device for a connecting rod of a grate reducer, characterized in that: it includes a shaft, a bearing, a height adjusting device, and a fixed bracket;
[0008] The fixed bracket includes an upper bracket and a lower bracket, and the upper bracket and the lower bracket are connected by a height adjusting device;
[0009] A shaft is fixedly arranged on the upper bracket, and a bearing is arranged on the shaft;
[0010] The height adjustment device is a long strip plate with a through groove in the middle. The height adjustment devices are paired up and cooperated. Through holes for installing bolts are provided at both ends of the height adjustment device. Both ends of the height adjustment device are bolted to the upper bracket and the lower bracket respectively.
[0011] The shaft is a shaft with a diameter of 40 mm, and the bearing is a deep groove ball bearing.
[0012] The height adjustment device is a steel plate with a length, width and thickness of 100 mm * 30 mm * 5 mm respectively.
[0013] The height adjustment device is connected to the upper bracket and the lower bracket respectively through M8 * 20 bolts.
[0014] The fixed bracket is a support bracket made of 12# channel steel.
[0015] Through the above design, a support device applicable to the connecting rods of different grate reducers is provided, which reduces the wear of the pin and the push rod, extends the service life of the spare parts, and increases the supporting force of the connecting rod and the stability of the reciprocating motion. Brief Description of the Drawings
[0016] The following further describes the present utility model in conjunction with the drawings and specific embodiments:
[0017] Figure 1 is the side view of the present utility model;
[0018] Figure 2 is the front view of the present utility model;
[0019] In the figure: 1 - shaft, 2 - bearing, 3 - height adjustment device, 4 - fixed bracket, 41 - upper bracket, 42 - lower bracket, 9 - connecting rod. Specific Embodiments
[0020] The present application is further described in conjunction with the drawings:
[0021] A support device for the connecting rod of a grate reducer, characterized in that it includes a shaft 1, a bearing 2, a height adjustment device 3 and a fixed bracket 4;
[0022] The fixed bracket 4 includes an upper bracket 41 and a lower bracket 42, and the upper bracket 41 and the lower bracket 42 are connected through the height adjustment device 3;
[0023] The shaft 1 is fixedly arranged on the upper bracket 41, and a bearing 2 is arranged on the shaft 1;
[0024] The height adjustment device 3 is a long strip plate with a through groove in the middle. The height adjustment devices 3 are paired up in groups of two. Through holes for installing bolts are provided at both ends of the height adjustment device 3. Both ends of the height adjustment device 3 are bolted to the upper bracket 41 and the lower bracket 42 respectively.
[0025] The shaft 1 is a shaft with a diameter of 40 mm, and the bearing 2 is a deep groove ball bearing.
[0026] The height adjustment device 3 is a steel plate with a length, width and thickness of 100 mm * 30 mm * 5 mm respectively.
[0027] The height adjustment device 3 is connected to the upper bracket 41 and the lower bracket 42 respectively by M8 * 20 bolts.
[0028] The fixed bracket 4 is a support bracket made of 12# channel steel.
[0029] When installing the two ends of the height adjustment device 3 to the upper bracket 41 and the lower bracket 42, the bolt passes through the through groove on the first height adjustment device 3, passes through the through hole of the upper bracket 41 or the lower bracket 42, and then passes through the through groove of the second height adjustment device 3, and the bolt is tightened to complete the installation.
[0030] When the height needs to be adjusted, loosen the bolt to release the two ends of the height adjustment device 3 from the upper bracket 41 and the lower bracket 42, adjust the position of the bolt in the through groove, and tighten the bolt after adjustment to complete the adjustment.
[0031] In actual use, first adjust the height of the fixed bracket 4 according to the position of the connecting rod of the grate reducer. When adjusting the height of the fixed bracket 4, make the height of the bearing 2 match the connecting rod 9 of the grate reducer, so that the connecting rod 9 can contact the bearing 2 and assist the movement of the connecting rod 9.
