The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention.
Example 1
As shown in fig. 2-11, the embodiment provides a mounting structure of a wheel of a sintering machine, which comprises a frame 1, a trolley wheel shaft 2 and a clamping plate 3, wherein the frame 1 is provided with a first mounting hole 11, and threads are arranged in the first mounting hole 11; the trolley wheel shaft 2 is provided with threads, and the trolley wheel shaft 2 is in threaded fit with the first mounting hole 11; one end of the trolley wheel shaft 2 is rotatably connected with a wheel 100, and the other end of the trolley wheel shaft 2 is provided with a clamping groove 21 extending along the radial direction; the clamping groove 21 is configured such that the clamping groove 21 is positioned outside the first mounting hole 11 after the trolley wheel shaft 2 is in threaded connection with the trolley frame 1; the clamping plate 3 and the clamping groove 21 can be clamped, the clamping plate 3 is provided with a fixing hole, the screw 4 penetrates through the fixing hole and then is connected with the second mounting hole 12 of the frame 1, the clamping plate 3 is used for preventing the trolley wheel shaft 2 from rotating around the axial direction, namely, the clamping plate 3 can prevent the trolley wheel shaft 2 and the frame 1 from rotating relatively.
According to the mounting structure of the sintering machine trolley wheel, the clamping groove 21 is formed in the radial direction of the trolley wheel shaft 2, after the trolley wheel shaft 2 is in threaded connection with the frame 1, the clamping plate 3 is clamped with the clamping groove 21, the clamping plate 3 is fixed on the frame 1 through the screw 4, and the clamping plate 3 can prevent the trolley wheel shaft 2 from rotating relative to the frame 1. The trolley wheel shaft 2 and the frame 1 are quickly assembled and disassembled by the screw connection, so that the assembly and disassembly efficiency is improved. In addition, the screw connection mode also avoids the problem that after the frame 1 and the trolley wheel shaft 2 are disassembled and assembled for a plurality of times, the gap between the first mounting hole 11 and the trolley wheel shaft 2 is enlarged, so that the trolley wheel shaft 2 and the frame 1 are not firmly fixed, and the accident that the trolley wheel shaft 2 and the trolley frame 1 are separated is caused.
With respect to the structures of the bottom of the card slot 21 and the top end portion of the card 3, in this embodiment, alternatively, the bottom of the card slot 21 may be a planar structure, and the contact end of the card 3 with the card slot 21 may be a planar structure. Of course, in other embodiments, the top end portions of the clamping plates 3 may be inclined structures, or arc structures, wherein the arc structures cannot rotate around the axle center of the trolley axle 2.
In order to prevent the trolley wheel shaft 2 from rotating relative to the frame 1 after being fixed with the clamping plate 3, when the trolley wheel shaft 2 is in threaded connection with the frame 1, the angle of the trolley wheel shaft 2 needs to be controlled according to the fixed position of the clamping plate 3, so that the bottom of the clamping groove 21 can be parallel to the abutting side of the clamping plate 3, and after the clamping plate 3 is clamped with the clamping groove 21, the fixing hole of the clamping plate 3 needs to be aligned with the second mounting hole 12 of the frame 1. However, in the installation process, too much rotation of the trolley wheel shaft 2 causes too much clamping grooves 21 to pass through the frame 1 and too large gaps between the clamping plates 3 and the frame 1 after being matched with the clamping plates 3, which is not beneficial to stability; the trolley wheel shaft 2 rotates too little, and the clamping groove 21 cannot pass through the first mounting hole 11 and cannot be clamped with the clamping plate 3. For this purpose, in the present embodiment, the bogie wheel axle 2 is provided with a plurality of catching grooves 21 in the circumferential direction. Preferably, six clamping grooves 21 are formed in the circumferential direction of the trolley wheel shaft 2. Specifically, when the width dimension of the clamping plate 3 is larger than the diameter dimension of the trolley wheel axle 2, the clamping groove 21 needs to penetrate the trolley wheel axle 2 in the length direction, and at this time, the radial tangential plane of the trolley wheel axle 2 at the clamping groove 21 is polygonal. Preferably, the radial section of the trolley axle 2 at the clamping groove 21 is hexagonal. In the process of screwing the trolley wheel shaft 2 and the frame 1, the clamping groove 21 is positioned outside the first mounting hole 11, the best matching position with the clamping plate 3 can be found within the range of 60 degrees, and the strength of the trolley wheel shaft 2 is considered in the setting.
Further, the frame 1 is provided with a plurality of second mounting holes 12 around the center of the first mounting hole 11. This setting makes the platform truck shaft 2 can be with cardboard 3 when joining in marriage, and the angle that can select is more, has improved installation effectiveness, and simultaneously, the platform truck shaft 2 is more suitable with the mounted position of frame 1.
Regarding the number of the second mounting holes 12, in this embodiment, preferably, the second mounting holes 12 are provided in five, and the angle between each two adjacent second mounting holes 12 may be any angle between 30 to 50 degrees, preferably thirty degrees. This setting makes can have thirty combinations between platform truck shaft 2 and the second mounting hole 12 in order to supply cardboard 3 to select, can both accomplish cardboard 3 and draw-in groove 21 joint under any combination, and cardboard 3 can be fixed in frame 1 through screw 4, has improved installation effectiveness, and can adjust the mounted position of cardboard 3 according to actual conditions to make the clearance between cardboard 3 and the automobile body 1 after the cardboard 3 is installed as little as possible.
When the clamping plate 3 is clamped with the clamping groove 21 and before being fixed on the frame 1 through the screw 4, the clamping plate 3 can slide off from the clamping groove 21. Therefore, in this embodiment, the clamping groove 21 includes a first stop groove 211, where the clamping plate 3 and the clamping groove 21 are matched, a first stop portion 31 is provided, and the first stop portion 31 is used for preventing the clamping plate 3 from being pulled out from the clamping groove 21 along the radial direction of the trolley wheel shaft 2, and can only be pulled out along the chord direction of the trolley wheel shaft 2, that is, can only be pulled out along the direction perpendicular to a certain diameter direction of the trolley wheel shaft 2, and the direction is not axial. Regarding the structure of the first stop portion 31, in this embodiment, specifically, the first stop portion 31 is a baffle, and the baffle is fixedly connected with the card 3 and is disposed at an included angle, preferably at a right angle, with the card 3. The angle between the first stopper groove 211 and the card groove 21 is the same as the angle between the shutter and the card 3. This arrangement prevents the card 3 from slipping out of the card slot 21 during installation.
When the trolley wheel shaft 2 and the frame 1 rotate, the screw 4 is subjected to shearing stress and is easily sheared, so that the trolley wheel shaft 2 is separated from the frame 1. For this reason, in the present embodiment, optionally, the frame 1 is provided with the second stop groove 13, the card 3 is provided with the second stop portion 32, the second stop portion 32 is configured such that the second stop portion 32 is engaged with the second stop groove 13 after the card 3 is engaged with the card groove 21, and the second stop portion 32 can abut against a side wall of the second stop groove 13. Regarding the structure of the second stop portion 32, in this embodiment, specifically, the second stop portion 32 is a pin, and the pin is fixedly connected with the card 3 and is disposed at an included angle, preferably at a right angle, with the card 3. The second stopper groove 13 extends along a line between the second mounting hole 12 and the first mounting hole 11. After the clamping plate 3 is clamped with the clamping groove 21, the second stopping part 32 is clamped with the second stopping groove 13. This arrangement reduces or eliminates the shearing stress to which the screw 4 is subjected, which is advantageous for improving the stability of the trolley axle 2.
Further, the frame 1 is uniformly provided with a plurality of second stop grooves 13 around the first mounting hole 11. On the one hand, the arrangement improves the installation speed of the trolley wheel axle 2; on the other hand, the mounting position of the clamping plate 3 can be adjusted according to actual conditions, a plurality of angles can be adapted to the rotation of the trolley wheel shaft 2, and the adaptability of the clamping plate 3 and the clamping groove 21 is improved, so that the gap between the clamping plate 3 and the trolley body 1 after the clamping plate 3 is mounted is as small as possible.
