Technical Field

[0001] The utility model relates to the technical field of steel sintering, in particular to a wheel assembly for a sintering machine trolley. Background Art

[0002] The sintering machine trolley is the main operating part of the sintering machine. The sintering machine is an industrial equipment mainly used for sintering operations. Its main function is to sinter raw materials such as concentrate powder and rich ore powder of different compositions and particle sizes into blocks, and to partially eliminate harmful impurities in the ore during the sintering process. The main function of the sintering machine trolley is to form a running rotary chain between the head and tail wheels of the sintering machine, receive the sintering mixed materials in the upper horizontal section, and return to the head wheel after preheating, ignition, sintering, cooling, and turning over, forming a transmission cycle;

[0003] Based on the importance of the sintering machine trolley in the sintering machine, its body is mainly composed of a trolley body, wheels, sealing devices, grates, baffles, and thermal insulation pads. Among them, the wheel assembly not only bears the weight of the entire trolley, but is also responsible for running smoothly on the track to ensure that the sintering process can be carried out continuously and stably. Therefore, the wheel assembly is also a very important component. The wheel assembly is generally composed of a wheel body and an axle rod. The wheel body is in direct contact with the track, bearing the weight of the trolley and the impact force generated during operation. The axle rod connects the wheel body and the trolley to play a supporting and transmission role. In actual operation, when limiting the axle rod, contact wear between the axle rod and the limiting device is inevitable. If the contact wear is too large, it will directly affect its service life and may even cause safety accidents. Utility Model Content

[0004] The utility model aims to provide a wheel assembly for a sintering machine trolley to solve the problem in the background art that excessive contact wear of the wheel assembly when limiting the position of the shaft rod will directly affect its service life.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a wheel assembly for a sintering machine trolley, comprising a wheel body, a first shaft body, and a second shaft body, a reserved groove is opened at the middle position inside the wheel body, the outer walls on both sides of the first shaft body are connected with edge sealing covers, the top and bottom ends of both sides of the first shaft body and the second shaft body are installed with blocks, a fourth installation groove is opened inside the block, a positioning groove is opened inside the first shaft body and the second shaft body, a second installation bolt is connected to the fourth installation groove and the positioning groove, an embedding groove is opened inside one side of the block, and a ball is embedded in the embedding groove.

[0006] Preferably, the blocks are symmetrically distributed about the central axis of the first shaft body or the second shaft body, and the positioning grooves are symmetrically distributed about the central axis of the first shaft body or the second shaft body.

[0007] Preferably, a threaded connection is formed between the second mounting bolt and the fourth mounting groove, and a threaded connection is formed between the second mounting bolt and the positioning groove.

[0008] Preferably, the inner diameter of the embedding groove is larger than the outer diameter of the ball, and one side of the ball contacts one side of the edge sealing cover.

[0009] Preferably, a connection block is installed at the top and bottom ends of one side of the edge sealing cover, a third installation groove is opened inside the connection block, a second installation groove is opened inside the wheel body, and a first installation bolt is connected inside the second installation groove.

[0010] Preferably, the second mounting grooves are symmetrically distributed about the center axis of the wheel body, a threaded connection is formed between the second mounting grooves and the first mounting bolts, and a threaded connection is formed between the third mounting grooves and the first mounting bolts.

[0011] Preferably, a threaded column is fixed on one side of the first shaft, an adsorption mounting ring is fixed on one side of the threaded column, a first mounting groove is opened inside one side of the second shaft, and a first adsorption block is installed on one side of the inner wall of the first mounting groove.

[0012] Preferably, a threaded connection is formed between the first mounting groove and the threaded column, and an adsorption fixation is formed between the adsorption mounting ring and the first adsorption block.

[0013] Compared with the prior art, the beneficial effects of the utility model are: the wheel assembly for the sintering machine trolley not only improves the contact limit protection capability, but also improves the limit installation convenience and shaft installation capability of the wheel assembly;

[0014] (1) The positioning groove is opened inside the first shaft body and the second shaft body, specifically inside the top end and the bottom end, and then the fourth installation groove is opened inside the stopper. When in use, the second installation bolt is connected to cooperate with the fourth installation groove and the positioning groove to complete the connection and installation between the first shaft body or the second shaft body and the stopper. When installed, the side of the ball is located at the side position of the edge cover. Since the ball is embedded in the embedded groove and can roll in contact, when the edge cover completes the side limit installation, the stopper plays a role in positioning and limiting, and can reduce a certain contact wear phenomenon under the operation of the ball, thereby better improving the overall contact protection capability during the operation and improving the service life;

[0015] (2) The first shaft body and the second shaft body are combined and installed inside the reserved groove. At this time, the edge cover is installed on one side of the first shaft body or the second shaft body, and the top and bottom ends of one side of the edge cover are both provided with a third installation groove, and the second installation groove is provided inside the wheel body. Therefore, during operation, the first installation bolt can be used in conjunction with the third installation groove and the second installation groove to complete the connection and installation between the edge cover and the wheel body. Therefore, after the wheel body and the edge cover are constructed as a whole, the side edges of the first shaft body and the second shaft body are sealed and limited, and at the same time, the operation of the wheel body is not restricted. Therefore, the overall convenience of limited installation is better improved during operation;

[0016] (3) The first shaft body is fixed on one side by a threaded column, the first installation groove is opened inside the second shaft body, and the adsorption installation ring is fixed on the side of the threaded column. Therefore, when the first shaft body and the second shaft body are combined, the first installation groove and the threaded column can be used to complete the connection and installation between the first shaft body and the second shaft body. At the same time, the first adsorption block and the adsorption installation ring are finally adsorbed and fixed to achieve the purpose of stable connection, thereby improving the overall shaft installation convenience during the working process.
