[0030] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices consistent with some aspects of the present disclosure as detailed in the appended claims.

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Embodiment 1:

[0033] like Figures 1 to 7 As shown, this embodiment provides a sintering machine grate bar pin structure, including a trolley 1, a baffle 5, a grate bar 6, a connecting hole 7, a fixing component 2, a quick-release component 3 and a gasket 4.

[0034] Among them, the trolley 1 is used to carry and transport mixed ore powder for smelting steel. A baffle 5 is fixedly connected to both sides of the upper end of the trolley 1. Connecting holes 7 are opened at the front and rear of the inner lower ends of the two baffles 5, and the edges at both ends of the connecting holes 7 are chamfered. A number of evenly distributed grate bars 6 are arranged on the upper end of the trolley 1 to sinter the materials carried by the trolley 1 to ensure that the ore is evenly sintered. The grate bars are made of refractory alloy steel, and baffles 202 are arranged at the front and rear of the inner lower end of the baffle 5. The sides of the baffles 202 away from each other are fixedly connected with plug rods 201, which are inserted into the inside of the connecting hole 7. The ends of the plug rods 201 away from each other extend from the inside of the connecting hole 7 to the side of the baffle 5 away from each other, and the grate bars 6 are pressed against the upper side of the trolley 1 through the baffles 202 to fix the grate bars 6.

[0035] In order to make the inner side of the baffle 202 and the baffle plate 5 fit tightly, a chamfer design is made at the connection between the baffle 202 and the plug rod 201, so that the connection between the baffle 202 and the plug rod 201 can fit tightly with the edge of one end inside the connecting hole 7, and a gasket 4 is arranged at the position where the connecting hole 7 is opened on the outside of the baffle plate 5, the gasket 4 is sleeved on the plug rod 201, and a pin hole 8 is opened at one end of the plug rod 201 passing through the gasket 4, and a pin hole 8 is opened inside each pin hole 8. After the pin rod 301 is inserted into the pin hole 8, the gasket 4 can be squeezed to the outside of the baffle plate 5, the baffle plate 5 is clamped by the baffle 202 and the gasket 4, and the plug rod 201 is fixed by the pin rod 301, so that the plug rod 201 can be conveniently disassembled and installed.

[0036] Embodiment 2:

[0037] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:

[0038] In order to fix the pin rod 301 and prevent the pin rod 301 from falling off due to the vibration of the trolley, an arc-shaped elastic ring 302 is hinged at the upper end of the pin rod 301. The arc-shaped elastic ring 302 is C-shaped, and one end of the arc-shaped elastic ring 302 is hinged to one end of the pin rod 301, and a hook-shaped slot 9 is provided on the other side edge of the arc-shaped elastic ring 302. The slot 9 can be used for the other end of the arc-shaped elastic ring 302 connected to the pin rod 301 to be inserted into. The connection between the slot 9 and the arc-shaped elastic ring 302 is respectively outside the two ends of the pin hole 8, and the arc-shaped elastic ring 302 is used to wrap the insertion rod 201.

[0039] After one end of the arc-shaped elastic ring 302 is inserted into the interior of the slot 9, the gasket 4 can be squeezed and fixed by the annular pin rod 301. When one end of the arc-shaped elastic ring 302 is taken out from the interior of the slot 9, the pin rod 301 can be taken out from the interior of the pin hole 8. At the same time, in order to increase the sealing between the gasket 4 and the baffle 5, a chamfered convex ring 10 is fixedly connected to the edge of the gasket 4 near one end of the baffle 5, which is matched with the chamfered convex ring 10 set on the connecting hole 7.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
