Description

Technical Field

[0001] The utility model relates to the field of kiln cars for kilns, and more specifically, to a refractory high-temperature kiln car track replacement vehicle. Background Technique

[0002] There are many types of refractory materials, including clay refractory bricks which are widely used. When they are formed, they need to be calcined at a high temperature in a high-temperature kiln. To improve the convenience of feeding and discharging the clay refractory brick blanks inside the high-temperature kiln, generally, the kiln cars are pre-stacked and then pushed into the high-temperature kiln together for calcination. However, most of the track wheels of the existing kiln cars are directly installed at the bottom of the bracket of the kiln car through a connecting shaft and a shaft seat. During the calcination process, there is a lack of a corresponding mechanism to unload the connecting shaft connecting the track wheels, so that during the calcination process, the connecting shaft connecting the track wheels not only has to bear the overall weight of the clay refractory brick blanks placed on the bracket, but also has to bear the high temperature inside the high-temperature kiln, which increases the probability of thermal deformation of the connecting shaft of the track wheels. Over time, it is not conducive to the smooth movement of the track wheels of the kiln car on the laid tracks. Therefore, we propose a refractory high-temperature kiln car track replacement vehicle to solve the above existing problems. Content of the Utility Model

[0003] 1. Technical Problems to be Solved

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a refractory high-temperature kiln car track replacement vehicle. Its support mechanism arranged at the bottom of the chassis bracket can be adjusted by rotating the adjusting rod. That is, when it is necessary to move the kiln car track replacement vehicle, rotating the adjusting rod can pull the whole bracket towards the handle side, and then pull all the racks connected thereto to move towards the handle side, prompting the gear to rotate in the opposite direction, and then driving the crank arm and the track wheel to gradually rise, so as to facilitate the track wheel to move on the pre-buried track inside the high-temperature kiln. When the kiln car track replacement vehicle moves to the inside of the high-temperature kiln and it is necessary to carry out high-temperature calcination on the clay refractory brick blanks, only need to rotate the adjusting rod in the reverse direction to prompt the crank arm and the track wheel to gradually descend, and make the base vertical rod support at the bottom of the inner wall of the high-temperature kiln. Transfer the weight of the clay refractory brick blanks stacked on the chassis bracket to the base vertical rod and support it at the bottom of the inner wall of the high-temperature kiln, reduce the load on the shaft of the track wheel, and then reduce the probability of thermal deformation of the shaft of the track wheel, which is beneficial to the smooth movement of the track wheel on the laid track in the later stage.

[0012] 3. Beneficial effects

[0013] Compared with the prior art, the advantages of the present invention are:

[0014] In this solution, the support mechanism arranged at the bottom of the chassis bracket can be adjusted by rotating the adjusting rod, that is, when the kiln car track replacement car needs to be moved, the adjusting rod can be rotated to pull the bracket as a whole toward the handle side, thereby pulling all the racks connected thereto to move toward the handle side, causing the gears to rotate in the opposite direction, thereby driving the crank arm and the track wheel to be gradually raised, so as to facilitate the track wheel to be stuck on the track embedded in the high-temperature kiln and move. When the kiln car track replacement car moves to the inside of the high-temperature kiln and needs to perform high-temperature calcination on the clay refractory brick embryo, it is only necessary to rotate the adjusting rod in the opposite direction to cause the crank arm and the track wheel to gradually descend, and support the base uprights on the bottom of the inner wall of the high-temperature kiln, so that the weight of the clay refractory brick embryo stacked on the chassis bracket is transferred to the base uprights and supported on the bottom of the inner wall of the high-temperature kiln, thereby reducing the load at the crank arm connection on the track wheel, thereby reducing the probability of thermal deformation at the crank arm connection on the track wheel, which is conducive to the smooth movement of the track wheel on the laid track in the later stage.

[0025] An ear seat 4 is fixedly welded on the chassis bracket 1, and an adjusting rod 5 is rotatably connected inside the ear seat 4. An outer wall of one end of the adjusting rod 5 is provided with an external thread structure, and an ear seat 2 6 is threadedly connected to the outer wall of one end of the adjusting rod 5. The bottom of the ear seat 2 6 is fixedly welded on the bracket 3.

[0026] The operating principle of this refractory high temperature kiln kiln car track replacement vehicle is:

[0027] First, Figure 1 The vehicle body structure as shown is turned over as a whole downward, so that the four track wheels 208 are just stuck on the track embedded inside the high-temperature kiln, and then the clay refractory brick body is stacked on the chassis bracket 1. At this time, the adjusting rod 5 is rotated to pull the bracket 3 as a whole toward the handle 501 side, thereby pulling all the racks 202 connected thereto to move toward the handle 501 side, causing the gear 204 to rotate in the opposite direction, thereby driving the crank arm 207 and the track wheel 208 to gradually rise, thereby facilitating the track wheel 208 to move on the track embedded inside the high-temperature kiln. When the kiln car track replacement car moves When the clay refractory brick body needs to be calcined at high temperature inside the high-temperature kiln, it is only necessary to reversely rotate the adjusting rod 5 to cause the curved arm 207 and the track wheel 208 to gradually descend, and support the base upright 206 on the bottom of the inner wall of the high-temperature kiln. The weight of the clay refractory brick body stacked on the chassis bracket 1 is transferred to the base upright 206 and supported on the bottom of the inner wall of the high-temperature kiln, thereby reducing the load on the connection between the curved arm 207 on the track wheel 208, thereby reducing the probability of thermal deformation of the connection between the curved arm 207 on the track wheel 208, thereby facilitating the smooth movement of the track wheel 208 on the laid track in the later stage.

[0028] Embodiment 2:

[0029] In view of the above embodiment 1, for further description, refer to Figure 3 , Figure 4 as well as Figure 5, a T-shaped sliding groove 2011 is formed on the cross beam 201. T-shaped connecting ends 2021 are fixedly connected to the bottoms of the racks 202. The bottoms of the racks 202 are slidably connected to the corresponding cross beam 201 through the T-shaped connecting ends 2021 and the T-shaped sliding groove 2011;

[0030] By providing the T-shaped sliding groove 2011 and the T-shaped connecting end 2021, a connecting structure can be provided between the cross beam 201 and the rack 202, and it can ensure that the rack 202 slides reciprocally in a fixed direction on the cross beam 201.

[0031] The distance between the outer edge of the track wheel 208 and the axis of the rack 202 is greater than the distance between the top of the base vertical rod 206 and the axis of the rack 202. A handle 501 is fixedly installed at one end of the adjusting rod 5.

[0032] By making the distance between the outer edge of the track wheel 208 and the axis of the rack 202 greater than the distance between the top of the base vertical rod 206 and the axis of the rack 202, after the crank arm 207 is adjusted to the vertical state, the track wheel 208 can support the chassis bracket 1 through the crank arm 207, and the bottom of the base vertical rod 206 can be disengaged from the contact with the bottom of the inner wall of the high-temperature kiln, so as to facilitate the realization of the moving function.
