[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0027] Reference Figures 1-5 This utility model provides a technical solution: a kiln car transfer device for a tunnel kiln, including a transfer track 1 and a kiln car body 2. A transfer car body 3 is slidably mounted on the transfer track 1. The cross-sectional shape of the transfer car body 3 is convex. A wheel adaptation mechanism is provided on the transfer car body 3, including a first slid groove 401 and a second slid groove 404. Four first slid grooves 401 are provided, located at the top of the horizontal end of the transfer car body 3. The four first slid grooves 401 are distributed in pairs around the central axis of the transfer car body 3. Ear plates 402 are slidably fitted inside the first slid grooves 401, and a horizontal moving plate 403 is fixed between every two ear plates 402. The second slid grooves 404 are slidably opened on the vertical end of the transfer car body 3, and two vertical moving plates 405 are slidably fitted inside the second slid grooves 404. The wheels of the kiln car body 2 are located on the two vertical moving plates 405. On plate 405, in the initial state, the height of the vertical moving plate 405 is the same as the height of the guide rail. By setting a wheel adaptation mechanism, the kiln car body 2 is moved from the guide rail to the vertical moving plate 405. At the same time, the two vertical moving plates 405 are moved up or down until the middle position of the wheel is the same as the top of the horizontal moving plate 403. Then, the two horizontal moving plates 403 are moved in opposite directions until both horizontal moving plates 403 are in contact with the wheel. The wheel is fixed by the close contact between the horizontal moving plate 403 and the wheel. The transfer car body 3 is transferred from the transfer track 1, thereby transferring the kiln car body 2. Compared with the prior art, when facing different types of kiln cars, it can adapt to wheels of different widths and heights, avoiding the problem of poor fixation of the kiln car body 2 due to wheel size issues and shaking during transfer.
[0028] Reference Figures 1-5A limiting groove 406 is provided on the side of the horizontal moving plate 403 near the vertical moving plate 405. A limiting block 407 is integrally formed on the vertical moving plate 405. The limiting block 407 is slidably sleeved inside the limiting groove 406. A bidirectional screw 408 is rotatably installed inside the transfer vehicle body 3. Two ear plates 402 are threadedly sleeved on both ends of the bidirectional screw 408. A limiting rod 409 is fixedly installed inside the transfer vehicle body 3. The other two ear plates 402 are slidably sleeved on the surface of the limiting rod 409. By setting the bidirectional screw 408, when the bidirectional screw 408 rotates, due to the threaded connection between the bidirectional screw 408 and the two ear plates 402, and the limiting cooperation of the limiting rod 409, the two horizontal moving plates 403 can move relative to each other or in opposite directions at the same time.
[0029] Reference Figures 1-5 A drive screw 410 is rotatably installed inside the second slide groove 404, and a limiting rod 411 is fixedly installed inside the second slide groove 404. A lifting frame 412 is sleeved between the drive screw 410 and the limiting rod 411. Two vertical moving plates 405 are slidably sleeved on the surface of the lifting frame 412. By setting the drive screw 410, when the drive screw 410 rotates, the lifting frame 412 moves upward or downward through the threaded connection between the drive screw 410 and the lifting frame 412, and the limiting cooperation of the limiting rod 411.
[0030] Reference Figures 1-5 A first motor 413 is installed on the right side of the transfer vehicle body 3. The output end of the first motor 413 is connected to the bidirectional lead screw 408. A second motor 414 is installed inside the transfer vehicle body 3. The output end of the second motor 414 is connected to the drive lead screw 410. By setting the first motor 413 and the second motor 414, the rotation drive source can be provided for the bidirectional lead screw 408 and the drive lead screw 410 respectively.
[0031] Reference Figures 1-5A positioning mechanism is provided on the vertical moving plate 405. The positioning mechanism includes several positioning cavities 501, which are arranged in a linear array on the top of the vertical moving plate 405. A positioning block 502 is slidably installed inside the positioning cavity 501, and a fixing block is fixedly installed on the top of the positioning cavity 501. One side of the positioning block 502 is arc-shaped, and the other side is vertical. By setting up the positioning mechanism, when the kiln car body 2 moves from the guide rail to the vertical moving plate 405, the wheel alignment is... The positioning block 502 is squeezed, causing it to move downward and retract into the positioning cavity 501. When the wheel intersects with the positioning block 502, the rebound force of the first spring 507 causes the positioning block 502 to pop out from the positioning cavity 501 until the wheel contacts the fixed block. At this time, the wheel is blocked by the positioning block 502 and cannot retract, so that the kiln car body 2 can remain stable during the movement of the vertical moving plate 405, preventing the kiln car body 2 from retracting and the vertical moving plate 405 from detaching.
[0032] Reference Figures 1-5 A transmission plate 503 is fixedly installed on one side of the positioning block 502. A cavity 504 is opened inside the vertical moving plate 405, and the transmission plate 503 extends into the cavity 504. A pressing plate 505 is slidably installed inside the cavity 504, and the pressing plate 505 is located above the transmission plate 503. A foot pedal 506 is installed on the pressing plate 505. A first spring 507 and a first telescopic rod are installed between the inner bottom wall of the positioning cavity 501 and the positioning block 502. The inner bottom wall of the cavity 504... A second spring 508 and a second telescopic rod are installed between the pressing plate 505 and the pressing plate 505. By setting the transmission plate 503, when the kiln car body 2 is transferred to the preset position by the transfer car body 3, the user steps down on the foot pedal 506, so that the pressing plate 505 presses several transmission plates 503 at the same time, driving the transmission plates 503 to move downward, thereby causing the transmission plates 503 to drive the positioning block 502 to move downward. At this time, the user can remove the kiln car body 2 from the vertical moving plate 405.
[0033] Specifically, the working process or working principle of this tunnel kiln car transfer device is as follows: During use, the kiln car body 2 is moved from the guide rail to the vertical moving plate 405. The wheels press against the positioning block 502, causing the positioning block 502 to move downwards and retract into the positioning cavity 501. When the wheels and positioning block 502 intersect, the rebound force of the first spring 507 causes the positioning block 502 to pop out of the positioning cavity 501 until the wheels contact the fixed block. At this point, the wheels are blocked by the positioning block 502 and cannot retract. The user then starts the second motor 414, driving the drive screw 410 to rotate. Through the threaded connection between the drive screw 410 and the lifting frame 412, and the limiting action of the limiting rod 411, the lifting frame 412 moves upwards or downwards until the middle position of the wheels is aligned with the top of the horizontal moving plate 403. Then, the first motor 413 is started, driving the double... Rotating the lead screw 408 causes the two horizontal moving plates 403 to move in opposite directions simultaneously due to the threaded connection between the two-way lead screw 408 and the two ear plates 402, as well as the limiting action of the limiting rod 409. This continues until both horizontal moving plates 403 are in contact with the wheels. The wheels are then fixed in place by the tight contact between the horizontal moving plates 403 and the wheels, thus transferring the transfer car body 3 from the transfer track 1 and transferring the kiln car body 2. Once the kiln car body 2 has been transferred to the preset position by the transfer car body 3, the user steps down on the foot pedal 506, causing the pressing plate 505 to press down on several transmission plates 503 simultaneously. This causes the transmission plates 503 to move downwards, which in turn causes the positioning block 502 to move downwards, returning the horizontal moving plates 403 and the vertical moving plates 405 to their original positions. At this point, the user can remove the kiln car body 2 from the vertical moving plate 405.
