Specific embodiments

[0027] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present invention.

[0028] Refer to Figures 1 - 4 , the present invention provides a technical solution:

[0029] Embodiment:

[0030] As Figures 1 - 4 shown, a horizontal turning device for curing a fireproof door core material includes a carrying platform 1, a base 2 and a turntable 3. An installation hole is provided in the middle of the carrying platform 1, and two perpendicular fixed rails 4 are provided at the edge of the carrying platform 1;

[0031] The base 2 is arranged in the installation hole, the turntable 3 is rotationally connected to the base 2 through a connecting member, and the turntable 3 is driven by a first driving assembly;

[0032] A moving rail 5 adapted to the rollers of the pouring trolley 21 is provided on the turntable 3. The moving rail 5 corresponds to the two fixed rails 4 respectively before and after the rotation of the turntable 3 (here, corresponding means end-to-end connection); a second driving assembly for driving the pouring trolley 21 is provided between the moving rails 5.

[0033] Working principle: During transfer, the pouring trolley 21 is first transferred from the upper station to the moving rail 5 on the turntable 3 through one of the fixed rails 4 (before transfer, ensure that the moving rail 5 on the turntable 3 corresponds to this fixed rail 4).

[0034] Then start the first driving assembly, and the first driving assembly drives the turntable 3 to rotate 90 degrees until the moving rail 5 corresponds to the other fixed rail 4. At this time, drive the pouring trolley 21 to run towards this fixed rail 4 through the second driving assembly (this fixed rail 4 is arranged towards the transfer channel) until the pouring trolley 21 moves onto the ferry vehicle in the transfer channel; then the first driving assembly drives the turntable 3 to reset.

[0035] The utility model realizes the horizontal direction change of the pouring trolley 21 by setting a bearing table 1, a base 2 and a turntable 3, replacing manual labor with machinery, and greatly improving the transfer efficiency of the pouring trolley 21.

[0036] Further, as Figure 2 and Figure 3 shown, the connecting piece includes a mounting column 6 fixedly arranged on the base 2 and a gear ring 7 rotatably connected to the outside of the mounting column 6;

[0037] The first driving assembly includes a first driving motor 8, and a driving gear 9 meshing with the gear ring 7 is arranged on the output shaft of the first driving motor 8;

[0038] The turntable 3 is fixedly connected to the top of the gear ring 7 through an annular plate 22 (the annular plate 22 is fixedly arranged at the bottom of the turntable 3).

[0039] Among them, the overall weight of the turntable 3 is supported by the gear ring 7. The rotation process is as follows: the first driving motor 8 drives the gear to rotate, the gear drives the gear ring 7 of the mechanism to rotate, and the gear ring 7 drives the annular plate 22 fixed to its top to rotate, thereby driving the turntable 3 to rotate synchronously.

[0040] Further, as Figures 2 - 4 shown, the second driving assembly includes a second driving motor 10 arranged on the turntable 3, a friction wheel 11 is connected to the output shaft of the second driving motor 10, and the friction wheel 11 protrudes from the upper surface of the moving rail 5;

[0041] A friction belt 12 is arranged at the bottom of the pouring trolley 21, and the friction belt 12 is adapted to the friction wheel 11.

[0042] The second driving motor 10 drives the friction wheel 11 to rotate. When the friction wheel 11 rotates, the pouring trolley 21 is driven to move towards the fixed rail 4 through the friction belt 12. The friction wheel 11 and the friction belt 12 cooperate to drive the pouring trolley 21, which can avoid a rigid connection with the turntable 3 while ensuring the effective driving of the pouring trolley 21, thereby facilitating the pouring trolley 21 to leave the turntable 3.

[0043] Further, limiting blocks 13 are arranged at two diagonal corners of the base 2. The arranged limiting blocks 13 are used to prevent the turntable 3 from rotating excessively.

[0044] Further, as Figure 3 shown, two sensors 14 are arranged on the base 2, and the sensors 14 are respectively arranged corresponding to the two fixed rails 4 up and down;

[0045] A Z-shaped signal plate 15 is provided on the ring plate 22. The signal plate 15 corresponds to two sensors 14 respectively before and after the turntable 3 rotates. Among them, the sensor 14 is an inductive or capacitive sensor 14. The signal plate 15 is made of a metal material. The sensor 14 cooperates with the signal plate 15 to detect whether the turntable 3 rotates in place. If the sensor 14 senses the signal plate 15, it means that the rotation is in place; otherwise, the turntable 3 is not in place.

[0046] Further, a vertical baffle 16 is provided at one end of the moving rail 5 away from the fixed rail 4. The provided baffle 16 is used to prevent the trolley from moving excessively and detaching from the moving rail 5.

[0047] Further, as Figure 3 and Figure 4 shown, the friction wheel 11 is connected to the connecting plate 17 through the first ear plate. The connecting plate 17 is of an inverted U-shaped structure. One end of the connecting plate 17 is connected to the base 2 through a rotating shaft and two second ear plates 18 (where the rotating shaft is rotatably connected to the second ear plate 18). The other end of the connecting plate 17 is movably connected to the base 2 through a telescopic member.

[0048] The telescopic member includes a connecting rod 19. The top end of the connecting rod 19 freely extends from the connecting plate 17 (where a relief groove is provided on the connecting plate 17, the top of the connecting rod 19 extends from the relief groove, and two gaskets are movably sleeved on the connecting rod 19, and the connecting plate 17 is clamped between the two gaskets; the bottom of the connecting rod 19 is fixedly connected to the base 2); two nuts are provided on the connecting rod 19, and a spring 20 is coaxially sleeved outside the connecting rod 19. The two ends of the spring 20 are respectively abutted against the two nuts.

[0049] The friction wheel 11 is movably connected to the base 2 through the connecting plate 17. In this way, when the pouring trolley 21 just contacts the friction wheel 11, the friction wheel 11 is squeezed, and then the spring 20 is compressed to make one end of the connecting plate 17 move downward. When the pouring trolley 21 is in full contact with the friction wheel 11, the friction wheel 11 resets. This can avoid the pouring trolley 21 colliding with the friction wheel 11 (reducing the hard contact between the two) and damaging the friction wheel 11.

[0050] The above are only the preferred embodiments of the present invention. It should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge in related fields. And the modifications and changes made by those skilled in the art that do not depart from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
