Description

Technical Field

[0001] The utility model relates to the technical field of sintered ore cooling treatment and metallurgical slag treatment equipment, in particular to a ring-shaped trolley driving device. Background Art

[0002] At present, the existing mobile trolleys of sintered ore cooling equipment mostly use a circular mobile transmission system driven by a motor and a reducer. The equipment is heavy, occupies too much space, and requires a huge civil engineering foundation structure and load-bearing requirements.

[0003] Metallurgical slag processing feeding trolleys mostly use a wire rope drum mechanism to drive the trolley to move back and forth in a straight line. The transmission actuator requires frequent maintenance, has poor transmission reliability, and low operating stability. Large mechanical shock fluctuations will be generated when starting. The transmission mechanism needs to be set in the direction of the trolley's operation, which increases the length and space occupied by the equipment. Utility Model Content

[0004] In order to solve the above problems in the prior art, the utility model provides a ring-shaped trolley driving device.

[0005] The utility model provides a ring trolley driving device adopting the following technical solutions:

[0006] A circular trolley drive device is arranged on the side of the circular trolley, including a drive frame, a drive motor is installed in the drive frame, a reducer is installed on the drive motor, a driving pin gear is installed on the reducer, and multiple driven pin shafts are installed on the peripheral wall of the circular trolley, and the driving pin gear and the driven pin shaft are engaged with each other.

[0007] By adopting the above technical solution and using a drive device in conjunction with the cooling system of the circular trolley, compared with the traditional motor and reducer drive, the weight of the equipment can be effectively reduced, the occupied space can be reduced, and the required civil engineering foundation specifications can be reduced; compared with the traditional wire rope driven linear motion system, the processing efficiency of the equipment is improved, the maintenance cycle of the transmission actuator is reduced, the transmission reliability and operation stability are improved, and the starting mechanical impact fluctuation is reduced; the maintenance points are reduced and it is not easily affected by environmental dust. The drive device is arranged on the side of the circular trolley to reduce the length and space occupied by the equipment.

[0008] Optionally, the reducer is installed on the top of the drive motor, and a buffer support car with a pulley is installed at the bottom of the drive motor. The pulley rolls in the direction of approaching or moving away from the driven pin shaft, and a buffer support frame for elastic buffering is provided between the rotating shaft where the active pin gear is located and the drive frame.

[0009] By adopting the above technical solution, the problem of the driven pin shaft hard colliding with the driving pin gear due to deflection during the rotation process is effectively alleviated.

[0010] Optionally, the buffer support frame includes a transverse guide cylinder, a transverse guide rod and a transverse spring. The transverse guide cylinder is installed on the rotating shaft. One end of the transverse guide rod is passed through the transverse guide cylinder and the other end is installed on the driving frame. The transverse spring is installed in the transverse guide cylinder. The transverse spring is elastically supported between the transverse guide cylinder and the transverse guide rod.

[0011] By adopting the above technical solution, the transverse guide cylinder and the transverse guide rod have the function of directional guidance, and the transverse spring has the function of elastic energy storage.

[0012] Optionally, the buffer support vehicle includes a vertical guide cylinder, a vertical guide rod and a vertical spring. The vertical guide cylinder is installed at the bottom of the drive motor, the vertical guide rod is installed at the top of the buffer support vehicle body, the vertical spring is installed in the vertical guide cylinder, and the vertical spring is elastically supported between the vertical guide cylinder and the vertical guide rod.

[0013] By adopting the above technical solution, the vertical spring can have a buffering effect on the active pin gear in the vertical direction.

[0014] Optionally, the drive motor is a hydraulic motor.

[0015] By adopting the above technical solution, the hydraulically driven pin gear transmission has no fluctuation factors, good stability and small impact. When the hydraulic drive encounters an overload of equipment for processing large materials, the excess load can be flexibly unloaded, effectively protecting the drive equipment and preventing overload damage. The adjustment range is large and the required speed can be achieved.

[0016] Optionally, the reducer is a planetary reducer.

[0017] By adopting the above technical solution, this type of operating system requires a very slow adjustable speed operating range, so a planetary reducer is provided to further reduce the speed of the drive motor.

[0018] Optionally, at least two driving devices are evenly arranged around the annular trolley.

[0019] In summary, the present invention has at least one of the following beneficial technical effects:

[0020] 1. The use of a drive device combined with the cooling system of the ring trolley can effectively reduce the weight of the equipment, reduce the occupied space, and reduce the required civil engineering foundation specifications compared to traditional motor and reducer drives;

[0026] The following is combined with Figure 1 -Attached Figure 2 The utility model is described in further detail.

[0027] The embodiment of the utility model discloses a ring-shaped trolley driving device. Figure 1 There are two driving devices 2 evenly arranged around the annular trolley 1, or multiple driving devices can be arranged, which can not only ensure the uniformity of the force of the annular trolley 1 during operation, but also ensure the synchronization of multi-drive operation. The driving device 2 is used to drive the annular trolley 1 to perform cyclic circular motion.

[0028] Reference Figure 2 The driving device 2 includes a driving frame 20, which is fixed to the ground. A driving motor 21 is installed in the driving frame 20. The driving motor 21 in this embodiment is a hydraulic motor; a reducer 22 is installed on the top of the driving motor 21. The reducer 22 in this embodiment is a planetary reducer; a driving pin gear 23 is installed on the top of the reducer 22, and the driving pin gear 23 is arranged horizontally; a plurality of vertically arranged driven pin shafts 24 are evenly installed on the peripheral wall of the annular trolley 1, and the driving pin gear 23 is engaged with the driven pin shaft 24, which can effectively prevent the annular trolley 1 from being deformed by force and dust from falling into the transmission pair to affect the operation.

[0029] Reference Figure 2 In order to alleviate the problem of the driven pin shaft 24 colliding hard with the active pin gear 23 due to deflection during the rotation process, a buffer support vehicle 25 with a pulley is installed at the bottom of the driving motor 21. The rolling direction of the pulley is set to approach or move away from the driven pin shaft 24, and the movement range is 0-10cm; a buffer support frame 26 is also installed between the driving frame 20 and the rotating shaft where the active pin gear 23 is located to elastically reduce the impact brought by the driven pin shaft 24.

[0030] Reference Figure 2The buffer support frame 26 includes a transverse guide cylinder 260, a transverse guide rod 261, and a transverse spring 262. The transverse guide cylinder 260 is mounted on the rotating shaft. One end of the transverse guide rod 261 passes through the transverse guide cylinder 260 and the other end is fixed to the driving frame 20. The transverse spring 262 is installed in the transverse guide cylinder 260 and elastically supported between the transverse guide cylinder 260 and the transverse guide rod 261. The transverse spring 262 has a tendency to elastically drive the driving pin gear 23 to move toward the driven pin shaft 24.

[0031] Reference Figure 2 The buffer support vehicle 25 includes a vertical guide cylinder 250, a vertical guide rod 251, and a vertical spring 252. The vertical guide cylinder 250 is mounted on the bottom of the drive motor 21, the vertical guide rod 251 is mounted on the top of the main body of the buffer support vehicle 25, and the vertical spring 252 is mounted inside the vertical guide cylinder 250. The vertical spring 252 is elastically supported between the vertical guide cylinder 250 and the vertical guide rod 251, and has a tendency to elastically drive the drive motor 21 to move upward.

[0032] The working principle of the annular trolley drive device of the embodiment of the present utility model is as follows: the driving motor 21 transmits power to the annular trolley 1 in sequence through the reducer 22, the active pin gear 23 and the driven pin shaft 24, thereby driving the annular trolley 1 to circulate in a circular motion. If there is a position deviation of part of the driven pin shaft 24 relative to the annular trolley 1, the driven pin shaft 24 pushes the active pin gear 23, which can drive the buffer support vehicle 25 to move away from the driven pin shaft 24 to avoid a hard collision between the two. The transverse spring 262 elastically compresses to store energy, and then releases the energy to drive the active pin gear 23 back to its original position. Similarly, the vertical spring 252 can buffer the active pin gear 23 in the vertical direction.

[0033] The use of the drive device 2 in conjunction with the cooling system of the circular trolley 1 can effectively reduce the weight of the equipment, reduce the occupied space, and reduce the required civil engineering foundation specifications compared to the traditional motor and reducer drive; compared with the traditional wire rope driven linear motion system, it improves the processing efficiency of the equipment, reduces the maintenance cycle of the transmission actuator, improves the transmission reliability and operation stability, and reduces the mechanical shock fluctuation at startup; reduces the number of maintenance points and is not easily affected by environmental dust. The drive device 2 is arranged on the side of the circular trolley 1 to reduce the length and space occupied by the equipment.

[0034] The above are all preferred embodiments of the present invention, and are not intended to limit the scope of protection of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the scope of protection of the present invention.
