DETAILED DESCRIPTION

[0048] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0049] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the present invention. As used herein, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components and / or combinations thereof.

[0051] Unless otherwise specifically stated, the relative arrangement of the parts and steps described in these embodiments, the numerical expressions and numerical values ​​do not limit the scope of the present invention. At the same time, it should be clear that, for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0052] In the description of the present invention, it is necessary to understand that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings. They are only for the convenience of describing the present invention and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the scope of protection of the present invention: the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0053] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below their position devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0054] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the present invention.

[0055] like Figure 1-12 As shown, the present invention provides a coke tank crane operating mechanism, comprising: a high-speed shaft driving device, an operating reducer and a transmission assembly;

[0056] One input end on each side of the running reducer in the left and right directions is connected to the output end of the high-speed shaft driving device;

[0057] The two output ends on both sides of the running reducer in the left and right directions are connected to the input end of the transmission component;

[0058] The output end of the transmission assembly is connected to the input end of the trolley group 13 .

[0059] When the high-speed shaft drive device is a parallel shaft reducer 4 emergency model or a parallel shaft reducer 4 hot standby model, the operating reducer is the parallel shaft reducer 4;

[0060] The parallel shaft reducer 4 emergency model includes a motor 1, a brake wheel / disc coupling 2, a brake 3, a brake wheel / disc 7, a clutch 6 and a reduction motor 5; the two sets of drive devices are respectively arranged on both sides of the input shaft of the ordinary reducer 10. When the main drive device motor 1 fails, the clutch 6 is closed and the emergency drive device completes a working cycle at a low speed.

[0061] On one side of the parallel shaft reducer 4 in the left and right direction, the output end of the motor 1 is connected to the input end of the brake wheel / disk coupling 2, the output end of the brake wheel / disk coupling 2 is connected to the input end of the brake 3, and the output end of the brake 3 is connected to the input end of the parallel shaft reducer 4;

[0062] On the other side of the parallel shaft reducer 4 in the left and right direction, the output end of the reduction motor 5 is connected to the input end of the clutch 6, the output end of the clutch 6 is connected to the input end of the brake 3, the output end of the brake 3 is connected to the input end of the brake wheel / disc 7, and the output end of the brake wheel / disc 7 is connected to the input end of the parallel shaft reducer 4; the motor 1, brake 3, clutch 6 and reduction motor 5 are fixed with base bolts and welded to the main structure frame of the coke tank crane.

[0063] The parallel shaft reducer 4 hot standby model includes an electric motor 1, a brake wheel / disc coupling 2 and a brake 3; two sets of drive devices are arranged on both sides of the input shaft of the common reducer respectively. When one of the electric motors 1 fails, the drive of the other electric motor 1 can still run at normal high and low speeds for a long time.

[0064] On both sides of the parallel shaft reducer 4 in the left and right directions, the output end of the motor 1 is connected to the input end of the brake wheel / disc coupling 2, the output end of the brake wheel / disc coupling 2 is connected to the input end of the brake 3, and the output end of the brake 3 is connected to the input end of the parallel shaft reducer 4; the motor 1 and the brake 3 are fixed to the base bolts and welded to the main structure frame of the coke tank crane.

[0065] When the high-speed shaft drive device is a planetary reducer 8 model, the operating reducer is a planetary reducer 8;

[0066] The planetary reducer 8 model includes an electric motor 1, a brake wheel / disc coupling 2 and a brake 3; two sets of drive devices are respectively arranged on both sides of the input shaft of the planetary reducer 8. When one of the electric motors 1 fails, the drive of the other electric motor 1 can still run at half speed for a long time (high speed is halved and low speed remains unchanged).

[0067] On both sides of the planetary reducer 8 in the left and right directions, the output end of the motor 1 is connected to the input end of the brake wheel / disc coupling 2, the output end of the brake wheel / disc coupling 2 is connected to the input end of the brake 3, and the output end of the brake 3 is connected to the input end of the planetary reducer 8; the motor 1 and the brake 3 are fixed to the base bolts and welded to the main structure frame of the coke tank crane.

[0068] The track gauge is the distance from the left wheel center to the right wheel center of the coke tank crane. If the track gauge is too long, the transmission shaft will be too long. When the transmission shaft is too long, the natural frequency will be reduced and resonance will be generated. Therefore, a track gauge greater than 13.6m is considered too long.

[0069] When the track gauge is ≤ the excessive track gauge, the transmission assembly from the operating reducer to the trolley group adopts the first arrangement scheme;

[0070] The first arrangement is as follows:

[0071] The transmission assembly includes a first full-tooth coupling 9, a second full-tooth coupling 12, a first transmission shaft 11 and a supporting device 10; two output ends are respectively arranged on the left and right sides of the parallel shaft reducer 4, the output end of the parallel shaft reducer 4 is connected to the input end of the first full-tooth coupling 9, the output end of the first full-tooth coupling 9 is connected to the input end of the first transmission shaft 11, the output end of the first transmission shaft 11 is connected to the input end of the second full-tooth coupling 12, and the output end of the second full-tooth coupling 12 is connected to the input end of the trolley group 13; the first transmission shaft 11 is arranged on the supporting device 10.

[0072] When the track gauge is greater than the excessively long track gauge, the transmission assembly from the operating reducer to the bogie group adopts the second arrangement scheme.

[0073] The second arrangement is as follows:

[0074] The transmission assembly includes a first half-tooth coupling 16, a second half-tooth coupling 18, a second transmission shaft 15, a third transmission shaft 17 and a full-tooth coupling; two output ends are respectively arranged on the left and right sides of the planetary reducer 8, the output end of the planetary reducer 8 is connected to the input end of the third full-tooth coupling 14, the output end of the third full-tooth coupling 14 is connected to the input end of the second transmission shaft 15, the output end of the second transmission shaft 15 is connected to the input end of the first half-tooth coupling 16, the output end of the first half-tooth coupling 16 is connected to the input end of the third transmission shaft 17, the output end of the third transmission shaft 17 is connected to the input end of the second half-tooth coupling 18, and the output end of the second half-tooth coupling 18 is connected to the input end of the trolley group 13; the second transmission shaft 15 is arranged on the supporting device 10.

[0075] When the coke tank crane adopts a half-drive scheme, the operating mechanism is arranged on one side of the coke tank crane in the front and rear directions;

[0076] When the coke tank crane adopts the full-drive solution, the operating mechanism is arranged on both sides of the coke tank crane in the front and rear directions;

[0077] Fig.13 , 14 It is a schematic diagram of the device when the track gauge is ≤ the excessive track gauge, the half-drive scheme is adopted, and the high-speed shaft drive device adopts a parallel shaft reducer emergency model.

[0078] Fig.15 , 16 This is a schematic diagram of the device when the track gauge is greater than the excessively long track gauge, the full drive scheme is adopted, and the high-speed shaft drive device adopts a planetary reducer model.

[0079] The high-speed shaft drive device corresponds to different operating reducers according to the difference in control systems. The transmission components from the operating reducer to the trolley group are selected according to the track gauge size. The operating mechanism is arranged on one side or both sides according to customer requirements.

[0080] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
