Description

Technical Field

[0001] The utility model relates to the technical field of coal mining machines, in particular to a cooling structure of a rocker arm of a coal mining machine. Background Art

[0002] Coal mining machine is one of the important equipment to realize the mechanization and modernization of coal mine production. Mechanized coal mining can reduce physical labor, improve safety, and achieve the goals of high output, high efficiency and low consumption. In order to ensure that the coal mining machine has sufficient ability to cut and clamp gangue and pass faults, the rocker arm cutting power is usually designed to be relatively sufficient to expand its adaptability. However, the adverse effect of the sufficient power design is that the temperature of the gear transmission cavity inside the rocker arm is too high.

[0003] Therefore, to ensure the safe and reliable operation of the coal mining machine, the cooling structure of the coal mining machine rocker arm is very important. However, the existing arrangement of the rocker arm waterway cannot meet the cooling requirements of the high power density rocker arm. Summary of the invention

[0004] The utility model aims to solve the above problems and provides a cooling structure for a rocker arm of a coal mining machine.

[0005] The purpose of the utility model is achieved in this way:

[0006] A cooling structure for a rocker arm of a coal mining machine, comprising:

[0007] A cooling water channel is arranged on the shell of the rocker arm of the coal mining machine, an edge boss is arranged along the edge of the cooling water channel, and a nozzle is also arranged on the cooling water channel.

[0008] Wherein, an intermediate boss is also provided on the center line close to the cooling water channel.

[0009] Wherein, the cooling water channel is in the shape of an elongated strip, and the edge bosses are arranged on both side edges of the cooling water channel along the length direction of the cooling water channel.

[0010] Wherein, the middle boss and the nozzle are arranged at intervals.

[0011] Wherein, the middle boss is circular and the edge boss is semicircular.

[0012] The beneficial effects of the utility model are as follows: the utility model changes the flow direction of water in the cooling water channel by arranging an edge boss at the edge of the cooling water channel, and at the same time can also play a role in slowing down the flow speed of the water. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 The utility model shows a schematic diagram of a cooling structure of a rocker arm of a coal mining machine according to an embodiment of the present invention.

[0014] The following are the descriptions of the reference numerals:

[0016] 2-Edge boss;

[0017] 3-middle boss;

[0018] 4- Nozzle. DETAILED DESCRIPTION

[0019] Various embodiments of the present invention will be described with reference to the accompanying drawings. In the specification and the accompanying drawings, elements with similar structures or functions will be represented by the same element symbols. It is understood that the accompanying drawings are only for reference and illustration purposes and are not intended to limit the present invention. The dimensions shown in the accompanying drawings are only for the convenience of clear description, and do not limit the proportional relationship or provide an exhaustive description of the present invention, nor do they limit the scope of the present invention.

[0020] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] The utility model discloses a cooling structure of a rocker arm of a coal mining machine. Figure 1 The utility model shows a schematic diagram of a cooling structure of a rocker arm of a coal mining machine according to an embodiment of the present invention.

[0022] like Figure 1 As shown, a cooling structure of a rocker arm of a coal mining machine includes a cooling water channel arranged on the housing of the rocker arm of the coal mining machine, an edge boss is arranged along the edge of the cooling water channel, and a nozzle is also arranged on the cooling water channel. Preferably, an intermediate boss is also arranged near the center line of the cooling water channel.

[0023] In a specific embodiment, the cooling water channel can be in the shape of a long strip, and the edge bosses are arranged on the edges of both sides of the cooling water channel along the length direction of the cooling water channel. The edge bosses, the middle bosses, and the nozzles can be arranged in a plurality, preferably, the middle bosses and the nozzles are arranged at intervals, the middle bosses are circular, and the edge bosses are semicircular.

[0024] Among them, the cooling water channels are distributed in the upper and lower parts of the coal mining machine rocker arm and are connected. The cooling water flows through the cooling water channel on the upper part of the rocker arm to the cooling water channel on the lower part of the rocker arm, and then flows back to the upper part of the rocker arm and is sprayed out through the nozzle. The flowing water continuously takes away the heat, thereby improving the cooling effect of the rocker arm and improving the reliability of the rocker arm. By adding edge bosses and / or middle bosses to change the flow direction of water in the cooling water channel, it can also play a role in delaying the flow speed of the water, thereby achieving a better cooling effect.

[0025] Although the specific implementations of the utility model are described above, those skilled in the art should understand that this is only an example, and the protection scope of the utility model is defined by the attached claims. Those skilled in the art can make various changes or modifications to these implementations without departing from the principle and essence of the utility model, but these changes and modifications fall within the protection scope of the utility model.
