[0037] The bracket provided in this embodiment includes a first supporting member 02, a second supporting member 01 and a flow channel. Figures 1 to 6 The structures and working principles of the aforementioned components are described in detail.

[0038] like Figure 1 As shown, Figure 1 A schematic diagram of an axonometric view of a gearbox mechanism provided in this embodiment is shown, and the above-mentioned bracket and the gearbox supported by the bracket are shown in the schematic diagram. In this embodiment, as an example, the gearbox in this embodiment can be a cutting gearbox.

[0039] Based on the characteristics described above, see Figure 1 In this embodiment, the bracket includes a first support member 02 for supporting the cutting gear box, and further includes a second support member 01 connected to the first support member 02. The first support member 02 includes two first wall portions 18 (see the second wall portion 19) facing each other. Figure 3 ), the gear box is supported between the two first wall portions 18; the first supporting member 02 also includes a second wall portion 19, and the second wall portion 19 is connected to both first wall portions 18.

[0040] In an embodiment, the gearbox is supported by two first wall portions 18 in the following manner. Specifically, the first wall portion 18 may include a first portion and a second portion that are detachably connected, and the first portion and the second portion may be used to define a retaining member such as a bearing that supports the gearbox. See further Figure 1Taking the first wall portion 18 located on the left side as an example, the first part of the first wall portion 18 can be connected to the left side edge of the second wall portion 19, and the second part of the first wall portion 18 can be formed as a bearing cover 03, and both parts are formed with a semicircular retaining portion, thereby defining the above-mentioned bearing. Further, in an embodiment, the first part of the two first wall portions 18 and the second wall portion 19 can be formed into an integral structure, for example, the three can be obtained by casting and machining.

[0041] In an embodiment, at least a portion of the flow channel is disposed inside the support, and the flow channel is formed with an end portion exposed to the environment in which the support is located. Figures 1 to 6 In the example given, a portion of the flow passage is disposed inside the first support member 02, and another portion of the flow passage is disposed inside the second support member 01. However, it is not limited thereto, and although not shown in the figure, the entire flow passage may extend inside the first support member 02.

[0042] Since at least part of the flow channel is arranged inside the bracket, the interference of the harsh dust environment on the flow channel is greatly reduced, which ensures that the flow channel can have good anti-interference ability even in a harsh dust environment. More preferably, the two parts of the flow channel are respectively located inside the first support member 02 and the second support member 01, so that the flow channel has the maximum anti-interference ability. Furthermore, a fluid such as water can be transported from the end to the environment where the bracket is located, thereby effectively suppressing the generation of dust, reducing the overall temperature of the working condition and effectively improving environmental safety.

[0043] Combination Figures 1 to 3 See especially Figure 3 The portion of the flow channel located at the second support member 01 includes a plurality of inlets formed in the second support member 01. Specifically, the second support member 01 can be formed in a plate shape and detachably covered on the top of the second wall portion 19 by means of screws 09, and two reinforcing ribs are respectively provided between the bottom of the second support member 01 and the two sides of the first support member.

[0044] Still see Figure 3 , Figure 3 The connection between the partial flow channel in the second wall portion 19 on the left and the partial flow channel in the second support member 01 is specifically shown. The cross-sectional view is obtained by cutting along a vertical plane passing through the axis of the guide portion 05 described below. In an embodiment, the portion of the flow channel located in the second support member 01 can be formed as a guide portion 05 extending in the horizontal direction (that is, the guide portion 05 is formed as a channel, and the "guide hole" and "flow section" mentioned below can also be a channel), and multiple inlets formed in the second support member 01 are connected to the guide portion 05 for inputting fluid. The guide portion 05 is also formed with intermediate openings near both ends in the horizontal direction, and the two intermediate openings respectively connect the guide portion 05 with the portion of the flow channel located on both sides of the second wall portion 19.

[0045] See also Figure 3 , part of the flow channel in the second wall portion 19 includes a first flow guide hole 06 extending in the vertical direction and a second flow guide hole 07 extending in the horizontal direction and communicating with the first flow guide hole 06. The first flow guide hole 06 is formed in a stepped hole shape, and a sealing ring is provided between its upper end and the above-mentioned intermediate opening to achieve sealed communication. The second flow guide hole 07 extends inward from the left end surface of the second wall portion 19 to communicate with the first flow guide hole 06, and a screw plug 08 is installed at the left end of the second flow guide hole 07 to form a sealed state.

[0046] In the embodiment, the first guide hole 06 and the second guide hole 07 play a transition role between the portion of the flow channel located on the second supporting member 01 and the third flow section described below. Specifically, the two are drilled from the upper end face and the left end face of the second wall portion 19, respectively. The left end of the second guide hole 07 can be sealed by a screw plug 08, which ensures the feasibility of the processing technology and is also conducive to mass production.

[0047] Combination Figures 3 to 5 The portion of the flow passage located at the first support member 02 also includes a first flow portion and a second flow portion that are connected to each other, and the first flow portion is connected to multiple ends. The second flow portion can be located in the first portion of the first wall portion 18, and the first flow portion can be located in the bearing cover 03. The first flow portion is connected to the above-mentioned multiple ends, and the second flow portion is located between the second guide hole 07 and the first flow portion. Figure 3 In particular, the cross section of the third flow section 14 of the second flow portion is shown (not marked in the figure), that is, the circular hole near the left end of the second flow guide hole 07.

[0048] Further, Figure 4 A schematic diagram showing a top view of a gear mechanism, Figure 5 The schematic diagram showing the cross-sectional view of the BB section is obtained by cutting with a vertical plane passing through the axis of the second flow section. See in particular Figure 5 , Figure 5 The third flow segment 14 extending in the horizontal direction and the second flow segment 15 connected to the third flow segment 14 are shown, wherein the circular hole near the middle of the third flow segment 14 is the cross section of the second flow guide hole 07. In the embodiment, the third flow segment 14 is located at the second wall portion 19, and the second flow segment 15 may be mostly located at the first part of the first wall portion 18, and a small part is located at the second wall portion 19. However, although not shown in the figure, in fact, the second flow segment may also be completely located at the first part of the first wall portion 18.

[0049] In the embodiment, the second flow segment 15 is inclined along one side of the first wall portion 18, and can be drilled from the surface of the first part of the first wall portion 18 that interfaces with the second part into the first part of the first wall portion 18. Similarly, the third flow segment 14 can be drilled from the rear side of the second wall portion 19 (i.e. Figure 5 The third flow segment 14 and the second flow segment 15 are drilled into the second wall portion 19 on the right side, and the opening on the rear side can be sealed with a screw plug 08. Furthermore, the third flow segment 14 and the second flow segment 15 intersect with each other. The purpose of this arrangement is that the rear side of the second wall portion 19 is usually a rough surface, so the length of the third flow segment 14 is not easy to accurately calculate. In this regard, the third flow segment 14 and the second flow segment 15 are directly intersected with each other in this embodiment, which greatly saves design and processing procedures. In addition, it should be noted that when the third flow segment 14 and the second flow segment 15 intersect with each other, the second flow segment 15 is obviously mostly located in the first part of the first wall portion 18, and a small part is located in the second wall portion 19.

[0050] like Figure 5 As shown, the second flow section also includes a first flow section 16 located at the bearing cover 03. The first flow section 16 can be drilled into the bearing cover 03 from the end surface of the bearing cover 03 that is connected to the first part of the first wall portion 18. In the embodiment, the first flow section 16 and the second flow section 15 can be centered or misaligned with each other. When the two are centered, it is beneficial to further improve the fluid conveying efficiency. When the two are misaligned, it is beneficial to ensure that the original connection relationship between the bearing cover 03 and the first part of the first wall portion 18 is stable. Figure 5 It is this misalignment that is shown in FIG.

[0051] Still see Figure 5 The first wall portion 18 is formed with a plurality of teeth arranged along an arc, and the first flow portion is formed as a groove portion 17 concentric with the arc, with an end portion located between two adjacent teeth. As an example, Figure 5 8 ends are shown in FIG. The first support member 02 also includes a pressing member, which can be formed, for example, as a pressing plate 04 ( Figure 6 ), the seal is crimped onto the outside of the groove 17.

[0052] like Figure 6 As shown and will be combined Figure 5, the pressing plate 04 is mounted on the bearing cover 03 via a plurality of screws 09. A closed sealing groove 13 is arranged around the groove 17, and an O-ring 10 is arranged in the sealing groove 13. When the pressing plate 04 is mounted on the bearing cover 03, the O-ring 10 abuts against the pressing plate 04, thereby achieving sealing of the groove 17. Further, the end is formed as a nozzle mounting hole 12 and communicates with the groove 17, and the interior of the end is screwed into the nozzle 11, so that a fluid such as water is sprayed toward the environment. In the embodiment, the arc-shaped groove 17 is particularly conducive to the arrangement of the adapted teeth, and the water can be sprayed evenly in conjunction with the distribution position of the end, thereby further suppressing the generation of dust. In addition, the arrangement of the pressing plate 04 allows the arc-shaped groove 17 to be processed openly (for example, by milling) and then sealed. In other words, this is conducive to the molding of the arc-shaped groove 17.

[0053] The bracket provided in this embodiment is mostly processed with internal holes, which is easy to process and manufacture, with low cost and good economic benefits. Because the spray water channel structure is safe and reliable, the pressure is stable and is not interfered by external factors, and the anti-interference ability is strong. At the same time, it does not affect the appearance of the overall structure. The bracket provided in this embodiment effectively suppresses the generation of dust, reduces the ambient temperature, keeps the environment clean, and can greatly improve the safety of the production environment.

[0054] This embodiment also provides a gear box mechanism, including the above bracket and a cutting gear box. The gear box mechanism can be applied to an anchor mining machine.
