[0041] Combine the following Figures 1 to 5 , describing an embodiment of the utility model.

[0042] According to an embodiment of the utility model, on the one hand, a boom valve installation structure is provided, comprising:

[0043] A wheel cover 31, wherein a receiving cavity is formed inside the wheel cover 31;

[0049] An accommodating cavity is formed inside the wheel cover 31, and the accommodating cavity can be specifically defined by the edge of the opening side of the wheel cover 31, the side panel and the cover panel.

[0050] By arranging the arm valve assembly 4 in the accommodating cavity, the arm valve assembly 4 can be located in the area covered by the wheel cover 31, thereby preventing the arm valve assembly 4 from being damaged by falling rocks.

[0051] The arm valve assembly 4 is fixedly connected to the wheel cover 31 through the mounting assembly 500 .

[0052] The boom valve installation structure provided by the embodiment of the utility model, by setting the boom valve group in the accommodating cavity formed inside the wheel cover 31, and fixedly connecting it to the wheel cover 31 through the installation component 500, it is convenient to install the boom valve group 4 at a position closer to the boom 2, reduce the number of pipelines in the middle section of the whole vehicle, and reserve sufficient space in the middle section to facilitate the arrangement of other components, increase maintenance space, make the pipelines of the whole vehicle simpler and the appearance more beautiful; at the same time, due to the protection of the wheel cover 31, the safety of the boom valve group 4 can be improved to avoid the situation where the boom valve group 4 is damaged by falling rocks.

[0054] In some embodiments, in combination Figure 1 As shown, the boom valve assembly 4 is arranged in the wheel cover 31 on one side of the boom 2 along the vehicle length direction. By arranging the boom valve assembly 4 in the wheel cover 31 on one side of the boom 2 along the vehicle length direction, the boom valve assembly 4 can be closer to the boom 2, which is convenient for pipeline layout, while reducing the pipelines of the entire vehicle, providing more sufficient installation and maintenance space for other components.

[0055] In this embodiment, the arm 2 is located at the front end of the vehicle body 1 along the vehicle length direction. Correspondingly, the arm valve group 4 is arranged in the wheel cover 31 at the front end along the vehicle length direction.

[0056] In some embodiments, in combination Figure 2 , Figure 3As shown, the wheel cover 31 is provided with an operation clearance hole 311 , the operation clearance hole 311 is communicated with the accommodating cavity, and the operation clearance hole 311 is arranged opposite to the arm valve group 4 .

[0057] The operation clearance hole 311 is specifically provided on the side plate of the wheel cover 31 along the vehicle width direction. Thus, the wheel cover 31 can shield the top of the arm valve assembly 4 to prevent the arm valve assembly 4 from being damaged by falling rocks. At the same time, the wheel cover 31 can leave clearance space for the manual operating rod of the arm valve assembly 4, so that the operator can easily operate the manual operating rod of the arm valve assembly 4 through the operation clearance hole 311.

[0058] In some embodiments, in combination Figure 3 As shown, the first mounting portion 11 and the second mounting portion 12 are respectively provided on both sides of the tire 3, and the wheel cover 31 is provided with a first mounting frame 312 and a second mounting frame 314;

[0059] The first mounting bracket 312 is fixedly connected to the first mounting portion 11 via a first mounting member 313 , and the second mounting bracket 314 is fixedly connected to the second mounting portion 12 via a second mounting member 315 .

[0060] Among them, the first mounting part 11 and the second mounting part 12 can specifically be the front beam and the center beam of the vehicle body 1. A first mounting frame 312 is provided corresponding to the first mounting part 11 through the wheel cover 31, and a second mounting frame 314 is provided corresponding to the second mounting part 12 of the wheel cover 31, thereby facilitating the fixation of the wheel cover 31 and the vehicle body 1 and ensuring that the wheel cover 31 is firmly fixed.

[0061] In this embodiment, the wheel cover 31 can be made of metal material or hard plastic, so as to ensure the structural strength of the wheel cover 31.

[0062] In some embodiments, in combination Figure 5 As shown, the mounting assembly 500 includes: an internal mounting plate 5 of the wheel cover and an intermediate mounting frame 6, wherein the internal mounting plate 5 of the wheel cover is suitable for supporting the valve group mounting plate 7; the intermediate mounting frame 6 is fixedly connected to the inner wall of the wheel cover 31, and the intermediate mounting frame 6 is also formed with a supporting portion 61 suitable for being fixedly connected to the internal mounting plate 5 of the wheel cover.

[0063] The intermediate mounting frame 6 can be specifically welded and fixed to the mounting ribs 316 provided on the inner wall of the wheel cover 31. By providing a support portion 61 on the intermediate mounting frame 6, support can be provided to the mounting plate 5 inside the wheel cover, and the support portion 61 can be fixed to the mounting plate 5 inside the wheel cover through the mounting parts.

[0064] The mounting rib 316 can be welded to the wheel cover 31 . In the present embodiment, the mounting rib 316 is disposed at the lower edge of the wheel cover 31 , and the mounting rib 316 is constructed as an arc shape that matches the shape of the wheel cover 31 .

[0068] Since the arm valve group 4 is often composed of a plurality of valve structures which are independent of each other, if each valve structure included in the arm valve group 4 is fixed to the internal mounting plate 5 of the wheel cover respectively, it is easy to cause complicated operation and installation errors in the specific production process.

[0069] By installing the arm valve assembly 4 on the valve assembly mounting plate 7, it is convenient to uniformly assemble the multiple valve structures included in the arm valve assembly 4, so that the multiple valve structures form a unified whole. The pre-assembly of the arm valve assembly 4 is realized, and then the valve assembly mounting plate 7 is fixedly connected to the wheel cover internal mounting plate 5, which can improve the assembly efficiency and avoid missing the valve structure.

[0070] In this embodiment, the arm valve group 4 is installed on the valve group mounting plate 7 by means of mounting parts such as screws, spring washers, and flat washers.

[0071] In some embodiments, in combination Figure 5 As shown, the valve assembly mounting plate 7 is fixedly connected to the wheel cover inner mounting plate 5 via a fourth mounting member 71. Specifically, the valve assembly mounting plate 7 is mounted on the wheel cover inner mounting plate 5 by mounting members such as screws, spring washers, and flat washers.

[0072] In some embodiments, in combination Figure 5 As shown, the wheel cover 31 is constructed in an arc shape; the area where the mounting plate 5 inside the wheel cover supports the valve assembly mounting plate 7 forms a straight section 52, and the straight section 52 is constructed in a straight plate shape and is located relatively above the tire 3;

[0073] The wheel housing inner mounting plate 5 also forms a fixing section 53 abutting against the supporting portion 61 , and an extending section 51 is connected between the fixing section 53 and the straight section 52 .

[0074] In this embodiment, the straight section 52 is constructed in a straight plate shape, and the plane where the straight section 52 is located is preferably parallel to the horizontal plane, or the plane where the straight section 52 is located is set at an acute angle to the horizontal plane.

[0075] By forming a straight section 52 on the mounting plate 5 inside the wheel cover, the valve group mounting plate 7 can be easily installed and positioned, thereby improving the supporting effect of the valve group mounting plate 7 and preventing the valve group mounting plate 7 from slipping.

[0076] Furthermore, the wheel cover internal mounting plate 5 also forms a fixed section 53 abutting against the support portion 61, and an extension section 51 is connected between the fixed section 53 and the straight section 52, so that the wheel cover internal mounting plate 5 is constructed in a trapezoidal shape, which facilitates the arrangement of the wheel cover internal mounting plate 5 relatively above the wheel cover 31 constructed in an arc shape.

[0077] The inner mounting plate 5 of the wheel cover is provided with fixing sections 53 on both sides along the vehicle length direction. Correspondingly, the middle mounting frame 6 is provided on both sides along the vehicle length direction of the wheel cover 31, so as to facilitate the middle mounting frame 6 to support and fix both sides of the inner mounting plate 5 of the wheel cover.

[0078] In some embodiments, in combination Figure 5 As shown, the fixing section 53 is fixedly connected to the support portion 61 via a third mounting member 54. Specifically, the fixing section 53 is mounted on the support portion 61 via mounting members such as screws, spring washers, and flat washers.

[0079] According to an embodiment of the present utility model, on the other hand, there is also provided an engineering vehicle, comprising:

[0080] The vehicle body 1 and the boom 2, and the boom valve mounting structure as described above.

[0081] In some embodiments, the boom valve assembly 4 is arranged in the wheel cover 31 close to the side of the boom 2 along the vehicle length direction. By arranging the boom valve assembly 4 in the wheel cover 31 and fixing it with the wheel cover 31 through the mounting assembly 500, it is convenient to install the boom valve assembly 4 at a position closer to the boom 2, reduce the number of pipelines in the middle section of the vehicle, and reserve sufficient space in the middle section, which is convenient for arranging other components, increase maintenance space, make the pipelines of the vehicle simpler, and make the appearance more beautiful; at the same time, due to the protection of the wheel cover 31, the safety of the boom valve assembly 4 can be improved, and the situation of the boom valve assembly 4 being damaged by falling rocks can be avoided.
