Description
Technical Field
[0001] The utility model relates to the technical field of engineering machinery, in particular to a post-processing heat insulation device and engineering machinery. Background Art
[0002] Engineering machinery and equipment are usually equipped with high-power engines due to the particularity of their application scenarios, and their supporting engine post-processing is also relatively large and complex. At the same time, due to the restrictions on the length, width, height and other parameters of engineering machinery and equipment by relevant laws and regulations, the installation space reserved for the power system of the equipment is usually very compact, and the engine and its post-processing are usually arranged in the gap. For example, in the power system of a crane, the post-processing is usually arranged on the top of the shed, and air filters, expansion tanks, hydraulic pipes, electrical wiring harnesses and other components are arranged in the front, back, left and right.
[0003] Due to the high temperature of the engine aftertreatment, for the reliability of the aftertreatment and the safety of the whole vehicle, a heat insulation device needs to be designed on the outside of the aftertreatment. At present, the aftertreatment heat insulation device of the power system of engineering machinery is mostly designed as a semi-enclosed structure made of 2.0-3.0mm aluminum alloy plates bent and welded, and multiple heat dissipation holes are designed on the aluminum alloy plates. Utility Model Content
[0004] However, the inventor of the present application has found that this type of semi-enclosed aluminum alloy plate heat shield with multiple heat dissipation holes currently has multiple disadvantages. First, because the post-processing heat cannot be dissipated in time, the temperature inside the heat shield is high, which can easily cause the post-processing sensors, electrical wiring harnesses, urea pipes, cooling water pipes and other components inside the heat shield to deform and fail due to high temperature; secondly, because the heat dissipation apertures on the heat shield are relatively large, some flammable materials (such as leaves, etc.) can easily enter the heat shield by mistake during outdoor operation of the equipment, and catch fire and burn due to high temperature baking, threatening the safety of the equipment; in addition, due to the large post-processing volume, the heat shield needs to consume a large amount of aluminum alloy plate materials, and at the same time, there are many bending edges, a large amount of heat dissipation holes are punched, and the number of welds is large and long. The complex production process directly leads to the high cost of this type of semi-enclosed aluminum alloy plate heat shield.
[0005] In view of this, the utility model provides an engineering machine to solve the above problems.
[0006] In the first aspect, the utility model provides a leg plate, which is arranged on the outside of a post-processing device, comprising: a bracket, which includes a plurality of connected support members, and the plurality of support members together form a receiving space; and at least one wire mesh member, which is connected to the corresponding support member and covers a portion of the receiving space, and the wire mesh member is in the shape of a porous mesh.
[0007] In an optional embodiment, a plurality of the support members are connected to form a polygonal body, at least one surface of which is covered by the wire mesh member.
[0008] In an optional embodiment, the shape of the wire mesh member is adapted to a surface surrounded by a plurality of the support members, and each edge of the wire mesh member is connected to a corresponding support member.
[0009] In an optional embodiment, the wire mesh member is welded to the support member.
[0010] In an optional embodiment, it further includes an inspection cover plate, an inspection opening is opened on one of the wire mesh parts, and the inspection cover plate is covered on the inspection opening.
[0011] In an optional embodiment, a avoidance opening is opened on one of the wire mesh parts, and a reinforcement piece is arranged at the edge of the avoidance opening.
[0012] In an optional embodiment, the support member is an angle steel, and a plurality of fasteners are provided on the support member for mounting to the upper vehicle.
[0013] In an optional embodiment, the fastener is a pre-embedded welding nut.
[0014] In an optional embodiment, each of the wire mesh members is spaced a preset distance from the post-processing device.
[0015] In a second aspect, the utility model also provides an engineering machinery, comprising the above-mentioned post-processing heat insulation device.
[0016] According to the utility model, the heat generated by the post-processing device can be effectively dissipated, thereby preventing the internal temperature of the post-processing heat insulation device from being too high, protecting the post-processing sensors, electrical wiring harnesses, urea pipes, cooling water pipes and other components inside the post-processing heat insulation cover from overheating and failure; on the other hand, it prevents the peripheral temperature of the post-processing device from being too high, causing the surrounding components to deform, melt and fail due to heat; on the other hand, it can also prevent flammable materials (such as leaves, etc.) from accidentally entering the interior of the post-processing heat insulation device during outdoor operation of the equipment, catching fire and burning due to high temperature baking, threatening the safety of the equipment. In addition, since the post-processing device on the construction machinery is generally large in size, the use of the wire mesh parts of this embodiment does not require a large amount of aluminum alloy plates, does not require bending of aluminum alloy plates, and does not require a large number of processes for stamping heat dissipation holes, which can effectively reduce costs.

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0029] Combine the following Figure 1 to Figure 2 , describing an embodiment of the utility model.
[0030] According to an embodiment of the utility model, on the one hand, a post-processing heat insulation device 100 is provided, which includes a bracket 10 and at least one wire mesh member 20. The bracket includes a plurality of connected support members 11, and the plurality of support members 11 together form a receiving space for receiving the post-processing device 200 on the vehicle. The wire mesh member 20 is in the shape of a porous mesh. The wire mesh member 20 is connected to the corresponding support member 11 and covers part of the receiving space.
[0031] The post-processing heat insulation device 100 of this embodiment is applied, and a receiving space is formed by the bracket 10 to receive the post-processing device 200, and a porous mesh wire mesh 20 connected to the bracket 10 is used to cover the receiving space, that is, the bracket 10 is used as the skeleton, and the wire mesh 20 is used as the surrounding surface. On the one hand, the heat generated by the post-processing device 200 can be effectively dissipated, thereby preventing the internal temperature of the post-processing heat insulation device 100 from being too high, and protecting the post-processing sensors, electrical wiring harnesses, urea pipes, cooling water pipes and other components inside the post-processing heat insulation cover from overheating and failure; on the other hand, it prevents the peripheral temperature of the post-processing device 200 from being too high, causing the surrounding components to deform, melt, and fail due to heat; on the other hand, it can also prevent flammable objects (such as leaves, etc.) from easily entering the interior of the post-processing heat insulation device 100 during outdoor operation of the equipment, and catching fire and burning due to high temperature, threatening the safety of the equipment. In addition, since the post-processing device 200 on the construction machinery generally has a large volume, compared with the current semi-enclosed aluminum alloy plate heat insulation cover with multiple heat dissipation holes, the wire mesh part 20 of this embodiment does not require a large number of aluminum alloy plates, does not require bending of the aluminum alloy plates, and does not require a large number of stamping heat dissipation holes, which can effectively reduce costs.
[0032] like Figure 1 and Figure 2 As shown, the bracket 10 is a polygonal body, and is covered on the outside of the post-processing device 200 on the vehicle. Specifically, in this embodiment, the bracket 10 is a rectangular parallelepiped, including twelve support members 11, that is, the twelve support members 11 are the edges of the rectangular parallelepiped. The support members 11 are generally strip-shaped, and in this embodiment, the support members 11 are angle steels. Specifically, a plurality of fasteners 12 are provided on the support members 11 for mounting on the vehicle, and the fasteners are pre-embedded welding nuts, which facilitate the installation of the post-processing heat insulation device 100 on the vehicle.
[0033] It can be understood that the bracket 10 is not limited to a rectangular shape. The shape, size and installation position of the bracket 10 can be adaptively modified according to the size of the post-processing device 200 and the positions of other components on the vehicle, such as the air filter, expansion tank, hydraulic pipeline, electrical wiring harness, etc., as long as there is no interference with other components, and preferably the interval between the bracket 10 and the post-processing device 200 is greater than a preset distance, for example 50 mm.
[0034] In this embodiment, the post-processing heat insulation device 100 includes five wire mesh members 20. Figure 1 and Figure 2As shown, the wire mesh member 20 is in the shape of a porous mesh and is made of metal. The shape of the wire mesh member 20 is adapted to a surface surrounded by a plurality of the support members 11. Specifically, in the present embodiment, the wire mesh member 20 is in a rectangular shape. Furthermore, five wire mesh members 20 are respectively connected to corresponding support members 11. In other words, one surface of the bracket 10 is not covered by the wire mesh member 20, and is used for being installed to the outside of the post-processing device 200. Furthermore, each edge of each wire mesh member 20 is connected to a corresponding support member 11. Specifically, the wire mesh member 20 is welded to the support member 11. It can be understood that the wire mesh member 20 and the support member 11 can also be connected in other ways, as long as the reliability of the connection is guaranteed.
[0035] Preferably, the aperture of the wire mesh 20 is selected to be 10-15 mm, which effectively prevents external components of the post-processing insulation device 100 and other flammable materials from entering the insulation cover, thereby avoiding safety hazards such as fire and combustion caused by flammable materials contacting the surface of the post-processing device 200.
[0036] Those skilled in the art can understand that the heat dissipation effect of the wire mesh part 20 is better than that of the aluminum alloy plate with punched holes. At the same time, the wire mesh part 20 is less likely to burn workers due to excessive temperature than the aluminum alloy plate.
[0037] It can be understood that the number of the wire mesh pieces 20 is not limited to five and can be set according to actual needs.
[0038] like Figure 2 As shown, the post-processing heat insulation device 100 further includes an inspection cover plate 30. An inspection opening is provided on a wire mesh member 20, and the inspection cover plate 30 is covered on the inspection opening. In this embodiment, the inspection opening is rectangular, and the inspection cover plate 30 is adaptively rectangular.
[0039] It can be understood that the inspection port is provided to facilitate maintenance of the post-processing device 200 , and therefore its position and size are suitable for facilitating personnel to repair various sensors and pipelines of the post-processing device 200 .
[0040] Preferably, the post-processing heat insulation device 100 further comprises a mounting plate 50. The mounting plate 50 is in a square frame shape and is adapted to the shape and size of the inspection opening. The mounting plate 50 is welded to the wire mesh member 20. The inspection cover plate 30 is connected to the mounting plate 50 by bolts to cover the inspection opening.
[0041] Further, a mesh member 20 is provided with an escape opening for evacuating the exhaust pipe of the post-processing device 200. A reinforcing member 40 is provided at the edge of the escape opening to prevent the strength of the mesh member 20 from being reduced too much, and to be aesthetically pleasing, while preventing people from being cut by the mesh member 20.
[0042] According to an embodiment of the present invention, on the other hand, a construction machine is provided, comprising: the above-mentioned post-processing heat insulation device 100 and the post-processing device 200.
[0043] Furthermore, the construction machinery includes but is not limited to excavators, cranes, pile drivers, mixers, etc.
[0044] In the related technology, the post-processing heat cannot be dissipated in time, and the temperature inside the heat insulation cover is high, which can easily cause the post-processing sensors, electrical wiring harnesses, urea pipes, cooling water pipes and other components inside the heat insulation cover to deform and fail due to high temperature; secondly, because the heat dissipation apertures on the heat insulation cover are relatively large, certain flammable materials (such as leaves, etc.) can easily enter the heat insulation cover by mistake during outdoor operation of the equipment, and catch fire and burn due to high temperature, threatening the safety of the equipment; in addition, due to the large volume of the post-processing, the heat insulation cover requires a large amount of aluminum alloy plate material, and at the same time, there are many bending edges, a large amount of heat dissipation holes punched, and a large number of long welds. The complex production process directly leads to the high cost of this semi-enclosed structure aluminum alloy plate heat insulation cover.
[0045] In this embodiment, the heat generated by the post-processing device 200 can be effectively dissipated, thereby preventing the internal temperature of the post-processing heat insulation device 100 from being too high, protecting the post-processing sensors, electrical wiring harnesses, urea pipes, cooling water pipes and other components inside the post-processing heat insulation cover from overheating and failure; on the other hand, it prevents the peripheral temperature of the post-processing device 200 from being too high, causing the surrounding components to deform, melt and fail due to heat; on the other hand, it can also prevent flammable materials (such as leaves, etc.) from accidentally entering the interior of the post-processing heat insulation device 100 during the outdoor operation of the equipment, catching fire and burning due to high temperature baking, threatening the safety of the equipment. In addition, since the post-processing device 200 on the construction machinery is generally large in size, the use of the wire mesh part 20 of this embodiment does not require a large amount of aluminum alloy plates, does not require bending of aluminum alloy plates, and does not require a large number of processes for stamping heat dissipation holes, which can effectively reduce costs.
[0046] Although the embodiments of the present invention are described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
