Description

Technical Field

[0001] The present invention relates to the technical field of operating machinery, and in particular to a rainproof exhaust tail pipe and an operating machinery. Background Art

[0002] Various application scenarios need to be considered when using operating machinery. For example, on rainy days, in order to prevent rainwater from entering the engine through the engine exhaust pipe, the end of the exhaust pipe needs to have rainproof properties to ensure that the operating machinery can work reliably on rainy days.

[0003] In order to improve the rainproof ability of the exhaust pipe, a bend device is usually installed on the exhaust pipe and a drainage plate is set to drain the rainwater entering the bend, thereby protecting the exhaust pipe and the exhaust gas treatment equipment from the influence of rainwater. The size of the bend in the prior art is relatively long and high, which is not suitable for some situations where the height and width of the engine exhaust tail pipe are restricted. For example, for rotary drilling rigs, with the upgrade of engine emission regulations, the volume of the exhaust gas after-treatment device has increased, which has restricted the height of the exhaust tail pipe; in addition, in order to meet the width requirements of non-road machinery transportation, the size of the bend of the exhaust tail pipe should not be too long.

[0004] Therefore, how to design and arrange an exhaust tail pipe with low resistance and high waterproof performance while taking into account the height and width size restrictions is a technical problem that needs to be solved. Summary of the invention

[0005] The present invention provides a rainproof exhaust tail pipe and an operating machine, which are used to solve the defect in the prior art that the exhaust tail pipe is difficult to exert rainproof performance and exhaust performance when the size is limited, and to achieve the exhaust performance and improve the rainproof performance of the exhaust tail pipe when the size of the exhaust tail pipe is limited.

[0006] The present invention provides a rainproof exhaust tail pipe, comprising: a tail pipe fitting, wherein the tail pipe fitting comprises a vertical pipe section and a curved pipe section, wherein the vertical pipe section is installed on the exhaust pipe of an operating machine, wherein the inner diameter of the vertical pipe section is larger than the outer diameter of the exhaust pipe of the operating machine, and a drainage gap is formed between the inner surface of the vertical pipe section and the outer surface of the exhaust pipe of the operating machine; a sleeve fitting, wherein the sleeve fitting is arranged at the opening of the curved pipe section, wherein the inner diameter of the sleeve fitting is larger than the outer diameter of the curved pipe section, and at least a portion of the curved pipe section is located in the sleeve fitting; and a flow guide, wherein the flow guide is arranged at the outlet of the sleeve fitting, and at least a portion of the flow guide is located on the inner side of the outlet of the sleeve fitting.

[0007] According to a rainproof exhaust tail pipe provided by the present invention, the opening direction of the curved pipe section is parallel to the horizontal direction; or the opening direction of the curved pipe section is inclined upward relative to the horizontal direction. Specifically, this embodiment provides an implementation method of the angle relationship between the opening direction of the curved pipe section and the horizontal direction. In the case where the sleeve member blocks the opening of the curved pipe section, the opening direction of the curved pipe section is set to be parallel to or inclined upward relative to the horizontal direction, thereby greatly reducing the amount of rainwater entering the curved pipe section.

[0008] According to a rainproof exhaust tail pipe provided by the present invention, the opening end face of the curved pipe section is inclined relative to the vertical direction, and the upper edge of the opening is longer than the lower edge in the horizontal direction; and / or the outlet end face of the sleeve member is inclined relative to the vertical direction, and the upper edge of the outlet is longer than the lower edge in the horizontal direction. Specifically, this embodiment provides an implementation method in which the opening end face of the curved pipe section and / or the outlet end face of the sleeve member are inclined. By making the upper edge of the curved pipe section opening and / or the sleeve member outlet longer than the lower edge in the horizontal direction, it is difficult for vertically falling rainwater to fall into the opening and / or outlet.

[0009] According to the present invention, a rainproof exhaust tail pipe further includes: a bracket, the bracket is respectively fixed to the outer surface of the tail pipe member and the outer surface of the sleeve member; the end of the curved pipe section of the tail pipe member is suspended and extends into the sleeve member. Specifically, this embodiment provides an implementation method of arranging a bracket between the tail pipe member and the sleeve member. The bracket is used to fix the outer surface of the tail pipe member and the outer surface of the sleeve member, so that the tail pipe member and the sleeve member can be fixed in relative position without direct contact, and the end of the curved pipe section can be suspended and extended into the sleeve member.

[0010] According to a rainproof exhaust tail pipe provided by the present invention, the bracket includes a first connecting plate and a second connecting plate fixed to each other; the first connecting plate is arranged on the tail pipe member, and the second connecting plate is arranged on the sleeve member. Specifically, this embodiment provides an implementation method in which the bracket includes a first connecting plate and a second connecting plate. The first connecting plate and the second connecting plate are respectively fixed to the outer surfaces of the tail pipe member and the sleeve member.

[0011] According to a rainproof exhaust tail pipe provided by the present invention, the angle between the plate surfaces of the first connecting plate and the second connecting plate is an acute angle, a right angle or an obtuse angle; the connection between the first connecting plate and the second connecting plate is fixedly provided with a reinforcing rib structure respectively connected to the plate surfaces of the first connecting plate and the second connecting plate. Specifically, this embodiment provides an angular relationship between the first connecting plate and the second connecting plate, and an implementation method of providing a reinforcing rib structure. Among them, according to the respective installation positions of the first connecting plate and the second connecting plate, the angle between the plate surfaces of the two can be an acute angle, a right angle or an obtuse angle; and the reinforcing rib structure can increase the structural strength of the connection between the first connecting plate and the second connecting plate, thereby improving the support reliability of the bracket.

[0012] According to a rainproof exhaust tail pipe provided by the present invention, the guide member is a conical cover, the maximum diameter of the conical cover is smaller than the inner diameter of the sleeve member, and the wide-angle side of the conical cover faces the outer side of the sleeve member outlet.

[0013] According to a rainproof exhaust tail pipe provided by the present invention, a support plate is provided between the conical cover and the sleeve member; one end of the support plate is connected to the outer conical surface of the conical cover, and the other end is connected to the inner surface of the sleeve member. Specifically, this embodiment provides an implementation method in which a support plate is provided between the conical cover and the sleeve member. The support plate enables the installation of the conical cover in the sleeve member, and enables the conical cover to maintain a spacing from the sleeve member in all directions, thereby improving the ventilation performance of the sleeve member.

[0014] According to a rainproof exhaust tail pipe provided by the present invention, there are multiple support plates, and the multiple support plates are evenly distributed around the circumference of the conical cover. Specifically, this embodiment provides an implementation method in which there are multiple support plates. The multiple support plates are connected between the conical cover and the sleeve member at different positions, thereby improving the support structure strength of the conical cover.

[0015] According to a rainproof exhaust tail pipe provided by the present invention, the center line of the conical cover coincides with the center line of the sleeve; or, the center line of the conical cover is parallel to and deviates from the center line of the sleeve; or, the angle between the center line of the conical cover and the center line of the sleeve is an acute angle. Specifically, this embodiment provides an implementation method of different relative position relationships between the conical cover and the sleeve.

[0016] The present invention also provides an operating machine, comprising the rainproof exhaust tail pipe described in any one of the above embodiments.

[0017] The rainproof exhaust tail pipe provided by the present invention is arranged in the sleeve member through a part of the curved pipe section of the tail pipe member, so that the sleeve member forms a radial shielding at the exhaust outlet of the tail pipe member. Among them, a drainage gap is formed between the vertical pipe section and the outer surface of the exhaust pipe, and the rainwater entering the tail pipe member is discharged through the drainage gap to prevent the rainwater from entering the exhaust pipe; the inner diameter of the sleeve member is larger than the outer diameter of the curved pipe section to prevent the rainwater from flowing into the tail pipe member along the inner wall of the sleeve member. The guide member is arranged at the outlet of the sleeve member, and a partial shielding is formed at the outlet of the sleeve member. In the process of rainwater falling to the outlet of the sleeve member, the outlet of the sleeve member reduces the opening size in the direction of rainwater falling under the shielding of the guide member, so that part of the rainwater can be blocked by the guide member, reducing the possibility of rainwater falling directly into the sleeve member. The guide member plays an exhaust diversion role in the exhaust process, and has little effect on the exhaust efficiency. The rainproof exhaust tail pipe of the present invention can improve the rainproof performance of the exhaust tail pipe while meeting the exhaust performance. The operating machinery adopting the rainproof exhaust tail pipe can meet the exhaust requirements of low resistance and high waterproof performance. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. 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.

[0026] In the description of the embodiments of the present invention, it should be noted that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, rather than indicating or implying that the devices or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limitations on the embodiments of the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. It should also be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "set", "install", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0027] With the upgrade of engine emission regulations for operating machinery and increasingly stringent transportation size regulations, the volume of devices such as the after-treatment assembly has increased, and the newly added carrier and nitrogen oxide sensor have waterproof requirements. In actual projects, there are situations where construction is carried out on rainy days, and the design of the exhaust tail pipe outlet has put forward higher requirements. The design and layout of the exhaust tail pipe needs to take into account low resistance, waterproof function, and height and width size restrictions.

[0028] In order to improve the rainproof performance of the exhaust tail pipe while satisfying the exhaust performance, the present invention provides a rainproof exhaust tail pipe for an operating machine, wherein the operating machine may be a rotary drilling rig, a crane, a mixer, an excavator, etc.

[0029] Combine the following Figure 1-Figure 4 The specific implementation of the rainproof exhaust tail pipe of the present invention is described. Figure 1 and Figure 2 They are schematic side views of the rainproof exhaust tail pipe from different sides. Figure 3 This is a top view of the rainproof exhaust tail pipe. Figure 4 It is a schematic diagram of the cross-sectional structure of the rainproof exhaust tail pipe.

[0030] According to the present invention, a rainproof exhaust tail pipe includes: a tail pipe member 10, the tail pipe member 10 includes a vertical pipe section 11 and a curved pipe section 12, the vertical pipe section 11 is installed on the exhaust pipe of the working machine, the inner diameter of the vertical pipe section 11 is larger than the outer diameter of the exhaust pipe of the working machine; a drainage gap 13 is formed between the inner surface of the vertical pipe section 11 and the outer surface of the exhaust pipe of the working machine. A sleeve member 20, the sleeve member 20 is arranged at the opening of the curved pipe section 12, the inner diameter of the sleeve member 20 is larger than the outer diameter of the curved pipe section 12, and at least a part of the curved pipe section 12 is located in the sleeve member 20; a flow guide, the flow guide is arranged at the outlet of the sleeve member 20, and at least a part of the flow guide is located inside the outlet of the sleeve member 20.

[0031] like Figure 1 and Figure 4 As shown, the above-mentioned rainproof exhaust tail pipe is arranged in the sleeve member 20 through a part of the curved pipe section 12 of the tail pipe member 10, so that the sleeve member 20 forms a radial obstruction at the exhaust outlet of the tail pipe member 10. Among them, the inner diameter of the sleeve member 20 is larger than the outer diameter of the curved pipe section 12, which can prevent rainwater from flowing into the tail pipe member 10. The guide member is arranged at the outlet of the sleeve member 20, and the guide member can block the rainwater before the rainwater enters the outlet of the sleeve member 20. In the exhaust process, the guide member plays a guiding role and has little effect on the exhaust efficiency. The rainproof exhaust tail pipe of the present invention can improve the rainproof performance of the exhaust tail pipe while meeting the exhaust performance.

[0032] like Figure 4 As shown, the rectangle at the bottom of the figure is used to represent the exhaust pipe of the operating machinery. Through the above-mentioned drainage gap 13, rainwater entering the tail pipe 10 can flow downward along the inner wall of the tail pipe 10 until it is discharged through the drainage gap 13, thereby preventing rainwater from entering the exhaust pipe.

[0033] There may be no connection between the vertical pipe section 11 and the exhaust pipe of the operating machine, and the vertical pipe section 11 is installed on the support structure of other equipment and sleeved on the exhaust pipe to achieve the structure with the drainage gap 13. Preferably, the vertical pipe section 11 and the exhaust pipe of the operating machine can also be connected through a mesh plate or a support structure, and the drainage gap 13 can be a hole structure of the mesh plate, or a structural gap of the support structure.

[0034] In practical applications, the vertical pipe section 11 of the tail pipe 10 is arranged along or close to the vertical direction (gravity direction), and the curved pipe section 12 is bent from the top of the vertical pipe section 11 to the rear of the equipment. Figure 3 As shown in FIG. 1 , rain usually falls directly on the top of the sleeve member 20 and the tail pipe member 10, and slides down along the outer surfaces of the sleeve member 20 and the tail pipe member 10. When the wind blows the falling path of the rain off, the rain falls into the sleeve member 20, as shown in FIG. Figure 4As shown, the guide member arranged at the outlet of the sleeve member 20 forms a barrier for rainwater.

[0035] The guide member can be in various forms, such as a guide plate inclined relative to the horizontal plane, an arc-shaped plate, or a plurality of guide blades arranged in parallel. Since the diameter of the sleeve member 20 is larger than the curved pipe section 12 of the tail pipe member 10, even if a small amount of rainwater enters the sleeve member 20, it can flow out from the gap between the sleeve member 20 and the curved pipe section 12. Similarly, even if a small amount of rainwater enters the tail pipe member 10, such as Figure 4 As shown by the black arrow in FIG. 1 , rainwater can be discharged from the drainage gap 13 along the inner wall of the tail pipe 10 .

[0036] According to the present invention, a rainproof exhaust tail pipe is provided, such as Figure 1 and Figure 4 As shown, the opening direction of the curved pipe section 12 is parallel to the horizontal direction; or the opening direction of the curved pipe section 12 is inclined upward relative to the horizontal direction.

[0037] In the case where the sleeve 20 blocks the opening of the elbow pipe section 12, setting the opening direction of the elbow pipe section 12 to be parallel or inclined upward to the horizontal direction can prevent rainwater falling on the surface of the elbow pipe section 12 from flowing to the opening of the elbow pipe section 12, and can also reduce the space requirement of the exhaust tail pipe in the height direction. Moreover, the opening direction of the elbow pipe section 12 is inclined upward relative to the horizontal direction, which is conducive to the rainwater entering the elbow pipe section 12 flowing to the drainage gap 13 under the action of gravity, preventing water from accumulating in the elbow pipe section 12.

[0038] According to the present invention, a rainproof exhaust tail pipe is provided, such as Figure 4 As shown, the opening end face of the curved pipe section 12 is inclined relative to the vertical direction, and the upper edge of the opening is longer than the lower edge in the horizontal direction; and / or the outlet end face of the sleeve member 20 is inclined relative to the vertical direction, and the upper edge of the outlet is longer than the lower edge in the horizontal direction. The upper edge of the opening of the curved pipe section 12 and / or the outlet of the sleeve member 20 is longer than the lower edge in the horizontal direction, so that rainwater falling vertically is difficult to fall into the opening and / or the outlet. Moreover, the inclined opening of the end face can also increase the opening area of ​​the curved pipe section 12 and / or the outlet area of ​​the sleeve member 20, thereby improving the exhaust performance of the exhaust tail pipe.

[0039] The top of the elbow section 12 can be installed and connected with the sleeve member 20 by welding, bonding, bolting, etc., so as to mainly retain the structural gap between the bottom of the elbow section 12 and the sleeve member 20. In addition, the sleeve member 20 can also be fixed to the outlet end of the elbow section 12 by other bracket structures.

[0040] According to the present invention, a rainproof exhaust tail pipe is provided, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, it is preferred to further include a bracket 21; the bracket 21 is fixed to the outer surface of the tail pipe member 10 and the outer surface of the casing member 20 respectively; the end of the curved pipe section 12 of the tail pipe member 10 is suspended and extends into the casing member 20. The bracket 21 is used to fix the outer surface of the tail pipe member 10 and the outer surface of the casing member 20, so that Figure 2 As shown, the tail pipe member 10 and the sleeve member 20 can be fixed in relative position without direct contact, so that the end of the elbow section 12 can be suspended and extended into the sleeve member 20, and a gap is reserved around the end of the elbow section 12. The bracket 21 can be connected to the outer surface of the tail pipe member 10 and the outer surface of the sleeve member 20 by a fixed method such as welding, or can be detachably connected by a clamp, a slot, etc., so as to facilitate local maintenance of the workpiece.

[0041] According to the present invention, a rainproof exhaust tail pipe is provided, such as Figure 1 and Figure 4 As shown, the bracket 21 preferably includes a first connecting plate 22 and a second connecting plate 23 fixed to each other; the first connecting plate 22 is arranged on the tail pipe member 10, and the second connecting plate 23 is arranged on the sleeve member 20. The first connecting plate 22 and the second connecting plate 23 are respectively fixed to the outer surfaces of the tail pipe member 10 and the sleeve member 20, so that the first connecting plate 22 and the second connecting plate 23 form a support for the sleeve member 20.

[0042] According to a rainproof exhaust tail pipe provided by the present invention, the plate surface angle between the first connecting plate 22 and the second connecting plate 23 can be an acute angle, a right angle or an obtuse angle. At the connection between the first connecting plate 22 and the second connecting plate 23, a reinforcing rib structure 24 connected to the plate surfaces of the first connecting plate 22 and the second connecting plate 23 is preferably fixedly provided. Among them, according to the different installation positions of the first connecting plate 22 and the second connecting plate 23, the angle between the plate surfaces of the two is different, which can be an acute angle, a right angle or an obtuse angle. The reinforcing rib structure 24 can increase the structural strength of the connection between the first connecting plate 22 and the second connecting plate 23, and improve the support reliability of the bracket 21.

[0043] The reinforcing rib structure 24 may be a plate-like structure, the plate surface of which is perpendicular to the first connecting plate 22 and the second connecting plate 23 respectively; the reinforcing rib structure 24 may also be a connecting rod, which connects the first connecting plate 22 and the second connecting plate 23 to form a triangular supporting structure.

[0044] The guide member of each of the above embodiments may have various forms. According to a preferred embodiment of the present invention, the guide member is preferably as follows: Figure 1 , Figure 2 and Figure 4The conical cover 30 shown in the figure. The maximum diameter of the conical cover 30 is smaller than the inner diameter of the sleeve 20, and the wide-angle side of the conical cover 30 faces the outer side of the outlet of the sleeve 20. When the equipment is in operation, the exhaust gas flow in the pipeline is discharged out of the sleeve 20 at a wide angle along the outer conical surface of the conical cover 30, and rainwater can be prevented from entering the sleeve 20 through the gap around the conical cover 30.

[0045] According to the rainproof exhaust tail pipe provided by the present invention, a part of the conical cover 30 can be fixedly connected to the sleeve member 20. Figure 2 and Figure 4 As shown, a support plate 31 is provided between the conical cover 30 and the sleeve member 20; one end of the support plate 31 is connected to the outer cone surface of the conical cover 30, and the other end is connected to the inner surface of the sleeve member 20. The support plate 31 enables the installation of the conical cover 30 in the sleeve member 20, and enables the conical cover 30 to maintain a gap with the sleeve member 20 in all directions, thereby improving the ventilation performance of the sleeve member 20.

[0046] When the exhaust gas reaches the conical cover 30, it is guided by the outer cone surface of the conical cover 30 to the space between the conical cover 30 and the outlet edge of the sleeve member 20, which has little blocking effect on the exhaust gas and can play a role in guiding the airflow around the conical cover 30, preventing rainwater from falling into the gap between the conical cover 30 and the sleeve member 20.

[0047] According to the conical cover 30 of the rainproof exhaust tail pipe, it can play an important role in the exhaust system of the rotary drilling rig. The taper range of the conical cover 30 is preferably 30° to 120°, and the projected area in the horizontal direction accounts for 15% to 35% of the projected area of ​​the casing member 20, and it will not protrude from the outermost edge of the casing member 20. The above scheme allows the conical cover 30 to provide sufficient exhaust area while avoiding excessive resistance. When the exhaust reaches the conical cover 30, its outer cone design can guide the airflow to flow between the conical cover 30 and the outlet edge of the casing member 20, which not only reduces the blocking effect on the exhaust, but also plays the role of airflow injection around the conical cover 30. In addition, the conical cover 30 is preferably arranged on the center line of the casing member 20, and can also be eccentrically arranged when the above characteristics are met. The design of the conical cover 30 makes the exhaust gas discharge resistance smaller, and the exhaust gas can be discharged smoothly when the rotary drilling rig is in normal construction state, thereby ensuring the normal operation of the equipment and construction efficiency.

[0048] According to the rainproof exhaust tail pipe provided by the present invention, there can be multiple support plates 31, and the multiple support plates 31 are evenly distributed around the circumference of the conical cover 30. The multiple support plates 31 are connected between the conical cover 30 and the sleeve 20 at different positions, thereby improving the support structure strength of the conical cover 30. Figure 2As shown, in a preferred embodiment of the present invention, three support plates 31 are provided to form a relatively stable three-point support structure for the cone cover 30 .

[0049] According to a rainproof exhaust tail pipe provided by the present invention, the center line of the conical cover 30 preferably coincides with the center line of the sleeve 20. It is understandable that, according to the actual application scenario, the position and posture of the conical cover 30 are preferably adjustable to adapt to various working conditions. For example, the center line of the conical cover 30 can be parallel to and deviate from the center line of the sleeve 20; or, the center line of the conical cover 30 can be at an acute angle to the center line of the sleeve 20.

[0050] The present invention further provides a working machine, comprising the rainproof exhaust tail pipe of any one of the above embodiments. In the embodiments of the present invention, the type of the working machine is not limited, for example, the working machine may be a rotary drilling rig, a crane, an excavator, etc.
