Description

Technical Field

[0001] This utility model relates to the field of diesel vehicle production exhaust gas treatment technology, and in particular to a folding swing arm exhaust gas extraction device. Background Technology

[0002] In the production of diesel vehicles such as construction machinery and trucks, a large amount of exhaust gas is emitted when the engine starts. This exhaust gas not only contains harmful gases but may also carry pollutants such as oil mist and particulate matter, posing a threat to the production environment and the health of operators. Therefore, effective exhaust gas extraction equipment is an important tool to ensure a clean production environment and protect worker health.

[0003] Traditional exhaust gas extraction equipment mostly adopts a single-arm structure, collecting exhaust gases through fixed or limited-angle adjustable pipes. However, this single-arm structure has obvious limitations: First, the coverage area is limited, making it difficult to adapt to exhaust gas sources at different locations and angles; second, it lacks flexibility, often requiring the entire equipment to be moved or the pipes to be rearranged when the extraction position needs to be adjusted, which is cumbersome and inefficient; third, it occupies a large space, as the single-arm structure often cannot be effectively folded or stored when not in use, occupying valuable production space. In addition, the pipe connections of traditional exhaust gas extraction equipment mostly use rigid connections, lacking the necessary extensibility and flexibility, making it difficult to adapt to changes in the position of the exhaust gas outlet during engine startup, which may lead to poor exhaust gas collection or even exhaust gas leakage.

[0004] Therefore, a folding swing arm exhaust gas extraction device is proposed. Utility Model Content

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Reference Figures 1-3 This utility model provides a folding swing arm exhaust gas extraction device, comprising:

[0032] The double folding arm includes a longitudinal rod 1, a first connecting arm 2, and a second connecting arm 3. The first connecting arm 2 is rotatably connected to the top of the side wall of the longitudinal rod 1 through a rotating hinge mechanism, and the second connecting arm 3 is rotatably connected to the first connecting arm 2 through a rotating arm connecting mechanism.

[0033] The exhaust gas extraction pipeline includes an intake pipe 4, an intermediate pipe 5, and an exhaust pipe 6. The exhaust pipe 6 and the intake pipe 4 are respectively fixed to both ends of the intermediate pipe 5 via flexible telescopic pipes 7. The exhaust pipe 6 is installed on the first connecting arm 2, and the intermediate pipe 5 is installed on the second connecting arm 3. The dimensions of the intake pipe 4, the intermediate pipe 5, the exhaust pipe 6, and the flexible telescopic pipe 7 can be adjusted according to the actual operating conditions, and are not specifically limited in this embodiment.

[0034] Spring balancer 8 is mounted on the second connecting arm 3, and air intake pipe 4 is mounted on spring balancer 8;

[0035] Exhaust gas collection hood 9 is installed at the end of intake pipe 4 away from intermediate pipe 5;

[0036] The inner cavities of the intake pipe 4, the intermediate pipe 5, and the exhaust pipe 6 are interconnected. The end of the exhaust pipe 6 away from the intermediate pipe 5 is connected to an air extraction device (not shown in the figure). The air extraction device can be a negative pressure fan, an industrial vacuum cleaner, or an exhaust gas pump.

[0037] With this configuration, the present invention adopts a double-folding arm structure. The double-folding arm can rotate flexibly through a rotating hinge mechanism and a rotating arm connection mechanism. The exhaust angle and position of the exhaust pipe can be adjusted according to actual needs, which greatly improves the flexibility and convenience of use. It can cover a wider area, adapt to exhaust emission sources at different locations and angles, and improve exhaust gas collection efficiency.

[0038] In this invention, the first connecting arm 2 can be rotated through a rotating hinge mechanism, and the second connecting arm 3 can be rotated through a rotating arm connecting mechanism. This allows the first connecting arm 2 and the second connecting arm 3 to be folded and fitted together when not in use, effectively reducing space occupation and improving the utilization rate of production space.

[0039] This utility model connects the intake pipe 4, the intermediate pipe 5 and the exhaust pipe 6 through a flexible telescopic pipe 7, which enhances the telescopicity and flexibility; the spring balancer 8 enables the intake pipe to maintain a stable posture and position, and ensures that the exhaust gas collection cover is always in close contact with the exhaust gas outlet when vibration or displacement occurs during engine start-up, thereby improving exhaust gas collection efficiency.

[0040] The scheme is further optimized. The intermediate pipeline 5 includes a horizontal section pipeline, a transition section pipeline and a vertical section pipeline; the horizontal section pipeline and the vertical section pipeline are fixedly connected and connected through the transition section, the horizontal section pipeline is fixedly connected and connected to the exhaust pipeline 6 through a flexible expansion pipe 7, and the vertical section pipeline is fixedly connected and connected to the intake pipeline 4 through another flexible expansion pipe 7.

[0041] The horizontal section of the pipeline is installed on the top of the second connecting arm 3 by means of a clamping assembly, and the vertical section of the pipeline is installed on the side wall of the second connecting arm 3 by means of a guide clamp 10.

[0042] Further optimization of the scheme: the rotating hinge mechanism includes a connecting seat assembly and a first rotating shaft 11. The first rotating shaft 11 is rotatably connected to the connecting seat assembly. The connecting seat assembly is installed on the top of the side wall of the longitudinal rod 1. An end plate 12 is installed at the end of the first connecting arm 2 away from the second connecting arm 3. Connecting wing plates 13 are respectively installed at the top of the first connecting arm 2 and the bottom of the end plate 12. The first rotating shaft 11 is rotatably connected to the two connecting wing plates 13.

[0043] The first rotating shaft 11 rotates within the connecting support 14, thereby enabling the first connecting arm 2 to rotate flexibly relative to the longitudinal rod 1. This allows the entire exhaust gas extraction system to adjust its angle as needed to adapt to different working environments and exhaust gas emission sources.

[0044] The scheme is further optimized. The connecting seat assembly includes two connecting supports 14. Both connecting supports 14 are detachably connected to the top of the side wall of the longitudinal rod 1 by several bolts. The first rotating shaft 11 is rotatably connected to the two connecting supports 14.

The reinforcing rib 18 enhances the structural strength of the first connecting arm 2 and improves its stability and durability during operation.

[0048] Further optimization of the design resulted in the longitudinal rod 1 having an H-shaped cross-section. The H-shaped cross-section of the longitudinal rod 1 can withstand greater loads and vibrations, ensuring the stability and safety of the entire exhaust gas extraction system during operation.

[0049] The design was further optimized by installing a base at the bottom of the longitudinal rod 1.
