Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to an external sound-absorbing and heat-insulating device. Background Art

[0002] Shovel loading equipment is often used in the manufacturing industry. During the operation of the shovel loading equipment, different degrees of temperature will be generated in its internal structure, and most of the heat is generated by the operation of the engine part. The engine is generally connected to a silencer to reduce the volume of the engine output during operation. The existing shovel loading equipment silencer is generally installed inside the engine compartment. During the use of the muffler, there will be smoke or air leakage, which will cause the temperature of the engine exhaust to re-enter the interior of the engine compartment with the airflow, which is easy to increase the temperature inside the engine compartment, thereby causing the equipment to become high temperature, and then the surface temperature of the muffler will rise. If leaked oil is sprayed upwards at this time, fire and other safety accidents are likely to occur.

[0003] Based on the above situation, it is necessary to design an external sound-absorbing and heat-insulating device to solve the above problems. Utility Model Content

[0026] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0027] Reference Figures 1-9As shown, the external silencer and heat insulation device includes a bin body 1 and an engine body 2 installed inside the bin body 1. The engine body 2 is an existing equipment and will not be described in detail. Its main purpose is to provide power for the shoveling equipment. During the operation of the shoveling equipment, due to the long service life of its internal structural parts, some heat-insulating structural parts of the engine body 2 will show different degrees of wear and aging, which will lead to air leakage and poor heat dissipation during operation. The hydraulic oil temperature and water temperature in the shoveling equipment continue to rise with the temperature of the engine, which can easily cause aging of the internal seals of the hydraulic system and oil leakage in the engine. If the muffler body 4 and the pipe 3 are both located inside the bin body 1, fire and other accidents are very likely to occur.

[0028] It also includes a pipe 3, a muffler body 4 and a fixing assembly for installing the muffler and heat insulation device of the engine body 2 on the outside of the compartment 1.

[0029] Specifically, the input end of the pipe 3 extends to the inside of the warehouse body 1 and is connected to the exhaust outlet of the engine body 2, and the output end of the pipe 3 extends to the outside of the warehouse body 1. The gas exhausted by the engine body 2 will be discharged along the input end of the pipe 3 to the output end.

[0030] The muffler body 4 is installed outside the bin body 1 , the output end of the pipe 3 is connected to the input end of the muffler body 4 , and the input end of the muffler body 4 receives the exhaust gas discharged from the output end of the pipe 3 .

[0031] The above-mentioned silencer mechanism is an existing technical solution. The silencer mechanism is a mechanism specially designed for silencing the engine. It is used to reduce the noise generated when the engine is running and ensure that the exhaust gas can be discharged safely and effectively. These silencers are usually installed at the outlet of the engine exhaust pipe. Through the internal sound-absorbing materials and silencer technology (existing technical solution, not shown in the figure), the noise level of engine emissions is effectively reduced, thereby reducing the impact on the operator and the surrounding environment, while the silencer itself can withstand high-temperature gas.

[0032] The fixing assembly is used to fix the pipe fitting 3 and the muffler main body 4 on the warehouse body 1 . The fixing assembly can stably fix the pipe fitting 3 and the muffler main body 4 on the warehouse body 1 .

[0033] Among them, the fixing assembly includes several stabilizing frames 5 connected to the warehouse body 1 and a supporting cylinder 6 and a protective cylinder 7 fixedly connected to the stabilizing frames 5. The supporting cylinder 6 and the protective cylinder 7 are respectively arranged on the outside of the pipe 3 and the muffler body 4. The supporting cylinder 6 is used to carry and protect the pipe 3 located outside the warehouse body 1, and the protective cylinder 7 is used to carry and protect the muffler body 4.

[0034] Reference Figure 5-6As shown, further, the support cylinder 6 in the fixed assembly includes a support member 61 connected to the stabilizing frame 5 and a support member 62 movably connected to the support member 61. The support member 61 and the support member 62 are both provided with sound insulation cotton 8 and a thermal insulation pad 9. The inner wall of the thermal insulation pad 9 is in contact with the outer surface of the pipe 3. The sound insulation cotton 8 is located outside the thermal insulation pad 9. The thermal insulation pad 9 can prevent the temperature on the pipe 3 from being transferred to the support cylinder 6 to prevent people from being burned when touching it, and the sound insulation cotton 8 is located between the inner wall of the support cylinder 6 and the thermal insulation pad 9. The sound insulation cotton 8 is mainly used to reduce the noise generated by the vibration of the pipe 3 itself, and the vibration of the pipe 3 is mainly caused by the flow of exhaust gas inside the pipe 3 and the vibration of the shoveling equipment affecting the pipe 3.

[0035] Reference Figure 7-8 As shown, further, the protective cylinder member 7 in the fixing assembly includes a protective member 71 connected to the stabilizing frame 5 and a protective member 2 72 movably connected to the protective member 71. The protective member 71 is connected to an arc plate 710 for supporting the muffler body 4. When the muffler body 4 is placed on the protective member 71, it will be located on the arc plate 710 and will not directly contact the protective member 71. The protective member 2 72 is provided with a heat insulation plate 720 for blocking the heat transfer from the surface of the muffler body 4. The heat insulation plate 720 prevents the temperature of the protective member 2 72 itself from being affected by the muffler body 4, thereby preventing people from getting burned when touching the protective member 2 72, and An arc-shaped plate 2 721 is fixedly connected to the inner wall of the heat insulation plate 720, a plurality of long holes 10 are provided on the protective part 1 71, a ventilation hole 11 for air circulation inside the protective cylinder 7 is provided on the arc-shaped plate 1 710, and an air vent with a function similar to that of the ventilation hole 11 is provided on the arc-shaped plate 2 721. The purpose of the ventilation hole 11 and the air vent is to maintain air circulation inside the protective cylinder 7 so that the heat emitted from the surface of the muffler is taken away during the flow of air. Baffles 16 are provided on both sides of the protective part 1 71, and the baffles 16 can prevent moisture from invading the protective part 1 71 from the side, and then invading the inside of the protective cylinder 7 through the long holes 10.

[0036] The long holes 10 on the protective member 1 71 ensure the flow of air inside the protective cylinder 7, thereby achieving the purpose of heat dissipation, while the protective member 2 72 is designed to prevent moisture from invading the protective cylinder 7 from above, thereby preventing the muffler body 4 from being corroded by moisture. In addition, the protective cylinder 7 and the supporting cylinder 6 provide protection for the muffler body 4 and the pipe 3 respectively, so that both are protected from damage by impact from foreign objects.

[0037] When the above structure is in use, when the pipe fitting 3 and the silencer main body 4 are placed on the warehouse body 1, the pipe fitting 3 will contact the thermal insulation pad 9 inside the support member 61. When the pipe fitting 3 is placed on the support member 61, the silencer main body 4 is located on the protective member 71 and supports the arc plate 710, and the input end of the silencer main body 4 is docked with the output end of the pipe fitting 3. When the input end of the pipe fitting 3 is docked and placed with the exhaust outlet of the engine body 2, the input end of the pipe fitting 3 can be docked and fixed with the engine body 2, and the output end of the pipe fitting 3 can be docked and fixed with the silencer main body 4. Then, the protective member 2 72 is connected and fixed with the protective member 1 71, and the support member 2 62 is connected and fixed with the support member 1 61. At this time, the support cylinder 6 and the protective cylinder 7 respectively cover the pipe fitting 3 and the silencer main body 4.

[0038] Among them, reference Figure 1-3 As shown, a slot 12 is provided on the warehouse body 1 for connecting the inside and the outside, and the output end of the pipe 3 extends to the outside of the warehouse body 1 through the slot 12. In order to prevent the pipe 3 from vibrating with the operation of the shoveling equipment during operation, an anti-vibration ring 13 is connected to the slot 12, and a soft ring-shaped pad 14 is fixedly connected to the inner wall of the anti-vibration ring 13, and the ring-shaped pad 14 is in active contact with the outer surface of the pipe 3. When selecting the ring-shaped pad 14, a polymer material with high temperature resistance, wear resistance and elasticity is selected, such as perfluoroether rubber, borosilicate rubber and the like. These materials are existing technical solutions and will not be repeated. When the pipe 3 vibrates, the ring-shaped pad 14 can effectively prevent the vibration amplitude of the pipe 3 and reduce the collision between the pipe 3 and the warehouse body 1, thereby avoiding damage to the pipe 3 due to collision.

[0039] Reference Figure 1 As shown, finally, because the surface of the shoveling equipment is not flat, when the silencer body 4 is installed on the shoveling equipment, the uneven installation method is not conducive to the later maintenance of the silencer body 4 by personnel, so a supporting plate 15 is provided under the silencer body 4, and the supporting plate 15 is connected to the outside of the warehouse body 1. The supporting plate 15 is convenient for personnel to stand and perform maintenance operations.
