Description

Technical Field

[0001] The utility model belongs to the technical field of engineering machinery vehicles, and in particular relates to an air-conditioning indoor unit for an engineering machinery vehicle with a pipeline protection mechanism. Background Art

[0002] Construction vehicles are widely used in various engineering and construction fields, performing diverse tasks such as excavation, transportation, loading, leveling, and compaction. With technological advancements and the continuous development of engineering construction, construction vehicles are constantly innovating and improving. In the future, construction vehicles will place greater emphasis on intelligent, automated, and environmentally friendly development. For example, by incorporating advanced sensors, controllers, and actuators, they will enable remote monitoring, automated navigation, and intelligent operation. Furthermore, they will employ more environmentally friendly energy and emission control technologies to reduce their environmental impact.

[0003] The cabs of construction vehicles are typically equipped with an indoor air conditioning unit. This unit works closely with an outdoor unit mounted outside the vehicle to efficiently regulate the cabin temperature, providing a comfortable working environment for the driver, whether in the scorching summer or the cold winter, achieving both cooling and warmth. However, it's worth noting that construction vehicles are often subject to significant overall vibration during operation. This vibration not only tests the durability of the vehicle but also poses challenges to the stable operation of the air conditioning system. The connecting pipes extending from the indoor unit to the outside of the vehicle are particularly susceptible to severe friction due to prolonged exposure to vibration. If timely protective measures are not taken, this constant friction will gradually wear out the connecting pipes, resulting in a decrease in their sealing performance and even possible refrigerant leakage. This will seriously affect the normal operation of the indoor unit, reduce the performance of the entire air conditioning system, and adversely affect the driver's comfort and work efficiency. Utility Model Content

[0004] The purpose of the present utility model is to provide an indoor unit of an air conditioner for an engineering machinery vehicle with a pipe protection mechanism, aiming to solve the problem that engineering machinery vehicles are often accompanied by large overall vibrations during operation. This vibration not only tests the durability of the vehicle, but also poses a challenge to the stable operation of the air conditioning system. In particular, the connecting pipe portion of the indoor unit extending to the outside of the vehicle is extremely susceptible to severe friction due to being in a vibrating environment for a long time. If measures are not taken in time to protect it, this continuous friction will gradually wear out the connecting pipe, resulting in a decrease in its sealing performance, and may even cause problems such as refrigerant leakage, which will seriously affect the normal operation of the indoor unit, reduce the performance of the entire air conditioning system, and have an adverse effect on the driver's comfort and work efficiency.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an indoor air conditioner unit for an engineering vehicle with a pipeline protection mechanism, comprising an indoor air conditioner unit, a mounting plate being mounted on the back of the indoor air conditioner unit, an external pipeline being connected to one side of the indoor air conditioner unit, and a sleeve being sleeved on the outer wall of the external pipeline near the connection portion with the indoor air conditioner unit;

[0006] A clamping sleeve is sleeved on the outer wall of the sleeve, and a fixing piece is movably connected to both sides of the clamping sleeve. One side of each fixing piece is welded to the surface of the mounting plate, and the sleeve is mounted on the mounting plate through the clamping sleeve.

[0007] In order to enable the ferrule to fix the sleeve in the installation position, as the preferred embodiment of the utility model of the engineering machinery vehicle air-conditioning indoor unit with a pipeline protection mechanism, two limit strips are fixedly connected to the outer wall of the butt end of the sleeve and the ferrule, and the other end of the sleeve is provided with an arc-shaped port, and a side block is fixedly connected to each side of the ferrule, and two notches are provided on the side block and the connecting end of the sleeve, and the two limit strips are adapted to the two notches on the ferrule.

[0008] To ensure stable installation of the ferrule between two fixings, a preferred embodiment of the utility model of an engineering vehicle air conditioner indoor unit with a pipe protection mechanism is a ferrule with a threaded hole at one end and a bayonet extending through one side of the fixing. The bayonet has internal dimensions that match those of the side block, and the ferrule is installed between the two fixings via the side block and the bayonet.

[0009] Compared with the prior art, the beneficial effects of the present invention are:

[0010] After the air-conditioning indoor unit is installed in the cab of the construction machinery vehicle, it is necessary to pass the external pipe on the air-conditioning indoor unit out of the cab of the construction machinery vehicle. When passing through the external pipe, first put the sleeve on the outer wall of the external pipe, and then fix the sleeve to the joint part of the air-conditioning indoor unit and the external pipe through the cooperation between the clamp and the fixing part. In this way, an effective protective structure can be formed at the connection between the air-conditioning indoor unit and the external pipe. In this way, when the construction machinery vehicle drives the air-conditioning indoor unit and the external pipe to vibrate during operation, friction can be prevented at the connection between the air-conditioning indoor unit and the external pipe, thereby preventing damage to the external pipe.

[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only 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 making creative efforts are within the scope of protection of the present invention.

[0019] See also Figure 1-5 , the utility model provides the following technical solutions: an air-conditioning indoor unit for an engineering machinery vehicle with a pipeline protection mechanism, comprising an air-conditioning indoor unit 1, a mounting plate 2 being mounted on the back of the air-conditioning indoor unit 1, and an external pipeline 3 being connected to one side of the air-conditioning indoor unit 1. When in use, the mounting plate 2 on the back of the air-conditioning indoor unit 1 is aligned with the mounting position in the cab of the engineering machinery vehicle, the mounting plate 2 is provided with mounting holes, and when installing, bolts are passed through the mounting holes of the mounting plate 2 and docked with the corresponding mounting points in the cab of the engineering machinery vehicle, thereby enabling the air-conditioning indoor unit 1 to be installed in the cab of the engineering machinery vehicle. When in use, the air-conditioning indoor unit 1 can effectively provide protection for the cab of the engineering machinery vehicle through cooperation with the corresponding external unit;

[0020] A sleeve 4 is sleeved on the outer wall of the external pipe 3 near the connection portion with the air conditioner indoor unit 1;

[0021] A clamping sleeve 5 is sleeved on the outer wall of the sleeve 4, and a fixing piece 6 is movably connected to both sides of the clamping sleeve 5. One side of each fixing piece 6 is welded to the surface of the mounting plate 2, and the sleeve 4 is installed on the mounting plate 2 through the clamping sleeve 5.

[0022] Preferably, two limiting strips 401 are fixedly connected to the outer wall of the butt joint of the sleeve 4 and the ferrule 5, and an arc-shaped port 402 is provided at the other end of the sleeve 4. A side block 501 is fixedly connected to each side of the ferrule 5, and two notches 502 are provided at the connection end between the side block 501 and the sleeve 4. The two limiting strips 401 are adapted to the two notches 502 on the ferrule 5.

[0023] The sleeve 4 is made of hard rubber, and the inner diameter of the sleeve 4 is slightly smaller than the outer diameter of the external pipe 3 . Therefore, when the sleeve 4 moves on the external pipe 3 , the operator needs to use a larger pulling force to enable it to move normally on the external pipe 3 .

[0024] In specific use, when the sleeve 4 is installed in the external pipe 3, the two limit bars 401 on the sleeve 4 need to be set outward, and then the two notches 502 at the bottom of the ferrule 5 are clamped on the outer wall of the corresponding limit bars 401, and the ferrule 5 and the sleeve 4 are moved at the same time;

[0025] When the sleeve 4 moves to the connection end of the external pipe 3 and the air-conditioning indoor unit 1, it stops moving, and when moving, the side blocks 501 on both sides of the sleeve 5 should be connected to the corresponding fixing parts 6 on the mounting plate 2, and then the sleeve 5 should be fixed between the two fixing parts 6. In this way, a protective structure can be formed on the connection part of the external pipe 3 and the air-conditioning indoor unit 1 through the sleeve 4. In this way, when the engineering machinery vehicle drives the air-conditioning indoor unit 1 and the external pipe 3 to vibrate during operation, friction can be prevented at the connection between the air-conditioning indoor unit 1 and the external pipe 3, thereby preventing the external pipe 3 from being damaged.

[0026] Preferably, a threaded hole 601 is provided at one end of the fixing member 6, and a bayonet 602 is provided on one side of the fixing member 6. The inner size of the bayonet 602 matches the size of the side block 501, and the ferrule 5 is installed between the two fixing members 6 through the side block 501 and the bayonet 602.

[0027] The side block 501 is provided with a through hole having the same size as the threaded hole 601. When the side block 501 is fully inserted into the threaded hole 601, the through hole on the side block 501 and the threaded hole 601 are located at the same position. At this time, the installer inserts the bolt into the threaded hole 601 from the opening on one side of the threaded hole 601. As the installation steps are further performed, the bolt is rotated to connect the threaded hole 601 and the through hole, so that the side block 501 will be fixed in the bayonet 602.

[0028] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
