Description

Technical Field

[0001] This utility model belongs to the field of railway vehicle technology, specifically relating to a mechanical air conditioner for railway vehicle guards. Background Technology

[0002] A railway watchdog car, also called a lookout car, is attached to the rear of a freight car and used for observing other vehicles and assisting with braking. Currently, on trains, this watchdog car is mounted on a locomotive, which obtains electricity through the overhead contact line to power the air conditioning system. This electricity drives the refrigeration compressor, which compresses Freon to produce refrigeration.

[0003] Therefore, the current problem with railway cars is that they must rely on external power supply or be equipped with their own generators. Mining railway cars do not have overhead contact lines to supply power to the guard cars, and the guard cars cannot be equipped with generators. Therefore, it is impossible to install electric air conditioners on the guard cars of mining railway cars.

[0004] Therefore, this application proposes a mechanical air conditioner for railway guards to solve the above problems. Utility Model Content

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0020] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0021] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Example 1, combined with Figures 1-3This embodiment describes a railway guard mechanical air conditioner, including a guardhouse 1, a wheel mechanism 2, and a guard body 3. The guardhouse 1 and the wheel mechanism 2 are mounted on the guard body 3. The guardhouse 1 is equipped with a first radiator 4 and a second radiator 5. An air compressor 14 and an expansion valve 17 are mounted on the bottom of the wheel mechanism 2. The wheel mechanism 2 is connected to the actuator of the air compressor 14 through a transmission mechanism. The air compressor 14, the first radiator 4, the dryer 5, and the expansion valve 17 are connected in sequence. The second radiator 6 is connected to the expansion valve 17. A magnetic clutch 16 is connected to the actuator of the air compressor 14. The magnetic clutch 16 is connected to a battery 18 through a wire.

[0023] The wheel mechanism 2 includes a rear axle 10, a front axle 11, and side frames 25. There are two sets of side frames 25, which are arranged in a mirror image. The rear axle 10 and the front axle 11 are installed between the two sets of side frames 25. The rear axle 10 and the front axle 11 are rotatably connected to the side frames 25 through bearing seats. Mounting seats 15 are connected between the symmetrically arranged vehicle 25. An air compressor 14 and an expansion valve 17 are installed on the mounting seats 15. The actuator end of the air compressor 14 is equipped with a magnetic clutch 16 and a driven pulley 9. The magnetic clutch 16 is connected to a battery 18 through a wire. The battery 18 is a 24-volt battery. The battery 18 is installed on the side frames 25 and supplies power to the magnetic clutch 16. The driven pulley 9 is connected to the driving pulley 7 through a belt 8. The driving pulley 7 is installed on the rear axle 10. A rear wheel set 12 is installed on the rear axle 10, and a front wheel set 12 is installed on the front axle 11.

[0024] When the guard vehicle body 3 is in motion, the rear wheel set 12 rotates, driving the rear wheel axle 10 to rotate. The rotation of the rear wheel axle 10 drives the drive pulley 7 to rotate, which in turn drives the driven pulley 9 mounted on the air compressor 14 to rotate via the belt 8. The battery 18 powers the magnetic clutch 16, which engages, and the air conditioning system consisting of the air compressor 14, expansion valve 17, first radiator 4, dryer 5, and second radiator 6 begins to work. The second radiator 6, located inside the guard vehicle compartment 1, begins to cool down, and the fan 41 of the wind-driven motor on the first radiator 4 is adjusted to control the amount of cold air.

[0025] The first low-pressure gas inlet 19 on the air compressor 14 is connected to the first low-pressure gas outlet 22 of the expansion valve 17 via a high-pressure copper pipe. The high-pressure gas outlet 20 on the air compressor 14 is connected to the high-pressure gas inlet 43 on the first radiator 4 via a high-pressure copper pipe. The first high-pressure liquid inlet 21 on the expansion valve 17 is connected to the second high-pressure liquid outlet 52 on the dryer 5 via a copper pipe. The low-pressure liquid outlet 24 on the expansion valve 17 is connected to the low-pressure liquid inlet 61 on the second radiator 6 via a high-pressure copper pipe. The second low-pressure gas inlet 23 on the expansion valve 17 is connected to the second low-pressure gas outlet 62 on the second radiator 6 via a high-pressure copper pipe. The second high-pressure liquid inlet 51 on the dryer 5 is connected to the first high-pressure liquid outlet 44 on the first radiator 4 via a high-pressure copper pipe.

[0026] This embodiment is merely an exemplary illustration of this application and does not limit its scope of protection. Those skilled in the art can make partial changes to it, as long as they do not exceed the spirit and essence of this application, they are all within the scope of protection of this application.
