Description

Technical Field

[0001] This application relates to the field of single-unit engine testing technology, specifically to a single-unit engine testing auxiliary device. Background Technology

[0002] An engine is a machine that can convert other forms of energy into mechanical energy. After an engine is designed and manufactured, it needs to undergo corresponding data testing, including a series of data such as engine speed, torque, and cylinder pressure.

[0003] According to Chinese announcement number CN222212256U, a single-unit engine testing auxiliary device includes a support platform. A guide bar is fixedly connected to the top of the support platform, a load is movably connected to the top of the support platform, and a movable seat is movably connected to the top of the support platform. A torque sensor is fixedly connected to the top of the movable seat. By setting up the support platform, the load and torque sensor can be easily supported movably, allowing for docking with the engine shaft. The movable platform can be raised and lowered by a hydraulic cylinder according to the size of the engine being tested, thus adjusting to allow docking with the engine shaft for testing, improving convenience. Furthermore, by placing the engine to be tested on the movable platform and rotating a bidirectional screw, two limit plates can be adjusted to limit the movement of both sides of the engine, thereby improving stability during testing.

[0004] During the testing process, the single-unit engine needs to be kept running. During operation, the single-unit engine is affected by the surrounding environment. In low-temperature and high-temperature environments, the oil viscosity will increase and the lubrication effect will decrease. In high-temperature environments, the heat dissipation pressure will increase, which may lead to engine overheating and reduced fuel efficiency, thus affecting the operation of the single-unit engine.

In addition, when the heating wire component is not in use, it can be stored to prevent dust from adhering to the surface of the heating wire component, thereby affecting the heating effect. Furthermore, by storing the heating wire component, the intake fan can be increased during cooling, thereby achieving better heat dissipation. Attached Figure Description

Detailed Implementation

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] This application provides a technical solution: such as Figures 1-4 The single-unit engine testing auxiliary device shown includes: a main body of the testing auxiliary device, a ventilation and heat dissipation component 4, and a housing and heating component 5. The main body of the testing auxiliary device includes a testing component 1, a lifting component 2 disposed on one side of the testing component 1, and a clamping and fixing component 3 disposed directly above the lifting component 2. The ventilation and heat dissipation component 4 is disposed outside the clamping and fixing component 3, and the housing and heating component 5 is disposed on the outer wall of the ventilation and heat dissipation component 4.

[0025] The ventilation and heat dissipation component 4 includes a hinge 401 with one end set on one side of the outer wall of the lifting component 2, and a protective cover 402 set on the other end of the hinge 401. The protective cover 402 is set directly above the lifting component 2. An air inlet pipe and an air outlet pipe are respectively set on both sides of the protective cover 402. A sliding hole is opened at the top of the air inlet pipe of the protective cover 402. An exhaust fan 403 and an air inlet fan 404 are set on the inner wall of the air outlet pipe of the protective cover 402. A first connecting block 405 is rotatably set on one side of the outer wall of the lifting component 2 with one end rotatably connected by a shaft. A second connecting block 406 is set on one side of the outer wall of the protective cover 402 with one end rotatably connected by a shaft. An electric hydraulic rod 407 is set on the outer wall of the first connecting block 405 and the second connecting block 406 with both ends respectively.

[0026] The heating and storage assembly 5 includes a storage box 501 welded to the top outer wall of the protective cover 402. The storage box 501 has an internal cavity and is connected to the sliding hole of the protective cover 402. A strip-shaped hole is provided on one side of the outer wall of the storage box 501. A heating wire assembly 502 is vertically slidably arranged inside the cavity of the storage box 501. The heating wire assembly 502 consists of a frame and multiple sets of electric heating wires inside the frame. A fixing rod 503 is welded to the outer wall of the frame of the heating wire assembly 502 and is slidably arranged inside the strip-shaped hole of the storage box 501. A drive motor 504 is fixed on the outer wall of the storage box 501. A connecting shaft 505 is provided on the output end of the drive motor 504. A toggle block 506 is provided on the connecting shaft 505. A hole is provided inside the toggle block 506 and the fixing rod 503 is provided in the hole of the toggle block 506.

[0027] Working principle: The clamping and fixing component 3 can clamp and fix individual engines of different specifications. In conjunction with the lifting component 2 at the bottom, it can provide height adjustment for the clamped individual engine, so that the individual engine can be aligned with the test component 1 for subsequent testing. According to the outdoor ambient temperature, the temperature of the individual engine during operation can be adjusted. At this time, the ventilation and heat dissipation component 4 and the heat storage component 5 can quickly operate according to the ambient temperature.

[0028] When the outdoor ambient temperature is high, the electric hydraulic rod 407 operates. Both ends of the electric hydraulic rod 407 are connected to the first connecting block 405 and the second connecting block 406, which are respectively connected to the protective cover 402 and the lifting assembly 2 via rotating shafts. When the electric hydraulic rod 407 pushes at its output end, it causes the protective cover 402 to change angle via the hinge 401, thereby ensuring that the bottom of the protective cover 402 is directly above the lifting assembly 2. The protective cover 402 can cover and protect the single engine that is clamped and fixed by the clamping and fixing component 3. The air intake pipe and exhaust pipe at both ends of the protective cover 402 can form an air duct, and the protective cover 402 can isolate external dust by itself to prevent dust from adhering to the single engine. At this time, the air intake fan 404 is started to deliver outside air to the inside of the protective cover 402. The air delivered to the protective cover 402 will quickly exhaust the high temperature through the exhaust fan 403, thereby cooling the single engine.

[0029] When facing low temperatures, the drive motor 504 is activated. The drive motor 504 will drive the connecting shaft 505 on the output end to change its angle. At this time, the connecting shaft 505 will simultaneously drive the toggle block 506 to change its angle. Because the toggle block 506 has a fixing rod 503 inside, the heating wire assembly 502 connected to the fixing rod 503 will simultaneously move vertically downward inside the storage box 501, so that the heating wire assembly 502 is inside the air intake pipe of the protective cover 402. When the heating wire assembly 502 is working, the air intake fan 404 delivers the temperature to the inside of the protective cover 402, thereby regulating the temperature of the individual engine inside the protective cover 402.
