Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation ducts of fan testing machines, and particularly relates to a ventilation duct of a locomotive fan testing machine. Background Art

[0002] The locomotive fan test is one of the key links to ensure the safe operation of railway locomotives. As an important component of the locomotive, the fan is mainly responsible for providing necessary ventilation and cooling to ensure the normal operation of locomotive electronic equipment in high-temperature environments. At the same time, during emergency braking, it may also participate in the process of transmitting the air braking force of the locomotive.

[0003] There are some deficiencies in the design of the ventilation ducts of existing locomotive fan testing machines. After the ventilation ducts are connected, they are relatively large in volume and inconvenient to move. Moreover, the movement of a single section of the duct is also very inconvenient during movement. In addition, most of the connections between the ventilation ducts are made by flanges, which require a large number of bolts for fixation. Therefore, a large amount of time is wasted on fixing the bolts during installation.

[0004] Therefore, we provide a ventilation duct for a locomotive fan testing machine to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a ventilation duct for a locomotive fan testing machine. By setting universal wheels at the bottom of the duct body, it is convenient to move the entire duct. In addition, a telescopic rod is provided between the universal wheels. When the telescopic rod touches the ground, it will lift the universal wheels, thereby completing the fixation of the duct, solving the problem of inconvenient movement of the existing duct.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model is a ventilation duct for a locomotive fan testing machine, including

[0008] a duct component, including a duct body, holes opened around the top of the duct body, and a resisting block arranged inside the duct body;

[0009] a moving component including a fixing component arranged at the bottom of the duct body, an adjusting component arranged above the fixing component, a supporting component arranged at the bottom of the fixing component, and a power component arranged outside the supporting component;

[0010] The fixing component includes a fixing frame arranged at the bottom of the duct body, a cross bar arranged in the middle of the fixing frame, a bearing frame arranged at the bottom of the fixing frame, and universal wheels respectively arranged at the four corners of the bottom of the bearing frame;

[0011] The support assembly includes a fixed sleeve disposed at the bottom of the carrier, a telescopic rod sleeved inside the fixed sleeve, and a support foot disposed at the bottom of the telescopic rod;

[0012] The power assembly includes a first connecting rod disposed on both sides of the fixed sleeve, a pressing rod sleeved outside the first connecting rod, a second connecting rod disposed outside the first connecting rod and below the pressing rod, and a pedal disposed at the other end of the second connecting rod.

[0013] The present utility model is further configured such that the adjusting assembly includes a screw rod passing through the fixed frame and the cross bar, a connecting block disposed at the top of the screw rod, a V-shaped rod disposed at the top of the connecting block, and a connecting block sleeved outside the screw rod.

[0014] The present utility model is further configured such that the fixed sleeve is fixedly connected to the bottom end of the carrier and is located at the midline of the carrier. The telescopic rod is slidably connected to the fixed sleeve, and the support foot is fixedly connected to the telescopic rod.

[0015] The present utility model is further configured such that the first connecting rod is rotatably connected to the power assembly. The corner of the second connecting rod is connected to the telescopic rod through a connecting rod, and the first connecting rod is fixedly connected to the pressing rod.

[0016] The present utility model is further configured such that the screw rod is threadedly connected to a nut. The nut is fixedly connected to the fixed frame, and the screw rod is rotatably connected to the connecting block.

[0017] The present utility model is further configured to further include a mounting component, which includes a mounting assembly sleeved outside the pipe body and a dismounting component disposed outside the pipe body.

[0018] The present utility model is further configured such that the mounting assembly includes a sliding sleeve disposed on the outer wall of the pipe body, an expanded space opened inside the sliding sleeve, a fixed ball disposed inside the sliding sleeve, a receiving ring disposed at the end of the pipe body, and an adapter ring opened outside the receiving ring.

[0019] The present utility model is further configured such that the dismounting component includes a guide rail disposed on the outer wall of the pipe body, a connecting rod disposed inside the guide rail, a vertical plate disposed at the top end of the guide rail, and a pull rod disposed inside the vertical plate. Wherein, the other end of the connecting rod is fixedly connected to the sliding sleeve.

[0020] The present utility model has the following beneficial effects:

[0021] 1. The utility model facilitates the movement of the pipeline by setting universal wheels. Additionally, support feet are arranged between the universal wheels. By stepping on the pedal, the telescopic rod moves downward, and the support feet come into contact with the ground. Continuing to step on the pedal makes the first connecting rod and the second connecting rod form a straight line, so that the support feet can stably support the pipeline. These two processes facilitate both the movement and the fixation of the pipeline.

[0022] 2. The utility model pulls the connecting rod to move the connecting rod, and the movement of the connecting rod pulls the sliding sleeve to move. After the sliding sleeve moves, the expansion space returns to the position of the fixed ball, so that it no longer gets stuck in the adapter ring of another pipeline, thus completing the disassembly of the two pipelines. On the contrary, pushing the connecting rod in the opposite direction makes the sliding sleeve return to its original position, causing the fixed ball to move inward and get stuck inside the adapter ring, completing the splicing of the two pipeline sections.

[0023] Of course, it is not necessary for any product implementing the utility model to achieve all the above-mentioned advantages simultaneously. BRIEF DESCRIPTION OF THE DRAWINGS
