Pipeline fixing structure for unmanned vehicle

Abstract

This invention relates to the field of fire-fighting equipment and spraying equipment extension technology, specifically a pipeline fixing structure for unmanned vehicles. This device can fix the internal pipelines of an unmanned vehicle to counteract traction force when the vehicle is towing a hose over a long distance for fire-fighting and spraying operations. Existing fire-fighting and spraying equipment has limitations in its use in spatial terrain. In high-risk, high-explosive, and complex environments, there are safety hazards for rescue personnel entering or conducting short-distance extension operations. Therefore, it is necessary for unmanned vehicles to extend the distance to tow hoses into the site for operations. This invention designs a stable and easily adjustable pipeline fixing structure for unmanned vehicles to prevent excessive traction force from damaging the internal pipelines, causing liquid leakage and splashing, resulting in insufficient liquid supply for fire-fighting and spraying operations, and damage to the vehicle's mechanical and electrical structures.

Description

Technical Field

[0001] This invention relates to the field of fire-fighting equipment and spraying equipment technology, and in particular to a pipeline fixing structure for unmanned vehicles, which is a device for fixing the internal pipelines of the vehicle body and counteracting the traction force when the unmanned vehicle is dragging a water hose for fire-fighting and spraying operations over a long distance. Background Technology

[0002] Existing firefighting and spraying equipment has limitations in its application to various terrains. In high-risk, high-explosive, and complex environments, the entry of rescue personnel or short-distance extension operations pose safety hazards. Therefore, unmanned vehicles (UAVs) are needed to extend their reach by towing hoses to the site. However, current technology suffers from poor stability of the hose's fixed structure when towing hoses. During long-distance towing, especially with a full hose, its large mass and high friction coefficient against the ground generate significant friction, increasing the traction force on the UAV. This can lead to internal pipe collapse, causing leaks, affecting functionality, and damaging the vehicle's mechanical and electrical structures. Summary of the Invention

[0003] The purpose of this invention is to design a stable and easily adjustable pipeline fixing structure for unmanned vehicles to prevent liquid leakage and splashing caused by excessive traction force damaging the internal pipeline, resulting in insufficient liquid supply for fire fighting and spraying operations and damage to the vehicle's mechanical and electrical structures. This invention includes a reinforcing steel plate, an adjustment mechanism, and a position locking mechanism. The reinforcing steel plate is fixed to the load-bearing crossbeam of the vehicle frame (1) by welding, and has a U-shaped structure with advantages of high tensile strength and good stability. A hole with a diameter larger than the outer diameter of the pipeline (3) is opened in the middle of the reinforcing steel plate. Four through holes are evenly distributed around the middle hole for bolts (5) to pass through. The adjustment mechanism consists of a fixing flange (7) and a guide sleeve (6). The fixing flange (7) and the reinforcing steel plate (8) are fastened to the rear of the vehicle body by bolts (5). The pipeline is inserted into the guide sleeve (6), which passes through the middle hole of the flange. The diameter of the middle hole of the flange is slightly larger than the outer diameter of the guide sleeve (6). When actually installing the pipeline (3), in order to eliminate positional errors, the upper and lower movements of the guide sleeve (6) are adjusted to ensure that the pipeline (3) is connected correctly. Then, the guide sleeve (6) is welded and fixed to the fixed flange (7). The position locking mechanism consists of a locking bracket (2) and a buffer sleeve (4). The buffer sleeve (4) passes through the pipeline axially, and its end face abuts against the guide sleeve (6). The material used is hard rubber, which will be compressed to buffer when subjected to impact. The locking bracket (2) is axially inserted into the pipeline (3) and fits against one end face of the buffer sleeve (4). The pipeline (3) is clamped and positioned by bolts (5). A brass ring is placed at the clamping position of the locking bracket (2) and the pipeline (3) to protect the pipeline (3) and prevent excessive clamping force from damaging the pipeline.

[0010] A pipe fixing structure for unmanned vehicles includes a reinforcing steel plate, an adjustment mechanism, and a position locking mechanism. The reinforcing steel plate is fixed to the load-bearing crossbeam of the vehicle frame (1) by welding. The structure is U-shaped and has the advantages of high tensile strength and good stability. The reinforcing steel plate has a hole in the middle position with a diameter larger than the outer diameter of the pipe (3). Four through holes are evenly distributed around the middle hole for bolts (5) to pass through. The adjustment mechanism consists of a fixed flange (7) and a guide sleeve (6). The fixed flange (7) and the reinforcing steel plate (8) are fastened to the rear of the vehicle body by bolts (5). The pipe is inserted into the guide sleeve (6). The guide sleeve (6) passes through the middle hole of the flange. The diameter of the middle hole of the flange is slightly larger than the outer diameter of the guide sleeve (6). When actually installing the pipe (3), in order to eliminate position errors, the guide sleeve (6) is adjusted up and down to ensure that the pipe (3) is connected correctly. Then the guide sleeve (6) is welded and fixed to the fixed flange (7). The position locking mechanism consists of a locking bracket (2) and a buffer sleeve (4). The buffer sleeve (4) passes through the pipeline axially and its end face abuts against the guide sleeve (6). The material is hard rubber, which will be compressed to buffer when impacted. The locking bracket (2) is inserted into the pipeline (3) axially and fits against one end face of the buffer sleeve (4). The pipeline (3) is clamped and positioned by bolts (5). A brass ring is placed at the clamping position of the locking bracket (2) and the pipeline (3) to protect the pipeline (3) and prevent excessive clamping force from damaging the pipeline.
