Description

Technical Field

[0001] This utility model relates to the technical field of snowplow carriage devices, and in particular to a special folding-wing carriage assembly for a hot-blowing snowplow. Background Technology

[0002] Global climate change has led to more frequent extreme weather events, and snow and ice disasters have severely hampered traffic flow and safety due to road snow accumulation and icing, posing a serious challenge to emergency rescue, material transportation, and daily travel. Traditional mechanical snow removal methods are inefficient when faced with deep snow or compacted ice, while thermal blowing snow removal technology, with its high-temperature, high-speed airflow properties that melt and peel away ice and snow, has become a key means of clearing stubborn snow.

[0003] Hot-blown snowplows use retired aircraft engines (operational engines) as their core power source. These engines are large and consume a lot of fuel, requiring them to be installed inside the vehicle compartment along with the fuel tank. However, most existing hot-blown snowplows use a rear-opening compartment design, resulting in extremely cramped space after the operation engine and fuel tank are installed. This severely impacts the daily maintenance and troubleshooting operations for technicians. Furthermore, the operation engine requires a continuous air intake, which the structure of ordinary enclosed compartments cannot meet, directly limiting the snowplow's operational performance and rapid response capability. Therefore, optimization and improvement of the compartment structure are urgently needed. Utility Model Content

The outer surface of the air intake window is equipped with a rainproof eave, which extends outward along the upper edge of the air intake window and is integrally formed with the folding door.

[0009] The folding-wing body assembly for the hot-blowing snowplow also includes a foldable ladder, which is installed on the rear outer wall of the rear compartment. The foldable ladder includes a ladder assembly and a handrail assembly. The ladder assembly includes a ladder top plate, a long ladder, a short ladder, a pull rod, and a pull plate.

A protective net is provided on the inner side of the hollow rear compartment wall. The protective net is fixedly connected to the hollow rear compartment wall by pressure strips. The mesh diameter of the protective net is smaller than the diameter of the hollow holes.

[0011] The front compartment has a front compartment cover, and the rear compartment has a rear compartment cover. Both the front and rear compartment covers have pedestrian openings on their panels.

Compared with the traditional rear-opening cargo box, the first and second folding wing doors cover the front and rear cargo boxes along the length of both sides of the cargo box. They are opened by rotating upwards through the folding wing drive mechanism, completely opening the space on both sides of the cargo box. This directly exposes the internal equipment of the front cargo box (fuel tank compartment) and the rear cargo box (engine compartment), solving the problem of inconvenient maintenance caused by the cramped space after the engine and fuel tank are installed, and significantly improving the efficiency of fault diagnosis and parts replacement.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this application. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This application provides a folding-wing body assembly specifically for a hot-blowing snowplow, exemplarily, such as... Figures 1-6As shown, it includes: a carriage body 1, a first folding door 2, a second folding door 3, a folding drive mechanism 4, and an air intake window 5; the carriage body includes a front carriage 11 and a rear carriage 12, the front carriage 2 being the working engine fuel tank compartment, and the rear carriage 3 being the working engine compartment, the front carriage 2 and the rear carriage 3 being fixedly connected sequentially along the length of the vehicle; the first folding door 2 is installed on the first side wall of the carriage body 1 via a hinge structure, and the second folding door 3 is installed on the second side wall of the carriage body 1 opposite to the first side wall via a hinge structure. The second wing door 3 covers the corresponding side walls of the front compartment 11 and the rear compartment 12 along the length of the compartment body 1; the wing drive mechanism 4 is provided in two sets, and the two sets of wing drive mechanisms 4 are respectively connected to the first side wall of the compartment body 1 and the first wing door 2, and the second side wall of the compartment body 1 and the second wing door 3, for driving the first wing door 2 and the second wing door 3 to rotate upward or downward around the hinge structure to open or close; the air intake window 5 is opened on the plate of the first wing door 2 and the second wing door 3, and the air intake window 5 is distributed at intervals along the height direction of the wing door.

[0021] The main body of the vehicle is divided into a front compartment 11 (operating engine fuel tank compartment) and a rear compartment 12 (operating engine compartment), which are fixedly connected sequentially along the length of the vehicle to form a distribution layout of fuel tank and engine. The front compartment 11 independently carries the fuel tank, while the rear compartment 12 is dedicated to housing the operating engine, achieving physical isolation between fuel storage and power equipment, and reducing safety risks.

[0022] The first folding door 2 and the second folding door 3 are respectively installed on the opposite side walls of the carriage body 1 via a hinged structure, and cover the corresponding side walls of the front and rear carriages along the length direction. In the open state, the folding doors rotate upward around the hinged structure, exposing the entire space on both sides of the carriage. Technicians can directly access the fuel tank of the front carriage 11 and the working engine of the rear carriage 12 from the side, solving the limitation of traditional rear doors that can only be operated from the narrow space at the rear, and greatly improving the convenience of maintenance and repair. Two sets of folding drive mechanisms 4 are correspondingly connected to the side walls of the carriage and the folding doors, providing power for the opening and closing of the doors, ensuring the controllability and stability of the large-size folding door operation.

[0023] Air intake windows 5 are located on the panels of the first and second wing doors and are spaced apart along the height of the doors. These spaced air intake windows 5 create multiple air intake channels, providing sufficient air to the engine operating inside the rear compartment 12 and preventing engine power reduction due to insufficient air intake in traditional sealed compartments. The air intake windows 5 are integrated with the wing doors, eliminating the need for additional air intake vents on the compartment body 1. This ensures air intake functionality without compromising the structural integrity of the compartment. Furthermore, when the wing doors are closed, the basic sealing of the compartment is maintained through the door structure itself.

[0024] As one possible implementation, the folding wing drive mechanism 4 includes an electric cylinder 41, an electric cylinder mounting side plate 42, an electric cylinder mounting plate 43, a rod end spherical bearing 44, and a bearing mounting base 45; the electric cylinder mounting side plate 42 is fixed to the inner side wall of the first folding wing door 2 or the second folding wing door 3, and the electric cylinder mounting plate 43 is fixed to the first side wall or the second side wall of the carriage body 1; one end of the electric cylinder 41 is hinged to the electric cylinder mounting side plate 42, and the other end of the electric cylinder 41 is hinged to the electric cylinder mounting plate 43; the bearing mounting base 45 is fixed to the hinge end of the first folding wing door 2 or the second folding wing door 3, one end of the rod end spherical bearing 44 is coaxially connected to the bearing mounting base 45, and the other end of the rod end spherical bearing 44 is fixed to the frame of the carriage body 1.

[0025] The folding door drive mechanism 4 achieves stable driving and precise operation of the folding door through the coordinated cooperation of its components: the electric cylinder 41 serves as the power source, with its two ends connected to the electric cylinder mounting side plate 42 and the electric cylinder mounting plate 43 respectively via hinges. The electric cylinder mounting side plate 42 is fixed to the inner wall of the first folding door 2 or the second folding door 3, and the electric cylinder mounting plate 43 is fixed to the corresponding side wall of the carriage body 1, forming a force transmission path between the door, the cylinder, and the carriage, ensuring that the extension and retraction force of the electric cylinder 41 can effectively drive the folding door. At the same time, the bearing mounting base 45 is fixed to the hinge end of the folding door and coaxially connected to the rod end spherical bearing 44, while the other end of the rod end spherical bearing 44 is fixed to the frame of the carriage body 1, forming the rotation fulcrum of the folding door. The structural characteristics of the spherical bearing allow for multi-angle rotation, which can adapt to the angle changes during the opening and closing of the folding door.

[0026] For example, the special folding-wing carriage assembly for hot blowing snow removal vehicles also includes a folding-wing locking mechanism, which is a lever-type door lock 6. The lever-type door lock is installed on the bottom edge of the first folding door 2 and the second folding door 3. The lock body of the lever-type door lock 6 is fixed to the folding door, and the latch of the lever-type door lock 6 is fixed to the bottom frame of the carriage body 1. When the folding door is closed, the lever-type door lock and the latch engage.

[0027] The lever-type door lock 6 utilizes the lever principle to generate a large locking force, effectively resisting the impact of vehicle bumps or operational vibrations, preventing the folding door from accidentally loosening, and ensuring a tight fit between the door and the truck bed. This solves the problem of traditional simple locks easily falling off. The tight engagement between the lock body and the latch further reduces the gap between the folding door and the side wall of the truck bed. Combined with the sealing structure at the door hinges, this reduces the intrusion of external rain, snow, and sand into the truck bed, protecting core equipment such as the fuel tank and the operating engine.

[0028] For example, the air intake window 5 is provided with a dust filter. The dust filter is detachably installed on the inside of the air intake window 5 by bolts. The edge of the dust filter 5 is tightly fitted with the inner wall of the air intake window. The outer surface of the air intake window is provided with a rainproof eave. The rainproof eave extends outward along the upper edge of the air intake window and is integrally formed with the folding door.

[0029] The air intake window 5 features a combined design of a dust filter and a rainproof eaves, forming an integrated structure that balances air intake efficiency and protection. The dust filter is removable and bolted to the inside, its edges fitting snugly against the inner wall of the air intake window to effectively intercept solid impurities such as sand and leaves from the air. The outer surface features a rainproof eaves extending outwards from the upper edge, integrally molded with the folding door for a robust structure requiring no additional assembly. The dust filter achieves thorough filtration through a tight fit, preventing impurities from entering the vehicle compartment and corroding core equipment such as the engine and fuel tank, reducing mechanical wear and the risk of malfunction. The removable bolt connection facilitates regular cleaning or replacement of the filter, preventing clogging and ensuring efficient air intake, making it suitable for long-term outdoor operations. The rainproof eaves physically block rain and snow intrusion; the integrated structure ensures strength while preventing leaks at joints, and does not obstruct airflow.

[0030] For example, the folding-wing vehicle assembly for the hot-blowing snowplow also includes a foldable ladder 7, which is installed on the rear outer wall of the rear compartment 12. The foldable ladder 7 includes a ladder assembly and a handrail assembly. The ladder assembly includes a ladder top plate 71, a long ladder 72, a short ladder 73, a pull rod 74, and a pull plate 75. The ladder top plate 71 is fixed to the rear top side of the rear compartment 12. The top end of the long ladder 72 is hinged to the ladder top plate 71, and the top end of the short ladder 73 is hinged to the bottom end of the long ladder 72. Then, one end of the pull rod 74 is hinged to the middle of the short ladder 73, and the other end of the pull rod 74 is hinged to the pull plate 75. The pull plate 75 is fixed to the rear bottom side of the rear compartment 12. The handrail assembly includes a fixed base 76, an upright 77, a handrail 78, and a waist plate 79. The fixed base 76 is fixed to the top of the front compartment 11 and the rear compartment 12. The bottom end of the upright 77 is hinged to the fixed base 76. The top end of the upright 77 is connected to the handrail 78. The waist plate 79 is fixed to the middle of the upright 77.

[0031] For example, the rear end wall of the rear compartment is a perforated rear compartment wall 121. The perforated rear compartment wall 121 has several perforated holes with a honeycomb structure, which are evenly distributed along the plate of the rear compartment wall 121. A protective net is provided on the inner side of the perforated rear compartment wall 121. The protective net is fixedly connected to the perforated rear compartment wall by a pressure strip. The mesh diameter of the protective net is smaller than the diameter of the perforated holes. Similarly, the front end wall of the front compartment is a perforated front compartment wall 112.

[0032] The honeycomb-shaped perforated holes have the properties of large ventilation area and uniform airflow distribution. They can be used as a supplementary air intake channel for the folding door air intake window, forming a three-dimensional air intake system with the side air intake window as the main side air intake and the rear auxiliary air intake. This further meets the demand of the operating engine for a large amount of continuous airflow. Moreover, the uniformly distributed perforation can avoid local airflow turbulence, ensure stable airflow entering the compartment, and reduce interference with engine operation.

[0033] For example, the top of the front compartment is provided with a front compartment cover 111, and the top of the rear compartment is provided with a rear compartment cover 122. Both the front compartment cover 111 and the rear compartment cover 122 have pedestrian openings 113 on their plates. A welding plate 114 is welded to the edge of the pedestrian opening 113. A pedestrian opening cover 115 is fitted over the pedestrian opening 113. The pedestrian opening cover 115 is connected to the welding plate 114 by bolts. A rubber sealing ring 116 is sandwiched between the pedestrian opening cover 115 and the welding plate 114. The rubber sealing ring 116 is arranged circumferentially along the edge of the welding plate 114.

[0034] The manhole provides direct access to the front compartment 11 and rear compartment 12 from the top, forming a comprehensive maintenance system with the side folding doors. For components such as the fuel tank top and engine top piping under the top cover, technicians can directly enter the compartment through the manhole to operate without having to navigate around large equipment from the side, significantly improving maintenance efficiency. The rubber sealing ring, circumferentially positioned along the edge of the welded plate, is tightly compressed to form a sealed area after the manhole cover is bolted on, completely blocking rain, snow, and dust from entering the compartment through the manhole gaps. This sealing design effectively prevents fuel from becoming damp and deteriorating, and engine circuit short circuits, significantly improving equipment operational stability.

[0035] For example, the special folding-wing type body assembly for hot blowing snow removal vehicles also includes a shock-absorbing support structure. The shock-absorbing support structure 8 includes a main bracket 81, shock absorbers 82, and a support frame 83. The main bracket 81 is fixed to the bottom frame of the body 1. Several shock absorbers 82 are provided. Several shock absorbers 82 are respectively installed on both sides of the main bracket 81, the bottom of the front body, and the bottom of the rear body. The top of the support frame 83 is connected to the shock absorbers 82, and the bottom of the support frame 83 is used to fix it to the main beam of the vehicle chassis.

[0036] The main support 81 serves as the basic load-bearing component, providing an installation reference for the shock absorber assembly. Several shock absorbers 82 are distributed to achieve multi-point vibration buffering. The support frame 83 acts as a connecting hub, with its top end docking with the shock absorber 82 and its bottom end used for fixed connection with the main beam of the vehicle chassis, ultimately forming an assembly relationship between the vehicle body 1 and the chassis that combines rigid support and flexible buffering. The core load of the hot-blown snow removal vehicle is concentrated in the front compartment 11 (fuel tank) and the rear compartment 12 (operating engine, such as a retired aircraft engine). During operation, the engine will generate high-frequency vibrations, and when driving on snow-covered or icy roads, chassis bumps will also be transmitted to the vehicle body. The shock-absorbing support structure 8, through the layout of the main support 81 and the multi-point shock absorbers 82 on both sides of the front and rear compartments, can buffer vibrations from different sources in layers: the shock absorbers 82 at the main support 81 absorb the overall vibration of the compartment, while the shock absorbers 82 at the bottom of the front and rear compartments specifically weaken the local vibrations of the fuel tank and engine, avoiding problems such as loosening of pipelines and fatigue wear of components (such as cracking of engine cylinder block and fuel tank welds) caused by long-term high-frequency vibration, and significantly extending the service life of the core equipment.

[0037] As one possible implementation, the hinge structure consists of a rod end spherical bearing and a bearing mounting base. Multiple bearing mounting bases are spaced apart along the top edge of the first wing door 2 and the second wing door 3. Each bearing mounting base is connected to a corresponding rod end spherical bearing. The end of the rod end spherical bearing away from the bearing mounting base is hinged to the top frame of the front and rear compartments.

[0038] The first and second folding doors cover the front and rear compartments along the length of the carriage. These doors are large and heavy, and generate significant torque when opening and closing. By installing multiple bearing mounting bases and spherical bearings at intervals along the top edge, the weight and rotational torque of the folding doors are evenly distributed to multiple support points. This avoids excessive force at a single point, preventing base deformation and bearing damage. It also solves the problem that traditional single-point or few-point hinged joints cannot support long doors, ensuring the structural stability of the door during long-term, high-frequency movements.

[0039] For example, the folding vane assembly for a hot-blowing snowplow also includes a lighting warning system 9, which includes a lighting lamp 91, a warning lamp 92, and a guide indicator 93; the lighting lamp 91 includes The main lighting lamp 91 is fixed to the front end of the front compartment roof 111 and the side lighting lamp on the side wall of the compartment. Multiple warning lights 91 are provided. Multiple warning lights 92 are fixed at intervals on both sides of the front compartment roof 111 and the rear compartment roof 122. The guide indicator light 93 is fixed to the top of the rear of the rear compartment roof 122.

[0040] Hot air snowplows are often used in emergency operations in low visibility environments such as rain, snow, fog, and night. The lights 91 at the front of the front roof 111 can specifically illuminate the road ahead, clearly showing the snow thickness, road obstacles (such as rocks and potholes) and the work boundary, preventing the vehicle from deviating from the work area or colliding due to poor visibility. At the same time, the lighting in this position can also assist technicians in performing equipment inspections near the front of the vehicle (such as cleaning the air intake window and checking the fuel tank interface) without having to carry additional lighting tools, thus improving the convenience of maintenance.

[0041] Multiple spaced warning lights 92 are arranged along the sides of the front and rear roof covers, forming a surrounding warning strip. Compared to single-point warnings, the spaced warning lights 91 eliminate blind spots and improve the comprehensiveness of the warning. The directional indicator lights 93 can clearly convey driving signals such as turning, deceleration, and stopping to oncoming vehicles, solving the problem of traditional vehicle taillights failing due to snow cover.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
