Description

Technical Field

[0001] This application applies to the field of snowplows, specifically relating to an explosion-proof snowplow. Background Technology

[0002] Snowplows are commonly used in northern regions. Driven by locomotives, they have front-mounted snow-clearing wheels that can sweep large areas of snow to one side. However, snowplows are also currently used in some explosive gas environments, such as airport oil depots and oil refineries. When operating in these areas, snowplows suffer from poor adaptability to overlapping equipment and insufficient safety protection, making them highly susceptible to explosions and posing a serious threat to equipment, personnel, and the surrounding environment. The main reasons are as follows:

[0003] (1) The electrical equipment such as motors, lines, and switches of conventional snowplows are not designed to be explosion-proof. During operation, electric sparks may be generated due to leakage, short circuit, or arc discharge (such as contactor operation). When explosive gases (such as methane, propane, gasoline vapor, etc.) mix with air and reach the explosion limit, they will be instantly ignited.

[0004] (2) Corrosion of equipment by gas: Some explosive gases (such as those containing hydrogen sulfide, chlorine, etc.) are highly corrosive and will accelerate the aging and damage of the metal parts (frame, transmission system) and electrical components (wiring, sensors) of the snowplow, leading to frequent equipment failures, increased maintenance frequency and downtime.

[0005] Currently, conventional snowplows do not employ explosion-proof structures (such as explosion-proof housings, increased safety motors, intrinsically safe control systems, etc.), making it impossible to prevent internal ignition sources from leaking out or external explosive gases from entering the equipment. In the event of an explosion, the equipment itself may disintegrate, and the fragments and shock waves can cause direct injury to the operators. Summary of the Invention

[0006] This application aims to address the current problem that conventional snowplows do not employ explosion-proof structures, making it impossible to prevent internal ignition sources from leaking out or external explosive gases from entering the equipment. Therefore, an explosion-proof snowplow is provided.

[0007] The technical solution of this application is:

[0008] An explosion-proof snowplow comprises a frame body and a snow removal mechanism, the frame body and the snow removal mechanism are connected, and an explosion-proof box is installed on the top of the frame body. The explosion-proof box includes a box body and a steel cover, and the ends of the box body and the steel cover are rotatably connected.

[0009] The steel cover is trapezoidal in shape, and an explosion-proof cover is installed on the side of the steel cover closest to the snow removal mechanism. On the side of the steel cover away from the snow removal mechanism, there are headlight switch sockets, electric lock button sockets and emergency stop button sockets. An explosion-proof instrument mounting plate is provided below the headlight switch sockets, electric lock button sockets and emergency stop button sockets. The instrument mounting plate is connected to the instrument by bolt assembly, and the instrument is installed inside the steel cover.

[0010] The control box and power supply box are installed in the box in a stacked manner, with the power supply box located below the control box. The connectors in the control box are connected to the sockets of the working instruments via wires.

[0011] Furthermore, a shock-absorbing wheel mounting plate, a left gear plate, and a right gear plate are connected to the lower side of the housing away from the snow-clearing mechanism;

[0012] A shock-absorbing wheel mounting plate is installed between the left and right gear plates, and the shock-absorbing wheel mounting plate is installed in the middle of the housing.

[0013] Furthermore, the shock absorber mounting plate is connected to the shock absorber via a bolt assembly, and the left and right gear shift plates are respectively connected to gear shift levers.

[0014] Furthermore, two wheel mounting plates are symmetrically connected to both sides of the box, and a snow removal mechanism docking plate is installed between the two wheel mounting plates. The bottom of the box has a mounting hole for installing a drive motor, and the drive motor is fixed to the bottom of the box by a bolt assembly.

[0015] Furthermore, the box body has round holes on both sides, into which a rotating shaft is inserted. The bottom of the steel cover is connected to an ear plate, and the ear plate at the bottom of the steel cover is connected to the rotating shaft on the box body by a hydraulic rod.

[0016] Furthermore, the explosion-proof cover has symmetrical LED light mounting holes on its left and right sides, and the LED lights are inserted into the explosion-proof cover. The explosion-proof cover and the LED lights are fixedly connected by bolt assemblies.

[0017] Furthermore, a power charging connector is connected to the side of the housing near the snow removal mechanism.

[0018] Furthermore, handrail mounting holes are provided on both sides of the box body, and handrails are installed in the handrail mounting holes by bolt assemblies.

[0019] Compared with the prior art, this application has the following advantages:

[0020] This utility model of an explosion-proof snowplow fully considers explosion-proof requirements in its design, including the installation of an explosion-proof box and explosion-proof cover. The box body is welded from high-performance explosion-proof steel, providing excellent sealing and effectively preventing external flammable and explosive gases from entering the box. This prevents potential explosion hazards such as sparks and static electricity generated during snowplowing operations, ensuring safety when operating in flammable and explosive environments. It also prevents potential sparks from leaking out. The trapezoidal structure of the steel cover not only increases structural strength but also facilitates observation and operation from different angles for the operator.

[0021] This utility model is equipped with a variety of functional components, such as a snow removal mechanism, working instruments, LED lights, and gear adjustment devices, which can meet different snow removal operation needs, including the adjustment of different gears to adapt to different working conditions such as forward, reverse or idling speed, and providing lighting at night or in low light conditions.

[0022] The structural design of this explosion-proof snowplow facilitates maintenance and repair. For example, the steel cover is connected to the box body by a hydraulic rod, which makes it easy to open and repair or replace the internal components. The connection between the various parts is also relatively simple, making it easy to disassemble and install.

[0023] This snowplow can adapt to different working environments and conditions. It can work normally on ordinary roads or in special explosion-proof environments, and can effectively clear different types of snow, such as dry snow and wet snow. Attached Figure Description
