Description

Technical Field

[0001] This utility model relates to the field of de-icing vehicle technology, and in particular to a support structure for the operating cabin of a de-icing vehicle. Background Technology

[0002] During flight or parking, aircraft surfaces can ice up due to impacts from supercooled water droplets in the air, especially on critical areas such as the leading edge of the wings, tail, propeller, engine air intakes, and pitot tubes. Icing disrupts the aircraft's aerodynamic shape, leading to decreased lift, increased drag, and even control surface jamming or instrument data distortion, seriously threatening flight safety. According to aviation safety statistics, over 60% of flight accidents caused by icing are directly related to deterioration of wing or tail performance. For example, icing can increase stall speed by more than 15%, significantly increasing the risks during takeoff, cruise, and landing. Therefore, timely de-icing of aircraft in low-temperature, high-humidity environments is a necessary measure to ensure aviation safety.

[0003] De-icing trucks are one of the core pieces of equipment for airport ground support. They achieve efficient de-icing operations by integrating heating systems, fluid delivery devices, and telescopic booms. A typical de-icing truck uses an onboard boiler to heat anti-icing fluid (such as ethylene glycol-based solutions) to 80°C-90°C, which is then delivered to the spray boom via a high-pressure pump. Multiple nozzles form a fan-shaped atomization band that evenly covers the aircraft surface.

[0004] The front of the de-icing truck is equipped with an operator cabin, which is driven by an operator. De-icing fluid and antifreeze are sprayed through a spray gun at the front of the operator cabin. Currently, the rear of the operator cabin is usually connected to the vehicle's connecting arm. When the operator enters the operator cabin, the center of gravity of the operator cabin shifts forward relative to the connection position, resulting in poor connection stability. Furthermore, the connection structure is more prone to damage during long-term use. Utility Model Content

[0005] This application provides a support structure for the operating cabin of a de-icing truck. By positioning the connection between the vehicle and the operating cabin below the operating cabin, the center of gravity of the operating cabin is located in the space above and near the connection structure, thus solving the technical problems of instability of the operating cabin's center of gravity and susceptibility to damage caused by the original connection structure. This application also provides a de-icing truck, including the de-icing truck operating cabin support structure.

[0006] The first aspect of this application provides a support structure for the operating compartment of a de-icing vehicle, including:

[0007] Base, connected to the vehicle body;

[0008] The first arm is hinged to the base at its rear end;

[0009] A first driving component is disposed between the first support arm and the vehicle body;

[0010] The second arm is hinged at its upper end to the front end of the first arm;

[0011] The second driving component is disposed between the first arm and the second arm;

[0012] The third arm is hinged to the lower end of the second arm;

[0013] The fourth arm is hinged to the other side of the third arm relative to the second arm;

[0014] The third driving component is disposed between the third arm and the fourth arm;

[0015] A slewing drive device is installed on the fourth support arm. The lower rear end of the operating cabin has a recessed structure, which is located directly below the operating cabin. The slewing drive device is connected to the recessed structure.

[0016] The beneficial effects of the above embodiments are as follows: the operation cabin can be raised and lowered and its tilt angle adjusted by the cooperation of the first, second, third and fourth support arms. By setting the rotary drive device directly below the seat of the operation cabin, the center of gravity of the operator is closer to the top of the rotary drive device after entering the operation cabin, which improves the stability of the operation cabin when it moves. The connection structure is subjected to less force and the force is more reasonable, which makes it easier to use the connection structure stably for a long time. In addition, the addition of the rotary drive device allows the operation cabin to rotate in the plane, which increases the spraying space of the nozzles on the front side of the operation cabin.

[0017] Based on the above embodiments, the embodiments of this application can be further improved as follows:

[0018] In one embodiment of this application, a counterweight plate is provided on the side of the base opposite to the first driving member. The beneficial effect of this step is that the counterweight plate balances the center of gravity of the overall structure, thereby reducing the structural stress at the connection between the base and the vehicle body structure.

[0019] In one embodiment of this application: the lower end of the middle portion of the first support arm has a support rod, and the vehicle body is equipped with a positioning seat corresponding to the support rod, the support rod being inserted into the positioning seat. The beneficial effect of this step is that the cooperation between the support rod and the positioning seat improves the stability of the first support arm after it is folded onto the vehicle body.

[0020] In one embodiment of this application, it further includes a support roller, which is mounted on the front end of the vehicle and is used to contact the rear side of the second support arm. The beneficial effect of this step is that the support roller supports the second support arm folded to the front end of the vehicle, thereby improving the stability of the second support arm's positioning.

[0021] In one embodiment of this application, the system further includes: hooks and connectors. The hooks are mounted on both sides of the support roller, and the connectors are used to connect the hooks to the second support arm. The beneficial effect of this step is to further improve the stability of the second support arm's positioning.

[0022] In one embodiment of this application, the system further includes a guide roller mounted on the lower end of the fourth support arm. The guide roller supports the pipe connected to the operating cabin. The beneficial effect of this step is that by supporting the pipe with the guide roller, the stability of the pipe's positioning is improved, thereby improving the stability of the operating cabin's positioning.

[0023] In one embodiment of this application: the third arm is provided with a limiting hole, and the fourth arm has a limiting structure, the limiting structure being slidably inserted into the limiting hole, the limiting hole being used to limit the rotation angle of the fourth arm. The beneficial effect of this step: by limiting the rotation angle of the fourth arm through the limiting hole, the pitch angle of the operating cabin is limited.

[0024] In one embodiment of this application: a de-icing vehicle includes the aforementioned de-icing vehicle operation cabin support structure. Attached Figure Description

[0033] In this application, the direction of the front of the vehicle is forward, and the direction of the rear of the vehicle is backward.

[0034] Example 1

[0035] like Figure 1-4 As shown, a support structure for the operating compartment of a de-icing truck includes: a base 1, a first support arm 2, a first drive member 3, a second support arm 4, a second drive member 5, a third support arm 6, a fourth support arm 7, a third drive member 8, and a rotary drive device 9. The base 1 is connected to the vehicle body. The rear end of the first support arm 2 is hinged to the base 1. The first drive member 3 is disposed between the first support arm 2 and the vehicle body. The upper end of the second support arm 4 is hinged to the front end of the first support arm 2. The second drive member 5 is disposed between the first support arm 2 and the second support arm 4. Between the two arms, the third arm 6 is hinged to the lower end of the second arm 4, the fourth arm 7 is hinged to the other side of the third arm 6 relative to the second arm 4, the third drive member 8 is disposed between the third arm 6 and the fourth arm 7, the rotary drive device 9 is installed on the fourth arm 7, the lower rear end of the operating cabin 10 has a recess structure 1001, the recess structure 1001 is located directly below the operating cabin 10, and the rotary drive device 9 is connected to the recess structure 1001.

[0036] In some embodiments of this application, the first driving member 3, the second driving member 5, and the third driving member 8 are all hydraulic cylinders. In addition, devices with linear drive functions, such as electro-hydraulic actuators and electric actuators, can also be used.

[0037] In some embodiments of this application, such as Figure 1As shown, when the first support arm 2 is folded to the top of the vehicle body and the second support arm 4 is folded to the front of the vehicle body, the front end of the base 1 is bolted to the slewing mechanism configured on the vehicle body. The rear end of the first support arm 2 is hinged to the rear end of the base 1. The rear end of the first drive member 3 is hinged to the base 1 and the hinge position is located on the rear side of the slewing mechanism. The front end of the first drive member 3 is hinged to the lower middle part of the first support arm 2 and the hinge position is located on the front side of the slewing mechanism.

[0038] In some embodiments of this application, such as Figure 1 As shown, a counterweight plate 101 is provided on the other side of the base 1 relative to the first driving member 3. The counterweight plate 101 is located on both sides of the rear end of the base 1 and forms a symmetrical structure. The counterweight plate 101 balances the center of gravity of the overall structure, thereby reducing the force at the connection between the base 1 and the vehicle body structure, thereby improving the stability of the connection structure and extending the service life of the connection structure.

[0039] In some embodiments of this application, such as Figure 1 As shown, the lower end of the middle part of the first support arm 2 has a support rod 201, and the vehicle body is equipped with a positioning seat corresponding to the support rod 201. The support rod 201 is used to be inserted into the positioning seat. The lower end of the support rod 201 is a V-shaped structure with the tip facing down. The upper end of the positioning seat has a positioning groove with a V-shaped structure. The first support arm 2 is stably positioned by the self-centering property of the V-shaped structure.

[0040] In some embodiments of this application, such as Figure 4 As shown, the second arm 4 and the third arm 6 cooperate to form a parallelogram linkage mechanism. Taking the second arm 4 folded to the front of the vehicle as a reference direction, the second arm 4 has a first rod 401 and a second rod 402. There are two first rods 401 and one second rod 402. The first rods 401 are symmetrically arranged on the left and right sides of the front end of the first arm 2 and are hinged to the first arm 2 at their upper ends. The second rod 402 is located at the front side of the middle of the first rod 401 and is hinged to the first arm 2 at its upper end. The first arm 2 and the second arm 4 are parallel to each other. The distance between the hinged positions of the two ends of the first rod 401 is the same as the distance between the hinged positions of the two ends of the second rod 402. The distance between the upper hinge points of the first rod 401 and the second rod 402 is the same as the distance between the lower hinge points of the first rod 401 and the second rod 402. Thus, the first rod 401 and the second rod 402 form two symmetrical parallelogram structures on both sides of the first arm 2 and the third arm 6.

[0041] In some embodiments of this application, such as Figure 3As shown, the de-icing truck operating cabin support structure also includes: a support plate 11 and a support roller 12. The support plate 11 is installed on the front side of the truck head, and the support roller 12 is rotatably installed on the front side of the support plate 11. The support roller 12 is used to contact the rear side of the second support arm 4. The second support arm 4, which is folded to the front of the truck head, is supported by the support roller 12, thereby improving the stability of the positioning of the second support arm 4.

[0042] In some embodiments of this application, the de-icing truck operating cabin support structure further includes: hooks and connectors. The hooks are installed on both sides of the support plate 11, and the connectors are used to connect the hooks to the second support arm 4. The connectors can be products such as ropes or straps, with the purpose of securing the second support arm 4 to the hooks, thereby improving the stability of the overall structural positioning.

[0043] In some embodiments of this application, such as Figure 3 As shown, the de-icing truck operating cabin support structure also includes: a bracket 13 and guide rollers 14. The bracket 13 is installed at the lower middle part of the fourth support arm 7. The bracket 13 has two spaced guide rollers 14 in the height direction. A pipe (such as a liquid supply pipe for a nozzle) connected to the operating cabin 10 is inserted between the guide rollers 14. The guide rollers 14 support the pipe, improving the stability of the pipe positioning, thereby improving the stability of the operating cabin 10 positioning.

[0044] In some embodiments of this application, such as Figure 3 As shown, the third arm 6 is equipped with a limiting hole 601, and the fourth arm 7 has a limiting structure. The limiting structure is slidably inserted into the limiting hole 601, which is used to limit the rotation angle of the third arm 6. Specifically, the limiting hole 601 is an arc-shaped structure surrounding the hinge point between the fourth arm 7 and the third arm 6. The upper end of the third drive member 8 is hinged to the upper end of the third arm 6, the rear end of the fourth arm 7 is hinged to the lower end of the third drive member 8, and the rear middle part of the fourth arm 7 is also hinged to the third arm 6. The limiting structure is a protruding structure on the side of the third arm 6. By limiting the rotation angle of the fourth arm 7 through the limiting hole 601, the pitch angle of the operating cabin 10 is limited.

[0045] In some embodiments of this application, the rotary drive device 9 is a worm gear rotary reducer, which is an existing product and can be directly purchased.

[0046] The operation cabin 10 can be raised, lowered, and tilted by the cooperation of the first arm 2, the second arm 4, the third arm 6, and the fourth arm 7. By setting the slewing mechanism directly below the seat of the operation cabin 10, the center of gravity of the operator is closer to the top of the slewing mechanism after entering the operation cabin 10, which improves the stability of the operation cabin 10 during operation. The connection structure is subjected to less force and the force is more reasonable, which is conducive to the long-term stable use of the connection structure. In addition, the addition of the slewing mechanism allows the operation cabin 10 to rotate in the plane, which increases the spraying space of the front nozzle of the operation cabin 10.
