Description

Technical Field

[0001] The utility model relates to the technical field of special equipment for airports, and more specifically, to a ground well joint tray device. Background Art

[0002] Aircraft pipeline refueling trucks are used to refuel aircraft at airports. They are equipped with a ground well connector and a tray for placing the ground well connector. The tray is also equipped with an inductive interlocking device. Existing trays do not have a limiting structure or the limiting structure has poor limiting effect. During the movement of the refueling truck, the ground well connector is at risk of falling, causing damage to the ground well connector and triggering the inductive interlocking device, leading to emergency braking of the vehicle, which also poses the risk of rear-end collisions or personal injuries. Furthermore, when the tray is equipped with a limiting structure, the ground well connector is blocked by the limiting structure and needs to be lifted from the tray before it can be removed. However, the ground well connector is heavy overall, making it difficult to lift. There is also a risk of it falling if not handled with care, posing a safety risk. Utility Model Content

[0003] In order to overcome the defects of the above-mentioned prior art in that the ground well joint is blocked by the limiting structure and needs to be lifted from the tray before being removed during use, which is laborious and unsafe, the utility model provides a ground well joint tray device, which makes it unnecessary to lift the ground well joint when removing it, thus saving effort.

[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is: a ground well joint tray device, including: a lifting device, a tray installed on the lifting end of the lifting device, and a movable limiting member movably connected to the tray, and the top of the movable limiting member is higher and lower than the placement surface of the tray when it is raised and lowered.

[0005] The lifting device is used to drive the tray and the ground well connector to descend. Existing refueling trucks are generally equipped with this type of lifting device. The movable limiter is used to limit the ground well connector when the ground well connector is placed on the tray. This can fully ensure the limiting effect and prevent the ground well connector from falling during the movement of the refueling truck. The movable limiter is set to be movably connected to the tray. When it is raised, the top of the movable limiter is higher than the placement surface of the tray, thereby limiting the ground well connector. When it is lowered, the top of the movable limiter is lower than the placement surface of the tray. The placement surface of the tray is the surface used to place the ground well connector, thereby avoiding the ground well connector. When the ground well connector needs to be removed, the ground well connector can be directly dragged out without having to lift it, saving effort. The existing ground well connector has rollers at the bottom. When the lifting device lowers the ground well connector with the ground well connector and the rollers of the ground well connector touch the ground or are about to touch the ground, the ground well connector is directly dragged out and then the rollers fall to the ground, avoiding the risk of the ground well connector falling due to the need to lift it, avoiding damage to the ground well connector, and avoiding danger. The placement surface of the tray is the surface for placing the ground well joint. Specifically, the movable stopper can be movably connected to the tray by vertical sliding connection or rotation connection, and the structure for driving the movable stopper to rise or fall can be manually driven or electrically driven, without limitation.

[0006] Preferably, a limiting member is further included, wherein the movable limiting member includes a mounting portion movably connected to the tray, a limiting portion and a connecting portion respectively connected to both ends of the mounting portion, and the limiting member abuts against the connecting portion and keeps the limiting portion in a raised state.

[0007] The mounting portion is vertically slidably connected or rotatably connected to the tray to form a movable connection. The limiting portion is used to limit the ground well joint, and the connecting portion is used to abut against the limiting member to keep the limiting portion in a raised state.

[0008] Preferably, the mounting portion is rotatably connected to the tray, and the limiting member is located above the connecting portion.

[0009] The mounting portion is movably connected to the tray by a rotational connection, and the rotation is smoother than the vertical sliding, thereby improving the smoothness of the movement of the mounting portion.

[0010] Preferably, the limiting member is relatively fixed to a fixed end of the lifting device, and when the lifting device drives the movable limiting member to rise, the limiting member abuts against the connecting portion to cause the limiting portion to rotate.

[0011] The limiting part blocks the connecting part. When the movable limiting part is raised along with the lifting device, the limiting part blocks the connecting part, so that the movable limiting part rotates while being raised, thereby causing the limiting part to rise and limit the ground well joint. Specifically, the limiting part and the connecting part form a seesaw structure relative to each other. When the connecting part descends, the limiting part is tilted. After the lifting device is completed, the limiting part always presses against the connecting part, thereby causing the limiting part to limit the ground well joint during driving. At the same time, the limiting part uses the power of the lifting device to indirectly drive the movable limiting part to rotate, eliminating the need for an additional power structure, making full use of the existing structure for driving, and lowering the cost.

[0012] Preferably, the connection position between the mounting portion and the tray is located in the middle of the mounting portion, and the limiting portion is heavier than the connecting portion.

[0013] When the movable limit part is raised, the connecting part is blocked by the limiting part and thus drives the limiting part to rise. The limiting part is set to be heavier than the connecting part, so that when the movable limit part descends, one end of the limiting part can rotate downward under the action of gravity. At this time, the connecting part will be tilted up, and after the limit part rotates downward, the top of the limit part itself will be lower than the placement surface of the tray, so that the ground well joint can be directly dragged out, and then gravity is used to drive the movable limit part to rotate, further saving costs.

[0014] Preferably, it further comprises a driving member having two ends connected to the tray and the mounting portion respectively, wherein the driving member drives the mounting portion to rotate, thereby driving the limiting portion to rotate downward.

[0015] When the weight of one end of the limiting part is not convenient to be set greater than that of the connecting part, or when rotation by gravity is prone to jamming, a driving part is added to further increase the power of the movable limiting part to rotate downward and ensure smooth rotation.

[0016] Preferably, the driving member is a spring.

[0017] The use of a spring in the drive element allows the elastic force to be used as the driving force, eliminating the need for an additional power structure and further reducing costs. Either a compression spring or a tension spring can be used to drive the movable stopper to rotate.

[0018] Preferably, the driving member is a tension spring.

[0019] The effect of using a tension spring for rotational drive is better. Specifically, the two ends of the tension spring are respectively connected to the tray and the mounting part, and pass around the rotating part of the mounting part. The middle part of the tension spring abuts against the rotating part, so that the mounting part can rotate around the rotating part.

[0020] Preferably, the mounting portion is provided at the bottom of the tray.

[0021] The installation part is arranged at the bottom of the tray to save space.

[0022] Preferably, the limiting portion is an arc-shaped plate.

[0023] The limiting portion is set as an arc-shaped plate to increase the limiting area of ​​the limiting portion, thereby preventing the ground well joint from being scratched by the limiting portion and also increasing the limiting effect.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] When the movable limiter is raised, the ground well joint is limited to ensure the limiting effect and prevent the ground well joint from falling. When the movable limiter is lowered, the ground well joint is avoided so that the ground well joint can be directly dragged out and then separated from the tray. There is no need to lift the ground well joint during the process, which is more labor-saving, safer and more convenient to operate. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0035] Example 1

[0036] like Figure 1-3 and Figure 5 As shown, a ground well joint tray device includes: a lifting device 1, a tray 2 installed on the lifting end of the lifting device 1, and a movable limiting member 3 movably connected to the tray 2. When the movable limiting member 3 is raised and lowered, the top is higher and lower than the placement surface of the tray 2 respectively.

[0037] The lifting device 1 is used to drive the tray 2 and the ground well connector 6 to descend. Existing refueling trucks are generally equipped with this type of lifting device 1. The movable limiting member 3 is used to limit the ground well connector 6 when the ground well connector 6 is placed on the tray 2, which can fully ensure the limiting effect and prevent the ground well connector 6 from falling during the movement of the refueling truck; the movable limiting member 3 is set to be movably connected with the tray 2. When raised, the top of the movable limiting member 3 is higher than the placement surface of the tray 2, thereby limiting the ground well connector 6. When lowered, the top of the movable limiting member 3 is lower than the placement surface of the tray 2. The placement surface of the tray 2 is the surface for placing the ground well connector 6, thereby avoiding the ground well connector 6. When the ground well connector 6 needs to be removed, the ground well connector 6 can be directly dragged out without having to lift it, saving effort. The existing ground-well connector 6 is provided with rollers at the bottom. When the lifting device 1 lowers the ground-well connector 6 with the rollers thereof touching the ground or about to touch the ground, the ground-well connector 6 is directly dragged out and then the rollers fall to the ground, thereby avoiding the risk of the ground-well connector 6 falling due to the need to lift it up, avoiding damage to the ground-well connector 6, and avoiding danger. The placement surface of the tray 2 is the surface for placing the ground-well connector 6. Specifically, the movable limit member 3 can be movably connected to the tray 2 by means of a vertical sliding connection or a rotational connection, and the structure for driving the movable limit member 3 to rise or fall can be manually driven or electrically driven, and there is no limitation here.

[0038] The beneficial effects of this embodiment are as follows: when the movable limiting member 3 is raised, the ground well connector 6 is limited to ensure the limiting effect and prevent the ground well connector 6 from falling; when the movable limiting member 3 is lowered, it avoids the ground well connector 6 so that the ground well connector 6 can be directly dragged out and then separated from the tray 2. The process does not require lifting the ground well connector 6, which is more labor-saving, safer and more convenient to operate.

[0039] Example 2

[0040] like Figure 1-5 As shown, based on Example 1, the difference from Example 1 is:

[0041] It also includes a limiting member 4. The movable limiting member 3 includes a mounting portion 301 movably connected to the tray 2, a limiting portion 302 and a connecting portion 303 respectively connected to both ends of the mounting portion 301. The limiting member 4 abuts against the connecting portion 303 and keeps the limiting portion 302 in a raised state. The mounting portion 301 is rotatably connected to the tray 2, and the limiting member 4 is located above the connecting portion 303. The limiting member 4 is relatively fixed to the fixed end of the lifting device 1. When the lifting device 1 drives the movable limiting member 3 to rise, the limiting member 4 abuts against the connecting portion 303 and thus rotates the limiting portion 302. The connection position between the mounting portion 301 and the tray 2 is located in the middle of the mounting portion 301, and the weight of the limiting portion 302 is greater than that of the connecting portion 303.

[0042] The mounting portion 301 is connected to the tray 2 by vertical sliding or rotational connection, thereby achieving a movable connection. The limiting portion 302 is used to limit the ground well joint 6, and the connecting portion 303 is used to abut against the limiting member 4 to maintain the limiting portion 302 in the raised state. The mounting portion 301 is connected to the tray 2 by rotational connection. Rotation is smoother than vertical sliding, thereby improving the smoothness of the movement of the mounting portion 301. The limiting member 4 blocks the connecting portion 303. When the movable limiting member 3 is lifted along with the lifting device 1, the limiting member 4 blocks the connecting portion 303, causing the movable limiting member 3 to rotate while being lifted, thereby causing the limiting portion 302 to be lifted and limit the ground well joint 6. Specifically, the limiting portion 302 and the connecting portion 303 form a seesaw structure relative to each other. When the connecting portion 303 descends, the limiting portion 302 is tilted. After the lifting device 1 is completely lifted, the limiting member 4 always presses against the connecting portion 303, thereby causing the limiting portion 302 to limit the ground well joint 6 during driving. At the same time, the limiting member 4 uses the power of the lifting device 1 to indirectly drive the movable limiting member 3 to rotate, eliminating the need for an additional power structure, making full use of the existing structure for driving, and lowering the cost. When the movable limit member 3 is raised, the connecting part 303 is blocked by the limiting member 4 and thus drives the limiting part 302 to rise. The limiting part 302 is set to be heavier than the connecting part 303, so that when the movable limit member 3 descends, one end of the limiting part 302 can rotate downward under the action of gravity. At this time, the connecting part 303 will be tilted up. After the limiting part 302 rotates downward, the top of the limiting part 302 itself is lower than the placement surface of the tray 2, so that the ground well connector 6 can be directly dragged out, and then the movable limit member 3 is driven to rotate by gravity, which further saves costs.

[0043] Furthermore, in this embodiment, the limiting member 4 is the vehicle body or an existing structure on the vehicle body.

[0044] The remaining features and working principles of this embodiment are consistent with those of embodiment 1.

[0045] Example 3

[0046] like Figure 1-5 As shown, based on Example 1 or Example 2, Example 1 or Example 2 is further limited, and the difference is that:

[0047] The device also includes a driving member 5, with its ends connected to the tray 2 and the mounting portion 301, respectively. The driving member 5 drives the mounting portion 301 to rotate, thereby driving the limiting portion 302 to rotate downward. The driving member 5 is a spring. The driving member 5 is a tension spring. The mounting portion 301 is located at the bottom of the tray 2. The limiting portion 302 is a curved plate.

[0048] When the weight of one end of the limiting part 302 is not convenient to be set larger than that of the other end of the connecting part 303, or when the rotation relying on gravity is prone to jamming, a driving member 5 is added to further increase the power of the movable limiting part 3 to rotate downward and ensure smooth rotation. The driving member 5 uses a spring and can use elastic force as the driving force, eliminating the need for an additional power structure. This further reduces costs. Either a compression spring or a tension spring can be used to drive the movable limiting part 3 to rotate. The effect of using a tension spring is better when rotating. Specifically, Figure 4 As shown, the ends of the tension spring are connected to the tray 2 and the mounting portion 301, respectively. The tension spring passes around the rotating portion of the mounting portion 301, with the middle portion of the tension spring abutting against the rotating portion, allowing the mounting portion 301 to rotate around the rotating portion. Placing the mounting portion 301 at the bottom of the tray 2 saves space. Designing the limiting portion 302 as an arc-shaped plate increases the limiting area of ​​the limiting portion 302, preventing the ground-well connector 6 from being scratched by the limiting portion 302 and enhancing the limiting effect.

[0049] In this embodiment, Figure 3 As shown, the limiting member 4 is an original structure on the vehicle body and is a part of the vehicle body, and the lifting device 1 is arranged on one side of the limiting member 4, the fixed end of the lifting device 1 is fixedly connected to the limiting member 4, and the lifting end of the lifting device 1 is connected to the pallet 2 through an L-shaped connecting rod.

[0050] In this embodiment, Figure 3 As shown, a side of the tray 2 close to the limiting member 4 is provided with an arc-shaped limiting plate fixedly connected to the tray 2 , and the limiting portion 302 is provided opposite to the limiting plate, that is, on the side away from the limiting member 4 .

[0051] The rest of the working principle and working process of this embodiment are consistent with those of embodiment 1 or embodiment 2.

[0052] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here.
