Description

Technical Field

[0001] This utility model relates to the field of airport air conditioning hose retraction vehicle technology, specifically to the guide structure of the airport air conditioning hose retraction vehicle. Background Technology

[0002] When aircraft are parked at an airport, they typically need to use the airport's air conditioning system to supply air to the aircraft in order to meet the cabin air conditioning requirements. The air supply duct is a flexible hose, which needs to be laid from the airport's air conditioning outlet to the cabin air inlet before air supply. After air supply is completed, it is rolled up and stored in a designated location or warehouse using an airport air conditioning hose reel truck.

[0003] Due to the large air volume, the hoses are generally large in diameter and long in length. Therefore, airport air conditioning hose reel trucks are usually used for electric laying and winding of the hoses. Since a small amount of air remains inside the hose after the air supply is finished, it affects the neatness of the winding process. The presence of air can cause the hose to expand locally, forming an "air bulge" phenomenon. During winding, it may result in loose winding, uneven arrangement, or even wrinkles or twists, and the wound volume is large.

[0004] To address the aforementioned issues and facilitate the removal of air from the hose during rewinding, a guide structure for the airport air conditioning hose rewinding vehicle was proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a guide structure for the retraction and deployment of airport air conditioning hoses, which solves the problem of air discharge when the hose is retracted after the air supply ends.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an airport air conditioning hose reeling and unloading vehicle guide structure, including a vehicle body and a reeling assembly and a hose guide assembly integrated on the vehicle body. The hose guide assembly includes a gantry frame, a connecting frame, a front vertical guide roller, a rear vertical guide roller, a front horizontal support roller, an upper horizontal pressure roller, and a lower horizontal support roller. The gantry frame is fixedly installed on the vehicle body. The rear end of the connecting frame is fixedly installed to the frame of the gantry frame. The front vertical guide roller, the rear vertical guide roller, and the front horizontal support roller are integrated on the connecting frame. The upper horizontal pressure roller and the lower horizontal support roller are integrated on the gantry frame, one above the other, along the direction parallel to the front horizontal support roller.

[0007] The upper horizontal pressure roller is mounted on the mounting frame via a nut. The top of the mounting frame is provided with a guide rod and a screw rod in the vertical direction. Both the guide rod and the screw rod are movably installed through the crossbeam of the gantry frame. An elastic clamping assembly is connected to the screw rod. The mounting frame is elastically clamped to the crossbeam of the gantry frame via the elastic clamping assembly. The mounting frame can be elastically raised and lowered along the height direction below the crossbeam of the gantry frame via the elastic clamping assembly. The end of the lower horizontal support roller is detachably installed between the uprights of the gantry frame via a nut. The height of the lower horizontal support roller can be adjusted along the height direction of the uprights of the gantry frame.

[0008] Preferably, the elastic clamping assembly includes a spring sleeved on the screw and two sets of limiting caps threaded onto the screw. The lower limiting cap abuts against the lower end of the spring, the upper end of the spring abuts against the bottom of the crossbeam of the gantry frame, and the upper limiting cap abuts against the top of the crossbeam of the gantry frame and elastically clamps the crossbeam with the spring.

[0009] Preferably, the screw is located in the middle of the gantry frame, and the guide rods are symmetrically distributed on both sides of the screw.

[0010] Preferably, the gantry frame has fixed holes spaced along the height direction, and the end of the lower horizontal roller is detachably installed on the fixed holes by means of two nuts. The lower horizontal roller is installed on the gantry frame at an adjustable height through the fixed holes spaced at intervals.

[0011] Preferably, the front and rear vertical guide rollers are installed on the top of the connecting frame, and the front and rear vertical guide rollers are symmetrically distributed on both sides. The front horizontal support roller is installed at the end of the connecting frame away from the gantry frame, and the height of the front horizontal support roller is close to the position between the installation height of the upper horizontal pressure roller and the lower horizontal support roller.

[0012] This utility model has the following beneficial effects:

[0013] This invention, by setting up a tube guide assembly and mounting frame, helps reduce the resistance of the hose during winding by the front vertical guide roller, rear vertical guide roller, and front horizontal support roller. Correct guidance facilitates the winding operation. The hose is supported by the front horizontal support roller and driven by the winding assembly to pass between the upper horizontal pressure roller and the lower horizontal support roller. The upper horizontal pressure roller and the lower horizontal support roller squeeze out the air in the hose. The height of the upper horizontal pressure roller can be adjusted by the mounting frame to adapt to the air discharge of the hose, making the hose more space-saving, convenient, and neat when winding.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] like Figure 1-5 As shown, this utility model provides a technical solution: an airport air conditioning hose reeling and unloading vehicle guide structure, including a vehicle body 1 and a reeling assembly 2 and a hose guide assembly 3 integrated on the vehicle body 1. The hose guide assembly 3 includes a gantry frame 31, a connecting frame 32, a front vertical guide roller 33, a rear vertical guide roller 34, a front horizontal support roller 35, an upper horizontal pressure roller 36, and a lower horizontal support roller 37. The gantry frame 31 is fixedly installed on the vehicle body 1. The rear end of the connecting frame 32 is fixedly installed on the frame of the gantry frame 31. The front vertical guide roller 33, the rear vertical guide roller 34, and the front horizontal support roller 35 are integrated on the connecting frame 32. The upper horizontal pressure roller 36 and the lower horizontal support roller 37 are integrated on the gantry frame 31 in a direction parallel to the front horizontal support roller 35.

[0022] The front vertical guide roller 33 and the rear vertical guide roller 34 are installed on the top of the connecting frame 32, and the front vertical guide roller 33 and the rear vertical guide roller 34 are symmetrically distributed on both sides. The front horizontal support roller 35 is installed at the end of the connecting frame 32 away from the gantry frame 31, and the height of the front horizontal support roller 35 is close to the position between the installation height of the upper horizontal pressure roller 36 and the lower horizontal support roller 37.

[0023] The upper horizontal pressure roller 36 is mounted on the mounting frame 6 via nuts 4. Guide rods 61 and screws 62 are vertically arranged on the top of the mounting frame 6. Both guide rods 61 and screws 62 are movably installed through the crossbeam of the gantry frame 31. The screws 62 are located in the middle of the gantry frame 31, and the guide rods 61 are symmetrically distributed on both sides of the screws 62. Elastic clamping components 63 are connected to the screws 62. The mounting frame 6 is elastically clamped to the crossbeam of the gantry frame 31 via the elastic clamping components 63. The upper horizontal pressure roller 36 is driven by the elastic clamping assembly 63 to move up and down elastically along the height direction below the crossbeam of the gantry frame 31. The elastic clamping assembly 63 includes a spring 631 sleeved on the screw 62 and two sets of limit caps 632 threaded on the screw 62. The lower limit cap 632 abuts against the lower end of the spring 631, the upper end of the spring 631 abuts against the bottom of the crossbeam of the gantry frame 31, and the upper limit cap 632 abuts against the top of the crossbeam of the gantry frame 31 and elastically clamps the crossbeam with the spring 631.

[0024] The height of the upper horizontal pressure roller 36 is adjusted by the screw 62 and the limit cap 632 on the mounting frame 6. The height of the upper horizontal pressure roller 36 is adjusted to match the height of the lower horizontal support roller 37. During adjustment, only the installation height of the two sets of limit caps 632 on the screw 62 needs to be adjusted. The higher the elastic clamping component 63 is installed on the screw 62, the lower the installation height of the upper horizontal pressure roller 36.

[0025] By setting the elastic clamping component 63, the installation of the upper horizontal pressure roller 36 has a buffering effect. When compressing air, the appropriate spacing and buffering in the natural state can expel air while reducing wear on the hose. Furthermore, the elastic clamping component 63 can raise the upper horizontal pressure roller 36 upward when winding through the hose, increasing the distance between the upper horizontal pressure roller 36 and the lower horizontal support roller 37 to facilitate the passage of the hose.

[0026] The lower horizontal roller 37 is detachably installed between the uprights of the gantry frame 31 via nut 2 5. The lower horizontal roller 37 is installed with adjustable height along the vertical direction via the uprights of the gantry frame 31. Fixing holes 311 are provided at intervals along the vertical direction on the uprights of the gantry frame 31. The lower horizontal roller 37 is detachably installed on the fixing holes 311 via nut 2 5. The lower horizontal roller 37 is installed with adjustable height on the gantry frame 31 via the fixed holes 311 at intervals. The height of the lower horizontal roller 37 is adjusted to match the height of the front horizontal roller 35.

[0027] During winding, the hose is supported by the front cross roller 35 and driven by the winding assembly 2, passing between the upper cross roller 36 and the lower cross roller 37. The upper cross roller 36 and the lower cross roller 37 squeeze out the air in the hose, making the hose more space-saving, convenient and neat when winding.
