Description

Technical Field

[0001] This utility model relates to the field of cleaning vehicle bracket technology, and in particular to a bracket device for cleaning engines of aerospace equipment. Background Technology

[0002] During operation, aircraft engines accumulate contaminants such as oil, dust, and combustion residue, which affect heat dissipation efficiency, increase fuel consumption, and even lead to component corrosion. Therefore, regular cleaning is a critical part of engine maintenance, which can significantly extend service life and ensure flight safety.

[0003] Currently, engine cleaning mainly relies on manual hand-held spray guns or simple support frames. Traditional engine cleaning vehicle brackets mostly use fixed or simple manual adjustment methods, which to some extent limits their adaptability to the cleaning needs of different engine models. When cleaning engines of different sizes and shapes, fixed or manually adjustable brackets are often unsuitable, making it difficult to make precise adjustments to fit the specific contours of the engine. In addition, existing brackets often experience equipment shaking or displacement under the action of high-pressure water flow. When cleaning complex structural parts such as powerful turbines or high-pressure cylinders, these shaking and instability phenomena not only affect cleaning efficiency but may even cause unexpected damage to the engine. Therefore, we propose an engine cleaning vehicle bracket device for aerospace equipment. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies. Traditional engine cleaning vehicle brackets often employ fixed or simple manual adjustment methods, which to some extent limits their adaptability to the cleaning needs of different engine models. When cleaning engines of different sizes and shapes, fixed or manually adjustable brackets are often unsuitable, making it difficult to finely adjust them to fit the specific contours of the engine. Furthermore, existing brackets often experience shaking or displacement under the action of high-pressure water flow. When cleaning complex structural parts such as powerful turbines or high-pressure cylinders, these shaking and instability phenomena not only affect cleaning efficiency but may even cause unexpected damage to the engine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A support device for an aerospace equipment engine cleaning vehicle includes a support device body. A base is provided at the bottom of the support device body, and support columns are symmetrically arranged on both sides of the top of the base. A folding arm is installed at the top of the support column, and a gripper is installed at the top of the folding arm.

[0007] Furthermore, both of the support columns are composed of an outer column and an inner column, with the inner column slidably connected inside the outer column.

[0008] Furthermore, the outer column is fixedly installed on the base. The outer column is hollow, and a motor lead screw is installed on one inner wall of the outer column. A slider is slidably connected to the motor lead screw, and the top of the slider is connected to the inner column.

[0009] Furthermore, a limit plate is provided at the top of the motor lead screw, a horizontal turntable is provided at the top of the inner column, and a folding arm is installed at the top of the horizontal turntable.

[0010] Furthermore, a pitch hinge is provided at the root of the folding arm, a pivot is installed in the middle section of the folding arm, a telescopic rod is installed at the rotating end of the pivot, a ball joint is installed at the end of the telescopic rod, and a gripper is installed on the ball joint.

[0011] Furthermore, a pressure sensor is embedded inside the gripper, and a rubber pad is provided on the gripping surface of the gripper.

[0012] Furthermore, two hinge seats are installed in the middle of the base, and a V-shaped arm is rotatably connected to each hinge seat. Slide grooves are provided on both outer walls of the support column. The end of the V-shaped arm is slidably connected to the slide groove. A snap-fit ​​groove is provided at the top of the slide groove, and the end of the V-shaped arm is snapped into the snap-fit ​​groove.

[0013] Furthermore, auxiliary support rods are rotatably connected to the outer walls on both sides of the two V-shaped arms, with the ends of the auxiliary support rods contacting the ground.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. It adopts a combination structure of electric screw lifting, horizontal turntable and folding arm. The height of the support column can be automatically adjusted, and the folding arm can be adjusted in multiple directions such as pitch, rotation and extension, so that the gripper can accurately fit different curved surfaces of the engine and meet the cleaning needs of various engines such as turbofan, turbojet and turboshaft. In addition, the gripper has a built-in pressure sensor to adaptively control the clamping force, avoid overpressure damage to engine parts, and ensure stable clamping.

[0016] 2. The symmetrical layout of the double support columns, combined with the bottom X-shaped folding truss, forms a stable triangular support, which effectively resists the impact force during high-pressure cleaning and prevents the support from shaking or shifting. The V-shaped arm end can be slidably locked and fixed by the snap-fit ​​groove after unfolding. The secondary support rod enhances the grounding stability and ensures that the equipment does not shift during the cleaning process.

[0017] 3. The support column, folding arm and V-arm all adopt the articulation and slide rail design, which can be folded with one click, reducing the space occupied and making it easy to deploy in narrow cabins or outdoor environments. The electric screw drives the lifting, replacing the traditional manual adjustment, significantly improving work efficiency and reducing the intensity of manual labor. Attached Figure Description

[0027] Example 1

[0028] like Figures 1-4 As shown, this utility model provides a technical solution: a support device for an aerospace equipment engine cleaning vehicle, including a support device body 1, a base 101 at the bottom end of the support device body 1, and support columns 2 symmetrically arranged on both sides of the top end of the base 101. The V-shaped arms 103 of the support columns 2 automatically lock after unfolding to resist the multi-dimensional backlash force during high-pressure cleaning. A folding arm 3 is installed at the top end of the support columns 2. The folding arm 3 can be automatically adjusted and locked without manual intervention, adapting to different engine shapes. At the same time, the ball joint 305 of the folding arm 3 forms a rigid support after locking, solving the swaying problem caused by the flexibility of traditional supports. A gripper 301 is installed at the top end of the folding arm 3.

[0029] Example 2

[0030] like Figures 1-4 As shown, both support columns 2 are composed of an outer column 201 and an inner column 202. The inner column 202 is slidably connected inside the outer column 201. The outer column 201 is fixedly installed on the base 101. The outer column 201 is hollow. A motor lead screw 203 is installed on one inner wall of the outer column 201. A slider 204 is slidably connected to the motor lead screw 203. The top of the slider 204 is connected to the inner column 202. A limit plate 205 is provided at the top of the motor lead screw 203. A horizontal turntable 2 is provided at the top of the inner column 202. 06. A folding arm 3 is installed at the top of the horizontal turntable 206. A pitch hinge 302 is provided at the root of the folding arm 3. A rotating shaft 303 is installed in the middle section of the folding arm 3. A telescopic rod 304 is installed at the rotating end of the rotating shaft 303. A ball joint 305 is installed at the end of the telescopic rod 304. A gripper 301 is installed on the ball joint 305. A pressure sensor is embedded inside the gripper 301. A rubber pad is provided on the gripping surface of the gripper 301. The gripper 301 adaptively clamps different curved surfaces of the engine through feedback control.

[0031] Two hinge seats 102 are installed in the middle of the base 101. Each hinge seat 102 is rotatably connected to a V-shaped arm 103. Slide grooves 207 are provided on both outer walls of the support column 2. The ends of the V-shaped arms 103 are slidably connected to the slide grooves 207. The top of the slide grooves 207 is provided with a snap-fit ​​groove, and the ends of the V-shaped arms 103 are snapped into the snap-fit ​​grooves. When the V-shaped arms 103 are retracted, they are parallel to the base 101. A secondary support rod 104 is rotatably connected to both outer walls of the two V-shaped arms 103. The ends of the secondary support rods 104 are in contact with the ground. The secondary support rods 104 are composed of carbon fiber rods and extend to the ground when unfolded to form a triangular stable support.

[0032] The working process of this utility model is as follows: When using an aerospace equipment engine cleaning vehicle bracket device, firstly, place the bracket device near the engine, unfold the V-shaped arm 103 on the hinge seat 102 on the base 101, so that its end slides along the slide groove 207 of the support column 2 and locks into the locking groove. At the same time, the auxiliary support rod 104 extends to the ground to form a stable triangular support structure to resist the recoil force during high-pressure cleaning. Then, start the motor screw 203 in the support column 2 to drive the inner column 202 to rise and fall to a suitable height, and adjust the horizontal angle of the folding arm 3 through the horizontal turntable 206 so that the gripper 301 is close to the part of the engine to be cleaned.

[0033] The folding arm 3 adjusts the pitch and rotation angles via the pitch hinge 302 and the pivot 303. The telescopic rod 304 controls the extension and retraction distance of the gripper 301. The ball joint 305 enables multi-directional micro-adjustment, ensuring that the gripper 301 accurately fits the engine surface. The gripper 301 adaptively clamps the engine via a built-in pressure sensor. The rubber pad protects the surface from scratches. Locking the ball joint 305 forms a rigid support to prevent shaking during cleaning.

[0034] Connect the high-pressure cleaning equipment, start the cleaning program, and the bracket completes the operation in a stable state. After cleaning, release the gripper 301, fold the arm 3, disengage the V-shaped arm 103 from the locking slot and return it to both sides of the base 101, and retract the auxiliary support rod 104 to complete the device storage.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
