Description

Technical Field

[0001] This invention belongs to the field of aero-engine assembly, and in particular relates to an adjustable engine assembly vehicle. Background Technology

[0002] The manufacturing of aero engines is a highly precision-required process. Aero engines consist of numerous components, and the precision required for the fit between these components is extremely high. This places higher demands on the assembly quality and process control of aero engines. The assembly process of aero engines is affected by many factors. To ensure consistent assembly quality, it is necessary to actively control each stage and influencing factor, and to implement various targeted management and control measures to guarantee assembly quality.

[0003] Patent CN106043366B discloses an engine repair vehicle assembly, which mainly uses guide components and positioning components to reliably position the hydraulic platform vehicle so that the hydraulic platform vehicle will not easily slide. However, it does not solve the problem of vehicle shaking during the assembly vehicle's movement due to deceleration and obstacle avoidance operations, which can easily damage the engine. Summary of the Invention

[0004] The purpose of this invention is to address the problems mentioned in the background section by providing an adjustable engine assembly vehicle.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an adjustable engine assembly vehicle, comprising:

[0006] The main frame is equipped with directional support casters at its bottom.

[0007] A lifting frame, on which a docking assembly for docking an engine is provided;

[0008] An inertial lifting assembly includes a crossbeam fixed to the main frame, a threaded cylinder rotatably connected to the crossbeam, a threaded rod threaded into the threaded cylinder, a lifting frame fixed to the threaded rod, a counterweight slidably fitted on the crossbeam, the counterweight connected to the main frame via a first spring, a rack fixed to the counterweight, and a toothed ring meshing with the rack fixed to the threaded cylinder. When the counterweight slides under inertia, the lifting frame moves downward, thereby lowering the overall center of gravity of the assembled vehicle.

[0009] An anti-slip component is provided at the bottom of the main frame, and a control component for controlling the contact between the anti-slip component and the ground is provided on the crossbeam.

[0010] Furthermore, four guide rods are fixed at the four corners of the bottom of the lifting frame, and all four guide rods slide through the main frame.

[0011] Furthermore, a support plate is fixed at the bottom of the lifting frame, and the lower end of the support plate is connected to a threaded rod via a hydraulic lifting assembly.

[0012] Furthermore, the docking assembly includes a front support frame and a rear support seat that slide on the lifting frame. A toothed rod is fixed on the side of the front support frame and the rear support seat that are close to each other. A gear is rotatably connected to the lifting frame, and both toothed rods mesh with the gear.

[0013] Furthermore, the anti-slip assembly includes two adjustment seats slidably connected to the bottom of the main frame. The two adjustment seats are connected by a second spring. Electromagnets are fixed on the side walls of the two adjustment seats that are close to each other. The two electromagnets are opposite each other with the same pole. An anti-slip plate is provided at the bottom of the main frame. Two support rods are hinged to the upper surface of the anti-slip plate. The upper ends of the two support rods are respectively hinged to the two adjustment seats.

[0014] Furthermore, the control component includes a contact plate fixed to the side wall of the counterweight, and a conductive head matching the contact plate is fixed on the crossbeam. The contact plate is electrically connected to an external power source, and the two electromagnets are electrically connected to the conductive head in parallel through wires. When the contact plate contacts the conductive head, the circuit of the electromagnet is turned on.

[0015] Compared with existing technologies, the advantages of this adjustable engine assembly vehicle are:

[0016] 1. This invention, by setting up an inertial lifting component, allows the counterweight to slide forward due to inertia when the assembly vehicle is decelerating and avoiding obstacles. Through the cooperation of the toothed ring, rack, threaded cylinder, and threaded rod, the lifting frame and engine move downward, thereby lowering the overall center of gravity of the assembly vehicle and improving its stability.

[0017] 2. This invention incorporates an anti-slip component. When the electromagnet is de-energized, the two adjusting seats move closer together, pushing the anti-slip plate down to contact the ground, thus stopping the assembly vehicle, improving vehicle stability, and reducing swaying. Conversely, when the electromagnet is energized, the two adjusting seats move further apart, causing the anti-slip plate to detach from the ground, allowing the assembly vehicle to move normally.

[0018] 3. This invention sets up a control component to control the on / off state of the electromagnet through the contact plate and the conductive head. That is, the on / off state of the electromagnet circuit is controlled by the inertial sliding of the counterweight block. This allows the adjustment of the assembly vehicle's center of gravity and the control of vehicle stability to be carried out simultaneously, without the need for manual adjustment and control by the staff, resulting in a high degree of automation.

[0019] 4. By setting up a docking component, the distance between the front support frame and the rear support seat can be adjusted by rotating the gear. The front support frame supports the intake casing filter mounting side, and the rear support seat fixes the combustion chamber component clamp mounting side, so as to adapt to engines of different models and sizes. The adjustment is convenient and flexible, and the application range is wide. Attached Figure Description

Detailed Implementation

[0026] The following examples are for illustrative purposes only and are not intended to limit the scope of the invention.

[0027] like Figure 1-5 As shown, an adjustable engine assembly vehicle includes:

[0028] Main frame 1, with directional support casters 2 installed at the bottom of the main frame 1;

[0029] The lifting frame 3 is equipped with a docking assembly for docking the engine;

[0030] The inertial lifting assembly includes a crossbeam 4 fixed to the main frame 1, a threaded cylinder 5 rotatably connected to the crossbeam 4, a threaded rod 6 threadedly engaged within the threaded cylinder 5, a lifting frame 3 fixed to the threaded rod 6, a counterweight 7 slidably engaged on the crossbeam 4, the counterweight 7 being connected to the main frame 1 via a first spring 8, a rack 9 fixed to the counterweight 7, and a toothed ring 10 meshing with the rack 9 fixed to the threaded cylinder 5. When the counterweight 7 slides due to inertia, the lifting frame 3 moves downward, thereby lowering the overall center of gravity of the assembly vehicle. When the assembly vehicle is decelerating and avoiding obstacles, the counterweight 7 will slide forward due to inertia. Through the cooperation of the toothed ring 10, rack 9, threaded cylinder 5, and threaded rod 6, the lifting frame 3 and the aircraft engine move downward, thereby lowering the overall center of gravity of the assembly vehicle and improving its stability.

[0031] Anti-slip component, the anti-slip component is set at the bottom of the main frame 1, and a control component is set on the crossbeam 4 to control the contact between the anti-slip component and the ground.

[0032] Four guide rods 11 are fixed at the four corners of the bottom of the lifting frame 3, and the four guide rods 11 slide through the main frame 1.

[0033] The bottom of the lifting frame 3 is fixed with a support plate 12, and the lower end of the support plate 12 is connected to the threaded rod 6 through a hydraulic lifting assembly 13.

[0034] The docking assembly includes a front support frame 14 and a rear support seat 15 that slide on the lifting frame 3. A rack 16 is fixed on the side of the front support frame 14 and the rear support seat 15 that are close to each other. A gear 18 is rotatably connected to the lifting frame 3. Both racks 16 mesh with the gear 18. The gear 18 is rotated by rotating the shaft 17. Since both racks 16 mesh with the gear 18, the distance between the front support frame 14 and the rear support seat 15 can be adjusted. The front support frame 14 supports the intake casing filter mounting side, and the rear support seat 15 fixes the combustion chamber assembly clamp mounting side to adapt to engines of different models and sizes. The adjustment is convenient and flexible, and the applicability is wide.

[0035] The anti-slip assembly includes two adjusting seats 19 slidably connected to the bottom of the main frame 1. The two adjusting seats 19 are connected by a second spring 20. Electromagnets 21 are fixed on the side walls of the two adjusting seats 19 that are close to each other. The two electromagnets 21 are opposite each other with the same pole. An anti-slip plate 22 is provided at the bottom of the main frame 1. Two support rods 23 are hinged to the upper surface of the anti-slip plate 22. The upper ends of the two support rods 23 are respectively hinged to the two adjusting seats 19. When the electromagnets 21 are de-energized, the two adjusting seats 19 move closer to each other, pushing the anti-slip plate 22 down to contact the ground, thereby stopping the assembly vehicle, improving the stability of the vehicle, and reducing shaking.

[0036] The control component includes a contact plate 24 fixed to the side wall of the counterweight 7, and a conductive head 25 matching the contact plate 24 fixed on the crossbeam 4. The contact plate 24 is electrically connected to an external power source. Two electromagnets 21 are electrically connected to the conductive head 25 in parallel through wires. When the contact plate 24 contacts the conductive head 25, the circuit of the electromagnet 21 is turned on. The on and off of the electromagnet 21 is controlled by the contact plate 24 and the conductive head 25. That is, the on and off of the circuit of the electromagnet 21 is controlled by the inertial sliding of the counterweight 7. This allows the adjustment of the center of gravity of the assembly vehicle and the control of vehicle stability to be carried out synchronously and without the need for manual adjustment and control by the staff. The degree of automation is high. When the first spring 8 is in its natural state, the contact plate 24 contacts the conductive head 25. At this time, the anti-slip plate 22 does not contact the ground.

[0037] The working principle of this invention is as follows:

[0038] The height of the lifting frame 3 is adjusted by the hydraulic lifting component 13 to match the height of the engine assembly line. The rotating shaft 17 drives the gear 18 to rotate. Since both racks 16 mesh with the gear 18, the distance between the front support frame 14 and the rear support seat 15 is adjusted. The front support frame 14 supports the intake casing filter mounting side, and the rear support seat 15 fixes the combustion chamber component clamp mounting side to adapt to different engine models and sizes. The adjustment is convenient and flexible, and the applicability is wide.

[0039] When the assembly vehicle is moving, the counterweight 7 will slide forward due to inertia during the deceleration and obstacle avoidance operation. Since the toothed ring 10 is engaged with the rack 9, when the counterweight 7 drives the rack 9 to slide, it drives the toothed ring 10 and the threaded cylinder 5 to rotate. Since the threaded cylinder 5 is threadedly engaged with the threaded rod 6 and the threaded rod 6 cannot rotate, the threaded rod 6 drives the lifting frame 3 to move down, which in turn causes the lifting frame 3 and the aircraft engine to move down, thereby lowering the overall center of gravity of the assembly vehicle and improving its stability.

[0040] When the counterweight 7 slides due to inertia, the contact plate 24 and the conductive head 25 lose contact, causing the electromagnet 21 to be de-energized. Then, under the action of the second spring 20, the two adjusting seats 19 move closer to each other, pushing the anti-slip plate 22 down to contact the ground, thus stopping the assembly vehicle, improving the vehicle's stability, and reducing shaking. After the counterweight 7 is reset under the action of the first spring 8, the contact plate 24 and the conductive head 25 contact each other, energizing the electromagnet 21. Under the action of repulsion, the two adjusting seats 19 move away from each other. After the anti-slip plate 22 is moved up by the support rod 23 and loses contact with the ground, the assembly vehicle can be pushed to move normally.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
