Description

Technical Field

[0001] This utility model relates to the technical field of turbine pump assembly auxiliary equipment, specifically to an anti-tipping assembly tilting vehicle for turbine pump disassembly. Background Technology

[0002] As a core component of critical power systems such as aerospace engines and liquid rocket engines, the assembly quality of turbopumps directly affects the overall performance and reliability of the system. During turbopump assembly, precise positioning, stable rotation, and multi-angle assembly and attitude adjustment of components such as the pump housing, nut adapters, and nut assemblies are required. Therefore, a tilting vehicle becomes an indispensable auxiliary equipment in turbopump assembly operations. Its main function is to support the turbopump housing and enable safe rotation in multiple positions in space, facilitating the fixing, inspection, and adjustment of internal parts by assembly personnel.

[0003] Existing tilting machines typically achieve the holding and tilting of the turbine pump housing through a tilting frame, support mechanism, and locking mechanism. Some tilting machines are also equipped with interchangeable tooling interfaces to accommodate different pump models. However, the structure of these tilting machines is mostly designed for conventional specifications and torque components, and their stability and adaptability are significantly limited.

[0004] When assembling nut adapters, the adapters themselves experience significant stress and a noticeable shift in their center of gravity. Existing tilting machines often only have a simple tilting function and lack reliable lateral support design. Especially during the tilting process, if the force is concentrated at the eccentric position, the nut adapter is prone to slight tilting or even tipping over due to excessive lateral torque, affecting assembly safety. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-tipping assembly tilting vehicle for disassembling turbine pumps, which solves the problem that the nut adapter in the prior art is prone to slight tilting or even tipping over due to excessive lateral torque.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: An anti-rollover assembly rollover vehicle for turbine pump disassembly includes: Assembly vehicle body; The cradle, rotatably connected to the assembly vehicle body via a pivot, is used to house the turbine pump and enable its tilting. A flipping drive device, connected to the rotating shaft, is used to drive the cradle to flip. A locking device is used to lock the cradle after it has been flipped to a predetermined position; A lifting system includes a drive component, a transmission mechanism, and at least two lifting platforms; the drive component synchronously drives each of the lifting platforms through the transmission mechanism. A lifting platform is rigidly connected to the top of each of the aforementioned lifting machines and is used to maintain a horizontal state during the lifting process; The lifting platform is equipped with a connection structure for rigidly fixing the torque multiplier housing, so that the working plane of the torque multiplier is constrained by the lifting platform when torque is applied, thereby preventing the nut adapter connected to the torque multiplier from tipping over.

[0007] A further technical solution is that the connection structure includes a connection groove and two connection holes; the two connection holes are respectively located at both ends of the connection groove.

[0008] A further technical solution is that the lifting platform is provided with a lifting point structure for disassembling the turbine pump housing; each lifting point structure includes a lifting eye screw and multiple threaded holes; the multiple threaded holes are evenly arranged at both ends of the connecting groove and located on the side of the connecting hole away from the connecting groove; the number of lifting eye screws is more than one, and they are detachably provided on any of the threaded holes and located below the lifting platform.

[0009] A further technical solution is that the cradle has multiple connecting holes arranged in a circular array; the connecting holes are detachably provided with adapter blocks; the adapter blocks have clamping holes arranged radially along the cradle; and clamping screws are slidably connected to the clamping holes.

[0010] A further technical solution is that the lifting platform is H-shaped.

[0011] A further technical solution is that the lifting platform has multiple weight-reducing holes.

[0012] A further technical solution is that the assembly vehicle body includes a floor plate; the number of the lifting platforms is four, and they are distributed at the four corners of the floor plate; each lifting platform includes a lifting platform body and a vertically arranged lead screw; the lifting platform is threadedly connected to the lead screw.

[0013] A further technical solution is that the transmission mechanism includes two transmission shafts and three horizontal shafts; the driving component is disposed on the base plate and located between two of the elevator bodies; the three horizontal shafts are respectively connected to adjacent elevator bodies; the driving component is connected to the remaining two adjacent elevator bodies through the two transmission shafts.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This application employs a bottom-supported stable support structure composed of a lifting platform and a lifting system. When a torque multiplier is used on the lifting platform and torque is applied, its reaction force is directly transmitted to the lifting platform and borne by multiple lifting points, forming a stable and uniform support structure, which greatly improves the system's anti-tipping capability. At the same time, because the lifting platform confines the working plane of the torque multiplier within a stable constraint plane, the nut adapter connected to it will not deflect, tilt, or tip over, eliminating the lateral instability problem of the nut adapter caused by high torque operation from the source.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Example: like Figures 1-2 As shown, this utility model provides an assembly tilting vehicle for disassembling a turbopump to prevent tipping, including an assembly vehicle body 1, a cradle 2, a tilting drive device 3, a locking device 4, a lifting system 5, and a lifting platform 6; the cradle 2 is rotatably connected to the assembly vehicle body 1 via a rotating shaft, and is used to place the turbopump and achieve tilting; the tilting drive device 3 is connected to the rotating shaft and is used to drive the cradle 2 to tilt; the locking device 4 is used to lock the cradle 2 after it has tilted to a predetermined position; The lifting system 5 includes a drive unit 51, a transmission mechanism 52, and at least two lifting platforms 53; the drive unit 51 synchronously drives each lifting platform 53 through the transmission mechanism 52; the lifting platform 6 is rigidly connected to the top of each lifting platform 53 to maintain a horizontal state during the lifting process; wherein, the lifting platform 6 is provided with a connection structure for rigidly fixing the torque multiplier housing, so that the working plane of the torque multiplier when torque is applied is constrained by the lifting platform 6, thereby preventing the nut adapter connected to the torque multiplier from overturning.

[0020] The principles and beneficial effects of the above technical solution: This application employs a bottom-supported stable support structure formed by the lifting platform 6 and the lifting system 5. When a torque multiplier is used on the lifting platform 6 and torque is applied, its reaction force is directly transmitted to the lifting platform 6 and borne by the multi-point lifting mechanism 53, forming a stable and uniform support structure, which greatly improves the system's anti-tipping capability. At the same time, because the lifting platform 6 confines the working plane of the torque multiplier within a stable constraint plane, the nut adapter connected to it will not deflect, tilt, or tip over, eliminating the lateral instability problem of the nut adapter caused by high torque operation from the source.

[0021] In this embodiment, the connection structure includes a connection groove 61 and two connection holes 62; the two connection holes 21 are located at both ends of the connection groove 61.

[0022] The principles and beneficial effects of the above technical solution: The connecting groove 61 and the connecting holes 21 at both ends form a multi-point fixing interface, which can provide lateral and longitudinal bidirectional limiting constraints on the torque multiplier housing, preventing relative slippage, swaying, or rotation when torque is applied. Simultaneously, this structure is rigidly connected to the lifting platform 6, allowing the torque reaction force to be quickly distributed throughout the platform and to the multiple lifting machines 53, improving overall stress stability. This further enhances the anti-tipping capability of the nut adapter under high torque.

[0023] In this embodiment, the lifting platform 6 is provided with a lifting point structure for disassembling the turbine pump housing; each lifting point structure includes a lifting eye screw 63 and multiple threaded holes 64; the multiple threaded holes 64 are evenly arranged at both ends of the connecting groove 61 and are located on the side of the connecting hole 21 away from the connecting groove 61; the number of lifting eye screws 63 is more than one, and the threaded connection is provided on any threaded hole 64 and located below the lifting platform 6.

[0024] The principles and beneficial effects of the above technical solution: The lifting point structure uses multiple evenly arranged threaded holes 64 to allow the eye bolts 63 to be connected to the threaded holes 64 at different positions, enabling the lifting of turbine pump housings of different diameters.

[0025] In this embodiment, the cradle 2 has a plurality of connecting holes 21 arranged in a circular array; the connecting holes 21 are detachably provided with adapter blocks 7 by bolts; the adapter blocks 7 have abutting holes arranged radially along the cradle 2; and abutting screws 71 are slidably connected to the abutting holes.

[0026] The principles and beneficial effects of the above technical solution: The turbine pump housing is secured by passing the clamping screw 71 through the clamping hole and threading it into the pre-drilled threaded hole on the turbine pump housing.

[0027] In this embodiment, the lifting platform 6 is H-shaped.

[0028] The principles and beneficial effects of the above technical solution: The H-shaped structure possesses excellent bending stiffness, torsional stiffness, and multi-directional support capabilities. When subjected to high torque reaction forces, the H-shaped structure effectively suppresses torsional deformation of the platform, maintaining planar rigidity even under high loads. This structure further enhances the aforementioned ability to constrain the applied force plane, enabling the torque multiplier to maintain a stable working posture under any operating condition, thereby reducing the risk of rollover caused by platform deformation.

[0029] In this embodiment, the lifting platform 6 has multiple weight-reducing holes 65.

[0030] The principles and beneficial effects of the above technical solution: The weight-reducing holes 65 lower the weight of the lifting platform 6, resulting in a smaller load on the lifting system 5, smoother lifting, and reduced platform swaying caused by inertia. Simultaneously, the well-placed weight-reducing holes 65 maintain the overall rigidity of the platform. The reduced structural mass allows for faster dynamic response during torque application, improving system stability and lowering the overall center of gravity of the tilting vehicle, further enhancing its anti-rollover performance.

[0031] In this embodiment, the assembly vehicle body 1 includes a base plate 11; there are four lifting platforms 53, which are distributed at the four corners of the base plate 11; each lifting platform 53 includes a lifting platform body and a vertically arranged lead screw 531; the lifting platform 6 is threadedly connected to the lead screw 531; the transmission mechanism 52 includes two transmission shafts 521 and three horizontal shafts 522; the drive component 51 is disposed on the base plate 11 and located between two of the lifting platform bodies 53; the three horizontal shafts 522 are respectively connected to adjacent lifting platform bodies 53; the drive component 51 is connected to the remaining two adjacent lifting platform bodies 53 through the two transmission shafts 521; the drive component 51 is a servo motor.

[0032] The principles and beneficial effects of the above technical solution: Four lifting platforms 53 provide four-point support for the lifting platform 6, resulting in more even force distribution and significantly improved resistance to lateral loads. The lead screw 531 features a self-locking structure and high rigidity. When a large torque is transmitted from the platform to the lifting platform 53, the lead screw 531 will not rotate or loosen, thus stably maintaining the platform's posture. The lifting platform 6 is threadedly connected to the lead screw 531, allowing for precise adjustment of the platform position via the lifting platforms 53. This rigid connection ensures that the lateral reaction force of large torques is smoothly channeled into the four-point support system, completely avoiding the tilting risk caused by traditional single-point or double-point lifting systems.

[0033] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that many other modifications and implementations can be devised by those skilled in the art, which will fall within the scope and spirit of the principles disclosed herein. More specifically, various variations and modifications can be made to the components and / or layout of the subject matter combination within the scope of the disclosure, drawings, and claims. Besides variations and modifications to the components and / or layout, other uses will be apparent to those skilled in the art.
