[0020] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0021] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0022] like Figure 1-2 As shown, a quick-moving tooling for an engine bracket includes: a mobile trolley 6; an engine bracket 5, mounted on the mobile trolley 6 for supporting an engine; a guide device 12, mounted on the bottom of the mobile trolley 6 for guiding the mobile trolley 6 to a test station; and a locking mechanism 9, mounted on the mobile trolley 6 for locking the mobile trolley 6 at the test station.

[0023] The technical developer of this application has constructed a basic platform integrating movement, support, guidance, and locking functions, and integrated various functional modules onto the mobile trolley 6. The mobile trolley 6 serves as the main load-bearing structure, the engine bracket 5 is used to fix the engine, the guide device 12 ensures that the trolley can move accurately along a predetermined path, and the locking mechanism 9 provides rigid fixation after it is in place.

[0024] The mobile trolley 6 provides overall mobility; the engine bracket 5 is set up for dedicated engine support; the bottom guide device 12 is set up to solve the problem of inaccurate trolley movement path, ensuring that it can enter narrow or precisely aligned test positions without deviation. During operation, the mobile trolley 6 cooperates with the pre-set guide rails or guide strips on the ground and is linearly guided by the bottom guide device 12; the locking mechanism 9 is set up to solve the safety hazard that the trolley may shift due to vibration or other factors during the test. Its working principle is to firmly connect the trolley to the test bench 2 or the ground by means of mechanical pins, hydraulic clamps or bolts.

[0025] It should be noted that the mobile cart 6 can be a flatbed cart with a rigid frame, a pallet cart with railings, etc.

[0026] To address the issue of differing installation positions when adapting to different engine models, in some possible implementations, a guide rail is provided at the bottom of the engine bracket 5, and the engine bracket 5 is mounted on the mobile trolley 6 via the guide rail, which is configured to allow the engine bracket 5 to move relative to the mobile trolley 6.

[0027] The engine mount 5 is mounted on the mobile trolley 6 via guide rails. This allows the engine mount 5 to slide back and forth relative to the trolley base, fine-tuning the final installation position of the engine to ensure precise alignment of the engine output shaft with the main shaft of the test bench 2. Specifically, the operator can loosen the fixing bolts, push the engine mount 5 along the guide rail to the desired position, and then tighten it. The guide rail can be a linear guide rail, a sliding rail, or similar type.

[0028] To achieve rapid and standardized engine installation, in some possible implementations, the engine bracket 5 is provided with a tooling plate 4 for mounting and securing the engine. The tooling plate 4 can be custom-made according to the engine model, and pre-machined with threaded holes or locating pin holes that match the engine mounting holes. During operation, the engine is fixed to the tooling plate 4 with bolts, achieving a modular connection between the engine and the movable tooling 1.

[0029] To address potential positioning errors when installing the tooling plate 4 on the engine bracket 5, in some possible implementations, the tooling plate 4 is precisely positioned using a positioning block 7. The positioning block 7, typically a precision-machined steel block, is fixed to the engine bracket 5 and mates with corresponding slots or holes on the tooling plate 4, ensuring consistent positioning each time the tooling plate 4 is installed, thereby guaranteeing the repeatability of the engine's position.

[0030] To enhance the torsional and lateral stability of the mobile trolley 6 during testing, in some possible implementations, the locking mechanisms 9 are symmetrically arranged on the left and right sides of the side of the mobile trolley 6 opposite to the test platform 2. This avoids the torque problems that may exist with unilateral locking by symmetrically arranging the locking mechanisms 9 on the left and right sides of the trolley. This symmetrical layout allows for a uniform distribution of locking force, ensuring the trolley remains absolutely stable under test vibrations and improving the safety of equipment operation. The locking mechanisms 9 on both sides operate simultaneously, firmly fixing both sides of the trolley to the base of the test platform 2.

[0031] It should be noted that the locking mechanism 9 can be multiple points arranged symmetrically, rather than just one on each side.

[0032] To simplify the external piping connections of the test bench 2 and improve equipment integration and mobility, in some possible implementations, the mobile cart 6 integrates an intercooler 11. By directly integrating the intercooler 11 onto the mobile cart 6, the high-temperature intake air after engine boost can be directly connected to the on-board intercooler 11, eliminating the need for additional, lengthy intercooler 11 piping connections after moving to the workstation. The intercooler 11 is fixed to the cart by a bracket, and its inlet and outlet are connected to the corresponding engine interfaces via hoses or quick connectors. This improves testing efficiency.

[0033] To achieve rapid, one-time connection of engine oil, water, electricity, and sensor signal lines to test bench 2, avoiding tedious manual connection step by step, in some possible implementations, the mobile trolley 6 also integrates a docking interface board 8 for connecting oil, water, electricity, and signals to test bench 2. This interface board gathers all the corresponding quick-connect fittings for the engine-side pipelines onto a single board, providing a standard docking surface. When the trolley moves to the test station, this interface board automatically or semi-automatically docks with the corresponding interface board on test bench 2, instantly completing the connection of all media and signals. Its working principle is similar to an electrical or hydraulic quick-connect assembly.

[0034] like Figure 3 As shown, to achieve precise guidance of the mobile trolley 6 in a simple and reliable manner, the guiding device 12 is configured as a guide groove. In some possible embodiments, the guiding device 12 is a guide groove. The guide groove cooperates with a guide rail (or guide bar) fixed on the ground to form a sliding guide pair. Its working principle is that the guide groove is engaged with the guide rail, restricting the trolley's degree of freedom of movement perpendicular to the rail direction, allowing it to move only in a straight line along the rail direction, thus ensuring the accuracy of the movement path. This structure is simple to manufacture and has a strong load-bearing capacity.

[0035] like Figure 3 As shown, in order to further achieve precise positioning between the trolley and the test bench 2, in some possible embodiments, the bottom of the mobile trolley 6 is also provided with a positioning device 13. The positioning device 13 can be a precision-machined positioning block 7 with a positioning groove, which cooperates with the corresponding positioning structure on the test bench 2 to achieve preliminary positioning.

[0036] To facilitate labor-saving handling of the mobile trolley 6, in some possible embodiments, the bottom of the mobile trolley 6 is equipped with guide wheels. The guide wheels mainly bear the weight and roll the trolley, allowing the operator to easily push the trolley fully loaded with the engine.

[0037] To further enhance the flexibility of the mobile trolley 6, enabling it to move and turn in any direction in non-guided areas, in some possible implementations, the guide wheels are omnidirectional wheels 3. The omnidirectional wheels 3 can rotate 360 ​​degrees, making the trolley highly maneuverable, facilitating turning and direction adjustments within the workshop, and easily pushing it from the preparation area to the starting point of the guide rail at the testing station. Its working principle utilizes the steering mechanism at the bottom of the omnidirectional wheels 3 to achieve free steering.

[0038] The following is a detailed description of this application in conjunction with the working principle of this utility model: In the pre-assembly area, the operator first selects the corresponding tooling plate 4 according to the model of the engine 10 being tested. The tooling plate 4 is then precisely positioned and fixed to the engine bracket 5 using the positioning block 7. Next, the engine is hoisted onto the tooling plate 4 and securely fixed using manual screws. Simultaneously, the splined half-shaft connected to the engine output end is pre-assembled.

[0039] After pre-assembly, the operator pushes the mobile fixture 1. The guide wheels (preferably casters 3) at the bottom of the mobile trolley 6 make it easy and flexible to move. When the trolley is pushed to the entrance of the test station, the guide device 12 (such as a guide groove) at the bottom of the trolley aligns with the pre-set guide rail on the ground. Continuing to push the trolley, the guide groove engages with the guide rail, and the trolley begins to be precisely guided in a straight line, allowing it to slide accurately to the final test position.

[0040] When the trolley reaches the predetermined position, the positioning device 13 at its bottom (such as the precision-machined positioning block 7) cooperates with the corresponding positioning structure on the test bench 2 to achieve initial positioning. Subsequently, the operator triggers the locking mechanism 9 (such as a hydraulic pin or mechanical latch) symmetrically arranged on the left and right sides of the trolley to rigidly lock the moving trolley 6 to the test bench 2, preventing any movement during the test.

[0041] During the positioning and locking of the trolley, the pre-installed half-shaft at the engine output end automatically docks with the main shaft of test bench 2. Simultaneously, the docking interface plate 8 integrated on the mobile trolley 6 quickly connects to the corresponding interface on test bench 2 for oil, water, electricity, and signal lines. The intercooler 11 integrated on the trolley is also connected to the engine via a hose. After the test is completed, the above steps are reversed: unlock the locking mechanism 9, disconnect the docking interface, and push the trolley out of the test station to replace it with the next engine to be tested.

[0042] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
