[0032] To make the purpose, technical solutions, and advantages of the present invention more clear, the following will be combined with the accompanying drawings to clearly and completely describe the technical solutions of the present invention. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] The following combination Figure 1-Figure 4 The movable tooling of the present invention is described.

[0034] like Figure 1 and Figure 4 As shown, the present invention provides a movable tool 1 comprising a base 11, a first frame 12, and a second frame 13. The base 11 has rollers 111 rotatably disposed at its bottom. The first frame 12 is used to mount the engine 2. The second frame 13 is disposed on the base 11 and located to one side of the first frame 12. The second frame 13 is used to mount the engine 2's cooling system 21 and fuel tank 22.

[0035] In this embodiment, rollers 111 are provided at the bottom of the base 11 of the movable fixture 1, enabling the movable fixture 1 to be moved across the ground. The base 11 is provided with a first frame 12, which is used to mount the engine 2 for fixed testing. Furthermore, a second frame 13 is provided on the base 11, which can be used to mount the cooling system 21 and fuel tank 22 for fixed testing. The second frame 13 is positioned to one side of the first frame 12, facilitating connection of the piping of the cooling system 21 and fuel tank 22 on the second frame 13 to the engine 2. During testing, heat is dissipated from the engine 2 via the cooling system 21, and fuel is supplied to the engine 2 via the fuel tank 22, thereby facilitating testing of the engine 2. If the test site needs to be changed, the engine 2 and its corresponding cooling system 21 and fuel tank 22 can be transported to the new test site via the movable fixture 1. This facilitates transport and eliminates the need for repeated disassembly and assembly of the engine 2 and external equipment, thereby improving testing efficiency.

[0036] The movable tooling 1 of the present invention is provided with a first stand 12 and a second stand 13 on a base 11. The first stand 12 is used to install a fixed engine 2, and the second stand 13 is used to install a fixed cooling system 21 and a fuel tank 22. The second stand 13 is provided on one side of the first stand 12 so as to connect the pipelines of the cooling system 21 and the fuel tank 22 to the engine 2, so that the movable tooling 1 can be used as a test bench for the engine 2 to carry out relevant tests. At the same time, rollers 111 are provided at the bottom of the base 11, so that the test personnel can transport the engine 2, the cooling system 21 and the fuel tank 22 as a whole through the movable tooling 1, and conveniently transfer them to another test site, effectively solving the defect in the prior art that the engine and external equipment are inconvenient to move when changing the test site.

[0037] It is understandable that the movable tool 1 of the present invention can be used as a test bench for experiments, and can also be used alone as a transfer tool for the engine 2 for the transfer of the engine 2.

[0038] It is understood that the roller 111 at the bottom of the base 11 is also provided with a locking mechanism that can be switched between an unlocked and locked state. In the unlocked state, the roller 111 can roll to enable the movable tool 1 to move; in the locked state, the roller 111 cannot roll, causing the movable tool 1 to remain in its current position.

[0039] Specifically, in some embodiments, Figure 1 and Figure 2 As shown, the first bracket 12 includes a first bracket 121 and a second bracket 122 arranged opposite to each other in a horizontal direction. A first connecting portion is provided on the side of the first bracket 121 facing the second bracket 122, and a second connecting portion is provided on the side of the second bracket 122 facing the first bracket 121. The first connecting portion is used to be fixedly connected to one side of the engine 2, and the second connecting portion is used to be fixedly connected to the other side of the engine 2.

[0040] In this embodiment, by setting the first bracket 121 and the second bracket 122, the first bracket 121 and the second bracket 122 are arranged opposite to each other. When installing the engine 2, the engine 2 can be first placed between the first bracket 121 and the second bracket 122, and one side of the engine 2 is fixedly connected to the first connecting part on the first bracket 121, and then the other side of the engine 2 is fixedly connected to the second connecting part of the second bracket 122. The engine 2 can be fixedly installed between the first bracket 121 and the second bracket 122, and it is also convenient to extend the relevant pipelines of the engine 2 from the gap between the first bracket 121 and the second bracket 122 to connect to external equipment.

[0041] It is understandable that a hanger for connecting to an external structure is usually installed on the engine 2, and the first connecting portion and the second connecting portion can be connected to the hanger with bolts.

[0042] Specifically, in some embodiments, Figure 2 As shown, the first bracket 121 is provided with a first horizontal beam 1211 extending in the horizontal direction, and a first connecting portion is provided on the first horizontal beam 1211. The second bracket 122 is provided with a second horizontal beam 1221 extending in the horizontal direction, and a second connecting portion is provided on the second horizontal beam 1221. The height of the first horizontal beam 1211 is higher than that of the second horizontal beam 1221.

[0043] In this embodiment, a first crossbeam 1211 and a second crossbeam 1221 are respectively provided on the first bracket 121 and the second bracket 122. The first crossbeam 1211 is provided with a first connecting portion for connecting to one side of the engine 2, and the second crossbeam 1221 is provided with a second connecting portion for connecting to the other side of the engine 2. At the same time, the first crossbeam 1211 and the second crossbeam 1221 have different heights, so that the connection points on both sides of the engine 2 are also staggered in the height direction, which has a better fixing effect on the engine 2.

[0044] Specifically, if Figure 2 As shown, the first bracket 121 and the second bracket 122 may be frame structures, the crossbeam at the top of the frame of the first bracket 121 is the first crossbeam 1211 , and the crossbeam at the top of the frame of the second bracket 122 is the second crossbeam 1221 .

[0045] Specifically, in some embodiments, Figure 1 and Figure 2 As shown, a third crossbeam 123 is connected between the first bracket 121 and the second bracket 122 , and a limiting member 124 is installed on the third crossbeam 123 . The limiting member 124 is used to be inserted into the limiting hole of the engine 2 .

[0046] In this embodiment, a third cross beam 123 is erected between the first bracket 121 and the second bracket 122. The third cross beam 123 is used to install a fixed limiting member 124. The limiting member 124 can be inserted into the limiting hole of the engine 2 to limit the engine 2 in the vertical plane, so as to cooperate with the first connecting part and the second connecting part to further limit and fix the engine 2. The structure is simple and the practical effect is good.

[0047] Specifically, in some embodiments, Figure 2 and Figure 3 As shown, the limiting member 124 includes a connecting member 1241 and a limiting rod 1242. One end of the connecting member 1241 is rotatably connected to the third cross beam 123, and the other end of the connecting member 1241 is detachably connected to the limiting rod 1242. The limiting rod 1242 is used to be inserted into the limiting hole of the engine 2.

[0048] In this embodiment, a connector 1241 is provided to connect the third crossbeam 123 and the limiting rod 1242. The connector 1241 is rotatably connected to the third crossbeam 123. The connector 1241 can rotate relative to the third crossbeam 123 to adjust the position of the limiting rod 1242. This allows the position of the limiting rod 1242 to be adjusted according to the specific model of the engine 2, so that it can be inserted into the limiting hole of different models of engines 2, thereby achieving the fixed position of different models of engines 2. By detachably connecting the limiting rod 1242 and the connector 1241, before installing the engine 2, the limiting rod 1242 can be removed from the connector 1241, and then the engine 2 can be moved to the first bracket 121 and the second bracket 122, thereby avoiding interference between the limiting rod 1242 and the engine 2 when the engine 2 is moved to the installation position. After the engine 2 reaches the installation position, the limiting rod 1242 is passed through the limiting hole of the engine 2 and connected to the connector 1241.

[0049] It can be understood that when the limit rod 1242 is adjusted to the set position, by reasonably adjusting the fastening force between the connecting member 1241 and the third cross beam 123, the connecting member 1241 can be maintained in this position without large rotation, but can swing slightly with the engine 2 when the engine 2 vibrates due to changes in the working state (such as starting and stopping, acceleration and deceleration), thereby playing a buffering role.

[0050] In a specific embodiment, Figure 2 and Figure 3 As shown, a connecting seat is provided on the first crossbeam 1211 , and the connecting seat and the connecting member 1241 are hinged, and the connecting member 1241 can rotate relative to the connecting seat.

[0051] In a specific embodiment, Figure 2 and Figure 3 As shown, there are two connecting members 1241 , which are arranged side by side and are respectively connected to the two ends of the limiting rod 1242 .

[0052] In some embodiments, as Figure 1 and Figure 2 As shown, a fourth crossbeam 125 extending in the horizontal direction is provided on the top of the first bracket 121 and / or the second bracket 122 , and a hanging piece 1251 is provided on the fourth crossbeam 125 , which is used to connect with the exhaust pipe 23 of the engine 2 .

[0053] In this embodiment, a fourth cross beam 125 extending in a horizontal direction is provided on the top of the first bracket 121. The fourth cross beam 125 can extend outward and provide a support point for the hanging component 1251. The hanging component 1251 can be connected to the exhaust pipe 23 of the engine 2 to fix the exhaust pipe 23, thereby facilitating the layout of the exhaust pipe 23 and testing the engine 2.

[0054] Specifically, in some embodiments, Figure 1 As shown, a collar is provided at the bottom of the hanging member 1251 ; the collar is used to be sleeved on the exhaust pipe 23 of the engine 2 .

[0055] In some embodiments, as Figure 1 As shown, a third connecting portion is provided on the outer wall of the first rack 12 , and the third connecting portion is used to be fixedly connected to the power supply device 24 .

[0056] In this embodiment, a third connection portion is provided on the outer side of the first test stand 12 , and the third connection portion is used to install a fixed power supply device 24 . The power supply device 24 is used to connect to the engine 2 to supply power to the engine 2 so as to test the engine 2 .

[0057] In some embodiments, as Figures 1 to 4As shown, the movable tooling 1 further includes a shock absorber 14 , which is installed between the base 11 and the first stand 12 .

[0058] In this embodiment, a shock absorber 14 is installed between the base 11 and the first frame 12 to prevent the vibration of the engine 2 during operation from being transmitted from the first frame 12 to the base 11 during the test, and from being transmitted from the base 11 and the second frame 13 to other equipment, thereby making the entire movable tooling 1 more stable during the test.

[0059] In some embodiments, as Figure 1 and Figure 3 As shown, second stand 13 includes a third bracket 131 and a fourth bracket 132. Third bracket 131 is mounted on base 11 and has a hollow frame structure. A mounting cavity communicating with the outside is formed within the hollow frame structure and is used to mount oil tank 22. Fourth bracket 132 is disposed on top of third bracket 131 and is used to connect to the heat sink of cooling system 21.

[0060] In this embodiment, third bracket 131 is configured as a hollow frame structure, forming a mounting cavity. This open mounting cavity communicates with the exterior, allowing for assembly and disassembly of fuel tank 22 within the mounting cavity. Furthermore, third bracket 131 serves as a support point for fourth bracket 132, which is the top of third bracket 131. The heat sink of test cooling system 21 is mounted on fourth bracket 132, and the circulation piping on the heat sink is connected to engine 2 on first test stand 12 to dissipate heat from engine 2.

[0061] Specifically, in some embodiments, Figure 1 and Figure 3 As shown, the fourth bracket 132 includes a first longitudinal beam 1321 and a second longitudinal beam 1322 that are relatively arranged. The first longitudinal beam 1321 extends in the vertical direction, and the second longitudinal beam 1322 extends in the vertical direction. The first longitudinal beam 1321 is used to connect to one side of the heat dissipation plate, and the second longitudinal beam 1322 is used to connect to the other side of the heat dissipation plate.

[0062] In this embodiment, by providing first and second longitudinal beams 1321, 1322, and by arranging them relative to each other, when installing the heat sink, the engine 2 can be first placed between the first and second longitudinal beams 1321, 1322. One side of the heat sink can then be connected to the first longitudinal beam 1321, and the other side of the heat sink can then be connected to the second longitudinal beam 1322. This allows the heat sink to be securely mounted between the first and second longitudinal beams 1321, 1322. Furthermore, the first and second longitudinal beams 1321, 1322 extend vertically, and the heat sink installed between the first and second longitudinal beams 1321, 1322 is also arranged vertically, ensuring that the heat sink's heat dissipation surface is in full contact with the outside air, thereby improving heat dissipation efficiency.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
