[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] This utility model provides a technical solution, such as Figures 1-4As shown; an auxiliary suspension device for engine set maintenance includes a base assembly 1 and a lifting suspension assembly 2; the base assembly 1 is placed on the ground and includes: two supporting base frames 11 arranged in parallel, with universal wheels 111 installed at both ends of its lower surface, and a telescopic base frame 112 slidably installed inside it, a supporting end block 113 installed at one end of the telescopic base frame 112, the same universal wheels 111 installed on the lower surface of the supporting end block 113, and an electric push rod 114 installed inside the telescopic base frame 112, the telescopic end of the electric push rod 114 being connected to the supporting base frame 11.

[0031] In this embodiment of the utility model, the two parallel supporting base frames 11 can be quickly adjusted using the casters 111, thereby increasing the overall area of ​​the base assembly 1 and making the engine more stable during hoisting.

[0032] In this embodiment of the utility model, the telescopic base frame 112 is adjusted by using an electric push rod 114 to further increase the overall support area of ​​the base assembly 1, so as to prevent the engine from tipping over during hoisting due to the center of gravity being too far forward.

[0033] Two hinged connecting rods 12 are provided on one side surface of the supporting base frame 11 and are movably hinged to the supporting base frame 11 via hinge seats. The base body 13 is located between the two supporting base frames 11. A sliding groove 131 is opened in the center of the body. A strip-shaped sliding hole 132 is opened on both sides of the sliding groove 131. A fixed slider 133 is installed at one end of the sliding groove 131. The fixed slider 133 is provided on both sides of the fixed slider 133. The hinge seats are located in the strip-shaped sliding hole 132 and are movably hinged to the hinged connecting rod 12. An adjusting slider 134 is slidably installed at the other end of the sliding groove 131. An electric push rod 135 is installed between the fixed slider 133 and the adjusting slider 134. The adjusting slider 134 is provided on both sides of the adjusting slider 134 and is movably hinged to the hinged connecting rod 12.

[0034] In this embodiment of the utility model, by using the hinged connecting rod 12 and controlling the adjustment by the electric push rod 135, the movement of the adjusting slider 134 can be used to drag the supporting base frame 11 to move horizontally, so that it can quickly adjust the distance between itself and the base body 13. On the one hand, it can shrink, reduce the area occupied, and make it easy to store. On the other hand, it can move away from the base body 13 to increase the support area, thereby ensuring the stability of the support.

[0035] In this embodiment of the utility model, the two hinged connecting rods 12 are staggered vertically and cross each other, which can support the stable movement of the base frame 11. At the same time, strip-shaped positioning holes can be provided on the hinged connecting rods 12 and positioning pins can be installed, so that the two hinged connecting rods 12 can be symmetrical during adjustment, ensuring that the supporting base frame 11 is parallel to the base body 13, thereby reducing the difficulty of operation and making it more convenient for workers to use.

[0036] In this embodiment of the utility model, by utilizing the cooperation of the sliding groove 131 with the fixed slider 133 and the adjusting slider 134, the support strength of the base body 13 can be guaranteed, and the height between the base body 13 and the ground can be kept constant during engine hoisting, making the hoisting more stable.

[0037] The lifting and suspension assembly 2 is disposed above the base body 13 and includes: a lower rotating rod 21, which is movably hinged to one end of the base body 13, and a lifting push rod 211 is disposed between the lower rotating rod 21 and the base body 13. The lifting push rod 211 is movably hinged to the base body 13 and the lower rotating rod 21 respectively; and an upper rotating rod 22, which is movably hinged to the upper end of the lower rotating rod 21, and a lifting push rod 221 is disposed between the upper rotating rod 22 and the lower rotating rod 21. The lifting push rod 221 is movably hinged to the lower rotating rod 21 and the upper rotating rod 22 respectively.

[0038] In this embodiment of the utility model, the lower rotating rod 21 and the upper rotating rod 22 are hinged together, and the height of the lifting sleeve 23 can be controlled by adjusting the extension and retraction through the first lifting push rod 211 and the second lifting push rod 221. On the one hand, it can meet the actual needs of engine lifting, and on the other hand, it can be quickly retracted to reduce its space occupation and facilitate storage.

[0039] The lifting sleeve 23 is movably hinged to the upper end of the upper rotating rod 22. A lifting push rod 231 is provided between the lifting sleeve 23 and the upper rotating rod 22. The fixed end of the lifting push rod 231 is movably hinged to the lower rotating rod 21, and the telescopic end of the lifting push rod 231 is movably hinged to the center of the lower surface of the lifting sleeve 23. A telescopic lifting rod 232 is movably inserted inside the sleeve. A lifting seat 233 is installed at one end of the telescopic lifting rod 232, and a lifting hook 234 is movably installed below the lifting seat 233.

[0040] In this embodiment of the invention, the lifting sleeve 23 is movably hinged to the upper rotating rod 22 and adjusted by the lifting push rod 231. The angle of the lifting sleeve 23 can be controlled, making the lifting range of the device more extensive, so as to meet the lifting needs of different types of engines.

[0041] In this embodiment of the invention, the position of the lifting hook 234 can be controlled by the extension and retraction of the telescopic boom 232, thereby enabling it to move above the engine for rapid lifting.

[0042] In this embodiment of the utility model, by using the lifting hook 234, workers can quickly fix the engine using auxiliary tools such as chains and bolts, and then hang the chains on the lifting hook 234 so that the engine can be lifted quickly.

[0043] In this utility model, the two hinged connecting rods 12 on one side of the supporting base frame 11 are staggered vertically and cross each other; this ensures the smooth adjustment of the supporting base frame 11 while also ensuring the supporting strength of the base body 13.

[0044] In this invention, when the electric push rod 114 extends, its telescopic end drives the adjusting slider 134 away from the fixed slider 133, causing the two supporting base frames 11 to move closer to the base body 13; when the electric push rod 114 retracts, its telescopic end drives the adjusting slider 134 closer to the fixed slider 133, causing the two supporting base frames 11 to move away from the base body 13. This facilitates control of the distance between the two supporting base frames 11, enabling the device to provide better support when hoisting the engine, and also reduces the area occupied when storing the device, making it more convenient to store.

[0045] In this invention, the lifting sleeve 23 and the telescopic boom 232 are provided with pin holes and are fixed by T-shaped pins; this allows the telescopic boom 232 to be quickly adjusted and fixed with the lifting sleeve 23, facilitating the lifting of the engine.

[0046] In this invention, the extension length of the telescopic base frame 112 is greater than the extension length of the telescopic boom 232; this ensures that the center of the engine is always above the two supporting base frames 11 during hoisting, preventing the device from tipping over and causing damage to the engine.

[0047] When using this utility model, when it is necessary to hoist the engine, the staff will move the device out and connect it to an external power source. Then, the electric push rod 135 will be controlled to retract, causing the adjusting slider 134 to move towards the fixed slider 133. Then, by using the hinged connecting rod 12, the supporting base frame 11 will gradually move away from the base body 13. When the electric push rod 135 is fully retracted, the supporting base frame 11 will be adjusted.

[0048] Subsequently, based on the actual situation, the staff controlled the electric push rod 114 to extend, so that the telescopic base frame 112 gradually extended out of the support base frame 11 and was adjusted to a suitable position to ensure that the engine could be successfully hoisted later.

[0049] Then, the staff controls the lifting push rod 1 211 and lifting push rod 221 to work simultaneously. By extending the lifting push rod 1 211 and lifting push rod 221 at the same time, they push the lower rotating rod 21 and the upper rotating rod 22 to rotate and adjust. In turn, the upper rotating rod 22 drives the hoisting sleeve 23 to gradually rise. When the hoisting sleeve 23 rises to a suitable height, the lifting push rod 1 211 and lifting push rod 221 can be controlled to stop working simultaneously.

[0050] Finally, the staff manually removed the T-pin and adjusted the extension length of the telescopic boom 232 to adjust the lifting hook 234 to the appropriate position. Then, the staff could push the device to move the lifting hook 234 above the engine.

[0051] Workers used tools such as chains and bolts to secure the engine, and then hung the chains on the lifting hook 234. They could then continue to control the lifting push rod 211 and the lifting push rod 221 to extend further, so that the lifting hook 234 would gradually rise and lift the engine.

[0052] When the lifting push rod 1 211 and lifting push rod 221 are fully extended, and the engine still needs to be raised, the lifting push rod 3 231 can be extended to allow the lifting sleeve 23 to be gradually lifted upwards by the push of the lifting push rod 3 231, so that the lifting hook 234 can continue to lift the engine until it is lifted to a suitable position. Then the device can be pushed to move the engine to the corresponding position.

[0053] When the device is finished and needs to be stored, the operator controls the electric push rod 114 to retract completely, so that the telescopic base frame 112 retracts into the support base frame 11. Then, the operator controls the electric push rod 135 to extend completely, so that the adjusting slider 134 moves to one end of the sliding groove 131. Then, the operator uses the hinge connecting rod 12 to retract the support base frame 11 to both sides of the base body 13.

[0054] Subsequently, control the lifting push rod 1 211, lifting push rod 221 and lifting push rod 3 231 to fully retract, so that the lower rotating rod 21, upper rotating rod 22 and lifting sleeve 23 retract and fold above the base body 13. Finally, remove the T-shaped pin and fully retract the telescopic lifting rod 232, thereby fully retracting and folding the device. Then the device can be stored.

[0055] In the actual implementation of this device, the telescopic boom 232 and the lifting sleeve 23 can be controlled by an electric telescopic boom to facilitate the operation and use of the staff.
