The frame is equipped with a self-retractable charging cable, and the cable length can be controlled by itself. When the trolley reaches the designated position, it is positioned and locked through the load-bearing pins arranged at the bottom.

[0039] In this embodiment, the track 1 uses wear-resistant steel rails. The bent part of the steel rail is formed by stretch bending. The track 1 uses standard track clips. A leveling device is designed under the track, and the flatness of the track 1 can be adjusted. After adjustment and installation, it is fixed by concrete. The upper plane of the track 1 is flush with the ground. When not in use, a track cover plate is configured to cover the track 1, which does not affect the passage of pedestrians and vehicles.

[0040] In this embodiment, the track 1 ranges from the preparation test room to the rear wall of the oil seal room. It ensures that the engine 4 is transported in place and can be aligned with the tail nozzle oil and gas collection device 32.

[0041] In this embodiment, the transport vehicle 2 adopts four-point support, with two points at the front and two points at the rear, ensuring the stability of the engine 4 during transportation and parking.

[0042] In this embodiment, the chassis of the transport vehicle 2 is designed to be lowered to the same horizontal plane as the wheel axles, meeting the requirement of chassis stability when transporting the engine 4.

[0043] In this embodiment, the accessories at the connection part between the transport vehicle 2 and the engine 4 adopt four-point connection at the front and rear. The front support point 221 of the engine 4 is connected by a pin column with a U-shaped opening into which a bolt can be inserted, and the rear support point 231 is connected by a lower support column with a U-shaped opening into which a bolt can be inserted.

[0044] In this embodiment, the front support point 221 is set as a rotatable and fixed pin column, and the rear support point 231 is set as a slider that can move forward, backward, left, and right. It ensures that engines 4 with different sizes can be installed smoothly.

[0045] In this embodiment, both the front and rear wheels of the transport vehicle 2 are equipped with a braking system, which is connected to the transport vehicle 2 through a brake handle to ensure reliable and efficient braking during transportation.

[0046] In this embodiment, there is a pin hole for fixing the transport vehicle 2 on the left and right sides at the lower rear part of the vehicle. When oil-sealing the engine 4, the ground pile pin seat and the vehicle pin hole are fixed with a pin to prevent the engine 4 from moving during the oil-sealing test run.

[0047] In this embodiment, the transport vehicle 2 has a wireless remote control, which is convenient for the operator to control the forward and backward movement and parking of the transport vehicle 2.

[0048] Operation process:

[0049] Drive the transport vehicle 2 into the preparation test room, and use a crane and suspension to install the engine 4 on the front support point 221 and the rear support point 231 of the transport vehicle 2 for oil seals.

In order to ensure that the position of the engine 4 can be relatively fixed with the ground during oil sealing, a fixing pin and hole are installed between the rear lower part of the transport vehicle 2 and the ground, so that the position of the transport vehicle 2 is fixed when the engine 4 is working, and it can withstand a thrust of about 1KN.

[0054] The ground rail in this embodiment

[0055] The embedded ground rail of the transport vehicle 2 adopts a load-bearing ground rail of P38. The surface of the ground rail is flush with the ground, and the steel wheels of the special transport vehicle 2 for the engine 4 can run on the ground rail. When not in use for a long time, cover the track 1 with a U-shaped cover plate to ensure the flatness of the ground.

[0056] The range of the track 1 extends from the preparation test room to the front part of the rear wall of the oil seal room, ensuring that the transport vehicle 2 of the engine 4 directly transports the engine 4 from the preparation test room to the oil seal room after installation, so that the tail nozzle of the engine 4 is inserted into the oil and gas collection device 32. After the test, transport the engine 4 back to the preparation test room through the transport vehicle 2.

[0057] The spacing of the track 1 in this embodiment is 1600mm. To ensure the transportation of the engine 4, an S-shaped turning radius is adopted. The vehicle length is about 5m, and the turning radius of the track 1 is 12m. If the above data changes, the on-site physical object shall prevail.

[0058] In order to ensure the flatness requirement of the upper surface of Rail 1, Rail 1 is embedded by means of secondary grouting. First, a shallow pit for the secondary grouting of the embedded Rail 1 is dug, and anchor bolts are embedded at the bottom of the pit. Subsequently, a support plate is connected to the anchor bolts, and the rail is supported through the support plate, and the horizontal level of the upper surface of the rail is adjusted. After adjustment, Rail 1 is fixed by a pressing plate. After being fixed, secondary grouting is carried out. Finally, it is ensured that the deviation of the top surface of Rail 1 within the full length of Rail 1 is not greater than 20 mm. After Rail 1 is embedded, the end of Rail 1 is in a concave pit, and the edge of the concave pit is covered with angle steel, and the top surface of Rail 1 is flush with the ground.
