[0020] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] A lifting device of a sliding arm mechanism, such as Figure 1 , 2 As shown, it includes a lifting mechanism 1, a boom assembly 2, a slewing mechanism 3, a sliding guide rail 4, a moving mechanism, and a controller.

[0022] There are two sliding guide rails 4, which are arranged along the length direction of the shelter vehicle and are installed in parallel and at intervals at the upper part of the shelter vehicle cabin. A moving mechanism is arranged between the two sliding guide rails 4.

[0023] The moving mechanism includes a pin 5, a motor 6, a sliding frame 7, and a gear 8. The pin 5 is arranged parallel to the two sliding guide rails 4 and connected to the inner wall of the shelter vehicle. The pin 5 is provided with multiple connection points connected to the shelter vehicle at intervals along its length direction to ensure the connection reliability and prevent bending deformation. The two ends of the sliding frame 7 are respectively slidably connected to the two sliding guide rails 4. The motor 6 is connected to the gear 8 and is respectively installed on one side of the sliding frame 7. The gear 8 is meshed with the pin 5. The boom assembly 2 is installed at the lower part of the sliding frame 7 through the slewing mechanism 3. The lifting mechanism 1 is installed on the boom assembly 2 and arranged at its front end.

[0024] The slewing mechanism 3 includes a motor and a slewing seat. The motor is installed at the bottom of the sliding frame 7. One side of the slewing seat is connected to the motor, and the other side is installed with the boom assembly 2. The lifting mechanism 1, the boom assembly 2, the motor, and the motor 6 are respectively connected to the controller signal.

[0025] The method for using the above-mentioned sliding boom mechanism lifting device comprises the following steps:

[0026] Step 1: The lifting mechanism descends to lift the cargo, and after the lifting mechanism moves along the sliding guide rail to the hatch of the shelter vehicle, the arm assembly extends outward to lift the cargo in the shelter vehicle to a designated position outside the cabin;

[0027] Step 2: The motor of the slewing mechanism drives the slewing seat to rotate, and the lifting mechanism is rotated through the boom assembly, and the cargo outside the cabin is lifted to the designated position inside the cabin.

[0028] The present invention adopts the reciprocating motion form of gear and pin tooth meshing, has low requirements on installation position and installation space, and is easy to maintain and repair.

[0029] The lifting mechanism is installed at the front end of the boom assembly. When the telescopic arm is extended or retracted, the lifting mechanism does not need to be operated at the same time, which reduces the operation action. When the telescopic arm of a conventional crane is extended or retracted, the lifting mechanism must be operated synchronously to ensure that the wire rope of the lifting mechanism and the telescopic arm are extended or retracted at the same time. Therefore, the operation of this device is more convenient and quick. The lower end of the slewing mechanism is installed on the upper part of the boom assembly, and the slewing action of the boom can also be realized. The upper part of the slewing mechanism is installed on the lower part of the sliding frame to ensure that the sliding frame is fixed when the boom assembly rotates. The sliding frame is installed in the sliding guide rail to ensure that the boom assembly, the slewing mechanism, and the sliding frame reciprocate at the same time.
