[0018] The technical solution of the utility model will be further described below in conjunction with the drawings.

[0019] Referring to the Figures 1 to 3 drawing, a trolley for laying the lower skin of a small aircraft fuselage shown in the utility model includes a vehicle body, the vehicle body is of a portal structure, ladders 100 (the climbing rods in the ladders are not shown in the figure) for construction workers to get on and off are arranged on both sides of the vehicle body, a cross beam structure 200 is arranged between the ladders 100, a workstation 300 for construction workers to lie down and construct is arranged on the cross beam structure 200, a support structure 400 for supporting the vehicle body is arranged at the bottom of the ladders 100, and a pulley assembly 500 for lifting and moving the vehicle body is arranged in the support structure 400.

[0020] In this embodiment, a reinforcing rib 600 for strengthening the overall structural strength is arranged between the cross beam structure 200 and the ladder 100, and the arrangement of the reinforcing rib 600 ensures the overall structural strength of the trolley.

[0021] In this embodiment, a sponge layer for protecting construction workers is arranged on the workstation 300 to ensure that construction workers are not scratched by the sharp edges of the workstation 300 and improve the comfort of construction workers during construction.

[0022] In this embodiment, a handrail 101 for construction workers to go up and down is provided on the ladder 100. At the same time, the handrail 101 can also be used to assist personnel in pushing the trolley, so as to adjust the construction position of the construction workers.

[0023] In this embodiment, the support structure 400 includes a trapezoidal support 401 and a backing plate 402. The ladder 100 passes through the support 401 and is fixedly connected to the support 401. A backing plate 402 is provided at the bottom of the support 401, and an anti-slip layer is provided at the bottom of the backing plate 402. The setting of the support 401 improves the overall stability of the trolley during construction, and the setting of the backing plate 402 increases the friction between the support 401 and the ground, preventing the support 401 from slipping on the ground and causing production safety accidents.

[0024] In this embodiment, the pulley assembly 500 includes a pulley 501, a hand-operated screw jack 502 and a connecting plate 503. A hand-operated screw jack 502 is provided above the pulley 501. The hand-operated screw jack 502 is fixedly connected to the support structure 400 through the connecting plate 503 to drive the support structure 400 to move up and down. A locking buckle 504 is provided on the pulley 501 to prevent the pulley 501 from sliding during construction.

[0025] The setting of the pulley assembly 500 is on the one hand to facilitate the movement of the trolley through the pulley 501, and on the other hand, to adjust the overall height of the vehicle body through the hand-operated screw jack 502, so as to facilitate the construction workers to carry out manual laying operations according to the undulations of the boat-shaped female mold.

[0026] When this application is in operation, after the construction workers climb onto the work station through the ladder 100, the auxiliary personnel push the trolley to the boat-shaped female mold through the handrail 101. After ensuring that the work station 300 where the construction workers are located is above the boat-shaped female mold, the locking buckle 504 is used to lock the pulley 501 to prevent the trolley from sliding. Then, the height of the vehicle body is adjusted through the hand-operated screw jack 502 to match the undulations of the boat-shaped female mold, so as to facilitate the construction workers to carry out manual laying operations.

[0027] The above embodiments only illustrate the principles and effects of the present invention by way of example, and are not used to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
