Infrastructure materials, such as prefabricated components, heavy steel, building materials, etc., are large in size, heavy in weight, and of various shapes. At the construction site of engineering infrastructure, equipment installation often requires the transportation of some equipment, building materials, tools, cables, etc. At present, manual handling, manpower carts or mobile flatbed trucks are generally used for transportation. However, manpower carts or mobile flatbed trucks are generally suitable for flat ground. At the construction site of infrastructure, the ground is often uneven, and even cross-platforms are required. This is something that ordinary manpower carts or mobile flatbed trucks cannot meet the requirements of the construction site. The moving process is very complicated, which will cause the cart to lose balance and cause the cart to overturn. Manual handling is often labor-intensive and risky, and the goods are easy to fall, which will cause certain economic losses, and put forward higher requirements for transportation tools. Therefore, as a professional transportation equipment, the design and technical application of the infrastructure material transport trolley are particularly important. The connection between the body and the carriage must be firm and reliable to ensure that it does not loosen or fall off during transportation. The lifting system needs to be designed reasonably to ensure the quick and accurate connection between the door and the floor column to avoid safety accidents during loading and unloading.

[0023] The frame 1 is provided to provide a moving foundation for the entire transport trolley, and the carriage 2 is used as a carrier for loading materials. By setting a rotation connection between the door 2.3 and the floor plate 2.1, the opening and closing of the door 2.3 can be controlled as needed. The longitudinal rod 3.1 can be installed on the surface of the door 2.3 in a liftable manner and can rotate on the door 2.3 around its own axis. The position of the latch 3 can be adjusted according to different needs. The lower transverse rod 3.3 is inserted into the first limiting groove 7 of the first limiting block 4, and the top block 6 can push up the upper transverse rod 3.2 to prevent the lower transverse rod 3.3 from escaping from the first limiting groove 7, thereby maintaining a stable connection between the carriage 2 and the frame 1, preventing the carriage 2 from being displaced due to bumps during transportation, and maintaining the stability of the carriage 2.

By clamping the top block 6 in the first clamping groove 11, the upper transverse rod 3.2 is fixed in the second limiting groove 8 in the second limiting block 5, and the column 2.2 is connected to the door 2.3 to prevent the upper transverse rod 3.2 from escaping from the second limiting groove 8 during the lifting process, and the door 2.3 is opened to prevent the materials in the car 2 from falling and causing a safety accident, thereby further improving the stability and safety of the lifting process. By clamping the top block 6 in the second clamping groove 12, the upper transverse rod 3.2 is lifted up, and the lower transverse rod 3.3 is fixed in the first limiting groove 7. During ground transportation, the connection stability between the car 2 and the frame 1 is maintained to prevent the car 2 from being displaced due to bumps during transportation.

[0026] The top block 6 includes a lock block 6.1 and a lock tongue 6.2, one end of the lock block 6.1 is rotatably connected to the surface of the door 2.3, a spring 13 is arranged in the lock block 6.1, one end of the spring 13 is fixedly connected to the lock block 6.1, and the other end of the spring 13 is fixedly connected to the lock tongue 6.2. By arranging the lock block 6.1, the lock tongue 6.2 and the spring 13, the upper transverse rod 3.2 is inserted into the second limiting groove 8 of the second limiting block 5, the lock block 6.1 is rotated, the lock tongue 6.2 is compressed by the spring 13 and then reset and snapped into the first snapping groove 11, the column 2.2 is stably connected to the door 2.3, and the safety of the hoisting process is improved, the lower transverse rod 3.3 is inserted into the first limiting groove 7 of the first limiting block 4, the lock block 6.1 is rotated, the lock tongue 6.2 is compressed by the spring 13 and then reset and snapped into the second snapping groove 12, the stable connection between the carriage 2 and the frame 1 is maintained, and the stability during transportation is improved.

[0027] The first slot 11 and the second slot 12 are both right-angled triangle slots, the inner top wall of the first slot 11 is an inclined surface inclined upward near the slot opening, the inner bottom wall of the first slot 11 is a horizontal plane, the inner wall surface of the second slot 12 near the longitudinal rod 3.1 is an inclined surface inclined toward the longitudinal rod 3.1, and the inner wall surface of the second slot 12 away from the longitudinal rod 3.1 is a vertical plane.

[0028] Before loading the goods, slide the latch 3 upwards and then rotate it so that the upper transverse rod 3.2 is inserted into the third limiting groove 10 from top to bottom. At this time, the compartment door 2.3 can be opened to load the goods into the compartment 2. After loading, close the compartment door, slide the latch 3 upwards so that the upper transverse rod 3.2 is disengaged from the third limiting groove 10, and then rotate the latch 3 to slide downward until the lower transverse rod 3.3 is located below the first limiting block 4, rotate the latch 3 to the side of the first limiting block 4 and then push it up so that the lower transverse rod 3.3 is inserted into the first limiting groove 7 from bottom to top, rotate the lock block 6.1 to drive the lock tongue 6.2 to make a circular motion, and the lock tongue 6.2 compresses the spring 1313 and enters the second slot 12 to push the upper transverse rod 3.2 to fix the lower transverse rod 3.3 in the first limiting groove 7. The second slot 12 and the lock tongue 6.2 The lock block 6.1 is locked by the lock block 6.1, and the lock block 6.1 will not rotate, so that the car body 2 is effectively connected with the car body to prevent the car body 2 from being displaced due to bumps during ground transportation. After the transportation is completed, when the car body 2 needs to be hoisted as a whole, the lock tongue 6.2 is compressed and the lock block 6.1 is rotated to separate the lock tongue 6.2 and the second slot 12, and then the latch 3 is slid down and rotated to separate the lower transverse rod 3.3 from the first limiting slot 7, and then the latch 3 is slid upward and rotated to insert the upper transverse rod 3.2 into the second limiting slot 8 from top to bottom, and the lock block 6.1 is rotated to drive the lock tongue 6.2 to make a circular motion, and the lock tongue 6.2 compresses the spring 13 and enters the first slot 11. The first slot 11 and the lock tongue 6.2 cooperate to lock the lock block 6.1 and connect the door 2.3 and the column 2.2. At this time, the hoisting operation can be carried out.
