Detailed Description

As shown in figure 1, the labor-saving trolley for the construction site is mainly used for carrying some massive and tubular building materials, and does not comprise powdery materials such as silt or materials beyond the operable capacity range of the trolley.

The device is including removing automobile body 1, removes automobile body 1 and includes about and rear end fixed mounting's curb plate, removes automobile body 1 front end and articulates there is a sealing door 17, seals door 17 and passes through the hinge with the curb plate of one side and articulated, passes through stainless steel hasp with the curb plate of opposite side and fixes. A handle 18 is arranged on the side plate at the rear side, and the handle 18 is used for pushing the trolley to advance.

The rear part of the movable vehicle body 1 is vertically provided with a double-row chain conveying mechanism 2, the double-row chain conveying mechanism 2 consists of two groups of chain conveying mechanisms which are arranged side by side, and upper and lower chain wheels of the two groups of chain conveying mechanisms which are arranged side by side are coaxially arranged. One of the rotating shafts is driven to rotate by a driving motor. A connecting frame 3 is arranged between the double-row chain conveying mechanisms 2, and bayonets and sliding blocks are arranged on the left and right of the connecting frame 3. The connecting frame 3 is clamped with the two chains 4 through a bayonet and locked by a bolt. The connecting frame 3 is in sliding fit with a slide rail 5 on the inner side of the movable vehicle body 1 through a slide block. When the driving motor drives the double-row chain conveying mechanism 2 to move up and down, the connecting frame 3 can do linear motion up and down along the slide rail 5.

A connecting rod 6 is fixed below the connecting frame 3, and the connecting rod 6 is connected with a roller frame 7. The length of the connecting rod 6 ensures that the roller frame 7 is close to the ground when the connecting frame 3 reaches the tail end of the sliding rail 5. And the roller frame 7 comprises a frame on which the rollers are rotatably mounted by means of bearings. By providing the roller frame 7, various construction materials, tools, instruments, etc. can be conveniently carried to the cart in a rolling manner.

In addition, in order to facilitate discharging, a push plate 8 is arranged above the roller frame 7, the left side and the right side of the push plate 8 are in threaded connection with screw rods 9 through lug plates, two ends of each screw rod 9 are rotatably arranged on a connecting rod 10 above the roller frame 7, and the two screw rods 9 are driven through a driving mechanism 11.

The driving mechanism 11 comprises a first chain wheel 12 coaxially connected with the two screw rods 9, a second chain wheel 13 is installed on the corresponding connecting frame 3, and the second chain wheel 13 is installed on the connecting frame 3 through a bearing and a bearing seat. The transmission chain 14 is wound around the first chain wheel 12 and the second chain wheel 13, and the second chain wheel 13 is driven by the first motor 15.

The two motors are powered by the mobile power supply.

The working principle and the process are as follows: during feeding, the device is moved to a stacked building material (such as bricks), the sealing door 17 is opened, the driving motor is started, the double-row chain conveying mechanism 2 drives the roller frame 7 to move to a certain height, the height is opposite to the top layer of the building material, then the building material is moved onto the roller frame 7, and as rollers on the roller frame 7 can rotate, and the height of the roller frame 7 is consistent with that of the building material, certain labor saving can be realized for certain materials needing manual carrying. In the subsequent feeding process, the height of the roller frame 7 is adjusted to be always equal to the height of the high building material layer, and the building material is conveyed. After the transportation is completed, the sealing door 17 is closed and locked. The device is then pushed in motion by the handle 18. After the cart arrives at the destination, the sealing door 17 is opened, the driving motor is started, the roller frame 7 is close to the ground, then the first motor 15 is started, the left screw rod 9 and the right screw rod 9 synchronously rotate, the push plate 8 moves forwards, and due to the guiding of the guide rod 16, the push plate 8 can linearly move and finally push out all the materials in the cart.
