Description

Technical Field

[0001] The utility model belongs to the technical field of suspended conveyor lines, and in particular relates to a double-driving block transport trolley for a suspended conveyor line. Background Art

[0002] Suspended conveyor production lines are usually used for material handling in industrial production. Usually, a transport trolley runs on the conveyor track, and a conveyor belt is arranged parallel to the conveyor track. The transmission belt drives the transport trolley to move along the conveyor track through friction, and then moves the materials suspended under the transport trolley to the next station. The driving force of the transport trolley depends on the friction between the transport trolley and the belt. The maximum driving force of the existing single trolley is about 50KG. When transporting heavy objects or transporting heavy objects from low to high places, the existing single trolley cannot meet the transportation needs and is prone to slipping.

[0003] Therefore, the above problems need to be solved urgently. Utility Model Content

Accumulation rods are respectively provided at both ends of the car body, and the car body is provided with a shaft sleeve, which is vertically arranged, and the accumulation rod is arranged through the shaft sleeve, and the accumulation rod and the shaft sleeve are slidably connected. The upper end of the accumulation rod is connected to the driving block, and the driving block is horizontally arranged. The lower end of the accumulation rod is connected to the accumulation wheel, and the accumulation rod sleeve is provided with a spring, which is arranged between the car body and the driving block, and the upper end of the spring is connected to the driving block, and the lower end of the spring is connected to the car body. During use, the load-bearing wheel provided on the car body is arranged in the track, pushing the driving block to move upward, and the driving block is squeezed on the lower surface of the belt, and friction is generated between the belt and the driving block, and the belt drives the trolley to move along the track. When accumulation is required, the stopper or rail pressure applies a downward driving force to the accumulation wheel, and the accumulation wheel drives the driving block to move downward, and the driving block and the belt are out of contact, and the trolley loses driving force. The utility model is provided with two driving blocks, which increases the friction between the trolley and the belt, improves the driving force of the single vehicle, avoids slipping during transportation, and improves the adaptability of the transport trolley.

[0006] Furthermore, in the above-mentioned double-drive block transport trolley for the suspension conveyor line, a guide wheel is sleeved on the outer side of the shaft sleeve, the guide wheel and the shaft sleeve are movably connected, an upper clamping groove is provided on the outer side of the shaft sleeve, an upper clamping spring is provided in the upper clamping groove, and the guide wheel is arranged between the upper clamping spring and the vehicle body. A lower clamping groove is provided at the lower section of the accumulation rod, and a lower clamping spring is provided in the lower clamping groove. The guide wheel is arranged in the lower opening of the guide rail, and the guide wheel moves along the lower opening of the guide rail. The lower clamping spring limits the upward movement distance of the accumulation rod, limits the movement distance of the drive block, and prevents the belt from excessive deformation.

[0007] Furthermore, in the above-mentioned double-drive block transport trolley for the suspension conveyor line, the spring is an inverted tower spring. The tower spring has a high load, good stability, a compact design and small space occupation.

[0008] Furthermore, in the above-mentioned double-drive block transport trolley for the suspended conveyor line, the drive block is provided with a positioning column, one end of the positioning column is connected to the drive block, and the positioning column extends into a through hole provided on the vehicle body. The positioning column and the accumulation rod position the drive block to prevent the drive block from rotating and ensure the stability of transportation.

[0009] Furthermore, in the above-mentioned double-drive block transport trolley for the suspended conveyor line, a bearing rod is connected to the lower side of the vehicle body, and the bearing rod is vertically connected to the vehicle body.

[0010] Furthermore, in the above-mentioned double-drive block transport trolley for the suspended conveyor line, the accumulation wheel axis is arranged horizontally.

[0011] Furthermore, in the above-mentioned double-drive block transport trolley for the suspended conveyor line, two or more accumulation rods are provided.

[0012] Furthermore, in the above-mentioned dual-drive block transport trolley for the suspended conveyor line, in order to improve the structural strength of the transport trolley, two or more load-bearing wheels are provided, and the load-bearing wheels are symmetrically arranged on both sides of the vehicle body.

[0013] It can be seen from the above technical scheme that the utility model has the following beneficial effects: the utility model uses a double drive block transport trolley for a suspended conveyor line, and two drive blocks are arranged, which increases the friction between the trolley and the belt, improves the driving force of a single vehicle, avoids slipping during transportation, and improves the adaptability of the transport trolley.
