Description

Technical Field

[0001] The utility model belongs to the technical field of unloading tool equipment, in particular to a pulley truck for valve seat loading and unloading. Background Art

[0002] The existing pulley truck refers to a structure with rollers installed at the bottom of a flatbed truck for easy movement. After the valve seat is produced, it generally needs to be transported to different places through a transfer device. Even if the valve seats are neatly arranged inside the storage basket, the unloading of the valve seats still needs to be completed by manual handling, resulting in low efficiency.

[0003] After retrieval, for example (authorized publication number CN212289903U), a transport vehicle for cargo loading and unloading includes a transport vehicle body. Moving rollers are installed at the bottom of the transport vehicle body. A push handle is installed on one side of the transport vehicle body, and a car door is provided on the opposite side of the push handle of the transport vehicle body. The car door is connected to the transport vehicle body through a first rotating shaft. A second rotating shaft is provided on the side wall of the car door, and a locking member is movably connected to the second rotating shaft. A notch is provided on the locking member. This device is convenient for unloading the items transported on the transfer device. However, since the storage basket loaded with valve seats cannot be fixed to the transport vehicle, it is easy to tilt during movement or turning, causing the storage baskets stacked on the transport vehicle to fall, damaging the valve seats, and reducing the unloading efficiency of the device.
