Problems solved by technology
In the lifting process of the prior art, it is necessary to continuously press the handle back and forth, so that the liquid medium continuously enters the rodless chamber of the hydraulic cylinder from the oil pump, pushes the piston rod to move upward, the top plate of the frame is lifted, and the fork and goods are lifted. Therefore, the existing hydraulic pressure The forklift lifts slowly. In order to improve the loading and unloading efficiency, the average lifting speed of this manual hydraulic pallet truck should be increased.
In addition, when lifting heavy objects, since the handle needs to be pressed back and forth continuously, this kind of manual hydraulic pallet truck needs enough operating space during operation.

The invention discloses a ratchet wheel locking manual carrier, which comprises a frame, a pedal-rising device and a ratchet wheel locking mechanism; the ratchet wheel locking mechanism comprises a support frame, a shifting assembly, a ratchet wheel assembly, an elastic sheet and a locking block, wherein the support frame is fixed on the frame; the locking block is hinged to the frame, and a locking groove for locking the pedal-rising device is formed in the lower end of the locking block; the lower end of the elastic sheet is fixedly connected onto the support frame; the upper end of a main shifting sheet of the shifting assembly is embedded into a ratchet wheel tooth socket of the ratchet wheel assembly; a transposition block fixedly connected with a ratchet wheel in the ratchet wheel assembly is in contact with the elastic sheet; and when the elastic sheet is enabled to generate elastic deformation by the transposition block, the locking block is pushed to rotate by the elastic sheet. According to the ratchet wheel locking manual carrier disclosed by the invention, reliable locking after a cargo rises is realized, and operation is convenient.
Description
technical field [0001] The invention relates to a device for transporting heavy objects, in particular to a manual transport vehicle. Background technique [0002] As a lifting and handling tool, manual pallet trucks are widely used in factory workshops, warehouses and logistics. A manual hydraulic pallet truck is commonly used in the existing manual pallet trucks. The frame of this manual hydraulic pallet truck contains There is a load platform in the form of a set of forks, so it is generally called a manual pallet truck. The structure of this truck also includes a handle, a support seat, an oil pump arranged on the support seat, a hydraulic cylinder and a frame top plate connected to the upper end of the piston rod of the hydraulic cylinder. The top plate and the fork are connected through the front plate, and the oil pump and The hydraulic cylinder is used as the power system of the truck, and the lifting of the fork needs to be driven by the hydraulic cylinder. When t...
