Abstract

The invention discloses an auxiliary wheel mechanism of a pallet truck. The auxiliary wheel mechanism comprises a left supporting seat, a right supporting seat, an auxiliary support, a left auxiliarywheel assembly, a right auxiliary wheel assembly, a left shock absorbing assembly and a right shock absorbing assembly. Two ends of the auxiliary support are separately hinged between the left supporting seat and the right supporting seat. The left auxiliary wheel assembly and the right auxiliary wheel assembly are separately hinged to the bottom portions of two ends of the auxiliary support. Theleft shock absorbing assembly is fixedly connected between the top of the auxiliary support and the left supporting seat, and the right shock absorbing assembly is fixedly connected between the top ofthe auxiliary support and the right supporting seat. Since the left auxiliary wheel assembly and the right auxiliary wheel assembly are capable of achieving synchronous movement relative to a vehiclebody through the auxiliary support, and the left shock absorbing assembly and the right shock absorbing assembly are separately capable of absorbing vibration shock between the auxiliary support andthe left supporting seat and between the auxiliary support and the right supporting seat to further achieve the synchronous movement, and working alone is avoided, so that the service life is prolonged. The invention further discloses the pallet truck. The pallet truck is high in operational reliability.

Description

technical field

[0001] The invention relates to storage equipment technology, in particular to an auxiliary wheel mechanism of a pallet truck. The invention also relates to a pallet jack. Background technique

[0002] Pallet trucks usually include components such as hydraulic lifting mechanisms, forks, control handles, drive wheels, and auxiliary wheels. When carrying goods, the control handle adjusts the movement direction of the fork to insert the fork into the bottom of the pallet containing the goods, then activates the hydraulic lifting mechanism to lift the fork, and finally operates the control handle to make the lifted fork move to the target with the driving wheel land. Pallet trucks replace manual handling, which greatly reduces labor intensity and improves the efficiency of cargo handling. It is widely used in workshops, warehouses, docks, stations and other occasions. Therefore, it is particularly necessary to improve pallet trucks.
