Abstract
The utility model provides a hoisting mechanism of a tray truck, and solves the problems that a hoisting oil cylinder is damaged due to the fact the in a traditional hoisting mechanism, a front truck frame is unstable in hoisting. The hoisting mechanism can guarantee safe hoisting of the front truck frame, and comprises the front truck frame, a rear truck frame and the hoisting oil cylinder. The bottom of the hoisting oil cylinder is perpendicularly fixed on the rear truck frame, and the upper portion of the hoisting oil cylinder is fixed on the bottom face of a horizontal flange which is vertically supported by the front truck frame. A push frame is arranged between the front truck frame and the rear truck frame. The hoisting mechanism of the tray truck is characterized in that vertical slide grooves are symmetrically arranged on two longitudinal outer side walls of the rear truck frame, and hoisting rolling wheels are arranged on the front truck frame and located in the vertical slide grooves.
Description
Technical field
The utility model relates to the manufacturing field of storage facilities vehicle, is specially a kind of lifting mechanism of tray truck.
Background technology
Tray truck is a kind of vehicle the most frequently used in the storage facilities vehicle, it comprises front vehicle frame 1 and rear vehicle frame 2, see Fig. 1, front vehicle frame 1 and rear vehicle frame 2 are connected by lifting mechanism, traditional lifting mechanism comprises lift oil tank 3, connecting rod 4 and push away frame 5, vertical supporting 6 upper ends of front vehicle frame 1 are by connecting rod 4, the bottom is connected with the column 8 of rear vehicle frame 2 respectively by pushing away frame 5, rear vehicle frame 2 is fixed in lift oil tank 3 bottoms, upper horizontal flanges 7 bottom surfaces of front vehicle frame 1 vertical supporting 6 are fixed on top, when playing lift operations, lift oil tank 3 drives whole vertical supporting 6 upward movements by the upper horizontal flanges 7 that promotes vertical supporting 6, afterwards drive the motion that upwards hoists of whole front vehicle frame 1, the advantage of this conventional confguration is connecting rod 4 and pushes away parallelogram sturcutre 8 of four attachment points formation of frame 5, and these parallel four limit row structures can guarantee that the front vehicle frame level rises, but this parallel-crank mechanism can produce the horizontal displacement δ in the interior outside when front vehicle frame 1 level rises, see Fig. 2, and this kind horizontal displacement can damage vertically arranged lift oil tank, and also can affect the safety that front vehicle frame plays lift operations.
Summary of the invention
For the problems referred to above, the utility model provides a kind of lifting mechanism of tray truck, and its front vehicle frame that can solve traditional lifting mechanism existence hoists unstable and the problem damage lift oil tank, and can guarantee that the safety of front vehicle frame hoists.
Its technical scheme is such, it comprises front vehicle frame, rear vehicle frame and lift oil tank, described lift oil tank bottom vertical is fixed in the horizontal flanges bottom surface that described rear vehicle frame, top are fixed in described front vehicle frame vertical supporting, also be connected with between described front vehicle frame and the rear vehicle frame and push away frame, it is characterized in that: vertical two lateral walls of described rear vehicle frame are symmetrically installed with respectively vertical chute, on the described front vehicle frame roller that hoists is installed, the described roller that hoists is installed in the described vertical chute.
It is further characterized in that:
A described end that pushes away frame is installed on described front vehicle frame horizontal supporting plate side, the other end is equipped with pulley, and described rear vehicle frame is equipped with support plate, and described pulley is free to slide at described support plate.
Compare with the structure that hoists of traditional tray transport trolley, the beneficial effects of the utility model are: do dipping and heaving in the vertical chute of roller at rear vehicle frame that hoist of front vehicle frame under the drive of lift oil tank, because the roller that hoists of front vehicle frame is limited in the vertical chute of rear vehicle frame, so the horizontal displacement in the interior outside can not occur in front vehicle frame when hoisting action, thereby can guarantee the safe and reliable of lift oil tank, and guarantee that the safety of front vehicle frame hoists; In addition, an end that pushes away frame is installed on front vehicle frame horizontal supporting plate side, and the pulley that the other end is installed can be free to slide at the support plate of rear vehicle frame, can further guarantee steadily reliably hoisting of front vehicle frame when playing lift operations.
