Abstract
A kind of electrocar is the utility model is related to, especially a kind of piston rod assembly of high stability electrocar；The purpose of this utility model is to provide a kind of piston rod assembly for ensureing decrease speed uniform high stability electrocar when pallet fork declines；It includes lift oil tank and ball screw, and the top of the piston rod on lift oil tank is provided with ball screw, and the central axis of ball screw overlaps with the central axis of piston rod；It has the characteristics that simple in construction, easy to use and reasonable in design.
Description
Technical field
A kind of electrocar is the utility model is related to, especially a kind of piston rod group of high stability electrocar
Part.
Background technology
Electrocar is used for the logistics carrier to transport goods, the goods that electrocar is carried when in use
In fork insertion pallet hole, the raising of pallet cargo and decline are realized by hydraulic system；The application of electrocar is more next at present
It is more extensive, reason be for the transport of some small freights, can with battery power more energy-conserving and environment-protective, and very convenient
With the structure of the whole carrier of simplification, electrocar more small volume and less weight is allowed, the operating efficiency of electrocar is also higher.
Current existing electrocar typically all realizes the raising of pallet cargo with by the way of vertical raising
Drop, i.e., moved up by lift oil tank and the upper surface of piston rod contacted with raising pallet fork, but because welding deformation is
Can not control completely, cause lift oil tank upper surface middle stress point produce deviation, the upper surface of lift oil tank with
In the case that raising pallet fork is with face contact, raising pallet fork levelness in raising exceeds the stress model of left and right adjusting roller
Enclose, make left and right adjusting roller stress difference too big, it is uneven so as to cause raising pallet fork decrease speed occur when empty wagons declines
Phenomenon.
For problem above, it is badly in need of us and solves.
Utility model content
The purpose of this utility model is overcome the deficiencies in the prior art, there is provided one kind ensures decrease speed when pallet fork declines
The piston rod assembly of uniform high stability electrocar.
In order to achieve the above object, the piston rod group of a kind of high stability electrocar designed by the utility model
Part, it includes lift oil tank and ball screw, and the top of the piston rod on lift oil tank is provided with ball screw, and ball screw
Central axis overlapped with the central axis of piston rod.
In accordance with the above, the piston rod assembly of a kind of high stability electrocar designed by the utility model, lead to
The top of the piston rod crossed on lift oil tank sets a ball screw, by the piston rod on lift oil tank during original raising with
Between pallet fork in a manner of face contacts stress, to contact between the ball screw being changed on lift oil tank piston rod and pallet fork
Mode stress, stress point is concentrated on the point that ball screw contacts with pallet fork, subtract pallet fork left and right adjusting roller stress deviation
It is few, so as to ensure the uniformity of pallet fork decrease speed when empty wagons declines.Therefore, it has simple in construction, easy to use and set
Count the features such as reasonable.
Brief description of the drawings
Fig. 1 is front view of the present utility model.
Embodiment
The utility model will be further described below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of piston rod assembly of high stability electrocar of the present embodiment description, it includes raising
Oil cylinder 1 and ball screw 2, the top of the piston rod on lift oil tank 1 are provided with ball screw 2, and the central shaft of ball screw 2
Line overlaps with the central axis of piston rod.
Claims (1)
- A kind of 1. piston rod assembly of high stability electrocar, it is characterised in that：It includes lift oil tank and ball screw, The top of piston rod on lift oil tank is provided with ball screw, and the central axis of the central axis of ball screw and piston rod Overlap.
