Abstract
A fork truck single-handle flexible shaft-operated multiple-way valve mechanism is characterized in that a handle is fixed at the swing end of a cross axle, and is respectively connected with an A end and a B end of two flexible shafts in both axial directions of the cross axle; therefore, when a flexible shaft A is pushed and pulled, the handle swings backwards and forwards with the axis of rotation coincided with that of a flexible shaft B which does not move; and when the flexible shaft B is pushed and pulled, the handle swings from side to side with the axis of rotation coincided with that of the flexible shaft A which does not move. The multiple-way valve mechanism realizes the goals: (1) during side-to-side swinging, the handle pushes and pulls one valve core of a multiple-way valve, thereby controlling the motion of a set of oil cylinders; and (2) during backward-and-forward swinging, the handle pushes and pulls another valve core of the multiple-way valve, thereby controlling the motion of another set of oil cylinders. The fork truck single-handle flexible shaft-operated multiple-way valve mechanism has the advantages that the mechanism has simple and practical structure and easy operation, and can effectively realize the function of controlling the motion of two sets of oil cylinders through operating a single handle.
Description
Technical field
The utility model relates to the work of two spools of the single stick control control fork truck multi-way valve of a kind of usefulness, can realize well controlling the fork truck monolever flexible axle manipulation multi-way valve mechanism of two group oil cylinder holding functions by handling single handle.
Background technique
Multi-way valve control mechanism on the tradition fork truck mainly adopts the structure of a valve of a Joystick control, when having two valves to control, will two Joysticks carrying out the front and back push-and-pull realizes, mechanism's complexity of a valve of this handle control, need bigger arrangement space, and all be to realize during operation by the front and back drawing handle.
Summary of the invention
The purpose of this utility model just provides has a kind ofly simplified original mechanism from structure, and used installing space also is far smaller than the required space of original mechanism.It provides fork truck to handle two spools of single handle control multi-way valve, can realize well controlling the fork truck monolever flexible axle manipulation multi-way valve mechanism of two group oil cylinder holding functions by handling single handle.
Solution of the present utility model is such: the swinging end that handle is fixed on cross axle, axially be connected with two side a and bs respectively two of cross axles with flexible axle, promptly when flexible axle A is carried out push-and-pull, handle swing this moment, its rotation axis overlaps with the rotation axis of flexible axle B, and flexible axle B is failure to actuate; When flexible axle B was carried out push-and-pull, this moment, handle swung, and its rotation axis overlaps with the rotation axis of flexible axle A, and flexible axle A is failure to actuate.Realized: when 1, handle swings multi-way valve one spool is carried out push-and-pull, promptly realize control group oil cylinder action; 2, another spool of multi-way valve is carried out push-and-pull during the handle swing, promptly realized control other group oil cylinder action.
The utility model has the advantages that simple and practical easy to operately, can realize well controlling the function of two group oil cylinders actions by handling single handle.

Accompanying drawing is embodiment of the present utility model.
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is the utility model flexible axle and cross axle linkage structure schematic representation.
Accompanying drawing 3 is handle 3 and cross axle connecting plate 4 linkage structure schematic representation.
Accompanying drawing 4 is structural representations of cross axle 5.
Accompanying drawing 5 is A end control structure schematic representation of flexible axle 2.
Accompanying drawing 6 is B end control structure schematic representation of flexible axle 2.
Embodiment
The utility model has included multichannel spool 1, flexible axle 2 and handle 3, and described handle 3 is the swinging ends that are fixed on cross axle 5, axially is connected with two side a and bs with flexible axle 2 respectively 5 two of cross axles.
In the present embodiment, be fixed with cross axle connecting plate 4 at the swinging end of cross axle 5, the side a and b of handle 3, flexible axle 2 is to be separately fixed on the cross axle connecting plate 4.
The utility model has used cross axle (accompanying drawing four) principle on handle, promptly when the A of flexible axle 2 end is carried out push-and-pull, and handle swing this moment, its rotation axis overlaps with the rotation axis of the B end of flexible axle 2, and the B of flexible axle 2 holds be failure to actuate (accompanying drawing five); When the B end to flexible axle 2 carried out push-and-pull, this moment, handle swung, and its rotation axis overlaps with the rotation axis of the A end of flexible axle 2, and the A of flexible axle 2 holds be failure to actuate (accompanying drawing six).Realized: when 1, handle swings multi-way valve one spool is carried out push-and-pull, promptly realize control group oil cylinder action; 2, another spool of multi-way valve is carried out push-and-pull during the handle swing, promptly realized control other group oil cylinder action.
Claims (2)
1. a fork truck monolever flexible axle is handled multi-way valve mechanism, include multichannel spool (1), flexible axle (2) and handle (3), it is characterized in that described handle (3) is the swinging end that is fixed on cross axle (5), axially be connected with two side a and bs respectively with flexible axle (2) (5) two of cross axles.
2. fork truck monolever flexible axle according to claim 1 is handled multi-way valve mechanism, it is characterized in that being fixed with cross axle connecting plate (4) at the swinging end of cross axle (5), the side a and b of handle (3), flexible axle (2) is to be separately fixed on the cross axle connecting plate (4).
