Embodiment Construction
[0053] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific preferred embodiments.
[0054] like Figure 1 to Figure 6 As shown, a multi-way valve operating mechanism includes a handle, two valve blocks, two electromagnetic valve groups and a bracket 25 fixed in position.
[0055] The two valve blocks are valve block I 1 and valve block II 2 respectively, and the two solenoid valve groups are solenoid valve group I 3 and solenoid valve group II 4 respectively.
[0056] The multi-way valve includes oil inlet control valve block, oil return valve block, valve block I, valve block II, solenoid valve group I and solenoid valve group II. Among them, the valve block I is used to control the first oil circuit, the valve block II is used to control the second oil circuit, the solenoid valve group I is used to control the third oil circuit, and the solenoid valve group II is used to control the fourth oil circuit. ro...

The invention discloses a multiway valve operating mechanism and a forklift. The multiway valve operating mechanism comprises a handle, two valve blocks and two solenoid valve groups. Each valve block and each solenoid valve group can control one oil line in a multiway valve to be switched on or off. The handle can be shaken in a front-rear left-right mode and comprises a handle rod and a handle ball. The handle ball is provided with four handle ball buttons. A solenoid valve of each solenoid valve group is electrically connected with a pair of handle ball buttons on the handle ball. By operation on the handle ball buttons, the action of the solenoid valve in the corresponding solenoid valve group can be controlled, and thus the corresponding oil line in the solenoid valve is controlled to be switched on or off. The two valve blocks are a valve block I and a valve block II respectively. The valve block I operates and comprises a valve rod I and a left-right link mechanism, and the valve block II operates and comprises a valve rod II and a front-rear link mechanism. The valve rod I and the valve rod II can be pressed in or stretched in the corresponding valve block of the solenoid valve. The multiway valve operating mechanism is simple to operate, low in manufacturing cost and high in operation comfort and integration, and simultaneous motions of multiple oil lines in the multiway valve can be performed simultaneously.
Description
technical field [0001] The invention relates to a forklift hydraulic operating mechanism, in particular to a multi-way valve operating mechanism and a forklift. Background technique [0002] The current forklift multi-way valve manipulation control mechanism is all installed on the instrument frame, one valve stem of the multi-way valve corresponds to one handle, and four valve stems correspond to four handles. During operation, there are following deficiencies: [0003] 1. There are many joysticks, taking up a lot of space, the operation is complicated, the operation comfort is poor, and the driver is prone to fatigue. [0004] 2. Only one handle can be operated at a time, and the four valve stems need to be controlled separately, that is, only one valve stem can be controlled, and simultaneous action of multiple valve stems cannot be realized. [0005] 3. Scattered structure layout, cumbersome operation. [0006] 4. The overall layout of the forklift is not beautiful. ...
