The specific working process and working principle are as follows:
as shown in fig. 1-6, the lower end of the operating rod 4 is connected by a cross-shaft 3 so that the upper end of the operating rod 4 can rotate about the cross-shaft 3. According to the lever principle, when the operating lever 4 is pulled to swing back and forth, the cross shaft 3 rotates around the Y axis, the rocker arm 5 swings back and forth to drive the lifting valve core push rod 6 to swing up and down, so that the pressing-in or the stretching of the lifting valve core 81 is controlled, the moment of the lifting valve core push rod 7, which is far away from the Y axis, is not enough to pry the lifting valve core push rod 7 to lift, the lifting valve core 82 is kept still, the pressing-in or the stretching of the lifting valve core 81 controls the on-off of a corresponding oil circuit in the multi-way valve 8, and the forward tilting or backward tilting action of; when the operating lever 4 is pulled to swing left and right, the cross shaft 3 rotates around the X axis, the rocker arm 5 swings left and right to drive the inclined valve core push rod 7 to swing up and down, so that the pressing-in or stretching of the inclined valve core 82 is controlled, the moment of the lifting valve core push rod 6, which is far away from the X axis, is not enough to pry the lifting valve core push rod 6 to lift, the lifting valve core 81 is kept still, the pressing-in or stretching of the inclined valve core 82 controls the on-off of a corresponding oil circuit in the multi-way valve 8, and the lifting or descending action of the forklift gantry;
when the operating rod 4 is actuated to the right rear direction, the cross shaft 3 rotates around the intersection point O of the X axis and the Y axis, the rocker arm 5 swings to the rear right direction to drive the lifting valve core push rod 6 and the inclined valve core push rod 7 to simultaneously stretch upwards, so that the lifting valve core 81 and the inclined valve core 82 are both pulled upwards, the on-off of the corresponding oil circuit in the multi-way valve 8 is controlled, and the backward tilting and lifting combined action of the forklift gantry is realized; when the control lever 4 is actuated in the forward left direction, the cross shaft 3 rotates around the intersection point O of the X axis and the Y axis, the rocker arm 5 swings in the forward left direction to drive the inclined valve core push rod 7 and the lifting valve core push rod 6 to simultaneously press in downwards, so that the lifting valve core 81 and the inclined valve core 82 are pressed in downwards, the on-off of the corresponding oil way in the multi-way valve 8 is controlled, and the forward tilting and descending combined action of the forklift gantry is realized.
When the fork truck is in the middle position, the operating rod 4 is not pulled, the two valve cores of the multi-way valve 8 are in the middle position under the action of the internal spring force, and the door frame of the fork truck does not act.
When the operating rod 4 independently operates one valve plate in the multi-way valve 8 (model: MSV04-3122), the four action states of the forklift gantry are as follows: when the operating rod 4 is pulled backwards, the cross shaft rotates around the Y axis, the lifting valve core push rod 6 acts upwards, the on-off of the corresponding oil circuit in the multi-way valve 8 is further controlled, and the backward tilting of the forklift gantry is realized through the control of the multi-way valve 8; when the operating lever 4 is pulled forwards, the lifting valve core push rod 6 acts downwards, and the forward tilting of the forklift gantry is realized through the control of the multi-way valve 8; when the operating rod 4 is pulled rightwards, the cross shaft rotates around the X axis, the inclined valve core push rod 7 acts upwards, the on-off of the corresponding oil way in the multi-way valve 8 is further controlled, and the lifting of the forklift gantry is realized through the control of the multi-way valve 8; when the operating lever 4 is pulled leftwards, the inclined valve core push rod 7 moves downwards, so that the on-off of the corresponding oil way in the multi-way valve 8 is controlled, and the descending of the forklift gantry is realized through the control of the multi-way valve 8.
When the operating lever 4 jointly and synchronously operates the two valve plates of the multi-way valve 8, the two action state processes of the forklift gantry are as follows: when the operating rod 4 is pulled to the right rear direction, the cross shaft 3 rotates around the center O point of the X axis and the Y axis, the rocker arm 5 drives the lifting valve core push rod 6 and the inclined valve core push rod 7 to simultaneously stretch upwards, so that the lifting valve sheet valve core 81 and the inclined valve sheet valve core 82 stretch from corresponding valve sheets of the multi-way valve 8, the on-off of corresponding oil ways in the multi-way valve 8 is further controlled, and the lifting and backward tilting combined operation of the forklift gantry is realized; when the control lever 4 is pulled to the left front, the cross shaft 3 rotates around the center O point of the X axis and the Y axis, the rocker arm 5 drives the lifting valve core push rod 6 and the inclined valve core push rod 7 to press in simultaneously, so that the lifting valve sheet valve core 81 and the inclined valve sheet valve core 82 are pressed in from corresponding valve sheets of the multi-way valve 8, the on-off of corresponding oil ways in the multi-way valve 8 is further controlled, and the combined operation of descending and forward tilting of the forklift gantry is realized.
It should be noted that the cross shaft 3 is a common universal joint, and by using its structural features, two shafts which are not on the same axis or have a large angle of break can continuously rotate at a constant angular speed, and reliably transmit torque and motion.
It should be apparent to those skilled in the art that the above embodiments are only preferred embodiments of the present invention, and therefore, the modifications and changes that can be made by those skilled in the art to some parts of the present invention still embody the principles of the present invention, and the objects of the present invention are achieved, all falling within the scope of the present invention.
