Description

Technical Field

[0001] The utility model relates to the field of forklifts, in particular to a right-mounted forklift multi-way valve operating mechanism. Background Art

[0002] At present, the valve operating mechanism of most forklifts is generally installed in front of the right side of the driver's seat. The driver pushes / pull the joystick to drive the multi-way valve core to move up and down through the intermediate connecting rod mechanism, guiding the oil circuit in the multi-way valve to work, thereby realizing the movement of the working device.

[0003] This mechanism will partially block the driver's field of vision while driving. At the same time, the joystick is far away from the hand, and the driver's arm has a large range of operation, which can easily lead to fatigue during long-term repetitive operations. The ergonomics can be further optimized. Summary of the invention

[0019] In some embodiments, the cover bracket consists of a bending plate and two spaced-apart and symmetrically arranged support rods extending outward from the bending plate, and the multiple upper operating rods are inserted into a U-shaped space formed by the two support rods and the bending plate, and the bending plate is connected to the base.

[0020] In some embodiments, the number of the plurality of upper operating rods is four, the number of the plurality of adjusting rods is four, one operating rod is connected to one adjusting rod, and one adjusting rod is connected to one valve core.

[0021] Beneficial effects of the utility model:

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limitations on the present invention.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a right-mounted forklift multi-way valve operating mechanism is arranged in the cab and located on the right side of the driver's seat, including a cover bracket 2, a valve operating assembly 1 and a multi-way valve assembly 3. The cover bracket 2 is adapted to plastic covers of different heights through waist-shaped holes. The multi-way valve assembly 3 includes a valve body, a valve core, etc. The valve operating assembly 1 is composed of a base 4, an operating connecting rod assembly, a support pin 6, etc.

[0036] The base 4 in the valve operating assembly 1 is a structural basic part connecting the frame 5 and the fixed support pin 6. The operating link assembly is fixed to the valve operating base 4 through the support pin 6. The operating link assembly includes a handle ball 7, an upper operating rod 8, an adjusting rod 9, a gasket 10, a sliding bearing 11, an adjusting nut 12 and a connecting pin 13. The handle ball 7 is fixed to the top of the upper operating rod 8 by a thread, the middle of the upper operating rod 8 is hinged on the support pin 6, and a sliding bearing 11 is installed between the upper operating rod 8 and the support pin 6 to ensure smooth operation. The upper operating rods 8 at different positions are adjusted by the gasket 10 to ensure uniform and appropriate clearance. The lower end of the upper operating rod 8 is hinged to the adjusting rod 9 on the connecting pin 13, and the adjusting nut 12 is installed on the adjusting rod 9. By adjusting the height of the nut 12, the connection height of the adjusting rod 9 and the multi-way valve mounting hole is ensured to be consistent to avoid operation jams. When the operator pushes the handle ball 7, the handle ball 7 and the upper operating rod 8 are integrated, so that the upper operating rod 8 can rotate around the support pin 6, and the lower end of the upper operating rod 8 is connected to the adjusting rod 9, and the adjusting rod 9 is driven to move upward and downward, and then drives the multi-way valve core connected to it. Generally speaking, the reciprocating swing motion of the upper operating rod 8 is converted into the reciprocating linear motion of the multi-way valve core, thereby realizing the actions of gantry lifting and lowering, gantry tilting, and lateral rotation of accessories.

[0037] A further solution: there are four upper joysticks 8 in total, and their heights are arranged in a stepped manner; among the multiple upper joysticks 8, the handle ball 7 closest to the seat is the lowest above the ground, and the handle ball 7 farthest from the seat is the highest above the ground. The handle balls 7 are spaced at equal proportional intervals in the longitudinal and lateral directions, and the multiple upper joysticks 8 have bending features. In general, this structural arrangement is designed to reduce the driver's operating fatigue and is more ergonomic. At the same time, the multi-way valve control installation position is moved from the instrument frame to the right side of the driver, thereby solving the shortcoming of valve control blocking the line of sight.

[0038] A further solution: the adjusting rod 9 is composed of a rod I and a rod II threadedly connected thereto, and an adjusting nut 12 is installed at the connection between the rods I and II; when the rod I is screwed in or out on the rod II to change the length of the adjusting rod 9, the position between the rods I and II is fixed by tightening the adjusting nut 12.

[0039] Further solution: the cover bracket 2 is composed of a bending plate and two spaced and symmetrically arranged support rods extending outward from the bending plate, and multiple upper operating rods 8 are inserted into the U-shaped space formed by the two support rods and the bending plate, and the bending plate is connected to the base 4.

[0040] A further solution is that the top of the upper operating rod 8 is provided with an external thread, the handle ball 7 is provided with an internal thread hole, the handle ball 7 is fixed to the upper operating rod through threads, and the handle ball 7 is pushed to realize the rotation of the upper operating rod 8 around the support pin 6.

[0041] A further solution: the upper joystick 8 located above the support pin shaft 6 is a bent rod bent on both sides, and the multiple handle balls 7 are spaced at equal intervals in the longitudinal and transverse directions. The handle ball 7 closest to the driver's seat is the most forward, and the handle ball 7 farthest from the cab seat is the most rearward.

[0042] In summary, the structural arrangement of the utility model is designed to reduce the operating fatigue of the driver and is more ergonomic. At the same time, the multi-way valve control installation position is moved from the instrument frame to the right side of the driver, thereby solving the shortcoming of valve control blocking the line of sight. The reciprocating swing motion of the upper joystick is converted into the reciprocating linear motion of the multi-way valve core, thereby realizing the actions of gantry lifting and lowering, gantry tilting, and lateral rotation of accessories.
