A linkage control box

Abstract

The invention discloses a linkage-type maneuvering box. The linkage-type maneuvering box comprises a maneuvering box shell, a height adjusting sliding rail and a damping mechanism. The maneuvering box shell is connected with a seat in a driving cab. The height adjusting sliding rail comprises an upper sliding rail and a lower sliding rail. The upper sliding rail is fixedly connected with the maneuvering box shell. The upper sliding rail slides in the lower sliding rail to achieve the linear motion in the vertical direction of the maneuvering box. The damping mechanism comprises a damper, a spring and a fixed nut. The upper end face of the damper is welded with an installing plate with open holes, and the installing plate is fixedly connected with the lower sliding rail through a bolt. The spring is connected below the damper and is fastened through the fixed nut. According to the solution of supporting and damping, a sliding mechanism is used to achieve moving of the maneuvering box in the forward and backward direction and in the up and down direction, the parallel structure of the damper and the spring is used to achieve supporting and damping of the maneuvering box, and the multi-step adjustment of a double dead lock mechanism is used to satisfy the demand on maneuvering comfort of a driver and the demand of providing constant support force to the maneuvering box.

Description

technical field [0001] The invention relates to a loader, in particular to a control box linked with a cab seat. Background technique [0002] The control box of construction machinery cab is mainly used to install hydraulic control valves, electrical control components, brake components, etc. Most of the control boxes of traditional loaders are fixed on the bottom frame of the cab by bolts. When drivers of different sizes operate the machine, they need to Adjust the front, back and height of the seat. At this time, the fixed position of the joystick cannot meet the requirements of all drivers for operating comfort; in view of the above reasons, some high-end loaders with electronically controlled gearboxes have placed the control elements in the control box. Internally, the control box is designed as a structure linked with the seat. Because the electric control handle is light in weight and small in size, the linked control box will not affect its service life due to vibra...

[0002] The control box of construction machinery cab is mainly used to install hydraulic control valves, electrical control components, brake components, etc. Most of the control boxes of traditional loaders are fixed on the bottom frame of the cab by bolts. When drivers of different sizes operate the machine, they need to Adjust the front, back and height of the seat. At this time, the fixed-position joystick cannot meet the requirements of all drivers for operating comfort; in view of the above reasons, some high-end loaders with electronically controlled gearboxes have placed the control elements in the control box. Internally, the control box is designed as a structure linked with the seat. Because the electric control handle is light in weight and small in size, the linked control box will not affect its service life due to vibration; It is heavy, and it is easy to cause the control box to crack due to vibration when it is suspended on the outside of the seat and linked with it
