利点がある。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a work vehicle cabin (operating cabin) which is located above a fixed position in order to obtain a wide field of view in various construction or cargo handling operations according to the working conditions. Relates to a device which can be freely moved forward. [0002] A driver's view from a cabin of a working vehicle is widened.
With equipment to move the cabin upwards
Vehicles are known (for example, Japanese Patent Application Laid-Open No. 10-88618). This
The device is placed almost upright on the fixed base member on the chassis.
The upper part of the fixed bracket member and the
A pair of parallel phosphors between the back support plates of the platform member
Hydraulic pressure between the connecting pins that are
It is configured by connecting cylinders, and the cabin is placed on the base member.
It is to raise. Therefore, this device creates a cabin
Moving the vehicle forward from its steady position on the
It is also impossible to move it forward from the stand. [0003] The present invention provides an apparatus for independently moving the cabin of a work vehicle up and down or back and forth, and keeps the size within a permissible limit of vehicle-related regulations. Provide a device capable of. [0004] The device of the present invention is a cabin mounting having a bottom frame for fixing the cabin and an upright rear wall connected to each other.
It has a base, a vertical part with a link connection part, and a horizontal plate part.
And an accommodation frame for accommodating the mounting table, on the upright rear wall.
The side part and the side plate part of the housing frame form a hydraulic cylinder for forward movement.
Is rotatably connected by the provided second parallel link
Both of the connecting portion of the vertical portion of the storage frame and a column suspended on the base
1st flat with an upper front hydraulic cylinder having an upward moving hydraulic cylinder
It is configured to be rotatably connected by a row link,
It is a device that can independently raise and lower the cabin and move forward . [0005] In this device, when the hydraulic cylinder of the first parallel link is driven, the cabin fixed to the mounting table moves upward with the accommodation frame along the base, and can be stopped at an arbitrary position within the movable range. When the hydraulic cylinder of the second parallel link is driven, it moves from the fixed rear position on the pedestal to the fixed front position at the stop position of the storage frame. That is, the second parallel
The hydraulic cylinder of the link regulates the cabin in two front and rear fixed positions. [0006] In the drawings, 1 is a working vehicle, 2 is a turning base,
Reference numeral 3 denotes an upright column fixed to the base, 4 denotes a cabin housing frame , 5 denotes a vertical portion, 6 denotes a horizontal plate portion, 6a denotes a housing recess, and 6b denotes a side plate portion. Reference numerals 7a and 7b denote link members constituting a first parallel link 8 for connecting the column 3 and the vertical portion 5, and reference numeral 9 denotes a rotation connecting portion. Reference numeral 10 denotes a first hydraulic cylinder for lifting and lowering, and reference numeral 11 denotes a pivot portion. One
2 is a mount that secures the cabin 13, a vertical back
The face wall 14 and the bottom frame 20 are continuously provided. Back wall 14
Water half top center of each side portion 16 is extended 16a rearward with rear-view notch window 15 is provided, on the upper side portion 17 of the bottom frame 20
Two shaft holes parallel to the flat part are provided. Reference numeral 21 denotes a cabin fixing bolt hole. 22a and 22b are the second parallel links 23
And are rotatably connected 18 between the side plate 6b of the housing frame and the upper side 17 of the rear wall of the mounting base. twenty four
Is a second hydraulic cylinder for moving the mounting base 12 forward with respect to the accommodation frame 4, and is a middle rear part 25 of the link member 22b.
And a pin connection between the rear portion 26 of the pedestal horizontal plate portion. In the above-mentioned apparatus, the structure of the connecting portions 9 and 18 of the first and second parallel links is arbitrary, but by adopting the connecting mechanism shown in FIG. Rolling at the time of rotation can be significantly reduced, and stability is improved. That is, an outer sleeve 31 is fixed to both ends of one connected body 30 and an inner sleeve 33 having a thrust radial bearing 34 mounted inside is fixed to the other connected body 32, and both sleeves are joined to form an inner race of the bearing 34. Into the end of the pin shaft 35 for preload, and the rear portion of the pin shaft is brought into contact with the end plate 36, and a bolt 38 is inserted through a pressing force adjusting shim 37.
Press. 39 is the grease chamber, 40 is the closing plate, 41 is
O-ring, 42 is a grease nipple. According to the present invention, the first and second hydraulic cylinders 1
The operators 0 and 24 are operated by an operator in the cabin 13, and by moving the cabin 13 to a position convenient for operating a work attachment (not shown), it is possible to improve work safety and work efficiency. Further, when the second hydraulic cylinder is in the non-working state, the cabin 13 is stably supported together with the mount 12 in the housing recess 6a of the housing frame 4. The device of the present invention has an advantage that it has a simple structure and is robust, satisfies the legal restrictions during traveling , and does not greatly increase the weight of the work vehicle.
