Description

A kind of locomotive seat

Technical field

The utility model relates to the locomotive seat that a kind of locomotive cab driver uses.

Background technology

Because trainman's stream time is longer, the working strength height is taken advantage of seat so must be equipped with a comfortable suitable department, and to reduce strength at repeated alternation, raising work is renderd a service.Need to take advantage of working condition to design to satisfy the various functions of driver's job requirement in addition according to Hxn5 locomotive department.

Insufficiency of function such as existing locomotive height of seat adjusting, anteroposterior position transposition joint and corner adjusting cause its comfort level to be had a greatly reduced quality.

The utility model content

Technical problem to be solved in the utility model provides a kind of simple in structure, locomotive seat that comfort level is higher.

For solving the problems of the technologies described above, the technical solution adopted in the utility model provides a kind of locomotive seat, and it comprises: cushion, be located at the backrest on the cushion and be located at the handrail of backrest both sides; Be characterized in: the cushion below is provided with base plate, and base plate is located at and is supported the cylindrical shell top, and the bottom of supporting cylindrical shell is arranged on the mounting seat; Be provided with damper between base plate and the mounting seat, support cylindrical shell and comprise: the inner core of inside and outside socket and urceolus and be located at inner core and urceolus between spring; The sidewall of inner core and urceolus is provided with locating dowel pin.

Further, described base plate with support cylindrical shell and link to each other by plain bearing, the support cylindrical shell of base plate bottom is provided with face cam, is provided with bottom the base plate to match with this face cam with the fixing pivot pin of cushion corner, pivot pin links to each other with adjust bar.

Further, be provided with the chair plate between described cushion and the base plate, be provided with the two control slide rails that are used to adjust seat front and back displacement between cushion and the chair plate, be provided with the slip slide rail that is used to adjust cushion front and back displacement between chair plate and the base plate.

Further, be provided with catch gear between described cushion and the chair plate.

The utlity model has positive effect: in (1) the utility model, adopt support cylindrical shell and damper to regulate height of seat, comfortable reliable; This seat has two control positioies, this two positions the feet step on the ground plate height difference (difference is 76mm), therefore, seat stool face is also different, according to ergonomic, seat stool face height is that 455mm is comparatively suitable, and for this reason, this seat stool face height is designed to two grades of 451mm and 531mm, lifting adopts spring to bounce up automatically, descend and defeat urgent decline by body weight for humans, locking position adopts the automatic slippage locking of spring compressing pin rod, and release utilizes the wedge principle to carry out release.For solving the impact of oscilaltion, on footing, be provided with a damper, alleviate the oscilaltion impulsive force.(2) control position of the seat in the utility model circumferentially is mutually 180 °, adopt high strength oil-containing nylon sliding pair circumferentially to rotate, and the configuration locking device carries out locking position.(3) in the utility model, because the difference of trainman's human body height has determined seat apart from the spacing of work top difference to some extent, operate locomotive for satisfying the work driver and conductor, seat is necessary for variable range apart from the work top distance, according to the ergonomic design seat scope of moving forward and backward is 240mm, adopt the two poles of the earth to move to finish this seat to move forward and backward, the first order adopts two control slide rails to carry out seat and moves forward and backward.The second stage is adopted the slip slide rail that cushion is carried out front and back and stroke is moved.Two-stage is slided and can be improved driver and conductor's ride quality like this, reduces work fatigue intensity.(4) in the utility model,, be to reduce strength at repeated alternation because trainman's work-hours is longer, this back of seat be designed to level at 45～135 ° of turning structures, adopt manual rotary actuator to solve this angular adjustment.It is convenient to consider that the driver leaves control position, and handrail design becomes to open overturn structure.(5) in the utility model, because locomotive work position difference, required seat stool face height is also different, and this seat is provided with two retaining height and position 531mm and 455mm.This height adjustment is finished automatically by spring and is bounced up, and regulates downwards by body weight, and auto lock puts in place.Catch gear is made up of handle, spring guide.Catch gear inserts handle one end in the column automatically under the effect of spring and locks lifting position.Release only needs 90 ° of the turning handles can release, and releasing force is very little, convenient and reliable being suitable for.For preventing the oscilaltion impact, improve and take advantage of a level of comfort, the spy is provided with the oscilaltion damper.It is that dextrad is rotated 180 ° every 45 ° of one retaining locking that this seat circumferentially rotates, and this rotation is adopted plain bearing to finish seat and circumferentially rotated, and is practical reliable.Slide before and after this seat and form by two parts.It is finished by two control slide rails to move forward and backward each 100mm, in addition the cushion 62mm that can move forward.Rotary handle one seat rises automatically, and back latching device auto lock puts in place.Human body is sat and is stepped on the face, rotary handle, and seat descends, and back latching device auto lock puts in place.To level attitude, rotary seat promptly locks circumferential twist-lock handle plate to the position that makes progress to correct position again with circumferential twist-lock handle plate.Last pulling seat chair moves forward and backward control handle, and mobile cushion puts down the control handle latched position to correct position.Rotation moves forward and backward clamp handle, and mobile cushion screws handle to correct position, locking cushion position.
