Abstract
The invention relates to a leveling system for a railway electrification operation vehicle, which comprises a main frame, an operation platform, a lifting upright post, and a pivoting support wherein the main frame is provided with the pivoting support which is provided with the lifting upright post; the lifting upright post is provided with the operation platform, and the operation platform is hinged to the lifting upright post; at least one adjustable extension piece is arranged between the operation platform and the lifting upright post; and one end of the adjustable extension piece is connected with the operation platform, while the other end is connected with the lifting upright post. The leveling system solves the problem that the operation platform is declined due to superelevation of an outer rail when the railway electrification operation vehicle works in a curved section. Compared with the prior art, the leveling system realizes deflection action of the operation platform by adjusting an inclination angle between the operation platform and the lifting upright post, and the operation platform can actively adjust the inclination angle relative to a horizontal plane so as to remove deflection of a vehicle body and adjust the operation platform to a horizontal position.
Description
Affiliated technical field
The present invention relates to a kind of leveling system of railway electrification working vehicle.
Background technology
Present railway electrification working vehicle, when the operation of curve location, (the railway term: superelevation of outer rail), car body and job platform produce deflection, cause workmen's dysstasia, and workpiece is placed unstability because the rail in the circuit outside is than inboard rail height.
Summary of the invention
The object of the present invention is to provide a kind ofly, be used for the leveling system of the railway electrification working vehicle of cancel job platform inclination in curve operation location.
Technical scheme of the present invention is: revolution is installed on the main car frame supports, revolution is equipped with lifting column on supporting, job platform is installed on the lifting column, the hinged installation of job platform and lifting column, between job platform and the lifting column at least one adjustable extension spare is installed, adjustable extension spare one end is connected with job platform, and the other end is connected with lifting column.
Described adjustable extension spare is hydraulic actuating cylinder, cylinder or hand gear.
Be provided with at least one lockout mechanism between job platform of the present invention and the lifting column, this mechanism is with job platform and lifting column mechanical caging, and lockout mechanism is hydraulic gear, air-actuator, motor drive mechanism or hand gear.
Compared with prior art, the present invention is by adjusting the inclination angle between job platform and the lifting column, the job platform of described vehicle can be adjusted the inclination angle by relative horizontal surface on one's own initiative, in order to cancel job platform deflection, job platform is adjusted to level attitude, convenient with the safety and the work that guarantee the workmen.
Description of drawings
The embodiment that provides below in conjunction with accompanying drawing is described in further detail the present invention.
Fig. 1 reorganizes and outfit the scheme drawing of state in the superelevation of outer rail location for the present invention.
Fig. 2 is the scheme drawing of the present invention at superelevation of outer rail location operating condition.
Fig. 3 is an embodiment of the invention scheme drawing.
The specific embodiment
Among Fig. 1, (1) is main car frame, and (2) are bogie truck, and (3) are job platform, and (4) are lifting column, and (5) are supported for revolution, and (6) are adjustable extension spare.(5) and main car frame (1) fixed installation are supported in revolution, and lifting column (4) is fixedly mounted on revolution and supports (5) upper surface, and is rotatable, job platform (3) and the hinged installation of lifting column (4).Adjustable extension spare this moment (6) is regained, and main car frame (1), job platform (3), lifting column (4), revolution are supported (5) same bogie truck (2) and together remained on obliquity.
Among Fig. 2, adjustable extension spare this moment (6) stretches out, and job platform (3) is adjusted to level attitude, and main car frame (1), lifting column (4), revolution are supported (5) same bogie truck (2) and still remained on obliquity.
Among Fig. 3, job platform (3) and the hinged installation of lifting column (4), between job platform (3) and the lifting column (4) an adjustable extension spare (6) is installed, adjustable extension spare (6) is a hydraulic actuating cylinder, its piston rod head is connected with job platform (3), and cylinder barrel end cap head is connected with lifting column (4).Job platform (3) and lifting column (4) are provided with a lockout mechanism (7), and this mechanism is a pneumatic latch, and latch inserts in the pin-and-hole of job platform (3) and lifting column (4), can be with job platform (3) and lifting column (4) mechanical caging.Reorganize and outfit state, lockout mechanism (7) latch inserts, and is in locking bit, and adjustable extension spare (6) is regained, and guarantees job platform (3) traveling safety; Operating condition, lockout mechanism (7) latch is extracted, and is in and separates lock-bit, and adjustable extension spare (6) stretches out, and makes the relative horizontal surface of job platform (3) adjust the inclination angle on one's own initiative, in order to eliminate the car body deflection, job platform (3) is adjusted to level attitude.
Claims (4)
