Embodiment Construction

[0026] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] Such as figure 1 , figure 2 , Figure 4 As shown, the mobile lifting flap operation vehicle of the present invention includes an underframe 1, a linear guide rail mechanism 2, a middle flap 10, a side flap 20, a middle protective net 11 and a side protective net 21. Underframe 1 is welded with the square pipe of 90 * 60 * 5, and rectangular cuboid shape, on the top of underframe 1, a side of quadrilateral, linear guide rail mechanism 2 is set. A central protective net 11 is provided on the linear guide rail mechanism 2, and the central protective net 11 can move up and down along the linear guide rail mechanism 2, figure 1 The reference numerals 11 and 21 represent the state where the central protective net and the side protective net are at the uppermost state, and the numerals 11a and 21a represent the state when the centr...

Abstract

The invention relates to a mobile working vehicle with a lifting protective screening, comprising a chassis, a linear guide rail mechanism, a middle turning plate, a moving mechanism and a side turning plate. The linear guide rail mechanism is arranged on the upper part of the chassis; the middle turning plate is connected with a middle protective screening which can move up and down along the linear guide rail mechanism; the moving mechanism is arranged at the bottom of the chassis and used for longitudinal and transverse traveling of the movable working vehicle with the lifting protective screening; and the side turning plate is connected with a side protective screening. The side protective screening is hinged to two sides of the middle protective screening; the rear side of the side turning plate is hinged to a third electric push rod; and the side turning plate rotates round a hinge joint with the middle protective screening through extension or retraction of the third electric push rod. The movable working vehicle with the lifting protective screening of the invention uses a folding protective screening which can be retracted when not in use, and the turning plate which can be folded in the same way is additionally arranged on two sides of the protective screening so that the working area of the protective screening is widened. In addition, a direct current variable-frequency speed regulating technique is adopted so that the working vehicle can travel longitudinally and transversely and travel in positive and reserve directions with variable speed.

Description

technical field [0001] The invention relates to a mobile lift car, in particular to a safety protection for the top maintenance of various types of railway cars and ordinary passenger vehicles, as well as access to and from the maintenance work in the car, and replaces the function of the three-story work platform for the usual vehicle maintenance. Mobile lifting protective net work vehicle. Background technique [0002] At the construction site of the top floor maintenance of railway passenger vehicles, a three-layer operation platform is generally used to maintain the top floor of the vehicle. However, since the usual fixed three-story work platform does not have the function of movement, it needs to be erected along the direction of the car body on both sides of the vehicle to be repaired, resulting in high equipment investment, large space occupation, and no train roof operation protection function. Contents of the invention [0003] The purpose of the present invent...
