Abstract
The utility model discloses a cover plate device of a pit type synchronous car lifting jack for a railway rolling stock, which has simple structure, flexible work, reliable function and no power. The cover plate device comprises fixed cover plates (1) arranged at two sides, the key point is characterized in that an active cover plate (2) is hinged with the fixed cover plates (1) through hinge pins (3), and the inner side of the other end of the active cover plate (2) is provided with a roller (4). The cover plate device has simple structure, reasonable design, convenient operation and reliable use, can fully increase the work usable floor area with smooth and beautiful ground and easy access, can bear loads of vehicles on the ground, and can also be used for overhaul of motor train units.
Description
Technical field:
The utility model relates to rolling stock's maintenance of equipment, particularly is a kind of cover board arrangement that is used to overhaul the synchronous car lifting J-Horner of ground pit type of rolling stock.
Background technology:
After rolling stock enters shop maintenance, need vehicle to be held up by synchronous car lifting J-Horner that is fixed in ground or the synchronous car lifting J-Horner that is arranged in the foundation ditch, so that vehicle is overhauled, the synchronous car lifting J-Horner that is fixed in ground reduces effective work area in workshop, and the synchronous car lifting J-Horner in the foundation ditch then need be provided with cover board arrangement, but the unlatching of existing cover board arrangement is with automatically controlled or hydraulic pressure or even manual type, its complex structure, often be out of order, and have certain hidden danger, increase the cost of overhaul.
Summary of the invention:
Goal of the invention of the present utility model provides a kind of simple in structure, work flexibly, reliable effect need not the cover board arrangement of the synchronous car lifting J-Horner of rolling stock's ground pit type of power.
Realize that technical solution of the present utility model is as follows: comprise the securing cover plate that both sides are provided with, key is that removable cover is hinged by bearing pin and securing cover plate, and the other end inboard of removable cover is provided with roller.
The stopping means of described opening angle≤90 that are provided with a restraint cover plate °.
Described stopping means is a limit pull rod, and limit pull rod and removable cover are hinged, and the limit pull rod other end is provided with a fixed limit piece.
The utility model is simple in structure, and is reasonable in design, easy to operate, uses reliably, can fully increase the work usable floor area, and ground is smooth attractive in appearance, and is current convenient, the load that can bear the ground running vehicle, and also can be used for the maintenance of EMUs, applied range.
Description of drawings:
Fig. 1 is the overall structure schematic diagram of duty of the present utility model and off working state.
The specific embodiment:
See also Fig. 1, specific embodiment of the utility model is as follows: car lifting J-Horner is an existing product, it places in the foundation ditch, both sides, foundation ditch top are provided with the rectangle securing cover plate 1 concordant with ground, removable cover 2 is hinged by bearing pin 3 and securing cover plate 1, the other end inboard of removable cover 2 is provided with roller 4, the stopping means of opening angle≤90 of removable cover 2 and a restraint cover plate 2 ° is connected, this stopping means is made of limit pull rod 5 and fixed limit piece 6, limit pull rod 5 is a body of rod, the one end has through hole and hinged through an end of bearing pin and removable cover 2, the other end then has screw thread and the through hole and the nut 8 that pass on the fixed limit piece 6 are spirally connected, and fixed limit piece 6 is arranged on the framework in the foundation ditch, and itself and surface water horizontal line have an angle of slope, be skewed, by the opening angle of nut 8 adjustable cover plates 2; When car lifting J-Horner does not carry out the unwheeling operation, be hidden in the foundation ditch, this moment, the roller 4 of removable cover 2 abutted on the end face of holder 7 of car lifting J-Horner, and securing cover plate 1 keeps concordant with ground with removable cover 2, and removable cover 2 can bear the load (left side of Fig. 1 is looked) of ground running vehicle; When car lifting J-Horner carries out the unwheeling operation (right-hand part of Fig. 1 is looked), the holder of car lifting J-Horner 7 rising, when holder 7 is risen, the roller 4 of removable cover 2 at first rolls at holder 7 end face, then along with the continuous rising of holder 7 again the side wall surface along holder 7 roll, and backed down by holder 7 gradually, when removable cover 2 is backed down gradually, topple over to guarantee that removable cover 2 is unlikely opening angle＜90 of 5 restraint cover plates 2 of limit pull rod °; After car lifting J-Horner is finished the unwheeling operation, the holder of car lifting J-Horner 7 decline, the roller 4 of removable cover 2 rolls at the side wall surface of holder 7 earlier under the deadweight effect of removable cover, then the end face along holder 7 rolls, and closes removable cover gradually, and removable cover 2 can be provided with relative two or one, removable cover 2 has simple in structure, work is flexible, and reliable effect need not advantages such as power.
