Description

False trolley

Technical Field

The utility model relates to a locomotive automobile body overhauls equipment, concretely relates to false platform truck.

Background

The false trolley is a device for supporting a trolley body in the whole assembly process, for example, when the trolley body of a motor train unit, a railway passenger train, a subway and the like is provided with a device such as a trolley lower wire casing, a pipeline, a wiring and the like, a certain operation space is required below the trolley body, and at the moment, the trolley body needs to be elevated through the false trolley, so that an operator can conveniently carry out off-train operation.

When the false trolley is not needed, the locomotive body needs to be lifted, the false trolley generally moves out of the end part of the locomotive body because the false trolley runs on the track, and the height of the false trolley support is fixed and cannot be adjusted.

In order to solve the technical problem, the utility model discloses a technical scheme does:

a false trolley comprises a trolley body and a bracket; the bracket comprises a bracket seat and a movable bracket; the bracket seat is arranged on the vehicle body; the movable frame is hinged with the bracket seat; the movable frame comprises a fixed frame and a supporting frame arranged on the fixed frame; a positioning block is arranged at the top of the support frame; a fixed block is arranged at the bottom of the support frame; the top of the bracket seat is provided with a supporting plate; a fixing groove is formed in the middle of the supporting plate; and the fixed block is matched and clamped with the fixed groove.

Further, a lead screw is arranged on the vehicle body; supporting rods are arranged on two sides of the screw rod; the bracket seat is arranged on the screw rod and the support rod.

Further, a longitudinal beam is arranged in the middle of the vehicle body; two sides of the longitudinal beam are provided with edge beams; the lead screw and the support rod are arranged between the longitudinal beam and the edge beam.

Further, a screw rod groove and a sliding groove are formed in the bottom of the support seat; the lead screw and the support rod respectively penetrate through the lead screw groove and the sliding groove.

Furthermore, the fixing frame is of a hollow triangular structure.

Furthermore, the positioning block is of a protruding structure.

Compared with the prior art, the utility model, have following advantage:

the utility model discloses a locating piece is fixed the locomotive automobile body, and when the locomotive automobile body was lifted to a take the altitude, need remove false platform truck from the bottom of locomotive automobile body, through taking the adjustable shelf to sit the upset from the support and getting off, reduce the height of whole support, then can be so that false platform truck follows the bottom of roll-off locomotive on the track.

Detailed Description

The present invention will be described in further detail with reference to specific examples, which are provided for illustrative purposes only, and are not intended to be limiting, and the scope of the present invention should not be limited thereby.

As shown in fig. 1, 2 and 3, a false trolley comprises a trolley body 1 and a bracket 2, wherein a screw rod 3 is arranged on the trolley body 1, support rods 4 are arranged on two sides of the screw rod 3, and a longitudinal beam is arranged in the middle of the trolley body 1; the lead screw 3 and the support bar 4 are arranged between the longitudinal beam and the edge beam. The bracket 2 is arranged on the screw rod 3 and the support rod 4; along with the movement of the screw rod 3, the bracket 2 can move back and forth on the vehicle body 1, so that the false trolley can support the vehicle bodies of the locomotives with different widths conveniently.

The bracket 2 comprises a bracket seat 5 and a movable frame 6, and a supporting plate 7 is arranged at the top of the bracket seat 5; a fixing groove 8 is arranged in the middle of the supporting plate 7; the bottom of the bracket seat 5 is provided with a screw rod groove 9 and a sliding groove 10; the screw rod 3 and the support rod 4 respectively penetrate through the screw rod groove 9 and the sliding groove 10 to fix the support 2.

The movable frame 6 is hinged on the bracket seat 5; the movable frame 6 comprises a fixed frame 11 and a supporting frame 12 arranged on the fixed frame 11; a positioning block 13 with a convex structure is arranged at the top of the support frame 12; the fixed frame 11 is hinged with the bracket seat 5 and can axially rotate along with the bracket seat 5; the fixing frame 11 is in a hollow triangular structure, so that the fixing frame can be pulled conveniently; the height of the positioning block 13 is higher than that of the fixing frame 11, so that the positioning block 13 can be conveniently inserted into a groove in the bottom of the locomotive body, the positioning block 13 can support the locomotive body, and the bottom of the support frame 12 is provided with a fixing block 14; the fixing block 14 can be inserted into the fixing groove 8 on the supporting plate 7; preventing the support frame 12 from loosening during operation.

Supporting a locomotive body on the track through a positioning block 13 on a support frame 12 of the false trolley and transferring the locomotive body to a fixed station, then lifting the locomotive body, and driving the support frame 12 to leave the fixed groove 8 by pulling the fixed frame 11; the whole movable frame 6 rotates to one side along with the support seat 5 in the axial direction, so that the vehicle body 1 is convenient to drive the support 2 to move away from the bottom of the locomotive body.

The embodiments of the present invention have been described with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned embodiments, which are only illustrative and not restrictive, and those skilled in the art can make many forms without departing from the spirit and scope of the present invention, and all of them fall within the protection scope of the present invention.
