Abstract

The utility model relates to a lifting seat device and a railway vehicle equipped with the device, and is characterized in that: the lifting seat device includes a bottom plate, and a lifting lug perpendicular to the bottom plate is arranged on the bottom plate, and a lifting lug is arranged on the lifting lug A baffle plate in the shape of a folded plate is fixedly connected with the bottom plate respectively on both sides. A railroad vehicle includes a plurality of jack block arrangements mounted on side beams of the railroad vehicle. Since the utility model is provided with a hanging lug perpendicular to the bottom plate on the bottom plate, and a baffle plate fastened to the bottom plate is respectively set on both sides of the lifting ear, so the device can provide sufficient tensile strength when in use, and ensure Safety during vehicle handling. Since one end of the lifting lug of the utility model is arranged in a rectangular shape and is firmly connected with the bottom plate, and the other end is arranged in an arc shape, the arrangement of one end in an arc shape during work can reduce the stress concentration generated during operation. Because the utility model fastens and connects a thickened rib plate between each baffle plate and the bottom plate, the load-bearing strength of the device is effectively improved and the service life is prolonged.

Description

Lifting seat device and railway vehicle equipped with the device

technical field

The utility model relates to a lifting seat device and a railway vehicle equipped with the device, belonging to the field of railway transportation.

Background technique

The lifting seat device is mainly used in the hoisting operation of railway vehicles, which plays the role of bearing the tensile strength of vehicles and ensuring the safety of vehicle handling. With the development of railway vehicles, the carrying capacity of railway vehicles is increasing, and the existing lifting seat structure cannot meet the use requirements due to its strength, so it is easy to cause safety problems during operation.

Contents of the invention

In view of the above problems, the purpose of this utility model is to provide a lifting seat device with simple structure and high tensile strength and a railway vehicle equipped with the device.

In order to achieve the above object, the utility model adopts the following technical solutions: a lifting seat device, which is characterized in that it includes a bottom plate, on which a lifting lug perpendicular to the bottom plate is arranged, and on the bottom of the lifting lug A baffle in the shape of a folded plate is fixedly connected with the bottom plate respectively on both sides.

A rib is fastened between each baffle plate and the bottom plate.

The lifting lug is a long plate-shaped structure, one end of the lifting lug is arranged in a rectangular shape and is tightly connected with the bottom plate, the other end of the lifting lug is arranged in an arc, and a through hole is opened at the end of the arc. .

A railway vehicle is characterized in that it includes a plurality of lifting seat devices installed on the side beams of the railway vehicle.

Because the utility model adopts the above technical scheme, it has the following advantages: 1. The utility model is provided with a lifting lug perpendicular to the base plate on the base plate, and a baffle plate fastened to the base plate is respectively arranged on both sides of the lifting ear, Therefore, the device can provide sufficient tensile strength when in use, and can ensure the safety during vehicle handling. 2. Since one end of the lifting lug of the present invention is arranged in a rectangular shape and is tightly connected with the bottom plate, and the other end is arranged in an arc, the arc-arranged end can reduce stress concentration during operation. 3. In the utility model, a thickened rib is fastened between each baffle and the bottom plate, so the load-bearing strength of the device is effectively improved and the service life is prolonged. 4. The device of the utility model has the advantages of convenient installation, simple structure and high tensile strength, which can satisfy the handling operation of railway vehicles.

detailed description

Below in conjunction with accompanying drawing and example the utility model is described in detail.

As shown in Fig. 1 and Fig. 2, the utility model device 100 is installed on the two side beams 201 of the underframe composition 200, and it includes a bottom plate 101, and a lifting lug 102 perpendicular to the bottom plate 101 is set on the bottom plate 101. Both sides of the ear 102 are respectively provided with a baffle plate 103 fastened to the bottom plate 101 and in the shape of a folded plate.

In the above embodiment, a thickened rib 104 is fastened between each baffle plate 103 and the bottom plate 101 , and the rib 104 is used to increase the bearing strength and prolong the service life.

In the above embodiment, the lifting lug 102 is a long plate-shaped structure, one end of which is arranged in a rectangular shape and is firmly connected with the bottom plate 101, and the other end is arranged in an arc, and a through hole 105 is provided at the end of the arc to facilitate the passage of the rope. , the arc setting is used to reduce the stress concentration generated during operation.

When the utility model is installed, first a plurality of devices of the utility model are respectively installed on the side beams 201 of the chassis composition 200, and the bottom plate 101, baffle plate 103 and rib 104 of each device are welded to the side beams 201 . When performing hoisting work, the rope is passed through the through hole 105 of the lifting lug 102, and fixed with the hoisting device, and then the railway vehicle is pulled upwards to complete the handling operation.

The above examples are only used to illustrate the utility model, wherein the structure, connection mode and manufacturing process of each component can be changed, and any equivalent transformation and improvement carried out on the basis of the technical solution of the utility model are not applicable. Should be excluded outside the protection scope of the present utility model.
