Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

In the description of the present invention, it should be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "disposed," "sleeved/connected," "connected," and the like are to be construed broadly, e.g., "connected," which may be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Referring to fig. 1-3, a welded bolster comprises a bolster body 1, wherein a lower center plate 2 is arranged in the middle of the upper surface of the bolster body 1, and the bolster body 1 is connected with the lower center plate 2; one side of the lower center plate I2 is at least provided with one side bearing 3, and each side bearing 3 is connected with the swing bolster body 1; the swing bolster body 1 is of a variable cross-section structure. The reinforcing plate 13 has at least one through hole 14 in a side wall thereof. The bottom of the side bearing 3 is provided with a connecting piece 4; the side bearing 3 is connected with the swing bolster body 1 through a connecting piece 4. A plurality of mounting holes 5 are uniformly distributed in the top of the lower center plate 2. The swing bolster body 1 comprises a first section steel 11 and a second section steel 12; the first section steel 11 and the second section steel 12 are arranged in parallel, and the first section steel 11 and the second section steel 12 are welded. Reinforcing plates 13 are arranged on the side walls of the first section steel 11 and the second section steel 12; two reinforcing plates 13 are welded to the first section steel 11 and the second section steel 12 respectively.

In the embodiment, by arranging the first lower core plate 2, because the first lower core plate 2 is provided with the plurality of mounting holes 5, a user can attach the first lower core plate 2 to the top of the bolster body 1, then pass the fastening bolt through the mounting holes 5 and fix the fastening bolt in a hole which is punched in advance on the bolster body 1, and then the mounting of the first lower core plate 2 can be realized; on the other hand, the lower core plate 2 and the swing bolster body 1 can also be directly connected into a whole in a welding mode.

By arranging the side bearing 3 and the connecting piece 4, wherein the connecting piece 4 is also provided with a mounting hole 5, a user can mount the connecting piece 4 on the swing bolster body 1 through the fastening bolt; on the other hand, the connecting piece 4 and the bolster body 1 can also be directly connected into a whole in a welding mode.

Through setting up the bolster body 1 and being the variable cross section structure, this shaped steel 11 and two 12 middle parts of shaped steel are highly big, and both ends are highly little, are formed by H shaped steel or I-steel transformation. The transformation can be carried out by cutting off central vertical plates at two end parts of H-shaped steel or I-shaped steel; after the bent angle is heated and bent, the bent angle is welded into an integral structure.

Through setting up the bolster body 1, this bolster body 1 adopts the welding method, only needs simple welding frock will reform transform shaped steel 11, shaped steel two 12 and reinforcing plate 13 welding together, and carries out necessary flaw detection to weld joint 8, guarantees welding quality.

To sum up, the bolster body 1 is welded by a simple welding tool, is formed by welding plates, is low in manufacturing cost and is particularly suitable for single-piece production and small-batch production.
