Accompanying drawing explanation
Fig. 1 is back timber side guard board partial sectional view of the prior art;
The back timber side guard board partial structurtes sectional view that Fig. 2 provides for the utility model embodiment;
Fig. 3 is Status view when back timber side guard board that the utility model embodiment provides is subject to vertical direction pressure;
Fig. 4 is Status view when back timber side guard board that the utility model embodiment provides is subject to horizontal direction pulling force.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described in detail.The identical Reference numeral of wherein identical component represents.It should be noted that, the word "front", "rear" of use is described below, "left", "right", "up" and "down" refer to direction in accompanying drawing, word " interior " and " outward " refer to the direction towards or away from particular elements geometric center respectively.
The back timber side guard board partial structurtes sectional view that Fig. 2 provides for the utility model embodiment, as shown in Figure 2, the utility model embodiment provides a kind of back timber side guard board 1, and this back timber side guard board 1 comprises top board 11 and side plate 12, and top board 11 is vertically connected with side plate 12.
Top board 11 is identical with shape with the structure of side plate with top board of the prior art with shape with the structure of side plate 12, and it can be formed by steel plate rolling, and the model of steel plate can be between Q340 to Q690.Different with size according to the model size of hydraulic support, different steel plate thickness can be set.In the present embodiment, the range of values of thickness of top board 11 and described side plate 12 is 15mm-30mm.It will be appreciated by persons skilled in the art that the back timber side guard board 1 selecting suitable dimension according to the model of hydraulic support and size, while guarantee back timber side guard board 1 intensity, back timber side guard board 1 can be made again to be unlikely to blocked up, thus reduce material cost.
As shown in Figure 2, top board 11 is pressed in the top of side plate 12, is provided with inclined plane, is formed with groove between the end face of inclined plane and top board 11 at top board 11 bottom one end of side plate 12, is provided with the first weld seam 13 in groove.First weld seam 13 is arranged on the outside of top board 11 and side plate 12 junction, is therefore also referred to as outside weld, and the height of the first weld seam 13 specifically can set, as long as can through welding according to the thickness of top board 11 and side plate 12.The angle of inclination on inclined plane can be determined according to the performance of process equipment, makes its handling ease, and the groove obtained is easy to again welding.In the present embodiment, the angle of inclined plane and horizontal direction is 45 ° ± 1 °, those skilled in the art can also arrange corresponding inclined plane angle according to the welding procedure of reality and welding equipment, such as, inclined plane angle will ensure that welding gun can be easy to put in groove welding, makes inclined plane can not produce obstruction by Butt welding gun.
Preferably, top board 11 and angle, side plate 12 inner side connected vertically are provided with the second weld seam 14, are also referred to as inside weld.Second weld seam 14 can play to the connection of top board 11 and side plate 12 effect supplementing and strengthen, and the height of the second weld seam 14 can be 5 ± 0.5mm, and those skilled in the art can also come specifically to set according to the thickness of top board 11 and side plate 12.
Fig. 3 is Status view when back timber side guard board that the utility model embodiment provides is subject to vertical direction pressure; as shown in Figure 3; the back timber side guard board 1 that the utility model embodiment provides is when carrying the power P from vertical direction; the end face of side plate 12 is subject to the protection of top board 11; under the protection of top board 11; first weld seam 13 place is not directly by the strength of vertical direction, and the first weld seam 13 by the shearing of vertical direction, therefore can not split.
Fig. 4 is Status view when back timber side guard board that the utility model embodiment provides is subject to horizontal direction pulling force, as shown in Figure 4, the back timber side guard board 1 that the utility model embodiment provides is when carrying the power F from horizontal direction, because top board 11 is as a lateral direction penetrating plate, when being subject to lateral pull, make the total Impact direction of the first weld seam 13 and to roll layer parallel, thus avoid the lamellar tearing of side plate 12 and top board 11.Above-mentioned implication of rolling layer is as follows: steel plate has three directions (length and width, thick, represent with X, Y, Z) X-direction intensity the highest, is generally the nominal performance of steel plate; The intensity of Z-direction is minimum, far below X-direction, even also there will be laminated tearing, and Z-direction is exactly saidly roll layer.
The back timber side guard board that the utility model embodiment provides press against side plate by arranging top board, and when bearing the vertical pressure from back, force part is whole top board, protects the first weld seam, avoids weld cracking.Simultaneously, the side of the first weld seam is inclined plane, can effectively reduce stressed, back timber side guard board is when bearing the power from horizontal direction, make the total Impact direction of the first weld seam and to roll layer parallel, thus avoid the lamellar tearing of side plate and top board, the therefore overall supporting reliability that improve whole back timber side guard board.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the scope of each embodiment technical scheme of the utility model.
