[0031] The boxcar door lock modification positioning mold is a special mold with a specific shape and three-dimensional spatial structure formed by welding rectangular strip steel plates, angle steel plates, and square steel plates. It is used for door lock positioning during railway boxcar door lock modification construction and is a positioning auxiliary tool.

[0032] The positioning mold, reference Figures 1 to 5 , from the three-dimensional space structure, it consists of the following parts:

[0033] First, the positioning reference plate 1 is Figure 1 The number in it is 1. The positioning reference plate is an angle steel plate with the following dimensions: 100mm in length and 30*30*3mm in cross-section.

[0034] The iron stop seat longitudinal positioning plate 2 is a rectangular thick steel plate with a length of 610mm and a width of 20mm. The steel plate is made of Q235 steel plate.

[0035] The iron stop seat positioning plate 4 is an angle steel plate with dimensions of 98 mm in length and 20*20*3 mm in cross section.

[0036] The above-mentioned positioning reference plate 1 is welded and fixed to the lower end and outer side of the longitudinal positioning plate 2 of the stop iron seat, and ensures that the two are perpendicular. The triangular area of ​​the positioning reference plate 1 faces the door frame, and the bottom plate of the door frame is used as the construction reference plane, the vertical positioning reference plane.

[0037] The above-mentioned iron stop seat positioning plate 4 is welded and fixed to the uppermost end and inner side of the iron stop seat longitudinal positioning plate 2, and ensures that the two are vertical. The iron stop seat positioning plate 4 is used to fix the iron stop seat transverse positioning plate 5.

[0038] In the middle of the longitudinal positioning plate 2 of the stop iron seat, two magnet seat auxiliary positioning plates 3 are welded at an interval of 110 mm. The magnet seat auxiliary positioning plates are in two pieces and are used to cooperate with the magnet seat. The magnet seat is selected with a specification of 110*110 mm and can be firmly attracted to the door of the boxcar through magnetic force. The height of the lower plate of the magnet seat auxiliary positioning plate from the lower reference is 230 mm.

[0039] The auxiliary positioning plate 8 is welded and fixed to one side of the auxiliary positioning plate of the upper magnet seat, and together with the magnet seat positioning plate, forms a limiting structure for adsorbing the magnet seat, thereby improving the adsorption force.

[0040] A lock iron seat transverse positioning plate 5 is welded and fixed above the stop iron seat positioning plate 4. The lock iron seat transverse positioning plate 5 is an L-shaped steel plate with a right-angle corner. There is a scale on the horizontal part of the lock iron seat transverse positioning plate 5. The zero point of the scale is based on the outer edge of the vertical part of the lock iron seat transverse positioning plate 5. The scale includes three specifications of 130, 135 and 140 mm.

[0041] The longitudinal positioning plate 6 of the iron lock seat is welded to the inner side of the iron lock seat positioning plate 4 and is located below the transverse positioning plate 5 of the iron lock seat. This part is arranged parallel to the horizontal part of the transverse positioning plate 5 of the iron lock seat, and the distance between the two is 90 mm, which is equivalent to the height of the iron lock seat, that is, they enclose a space.

[0042] On the cantilever of the lock iron seat transverse positioning plate 5, three marking scales of 135mm, 140mm and 145mm are arranged in the transverse direction to facilitate the positioning reference size of the door lock buckle lock and avoid the situation that multiple improvements are required during the transverse positioning.

[0043] A reinforcing plate is added and welded between the longitudinal positioning plate 6 of the iron lock seat and the positioning plate 4 of the iron stop seat. The reinforcing plate is a square plate to enhance the welding strength between the longitudinal positioning plate 6 of the iron lock seat and the positioning plate 4 of the iron stop seat.

[0044] refer to Figure 4 , the usage is as follows:

[0045] First, use the door frame at the bottom of the boxcar as the vertical positioning reference plane, align the positioning reference plate 1 with the positioning reference plane, ensure that the longitudinal positioning plate 2 of the stop iron seat is in a vertical state, then suck the magnet block onto the door panel of the boxcar, and preliminarily fix the mold. Then place the disposable positioning door lock in the space between the horizontal positioning plate 5 of the lock iron seat and the longitudinal positioning plate 6 of the lock iron seat to achieve one-time and accurate positioning of the door lock assembly. The so-called door lock assembly includes a buckle lock seat, a door lock seat and a door lock bolt. The mold adopts a staggered design, which can simultaneously meet the 16mm positioning reference difference between the buckle lock seat and the door lock seat in the vertical direction.

[0046] The whole mold is welded and formed by Q235 steel, and has the characteristics of simple structure and convenient use. It is temporarily fixed on the door panel with a magnet block to avoid people's support and reduce labor intensity.

[0047] The embodiments described above are merely descriptions of preferred implementations of the present invention and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements to the present invention by relevant technical personnel in the field should fall within the scope of protection determined by the claims of the present invention.
