Detailed Description

The present application is further described below with reference to specific embodiments, and it should be noted that, without conflict, any combination between the embodiments or technical features described below may form a new embodiment.

In the description of the present application, it should be noted that, for the terms of orientation, such as "central", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., it indicates that the orientation and positional relationship shown in the drawings are based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, but does not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be construed as limiting the specific scope of protection of the present application.

It is noted that the terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

Embodiments as shown in fig. 2 to 4, a triangular box for a transporter includes a triangular connecting plate 1 and side plates 2 vertically connected to both sides of the connecting plate 1, a reinforcing plate 3 is further connected to an outer edge of each side plate 2, and an upper reinforcing block 301 and a lower reinforcing block 302 are respectively provided at upper and lower ends of the reinforcing plate 3. The upper side of the upper reinforcing block 301 and the upper end faces of the side plates 2 and the connecting plate 1 together form an upper welding face 4, and the lower side of the lower reinforcing plate 3 and the lower end faces of the side plates 2 and the connecting plate 1 together form a lower welding face 5. The upper weld surface 4 formed by the upper reinforcing block 301 and the lower weld surface 5 formed by the lower reinforcing block 302 can increase the welding area at the welding position during welding, thereby dispersing the stress at the welding position and improving the connection strength at the welding position.

In order to provide an effective stress dispersion effect, the lengths of the upper reinforcing block 301 and the lower reinforcing block 302 are not less than 2cm, and the upper reinforcing block 301 and the lower reinforcing block 302 which are too long do not have much influence on the improvement of the connection strength and increase the production cost, so the lengths of the upper reinforcing block 301 and the lower reinforcing block 302 are not more than 5 cm.

In order to improve the production efficiency of products, the whole triangular box can be formed in one step by stamping metal plates. Therefore, in order to simplify the punching process, the extending direction of the reinforcing plate 3 may be toward the inner side of the side plate 2, and the included angle between the reinforcing plate 3 and the side plate 2 is set to be 60 ° to 120 °, and the optimum included angle is 90 °.

In order to ensure the connection strength of all parts in the triangular box, the connection positions of the side plates 2 and the connecting plate 1 and the connection positions of the side plates 2 and the reinforcing plate 3 are all set to be arc-shaped, so that the strength is improved, the human body can be prevented from being scratched, and potential safety hazards are eliminated.

Specifically, the side plate 2 is a rectangular plate, a through hole 201 is further formed in the side plate 2, and the through hole 201 is used for installing a connecting piece of the carrying vehicle.

Since the pallet fork 111 is pressed when inserting and taking goods, which may cause the link plate 1 to deform, in order to prevent the link plate 1 from deforming excessively, a deformation groove 101 may be provided at a bottom middle position of the link plate 1, and a space for deformation of the link plate 1 is provided by the deformation groove 101.

The specific working principle is as follows:

as shown in FIG. 5, when the top bar 112 drives the cover plate 113 to pull the triangular box to move upwards, the two upper and lower welding positions of the triangular box in the prior art are all subjected to tensile force, and the maximum tensile force F is concentrated at the end of the welding position and is uniformly distributed in the thickness direction of the side plate. Assuming that the thickness of the side plate is t, the force per thickness direction is

At the moment, the maximum tensile force F of the maximum stress point can generate bending moment on the connecting plate 1, and the unit bending moment M is force on unit thickness

The product of the distance from the point of maximum force to the web 1.

As shown in FIG. 6, when the top bar 112 drives the cover plate 113 to pull the triangular box to move upwardsIn the meantime, the upper welding surface 4 and the lower welding surface 5 of the triangular box of the present application are both subjected to tensile force, and the maximum tensile force F is mainly concentrated in the length direction of the upper reinforcing block 301 and the lower reinforcing block 302, and assuming that the lengths of the upper reinforcing block 301 and the lower reinforcing block 302 are both L, the force of the maximum stress per unit length is

At the moment, the maximum tension F of the maximum stress point generates bending moment on the connecting plate 1, and the unit bending moment M is force on the unit length

The product of the distance from the point of maximum force to the web 1.

Therefore, in summary, the unit force of the maximum stress point is changed by increasing the distribution area of the stress points, so that the influence of the tensile force on the welding position is reduced by reducing the unit bending moment, and the connection strength of the welding position is improved.

The foregoing has described the general principles, essential features, and advantages of the application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, which are merely illustrative of the principles of the application, but that various changes and modifications may be made without departing from the spirit and scope of the application, and these changes and modifications are intended to be within the scope of the application as claimed.
