Detailed Description

The technical aspects of the present disclosure are further specifically illustrated by the following examples and with reference to the accompanying drawings, which are intended to explain the general concepts of the disclosure and should not be construed as limiting the disclosure.

The anti-smashing beam structure is particularly suitable for engineering machinery, such as a wide mining car and the like, and is particularly suitable for being installed at the top of a side plate 1 of a container of the wide engineering machinery, and is used for improving the anti-smashing performance of the side plate 1, so that the side plate 1 can have better anti-smashing performance relative to the side plate of the container in the prior art, and the welding quantity of the whole anti-smashing structure can be reduced while the toughness and the shock resistance can be improved, so that the cost is reduced. Of course, the shatter-resistant beam structure of the present disclosure may also be applied to other cargo containers for wide or narrow body vehicles or common cargo vehicles.

It should be noted that in the present disclosure, the direction is defined with reference to the direction in which the vehicle is traveling. Specifically, the direction in which the vehicle advances, i.e., the front of the vehicle head or the cab, is defined as the forward direction, and the opposite direction is defined as the rearward direction. The orientation extending in the front-rear direction is referred to as "longitudinal". The left hand side of the driver facing forward is defined as "left" and the right hand side is defined as "right". The orientation extending in the left-right direction is referred to as "lateral". Finally, the direction oriented towards the ground surface (ground) of the vehicle is referred to as "below" or "bottom", whereas the direction oriented towards the sky is referred to as "above" or "top".

Fig. 1 illustrates a perspective view of a cargo box of a vehicle in accordance with one embodiment of the present disclosure. The cargo box of the vehicle according to this embodiment includes two opposite and parallel side plates 1, a front plate connected to the front end of the side plate 1, a bottom plate connected to the bottom end of the side plate 1 and a rear plate connected to the rear end of the side plate 1, and two shatter prevention beam structures respectively provided in correspondence with the side plates 1. The two smashing-proof beam structures are respectively arranged on one side of each side plate 1, which is opposite to the other side plate 1.

Referring to fig. 1 and 2, a shatter prevention beam structure of a cargo box for a vehicle of the present disclosure may include a roof bar 2 and a shatter prevention beam body 3. The carrier rod 2 is cylindrical, extends in the longitudinal direction of the cargo box (front-rear direction as shown in fig. 1), and is attached to the top of the side panel 1. The body 3 of the impact beam also extends in the longitudinal direction of the container so as to be parallel to the roof rods 2. The smashing-preventing beam main body 3 is connected with the ejector rod 2 at the top and connected with the side plate 1 at the bottom, so that a closed cavity structure is formed by surrounding, and the strength of the top of the side plate 1 can be increased. In particular, the shatter prevention beam body 3 is configured such that the cavity structure has a substantially drop-shaped cross section.

Specifically, as shown in fig. 4, the cross section of the cavity structure is basically in a drop shape, the cross section of one end of the cavity structure close to the ejector rod 2 is smaller, and the cross section of one end of the cavity structure far away from the ejector rod 2 is larger, so that an inclined plane is formed between the top and the bottom of the anti-crushing beam main body 3, and falling stones are facilitated to fall along the inclined plane of the anti-crushing beam main body 3.

With continued reference to fig. 4 and in combination with fig. 2, according to one exemplary embodiment of the shatter prevention beam body 3, the shatter prevention beam body 3 is made of a plate-like piece and comprises a first portion 31, a second portion 32 and a third portion 33 connected in sequence. For the section shown in fig. 4, the first portion 31 is in the shape of a straight plate, is connected obliquely to the ejector rod 2, and extends downward from the ejector rod 2. The second portion 32 is a curved plate having an arc-shaped cross section and extends downward from the lower end of the first portion 31 and to a side near the third portion 33, forming a transition surface between the first portion 31 and the third portion 33. The third portion 33 is in the shape of a straight plate, is connected substantially perpendicularly to the side plate 1, and extends between the side plate 1 and the second portion 32.

It will be understood that the term "straight plate" is defined with respect to the orientation of the individual parts when assembled, wherein the straight plate means that the parts are straight in cross-section when assembled to form the body 3 of the impact beam, whether oriented in any direction. For example, the first portion 31 having a straight plate shape means that the first portion 31 is a flat plate shape having a rectangular shape as a whole, so that the cross section of the first portion 31 along the length direction or the diagonal direction thereof is a straight line.

Further, the first portion 31 is arranged tangentially to the ejector bar 2 and extends from the ejector bar 2 in a direction away from the side plate 1. The cross section of the ejector rod 2 is circular, and can be a solid rod made of screw steel or round steel. From the cross section of the anti-crushing beam structure shown in fig. 4, the top end of the cross section of the anti-crushing beam main body 3 along the vertical direction is connected to the tangent line of the ejector rod 2, and the included angle formed by the top end and the cross section of the side plate 1 is an acute angle. In this way, the first portion 31 can form a guide surface which slopes outwards from the ejector rod 2 at the top of the side plate 1 towards away from the side plate 1, so as to guide falling stones or the like to roll along the guide surface, preventing the stones from being hit directly against the side plate 1. In other embodiments, the angle between the cross-section of the body 3 and the side panels 1 in the vertical direction may be an obtuse angle or a right angle, for example when the cargo box is loaded with a light weight.

Advantageously, the first portion 31, the second portion 32 and the third portion 33 may be integral, which may be formed, for example, by stamping or bending a single sheet of steel. Of course, one or more of the first, second and third portions 31, 32, 33 may also be made of separate plates and then joined to each other to form the complete shatter-resistant beam body 3.

In a further exemplary embodiment of the shatter prevention beam structure, as shown in fig. 2 and 3, the shatter prevention beam structure further includes a plurality of reinforcing plates 4 disposed at intervals in the cavity structure, and the plurality of reinforcing plates 4 may have an outer shape matching a cross section of the cavity structure. For example, if the cross section of the cavity structure is in the shape of a substantially narrow drop with a wide bottom, the reinforcing plate 4 is also in the shape of a substantially drop, so that its periphery can be bonded to the corresponding shatter prevention beam body 3 and the ejector rod 2, and can also be bonded to the side plate 1 when the shatter prevention beam structure is connected to the side plate 1, thereby forming a certain support in the cavity structure. In particular, a groove having a shape matching that of the ejector rod 2 may be further provided at a position where the reinforcing plate 4 is connected to the ejector rod 2 so as to be welded to at least a part of the outer circumference of the ejector rod 2.

According to a further exemplary embodiment of the shatter prevention beam structure, as shown in fig. 1 to 3, the shatter prevention beam structure further comprises at least two first through holes 11 and at least two second through holes 34 for lifting. The at least two first through holes 11 are formed at intervals in the longitudinal direction of the cargo box (or vehicle) on the side panel 1, particularly on the top of the side panel 1. The at least two second through holes 34 are formed on the body 3 of the impact beam at intervals in the longitudinal direction of the cargo box (or vehicle). In the present embodiment, the position of the first through hole 11 in the side plate 1 corresponds to the position of the first portion 31 of the shatter prevention beam body 3, and thus the second through hole 34 is formed in the first portion 31. In other embodiments, the first through hole 11 and the second through hole 34 may be disposed at other positions as long as they are aligned with each other. In this way, the lifting means can pass through the first through hole 11 and the second through hole 34 in sequence so as to be able to lift or lower the side panels 1 of the container.

Further, the shatter prevention beam structure may further include at least two reinforcing pipes 5, each reinforcing pipe 5 being connected between a corresponding one of the first through holes 11 and the second through holes 34 and may be welded together with the side plate 1 at one end and welded together with the shatter prevention beam body 3 at the other end, thereby playing a supporting role between the shatter prevention beam body 3 and the side plate 1.

The disclosure also provides a cargo box comprising two oppositely arranged side plates 1 and two anti-smashing beam structures respectively corresponding to the side plates 1, and an engineering machine comprising the anti-smashing beam structure or the cargo box, especially a wide mine car.

INDUSTRIAL APPLICABILITY

The following describes the installation and use of the shatter prevention beam structure of the present disclosure, with the direction of occurrence during the description corresponding to the direction of installation of the cargo box behind the work machine for the purpose of facilitating a clearer description of the installation process.

When the anti-smashing beam structure is installed, the reinforcing plates 4 can be arranged at certain intervals, and each reinforcing plate 4 and the anti-smashing beam main body 3 are welded together in a butt joint mode. Then the frame structure thus formed is abutted against the top of the side plate 1 of the cargo box so as to extend in the longitudinal direction of the cargo box, and the bottom of the shatter prevention beam body 3 is welded to the side plate 1, whereby the shatter prevention beam body 3 is welded to the side plate 1. Next, the jack 2 is placed on top of the side plate 1 and the jack 2 is welded with the side plate 1 and the shatter prevention beam body 3. Alternatively, the carrier rod 2 and the body 3 of the impact beam and the reinforcing plate 4 therein may be welded together, and then the frame structure formed thereby may be welded to the side panel 1 of the cargo box.

Finally, the reinforcing pipe 5 is inserted into the cavity structure from the first through hole 11 or the second through hole 34, and two ends of the reinforcing pipe 5 are respectively welded with the anti-smashing beam main body 3 and the side plate 1, so that the whole cavity structure is closed, and all the constituent parts of the anti-smashing beam structure are formed into a closed whole.

As to the background art, the bending beam structure with sharp corners is hollow in structure, so that deformation is easily generated due to insufficient strength when stones fall down, and the anti-cracking performance is limited. Compared with the prior art, the anti-smashing beam structure can pass through the round ejector rod 2 arranged at the top of the side plate 1, and can guide stones falling onto the side plate 1 through the cavity structure formed by the anti-smashing beam main body 3, the ejector rod 2 and the side plate 1 and having an overall water drop-shaped cross section, so that the gravity for unloading a part of stones to fall down is used for guiding the stones to roll out of a container along the guiding surface, thereby avoiding the side plate 1 of a direct container of the stones, and reducing the probability of deformation of the side plate.

In addition, the anti-smashing beam structure disclosed by the utility model only welds the anti-smashing beam main body 3, the ejector rod 2, the reinforcing plate 4 and the reinforcing pipe 5 which are positioned at different positions, so that excessive welding quantity of the second structure in the prior art is avoided, deformation caused by welding is reduced, the total weight is reduced, the manufacturing cost is reduced, and certain cost advantages are realized.

Although the present general inventive concept has been described in conjunction with embodiments, it will be appreciated by those skilled in the art that changes and modifications may be made to these embodiments without departing from the principles and spirit of the general inventive concept.
