Description

Technical Field

[0001] The utility model relates to the technical field of container vehicle end beams, in particular to a container vehicle end beam structure. Background Art

[0002] The main function of a container truck's end beam is to support and secure the container, ensuring the safe transportation of cargo. The design of the end beam needs to take into account the ease of loading and unloading the container, the vehicle's driving stability, and its durability under various road conditions. A container truck's end beam is typically composed of a main longitudinal beam, a main cross beam, and a tail beam. These beams are connected by welding or bolts to form a solid frame structure. The design of the end beam needs to consider its load-bearing capacity, stability, and coordination with other components. For example, reinforcing plates and connecting plates may be installed on the end beam to enhance the strength and durability of the structure.

[0003] Chinese patent announcement number CN218367987U discloses a container truck end beam structure, which uses a setting method in which a clamping block, a clamping slot, a support block and a mounting slot are matched. By sliding the two clamping blocks into the inner cavity of the clamping slot on one side of the two fixed beams, the support block is set between the two fixed beams, and then the main cross beam is moved, and the mounting slot at the bottom of the main cross beam is connected with the support block, so that the main cross beam is set on the support block, supporting the main cross beam, and stably setting the main cross beam between the two fixed beams so that the end surface of the main cross beam and the outer wall of the fixed beam are kept in a fit state, which facilitates the welding of the main cross beam; using a setting method in which a connecting rod, a mounting hole and a nut are matched, by inserting one end of the connecting rod into the inner cavity of the mounting hole on one side of the main cross beam, and then setting two adjacent main cross beams between the two fixed beams so that the other ends of the corresponding connecting rods between the two main cross beams are fit, turning the nut on one of the connecting rods to make it threadedly connected with the other end of the other connecting rod, fixing the other ends of the two connecting rods, thereby improving the bearing capacity of the main cross beams at both ends;

[0004] The above technology enhances the overall bearing capacity by adding a main cross beam and a fixing mechanism located in the same plane as the main longitudinal beam. However, the supporting effect on the end of the container truck end beam is relatively limited, which makes the container truck end beam easily deformed due to uneven force, shortening its service life. For this reason, the utility model provides a container truck end beam structure for solving the above problem. Utility Model Content

[0005] The purpose of the present utility model is to provide a container car end beam structure to solve the problem proposed in the above background technology that the traditional container car end beam only enhances the overall bearing capacity by adding a main cross beam and a fixing mechanism located in the same plane as the main longitudinal beam, and the supporting effect on the end of the container car end beam is relatively limited, which makes the container car end beam easily deformed by uneven force, thereby shortening the service life.

[0006] To achieve the above objectives, the present invention solves the above technical problems as follows:

[0007] A container vehicle end beam structure includes two parallel main longitudinal beams, a tail beam and multiple main cross beams are welded between the two main longitudinal beams, connecting columns are inserted on the main longitudinal beams and between the tail beam and the main cross beams, a load-bearing plate is screwed fixed between the two connecting columns, and multiple reinforcing plates are installed between the load-bearing plate and the tail beam, and the reinforcing plates are in the shape of a right-angled triangle.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The present invention will be further described below with reference to the embodiments.

[0026] See also Figure 1-6 The utility model provides a container vehicle end beam structure, comprising two main longitudinal beams 1 parallel to each other, with a plurality of main cross beams 3 welded and fixed between the two main longitudinal beams 1;

[0027] Specifically, the main longitudinal beam 1 and the main cross beam 3 together constitute the main structure of the container vehicle end beam. The main longitudinal beam 1 and the main cross beam 3 are parallel to each other and are welded and fixed to form a solid frame structure, which can provide good stability and bending resistance when bearing loads.

[0028] Furthermore, a tail beam 2 is welded between the two main longitudinal beams 1, an extension plate 21 is integrally formed on the upper side of the tail beam 2, and a plurality of T-slots 22 are equidistantly opened on the lower side of the tail beam 2;

[0029] Specifically, the tail beam 2 integrally formed with the extension plate 21 can reduce additional welding or connection processes, improve the integrity and reliability of the overall structure, and greatly increase the structural strength and rigidity. At the same time, the extension plate 21 can form a contact support surface with the main longitudinal beam 1, which can help the main longitudinal beam 1 bear the load, disperse the stress at the welding points of the main longitudinal beam 1, increase the weldable area, and improve the supporting capacity of the structure. The T-slot 22 cooperates with the T-bar 64 on the reinforcement plate 6, so that the reinforcement plate 6 can be fixed on the tail beam 2, and the equidistant arrangement of the T-slots 22 helps to evenly distribute the stress on the tail beam 2.

[0030] Furthermore, a connecting column 4 is inserted on the main longitudinal beam 1 and located between the tail beam 2 and the main cross beam 3. A vertical groove 11 is opened on the main longitudinal beam 1 and located between the tail beam 2 and the main cross beam 3. The connecting column 4 is adapted to the structure of the vertical groove 11.

[0031] Specifically, the connecting column 4 can effectively transfer the load of the tail beam 2 to the main longitudinal beam 1, and also provide additional support and stability for the entire container vehicle end beam structure. The adaptive design of the vertical groove 11 and the connecting column 4 helps to improve the load-bearing capacity and durability of the container vehicle end beam structure, ensuring stability and safety under various transportation conditions.

[0032] Furthermore, an upper baffle 41 is fixedly connected to the top of the connecting column 4, and a circular hole 42 is provided between the two sides of the bottom end of the connecting column 4;

[0033] Specifically, the size of the upper baffle 41 is larger than that of the connecting column 4. The main function of the upper baffle 41 is to provide a limiting function to prevent the connecting column 4 from completely passing through the vertical slot 11, so that the connecting column 4 can be positioned without the aid of bolts and nuts.

[0034] Furthermore, a bearing plate 5 is screwed between the two connecting columns 4, and a plurality of reinforcing plates 6 are installed between the bearing plate 5 and the tail beam 2. Connecting holes 51 are opened at both ends of the bearing plate 5 corresponding to the circular holes 42. A plurality of connecting plates 52 are fixed equidistantly in the middle of the bearing plate 5. A plurality of first assembly holes 53 are opened on both sides of the connecting plate 52 and located on the bearing plate 5.

[0035] Specifically, the load-bearing plate 5 is fixed to the connecting column 4 by bolts and nuts. The corresponding relationship between the connecting hole 51 and the circular hole 42 ensures that the load-bearing plate 5 can be accurately aligned with and fixed to the connecting column 4. It is worth noting that the top wall of the load-bearing plate 5 fits well with the bottom of the main longitudinal beam 1, so that the connecting column 4 connected as a whole with the load-bearing plate 5 will not shake up and down, and the stress can be transmitted to the connecting plate 52 through the load-bearing plate 5.

[0036] Furthermore, a rectangular groove 61 is formed on one side of the reinforcing plate 6 facing the connecting plate 52, and ear plates 62 are fixedly connected to both sides of the reinforcing plate 6, and second assembly holes 63 are formed on the ear plates 62 corresponding to the first assembly holes 53;

[0037] Specifically, the connecting plate 52 is embedded in the rectangular groove 61, so that the reinforcing plate 6 will not fall downward, which can facilitate assembly and avoid stress concentration at the bolt connection point, thereby improving the connection strength of the reinforcing plate 6. The function of the ear plate 62 is to provide an additional connection point so that the reinforcing plate 6 can be screwed to the load-bearing plate 5, thereby improving the stability of the connection.

[0038] Furthermore, the number of the reinforcing plates 6 is the same as the number of the T-slots 22 , and a T-bar 64 is provided on the upper side of each reinforcing plate 6 , and the T-bar 64 is respectively provided through adjacent T-slots 22 ;

[0039] Specifically, T-slots 22 are opened at equal intervals on the lower side of the tail beam 2, and T-bars 64 matching the shape of the T-slots 22 are provided on the upper side of the reinforcing plate 6. When the reinforcing plate 6 is installed in place, the T-bars 64 will be inserted into the corresponding T-slots 22, thereby fixing the reinforcing plate 6 on the tail beam 2. This design not only provides additional support, but also helps to disperse the stress on the tail beam 2, thereby improving the durability and reliability of the entire container vehicle end beam structure.

[0040] Furthermore, the reinforcing plate 6 is in the shape of a right triangle;

[0041] Specifically, a right triangle is a structure that is considered to be very stable in geometry. In the fields of engineering and construction, triangular structures are often used to enhance stability and load-bearing capacity. The right-angled triangle structure of the reinforcement plate 6 helps to improve the stability of the end beam of the container car, especially when bearing vertical and lateral loads. The right-angled triangle reinforcement plate 6 can more effectively disperse and transfer the load. When the tail beam 2 is subjected to a downward force, the right-angled triangle reinforcement plate 6 can transfer the force to a wider base through its hypotenuse, thereby reducing local stress concentration and improving the bearing capacity of the overall structure. Between the tail beam 2 and the load-bearing plate 5, the reinforcement plate 6 can disperse the force to a wider area, reduce stress concentration, and thus reduce the risk of fatigue damage to the structure. The right-angled triangle reinforcement plate 6 can make more effective use of space, especially provide maximum strength and rigidity in a limited space. This design can improve the performance of the container car end beam structure without adding additional materials.

[0042] Working principle:

[0043] During installation, first embed the connecting column 4 into the vertical groove 11, and the upper baffle 41 plays a limiting role, so that the connecting column 4 will not be displaced. Then, fit the bearing plate 5 on the same side of the two connecting columns 4, align the circular hole 42 with the connecting hole 51, insert the bolt, and connect it with the nut after the bolt passes through. After that, align the rectangular groove 61 of the reinforcing plate 6 with the connecting plate 52 and insert it. The T-shaped bar 64 passes through the T-shaped slot 22, so that the first assembly hole 53 and the second assembly hole 63 are aligned with each other. Finally, pass the bolt through the first assembly hole 53 and the second assembly hole 63 and connect the nut.

[0044] When in use, part of the stress acting on the tail beam 2 is vertically supported by the main longitudinal beam 1, and the other part of the stress is transmitted to the load-bearing plate 5 through the reinforcing plate 6, and the load-bearing plate 5 transmits the action to the connecting column 4. Since the connecting column 4 is kept plugged into the main longitudinal beam 1, the main longitudinal beam 1 can longitudinally support the tail beam 2, greatly improving the load-bearing capacity of the container truck end beam.
