Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, specifically to a reinforced safety strut structure for preventing the dump truck bed from falling down. Background Technology

[0002] like Figure 1 As shown, the existing safety strut structure 100 for preventing the dump truck body from falling is usually a simple single-strut structure, which is connected to both sides of the longitudinal beam 200 of the lower frame of the truck body by a pin. When dealing with the huge impact force generated by the sudden fall of the truck body due to a malfunction, its support strength and stability are limited, and it is easy to deform or even break, which cannot effectively ensure the safety of operation. Utility Model Content

[0003] The purpose of this utility model is to provide a reinforced safety strut structure for preventing the dump truck body from falling down, in order to solve the technical problems existing in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A reinforced safety strut structure for preventing the dump truck body from falling down includes two parallel and opposite safety strut main rods and an inner connecting rod of the safety struts disposed between the two parallel and opposite safety strut main rods. Each safety strut main rod has a pair of safety strut seat plates at one end and a safety strut pad plate at the other end; wherein, the upper part of each pair of safety strut seat plates is arc-shaped.

[0006] Furthermore, each pair of safety strut seat plates is fixed to the left and right sides of the corresponding safety strut main rod at the end away from the safety strut pad by a pin.

[0007] Furthermore, each pair of safety strut seat plates includes two safety strut seat plates, and the two safety strut seat plates are symmetrically arranged on the left and right sides of the corresponding safety strut main rod, and are fastened together with the corresponding safety strut main rod by pins and cotter pins.

[0008] Furthermore, each of the aforementioned safety strut base plates includes a vertical base plate portion and a horizontal base plate portion. The horizontal base plate portion is located on one side of the upper end of the vertical base plate portion and is used to connect with the crossbeam of the lower frame of the carriage. The other side of the upper end of the vertical base plate portion is arc-shaped, and the lower end of the vertical base plate portion is connected to the reinforcing plate of the crossbeam of the lower frame of the carriage.

[0009] Furthermore, the main strut of the safety support rod is made of square or round tubing.

[0010] Furthermore, the inner connecting rod of the safety strut is made of square or round tubing.

[0011] Furthermore, the safety strut pad is made of a flat plate or a U-shaped groove plate.

[0012] Furthermore, the main rod of the safety strut, the inner connecting rod of the safety strut, the seat plate of the safety strut, and the pad plate of the safety strut are all made of metal.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] (1) By designing the upper part of the safety strut seat plate into an arc shape, the external force can be evenly distributed. When subjected to external impact or pressure, the arc shape can distribute the force to other parts, reduce the risk of damage caused by stress concentration, and extend the service life. It can better bear and transmit the load, improve the overall load-bearing performance of the seat plate, and ensure that it is more stable and reliable when bearing the relevant forces of the safety strut.

[0015] (2) By welding the upper part of the safety strut base plate to the crossbeam of the lower frame of the carriage and the lower part to the reinforcing plate of the crossbeam of the lower frame of the carriage, multiple stress points are formed, which improves the support strength of the entire safety strut.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0027] The present invention will be further described below with reference to the accompanying drawings:

[0028] See Figures 2 to 7 This invention illustrates a specific embodiment of a reinforced safety strut structure for preventing the dump truck body from falling down, comprising two parallel and opposite safety strut main rods 1 and an inner connecting rod 2 of the safety struts disposed between the two parallel and opposite safety strut main rods 1. Each safety strut main rod 1 has a pair of safety strut seat plates 3 at one end and a safety strut pad plate 4 at the other end; wherein the upper part of each pair of safety strut seat plates 3 is arc-shaped.

[0029] Please continue reading. Figures 2 to 7 In some specific embodiments, each pair of safety strut seat plates 3 is fixed to the left and right sides of the corresponding safety strut main rod 1 at the end away from the safety strut pad plate 4 by means of pins 5.

[0030] Please continue reading. Figures 2 to 7In the specific embodiment shown, each pair of safety strut base plates 3 includes two safety strut base plates 3, and the two safety strut base plates 3 are symmetrically arranged on the left and right sides of the corresponding safety strut main rod 1, and are fastened together with the corresponding safety strut main rod 1 by a pin 5 and a cotter pin 6. It should be noted that the connection between the pin 5 and the cotter pin 6 is prior art, that is, the pin 5 is provided with a corresponding cotter pin mounting hole, and the cotter pin 6 is installed in this cotter pin mounting hole to achieve the fastening of the safety strut base plate 3 and the safety strut main rod 1 by means of the pin 5 and the cotter pin 6. Furthermore, a washer 7 is also provided at the end of the pin 5 where the cotter pin 6 is installed, and the washer 7 is used to prevent wear of the cotter pin 6.

[0031] Specifically, see Figure 2 , Figures 5 to 7 In the specific embodiment shown, each safety strut seat plate 3 includes a vertical portion 301 and a horizontal portion 302. The horizontal portion 302 is located on one side of the upper end of the vertical portion 301 and is used to connect with the crossbeam 100 of the lower frame of the carriage. The other side of the upper end of the vertical portion 301 is arc-shaped, and the lower end of the vertical portion 301 is connected to the reinforcing plate 200 of the crossbeam of the lower frame of the carriage. By designing the side of the upper end of the vertical portion 301 away from the horizontal portion 302 as arc-shaped, it can evenly distribute external forces. When subjected to external impact or pressure (i.e., the huge impact force generated by the sudden drop of the carriage due to a malfunction), the arc shape can distribute the force to other parts, reducing the risk of damage caused by stress concentration and extending the service life. It can also better bear and transmit loads, improve the overall load-bearing capacity of the safety strut seat plate 3, and ensure greater stability and reliability when subjected to relevant forces.

[0032] Specifically, in the illustrated embodiment, the main safety strut 1 is made of a square tube. It is understood that the square tube includes both rectangular and square tubes; in the illustrated embodiment, the main safety strut 1 is specifically made of a rectangular tube. Furthermore, in some other embodiments, the main safety strut 1 may be made of a round tube.

[0033] Specifically, in the illustrated embodiment, the inner connecting rod 2 of the safety strut is made of a round tube. In some other embodiments, the main rod 1 of the safety strut can be made of a square tube, such as a rectangular tube.

[0034] Specifically, in the illustrated embodiment, the safety strut pad 4 is made of a U-shaped groove plate. In some other embodiments, the safety strut pad 4 may be made of a flat plate.

[0035] Specifically, in this utility model, the main rod 1 of the safety support rod, the inner connecting rod 2 of the safety support rod, the seat plate 3 of the safety support rod, and the pad plate 4 of the safety support rod are all made of metal, such as aluminum alloy, stainless steel, or cast iron.

[0036] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
