Description

Technical Field

[0001] This utility model relates to the field of dump truck technology, and in particular to a protective crossbar cover structure for dump trucks. Background Technology

[0002] A dump truck is a vehicle that unloads goods by hydraulic or mechanical lifting; it is also known as a tipper truck. It mainly consists of a truck chassis, a hydraulic lifting mechanism, a cargo box, and a power take-off unit. Dump truck cargo boxes can be divided into two types: rear-tipping and side-tipping. Rear-tipping is more common. The rear-tipping method involves controlling a piston rod through a control system to tilt the cargo box.

[0003] To reduce the vehicle's weight, the rear protective crossbars of dump trucks are generally made of hollow steel pipes. Traditionally, the rear protective crossbars of dump trucks are sealed at both ends of the hollow steel pipes by welding steel plates. This process is cumbersome and may result in welding defects that affect the product's appearance. In addition, the welded steel plates are relatively heavy.

[0004] Therefore, a protective crossbar cover structure for dump trucks is needed to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model addresses the technical problems existing in the prior art by providing a protective crossbar cover structure for dump trucks.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A protective crossbar plug structure for dump trucks includes an end cap and a protective crossbar. The protective crossbar is a hollow structure. The end cap includes an end cap body. A connecting cylinder is vertically connected to one side of the end cap body. The cross-section of the connecting cylinder has the same shape as the end face of the protective crossbar. Multiple wedge-shaped retaining strips are provided on the outer side of the connecting cylinder. The connecting cylinder is inserted into the end of the protective crossbar. The wedge-shaped retaining strips abut against the inner wall of the protective crossbar.

[0007] Preferably, in the above-mentioned dump truck protective crossbar cover structure, the inner side of the end cover body is provided with reinforcing ribs.

[0026] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0027] like Figures 1-3 As shown, a protective crossbar cover structure for a dump truck includes an end cap 3 and a protective crossbar 2. The protective crossbar 2 is a hollow structure and is fixedly connected to the vertical beam 1 of the balance beam.

[0028] The end cap 3 includes an end cap body 31, with a connecting cylinder 32 vertically connected to one side of the end cap body 31. The cross-section of the connecting cylinder 32 has the same shape as the end face of the protective crossbar 2, preferably both being rectangular cylinders. Multiple wedge-shaped retaining strips 33 are provided on the outer surface of the connecting cylinder 32. The connecting cylinder 32 is inserted into the end of the protective crossbar 2. One side of the wedge-shaped retaining strip 33 near the end cap body 31 is perpendicular to the outer surface of the connecting cylinder 32, while the other side is inclined, facilitating the insertion of the connecting cylinder 32 into the end of the protective crossbar 2 and preventing reverse movement while locking it inside. After the connecting cylinder 32 is inserted into the protective crossbar 2, the wedge-shaped retaining strip 33 abuts against the inner wall of the protective crossbar 2. The end cap body 31, connecting cylinder 32, and wedge-shaped retaining strip 33 are all made of plastic and are integrally molded. They are inserted into both ends of the protective crossbar through assembly, utilizing the plasticity of the material itself for elastic clamping. Furthermore, when working conditions are poor, holes can be drilled in the protective crossbar 2 to add screws, which can be used to further tighten the connecting cylinder 32 to prevent it from loosening. Reinforcing ribs 34 are provided on the inner side of the end cap body 31 to improve the structural strength of the end cap.

[0029] Because the end cap 3 is difficult to remove after assembly, it is usually difficult to remove when necessary. For example, if the end cap 3 is damaged and needs to be replaced, or if it is necessary to operate inside the protective crossbar 2, it is usually necessary to forcibly break it to remove it when it is difficult to remove the end cap 3. However, this method is prone to damaging the end of the protective crossbar 2. Therefore, the following embodiments further improve the structure of the end cap.

[0030] like Figures 4-6As shown, a countersunk hole 38 is provided at the center of the end cap body 31, and a pull cap 37 is installed in the countersunk hole 38. Multiple pull ropes 36, preferably eight, are connected between the pull cap 37 and the connecting cylinder 32, with two ropes connected to each side of the connecting cylinder 32. One end of the pull cap 37 is provided with a rope-tying protrusion 39, and one end of the pull rope 36 is fixed to the rope-tying protrusion 39. The other end of the pull rope 36 is fixedly connected to the end of the connecting cylinder 32. A rope-passing hole can be reserved at the end of the connecting cylinder 32 to fix the pull rope 36. In order to change the direction of the force applied by the pull rope to the end of the connecting cylinder 32, so as to facilitate pulling the end of the connecting cylinder 32 inward, a pull rope bending cylinder 35 is vertically provided on the inner side of the end cap body 31. The pull rope 36 passes through the pull rope bending cylinder 35, and the pull rope bending cylinder 35 pushes the pull rope, so that the pull rope 36 is bent in a taut state. After the pull cover 37 is installed into the countersunk hole 38, the two are fixed by interference fit using the elasticity between the plastics, and the outer end face of the pull cover 37 is flush with the outer end face of the end cover body 31. After the pull cover 37 is installed into the countersunk hole 38, each pull rope still has room for stretching, which makes it easy to remove the pull cover 37. This can be achieved by increasing the length of the pull rope or by using elastic rope.

[0031] Furthermore, a gap is left between the pull cap 37 and the inner side wall of the outer end of the countersunk hole 38, so that the pull cap 37 can be pried out through the gap when it is removed.

[0032] When it is necessary to remove the end cap 3, first remove the pull cap 37, and then pull the pull cap 37 outward. As the side wall of the connecting cylinder 32 moves inward, the pressure between the wedge-shaped locking strip 33 and the inner wall of the protective crossbar 2 is reduced, thereby reducing the friction between the two, and thus the end cap 3 can be easily removed from the protective crossbar 2.
