[0002] At present, dump trucks generally only have ordinary rear protection at the rear, which cannot protect the traction device. The following situations may occur:

[0003] (1) When using a dump truck, sometimes the sand and gravel are unloaded together as much as possible, and the traction device is exposed to the outside, which may cause the traction device to come into direct contact with the sand and gravel, thus damaging the traction device;

[0004] (2) The traction device is exposed, which may cause additional damage to the rear vehicles and personnel in the event of a rear-end collision. Utility Model Content

[0005] The utility model aims to provide a rear protection structure for protecting a traction device of a dump truck, so as to solve the problems in the background technology.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following further describes how the present invention is implemented in conjunction with the accompanying drawings and specific embodiments.

[0024] See also Figures 1 to 4 The rear protection structure for protecting the traction device of a dump truck provided by the embodiment of the utility model comprises a traction beam 1 for installing the traction device 13 of the dump truck, a traction vertical rib 2 is respectively connected to the left and right ends of the traction beam 1, and the traction vertical rib 2 is used to be connected to the rear end of the dump truck, and a rear protection cross bar 3 is arranged on the front side of the traction beam 1 to protect the traction device 13 of the dump truck, and two rear protection cross bars 4 are arranged on the rear side of the rear protection cross bar 3, and the front ends of the two rear protection cross bars 4 are fixedly connected to the rear protection cross bar 3, and the rear ends are respectively hinged to the two traction vertical ribs 2 arranged at the left and right ends of the traction beam 1 in a one-to-one correspondence, and the rear protection cross bars 4 can drive the rear protection cross bars 3 to rotate up and down, and a tension spring 5 is respectively arranged on the side away from each other of the two traction vertical ribs 2, and one end of each tension spring 5 is connected to a traction vertical rib 2 arranged on the same side, and the other end is connected to a rear protection cross bar 4 arranged on the same side, and the tension spring 5 is used to tie the rear protection cross bar 4.

[0025] Specifically, in the above embodiment, in order to improve the strength of the traction beam 1, a traction beam reinforcement plate 6 is further provided in the middle of the rear side of the traction beam 1, and the traction beam reinforcement plate 6 is connected to the traction beam 1 by bolts.

[0026] Specifically, in the above embodiment, in order to improve the stability of the connection between the traction beam 1 and the traction vertical rib 2, a traction beam reinforcement rib 7 is respectively provided at the left and right ends of the rear side of the traction beam 1, and each of the traction beam reinforcement ribs 7 is fixedly connected to the traction beam 1 and a traction vertical rib 2 provided on the same side.

[0027] Specifically, in the above embodiment, an upper tension spring support 8 is also provided on each traction vertical rib 2, and a lower tension spring support 9 is also provided on each rear protective transverse rib 4. The upper end of each tension spring 5 is connected to the corresponding traction vertical rib 2 through an upper tension spring support 8, and the lower end is connected to the corresponding rear protective transverse rib 4 through a lower tension spring support 9.

[0028] Specifically, in the above embodiment, each rear protective transverse rib 4 is hinged to the corresponding traction vertical rib 2 via a rotating shaft 10 .

[0029] Specifically, in the above embodiment, each rear protective transverse rib 4 is also connected to the corresponding traction vertical rib 2 via a positioning pin shaft 11 .

[0030] More specifically, as a preferred solution of the above embodiment, an arc-shaped positioning hole 12 is provided on each traction vertical rib 2, and the arc-shaped positioning hole 12 is used to connect and cooperate with the positioning pin shaft 11. When the positioning pin shaft 11 is loosened, the positioning pin shaft 11 can slide up and down along the arc-shaped positioning hole 12, so that the rear protection cross rib 4 can move up and down with the rear protection cross bar 3 with the sliding track of the positioning pin shaft 11 as the range in which it can rotate up and down; when the positioning pin shaft 11 is locked, the rear protection cross rib 4 can be locked with the traction vertical rib 2, so that the rear protection cross bar 3 stops moving.

[0031] As some other preferred schemes of the above embodiments, a plurality of arc-shaped circular positioning holes can also be set on each traction vertical rib 2. By changing the connection between the positioning pin shaft 11 and the circular positioning holes at different positions, the fixation of the rear protective transverse rib 4 at different positions can be achieved, thereby achieving the change of the different height positions of the rear protective cross bar 3.

[0032] The working principle of the rear protection structure for protecting the traction device of a dump truck provided in the embodiment of the utility model is as follows:

[0033] When it is necessary to use the dump truck traction device 13, refer to Figure 6 , it is only necessary to move the positioning pin shaft 11 to the lowest end of the arc-shaped positioning hole 12 and lock it. At this time, the rear protective cross bar 3 can completely avoid the dump truck traction device 13, so that the dump truck traction device 13 is in normal use, such as connecting to the rear vehicle.

[0034] When the dump truck traction device 13 is not required, refer to Figure 5 , it is only necessary to move the positioning pin shaft 11 to the uppermost end of the arc-shaped positioning hole 12 and lock it. At this time, the rear protective cross bar 3 will face the front end of the dump truck traction device 13, blocking the front end of the dump truck traction device 13, so that the dump truck traction device 13 is in a non-use state, that is, it plays a protective role for the dump truck traction device 13.

[0035] Finally, it should be noted that the above description is only an embodiment of the present utility model, and does not limit the patent scope of the present utility model. Any equivalent structure or equivalent process transformation made using the contents of the present utility model specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present utility model.
