[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figure 1-3 The utility model provides a technical solution: a dump truck with a rear door protection device, comprising a truck 1, a double door 2 is provided at the rear end of the truck 1, a support rod 3 is provided at the rear end of the side wall of the truck 1, the number of the support rods 3 is 2 and they are distributed on the left and right sides of the truck 1); a mounting bracket 4 is provided on the front side of the support rod 3, a carrying bracket 5 is provided on the front side of the mounting bracket 4, a telescopic cylinder 6 is provided on the upper end of the carrying bracket 5, and the driving end of the telescopic cylinder 6 extends downward and is provided with a connecting block 7; slide grooves 8 are provided on the four side walls of the support rod 3, and protective plates 9 are slidably provided in the slide grooves 8 on the adjacent surfaces of the support rods 3 on the left and right sides, and the side walls of the protective plates 9 are connected to the connecting block 7, and at the same time, the inner end surface of the protective plate 9 is in contact with the outer end surface of the double door 2.

[0018] Specifically, a connecting rod 10 is provided at the upper end of the left and right support rods 3, and a fixed connecting plate 11 is provided at the inner end of the connecting rod 10 and the support rod 3. End covers are provided on both sides of the connecting rod 10. The connecting rod 10 and the left and right support rods 3 are connected by bolts or welding to ensure sufficient stability between the connecting rod 10 and the left and right support rods 3.

[0019] Specifically, a reinforcement plate 12 is provided at the front end of the connection between the left and right support rods 3 and the connecting rod 10. The reinforcement plate 12 is fixed to the support rod 3 and the connecting rod 10 by fixing bolts to ensure sufficient stability between the support rod 3 and the connecting rod 10.

[0020] Specifically, a reinforcing rib 13 is provided between the fixed connecting plate 11 and the carriage 1 . The provision of the reinforcing rib 13 assists in fixing the fixed connecting plate 11 and the support rod 13 , thereby ensuring that the support rod 3 does not undergo displacement or deformation.

[0021] Specifically, a floating joint 14 is provided between the driving end of the telescopic cylinder 6 and the connecting block 7. The floating joint 14 is equivalent to a coupling, which is used to reduce errors, protect the driving end of the telescopic cylinder 6 and the connecting block 7, extend the service life of the equipment, and connect the driving end of the telescopic cylinder 6 and the two shafts in the connecting block 7 so that it can run smoothly in high-speed and heavy-load power transmission. Some couplings also have the functions of buffering, vibration reduction and improving the dynamic performance of the shaft system. The coupling consists of two halves, which are respectively connected to the driving shaft and the driven shaft. The cylinder floating joint absorbs the eccentricity and lack of parallel accuracy of the connecting parts and the cylinder, so that the cylinder and the connecting parts can also work within the allowable eccentricity range. It is used for the floating joint assembly, so that the cylinder does not need to be centered and the final fine-tuned during installation, eliminating the interference phenomenon caused by the connection error between the two shafts, and can moderately amplify the processing accuracy of the mating parts, meeting the requirements of small size, high anti-position and compressive strength.

[0022] Working principle: When the utility model is working, the protective plate 9 provided can protect the double-opening door 2. Since the protective plate 9 is slidably provided in the slide groove 8 on the adjacent surfaces of the left and right support rods 3, the side wall of the protective plate 9 is connected to the connecting block 7. At the same time, the inner end surface of the protective plate 9 fits with the outer end surface of the double-opening door 2, thereby offsetting the pressure of the cargo on the double-opening door 2, preventing the double-opening door 2 of the carriage 1 from bulging outward, and ensuring that the rear door of the carriage is not deformed.
