[0002] A highway sweeper and wash truck is a special vehicle used to clean roads. It is usually equipped with a high-pressure water gun, a brush, and a garbage storage box. It can clean the dirt and dust on the road and remove the garbage at the same time. Highway sweepers and wash trucks play an important role in road maintenance and cleaning, ensuring the cleanliness and safety of the roads.

[0003] The road anti-collision sweeper and wash truck is equipped with an anti-collision device at the rear of the vehicle, which can build a buffer area between the accident scene or construction site and the anti-collision sweeper and wash truck. The anti-collision device deforms to absorb the energy of the impact, thereby minimizing the damage to personnel and equipment caused by the collision.

[0004] Since the sweeping and washing car has the function of removing garbage, and the garbage is collected and dumped from the rear of the car, the existing anti-collision devices are temporarily installed when they are needed. If they need to be temporarily installed every time, it is inconvenient. If it is necessary to have the functions of garbage removal and anti-collision at the same time, a collision-proof device that can give way must be designed. Therefore, a new type of anti-collision device for road collision-proof sweeping and washing car is proposed. Utility Model Content

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: an anti-collision device for a road anti-collision sweeper and washing vehicle, comprising a fixed frame 2 fixedly installed at the rear of the sweeper and washing vehicle 1, a plurality of through grooves 201 being evenly arranged on the upper surface of the fixed frame 2, the fixed frame 2 can produce a certain energy absorption deformation upon collision, and reduce deformation of the vehicle body, an articulated seat 301 being symmetrically arranged at the rear of the fixed frame 2, and a horizontally arranged yielding movable frame 3 being movably installed on the articulated seat 301 through a pin shaft 302.

[0022] Connecting rings 7 are symmetrically arranged at positions near both sides of the upper surface of the yielding movable frame 3 and at one side of the anti-collision box 4 near the yielding movable frame 3. The two connecting rings 7 on the same side are movably connected by a steel wire safety rope lock 8, which is used to provide safety protection for the anti-collision box 4 to avoid the anti-collision box 4 from flipping outward due to a malfunction of the flipping push rod 5 during the driving of the sweeping and washing vehicle 1, causing a safety hazard. The tail of the yielding movable frame 3 is hinged with the anti-collision box 4, and the two sides of the anti-collision box 4 are vertically fixedly connected with a rotating shaft 9 near the top.

[0023] The surface of the rotating shaft 9 is rotatably connected to a shaft sleeve 904, and the surface of the shaft sleeve 904 is vertically fixedly connected to a telescopic adjustment rod 901. A supporting foot plate 902 is provided at the end of the telescopic adjustment rod 901 away from the shaft sleeve 904, and a ball head seat 903 is provided on the supporting foot plate 902. The telescopic adjustment rod 901 and the ball head seat 903 are rotatably connected to improve the stability of the telescopic adjustment rod 901 in contact with the ground.

[0024] The surface of the sleeve 904 is threadedly connected with a locking bolt 11 that rests on the surface of the rotating shaft 9. When the anti-collision box 4 is flipped open, the telescopic adjustment rod 901 on the rotating shaft 9 can be rotated to make it vertical to the anti-collision box 4 to support the bottom of the anti-collision box 4, thereby improving the service life and failure rate of the flip push rod 5. A flip push rod 5 is arranged at the bottom of the yielding movable frame 3 along the direction of the vehicle body. The end of the flip push rod 5 away from the yielding movable frame 3 is hinged to the bottom of the anti-collision box 4. A yielding push rod 6 is movably installed along the direction of the vehicle body on one side between the fixed frame 2 and the anti-collision box 4 and at the bottom. Buckles 10 are fixedly connected at the positions of the telescopic adjustment rods 901 on both sides of the anti-collision box 4. The telescopic adjustment rods 901 are movably clipped into the inside of the buckles 10 to facilitate the storage and fixation of the telescopic adjustment rods 901.

[0025] Working principle: the flip push rod 5 drives the anti-collision box 4 to flip downward to a horizontal state, and by rotating the telescopic adjustment rod 901 and the supporting foot plate 902 to support it on the ground, the anti-collision function can be achieved through the anti-collision box 4. After use, the flip push rod 5 drives the anti-collision box 4 to flip upward to a vertical state, and the telescopic adjustment rod 901 is clamped by the buckle 10 to complete the storage; when it is necessary to recycle and dump garbage, pull out the pin shaft 302 on one side of the yielding movable frame 3, and the yielding push rod 6 pushes the yielding movable frame 3 and the anti-collision box 4 to flip horizontally to one side of the fixed frame 2, so as to avoid the anti-collision box 4 blocking the garbage recycling and dumping.

[0026] It should be noted that, in this article, terms such as "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.
