Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of dump truck body accessories, in particular to a dump truck anti-drilling and rear anti-collision component. Background Art
[0002] Dump trucks are large trucks. Due to their structure, they have a higher body height, and the length of the cargo box on the dump truck body is longer than the body. The bottom of the rear end of the dump truck is empty. Once a small vehicle collides with the rear end, the vehicle's anti-collision beam and front cabin will hardly play any buffering role. The impact force will directly act on the A-pillar, causing major safety accidents. Therefore, it is necessary to install an anti-collision component with good anti-collision effect and excellent protection at the rear end of the dump truck. It can not only protect the dump truck, but also intercept small vehicles that are colliding from the rear to prevent the vehicle from directly drilling under the rear end of the dump truck to ensure the safety of the front and rear vehicles. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a dump truck anti-drilling rear anti-collision component in response to the above-mentioned defects. The component has high structural strength and good anti-collision protection performance. It can prevent the A-pillar of the rear-end collision vehicle from directly colliding with the cargo box, and prevent small vehicles from drilling into the bottom, thus effectively protecting the vehicles in front and behind.
[0004] The technical solution adopted by the utility model to solve its technical problems is as follows: a rear anti-collision component for dump trucks to prevent underrunning, including a first anti-collision column and a second anti-collision column in a vertical downward state, the first anti-collision column and the second anti-collision column are parallel to each other, the rear end surfaces of the first anti-collision column and the second anti-collision column are provided with a support column in an inclined state, an acute angle is formed between the support column and the first anti-collision column and the second anti-collision column, a horizontally arranged upper connecting rod is provided between the first anti-collision column and the second anti-collision column, and a lower portion of the upper connecting rod is provided. A lower connecting rod is provided, and two obliquely arranged diagonal pull rods are symmetrically arranged between the upper connecting rod and the lower connecting rod. The inner walls of the connection between the two oblique pull rods and the upper connecting rod and the lower connecting rod form an isosceles trapezoidal structure. Two first connecting columns are horizontally arranged at the bottom ends of the front ends of the first anti-collision column and the second anti-collision column, and the front ends of the two first connecting columns are provided with lower anti-collision plates. Second connecting columns are symmetrically arranged on the front ends of the first anti-collision column and the second anti-collision column above the first connecting column, and upper anti-collision plates are provided on the front ends of the two second connecting columns.
[0005] Furthermore, the first connecting column and the lower connecting rod are located on the same central axis, and the second connecting column and the upper connecting rod are located on the same central axis.
[0006] Furthermore, an intermediate pull rod is provided between the two oblique pull rods, and the intermediate pull rod is parallel to the upper connecting rod and the lower connecting rod.
[0007] Furthermore, the first anti-collision column and the second anti-collision column are hollow structures, and reinforcement plates with a cross-shaped cross-section are provided inside the first anti-collision column and the second anti-collision column.
[0008] Furthermore, an impact relief device is provided between the upper anti-collision plate, the lower anti-collision plate and the upper connecting rod, the lower connecting rod.
[0009] The cam is secured to the upper and lower ends of the cam, and the cam is secured to the lower ends of the cam, and the cam is secured to the lower ends of the cam.
[0010] The beneficial effects of the utility model are:
[0011] The utility model forms a triangular stable structure through the first anti-collision column, the second anti-collision column, the support column, the upper connecting rod, the lower connecting rod, the oblique pull rod, the first connecting column, the lower anti-collision plate, the second connecting column, the upper anti-collision plate, the support column, the first anti-collision column, the second anti-collision column and the bottom of the vehicle body. After the first anti-collision column and the second anti-collision column are hit, it is not easy to bend and collapse backwards, and can effectively intercept small vehicles to prevent the vehicle from drilling into the bottom of the dump truck. The lower connecting rod, the oblique pull rod and the upper connecting rod cooperate with each other to make the first anti-collision column and the second anti-collision column more integrated. When subjected to external force, the force can be transmitted to multiple places through the lower connecting rod, the oblique pull rod and the upper connecting rod for dispersion. To resist and prevent the situation where a certain place is subjected to greater force, the cooperation of the first connecting column, the lower anti-collision plate, the second connecting column and the upper anti-collision plate leaves a buffer space between the upper and lower anti-collision plates and the first anti-collision column and the second anti-collision column, which can form an impact buffer for the anti-collision beam and the front cabin of the small vehicle, and will not directly act on the first anti-collision column and the second anti-collision column. The upper and lower anti-collision plates increase the protection area and prevent the anti-collision plates from being too high and unable to accurately make the anti-collision beam and the front cabin of the small vehicle work, so that the anti-collision protection performance of the anti-collision component is good, preventing the A-pillar of the rear-end collision vehicle from directly colliding with the cargo box, preventing the small vehicle from drilling into the bottom, and effectively protecting the front and rear vehicles.

[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] Reference Figure 1-4 As shown, the anti-intrusion rear anti-collision component of the dump truck includes a first anti-collision column 1 and a second anti-collision column 2 in a vertical downward state. The first anti-collision column 1 and the second anti-collision column 2 are parallel to each other. The rear end faces of the first anti-collision column 1 and the second anti-collision column 2 are provided with a support column 3 in an inclined state. An acute angle is formed between the support column 3 and the first anti-collision column 1 and the second anti-collision column 2. A triangular stable structure is formed between the first anti-collision column 1 and the second anti-collision column 2, the support column 3 and the bottom of the vehicle. When the first anti-collision column 1 and the second anti-collision column 2 are subjected to external force, the support column 3 provides support and resistance to them, so that the anti-collision column is not easy to bend and collapse to the rear side, which can effectively intercept small vehicles and prevent the vehicles from intruding into the bottom of the dump truck.
[0020] A horizontally arranged upper connecting rod 401 is arranged between the first anti-collision column 1 and the second anti-collision column 2, and a lower connecting rod 402 is arranged below the upper connecting rod 401. The upper connecting rod 401 and the lower connecting rod 402 are parallel to each other, so that the integrity between the first anti-collision column 1 and the second anti-collision column 2 is better, and two obliquely arranged diagonal pull rods 403 are symmetrically arranged between the upper connecting rod 401 and the lower connecting rod 402. The inner wall of the connection between the two diagonal pull rods 403 and the upper connecting rod 401 and the lower connecting rod 402 forms an isosceles trapezoidal structure, and a triangular stable structure is also formed between the diagonal pull rod 403 and the first anti-collision column 1, the second anti-collision column 2, the upper connecting rod 401 and the lower connecting rod 402. The improvement makes the integrity between the first anti-collision column 1, the second anti-collision column 2 and the upper and lower connecting rods better, and the structure is more stable. When subjected to force, it can be dispersed to multiple places for resistance to prevent the occurrence of a situation where a certain place is subjected to greater force.

The anti-collision plates arranged up and down increase the protection area, prevent the anti-collision plates from being too high, and cannot accurately make the anti-collision beam and the front cabin of the small vehicle work, so that the anti-collision protection performance of the anti-collision component is good, prevent the A-pillar of the rear-end collision vehicle from directly colliding with the cargo box, prevent the small vehicle from drilling into the bottom, and effectively protect the front and rear vehicles.
