[0022] Furthermore, in the following description of this utility model, unless otherwise stated, "multiple", "multiple groups", or "multiple roots" means two or more.

[0023] Please see Figure 1-5 The present invention provides a technical solution: a road maintenance vehicle with a protective device. The core of the vehicle is the integration of a multi-functional protective device, which is installed on the main body 1 of the road maintenance vehicle. It can provide all-round safety protection for the vehicle and the surrounding environment during operation, and can be retracted to reduce space occupation when not in operation or driving state, so as to ensure the normal passage of the vehicle.

[0024] The road maintenance vehicle mainly consists of the main body 1 and a multi-functional protective device. The working area of ​​the main body of the road maintenance vehicle is usually located at the rear of the vehicle. The multi-functional protective device integrates three main parts: a front anti-collision component 5 located at the front of the vehicle for anti-collision protection, a side splash protection component 3 located on the roof for preventing injury from side splashes, and a retractable protective net 2 located at the rear of the vehicle for isolating the working area to prevent personnel from accidentally entering.

[0025] The side splash protection component 3 is used to expand to the front and rear sides of the vehicle during operation, forming a physical barrier to block stones, high-temperature asphalt, etc., splashed from the work area, protecting pedestrians, vehicles, or facilities nearby. The side splash protection component 3 includes two parallel first sleeves 31, which are fixedly installed longitudinally on the left and right sides of the top surface of the road maintenance vehicle body 1 along the width direction of the vehicle's top surface. A set of baffle components 32 is provided in both the front and rear directions of the vehicle. The inner end of each baffle component 32, that is, the end closer to the center of the vehicle, slides into the ends of the two first sleeves 31 on the same side. The front baffle is inserted into the front port, and the rear baffle is inserted into the rear port, so that the baffle component 32 can extend and retract along the sleeve. At the front and rear ends of the top surface of each first sleeve 31, a first limiting bolt 33 is screwed. When the baffle component 32 is pulled out to the required extension position, the corresponding first limiting bolt 33 is tightened so that its lower end tightly abuts against the top surface of the baffle component 32 part inserted into the sleeve, which can securely lock it and prevent it from retracting or shaking during operation.

[0026] Specifically, each baffle assembly 32 consists of two parallel first L-shaped rods 321 and a baffle 322 fixed between the longitudinal portions of the two first L-shaped rods 321. The transverse portion of the first L-shaped rods 321 is inserted into the first sleeve 31 as a sliding rod, and the longitudinal portion is used to support the baffle 322.

[0027] The telescopic protective net 2 is used to unfold when working at the rear of the vehicle to form a rear protective area to prevent unauthorized personnel from accidentally entering the dangerous work area. The telescopic protective net 2 includes two parallel second sleeves 21, which are horizontally embedded and fixed to the front and rear sides of the rear wall of the road maintenance vehicle body 1 along the length of the vehicle body. The horizontal parts of two second L-shaped rods 22 are slidably inserted into the front and rear second sleeves 21 respectively. A mesh plate 24 is fixedly connected between the longitudinal parts of the two second L-shaped rods 22. By pushing and pulling the second L-shaped rods 22, the mesh plate 24 can be unfolded or retracted. To ensure that the protective net can withstand a certain external impact after unfolding, a special limiting structure is set. On the opposite surface of the horizontal part of the front and rear second L-shaped rods 22, a first sliding groove 231 along its length direction is opened. The two ends of a crossbeam 232 are slidably embedded in these two first sliding grooves 231 respectively. On the left and right sides of the horizontal part of each second L-shaped rod 22, a threaded through hole 233 is opened.

[0028] When the protective net needs to be deployed, pull the second L-shaped rod 22 out of the sleeve. When the protective net is fully deployed, slide the crossbeam 232 to the left end of the first slide groove 231, and screw the second limiting bolt 234 into the threaded through hole 233 on the left side so that its lower end is pressed against the top surface of the crossbeam 232. Thus, the crossbeam 232 is used to firmly lock the two deployed second L-shaped rods 22, forming a stable support frame and preventing the second L-shaped rods 22 from retracting into the second sleeve 21. When the protective net is retracted, push the crossbeam 232 to the right end of the first slide groove 231 and lock it with the second limiting bolt 234 on the right side to prevent the crossbeam 232 from obstructing the retraction of the second L-shaped rods 22. Securely place the second limiting bolt 234 for easy continued use. More specifically, when the protective net is retracted, the second L-shaped rod can be attached and fixed to the outer wall of the road maintenance vehicle body 1 by means of rope binding or adding magnetic adsorption blocks to prevent it from extending accidentally.

[0029] The front bumper 5 is used to protect the front of the vehicle. In the event of a minor collision, it absorbs energy through a buffer structure to reduce damage. The front bumper 5 includes a base plate 51 fixed to the front wall of the road maintenance vehicle body 1. A vertical guide plate 52 and an arc-shaped plate 53 with its convex surface facing outward are fixed at the front and rear ends of the base plate 51. The arc-shaped plate 53 is slidably connected to the front and rear guide plates 52 through its two ends. Specifically, it is achieved through a sliding guide structure 54: a second transverse groove 541 is opened on the inner side of the guide plate 52, and sliders 542 are fixed at both ends of the arc-shaped plate 53. Embedded in the corresponding second sliding groove 541 and able to slide left and right, multiple damping buffers 55 are evenly arranged in the horizontal direction between the arc plate 53 and the base plate 51. Each damping buffer 55 includes a damping telescopic rod 551 and a spring 552 sleeved on its outside. The two ends of the damping telescopic rod 551 are fixed on the arc plate 53 and the base plate 51 respectively, and the two ends of the spring 552 abut against the two respectively. When the arc plate 53 is impacted from the front, it will compress the spring 552 inward and drive the damping telescopic rod 551 to contract, thereby buffering and absorbing the impact force.

[0030] To facilitate operators accessing the side splash protection component 3 from the roof, a ladder 4 is fixedly installed on the outer wall of the main body 1 of the road maintenance vehicle.

[0031] After the vehicle arrives at the work site, the operator climbs onto the roof via ladder 4, pulls the front and rear baffle assemblies 32 out of the first sleeve 31 to the appropriate position, and locks them with the first limiting bolt 33. Then, the two second L-shaped rods 22 are pulled out at the rear of the vehicle, so that the mesh panel 24 unfolds behind the work area and is locked by extending the rear limiting structure 23. The unfolded side baffles 322 can effectively block side splashes; the unfolded rear mesh panel 24 can warn and prevent personnel from entering; the front arc-shaped plate 53 is always in a standby protective state.

[0032] After the operation is completed, loosen all the limit bolts, push the baffle assembly 32 back to the first sleeve 31, and push the second L-shaped rod 22 back to the second sleeve 21, so that all the extended parts are close to the vehicle body, which greatly reduces the vehicle's external dimensions and facilitates safe driving and transfer. Through the above-mentioned integrated multi-functional protective device, 360-degree safety protection is achieved for the road maintenance vehicle during operation, while also taking into account the convenience of vehicle driving, effectively improving the safety of operation and the practicality of the vehicle.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
