Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, and in particular to a road roller anti-collision device. Background Technology

[0002] A road roller, also known as a soil compactor, is a type of road construction equipment. In the field of engineering machinery, it falls under the category of road equipment and is widely used for filling and compaction operations in large-scale engineering projects such as highways, railways, airport runways, dams, and stadiums. It can compact sandy, semi-cohesive, and cohesive soils, roadbed stabilized soils, and asphalt concrete pavement layers.

[0003] In road construction, road rollers are indispensable main equipment. The operational safety of road rollers is an important safety indicator for road construction. In order to solve the above-mentioned technical problems, guardrails are often installed on road rollers. Guardrails can separate road rollers from obstacles and effectively prevent construction workers from being run over by the road roller after being hit. However, most existing technologies use fixed guardrails, which will cause wear and tear on the front guardrails when the road roller passes through road surfaces with large height differences.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figures 1 to 3 The road roller anti-collision device shown includes: a bracket 1, a protective plate 2, and a transmission assembly 4. The bracket 1 is installed at both ends of the road roller. The protective plate 2 is slidably connected to the bracket 1 through a sliding assembly 3. The transmission assembly 4 is installed at both ends of the bracket 1 and connected to the protective plate 2. The transmission assembly 4 includes a cylinder 401 vertically installed at both ends of the bracket 1 and a transmission plate 402 connecting the cylinder 401 to the protective plate 2. A laser sensor 5 is also provided at the bottom of the protective plate 2, and a warning system is also provided on the side facing the road ahead.

[0029] The implementation process of this utility model is as follows: When traversing a road surface with a significant height difference, a laser sensor located at the bottom of the protective plate 2 detects the distance between the sensor and the undulating road surface ahead. When the distance falls below the safe level, the control system alerts the driver via a warning light. The driver then controls the cylinder to lift the protective plate, thereby raising it to prevent impact. Once the safe area is reached, the cylinder is lowered. The beneficial effect of this utility model is that the protective plate is designed with an adjustable height via a sliding assembly, preventing damage to the anti-collision device when traversing roads with significant height differences.

[0030] In this utility model, the sliding component 3 includes a slider 301 disposed on the side wall of the bracket 1 and a slide rail 302 disposed on both sides of the protective plate 2. The cooperation between the slide rail 302 and the slider 301 can ensure that the protective plate 2 remains stable during the lifting process, avoiding shaking or jamming. The sliding connection helps to improve the reliability of the entire anti-collision device in operation, ensuring that it can play an effective role under various road conditions.

[0031] As a preferred embodiment, travel limit blocks 6 are provided at both the upper and lower ends of the slide rail 302. The travel limit blocks 6 can accurately limit the lifting range of the protective plate 2 on the slide rail 302. When the protective plate 2 rises to the set highest position or falls to the set lowest position, the travel limit blocks 6 will prevent it from continuing to move, thereby preventing damage to the device or safety hazards caused by excessive lifting. The travel limit blocks 6 can also protect the transmission components (such as cylinders, transmission plates, etc.). When the protective plate 2 reaches the set lifting limit, the travel limit blocks 6 will promptly prevent it from continuing to move, thereby avoiding damage to the transmission components due to excessive force.

[0032] In this invention, the early warning system includes a millimeter-wave ranging radar installed on the side of the protective plate 2 facing the road ahead, and a control system connected to the millimeter-wave ranging radar. The millimeter-wave ranging radar has high-precision ranging capability, enabling it to monitor the distance to obstacles ahead in real time. This high-precision ranging function provides the road roller with more accurate and reliable collision warning information, helping the driver to take timely measures to avoid collisions. The millimeter-wave ranging radar also features rapid response, capable of detecting the presence of obstacles ahead and triggering a warning in a very short time. This rapid response capability helps the driver react quickly in emergency situations, avoiding collisions.

[0033] As a preferred embodiment of the above, the millimeter-wave ranging radar monitors a distance of 20 meters to 0.5 meters. Its monitoring range, from 0.5 meters to 20 meters, covers most of the area in front of the road roller, helping to promptly detect and warn of potential collision risks and providing the driver with more reaction time. In different road construction scenarios, road rollers may need to face various complex environments and obstacles. By setting the monitoring distance from 20 meters to 0.5 meters, the millimeter-wave ranging radar can adapt to different working conditions, ensuring effective collision warnings under various circumstances.

[0034] As a preferred embodiment of the above, the control system is a PLC controller, and a display screen and an alarm 7 are also connected to the PLC controller. The display screen can display the distance information of the obstacle ahead detected by the millimeter-wave ranging radar in real time, as well as the collision warning information processed by the PLC controller. This allows the driver to intuitively understand the road conditions ahead and potential collision risks, thereby making the correct driving decisions. When the millimeter-wave ranging radar detects that the obstacle ahead is too close, it will trigger the alarm to emit an audible and visual alarm signal. The alarm prompt can quickly attract the driver's attention and prompt them to take emergency avoidance measures to avoid the occurrence of a collision.

[0035] As a preferred embodiment of the above, the alarm 7 is installed on the top of both sides of the support 1, which can ensure that the audible and visual alarm signals emitted by the road roller can be more intuitively conveyed to the driver during the operation of the road roller, so that the driver can clearly see and hear the alarm prompts whether in front or from the side, and thus react quickly. The top of both sides of the support 1 is usually located at a higher position of the road roller, so the audible and visual signals emitted by the alarm 7 can cover a wider area, which not only helps to remind the driver, but also warns other construction workers or vehicles in the vicinity to a certain extent, further reducing the risk of collision.

[0036] In this invention, both the laser sensor 5 and the transmission assembly 4 are automatically controlled by the control system. The laser sensor 5 can measure the distance to obstacles in front with high precision and transmit this information to the control system in real time. The control system then uses this information to precisely control the transmission assembly 4, ensuring that the road roller can respond in a timely manner by avoiding obstacles or slowing down, thus effectively preventing collision accidents.

[0037] In this invention, infrared sensors are also provided on the outer sides of both ends of the support 1. These infrared sensors utilize the physical properties of infrared radiation for non-contact measurement, exhibiting high sensitivity and fast response. By capturing invisible infrared radiation, the sensors can monitor environmental changes on both sides of the support 1 in real time, such as the approach of people, vehicles, or other obstacles. The infrared sensors on the outer sides of both ends of the support 1 expand the monitoring range of the collision avoidance warning system, achieving comprehensive coverage of the environment surrounding the road roller. This comprehensive monitoring helps to promptly detect and warn of potential collision risks, providing the driver with more reaction time.

[0038] In this utility model, the protective plate 2 is welded from multiple square steel bars. The multiple square steel bars are connected by welding to form an integral structure. This connection method has high strength and stability. Therefore, the protective plate 2 can withstand greater external impact and is not easily deformed or damaged, thus ensuring its long-term stability and reliability.

[0039] Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
