Description

Technical Field

[0001] The present invention belongs to the technical field of column anti-collision, and more specifically, relates to a column anti-collision detection and early warning device and method for foundation backfill construction. Background Art

[0002] In foundation backfill construction, the development of an efficient column anti-collision detection and early warning device is crucial to improving construction safety. With the rapid development of the economy and the acceleration of urbanization, earthwork backfill construction plays an increasingly important role in infrastructure construction. However, due to the complex environment of the construction site, the frequent movement of machinery and vehicles, and the operator's blind spots and human errors, the risk of collision accidents during construction increases. These accidents not only threaten the lives of workers, but may also cause damage to construction equipment, project delays and economic losses. Therefore, an efficient column anti-collision detection and early warning device is proposed, which can monitor the surrounding environment in real time and send out early warning signals in time, thereby avoiding or reducing the occurrence of collision accidents, which is particularly important for construction safety.

[0003] In order to solve the above technical problems, Chinese invention patent CN116206487A discloses a column anti-collision warning system and method, the system includes: sensor equipment, control equipment and alarm equipment; the sensor equipment is used to detect the distance and transmit the step signal generated by the detection to the control equipment; the control equipment is used to generate warning judgment start information when the step signal is greater than the preset height, and generate a warning instruction according to the warning judgment start information; the alarm equipment is used to issue a warning prompt according to the warning instruction. Since the column anti-collision warning system of the present invention determines whether to issue a warning instruction by judging the step signal monitored by the sensor through the control equipment, the column anti-collision warning is performed by an intelligent column anti-collision warning system, which reduces the steps of manual operation and prevents false alarms caused by manual factors and increased material layer thickness during material unloading. In addition, Chinese utility model patent CN215977845U discloses a reinforced concrete column anti-collision system with a viscous damper, including a reinforced concrete column, a baffle, a spring, an embedded part, a viscous damper, and a reserved hole. The viscous damper is installed in the reserved hole on the reinforced concrete column and connected to the baffle through the steel bar by welding. The springs set at the upper and lower ends of the baffle are connected to the reinforced concrete column through embedded parts. It has a simple structure and is easy to make. It can improve the anti-collision ability of the column and reduce the impact of the collision on the column.

[0004] The above patent technology avoids the risk of collision to a certain extent by taking early warning measures, but there are still the following technical problems or room for improvement: (1) The technical solution disclosed in CN215977845U modifies the column body, which greatly affects the strength characteristics of the main body itself and is extremely disadvantageous in the construction field; (2) Due to the complex and changeable conditions at the construction site, the line of sight is easily blocked and the sound is chaotic, but the early warning means adopted by the above patent technology are relatively single and cannot improve the effectiveness of the warning more comprehensively; (3) Based on the above technical problems, the structural solution should be optimized as much as possible from the perspective of ease of use and functional integrity of the device.

[0076] In an embodiment of the present invention, the secondary anti-collision unit is implemented by an infrared beaming method. Infrared beaming heads are provided on the surfaces of the outriggers of the bottom positioning frame 210 and the top positioning frame 220.

[0080] The working principle of the embodiment of the present invention is as follows: first, the mother cross frame assembly and the male cross frame assembly are placed on the surface of the concrete column 1, and inserted into a tic-tac-toe structure, and installed closely to the side of the concrete column 1, and the tic-tac-toe structure is kept stable by the fixing screw 213; then, only the fixing screw 213 of the bottom positioning frame 210 is pressed tightly against the surface of the concrete column 1, and the fixing screw 213 in the top positioning frame 220 is only used to keep the tic-tac-toe structure stable; then, the crawling and lifting unit 3 at the bottom of the top positioning frame 220 is controlled to start, and after the top positioning frame 220 is driven to climb up to the target height, the height locking assembly 320 is started, so that the locking drive motor 323 drives the locking drive gear to rotate, and then under the transmission action of the locking drive rack part, the second shell 3200 is extended forward, so that the active walking wheel and the driven walking wheel together with the bearing slider 311 are pressed into the internal slide groove of the second shell 3200, and finally the front end of the second shell 3200 directly abuts against the surface of the concrete column 1. Thereby achieving height locking; then, with the help of the alignment drive component 510, the infrared beam component 520 is extended to the same horizontal position, and the continuity of the infrared beam is detected. If the infrared beam is successful at this time, it means that the column itself is vertical. If the infrared beam fails at this time, it means that the column itself is tilted. At this time, adjust the alignment drive component 510 again until the infrared beam component 520 successfully shoots, and then the inclination of the column is reversed by the extension amount to determine whether the inclination of the column is within the safe range. At this point, the preliminary installation preparation of the device is completed; then, in the first-level anti-collision unit, the sensing range of the photoelectric sensor probe 410 is relatively far. When an object invades, it can be sensed by it. At this time, the sound alarm is activated to sound a first-level sound alarm. In the second-level anti-collision unit, when the infrared beam component senses the invasion of foreign objects, a stronger jet and sound alarm are activated to further remind construction personnel to pay attention to construction safety.

[0081] like Fig.10 As shown, in an embodiment of the present invention, a method for using a column anti-collision detection and warning device for foundation backfill construction includes the following steps:
