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 warning device is crucial for improving construction safety. With the rapid economic development and accelerated urbanization, earthwork backfill construction plays an increasingly important role in infrastructure construction. However, due to the complex construction site environment, the frequent movement of machinery and vehicles, and the operator's blind spots and human error, the risk of collision accidents during construction increases. These accidents not only threaten the lives of workers but can also lead to damage to construction equipment, project delays, and economic losses. Therefore, a highly efficient column anti-collision detection and warning device is proposed. This device can monitor the surrounding environment in real time and issue timely warning signals, thereby avoiding or reducing the occurrence of collision accidents. This is particularly important for construction safety.

[0003] To address the above-mentioned technical issues, Chinese invention patent CN116206487A discloses a column anti-collision warning system and method. The system comprises: a sensor device, a control device, and an alarm device. The sensor device is configured to detect distance and transmit a step signal generated by the detection to the control device. The control device is configured to generate a warning determination activation message when the step signal exceeds a preset height, and to generate a warning instruction based on the warning determination activation message. The alarm device is configured to issue a warning prompt based on the warning instruction. Because the column anti-collision warning system of the present invention uses the control device to determine whether to issue a warning instruction based on the step signal detected by the sensor, an intelligent column anti-collision warning system provides column anti-collision warnings, reducing manual operation steps and preventing false alarms caused by human factors and increased material thickness during material unloading. Furthermore, Chinese utility model patent CN215977845U discloses a reinforced concrete column anti-collision system with a viscous damper, comprising a reinforced concrete column, a baffle, a spring, embedded parts, a viscous damper, and a reserved hole. The viscous damper is installed in a pre-reserved hole in the reinforced concrete column and connected to the baffle by welding through the steel bars. Springs at the upper and lower ends of the baffle are connected to the reinforced concrete column via embedded components. Its simple structure and ease of fabrication improve the column's anti-collision capabilities and mitigate the impact of collisions.

[0004] The above patented technology avoids the risk of collision to a certain extent by taking early warning measures, but there are still the following technical problems or areas 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) Since the conditions at the construction site are complex and changeable, and the line of sight is easily blocked and the sound is chaotic, the early warning means adopted by the above patented technology are relatively simple and cannot more comprehensively improve the effectiveness of the warning; (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. Summary of the Invention

[0005] In response to the above-mentioned defects or improvement needs of the prior art, the present invention provides a column anti-collision detection and warning device for foundation backfill construction. Based on a detachable crisscross frame main structure, a secondary detection and warning unit with different response intensity levels is designed, which effectively solves the technical problem that the prior art cannot more comprehensively improve the warning effectiveness due to the complex and changeable conditions at the construction site, the easy obstruction of vision, and the chaotic sound. In addition, the present invention adopts a column surface clamping method without making any modification to the column itself, thereby ensuring the original strength of the column. And by adding functions such as automatic balancing climbing and height position locking, the overall structural scheme is optimized from the perspective of device ease of use and functional integrity.

[0018] A gyroscope is fixed to the first housing.

[0019] Preferably, the height locking assembly comprises:

[0020] A locking drive rack portion is arranged on one side of the second shell, a locking drive motor is fixed to the first shell, and a locking drive gear is coaxially fixedly connected to the output shaft of the locking drive motor and is meshed with the locking drive rack portion.

[0029] According to a second aspect of the present invention, a method for using a column anti-collision detection and warning device for foundation backfill construction includes the following steps:

[0030] S100: Place the parent cross frame assembly and the male cross frame assembly on the surface of the concrete column, insert them into a well-shaped structure, install them close to the side of the concrete column, and use the tightening screws to keep the well-shaped structure stable;

[0031] S200: Only the fixing screws of the bottom positioning frame are pressed tightly against the surface of the concrete column, while the fixing screws in the top positioning frame are only used to maintain the stability of the well-shaped structure;

[0032] S300: Control and start the crawling and lifting unit at the bottom of the top positioning frame, drive the top positioning frame to climb up to the target height, and then start the height locking component, so that the locking drive motor drives the locking drive gear to rotate, and then under the transmission action of the locking drive rack, the second shell is extended forward, thereby pressing the active and driven running wheels together with the load-bearing slider into the internal sliding groove of the second shell, and finally making the front end of the second shell directly abut the surface of the concrete column, thereby achieving height locking;

[0033] S400: Using the alignment drive assembly, the infrared beam assembly is extended to the same horizontal position and the continuity of the infrared beam is tested. If the infrared beam is successful, it indicates that the column itself is vertical. If the infrared beam fails, it indicates that the column itself is tilted. At this time, the alignment drive assembly is adjusted again until the infrared beam assembly successfully transmits the beam. The column tilt is then inversely calculated based on the extension amount to determine whether the column tilt is within a safe range. This completes the preliminary installation preparation of the device.

[0034] S500: In the first-level anti-collision unit, the sensing range of the photoelectric sensor probe is relatively far. When an object intrudes, 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 counter-radiation component senses the intrusion of foreign objects, a stronger jet and sound alarm are activated to further remind construction workers to pay attention to construction safety.

[0035] In general, the above technical solutions conceived by the present invention can achieve the following beneficial effects compared with the prior art:

[0036] 1. The present invention utilizes a column anti-collision detection and warning device for foundation backfill construction. Based on a removable, crisscross-shaped frame structure, it incorporates two detection and warning units with varying levels of response intensity. This effectively addresses the technical limitations of existing technologies, which hinder the comprehensive improvement of warning effectiveness due to complex and changing conditions at construction sites, obstructed vision, and chaotic sound. Furthermore, the present invention utilizes a column surface clamping method, without modifying the column itself, thus preserving its inherent strength. Furthermore, the addition of automatic balancing climbing and height position locking functions optimizes the overall structural design from the perspectives of ease of use and functional integrity.

[0037] 2. The present invention relates to a column anti-collision detection and early warning device for foundation backfill construction. The secondary anti-collision unit is implemented using an infrared beaming method. Infrared beaming heads are provided on the outrigger surfaces of both the bottom and top positioning frames. Through beaming from the top and bottom positions, the column surface can accurately sense foreign object intrusion at close range. Furthermore, the present invention incorporates a magnetically driven alignment drive assembly to horizontally adjust the position of the infrared beaming heads. This not only solves the technical problem of infrared beam misalignment caused by column tilt, but also allows for measurement and calculation of the column inclination through the adjustment amount. Furthermore, the magnetic isolation and propulsion method also provides a certain degree of waterproofing.

[0038] 3. The present invention provides a column anti-collision detection and warning device for foundation backfill construction. The secondary anti-collision unit is implemented by jet, which can more effectively and directly affect the construction personnel and remind them to construct safely. In addition, the present invention only installs the jet alarm to the bottom positioning frame, ensuring the convenience of laying and dragging the water pipes; and installs the sound alarm to the top positioning frame, thereby achieving sound diffusion in a wider range.

[0078] The jet alarm 540 is fixed to the bottom positioning frame 210 , and the sound alarm 420 is fixed to 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 well-shaped structure, tightly installed to the side of the concrete column 1, and the well-shaped 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 well-shaped 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 climbs 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, the second shell 3200 is extended forward, thereby pressing the active walking wheel and the driven walking wheel together with the bearing slider 311 into the internal slide groove of the second shell 3200, and finally making the front end of the second shell 3200 directly abut the surface of the concrete column 1. Thereby achieving height locking; then, with the help of the alignment drive component 510, the infrared radiation component 520 is extended to the same horizontal position, and the continuity of the infrared radiation is detected. If the infrared radiation is successful at this time, it means that the column itself is vertical. If the infrared radiation 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 radiation component 520 successfully shoots, and then reversely solve the inclination of the column through the extension amount to determine whether the inclination of the column is within the safe range. 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 intrudes, 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 radiation component senses the intrusion of foreign objects, it activates a more powerful jet and sound alarm to further remind construction personnel to pay attention to construction safety.

[0081] like Figure 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:

[0082] S100: Place the female cross frame assembly and the male cross frame assembly on the surface of the concrete column 1, insert them into a well-shaped structure, install them closely to the side of the concrete column 1, and use the fixing screws 213 to keep the well-shaped structure stable;

[0083] S200: Only the fastening screws 213 of the bottom positioning frame 210 are pressed tightly against the surface of the concrete column 1, while the fastening screws 213 in the top positioning frame 220 are only used to maintain the stability of the crisscross structure;

[0084] S300: Control and start the crawling and lifting unit 3 at the bottom of the top positioning frame 220, drive the top positioning frame 220 to climb up to the target height, and then start the height locking component 320, 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, the second shell 3200 is extended forward, so that the active and driven running wheels together with the bearing slider 311 are pressed into the internal sliding groove of the second shell 3200, and finally the front end of the second shell 3200 directly abuts the surface of the concrete column 1, thereby achieving height locking;

[0085] S400: Using the alignment drive assembly 510, the infrared beam assembly 520 is extended to the same horizontal position, and the continuity of the infrared beam is tested. If the infrared beam is successful, it means that the column itself is vertical. If the infrared beam fails, it means that the column itself is tilted. At this time, the alignment drive assembly 510 is adjusted again until the infrared beam assembly 520 successfully emits the beam. Then, the inclination of the column is reversed based on the extension amount to determine whether the inclination of the column is within a safe range. This completes the preliminary installation preparation of the device;

[0086] S500: 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 counter-radiation component senses the invasion of foreign objects, a more powerful jet and sound alarm are activated to further remind construction workers to pay attention to construction safety.
