Description

Technical Field

[0001] This utility model relates to the field of inspection machinery and equipment technology, and in particular to a safety inspection device for construction sites of critical and dangerous projects. Background Technology

[0002] In the field of construction engineering, especially in high-risk sub-projects (referred to as "high-risk projects"), safety inspection is a crucial link in ensuring construction safety. Traditional construction site safety inspection devices are usually mounted on a track system, achieving mobile monitoring through sliding rails. However, such devices still have significant drawbacks in practical applications: conventional devices rely on simple rollers and sliding rails, which are susceptible to vibration and impact in complex construction environments, causing rollers to deviate or even derail, especially at sliding rail joints or curves, posing a risk of inspection equipment jamming or tipping over; existing braking mechanisms mostly use mechanical levers or manual locking methods, requiring manual intervention and making it difficult to achieve rapid braking in emergency situations. While some electromagnetic braking solutions can improve response speed, their complex structures and potential failure risks under power outage or electromagnetic interference scenarios make them unsuitable for high-risk environments. Construction site rails are prone to deformation due to installation errors or long-term loads. The fixed design of traditional braking components struggles to accommodate rail dimensional fluctuations, leading to uneven braking force, accelerated brake pad wear, and even brake failure due to excessive clearance. Frequent braking generates heat buildup, causing brake pad thermal fade. Traditional brake pads are often integral structures with low heat dissipation efficiency, requiring complete replacement after localized wear, resulting in high maintenance costs. Furthermore, the mounting brackets for inspection equipment are often welded, making disassembly and assembly cumbersome and impacting equipment debugging and component replacement efficiency.

[0003] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0021] This utility model provides a safety inspection device for construction sites of high-risk engineering projects. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following detailed description is provided with reference to the accompanying drawings and embodiments. In the description of this utility model, it should be understood that the terms "up," "down," "left," and "right," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description; they should not be construed as limitations on this utility model. Furthermore, the terms "installation," "connection," etc., should be interpreted broadly; those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] Please see Figures 1 to 4 This utility model provides a safety inspection device for construction sites of critical engineering projects, including a mounting frame 1 and mounting brackets 2 symmetrically fixed on both sides of an I-shaped slide rail. It also includes a guide mechanism 3, which comprises a support base 31 located on the inner wall of the mounting bracket 2 and rolling guide wheels 32 that can roll against the I-shaped slide rail; and a braking mechanism 4, comprising symmetrically arranged sliding sleeves 41, a first connecting rod 42 and a second connecting rod 43 that are cross-hinged, an electromagnetic component 6, and a braking component 5. The sliding sleeve 41 is fixed to the mounting bracket 2 and has a retractable braking component 5 inside. The upper ends of the first connecting rod 42 and the second connecting rod 43 are respectively connected to the braking component 5, and their lower ends are linked through the electromagnetic component 6. The electromagnetic component 6 includes an electromagnet 61 and a magnetic guide post 62 that are magnetically attracted to each other, and a compression spring 63 is provided between them. Specifically, the first connecting rod 42 is configured as two parallel rods, and the second connecting rod 43 is located between the two first connecting rods 42 and forms a cross-hinged structure through a rotating shaft. The cross-hinged layout of the double parallel first link 42 and the middle second link 43 enhances the structural rigidity and action synchronization of the link system, avoids jamming caused by uneven force on one side, and ensures smooth and highly consistent braking action.

[0023] Its core principle is as follows: When the electromagnetic component 6 is energized, the electromagnet 61 and the magnetic guide post 62 magnetically attract and close, driving the braking component 5 to open and maintaining the unobstructed state of the slide rail through the linkage structure of the cross-hinged rod. At this time, the compression spring 63 is in an energy-storing compressed state. When the electromagnetic component 6 is de-energized, the magnetic attraction disappears, the compression spring 63 releases its stored potential energy, and pushes the linkage structure to move in the opposite direction, causing the braking component 5 to quickly clamp the slide rail and achieve braking. Through the coordinated cooperation of the electromagnetic component 6 and the cross-hinged rod, the braking mechanism 4 achieves rapid response and reliable operation. The magnetic attraction of the electromagnet 61 and the magnetic guide post 62, combined with the elastic reset characteristic of the compression spring 63, can automatically trigger braking in the event of power failure or emergency, preventing accidental slippage of the inspection device. The cross-hinged rod structure optimizes the braking force transmission path, reduces mechanical impact, adapts to narrow construction environments, and improves the safety and stability of high-altitude track inspection.

[0024] The electromagnetic assembly 6 also includes a support plate 64 fixed to the lower end of the first connecting rod 42, on which the electromagnet 61 is mounted; a fixing plate 65 welded to the lower end of the second connecting rod 43, on which the magnetic guide post 62 is vertically mounted; and the two ends of the compression spring 63 are respectively sleeved around the electromagnet 61 and the magnetic guide post 62. The support plate 64 and the fixing plate 65 respectively fix the electromagnet 61 and the magnetic guide post 62, ensuring precise alignment and avoiding magnetic failure due to misalignment. The compression spring 63 sleeved around the electromagnet 61 and the magnetic guide post 62 further enhances the elastic reset effect, improves the continuity of the electromagnetic assembly 6's operation, and extends its service life. Preferably, a triangular reinforcing rib 66 is provided between the fixing plate 65 and the second connecting rod 43. The added triangular reinforcing rib 66 significantly improves the bending and torsional resistance of the connecting structure. The rigid support of the triangular rib effectively disperses the concentrated stress during braking, preventing the connecting rod from deforming or fatigue-breaking due to long-term alternating loads, and enhancing the structural durability of the braking mechanism 4 under complex working conditions.

[0025] The braking assembly 5 includes a brake rod 51 hinged to the first connecting rod 42 and the second connecting rod 43, and a brake pad 52 located at the end of the brake rod 51 and capable of clamping the I-shaped slide rail. The hinged design of the brake rod 51 and the brake pad 52 makes the braking action more closely conform to the contour of the slide rail, and the clamping force transmitted through the connecting rod is evenly distributed on both sides of the slide rail, avoiding localized wear caused by single-point force. The brake pad 52 directly clamps the I-shaped slide rail, resulting in rapid braking response and controllable braking force, while reducing damage to the slide rail surface and ensuring the reusability of the slide rail.

[0026] The brake pad 52 has a wave-shaped heat dissipation groove on the side facing away from the brake lever 51. This wave-shaped heat dissipation groove increases the heat dissipation area and promotes airflow, effectively reducing the accumulated heat of the brake pad 52 during braking. The wave-shaped structure of the heat dissipation groove also reduces the contact area and lowers the heat conduction efficiency, thereby delaying the degradation of the brake pad 52's material properties due to high temperatures and improving the long-term reliability of the braking system.

[0027] The brake lever 51 consists of an inner rod and an adjusting sleeve fitted onto the outside of the inner rod, with the inner rod and adjusting sleeve connected by a threaded connection. The brake pad 52 is locked to the end of the adjusting sleeve. This threaded connection between the inner rod and the adjusting sleeve allows for fine-tuning of the gap between the brake pad 52 and the slide rail by rotating the adjusting sleeve, facilitating flexible adjustment of the braking force according to wear conditions or operating requirements. This adjustable design extends the service life of the brake pad 52 and the brake lever 51, avoids the maintenance costs of frequent component replacements, and ensures stable braking performance.

[0028] The mounting frame 1 is welded and fixed to the mounting bracket 2 via angle steel plates, and the mounting frame 1 is equipped with a quick-release mounting base 7 for mounting inspection instruments. The angle steel plates are welded and fixed to the mounting frame 1 and the mounting bracket 2, improving the overall connection strength and preventing loosening due to vibration during operation of the inspection device. The quick-release mounting base 7 simplifies the instrument mounting process, allowing for quick equipment replacement without tools, improving inspection efficiency. It is also compatible with various instrument models, enhancing the device's versatility and flexibility. Specifically, the quick-release mounting base 7 can mount various inspection instruments and can also connect to various inspection units via an external support platform, such as an infrared assembly for detecting abnormal surface temperatures or structural thermal stress distribution; an ultrasonic detection module for detecting internal cracks in concrete or welding defects in steel structures; a laser ranging and 3D imaging unit for generating high-precision point cloud models of the construction area in real time; and a gas sensor array for monitoring the concentration of toxic and harmful gases and environmental parameters. Each inspection unit connects to a quick-release base via a standardized interface, supporting hot-swappable replacement. Data can be aggregated to a central control platform via wired or wireless means, enabling multi-source information fusion analysis. Furthermore, the quick-release design is compatible with expansion brackets, allowing the installation of robotic arms, high-definition cameras, or emergency lighting equipment to meet customized inspection needs in different scenarios.

[0029] In summary, this utility model's safety inspection device for construction sites in hazardous engineering projects significantly improves the response speed and operational reliability of the braking mechanism 4 through the coordinated operation of the electromagnetic component 6 and the cross-hinged connecting rod. Utilizing the magnetic attraction of the electromagnet 61 and the magnetic guide post 62, combined with the elastic reset characteristic of the compression spring 63, the opening and closing state of the braking component can be quickly and accurately controlled, achieving automatic emergency braking in the event of power failure or sudden events, effectively preventing accidental slippage of the inspection device. The cross-link structure ensures uniform transmission of braking force, reducing mechanical impact, while its compact overall layout adapts to narrow construction spaces. This design not only enhances the stability and safety of the braking process but also reduces the frequency of manual intervention, making it particularly suitable for complex hazardous engineering scenarios, providing multiple safety guarantees for high-altitude track inspection operations. Therefore, this utility model effectively overcomes the various shortcomings of existing technologies and has high industrial application value.

[0030] It is understood that those skilled in the art can make equivalent substitutions or changes based on the technical solution and inventive concept of this utility model, and all such substitutions or changes should fall within the protection scope of this utility model.
