The application provides a manhole anti-falling net installation construction management system and method, and relates to the technical field of municipal pipe network construction management.The application realizes real-time monitoring of a manhole construction object, collects facility number, spatial coordinates, pre-construction, in-construction and post-construction images and timestamp information, constructs a unique identifier of the construction object and generates a standardized information body;on this basis, the spatial consistency coefficient of the construction object, the construction process integrity coefficient and the construction result reliability coefficient are calculated respectively, and compared with the corresponding threshold value for evaluation;when the evaluation result is unqualified, the control strategies such as automatic repositioning, supplementary shooting and recording, rework or manual review are triggered, the abnormal data flow is suspended, and the update and recording are completed until the evaluation meets the standard.The method realizes spatial verification, process constraint and result quality control of the manhole anti-falling net construction process, and improves the construction authenticity, data reliability and management efficiency.

This utility model relates to a microscopic observation device for soil particles in shaking table tests, belonging to the technical field of civil engineering experimental equipment. It includes a vibrating base that supports the entire device and provides controlled vibration power; a fully transparent model box is mounted on the vibrating base to hold the soil particle sample to be observed, and the bottom layer of the fully transparent model box has symmetrically arranged wave-absorbing sponge layers on its left and right sides; a miniature camera assembly is mounted on the vibrating base, vibrating synchronously with the fully transparent model box; the miniature camera assembly includes a camera with high-speed continuous shooting capability, and the frame rate of the miniature camera assembly is not less than 300fps; a horizontal electric guide rail is mounted on the vibrating base; and a vertical electric lifting column is mounted on the horizontal electric guide rail. This utility model effectively eliminates the relative displacement problem caused by the asynchronous movement of the camera equipment and the model box in shaking table tests.

The invention discloses an elevator lock hook bearing axial clearance testing tool based on an intelligent sensor, and relates to the technical field of elevator lock hook bearing axial clearance testing tools based on the intelligent sensor, and the elevator lock hook bearing axial clearance testing tool based on the intelligent sensor comprises a base and a carrier, the base and the carrier are placed on the same horizontal plane, a lifting supporting rod is fixed to the upper surface of the base, and an intelligent control device body is fixed to the end, away from the base, of the lifting supporting rod. According to the elevator latch hook bearing axial clearance test tool based on the intelligent sensor, when a latch hook plate is tested, the connection support, the air cylinder and the piston rod are matched to replace manual operation of a worker to press the latch hook plate, so that the pressure and the position of the latch hook plate are more stable; the problem that the error of data measured during testing is large due to the fact that the applied force is difficult to fix or detect during multiple tests is avoided, and the problem that the instability of manual force application is large is solved.

The invention provides an industrial fiber cloth tensile detection device and a detection method, and relates to the technical field of tensile detection. The detection table is of a long-strip-shaped structure, the digital display end is fixedly installed at one end of the detection table, and the traction motor is fixedly installed at the other end of the detection table. A rail groove is upwards formed in the detection table along the long edge, and a traction detection end is slidably mounted on one side, far away from the digital display end, in the rail groove; one end, close to the digital display end, of the detection table is fixedly provided with a traction seat, one side, close to the digital display end, of the traction detection end is also provided with a movable traction seat, the lower end of the movable traction seat is clamped with the upper end of the detection table in a sliding manner, and to-be-detected cloth is arranged between the two traction seats. The device realizes rapidness, automation and high reliability of cloth clamping. The upper feeding roller and the lower feeding roller in the cloth feeding assembly are matched with the guide supporting tongue, the cloth can be stably and smoothly guided to enter a preset position, the edge of the cloth is effectively prevented from being curled or deviated, and a good foundation is laid for follow-up uniform stress.
