This utility model discloses a detection head fixing assembly for an automatic inspection machine, belonging to the technical field of automatic inspection machines. It includes a mounting plate, a connecting plate mounted on the front of the mounting plate, and a detection head body fixedly connected to the front of the connecting plate, along with a locking device assembled within the connecting plate. In this utility model, a return spring provides a return force during the movement of the sliding rod, assisting the limiting plate in quickly returning to its original position upon release, thus improving operational efficiency. Furthermore, a circular plate is sleeved on the sliding rod via a bearing, forming a sliding fit with the sleeve, ensuring smooth movement of the sliding rod during pushing and rotating, and preventing jamming. In summary, this utility model, through the coordinated cooperation of the sliding rod, the limiting plate, the transverse groove, and the limiting slot, achieves rapid insertion, rotational positioning, and stable locking of the detection head body, possessing technical advantages of quick installation, reliable structure, and simple operation, significantly improving the efficiency and assembly safety of the inspection equipment.

This invention provides a quick-release bird spike device for power lines, relating to the technical field of bird-proof devices for high-voltage transmission lines. It includes a clamping base, a bird spike connecting seat mounted in a lifting manner within a storage sleeve, and bird spikes mounted on the upper part of the connecting seat. Telescopic support rods are connected to both sides of the connecting seat via pivots. The telescopic support rods on the sides away from the connecting seat are pivotally connected to a semi-circular drive sleeve. An abutment limiting claw is integrally formed on the outer side of the connecting seat. In the retracted state, the bird spikes are clustered together and unfolded after installation, effectively preventing injury to people from their sharp ends. The elastic force generated by the compression spring causes the abutment limiting claw to be fixedly installed on the crossarm. The installation process utilizes the leverage effect of the semi-circular drive sleeve, making installation and disassembly relatively simple while ensuring reliable stability after installation, reducing the risk of falling, and facilitating subsequent repositioning.

The utility model relates to abrasive wheel technical field, especially safety type heavy load abrasive wheel, the utility model adopts the technical scheme: including the cylindrical abrasive wheel main part structure of central shaft is left and right direction, the outer cylindrical surface of abrasive wheel main part structure is equipped with the main body heat -resisting safety groove of uniform distribution, the left and right two end surface of abrasive wheel main part structure is equipped with the symmetrical conical center cooperation safety groove, the inboard position of center cooperation safety groove is equipped with conical stable combination safety groove, the size of inboard position of stable combination safety groove is greater than the size of the center cooperation safety groove connection position, the center position of stable combination safety groove is equipped with the integrated reinforcing center cooperation column, the utility model has the advantages of: can cooperate with reinforcing installation accessories and carry out the fastening cooperation of inlay type, and the cooperation position deforms outward after fastening, can form reliable anti -looseness cooperation effect, guarantees the overall bearing capacity of abrasive wheel when using is stronger, and the shock resistance is better.

This invention discloses a construction method for a pipeline installation lifting gantry device suitable for confined spaces. The pipeline installation is completed through steps including modular gantry assembly, pipeline traction or coordinated transport, synchronous lifting and lateral positioning, segmented acceptance, and hydrostatic testing. Laterally movable pulley assemblies are installed on the upper and lower parts of the gantry, working in conjunction with a self-locking lifting mechanism to achieve synchronous lateral movement and alignment of the pipeline while it is being lifted, allowing the pipeline to quickly align with the bracket and be secured. This method reduces reliance on large hoisting equipment in confined environments such as culverts and pipe galleries, minimizing manual handling and repeated lifting and lowering, and improving installation efficiency and alignment accuracy. Simultaneously, measures such as travel limiters, segmented inspection stops, diagonal bracing for stability, and base leveling enhance operational safety and overall stability, and reduce the risk of collision and wear on the pipeline's external anti-corrosion layer.

This invention provides a spring compression testing device, belonging to the technical field of spring testing equipment. The device includes a compression fixture body, a guide and limiting assembly, and at least one radial limiting member. The compression fixture body is mounted on the lower clamp of the testing equipment and has an axial compression space inside. The top of the compression space has a limiting structure for compressing the spring. One end of the limiting assembly is fixedly connected to the upper clamp of the testing equipment, and the other end extends through the limiting structure into the compression space to limit the deformation of the spring under test radially. The radial limiting member is detachably mounted on the compression fixture body and extends into or through the compression space. The portion extending into the compression space is arranged on one side of the guide and limiting assembly to limit the swaying of the spring under test placed on the guide and limiting assembly radially. This invention primarily addresses the technical problems in the prior art where clamping is difficult, stability is poor, and spring bending is easily caused during compression testing of small-diameter, long springs.
