The utility model discloses cast steel trestle hinged support based on arc -shaped groove -half axle cooperation relates to the technical field of fabricated steel structure trestle, including upper support and lower support, the upper support is opposite distribution with lower support, the upper support includes upper roof, and the bottom fixedly connected with upper support of upper roof has, and the bottom of upper support is provided with arc groove, and arc groove is along the width direction distribution of upper roof, the lower support includes lower bottom plate, and the top fixedly connected with lower axle support of lower bottom plate, and the upper half of lower axle support is semicircle, and with arc groove is pasted together, one end fixedly connected with the fixed sealing plate of arc groove, and the fixed flange is fixedly connected on the fixed sealing plate, and the side sealing plate is arranged to the side of fixed sealing plate of lower axle support back to the fixed sealing plate. This cast steel trestle hinged support based on arc -shaped groove -half axle cooperation utilizes the precision cooperation of upper support, arc groove and lower axle support, realizes smooth rotation around the shaft and strictly restricts longitudinal and transverse translation displacement when reliable bearing, ensures the stability of structure.

This invention provides a screening device for road and bridge construction materials, including a frame, a vibrating component, and a screening assembly. The vibrating component is connected to the frame. The screening assembly includes a base shaft, a first screen, a second screen, a first elastic element, a first telescopic rod, a second elastic element, and a second telescopic rod. The base shaft is rotatably connected to the frame. The first and second screens are respectively connected to the left and right sides of the base shaft. The first elastic element is connected to the first screen, with one end connected to the base shaft. Both ends of the first telescopic rod are rotatably connected to the frame and the first elastic element, respectively. The second elastic element is connected to one end of the second screen along the front-rear direction, with one end connected to the base shaft. Both the first and second elastic elements are wavy. Both ends of the second telescopic rod are rotatably connected to the frame and the second elastic element, respectively. Locking elements are provided on both the first and second telescopic rods. This invention simplifies the screen leveling process and improves screening efficiency through the screening assembly.

The utility model discloses an auxiliary tool for detecting the bolt fastening force of wind power generation equipment, which relates to the technical field of bolt fastening force detection and comprises a handle, the end part of the handle is connected with a wrench head, the outer side of the wrench head is covered with a protective cover, limiting rods are symmetrically inserted in the protective cover, and the longitudinal section of each limiting rod is of a T-shaped structure. A display screen is arranged on the side edge of the handle. By arranging the protective cover and the limiting rod, in the using process, the rotating requirement of the protective cover can be met through mutual matching of the protective cover and the limiting rod, the outer side of the wrench head can be surrounded and protected when the wrench head is not used while normal use of the wrench head is not affected, and therefore the wrench head is prevented from being damaged due to collision with hard objects; and the rubber sleeve and the rotating roller are arranged, and in the using process, the rubber sleeve and the rotating roller are matched with each other, so that external force borne by the end of the protective cover can be reduced, and the protective cover is protected.

This disclosure proposes a containerized cargo transfer platform, including a platform body and a rotating module. The platform body is used to carry and transport cargo. The rotating module is disposed on the platform body and includes at least one set of rotating rollers, at least one set of omnidirectional wheels, and a first drive mechanism. The at least one set of rotating rollers and at least one set of omnidirectional wheels are arranged at intervals. The first drive mechanism is drivenly connected to the rotating rollers. When the containerized cargo transfer platform rotates cargo, the first drive mechanism drives the rotating rollers to rotate, thereby rotating the cargo, while the omnidirectional wheels assist in supporting the cargo. Through the above design, this disclosure utilizes rotating rollers to achieve lifting, carrying, and rotation of cargo, while simultaneously utilizing omnidirectional wheels to assist in supporting the cargo. Due to the omnidirectional rolling characteristics of the omnidirectional wheels, they can also coordinate with the rotation of the cargo. Accordingly, this disclosure has higher rotational accuracy and can achieve the rotation of large-tonnage cargo.
