A rod holder configured to operate in a two-stage loading manner allows a rod to be easily received. A minimally invasive system for spinal surgical operation allows a rod to be more accurately and stably received to a pedicle screw inserted into a vertebra by using the rod holder, a rod guide and a rod guide holder. The rod holder may control a rod with three stages: a first loading stage for moving back and fixing a loading unit to fixedly grip the rod; a second loading stage for rotatably gripping the rod; and a rod mounting stage for separating the rod from the rod holder. The spine surgery system includes a pair of rod guides connected to upper ends of a pair of pedicle screws to form a moving path of the rod; a rod holder; and a rod guide holder for defining an insertion path.

The invention relates to telegraph pole mounting equipment, in particular to telegraph pole displacement and upright equipment for city buildings. According to the telegraph pole displacement and upright equipment for the city buildings, manual transportation by workers is not required, the time and labor are saved, and during mounting, the mounting position of a telegraph pole is precise and stable. The telegraph pole displacement and upright equipment for the city buildings comprises a mounting frame, first supporting seats, a wheel axle, tires, a first sliding rail, a first sliding block and the like; and the first supporting seats are mounted on the left and right sides as well as the front and rear sides of the lower side of the mounting frame in a welded mode. According to the telegraph pole displacement and upright equipment for the city buildings, the effects that manual transportation by the workers is not required, the time and labor are saved, and during mounting, the mounting position of the telegraph pole is precise and stable are achieved; and the telegraph pole can be mounted precisely and stably in a mode that a second air cylinder drives the telegraph pole to movedownwards to enter the mounting position.

The invention relates to the technical field of gas pipeline partitions, in particular to an automatic installation mechanism for large-scale gas pipeline partitions, comprising pipelines, first hydraulic components are arranged at the upper and lower ends of the pipelines, and a first hydraulic component is installed directly above the pipelines an outer frame, a moving frame is installed on the inner side of the outer frame, a first cross bar is arranged at the upper end of the moving frame, a second cross bar is arranged at the lower end of the moving frame, and a second sliding bar is arranged on the outer frame A groove and a third chute, a second hydraulic assembly is installed on the top end of the moving frame, the upper end of the second hydraulic assembly is a left frame, and the lower end of the second hydraulic assembly is a right frame. The invention can automatically complete the separation of the pipeline through the remote end of the hydraulic system, send the partition plate and the sealing ring into the separation area of ​​the pipeline flange, and automatically clean the slag on the flange contact surface. The operation is fast, the functions are various, and the use is convenient. Strong usability, safe and reliable.

The invention relates to telegraph pole equipment, in particular to transporting and burying equipment for telegraph poles. According to the transporting and burying equipment, the telegraph poles canreach the mounting positions where the telegraph poles need to be mounted without needing secondary transporting, and during mounting, the telegraph poles can be accurately mounted to the mounting points where the telegraph poles need to be mounted. The transporting and burying equipment comprises a bottom plate, brackets, wheel axles, tires, a fixing plate, a placing plate, a supporting plate and the like; and the brackets are mounted on the left side and the right side as well as the front side and the rear side of the lower side of the bottom plate in a welded mode, and the wheel axles areconnected to the lower sides of the brackets in a rotating mode. The transporting and burying equipment for the telegraph poles achieves the effects that the telegraph poles can reach the mounting positions where the telegraph poles need to be mounted without needing secondary transporting, and during mounting, the telegraph poles can be accurately mounted to the mounting points where the telegraph poles need to be mounted, and the falling speed of the telegraph poles can be controlled manually by adopting a rotating disc so that the telegraph poles can be accurately and stably mounted.

The invention relates to a modularized transverse moving device. The modularized transverse moving device comprises two frame bodies symmetrically connected to the front end of a machine frame; sliding blocks are arranged in the two frame bodies; slideways are arranged on the upper end surfaces and the lower end surfaces of the sliding blocks, and the slideways on the upper end surfaces and the lower end surfaces of the slide blocks make contact with the upper end surfaces and the lower end surfaces of the frame bodies respectively; through holes I are formed in the middle of the sliding blocks and are parallel to the slideways; screw boxes are arranged on the two frame bodies respectively; screws on the screw boxes penetrate through the through holes I; nuts are arranged on the outer sides of the screws in a sleeving mode and are fixed in the through holes I; sliding grooves are further formed in the sliding blocks and are perpendicular to the slideways; the through holes I penetrate through the sliding grooves; locking pins are arranged in the sliding grooves; locking oil cylinders are connected outside the sliding grooves; one ends of the locking pins are connected to piston rods of the locking oil cylinders; through holes II are formed in the locking pins, and the through holes I communicate with the through holes II all the time; positioning blocks are further arranged on the sides, opposite to the locking oil cylinders, of the sliding blocks; two speed reducers are arranged at the outer ends of the two screws respectively and are connected through a coupler; and a hydraulic motor is connected to one of the speed reducers.
