The invention discloses an anti-collision protection device for an alarm, and aims at solving the problems that an existing alarm protection device is troublesome to disassemble and assemble and an alarm sound transmission is hindered. According to the technical scheme, the anti-collision protection device is characterized by comprising a bottom plate, a top plate, a plurality of fixed plates, a plurality of movable plates and an alarm, wherein the top plate is positioned right above the bottom plate, two supporting columns are fixedly connected between the top plate and the bottom plate, thealarm is fixedly connected with the top of the bottom plate, a plurality of protective fences are fixedly connected between the fixed plates and the movable plates, a plurality of fixing holes are formed in the top of the bottom plate at equal intervals, a mounting hole is formed in one side of the fixing holes, a limiting column is arranged in the mounting hole, and one end of the limiting columnextends to the outside of the bottom plate. The anti-collision protection device is reasonable in structure, ingenious in design and easy to operate, the problem that an existing alarm protection device is troublesome to disassemble and assemble and the alarm sound transmission exists is solved, and the anti-collision protection device is good in protection effect, easy to assemble and easy to popularize and use.

The invention discloses a load bearing device. The load bearing device comprises a base, a bearing bar and a load bearing cable, wherein the base is fixed on a mounting foundation, the bearing bar is detachably arranged on the base, one end of the load bearing cable is detachably connected with the bearing bar, and the other end of the load bearing cable is connected with a to-be-hung object. By the arrangement, the load bearing device has the advantages that when detecting equipment or experiment equipment is suspended in the water below a cabin through the load bearing cable, the detecting equipment or experiment equipment can be mounted and demounted conveniently; the load bearing device is high in connection reliability, and the problem that the detecting equipment directly connected to the cabin through a hanging rope is troublesome to mount and demount in the field of navigation scientific researches and scientific investigation is solved.

The invention discloses an electric telescopic antiskid chain for a wheel, and belongs to the tire skid resistance technical field. The electric telescopic antiskid chain includes a plurality of groups of positioning assemblies, chain body assemblies and lifting assemblies; the positioning assemblies are arranged around the circumference of the tire and on the outer surface of a tire at intervals, each group of positioning assembly includes a plurality of linear-arrangement positioning piles, each positioning pile is sleevedly provided with a fixing ring, each fixing ring is symmetrically provided with a pair of second connection seats in the circumferential direction of the tire, and the second connection seats are connected with corresponding second connection seats on the adjacent positioning piles by second tensioning chains; the chain body assemblies are in interval arrangement with the positioning assemblies and are in movably installation with the second tensioning chains between the positioning assemblies; the lifting assemblies are arranged on the side wall of the tire and are in one-to-one correspondence with the chain body assemblies. The electric telescopic antiskid chain has the advantages that connection of the positioning assemblies with the tire is steady, loosening or detachment of the chain body assemblies can be effectively prevented, and the antiskid effect is significantly increased; the problem of troublesome dismantling and mounting of a conventional antiskid chain is solved; and the wear degree of the antiskid chain can be reduced.

The invention discloses a disassembling device and method for the intermediate oil seal of a hydraulic steering machine. The disassembling method for the intermediate oil seal of the hydraulic steering machine comprises the following steps: an intermediate oil seal cutting tool assembly is loaded from the upper opening of a cylinder barrel and assembled with a cutting tool positioning block, the cylinder barrel is arranged on a intermediate oil seal disassembling machine frame, a cutting tool fixing member is connected with the upper end of the cutting tool assembly, and the cylinder barrel is vertically fixed on the center portion of the frame through a fixture; with the lifting of a jack, the cylinder barrel is lifted; the bottom cutter edge of the cutting tool of the cutting tool assembly cuts an oil seal rubber ring and an oil seal skeleton of the intermediate oil seal, a hand shank is rotated repeatedly and the jack is lifted, so that the cutting tool is allowed to rotatably cut so as to disassemble the intermediate oil seal. Under the action of the inner cone slope of the cutting tool, the oil seal skeleton rolls up, the diameter of the intermediate oil seal is reduced, thus the intermediate oil seal is easy to take out. According to the disassembling device and method for the intermediate oil seal of the hydraulic steering machine, the intermediate oil seal can be effectively disassembled from a cylinder barrel assembly without damaging the inner wall of the cylinder barrel, so that the old cylinder barrel can be used again after repair, and the production cost of the subsequent remanufacturing of the hydraulic steering gear is reduced.
