Since the two ends of the top support rod are respectively provided with radial pressurizing parts, the top support rod is extended along the rod body and is firmly suspended in the narrow space, which is convenient for disassembly and assembly, effectively reduces the labor intensity of on-site construction personnel, and improves the construction efficiency. Efficiency, it can be suitable for narrow spaces of various shapes and structures, and has high practical value.
[0028] In one embodiment, the connectable track assembly includes several track assemblies connected in sequence, and the top strut assembly cooperates with the connectable track assembly so that the combined tooling can be infinitely extended in a narrow space. Each track assembly includes a section of an attachable track 8, one end of the attachable track is sleeved with a track sleeve 9, and the upper surface of the other end is provided with a fixing hasp 11 to fix the track sleeve and the attachable track For connection, a hoisting ring 12 is arranged above the connectable track, the hoisting ring is used to connect with the chain, a pulley assembly is placed in the connectable track, and a sling 13 is suspended below the pulley assembly, and the sling is used for hoisting in a narrow space items that need to be transported.
[0029] Specifically, the length of the track sleeve accounts for 1/4--1/6 of the length of the connectable track, one end of the connectable track is inserted into the track sleeve, and a stop baffle is arranged in the center of the track sleeve, so that the One end of the connectable track can only be inserted into the half position of the track sleeve. At the same time, the outside of the track sleeve is provided with a locking member 10 to be matched with the fixed hasp, so that the two adjacent connectable tracks can pass through the track sleeve. Fixed connection. Further, the track sleeve here is a gradual structure with a slightly larger diameter at both ends and a slightly smaller diameter in the middle, which ensures the firmness of the connectable track after insertion, and will not fall off when it is stressed, ensuring the safety of use. sex. At the same time, the middle of the top support rod is provided with a through hole, the hook 5 passes through the through hole and is fixed with a nut 6, a chain 7 is hung below the hook, and the top support rod and the track assembly are connected by a chain.
[0030] Further, the radial pressure booster includes bolts 2, the two ends of the top support rod are provided with internal threads matching the bolts, the ends of the bolts are provided with a support plate 3, and a rubber gasket 4 is bonded to the outside of the support plate. By turning the bolt, the length of the top support rod can be adjusted, so that the top support rod can be fixedly connected with the two side walls of the narrow passage through outward radial tension. In order to achieve a better radial pressurization effect, the rubber gasket is in the shape of a concave suction cup, and there is a water injection groove on the suction cup surface of the concave suction cup. When in use, water can be injected into the water injection groove now, which can make adsorption The effect is better, to ensure that the top support rod will not fall off during the transportation of objects.
[0031] Alternatively, an air-extraction pressing member is arranged on the support plate, and one end of the air-extracting pressing member is communicated with the inner side wall of the rubber gasket. When the rubber gasket is attached to the side wall of the narrow space, it is It can vacuum between the rubber gasket and the side wall of the narrow space, further expand the radial pressure, not only safe and reliable operation, but also further improve the pressure bearing range of the connectable track assembly, which can be transported in a narrow space Heavy parts.
