Background

The lifting lug is a stressed member which is arranged on equipment and used for lifting, and common lifting lug forms comprise a plate type lifting lug and a tubular type lifting lug. The plate type lifting lug is a lifting lug made of a perforated plate type steel plate at a stressed tie point during hoisting, and the tubular type lifting lug is a lifting lug made of a steel pipe or other metal pipe fittings at a stressed tie point during hoisting.

In the process of hoisting equipment, two cranes generally hoist simultaneously, one crane hoists the upper end of the equipment, the other crane hoists the lower end of the equipment to prevent the lower end of the equipment from being damaged due to friction with the ground, and a lifting lug connected with the equipment by the crane at the lower end of the hoisting equipment is called a tail slipping lifting lug.

The combination of the existing plate-type lifting lug and the shackle is only suitable for the lifting of the tail sliding lifting lug which is lower than the ground, and is convenient for picking and hanging the tail sliding rigging system. Especially when the tail slipping force is more than 150 tons, a large shackle is required to be connected with the plate-type lifting lug, the shackle is difficult to unhook due to heavy weight, and the safety risk is high. The welding of double-barrelled swift current tail lug is usually welded on equipment both sides, need use the compensating beam to place wire rope and catch up with the car to swift current tail in-process compensating beam easily bumps with equipment platform or equipment barrel.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the tail hanging point is higher than the ground to cause inconvenient tail rigging removal, and provides a single-point tubular tail-sliding lifting lug, and the tail-sliding rigging removing and hanging system is easier than the matching of a communicating plate-type lifting lug and a shackle in the hoisting process; the tail dragging rope device can save a large amount of work, can reduce the safety risk of a tail dragging rope device picking and hanging system, and is particularly suitable for tail dragging of equipment with tail dragging force of more than 150 tons.

In order to solve the technical problem, the utility model discloses a following technical scheme realizes:

the utility model provides a single-point tube type swift current tail lug, includes that the bottom welds in the mainboard of being hung the equipment, mainboard bottom both sides are connected with and weld in the backing plate of being hung the equipment, the mainboard middle part is seted up the through-hole and is worn to be equipped with the hollow shaft in this through-hole, the hollow shaft with the mainboard welding just the axis of hollow shaft is perpendicular to the mainboard, the hollow shaft both ends are fixedly connected with the baffle respectively.

Furthermore, a cross rib plate or a cross rib plate is arranged inside the pipe shaft.

Furthermore, the main plate is one, and the pipe shaft is bilaterally symmetrical with the main plate as a central plane.

Furthermore, the main plates comprise two parallel main plates, and the pipe shafts are bilaterally symmetrical by taking the symmetrical planes of the two main plates as central planes.

The utility model has the advantages that:

the single-point tubular type tailing lug of the utility model has the advantages of simple structure, convenient manufacture and lower cost, and can directly utilize the design and materials of the existing plate type lug and tubular type lug; the hoisting operation is convenient, the small truck cranes at other sites and stations are not required to be matched with each other for unhooking, and the requirement on the sites is low.

Compared with a plate-type lifting lug and a shackle combination, the single-point tube-type tail sliding lifting lug of the utility model has the advantages that the hook can be conveniently unhooked, a worker can directly control the rope sliding to unhook on the ground, and when the tail sliding lifting point is higher than the ground, a scaffold table does not need to be erected or a hanging basket does not need to be used for high-altitude hook unhooking, so that the safety is high;

(III) the utility model discloses a single-point tubular swift current tail lug compares with double-barrelled swift current tail lug, need not adopt the compensating beam again, and the swift current tail in-process is difficult for bumping mutually with equipment platform or equipment barrel.
