When the lifting sling 20 is used, the sling 20 of the crane penetrates through two ends of the support pipe 1 and is limited by the limiting component 2, the sling 20 is directly connected to a cargo main lifting lug from a crane main hook, the sling 20 is supported by a certain angle through the support rod main body 10, the sling is not required to be separated up and down, and the number of sling tools is reduced; the stay bar main body 10 only achieves the function of propping the sling 20 open, huge tension load for connecting an upper sling and a lower sling is not needed to be born, so that the stress of the stay bar main body 10 is greatly reduced, forged parts, machining items or large thick plates are not needed to specially strengthen the strength of the stay bar, the support tube 1 and the limiting component 2 are common tubes and plates, and the stay bar main body 10 is small in overall appearance size, light in weight, easy to obtain materials, simple in manufacturing process, short in manufacturing period, low in cost and good in recycling economy.

In this embodiment, referring to fig. 2 to 3, the limiting component 2 includes a top pipe 21 and two limiting pipes 22, the supporting pipe 1 is fixedly connected to the middle of the top pipe 21, the two limiting pipes are vertically arranged, the two limiting pipes 22 are vertically connected to two ends of the top pipe 21 to form a limiting groove 201 with an outward opening, and the sling 20 of the crane is inserted into the limiting groove 201. In order to avoid the sling 20 of the crane from being separated from the opening of the limiting groove 201, the limiting component 2 further comprises a stop lever 23, and two ends of the stop lever 23 are detachably connected with the two limiting pipes 22 respectively to close the limiting groove 201, so that the sling 20 of the crane is limited in the limiting groove 201. The top tube 21 and the limiting tube 22 are common tubes, and the arc surfaces of the tubes can provide good smooth contact, so that the abrasion of the sling 20 and the friction force of the limiting assembly 2 can be retrieved. In the embodiment, because the top pipe 21 is subjected to a higher local pressure by the sling 20, an internal counter-reinforcement is added in the middle of the top pipe 21 to increase the supporting force and strength of the top pipe 21. Optionally, the internal counter-reinforcement is a grout, which is cured inside the top pipe 21. Or, the inner reverse reinforcement adopts symmetrically arranged reinforcing ring plates 211, and the reinforcing ring plates 211 are fixedly supported between the pipe walls at two sides in the top pipe 21. Or the inner reverse reinforcement part adopts a thickened plate 212, and the thickened plate 212 is fixedly arranged on the outer side surface of the top pipe 21 in the limiting groove 201; by adopting one or more combinations of the above forms, the load capacity of the jacking pipe 21 can be effectively ensured.

In order to set the position of the spreader sling 20 and facilitate storage and transportation of the stay bar main body 10, referring to fig. 1 and 3, the positions of the two ends of the support tube 1, which are located at the inner side of the limiting component 2, are further respectively connected with a positioning steel wire rope 11, one end of the positioning steel wire rope 11 is connected to the support tube 1 through a hanger arranged on the support tube 1, and the other end of the positioning steel wire rope 11 can be hung on a main hook of a crane. The two ends of the supporting tube 1 are also provided with storage racks 12, the storage racks 12 are triangular structures and are formed by combining three common sectional materials, such as rectangular tubes and the like, so that the supporting rods can be positioned and supported on the top surface of heavy goods or can be stored daily before hoisting. Thus, by setting the length of the positioning steel wire rope 11 and connecting the positioning steel wire rope to the main hook of the crane, the position and the angle of the spreader sling can be set, the spreader sling can be lifted and transferred along with the crane, and meanwhile, the storage operation of the main body 10 of the support rod is convenient. The support of the brace body 10 is positioned on the top surface of a heavy piece of cargo by the storage rack 12 to enable the brace body to be placed on the top surface of the heavy piece and transported with the heavy piece.

In this embodiment, two separate stay bar bodies 10 are separately connected to the slings 20 of the crane to hoist heavy goods at a time. Of course, in other embodiments, referring to fig. 4, for the requirement of an actual hoisting scheme and considering the purpose of further improving the rigidity and the load capacity of the stay rod main bodies 10, two stay rod main bodies 10 may be arranged in parallel in a manner that the two stay rod main bodies 10 are used in combination, a plurality of connecting pipes 30 (the specific form and the number are determined according to the actual requirement) are connected between the two stay rod main bodies 10, so that the two stay rods are combined into a rectangular frame for use, and the connecting pipes 30 may be fixedly connected with the two stay rod main bodies 10, for example, welded; or a detachable connection, such as a flanged connection. So, make the utility model discloses a repacking flexibility ratio is higher, can be according to the demand of actual hoist and mount scheme and load, with many vaulting pole main part 10 exclusive uses or combined use, or many vaulting poles make up into the frame form, improve its hoist and mount scheme and load accommodation.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
