Abstract

The utility model discloses a detachable lifting beam and relates to the technical field of manufacture of lifting mechanical equipment. The detachable lifting beam comprises a cross beam, wherein a plurality of lifting lugs are arranged on the cross beam; the cross beam comprises a main beam and a secondary beam; the secondary beam is connected to two ends of the main beam; a locking device is arranged at the junction between the main beam and the secondary beam; the main beam comprises pin shaft buckle plates and location seam allowances; the pin shaft buckle plates are arranged at the upper parts of two ends of the main beam; the location seam allowances are formed at the lower parts of two ends of the main beam; the secondary beam comprises baffles and a location plate; the baffles are arranged on two sides of one end of the secondary beam; the location plate extends out of the lower part of the secondary beam; pin shafts are arranged on the two baffles in a penetrating manner; the two baffles prop against two sides of the end of the main beam, respectively; the pin shafts are clamped in the pin shaft buckle plates; the location plate is overlapped on the location seam allowances. Compared with the prior art, the detachable lifting beam has the advantages that the cross beam is provided with the main beam and the secondary beam connected to two ends of the main beam; when large-span goods are lifted, the main beam and the secondary beam are combined for use; when small-span goods are lifted, only the main beam is used, thereby reducing a lifting space for lifting the small-span goods and reducing the lifting weight.

Description

Detachable hanging beam

Technical field

The utility model relates to elevator machinery equipment manufacturing technology field, especially a kind of hanging beam for lift cargo.

Background technology

Hanging beam is the special crossbeam for lift cargo, can meet the goods handling of various different spans; Conventionally on hanging beam, be installed with the hanger of multiple suspension Current Collector Sleaves, in lifting job process, can, according to the span needs of lift cargo, select suitable hanger to carry out lifting cargo; Can lift by crane the goods of 327 tons if any a kind of hanging beam, its maximum lifting span is 17 meters, and minimum lifting span is 4.5 meters; In the time of the goods of 4.5 meters of spans of lifting, it is idle that hanging beam exceeds the hoisting function of lifting span part, and the deadweight of this part has increased hoisting weight, takes up room large, has wasted a liter weight and the space that hoists.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of detachable hanging beam that can change according to lifting span hanging beam span.

In order to address the above problem, the technical solution adopted in the utility model is: this detachable hanging beam, comprise the crossbeam that is provided with multiple hangers, described crossbeam has girder and is connected to the auxiliary girder at described girder two ends, and the connecting portion of described girder and described auxiliary girder is provided with blocking device.

In above-mentioned detachable hanging beam technical scheme, technical scheme can also be more specifically: described girder has and is located at the bearing pin buckle on its top, two ends and the positioning spigot of its underpart; Described auxiliary girder have be located at both sides, top, one end plate washer and stretch out the locating plate of its underpart, on two described plate washers, be coated with bearing pin; Two described plate washers connect with the both sides of described end of main beam respectively, and described bearing pin is installed in described bearing pin buckle, and described locating plate is overlapped on described positioning spigot.

Further, described blocking device comprises the securing rod that installed described girder and described locating plate, and described securing rod is provided with draw ring stretching out described girder end face place, is provided with the positioning plate of described draw ring at the end face of described girder.

Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:

1, detachable hanging beam comprises the crossbeam that is provided with multiple hangers, and crossbeam has girder and is connected to the auxiliary girder at girder two ends, and the connecting portion of girder and auxiliary girder is provided with blocking device; In the time of the goods of the large span of lifting, by the use that combines of girder and auxiliary girder; While lifting by crane the goods of little span, only use girder, reduce to lift by crane the goods lifting used space of little span, alleviate the weight of lifting.

2, simple in structure, mounting or dismounting are convenient, use flexibly, can use girder to lift by crane the goods of little span in little place, lifting space, meet the goods handling needs of various spans.
