Abstract

The utility model discloses a lifting sling for acceptance inspection of a large-scale traveling crane. Through holes are arranged at the centers of four lifting hook plates, the four lifting hook plates are arranged on the top surface of a beam at intervals in two-two corresponding mode and are symmetrical with the center of the beam as a center, two pin shafts respectively penetrate in the through holes of the corresponding lifting hook plates, one ends of a plurality of columns are vertically arranged on a bottom surface frame at intervals along a central axis of the bottom surface frame, the other ends of the plurality of columns are vertically arranged on the bottom surface of the beam at intervals, two ends of a plurality of diagonal draw bars are respectively connected with two side faces of the beam and two side edges of the bottom surface frame, and the diagonal draw bars correspond to the plurality of columns in position. The lifting sling facilitates achievement of load tests of the large-scale traveling crane, effectively improves efficiency of the traveling crane load tests, guarantees accuracy of the traveling crane load tests, and avoids potential safety hazard.

Description

Suspender is used in the lifting that is used for large-scale driving examination

Technical field

The utility model relates to a kind of lifting that is used for large-scale driving examination and uses suspender.

Background technology

Large lifting equipment all need pass through loaded test like driving etc. after overhaul, with the load condition of check driving; The driving loaded test adopts directly lifting counterweight or other similar whole counterweights usually.But the actual conditions production scene does not generally possess the lifting counterweight that is used for loaded test; Can only the similar whole counterweight of field fabrication, and the whole counterweight of field fabrication needs suitable material and reach the load of TR, and waste time and energy; Reduced the efficient of driving acceptance test; Interim simultaneously whole counterweight of making not necessarily satisfies the load requirement of acceptance test, has influenced the accuracy of driving acceptance test, also has certain potential safety hazard.

Summary of the invention

The utility model technical matters to be solved provides a kind of lifting that is used for large-scale driving examination and uses suspender; Utilize the convenient loaded test that realizes large-scale driving of this suspender; Effectively improved the efficient of driving loaded test, the accuracy of the loaded test of guaranteeing to drive a vehicle has been avoided potential safety hazard.

For solving the problems of the technologies described above; The lifting that the utility model is used for large-scale driving examination comprises four blocks of suspension hook plates, two bearing pins, crossbeam, bottom frame, some columns and some digonal links with suspender; Said four suspension hook plate centers have through hole and said crossbeam end face is located at corresponding in twos interval; Said four blocks of suspension hook plates are symmetrical in said crossbeam center; Said two bearing pins penetrate respectively in the through hole of said cooresponding two blocks of suspension hook plates; Said some columns one end is located on the said bottom frame along said bottom frame central axis perpendicular separation, and said some column other end perpendicular separations are located at said crossbeam bottom surface, and said some digonal links two ends connect the dual-side of two sides and bottom frame of said crossbeam and corresponding with said some stud respectively.

Further, above-mentioned crossbeam can adopt box girder or H section steel beam.

Because being used for the lifting of large-scale driving examination, the utility model adopted technique scheme with suspender; Promptly four suspension hook plate centers have through hole and the corresponding in twos crossbeam end face of being located at interval; Four blocks of suspension hook plates are symmetrical in the crossbeam center; Two bearing pins penetrate respectively in the through hole of cooresponding two blocks of suspension hook plates; Some column one ends are located on the bottom frame along bottom frame central axis perpendicular separation, and some column other end perpendicular separations are located at the crossbeam bottom surface, and some digonal links two ends connect the dual-side of two sides and bottom frame of crossbeam and corresponding with some stud respectively.The convenient loaded test that realizes large-scale driving of this suspender has effectively improved the efficient of driving loaded test, and the accuracy of the loaded test of guaranteeing to drive a vehicle has been avoided potential safety hazard.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is done further to specify:

Fig. 1 is used for the structural representation of the lifting of large-scale driving examination with suspender for the utility model,

Fig. 2 is the lateral plan of Fig. 1,

Fig. 3 is the birds-eye view of Fig. 1.

The specific embodiment

Like Fig. 1, Fig. 2 and shown in Figure 3; The utility model is used for lifting that large-scale driving checks and accepts and comprises four blocks of suspension hook plates 1, two bearing pins 2, crossbeam 3, bottom frame 6, some columns 4 and some digonal links 5 with suspender; Said four suspension hook plate 1 centers have through hole and said crossbeam 3 end faces are located at corresponding in twos interval; Said four blocks of suspension hook plates 1 are symmetrical in said crossbeam 3 centers; Said two bearing pins 2 penetrate respectively in the through hole of said cooresponding two blocks of suspension hook plates 1; Said some columns 4 one ends are located on the said bottom frame 6 along said bottom frame 6 central axis perpendicular separations, and said some column 4 other end perpendicular separations are located at said crossbeam 3 bottom surfaces, and said some digonal links 5 two ends connect the dual-side of two sides and bottom frame 6 of said crossbeam 3 and corresponding with said some columns 4 positions respectively.

Further, for improving the structural rigidity of this suspender, guarantee reliability, above-mentioned crossbeam 3 can adopt box girder or H section steel beam.

After large-scale driving overhaul; Can conveniently implement loaded test through this suspender; Four blocks of suspension hook plates and two bearing pins of this device constitute two suspension centres of driving a vehicle; Crossbeam, bottom frame, some columns and some digonal links constitute hanging basket and guarantee the rigidity and the reliability of structure, and each parts of this suspender can be through being welded to form; During the driving loaded test, travelling crane hook or hoist cable penetrate two bearing pins, load the counterweight that slab or bar base are formed in the hanging basket, but the counterweight flexible configuration can be implemented loaded test through this suspender of driving lifting, has guaranteed the safety of loaded test again.

This hanger structure is simple, and is easy to make, can adapt to the loaded test of different large-scale drivings, avoided lacking the inconvenience of loaded test counterweight, improved the efficient of loaded test.
