Description
Technical field
The present invention relates to a kind of lifting latch structure and its application methods, belong to prefabricated components lifting technical field.
Background technique
Referring to Fig. 1, Prefabricated stacking floor by be layered stack, it is intermediate be stacked in pallet 1 in a manner of flitch layering, use
Dedicated pallet suspender is lifted by crane and is shifted.Pallet 1 includes at least two parallel H profile steels 2, two H profile steels 2
End forms 4 fixed suspension centres, and the end cross-sectional view of H profile steel 2 is as shown in Figure 2.Pallet suspender is as shown in Figure 3 comprising
There is the plate 4 being arranged in below hoist cable 3, the end which is inserted into H profile steel 2 can implement to lift by crane to pallet 1, H profile steel 2
Side be welded with side limit plate 2.1, in the prior art, this single page plate needs are staggered at H profile steel both ends, i.e., two
Plate is located at the two sides of H profile steel web, could lift by crane pallet 1 balance in this way.The disadvantage is that using this single page plate,
Easily there is torsional deformation in pallet 1 (H profile steel), floor cracking phenomena easily occurs in floor transport process.
Summary of the invention
The H profile steel of pallet is easy the generation of distortion unstability in use in order to prevent, and the present invention provides a kind of rise
It hangs and uses latch structure, specific technical solution is as follows.
A kind of lifting latch structure, which is characterized in that including two identical inserted sheets, two inserted sheets are overlapped
And interval setting, an end of two inserted sheets are clamped with a connecting plate, the connecting plate is described slotting with two simultaneously
Piece is fixedly connected；The latch structure further includes having the through-hole for running through two inserted sheets and the connecting plate；Two institutes
It states between inserted sheet in addition to the connecting plate position has gap.
Using above-mentioned technical solution, gap (in addition to connecting plate position) is formed between two inserted sheets, it should
Gap can be inserted into for the middle pectoral plate of the H profile steel of prefabricated components pallet, and the through-hole is for installing hoist cable, and when use inserts
Latch structure symmetrical centre is almost overlapped with the web of H profile steel, thus can to avoid H profile steel in the prior art distortion the problem of,
Improve reliability and service life.
The inserted sheet and the connecting plate are all made of steel plate, and the connecting plate be weldingly fixed on two inserted sheets end it
Between.The mode of welding may insure that two inserted sheets form reliable and stable structure.Or two inserted sheets and the connecting plate
It is integrally formed, for example is integrally formed by modes such as casting, forging, powder metallurgy.
Further, the inserted sheet is gradually reduced far from one end height of the connecting plate.Because of one end far from connecting plate
For the one end for being inserted into H profile steel, the end being gradually reduced is inserted into the end of H profile steel convenient for latch structure.
Further, the lower edge of the one end of the inserted sheet far from the connecting plate is plane.When inserted sheet is inserted into H profile steel
Afterwards, the lower edge of inserted sheet and the lower wing plate of H profile steel are face contact, on the one hand have reason to reduce stress concentration, improve making for inserted sheet
With the service life, another aspect face contact can increase frictional force, prevent inserted sheet from surprisingly falling off during lifting.
Based on the same inventive concept, the invention further relates to the application methods of above-mentioned lifting latch structure, which is characterized in that
The end of the H profile steel of pallet is inserted into lifting with latch structure, and the web of H profile steel is located at the gap between two inserted sheets
In, the lower edge of the one end of inserted sheet far from the connecting plate is abutted with the lower wing plate of H profile steel, and the through-hole of the inserted sheet, which is connected with, to be hung
Rope is simultaneously located on the outside of the end of H profile steel.
The present invention compared with the prior art, can more lift by crane pallet to balance and stability, reduce security risk,
Improve the service life of pallet, latch structure；Reduce floor cracking fraction defective.Meanwhile not using latch structure of the invention
It needs to be transformed existing pallet, can directly carry out applicable, and for the pallet of coming of new, can not have in H
The side weld side limit plate of fashioned iron, reduces the cost of manufacture of pallet.

Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing.
Referring to fig. 4-8, lifting latch structure includes two identical inserted sheets 5, and two inserted sheets 5 are overlapped and interval is set
It sets, an end of two inserted sheets 5 is clamped with a connecting plate 6, and the connecting plate 6 is fixed with two inserted sheets 5 simultaneously to be connected
It connects；Latch structure further includes having the through-hole 7 for running through two inserted sheets 6 and connecting plate 5；In addition to connecting plate 6 between two inserted sheets 5
Position has gap 8.
Inserted sheet 5 and connecting plate 6 are all made of steel plate, and connecting plate 6 is weldingly fixed between the end of two inserted sheets 5.Ability
Field technique personnel are it is understood that two inserted sheets 5 and connecting plate 6 can also be integrally formed, for example pass through casting, forging, powder
The modes such as last metallurgy are integrally formed.
Inserted sheet 5 is gradually reduced far from one end height of connecting plate 6.Because one end far from connecting plate 6 is be inserted into H profile steel one
End, the end being gradually reduced are inserted into the end of H profile steel convenient for latch structure.Here height refers to that latch structure is in and uses shape
The height of state.
The lower edge of the one end of inserted sheet 5 far from connecting plate 6 is plane.When inserted sheet be inserted into H profile steel after, the lower edge of inserted sheet with
The lower wing plate of H profile steel is face contact, on the one hand has reason to reduce stress concentration, improves the service life of inserted sheet, another aspect face
Contact can increase frictional force, prevent inserted sheet from surprisingly falling off during lifting.The top of the one end of inserted sheet 5 far from connecting plate 6
Edge is also possible to plane, and such latch structure uses in the case where can turning upside down.
The application method of above-mentioned lifting latch structure: the end of the H profile steel 2 of pallet, H are inserted into lifting with latch structure
The web of fashioned iron 2 is located in the gap 8 between two inserted sheets 5, the lower edge and H-type of the one end of inserted sheet 5 far from the connecting plate 6
The lower wing plate of steel 2 abuts, and the through-hole 7 of inserted sheet 5 is connected with hoist cable and is located on the outside of the end of H profile steel.Under use state, bolt knot
Structure symmetrical centre is almost overlapped with the web of H profile steel, thus can to avoid H profile steel in the prior art distortion the problem of, promoted
Reliability and service life.Meanwhile not needing to be transformed existing pallet using latch structure of the invention, it can be with
Directly carry out applicable, and for the pallet of coming of new, fixing suspension centre be can simplify, as shown in fig. 6, can not have in H-type
The side weld side limit plate of steel, reduces the cost of manufacture of pallet, improves safety.
The embodiment of the present invention is described with above attached drawing, in the absence of conflict, the reality in the present invention
The feature applied in example and embodiment can be combined with each other.The invention is not limited to above-mentioned specific embodiment, above-mentioned tool
Body embodiment is only schematical, rather than limitation, those skilled in the art under the inspiration of the present invention,
Without breaking away from the scope protected by the purposes and claims of the present invention, many forms can be also made, these belong to this
Within the protection scope of invention.
