Abstract
The invention relates to a horizontal cross bar pneumatic lifting appliance for hoisting concrete pipes, comprising a lifting beam and lifting hook assemblies connected at two ends of the lifting beam, and the lifting hook assemblies are driven by a driving device to do left-and-right movement in horizontal direction. The horizontal cross bar pneumatic lifting appliance has the advantages that (1) the operation is simple, an air source is only needed to be controlled on the ground, and the overhead lifting appliance can be controlled; (2) the lifting beam has high strength to ensure the lifting safety; (3) the upper end surface of the transverse part of each lifting hook assembly is contacted with the inner wall of the concrete pipe, and an elastic plate is provided, so that the inner wall of the concrete pipe can be prevented from being damaged; (4) an elastic plate is also arranged on the inner end surfaces of the lifting hook assemblies, so that the end surface of the concrete pipe can not be impacted; and (5) the lifting hook assemblies and the lifting beam slide relative to each other simply and reliably.
Description
Technical field
The present invention relates to a kind of pneumatic suspender of horizontal cross bar that is used for handling concrete pipe, belong to pipeline hoisting technology field.
Background technology
Prestressed concrete cylinder pipe (being called for short PCCP) is the novel pipeline material that grows up domestic nearly more than ten years.This pipeline material is a kind of compound type tubing that high strength, height are done oozing property and high leakproofness that possesses, and it has been gathered raw and auxiliary material manufacturings such as sheet steel, medium plate, deformed steel, regular reinforcement, high-strength prestressed steel wire, high strength concrete, high-strength mortar and rubber seal and has formed.This pipeline material not only combines the advantage of common prestressed concrete pipe and steel pipe, and is particularly useful for heavy caliber, senior engineer's pressure and high earthing and engineering-environment.Prestressed concrete pipe (be called for short PCCP) is meant in the cement concrete tube core outer felt that has steel cylinder around the ring orientation prestress steel wire and make cement mortar protective course and the pipe processed.Because the length of PCCP pipe is 5m or 6m in the GB, the PCCP pipe is produced and is accomplished, and generally adopts horizontal stacking, when transporting, to the handling of the PCCP pipe of horizontal stacking, just needs a kind of special hanger of safe, easy, low energy consumption.
Summary of the invention
The present invention is directed to above-mentioned defective, purpose is to provide a kind of convenient, simple in structure pneumatic suspender of horizontal cross bar of lifting that has.
The technical scheme of the present invention's employing is for this reason: the present invention includes slinging beam and the hook assembly that is connected the slinging beam two ends, said hook assembly is driven by actuating device and makes its sway in the horizontal.
Said actuating device is a pneumatics, comprising: trachea road and connected tracheae, tracheae are communicated to a cylinder assembly and drive the hook assembly side-to-side movement through cylinder rod.
Said hook assembly is L type structure, and the hook assembly transverse part is in the vertical portion to setting.
Its upper surface of said hook assembly transverse part, inner end surface are established elastic plate.
Said slinging beam is if the slide rail of hook assembly side-to-side movement.
Advantage of the present invention is: 1) easy and simple to handle, only need can handle and be hung in aerial suspender at the Ground Control source of the gas; 2) slinging beam intensity is big, guarantees to lift by crane safety; 3) hook assembly transverse part upper surface contacts with the concrete inside pipe wall, is furnished with elastic plate, and the concrete inside pipe wall prevents to damage; 4) the hook assembly inner end surface also is provided with elastic plate, the concrete pipe end face of can not damaging; 5) slide relative of hook assembly and slinging beam is simple, reliable.
Description of drawings
Fig. 1 is a structural representation of the present invention.
1 is that hook assembly, 2 is that slinging beam, 3 is that trachea road, 4 is that cylinder assembly, 5 is elastic plate among the figure.
The specific embodiment
Suspender is made up of slinging beam 2, hook assembly 1, cylinder assembly 4 etc.; Before the handling concrete pipe, external source of the gas is connected on 3 places, trachea road that are fixed on the slinging beam 2, thereby handling time control gas source and flow amount size control cylinder bar is flexible; The top of cylinder rod connects with the upper surface of hook assembly 1, and tail cylinder is fixed on the slinging beam 2 through cylinder block, when cylinder rod is flexible, drives hook assembly 1 and in the slide rail of slinging beam 2, slides, thereby accomplish the action that hook assembly 1 stretches; Stretch out when controlling source of the gas manipulating cylinder bar, hook assembly 1 moves, and stretches out from slinging beam 2 two ends, and makes whole suspender move down into the concrete pipe top of needs lifting through jacking system; Manipulating cylinder bar withdrawal then, hook assembly 1 inwardly moves to and is hung the concrete pipe orifice, and after treating that hook assembly 1 transverse part is whole and moving in the concrete pipe, again with whole suspender lifting, thereby the concrete pipe built on stilts of slinging is to the place that needs handling.
The present invention establishes elastic plate 5 at upper surface, the inner end surface of hook assembly 1 transverse part, and is injury-free with protection concrete inside pipe wall, end face.
Claims (5)
