Single hanger plate structure is processed into the interior setting lockplate fixed by screw, round steel lower part, and internal clear span is slightly larger than between double platform slings
Single platform sling thickness most descends section pull rod to connect by bolt with aperture port strobe or trash rack lifting lug, uses between connected pull rod
It is bolted.By the above method, small-sized pull rod is machined into using a round steel, is simple to manufacture, without welding, and intensity
And stability is preferable, and the safety of pull rod operation is effectively ensured；It is connected by screw bolts between connected pull rod, section pull rod is most descended to pass through
Bolt is connect with aperture port strobe or trash rack lifting lug, replaces pin shaft to connect with bolt, saves processing and manufacturing pin shaft and scene peace
The program for filling pin shaft, effectively increases manufacture and the installation effectiveness of pull rod.
Based on above method, a kind of improvement structure of small-sized pull rod of the invention, including small-sized pull rod, the small-sized pull rod are used
It is locked in the locking beam that aperture port strobe or trash rack are connected to inspection platform；The small-sized pull rod is using a round steel and passes through
It is machined into；The round steel top is equipped with double hanger plate structures；Double hanger plate structure lower parts are equipped with part and scabble into symmetrical concave
Plane；Round steel lower part is equipped with single hanger plate structure.
Further, the setting lockplate fixed by screw in the concave plane；Concave plane and lockplate are with brill
Threaded hole.
Further, internal clear span is slightly larger than single platform sling thickness between double platform slings.
Further, the small-sized pull rod lower part is connect by bolt with aperture port strobe or trash rack lifting lug.
Further, it is connected by screw bolts between connected small-sized pull rod.
Compared with prior art, the invention has the following beneficial effects:
(1) small-sized pull rod is machined into using a round steel, is simple to manufacture, without welding, and intensity and stability compared with
It is good, the safety of pull rod operation is effectively ensured；It is connected by screw bolts between connected pull rod, section pull rod is most descended to pass through bolt and aperture
Port strobe or the connection of trash rack lifting lug, replace pin shaft to connect, save the journey of processing and manufacturing pin shaft and in-site installation pin shaft with bolt
Sequence effectively increases manufacture and the installation effectiveness of pull rod.
(2) internal clear span is slightly larger than single platform sling thickness between double platform slings, is embedded on lower section pull rod convenient for upper section pull rod lower part
Portion.

Specific embodiment
The present invention is described in detail below with reference to attached drawing, is not described in detail in the present invention, is this field
Conventional technical means known to technical staff.
Please refer to Fig. 1-10: firstly, the present invention is for the aperture port strobe and trash rack in hydraulic structure, microstome
Trash rack 1 is locked by the locking beam 4 that small-sized pull rod 2 is connected to inspection platform 3.It can be seen that from Fig. 1 and Fig. 2 of the invention
Small-sized pull rod 2 is that multistage is sequentially connected to be formed up and down, is connected between connected small-sized pull rod 2 using bolt 12.Under small-sized pull rod 2
Portion is connect by bolt 12 with microstome trash rack lifting lug 13；Small-sized 2 top of pull rod is the maintenance being fixed on hydraulic structure
Platform 3, inspection platform 3 are equipped with locking beam 4.
From Fig. 3-10 as can be seen that the structure of each section of small-sized pull rod 2 is all made of a round steel 5 and is machined into, this hair
Bright pull rod is integrally formed by multistage round steel 5, and 5 top of round steel processes 6 structure of platform sling in pairs, and the structure of double platform slings 6 is shown in Fig. 8, can
To find out that double platform slings 6 are made of straight panel of two pieces of erected parallels at the top of round steel 5, a U-type groove is formed.It is corresponding on two boards
Cross through hole is arranged in position, and the through-hole overlapping on two boards, through-hole is as lifting hole(eyelet) or bolt hole.Double 6 structure bottom of platform sling parts
Scabble into symmetrical concave plane 7；The setting lockplate 9 fixed by screw 8 in concave plane 7；Concave plane 7 and lockplate
9 match auger shell pit 10.
Single 11 structure of platform sling is processed into 5 lower part of round steel, and the structure of single platform sling 11 is one piece and the straight of 6 bottom of round steel is arranged in
Plate uses bolt 12 successively after the U-type groove between the two boards of double platform slings 6 for being embedded in the top of another round steel 5 below
Across locking, therefore, it is equipped with the through-hole with the through-hole corresponding position on double platform slings 6, on single platform sling 11 to be passed through bolt 12.
It in addition, internal clear span is slightly larger than 11 thickness of single platform sling between double platform slings 6, but should not be too large, double platform slings 6 be embedded in single platform sling 11
Can also slightly have subject to activity space after U-type groove, can choose internal clear span between double platform slings 6 and be greater than 11 thickness 0.5- of single platform sling
20mm。
It is above specific application example of the invention, there are other embodiments of the invention, all to use equivalent replacement
Or the technical solution that equivalent transformation is formed, it all falls within protection scope of the presently claimed invention.
