Description
Technical field
The present invention relates to a kind of for aperture port strobe or the small-sized pull rod of trash rack, belongs to hydraulic and hydroelectric engineering metal structure
Technical field.
Background technique
Aperture port strobe lesser for hoisting capacity and trash rack pull rod, sectional dimension is smaller, and steel plate is relatively thin, using biography
The steel flanged beam welding structure of system is easy to burn out steel plate because the thermal stress that welding process generates is larger, therefore the welding matter of small-sized pull rod
Amount should not guarantee that there are security risks, so, there is also deficiencies for the prior art, need to be further improved.
Summary of the invention
The purpose of the present invention is to provide a kind of for aperture port strobe or the small-sized pull rod of trash rack, with more by screw rod
The drawbar unit of component head and the tail connection substitutes existing steel flanged beam and is welded pull rod, to improve the drawing of aperture port strobe or trash rack
The safety of bar, thus overcome the deficiencies in the prior art.
To achieve the above object, the present invention adopts the following technical scheme:
It is of the invention a kind of for aperture port strobe or the Tiebar structure of trash rack, including one group of pipe nipple pull rod；On pipe nipple pull rod
End is double shackle structure, and pipe nipple pull rod lower end is single shackle structure, and the opposite two sides of the pipe nipple pull rod below double shackle are equipped with
A pair of symmetrical lockplate；One group of pipe nipple pull rod is connected through bolt assembly head and the tail.
In aforementioned Tiebar structure, the body of rod of the pipe nipple pull rod is the integral piece that whole solid square steel is processed into；It is described
A pair of locking plate is symmetrically welded on the opposite two sides of pipe nipple pull rod using welding manner.
In aforementioned Tiebar structure, the gap width B between two lifting lugs of the double shackle 6 is greater than the thickness of single platform sling 8
b。
By adopting the above-described technical solution, compared with prior art, the present invention the present invention is added using a solid square steel
Work is simple to manufacture at pipe nipple pull rod, and intensity and stability are preferable, can effectively ensure that the safety of pull rod operation；Pipe nipple pull rod it
Between connected using bolt assembly head and the tail, the lowermost pipe nipple pull rod by bolt assembly and aperture port strobe or trash rack at the top of
Lifting lug connection replaces pin shaft to connect, saves the program of processing and manufacturing pin shaft and in-site installation pin shaft, effectively improve with bolt assembly
The manufacture of pull rod and installation effectiveness.Internal clear span B is slightly larger than the thickness b of single lifting lug between double shackle, draws convenient for upper section pipe nipple
The insertion of bar lower part is lower to save pipe nipple pull rod top；Lockplate is symmetrically welded in pipe nipple pull rod two sides, easily manufactured, because pipe nipple pull rod by
Solid square steel is made, and the thermal stress that welding process generates is solid smaller on square steel influence, and welding quality is guaranteed.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of pull rod；
Fig. 2 is the application example schematic diagram of pull rod.
Description of symbols: 1- trash rack, 2- pull rod, 3- inspection platform, 4- locking beam, 5- pipe nipple pull rod, 6- double shackle,
The mono- lifting lug of 7- lockplate, 8-, 9- bolt assembly, 10- lifting lug.
Specific embodiment
The present invention is described in further detail with reference to the accompanying drawings and examples.
It is of the invention a kind of for aperture port strobe or the Tiebar structure of trash rack, as shown in Figure 1, because pull rod is longer,
The primary structure of pull rod is seen for convenience, the structure at pull rod both ends has only been drawn in Fig. 1, middle section is omitted；The pull rod
Including one group of pipe nipple pull rod 5；5 upper end of pipe nipple pull rod is 6 structure of double shackle, and 5 lower end of pipe nipple pull rod is 8 structure of single lifting lug, double
The opposite two sides of the pipe nipple pull rod 5 of 6 lower section of lifting lug are equipped with a pair of symmetrical lockplate 7；As shown in Fig. 2, one group of pipe nipple pull rod 5 passes through
9 head and the tail of bolt assembly connect and compose the pull rod of microstome trash rack.Whole solid square steel of the body of rod of pipe nipple pull rod 5 is processed into
Integral piece；The pair of lockplate 7 is symmetrically welded on the opposite two sides of pipe nipple pull rod 5 using welding manner.Double shackle 6
Two lifting lugs between gap width B be slightly larger than the thickness b of single platform sling 8.
Embodiment
This example is as shown in Figure 2.From Figure 2 it can be seen that this example is by bolt assembly 9 by one for the pull rod 2 of microstome trash rack
Group 5 head and the tail of pipe nipple pull rod are formed by connecting.Each pipe nipple pull rod 5 as shown in Figure 1, be process by one whole solid square steel,
6 structure of double shackle is processed on solid square steel top, and 6 lower part of double shackle is symmetrically welded with a pair of locking plate 7, and solid square steel lower part adds
Work is at single 8 structure of lifting lug, and internal clear span B is slightly larger than 8 thickness b of single lifting lug between double shackle 6, and section pipe nipple pull rod 5 is most descended to pass through spiral shell
Bolt assembly 9 is connect with the lifting lug 10 at 1 top of microstome trash rack.
When installation, as shown in Fig. 2, the pull rod 2 of the microstome trash rack of this example can pass through the lock on top pipe nipple pull rod 5
Fixed board 7 is located on the locking beam 4 of inspection platform 3 and is locked, specifically when processing, the double shackle 6 of pipe nipple pull rod 5 and single lifting lug
The right angle of 8 bottoms carries out rounding processing, to reduce the machining stress of sharp corner.
