Fig. 3 is the schematic diagram that claw hook device of the present invention carries out submersible sewage pump maintenance.
Specific embodiment
Below by drawings and examples, technical scheme of the present invention will be described in further detail.
Fig. 1 is the schematic diagram of claw hook device of the present invention, as shown, claw hook device of the invention includes: balancing pole 2, rises
Hang connector 4, suspension hook 7, unhook torsional spring 6, balance weight 3 and guide holder 8.
Lifting connector 4 is fixed on balancing pole 2, and suspension hook 7 is connected by suspension hook connecting shaft 5 with lifting connector 4, is taken off
Hook torsional spring 6 is connected with suspension hook 7, and balance weight 3 is socketed on balancing pole 2, slides and is arranged along balancing pole 2；Guide holder 8 is fixed on flat
It weighs on bar 2, guide holder 8 and balance weight 3 set up separately in the two sides of lifting connector 4.
Fig. 2 is the schematic diagram that claw hook device of the present invention carries out submersible sewage pump installation, as shown, being dived with grapple of the present invention
The course of work of dirt pump installation is that coupling flange 11 is installed on submersible sewage pump 12, and external submersible sewage pump 12 is hung on suspension hook 7, is taken off
Hook torsional spring 6 be pressed in lifting junction 10 on, adjustment block 3 make balancing pole 2 balance, lifting machine 1 sling lifting connector 4 to
Submersible sewage pump 12 is sling, flange 11 is coupled along guide rail 9, submersible sewage pump 12 is located to the installation site of cesspool, the steel wire of lifting machine 1
When rope does not stress, suspension hook 7 is detached from submersible sewage pump 12 by unhook torsional spring 6.
Further, balance weight 3 is specially adjustable and balancing block, and guide holder 8 is specially manifold type installation submersible sewage pump guiding
Seat, submersible sewage pump are coupling installation submersible sewage pump.
It is hung on the suspension hook of claw hook device specifically, manifold type is installed the lifting junction on submersible sewage pump, and by grapple
On unhook torsional spring be pressed in coupling installation submersible sewage pump on lifting junction on, according to coupling installation submersible sewage pump on lifting point with lead
Distance between tie rods, for the appropriate adjustable and balancing block adjusted on grapple so that balancing pole balances, coupling is installed submersible sewage pump by starting lifting machine
Coupling installation submersible sewage pump to just, is slowly put into cesspool by guide holder with the guide rod coupled on installation submersible sewage pump, when will couple
When installation submersible sewage pump reaches its installation site, crawl boom hoisting deviates its upright position and steel when the wirerope on boom hoisting
When cord does not stress, suspension hook is just completely disengaged the lifting junction on coupling installation submersible sewage pump by the unhook torsional spring on grapple, then
Grapple is proposed cesspool by secondary starting lifting machine.
Fig. 3 is the schematic diagram that claw hook device of the present invention carries out submersible sewage pump maintenance, as shown, being dived with grapple of the present invention
Dirt pumps the course of work overhauled,
Lifting machine 1 is sling lifting connector 4 and is put into cesspool, by the guide rod 9 on guide holder 8 and submersible sewage pump 12 to just,
Adjustment block 3 is so that guide holder 8 balances, and after suspension hook 7 encounters submersible sewage pump 12, the wirerope on lifting machine 1 is tilted, suspension hook 7
Hang submersible sewage pump 12 and coupling flange 11.
Specifically, the lifting connector on claw hook device is hung on the suspension hook of lifting machine, starting lifting machine puts grapple
Enter in cesspool, by the coupling installation submersible sewage pump guide holder on grapple with the guide rod coupled on installation submersible sewage pump to just, adjustment is grabbed
Adjustable and balancing block on hook, so that the coupling installation submersible sewage pump guide holder balance of part 8 on balancing pole, by lifting machine by grapple
It is slowly put into cesspool, when the suspension hook on grapple is encountered when junction is lifted by crane in the connection on coupling installation submersible sewage pump on lifting machine
Wirerope can become inclination crawl lifting machine at this time, the suspension hook when wirerope on lifting machine becomes straight on grapple is just hung over
Manifold type is installed submersible sewage pump by the lifting junction on coupling installation submersible sewage pump, starting lifting machine, is proposed cesspool and is placed on dirt
Maintenance department in pump house.
The advantages of claw hook device of the present invention, is as follows:
It is compared to the installation on existing installation coupling installation submersible sewage pump, submersible agitator, diving circulating pump, maintenance mode
With its corresponding lifting tie point connection of loop chain, loop chain is for a long time in cesspool, and the time has grown loop chain and wirerope easily exists
Sewage internal corrosion, and grapple is put into cesspool when grapple does not have to be put into cesspool if you need to overhaul installation for a long time, using finishing
It is put in storage afterwards.
Compared to the loop chain of existing coupling installation submersible sewage pump, needed in use when coupling installation submersible sewage pump is in installation, maintenance
Between link, and intermediate partition apparatus need to be installed additional, frequently by the lift hook unhooking on lifting machine, jack, when use is absolutely unsafe, and grabs
Hook does not need then, relative usage safety.
It should be noted last that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although ginseng
It is described the invention in detail according to preferred embodiment, those skilled in the art should understand that, it can be to the present invention
Technical solution be modified or replaced equivalently, without departing from the spirit and scope of the technical solution of the present invention.
