Abstract
The utility model provides a kind of power shovel dog great wheel, belongs to extractive equipment technical field, solves the problem of traditional dog great wheel structure design is unreasonable, and complex structural designs, cost is high, and cost of labor is big.It is main to include dog great wheel main body, the grooving of gear rope block is welded with the outside of port, gear rope block is provided with the unthreaded hole for assembling screw rod.Gear rope block structure in new dog great wheel is simple, small, intensity is hardly damaged or comes off greatly, effectively prevents rope is outer greatly to alter；Screw rod is spare part in common, is replaced simply, and only aerobic gas, acetylene cutting screw rod, highly practical, can be widely applied to extractive equipment technical field.
Description
Technical field
A kind of power shovel dog great wheel is the utility model is related to, belongs to extractive equipment technical field.
Background technology
Lifting in traditional power shovel dog great wheel fixing device of restricting greatly is to prevent from restricting greatly by fixed block or mobile fixed block
Alter outside, or rely on assembling screw rod at grooving port, altered effectively to prevent from being lifted outside big rope, but it has one to lack jointly
Point is that planform is more complicated, and spare part needs oneself making and bothersome while fragile or come off, and replacement frequency is high, when and occur
Without spare part, cause all to prevent from altering outside restricting greatly using welding block during field maintenance, gas cutting have to be taken when lifting is big to restrict by replacing
Block, the damage of dog great wheel grooving is easily led to after multiple welding, gas cutting.
Utility model content
The purpose of this utility model is to provide a kind of power shovel dog great wheel, overcomes above-mentioned deficiency of the prior art, effectively
Prevent from being lifted and altered outside big rope, eliminate the big rope fixing device spare part phenomenon not easy to be processed of dog great wheel, while avoid dog great wheel from repeating
Weld and cause dog great wheel grooving to damage.
The technical solution of the utility model is：A kind of power shovel dog great wheel, including dog great wheel main body, grooving, gear rope block, spiral shell
Bar, respectively there is a grooving before and after the dog great wheel main body, and the grooving is semicircle shape, and gear rope is provided with the outside of grooving port
Block, the gear rope block are equipped with endoporus, and the endoporus is used to assemble screw rod.
Further, the gear rope block is steel plate, and the thickness of gear rope block is 40-50mm.
Further, the internal diameter of the endoporus is 18-30mm.
Further, the grooving, gear rope block, screw rod form an entirety using electric welding and dog great wheel main body.
The beneficial effects of the utility model are：Gear in this utility model dog great wheel lifts that big rope device is simple in structure, body
Product is small, intensity is hardly damaged or comes off greatly, effectively prevents from being lifted and is altered outside big rope；Screw rod is spare part in common, replaces simply, avoids
Spare part lacks, while prevents grooving from being damaged because of Rewelding, cutting block, and production cost is greatly lowered, highly practical, can
It is widely used in extractive equipment technical field.
Brief description of the drawings
Fig. 1 is the utility model main structure diagram；
Fig. 2 is the utility model overlooking the structure diagram；
Fig. 3 is the utility model left view structural representation.
In figure：1. dog great wheel main body；2. gear rope block；3. endoporus；4. grooving；5. screw rod.
Embodiment
The utility model is described in further detail below in conjunction with attached drawing, it is a kind of according to Fig. 1, Fig. 2 and Fig. 3
Power shovel dog great wheel, including dog great wheel main body 1, grooving 4, gear rope block 2, screw rod 5, respectively have one before and after the dog great wheel main body 1
Grooving 4, the grooving 4 are semicircle shape；Gear rope block 2 is provided with the outside of 4 port of grooving, the gear rope block 4 is equipped with endoporus 3, institute
Endoporus 3 is stated to be used to assemble screw rod 5.
A kind of power shovel dog great wheel, gear rope block 2 is steel plate.
A kind of power shovel dog great wheel, gear rope block 2 will reach certain intensity, thickness 40-50mm.
A kind of power shovel dog great wheel, a diameter of 18-30mm of endoporus 3,5 diameter of screw rod are slightly less than endoporus 3.
A kind of power shovel dog great wheel, grooving 4, gear rope block 2, screw rod 5 are formed using electric welding and dog great wheel main body 1
One entirety.
The utility model includes dog great wheel main body 1, and the dog great wheel front and back middle position is fixed with semicircle
Grooving 4, tells and gear rope block 2 is fixed with the outside of 4 port of grooving, and the gear rope block 2 is equipped with endoporus 3, when the big rope rope of lifting is embedding
Enter in grooving 4, the movement of dog great wheel main body 1 is driven by lifting big rope rope, assembling screw rod 5, primarily serves and keep out in endoporus 3
The outer effect altered of the big rope of lifting.
