Abstract
The utility model provides a disassembling tool of transmission chains used for rapidly and easily replacing the chains, belonging to the technical field of the mechanical industry special-purpose tool. In the technical scheme, the utility model comprises two clip feet, a screw rod and an adjusting hand wheel, wherein one clip foot is fixed and the upper end is in fixed connection with the screw rod, the other clip foot is movable and the upper end is sleeved on the screw rod; the adjusting hand wheel matches with the threads of the screw rod. The special-purpose tool for disassembling chains can be used for rapidly and easily replacing the chains and can greatly mitigate the labor intensity of workers.
Description
Technical field
The utility model relates to a kind of dismantling device that is used for driving chain, belongs to mechanical industry specific purpose tool technical field.
Background technology
Chain drive is as a kind of kind of drive of extensive use, its transmission efficiency height, and the physical dimension compactness, the tensioning regulated quantity is little, and is strong to the adaptive capacity of environment, can work under high temperature, greasy dirt, many dirt, flammable atmosphere.Especially being widely used in fields such as the hot-rolled coil transportation system of metallurgy industry, shaped steel cold bed equipment.But it is very difficult to change chain impaired or that elongate, and especially heavily loaded roller-way chain is very difficult when manually changing.Concrete substitute mode is, with iron wire two pitch chain of chain joint tied together earlier and tightens, and butt joint clamp bearing pin is not stressed, and sticks up split pin, takes out butt chain, and iron wire is unclamped once more, unloads lower chain.When adorning new chain, with iron wire two pitch chain of chain joint are tied together and to tighten, butt chain is plugged, load onto connecting plate and bayonet lock, the iron wire that comes loose resumes operation equipment.This substitute mode wastes time and energy, and is difficult to satisfy the current allegro mode of production.
The utility model content
For the replacing that makes chain becomes more quick, light, the utility model provides a kind of specific purpose tool of chain dismounting.This instrument can not only shorten changes the used time of chain, and can alleviate attendant's labour intensity.
The technical scheme that its technical problem that solves the utility model adopts is:
A kind of dismantling device that is used for driving chain, comprise two card bases, screw mandrel and adjusting handles in the composition, one of them card base is fixing card base, fixedly fixedly connected with screw mandrel in the upper end of card base, another card base is mobile card base, the upper end of mobile card base is sleeved on the screw mandrel, and the screw thread on adjusting handle and the screw mandrel is complementary.
The dismantling device of above-mentioned driving chain is provided with wear-resistant gasket between described mobile card base and adjusting handle.
The dismantling device of above-mentioned driving chain is on described screw mandrel, along the gathering sill that is axially arranged with of screw mandrel.
The dismantling device of above-mentioned driving chain, the circular arc that is complementary for roller in the inboard, lower end of described fixedly card base and mobile card base with chain.
The beneficial effects of the utility model are, make to change chain and become lighter, quick, alleviate working strength of workers greatly.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model schematic diagram;
Fig. 2 is that the utility model is used schematic diagram.
1. screw mandrels among the figure, 2. fixing card base 3. moves card base, 4. adjusting handle, 5. wear-resistant gasket, 6. gathering sill, 7. chain, 8. connecting plate, 9. clamp.
The specific embodiment
In Fig. 1, screw mandrel 1 one ends link to each other with fixing card base 2, and mobile card base 3 can move along gathering sill 6, and wear-resistant gasket 5 reduces the friction that adjusting handles 4 produce when rotating and during mobile card base 3, prevents jam; The design of gathering sill 6 can guarantee that mobile card base 3 does not rotate when moving forward and backward, all the time with fixing card base 2 in one plane.
In an example shown in Figure 2, before changing chain, regulate mobile card base 3 and make that fixedly the distance of card bases 2 and mobile card base 3 is about 3 to 5 times of pitches according to the adjusting handle 4 of the pitch rotating link chain dismantling device of changing chain 7.With fixedly card base 2 and mobile card base 3 insert the both sides of inserting the chain joint respectively, the chain tension of adjusting handle 4 until two card base Outboard Sections turns clockwise, the chain of inside part is lax, and this is just can take off clamp 9 and connecting plate 8 easily, and at this moment chain 7 disconnects from the junction, be rotated counterclockwise adjusting handle 4, mobile card base 3 moves thereupon, and chain is lax, takes off the chain dismantling device, the chain of following machine is removed, and dismounting finishes.Order when new chain is installed is opposite with disassembly sequence.
