The utility model discloses a set up the handle hole on the cover body to through the sealed handle hole of casing head, need not to lift off the guard shield during maintenance, only need open the casing head, utilize the handle hole just can observe the state of inside cylinder screw, and maintain the cylinder screw, alleviateed the work degree of difficulty that whole guard shield was lifted off to original needs greatly, saved maintenance time, improved maintenance efficiency.
Description
Technical field
The utility model relates to cutting drum, is exactly a kind of cutting drum guard shield.
Background technology
At present, the cutting drum diameter of MG650/1515-WD coal-winning machine reaches 2.5m, use procedure intermediate roll screw often loosens, fastening cylinder screw very not easily, needs to be stopped by coal-winning machine to safeguard to upper head place, because drum shield quality is very large, need more than four people to coordinate to be pulled down by drum shield rear just to check and fastening, after checking fastening completing, four people are good and sound by drum shield again, fastening firm.Guard shield set bolt is in the process of often opening and installing, and end button is yielding, causes guard shield fixing loosely; The fastening of cylinder screw was both wasted time and energy, and cost is high, and the operating process amount of labour is large, abnormally dangerous again, very unfavorable to safety in production.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of cutting drum guard shield, and this shield structure is simple, uses convenient operating maintenance, safeguards required artificial few, dangerous little, can improve maintenance efficiency.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of cutting drum guard shield, comprise cover body, cover body is provided with handle hole with cylinder screw corresponding position, and the aperture of handle hole is greater than the diameter of the nut of cylinder screw; Handle hole is provided with casing head, casing head seal operation hole.
Adopt the utility model of technique scheme, compared with prior art, its beneficial effect is:
By in cover body setting operation hole, and by casing head seal operation hole, without the need to unloading lower shield during maintenance, only need to open casing head, utilize handle hole just can observe the state of internal cylinder screw, and cylinder screw is safeguarded, significantly reduce the work difficulty originally needing to unload whole guard shield, save maintenance time, improve maintenance efficiency.
As preferably, the utility model further technical scheme is:
Described handle hole place is provided with the anti-loose wire hole of casing head, casing head anti-loose wire hole connection anti-loose bolt, and locking pin is connected by clamping silk with casing head.By arranging locking pin, can prevent in the guard shield course of work, the casing head at handle hole place loosens, and causes casing head to drop, and improves the sealing performance of casing head.
Described locking pin and casing head are equipped with connecting hole, and locking pin and casing head are connected and fixed by connecting hole by pincers silk.By the mode of pincers silk mechanical connection, locking pin and casing head are connected and fixed, connected mode is succinct, and can repeatedly recycle above-mentioned parts and mode connects, and reduces equipment cost further.
Described cover body is provided with guard shield fixing hole, the anti-porosity of guard shield, guard shield set bolt is provided with in guard shield fixing hole, cover body is connected with coal mining machine roller by guard shield set bolt, and connection anti-loose bolt in the anti-porosity of guard shield, locking pin is connected by clamping silk with guard shield set bolt.
Locking pin is connected by clamping silk with guard shield set bolt, can increase the stability that guard shield is connected with cutting drum further, and prevent in the guard shield course of work, guard shield set bolt unclamps or even drops.
Described locking pin is connected in " ∞ " font mode by clamping silk with casing head, and such connected mode makes locking pin be associated with the state of unclamping of another parts with screwing of first parts of sleeve pipe, unclamps with simple connected mode peventing member.
Described cover body surface is provided with mounting groove, handle hole, anti-loose wire hole, guard shield fixing hole are all arranged in mounting groove, and the degree of depth of mounting groove is greater than the height of the height of the casing head in handle hole, the height of the nut of locking pin, the nut of guard shield set bolt respectively.Casing head, locking pin, guard shield set bolt screw rear being all in mounting groove, can not expose, can effectively avoid above-mentioned connector in the course of the work with other object generation scratchings, cause they deteriorate, lose.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Description of reference numerals: 1-cover body; 2-handle hole; The anti-loose wire hole of 3-casing head; 4-guard shield fixing hole; The anti-porosity of 5-guard shield; 6-mounting groove.
Detailed description of the invention
Below in conjunction with embodiment, further illustrate the utility model.
See Fig. 1, a kind of cutting drum guard shield, is made up of cover body 1 and the connector be arranged on cover body 1, and cover body 1 and cylinder screw corresponding position are provided with handle hole 2, and the aperture of handle hole 2 is greater than the diameter of the nut of cylinder screw; Handle hole 2 is provided with casing head, and casing head seal operation hole 2, casing head is threaded with handle hole 2.
Handle hole 2 place is provided with the anti-loose wire hole 3 of casing head, casing head anti-loose wire hole 3 connection anti-loose bolt, and locking pin is connected by clamping silk with casing head.By arranging locking pin, can prevent in guard shield 1 course of work, the casing head at handle hole 2 place loosens, and causes casing head to drop, and improves the sealing performance of casing head.
Locking pin and casing head are equipped with connecting hole, and locking pin and casing head are connected and fixed by connecting hole by pincers silk.By the mode of pincers silk mechanical connection, locking pin and casing head are connected and fixed, connected mode is succinct, and can repeatedly recycle above-mentioned parts and mode connects, and reduces equipment cost further.
Cover body 1 is provided with guard shield fixing hole 4, the anti-porosity 5 of guard shield, guard shield 1 set bolt is provided with in guard shield fixing hole 4, guard shield 1 is connected with coal mining machine roller by guard shield 1 set bolt, and connection anti-loose bolt in the anti-porosity 5 of guard shield, locking pin is connected by clamping silk with cover body 1 set bolt.
