Because cylinder in use, the peripheral face and the coal seam of the leading flank of toothholder body evagination and pick installation cover, rock front contact and the easiest wearing and tearing, in long-time use, the phenomenon of even appearing dull polish, the too early back of wearing and tearing of pick toothholder can cause the cylinder wearing and tearing even, consequently just lead to the need frequent pick toothholder of renewal of change, and current toothholder all welds on the cylinder, change every time need consume a large amount of manpowers, material resources and financial resources, construction cost is very high, seriously influence the efficiency of construction.
SUMMERY OF THE UTILITY MODEL
The utility model discloses to the technical problem that the troublesome existence is changed to foretell toothholder, provide a reasonable in design, simple structure, low cost and can the new for the large-scale coal-winning machine cylinder of the new toothholder of quick replacement pick toothholder.
In order to achieve the purpose, the utility model discloses a technical scheme do, the utility model provides a cutting pick toothholder for large-scale coal-winning machine cylinder, including being used for fixing the toothholder body on the cylinder, be equipped with the pick installing sleeve that the corresponding cutting pick of confession that the axis extends along the fore-and-aft direction installed on the toothholder body, still be provided with location locking mechanism on the toothholder body, location locking mechanism is including setting up locating hole and the welding locating pin on the cylinder that is close to one side of cylinder at the toothholder body, still be provided with the communicating locking hole with the locating hole on the toothholder body, locking downthehole be provided with the locking bolt with locating pin threaded connection, be provided with the screw hole with locking bolt matched with on the locating pin.
Preferably, the positioning holes are arranged on one side of the tooth holder body at intervals, and the positioning holes are arranged close to two ends of the tooth holder body.
Compared with the prior art, the utility model has the advantages and positive effects that,
1. the utility model provides a large-scale coal-winning machine is pick toothholder for cylinder utilizes location locking mechanism's setting, the effectual welding volume that reduces the pick toothholder, and then has made things convenient for the quick replacement of toothholder, simultaneously, the utility model discloses simple structure, processing are convenient, also can improve on current cylinder, are fit for using widely on a large scale.

in the above figures, 1, a tooth holder body; 11. positioning holes; 12. a locking hole; 2. a tooth holder body; 3. positioning pins; 31. a threaded hole; 4. and locking the bolt.
Detailed Description
In order to make the above objects, features and advantages of the present invention more clearly understood, the present invention will be further described with reference to the accompanying drawings and examples. It should be noted that the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and therefore the present invention is not limited to the limitations of the specific embodiments of the present disclosure.
Therefore, the cutting pick holder for the large-scale coal mining machine roller provided by the embodiment comprises a holder body 1 fixed on the roller, wherein the holder body 1 is provided with a cutting pick mounting sleeve 2, the axis of which extends along the front-back direction and is used for mounting a corresponding cutting pick, the above structure is common to the existing cutting pick holder, and therefore, in the embodiment, detailed description is omitted.
The key modified place of this embodiment lies in, still be provided with location locking mechanism on current toothholder body 1, specifically speaking, location locking mechanism is including setting up locating hole 11 and the locating pin 3 of welding on the cylinder in one side that toothholder body 1 is close to the cylinder, in this embodiment, locating pin 3 wholly is the cuboid form, it welds on the cylinder, locating hole 11 also becomes square setting, of course, locating pin 3 also can be cylindricality or other shapes, locating pin 3 has two effects, one is convenient quick location fixed, traditional toothholder is when changing, need use positioning device to fix a position the back, just can the welding installation, and simultaneously, when the welding, also need special tight setting of clamp to press from both sides tightly, and through the setting of locating pin 3, then directly with the toothholder body 1 that changes down insert on locating pin 3 can.
In order to realize internal fixation, still be provided with on toothholder body 1 with the communicating locking hole 12 of locating hole 11, locking hole 12 sets up on the side of the opposite side of toothholder body 1, be provided with in locking hole 12 with 3 threaded connection's of locating pin locking bolt 4, be provided with on locating pin 3 with locking bolt 4 matched with screw hole 31, thus, through locking bolt 4's fixed, make toothholder body 1 and cylinder form an organic whole structure, like this, again with toothholder body 1 with the cylinder welding together can, welding thickness is less than traditional welding thickness far away and can ensure fixed stability, and then practiced thrift a large amount of time.
In order to ensure the stability of the fixing, in the present embodiment, the positioning holes 11 are provided at intervals on one side of the carrier body 1, specifically, two positioning holes 11 are provided in total, and the positioning holes 11 are provided near both ends of the carrier body 1.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in other forms, and any person skilled in the art may use the above-mentioned technical contents to change or modify the equivalent embodiment into equivalent changes and apply to other fields, but any simple modification, equivalent change and modification made to the above embodiments according to the technical matters of the present invention will still fall within the protection scope of the technical solution of the present invention.
