Abstract
The utility model relates to a connecting chain ring, in particular to a mine round-link chain inserting plate type connecting chain ring. In order to the overcome the shortcoming in the prior art, the mine round-link chain inserting plate type connecting chain ring is simple and reasonable in structure, convenient to disassemble and assemble, reliable in chain connecting and long in service life. The technical scheme is that the mine round-link chain inserting plate type connecting chain ring comprises two half chain rings and an inserting plate. The two half chain rings are both provided with tenons, and the two haft chain rings are meshed with each other to form a whole through the tenons. The adjoining face of the tenons of the two half chain rings is a smooth face, the upper end face of the whole which is formed by the fact that the two half chain rings are meshed with each other through the tenons is provided with a long hole which is communicated with all the tenons, and the inserting plate which is used to connect and fix the two half chain rings is arranged inside the long hole. The mine round-link inserting plate type connecting chain ring is used for a mine scraper plate conveyor.
Description
Technical field
The utility model relates to a kind of chain ring, is specifically related to a kind of circle chain of mine spile type chain ring.
Background technique
Circle chain of mine is widely used on the mine flight conveyer of various models.The chain ring that is used in the market the link hoop chain mainly contains several modes that are connected with a joggle of sawtooth pattern, terraced flute profile and curved tooth type, and they all adopt the plug-in mounting bearing pin to be connected and fixed, but because coal mine environment is complicated, moist, dust is large, bearing pin joint Chang Yinwei dust is cementing or get rusty and stuck, the dismounting difficulty wastes time and energy during replacing, and working life is short; Simultaneously because chain ring adopts tooth to connect, tooth when heat treatment, the bad control of the hardness of tooth, the too hard easily fracture of tooth causes hoop chain to disconnect, the too soft easy distortion of tooth causes the bad dismounting of chain ring, this produces to the colliery and brings a lot of troubles.
The model utility content
The utility model overcomes the deficiency that prior art exists, and technical problem to be solved has provided that a kind of simple and reasonable, easy accessibility, link are firm, the circle chain of mine spile type chain ring of long service life.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: circle chain of mine spile type chain ring, comprise: two and half chain links and plate, described two halves chain link is provided with tenon, and the two halves chain link is meshed by tenon and consists of an integral body, the mating face of tenon is smooth surface in the described two halves chain link, and the upper-end surface of the integral body that consists of of two halves chain link engagement is provided with the slotted hole that runs through all tenons, is provided be used to the plate that is connected and fixed the two halves chain link in the described slotted hole.
The length direction of described slotted hole parallels with the center line of the integral body that the engagement of two halves chain link consists of.
The center of the integral body that described two halves chain link engagement consists of is provided with pin shaft hole, is provided with in the described pin shaft hole for the bearing pin of fixing and run through plate.
The beneficial effect that the utility model compared with prior art has is: half chain link utilizes the tenon engagement in the utility model, and the mating face is smooth surface, guarantee the chain ring easy accessibility, and the two halves chain link is connected and fixed by plate, the plate shear strength is strong, guarantee the hoop chain link robust, simultaneously plate heat treatment is easy, or adopts preferably plate of material, can reach requirement of strength, use more simple and convenient, long service life.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the plan view of Fig. 1.
Fig. 3 is the structural representation of half chain link in the utility model.
Among the figure: 1 is half chain link, and 2 is plate, and 3 is tenon, and 4 is slotted hole, and 5 is pin shaft hole, and 6 is bearing pin.
Embodiment
Such as Fig. 1, Fig. 2, shown in Figure 3, circle chain of mine spile type chain ring, comprise: two and half chain links 1 and plate 2, described two halves chain link 1 is provided with tenon 3, and two halves chain link 1 is meshed by tenon 3 and consists of an integral body, the mating face of tenon 3 is smooth surface in the described two halves chain link 1, and the upper-end surface of the integral body that consists of of two halves chain link 1 engagement is provided with the slotted hole 4 that runs through all tenons 3, is provided be used to the plate 2 that is connected and fixed two halves chain link 1 in the described slotted hole 4.
The length direction of described slotted hole 4 parallels with the center line of the integral body that 1 engagement of two halves chain link consists of.
The center of the integral body that described two halves chain link 1 engagement consists of is provided with pin shaft hole 5, is provided with in the described pin shaft hole 5 for the bearing pin 6 of fixing and run through plate 2.
When the utility model specifically uses, hoop chain snaps in the chain link of two halves chain link 1 by the space between the tenon 3 in the two halves chain link 1 respectively, then two halves chain link 1 is by tenon 3 docking engagements, plate 2 is inserted in the slotted hole 4, and by bearing pin 6 that plate 2 is fixing, guarantee not play in slotted hole 4 of plate 2, and the mating face of tenon 3 is smooth surface, so that the utility model easy accessibility, simultaneously whole processing is simple, only need utilize line to cut into two and half chain links 1 and get final product, operate also simple, and plate 2 heat treatments are easy, perhaps selection material preferably plate can reach the shearing strength requirement, working life is also long.
The above has done detailed description to embodiment of the present utility model by reference to the accompanying drawings, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skills possess, can also under the prerequisite that does not break away from the utility model aim, make various variations.
