Abstract
The utility model relates to a connecting structure for quasi involute powerful pin rails and a middle groove of a scraper conveyer. The connecting structure comprises pin rails which are connected by a pin, and a pin rail base arranged on the middle groove. The connecting structure is characterized in that each pin rail consists of a main side plate (1) and an auxiliary side plate (3) which are connected though pin teeth (2), auxiliary locating platforms (5) are arranged at parts at which the pin rail base is in contact with the two ends of the inner side of the main side plate (1), and the parts at which the auxiliary locating platforms (5) are in contact with the two ends of the inner side of the main side plate (1) are arc-shaped surfaces. The connecting structure provided by the utility model, is suitable for 1500-mm middle groove. The strength of the pin rails is enhanced by 1.5 times than that of the original pin rail with a pitch of 126mm. The variation range of the pitch at the connecting part of the adjacent pin rails can also be controlled.
Description
Technical field
The utility model relates to the connection structure of the powerful pin row of a kind of accurate involute and the middle pan of scraper conveyor.
Background technology
The pin row of coal mine slat conveyer adopts bearing pin to be connected with the pin rail seat in intermediate channel at present.And working surface coal mining machine is walked and realized by traction system on slat conveyer under coal mine, this traction system comprises the electric drive road wheel of coalcutter and the pin row of slat conveyer.Existing 126mm pitch supporting in 1500mm flute length intermediate channel six alligators row moduluses are little, and intensity is low, can not meet that high spud angle is faced upward, underhand stopes coal mining requirement.And because there is larger pitch variation adjacent pin row junction, walking wheel of coal cutter there will be mesh impact at pitch variation place, and can increase like this angle of obliquity in 2 teeth whens engagement, make two tooth engagement processes have larger relative sliding, increase the wearing and tearing to tooth top portion, reduce the service life of pin row and road wheel.
Utility model content
The purpose of this utility model is to provide the connection structure of the powerful pin row of a kind of accurate involute and the middle pan of scraper conveyor, can improve pin row intensity and control the pitch variation scope of adjacent pin row junction.
The connection structure of the powerful pin row of a kind of accurate involute and the middle pan of scraper conveyor, comprise the pin rail seat in pin row and the intermediate channel connecting with bearing pin, its special feature is: wherein pin row is made up of the master plate connecting by pin tooth and secondary side plate, and on pin rail seat with this master plate inside contact position, two ends be equipped with auxiliary positioning platform, and inside this auxiliary positioning platform and master plate, the two ends place of being in contact with one another is circular-arc surface.
Wherein pin tooth has 5.
Wherein the pitch of pin row is 151mm.
Wherein outside the master plate of pin row, two ends are circular-arc surface.
The utility model provides the connection structure of the powerful pin row of a kind of accurate involute and the middle pan of scraper conveyor, be applicable to 1500mm intermediate channel, compared with original 126mm pitch pin row, intensity improves 1.5 times, can also control adjacent pin row junction pitch variation scope.

Detailed description of the invention
As shown in Fig. 1,2,3,4,5, the utility model is the powerful pin row of a kind of accurate involute and the connection structure of planting the middle pan of scraper conveyor, comprise the pin rail seat in pin row and the intermediate channel connecting with bearing pin, wherein pin row is made up of the master plate 1 connecting by 5 pin tooths 2 and secondary side plate 3, and the pitch of pin row is 151mm.On pin rail seat, be equipped with auxiliary positioning platform 5 with this master plate 1 contact position, two ends, inner side, and this auxiliary positioning platform 5 is circular-arc surface with master plate 1 two ends, the inner side place of being in contact with one another.
Master plate 1 two ends, outside 4 of pin row are also circular-arc surface in addition.
Principle of work of the present utility model is:
As shown in Figure 4, generally the minimum pitch of two adjacent pin rows is sizes of intermediate channel minimum pitch L while bending to maximum angle vertically upward, is that locating surface A controls on the lower; And in the utility model, be that the master plate of pin row 1 two ends, outside 4 are to circular-arc surface, can control the minimum pitch L of two adjacent pin rows by the cooperation between two auxiliary positioning circular arcs.
As shown in Figure 5, generally the maximum pitch of two adjacent pin rows is sizes of intermediate channel maximum pitch H while bending to maximum angle vertically downward, and top locating surface B controls; And in the utility model, be to be equipped with auxiliary positioning platform 5 with this master plate 1 contact position, two ends, inner side on pin rail seat, and this auxiliary positioning platform 5 is circular-arc surface with master plate 1 two ends, the inner side place of being in contact with one another, and can control the maximum pitch H of two adjacent pin rows by the cooperation between two auxiliary positioning circular arcs.
