Abstract

The utility model relates to a carrier roller set used for lifting and supporting a conveyor belt and aims at providing a carrier roller set which is simple in structure, convenient to install, and capable of effectively conveying coal upwards and preventing gangue from rolling off. The deep groove carrier roller set comprises a groove type support which comprises a left branch support and a right branch support, wherein the left branch support and the right branch support are symmetric in a left-and-right mode along the perpendicular bisector of the bottom of a groove, the corresponding position of the front end face of the left branch support and the corresponding position of the front end face of the right branch support are respectively provided with a first carrier roller in a hinged mode, and the corresponding position of the rear end face of the left branch support and the corresponding position of the rear end face of the right branch support are respectively provided with a second carrier roller in a hinged mode. The two first carrier rollers are symmetric in a left-and-right mode along the perpendicular bisector of the bottom of the groove, and the two second carrier rollers are symmetric in a left-and-right mode along the perpendicular bisector of the bottom of the groove. The left end of the first carrier roller on the left branch support and the right end of the second carrier roller on the left branch support are overlapped or crossed in terms of projections in the envisaging direction. The included angle of the two axes of the two first carrier rollers is 140 degrees to 160 degrees, and the included angle of the two axes of the two second carrier rollers is 50 degrees to 70 degrees. According to the carrier roller set, the two carrier roller sets are arranged, and the inclined angles of the two carrier roller sets are sequentially increased, the depth of the groove is increased, and the carrying capacity of the conveyor belt is enhanced.

Description

Deep trouth carrying roller group

Technical field

The utility model relates to a kind of conveyer, particularly relates to a kind of for delivery of machine carrying roller group.

Background technology

Belt conveyer is widely used in coal mining, some regional mine laneway inclination angle is very large, local reachability to 25 degree, the coupling type Hinge linked supporting roller group that they adopt only has three carrying rollers to form, and becoming groove angle (groove angle is axis and the horizontal angle of carrying roller) only is 30 degree or 35 degree, in the transportation that makes progress of coal, often occur rolling the phenomenon that fortune is not gone out under lubricating substance and the spoil like this, affected normal production and the very large potential safety hazard of existence on the ore deposit.

The utility model content

The technical matters that the utility model deep trouth carrying roller group will solve provides and a kind ofly can adapt to the high spud angle tunnel, and simple in structure firm, easy for installation, the carry coal that can effectively make progress also prevents the carrying roller group that spoil tumbles.

The utility model deep trouth carrying roller group, comprise Troffer, described support comprises along the bottom land midperpendicalar left, the parting support on the left side and part support on the right side of right symmetry, describedly part support on the left side and part each hinged first carrying roller on the support front end face correspondence position on the right side, describedly part support on the left side and part each hinged second carrying roller on the support aft end face correspondence position on the right side, described two first carrying rollers are left along described bottom land midperpendicalar, right symmetry, described two second carrying rollers are left along described bottom land midperpendicalar, right symmetry, described part on the left side on the support the first carrying roller left end and described part on the left side on the support the second carrying roller right-hand member face on the direction projection overlapping or crossing, two axis angles of described two first carrying rollers are 140 °～160 °, and two axis angles of described two second carrying rollers are 50 °～70 °.

Compared with prior art basis is practical is comprised of four carrying rollers, and symmetrical in twos, part on the left side two carrying rollers are set on the support, be divided into the first carrying roller and the second carrying roller, part on the right side two carrying rollers also are set on the support, also be the first carrying roller and the second carrying roller, two the first carrying rollers are in the inboard, two the second carrying rollers are in the outside, two axis angles of two first carrying rollers are 140 °～160 °, and two axis angles of two second carrying rollers are 50 °～70 °, have effectively increased groove depth, actv. has solved that coal upwards transports difficulty and spoil easily tumbles problem, has improved the carrying capacity of load-transfer device.

The utility model deep trouth carrying roller group, two axis angles of wherein said two first carrying rollers are 150 °, two axis angles of described two second carrying rollers are 60 °, through actual verification repeatedly, adopt above-mentioned angle effect best, and the carrying capacity of load-transfer device is strengthened.

Below in conjunction with accompanying drawing the utility model deep trouth carrying roller group is described further.

Fig. 2 is the utility model deep trouth carrying roller group birds-eye view.

The specific embodiment

As shown in Figures 1 and 2, the utility model deep trouth carrying roller group comprises Troffer, support comprises along the bottom land midperpendicalar left, the parting support 11 on the left side and part support 12 on the right side of right symmetry, part support 11 on the left side and part each hinged first carrying roller 31 on the support 12 front end face correspondence positions on the right side, part support 11 on the left side and part each hinged second carrying roller 32 on the support 12 aft end face correspondence positions on the right side, two the second carrying rollers 32 are arranged on two the first carrying roller 31 outsides, two first carrying rollers 31 are left along the bottom land midperpendicalar, right symmetry, two second carrying rollers 32 are left along the bottom land midperpendicalar, right symmetry, two axis angles of two first carrying rollers 31 are 140 °～160 °, and two axis angles of two second carrying rollers 32 are 50 °～70 °.

The utility model in use, with some the utility model longitudinal arrangements, as a kind of optimal way of the present utility model, two axis angles of the utility model two first carrying rollers 31 are 140 °, 150 °, 160 °, two axis angles of two second carrying rollers 32 are 50 °, 60 °, 70 °, the upper surface covers load-transfer device, because the first carrying roller 31 and the second carrying roller 32 symmetries, and increased successively by inner reaching outward with the angle of horizontal direction, actv. has increased groove depth like this, strengthen belt conveyance and anti-lubricating substance ability, improved load-transfer device and transported efficient.

Above-described embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of the utility model claims.
