Abstract

The invention relates to a rolling buffer bed. The rolling buffer bed comprises side brackets, rib plates, buffer carrier rollers, middle brackets, a bed body, bolt groups and a buffer cushion, wherein at the two ends of the bed body, the bed body is connected with support legs through the bolt groups and the buffer cushion; the side brackets of the same height are fixedly connected to the two ends of the upper surface of the bed body symmetrically; more than one rib plate is fixedly connected to the four corners of the upper surface of the bed body close to the inner sides of the side brackets; more than one middle bracket of the same height is symmetrically arranged close to the middle of the bed body; the two ends of more than one buffer carrier roller are movably connected to upper ends between the side brackets and the middle brackets and movably connected to upper ends between the middle brackets which are distributed symmetrically. More than one buffer carrier roller is arranged orderly between the side brackets and the middle brackets as well as between the two middle brackets, and a conveyer belt is uniformly contacted with the buffer carrier rollers, thereby enhancing the buffer effect and prolonging the working life of a buffer bracket. Under the action of the buffer cushion, dual buffering effects are achieved.

Description

A kind of roller is buffer bed

Technical field

The present invention relates to a kind of roller buffer bed.

Background technology

On current discharging point on band conveyor, (locating) is owing to being subject to the intense impact of blanking (as powdered iron breeze or block coke, dolomite or lime building stones etc.), carrying roller or support group are easily damaged, conventionally on the carrying roller at blanking position or support, be all provided with shock absorber for this reason, as impact idler or sliding type buffer bed be exactly an example.Described impact idler is to set up a lot of rubber buffer circles at the outside face of steel carrying roller, and its shortcoming is: the thin thickness of rubber buffer ring, and buffering effect is poor, and the carrying roller density of installation is little, makes most of belts all in vacant state, insufficient strength; Although the buffer bed weak point that overcomes impact idler of sliding type, there is good buffering effect to have again enough intensity, but produce cliding friction at belt conveyor with the position that bed body contacts, to belt feeder, bring very large resistance, drive the propulsion source power of belt feeder relatively to strengthen, energy consumption increases like this, and the intensity of other parts also must increase, and has increased holistic cost.

Summary of the invention

The object of this invention is to provide a kind of energy-conservation, intensity is high, the roller of long service life and working stability is buffer bed.

For achieving the above object, technical scheme of the present invention is: a kind of roller is buffer bed, comprise limit support, gusset, impact idler, medium-height trestle, lathe bed, bolt group and cushion rubber, two at lathe bed is connected lathe bed through bolt group and cushion rubber with leg, in the two ends of lathe bed upper surface symmetrical expression, be fixed with highly identical limit support, gusset the fixedlying connected to the inner side on four angles of lathe bed upper surface near limit support that quantity is greater than 1, by the midway location symmetrical expression of lathe bed, be furnished with quantity and be greater than 1 and highly identical medium-height trestle, the two ends that quantity is greater than 1 impact idler are movably connected in the upper end between limit support and medium-height trestle and are movably connected in the upper end between symmetrical medium-height trestle.Wherein the height of limit support is greater than the height of medium-height trestle.

The invention has the beneficial effects as follows: 1. roller described in is buffer bed is many group impact idlers that distributing on bed body, and the spacing between carrying roller and carrying roller is very little, and a bed body itself is linked to be an integral body by shaped steel again, has higher intensity.2. in the outer ring of carrying roller, there is rubber buffer ring, below adapter plate, also have very thick buffer rubber gasket, there is double buffering effect.3. between operation belt and carrying roller, be friction of rolling, resistance is little, for sliding type is buffer bed, energy-conservation, also can reduce the Material Strength of corresponding component, reduces holistic cost.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described.

As shown in the figure, a kind of roller is buffer bed, comprise limit support 1, gusset 2, impact idler 3, medium-height trestle 4, lathe bed 5, bolt group 6 and cushion rubber 7, described bolt group 6 is generally bolt and pad (circle) forms, known technology, and lathe bed 5 is to be greater than the steel plate of 1 marshalling and to be welded on the integral body that the angle steel at steel plate two ends forms by quantity, has guaranteed the stability that roller is buffer bed.Two at lathe bed 5 is connected lathe bed 5 through bolt group 6 and cushion rubber 7 with leg, wherein cushion rubber 7 is to make of elastomeric material, has spring function.Two ends symmetry at lathe bed 5 upper surfaces is fixed with highly identical limit support 1, gusset 2 (triangle) the fixedlying connected to the inner side on four angles of lathe bed 5 upper surfaces near limit support 1 that quantity is greater than 1, by the midway location symmetrical expression of lathe bed 5, be furnished with quantity and be greater than 1 and highly identical medium-height trestle 4, the two ends that quantity is greater than 1 impact idler 3 are movably connected in the upper end of 4 of limit support 1 and medium-height trestle, and the upper end between the medium-height trestle 4 being symmetric is also greater than two of 1 impact idler 3 for being connected with quantity.Because the height of limit support 1 is greater than the height of medium-height trestle 4, so, the impact idler 3 that is connected in the impact idler 3 between limit support 1 and medium-height trestle 4 and is connected between medium-height trestle 4 forms the buffer bed of flute profile, because the impact idler 3 of each monomer is rotatable, therefore it is buffer bed to be referred to as roller, and the belt uniform contact of all impact idlers 3 and conveyer.

During enforcement, by the buffer bed downside place that is installed to belt conveyor blanking of described a kind of roller, when material conveying is fallen on belt conveyor, owing to being friction of rolling between belt conveyor and impact idler 3, reduced resistance, due to the effect of cushion rubber 7, reach double buffering effect simultaneously, realized object of the present invention.
