Abstract

The invention discloses a rolling type buffer bed. A bed body (5) is connected with supporting legs through a bolt set (6) and a buffer pad (7) at the two ends of the bed body (5); side brackets (1) with the same height are symmetrically and fixedly connected at the two ends on the upper surface of the bed body (5); more than one rib plate (2) is close to the inner side of each side bracket (1) and fixedly connected to the four corners on the upper surface of the bed body (5); more than one middle bracket (4) with the same height is symmetrically arranged in the middle close to the bed body (5); and the two ends of each of more than one buffer supporting roller (3) are movably connected to the upper end between each side bracket (1) and each middle bracket (4) and the two ends of each buffer supporting roller are movably connected to the upper end between the symmetrically distributed middle brackets (4). The more than one buffer supporting roller (3) is regularly mounted between each side bracket (1) and each middle bracket (4) and between the two middle brackets, so that a conveyer belt is uniformly in contact with the buffer supporting rollers (3), the buffer effect is enhanced, the working life of the buffer supporting rollers (3) is prolonged, and the dual-buffer effect is achieved due to the effect of the buffer pad (7). Therefore, the rolling type buffer pad is energy-saving, high in strength and stable in operation, and has practical and promotional values.

Description

A kind of roller is buffer bed

Technical field

The present invention relates to a kind of buffer bedly, the roller that relates in particular to a kind of band conveyor discharging point place that is used for conveying powder material or lump material is buffer bed.

Background technology

On the discharging point on the band conveyor, (locate) at present owing to receive the intense impact of blanking (like powdered iron breeze or block coke, white clouds building stones or lime building stones etc.); Carrying roller or groups of holders are damaged easily; Usually on the carrying roller at blanking position or support, all be provided with shock absorber, buffer bed like impact idler or sliding type is exactly an example for this reason.Said impact idler is to set up a lot of rubber bumper rings 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 be in vacant state, insufficient strength; Though the buffer bed weak point that overcomes impact idler of sliding type; Promptly there is good buffering effect that enough intensity is arranged again, but produces cliding friction with the position that the bed body contacts, bring very big resistance to belt feeder at belt conveyor; The propulsion source power of driving belt machine will strengthen relatively; Energy consumption increases like this, and the intensity of other parts also must increase, and has increased whole cost.

Summary of the invention

The object of the present 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 realizing above-mentioned purpose; The technical scheme that the present invention adopts is: buffer bed limit support, gusset, impact idler, medium-height trestle, lathe bed, bolt group and the cushion rubber of comprising of described a kind of roller; Two at lathe bed links to each other lathe bed through bolt group and cushion rubber with support; Symmetrical expression is fixed with highly identical limit support in the two ends of lathe bed upper surface; Quantity is greater than 1 gusset fixedlying connected to the inner side on four angles of lathe bed upper surface near the limit support; Be furnished with quantity greater than 1 and highly identical medium-height trestle near the midway location symmetrical expression of lathe bed, quantity is movably connected in the upper end between limit support and the medium-height trestle greater than the two ends of 1 impact idler and is movably connected in the upper end between the medium-height trestle of symmetrical distribution.Wherein the height of limit support is greater than the height of medium-height trestle.

Adopt a kind of roller buffing pad that as above technical scheme provides compared with prior art, technique effect is:

1. described roller is buffer bed to be many group impact idlers that on the bed body, distributing, and the spacing between carrying roller and carrying roller is very little, and 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 rubber buffer ring is arranged, below adapter plate, also have very thick buffer rubber gasket, have the double buffering effect.

3. moving between belt and carrying roller is friction of rolling, and resistance is little, and is energy-conservation for sliding type is buffer bed, also can reduce the Material Strength of corresponding component, reduces whole cost.

The specific embodiment

Do further to describe in detail below in conjunction with the accompanying drawing specific embodiments of the invention.

Shown in accompanying drawing; Buffer bed limit support 1, gusset 2, impact idler 3, medium-height trestle 4, lathe bed 5, bolt group 6 and the cushion rubber 7 of comprising of described a kind of roller; Said bolt group 6 is generally bolt and pad (circle) is formed; Known technology, and lathe bed 5 be by quantity greater than the steel plate of 1 marshalling and be welded on the integral body that the angle steel at steel plate two ends constitutes, guaranteed the stability that roller is buffer bed.Link to each other lathe bed 5 with leg through bolt group 6 and cushion rubber 7 at two of lathe bed 5, wherein cushion rubber 7 is to make with elastomeric material, has spring function.Two ends symmetry at lathe bed 5 upper surfaces is fixed with limit support 1; The height of each limit support 1 is identical; Quantity is greater than 1 gusset 2 (triangle) fixedlying connected to the inner side on four angles of lathe bed 5 upper surfaces near limit support 1; Lean on the midway location symmetric arrangement of lathe bed 5 have quantity greater than medium-height trestle 4; The height of each medium-height trestle 4 is identical, and quantity is movably connected in the upper end of limit support 1 and medium-height trestle 4 greater than two of 1 impact idler 3, and the upper end between the medium-height trestle that is symmetrical distribution 4 is also for being connected with quantity two greater than 1 impact idler 3.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 the medium-height trestle 4 and is connected between the medium-height trestle 4 constitutes the buffer bed of flute profile; Because of the impact idler 3 of each monomer is rotatable, so it is buffer bed to be referred to as roller, and the belt uniform contact of all impact idlers 3 and conveyer.

During enforcement; With the buffer bed downside place that is installed to the belt conveyor blanking of described a kind of roller, when material conveying is fallen on the belt conveyor, owing to be friction of rolling between belt conveyor and the impact idler 3; Reduced resistance; Because the effect of cushion rubber 7 has reached the double buffering effect, realized purpose of the present invention simultaneously.
