Abstract

The utility model discloses a rolling type damping bed. At two ends of a bed body (5), the bed body (5) is connected with support legs through bolt groups (6) and cushion pads (7), two ends of the upper surface of the bed body (5) are symmetrically and fixedly connected with edge supports (1) with the same height, at least two rib plates (2) are close to the inner sides of the edge supports (1) and are fixedly connected onto four corners of the upper surface of the bed body (5), at least two middle supports (4) with the same height are symmetrically arranged at positions close the middle of the bed body (5), and two ends of at least two impact idlers (3) are movably connected with upper ends between the edge supports (1) and the middle supports (4) and on the upper ends among the middle supports (4) which are arranged symmetrically. Because the at least two impact idlers (3) are arranged neatly and are both arranged between the edge supports (1) and the middle supports as well as between the two middle supports (4), a belt of a conveyor is in uniform contact with the impact idlers (3), a damping effect is enhanced and the service life of a damping bracket is prolonged, and together with the action of the cushion pads (7), a dual-damping effect is achieved. The rolling type damping bed is economic in energy, high in strength and stable in work and has practical and popularization values.

Description

A kind of roller is buffer bed

Technical field

The utility model relates to a kind of buffer bed, and the roller that relates in particular to a kind of band conveyor discharging point place for delivery of granular material or lump material is buffer bed.

Background technology

On the discharging point on the band conveyor, (locate) at present owing to be subject to the intense impact of blanking (such as powdered iron breeze or block coke, white clouds building stones or lime building stones etc.), carrying roller or support group are damaged easily, usually all be provided with shock absorber on the carrying roller at blanking position or support, buffer bed such as impact idler or sliding type is exactly an example for this reason.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 be in vacant state, insufficient strength; Although the buffer bed weak point that overcomes impact idler of sliding type, namely there is good buffering effect that enough intensity is arranged again, but produce cliding friction at belt conveyor with the position that the bed body contacts, bring very large resistance to belt feeder, the propulsion source power that drives belt feeder will strengthen relatively, energy consumption increases like this, and the intensity of other parts also must increase, and has increased holistic cost.

Summary of the invention

The purpose of this utility model be 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, the technical solution adopted in the utility model is: the buffer bed limit support that comprises of described a kind of roller, gusset, impact idler, medium-height trestle, lathe bed, bolt group and cushion rubber, two at lathe bed links to each other lathe bed through bolt group and cushion rubber with support, be fixed with highly identical limit support in the two ends of lathe bed upper surface symmetrical expression, 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 upper end between the symmetrical medium-height trestle.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 is to distribute to organize impact idlers at the bed body more, 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 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 holistic cost.

The specific embodiment

Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.

As shown in drawings, 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, described bolt group 6 is generally bolt and pad (circle) forms, 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 consists of, guaranteed the stability that roller is buffer bed.Lathe bed 5 is linked to each other with leg through bolt group 6 and cushion rubber 7 at two of lathe bed 5, 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 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, by the midway location of lathe bed 5 be arranged symmetrically with quantity greater than medium-height trestle 4, the height of each medium-height trestle 4 is identical, 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 4 that is symmetric is also for being connected with quantity greater than two of 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 consists of the buffer bed of flute profile, because 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 described in the utility model simultaneously.
