Description

A kind of hollow rubber for filling resilient material is buffer bed

Technical field

The utility model belongs to material transport technique field, and in particular to a kind of hollow rubber for filling resilient material is slow Punching machine.

Background technique

Buffer bed and buffer bar reduces energy consumption by German engineer, improves material transfer efficiency originating from Germany And utility model, originally buffer bed and buffer bar design pattern are more, the seventies, connection structure was mainly aluminium alloy connection side Formula, length can also continuously adjust, but with the demand that practical application and mining industry underground use, connection structure is gradually It is substituted by steel structure, German engineer finds that aluminium alloy rigidity is not strong in practical application, and the play of buffer bar is existing frequent occurrence As situation seriously leads to the tearing of conveyer belt, and most important is that underground is forbidden to use aluminum alloy materials in the world, any Using aluminum alloy connection structure in underground using there is potential security risk, therefore starts German engineer in the nineties and adopt With steel structure connection type.

In the prior art, the buffer bed blanking position for being primarily used for belt conveyor, plays the role of material buffer, Impact force when material falls is greatly reduced, the force-bearing situation of discharging point is veritably improved, has reached protection conveyer belt Purpose.However complex process when the production of conventional buffer bed, as shown in Fig. 1, the heat cure polyphosphazene polymer on elastomer layer 1-2 Vinyl plate 1-1 is mounted on support frame 1-3 after integrally vulcanizating, but this manufacturing cost is high, and needs vulcanizing equipment and ring Guarantor's measure seriously affects and transports material effect and service life.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than all Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise Under every other embodiment obtained, fall within the protection scope of the utility model.It additionally, should not be by the utility model Protection scope only limit to following specific structures or component or design parameter.

The hollow rubber of the filling resilient material of the utility model as shown in Figure 2 is buffer bed comprising hollow buffering Item 1 and support frame, wherein with connector 103(preferred bolt) clamping of hollow buffer bar is mounted in channel steel inside groove 104, it connects Part 103 runs through the side wall of channel steel inside groove 104, and connector 103 is T-shaped shape, and the end T is located inside, in the end T of connector 103 It is isolated between side and hollow buffer bar using resilient sleeper-bearing 102, to realize preferably fastening and sealing；The outer end of connector 103 It is fixed using fastening nut 106 in the outer end of connector 103 through the side wall of channel steel inside groove 104.Hollow buffer bar is in semicircle Shape, hollow buffer bar use elastic plastic material；Its preferred selection waste old band is made.

As shown in figure 3, be fixed together by tight joints with channel steel inside groove at the flanging of hollow buffer bar, it is hollow Two flangings of buffer bar are fixed with the both sides of channel steel inside groove respectively respectively.Preferably, using the hollow buffer bar of bilayer or multilayer, (bottom end junction) 107 is tightly connected at the flanging of two layers of hollow buffer bar.For example, the first hollow buffer bar 101A and second is empty Region 101B between heart buffer bar 101B is hollow；Further, in the hollow region constituted between adjacent hollow buffer bar Flowability elastic material (for example, generally filling industrial silicone in actual production, or the anti-oxidant water of filling) is filled, preferably Ground, the area filling flowability elastic material formed between the hollow buffer bar 101C of innermost layer and channel steel inside groove 104 (for example, Fine sand, preferred size are the fine sand of 20-40 mesh), five times or more of service life of hollow buffer bar can be extended in this way.

Further, in hollow rubber as shown in Figure 2 is buffer bed, support frame includes support baseboard 4,3 and of support rod Supporting arc plate 2, the supporting arc plate are supported on support baseboard by support rod, when support baseboard 4 is horizontal direction, support Bar 3 includes two or two bars supported above, and more support rods are arranged on around supporting arc plate, and support rod 3 is in horizontal direction 25 degree of -45 degree angle is preferably in 30 degree of angles.Monolith supporting arc plate 2 is spliced by two pieces or muti-piece supporting arc plate, at two pieces Or two pieces or three pieces of hollow buffer bars, adjacent hollow are set between muti-piece supporting arc plate and on the supporting arc plate of approximately horizontal plane The spacing greater than slot thickness in channel steel is reserved between buffer bar.Or hollow buffer bar constitutes one with channel steel inside groove and combines Body reserves the spacing of certain distance between two neighboring association；It is possible to further only at the arc plate of level of approximation it is more Setting interval, that is, cannot be not provided with being spaced at the arc plate of level of approximation；It in other words, must at the arc plate of level of approximation A certain number of intervals must be set, but can be not provided with being spaced in arc board ends part.It is, in the approximate water of supporting arc plate Flat place cannot directly use monoblock type arc plate.It is strong lower than the shock resistance of split type arc plate using the impact strength of monoblock type arc plate Degree, and service life reduces.Rigid supporting rod can be used for support rod 3, it is preferable to use high-intensitive spring, has buffering at this time The spring of performance greatly extends the service life of equipment.

Supporting arc plate during the hollow rubber of filling resilient material is buffer bed is respectively positioned on the arc surface of common point, Angle relative to common point is 135 degree or 120 degree, generally can 60 degree -160 degree between change, preferably 90 degree - Change between 140 degree.

Channel steel inside groove 104 is fixed on supporting arc plate using bolt 105；Further, channel steel inside groove passes through welding side Formula is fixed on supporting arc plate；Further, channel steel inside groove and supporting arc plate integrated molding, in integrated molding, more It is easy the area filling quicksand formed between the hollow buffer bar 101C of innermost layer and channel steel inside groove 104, to improve making for equipment Use the service life.

Spacing d between adjacent channel steel inside groove is the radius of semicircle hollow buffer bar 1/5th to half.

The hollow rubber of the filling resilient material of the utility model is buffer bed compared with prior art, the utility model It is simple with structure, at low cost, wearability is good, frictional force is low.The hollow rubber of especially filling resilient material is buffer bed to adopt It is designed with arcuate structure, so that blanking position stress is more evenly, also ensures the smooth smoothness of conveyer belt operation.In addition, hollow Rubber structure design, can absorb material impact force to the maximum extent.
