Abstract

The invention discloses a buffering wheeled bed comprising a bed body. The buffering wheeled bed is characterized in that a plurality of turning wheels are arranged on the bed body, and the buffering wheeled bed is formed by permutation and combination of the turning wheels; compared with the prior art, buffering strips arranged densely on a buffering bed are replaced by buffering turning wheels, and sliding resistance is converted into rolling resistance, so that vertical force condition and level force condition of a belt conveyor blanking point conveyor belt are optimized, shock strength of the buffering bed is greatly increased, wear rate of the conveyor belt and each part is reduced, service life is prolonged, and accordingly, working efficiency of the whole conveying system is improved.

Description

A kind of buffering wheel bed

Technical field

The present invention relates to a kind of buffering wheel bed, belong to material handling machinery.

Background technology

Before buffer bed use, the material feeding buffer portion of belt conveyer mainly adopts impact idler to cushion the impulsive force of material, and last 100 years decades has been used in continuity, because impact idler has in use exposed a large amount of fatal defectives, a lot of Engineering Design Company have successively designed different material buffer devices in the world for this reason, invented buffer bedly at last, obtained users' approval through improvement progressively.

Buffer bedly be mainly used in substituting impact idler.Existing buffer bed bed surface is made up of buffer bar, and the impulsive force of buffer bar when mainly using good high resiliency layer and fully effectively having absorbed material and fall, to the impact of load-transfer device, improved the vertical force-bearing situation of discharging point load-transfer device when greatly reducing the material whereabouts.But, because what take place between fixing buffer bar and the load-transfer device of motion is cliding friction, so existing buffer bed snubber slide bed (chute, slide unit) that is called again, " cunning " word, though said the existing buffer bed vertical force-bearing situation that improves the discharging point load-transfer device, changed the horizontal force-bearing situation of original discharging point load-transfer device also, become cliding friction by friction of rolling, and contact surface increases, and makes the suffered resistance of motion of this section load-transfer device at double even tenfold, hundred times increase.

Summary of the invention

The objective of the invention is to overcome the defective that prior art exists, provide a kind of and can make the vertical force-bearing situation of belt feeder discharging point load-transfer device and the buffering wheel bed that horizontal force-bearing situation is all optimized.

Technical scheme of the present invention is: a kind of buffering wheel bed, and it comprises a body, characteristics are, are provided with N runner at the bed body, are arranged to form the buffering wheel bed by N runner, N＞1.

The arrangement mode of runner on the bed body can have multiple mode, arranges etc. as isosceles triangle arrangement, in-line (groined type).In-line (groined type) arrangement comprises horizontal and vertical, vertically arrange, namely be similar to traditional vertical buffer bar structure, just vertically changed into the rotaring wheel structures of a plurality of independent arrangements by the high elastic rubber buffer bar of integral body, the runner that multiple row is vertically arranged constitutes complete buffer bed bottom land; Transversely arranged, refer to that a plurality of runners (with respect to belt direction of transfer) on the bed body all are transversely arranged distributions, the lateral cross section that a plurality of runners of each horizontally-arranged are formed all is a buffer bed bottom land shape, and many horizontal rows constitute complete buffer bed bottom land to the runner of arranging.

The present invention also improves to some extent in shape at bed body bottom land.Traditional buffer bed bottom land is the dovetail groove bottom structure, load-transfer device with at the bottom of the dovetail groove for not exclusively to contact, load-transfer device only contact with dual-side and the base of bottom land, is unsettled all the time and locate load-transfer device corresponding to the base angle of both sides at the bottom of the dovetail groove, the support discontinuity equalization that causes load-transfer device, serious wear.The present invention is slick and sly arc with bed body bottom land structural development, no matter what form a plurality of runner is arranged with at the bed body, the bottom land lateral cross section of its formation all is arc.

Runner of the present invention can adopt elastomeric material to make, as rubber, plastics etc., to strengthen buffer action.In addition, below the leg of buffer bed bed body, can also be provided with shock absorber, be used for alleviating belt that enormous impact power causes and buffer bed self is impaired, reduce the fragile rate of parts, prolong its service life.

Compared with the prior art, the present invention has been modified into the buffering runner with original buffer bed buffer bar of gathering that goes up, make sliding resistance convert rolling resistance to, original " snubber slide bed " become " buffering wheel bed ", vertical force-bearing situation and the horizontal force-bearing situation of belt feeder discharging point load-transfer device are all optimized, improved buffer bed impact strength greatly, reduced the abrasion factor of load-transfer device and each parts, prolong service life, and correspondingly improved the work efficiency of whole delivery system.

Below in conjunction with drawings and Examples the present invention is done at length and to explain.

Description of drawings

Fig. 1-a kind of structural representation of the present invention;

The A of Fig. 2-Fig. 1 is to view;

The B of Fig. 3-Fig. 1 is to view;

Fig. 4-another kind of structural representation of the present invention.

The explanation of accompanying drawing drawing:

1 body, 3 runners, 4 legs, 5 cushion rubbers, 6 vertical troffers.

The specific embodiment

Embodiment 1, with reference to figure 1, Fig. 2, Fig. 3, the structure of bed body 1 is with existing buffer bed basic identical, at bed body 1 a plurality of runners 3 that isosceles triangle is arranged that are are installed, for the ease of installing, fixing, several vertical troffers 6 can correspondingly be set on bed body 1 at interval, runner 3 is assembled in vertical troffer 6, as shown in Figure 1, two avris are designed to the binary runner, middle for a plurality of monomer runners are the isosceles triangle arrangement, the curved structure of lateral cross section shape of the buffer bed bottom land of formation is with reference to shown in Figure 3.

In order to strengthen the impact resistance of buffer bed body, below the leg 4 of bed body 1, be provided with shock absorber 5 again, such as cushion rubber or recoil spring etc.

Embodiment 2, and with reference to figure 4, the structure that this is routine and example 1 are basic identical, difference is, a plurality of runners 3 on the bed body 1 are in-line (groined type) to be arranged, and a plurality of runners that laterally reach vertical cross arrangement constitute buffer bed bottom land, and its bottom land shape of cross section also is slick and sly arcuate structure.

Claims
