Abstract
The anti-deformation funnel for receiving and unloading ores comprises an ore receiving and unloading funnel. The anti-deformation funnel for receiving and unloading the ores is characterized in that a square box body is welded on the upper edge of a funnel plate of the ore receiving and unloading funnel, a rectangular box is welded on the middle portion of the funnel plate, the upper end surface of the square box body is leveled with the upper edge of the funnel plate, channel iron is arranged outside the square box body, a box body bottom board is arranged on the lower end of the square box body, the upper end surface of the channel iron and the upper edge of the funnel plate are welded together, and the bottom board of the box body and the bottom end surface of the channel iron are welded together. The anti-deformation funnel for receiving and unloading ores has the advantages that the square box body intensifies the rigidity of the upper edge of the funnel, the rectangular box intensifies the rigidity of the funnel plate, thereby improving the ability of resisting external deformation of the funnel, and thereby the anti-deformation funnel for receiving and unloading the ores not only prolongs the service life of the funnel, saves material cost and manual fee demanded for heavy repair, but also avoids huge indirect economic loss generated to enterprises due to shutdown when the funnel is in heavy repair.
Description
Technical field
The utility model belongs to the port traffic apparatus field, particularly relates to a kind of ore of unloading anti-deformation funnel.
Background technology
Ore in the known technology quarrel limit of unloading on the funnel is simple in structure, is welded by the steel plate and the funnel motherboard of 20 millimeters thick.In the funnel use, grab bucket is grasped material in cabin after,, the material in the grab bucket is discharged in the funnel by door machine rotating mechanism.The track of grab bucket loading campaign is a circular movement, must the funnel both sides on path of motion be impacted; Moreover when grab bucket was unloaded in funnel, because the flexibility of steel rope makes grab bucket that dancing be arranged, the both sides that also cause grabbing bucket to funnel impacted.Because the mechanical characteristics of funnel two stressed limits and part bucket body itself can not be resisted external impact force, if things go on like this go down and will outwards give prominence to, form the selenodont permanent deformation.Its consequence is to cause the funnel deformity limit to be ftractureed suddenly, and its machinery of unloading material is down caused unexpected injury.At present, the solution of reply the problems referred to above can only be regularly funnel to be carried out large repairs, change easily worn part, not only spend lot of manpower and material resources, and can't tackle the problem at its root, most critical be the funnel goods of can't unloading during the overhaul, caused tremendous loss to economic benefit of enterprises.
Summary of the invention
The utility model provides a kind of good rigidly, the ore of the unloading anti-deformation funnel of long service life for solving the technical matters that exists in the known technology.
The technical scheme that the utility model is taked for the technical matters that exists in the solution known technology is:
A kind of ore of unloading anti-deformation funnel comprises the ore funnel of unloading, and it is characterized in that: the unload funnel plate upper edge of funnel of ore is welded with square box, and the funnel plate middle part is welded with rectangle box.
The utility model can also adopt following technical scheme:
The upper surface of described square box is concordant with the funnel plate upper edge, and the outside of square box is a channel-section steel, and the square box lower end is a box bottom, the upper surface of channel-section steel and funnel plate upper edge weld together, box bottom and channel-section steel bottom face weld together.
The outside of described rectangle box is a steel plate, and both sides are the box side plate, the both sides of box side plate and funnel plate weld together, the upper edge of steel plate and box bottom weld together, the middle part channel-section steel weld together of the steel plate lower edge of box and funnel.
From Analysis of materials mechanics (σ max=M/W), the method that improves fine strain of millet rigidity has: (one) reduces maximal bending moment value (Mmax).That is to say that the maximal bending moment value not only is decided by the size of power, and be decided by the distribution of power on beam.The size of power is to be decided by need of work, and the reasonableness that power distributes on beam can reach by the reasonable Arrangement of bearing and load; (2) select reasonable sectional (W).Because module of anti-bending section is another key factor of control bending strength, its size is not only relevant with sectional area, and relevant with cross sectional shape.When cross sectional shape symmetry and neutral axis, adopt rectangle, i shaped cross section; When materials in tension and compression intensity is unequal, then require the asymmetric and neutral axis of cross section proterties.(3) increase constraint on the single supported beam.The length of single supported beam is just shortened in the constraint of increase and decrease bearing relatively, improves the rigidity of single supported beam, increases the ability of opposing external force deformation.
Advantage and the good effect that the utlity model has are: after the utility model has adopted above technical scheme, square box has strengthened the rigidity of funnel upper edge, rectangle box has strengthened the rigidity of funnel plate, improved the ability of funnel opposing dimensional deformation, not only prolonged the service life of funnel, required material expense, labour cost when having saved overhaul, and the huge indirect economic loss that enterprise caused is given in the shut-down when having avoided the funnel overhaul.
