Description

Belt type roasting machine track

Technical Field

The utility model relates to a metal smelting field, concretely relates to belt roasting machine track.

Background

The belt type roasting machine is the core process equipment of a belt type oxidation pellet production line and is used for drying, preheating, roasting, soaking and cooling pellet raw materials to finally produce finished pellet ore meeting the process requirements. The roasting machine skeleton consists of a head skeleton, a middle skeleton and a tail skeleton, and is a main structure frame for bearing all the parts of the roasting machine. Contain track and bend that the platform truck moved in the skeleton: the track is divided into an upper track and a lower track; the curve is divided into a head curve and a tail curve. The trolley runs on a closed horizontal track and on the head and tail curve. When the trolley is in a curve, due to the action of centrifugal force, the pressure on the side face of the track is large, and the bolts are subjected to shearing force under the conventional bolt connection condition, so that the bolts are easy to break, and accidents are caused.

Disclosure of Invention

An object of the utility model is to provide a stable in structure, long service life's belt roasting machine track.

In order to achieve the above purpose, the utility model adopts the technical proposal that:

a track of a belt type roasting machine comprises a track framework, a pair of upper tracks and a pair of lower tracks, wherein the pair of upper tracks and the pair of lower tracks are arranged on the track framework, the track framework comprises a pair of stand columns, cross beams are connected between the stand columns, the upper tracks are arranged on the top surfaces of the upper cross beams through track supports, the lower tracks are supported by a pair of cantilever beams, the track supports comprise frame bodies with I-shaped cross sections, the bottoms of the frame bodies are fixedly connected with the upper cross beams through screws, connecting plates are welded on the side surfaces of the frame bodies, and the connecting plates are fixedly connected with mounting seats on the; the upper track is arranged at the top of the frame body, the side face of the track is connected with the top face of the frame body in a welded mode through a connecting block, the two sides of the connecting block are respectively welded with a stop dog, and the stop dogs are fixedly welded with the frame body and the connecting block.

Further, the mount pad welds in two parallel diaphragms and with the vertical mounting panel of two diaphragm tip weldings of stand.

Furthermore, an upper cross beam and a lower cross beam are installed between the columns, and rib plates are welded at the joints of the upper cross beam and the lower cross beam and the columns.

Furthermore, diagonal brace rods are welded between the rib plates at the top of the lower cross beam and the upper cross beam.

Furthermore, the upright columns, the upper cross beams and the lower cross beams are H-shaped steel.

And furthermore, a column base bottom plate is welded at the bottom of the upright column and is fixed with the ground through screws.

After taking above technical scheme, the beneficial effects of the utility model are that: utilize the connecting block with track and leg joint, through dog fixed connection piece, this structural connection is firm, can effectively resist the centrifugal force of platform truck when the fixed track to orbital impact, prevents orbital not hard up and deformation, avoids the occurence of failure, effectively prolongs orbital life-span.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings:

as shown in fig. 1, a belt type roasting machine track is composed of a track frame 1, and a pair of upper tracks 2 and a pair of lower tracks 3 mounted on the track frame 1. The rail framework 1 is provided with a plurality of pairs of upright posts 4, an upper cross beam 5 and a lower cross beam 6 are welded between each pair of upright posts 4 in parallel, and the upright posts 4, the upper cross beam 5 and the lower cross beam 6 are all H-shaped steel, so that the strength of the upright posts is ensured. Ribbed plates 7 are welded at the joints of the upper and

lower beams

5,6 and the upright post 4. Diagonal braces 8 are respectively welded between the pair of rib plates at the top of the lower cross beam 6 and the upper cross beam 5, so that the structure of the track skeleton 1 is reinforced. The bottom welding of stand 4 has column base bottom plate 9, and column base bottom plate 9 passes through screw and ground fixed connection and fixes the track skeleton on ground.

The upper rail 2 is mounted on the top surface of the upper cross beam 5 through a rail support 10, the rail support 10 is a frame body with an I-shaped section, the bottom of the frame body is fixedly connected with the upper cross beam 5 through screws, and a connecting plate 11 is welded on the side surface of the frame body. The side of stand welding installation has mount pad 12, and the mount pad comprises two parallel diaphragm 13 that weld in stand 4 and with two diaphragm 13 tip welded vertical mounting panel 14, passes through bolt fixed connection between the connecting plate 11 of support body and the mounting panel 14, further supports the support body. The lower track 3 is supported by a pair of cantilever beams 15 welded to the columns, and the lower track 3 is installed through the same frame body and installation seat as the upper track.

Upper and

lower track

2,3 are installed at the top that corresponds the support body, use a pair of connecting block 16 with orbital side and the top surface welded connection who corresponds the support body, and the orbital both sides of connecting block 16 side are fixed track and support body, can prevent orbital lateral shifting, can provide the support to the impact of side direction. The two sides of the connecting block 16 are respectively welded with a stop block 17, and the stop blocks 17 are fixedly welded with the frame body and the connecting block to further strengthen the connecting block. Compared with the threaded connection, the structure is more stable and easy to process.
