The belt conveyor is the most important bulk material conveying and loading and unloading equipment, can be widely applied to the industrial fields of mines, metallurgy, building materials, chemical industry, electric power, food processing and the like, and can be widely applied to coal mines, metal mines, steel enterprises, ports, cement plants and the like. The belt conveyor can overcome various terrain limitations in long-distance transportation, and transportation cost can be greatly reduced. The conventional belt conveyor adopts a steel structure truss and concrete or a steel structure bent frame upright column structure at an overhead section, and the common span is 18m, 24m and 36 m. However, most of the conventional belt conveyor trusses are complete steel structure truss galleries, and the intermediate frames and carrier rollers of the belt conveyor are arranged on the trusses in a form that steel performance is not fully utilized, so that the steel consumption is large. And due to the maintenance requirement, an overhaul channel is required to be arranged in the corridor of the belt conveyor, and the use of extra steel is increased. Therefore, the gallery structure of the triangular truss belt conveyor with a small steel consumption and an access passage is necessary.

Furthermore, the belt conveyor also comprises an overhaul channel, wherein the overhaul channel mainly comprises a walkway plate and a cross beam overhanging out of the truss; one side of the maintenance passage, which is far away from the truss, is provided with a railing.

Furthermore, the cross braces are arranged at the two ends and the middle position of the truss.

Further, the side rods are connected with each other to form a triangle with the top rod or the bottom rod; the triangle is an isosceles triangle.

furthermore, the included angle between the side rods and the cross beam is 60-75 degrees.

Further, the adhesive tape machine comprises an upper adhesive tape machine and a lower adhesive tape machine; the upper belt gluing machine is arranged on an upper carrier roller beam fixed on the inner side wall of the upper layer of the truss, and the lower belt gluing machine is arranged on a lower carrier roller beam fixed on the inner side wall of the lower layer of the truss.

Furthermore, the truss also comprises a covering shed for covering the whole adhesive tape machine; the covering shed is arranged in the truss, and the side surface of the covering shed is an inclined surface.

Furthermore, a longitudinal secondary beam is arranged below the walkway plate; the secondary beams are connected to the bottoms of the cross beams in a staggered mode.

Furthermore, hinged supports are arranged at the bottoms of the two ends of the bottom rod.

The invention has the beneficial effects that:

(1) The cross beam at the bottom of the truss is cantilevered outwards to form an overhaul channel, so that the bottom structure of the truss is fully exerted, and meanwhile, the requirement of convenience in manual overhaul is met under the condition of small steel consumption;

(2) Compared with the prior art, the cross-brace arrangement at the bottom of the truss effectively reduces the steel consumption and enables the belt conveyor to have good stability integrally by matching with a triangular truss structure. Under the same working condition, the steel amount of the structure adopting the technical scheme is reduced by 13-15 percent compared with the steel amount of the conventional truss, and the investment per linear meter can be reduced by about 500 yuan;

(3) The setting of covering the canopy not only can reduce the dust excessive, and covers the canopy side and form the inclined plane, and the area of receiving the wind obviously reduces during the wind load effect for the structure receives the wind load and diminishes, and further supplementary reduction truss overall structure uses the steel volume, economy practices thrift.

Detailed Description

The invention is further described below with reference to the accompanying drawings.

Reference is made to the accompanying drawings. The invention comprises a triangular truss 1, an overhaul channel 2 and a belt conveyor which is arranged in the truss 1 up and down. The truss 1 comprises a longitudinal top rod 101, two bottom rods 201 arranged longitudinally in parallel, a plurality of end connecting rods 103 and a plurality of side rods 102. The head end of ejector pin 101 and the head end of sill bar 201 and the tail end of ejector pin 101 and the tail end of sill bar 201 all connect through end connecting rod 103 to make truss 1 terminal surface be triangle-shaped, wholly be the triangular prism. The side rods 102 are distributed on two sides of the truss 1, and two ends of the side rods are connected with the top rods 101 and the bottom rods 201 and connected with each other to form a triangular arrangement, so that the stability of the truss is effectively improved. Specifically, the side bar inclination angle is 60 °, and the design is in the form of an isosceles triangle.

the truss of this embodiment further includes a plurality of cross beams 205 with transversely arranged bottoms, which are perpendicular to the bottom rods 201 and have two ends respectively overhanging out of the truss body. A walkway plate 5 is laid over the overhanging portion of the cross beam 205 to form an access passage 2 on both sides of the girder 1. In particular, the cross beams 205 are preferably spaced 1.5m from each other. As a main stress structure of the access passage, the overhanging length of the cross beam 205 is preferably not more than 1 m. Of course, the access channels 2 on both sides may have different widths, but the difference is not preferably more than 15 cm. In particular, the included angle between the side bars 102 and the cross beam is 60-75 degrees.

In order to better increase the bearing capacity of the service aisle 2, a longitudinal secondary beam 204 is provided at the bottom of the corresponding beam portion, which secondary beam 204 coincides with the line of symmetry of the service aisle. An outer beam 202 is also connected longitudinally to the end of the cross beam 205, on which the balustrade 6 is arranged vertically.

Since the cross beams 205 and the bottom beams 201 of the bottom of the girder are criss-crossed with each other to form a plurality of square regions, in order to increase the stability of the girder 1, the cross braces 203 are horizontally disposed in the square regions located at both ends and in the middle.

In particular, the bottom rods 201, the cross beams 205, the cross braces 203, the outer beams 202 and the secondary beams 204 are made of H-shaped steel or i-shaped steel.

The tape machine includes an upper tape machine 403 and a lower tape machine 404. The upper belt gluing machine 403 is installed on an upper carrier roller beam 401 fixed on two inner side walls of the upper layer of the truss, and the lower belt gluing machine 402 is installed on a lower carrier roller beam 404 fixed on two inner side walls of the lower layer of the truss. The upper idler beams 403 and the lower idler beams 404 are arranged along the length direction of the truss 1. Particularly, the distance between the upper carrier roller beam and the lower carrier roller beam needs to meet the installation width of the belt conveyor, and L-shaped angle steel, C-shaped section steel and Z-shaped section steel can be selected as materials.

When the belt conveyor needs to be covered, a covering shed 7 for wrapping the upper and lower carrier rollers and the upper and lower adhesive tape machines can be arranged. The covering shed can be made of profiled steel plates or thin steel plates, and an inspection window made of daylighting plates is arranged every 5-10 m at intervals of the covering shed 7. The covering shed 7 is fixed on the side rods 102 in a mechanical connection mode, so that the covering shed is convenient to disassemble and overhaul. In particular, the two sides of the shelter 7 are inclined.

The bottom of the two ends of the bottom rod 201 are both provided with hinged supports 3. In the present embodiment, the bottom rod 201, the end link 103, the top rod 101, and the side rod 102 are made of steel pipes, but it is needless to say that the shape steel may be selected according to the actual situation.

The standard section truss spans 18m and can be increased to 24m on a 1.5m basis.

It should be noted that the above describes exemplifying embodiments of the invention. It will be understood by those skilled in the art, however, that the present invention is not limited to the embodiments described above, which are given by way of illustration of the principles of the present invention, but that various changes and modifications may be made without departing from the scope of the invention as defined by the appended claims.
