Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In order to enhance the understanding of the solution of the present utility model, the technical problems need to be elaborated in combination with the related technologies, and the specific contents are as follows:

belt conveyor 19 is a common mechanical conveying device for transporting various articles from one location to another. The conventional belt conveyor 19 is extremely prone to dust emission during the conveying process, affecting the environment. Therefore, the belt conveyor 19 is mostly arranged in the sealed gallery 18, so as to meet the environmental protection requirement. Furthermore, the gallery cornice also often provides a cornice 23 structure for rain-proof drainage.

With the progress of society, the transportation radius of resource development is longer and longer, and traditional transportation mode can not satisfy the current transportation actual condition, so the material transportation of long distance belt feeder is more and more common. However, referring to fig. 1 and 2, the protruding cornices 23 on both sides of the conveyor gallery 18 building occupy additional area, and if transported over long distances, the additional land requirements are costly in a comprehensive sense, greatly increasing construction costs.

Specifically, the conveyor 19 includes a horizontal conveyor, an inclined conveyor, a folding conveyor, a transition conveyor, and the like. With the progress of society, the transportation radius of resource development is longer and longer, and the transportation length is often 10Km to 30Km. The land characterization problem is accompanied by long-distance transportation construction: firstly, the expense of land is very short and tens of thousands per square meter, so that the construction cost is greatly increased; secondly, the red line of the land defined by the owner is usually defined by reporting in the related departments, and the red line cannot be changed at all and does not have negotiation room. Therefore, the long-distance belt conveyor has very long transportation distance, and the land-marking red line is often defined and cannot be changed, so that the land-marking cost is very high, and the one-time investment is huge.

It should be appreciated that, referring to fig. 1, the fully enclosed belt conveyor gallery 18 is a common engineering structure, the characteristic red line size of which is generally determined by the outer profile size of the superstructure. This outer profile includes a number of factors such as the size of the equipment of belt conveyor 19, the size of walkways 20 on both sides of conveyor 19, the size of the steel truss members, the size of purlin assemblies 21, the thickness of color plate 22, and the size of cornices 23.

Namely, the floor space of the gallery 18 is equal to (1) the equipment size of the belt conveyor, (2) the size of the pavement 20, (3) the size of the steel structure truss member, (4) the size of the purline, (5) the high size of the color plate wave and (6) the size of the cornice 23.

Wherein (1) and (2) have minimum requirements specified by the specification, equal to about a fixed value; (3) the span of the truss is changed according to the difference, and the span is fixed and is approximately equal to the numerical value; (4) the purline size reduction is based on the premise of increasing the engineering quantity, and has certain defects in the size reduction; (5) the thickness of the color steel plate 22 is mainly limited by the color plate model which is easy to purchase in the market; therefore (6) reduction becomes the preferred location for reducing the outer profile size of the fully enclosed belt conveyor gallery 18.

In particular, the thickness of the color steel plate 22 mainly refers to the wave height of the color steel plate 22, and is mainly limited by purchasing without problems under conventional weather conditions, but in areas with large wind load, the color steel plate model is selected by considering color plate calculation.

The cornice nodes of the double-slope roof of the totally-enclosed gallery 18 of the traditional belt conveyor 19 are shown in the following diagram set: the minimum value of the single-side cornice 23 is 200mm, the two sides reach 400mm, and the numerical value is larger.

Specifically, the scheme shortens the transverse frame until the to-be-sealed 14 is arranged between the transverse frame and the longitudinal frame, and seals the to-be-sealed 14 through the cornice sealing plate 1, so that the original 23-mouth nodes of the corridor overhanging eave are replaced, the outline projection size of the corridor 18 is reduced, the land-marking area is saved, the engineering cost is reduced, and the reasonable utilization of land resources is facilitated; in addition, this scheme is convenient to drain, is favorable to reducing the wind load of cornice moreover, reduces the emergence of wind and takes off the phenomenon, improves stability and the security of structure.
