Description

Technical Field

[0001] The present invention relates to the technical field of corridor steel structures, and in particular to a modular assembly and calibration device and method for an ultra-long conveying corridor steel structure. Background Art

[0002] In recent years, relying on the huge demand for raw materials such as cement due to infrastructure construction, cement and other industries have developed rapidly, gradually forming a cement industry cluster with Southern Cement as the core, with more than 10 million tons of cement clinker shipped out annually. Except for a small part of these products that are transported by rail, most of them are transported to the dock by heavy trucks and then transported by water. This mode of transportation not only seriously restricts the product transportation capacity and increases logistics costs, but also puts the local area under certain traffic pressure and environmental risks.

[0003] To solve this problem, super-long conveyor corridors came into being. The conveyor belts are high temperature resistant and fully sealed. After operation, the cement clinker produced by upstream member enterprises is transported to the transfer station through the belt machine corridor, and then transported to the wharf by the transfer station through the belt machine corridor, and then transported to various places by water from the wharf for distribution. This is also a new transportation mode of air-water transport after river-sea transport.

[0004] The ultra-long conveyor corridor transports cement clinker to the dock, which not only greatly reduces the traffic of large trucks on the road and relieves the pressure of road transportation, but also realizes the "zero emission" transportation of goods and reduces the impact of dust, noise and exhaust gas on the environment. "

[0005] The assembled corridor is a mining supporting equipment that can greatly shorten the project construction period and reduce construction costs. It is a belt conveyor corridor closure device that can be used in mining sand and gravel yards, metallurgy, coal and other industries to close bulk material transportation and reduce dust and noise pollution in the transportation process.

[0006] The assembled corridor is one step faster in construction. The assembled corridor adopts modular design and split processing. The whole is composed of corridor base frame, corridor upper frame, corridor side beam, lighting board, support position, reinforcement support and other parts. Different parts are transported to the project site for assembly, which can greatly shorten the project construction period and reduce construction costs. The assembled corridor is hoisted as a whole. The internal design has a fixed position for the cable tray. Before on-site hoisting, the top can be directly sealed and assembled, and hoisted as a whole. The assembled corridor is sealed and environmentally friendly. The patterned plate at the bottom of the corridor is cut by laser cutting. The entire ground is seamlessly connected, with good sealing, no dust leakage, and environmentally friendly production.

[0007] The components of the assembled corridor include corridor base frame, reinforcement support, corrugated side plate, bottom pattern plate, corridor side beam, lighting plate, corridor upper frame, support position, etc. The corridor is also equipped with fixed positions for cables, lighting devices and surveillance cameras.

[0008] The assembled corridor has high bearing capacity and structural strength, and is flexible and convenient to install. The combined connection is achieved by bolting the connecting plates on the vertical surface of the corridor. Compared with the traditional belt conveyor corridor, the construction period is short, the project volume can be closed, and the construction cost is reduced.

[0009] As disclosed in application number 202122047517.4, an assembled corridor comprises corridor A and corridor B, wherein corridor A comprises an upper support frame, two side beams and a lower support plate, wherein the upper support frame and the lower support plate are fixedly connected to the upper and lower edges of the side beams at both ends respectively by bolts, the upper surface of the upper support frame is provided with a color steel tile, the two ends of the side beam are respectively vertical inclined surfaces, and the inner and outer side walls of one end of the vertical surface of the side beam are welded with connecting plates, connecting holes are opened on the connecting plates, and a frame is fixedly connected to the edge of one end of the inclined surface of the side beam, and connecting holes are opened at the edges of the frame. The structures of the corridor A and corridor B are the same, and the connecting plates on the vertical surfaces of the corridor A and corridor B are fixedly connected by bolts. The utility model has the advantages of high bearing capacity and structural strength of the corridor, good production quality of the corridor, short construction period, low construction cost, flexible and convenient construction, etc.

[0010] However, most of the current corridors have problems such as difficulty in assembly at high altitude, poor assembly accuracy between modular boxes, difficulty in positioning, low assembly efficiency, low degree of assembly automation, high assembly labor intensity, and low degree of modularization of corridor boxes.

[0033] 4. By setting up a height adjustment mechanism, the core column can be effectively tightened after changing the height of the column. On the premise of ensuring that the column has a height adjustment function, the overall structural stability of the column is guaranteed.

[0034] 5. By setting a wedge-shaped height increaser, facing the overall assembly error, a wedge-shaped height increaser is set to adjust the height error generated during the assembly process of the corridor box, thereby reducing the high-precision requirements for the modular box and reducing the high-precision assembly manufacturing cost of the box.
