Description

Technical Field

[0001] The utility model relates to a cab of a tunnel boring machine, in particular to a fully enclosed cab of a tunnel boring machine. Background Art

[0002] The heat exchange capacity of the deep area of ​​the mine is weak. It is calculated that the ground temperature increases by about 4°C for every 100m decrease in the average mining depth, so the high temperature phenomenon in the deep mine is very obvious. In the mechanized excavation process of the mine, the mechanized excavation equipment that converts fossil energy into power has high self-heating capacity and low effective power coefficient. Most of the energy is discharged to the operating mine in the form of exhaust gas, causing the operating temperature of the deep mine to rise further. In particular, the roadheader, as a key equipment for the transformation of the mining mode from drilling and blasting to mechanical cutting, has been applied to mines to a certain extent because of its comprehensive functions such as mechanical cutting, collection, transportation, and dust removal. However, because the roadheader adopts a mechanical cutting and ore-dropping method, there are problems of high temperature and high dust during the operation.

[0003] The existing tunnel boring machine cabs are generally open structures, making it difficult to achieve air conditioning in the cab space. The cab operators are in a high temperature and high dust working environment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fully enclosed cab of a tunnel boring machine with an air-conditioning function. Firstly, the cab is formed into a closed space, and under the action of an external air-conditioning refrigeration system, the operator can be isolated from high temperature and high dust to ensure that the operator is in a clean and comfortable working environment; secondly, the impact resistance of the cab roof is further improved.

[0005] The technical solution of the utility model is as follows:

[0006] A fully enclosed cab of a tunnel boring machine with air conditioning function, comprising a cab frame and a ceiling fixedly installed on the upper side of the cab frame, the cab frame comprising a first column, a second column, a third column and a fourth column arranged longitudinally and parallel to each other, the ceiling, the left side wall where the second column and the third column are located, the right side wall where the first column and the fourth column are located, the front side wall where the first column and the second column are located, the rear side wall where the third column and the fourth column are located and the tunnel boring machine operating table form a closed space, a rear upper cross beam is connected between the upper end of the third column and the upper end of the fourth column, and a rear lower cross beam is connected between the lower end of the third column and the lower end of the fourth column; a rear side guard plate and tempered glass are installed between the third column and the fourth column; a wiper rear mounting hole is provided on the rear side guard plate; an air conditioning air inlet pipe hole and an air conditioning air outlet pipe hole are also provided on the rear side guard plate; a glass water pipe hole is provided on the rear lower cross beam.

[0007] Preferably, an upper left crossbeam is connected between the upper end of the second pillar and the upper end of the third pillar, and a lower left crossbeam is connected between the lower end of the second pillar and the lower end of the third pillar; the first door frame and the second door frame are connected between the upper left crossbeam and the lower left crossbeam, and a door frame is installed between the first door frame and the second door frame, and a door guard plate is installed on the inner side of the door frame; tempered glass is installed between the second door frame and the third pillar and between the first door frame and the second pillar; an upper right crossbeam is connected between the upper end of the first pillar and the upper end of the fourth pillar, and a lower right crossbeam is connected between the lower end of the first pillar and the lower end of the fourth pillar; a right side pillar located between the first pillar and the fourth pillar is connected between the upper right crossbeam and the lower right crossbeam; a right side guard plate and tempered glass are respectively installed between the first pillar and the right side pillar and between the right side pillar and the fourth pillar; a right wiper mounting hole is provided on the right side guard plate.

[0008] Further preferably, the ceiling includes a triangular left upright plate and a triangular right upright plate, and the triangular bases of the left upright plate and the right upright plate are respectively connected to the left upper crossbeam and the right upper crossbeam; the ceiling also includes a front inclined plate and a rear inclined plate respectively connected to the other two sides of the triangle of the left upright plate and the right upright plate; the front inclined plate and the rear inclined plate form an angle less than 145° with each other.

[0009] More preferably, lifting rings are installed on the upper sides of the front inclined plate and the rear inclined plate.

[0010] Preferably, a front upper cross beam is connected between the upper end of the first column and the upper end of the second column, and a front lower cross beam is connected between the lower end of the first column and the lower end of the second column; a front side guard plate and tempered glass are installed between the first column and the second column; a front wiper mounting hole is opened on the front side guard plate.

[0011] The positive effects of the utility model are as follows:

[0012] First, the utility model forms a fully enclosed driving space through the frame, guard plate and tempered glass, effectively isolating the operator in the driving room from the external working environment of the tunnel boring machine, achieving the purposes of heat insulation, sound insulation, heat preservation and waterproofing. The air in the driving room is adjusted to clean gas with moderate temperature through the air inlet and outlet holes of the air conditioner, effectively avoiding the pollution of the operating environment by external high temperature and dust.

[0013] Second, the roof adopts a triangular cross-section design, and the angle between the front and rear inclined plates is less than 145°. When heavy objects such as gravel from the tunnel roof fall onto the roof, they are more likely to slide down, and the vertical downward gravity can be effectively dispersed to the front and rear inclined plates, ensuring that the cab will not be seriously deformed.

[0014] Third, three lifting rings are installed on the upper surface of the ceiling. During the lifting and disassembly process of the fully enclosed cab, the center of gravity of the entire fully enclosed cab can be self-positioned during the lifting process, thereby ensuring quick and stable lifting of the cab.

[0015] Fourth, tempered glass is installed on the front, rear, left and right sides of the cab, which provides the operator with a wider field of vision, enables the operator to observe the situation around the tunnel boring machine more clearly, and makes driving operations safer.
