Abstract
The utility model discloses a backhoe loader for flat inclined roadway tunneling. The backhoe loader comprises a loading transport trough (2), a gantry (4) and a chassis support (5). An included angle of the loading transport trough (2) and the horizontal plane is 17-18 degrees, a sector-shaped ballast accumulating plate push plate (3) is positioned on a ballast opening of the loading transport trough (2), an extending part (6) is positioned at the upper end of a scraping plate material-blocking plate positioned on the loading transport trough (2) and inclines for 25 degrees towards the inner side of the scraping plate material-blocking plate, and the gantry (4) and the chassis support (5) are of an integrated structure. The backhoe loader is used on an inclined roadway of 25 degrees, and ballast discharging efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of loader-digger for road, flat inclined gallery (≤25 °) driving, belongs to engineering machinery field.
Background technology
At present, in the mine, underground roadways such as water conservancy, water power, colliery are that road, the flat inclined gallery of light section (≤25 °) intersects combination mostly, still, the loader-digger product that uses in market can only be applicable to road, the little inclined gallery driving muck removal below 18 °.If then there is following problem in road, the inclined gallery driving muck removal that will be applicable to 18 °～25 °:
Walking driving force deficiency on the inclined gallery: usually, loader-digger adopts the chassis walking type of drive with the common shovel crawler of tonnage, and loader-digger is borrowed the power climbing by its horn more then.But, because loader-digger is subjected to the limitation of lane space, not disposing central slew gear, can't turn round, so can't creep by the digger arm power of borrowing, can only rely on the torsion of running motor to be implemented in climbing in the tunnel.
Loading material loading deficiency: the angle of plain edition loader-digger conveying trough and level ground is 24 °～27 °, when using in road, 25 ° of inclined gallery, the angle of conveying trough and level ground＞45 °, and the angle of repose of irregular quarrel material is 45 °, this structure can be in transmitting quarrel material process, has the serious material phenomenon of rolling, and only depends on scraper plate to force to transmit the quarrel material of fine granularity, have a strong impact on muck removal efficient, and have potential safety hazard.
The design irrationality of complete machine structure, digging mechanism connects with the loading conveying trough, when operation, the shock loading of excavating is transferred to conveying trough, simultaneously, lifts the groove oil cylinder and also has the tension and compression shock loading, can cause like this to carry stably to be cut material and to roll material, also can influence muck removal efficient.
Take the quarrel material and advance quarrel distance deficiency: existing loader-digger is when operation, the employing bucket is jettisoninged conveying trough scraper plate driving-chain to the excavation of quarrel material to quarrel mouth position by the buffering of hydraulic cylinder on, this function is not only to the designing requirement height of hydraulic cylinder, and the damage phenomenon to hydraulic cylinder is also relatively more serious, and has improved the maintenance cost of equipment.
Summary of the invention
The technical problems to be solved in the utility model is: a kind of loader-digger for road, flat inclined gallery driving is provided, satisfies the walking climbing capacity in road, the flat inclined gallery of light section (≤25 °), improve muck removal efficient and the effect of advancing to be cut.
The technical solution of the utility model is: a kind of loader-digger for road, flat inclined gallery driving, comprise and load conveying trough, door frame and chassis overhang, loading conveying trough and horizontal plane angle is 17 °～18 °, the quarrel mouth that loads conveying trough has fan-shaped long-pending slag plate push pedal, scraper plate on the loading conveying trough blocks the flitch upper end and is the extension, and 25 ° of the inboard inclinations of flitch are blocked to scraper plate in the extension; Door frame and chassis overhang are monolithic construction.
Reduce to load the angle between conveying trough and level ground, design load is at 17 °～18 °, when then complete machine uses in road, 25 ° of inclined gallery, angle between conveying trough and level ground≤43 °, namely satisfied in 45 ° of irregular quarrel material rolling angles of repose, simultaneously, change the blade structure of scraper chain driving-chain: increase scraper plate and block flitch, one extension is namely arranged above it, and tilt 25 ° the rollover phenomenon of the material of can avoiding like this being cut and guarantee to carry quarrel material stability and improve muck removal efficient increasing extension side direction in the conveying trough scraper plate.
Load conveying trough quarrel mouth and no longer adopt former nothing to amass slag plate push pedal structure, and adopt fan-shaped long-pending slag plate push pedal structure, there is oil cylinder in the long-pending slag plate push pedal outside, can promote fan-shaped long-pending slag plate push pedal and do the fan out action.So both guaranteed the stability of complete machine on 25 ° of slopes, and also be conducive to improve and excavate that quarrel is expected the long-pending quarrel effect of quarrel mouthful and to the clear end on ground, tunnel.
Adopt digger arm door frame and chassis overhang monolithic construction, the loading conveying trough does not bear and excavates the steadily transmission in conveying trough of shock loading influence quarrel material, and protection is simultaneously lifted the groove oil cylinder and not impacted by frequent tension and compression, prolongs its application life.
Select for use than the track drive motor with the common excavator track drive of tonnage motor torsional moment value big 40%, satisfy complete machine and creep on 25 ° of slopes, if satisfy this operating mode, can satisfy in the tunnel below 25 ° and creep.
Digging mechanism adopt horn to take off material to surpass driven pulley big apart from batch turning, and do not adopt the hydraulic cylinder mode of jettisoninging that relies on, both improved and excavated quarrel material efficiency of loading, application life of having improved hydraulic cylinder simultaneously, and reduce maintenance cost.
By above technical solution, can realize that loader-digger is in the function of road, the flat inclined gallery of light section (≤25 °) driving muck removal.
The angle of the utility model by reducing to load conveying trough and level ground, structure that scraper plate is carried in change, change modes such as excavating the quarrel distance after, use 25 ° inclined gallery, improved muck removal efficient greatly.If use in the gallery road, its efficiency of loading is higher.

The specific embodiment
To shown in Figure 7, a kind of loader-digger for road, flat inclined gallery driving comprises horn 1, loads conveying trough 2, door frame 4 and chassis overhang 5 as Fig. 1, and tonnage is 8 tons, and its track drive motor torsional moment value is with the common excavator CD-ROM drive motor of tonnage torque value 140%.Loading conveying trough 2 is 17 ° with horizontal plane angle, the quarrel mouth that loads conveying trough 2 has fan-shaped long-pending slag plate push pedal 3, scraper plate on the loading conveying trough 2 blocks the flitch upper end and is extension 6, and 25 ° of the inboard inclinations of flitch are blocked to scraper plate in extension 6, and door frame 4 and chassis overhang 5 are monolithic construction.Horn 1 is taken off when material, carries out greatly apart from batch turning surpassing the driven pulley position, does not adopt to rely on the hydraulic cylinder mode of jettisoninging, and both improved and excavated quarrel material efficiency of loading, the application life of having improved hydraulic cylinder simultaneously, and reduce maintenance cost.
