Description
Technical field
The present invention relates to coal mine roadway with the split-type 4 wheel driven walking mechanism of a kind of development machine in the road heading machinery field, be specially a kind of four-wheel drive, walker can realized and split, be beneficial to the Crawler Track Walking Device in Roadheader of underground transportation.
Background technology
What tunnelling machine generally adopted at present is crawler type walking mechanism, and the type of drive of this walking mechanism is rear wheel drive normally, and front-wheel only plays the effect of crawler belt being carried out tensioning and guiding as the regulating wheel of walking mechanism.The walking mechanism of this rear wheel drive drives whole development machine and realizes advancing, retreating and left-right rotation, but its climbing capacity is generally about 0～18 °.When the driving face gradient of down-hole reaches heavy grade more than 20 °, because the restriction of tractive force, contact area and the friction factor on crawler belt and ground are little simultaneously, and development machine can't be climbed, thereby cause development machine on the heavy grade work plane, can't use, can only adopt the mode of traditional big gun pick.Simultaneously in the underground transportation process, when particularly utilizing shaft transport development machine equipment, because digger traveling mechanism is overall structure, oversize in the longitudinal direction, bring inconvenience to underground transportation, more limited the use of large model development machine, some coal mining enterprises even because can't abandon using to underground transportation machinery driving.Therefore, develop a kind of development machine is new problem anxious to be resolved with split-type 4 wheel driven walking mechanism always.
Summary of the invention
The object of the present invention is to provide a kind of development machine split-type 4 wheel driven walking mechanism, its walker can decompose, be split as former and later two walkers, the front and back driving wheel is all installed drive unit realize four-wheel drive, and in rear walker installation tensioner, make rear drive sprocket have tensioning function, can regulate the degree of tightness of crawler belt.This walking mechanism is beneficial to underground transportation, thereby reduces cost of transportation, satisfies the use at the heavy grade work plane, strengthens walking mechanism tractive force, increases the working range of development machine.For the heavy grade working condition, the structure that block rubber is installed on the creeper tread is adopted in the design of crawler belt, contact area and the friction factor on increase and ground guarantee that crawler belt is non-slip when heavy grade is walked.
The object of the present invention is achieved like this: a kind of development machine split-type 4 wheel driven walking mechanism, by driving wheel, front walker, rear walker, drive unit, bolt, tensioning hydro-cylinder, tensioning frame, creeper tread, block rubber forms, the front and back driving wheel of digger traveling mechanism is bolted the installation drive unit, walker is designed to Split type structure, front walker and rear walker are bolted, tensioning hydro-cylinder is placed in the rear walker, tensioning frame is from the rear side rear walker of packing into, drive unit is fixed by bolts on the tensioning frame, and creeper tread and block rubber connect to form crawler belt with bolt; Operating principle and the method for operating of described device are: the front and back driving wheel of walking mechanism is installed drive unit, realizes four-wheel drive; Detachable walker structure is convenient to underground transportation; In rear walker, arrange tensioning apparatus, realize the tensioning to rear drive sprocket; Crawler belt is connected to form with bolt by creeper tread and block rubber, more be suitable for walking at the heavy grade work plane, driving wheel rotated before and after drive unit drove simultaneously when walking, make walking mechanism realize four-wheel drive, strengthen the tractive force of walking mechanism, more be conducive to climbing, simultaneously original non-detachable walker is divided into former and later two parts, significantly reduced the size of non-disconnectable inloading part, so that the underground transportation of walking mechanism is convenient, when tensioning hydro-cylinder is done stretching motion, promote tensioning frame flexible, adjust the degree of tightness of crawler belt, effectively increase contact area and friction factor with ground.
Main points of the present invention are its structure and operating principle.Its operating principle and method of operating are: the front and back driving wheel of walking mechanism is installed drive unit, realizes four-wheel drive; Detachable walker structure is convenient to underground transportation; In rear walker, arrange tensioning apparatus, realize the tensioning to rear drive sprocket; Crawler belt is connected to form with bolt by creeper tread and block rubber, more be suitable for walking at the heavy grade work plane, driving wheel rotated before and after drive unit drove simultaneously when walking, make walking mechanism realize four-wheel drive, strengthen the tractive force of walking mechanism, more be conducive to climbing, simultaneously original non-detachable walker is divided into former and later two parts, significantly reduced the size of non-disconnectable inloading part, so that the underground transportation of walking mechanism is convenient, when tensioning hydro-cylinder is done stretching motion, promote tensioning frame flexible, adjust the degree of tightness of crawler belt, effectively increase contact area and friction factor with ground.
A kind of development machine with split-type 4 wheel driven walking mechanism compared with prior art, having walker can decompose, be split as former and later two walkers, the front and back driving wheel is all installed drive unit, realize four-wheel drive, installation tensioner in rear walker, make rear drive sprocket have tensioning function, can regulate the degree of tightness of crawler belt, this walking mechanism is beneficial to underground transportation, reduces cost of transportation, satisfy the use at the heavy grade work plane, strengthen walking mechanism tractive force, increase the working range of development machine, for the heavy grade working condition, the structure that block rubber is installed on the creeper tread is adopted in design to crawler belt, increase contact area and friction factor with ground, guarantee when heavy grade walk the advantages such as crawler belt is non-slip, will be widely used in the coal mine roadway usefulness road heading machinery field.
