Background technology
Excavate rock loader and be mainly used in the space-constrained hole and adopt operation, gather and carry the construction entrucking like the rubble earth material of various mines such as metallic ore, coal mine roadway and water power, tunnel engineering.It is to be engaged with conveyer by manipulator; Take off quarrel and carry the entrucking function to unite two into one; Adopting the process units of the all-hydraulic control system that electronic or diesel engine drives, have safety and environmental protection, energy consumption is little, efficient is high characteristics, is the requisite advanced person's of bargh winning equipment.Crawler type on the existing market is excavated the rock loader running gear and is generally adopted the steel ball plunger piston hydraulic motor or adopt cycloid hydraulic motor to advance, retreat and turn to through epicyclic reduction gear drive crawler belt; Have following point: (1) steel ball plunger piston hydraulic motor costs an arm and a leg; Volume is bigger, and flow rate of hydraulic system and pressure are had relatively high expectations; (2) because the crawler body installing space is less, epicyclic reduction gear volume and torque can't be satisfied equipment requirements; (3) for hole, small bore ore deposit, need design smaller and more exquisite excavation rock loader, because steel ball plunger piston hydraulic motor and epicyclic reduction gear are bulky, can't meet requirements.
The utility model content
It is lower that the purpose of the utility model provides a kind of cost, less demanding to hydraulic efficiency pressure system, and the moment of torsion of walking is big, and equipment occupation space is little, and crawler type easy to maintenance is excavated the rock loader travel driving unit.
For realizing above-mentioned purpose, the utility model adopts following technical scheme:
Crawler type is excavated the rock loader travel driving unit; Comprise running gear adapter plate, change speed gear box, HM Hydraulic Motor, drive sprocket; Said change speed gear box comprises driving gear, intermediate drive gear one, intermediate drive gear two, output drive gear; Said driving gear is installed on the input shaft of change speed gear box, and meshes with intermediate drive gear one, and intermediate drive gear two is installed on the same axle with intermediate drive gear one; And with output drive gear engagement, output drive gear is installed on the output shaft of change speed gear box; Said HM Hydraulic Motor is connected through the input shaft of female splines one and change speed gear box, and drive sprocket is connected through the output shaft of female splines two and change speed gear box; Said HM Hydraulic Motor adopts cycloid hydraulic motor.
For making output torque reach requirement, the change speed gear box speed ratio gets 6.25～9.51.
As preferably, the number of teeth of driving gear, intermediate drive gear one, intermediate drive gear two, output drive gear is respectively 14,35,14,35, perhaps is 14,39,14,39, perhaps is 12,37,12,37, perhaps is 13,36,13,36.
Because the utility model adopts cycloid hydraulic motor with low cost, and is less demanding to flow rate of hydraulic system and pressure during work, only needs during work to insert two road binders, so cost is lower, less demanding to hydraulic efficiency pressure system; The utility model is used the alternative epicyclic reduction gear of design-calculated change speed gear box voluntarily simultaneously, makes output torque big, and equipment occupation space is little, can satisfy the needs in hole, small bore ore deposit; In addition, the cycloid hydraulic motor and the change speed gear box of the utility model connect as one, and install, use and keep in repair all more convenient.
