Abstract
The utility model discloses a gear drilling machine crawler belt walking mechanism. The gear drilling machine crawler belt walking mechanism comprises two crawler belt walking units which are connected through a transverse shaft and a balancing beam. Each walking unit is composed of a crawler belt support and a crawler belt plate, wherein the crawler belt support is provided with a drive wheel, a thrust wheel, a guiding wheel, a riding wheel and a tensioning device, and the crawler belt plate is installed on the crawler belt support. Each crawler belt support is further provided with a hydraulic motor, wherein an output shaft of the hydraulic motor is provided with a speed reducer, and an output shaft of the speed reducer is connected with the corresponding drive wheel in a matched mode. The walking mechanism is simple in structure, high in transmission efficiency and convenient to assemble and maintain.
Description
Technical field
The utility model belongs to open cast mine rotary drill technical field of structures, specifically refers to a kind of rotary drill creeper undercarriage.
Background technology
At present, domestic open cast mine mostly is common track structure with the creeper undercarriage of rotary drill; two crawler travel cell formations that bag is drawn together Transverse axle and equalizing bar and connected by their, each walking unit is all, by being provided with drive wheel, sprocket wheel, track adjusting wheel, caterpillar wheel, support roller, tightening device etc., the crawler rack building is installed, and be arranged on crawler belt on each crawler belt installation component composition, described drive wheel is arranged on one end of crawler rack, and drive wheel is meshed with crawler belt inner side.Existing creeper undercarriage is by the main motor that the is positioned at rotary drill owner platform source that is used as power, drive the drive wheel on walking unit by main motor output shaft through two groups of tween drive spindles, three groups of driving chains, drive wheel running drives crawler belt operation, thereby realizes the driving to traveling gear.Three grades of chain gears that this type of drive need to be led to long-distance drive rig walking, not only complex structure, mechanical efficiency is low, and easily there is the fault of landing or chain rupture in driving chain, the installation, maintenance of the equipment of giving brings great inconvenience, exists the problem that fault rate is high, rig operating rate is low.
Summary of the invention
The purpose of this utility model will provide a kind of rotary drill creeper undercarriage exactly, this traveling gear simple in structure, driving efficiency is high, it is easy to maintenance to assemble.
For achieving the above object, rotary drill creeper undercarriage of the present invention comprises: two crawler travel cell formations that are connected with equalizer by transverse axis, described each walking unit is all made up of the caterpillar block that is provided with the crawler rack of drive wheel, caterpillar wheel, guide wheel, support roller, tightening device and be arranged on described crawler rack, its special character is, on described each crawler rack, be also provided with HM Hydraulic Motor, on described hydraulic motor output shaft, be provided with reductor, the output shaft of described reductor and described drive wheel are in mating connection.
Further, the output shaft of the output shaft of described HM Hydraulic Motor, reductor and the axle center of drive wheel coincide.HM Hydraulic Motor, reductor are connected by mode like this with drive wheel, and the utilization ratio of HM Hydraulic Motor output work is the highest.
Again further, described reductor is planetary reducer.Adopt after planetary reducer, the compact conformation of this creeper undercarriage, transmitting ratio is larger, and efficiency is higher.
Traveling gear of the present utility model is by carrying hydraulic drive motor, when work, only need drive HM Hydraulic Motor operation by hydraulic pipe by the Hydraulic Pump on rotary drill service platform by operation setting, HM Hydraulic Motor can drive reductor to drive drive wheel running, thereby drives whole traveling gear.The sprocket chain strip traveling gear of existing structure complexity is changed over fluid pressure type traveling gear by the utility model, simplified the structure of traveling gear, assemble easy to maintenance, failure rate is low, and improved driving efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of rotary drill creeper undercarriage of the present utility model.
Fig. 2 is A portion structure for amplifying schematic diagram in Fig. 1.
Fig. 3 be in Fig. 2 B-B to cross-sectional view.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, rotary drill creeper undercarriage of the present utility model is described in further details.
Rotary drill creeper undercarriage as depicted in figs. 1 and 2, comprise: two crawler travel unit 3 that are connected with equalizer 2 by transverse axis 1 form, each walking unit 3 is all by being provided with drive wheel 4, caterpillar wheel 5, guide wheel 6, support roller 7, the crawler rack 9 of tightening device 8 and the caterpillar block 10 being arranged on crawler rack 9 form, on each crawler rack 9, be provided with HM Hydraulic Motor 11, in HM Hydraulic Motor 11, be connected with planetary reducer 12, reductor 12 is in mating connection with drive wheel 4, as shown in Figure 3, the output shaft of HM Hydraulic Motor 11, the spindle axis of the output shaft of planetary reducer 12 and drive wheel 4 coincides.
It is propulsion source that traveling gear of the present utility model adopts HM Hydraulic Motor 11, drives whole traveling gear thereby drive drive wheel 4 to rotate by HM Hydraulic Motor 11.When work, only need in HM Hydraulic Motor, connect a hydraulic pipe, staff is the operation of the hydraulic pump drive HM Hydraulic Motor on rotary drill service platform by operation setting, can drive drive wheel running, thereby drive whole traveling gear.The equipment such as the service platform of rotary drill are arranged on this traveling gear transverse axis 1 and equalizer 2 tops.
