Abstract
The utility model discloses an anti-silt device of a power head box body of a rotary drilling rig. The anti-silt device of the power head box body of the rotary drilling rig comprises an inner bonding sleeve and an upper bearing end cover, wherein the inner bonding sleeve is connected with a gearwheel fixing ring, a double lip framework oil seal is installed in the upper bearing end cover, and a hair felt ring is installed in an upper sealing gland and connected with the upper bearing end cover through a bolt. The anti-silt device of the power head box body of the rotary drilling rig applies to a power head of the rotary drilling rig, protects the double lip framework oil seal installed in the power head box body, and then sundries such as silt can be prevented from entering the power head box body, and sediment can be prevented from depositing inside the power head box body; driving effect of a gear is improved, service life of the gear is prolonged, quality of gear oil of the power head box body is guaranteed, maintenance and service frequency of the power head is reduced, and maintenance cost is saved for a user. The anti-silt device of the power head box body of the rotary drilling rig has the advantages of being reasonable in design, simple in structure, convenient to maintain, safe, reliable and the like.
Description
Technical field
The utility model relates to a kind of rotary digging drill power head casing, is specifically related to a kind of anti-silt device.
Background technique
At present, from every policy of country, the major construction projects during the countries " 12 " such as railway construction, highway construction, guarantee house, water conservancy, airport construction all continue to advance, and even strengthen dynamics of investment, and this has just pulled the demand of piling machinery.Wherein, rotary drilling rig is one of equipment of commonly using, and the unit head casing is one of Infrastructure of rotary drilling rig.
the rotary digging drill power head casing of prior art as shown in Figure 1, the silt that drilling rod is taken out of easily is deposited on internal key cover 8 and locates with the gap of upper sealing gland 3, under the turning effort of unit head, silt easily locates to enter the lip place of single lipstick frame oil sealing 9 along gearwheel retainer ring 7 and the gap of upper sealing gland 3, be full of silt between the gearwheel retainer ring 7 of rotation and single lipstick frame oil sealing 9, of long duration, dell is worn and torn at the position of easily the gearwheel retainer ring being installed single lipstick frame oil sealing 9, single lipstick frame oil sealing 9 does not herein have seal action, silt enters box house thus, about time through a year and a half, just deposited the foul of 60mm left and right in casing, gear oil is seriously polluted, and had a strong impact on gear-driven efficient.The user needs the regular casing of opening to clear up silt and change gear oil, and be easy to three outside framework oil seals are damaged this moment, the construction speed that has so not only affected the user also invisible increase user's maintenance cost.
The model utility content
The technical problems to be solved in the utility model is that the rotary drilling rig power box easily enters silt, and a kind of anti-silt device of rotary digging drill power head casing that prevents that silt from entering is provided.
The technical solution of the utility model realizes in the following manner: a kind of rotary digging drill power head casing is prevented the silt device, comprise internal key cover and top bearing cover, the internal key cover is connected with the gearwheel retainer ring, the Double-lip framework oil sealing is installed in top bearing cover, and the felt circle is arranged in sealing gland and all crosses bolt and is connected with top bearing cover.
Be filled with lubricating grease in labyrinth between described upper sealing gland and internal key cover.
This device is useful on the unit head of serial rotary drilling rig; protected the Double-lip framework oil sealing in casing; thereby avoid the foreign material such as silt to enter casing; avoid being deposited on box house; improve gear-driven effect and working life, ensured the quality of casing gear oil, reduced the care and maintenance frequency of unit head; for the user has saved maintenance cost, have the characteristics such as reasonable in design, simple in structure, easy to maintenance, safe and reliable.Compared with prior art, the utility model also has the following advantages: 1. improve the sealing of unit head casing, stoped the box house that enters of the booties such as silt, guaranteed the turbidity test of gear oil, transmission efficiency and the working life of having improved gear.2. reduce the maintenance frequency of user to the unit head casing, guaranteed user's construction period, the maintenance cost of having saved the user.
Description of drawings
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Embodiment
As shown in Figure 2, a kind of rotary digging drill power head casing is prevented the silt device, comprise internal key cover 8 and top bearing cover 1, internal key cover 8 is connected with gearwheel retainer ring 7, Double-lip framework oil sealing 2 is installed in top bearing cover 1, and felt circle 5 is arranged in sealing gland 3 and is connected with top bearing cover 1 by bolt.Described felt circle 5 is the felt circles that soaked kerosene.
Form in labyrinth seal and labyrinth between described upper sealing gland 3 and internal key cover 8 and be filled with lubricating grease.
At first the utility model is installed to Double-lip framework oil sealing 2 in top bearing cover 1, be connected and fixed by bolt and casing, then felt circle 5 is mounted in upper sealing gland 3, fixing by bolt and top bearing cover 1, the lubricating grease of smearing with upper sealing gland 3, at last internal key cover 8 is mounted on gearwheel retainer ring 7, by lubricating cup 4 injection lubricating grease 6 in the labyrinth between sealing gland 3 and internal key cover 8 upwards.Described labyrinth refers to the space between sealing gland 3 and internal key cover 8.The utility model has adopted triple seal to prevent silt, and the first sealing is felt circle 5, directly blocks entering of silt; To be upper sealing gland 3 overlap with internal key is full of the lubricating grease labyrinth seal between 8 for second sealing, effectively stops the inside infiltration of silt by tortuous obstacle; Three seals is the Double-lip framework oil sealing 2 in top bearing cover 1, has dust reduction capability, stops silt to enter box house as final barrier.
The utility model has improved the sealing of unit head casing, has stoped the box house that enters of the booties such as silt, has guaranteed the turbidity test of gear oil, has improved transmission efficiency and the working life of gear.Reduce the maintenance frequency of user to the unit head casing, guaranteed user's construction period, the maintenance cost of having saved the user.
