Description
Technical field
This utility model relates to thrust wheel configuring technical field, is specifically related to wheel body end face growth form thrust wheel.
Background technology
Thrust wheel is as the primary load bearing structure part of crawler belt rotary drilling rig, and especially in large-tonnage crawler belt rotary drilling rig, its design and workmanship direct relation the complete machine safety of rig.Crawler belt rotary drilling rig operating mode is complicated, part thrust wheel stress is only had under load operating mode or cantilever lifting operating mode some special hanging, therefore the arrangement of thrust wheel dredges, for middle part, the form that two ends are close, and in order to meet the weight that crawler belt rotary drilling rig is gradually increased, number and the structural parameters of thrust wheel increase accordingly, and thrust wheel is arranged on bottom track frame, formed and roll during walking and between creeper tread upper bottom surface, the many employings in little tonnage of its installation form are open, use enclosed construction in large-tonnage.In life, thrust wheel thinks highly of power for Zhi Chongji, and it rolls on track link rail or track guide plate.Therefore, crawler belt is clamped with it, prevent crawler belt horizontal sliding from derailing, and crawler belt lateral sliding on the ground is driven when turning to, thrust wheel works sometimes in muddy water, and bears bigger shock loading, but its wheel body length of present thrust wheel only has 220-235cm(to see in Fig. 3 to be indicated a), it is unreliable to seal, and wheel rim is the most wear-resisting, and resistance to rolling is bigger；This utility model growth wheel body end face is to 230-245cm (be shown in indicating b in Fig. 1), and crawler crane side cover is provided with sealing ring, is possible to prevent crawler belt to crush, causes leakage of oil.Sealing reliable, wheel rim is wear-resisting and resistance to rolling is little.
Utility model content
The purpose of this utility model is to provide wheel body end face growth form thrust wheel, and it increases wheel body end face, prevents crawler belt from crushing, cause leakage of oil.
In order to solve the problem existing for background technology, this utility model is by the following technical solutions: it includes side cover, floating seal, wheel body, axle, copper ferrum set, solid pin, growth wheel body end face；The both sides of described axle include side cover, and side cover is connected by solid pin and axle are fixing；Described axle be coated with iron and steel set；The outside of described iron and steel set is provided with wheel body；The two ends of described wheel body are provided with growth wheel body end face；On the installation axle of described iron and steel set, floating seal is installed.
The second O-ring seals and hexagonal spiro plug it is additionally provided with on described side cover.
It is provided with the first O-ring seals in described floating seal.
After using said structure, this utility model has the beneficial effect that it increases wheel body end face, prevents crawler belt from crushing, and causes leakage of oil, and has the advantages such as simple in construction, reasonable in design, cost of manufacture is low.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is further described.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with the drawings and the specific embodiments, this utility model is further elaborated.Should be appreciated that detailed description of the invention described herein, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1-2, this detailed description of the invention adopts the following technical scheme that it includes side cover 1, floating seal 3, wheel body 4, axle 5, copper ferrum set 6, solid pin 8, increases wheel body end face 10；The both sides of described axle 5 include side cover 1, and side cover 1 is connected by solid pin 8 is fixing with axle 5；The iron and steel that is coated with of described axle 5 overlaps 6；The outside of described iron and steel set 6 is provided with wheel body 4；The two ends of described wheel body 4 are provided with growth wheel body end face 10；On the installation axle of described iron and steel set 6, floating seal 3 is installed.
The second O-ring seals 7 and hexagonal spiro plug 9 it is additionally provided with on described side cover 1.
The first O-ring seals 2 it is provided with in described floating seal 3.
The first described O-ring seals is 93.3* 9.5 O-ring seals, and the second O-ring seals is 55* 3.1 O-ring seals.
The operation principle of this detailed description of the invention is: when assembling thrust wheel, before assembly, should be by each part close inspection respectively and cleaning up；Before axle sleeve assembles with axle, its cooperation face should be coated with a small amount of machine oil；Floating sealing ring should match assembling, and its sealing surface should coat lubricating oil；O must not have lubricating oil with the contact surface of floating sealing ring；O assembling can not distort.The side cover 1 of crawler belt is provided with sealing ring 3, and crawler belt is likely deviate from from thrust wheel during exercising, and is pressed onto side cover 1 and is provided with the position of sealing ring, causes leakage of oil；But increase wheel body end face 10, then crawler crane side cover 1 is provided with the position of sealing ring 3, by being possible to prevent crawler belt to crush, causes leakage of oil.
The above, only in order to the technical solution of the utility model to be described and unrestricted, other amendment or equivalent that the technical solution of the utility model is made by those of ordinary skill in the art, without departing from the spirit and scope of technical solutions of the utility model, all should contain in the middle of right of the present utility model.
