It increase accordingly, and when machine is in uneven Ground Operation, the impact force that guide wheel is subject to passes to mandril, and mandril generates upward
Power is scratched, when scratching intensity of the power greater than mandril, mandril can generate bending deformation, and then other components of tensioning apparatus is caused to damage
It is bad, it causes walking mechanism to fail and is not easily repaired, Yi Yinqi disorderly closedown, and influence operating efficiency.
Utility model content
Against the above deficiency, the utility model provides a kind of protection mechanism of anti-stop-band mandril track takeup damage.
The utility model reaches above-mentioned purpose by following scheme:
A kind of protection mechanism of anti-stop-band mandril track takeup damage, including pedestal, rolling wheel support, idler wheel and axis
Pin, the rolling wheel support are mounted on the base, and the idler wheel is mounted on rolling wheel support by pivot pin, the track takeup
Mandril be arranged inside rolling wheel support and under idler wheel, on the mandril of the idler wheel bottom surface and track takeup top surface have
There is the gap of 0.8mm-2mm.
Preferably, the rolling wheel support is the rectangular support frame of interior sky.
It is further preferred that the spacing inside the rolling wheel support is greater than mandril outer diameter.
Preferably, gap of the top surface with 1mm on the mandril of the idler wheel bottom surface and track takeup.
Preferably, the rolling wheel support is bolted on pedestal.
Preferably, the top of rolling wheel support is arranged in the idler wheel.
It is further preferred that the 8mm-10mm of its outer diameter top surface on rolling wheel support is arranged in the idler wheel.
Preferably, piston nose face and the guiding wheel shaft of track takeup of track takeup is arranged in the pedestal
The middle position of the distance of the heart.
The protection mechanism of the utility model can be used for the damage of anti-stop-band mandril track takeup, such as SB13 type pushes away
A tensioning with mandril type that the walking mechanism of rake machine uses is set.
Above-mentioned protection structure is used in the track takeup with mandril, for preventing track takeup from damaging,
Pedestal is fixed on vehicle frame platform, such as is fixed by welding manner, by piston nose face at a distance from guide wheel axle center
The protection mechanism of a roll wheel assembly formula is arranged in middle position, and idler wheel is fixed on the top of tensioning mandril, rolls in level walking
The gap of wheel and mandril makes idler wheel not to be pressed onto mandril so that protection mechanism will not influence mandril and the tensioning to mandril
The operation set is opened, and tensioning apparatus buffers backward when guide wheel is hit, the upper surface of mandril and idler wheel form rolling friction, make
Tensioning apparatus remains at axially loaded, minimizes and scratches power, to improve the use longevity of tensioning device structure
Life, enhances the reliability of walking mechanism.
The protection mechanism of the utility model strengthens the structural strength with mandril tensioning apparatus, after effectively eliminating track wear
The tensioning apparatus failure of generation, prevents walking mechanism from damaging, and structure is simple, reliable and practical.
Detailed description of the invention
Fig. 1 installs and uses structure for the protection mechanism that the anti-stop-band mandril track takeup of specific embodiment damages and shows
It is intended to.
Fig. 2 is the A-A cross-sectional structure schematic diagram of the protection mechanism in Fig. 1.
Wherein, 1- tensioning spring assembly, 2- piston, 3- tensioning hydro-cylinder, 4- mandril, 5- soldering member, 6- guide wheel, 7- guidance
Wheel support, 8- pedestal, 9- rolling wheel support, 10- pivot pin, 11- idler wheel, 12 pouring orifices.
Specific embodiment
The utility model is further described below in conjunction with specific embodiment.
Structure chart is installed and used for protection mechanism as shown in Figure 1, protection structure is as depicted in figs. 1 and 2, including pedestal 8, bottom
Seat 8 is welded on vehicle frame platform, is welded on the front end face to the middle position of this section of distance in 6 axle center of guide wheel of piston 2,
Rolling wheel support 9 is the rectangular support frame of interior sky, and rolling wheel support 9 is fixed by bolts on pedestal 8 and mandril 4 is arranged in idler wheel branch
The inside of frame 9, idler wheel 11 are mounted on rolling wheel support 9 by the connection of pivot pin 10, the bottom surface of idler wheel 11 and the upper top surface of mandril 4
There is the gap of 1mm, to guarantee that idler wheel is not pressed onto mandril and in mandril by mandril when above scratching power and idler wheel shape in level walking
At rolling friction, tensioning apparatus is made to remain at axially loaded, minimizes and scratch power.
It is arranged on the vehicle frame platform of walking mechanism in Fig. 1 with mandril track takeup, piston 2 is mounted on tensioning oil
In cylinder 3, mandril 4 is bolted in tensioning hydro-cylinder 3, and mandril 4 is bolted to soldering member 5, and soldering member 5 is solid by bolt
It is scheduled on guidance wheel support 7, guidance wheel support 7 is fixed on the axis of guide wheel 6 with positioning pin.
The installation process of protection mechanism in Fig. 1 is as follows: the distance of 2 front end face of piston determining first to 6 axle center of guide wheel
Middle position, making idler wheel 11, its middle line installs idler wheel in pedestal 8 is welded and fixed in this position, behind setting position after fixation
Component adjusts the height of rolling wheel support 9, so that the upper top surface of its bottom surface and mandril 4 is had the gap of 1mm, guarantees in level walking
When idler wheel be not pressed onto mandril.
The protection mechanism course of work in Fig. 1 is as follows: 2 rear portion of piston resists tensioning spring assembly 1, and lubricant grease passes through note
Hydraulic fluid port 12 injects tensioning hydro-cylinder 3, and oil cylinder is pushed to move outward, pushes and moves outside guide wheel 6, makes crawler tensioning.Machine is on not level land
Guide wheel 6 is impacted when face is advanced, and impact force is transmitted to the other component being attached thereto, until tensioning spring assembly is arrived,
It is buffered by tensioning spring and receives its impact force, impact force disappearance post-tensioning device state back to normal, during this, due to top
Bar is in an intermediate position, and power is scratched in generation, and deform damage.By installing mechanism, top caused by scratching power is prevented in time
Bar deformation, makes entire tensioning apparatus be maintained at axial movement, idler wheel can reduce the friction of mandril.
The above, the only preferable specific embodiment of the utility model, but the protection scope of the utility model is not
It is confined to this, anyone skilled in the art is within the technical scope disclosed by the utility model, practical according to this
Novel technical solution and its design is subject to equivalent substitution or change, should all cover within the protection scope of the present utility model.
