Description
Technical field
This utility model relates to crawler unit field.
Background technology
Known, crawler unit mainly includes bogie frame (track frame), drive sprocket, guide wheel, crawler belt, thrust wheel
With torr sprocket wheel, crawler belt is stretched between each wheel by chain rail, drive sprocket drive walking, and thrust wheel is arranged on the end of bogie frame
Portion, be used for transmit machinery weight to crawler belt, in the process of moving, it except along crawler belt chain rail roll in addition to, also want clamping chain
Rail, does not allow it laterally skid off, and when turning to, it forces crawler belt to slide laterally on the ground again, and thrust wheel is by its two ends
Chain rail is limited by flange, but the height of flange relatively low (diameter is little), it is easily caused derailing, in order to prevent derailed crawler belt,
Needing installation on the bogie frame at thrust wheel to protect chain mechanism and carry out spacing to crawler belt, the existing chain mechanism that protects mainly includes parallel
Two relative mounting rails and be connected to parallel two relative backplates between two mounting rails, two backplates are positioned at thrust wheel two ends, Zhi Chong
Wheel is between two mounting rails, owing to the restriction of crawler belt causes the limited height of backplate, and when chain rail jumps onto the flange of thrust wheel,
Then easily jumping over backplate further and derail, the most existing backplate is the platy structure of casting, and backplate can be often
Contact with chain rail, thus cause backplate to wear and tear, the most i.e. cause backplate to damage, reduce the service life of backplate.
Utility model content
The purpose of this utility model is for the deficiencies in the prior art, it is provided that one can effectively prevent the disengaging of caterpillar chain rail
Roller protect chain mechanism and crawler unit.
The purpose of this utility model realizes by following technical solution:
One protects chain mechanism, is used for preventing caterpillar chain rail from departing from thrust wheel, it is characterised in that: include being spaced and be mounted opposite
Two backplates outside thrust wheel two end flanges, caterpillar chain rail is limited in be supported by thrust wheel between two backplates, two backplates
Opposite face be respectively arranged with two baffle plates being positioned at thrust wheel flange both sides, the upper end of baffle plate higher than thrust wheel flange top with
Stop that caterpillar chain rail jumps onto thrust wheel flange.
Further, this utility model also includes two mounting rails that parallel interval is relative, and described in two, backplate is connected to
Between two mounting rails, backplate described in two is installed to, outside thrust wheel two end flanges, make thrust wheel be positioned at two peaces by two mounting rails
Between dress beam.
Further, the lower end of baffle plate described in two all extends downward and is connected with mounting rail described in two.
Further, the back of backplate described in two is respectively arranged with the two reinforcement gussets relative with its baffle plate described in two,
Described in two reinforcement gussets and two, the lower end of baffle plate all extends downward and is connected with mounting rail described in two.
Further, baffle plate described in the two of described backplate all tilts to extend, and make described in two spacing between baffle plate under
Supreme it is gradually reduced.
Further, described baffle plate is perpendicular to described backplate layout.
Further, the side epimere of the most described backplate of described baffle plate is formed for guiding caterpillar chain rail accurately to be propped up
The lead-in chamfered of roller supporting.
Further, described baffle plate and described backplate one forging molding.
Further, the side of the most described backplate of described baffle plate is between flange inner and outer, and close inner side.
A kind of crawler unit, the thrust wheel including track frame, being arranged on track frame and being arranged on track frame
Described protect chain mechanism.
This utility model has the advantages that
The opposite face of two backplates is respectively arranged with two baffle plates being positioned at thrust wheel flange both sides, and the upper end of baffle plate is higher than Zhi Chong
The top of wheel flange, thus can stop that caterpillar chain rail jumps onto thrust wheel flange, causes jumping over further backplate and takes off
Rail；The lower end of two baffle plates all extends downward and is connected with two mounting rails, uses solder bond, so may be used between baffle plate and mounting rail
Increase the bonding strength of backplate and mounting rail, prevent backplate from coming off；Two reinforcement gussets are additionally set, and strengthen the lower end of gusset to
Under extend to be connected with two mounting rails, the most also can increase the bonding strength of backplate and mounting rail, the most also can improve backplate
Intensity, prevents backplate deformation or fracture；Backplate, baffle plate and reinforcement gusset one forging molding, relative to existing casting
Backplate, be greatly improved the bulk strength of backplate；The epimere of baffle plate forms lead-in chamfered, the bootable caterpillar chain of this lead-in chamfered
Rail is drawn close to centre, thus is accurately supported by thrust wheel.
In sum, protect chain mechanism and there is the backplate crossing function for reliable anti-crawler belt, it is possible to reliably protecting running part
Divide producing balanced forces, more can be prevented effectively from equipment sideslip in the process of walking.

Detailed description of the invention
Referring to figs. 1 through shown in Fig. 5, one protects chain mechanism, including two mounting rail 2 and two backplates 1, is used for preventing caterpillar chain rail
4 depart from thrust wheel 3.
Thrust wheel 3 is arranged on bottom track frame, parallel relative being arranged on bottom track frame of two mounting rails 2, and is positioned at
Roller 3 both sides, two backplates 1 are spaced and are relatively welded between two mounting rails 2, and are positioned at outside 3 liang of end flanges 31 of thrust wheel,
Caterpillar chain rail 4 is limited in be supported by thrust wheel 3 between two backplates 1, and the opposite face of two backplates 1 is respectively arranged with and is positioned at Zhi Chong
Two baffle plates 11 of flange 31 both sides of wheel 3, the upper end of baffle plate 11 is higher than the top of thrust wheel 3 flange 31 to stop caterpillar chain rail 4
Jumping onto thrust wheel flange 31, the back of two backplates 1 is respectively arranged with the two reinforcement gussets 12 relative with its two baffle plate 11, and two add
The lower end of strong gusset 12 and two baffle plates 11 all extends downward welds with two mounting rails 2, strengthens gusset 12, baffle plate 11 and backplate 1
Integrally forging molding.
Two baffle plates 11 of backplate 1 symmetrical and all tilt extend, and make the spacing between two baffle plates 11 from bottom to up by
Tapered little, concrete baffle plate 11 is substantially inclined upwardly from the radial height of flange 31 and extends to the top of high pressure flange 31, baffle plate
The thickness of 11 is gradually increased from bottom to up, and baffle plate 11 and reinforcement gusset 12 are each perpendicular to backplate 1 and arrange, baffle plate 11 backplate 1 dorsad
Side epimere be formed with the lead-in chamfered 111 for guiding caterpillar chain rail accurately to be supported by thrust wheel 3, baffle plate 11 backplate dorsad
The side of 1 is inside flange 31 between 311 and outside 312, and near inner side 311, thus does not affect thrust wheel 3 and chain rail 4
Cooperating.
Above-mentioned drawing and describe all by real use state protect chain mechanism inversion on the basis of.
The above, preferred embodiment the most of the present utility model, therefore this utility model can not be limited with this and implement
