Background technology
At present, machine, cement or asphalt pavement machine are excluded in various caterpillars, such as excavator, appearance of the city working rig, road surface
Various vehicles, in order to avoid metal crawler belt directly contacts road surface and produces huge noise, meanwhile, also for protection road
Face, and increase the service life of crawler belt, rubber track plate can be increased outside crawler belt, to protect road surface and be protected when equipment moves
Road maintenance face.Existing rubber slab easily comes off from crawler belt iron plate in use, meanwhile, work larger for some weight
For the heavier equipment of load, the rubber slab on its crawler belt easily wears, and the rubber slab after abrasion does not have protection crawler belt
Effect, while the balance of equipment can be substantially reduced.
The content of the invention
In view of the above-mentioned problems of the prior art, the present invention provides a kind of polyurethane creeper tread, the creeper tread wearability
Can be good, rubber slab is difficult for drop-off.
To achieve these goals, the present invention provides a kind of polyurethane creeper tread, including the crawler belt iron plate of interconnection and
Crawler belt offset plate, and clamping screw, the crawler belt iron plate include and are adjacent to the lower surface one of chain, are away from the upper surface of chain
First, the caulking groove of upper surface one and a plurality of open-works through between lower surface one and caulking groove are hollowly arranged at；The caulking groove
Openend has a pair or so boss portions close to each other, and its bottom has a pair or so mutually remote circle recesses；The crawler belt
Offset plate is made up of compound polyurethane material, and the crawler belt offset plate includes the lower convex portion being embedded in the caulking groove；The lower convex portion
Lower end left part and right part there is the male part of cooperation of being fastened with the round recess, the upper end left part and right part of lower convex portion be with
The boss portion fastens the inner fovea part of cooperation；The position that the crawler belt offset plate bottom corresponds to the open-work offer it is a plurality of with
The corresponding screwed hole of the open-work；The internal package of the crawler belt offset plate has connecting framework, and the connecting framework is by section
The main body of rectangle, the multiple projections one for being spaced apart and arranged in body top center and fore-and-aft direction extension, it is spaced apart and arranged in master
Body upper end left part and right part and multiple projections two of fore-and-aft direction extension；The screwed hole is embedded at the connecting framework for fixation
The screw of middle nut；The clamping screw, which sequentially passes through corresponding open-work and screwed hole and fixes crawler belt iron plate and crawler belt offset plate, to be connected
Connect.
In the technical scheme, using crawler belt offset plate made of compound polyurethane material, crawler belt offset plate is effectively increased
Anti-wear performance, and then improve the service life of crawler belt offset plate.Connecting framework is embedded in the inside of crawler belt offset plate, can facilitate crawler belt
Installation and removal between offset plate and crawler belt iron plate, meanwhile, it can also increase the bonding strength between connecting framework and crawler belt offset plate,
The setting of projection one and projection two can be further ensured that connecting framework and the more preferable bonding strength of crawler belt offset plate, and be not easily stripped.
By making screwed hole be formed by the screw being embedded in the nut inside connection internal frame, can be easy to process, meanwhile, also allow for connecting
Clamping screw.The setting of caulking groove and lower convex portion can be such that the bottom of crawler belt offset plate is embedded on crawler belt iron plate, from regardless of whether using
When being changed after preceding assembling or abrasion, operation can be more convenient, meanwhile, crawler belt offset plate is not easy to crawler belt iron plate in operation process
Separation.The creeper tread anti-wear performance is good, and rubber slab is difficult for drop-off.
Further, the upper surface middle part of the crawler belt offset plate is plane, and its left and right ends is globoidal structure.
Further, the quantity of the open-work and screwed hole is four, and the lower surface one of the crawler belt iron plate is under open-work
The periphery in portion is additionally provided with counterbore.
