Description
Technical field
The utility model relates to a kind of three-point fix linkage of mining crawler unit.
Background technology
At present, in the crawler unit that development machine uses, creeper undercarriage mostly is coupling type with the syndeton of body support body and is connected, on creeper undercarriage, stretch out two junction plates, below two junction plates, make hook-type, utilize hook-type to hook body frame, because the width of groove is slightly larger than the thickness of body frame junction plate, machine is in use easily loosening due to the effect of external force, and hook produces gap, and bolt is easily cut off, stop and keep in repair, affect the service efficiency of development machine.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned shortcoming, a kind of three-point fix linkage is provided, the syndeton that it has mainly solved creeper undercarriage and body support body in the crawler unit that development machine uses is connected for coupling type, machine is in use because the effect of external force is easily loosening, hook produces gap, bolt is easily cut off, and the maintenance of stopping affects the problem such as service efficiency of development machine.The purpose of this utility model is achieved in that three-point fix linkage is made up of: walking mechanism, junction plate, the first alignment pin, connecting bolt, the second alignment pin, the 3rd alignment pin.Junction plate is welded in walking mechanism, on junction plate, boring has three dowel holes, the first dowel hole is positioned at the upper end of junction plate, the second dowel hole is positioned at a side of junction plate lower end, the 3rd dowel hole is positioned at the opposite side of junction plate lower end, and the first alignment pin is arranged in the first dowel hole, and the second alignment pin is arranged in the second dowel hole, the 3rd alignment pin is arranged in the 3rd dowel hole, and connecting bolt is arranged on junction plate.This product structure is simple, reasonable in design, and its adopts the connected mode of three-point fix pin to be connected with body frame, connects fasteningly, is not easy to become flexible, and bolt is not easy to cut off, and installing/dismounting is easy to maintenance, the operating efficiency of improved the installation of development machine down-hole, dismantling.
