For the construction machinery product that adopts the crawler body structure, such as crawler crane, excavator, revolve and dig brill etc. and the creeper tread phenomenon of rupture often can occur, need to change creeper tread.The creeper tread of dismantling and damaging, unspoiled creeper tread can come off from track frame because being subject to Action of Gravity Field.For preventing that creeper tread from coming off, prior art is with whipline, creeper tread to be sling, and with the method for manual adjustment, makes the hole alignment of creeper tread when creeper tread is installed, and completes more changing jobs.Adopt this method, need whipline that creeper tread is sling, and certain danger is arranged during removing damaged creeper tread, waste time and energy when creeper tread is installed.
Summary of the invention
The technical problem to be solved in the present invention is the technical deficiency for above-mentioned existence, provides a kind of simple in structure, easy to use, can play fixation to creeper tread, and creeper tread for convenience detach and that change is changed instrument.
For solving the problems of the technologies described above, the invention provides a kind of creeper tread and change instrument, comprise the first knee, the second knee, adapter sleeve, connecting rod and nut;
The first knee is L-shaped, comprises horizontal segment and vertical section, and the first knee horizontal segment and vertical section end have one section external screw thread;
The second knee is L-shaped, comprises horizontal segment and vertical section, and the second knee horizontal segment end has one section screwed hole, and vertically a section end has one section external screw thread;
Adapter sleeve is cylindricality, the adapter sleeve left end has screwed hole, the internal thread of screwed hole coordinates with the external screw thread of the first knee horizontal segment, the first unthreaded hole is arranged in the middle of adapter sleeve, right-hand member has the second unthreaded hole, the common straight line of the axis of the first unthreaded hole and the second unthreaded hole, the first unthreaded hole communicates with the second unthreaded hole, and the diameter of the first unthreaded hole is greater than the diameter of the second unthreaded hole;
The connecting rod left end has the step of protrusion, and the connecting rod right-hand member is thread segment, and the external screw thread of thread segment matches with the internal thread of the second knee horizontal segment screwed hole;
The horizontal segment of the first knee is threaded with the adapter sleeve left end, and the second knee horizontal segment is threaded with the connecting rod right-hand member, and the step of connecting rod left end is positioned at the first unthreaded hole of adapter sleeve, and vertical section of the first knee and the second knee is screwed with nut.
during use, back out the vertically nut of section of the first knee and the second knee, in vertical section of the first knee fabrication hole that inserts creeper tread one side creeper tread to be replaced, the nut of screwing on, turn adapter sleeve or turn connecting rod, regulate the distance between the first knee and the second knee, in vertical section of the second knee fabrication hole that inserts creeper tread opposite side creeper tread to be replaced, regulate adapter sleeve or connecting rod, adjust the rate of tension of crawler belt, make the connection bearing pin degree of tightness of creeper tread to be replaced suitable, take off bearing pin, take out the creeper tread that damages, put into new creeper tread, the pin upper pin, whole process does not need auxiliary lifting equipment, high efficiency, safe and reliable.
Beneficial effect of the present invention is: simple in structure, easy to use, can play fixation to creeper tread, and for convenience detach and replacing creeper tread has reduced workman's labour intensity.
Described connecting rod has a through hole between step and thread segment, adjusting rod is arranged in through hole, can regulate connecting rod by pulling adjusting rod, and is convenient, laborsaving.
Is milled with four planes in the middle of described adapter sleeve, can clamps adapter sleeve by convenient wrench, more laborsaving, the quantity on plane can be two, three, four, six etc.
