Abstract
The utility model discloses an installation device of an excavator work lining and belongs to the technical field of excavators. The installation device of the excavator work lining comprises a support seat, a fastening round nut, a bearing, an opening round baffle, an anti-slipping rod, a press plate round nut, a lead screw, an anti-falling nut and a rocking handle, wherein a thread hole matched with the lead screw is arranged in the inner wall of the press plate round nut, two thread holes matched with ends of the anti-slipping rod are formed in the press plate round nut longitudinally, the anti-falling nut is installed at one end of the lead screw, and the rocking handle is installed on a hexagonal prism which is arranged at the outer end of the anti-falling nut. An outer circle of the bearing is matched with the support seat, and an inner circle of the bearing is fixed with a stepped shaft on the other end of the lead screw through the fastening round nut. A stepped hole is formed in the inner wall of the support seat, and a round groove is formed in the outer wall of the support seat and is matched with the opening round baffle. The installation device of the excavator work lining is suitable for excavators which are used for construction in places like a mine far away from a maintaining site, so that time of returning for maintenance due to need for lining replacement is saved. The installation device of the excavator work lining has broad market prospect due to the advantages of being low in cost, simple in structure, convenient to carry, free from limit of sites and the like.
Description
Technical field
The utility model relates to a kind of excavator, and specifically a kind of erecting device of excavator work lining belongs to the excavator technical field.
Background technology
Traditional excavator working lining is enclosed within installation method and usually adopts press machine tool or manually adopt hammer that lining is pounded into, pounds with hammer to take time and effort, and installation effectiveness is low, and constantly knocks and unbalance stress, and lining is easy to damage; Press machine tool is the instrument that generally uses in the assembling process in batches, but has the problems such as place restriction and carrying be inconvenient, and more resleeve is particularly inconvenient for the place away from press machine tool of constructing outside.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of erecting device of excavator work lining, not limited by the place, effectively avoid impulsive force and easy to carry, can solve outside that construction needs back factory to reprocess difficulty, the problem such as waste time.
To achieve these goals, the technical solution adopted in the utility model is: a kind of erecting device of excavator work lining, comprise bearing, fastening round nut, bearing, the open circles baffle plate, antiskid bar, the pressing plate round nut, screw mandrel, screwed retaining ring and rocking handle, pressing plate round nut inwall is provided with the screwed hole that cooperates with leading screw, vertically have two screwed holes that cooperate with anti-skidding rod end along the pressing plate round nut, screwed retaining ring is installed in leading screw one end; rocking handle is installed on six prisms of screwed retaining ring outer end; bearing outer ring cooperates with bearing; inner ring and leading screw other end multidiameter are fixed by fastening round nut; the bearing inwall has stepped hole, and outer wall has circular trough and cooperates with the open circles baffle plate.
Further, the bearing middle part has two through holes that cooperate with antiskid bar; Antiskid bar one end is provided with screw thread and cooperates with the pressing plate round nut, and remainder is that polished rod cooperates with bearing.
The beneficial effects of the utility model: compare with traditional erecting device, the utility model is simple to operate, and is easy to carry, not limited by the place, is easy to make, safe and reliable, with low cost; Drive the leading screw rotation by rocking handle during installation, the rotation of leading screw promotes the pressing plate round nut and moves along the lead screw shaft direction, and the pressing plate round nut moves exerts pressure to lining, and lining slowly is pressed in the equipment support holes; The utility model is compared safer with the conventional mounting device, the excavator away from the construction in maintenance place such as be more suitable in the mine, saved because of resleeve more and need return the time of maintenance, because cost is low, simple in structure, easy to carry, be not subjected to the advantage such as place restriction, the utility model will have boundless market prospects.
