Description
Technical Field
The utility model relates to a bucket rod limiting device of a WK-10B type mining excavator, and belongs to the technical field of mining equipment.
Background
In the process of one cycle of the excavating operation, the bucket rod of the WK-10B type mining excavator frequently extends and retracts, and most of the time, because the operation site is complex, the bucket rod needs to retract to the limit position, and the protruding part at the front end of the bucket rod needs to impact the saddle to play a role in limiting the retraction of the bucket rod. The limit mode has the advantages that the damage to the saddle is relatively large, the eccentric wear of the saddle shaft sleeve is easy to occur, when the bucket rod is limited and impacts the saddle, the saddle can form bending stress on the pushing shaft, and the pushing shaft is easy to break under the action of bending force for a long time. In addition, during equipment maintenance, pushing system components such as the bucket rod, the saddle shaft sleeve, the pushing shaft and the like are required to be detached and installed, and because the weight of each component is large and the operation position is high, more manpower and auxiliary equipment are required during maintenance, the maintenance and replacement process is tedious, the maintenance cost is high, the maintenance time is relatively long, the influence on production is relatively large, and therefore improvement is required.
Disclosure of Invention
The utility model aims to provide a bucket rod limiting device of a WK-10B type mining excavator, which avoids the impact of the bucket rod on a saddle, shortens the moment of bending stress on a pushing shaft during limiting and solves the problems in the prior art.
The technical scheme of the utility model is as follows:
a bucket rod limiting device of a WK-10B type mining excavator comprises a front baffle, a supporting plate, a bucket rod, a rack, a pushing gear, a pushing shaft and a saddle, wherein the pushing gear is fixed on the pushing shaft, and the pushing shaft is rotatably connected to the saddle; the section of the bucket rod is rectangular, racks meshed with the pushing and pressing gears are arranged in the length direction of the bucket rod, the two front baffles are respectively fixed on the bucket rod and connected together through the supporting plate, and one ends of the two front baffles are arc-shaped matched with the pushing and pressing gears.
The rack meshed with the pushing gear in the length direction of the bucket rod is of an integrated structure with the bucket rod.
The two front baffles and the supporting plate are fixedly connected into an I-shaped structure.
The pushing shaft is provided with a clamp matched with the saddle.
A limit baffle is arranged between the bucket rod and the saddle.
The limit baffle between the bucket rod and the saddle is a right triangle.
The saddle is provided with a round hole matched with the pushing shaft.
The size and materials of the front baffle and support plate when installed are determined by the following factors: firstly, the normal operation of the pushing mechanism cannot be influenced after the front baffle is additionally arranged on the bucket rod; secondly, when the bucket rod is mechanically limited, the front baffle plate receives the impact load of the bucket rod; thirdly, stress generated by welding the front baffle on the bucket rod needs to be avoided at a position where the stress of the bucket rod is concentrated, and the bucket rod is prevented from being easy to fail due to the fact that a novel limiting device is additionally arranged; fourthly, when limiting, the arc edge size of the front end of the front baffle plate is completely matched with the size of the pushing gear when the front end of the front baffle plate contacts with the edge of the pushing gear, so that the limiting contact surface and the limiting resistance can be maximized, and the service life of the limiting device is prolonged; fifthly, cost and supporting strength.
The beneficial effects of the utility model are as follows: according to the utility model, the original telescopic rod limiting mode of the pushing mechanism of the WK-10B mining excavator is changed into the limiting mode that the bucket rod is additionally provided with the front baffle, so that the impact of the bucket rod on the saddle is avoided, the moment of bending stress on the pushing shaft during limiting is shortened, the deflection abrasion of the saddle shaft sleeve is reduced, the service life of the saddle shaft sleeve is prolonged, the equipment failure caused by the damage of the saddle or the pushing shaft is reduced, and the equipment failure rate is reduced.
