Description

Technical Field

[0001] The utility model relates to the technical field of on-site protection of electric shovels in open-pit mines, and particularly relates to a sliding guide body for the saddle body of a Wk-type excavator. Background Technique

[0002] At present, the WK-10M3 electric shovel is one of the main excavation equipment in the Baiyun Iron Mine stope. There are 9 WK-10M3 electric shovels in the Baiyun Iron Mine, including 6 in the main mine and 3 in the east mine. Since the WK-10M3 electric shovel equipment was put into use, the wk-10m 3 The scientific name of the handle of the electric shovel is the saddle body, which we commonly call the handle. The function of the handle is to ensure that the shovel rod does not bounce up and down or swing left and right during operation. It is one of the important components of the push-pull mechanism. If the handle falls off, the shovel rod will not be able to work properly. In previous years, the handle often fell to the ground. The handle of the Wk-10 type excavator is different from that of the wk-4 and wk-20 type excavators. It is not a box-type structure but a semi-open structure. It relies on the handle copper sleeve to sleeve on the push-pull large shaft, and the clamp on the push-pull large shaft prevents the handle from slipping out and falling off the push-pull large shaft. Because only the handle copper sleeve supports the handle in the semi-open structure, the handle will swing left and right under the action of inertia when the electric shovel rotates. When swinging, the force is transmitted to the handle copper sleeve, and the symmetric stress points of the copper sleeve become thinner after being impacted for a long time. After becoming thinner, the copper sleeve gradually undergoes eccentric wear when rotating on the push-pull large shaft. When the eccentric wear amount of the copper sleeve gradually increases, it can be directly seen that the handle falls outward. After falling outward, the handle first gives an outward pressure to the handle clamp, causing the clamp to deform. When the pressure is large, the clamp screw will be broken and the clamp will fall off. If not discovered in time, the handle will fall to the ground. Without the clamp, the handle will fall to the ground after five working cycles of the electric shovel, resulting in the shutdown of the electric shovel due to a malfunction. Therefore, after it is found that the copper sleeve is severely eccentrically worn, it must be replaced in time to prevent the handle from falling to the ground. However, the eccentrically worn copper sleeve has not reached the normal service life of the copper sleeve, resulting in waste of spare parts. Secondly, after the handle falls outward, the clearance of the positive slide plate becomes larger, and pads must be added to the positive slide plate. However, after adding the pads, the handle falls outward more severely, resulting in a smaller contact surface between the positive slide plate and the shovel rod, and the positive slide plate undergoes eccentric wear. Grooves will be worn out on the contact surface between the positive slide plate and the edge of the shovel rod, and the positive slide plate will also be used up to the limit in advance. This requires the electric shovel driver to conduct spot checks and replace the worn parts, increasing the cumbersome maintenance procedures and the labor intensity. In order to improve the operation efficiency and reduce the labor intensity, we have carried out technical improvements to change the current situation of difficult sliding guidance of the electric shovel.
