The pin shaft locking device comprises a cylindrical pin shaft, a first protrusion is arranged at one end of the pin shaft, the first protrusion is in a semi-cylindrical shape, the diameter of the first protrusion is the same as that of the pin shaft, a locking plate is arranged on one side of the first protrusion, and a fixing plate is arranged on the other side of the first protrusion. The locking plate is provided with a plurality of first inserting holes, the fixing plate is provided with a plurality of second inserting holes, and the tightening bolts sequentially penetrate through the second inserting holes and the first inserting holes to be movably connected with the locking plate and the fixing plate. The problems that in the prior art, an underground forklift adopts a traditional pin shaft locking mode, due to the fact that two connecting parts need to be machined through traditional pin shaft locking, complete matching cannot be achieved in the assembling process due to the machining precision problem, and the assembling and maintaining efficiency is low can be solved; and the production efficiency and the maintenance efficiency of the underground carry-scraper can be improved, and the practicability is good.
本发明提供了一种用于井下铲运机的销轴锁紧装置,包括圆柱状销轴,所述销轴的一端部设有第一突起,所述第一突起呈半圆柱状,其直径与销轴的直径相同,所述第一突起的一侧设有锁紧板、另一侧设有固定板,所述锁紧板设有若干第一插孔,所述固定板设有若干第二插孔,所述拧紧螺栓依次穿过第二插孔、第一插孔,实现与锁紧板及固定板之间的活动连接。本发明能够解决现有技术中矿井下铲运车采用传统销轴锁方式,由于传统销轴锁紧需对连接双方进行加工,因加工精度问题导致装配过程出现无法完全匹配,致使装配和维修效率低下的问题,本发明无需加工锁紧面,能够提高井下铲运机的生产效率和维修效率,具有良好的实用性。
