The utility model discloses an arm frame of a rock drilling platform, including an arm frame, and a dustproof device at the end of the arm body. The dustproof device comprises a circular mounting plate fixed on the end face of the arm frame, a seal ring and a cover plate for sealing the telescopic arm, and the middle part of the axial end face of the mounting plate is provided with the middle part of the outer end face of the mounting plate and the middle part of the outer end of the mounting plate is provided with the middle part of the axial end face of the mounting plate and the middle part of the outer end of the mounting plate is provided with the middle part of the axial end face of the mounting plate. The annular groove of the arm frame is arranged in the coaxial line. The seal ring is embedded in the annular groove, and the thickness of the seal ring is not less than the depth of the annular groove. The cover plate is matched tightly with the mounting plate, and the inner circumference of the seal ring is provided with the V lip with the opening of the center axis of the arm frame. When the telescopic arm and the arm frame are installed, the telescopic arm is in interference with the sealing ring, and the V lip mouth can be compressed and open by the telescopic arm, so as to close closely with the telescopic arm, effectively carry out the sealing protection and ensure the dust proof effect. The utility model also discloses a rock drilling trolley comprising the said rock drill trolley arm, and the dust proof effect of the end part of the rock drill trolley arm is good.

凿岩台车及其凿岩台车臂架
本技术涉及凿岩台车
,特别涉及一种凿岩台车臂架。此外,本技术还涉及一种包括上述凿岩台车臂架的凿岩台车。
技术介绍
凿岩台车在隧道中凿岩时,会产生许多粉尘。为避免臂架在伸缩过程中,将粉尘等大颗粒杂质等带入臂架内部,导致滑块过渡磨损,需在臂架端部设置防尘装置。然而,目前的防尘装置的密封性较差,从而导致防尘效果较差。因此,如何保证防尘效果,是本领域技术人员目前需要解决的技术问题。
技术实现思路
有鉴于此,本技术的目的是提供一种凿岩台车臂架,防尘效果较好。本技术的另一目的是提供一种包括上述凿岩台车臂架的凿岩台车,其凿岩台车臂架端部的防尘效果较好。为实现上述目的,本技术提供如下技术方案:一种凿岩台车臂架,包括臂架本体,所述臂架本体的端部设有防尘装置,所述防尘装置包括固定连接于所述臂架本体的端面上的环状的安装板、用于与伸缩臂相密封套设的密封圈和盖板;所述安装板的轴向外端面的中部设有与所述臂架本体同轴设置的环形凹槽,所述密封圈嵌设于所述环形凹槽中,且所述密封圈的厚度不小于所述环形凹槽的深度,所述盖板与所述安装板相配合夹紧所述密封圈,所述密封圈的内周设有朝向所述臂架本体的中心轴开口的V型唇口。优选地,所述安装板上沿径向贯穿设有注油孔,且所述注油孔的出口设在所述环形凹槽的周面与所述V型唇口的外周面之间的预留间隙中。优选地,所述安装板与所述盖板螺栓连接。优选地,所述注油孔为至少四个,且所有所述注油孔沿周向依次设置。优选地,所述安装板与所述臂架本体螺栓连接。优选地,所述环形凹槽呈喇叭状。优选地,所述注油孔的径向截面呈T形,且所述注油孔包括沿径向延伸的注油 ...
