Abstract: The invention relates to a locking device designed to lock objects to tubes or other elongated elements. The locking device generally comprises one or more lock plates and lock housings. In one exemplary embodiment, when assembling the locking device to a tube, two lock housings are put together with open sides against each other around a tube with a dimension corresponding to approximately half of a recess which is found on the lock housing's sides and are oriented in the tube's axial direction. The two lock housings form a closed geometry around the tube. Lock plates are used to connect the two lock housings together. By applying a screw in a threaded hole in one of the lock housings' cover, the through tube is pressed against an opposite lock housing at substantially the same time as the lock plates hold the lock housings together.

Abstract: A rock drill telescopic arm is provided having a fixed arm which is sleeved on a movable arm; a telescopic oil cylinder; a plurality of adjusting blocks in the fixed arm along a circumferential direction thereof; a plurality of adjusting screw rods for respectively adjusting the position of each of the adjusting blocks on the fixed arm; a wear-resistant sliding block between at least part of the adjusting blocks and the movable arm; and a retainer at an opening end of the fixed arm for preventing the wear-resistant sliding block from moving along a telescoping direction of the movable arm, wherein the movable arm can be driven by the telescopic oil cylinder to slide along the wear-resistant sliding block. A rock drill equipped with the rock drill telescopic arm provides for convenient adjustment of a gap between the fixed arm and the movable arm.

Abstract: A telescopic roller conveyor is provided, the telescopic roller conveyor comprises an inner profile (1) and an outer profile (2). The inner profile (1) is adapted to slide inside the outer profile (2) such that a telescopic functionality is achieved. The inner (1) and outer (2) profiles each have a first side (3) comprising: at least one first recess (8) adapted to partly contain at least one roller organ (6) and at least one second recess (4) adapted to receive an axle (5) connected to the roller organ (6). The axle (5) is adapted to lock the inner (1) and outer (2) profiles to each other in the length axis of the profiles (1;2) when the axle (5) is placed in the recess (4). A telescopic roller conveyor frame is also provided.
