Detailed Description
An embodiment of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways, which are defined and covered by the claims.
As shown in fig. 2, the utility model discloses drilling machine feeding hoist mechanism's protecting against shock device 7 embodiment is including the chain joint 71 that connects gradually, adjust the swivel nut 73, adjusting screw 74, board-like chain fixed plate 61, belleville spring 75, bearing nut 76, the both ends of adjusting the swivel nut 73 set up positive and negative screw thread, and the one end of chain joint 71 and the dead point end of lifting plate chain 1 or feeding plate chain 5 are connected, the other end passes through threaded connection with the one end of adjusting the swivel nut 73, the other end of adjusting the swivel nut 73 passes through the one end of threaded connection adjusting screw 74, the both ends of adjusting the swivel nut 73 set up respectively and are used for preventing to adjust the not hard up lock nut 72 of swivel nut 73, board-like chain fixed plate 61 cover is established at the other end of adjusting screw 74, be located and set up belleville spring 75 and bearing nut 76 on the adjusting screw 74. The plate-type chain fixing plate 61 is fixedly connected to the tower 6.
As shown in fig. 3, when the hydraulic cylinder plate type chain feeding lifting mechanism is used, the movable ends of the lifting plate type chain 1 and the feeding plate type chain 5 are fixed on the power head 2, and then the other ends of the lifting plate type chain 1 and the feeding plate type chain 5 walk around the feeding pulley 8 and the upper pulley or the lower pulley of the traveling pulley block 4, and finally the dead point ends of the lifting plate type chain 1 and the feeding plate type chain 5 are fixed on the chain joint 71 of the impact protection device 7, and the adjusting screw 74 is connected with the plate type chain fixing plate 61 on the tower 6. When oil is fed into a rod cavity of the hydraulic oil cylinder 3, the piston rod drives the traveling pulley block 4 to move upwards, and the power head 2 realizes downward feeding motion. The bottom of the hole can generate high-frequency vibration impact force during the drilling process of the drilling machine, particularly during the drilling process of the down-the-hole hammer, and the disc spring 75 automatically generates elastic deformation according to the vibration impact force of the bottom of the hole, so that most vibration impact energy is absorbed, and the drilling machine and the drilling tool are protected. In a similar way, the oil is fed into the rodless cavity of the hydraulic oil cylinder 3, the piston rod pushes the traveling pulley block 4 to move downwards, and the lifting plate type chain 1 lifts the power head 2 to move upwards. When the lifting plate type chain 1 or the feeding plate type chain 5 is elongated, because the two ends of the adjusting screw sleeve 73 are provided with the positive and negative screw threads, the distance between the chain joint 71 and the plate type chain fixing plate 61 can be adjusted by loosening the locknuts 72 at the two ends of the adjusting screw sleeve 73 and rotating the adjusting screw sleeve 73, so that the purpose of adjusting the tensile deformation generated in the use process of the lifting plate type chain 1 or the feeding plate type chain 5 is achieved, the lifting plate type chain 1 and the feeding plate type chain 5 always keep proper pretension force and the chain is not dropped.
Further, even if the vibrations impact force at the bottom of the hole leads to belleville spring 75 to warp repeatedly among the drilling process, adjusting screw 74 and belleville spring 75, the continuous relative slip of pore wall of plate chain fixed plate 61, because the utility model discloses adjusting screw 74 and belleville spring 75 and plate chain fixed plate 61's pore wall relative slip position surface are the face of cylinder, do not have the external screw thread, have avoided the trouble that the regulation plate chain pretightning force function that screw thread wear and tear leads to loses.
