The difference between the pallet clamp 38 and the cable clamp 46 is that the pallet clamp 38 enters from the side and the cable clamp 46 enters from below in different ways to insert the object, resulting in a shorter clamping hand 63 of the pallet clamp 38 (see the dotted line) to ensure smooth clamping. The clamping hand 63 adopts high-grade alloy steel for surface quenching, so that the wear-resisting strength is high, and the use reliability is ensured. The shape of the clamping hand 63 is matched with that of the tray C and the anchor cable, so that firm clamping and thorough separation are realized.
Further, as shown in fig. 5, the wire feeding and cutting assembly 4 further comprises a swing motor 52, the chain saw 51 is swingably connected to the cable clamp 46, and the swing motor 52 is adapted to drive the chain saw 51 to swing around the circumference of the tensioning cylinder. Therefore, after the anchor cable is tensioned by the tensioning cylinder, the swing motor 52 can control the chain saw 51 to cut the anchor cable, and the chain saw 51 rotates at a high speed until the anchor cable is cut off.
Specifically, as shown in fig. 5, the swing motor 52 drives the swing cam 53 to rotate, and the guide groove 55 of the swing cam 53 contacts with the sliding post 56 below the chain saw 51 to push the chain saw 51 to swing back and forth along the guide rail 54 to ensure that the anchor cable is completely cut off.
Specifically, after the cable feeding and cutting assembly 4 is abutted against the tray C, the cylinder rod 41 drives the anchor cable clamp 46 to extend, the anchor cable clamps air to loosen the anchor cable, the cable feeding motor 43 drives the conveying wheel 45 to feed the anchor cable into the anchor cable hole through the inner hole of the tray C along the tensioning oil cylinder, the cable feeding stops when the angle sensor 44 senses that the anchor cable is in place, after the medicament in the explosive cartridge a is solidified, the anchor cable is clamped by the anchor cable clamp 46, hydraulic oil enters the first cavity to press the cylinder rod 41 to retract so as to tension the anchor cable and achieve rated pressure, then the first cavity is sealed, the tray clamp 38 extrudes the root of the tray C to generate plastic deformation so as to be fixedly connected with the anchor cable, after the tray C is fastened with the anchor cable, the tray C is cut by using the chain saw 51 rotating at high speed, the pressure of the first cavity is reduced to zero after the anchor cable is completely cut, and the pressure sensor transmits a signal to the electrical control system.
Further, as shown in fig. 7, the chain saw 51 includes a driver 511, a chain 512, a blade 513, a driving wheel 514 and a driven wheel 515, the chain 512 is engaged with both the driving wheel 514 and the driven wheel 515, the driver 511 is used for driving the driving wheel 514 to drive the chain 512 to move, so that the chain 512 rotates between the driving wheel 514 and the driven wheel 515 at a high speed, and the chain 512 drives the blade 513 to cut the anchor cable quickly, so as to cut the anchor cable instantaneously.
As shown in fig. 8, the mechanical actions of the automatic drilling, pushing, feeding and tensioning fixed connection cutting mechanism are complicated, the logical relationship is complex, and the reliability is high, including a plurality of actions of anchor drilling (feeding, rotating), pushing, tray feeding, anchor cable tensioning, tray clamping, anchor cable cutting, emergency stop and the like, the complex mechanical structure and hydraulic accurate control are realized by adopting an industrial personal computer and a multi-field sensor with strong processing capability and an advanced control algorithm, the actions of the drill boom and the parameter matching of a hydraulic system are realized by adopting a modular programming language, and the execution part is realized by adopting a highly integrated electro-hydraulic control valve group.
