Abstract

The utility model relates to an automatic-control mine anchor rod dead-rusty nut splitter, which comprises a hydraulic nut splitter and a hydraulic power system capable of automatically unloading and loading oil pressure, wherein the hydraulic nut splitter comprises a working head, a shearing hole, a cutter, a return spring, a hydraulic pushrod and the like; and the hydraulic power system capable of automatically unloading and loading oil pressure comprises a hand hydraulic pump, an electromagnetic valve, a digital display pressure sensor, a power supply circuit box and the like. The nut splitter provided by the utility model has the advantages that the volume is small, the working performance is good, the nut splitter can be used with the hydraulic power system capable of automatically unloading and loading oil pressure in a matched way, whether nut splitting is completed or not can be automatically recognized, the splitting accuracy is high, sparks are not generated and the nut splitter is suitable for all fireproof and explosion-proof fields.

Description

Can control the broken device of cutting of mining anchor pole rust nut cap automatically

Technical field

The utility model relates to a kind ofly can control the broken device of cutting of mining anchor pole rust nut cap automatically.

Background technology

In the dark wet environment in down-hole, mine, the anchor nut dead phenomenon of very easily becoming rusty, in case rust is dead, common extracting tool is powerless at all, give anchor pole dismounting, reclaim and bring very big difficulty.

For many years, less to the research of the broken cutting apparatus of mining anchor pole rust nut cap, whether the broken cutting apparatus operation of existing nut inconvenience needs broken the cutting of artificial cognition to accomplish, and the broken precision of cutting is not high, is damaged to the body of rod of anchor pole easily.

Summary of the invention

The technical problem underlying that the utility model will solve is: solve the problem that the anchor nut rust is dead, be difficult to dismantle; Provide a kind of nut cap that will become rusty fast and efficiently broken cutting; And can discern broken the cutting of nut automatically and whether accomplish, broken cut precision high can control the broken device of cutting of mining anchor pole rust nut cap automatically.

The utility model adopts following technical scheme to realize: hydraulic nut breaks on the working head of cutting the device front end has the shearing perforation that can hold nut; A through hole is arranged on the hole wall of shearing perforation; Slidably hydraulic push rod is installed in the through hole, and hydraulic push rod one side is installed cutting knife, and opposite side links to each other with hydraulic cylinder; The tail end of working head has external screw thread, and the front end of hydraulic cylinder has internal thread, and working head is connected through the screw thread mount with hydraulic cylinder; Between hydraulic push rod and the working head retracting spring is installed.The hydraulic power system that can unload oil pressure voluntarily is made up of parts such as hydraulic hand-pump, magnetic valve, digital display type pressure sensor, power circuit casees; Hydraulic hand-pump is connected through pipeline with the digital display type pressure sensor; The power circuit case is installed on the pedestal of hydraulic hand-pump, and the power circuit case is connected with the digital display type pressure sensor with magnetic valve respectively.The broken oil connection of cutting device of nut has internal thread, and the oil connection of hydraulic power system has external screw thread, and both are through being threaded.

During operate as normal, at first cut device and be threaded through pipe joint nut is broken, secondly will break and cut the device working head and be enclosed within on the nut that needs shearing with hydraulic power system; Manual operation hydraulic pump depression bar then, hydraulic oil promotes hydraulic push rod and presses to nut, and the contact nut begins brokenly to cut; When pressure sensor detects the oil pressure jump signal, pass the signal along to the power circuit case, the power circuit case sends control signal and gives magnetic valve; Magnetic valve is opened, the oil pressure of unloading hydraulic cylinder, and hydraulic push rod returns to original position under the effect of retracting spring; Closed electromagnetic valve, nut is broken to cut.

The good effect of the utility model: nut is broken, and to cut body long-pending little, easy and simple to handle, and service behaviour is good; Whether cooperation can unload the hydraulic power system of oil pressure voluntarily and use, can discern broken the cutting of nut automatically and accomplish, the broken precision height of cutting; No-spark produces, and is applicable to various fire prevention, explosion-proof field.

Description of drawings

Fig. 1 is the broken overall structure sketch map of cutting device of hydraulic nut;

Fig. 2 is for can unload the sketch map of the hydraulic power system of oil pressure voluntarily.

The specific embodiment

The utility model can control automatically that mining anchor pole rust nut cap is broken cuts device, comprises broken device and the hydraulic power system that can unload oil pressure voluntarily of cutting of hydraulic nut.As shown in Figure 1, hydraulic nut is broken to be cut device and comprises parts such as working head 1, cutting knife 3, hydraulic push rod 4; Wherein, the shearing perforation that can hold nut 2 is arranged on the working head 1, shearing on the hole wall has a through hole, and slidably hydraulic push rod 4 is installed in the through hole, and push rod 4 is installed cutting knife 3 near shearing perforation one side, and opposite side is communicated with hydraulic cylinder 6; The tail end of working head 1 has external screw thread, and the front end of hydraulic cylinder 6 has internal thread, and both are through the screw thread assembling; Between working head 1 and the hydraulic push rod 4 retracting spring 5 is installed.As shown in Figure 2, the hydraulic power system that can unload oil pressure voluntarily comprises parts such as hydraulic hand-pump 8, magnetic valve 9, power circuit case 10, digital display type pressure sensor 11; Hydraulic hand-pump 8 and digital display type pressure sensor 11 are connected through pipeline; Depression bar 12 provides power for hydraulic hand-pump 8; Power circuit case 10 is installed on the pedestal of hydraulic hand-pump 8, and power circuit case 10 is connected through circuit with magnetic valve 9 and digital display type pressure sensor 11 respectively.

When the utility model uses, at first will break and cut device oil connection 7 and is connected, and be enclosed within needs to the broken working head of cutting device then and break on the nut 2 that cut with hydraulic power system oil connection 13; Manual operation depression bar 12 makes hydraulic oil pass through oil pipe and gets into hydraulic cylinder 6, and the cutting knife 3 that hydraulic oil promotes on the hydraulic push rod 4 is pressed to nut 2, and contact nut 2 begins brokenly to cut; When digital display type pressure sensor 11 detects the oil pressure jump signal; Pass the signal along to power circuit case 10, power circuit case 10 sends control signal and gives magnetic valve 9, and magnetic valve 9 is opened; Begin to unload the oil pressure in the hydraulic cylinder 6; Hydraulic push rod 4 returns to original position under the effect of retracting spring 5, magnetic valve 9 cuts out, and nut is broken to cut.
