Detailed Description

A mining gas is cut, as shown in fig. 1, including power axle box 1, 1 front end fixed mounting of power axle box has two splint 2 of vertical setting, installs between splint 2 and cuts the sword, the flexible sword that can drive of output shaft in the power axle box 1 is cut and is opened and shut and accomplish the action of cutting the line. As shown in fig. 2 and fig. 3, the shearing knife includes two knife holders 3 hinged between the clamping plate 2, each knife holder 3 is provided with a mounting groove 4, the mounting groove 4 is connected with a rotating block 5 through a rotating shaft, the rotating block 5 is provided with a knife 6 through a set screw 18, when the cutting knife is in a use state, the sharp end of the knife 6 is located outside the clamping plate 2, and when the cutting knife is in a non-use state, as shown in fig. 5, the rotating block 5 can drive the knife 6 to rotate so that the sharp end of the knife 6 enters the mounting groove 4. Wherein the cutter 6 is detachably arranged on the rotating block 5 through a set screw 18, and the cutter 6 can be detached and replaced independently after the cutter 6 is damaged.

As shown in fig. 4, the bottom of the rotating block 5 is provided with a positioning block 7 arranged in parallel with the clamping plate 2, a first avoiding groove 8 is formed in the clamping plate 2 close to one side of the positioning block 7, a second avoiding groove 9 is formed in the clamping plate 2 far away from one side of the positioning block 7, the setting of the avoiding groove allows the rotating block 5 to drive the cutter 6 to rotate, a baffle 10 is hinged in the first avoiding groove 8, the baffle 10 rotates to open and close to seal or open the first avoiding groove 8, a detachable fastening plate 11 is further installed on the clamping plate 2, and the fastening plate 11 can compress the baffle 10 on the positioning block 7 so as to position the rotating block 5.

When the air shears are in a use state, as shown in fig. 4, the first avoiding groove 8 is sealed by the baffle 10, the baffle 10 is arranged in parallel with the positioning block 7, and the rotating block 5 and the cutter 6 which are positioned between the two clamping plates 2 cannot rotate under the limitation of the baffle 10, so that the normal operation of the thread shearing action is ensured. When the air shear is in a non-use state, and the sharp end of the cutter 6 needs to be rotated into the mounting groove 4, the fastening plate 11 at the position of the first avoidance groove 8 is firstly detached, the baffle plate 10 is rotated, the first avoidance groove 8 is opened, and then the rotating block 5 and the cutter 6 are rotated clockwise 180 degrees in the direction shown in fig. 4, as shown in fig. 5, the sharp end of the cutter 6 enters the mounting groove 4, then the baffle plate 10 is rotated to seal the first avoidance groove 8, the baffle plate 10 is positioned on the clamping plate 2 by the mounting fastening plate 11, so that the cutter 6 between the clamping plate 2 and the baffle plate 10 cannot rotate out of the clamping plate 2, the effective protection effect on the cutter 6 can be achieved, and the service life of the cutter can be prolonged to a certain extent.

When using the gas to cut, operating personnel is the single-hand grip hand generally and carries out the trimming operation, because the quality of ore deposit gas is cut is great, after using for a long time, can bring the strain of different degrees for user's wrist, for the intensity of labour who alleviates operating personnel wrist support 12 is installed to power axle box 1 bottom, support 12 bottom be equipped with arm matched with arc backup pad 13, the weight distribution that sets up of arc backup pad 13 can cut some gas to the arm on, alleviates the weight that the wrist bore.

Further, for the convenience of carrying by hand, a lifting handle 14 is mounted on the top of the power shaft box 1. Since the mass of the integral air shear is large, in order to ensure the strength of the power shaft box 1, a reinforcing rib 17 is further arranged on the periphery of the power shaft box.

Furtherly, for the convenience of carrying out dismouting and fixed mounting plate 11 on splint 2, the upper and lower both sides position of splint 2 front end all is equipped with bolt 15, and blade holder 3 is installed on bolt 15 and can be followed its rotation, and the through-hole with bolt 15 matched with is seted up at mounting plate 11 both ends, and bolt 15 passes splint 2, blade holder 3 and mounting plate 11 in proper order, and wears out bolt 15 one end cooperation of mounting plate 11 and install fastening nut 16, the through-hole play of mounting plate 11 one end sets up the heavy groove 19 of concentric setting, and heavy groove 19 cooperatees with fastening nut 16, still sets up the trough 20 that passes through with heavy groove 19 looks UNICOM on mounting plate 11. The fastening nut 16 can be a butterfly nut, so that the butterfly nut is convenient to rotate, disassemble and assemble, the sunk groove 19 can be matched with the fastening nut 16 to compress and position the fastening plate 11, the fastening nut 16 is screwed to enable the fastening plate 11 to be compressed on the baffle plate 10 to be positioned, the fastening nut 16 can be unscrewed to detach the fastening plate 11, the whole operation is relatively simple and convenient, the positioning and fastening are reliable, as shown in fig. 5, the fastening nut 16 on one side is allowed to be unscrewed due to the arrangement of the through groove 20, the fastening plate 11 is rotated to be separated from the baffle plate 10, and the compression and positioning of the baffle plate 10 by the fastening plate 11 can be.

Technical scheme of the utility model not be restricted to the utility model the within range of embodiment. The technical contents not described in detail in the present invention are all known techniques.
