Further, the rubber ring 118 is sleeved on the two stabilizer bars 117, so that damage to the inner wall of the protection bin 113 caused by the fixed cylinder 110 due to excessive rotation of the screw rod 114 can be reduced, and the connecting rod 212 is broken due to excessive sliding of the sliding block 211 in the sliding groove 210, so that the device is not easy to damage to a certain extent.
Further, the sliding mechanism 2 includes a sliding groove 210, the sliding groove 210 is provided on the fixed cylinder 110, a sliding block 211 is slidably mounted in the sliding groove 210, a connecting rod 212 is fixedly mounted on one side of the sliding block 211, and one side of the connecting rod 212 is connected to the inner wall of the protection bin 113, so that the drill bit 115 can be more smooth when being adjusted, and meanwhile, the protection bin 113 cannot be shifted in the horizontal direction in the process of rising or lowering, that is, the guidance of the drill bit 115 is improved.
Further, rebound groove 213 has been seted up to one side of slider 211, extrusion groove 215 has been seted up to one side of connecting rod 212, fixed mounting has spring beam 214 in rebound groove 213, and in spring beam 214's one end extended to extrusion groove 215, exhaust hole 216 has been seted up to one side of spring beam 214, and the quantity of exhaust hole 216 is two, can reduce the influence of the vibration that this device normally produced to spout 210 and slider 211 like this, make spout 210 and slider 211 be difficult to damage because of the vibration more.
Further, the fixing mechanism 3 includes a first adsorption groove 310, the first adsorption groove 310 is disposed at the bottom end of the drill bit 115, a first insert block 311 is inserted into the first adsorption groove 310, the first insert block 311 is connected to the protective cylinder 111, a first magnet pad 312 is fixedly mounted in an empty groove disposed at one end of the first insert block 311, second adsorption grooves 313 are disposed at the bottom ends of the drill bit 115 around the first adsorption groove 310, second insert blocks 314 are inserted into four second adsorption grooves 313, the second insert blocks 314 are connected to the protective cylinder 111, second magnet pads 315 are fixedly mounted in empty grooves disposed at one ends of the four second insert blocks 314, a set of clamps and mechanisms 4 are disposed at two sides of the first adsorption groove 310, and each set of clamps and mechanisms 4 is three, rapid disassembly of the drill bit 115 is achieved through the action of adsorption limiting, the structure is simple, and convenient for a worker to operate, and the drill bit 115 and the protective cylinder 113 are better connected together by using a plurality of second adsorption grooves 313, the inconsistent rotation speed of the drill bit 115 and the protection cabin 113 is avoided.
Further, card and mechanism 4 include draw-in groove 410, and draw-in groove 410 is seted up on first inserted block 311, and fixed mounting has spring block 411 on the inner wall of draw-in groove 410, has seted up arc wall 412 on the inner wall of first adsorption tank 310, can fix drill bit 115 better like this under the prerequisite that does not influence the quick dismantlement of drill bit 115, prevents that drill bit 115 from droing because gravity is too big when not working, has further promoted the stability of this device.
The working principle is as follows: when the device is used by a worker, the screw rod 114 is controlled to rotate through the control panel on the heading machine, the screw rod 114 rotates to jack up the protection bin 113 due to the mutual matching of threads, so that the position of the drill bit 115 is changed, the sliding block 211 moves in the sliding groove 210 when the protection bin 113 moves, and the normal heading work of heading and moving upwards can be carried out after the position is adjusted.
When the device normally works, the fixed cylinder 110, the protective cylinder 111 and the drill bit 115 are controlled to rotate together by the tunneling machine, vibration generated during working can be transmitted to the connecting rod 212 from the protective cylinder 111, the connecting rod 212 can extrude the spring rod 214, the spring rod 214 can convert pressure into elastic potential energy, force applied to the sliding block 211 is reduced, and when the pressure is overlarge, the spring rod 214 can be inserted into the extrusion groove 215, so that the spring rod 214 can extrude air in the extrusion groove 215, the air can be exhausted from the exhaust hole 216, and corresponding resistance feeling can be brought.
When the drill bit 115 needs to be replaced, the adsorption limit can be removed only by clamping the drill bit 115 through mechanical equipment and lifting the drill bit upwards, meanwhile, the arc-shaped surface on one side of the spring block 411 is extruded and can be removed from the limit of the arc-shaped groove 412, and then the new drill bit 115 is replaced according to the same steps.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
