The automatic tool changing principle of the invention is as follows:
in the operation of the shield tunneling machine cutterhead, the top scraping cutter is positioned at the working position and participates in scraping rock and soil, the rest scraping cutters are not involved in scraping rock and soil, as shown in fig. 10, the scraping cutter Q is positioned at the working position, the hydraulic push rod and the rocker are in a reset state, the scraping cutter Q is supposed to be damaged, the scraping cutter K is intact, the scraping cutter K can rotate around the axis of the mandrel through continuous telescopic action of the hydraulic push rod, and then the scraping cutter K is enabled to replace the scraping cutter Q in position, so that the purpose of changing cutters is achieved.
The scraping tool realizes the rotation as follows:
step one: as shown in fig. 11, the hydraulic push rod pushes the rocker to swing by an angle A1, and simultaneously the scraping cutter Q rotates by an angle A1, and the stop pawl truncated cylindrical pin retracts to the corresponding base by a certain distance under the action of the ratchet teeth.
Step two: as shown in fig. 12, the rocker swings at an angle A2 under the pushing of the hydraulic push rod, at this time, the truncated cylindrical pin of the stop pawl reaches a critical point of being ejected outwards from the corresponding base, and at the next moment when the hydraulic push rod continues to push the rocker to swing, the truncated cylindrical pin ejects and is inserted into the adjacent tooth slot of the ratchet wheel, as shown in fig. 13, with the state of the hydraulic push rod shown in fig. 13 as a starting point, the hydraulic push rod will retract at the next moment.
Step three: as shown in fig. 14, the hydraulic push rod pulls the rocker to swing to an angle B1 (B1 < A2) in the opposite direction to the first step, in the process, the ratchet wheel is in a static state under the action of the stop pawl, and the truncated cylindrical pin pushing the pawl retracts to a distance corresponding to the base under the action of the ratchet wheel teeth.
Step four: as shown in fig. 15, the tapered cylindrical pin pushing the pawl reaches the critical point of ejecting from the corresponding base, and at the next moment when the hydraulic push rod continues to pull the rocker to swing, the tapered cylindrical pin ejects and inserts into the other tooth slot of the ratchet, and the hydraulic push rod and the rocker return to the reset state as shown in fig. 16.
As can be seen from the first to fourth steps, the hydraulic push rod completes one telescopic movement, the scraping cutter Q rotates by an angle A3, the angle between centers of adjacent scraping cutters is C, the relation between C and A3 satisfies the formula (1),
c=n.a3, (n is a positive integer) (1)
Therefore, the hydraulic push rod completes n times of telescopic actions, the scraping cutter K replaces the scraping cutter Q, and the cutter changing is realized.
In the actual tool changing process, the expansion and contraction of the hydraulic push rod are controlled by using an electromagnetic directional valve, an operator sends a tool changing instruction to a PLC by a computer in a main control room of the shield machine, and the PLC controls the electromagnetic directional valve configured by the hydraulic push rod to enable the hydraulic push rod to complete n times of expansion and contraction actions to realize tool changing.
