In some embodiments provided by the present invention, the plug pin device further comprises an interlock lever 3. The interlock lever 3 is connected to a cylinder pin 9 of the cylinder head block 4, and the cylinder pin 9 drives the interlock lever 3 to a first position when retracted and drives the interlock lever 3 to a second position when extended. Specifically, the number of the interlock levers 3 is one pair, and the pair of interlock levers 3 corresponds to the pair of cylinder pins 9, respectively.
When the interlocking rod 3 is at the first position, the interlocking rod 3 limits the sliding seat 1, i.e. the interlocking rod 3 is clamped with the sliding seat 1 to limit the sliding of the sliding seat 1.
When the interlocking rod 3 is in the second position, the interlocking rod 3 releases the limit of the sliding seat 1 so that the sliding seat 1 can slide, and after the sliding seat 1 slides, the sliding seat 1 limits the interlocking rod 3, namely, the sliding seat 1 is clamped with the interlocking rod 3 so as to limit the retraction of the cylinder pin 9 through the interlocking rod 3.
In this embodiment, referring to fig. 1-5, when the cylinder pin 9 is retracted, the cylinder pin 9 drives the interlock lever 3 to the first position, and at this time, the interlock lever 3 can limit the sliding seat 1, that is, the interlock lever 3 limits the sliding seat 1 to slide, thereby preventing the pin pulling process, and realizing the protection effect that the arm pin 7 cannot be pulled out when the cylinder pin 9 is retracted. When the cylinder pin 9 is extended, the interlock lever 3 slides to the second position, and the interlock lever 3 releases the restriction of the slide block 1. After the sliding seat 1 slides, the sliding seat 1 is limited by the interlocking rod 3, and at the moment, the interlocking rod 3 cannot slide, so that the cylinder pin 9 cannot slide and retract, and the protection effect that the cylinder pin 9 cannot retract after the arm pin 7 is pulled out is realized.
By means of the arrangement, the interlock rod 3 is connected with the cylinder pin 9, and the cylinder pin 9 drives the interlock rod 3 to switch between the first position and the second position, so that the sliding seat 1 and the cylinder pin 9 can be interlocked through the interlock rod 3, namely, the arm pin 7 cannot be pulled out after the cylinder pin 9 is retracted, and the cylinder pin 9 cannot be retracted after the arm pin 7 is pulled out, so that the use safety of the pin inserting and pulling device is improved, and the safety problem caused by misoperation of operators is reduced.
Referring to fig. 3 and 4, in some embodiments provided by the present invention, a bar hole 401 is provided on the cylinder head block 4, the length direction of the bar hole 401 is the same as the sliding direction of the cylinder pin 9, and the interlock lever 3 is connected to the cylinder pin 9 through the bar hole 401 so that the interlock lever 3 can slide along with the sliding of the cylinder pin 9.
The sliding seat 1 is provided with a first clamping groove 101 and a second clamping groove 102 for clamping the interlocking rod 3, the extending direction of the first clamping groove 101 is the same as that of the strip-shaped hole 401, and the extending direction of the second clamping groove 102 is the same as that of the sliding seat 1.
Specifically, the first card slots 101 are provided in a pair, the pair of first card slots 101 are in one-to-one correspondence with the pair of interlocking bars 3, and the notches of the pair of first card slots 101 face both sides of the slide base 1, respectively. The second card slots 102 are provided in a pair, the pair of second card slots 102 are in one-to-one correspondence with the pair of interlocking bars 3, and the notches of the pair of second card slots 102 are all oriented in a direction in which the pair of guide structures 103 are away from each other. Alternatively, the first card slot 101 and the corresponding second card slot 102 form an L-shaped structure, e.g., the first card slot 101 and the corresponding second card slot 102 are perpendicular. When the slide base 1 is in the initial state, that is, in a state in which the arm pin is not pulled out, the first engagement groove 101 is opposed to the interlock lever 3. The second catch 102 is opposite the interlock lever 3 when the cylinder pin 9 is in the extended state.
In this embodiment, referring to fig. 3 and 4, in the state that the cylinder pin 9 is extended, when the cylinder pin 9 is retracted, the interlock lever 3 moves synchronously to the first position, at this time, the interlock lever 3 is snapped into the first clipping groove 101, at this time, if the displacement driving device 8 drives the sliding seat 1 to slide, the side wall of the first clipping groove 101 abuts against the interlock lever 3, the interlock lever 3 prevents the sliding seat 1 from sliding, so as to prevent the arm pin 7 from being pulled out, and the protection effect that the arm pin 7 cannot be pulled out when the cylinder pin 9 is retracted is achieved.
When the cylinder pin 9 extends, the interlock lever 3 moves synchronously to the second position, and at this time, the interlock lever 3 faces the second clamping groove 102, and at this time, if the displacement driving device 8 drives the sliding seat 1 to slide, the interlock lever 3 is clamped into the second clamping groove 102 while the sliding seat 1 slides. In this state, when the drive cylinder pin 9 is retracted, the interlock lever 3 abuts against the side wall of the second engagement groove 102, and the second engagement groove 102 prevents the interlock lever 3 from sliding, and further prevents the cylinder pin 9 from sliding and retracting, so that the protection effect of the cylinder pin 9 cannot be retracted after the arm pin 7 is pulled out is achieved.
Of course, the interlocking of the sliding seat 1 and the cylinder pin 9 is not limited to the manner of the first clamping groove 101 and the second clamping groove 102, for example, referring to fig. 5, in other embodiments provided by the present invention, the cylinder head seat 4 is provided with a guide hole 402, and the interlocking rod 3 passes through the guide hole 402 and is slidingly engaged with the guide hole 402. The interlock pole 3 is close to the one end of jar round pin 9 and is equipped with the direction inclined plane, and jar round pin 9 is equipped with the support inclined plane that laminates mutually with the direction inclined plane, and jar round pin 9 passes through support inclined plane drive interlock pole 3 and follows guiding hole 402 and slide, and sliding seat 1 is equipped with the joint hole 104 that supplies interlock pole 3 to stretch into. Specifically, the guide holes 402 are provided in a pair, and the pair of guide holes 402 are provided on both sides of the slide holder 1 and correspond one by one to the pair of interlocking bars 3, respectively. When the slide holder 1 is in the initial state, that is, in a state in which the arm pin is not pulled out, the guide hole 402 faces the engagement hole 104.
In this embodiment, referring to fig. 5, in a state in which the cylinder pin is extended, when the cylinder pin 9 is retracted, the cylinder pin 9 drives the interlock lever 3 to rise through the support slope, and the interlock lever 3 moves to the first position, at this time, the interlock lever 3 is engaged in the engagement hole 104. At this time, when the displacement driving device 8 drives the sliding seat 1 to slide, the interlocking rod 3 prevents the sliding seat 1 from sliding due to the abutting of the hole wall of the clamping hole 104 and the interlocking rod 3, so that the arm pin 7 is prevented from being pulled out, and the protection effect that the arm pin 7 cannot be pulled out when the cylinder pin 9 is retracted is realized.
When the cylinder pin 9 is extended, the interlocking lever 3 moves down along the supporting inclined surface, the interlocking lever 3 slides to the second position, at this time, the interlocking lever 3 is disengaged from the engagement hole 104, the interlocking lever 3 releases the restriction on the slide seat 1, and the slide seat 1 can slide. At this time, when the displacement driving device 8 drives the slide base 1 to slide, the guide hole 402 and the engagement hole 104 are shifted while the slide base 1 slides. In this state, when the cylinder pin 9 is driven to retract, the guide hole 402 is blocked at the bottom of the slide seat 1, the slide seat 1 prevents the interlock lever 3 from rising, and further the interlock lever 3 prevents the cylinder pin 9 from sliding and retracting, so that the protection effect of the cylinder pin 9 cannot be retracted after the arm pin 7 is pulled out is achieved.
