Specifically, referring to fig. 1, 2 and 3, the link mechanism 32 includes a driving link 321 and a driven link 322, one end of the driving link 321 is rotatably connected to the robot arm 2, one end of the driven link 322 is rotatably connected to the robot arm 2, and a rotational connection position of the driven link 322 and the robot arm 2 is coaxial with the ratchet; a first link 323 is connected between the driving side link 321 and the driven side link 322.

When the driving side link 321 bears the torque which is increased instantly and has the counterclockwise direction, the pin shaft 3243 on the driving side link 321 enters the second groove 3242 from the first groove 3241; when the driving side link 321 is subjected to a moment-increasing clockwise torque, the pin 3243 of the driving side link 321 enters the first groove 3241 from the second groove 3242.
Specifically, in order to prevent the link mechanism 32 from being deformed due to impact on the link mechanism 32 when the torque borne by the driving side link 321 changes, the link mechanism 32 is further provided with a buffer assembly, and the buffer assembly includes a second link 325, a buffer 326 and a sleeve 327; the second link 325 is rotatably connected to the driven side link 322 at one end, and coaxially sleeved with a buffer 326 and a sleeve 327 at the other end, the sleeve 327 is rotatably connected to the driving side link 321.

In addition, the adjusting device further comprises a guide wheel 34 used for guiding the direction in the moving process of the traction rope 33, the guide wheel 34 is fixed on the surface of the mechanical arm 2, the traction rope 33 slides along a groove arranged on the guide wheel 34, and the guide wheel 34 can restrict the position of the traction rope 33, so that the traction rope 33 is basically parallel to the mechanical arm, and the traction rope 33 is prevented from interfering with other objects to influence the normal operation of the engineering machinery.
In addition, in order to prevent the ratchet wheel 311 from rotating reversely when the drum winds up the traction rope 33, the ratchet mechanism 31 is further provided with a check pawl 313 which prevents the ratchet wheel 311 from rotating reversely.
It is conceivable that the illumination lamp position adjusting device is not only suitable for the case where the mechanical arm 2 of the construction machine is disposed obliquely with respect to the horizontal plane, but also suitable for the case where the illumination lamp position adjusting device is disposed in actual life, for example, in a factory building with an inclined roof.
The working principle and the working condition of the thickness measuring device of the embodiment are as follows:
referring to fig. 1, the adjusting device is suitable for a case where a robot arm 2 of a construction machine is disposed to be inclined with respect to a horizontal plane.
Referring to fig. 2, in the initial state, the lamp 1 is located at the lowest position of the mechanical arm, the pin 3243 is located in the first groove of the L-shaped groove, and the driving pawl 312 is engaged with the ratchet wheel 311.
When the mechanical arm 2 of the construction machine needs to be illuminated at a position higher than the initial state, referring to fig. 2, the driving side link 321 is driven by the prime mover, at this time, the driving side link 321 swings counterclockwise around the rotational connection position of the driving side link 321 and the mechanical arm 2, the driving side link 321 drives the first link 323 to move, because the ratchet wheel 311 has resistance to the driving pawl 312, the driving pawl 312 and the driven side link 322 remain relatively stationary, the driving pawl 312 does not rotate around the rotational connection position of the driving pawl 312 and the first link 323, the driving pawl 312 does not rotate around the rotational connection position of the driving pawl 312 and the driven side link 322, and the driving side link 321, the driven side link 322, the first link 323 and the mechanical arm 2 may form a parallelogram mechanism. Therefore, the first connecting rod 323 drives the driven connecting rod 322 and the driving pawl 312 to rotate anticlockwise around the rotating connection position of the driven connecting rod 322 and the mechanical arm 2, the connecting rod mechanism 32 resets after the connecting rod mechanism 32 rotates clockwise, after the reciprocating motion for multiple times, the rotation of the ratchet wheel 311 drives the winding drum 30 fixed with the ratchet wheel to rotate continuously, the winding drum 30 winds the traction rope 33, the traction rope drives the illuminating lamp 1 to move along the mechanical arm 2, and the illuminating lamp 1 is pulled to a certain designated position at the high position of the mechanical arm 2. And the ratchet wheel 311 does not reverse due to the presence of the check pawl 313.
After the illumination is finished, referring to fig. 3 and 4, the prime mover connected to the driving side link 321 increases the output torque, so that the driving side link 321 moves counterclockwise with a larger force, at this time, the pin 3243 enters the second groove 3242 from the first groove 3241 of the "L" shaped groove, and the adjusting element 324 and the first link 323 generate an upward deviation, and the parallelogram mechanism fails. When the driving side link 321 rotates clockwise again, the adjusting element 324 is shifted upwards to drive the driving pawl 312 to move clockwise around the rotational connection between the driving pawl 312 and the driven side link 322, the driving pawl 312 is lifted, then the prime mover connected with the non-return pawl 313 drives the non-return pawl 313 to rotate clockwise, and the non-return pawl 313 loses the function of preventing the ratchet 311 from reversing. At this moment, because arm 2 sets up for the horizontal plane slope, light 1 slides down under the drive of gravity, and reel 30 release the haulage rope, and light 1 resets, relies on gravity to realize resetting of light 1, can realize energy-concerving and environment-protective.
It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. And are neither required nor exhaustive of all embodiments. And obvious changes and modifications can be made without departing from the scope of the invention.
