In the specific implementation process, the baffle 7 consists of door frames positioned at two ends of the winding drum 10 and two connecting rods 5 in the middle, and is made of round steel to ensure enough strength. The gantry should be on a vertical plane with the end of the drum 10, the upper semicircle should be concentric with the drum 10, and the distance between the two should be smaller than the diameter of the pulling rope 4, to prevent the pulling rope 4 from jumping out of the gap. The installation height of the connecting rod 5 needs to consider the rope outlet angle of the traction rope 4 so as to prevent the connecting rod from interfering with the traction rope 4;
by applying the baffle 7, the problem that the traction rope 4 is separated from the winding drum 10 due to over loosening, rope groove shallowing and the like can be avoided from all directions, and the driving shaft and the cam connecting shaft are protected from being damaged.
The stroke protector 8 is mounted between the flaps 7 at the exit spool 10 of the pull-cord 4. A section perpendicular to the traction rope 4 is chosen close to the position where the traction rope 4 exits the drum 10, where the motion trajectory of the traction rope 4 is a straight line. The traction rope 4 corresponds to the upper and lower end points of the receiving plate at the moving end point of the track, so that the left and right end points of the traction rope 4 entering and exiting the winding drum 10 are used as the limit positions of the end point limiting device, and the end point control of the up-and-down movement of the receiving plate is realized.
The working principle of the device is that when the receiving plate ascends and descends in the using process, the winding directions of the traction ropes 4 (using but not limited to steel wire ropes) on the winding drum 10 are leftward and rightward respectively; when the hauling rope 4 moves to the left limit position, the swing arm is pushed to move, so that the limit switch is triggered, the material receiving plate reaches the upper limit position, the limit switch is connected with the master control device, after the travel switch on the left side is triggered, the driving mechanism 6 stops running and gives an alarm, and after the alarm is given, the first swing arm 83 is reset through the elastic resetting piece 81, wherein the air spring is used but not limited; in a similar way, when the material receiving plate moves downwards, the traction rope 4 moves rightwards, and the swing arm is reset under the pushing of the air spring. When the hauling rope 4 moves to the right limit position, the travel switch on the right side is triggered, the material receiving plate reaches the lower limit position, and the operation is stopped.
In the using process, the weight measuring mechanism 1 uses but is not limited to a pin-type force measuring sensor, the pin-type force measuring sensor is arranged at the fixed end of the traction rope 4 and is connected with a master control device, the pulling force applied to the traction rope 4 can be monitored in real time, and when the pulling force applied to the traction rope 4 is larger than a certain set value A, the motor stops running. The set value a should be greater than the rated load of the traction rope 4 when the mechanism is in operation, but not more than 60% of the maximum breaking force of the traction rope 4.
Still be equipped with the grab bucket and open the chain protection mechanism of fighting: when the material receiving plate is at the lower limit position, if the material is accumulated on the material receiving plate, the tension of the traction rope 4 is greater than a certain set value B, and the grab bucket is not allowed to be opened for discharging. The set value B is the rated load of the traction rope 4 under the normal working condition.
A stroke end point protection mechanism is also arranged: the limit position of the material receiving plate running up and down is set by means of a cam limit mechanism 9 (an encoder is used but not limited in the application), wherein the upper limit position ensures that a certain safety distance is reserved between the material receiving plate and the upright post 3, and the interference between the material receiving plate and the upright post is avoided when an accident occurs.
There is also a mechanism run time limit: the material receiving plate is in a normal working condition, and the travel time of the material receiving plate in up-down operation is fixed. And if the running time of the mechanism exceeds the set time, stopping the running of the motor by 0.
The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
