Detailed Description
The following describes the embodiments of the present invention further with reference to the drawings and technical schemes.
A cardboard tilting mechanism is proposed to the upset of cardboard, and specific implementation method is as follows:
the clamping plate overturning mechanism consists of five parts: the spring balancing device is used for saving the force of an operator during overturning; second, the guiding device 9 is used for guiding the movement track of the steel wire rope 7 and preventing the steel wire rope 7 from falling off; thirdly, a bidirectional pulley block 10 is used for determining a specific movement track of the steel wire rope 7 in the using process; fourthly, a clamping plate lock catch 11 is used for determining the hanging position of the clamping plate after overturning; fifth, a bracket 12 is provided for mounting the spring balance device to the main body frame. The specific structure is shown in fig. 3.
The spring balance device consists of a shell 1, a mounting seat 2, a coil spring 3, a cone pulley 4, an adjusting worm 5, a stop pin 6, a steel wire rope 7 and a lifting hook 8; the principle is that the operator is brought to a non-heavy or less-heavy state by the tension of the coil spring 3. The specific structure is shown in fig. 1 and 2.
The using method of the clamping plate overturning mechanism comprises the following steps:
(a) The device comprises a main body frame, a bracket 12, a mounting seat 2 of a spring balance device, a lifting hook 8, a clamping plate, a bidirectional pulley block 10, a steel wire rope 7, a guiding device 9, a clamping plate lock catch 11 and a clamping plate lock catch, wherein the bracket 12 is mounted on the main body frame, the mounting seat 2 of the spring balance device is mounted on the bracket 12, the clamping plate is connected with the lifting hook 8, the mounting position of the bidirectional pulley block 10 is determined according to the overturning route of the clamping plate, the steel wire rope 7 in the spring balance device is mounted on the bidirectional pulley block 10, the guiding device 9 is mounted on the mounting seat 2 after the steel wire rope 7 is mounted, and the position of the clamping plate after the clamping plate is hung is determined through overturning track simulation.
(b) And an adjusting worm 5 on the spring balance device is adjusted to enable the balance force of the spring balance device to reach a reasonable range. When adjusted clockwise, the counter weight increases, whereas the counter weight decreases. Along with the extension and shortening of the coil spring 3, the tension of the coil spring is continuously changed, and the spring balancing device balances the self weight of the operated object by utilizing the principle, so that the operated object is in a non-heavy or small-weight state.
(c) When the operator is taken out from the spring balance device, the stop pin 6 is pulled out by the pull rod, rotated clockwise by 30 degrees and put back into the clamping groove, and the operator is taken down after the cone pulley 4 is locked, so that the rapid recovery of the suddenly unloaded lifting hook 8 to hurt people and damage tools is prevented. A specific use case is shown in fig. 4.
The notes during use are as follows:
(a) When the spring balance device is disassembled, the worm 5 needs to be adjusted to rotate anticlockwise, so that other works can be performed when the coil spring 3 is in a loose state completely.
(b) The spring balance should be checked regularly.
(c) When the spring balance device is not used for a long time, the spring balance device needs to be unloaded and stored, and dampproof is noted so as to prevent the coil spring 3 from rusting.
Work efficiency calculation:
the length of the clamping plate is 1500mm, the weight G is 10.5Kg, namely 105N, the maximum tension adjusting range of the spring balancing device is 15-22Kg, and the maximum tension is selected to be 20Kg, namely 200N in the using process; the pulling force is linearly proportional to the length of the extended wire rope 7, and the maximum elongation of the wire rope 7 is 1500mm.

F 1 ·L 1 ＝G·L 2
F 1 ×1565＝105×720
F 1 ＝48.3N
when the angle is 90 degrees and the angle is,
F 2 ·L 1 ＝G·L 2

2. after the clamping plate overturning mechanism is used
When the angle is 45 degrees and the angle is,
F 1 ·L 1 +F bullet ·L Bullet ＝G·L 2
F’ 1 ＝12.8N
When the angle is 90 degrees and the angle is,
F 2 ·L 1 +F bullet ·L Bullet ＝G·L 2
F’ 2 ＝＝27.1N

F’ 2 to use the inventionAfter the clear clamping plate overturning structure, the force applied by an operator when the angle is 90 degrees;
F bullet Is the tension of the coil spring; l (L) Bullet Is the moment of the coil spring; g is the weight of the clamping plate.
Conclusion: through verification, the balance force of the spring balance device is 1.5-2 times of the weight of the clamping plate, and the action point of the spring balance device on the clamping plate is a proper position at 1/3 to 1/2 of the fixed end of the clamping plate.
It is concluded that the application of the card turnover mechanism of the invention can save the force of the operator by 1/2 to 2/3.
