[0038] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.

[0039] The following Figures 1 to 2 will describe in detail the medium-thick plate support roll lifting pin device 10 provided in this embodiment.

[0040] Please refer to Figure 1 and Figure 2 , an embodiment of the present invention provides a medium-thick plate support roll lifting pin device 10 for loading a lifting pin 800 into a mounting pin hole 110. The medium-thick plate support roll lifting pin device 10 includes a support roll 100, a limit switch 210, a lifting pin support, a lifting frame 400, a moving platform 500, a pushing mechanism, and a clamping mechanism; the support roll 100 is provided with a mounting pin hole 110; the limit switch 210 is used to control the support roll 100 to stop when it moves to a preset position; the lifting pin support is arranged on one side of the preset position, and the lifting pin support is used to support the lifting pin 800 and can guide the lifting pin 800 in the Y direction; the lifting frame 400 is arranged in the Z direction and can be lifted; the moving platform 500 is movably arranged on the top of the lifting frame 400 in the X direction and can be adjusted; the clamping mechanism is movably arranged on the moving platform 500 in the Y direction, and the clamping mechanism is used to clamp the lifting pin 800 supported on the lifting pin support; the pushing mechanism is fixed on the moving platform 500, and the pushing mechanism is connected to the clamping mechanism. The pushing mechanism is used to push the clamping mechanism to move in the Y direction, so as to push the lifting pin 800 clamped by the clamping mechanism to be assembled with the mounting pin hole 110.

[0041] It should be noted that: taking the Figure 1 relative position for introduction, the "Z direction" refers to the direction indicated by the arrow Z in Figure 1 , and the two arrows Z represent the positive and negative directions of the Z direction. The "Y direction" refers to the direction indicated by the arrow Y in Figure 1 , and the two arrows Y represent the positive and negative directions of the Y direction. Taking the Figure 2 relative position for introduction, the "X direction" refers to the direction indicated by the arrow in Figure 2In the direction indicated by arrow X, the two arrows X refer to the positive and negative directions of the X direction.

[0042] The limit switch 210 includes an induction block. The induction block is set at a preset position. The induction block detects a position signal indicating that the support roller 100 has moved to the preset position. The limit switch 210 controls the support roller 100 to stop at the preset position according to this position signal. The limit switch 210 is installed on the lower side of the ground 900 and the lower side of the track 200. The induction block is installed on the auxiliary bracket 910. The mounting pin hole 110 moves along the track 200 with the support roller 100 and automatically stops when the positioning device of the support roller 100 touches the induction block. At this time, the center line of the mounting pin hole 110 coincides with the center line of the lifting pin 800. Specifically, the limit switch 210 is set at a position 3610 mm above the center line of the lifting pin support and 750 mm forward in the Y direction.

[0043] The lifting pin support is used to guide the lifting pin 800 to align with the mounting pin hole 110, and at the same time prevent potential safety hazards caused by the falling of the lifting pin 800 from a high altitude in case of power failure or malfunction of the pushing mechanism. Before installing the lifting pin 800, place the lifting pin 800 on the lifting pin support. During the process of the lifting pin 800 moving along the lifting pin support in the Y direction towards the mounting pin hole 110, the center line of the lifting pin 800 coincides with the center line of the mounting pin hole 110.

[0044] The moving platform 500 can be moved along the X direction by screw propulsion. The screw can be finely adjusted to ensure that the center line of the mounting pin hole 110 coincides with the center line of the lifting pin 800.

[0045] According to the stopping position of the support roller 100, that is, the preset position, adjust the lifting frame 400 along the Z direction and adjust the moving platform 500 along the X direction. After the adjustment is completed, fix it, and then place the lifting pin 800 on the lifting pin support. Push the clamping mechanism along the Y direction through the pushing mechanism and stop moving when it touches the lifting pin 800. Start the clamping function of the clamping mechanism to clamp the lifting pin 800. Operate the pushing mechanism to push the clamping mechanism along the Y direction to push the lifting pin 800 into the mounting pin hole 110. Stop operating the pushing mechanism to move along the Y direction after it is installed in place. Loosen the clamping mechanism and operate the pushing mechanism to pull the clamping mechanism back along the Y direction to complete the assembly. Among them, the process of taking out the lifting pin 800 is opposite to the operation steps of installing the lifting pin 800.

[0046] The whole process does not require manual participation, with high safety. At the same time, due to the function of the lifting pin support, the lifting pin 800 can be more smoothly inserted into the mounting pin hole 110, and the lifting pin 800 will not fall, which further improves the safety. The whole process is simple and fast, improving the installation efficiency.

[0047] Refer to Figure 1 and Figure 2, in this embodiment, the pushing mechanism is a hydraulic cylinder 600, and the hydraulic cylinder 600 includes a cylinder block and a piston rod assembled with the cylinder block; the cylinder block is arranged along the Y direction, and the piston rod is connected to the clamping mechanism; the piston rod is used to move along the Y direction during the process of moving relative to the cylinder block to push the clamping mechanism to move.

[0048] Using the hydraulic cylinder 600, the structure is simple, and it is easy to control during the process of driving and controlling the movement of the clamping mechanism, improving work efficiency; at the same time, the occupied space is reduced.

[0049] Refer to Figure 1 and Figure 2 , in this embodiment, the clamping mechanism includes a three-jaw chuck 700, the three-jaw chuck 700 is connected to the piston rod, and the three-jaw chuck 700 is used to clamp one end of the lifting pin 800 away from the mounting pin hole 110.

[0050] The three-jaw chuck 700 is a hydraulic three-jaw chuck 700, and the opening and closing of the three-jaw chuck 700 can be controlled by a button. Move the hydraulic three-jaw chuck 700 along the Y direction and stop moving when it touches the lifting pin 800, and start the clamping function of the hydraulic three-jaw chuck 700 to clamp the lifting pin 800. Operate the piston rod of the hydraulic cylinder 600 to push the three-jaw chuck 700 to move along the Y direction and push the lifting pin 800 into the mounting pin hole 110.

[0051] After the installation is in place, stop operating the piston rod of the hydraulic cylinder 600 to move along the Y direction. Loosen the hydraulic three-jaw chuck 700, operate the piston rod of the hydraulic cylinder 600 to move back along the Y direction, and complete the assembly. The process of taking out the lifting pin 800 is opposite to the operation steps of loading the lifting pin 800.

[0052] Refer to Figure 1 , in this embodiment, the pushing mechanism, the clamping mechanism, and the lifting pin support are arranged in sequence along the Y direction. A reasonable layout is achieved, and at the same time, the occupied space is reduced.

[0053] Refer to Figure 1 , in this embodiment, the lifting pin support is fixed on the moving platform 500. The lifting pin support is fixed on the moving platform 500, and relative to the lifting pin support arranged on the ground 900, the rigidity and strength of the lifting pin support can be improved. At the same time, the lifting pin support moves synchronously with the moving platform 500, enabling the lifting pin 800 on the lifting pin support to correspond to the mounting pin hole 110.

[0054] Refer to Figure 1 , in this embodiment, the lifting pin support includes a support rod 300, the support rod 300 is fixed on the moving platform 500 along the Y direction, and the support rod 300 is used to pass through the central hole of the lifting pin 800 and can guide the lifting pin 800 along the Y direction.

[0055] Before installation, the lifting pin 800 is threaded through the support rod 300. During installation, the clamping mechanism clamps the lifting pin 800 on the support rod 300, and under the pushing action of the pushing mechanism, the lifting pin 800 is pushed to move along the support rod 300 to be inserted into the installation pin hole 110.

[0056] Referring to Figure 1 , in this embodiment, the support rod 300 is arranged at an angle to the horizontal plane. The support rod 300 is used to make the lifting pin 800 have a tendency to move away from the installation pin hole 110, so as to prevent the lifting pin 800 from sliding out of the support rod 300.

[0057] Taking Figure 1 the relative position in as an example, due to the action of gravity, the lifting pin 800 has a tendency to lean to the left, which can prevent the lifting pin 800 from sliding to the right. It has a protective effect after the three-jaw chuck 700 gets out of control and can prevent the lifting pin 800 from falling and hurting people.

[0058] In this embodiment, the angle range between the support rod 300 and the horizontal plane is 0.8° - 1.2°.

[0059] Taking Figure 1 the relative position in as an example, the angle between the support rod 300 and the horizontal plane can also be regarded as the angle between the center line of the lifting pin support and the center line of the support roller 100, and the angle value is 1 degree. Specifically, within the range of the length D of the lifting pin 800 being 200mm - 600mm, the value of the lifting pin support 14d is calculated by the formula: d = 0.75D.

[0060] Referring to Figure 1 , in this embodiment, the lifting pin support further includes a fixing rod 310. The fixing rod 310 is fixed on the moving platform 500 along the Z direction, and one end of the support rod 300 away from the installation pin hole 110 is fixed to the fixing rod 310. Specifically, the fixing rod 310 and the support rod 300 form an "L" - shaped structure.

[0061] According to a medium - thick plate support roller lifting pin device 10 provided by this embodiment, the working principle of the medium - thick plate support roller lifting pin device 10 is as follows: under the support and guiding action of the lifting pin support, the center line of the lifting pin 800 corresponds to the installation pin hole 110, and the lifting pin 800 is inserted into or taken out from the installation pin hole 110 under the pushing of the pushing mechanism and the clamping mechanism.

[0062] A medium - thick plate support roller lifting pin device 10 provided by this embodiment has at least the following advantages:

[0063] The driving mechanism drives the clamping mechanism to move along the Y direction, driving the lifting pin 800 to move along the guiding direction supported by the lifting pin, that is, the Y direction, until the lifting pin 800 is inserted into the mounting pin hole 110, completing the assembly of the lifting pin 800 and the mounting pin hole 110. The whole process does not require manual participation and has high safety. At the same time, due to the support of the lifting pin, the lifting pin 800 can be inserted into the mounting pin hole 110 more smoothly, and the lifting pin 800 will not fall off, which further improves the safety. The whole operation is simple and fast, improving the installation efficiency.

[0064] An embodiment of the present invention also provides a method for lifting and installing the support roll of medium - thick plate, which is used to implement the medium - thick plate support roll lifting and installing device 10. The method for lifting and installing the support roll of medium - thick plate includes: debugging the lifting frame 400 along the Z direction; debugging the moving platform 500 along the X direction; stopping the support roll 100 at a preset position through the limit switch 210; driving the clamping mechanism that clamps the lifting pin 800 on the lifting pin support to move along the Y direction through the driving mechanism until the lifting pin 800 is inserted into the mounting pin hole 110. It can improve the problems of unsafe and low - efficiency installation of the lifting pin 800.

[0065] According to the stopping position of the support roll 100, that is, the preset position, debug the lifting frame 400 along the Z direction and the moving platform 500 along the X direction. After debugging, fix them. Then place the lifting pin 800 on the lifting pin support, and the clamping mechanism clamps the end of the lifting pin 800 far from the mounting pin hole 110. At this time, start the driving mechanism. The driving mechanism drives the clamping mechanism to move along the Y direction, driving the lifting pin 800 to move along the guiding direction supported by the lifting pin, that is, the Y direction, until the lifting pin 800 is inserted into the mounting pin hole 110, completing the assembly of the lifting pin 800 and the mounting pin hole 110.

[0066] The control cabinet in this case and the external control cabinet jointly control the entire installation of the lifting pin 800 and the forward movement of the support roll 100. The control circuit is a star - delta step - down positive - reverse jogging and star - delta step - down positive - reverse continuous operation control circuit.

[0067] To ensure operation safety, when the device in this case needs to install the lifting pin 800, circuit switching is required. The control of the support roll is converted from being controlled by the external control cabinet to being controlled by the control cabinet in this case. The implementation method is to connect two sets of control lines in parallel to the main line and install a line conversion switch.

[0068] The control principle of the control cabinet in this case is as follows: 1. Press the jog start button SB32, the coil KM32 is energized and attracted, the motor rotates to push the traction cart to move forward. When it moves to touch the limit switch 210, the limit switch 210 is in the normally closed state. When it is energized, the coil KM32 is cut off and the motor stops moving. 2. After operating the hydraulic three-jaw chuck 700 clamping button, operate the hydraulic cylinder 600 forward push button. After pushing to the specified position, operate the hydraulic chuck release button and then operate the hydraulic cylinder 600 rearward movement button. 3. After the assembly is completed, press the limit switch 210 short-circuit button. Continue to operate the traction cart to move to the specified area. The operation is completed.

[0069] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
