[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides an automatic loading and unloading device for cement poles, such as Figure 1-4 As shown, the automatic loading and unloading device for cement poles includes a base 1, a support base 2 and a clamping claw 12. The top of the base 1 is connected to the support base 2, and the top of the support base 2 is installed with a forward and reverse motor 6. The bottom end of the forward and reverse motor 6 is connected to a first screw rod 3, and the outer side of the first screw rod 3 is threadedly connected to a lifting block 5. A guide rod 4 is inserted into the inside of one side of the lifting block 5. A moving mechanism 7 is provided on one side of the lifting block 5, and a sleeve block 10 is provided on one side of the moving mechanism 7. A connecting arm 9 is inserted into the inner wall of the sleeve block 10, and a fixing mechanism 8 is provided on one side of the connecting arm 9. A servo motor 11 is installed at the bottom end of one side of the arm 9, and a second screw 13 is connected to one side of the servo motor 11, a coupling 14 is connected to one side of the second screw 13, and a third screw 15 is connected to one side of the coupling 14, and the outer side of the second screw 13 is threadedly connected to a clamp 12. The fixing mechanism 8 includes a hydraulic push rod 801, a limit cover 802, a fixed rod 803, a sliding sleeve 804, a sliding rod 805, a clamping plate 806 and a plug 807. The hydraulic push rod 801 is installed on one side of the sleeve block 10, and a clamping plate 806 is connected to one side of the hydraulic push rod 801.

[0023] The working principle of the automatic loading and unloading device for cement poles is as follows: the device is placed on a plane for support through a base 1, and an external power supply is connected for power supply. The forward and reverse motors 6 are started to drive the first screw 3 to rotate in the opposite direction, so that the lifting block 5 is engaged with the thread on the first screw 3 and drives the connecting arm 9 on the moving mechanism 7 to move downward along the surface of the guide rod 4. At the same time, the clamping jaws 12 gradually approach the placed cement pole as the connecting arm 9 moves downward. Then, the servo motor 11 is started to drive the second screw 13 to rotate forward, and the coupling 14 drives the third screw 15 to rotate synchronously. Then, the two sets of clamping jaws 12 are engaged with the threads on the second screw 13 and the third screw 15 in opposite directions of the threads and gradually approach the inner wall of the connecting arm 9 to move the cement pole. The pole is clamped, and the forward and reverse motor 6 is started to drive the first screw 3 to rotate forward, so that the lifting block 5 drives the claw 12 holding the cement pole on the connecting arm 9 to gradually move up through thread engagement until it stops at a height slightly higher than the height of the transportation device, thereby achieving the effect of automatic loading. Then the moving mechanism 7 is started to drive the connecting arm 9 to move left and right through the sleeve block 10, until the cement pole clamped by the claw 12 moves to the top of the transportation device and stops, and then the servo motor 11 is started to drive the second screw 13 and the third screw 15 to rotate in the opposite direction, so that the two sets of claws 12 are separated through thread engagement to loosen the clamped cement pole and place it on the transportation device, thereby achieving the effect of automatic unloading and reducing the manual operation of the staff.

[0024] It should be noted that since the connecting arm 9 on the existing automatic loading and unloading device for cement poles is generally fixed in the sleeve block 10 by bolts, the staff needs to manually take tools to operate when fixing or disassembling it. Therefore, in order to solve the problem that the connecting arm 9 on the existing automatic loading and unloading device for cement poles cannot be automatically fixed, this solution adds a fixing mechanism 8 to facilitate the quick fixing of the connecting arm 9 inside the sleeve block 10.

[0025] In a further embodiment, Figure 1 , Figure 2 and Figure 4 As shown, a plug post 807 is connected to the inner wall of the splint 806, both ends of one side of the splint 806 are connected to sliding rods 805, and a sliding sleeve 804 is sleeved on the outer side of the sliding rod 805, the internal thread on one side of the sliding rod 805 is connected to the fixed rod 803, and one side of the fixed rod 803 is connected to the limiting cover 802, the sliding sleeve 804 is connected to the sleeve block 10, the guide rod 4 and the support seat 2 are integrated into a structure, the splint 806 forms a sliding structure through the sliding rod 805 and the sliding sleeve 804, and an internal thread matching the external thread on the fixed rod 803 is provided on the inner wall of the sliding rod 805.

[0026] When the connecting arm 9 needs to be fixed in the sleeve block 10 to support the clamping jaw 12, the connecting arm 9 is inserted into the sleeve block 10 by moving it, and the right side wall of the sleeve block 10 is fit and stopped with the right inner wall of the sleeve block 10. Then, the piston of the hydraulic push rod 801 is started to extend to push the clamping plate 806 to approach and fit the left side wall of the connecting arm 9 to fix the connecting arm 9 inside the sleeve block 10. At the same time, the plug post 807 is inserted into the connecting arm 9 as the clamping plate 806 moves to fix it for a second time to prevent the connecting arm 9 from sliding off. Then, the sliding rod 805 slides along the inner wall of the sliding sleeve 804 for guidance as the clamping plate 806 moves, so as to ensure the stability of the clamping plate 806. The fixing rod 803 is inserted into the sliding rod 805 through the limit cover 802, and the sliding rod 805 is connected to the sliding rod 805 through threaded engagement and tightening, so that the limit cover 802 limits the sliding rod 805 to prevent the sliding rod 805 from completely sliding out of the sliding sleeve 804 and affecting the guiding effect.

[0027] In a further embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the moving mechanism 7 includes a moving seat 701, a moving block 702, a slider 703, a screw rod 704, a connecting seat 705 and a stepping motor 706. The moving seat 701 is connected to one side of the lifting block 5. A stepping motor 706 is installed on one side of the moving seat 701, and a screw rod 704 is connected to one side of the stepping motor 706. The outer side of the screw rod 704 is threadedly connected to the moving block 702, and both ends of the moving block 702 are connected to the slider 703. One side of the moving block 702 is connected to the connecting seat 705. The connecting seat 705 and the sleeve block 10 are integrated into a structure. The sliders 703 are symmetrically distributed at both ends of the moving block 702. The slider 703 passes through the moving seat 701 and is connected to the moving block 702. The end of the screw rod 704 away from the stepping motor 706 is connected to the bearing on the inner wall of the moving seat 701.

[0028] In this embodiment, when it is necessary to adjust the position of the cement pole clamped by the clamping jaws 12, the stepper motor 706 is started to drive the screw rod 704 to rotate forward or reversely, and then the moving block 702 is engaged with the thread on the forward or reverse rotating moving block 702 to drive the slider 703 to slide left and right along the inner wall of the moving seat 701, so that the slider 703 guides the moving block 702, and at the same time, the connecting seat 705 drives the connecting arm 9 in the sleeve block 10 to move left and right as the moving block 702 moves, thereby achieving the effect of moving and adjusting the position of the clamping jaw 12, which is convenient for driving the cement pole to adjust its position so that it can be moved to the top of the transportation device for easy unloading.
