The disassembly and assembly device 8 is hoisted under the telescopic arm 6.

[0021] In this device, the control arm can achieve multi-directional adjustment so that the disassembly and assembly device 8 can accurately reach the side guard plate.

[0022] The disassembly and assembly device 8 is composed of clamping arms 801, connecting arms 803, a clamping device 802, a buffer device 804, a falling prevention device. Two clamping arms 801 and two connecting arms 803 form a square frame. Four lifting lugs 807 are provided on the upper side of the clamping arm 801. The disassembly and assembly device 8 is hoisted on the lower side of the control arm through the lifting lugs 807. A clamping device 802 is provided at one end of the clamping arm 801. Therefore, in order to ensure that each side of the frame is equipped with two clamping devices, an additional clamping arm 801 is provided on the outer side of each of the two clamping arms 801. A clamping oil cylinder 806 is provided inside the clamping arm 801. The front end of the clamping oil cylinder 806 is connected to the clamping device 802. The clamping device controlled by the clamping oil cylinder 806 can extend at the end of the clamping arm 801. An electromagnet 805 is provided inside the clamping device 802; a number of buffer devices 804 are provided on the lower side of the clamping arm 801. A spring 815 and an electromagnet 805 are provided inside the buffer device 804. The electromagnet 805 can adsorb the side guard plate; the falling prevention device is installed on the clamping device 802 and can prevent the side guard plate from falling off the clamping device 802.

[0023] The buffer device 804 is arranged on the lower side of the clamping arm 801 near the clamping device 802. The buffer device 804 is composed of a top plate 814, a bottom plate 813, an electromagnet 805, and a spring 815. The spring 815 is arranged between the top plate 814 and the bottom plate 813. The electromagnet 805 is installed on the floor 813. The top plate 814 is fixedly connected to the lower side of the clamping arm 801. The buffer device 804 can play a certain buffering role when clamping the side guard plate, avoiding hard contact between the entire device and the side guard plate.

[0024] The falling prevention device is composed of a connecting plate 805, a baffle 808, a driving oil cylinder 816, and a blocking rod 812. The upper side of the connecting plate 805 is connected to the clamping device 802. The baffle 808 is located inside the lower end of the connecting plate 805. A long rod 809 and a rotating plate 810 are provided at the lower part of the outer side of the connecting plate 805. Both ends of the long rod 809 are hinged to a rotating plate 810 respectively. A rotating shaft 811 is provided at the lower end of the rotating plate 810. The rotating shaft 811 passes through the connecting plate 805 and the baffle 808 and is fixedly connected to the blocking rod 812 inside the baffle 808. The rotating shaft 811 can rotate on the connecting plate 805 and the baffle 808; the rear end of the driving oil cylinder 816 is fixed on the connecting plate 805, and the front end of the driving oil cylinder 816 is hinged to the connecting seat on the lower side of the long rod 809.

[0025] After the clamping device 802 moves to the side of the side guard plate, the side guard plate will be adsorbed by the electromagnet 805 on the clamping device 802 and the buffer device 804. The width of the bottom plate 813 on the buffer device 804 is greater than the width of the baffle 808. At this time, the baffle 808 on the anti-falling device will support on the lower side of the side guard plate. The width of the baffle 808 is greater than the thickness of the side guard plate. Therefore, by using the driving oil cylinder 816 to control the rod 812 to rotate to the vertical direction, the side guard plate can be restricted to prevent it from falling off the clamping device 802.

[0026] The working process of this device is as follows:

[0027] When disassembling the side guard plate, the clamping oil cylinder 806 drives the clamping device 802 to be close to the side guard plate. The electromagnet 805 is powered on to make the electromagnet 805 adsorb the upper side guard plate. The clamping oil cylinder 806 drives the clamping device 802 to open, so that the side guard plate is separated from the top beam. Then the driving oil cylinder 816 is started to drive the rod 812 to rotate to the vertical direction. The anti-falling device blocks the side guard plate to prevent it from falling. Then the rotary arm oil cylinder 9 drives the rotary arm 3, and the boom oil cylinder 10 drives the boom 5 to move the side guard plate to the specified position. The driving oil cylinder 816 is started to rotate the rod 812 to the horizontal position. The anti-falling device loses its effect. The electromagnet 805 is powered off, and the side guard plate is removed.

[0028] When installing the side guard plate, place the side guard plate on the clamping device 802. The electromagnet 805 on the clamping device 802 is powered on to fix the side guard plate on the clamping device 802. The driving oil cylinder 816 is started to drive the rod 812 to rotate to the vertical direction. The anti-falling device blocks the side guard plate to prevent it from falling. Then the rotary arm oil cylinder 9 drives the rotary arm 3, and the boom oil cylinder 10 drives the boom 5 to move the side guard plate to the side guard plate installation position. Finally, the clamping oil cylinder 806 drives the clamping device 802 to install the side guard plate. After installing to a certain extent, the driving oil cylinder 816 is started to rotate the rod 812 to the horizontal position. The anti-falling device loses its effect. Then the clamping oil cylinder 806 drives the clamping device 802 to be installed in place. The electromagnet 805 is powered off to complete the installation.

For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
