Simultaneously, be provided with in second installation arm 22 and drive mounting panel 23 for second installation arm 22 pivoted rotation driving piece (not shown in the figure), the rotation driving piece can select for use motor etc. to drive mounting panel 23 and rotate around the axis of second installation arm 22, thereby the drive is installed and is snatched subassembly 24 rotation on mounting panel 23, snatchs the direction of subassembly 24 self with the regulation, thereby be convenient for snatch the work to the buckled plate that each direction was placed.

In order to increase the rotation angle of the second mounting arm 22 to meet the requirement of wide-range angle adjustment, an auxiliary plate 27 is fixedly connected to one side of the first mounting arm 21 where the second cylinder 26 is mounted, a first arm 28 is hinged to the auxiliary plate 27, a second arm 29 is hinged to one end of the first arm 28 away from the auxiliary plate 27, and one end of the second arm 29 away from the first arm 28 is hinged to a side wall of the second mounting arm 22, so that a movable quadrilateral structure is formed among the first arm 28, the second arm 29, the first mounting arm 21 and the second mounting arm 22. One end of the second cylinder 26 is hinged to the auxiliary plate 27 and located on one side of the first arm 28, which is far away from the first mounting arm 21, of the first arm 28, the other end of the second cylinder 26 is hinged to the hinged shafts of the first arm 28 and the second arm 29, so that when the second cylinder 26 extends and retracts, every two adjacent edges of the quadrilateral structure can be driven to rotate relatively through the hinged shafts of the first arm 28 and the second arm 29, an included angle between the first mounting arm 21 and the second mounting arm 22 can be changed, and the arrangement of the first arm 28 and the second arm 29 can also increase the activity space of the second mounting arm 22, so that the rotation angle of the second mounting arm 22 is larger, and the application range is wider.

Referring to fig. 2, the mounting panel 23 is whole to be the triangular prism form, and one side and the second installation arm 22 of mounting panel 23 rotate to be connected, snatchs the subassembly 24 and is provided with two sets ofly, and two sets of subassemblies 24 that snatch set up respectively in mounting panel 23 not with the both sides that the second installation arm 22 is connected to the realization can snatch two buckled plates simultaneously through a manipulator 2, and work efficiency is higher.

The grabbing component 24 comprises a fixing frame 241 fixedly connected to the mounting plate 23, and the whole fixing frame 241 is in a groined shape and comprises a plurality of cross rods and a plurality of longitudinal rods which are connected. All articulated at mount 241 both ends have and snatch claw 242, it is circular-arc and two openings that snatch claw 242 set up relatively to snatch claw 242 cross-section, two openings that snatch claw 242 and mount 241 between form the accommodation space 244 that supplies the buckled plate embedding, one side rigid coupling that keeps away from accommodation space 244 at mount 241 simultaneously has and drives two respectively and snatch claw 242 around the articulated shaft pivoted third cylinder 243 with mount 241, third cylinder 243 is located between mount 241 and the mounting panel 23, and the third cylinder 243 both ends articulate with snatching claw 242 and mount 241 respectively. When the corrugated plate grabbing device is used, the two third air cylinders 243 are directly operated to retract, so that the two grabbing claws 242 can be respectively driven to rotate around the hinged shaft of the fixed frame 241 in the direction away from the accommodating space 244, and the corrugated plate can be smoothly placed in the accommodating space; after the corrugated plate is placed, the two third cylinders 243 are directly operated to extend out, so that the two grabbing claws 242 can be driven to rotate around the direction close to the accommodating space 244 in the axial direction of the hinge of the fixing frame 241, the positions of the corrugated plates in the accommodating space 244 are fixed through the two grabbing claws 242, and grabbing of the corrugated plates is achieved. Then, the corrugated plates in the accommodating space 244 can be conveyed to the position of the tunnel wall where the corrugated plates are to be installed through the first telescopic arm 11. Then through support tight device 3 with the buckled plate butt on the tunnel wall, the staff of being convenient for carries out fixed work to the buckled plate.

Referring to fig. 1 and 3, the abutting device 3 includes an abutting plate 31 hinged to the end of the second telescopic arm 12, an abutting block 32 fixedly connected to the abutting plate 31, and a fourth cylinder 33 driving the abutting plate 31 to rotate around a hinge shaft with the second telescopic arm 12, and both ends of the fourth cylinder 33 are hinged to the side wall of the second telescopic arm 12 and the abutting plate 31, respectively. In use, the abutment blocks 32 will abut directly against the corrugated plate thereby clamping the corrugated plate between the abutment blocks 32 and the tunnel wall. Can drive butt joint board 31 through fourth cylinder 33 around the articulated shaft rotation with the flexible arm 12 of second to adapt to the installation angle of buckled plate, make butt piece 32 can the butt on the buckled plate.

Wherein, support tight piece 32 and can be provided with a plurality ofly along the length interval of butt joint plate 31 to increase the contact point of supporting tight piece 32 and buckled plate, guarantee the installation stability of buckled plate, this application explains as the example with supporting tight piece 32 and setting up two.

The protection pad 34 is fixedly connected to one side of each abutting block 32, which is far away from the abutting plate 31, and the protection pad 34 can protect the corrugated plate, so that the corrugated plate is prevented from being damaged due to overlarge abutting force applied to the corrugated plate. Wherein, the protection is filled up 34 and is provided with a plurality ofly, and one side that a plurality of protection fills up 34 and keep away from to tight piece 32 is circular-arc and the ripple radian phase-match of its circular arc radian and buckled plate for when the protection fills up 34 butt on the buckled plate, the buckled plate is by the more firm of butt, and the buckled plate is also difficult from the protection fill up between 34 and the tunnel wall roll-off. Of course, when the length of the abutment block 32 is longer, the side of the guard pad 34 remote from the abutment block 32 will be corrugated to match the curvature of the corrugated plate. When the buckled plate through support tight device 3 butt on the tunnel wall, the staff just can stand on operation platform 4, fixes the buckled plate on the tunnel wall through the bolt to the realization is fixed to the installation of buckled plate.
