The implementation principle of the tunnel operation platform for construction in the embodiment of the application is as follows: put into the tunnel with tunnel work platform in, the motor drive hydraulic pump rotates, the hydraulic pump is taken the hydraulic oil in the hydraulic tank out, carry to the multichannel valve in, the piston rod of each hydraulic cylinder of multichannel valve control stretches out and draws back, thereby control the flexible subassembly 22 of first flexible subassembly 21 and/or second and accomplish and stretch out and draw back, perhaps control the regulation of angle between first flexible subassembly 21 and the flexible subassembly 22 of second, perhaps adjust the angle between first sucking disc 211 and/or the second sucking disc 221, make telescopic machanism 2 better adsorb and support buckled plate 5.
When the height that the staff worked needs to be adjusted, the multi-way valve control crane 31 goes up and down to drive the subassembly 32 of standing and go up and down, adjust staff's height, make staff's operating height correspond the height and the position of the buckled plate 5 that needs to be fixed.
When the height and the position of a worker do not correspond to the position of the corrugated plate 5 needing to be fixed, the multi-way valve controls the rotating platform 4 to rotate, the angle of the tunnel operation platform is adjusted, and the position of the worker corresponds to the angle of the corrugated plate 5 needing to be fixed.
The tunnel operation platform can enable workers to work at a higher position in the tunnel, and the workers can change working positions at any time.
For example, the corrugated plate 5 is adsorbed, supported and fixed, a worker places the corrugated plate 5 on a support frame, when the corrugated plate 5 needs to be installed, the first telescopic assembly 21 is started, the first telescopic assembly 21 is telescopic and/or angle-adjusted according to the height, angle and position of the first corrugated plate 5, the angle of the first suction cup 211 is adjusted to a proper position, the first suction cup is enabled to adsorb and support the corrugated plate 5, when the first suction cup 211 touches the corrugated plate 5, the first telescopic assembly 21 stops acting, the lifting platform 3 is lifted, the worker is enabled to be in a proper position, and the worker fixedly connects the first corrugated plate 5 to the support frame by using locking pieces such as bolts; after installing second buckled plate 5 again and placing suitable position on the support frame, the staff carries out fixed connection with second buckled plate 5 and first buckled plate 5 again, and rethread telescopic machanism 2 adsorbs and supports second buckled plate 5, and the staff is with 5 fixed connection of first buckled plate on the support frame.
Or, the flexible subassembly of first flexible subassembly 21 and second 22 needs the simultaneous working in time, start the flexible subassembly of first flexible subassembly 21 and second 22, adsorb and the height and the position of two buckled plates 5 that support as required, stretch out and draw back and/or the angle modulation is carried out first flexible subassembly 21, stretch out and draw back the flexible subassembly 22 of second, carry out the angle modulation to first flexible subassembly 21 and the flexible subassembly 22 of second, carry out the angle modulation to first sucking disc 211 and second sucking disc 221, make the length and/or the angle of first flexible subassembly 21 and the flexible subassembly 22 of second correspond corresponding buckled plate 5, adsorb and support two buckled plates 5 respectively, work platform 3 works, make things convenient for the staff respectively with two buckled plate 5 fixed connection on the support frame.
The motor or the diesel engine is started to lift the lifting frame 31, so that the standing component 32 is driven to lift, after the lifting frame 31 is lifted to a proper height, the worker controls the lifting frame 31 to stop acting, if the position of the standing component 32 in the horizontal direction is far away from the corrugated plate 5 to be supported, the piston rod of the sixth hydraulic oil cylinder 323 in the standing component 32 extends out of the control flat plate 321 to slide in the direction far away from the bottom plate 322, the whole length of the standing component 32 is increased, and the distance between the standing component 32 and the corrugated plate 5 is shortened.
Depending on the actual situation, the first telescopic member 21 and the second telescopic member 22 may be operated simultaneously or separately.
For example, when the support frame is fixed on the inner wall of a tunnel, the support frame is placed on the inner wall of the tunnel, and the support frame needs to be fixed, the telescopic mechanism 2 firstly adsorbs and supports the support frame, when the position of the support frame is higher, the motor or the diesel engine is started to lift the lifting frame 31, so that the standing component 32 is driven to lift, after the lifting frame 31 is lifted to a proper height, the worker controls the lifting frame 31 to stop acting, and then the worker fixes the support frame at the position.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
