Description

Technical Field

[0001] The invention relates to a cutting device, in particular to a suspended tunnel ice-accumulation and deicing device which can be attached to a smooth tunnel wall. Background Art

[0002] With the increase of railway and highway networks, the total length of tunnels has also increased dramatically. When the weather is cold, icicles are easily formed on the tunnel vaults, and the icicles hang in the air, posing a safety hazard. Due to the high height of the tunnel, when icicles fall, they will also generate a great impact force and cause serious damage. Tunnel deicing is an important task that must be considered in road network maintenance.

[0003] The existing deicing mainly relies on manual deicing. The maintenance worker holds a tunnel deicing pole with a knocking rod and a pull wire on the top of the deicing pole. The worker pulls the pull wire to control the knocking rod to perform deicing. Long-term manual work easily makes the worker tired, and the length of the pole cannot be adjusted, which is inconvenient to use and carry.

[0004] In order to reduce the labor intensity of manual deicing, a tunnel deicing device was invented. An ice melting mechanism was set at the top of a telescopic rod to melt the ice with hot water. Due to the large specific heat capacity of water, its value is about 4.2×10 3 J / (kg℃), melting ice into ice water consumes a lot of heat, and this heat can only be provided by a large-capacity power supply, which is difficult to guarantee at the construction site.

[0005] The above de-icing schemes allow ice to fall freely during the de-icing process, which may easily injure operators. The amount of electricity required in the de-icing process is huge, and it is difficult to meet the workload for a long time. In addition, the weight of the entire equipment needs to be borne by the operator during the entire operation, and long-term operation is bound to cause operator fatigue. Summary of the invention

The top climbing device can be adsorbed on the tunnel top arch to reduce the burden on the operator. The ice collector can collect the cleared crushed ice and discharge it through the ice outlet.

The ice collector 5 is a funnel structure, and the ice outlet 14 is obliquely arranged at the lower end of the ice collector 5. The angle between the ice outlet 14 and the vertical direction is 30-45°. The ice outlet 14 is connected to the telescopic rod 1 through the second fixing block 8. The ice collector 5 can collect the cleared ice cubes and safely guide them out through the ice outlet 14 to prevent the ice cubes from falling arbitrarily and accidentally injuring the operator.

[0026] See also Figure 1 The present invention adds a climbing device 6, which is connected to the free end of the crossbar 2 through a universal spring tube 9. The bottom of the climbing device 6 is connected to one end of the universal spring tube 9 through a spherical joint 10. The climbing device can be adsorbed on the surface of the tunnel vault 11 to reduce the burden on the operator. After the climbing device 6 is adsorbed and connected to the surface of the tunnel vault 11, the deicer 4 rotates and moves through the universal spring tube 9 and the spherical joint 10 to achieve the removal of icicles 12 at different locations. The schematic diagram of the structure of the universal spring tube 9 can be seen in Figure 7 .

The number of the suction cups 6-1 is at least two, which are bonded and fixed to the top of the airbag body 6-2, imitating the climbing function of the gecko's limbs, so that the climbing device 6 can be effectively adsorbed on the tunnel vault 11. The reinforcing rib 6-3 is heat-sealed and fixed to the middle position inside the airbag body 6-2. The strength of the climbing device is effectively increased so that the airbag body 6-2 will not be torn during use. The airbag body 6-2 is heat-sealed, and the inflation and deflation port 6-6 is bonded to the side of the airbag body 6-2. The air volume in the airbag body is increased or decreased according to actual use needs. The covering structure 6-5 is heat-sealed and fixed to the bottom of the airbag body 6-2. The hard bottom plate 6-4 is fixed between the airbag body 6-2 and the covering structure 6-5, thereby ensuring the stability of the hard bottom plate 6-4 and increasing the actual operability of the above-mentioned tunnel deicer.

The other end of the connecting buckle 5-3 is a locking ring that can rotate around a pin shaft, which is fixedly installed on the end of the second ice collector 5-2. The connecting buckle 5-3 connects the first ice collector 5-1 and the second ice collector 5-2 into one by its own locking function. When removing larger icicles 12, the connecting buckle 5-3 can be loosened to remove the ice collector 5-1 so as to better remove the icicles 12.
