Problems solved by technology
[0002] At present, the application of tunnel boring machines in tunnel engineering has been rapidly developed, but the shortcomings of the construction process are gradually exposed, the most prominent of which is dust pollution
High-concentration dust pollution not only causes great harm to the health of tunnel construction workers, but also reduces visibility, which blocks the view of construction workers and reduces construction efficiency.
At present, the fans used for dust removal in tunnels cannot be adjusted by telescopic adjustment. In this case, the construction personnel must use other equipment such as excavators to complete the movement of the fans and the adjustment of the suction port, which brings great difficulties to the use of the fans. big inconvenience

Embodiment Construction
[0014] The present invention will be further described below in conjunction with accompanying drawing.
[0015] Such as figure 1 As shown, a telescopic blower for a tunnel dust collector according to the present invention includes a suction blower 1 and a telescopic device 2; The traction frame 2-1, the air duct traction frame 2-1 is connected with the upper part of the suction air duct 1 end; the multi-section telescopic arm 2-4 telescopically makes the suction air duct 1 extend or shorten.
[0016] On the basis of the above structure, the present invention provides an embodiment of a suction duct 1, which is a corrugated expansion tube, also called a corrugated compensator, which can ensure effective expansion and contraction deformation. Of course, other suitable forms of expansion tubes can also be used.
[0017] Since the air suction cylinder 1 is relatively long, in order to prevent the air suction cylinder 1 from falling down when it is extended, except that the telesc...

The invention discloses a telescopic air duct for a tunnel dedusting machine. The telescopic air duct comprises a suction air duct and a telescopic device. The telescopic device comprises multiple sections of a telescopic arm. An air duct traction frame is arranged at the front end of the first section of the telescopic arm and connected with the upper portion of the end of the suction air duct. The multiple sections of the telescopic arm extend and retract to enable the suction air duct to extend or retract. The suction air duct of the telescopic air duct for the tunnel dedusting machine can extend and retract to adjust the length, in the construction process, when the position of the air duct needs to be adjusted, construction personnel can control the telescopic device to extend and retract so as to drive the suction air duct to extend and retract, and accordingly it is guaranteed that the air duct has the length suitable for dust removal operation; and therefore, operation personnel can adjust the suction air duct of the dedusting equipment without other auxiliary equipment, the flexibility of the equipment is improved, deducting efficiency is guaranteed, the dust concentration is reduced, and construction efficiency is guaranteed.
Description
technical field [0001] The invention relates to a tunnel dedusting device, in particular to a telescopic air cylinder for a tunnel dedusting machine. Background technique [0002] At present, the application of tunnel boring machines in tunnel engineering has been rapidly developed, but the shortcomings of the construction process are gradually exposed, among which dust pollution is more prominent. High-concentration dust pollution not only causes great harm to the health of tunnel construction workers, but also reduces visibility, which blocks the view of construction workers and reduces construction efficiency. At present, the fans used for dust removal in tunnels cannot be adjusted by telescopic adjustment. In this case, the construction personnel must use other equipment such as excavators to complete the movement of the fans and the adjustment of the suction port, which brings great difficulties to the use of the fans. Big inconvenience. Contents of the invention ...
