Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. It is to be understood that the described embodiments are merely exemplary of the utility model, and not restrictive of the full scope of the utility model. All other embodiments, which can be obtained by a person skilled in the art without inventive effort based on the embodiments of the present invention, are within the scope of the present invention.
As shown in fig. 1-2, the utility model is a device for cleaning the small aperture of a deep hole by using high-pressure air, which comprises a rubber locking air pressure cap 1, a high-pressure air pipe 2 and a tension limiting component; the rubber locking air pressure cap 1 is of a conical cap body structure, one end of the high-pressure air pipe 2 is inserted into the rubber locking air pressure cap 1 and is fixedly connected with the rubber locking air pressure cap 1, the high-pressure air pipe 2 preferably adopts a high-pressure steel air pipe, an air outlet 3 is arranged at the insertion end of the high-pressure air pipe 2, and the other end of the high-pressure air pipe is connected with an air compressor; the opening degree limiting assembly is sleeved on the inserting end of the high-pressure air pipe 2 and is fixedly connected with the rubber locking air pressure cap 1, and the opening degree limiting assembly can limit the maximum opening angle of the rubber locking air pressure cap 1.
The specific structure of the opening degree limiting assembly is as follows:
the spacing subassembly of opening degree is by slip lantern ring 4, a plurality of gag lever post 5 and a plurality of cap head support chassis 6 that open constitute, the slip lantern ring 4 suit is served at the insertion of high-pressure blast pipe 2, its outer wall equidistant encircles and sets up a plurality of gag lever posts 5 that open, the one end that opens gag lever post 5 is articulated with the outer wall of slip lantern ring 4, the other end is articulated with cap head support chassis 6, a plurality of cap head support chassis 6 use the circular cone summit of the conical cap body as the center, equidistant dispersion laminating is in the inner wall of rubber closure wind pressure cap 1, and with the inner wall fixed connection of rubber closure wind pressure cap 1. The number of the opening limiting rods 5 and the number of the cap head supporting frameworks 6 are at least two. After the air outlet 3 of the insertion end of the high-pressure air pipe 2 generates high-speed high-pressure gas, the rubber locking air pressure cap 1 deforms, when the rubber locking air pressure cap 1 is opened, the sliding sleeve ring 4 slides on the high-pressure air pipe 2, and the two sections of the opening limiting rod 5 are hinged with the sliding sleeve ring 4 and the cap head supporting framework 6 respectively, so that the maximum opening angle of the rubber locking air pressure cap 1 can be limited.
When the device for cleaning the small aperture of the deep hole by utilizing the high-pressure air is used for cleaning the small aperture of the deep hole, the cleaning can be carried out according to the following steps.
Inserting an insertion end of a high-pressure air pipe 2 into a grouting hole needing hole cleaning, and simultaneously connecting the other end of the high-pressure air pipe 2 with an air compressor to inject high-speed high-pressure air; injecting high-speed high-pressure gas to enable the rubber locking air pressure cap 1 connected to the insertion end of the high-pressure air pipe 2 to deform, opening the rubber locking air pressure cap 1 to be attached to the hole wall of the grouting hole, enabling the high-speed high-pressure gas to be turned by the inner wall of the cap head and discharged from the orifice direction of the grouting hole, and discharging accumulated slag in the grouting hole nearby the rubber locking air pressure cap 1 in the gas discharging process according to the gas discharging direction; and step three, pulling out the high-pressure air pipe 2 from the grouting hole at a constant speed, keeping the rubber locking air pressure cap 1 moving towards the orifice direction at a constant speed, keeping the accumulated slag of the inner hole blown out from the deep hole to be uniformly discharged towards the orifice, and finishing the hole cleaning work after the insertion end of the high-pressure air pipe 2 moves from the hole to the orifice.
It should be noted that, in the second step, there is a limiting effect of the opening degree limiting assembly, and after the high-speed high-pressure gas is injected, the opening degree limiting assembly can limit the maximum opening angle of the rubber locking air pressure cap 1.
