Description

Hole plug inflating tank Technical Field The utility model relates to an inflation device of a well hole plug, in particular to an inflation tank of the well hole plug. Background The well plug is an important device for plugging a blasthole in underground blasting operation, and is in the form of a sealing bag, and the working performance of the well plug directly influences the blasting effect and safety. The existing well hole plug realizes the sealing of the blast hole mainly by inflating and expanding the well hole plug through an inflating tank, and the plugging mode is widely applied to mining and engineering blasting. The existing well hole plug working process is generally that a well hole plug device is firstly lowered to a preset depth along a gun hole, then a valve of an air charging tank is opened through a control device to enable compressed air to enter a sealing bag, and the sealing bag is gradually expanded under the action of air pressure until the sealing bag is tightly attached to the gun hole wall, so that effective blocking is formed. And then introducing the blasting device into the well to the expanded sealing bag, supporting the blasting device by the sealing bag to fix the point, and then blasting. However, existing wellbore plug gasifiers suffer from significant technical drawbacks. The main problem is that the control accuracy of the inflation process is insufficient. The current inflation control device often adopts a simple valve opening and closing mode, and an operator is difficult to accurately control the inflation speed. During the lowering of the wellbore plug downhole, if an operational failure occurs resulting in an excessive inflation rate, the bag will begin to expand before reaching the target location. This premature expansion can have serious consequences. Because of the limited space in the wellbore, once the bag is inflated at a non-target location, it is prone to jamming against the wellbore wall, preventing the wellbore plug from being lowered further to a predetermined depth. This not only affects the normal performance of the blasting operation, but may also lead to equipment damage or require additional work to deal with the sticking problem. Disclosure of utility model The utility model aims to provide a well hole plug inflating tank. The hole plug inflating tank is in a multistage inflating mode, so that the inflating tank is low in deflation speed under misoperation, the hole plug is prevented from being clamped above a designated position, and the hole plug cannot reach a blasting site. The technical aim of the utility model is realized by the following technical scheme: A well hole plug air filling tank comprises a tank body, wherein high-pressure air is filled in the tank body, an air outlet is formed in the top of the tank body, an air filling control device comprises a mounting seat, a support, a protection frame, two guide rails, a through groove, a sliding plate and a plurality of gears, wherein the mounting seat is in threaded connection with the tank body, the support is arranged on one side of the top of the mounting seat, the protection frame is fixedly connected to one side of the support, the two guide rails are arranged in the middle of the protection frame, the guide rails are connected with the protection frame and the support, the through groove penetrates through the support and the protection frame and is positioned between the two guide rails, the sliding plate is connected in the through groove in a sliding mode, the bottom of the sliding plate is made of rubber materials, and the top of the sliding plate is provided with the gears.
