Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of blasting hole sealing, in particular to a blasting hole sealing device for blasting. BACKGROUND

[0002] Blasting is a technology that uses explosives to produce compression, loosening, destruction, throwing and killing effects in air, water, soil and rock medium or objects to achieve the intended purpose. When the explosive charge explodes in the soil and rock medium or structure, it causes compression, deformation, destruction, loosening and throwing of the soil and rock medium or structure, mainly used for earthwork engineering, and demolition of metal buildings and structures.

[0003] During the blasting operation, the blasting hole needs to be sealed. Sealing can prevent premature leakage of explosive gas, increase explosive pressure and improve breaking effect. The sealing material can block the splashing of gravel and reduce safety risks. It can also inhibit dust dispersion and improve the working environment. In the existing sealing method, the sealing material is soil, cement, etc., and precast parts are also used, i.e. using parts similar to lids to seal the blasting hole, and rubber airbags are also used for sealing, but the sealing parts used in this method are basically not recyclable. SUMMARY

[0004] To solve the above problems, the present application discloses a blasting hole sealing device for blasting, which comprises a screw rod, a rubber air tire ball is inserted on the screw rod, an upper clamping plate and a lower clamping plate are inserted on the screw rod, and the rubber air tire ball is located between the upper clamping plate and the lower clamping plate. By moving the upper clamping plate and the lower clamping plate towards each other, the deformed rubber air tire ball is clamped, so that the rubber air tire ball and the inner wall of the blasting hole are in close contact, i.e. the sealing is completed.

[0005] A nut is threadedly connected to the screw rod, and the nut is located above the upper clamping plate. When the nut and the screw rod rotate relative to each other, the nut can press the upper clamping plate, and the lower clamping plate is used to clamp the rubber air tire ball.

[0006] Preferably, the rubber air tire ball is an annular part, and the inside is filled with air. The hollow setting of the rubber air tire ball reduces the overall weight of the device and improves the deformation ability of the air under pressure.

[0007] Preferably, the upper end of the screw rod is provided with a regular hexagonal socket. A tool is used to clamp the regular hexagonal socket for rotating the screw rod.

[0008] Preferably, the lower end of the screw rod is fixedly connected with a supporting plate, and the lower clamping plate is arranged above the supporting plate. The supporting plate is arranged to support the lower clamping plate.

[0009] Preferably, the side wall of the nut is fixedly connected with a fixing rod, and the other end of the fixing rod is fixedly connected with a thimble.

[0010] The beneficial effects of the present application are as follows:

[0011] 1. The rubber tire ball is provided with upper and lower clamping plates, and is clamped and deformed by rotating the bolt nut, so as to be in close contact with the blasting hole after deformation, thereby achieving plugging, and the deformation capacity is suitable for a wide range of hole diameters.

[0012] 2. The thimble is provided, and the device is bound with a rope during use, which is convenient for collecting after blasting and reusing. BRIEF DESCRIPTION OF DRAWINGS
