Technical Field
The utility model relates to an aerify the counter weight and connect, especially relate to an air spacer is with aerifing the counter weight and connecting.
Background
The air spacer mainly comprises three modes of pressing, lifting and pulling and inflating, and the three modes all adopt the structural principle that the air bag is formed in an inflating mode to extrude the wall of a blast hole. When the inflatable air spacer is used under the water hole condition, the material of the spacer can float up in the water and can not sink to the position with required interval, so the air charging connector of the inflatable air spacer is additionally provided with a counterweight. However, although the air interval period can sink along with the counterweight, when the air interval period reaches a specified position, the air spacer can float upwards, the orientation of the air spacer is not fixed downwards, positioning errors can occur, and difficulty is increased for forming an air bag to extrude the wall of the blast hole subsequently.
Disclosure of Invention
The utility model discloses to current air spacer with aerifing the technical problem that the counter weight joint can not help air spacer pinpoint, provide one kind and can help air spacer pinpoint the air spacer with aerifing the counter weight joint.
Therefore, the technical scheme of the utility model is that the air-assisted air separator comprises a balancing weight with an air passage in the middle, an upper interface of the air passage is provided with; the balancing weight overcoat is equipped with the movable sleeve, and the balancing weight is close to the position of lower extreme and is equipped with the boss of evagination, and the movable sleeve includes cavity sleeve, is connected and can hang the annular member on the boss with cavity sleeve upper port.
Preferably, after the air spacer is connected to the air nozzle joint, a part of the air spacer extends out of the hollow sleeve.
Preferably, the hole of loop forming element includes hole and lower hole down, and the internal diameter of hole is greater than the external diameter of boss down, and the internal diameter of going up the hole is greater than the external diameter of balancing weight and is less than the external diameter of boss.
Preferably, the inner diameter of the hollow sleeve is larger than the outer diameter of the air spacer.
Preferably, the inner diameter of the part of the hollow sleeve close to the lower port is gradually larger from top to bottom.
Preferably, the outer diameter of the upper end of the weight is smaller than the outer diameter of the lower end.
The beneficial effects of the utility model, simple structure, convenient operation hangs the movable sleeve on the balancing weight through the setting, makes air spacer orientation fixed downwards in the big gun hole, can not float on the surface of water, effectively avoids positioning error. The movable sleeve is slidably sleeved on the balancing weight, the air spacer expands to extrude the movable sleeve to move upwards, namely the movable sleeve cannot influence the normal use of the air spacer, and the air spacer can be ensured to face to the position in the water hole and be accurately positioned.

Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1-3, an air spacer is provided with an air-filled counterweight connector, which comprises a counterweight block 1 with an air passage 2 in the middle, an air pipe connector 3 for connecting with an air-filled pipe is arranged at the upper interface of the air passage 2, and an air nozzle connector 4 for connecting with an air nozzle of an air spacer 5 is arranged at the lower interface of the air passage 2; the outer cover of 1 balancing weight is equipped with movable sleeve 6, and balancing weight 1 is equipped with the boss 7 of evagination near the position of lower extreme, and movable sleeve 6 includes cavity sleeve 8, is connected and can hang annular member 9 on boss 7 with cavity sleeve 8 upper port.
After the air spacer 5 is attached to the air nozzle joint 4, a part of the air spacer 5 protrudes from the hollow sleeve 8.
The hole of loop forming element 9 includes hole 10 and hole 11 down, and the internal diameter of hole 11 is greater than the external diameter of boss 7 down, and the internal diameter of going up hole 10 is greater than the external diameter of balancing weight 1 and is less than the external diameter of boss 7.
The inner diameter of the hollow sleeve 8 is larger than the outer diameter of the air spacer 5.
The inner diameter of the part of the hollow sleeve 8 close to the lower port is gradually increased from top to bottom, and when the air spacer 5 expands, the contact surface with the hollow sleeve 8 is an inclined surface, so that the air spacer 5 is prevented from being damaged.
The external diameter of the upper end of the balancing weight 1 is smaller than that of the lower end, so that the balancing weight 1 can be conveniently inserted into the lower port of the movable sleeve 6 and then inserted out of the upper port of the movable sleeve 6. In this embodiment, the upper portion of the weight member 1 is tapered.
When the air nozzle is used, the lower end of the balancing weight 1 is connected with the air nozzle of the air spacer 5 through the air nozzle connector 4, the movable sleeve 6 is sleeved on the balancing weight 1, the movable sleeve 6 is hung on the boss 7 of the balancing weight 1 through the annular part 9, and the upper end of the balancing weight 1 is connected with the inflation tube through the air tube connector 3. The air spacer 5 is lowered to a designated position by a portable inflation tube, and the air spacer 5 sinks to the designated position along with the weight iron under the fixation of the movable sleeve 6. The direct flushing air spacer 5 is inflated, the part of the air spacer 5, which is positioned outside the movable sleeve 6, is firstly expanded, along with the increasing pressure in the bag, the air spacer 5 is gradually extruded from the movable sleeve 6, the movable sleeve 6 is gradually extruded to move upwards, finally, the residual air nozzle is in the movable sleeve 6, the air is continuously inflated until the pressure gauge shows that the pressure in the bag reaches a rated value, the inflation is stopped, and the air nozzle connector 4 is forcibly lifted upwards to separate the air nozzle.
The utility model discloses simple structure, convenient operation hangs the movable sleeve 6 on balancing weight 1 through the setting, makes air spacer 5 fixed downwards towards in the big gun hole, can not float on the surface of water, effectively avoids positioning error. The movable sleeve 6 is slidably sleeved on the balancing weight 4, the air spacer 5 expands to extrude the movable sleeve 6 to move upwards, namely the movable sleeve 6 cannot influence the normal use of the air spacer 5, and the air spacer 5 can be ensured to face to the position in the water hole and be accurately positioned.
However, the above embodiments are only examples of the present invention, and the scope of the present invention should not be limited thereby, and the replacement of the equivalent components or the equivalent changes and modifications made according to the protection scope of the present invention should be covered by the claims of the present invention.
