[0001] The utility model relates to the technical field of static blasting devices, in particular to a static blasting hole enlarging temporary fixing device. Background Art

[0002] Static blasting mainly uses the expansion pressure of static crushing agents to crush hard media such as rocks and concrete. Static crushing agents are an inorganic compound with calcium oxide as the main component. When mixed with water, they will undergo a chemical reaction, resulting in volume expansion. The expansion pressure can reach 30-50MPa. This expansion pressure acts on the inside of the crushed object, causing cracks to form and gradually expand, ultimately achieving the purpose of crushing.

By setting up the support rod 210, several points are provided to facilitate the force balance around the blasting fixed barrel 100.

[0024] Example 2: Figure 1 and 2 The inner wall of the blasting expansion area 110 is used to hold the breaker, the support rod 210 is set to a cylindrical shape, the outer wall of the top of the adjusting rod 220 is welded with a sliding sleeve 221, and the inner wall of the sliding sleeve 221 is fixedly installed with an anti-slip sleeve. The inner wall of the sliding sleeve 221 is slidably connected with the outer wall of the support rod 210, and the bottom end of the sleeve 230 is welded with a base.

[0025] The specific usage scenario of this embodiment is: by setting up the blasting expansion area 110 to facilitate the operator to store the crushing agent, by compressing or pulling the telescopic joint, the blasting expansion area 110 can be overlapped, thereby achieving the effect of adjusting the height of the blasting expansion area 110.

[0026] The specific usage scenario of this embodiment is: by setting up the blasting expansion area 110 for holding the breaker, it is convenient for the breaker to effectively utilize the easy-to-break effect at the telescopic joint during expansion blasting, thereby facilitating the improvement of the utilization rate of the breaker, and by setting the sliding sleeve 221 to cooperate with the support rod 210 for sliding connection, it is convenient for the blasting fixed tube 100 to be supported by the adjusting rod 220 and the sleeve 230, thereby supporting the bottom end of the blasting fixed tube 100, and facilitating the reasonable adjustment of the support point of the sleeve 230 according to the terrain conditions around the blasting hole, thereby improving the stability of the installation of the blasting fixed tube 100 and facilitating flexible use.

[0027] Example 3: Figure 1 and Figure 2 The outer wall of one side of the adjusting rod 220 is evenly provided with teeth 222, and the inner wall of the sleeve 230 is provided with a sliding hole 231. The outer wall of the sleeve 230 is fixedly connected to the gear warehouse 240, and the inner wall of the gear warehouse 240 is rotated and connected to the gear 250 through an axle pin. The gear 250 is engaged with the teeth 222 for transmission connection, and the inner wall of the sleeve 230 is provided with a tooth groove 232. The tooth groove 232 is used to slide and position the teeth 222. The outer wall of the tooth groove 232 is plugged into the end cover plate 250, and the outer wall of the axle pin is fixedly connected to the crank 260. The crank 260 is used to rotate the gear 250 to control the adjusting rod 220 to adjust the height.

[0028] The specific use scenario of this embodiment is: by setting the teeth 222 and the gear 250 to engage with the transmission connection, it is convenient to make it possible to control the rotation of the gear 250, so as to drive the teeth 222 to complete the lifting and height adjustment inside the casing 230, thereby making it possible to lift and adjust the height inside the adjusting rod 220 and the casing 230, so that the blasting fixed tube 100 can freely adjust the height inside the blasting hole, and facilitate the precise fitting of the blasting agent used for static blasting with the blasting position, thereby maximizing the blasting accuracy and the utilization rate of the blasting agent, saving costs, improving the economy of equipment use, and improving In order to improve the efficiency of blasting, the handheld crank 260 is used to control the rotating gear 250, so that the gear 250 pushes the adjusting rod 220 to move up and down inside the casing 230 to adjust the height under the action of meshing transmission with the teeth 222, thereby facilitating the control of the height of the blasting fixed tube 100. By setting a plurality of independently adjustable height adjusting rods 220 and casings 230, it is convenient to control the different heights of the adjusting rods 220 and casings 230 when the ground around the blasting hole is uneven, so that the blasting fixed tube 100 and the blasting expansion area 110 remain stable, thereby improving the stability of the equipment operation.

[0029] The working principle of the present invention is as follows: when in use, a person skilled in the art adjusts the length of the blasting expansion zone 110 by pressing the telescopic joint at the blasting expansion zone 110, so that the blasting expansion zone 110 is located in the blasting position area, and then places the breaker for static blasting inside the blasting expansion zone 110, and then cooperates with the support rod 210 and the annular support frame 200 to be fixedly connected, which plays a supporting role on the top of the blasting fixed tube 100, and lowers the blasting fixed tube 100 into the blasting hole, so that the blasting expansion zone 110 is located at the position to be blasted in the blasting hole, and the blasting hole is fixed temporarily around to avoid the blasting slag blocking the blasting position and affecting the blasting effect, thereby improving the accuracy of static blasting, and adjusting the position of the sliding sleeve 221 on the outer wall of the support rod 210, and then controlling the rotating gear 250 by the hand-held crank 260, so that the gear 250 is pushed under the action of meshing transmission with the teeth 222. The dynamic adjustment rod 220 is raised and lowered inside the casing 230 to adjust the height, thereby facilitating the control and adjustment of the height of the blasting fixed tube 100. By setting a plurality of independently adjustable height adjustment rods 220 and casings 230, it is convenient to control the different heights of the adjustment rods 220 and casings 230 when the ground around the blasting hole is uneven, so that the blasting fixed tube 100 and the blasting expansion area 110 remain stable, thereby improving the stability of the equipment operation. Subsequently, water is added to the breaker in the blasting expansion area 110, so that the water and the breaker react chemically, so that the breaker can quickly squeeze the blasting expansion area 110 after expansion, so that the blasting expansion area 110 is quickly blasted and forms a large expansion force on the inner wall of the blasting hole, causing the inside of the blasting hole to collapse, thereby achieving rapid static blasting, improving work efficiency and blasting accuracy, and improving the practicality of equipment use.
