[0002] Blasting is an engineering technique that uses the energy generated by the explosion of explosives to break up hard materials such as rocks and soil. Blasting is widely used in mining, tunnel construction, and building demolition.

[0003] Driven by technological advancements, modern blasting operations can now utilize not only explosives but also pre-splitting tools like hydraulic splitting rods. However, when using hydraulic splitting rods for pre-splitting rocks, hydraulic oil needs to be injected into the rod. Traditional hydraulic splitting rods lack a proper hydraulic oil filtration system, making the injected oil prone to impurities. This impurities can cause abrasive damage to the surfaces of precision parts such as the hydraulic pump and valve core, affecting the rod's lifespan and resulting in poor performance. Utility Model Content

[0004] The purpose of this utility model is to provide an auxiliary tool for rock pre-splitting in blasting operations. The hydraulic splitting rod does not have a complete hydraulic oil filtration mechanism inside, which easily leads to impurities in the hydraulic oil injected into the hydraulic splitting rod, thereby causing abrasive damage to the surface of precision parts such as hydraulic pumps and valve cores, and affecting the service life of the hydraulic splitting rod.

[0005] To achieve the above objectives, a rock pre-splitting auxiliary tool for blasting construction is provided, comprising: a hydraulic splitting rod body and a hydraulic oil conduit, wherein a connecting pipe is provided at the top of the hydraulic splitting rod body, a hydraulic oil filter assembly is provided at the top of the connecting pipe, and an interception net reinforcement assembly is provided on the hydraulic oil filter assembly.

A knob is fixedly installed on the other end of the rotating rod. A first positioning bead is provided on the outer wall of the rotating rod. A collar is rotatably installed on the outer wall of the rotating rod. A positioning groove is opened on the inner wall of the collar.

[0026] Reference Figure 1-5 This utility model provides an auxiliary tool for rock pre-splitting in blasting operations, which includes: a hydraulic splitting rod body 1 and a hydraulic oil conduit 3. A connecting pipe 5 is provided at the top of the hydraulic splitting rod body 1, a hydraulic oil filter assembly 4 is provided at the top of the connecting pipe 5, and an interception net reinforcement assembly 6 is provided on the hydraulic oil filter assembly 4.

[0027] The hydraulic oil filter assembly 4 includes a housing 41 and a backflow interceptor 43. An impurity filter 42 is fixedly installed on the inner wall of the bottom end of the housing 41 to filter impurities in the hydraulic oil. A rotating shaft and a rotating rod 45 are fixedly installed on the side wall of the backflow interceptor 43 to block impurities inside the housing 41 and prevent them from flowing back. A rotating groove is formed on the inner wall of the housing 41, and the rotating shaft is rotatably mounted on the inner wall of the groove. The cooperation between the rotating shaft and the groove allows the backflow interceptor 43 to be installed inside the housing 41. The rotating rod 45 passes through a through hole formed on the outer wall of the housing 41, and the other end of the rotating rod 45... A knob 46 is fixedly installed, which is used to drive the backflow interception net 43 to rotate. A first positioning bead 48 is provided on the outer wall of the rotating rod 45. The first positioning bead 48 is used to self-lock the rotating rod 45 on the knob 46. A collar 47 is rotatably installed on the outer wall of the rotating rod 45. The collar 47 cooperates with the first positioning bead 48 to achieve self-locking. A positioning groove is opened on the inner wall of the collar 47. The collar 47 is fixedly installed on the outer wall of the outer shell 41. A sealing ring 44 is fixedly installed on the side wall of the backflow interception net 43. Threads are provided on the outer walls of the upper and lower ends of the outer shell 41. An insertion hole is opened on the outer wall of the sealing ring 44.

[0028] The inner wall of one end of the hydraulic oil conduit 3 is threaded, and the inner wall of one end of the hydraulic oil conduit 3 is threaded to the outer wall of the upper end of the outer shell 41. The outer wall of the top end of the connecting pipe 5 is threaded, and the inner wall of the top end of the connecting pipe 5 is threaded to the outer wall of the lower end of the outer shell 41. The connecting pipe 5, the outer shell 41 and the hydraulic oil conduit 3 are threaded, so they are installed by means of threaded connection. A handle 2 is fixedly installed on the outer wall of the hydraulic splitting rod body 1.

[0029] The interception net reinforcement component 6 includes a fixing ring 64, which is fixedly installed on the inner wall of the mounting groove opened on the outer wall of the outer shell 41. A pull rod 62 is slidably installed on the inner wall of the fixing ring 64. A pull block 61 is fixedly installed at one end of the pull rod 62, and a pin 65 is fixedly installed at the other end of the pull rod 62. The pin 65 is made of rubber and has a curved edge at its tail end so that the pin 65 can be better inserted into the fixing ring 64. A second positioning bead 63 is provided on the outer wall of the pull rod 62. The second positioning bead 63 and the positioning groove inside the fixing ring 64 realize the self-locking function of the pull block 61. A positioning groove is opened on the inner wall of the fixing ring 64.

[0030] Working principle: The backflow interception net 43 set inside the outer shell 41 is initially in a vertical state, perpendicular to the impurity filter 42. Hydraulic oil is injected into the hydraulic splitting rod body 1 through the hydraulic oil conduit 3, the outer shell 41 and the connecting pipe 5. When the hydraulic oil passes through the outer shell 41, the impurity filter 42 set inside the outer shell 41 filters the impurities in the hydraulic oil. After the hydraulic splitting rod completes the pre-splitting operation, the knob 46 is turned first. The knob 46 drives the backflow interception net 43 to rotate through the rotating rod 45, so that the backflow interception net 43 rotates to ninety degrees, so that the backflow interception net 43 and the impurity filter 42 are in a parallel state. The first positioning bead 48 set on the outer wall of the rotating rod 45 separates from the original positioning groove and enters the next positioning groove set on the inner wall of the collar 47.

[0031] The pin 65 is initially inside the fixed ring 64, sealing the inside of the fixed ring 64. Pushing the pull block 61, the pull block 61 pushes the pin 65 into the insertion hole on the outer wall of the sealing ring 44 through the pull rod 62, completing the sealing of the insertion hole. Then, the hydraulic oil in the hydraulic split rod body 1 is extracted. The impurities on the impurity filter screen 42 are intercepted by the return interception net 43 when the hydraulic oil returns. After the hydraulic oil extraction is completed, the outer shell 41 is rotated. Both ends of the outer shell 41 are provided with threads. The inner wall of one end of the hydraulic oil conduit 3 and the inner wall of one end of the connecting pipe 5 are also provided with threads. By rotating the outer shell 41, the outer shell 41, the hydraulic oil conduit 3 and the connecting pipe 5 can be separated. Based on the above principle, the return interception net 43 is rotated to be perpendicular to the impurity filter screen 42, and then the inside of the outer shell 41 is cleaned.

[0032] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
