Description

Technical Field

[0001] This application relates to the field of static blasting technology, and more particularly to a static blasting device. Background Technology

[0002] In the field of static blasting technology, hydraulic rock splitters, with their environmentally friendly and safe characteristics, have become an important alternative to traditional explosive blasting equipment and are widely used in production.

[0003] Currently, when using traditional hydraulic rock splitters for static blasting, rock fragments become embedded in the gap between the splitter head and the borehole wall, causing the hydraulic rock splitter to become stuck and difficult to remove from the working hole, which is detrimental to static blasting operations. Furthermore, the pipes on traditional hydraulic rock splitters are generally directly exposed to the construction environment, making them susceptible to damage from external debris or sharp objects, which greatly affects the normal use of the hydraulic rock splitter.

[0004] Based on the above reasons, this utility model proposes a static blasting device that can remove the splitting rod and improve the protection of the pipeline. Utility Model Content

[0005] In view of the above problems, this application provides a static blasting device to solve the problem that the equipment is prone to jamming and damage during static blasting in the prior art.

[0006] This application provides a static blasting device, including a hydraulic splitting rod. A fixed rod is fixedly connected to the top surface of the hydraulic splitting rod, and a fixed plate is fixedly connected to the top end of the fixed rod. A fixed tube is installed on the fixed plate, and a movable tube is sleeved on the fixed tube. A positioning bolt is threadedly connected to the side wall of the movable tube. An annular shell is fixedly connected to the fixed plate, and a plurality of splicing rods are evenly distributed threaded on the annular shell. A rotation drive assembly is provided in the inner cavity of the annular shell.

[0007] In some embodiments, the rotary drive assembly includes a ring gear, which is movably connected to the inner sidewall of the annular shell. A plurality of first gears, which are movably connected to the annular shell, are evenly distributed and meshed on the ring gear. Each of the first gears has a through hole at the center of its sidewall that matches the splicing rod. The splicing rod passes through the through hole and is movably connected to the first gear. A motor is fixedly connected to the top surface of the annular shell. A rotating shaft is fixedly connected to the rotor of the motor.

Each threaded rod has a connecting rod fixedly connected to its top end, and each threaded rod has a threaded hole at its bottom end. The connecting rod has threads on its outer wall and is threadedly connected to the threaded hole.

[0009] In some embodiments, a base plate is threaded into the threaded hole on the lowest threaded rod, and the base plate is circular with a diameter larger than that of the threaded rod.

[0010] In some embodiments, vertical grooves are provided on the sidewalls of the threaded rod, the vertical grooves are located at the same cross section, and a fixing block that is movably connected to the vertical groove is fixedly connected inside the through hole.

[0011] In some embodiments, the same horizontal plate is fixedly connected to the two fixed tubes, and a first bolt is provided at the center of the side wall of the horizontal plate. The first bolt passes through the fixed plate and is threadedly connected to a first nut.

[0029] To facilitate understanding of the technical solutions in the embodiments of this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0030] like Figure 1-6 As shown, this application embodiment provides a static blasting device, including a hydraulic splitting rod 1, a fixed rod 2 fixedly connected to the top surface of the hydraulic splitting rod 1, a fixed plate 3 fixedly connected to the top end of the fixed rod 2, a fixed pipe 4 installed on the fixed plate 3, a movable pipe 5 sleeved on the fixed pipe 4, a positioning bolt 6 threadedly connected to the side wall of the movable pipe 5, a common horizontal plate 21 fixedly connected to the two fixed pipes 4, a first bolt 22 provided at the center of the side wall of the horizontal plate 21, the first bolt 22 passing through the fixed plate 3 and threadedly connected to a first nut 23;

[0031] In the technical solution of this embodiment, by using a pipe that passes through the fixed pipe 4 and the movable pipe 5, and completing the installation connection between the pipe and the hydraulic splitting rod 1, the horizontal plate 21 is fixedly installed on the fixed plate 3 using the first bolt 22 and the first nut 23, and the movable pipe 5 is pushed to cover the pipe connection. The fixed pipe 4 and the movable pipe 5 are locked by rotating the positioning bolt 6. This can achieve protection for the pipe near the hydraulic splitting rod 1, reduce the damage to the pipe by gravel and other materials when the hydraulic splitting rod 1 is running, improve protection, and ensure the stable operation of the hydraulic splitting rod 1.

[0032] like Figure 3 and Figure 4 As shown, an annular shell 7 is fixedly connected to the fixed plate 3. Two connecting plates 24 are symmetrically fixedly connected to the bottom surface of the annular shell 7. A second bolt 25 is movably connected to the connecting plate 24. The second bolt 25 passes through the fixed plate 3 and is threadedly connected to a second nut 26.

[0033] In the technical solution of this embodiment, when the hydraulic splitting rod 1 is stuck in the hole, the operator can use the second bolt 25 and the second nut 26 to achieve a fixed installation connection between the annular shell 7 and the fixing plate 3, which facilitates the subsequent removal of the hydraulic splitting rod 1.

[0034] like Figure 3 and Figure 6 As shown, several splicing rods 8 are evenly distributed on the annular shell 7 and connected by threads. Each splicing rod 8 includes a threaded rod 15. Several threaded rods 15 are provided. A connecting rod 16 is fixedly connected to the top of each threaded rod 15. A threaded hole 17 is opened at the bottom of each threaded rod 15. The outer wall of the connecting rod 16 is threaded and threadedly connected to the threaded hole 17.

[0035] In the technical solution of this embodiment, when the hydraulic splitting rod 1 is removed, an appropriate number of threaded rods 15 can be selected according to the insertion depth of the hydraulic splitting rod 1. The length of the splicing rod 8 can be adjusted by connecting the connecting rod 16 between the threaded rods 15 and the threaded hole 17, which facilitates the subsequent removal and operation of the hydraulic splitting rod 1.

[0036] Furthermore, a base plate 18 is installed in the threaded hole 17 on the lowest threaded rod 15. The base plate 18 is circular and its diameter is larger than that of the threaded rod 15, which can effectively improve the support stability during the removal operation and facilitate operation.

[0037] like Figure 3 and Figure 4As shown, a rotary drive assembly 9 is provided in the inner cavity of the annular shell 7. The rotary drive assembly 9 includes an annular gear 10, which is movably connected to the inner side wall of the annular shell 7. Several first gears 11 that are movably connected to the annular shell 7 are evenly distributed and meshed on the annular gear 10. The center of the side wall of each first gear 11 is provided with a through hole that matches the splicing rod 8. The splicing rod 8 passes through the through hole and is movably connected to the first gear 11. Vertical grooves 19 are provided on the side wall of each threaded rod 15. The vertical grooves 19 are located at the same cross section. A fixing block 20 that is movably connected to the vertical groove 19 is fixedly connected in the through hole. A motor 12 is fixedly connected to the top surface of the annular shell 7. A rotating shaft 13 is fixedly connected to the rotor of the motor 12. A second gear 14 that meshes with the annular gear 10 is fixedly connected to the rotating shaft 13.

[0038] In the technical solution of this embodiment, when the hydraulic splitting rod 1 is removed, the motor 12 is started. The motor 12 drives the second gear 14 to rotate through the rotating shaft 13. The second gear 14 meshes with the ring gear 10 to rotate. The ring gear 10 meshes with the first gear 11 to rotate. The first gear 11 drives the splicing rod 8 to rotate, so that the splicing rod 8 moves towards the side of the hydraulic splitting rod 1. When the base plate 18 is pressed against the rock, the continued drive of the motor 12 can cause the annular shell 7 to move the hydraulic splitting rod 1, so that the hydraulic splitting rod 1 can be pulled out from the hole, which is convenient for static blasting.
