Abstract
Description
Technical Field
[0001] This utility model belongs to the field of blasting engineering technology, and in particular relates to a segmented carbon dioxide gas expansion blasting device. Background Technology
[0002] The carbon dioxide gas expansion blasting device is a device that uses the rapid vaporization and expansion of liquid carbon dioxide upon heating to generate high pressure, thereby achieving the blasting function. Its working principle is as follows: liquid carbon dioxide is filled into the storage tube, and the liquid carbon dioxide absorbs a large amount of heat in a very short time and rapidly vaporizes and expands through an electric ignition head or chemical heating agent. The high-pressure gas generated pushes the expansion tube to rupture, thereby achieving the purpose of blasting.
[0003] However, existing traditional carbon dioxide blasting devices use an integral liquid storage pipe structure. The integral liquid storage pipe is quite long, generally several meters long, and weighs tens or even hundreds of kilograms. In practical applications, due to its excessive length and weight, the transportation and installation process is extremely difficult and requires a lot of manpower and resources.
[0004] To address these issues, we provide a segmented carbon dioxide gas expansion explosion device. Utility Model Content
[0005] The purpose of this invention is to provide a segmented carbon dioxide gas expansion and explosion device. Through the cooperation of the first liquid storage pipe, the second liquid storage pipe and the connecting components, the invention solves the problem that the existing carbon dioxide gas expansion and explosion device adopts an integral liquid storage pipe structure, which makes the transportation and installation process extremely difficult.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.
[0007] This utility model relates to a segmented carbon dioxide gas expansion explosion device, comprising a first liquid storage pipe and a second liquid storage pipe. A controller is provided on one side of the inner cavity of both the first and second liquid storage pipes. An excitation tube is provided on one side of the controller. A connecting assembly is provided between the first and second liquid storage pipes. Connectors are provided at both ends of both the first and second liquid storage pipes. A venting hole is provided at the top of both the first and second liquid storage pipes, and a venting plate is provided inside the venting hole. The connecting assembly includes a fixing frame. One side of the fixing frame is fixedly connected to the surface of the first liquid storage pipe. Connecting plates are movably connected to the top and bottom of the inner cavity of the fixing frame. A locking block is fixedly connected to the opposite side of each connecting plate. A connecting frame is fixedly connected to one side of the second liquid storage pipe.
[0008] The present invention is further configured such that a fixed arc plate is fixedly connected to the top of both the first liquid storage tube and the second liquid storage tube. A groove is provided on one side of the fixed arc plate. The hook is locked in the groove on one side of the fixed arc plate by a hoisting device, which makes it easier to move the blasting device.
[0009] The present invention is further configured such that teeth are fixedly connected to opposite sides of the connecting plates. The teeth are trapezoidal in shape. When the two connecting plates are rotated to approach each other, the teeth on one side of the connecting plates will mesh and lock together, thereby improving the overall strength of the two connecting plates.
[0010] The present invention is further configured such that a limiting strip is fixedly connected to the surface of the connecting plate and one side of the locking block, and one side of the limiting strip is in contact with the surface of the connecting frame. When the connecting plate is rotated, the locking blocks on one side of the connecting plate are respectively locked into the inner cavity of the connecting frame. At this time, the two limiting strips are respectively pressed against the surface of the connecting frame to form a stable locking structure.
[0011] The present invention is further configured such that a positioning plate is fixedly connected to the bottom of one side of the first liquid storage tube, and an abutment plate is fixedly connected to the bottom of one side of the second liquid storage tube. A slot is provided on the surface of the positioning plate, and an insertion block is fixedly connected to one side of the abutment plate. As the first liquid storage tube and the second liquid storage tube approach each other, the insertion block on the side of the abutment plate is inserted into the slot on the surface of the positioning plate. The reinforcement structure composed of the positioning plate and the abutment plate can improve the connection strength between the first liquid storage tube and the second liquid storage tube.
[0012] The present invention is further provided with a protective sleeve on the surface of the first liquid storage tube and the second liquid storage tube and on the outside of the connector. A magnetic sheet is provided on one side of the protective sleeve. The two protective sleeves abut against each other to form a sealed protective structure, which can protect the connection of the connector.
[0013] The present invention is further configured such that a filling port is provided at the top of both the first liquid storage tube and the second liquid storage tube, and a one-way valve is provided in the inner cavity of the filling port. Liquid carbon dioxide can be filled into the first liquid storage tube and the second liquid storage tube through the filling port, and the one-way valve can prevent the liquid carbon dioxide from flowing back after filling is completed.
[0014] The present invention is further configured such that positioning holes are provided on the surfaces of the locking blocks and the connecting frame, and internal threads are provided on the inner walls of the positioning holes. After the locking blocks are locked together in the inner cavity of the connecting frame, the fixing bolts are screwed into the positioning holes to fix the two locking blocks in the inner cavity of the connecting frame, so that the connecting components are connected and formed, and the connection of the two expansion bursting devices is completed.
[0015] The present invention has the following beneficial effects.
[0016] 1. When using this utility model, multiple sets of expansion blasting devices can be transported to the blasting point. By rotating the connecting plate, the locking block is inserted into the inner cavity of the connecting frame, and the locking block is fixed in the connecting frame using fixing bolts. This completes the connection between the first liquid storage tube and the second liquid storage tube. Subsequent connections are made in the same way. This connection method is simple to operate and allows multiple sets of devices to be flexibly connected into an expansion blasting device of a specified length according to actual blasting needs.
[0017] 2. This utility model uses an ignition head in an excitation tube to rapidly burn the exothermic propellant, releasing sufficient heat in a short time to quickly heat the liquid carbon dioxide, causing it to rapidly expand from a liquid state to a gaseous state. When the pressure exceeds the preset threshold of the energy release plate, the energy release plate ruptures instantly, and the high-pressure carbon dioxide gas is ejected at high speed through the pressure relief hole. The shock wave and high-speed airflow generated by the gas expansion act on the surrounding medium to achieve explosion. Attached Figure Description

A connecting component 5 is provided between the first liquid storage pipe 1 and the second liquid storage pipe 2. A connector 6 is provided at both ends of the first liquid storage pipe 1 and the second liquid storage pipe 2. A venting hole 7 is provided at the top of the first liquid storage pipe 1 and the venting hole 7 is provided with a venting plate 8 in the inner cavity. The connecting component 5 includes a fixing frame 501. One side of the fixing frame 501 is fixedly connected to the surface of the first liquid storage pipe 1. A connecting plate 502 is movably connected to the top and bottom of the inner cavity of the fixing frame 501. A locking block 503 is fixedly connected to the opposite side of the connecting plate 502. A connecting frame 504 is fixedly connected to one side of the second liquid storage pipe 2.
[0028] Specifically: Move the first liquid storage tube 1 and the second liquid storage tube 2 until they are close to each other at a certain distance. Then, rotate the connecting plate 502 until the locking block 503 on one side of the two connecting plates 502 is inserted into the inner cavity of the connecting frame 504. Fix the locking block 503 in the connecting frame 504 with fixing bolts to complete the connection of the first liquid storage tube 1 and the second liquid storage tube 2. The subsequent connection method is as above. Insert the connected expansion blasting device of the specified length into the drilled directional hole. The ignition head in the ignition tube 4 makes the exothermic material burn rapidly to release enough heat in a short time. The liquid carbon dioxide is rapidly heated and undergoes a phase change. The carbon dioxide rapidly expands from liquid to gas. When the pressure exceeds the preset threshold of the energy release plate 8, the energy release plate 8 ruptures instantly, and the high-pressure carbon dioxide gas is ejected at high speed through the pressure relief hole.
[0029] Example 2
[0030] Please see Figure 1-5Based on Embodiment 1, a fixing arc plate 9 is fixedly connected to the top of both the first liquid storage tube 1 and the second liquid storage tube 2. A groove is provided on one side of the fixing arc plate 9. Teeth are fixedly connected to the opposite side of the connecting plate 502. The teeth are trapezoidal in shape. A limit strip is fixedly connected to the surface of the connecting plate 502 and to one side of the locking block 503. One side of the limit strip contacts the surface of the connecting frame 504. A positioning plate is fixedly connected to the bottom of one side of the first liquid storage tube 1, and a positioning plate is fixedly connected to the bottom of one side of the second liquid storage tube 2. A contact plate is attached, and a slot is provided on the surface of the positioning plate. A plug is fixedly connected to one side of the contact plate. A protective sleeve is provided on the surface of the first liquid storage tube 1 and the second liquid storage tube 2 and on the outside of the connector 6. A filling port 10 is provided at the top of the first liquid storage tube 1 and the second liquid storage tube 2. A one-way valve is provided in the inner cavity of the filling port 10. Positioning holes are provided on the surface of the locking block 503 and the connecting frame 504. The inner wall of the positioning hole is provided with internal thread. The locking blocks 503 are locked together in the inner cavity of the connecting frame 504.
[0031] Specifically: By using hoisting equipment to engage the hook in the groove on one side of the fixed arc plate 9, the blasting device can be moved more easily. Rotating the two connecting plates 502 until they are close to each other, the teeth on one side of the connecting plates 502 will mesh and lock together, improving the overall strength of the two connecting plates 502. Rotating the connecting plates 502 until the locking blocks 503 on one side of the connecting plates 502 respectively lock into the inner cavity of the connecting frame 504, at which point the two limiting strips respectively abut against the surface of the connecting frame 504, thus forming a stable locking structure. As the first liquid storage tube 1 and the second liquid storage tube 2 approach each other, the insert block on one side of the abutment plate inserts into the surface of the positioning plate. In the slot, the reinforcement structure composed of the positioning plate and the abutment plate can improve the connection strength of the first liquid storage tube 1 and the second liquid storage tube 2. A magnetic sheet is provided on one side of the protective sleeve. The two protective sleeves abut against each other to form a sealed protective structure, which can protect the connection of the connector 6. Liquid carbon dioxide can be filled into the first liquid storage tube 1 and the second liquid storage tube 2 through the filling port 10. The one-way valve can prevent the liquid carbon dioxide from flowing back after filling. The fixing bolt is screwed into the positioning hole to fix the two locking blocks 503 in the inner cavity of the connecting frame 504, so that the connecting component 5 is connected and formed, and the connection of the two expansion bursting devices is completed.
[0032] The working principle of this utility model is as follows: Multiple sets of expansion blasting devices are transported to the blasting point. Then, the first liquid storage pipe 1 and the second liquid storage pipe 2 are moved until they are close to each other at a certain distance. The connecting plates 502 are rotated until the locking blocks 503 on one side of the two connecting plates 502 are inserted into the inner cavity of the connecting frame 504. The locking blocks 503 are fixed in the connecting frame 504 by fixing bolts, thus completing the connection of the first liquid storage pipe 1 and the second liquid storage pipe 2. The subsequent connection method is as above. The connected expansion blasting device of the specified length is inserted into the drilled directional hole. The ignition head in the excitation tube 4 causes the exothermic material to burn rapidly, so as to release enough heat in a short time. The liquid carbon dioxide is rapidly heated and undergoes a phase change. The carbon dioxide rapidly expands from the liquid state to the gas state. When the pressure exceeds the preset threshold of the energy release plate 8, the energy release plate 8 ruptures instantly. The high-pressure carbon dioxide gas is ejected at high speed through the pressure relief hole. The shock wave and high-speed airflow generated by the gas expansion act on the surrounding medium, causing it to rupture or shift, thus achieving the blasting effect.
