DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] See also Figure 1-5 The utility model provides a technical solution: a segmented quick-connection portable stone splitting device, comprising a flexible belt body 1, a liquid storage filling layer 2 filled in the flexible belt body 1, an air inlet pipe 3 installed in the middle of the flexible belt body 1, a first air outlet pipe 4 installed at the upper end of the flexible belt body 1 and an electronic match 6 arranged on the outside of the flexible belt body 1, a second air outlet pipe 5 corresponding to the position of the first air outlet pipe 4 is installed at the lower end of the flexible belt body 1, and a connecting mechanism for tool-free and convenient assembly and connection of pipelines between the stone splitting devices is arranged between the upper and lower ends of the air inlet pipe 3, the upper end of the first air outlet pipe 4 and the lower end of the second air outlet pipe 5.

[0033] Specifically, Figure 1-4 As shown, the connecting mechanism includes a connector holder 7 installed between the lower end of the air inlet pipe 3 and the lower end of the second air outlet pipe 5, a first bayonet 701 opened at the lower end of the connector holder 7 and connected to the air inlet pipe 3, a second bayonet 702 opened at the lower end of the connector holder 7 and connected to the lower end of the second air outlet pipe 5, a first quick-release sleeve 301 installed at the upper end of the air inlet pipe 3 and matching with the first bayonet 701, and a second quick-release sleeve 401 installed at the upper end of the first air outlet pipe 4 and matching with the second bayonet 702. When the first quick-release sleeve 301 is oriented toward and buckled into the first bayonet 701 on the connector holder 7, the air inlet pipe 3 between the two sections of the rock splitting devices will be connected, and the liquid path between the two sections of the rock splitting devices will be connected. At the same time, when the second quick-release sleeve 401 is oriented toward and buckled into the second bayonet 702 on the connector holder 7, the first air outlet pipe 4 and the second air outlet pipe 5 between the two sections of the rock splitting devices will be connected, and the gas path between the two sections of the rock splitting devices will be connected.

[0034] Specifically, Figure 1-4 As shown, a sealing plug 703 is detachably installed at the lower end of the first bayonet 701 and the second bayonet 702, which can be unscrewed from the first bayonet 701 and the second bayonet 702 when the gas circuit and the liquid circuit are connected, thereby facilitating the connection of the gas circuit and the liquid circuit between the multi-stage rock splitting devices.

[0035] Specifically, Figure 1-4 As shown, the flexible belt body 1 is made of an irrigation water belt. The flexible belt body 1 made of this material has the characteristics of low cost, good bending resistance and wear resistance. The two ends of the flexible belt body 1 are tied and fixed to the outside of the air intake pipe 3 by a first binding strap 8.

[0036] Among them, the liquid storage filling layer 2 is made of semi-finished roll paper or cylindrical hollow sponge. According to the actual construction conditions and usage needs, one of the above two groups of materials can be selected as the liquid storage filling layer 2. Both materials have the characteristics of light weight, low cost and good liquid absorption effect.

[0037] At the same time, the air intake pipe 3 is made of aluminum material. Compared with the air intake pipe 3 originally made of plastic material, it has better mechanical properties and can withstand low and high temperatures. At the same time, it has better working stability, avoiding the occurrence of rupture, air leakage and liquid leakage during more than ten uses. A plurality of exhaust holes 302 are equidistantly provided in the middle of the air intake pipe 3, so that liquid oxygen can be evenly filled into the liquid storage filling layer 2 of the flexible belt body 1 in multiple directions.

[0038] Specifically, Figure 1 , Figure 2 and Figure 4 As shown, the electronic match 6 is fixed to the outside of the flexible belt body 1 by being tied with a second binding strap 9, and a match head 601 is installed at the lower end of the electronic match 6, and the match head 601 is inserted inwardly into the interior of the flexible belt body 1. The selection of this external electronic ignition method effectively reduces the manufacturing difficulty of the stone splitting device. After the circuits of the electronic match 6 on the multiple-stage stone splitting devices are uniformly connected, the synchronous ignition operation inside the multiple-stage stone splitting devices can be realized. In actual use, the tungsten wire body electronic match 6 can also be used for power-on ignition operation.

[0039] Working principle: when in use, according to the depth of the pre-buried hole, take out the multi-section rock splitting device and place it near the pre-buried hole. For the rock splitting device at the bottom, it is necessary to unscrew the sealing cock 703 on the second bayonet 702 on the joint holder 7 in advance. At this time, the pipeline of the second air outlet pipe 5 can be opened, so that the lower exhaust treatment of the rock splitting device can be realized during the process of filling the rock splitting device with liquid oxygen. Then take out the upper section of the rock splitting device and remove the two sealing cocks 703 on the joint holder 7. At this time, the first bayonet 701 and the second bayonet 702 on the joint holder 7 can be exposed, and the first quick-release sleeve 301 and the second quick-release sleeve 401 on the rock splitting device at the bottom can be respectively oriented and buckled into the first bayonet 701 and the second bayonet 702 on the joint holder 7. At this time, the air inlet pipes 3 of the two sections of the rock splitting device will be connected, realizing the connection of the liquid circuit of the rock splitting device. At the same time, the second air outlet pipe 5 of the upper section of the rock splitting device Then it will be connected with the first air outlet pipe 4 of the lower section rock-breaking device, realizing the connection of the gas path of the rock-breaking device. Then, after the subsequent rock-breaking devices are assembled according to the above steps, the air inlet pipe 3 of the uppermost section rock-breaking device can be finally connected with the liquid oxygen dewar tank. The liquid oxygen dewar tank can fill the interior of the multi-section rock-breaking device with liquid oxygen through the air inlet pipe 3, and the liquid storage filling layer 2 can absorb the liquid oxygen. The second air outlet pipe 5 of the lower section rock-breaking device and the first air outlet pipe 4 of the upper section can realize the upper and lower exhaust operations of the combined rock-breaking device. In the actual operation process, in order to be safer and eliminate potential safety hazards, when the liquid oxygen dewar tank is connected to the rock-breaking device, the liquid oxygen inside the liquid oxygen dewar tank is output in liquid form, and the low-temperature pipeline is processed and output by the vaporizer as gas. In addition, the liquid oxygen dewar tank can be equipped with a gas return valve to prepare for potential safety hazards caused by gas reflux, thereby ensuring the safety and stability of the entire rock-breaking operation process.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
