[0002] The ventilation tunnel project includes three parts: the upper horizontal section of the ventilation shaft, the pilot shaft and the ventilation tunnel branch tunnel. Ensuring the unobstructed flow of the pilot shaft is the key to the normal construction of the ventilation tunnel project.

[0003] After analysis, it was found that the blockage of the pilot shaft was caused by the solidification and compaction of blasting slag. The slag in the pilot shaft was in danger of collapse at any time, and the blocked part was too far away from the bottom of the pilot shaft. The conventional method of clearing the lower part of the pilot shaft by poking the gun rod with a crowbar or connecting the gun rod to collapse the gun and shaking the gun, etc., had great safety hazards; and the mining rocket launcher treatment method, the iron pipe and steel rope blasting method and some special treatment methods (such as the seat gun method, digging method and watering method, etc.) were too expensive or difficult to construct.

[0004] Therefore, it is particularly important to design a guide shaft blockage treatment device to solve the above-mentioned defects. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model designs a device for treating a well blockage, which aims to solve the technical problems of the prior art of treating a well blockage, such as great potential safety hazards, high costs and great construction difficulty.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A guide shaft blockage treatment device comprises a hydrogen balloon, a blasting assembly and a balancing assembly, wherein a protective frame is installed on the outside of the hydrogen balloon, the blasting assembly is installed on the top of the protective frame, a connecting frame is installed on the bottom of the protective frame, and the balancing assembly is installed on the bottom of the connecting frame;

[0008] The blasting assembly includes a support plate, a top frame, support rods and an explosive placement tube. The support plate is fixedly installed on the top of the protective frame, the top frame is installed above the support plate, multiple groups of support rods are installed between the top frame and the support plate, and the explosive placement tube is fixedly installed on the top of the support plate and is located on the inner side of the multiple groups of support rods.

[0009] As a preferred solution of the utility model, the balancing assembly includes a first connecting plate, a connecting ring, a connecting frame, a first connecting rod, a telescopic rod and an outer support plate, the first connecting plate is installed at the bottom of the connecting frame, the connecting ring is installed at the outer side of the first connecting plate, the connecting frame is installed below the connecting ring, multiple groups of the first connecting rods are fixedly installed between the connecting ring and the connecting frame, multiple groups of the telescopic rods are respectively installed at the upper and lower ends of the first connecting rod, and the outer support plate is fixedly installed at one end of the telescopic rod away from the first connecting rod.

[0010] As a preferred solution of the utility model, a second connecting rod is fixedly connected to the bottom of the connecting frame, and the bottom of the second connecting rod is fixedly connected to the first connecting plate through a plurality of sets of screws.

[0011] As a preferred solution of the utility model, the telescopic rod is composed of a connecting tube and an outer support rod, the outer support rod is slidably connected to the inside of the connecting tube, and a spring is installed at one end of the outer support rod located inside the connecting tube.

[0012] As a preferred solution of the utility model, a second connecting plate is fixedly connected to the inner side of the connecting frame, a rope threading ring is installed at the bottom of the second connecting plate, a pull rope is connected to the outer side of the rope threading ring, and moving wheels are fixedly connected to the upper and lower ends of the outer support plate.

[0013] As a preferred solution of the utility model, the protection frame is fixedly connected with a protection ring, collision columns are evenly connected to the outside of the protection ring, and a rubber ball is fixedly connected to one end of the collision column away from the protection ring.

[0014] As a preferred solution of the utility model, multiple groups of support rods are evenly spaced around the top of the support plate, the upper and lower ends of the support rods are fixedly connected to the support plate and the top frame respectively, and the height of the explosive placement tube is the same as the height of the top frame.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] When the utility model processes the blockage in the pilot well, at the wellhead position of the pilot well, a hydrogen balloon is made by using the principle that hydrogen is lighter than air, and explosives are placed inside the explosive placement tube. Under the action of air buoyancy, the explosives are brought to the bottom of the blocked part, and the pull rope is connected by a rope ring. The rising height of the hydrogen balloon can be adjusted by controlling the length of the pull rope. After the connecting frame is connected to the first connecting plate through the second connecting rod, the balance component below can be used as a counterweight, so that the overall center of gravity of the hydrogen balloon is vertically downward and balanced. After the hydrogen balloon rises, the outer support rod is pushed outward under the action of the spring, so that the outer support plate is attached to the well wall, and when the outer support plate is attached to the well wall, the moving wheel contacts the well wall, and as the hydrogen balloon rises, the moving wheel rolls accordingly, thereby ensuring that the hydrogen balloon remains at the center of the pilot well and rises stably. When the top frame is lifted, the outside of the hydrogen balloon is protected by the protective frame and the protective ring on the outside. At the same time, the rubber ball on the outside of the collision column can prevent the hydrogen balloon from being affected by the impact. After the top frame reaches the bottom of the blocked part, the bottom of the pull rope is fixed so that the pull rope is as vertical as possible to keep the balance of the hydrogen balloon. The operator then evacuates to a safe position and detonates remotely until the explosive reaches the bottom of the blocked part and accurately blasts the center. External protection is provided to the explosive placement tube through multiple support rods and the top frame to prevent the explosive from being squeezed and damaged during the push, affecting its use. After the top frame supports the blocked part, since the explosive is located on the inner side of the explosive placement tube, the impact force is concentrated upward after the blasting. It is not only simple to operate and has low cost, but also more accurate and stable blasting, which improves the blasting effect and protects the guide shaft at the same time.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A device for treating well blockage includes a hydrogen balloon 1, a blasting assembly 2 and a balancing assembly 3. A protective frame 4 is installed on the outside of the hydrogen balloon 1, the blasting assembly 2 is installed on the top of the protective frame 4, a connecting frame 5 is installed on the bottom of the protective frame 4, and the balancing assembly 3 is installed on the bottom of the connecting frame 5.

[0026] First, in this embodiment, the specific structure of the blasting assembly 2 is as follows:

[0027] The blasting assembly 2 includes a support plate 201, a top frame 202, a support rod 203 and an explosive placement tube 204. The support plate 201 is fixedly installed on the top of the protective frame 4, the top frame 202 is installed above the support plate 201, and multiple groups of support rods 203 are installed between the top frame 202 and the support plate 201. The explosive placement tube 204 is fixedly installed on the top of the support plate 201 and is located on the inner side of the multiple groups of support rods 203.

[0028] Furthermore, the balancing assembly 3 includes a first connecting plate 301, a connecting ring 302, a connecting frame 303, a first connecting rod 304, a telescopic rod 305 and an outer support plate 306. The first connecting plate 301 is installed at the bottom of the connecting frame 5, the connecting ring 302 is installed on the outside of the first connecting plate 301, the connecting frame 303 is installed below the connecting ring 302, multiple groups of first connecting rods 304 are fixedly installed between the connecting ring 302 and the connecting frame 303, multiple groups of telescopic rods 305 are respectively installed at the upper and lower ends of the first connecting rod 304, and the outer support plate 306 is fixedly installed at one end of the telescopic rod 305 away from the first connecting rod 304. When the blockage in the pilot well is to be treated, a hydrogen balloon 1 is made at the wellhead position of the pilot well by using the principle that hydrogen is lighter than air, and explosives are placed inside the explosive placement tube 204. The explosives are brought to the bottom of the blocked part under the action of air buoyancy, and then blasting is performed to achieve the purpose of unblocking the pilot well through blasting vibration. However, since the hydrogen balloon 1 is prone to deviation during the upward movement, the blasting position of the explosives is prone to stick to the well wall, causing damage to the pilot well after blasting. At this time, multiple groups of first connecting rods 304 are fixed in the middle through connecting rings 302 and connecting frames 303, and then the outer support plates 306 are supported and attached to the well wall through multiple groups of telescopic rods 305.

[0029] Then, a second connecting rod 501 is fixedly connected to the bottom of the connecting frame 5, and the bottom of the second connecting rod 501 is fixedly connected to the first connecting plate 301 through multiple sets of screws. After the connecting frame 5 is connected to the first connecting plate 301 through the second connecting rod 501, the balance assembly 3 below can be used as a counterweight, thereby allowing the overall center of gravity of the hydrogen balloon 1 to remain balanced vertically downward.

[0030] Furthermore, the telescopic rod 305 is composed of a connecting tube 307 and an outer support rod 308. The outer support rod 308 is slidably connected to the inside of the connecting tube 307, and a spring is installed at one end of the outer support rod 308 located inside the connecting tube 307. Under the action of the spring, the outer support rod 308 is pushed outward, so that the outer support plate 306 is attached to the well wall.

[0031] The second connecting plate 309 is fixedly connected to the inner side of the connecting frame 303, and a rope threading ring 310 is installed at the bottom of the second connecting plate 309. A pull rope 311 is connected to the outer side of the rope threading ring 310. The upper and lower ends of the outer support plate 306 are fixedly connected with moving wheels 312. The pull rope 311 is connected through the rope threading ring 310. The rising height of the hydrogen balloon 1 can be adjusted by controlling the length of the pull rope 311. After the top frame 202 reaches the bottom of the blocked part, the bottom of the pull rope 311 is fixed so that the pull rope 311 is as vertical as possible to maintain the balance of the hydrogen balloon 1. Then the operator evacuates to a safe position and then remotely detonates. When the outer support plate 306 is attached to the well wall, the moving wheel 312 contacts the well wall. As the hydrogen balloon 1 rises, the moving wheel 312 rolls accordingly, thereby ensuring that the hydrogen balloon 1 remains in the center of the guide shaft and rises stably until the explosive reaches the bottom of the blocked part, and its center is accurately blasted, thereby improving the blasting effect and protecting the guide shaft at the same time.

[0032] Secondly, the protective frame 4 is fixedly connected to a protective ring 401, and collision columns 402 are evenly spacedly connected to the outside of the protective ring 401. A rubber ball 403 is fixedly connected to the end of the collision column 402 away from the protective ring 401. When the hydrogen balloon 1 rises, the protective frame 4 and the outer protective ring 401 provide protection for the outside of the hydrogen balloon 1. At the same time, the rubber ball 403 on the outer side of the collision column 402 can prevent the hydrogen balloon 1 from being affected by collision.

[0033] Finally, multiple groups of support rods 203 are evenly spaced around the top of the support plate 201, and the upper and lower ends of the support rods 203 are fixedly connected to the support plate 201 and the top frame 202 respectively. The height of the explosive placement tube 204 is the same as the height of the top frame 202. The multiple support rods 203 and the top frame 202 provide external protection for the explosive placement tube 204 to prevent the explosives from being squeezed and damaged during the top, which affects their use. After the top frame 202 supports the blocked part, since the explosives are located on the inner side of the explosive placement tube 204, the impact force after the blasting is concentrated upward, thereby quickly clearing the guide well and improving the clearing effect.

[0034] In this embodiment, the implementation scenario is as follows: when dealing with the blockage in the pilot well, at the wellhead position of the pilot well, a hydrogen balloon 1 is made based on the principle that hydrogen is lighter than air, and explosives are placed inside the explosive placement tube 204. Under the action of air buoyancy, the explosives are brought to the bottom of the blockage part, and the pull rope 311 is connected through the rope ring 310. By controlling the length of the pull rope 311, the rising height of the hydrogen balloon 1 can be adjusted. After the connecting frame 5 is connected to the first connecting plate 301 through the second connecting rod 501, the balance component 3 below can be used as a counterweight, so that the hydrogen balloon 1 can be placed inside the explosive placement tube 204. The center of gravity of the balloon 1 is kept vertically downward to maintain balance. After the hydrogen balloon 1 rises, the outer support rod 308 is pushed outward under the action of the spring, so that the outer support plate 306 is attached to the well wall. When the outer support plate 306 is attached to the well wall, the moving wheel 312 contacts the well wall. As the hydrogen balloon 1 rises, the moving wheel 312 rolls accordingly, thereby ensuring that the hydrogen balloon 1 remains in the center of the guide well and rises stably. When the hydrogen balloon 1 rises, the outer side of the hydrogen balloon 1 is protected by the protective frame 4 and the outer protective ring 401. At the same time, the rubber ball 403 on the outer side of the collision column 402 can prevent the hydrogen from being hit. The balloon 1 is affected by the collision. After the top frame 202 reaches the bottom of the blocked part, the bottom of the pull rope 311 is fixed so that the pull rope 311 is as vertical as possible to keep the balance of the hydrogen balloon 1. Then the operator evacuates to a safe position and detonates remotely until the explosive reaches the bottom of the blocked part and accurately blasts the center. The multiple support rods 203 and the top frame 202 provide external protection for the explosive placement tube 204 to prevent the explosive from being squeezed and damaged during the push-up and affecting its use. After the top frame 202 supports the blocked part, since the explosive is located in the explosive placement tube 20 4, the impact force after blasting is concentrated upward, the blasting effect is improved while protecting the guide well, the whole operation process is simple and convenient, compared with the existing guide well blockage treatment method, the utility model uses the principle that hydrogen is lighter than air to make a hydrogen balloon 1, and places the explosive inside the explosive placement tube 204, and under the action of air buoyancy, the explosive is brought to the bottom of the blocked part, and then blasting is carried out to achieve the purpose of unblocking the guide well through the blasting vibration. It is not only simple to operate and low in cost, but also more accurate and stable in blasting, and the blasting effect is improved while protecting the guide well.
