Abstract
The utility model discloses a kind of shotcrete pipe joint anti-block apparatus, a kind of shotcrete pipe joint anti-block apparatus, wherein, described anti-block apparatus includes shotcrete pipe joint, nexine iron ring and outer layer iron ring, the inner side of shotcrete pipe joint is provided with nexine iron ring, nexine iron ring embeds on the inwall of described shotcrete pipe joint, fixes with described shotcrete pipe and is connected；Outer layer iron ring and nexine iron ring are stuck in shotcrete pipe between two-layer iron sheet.The utility model make use of the intensity of iron ring and the characteristic that wearability is higher than the wearability of sebific duct, the inboard of shotcrete pipe joint is added one layer of iron ring, hose clamp will be whitewashed between two-layer iron ring, so Gunning material would not be ground away the flexible pipe of joint, when preventing from whitewashing, joint sebific duct is ground rotten by Gunning material, cause joint accumulation Gunning material, block shotcrete pipe.Reduce the abrasion of Gunning material butt joint during daily whitewashing.
Description
Technical field
The utility model relates to underground work field, especially a kind of shotcrete pipe joint anti-block apparatus.
Background technology
Spray operation is one of one important procedure of underground coal mine developing sector, but shotcrete pipe during whitewashing
Blocking is always the big persistent ailment perplexing worker, the reason that shotcrete pipe blocks a lot, have in as wet in Gunning material, Gunning material foreign matter,
Shotcrete pipe joint is unreasonable, but most reason is because shotcrete pipe unreasonable structure, and current shotcrete pipe joint is all
It is outside one layer of flexible pipe, to add one layer of iron ring, during routine use, often due to Gunning material is by rotten for flexible pipe junction mill, lead
Cause shotcrete pipe joint residual Gunning material, accumulate over a long period and may result in the blocking of shotcrete pipe joint.
Utility model content
In sum, in order to overcome the deficiency of prior art problem, the utility model provides a kind of shotcrete pipe joint to be prevented
Block apparatus, durable shotcrete pipe joint anti-block apparatus, this device is that the inboard of joint arranges one layer of iron ring, pipe clamp of whitewashing
Between two-layer iron sheet, when preventing from whitewashing, Gunning material is by rotten for sebific duct mill in joint, causes joint accumulation Gunning material, blocking
Shotcrete pipe.
A kind of shotcrete pipe joint anti-block apparatus, wherein, described anti-block apparatus includes shotcrete pipe joint, nexine iron ring and outer layer
Iron ring, is provided with nexine iron ring in the inner side of shotcrete pipe joint, and nexine iron ring embeds on the inwall of described shotcrete pipe joint, with institute
State the fixing connection of shotcrete pipe.
Further, outer layer iron ring and nexine iron ring are stuck in shotcrete pipe between two-layer iron sheet.
Compared with prior art, the beneficial effects of the utility model are:
1st, the inner side of the joint at shotcrete pipe for the utility model is provided with nexine iron ring, and outer layer iron ring and nexine iron ring will
Shotcrete pipe is stuck between two-layer iron sheet, and when preventing from whitewashing, Gunning material is by rotten for sebific duct mill in joint, causes joint accumulation spray
Slurry, blocks shotcrete pipe.Reduce the abrasion of Gunning material butt joint during daily whitewashing.
2nd, the blocking number of times during the utility model reduces whitewashing, improves efficiency.
Brief description
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings, the utility model is described in more detail.
Spray operation is one of one important procedure of underground coal mine developing sector, but shotcrete pipe during whitewashing
Blocking is always the big persistent ailment perplexing worker, the reason that shotcrete pipe blocks a lot, have in as wet in Gunning material, Gunning material foreign matter,
Shotcrete pipe joint is unreasonable, but most reason is because shotcrete pipe unreasonable structure, and current shotcrete pipe joint is all
It is outside one layer of flexible pipe, to add one layer of iron ring, during routine use, often due to Gunning material is by rotten for flexible pipe junction mill, lead
Cause shotcrete pipe joint residual Gunning material, accumulate over a long period and may result in the blocking of shotcrete pipe joint.
The utility model is the novel spraying pipe joint anti-block apparatus developed in practice, in the joint of shotcrete pipe
Side is provided with nexine iron ring, and outer layer iron ring and nexine iron ring are stuck in shotcrete pipe between two-layer iron sheet, prevents from spraying when whitewashing
Slurry, by rotten for sebific duct mill in joint, cause joint accumulation Gunning material, blocks shotcrete pipe.
As it is shown in figure 1, the structure of the anti-gambling device described in the utility model embodiment: this device make use of the intensity of iron ring
The characteristic higher than the wearability of sebific duct with wearability, adds nexine iron ring 3 in the joint inboard of shotcrete pipe 2, and nexine iron ring 3 is embedding
Enter on the inwall at described shotcrete pipe joint 2, fix with described shotcrete pipe and be connected.Shotcrete pipe 2 is stuck in outer layer iron ring 1 and nexine
Between iron ring 3 two-layer iron ring, such Gunning material would not be ground away the flexible pipe of joint, reduces the risk of shotcrete pipe blocking.
