Description
Technical field
It the utility model is related to spiral duct tightness testing device, specially spiral duct bulge test machine.
Background technology
The spiral duct that colliery is used to draw out methane is before use, seal test need to be carried out, it is ensured that its own body
Side wall will not be revealed under certain malleation and negative pressure condition.At present, this test utilizes blind plate to spiral duct by worker
Both ends are sealed, and to being inflated in spiral duct, so as to test the seal of spiral duct.Such a method worker work
Intensity is very big, and operating efficiency is low, and not only the test of spiral duct seal is not accurate enough, and safety easily occurs in test
Accident.Therefore, design that a kind of can to utilize automation equipment be that extremely have must to the device of spiral duct progress seal test
Want.
The content of the invention
The utility model solves to lack spiral duct bulge test machine at present, causes that manual test labor intensity is big, work
Efficiency is low, quality can not ensure, and the unsafe problem of test process, there is provided a kind of spiral duct bulge test machine.
The utility model is achieved through the following technical solutions：Spiral duct bulge test machine, including Rectangular Water Trough, institute
The support for being provided with tank and being driven vertically by hydraulic cylinder is stated, described support one end is vertically arranged with fixing seal plate, described solid
Determine to be sealedly connected with air compressor machine and vavuum pump on sealing plate, the support other end is fixed with horizontally disposed compressed oil cylinder, institute
State compressed oil cylinder termination and be fixed with compression sealing plate.Spiral duct is placed on support, and a termination is supported on fixing seal plate,
The compression sealing plate that the other end is driven by compressed oil cylinder compresses, true to suppressing or taking out in spiral duct by air compressor machine or vavuum pump
It is empty.Driven by Hydraulic Cylinder support rises emersion tank.
The support bottom is provided with least two groups to heart roller, the installation position to heart roller along stent length direction
Put and be engaged with diameter with the diameter of the connection hole position and spiral duct of air compressor machine on fixing seal plate and vavuum pump.The heart is rolled
The sustainable spiral duct of wheel, and play a part of positioning to the heart, it is ensured that the clamped position face fixing seal plate of spiral duct
The connection hole position of upper air compressor machine and vavuum pump.Fluid sealant is fixed with the fixing seal plate one side relative with sealing plate is compressed
Pad.Seal gasket ensures that sealing is tight reliable.
The utility model has advantages below：1st, it is simple in construction, it is easy to operate；2nd, sealing is tight, is grasped manually without worker
Make；3rd, labor intensity substantially reduces, and operating efficiency improves；4th, seal test result is intuitively visible；5th, it is safe；6th, install
It is fast and accurate for positioning.
Brief description of the drawings
Fig. 1 is the utility model structural front view；
Fig. 2 is Fig. 1 top views；
In figure：1- tanks, 2- hydraulic cylinders, 3- supports, 4- fixing seal plates, 5- compressed oil cylinders, 6- compression sealing plates, 7- pairs

Embodiment
Spiral duct bulge test machine, including Rectangular Water Trough 1, it is provided with what is driven vertically by hydraulic cylinder 2 in the tank 1
Support 3, described one end of support 3 are vertically arranged with fixing seal plate 4, be sealedly connected with the fixing seal plate 4 air compressor machine and
Vavuum pump, the other end of support 3 are fixed with horizontally disposed compressed oil cylinder 5, and it is close that the termination of compressed oil cylinder 5 is fixed with compression
Shrouding 6.
When it is implemented, the bottom of support 3 is provided with least two groups to heart roller 7 along the length direction of support 3, it is described right
The installation site and diameter of heart roller 7 and the connection hole position and spiral duct of air compressor machine and vavuum pump on fixing seal plate 4
Diameter is engaged.Seal gasket is fixed with the fixing seal plate 4 one side relative with sealing plate 6 is compressed.
In use, water will be full of in tank 1, manipulate hydraulic cylinder 2 and hold up support 3, placed tested spiral duct with crane
In the bottom of support 3 on heart roller 7, a termination of spiral duct is alignd with fixing seal plate 4, manipulate compressed oil cylinder 5 and drive
The other end that sealing plate 6 compresses spiral duct is compressed, ensures that the both ends of spiral duct compress with the seal gasket on sealing plate
Sealing.Then manipulate hydraulic cylinder 2 to fall, spiral duct is immersed in below the liquid level of tank 1 completely.By air compressor machine to spiral duct
Inside it is inflated to specified air pressure, observes to whether there is gas leakage bubble in tank under liquid level and produce and can determine whether that spiral duct is close under positive air pressure
Whether closing property is qualified.Conversely, by the gas in vacuum pump depletion spiral duct to specified negative pressure, observation spiral duct side wall has
Nothing collapses, you can judges whether seal of the spiral duct in the case where specifying negative pressure be qualified.
