Background technology
Concrete permeability test is the routine test of detection concrete Penetration Signature in hydraulic engineering.Examination used in test
Part 9 is generally truncated cone-shaped (outer circumference surface of test specimen needs to contact with die trial), before the test will be beforehand through manual type in examination
Certain thickness encapsulant (encapsulant is formed by paraffin and rosin proportioning) is coated on part surface, and its process is：First by solid-state
Encapsulant be put into molten basin (roller coating basin) in and be melted to liquid with heating by electric cooker, then test specimen be put in molten basin constantly roll
Roller coating is carried out, loads die trial after the encapsulant thickness covered on test specimen meets requirement.
But the rolling process depends on the operating experience of workman, also has the following disadvantages：
(1) temperature of encapsulant cannot be accurately controlled when heating, the adhesiving effect of encapsulant is easily affected；
(2) velocity of rotation of test specimen cannot be accurately controlled during roller coating, the encapsulant mistake being covered on test specimen is easily caused
It is thick or excessively thin；
(3) it is difficult to grasp the liquid level of encapsulant in molten basin, test specimen immerses in encapsulant too far and easily affects
Test；
(4) per group of test will typically use 6 test specimens and each test specimen about 5kg or so, and labour intensity is larger；
(5) success rate of roller coating is relatively low, and easily causing test specimen cannot load in die trial, therefore operating efficiency lowly (has Jing
Test workman roller coating success rate about 50～60% and rawness workman roller coating success rate less than 30%).

Moving axis is driven by transmission component, is fixed in frame parallel to the driven axle of driven shaft；It is fixed with driven shaft for supporting
Test specimen and drive test specimen rotate driving wheel, be rotatably positioned on driven axle for support test specimen and coordinate test specimen rotate
Follower；
The elevating mechanism includes the lifting motor being arranged on outside molten basin, for transmitting motor power to promote frame to swing
Leading screw group, connection motor and leading screw group cross hinge and connection frame and screw mandrel group connecting plate.
The frame is to be arranged with two parting beads in parallel in rectangular frame and rectangular frame.
The nut of the leading screw group can be swingingly positioned on connecting plate around horizontal axis by jointed shaft, jointed shaft axis
Parallel with the axis of oscillation of frame, the screw rod of the leading screw group is passed sequentially through cross hinge and is connected with adapter sleeve with machine shaft,
Three wheel faces that described each driving wheel is sequentially reduced including diameter with follower.
The heater is electrothermal tube.
The invention has the beneficial effects as follows：
The present invention is for the test specimen roller coating encapsulant in concrete permeability test；Only need to by encapsulant (paraffin and
Rosin) it is put in molten basin by a certain percentage and the test specimen for needing roller coating is placed in frame, test specimen is adjusted by elevating mechanism then
Contact depth with liquid sealing material, then constantly rotation completes roller coating to drive test specimen by rolling mechanism；The present invention can have
In the case of effect control test specimen immersion depth, it is ensured that encapsulant is equably covered on test specimen and controls sealing material exactly
The thickness of material, completely eliminates the impact of human factor so that the die-filling success rate of test specimen reaches more than 90%, significantly reduces
The working strength and workload of testing crew, has been significantly increased operating efficiency.
