Description

Technical Field

[0001] The invention relates to the technical field of concrete test molds, in particular to an automatic oiling concrete test mold device. Background Art

[0002] The concrete test mold is used to make test pieces for testing the mechanical properties of concrete and its long-term and durability tests. In order to ensure that the concrete can be separated from the mold smoothly during demolding and to keep the concrete shape intact and the mold intact, it is necessary to brush oil on the inner wall surface of the test mold, apply engine oil or a release agent before making the concrete mold.

[0003] In the prior art, when brushing oil on the inner wall of the test mold, a person usually holds a brush by hand, dips the brush head into oil, and then inserts the brush head dipped in oil into the inside of the test mold for brushing.

[0018] (III) Beneficial effects

[0019] Compared with the prior art, the present invention provides a concrete mold test device with automatic oiling, which has the following beneficial effects:

[0020] 1. The automatic oiling concrete mold test device drives the brush head down through the lifting electric cylinder, so that the brush head is inserted into the mold groove. Under the action of two metering pumps, the same amount of oil is input into two delivery branches through the bellows, and then injected into the oil filling grooves respectively. The oil in the oil filling grooves seeps out from the oil outlet holes on the surface, and the seeped oil is absorbed by the elastic oil brush layer. The oil absorbed by the elastic oil brush layer contacts the inner wall of the mold groove and is evenly smeared on the inner wall surfaces of the two side-by-side mold grooves. Then, the brush head is driven up by the lifting electric cylinder to complete the oiling of the two mold grooves. The degree of automation is high, and the oiling operation can be completed conveniently and quickly.

[0021] 2. The automatic oiling concrete test mold device limits the test molds closely arranged in two rows through the first limiting mechanism and the second limiting mechanism. Shaking the first crank handle and the second crank handle can respectively drive the first limiting plate and the second limiting plate to move, and fix two sides of the test mold. Under the limiting action of the first limiting plate and the second protective edge on one side, and the second limiting plate and the first protective edge on one side, the four sides of different numbers of test molds can be limited. The device has high practicality and can effectively prevent the test mold from moving during the oiling process to avoid affecting the oiling operation.

[0022] 3. The automatic oiling concrete test mold device drives the table to vibrate through the vibration source inside the base. The test mold filled with concrete vibrates, and the tiny bubbles in the concrete are effectively eliminated, making the concrete blocks more compact. During vibration, the neatly arranged test molds are freely dispersed, and the first and second protective edges on the four sides of the table limit them to prevent the test molds from falling during the vibration process.

[0035] Furthermore, the vibration table 1 includes a base 11, a table top 12, a first protective edge 13, and a second protective edge 14.

[0036] Furthermore, the first limiting mechanism 6 includes a first limiting plate 61, a first sliding block 62, a first screw 63, a first crank 64 and a first pulley 65. The lower surface of the first limiting plate 61 is in contact with the surface of the table 12. The first sliding block 62 and the first pulley 65 are slidably installed in the first limiting groove 131 and the first slide groove 132 respectively. The first screw 63 is connected to the first sliding block 62 by a thread, so that the first screw 63 is driven to rotate by shaking the first crank 64, so that the first sliding block 62 slides along the inner wall of the first limiting groove 131, and then drives the first limiting plate 61 to move. The first pulley 65 rolls in the first slide groove 132 to make the first limiting plate 61 more convenient to move. When the oil brushing mechanism 4 brushes oil on the mold groove 21, the first limiting plate 61 and the second protective edge 14 on one side are used to limit the test mold 2 closely arranged in two rows to prevent the test mold 2 from moving during the oil brushing process and affecting the oil brushing effect.

[0037] The second limit stop 71 of the embodiment of the present invention is a plurality of first limit stop assemblies 71, a plurality of second limit stop assemblies 72 are assembled, and the plurality of second limit stop assemblies 72 are assembled together, and the plurality of second limit stop assemblies 72 are assembled together, and the plurality of second limit stop assemblies 72 are assembled together.

The electric slider 441 is slidably connected to the electric slide rail 31, so that the oil brushing mechanism 4 can slide on the upper end of the trial mold 2. When the brush head 41 slides to just above the mold groove 21, the brush head 41 is driven down by the lifting electric cylinder 43, so that the brush head 41 can penetrate into the mold groove 21 for brushing oil.

[0040] Working principle: when in use, the clean test molds 2 are neatly arranged in two rows and placed on the surface of the table 12, and the first crank handle 64 is shaken to drive the first screw rod 63 to rotate, so that the first sliding block 62 slides along the inner wall of the first limiting groove 131, thereby driving the first limiting plate 61 to move to one side of the test mold 2; then the second crank handle 74 is shaken to drive the second screw rod 73 to rotate, so that the second sliding block 72 slides along the inner wall of the second limiting groove 141, thereby driving the second limiting plate 71 to move to one side of the test mold 2. During the movement, the first limiting plate 61 and the second limiting plate 71 slide relative to each other without interfering with each other in the movement process. Under the limiting action of the first limiting plate 61 and the second protective edge 14 on one side, and the second limiting plate 71 and the first protective edge 13 on one side, the four sides of different numbers of test molds 2 can be limited, which is highly practical and can effectively prevent the test mold 2 from moving during the oiling process to avoid affecting the oiling operation;

[0041] The support frame 3 is moved to the specified position by the roller 32, and the support frame 3 is fixed to the center line of the vibration table 1 by the detachable positioning piece 15. With the cooperation of the electric slider 441 and the electric slide rail 31, the oil brushing mechanism 4 can slide on the upper end of the test mold 2, and the brush head 41 stops when it slides to the top of the mold groove 21. The connecting frame 42 is driven down by the lifting cylinder 43, and then the brush head 41 is driven down, so that the brush head 41 is probed into the mold groove 21. At the same time, under the action of the two quantitative pumps 533, the same amount of oil is input into the two delivery branches 532 through the bellows 52, and then The oil is injected into the oil filling groove 412 respectively, and the oil in the oil filling groove 412 seeps out from the oil outlet hole on the surface, and then is smeared on the inner wall surfaces of the two side-by-side mold grooves 21 respectively through the adsorption of the elastic brush oil layer 413. After the two mold grooves 21 are brushed with oil, the brush head 41 is driven to rise by the lifting cylinder 43; the electric slider 441 continues to drive the brush head 41 to move to the top of the next row of mold grooves 21, and the above-mentioned brushing operation is repeated until the mold grooves 21 of all the trial molds 2 are brushed with oil, and the support frame 3 is released by the detachable positioning member 15, and the support frame 3 is removed to avoid affecting the subsequent operation;

[0042] Fill the mold groove 21 of the test mold 2 that has been oiled with concrete that needs to be tested, and then shake the first crank 64 and the second crank 74 respectively to drive the first limit plate 61 and the second limit plate 71 to move to the edge position respectively, release the limit, and drive the table 12 to vibrate through the vibration source inside the base 11, so that the test mold 2 filled with concrete vibrates, and the tiny bubbles in the concrete are effectively eliminated, making the concrete blocks more dense, and the neatly arranged test molds 2 are freely dispersed by vibration, and the first protective edge 13 and the second protective edge 14 limit them to prevent the test mold 2 from falling during the vibration process.
