Description

Technical Field

[0001] The utility model relates to the technical field of concrete anti-corrosion testing, in particular to a concrete anti-corrosion testing device. Background Art

[0002] Concrete is one of the main building materials in contemporary times. It is an artificial stone made of cementitious materials, aggregates, water, admixtures and admixtures in a certain proportion, which is evenly mixed, compacted and hardened. Concrete has the characteristics of abundant raw materials, low price and simple production process, so its usage is increasing. Concrete may suffer from corrosion during long-term use, affecting the service life and safety of the building. Therefore, before using concrete, the anti-corrosion performance of concrete needs to be tested by anti-corrosion testing equipment.

[0003] For example, a building concrete anti-corrosion testing device disclosed in the existing patent application number CN202322396748.5, when taking out the tested concrete from the inside of the test box, the building concrete anti-corrosion testing device can move the concrete clamped at the bottom of the adjustment plate out of the test box to avoid directly scooping out the liquid inside the concrete with high corrosiveness and causing damage. However, due to the lack of an effective locking and limiting structure on the rotating wheel used to reel in the corrosion-resistant rope, when the motor driving the rotating wheel suddenly loses power during operation, the clamping mechanism and the concrete will fall rapidly downward, causing the corrosive liquid inside the test box to splash onto the operator, thereby reducing the safety during the test work. Moreover, although a water outlet is provided on the test box, and a valve is installed on the water outlet, the corrosive liquid inside the test box can be discharged by opening the valve on the water outlet. However, the test box that has been used for a long time is prone to be mixed with a large amount of concrete debris, which can easily cause the valve on the water outlet to be blocked, causing trouble for the drainage work.

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings of the embodiment of the utility model.

The corrosion-resistant rope 504 passes through the rectangular through-hole 104 and is slidably connected to the two guide pulleys 105. The lower end of the corrosion-resistant rope 504 is fixedly connected to the C-shaped driving frame 507; the lifting plate 505 is slidably connected to the outside of the four vertical support rods 101, and the upper surface of the lifting plate 505 is fixedly connected to the C-shaped driving frame 507; the rotating shaft of the rotating wheel 503 is fixedly connected to the rotating wheel 503, and a worm gear 506 meshing with the worm 502 is fixedly installed at the right end of the rotating shaft of the rotating wheel 503; a rectangular sliding opening is formed in the middle of the upper surface of the lifting plate 505; the developed helix angle of the worm 502 is smaller than the friction angle in contact with the worm gear 506, so that the worm gear 506 and the worm 502 can obtain an effective self-locking effect. Therefore, even if a sudden power failure occurs during the operation of the lifting motor 501, the clamping mechanism 3 and the concrete block 4 will not quickly fall downward.

[0038] The clamping mechanism 3 includes stainless steel clamping plates 301, clamping screws 302, sliding cylinders 303, transverse guide rods 304, nuts 305, and an adjustment motor 306. The number of stainless steel clamping plates 301 is two, and the two stainless steel clamping plates 301 are slidably connected inside the rectangular sliding opening formed in the middle of the upper surface of the lifting plate 505, and corrosion-resistant anti-slip rubber sheets are provided on the opposite surfaces of the two stainless steel clamping plates 301; a sliding cylinder 303 is fixedly connected to the upper part of the front and rear sides of each stainless steel clamping plate 301, and a nut 305 is fixedly installed on the upper end of each stainless steel clamping plate 301; the number of transverse guide rods 304 is two, and the two transverse guide rods 304 are respectively fixedly connected to the front and rear sides of the bottom end surface of the lifting plate 505, and the two transverse guide rods 304 are respectively slidably connected to the four sliding cylinders 303; the clamping screw 302 is rotatably connected to the upper surface of the lifting plate 505, and two reverse threads are symmetrically arranged on the outside of the clamping screw 302, and the outside of the clamping screw 302 is respectively connected to the two nuts 305 through the two reverse threads; a driven pulley is fixedly installed at the left end of the clamping screw 302, the adjustment motor 306 is installed on the upper surface of the lifting plate 505, and a driving pulley is fixedly installed on the rotating shaft of the adjustment motor 306, and the driving pulley is传动连接 to the driven pulley through a belt; through the setting of the clamping mechanism 3, it is used to clamp the concrete block 4.

[0039] Embodiment 2, on the basis of Embodiment 1, such as Figure 5 and Figure 6As shown, a water outlet 204 is provided at the lower part of the right end surface of the test box 2, and a corrosion-resistant hose 205 is connected to the right end of the water outlet 204, and an L-shaped metal plate 206 is fixedly connected to the outside of the discharge end of the corrosion-resistant hose 205; a plug-in sleeve 207 is fixedly connected to the upper part of the right end surface of the test box 2, and a magnetic strip 208 is fixedly connected to the upper part of the right end surface of the plug-in sleeve 207, which can be magnetically attracted to the L-shaped metal plate 206.

[0040] When the L-shaped metal plate 206 is inserted into the inserting sleeve 207 , the right bottom end surface of the L-shaped metal plate 206 is magnetically attracted to the magnetic strip 208 , so that the L-shaped metal plate 206 can be effectively limited on the inserting sleeve 207 .

[0041] The working principle of this embodiment is as follows: when in use, the corrosive liquid is filled into the test box 2, and then the concrete block 4 to be tested is clamped between the two stainless steel clamping plates 301, and then the lifting motor 501 is started and the rotating shaft of the lifting motor 501 is controlled to reverse, thereby causing the worm 502 to reverse. At this time, the worm gear 506 drives the rotating wheel 503 to rotate counterclockwise, so that the lower end of the corrosion-resistant rope 504 wrapped around the rotating wheel 503 begins to move downward. At this time, the lifting plate 505, the clamping mechanism 3 and the concrete block 4 move downward in a straight line under the action of gravity, so that the concrete block 4 is immersed in the corrosive liquid, and the corrosion resistance of the concrete block 4 is tested.

[0042] When the corrosion resistance test of the concrete block 4 is completed and the concrete block 4 needs to be taken out, the rotating shaft of the lifting motor 501 is controlled to rotate forward, thereby driving the worm 502 to rotate forward. At this time, the worm wheel 506 drives the rotating wheel 503 to rotate clockwise, thereby winding the corrosion-resistant rope 504, so that the lower end of the corrosion-resistant rope 504 moves upward in a straight line with the lifting plate 505, the clamping mechanism 3 and the concrete block 4, thereby bringing the concrete block 4 out of the corrosive liquid, and then the concrete block 4 is removed from the clamping mechanism 3. Since the unfolded helix angle of the worm 502 is smaller than the friction angle of contact with the worm wheel 506, the worm wheel 506 and the worm 502 can obtain an effective self-locking effect, so that when the lifting motor 501 is in operation, even if there is a sudden power failure, the clamping mechanism 3 and the concrete block 4 will not fall down rapidly, thereby avoiding the phenomenon that the corrosive liquid inside the test box 2 splashes onto the operator.

[0043] When the waste corrosive liquid in the test box 2 needs to be discharged, the L-shaped metal plate 206 is simply removed from the plug-in sleeve 207 to make the drainage end of the corrosion-resistant hose 205 lose its limiting effect, and then the corrosion-resistant hose 205 is straightened horizontally to discharge the waste corrosive liquid in the test box 2.
