Description

Technical Field

[0001] This invention relates to the technical field of crack inhibitors and their production equipment, and in particular to a VF crack inhibitor and its production equipment. Background Technology

[0002] During the construction process, the integrity of the concrete panels, especially the top surface, must be ensured. When cracks appear in the panels, it will affect the sealing of the overall structure, making project acceptance difficult and requiring frequent repairs in subsequent use.

[0003] Depending on the cause of the cracks, panel cracks can be divided into structural cracks and non-structural cracks.

[0004] Cracks are classified into two types;

[0005] Structural cracks in the panel are cracks generated under external forces. The main cause of these cracks is the uneven settlement and horizontal displacement of the rockfill dam panel support (dam body) under its own weight and water pressure, leading to a gap between the panel and the subbase, which alters the panel's compressive mechanical properties and causes cracks. Non-structural cracks in the panel are cracks generated without external forces. According to statistics, 80% of panel cracks are non-structural cracks. There are many causes of non-structural cracks in the panel, which can be mainly divided into: (1) cracks caused by improper construction of the panel concrete; (2) cracks caused by chemical reactions of the panel concrete materials; and (3) cracks caused by shrinkage of the panel concrete.

[0006] To eliminate non-structural cracks in the panels, crack-resistant agents are needed to eliminate cracks caused by concrete shrinkage.

[0007] The crack-resistant agent is composed of a mixture of multiple components. During mixing, the proportion of components needs to be adjusted according to various conditions such as panel composition, climate, and geographical environment. Therefore, this application proposes a production equipment that can adjust the proportion of crack-resistant agent components at any time to facilitate on-site construction.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments: See also Figures 1-7 A crack-resistant agent production equipment includes a main frame 1, a turntable 2, and a plurality of storage bins 3 disposed on the turntable 2. The storage bins 3 are evenly and fixedly distributed on the turntable 2, and their number corresponds to the number of components of the crack-resistant agent. That is, the storage bins 3 are used to store the components of the crack-resistant agent, and each storage bin 3 corresponds to one component.

[0036] The main frame 1 is equipped with a cam divider 101 that cooperates with the turntable 2. The turntable 2 is fixed to the output shaft end of the cam divider 101. The rotation angle of the cam divider 101 in one drive can be adjusted according to the number of storage bins 3. The bottom of the storage bins 3 is provided with a discharge port. The lower end surface of the turntable 2 is provided with an opening plate 201 that cooperates with the discharge port. Specifically, as shown... Figure 5 As shown, the door opening plate 201 is provided with a drive rod 203 extending to one side, and the turntable 2 is provided with a door opening cylinder 202 connected to the end of the drive rod 203. The drive rod 203 is rotatably mounted on the turntable 2. When the drive rod 203 rotates, it can move the door opening plate 201 away from or closer to the discharge port, thereby realizing the opening or closing of the discharge port of the storage tank 3.

[0037] The push rod end of the door opening cylinder 202 is provided with a connecting rod connected to the drive rod 203. One end of the connecting rod is fixed to the end of the push rod, and the other end is rotatably mounted on the drive rod 203. The drive rod 203 is provided with a rotating hole that cooperates with the connecting rod. That is, the door opening cylinder 202 can realize the control of the door opening plate 201, and further realize the opening or closing of the bottom opening of the storage bucket 3.

[0038] The main frame 1 is equipped with a weighing station 4. After the turntable 2 is driven by the cam divider 101 to an angle, the weighing station 4 can be matched with a corresponding component storage bin 3. Then, the door opening cylinder 202 opens the door plate 201, allowing the corresponding component to fall into the weighing station 4.

[0039] like Figure 4 As shown, the weighing station 4 includes a weighing bucket 401, several weighing blocks 403 connected to the weighing bucket 401 by a pull rope 402, and an adjusting and locking block 404 that cooperates with the weighing blocks 403. A pulley frame 103 is fixed on the main frame 1. Several pulleys 406 that cooperate with the pull rope 402 are provided on the pulley frame 103. The center of the weighing bucket 401 corresponds to the center of the rotating storage bucket 3. One end of the pull rope 402 is fixedly connected to the support rod on the weighing bucket 401, and the other end is fixedly provided with a limiting block 408 after passing over the pulley 406. The weighing blocks 403 are placed on the limiting block 408 in sequence, and the pull rope 402 passes through the central hole of the limiting block 408.

[0040] The pulley frame 103 is fixedly provided with a linear module 405 that cooperates with the weighing block 403 on the side near the weighing block 403. A slider that can be driven by the module is slidably mounted on the linear module 405. The adjusting locking block 404 is fixed on the slider. The adjusting locking block 404 is preferably an electromagnetic block, that is, it can attract the weighing block 403 after being energized. Initially, the adjusting locking block 404 is in the lowest position, at which time it is attracted to the lowest weighing block 403. Figure 3As shown, the weight of the empty weighing bucket 401 on the left is equivalent to that of the limiting block 408, and the two sides are in a balanced state. A reset cylinder 410 is provided below the limiting block 408 to reset it. When the weighing station 4 is not working, the cylinder 410 presses against the limiting block 408 to keep it in a balanced state. Figure 3 The location shown.

[0041] The linear module 405 is equipped with a limiting plate 409 at its upper end, which cooperates with the uppermost weighing block 403. At this time, the upper and lower ends of several weighing blocks 403 are restricted by the adjusting locking block 404 and the limiting plate 409 and cannot move. When the material in the storage hopper 3 falls into the weighing hopper 401, a signal is given to the linear module 405 to slide the adjusting locking block 404 to the corresponding position and lock the weighing block 403 at that position. Then, the reset cylinder 410 descends, and the weighing block below the corresponding weighing block 403 presses down the limiting block 408 under the action of gravity, pulling the pull rope 402 to raise the weighing hopper 401. When the weight of the material in the weighing hopper 401 reaches the same as the weighing block falling on the right, the weighing hopper 401 is lowered back to the initial position to complete the weighing, and a signal is given to the door opening cylinder 202 to close the door opening plate 201.

[0042] To enable real-time adjustment of the material ratio of different components, a vertically mounted damping rod 302 is fixed on the outer wall of the storage tank 3. The damping rod 302 is located on the outer wall away from the center of the turntable 2. The damping rod 302 is preferably a hexagonal rod. A damping adjustment block 301 is provided on the damping rod 302. The damping adjustment block 301 can slide on the damping rod 302, that is, the damping adjustment block 301 can stop at any height position of the damping rod 302 without falling. The operator can adjust the damping adjustment block 301 by moving it. Preferably, a scale line can be marked on one side of the damping rod 302 to enable the operator to make precise adjustments to the damping adjustment block 301.

[0043] The main frame 1 is equipped with a button lever 102, which is located on the side of the weighing barrel 401 away from the center of the turntable 2, as shown in the figure. The upper end of the button lever 102 is equipped with several adjustment buttons 407 that cooperate with the sliding damping adjustment block 301. That is, when the damping adjustment block 301 is adjusted to different heights, different adjustment buttons 407 can be triggered. The adjustment buttons 407 are coupled with the linear module 405. The adjustment buttons 407 at different heights can trigger the linear module 405 to move the slider to different heights. Preferably, the higher the height of the adjustment button 407, the higher the height of the slider, so that the position of the weighing block 403 locked by the adjustment locking block 404 is higher. That is, the heavier the material weighed in the weighing barrel 401 needs to be to match the unlocked weighing block on the right.

[0044] The weighing barrel 401 is provided with a liftable unloading plate 501 at its bottom, and the upper surface of the unloading plate 501 is preferably a unloading cone surface 502, such as... Figure 3 and Figure 7 As shown, when the discharge plate 501 slides down and opens, the material in the weighing barrel 401 can slide out of the weighing barrel 401 through the discharge cone surface 502. A discharge pipe is provided below the weighing barrel 401, and the discharge pipe can be connected to a stirrer, so that the various components after batching fall into the stirrer for mixing.

[0045] The unloading plate 501 is fixed with symmetrically arranged guide rods 505 on both sides. The guide rods 505 pass through the mounting plate at the bottom of the weighing barrel 401 and are fixed with a stop plate 506. An electromagnet 503 is fixed on the mounting plate at the bottom of the weighing barrel 401 facing the unloading plate 501. A magnetic suction plate 504 that can attract the electromagnet 503 is fixed in the middle of the guide rod 505. When the electromagnet 503 is energized, it can attract the magnetic suction plate 504. At this time, the unloading plate 501 slides upward to close the outlet of the weighing barrel 401. When the electromagnet 503 is de-energized, the unloading plate 501 slides downward due to its own weight to open the outlet of the weighing barrel 401.

[0046] The main frame 1 is equipped with a first switch 507 coupled to an electromagnet 503, and the weighing tank 401 is equipped with a contact plate 508 that can trigger the first switch 507. The first switch 507 can also preferably be located at, for example,... Figure 6 On the left side of the pulley frame 103 shown, when the contact plate 508 contacts the first switch 507, the electromagnet 503 can be de-energized to open the unloading plate 501 for unloading.

[0047] In this embodiment, the above-mentioned electrical components can be programmed in series by a PLC controller or a microcontroller to achieve automatic batching.

[0048] The VF crack-resistant agent produced using the aforementioned crack-resistant agent production equipment comprises gypsum, alum stone powder, high-alumina cement, fly ash, and clinker. The component content of the gypsum, alum stone powder, high-alumina cement, fly ash, and clinker is in the following weight ratio: 30~50: 5~15: 5~10: 5~10: 10~25. The gypsum, alum stone powder, high-alumina cement, fly ash, and clinker can be sequentially placed into the storage tank 3. Subsequently, the operator can adjust the height of the damping adjustment block 301 of the corresponding storage tank 3 according to the actual mixing ratio requirements.

[0049] The method for preparing VF crack inhibitor using the aforementioned anti-cracking agent production equipment is as follows: When using, place the five components of the VF crack inhibitor into five storage containers 3, as follows: Figure 1 As shown, the damping adjustment blocks 301 on each component storage tank 3 are then adjusted to the corresponding proportional height, and the equipment is then started.

[0050] After the damping adjustment block 301 of any storage hopper 3 rotates to the weighing station 4, the corresponding adjustment button 407 is triggered, causing the linear module 405 to drive the adjustment locking block 404 to the corresponding height position to lock the weighing block 403 at that position. Then the reset cylinder 410 descends, and the unlocked weighing block 403 drives the pull rope 402 to raise the weighing hopper 401. The unloading plate 501 at the bottom of the weighing hopper 401 is attracted by the electromagnet 503 and closes the discharge port.

[0051] Subsequently, the door-opening cylinder 202 at the bottom of the storage bin 3 corresponding to the weighing station 4 opens, allowing the material to fall into the weighing bin 401. As the material mass gradually increases, the pull rope 402 is pulled to raise the right limit block 408 until it is balanced. At this time, the first switch 507 contacts the contact plate 508. Simultaneously, the door-opening cylinder 202 closes, and the reset cylinder 410 rises to push the limit block 408 back against the ground. The first switch 507 triggers the electromagnet 503 to de-energize, opening the unloading plate 501 to unload the material. The components in the weighing bin 401 then fall into the discharge pipe and enter the agitator. Then, the cam divider 101 rotates again, repeating the above actions to weigh and dispense the next component.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
