Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for concrete testing, specifically a mobile automatic molding device for concrete test blocks. Background Technology

[0002] Concrete test blocks are standard specimens used to test the performance of concrete. Traditional concrete test block molding equipment mostly adopts manual molding methods, such as manual shoveling and vibration molding.

[0003] In large-scale projects, there are many batches of concrete to be mixed daily and the pouring points are scattered. Manual molding and tamping usually require 4-6 people to operate simultaneously. The concrete needs to be collected manually into the test block mold, which is labor-intensive and inefficient. In contrast, the existing automatic molding equipment places the test block mold directly on the support plate of the vibratory molding equipment. The vibratory molding equipment drives the support plate to vibrate through a vibrating motor, which removes air bubbles from the cement sample.

[0004] However, existing automatic concrete block forming equipment does not position the block mold. During the process of forming the block using vibration, the block mold is prone to displacement or collision, which can cause a large amount of cement to overflow.

[0005] Furthermore, during the process of molding test blocks through vibration, cement overflows from the test block mold and falls onto the placement plate of the test block mold. The placement plate cannot be disassembled, and the overflowing mud can only be shoveled out with tools. Often, the cleaning is not thorough, causing inconvenience and material waste. The cement solidifies on the placement plate for a long time, affecting the subsequent placement of the test block mold for molding.

[0006] Based on this, the present invention provides a mobile automatic concrete test block molding device to solve the above problems. Utility Model Content

[0007] In view of the above situation and to overcome the defects of the prior art, this utility model provides a movable automatic concrete test block molding device. This utility model has a novel structure and ingenious design, and effectively solves the technical problems of being unable to position the test block mold and the inconvenience of quickly cleaning up spilled cement.

[0008] A movable concrete test block automatic molding device includes a movable base and a supporting spring. A snap-fit ​​assembly is fixedly connected to the top of the supporting spring. The snap-fit ​​assembly includes a fixed seat. A vibration motor is fixedly installed at the bottom of the fixed seat. An installation seat is detachably connected to the top of the fixed seat. Two first slots are opened at the bottom of the installation seat. Two locking shells are fixedly connected to the bottom of the fixed seat. Trapezoidal locking blocks are slidably connected inside the two locking shells. Pull rods are fixedly connected to the bottom of the two trapezoidal locking blocks. A return spring is sleeved on the two pull rods. One end of the two pull rods slides through the locking shells and is fixedly connected to the same pull plate. A surrounding plate, four right-angle positioning plates, and two arc-shaped positioning plates are fixedly connected to the top of the installation seat.

[0009] Preferably, the two trapezoidal blocks are respectively engaged in the two first slots, and the inner walls of the four right-angle positioning plates are overlapped with the same square test block mold.

[0010] Preferably, a U-shaped seat is fixedly connected to the top of the pull plate, a rotating shaft is rotatably connected to the inner wall of the U-shaped seat, a convex plate is fixedly connected to the surface of the rotating shaft, and a rotating handle is fixedly connected to one end of the rotating shaft. An arc-shaped groove is provided at the bottom of the fixed seat, and one end of the convex plate can be engaged in the arc-shaped groove.

[0011] Preferably, the movable base includes a base shell and a lifting plate. Two synchronous electro-hydraulic push rods are fixedly connected to the top of the lifting plate, and the output ends of the two synchronous electro-hydraulic push rods are fixedly connected to the inner wall of the base shell. Universal wheels are fixedly connected to the bottom of the lifting plate.

[0012] Preferably, both ends of the support spring are fixedly connected to the top of the bottom shell and the bottom of the fixed base through connecting seats, and the bottom of the bottom shell has four through holes corresponding to the positions of the four universal wheels.

[0013] Preferably, a push handle is fixedly connected to one side of the bottom shell, and a handle is fixedly connected to one side of the mounting base.

[0014] The present invention has the following technical effects.

[0015] 1. This utility model uses a structure that combines right-angle positioning plates, arc-shaped positioning plates, and mounting bases. When the vibrating motor is working, the four right-angle positioning plates or two arc-shaped positioning plates limit the square or round test block mold. This eliminates the need for manual fixing of the mold and achieves positioning of the square or round test block mold. It also prevents the mold from shifting, colliding, or tipping over during the operation of the vibrating motor, thereby preventing excessive cement spillage and reducing material waste.

[0016] 2. This utility model uses a pull-down plate to drive the trapezoidal locking block to disengage from the first locking groove, and rotates the rotating handle to make the convex plate lock into the arc-shaped locking groove, thereby pulling the mounting base out of the fixed base, realizing quick disassembly of the mounting base, which can facilitate the cleaning of spilled cement and reduce maintenance difficulty.

Detailed Implementation

[0024] The foregoing and other technical contents, features and effects of this utility model are described in conjunction with the appendix below. Figures 1 to 5 The detailed description of the embodiments will make this clear. All references to the following embodiments are made with reference to the accompanying drawings.

[0025] Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings.

[0026] This utility model is a mobile automatic concrete test block molding equipment. Existing automatic concrete test block molding equipment has many problems: First, it lacks the test block mold positioning function, and the mold is prone to displacement and collision during vibration molding, causing cement to overflow; Second, the cement overflowing during vibration will fall onto the placement plate, and the placement plate cannot be disassembled, reducing cleaning efficiency.

[0027] For automated molding equipment, it is impossible to position the test block mold, and the mounting base cannot be disassembled, making it inconvenient to quickly clean the table surface.

[0028] As an example, such as Figures 1-3 As shown, this utility model includes a movable base 1 and a support spring 2. A snap-fit ​​assembly 3 is fixedly connected to the top of the support spring 2. The snap-fit ​​assembly 3 includes a fixed seat 301. A vibration motor 10 is fixedly installed at the bottom of the fixed seat 301. A mounting seat 4 is detachably connected to the top of the fixed seat 301. The mounting seat 4 is a pull-out type and cannot be removed from the top. One side of the fixed seat 301 is closed, which can limit one side of the mounting seat 4. Two first slots 5 are opened at the bottom of the mounting seat 4. Two retaining shells 302 are fixedly connected to the bottom of the fixed seat 301. The positions of the two retaining shells 302 correspond to the positions of the two first slots 5. The inner of the two retaining shells 302... Each part is slidably connected with a trapezoidal locking block 303. The bottom of each trapezoidal locking block 303 is fixedly connected with a pull rod 304. Each pull rod 304 is sleeved with a return spring 305. One end of the return spring 305 is fixedly connected to the inner wall of the housing 302, and the other end of the return spring 305 is fixedly connected to the bottom of the trapezoidal locking block 303. One end of each pull rod 304 slides through the housing 302 and is fixedly connected to the same pull plate 306. The top of the mounting base 4 is fixedly connected with a surrounding plate 9, four right-angle positioning plates 7, and two arc-shaped positioning plates 8. The four right-angle positioning plates 7 can position the rectangular test block mold 6, and the two arc-shaped positioning plates 8 can position the circular test block mold.

[0029] As an example, such as Figure 1 and Figure 3 As shown, two trapezoidal blocks 303 are respectively engaged in the two first slots 5, and the inner walls of the four right-angle positioning plates 7 are connected to the same square test block mold 6.

[0030] As an example, such as Figure 4 As shown, a U-shaped seat 307 is fixedly connected to the top of the pull plate 306. A rotating shaft is rotatably connected to the inner wall of the U-shaped seat 307, and a convex plate 308 is fixedly connected to the surface of the rotating shaft. A rotating handle 309 is fixedly connected to one end of the rotating shaft. An arc-shaped slot 310 is provided at the bottom of the fixed seat 301. The position of the U-shaped seat 307 corresponds to the position of the arc-shaped slot 310. One end of the convex plate 308 matches the arc-shaped slot 310, and one end of the convex plate 308 can be engaged in the arc-shaped slot 310.

[0031] In this embodiment, a test block mold of the required specifications is selected and placed between four right-angle positioning plates 7 or two arc-shaped positioning plates 8. The test block mold is limited and fixed by the four right-angle positioning plates 7. Cement is injected into the square test block mold 6. By starting the vibration motor 10, the vibration motor 10 drives the fixed seat 301 to vibrate. The fixed seat 301 transmits the vibration to the mounting seat 4, vibrating and venting the cement in the test block mold. During the vibration, a small amount of cement overflows onto the surface of the mounting seat 4. After the test block mold has vented, the test block mold is removed. Then, the pull rod 304 drives the two trapezoidal blocks 303 to slide downward along the inner wall of the housing 302, compressing the return spring 305, so that one end of the trapezoidal block 303 disengages from the bottom of the mounting seat 4. The slot 5, and by rotating the rotating handle 309, the rotating handle 309 drives the convex plate 308 to rotate around the rotating shaft, so that one end of the convex plate 308 is engaged in the arc-shaped slot 310 at the bottom of the fixed seat 301, fixing the position of the trapezoidal block 303. Then, by pulling the handle, the handle drives the mounting seat 4 to be pulled out from the inside of the fixed seat 301, so that the cement overflowing from the surface of the mounting seat 4 can be washed or wiped clean. After cleaning, the mounting seat 4 is slidably connected to the inside of the fixed seat 301 and reset. By rotating the rotating handle 309, one end of the convex plate 308 is disengaged from the arc-shaped slot 310. Under the elastic force of the reset spring 305, the trapezoidal block 303 is engaged in the inside of the first slot 5, so that the mounting seat 4 can be reset and fixed.

[0032] As an example, such as Figure 5 As shown, the movable base 1 includes a base shell 101 and a lifting plate 102. Two synchronous electro-hydraulic push rods 103 are fixedly connected to the top of the lifting plate 102. The output ends of the two synchronous electro-hydraulic push rods 103 are fixedly connected to the inner wall of the base shell 101. A caster wheel 104 is fixedly connected to the bottom of the lifting plate 102. A buffer pad is provided at the bottom of the base shell 101 to reduce vibration and noise. A battery pack is provided at the top of the lifting plate 102. An operation panel is provided on one side of the base shell 101. The synchronous electro-hydraulic push rods 103 and the vibration motor 10 are electrically connected to the battery pack and the operation panel.

[0033] As an example, such as Figure 1 and Figure 5 As shown, both ends of the support spring 2 are fixedly connected to the top of the bottom shell 101 and the bottom of the fixing seat 301 through the connecting seat. The bottom of the bottom shell 101 has four through holes corresponding to the positions of the four universal wheels 104.

[0034] As an example, such as Figure 1 and Figure 5As shown, a push handle is fixedly connected to one side of the bottom shell 101, and a handle is fixedly connected to one side of the mounting base 4. The surfaces of the push handle and the handle are provided with anti-slip rubber sleeves to prevent hand slippage during operation.

[0035] In this embodiment, the two synchronous electric hydraulic push rods 103 are activated via the control panel. When the casters 104 are not in contact with the ground, the output ends of the two synchronous electric hydraulic push rods 103 extend to push the lifting plate 102 downward, causing the lifting plate 102 to drive the bottom casters 104 to contact the ground. At this time, the output ends of the two synchronous electric hydraulic push rods 103 lift the bottom shell 101 upward, allowing the casters 104 to extend out of the bottom shell 101. The device can then be moved using the casters 104. During the movement, the direction of movement of the device can be adjusted by the push handle. The device can be pushed to the concrete discharge point using the casters 104. When it is necessary to vibrate the concrete test block, the two synchronous electric hydraulic push rods 103 are activated again, causing the output ends of the two synchronous electric hydraulic push rods 103 to retract, lowering the bottom shell 101 and retracting the casters 104 into the bottom shell 101. As the retraction continues, the bottom of the bottom shell 101 contacts the ground, and the lifting plate 102 drives the casters 104 to retract, thus stopping the device stably.

[0036] Working principle of this utility model:

[0037] S1. Select the corresponding test block mold according to the test requirements, and place the test block mold in the corresponding four right-angle positioning plates 7 or two arc-shaped positioning plates 8. Position the test block mold by the right-angle positioning plates 7 or arc-shaped positioning plates 8.

[0038] S2. The operator activates the two synchronous electric hydraulic push rods 103 in the mobile base 1 via the control panel, causing the output ends of the two synchronous electric hydraulic push rods 103 to extend and push the lifting plate 102 downward, so that the lifting plate 102 drives the bottom caster 104 to contact the ground. At this time, the output ends of the two synchronous electric hydraulic push rods 103 lift the bottom shell 101 upward, so that the caster 104 extends out of the bottom shell 101. The caster 104 pushes the equipment to the designated cement pouring point on the construction site, so that the test block mold corresponds to the cement output end, and cement is injected into the test block mold. After the cement is injected, the synchronous electric hydraulic push rods 103 are activated again, causing the output ends of the two synchronous electric hydraulic push rods 103 to retract, so that the bottom shell 101 descends and the caster 104 retracts into the bottom shell 101. When the retraction continues, the bottom of the bottom shell 101 contacts the ground, and the lifting plate 102 drives the caster 104 to retract, so that the device stops stably.

[0039] S3. Start the vibration motor 10 through the operation panel, so that the vibration motor 10 drives the fixed seat 301 to vibrate. The fixed seat 301 transmits the vibration to the mounting seat 4 to vibrate and vent the cement in the test block mold.

[0040] S4. After the test block is vibrated and the air is vented, turn off the vibration motor 10, remove the test block mold for subsequent curing. If cement overflows from the surface of the mounting base 4, pull down the pull plate 306 to drive the trapezoidal locking block 303 out of the first locking groove 5, rotate the rotating handle 309 to make the convex plate 308 lock in the arc-shaped locking groove 310, pull the handle to pull out the mounting base 4, clean up the overflowing cement, after cleaning, slide the mounting base 4 back into the fixed base 301, and rotate the rotating handle 309 to make one end of the convex plate 308 out of the arc-shaped locking groove 310. Under the elastic force of the return spring 305, the trapezoidal locking block 303 locks in the first locking groove 5, and the mounting base 4 can be fixed.

[0041] The present invention has the following technical effects.

[0042] 1. This utility model uses a structure in which right-angle positioning plates 7 and arc-shaped positioning plates 8 cooperate with mounting base 4. When the vibration motor 10 is working, the four right-angle positioning plates 7 or the two arc-shaped positioning plates 8 limit the square or round test block mold. Without the need for manual fixing of the mold, the square or round test block mold can be positioned, avoiding displacement, collision or tilting of the mold during the operation of the vibration motor 10, thereby preventing a large amount of cement from overflowing and reducing material waste.

[0043] 2. This utility model drives the trapezoidal locking block 303 to disengage from the first locking groove 5 by pulling down the pull plate 306, and rotates the rotating handle 309 to make the convex plate 308 lock into the arc-shaped locking groove 310, thereby pulling the mounting base 4 out from the fixed base 301, realizing the quick disassembly of the mounting base 4, which can facilitate the cleaning of overflowing cement and reduce the difficulty of maintenance.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model 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 or all of the technical features therein.
