Description

Technical Field

[0001] This invention relates to the field of cement water dispensing device technology, and in particular to a cement water dispensing device for engineering testing and detection with quantitative output function. Background Technology

[0002] Cement is a powdery hydraulic inorganic binder; when mixed with water, it forms a paste that hardens in air or water and can firmly bind materials such as sand and stone together. It is generally divided into two types: general-purpose cement, which is the cement commonly used in general civil engineering projects, and special cement, which has special properties or uses, such as G-grade oil well cement, rapid-hardening silicate cement, road silicate cement, aluminate cement, sulfoaluminate cement, etc.

[0003] Before cement products are put into use, their various properties, such as hardness and strength, need to be tested. Only after the products fully meet the actual use requirements can they be put into actual production and use. During the testing process, water needs to be added to the cement sample, and the changes in the index of various cement properties are detected by the change in the amount of water added. Therefore, the control of the amount of water added is particularly important.

[0004] Chinese patent document CN217717758U discloses a cement water-adding device for engineering testing, including a movable base and a water storage tank. A water outlet pipe is fixedly connected to one side of the water storage tank, and a first control valve is installed on the outer surface of the water outlet pipe. A transparent water-adding bucket is fixedly connected to the end of the water outlet pipe away from the water storage tank. Through the coordinated arrangement of the water storage tank, water outlet pipe, first control valve, transparent water-adding bucket, third control valve, and recovery water tank, water addition can be completed simply by controlling the opening and closing of the first, second, and third control valves. The operation is simple, and while accurately ensuring the amount of water added, it eliminates the need for multiple measurements using measuring cylinders, beakers, or quantitative bottles, thus greatly reducing the labor intensity of testing personnel and improving testing efficiency. However, the following drawbacks still exist in the specific implementation process:

[0005] The lack of a mixing structure for the water and cement mixture means that after the water is dispensed in a measured amount, it still needs to be manually poured into the cement container, and the mixture still needs to be manually mixed, which is time-consuming and labor-intensive.

Detailed Implementation

[0033] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0034] Example 1

[0035] like Figure 1-4 As shown, a cement water dispensing device for engineering testing with quantitative output function includes a cart body 1, a water bucket 2 and a handle 8. The handle 8 is located at the left end of the cart body 1, and the water bucket 2 is located at the upper left part of the cart body 1 for holding cement test water.

[0036] Depend on Figure 1 It is known that the four corners of the load-bearing part at the lower end of the cart body 1 are equipped with self-locking universal wheels. By combining the cart body 1 and the handle 8, all the structures for transporting goods can be formed, making it convenient to transport buckets 2 and other items to the required location. Before use, enough clean water should be filled into the inner cavity of the bucket 2 to prevent the water source from being insufficient during the experiment.

[0037] During the experiment, in order to quantitatively inject water into the cavity of the mixing unit 6 through the water injection unit 5, and to stir the mixture of cement and water, please refer to... Figure 1 and Figure 2In this embodiment, a fixed frame 3 is provided on the upper right side of the main body 1 of the cart. An electric cylinder 4 is provided on the upper middle part of the fixed frame 3. A water injection unit 5 for quantitative water addition and a mixing unit 6 for mixing water and cement are provided on the upper right side of the main body 1 of the cart. The mixing unit 6 is located on the right side of the water injection unit 5. An extension mechanism 9 is provided on the upper part of the water injection unit 5. An extension rod 10 for transmitting power is provided on the upper part of the mixing unit 6. A trapezoidal balance plate 7 for balancing torque is provided on the upper part of the extension mechanism 9 and the upper end of the extension rod 10. The lower end of the piston rod at the output end of the electric cylinder 4 extends through the upper middle part of the fixed frame 3 to the lower part and is located on the upper middle part of the trapezoidal balance plate 7.

[0038] As described above, the fixing frame 3 consists of two vertical plates, one horizontal plate, and two L-shaped connecting plates. This design saves space occupied by the fixing frame 3. After the electric cylinder 4 is turned on, the trapezoidal balance plate 7 is moved, which in turn drives the water injection unit 5 to run. At the same time, under the action of the extension rod 10, the mixing unit 6 is driven to run, drawing water out of the inner cavity of the water tank 2 and into the water injection unit 5. Then the electric cylinder 4 runs in reverse, quantitatively sending the water drawn out of the water injection unit 5 into the mixing unit 6. Under the continuous operation of the electric cylinder 4, the mixture of cement and water in the mixing unit 6 can be stirred even when the water injection unit 5 stops running, saving manpower. After stirring, the mixing unit 6 is operated to release the mixed wet cement.

[0039] Specifically, in order to extract and store the water from the inner cavity of bucket 2, see [reference needed]. Figure 3 In this embodiment, the water injection unit 5 includes a housing 51, which is located on the upper right side of the main body 1 of the trolley. A guide rod 52 is provided in the middle of the upper end of the housing 51, extending through the middle of the upper end of the housing 51 and into the inner cavity of the housing 51. A sealing plug 53 is provided at the lower end of the guide rod 52. L-shaped plates 57 are symmetrically arranged on the upper part of the outer surface of the guide rod 52. Triangular support plates 55 are symmetrically arranged on the lower part of the outer surface of the housing 51. A metering mechanism 56 is provided at the upper end of each of the two triangular support plates 55, which cooperates with the L-shaped plate 57 on the same side to control the quantitative movement of the L-shaped plate 57. A one-way valve 54 communicating with the inner cavity of the housing 51 is symmetrically arranged on the lower part of the housing 51.

[0040] The two check valves 54 operate in opposite states. When water is drawn into the inner cavity of the outer casing 51, the left check valve 54 is open and the right check valve 54 is closed. Conversely, when water is released from the inner cavity of the outer casing 51, the left check valve 54 is closed and the right check valve 54 is open, releasing the water from the inner cavity of the outer casing 51.

[0041] As can be seen from the above, first adjust the positions of the two metering mechanisms 56, turn on the electric cylinder 4, pull the extension mechanism 9 upward, and at the same time pull the guide rod 52 and the one-way valve 54 upward. At this time, the water in the inner cavity of the water tank 2 is drawn out through the one-way valve 54 on the left and the water pipe 1 and stored in the inner cavity of the outer shell 51. Then the electric cylinder 4 runs in reverse and releases the water stored in the inner cavity of the outer shell 51 through the one-way valve 54 on the right.

[0042] Specifically, in order to release a measured amount of water stored in the inner cavity of the outer casing 51, see [reference needed]. Figure 3 In this embodiment, the quantitative mechanism 56 includes a concave plate 561 and a fixing mechanism 562. The fixing mechanism 562 is located at the rear of the outer surface of the concave plate 561, and the rear end of the concave plate 561 is provided with a scale.

[0043] Furthermore, the concave plate 561 has symmetrical sliding grooves 5611 at its rear end that communicate with the inner cavity of the concave plate 561, and a number of limiting holes 5612 communicating with the inner cavity of the concave plate 561 are arranged in a rectangular array at the middle of the rear end of the concave plate 561.

[0044] As can be seen from the above, the two sliding grooves 5611 can guide the fixed mechanism 562 when it moves. With the cooperation between the fixed mechanism 562 and the limiting hole 5612 on the same side, and according to the scale on the concave plate 561, the position of the fixed mechanism 562 is precisely adjusted and fixed. Then, under the action of the electric cylinder 4 and the cooperation between the L-shaped plate 57 and the fixed mechanism 562, the water in the inner cavity of the outer shell 51 is quantitatively released.

[0045] Furthermore, in order to precisely adjust the position of the fixing mechanism 562, refer to... Figure 5 In this embodiment, the fixing mechanism 562 includes a sliding frame 5621. The sliding frame 5621 is slidably installed on the rear part of the outer surface of the concave plate 561. The front side of the sliding frame 5621 is symmetrically provided with arc-shaped fixing plates 5622. The upper part of the rear end of the sliding frame 5621 is provided with a limiting rod 5623 that penetrates the upper part of the rear end of the sliding frame 5621 and extends into the inner cavity of the sliding frame 5621. The front part of the upper end of the sliding frame 5621 is provided with a concave plate 5626.

[0046] As can be seen from the above, firstly, the second limiting rod 5623 is pulled out. With the assistance of the scale at the rear end of the concave plate 561, the position of the sliding frame 5621 is precisely adjusted. Then, the second limiting rod 5623 is reinserted into the inner cavity of the first limiting hole 5612 on the same side to fix the position of the sliding frame 5621.

[0047] Specifically, after precisely adjusting the position of the sliding frame 5621, the water inside the outer shell 51 is drained, while preventing the water inside the bucket 2 from re-entering the inner cavity of the outer shell 51. The front middle of the sliding frame 5621 is symmetrically provided with horizontal plates 5625 extending from the front to the rear of the sliding frame 5621. The front ends of the two horizontal plates 5625 are provided with arc-shaped limiting plates 5627. The rear ends of the two horizontal plates 5625 are jointly provided with push plates 5624. The front middle of the concave plate 5626 and the lower rear end of the sliding frame 5621 are jointly provided with spring 5628.

[0048] As can be seen from the above, after the inner cavity of the outer shell 51 is filled with water and the position of the sliding frame 5621 is precisely adjusted, the push plate 5624 is pressed forward. During this process, under the action of the two springs 5632, the concave plate 5626 and the wedge block 5633 are pushed upward simultaneously, so that the two wedge blocks 5633 enter the inner cavity of the limiting groove 5634 on the same side, fixing the position of the horizontal plate 5625 and the arc-shaped limiting plate 5627.

[0049] Furthermore, the lower end of the vertical portion of the L-shaped plate 57 is provided with symmetrical slide rails 572, and the outer surfaces of the two slide rails 572 are provided with a limiting rod 575. The front part of the lower end of the vertical portion of the L-shaped plate 57 is provided with a vertical plate 573, and the lower rear end of the vertical plate 573 is provided with a spring 574 between the lower rear end of the vertical plate 573 and the outer surface of the limiting rod 575. The lower rear end of the vertical portion of the L-shaped plate 57 is provided with a metal elastic plate 571 that cooperates with the concave plate 5626 on the same side.

[0050] Furthermore, the sliding frame 5621 has symmetrical guide grooves 5631 on the left and right sides of the front side, which communicate with the upper end of the sliding frame 5621. Springs 5632 are provided in the middle of the bottom wall of the inner cavity of the two guide grooves 5631.

[0051] Furthermore, the upper front of both horizontal plates 5625 is provided with a limiting groove 5634 that communicates with the lower end, and the lower part of the inner surface of the concave plate 5626 is provided with a wedge block 5633 between the left and right side walls.

[0052] When the electric cylinder 4 reverses, it presses the sealing plug 53 downwards. During this process, the two L-shaped plates 57 move downwards synchronously. When the limiting rod 575 enters the inner cavity of the two arc-shaped limiting plates 5627 on the same side, the metal elastic plate 571 presses the concave plate 5626, separating the wedge block 5633 from the inner cavity of the limiting groove 5634 on the same side. Then, under the action of the spring 5628 and the push plate 5624, the horizontal plate 5625 and the arc-shaped limiting plate 5627 are dragged synchronously. Move backward and drag the limiting rod 575 backward into the inner cavity of the two arc-shaped fixing plates 5622. The limiting rod 575 is fixed by the two arc-shaped fixing plates 5622 and the two arc-shaped limiting plates 5627. When the electric cylinder 4 runs forward again, the sealing plug 53 and the limiting rod 575 remain stable and do not move. This ensures that the water in the inner cavity of the water bucket 2 will not re-enter the inner cavity of the outer shell 51, thereby achieving the purpose of quantitatively injecting water into the inner cavity of the outer shell 61.

[0053] Example 2

[0054] This embodiment adds a mixing unit 6 to the second embodiment, which can stir the mixture of cement and water while adding water to the cement. This can reduce the fatigue of manual labor and improve the mixing efficiency.

[0055] Specifically, after water is injected into the inner cavity of outer shell 51, into the inner cavity of outer shell 61, in order to mix the cement and water mixture without affecting the water injection unit 5, refer to... Figure 7 In this embodiment, the extension mechanism 9 includes a second outer shell 91. A guide rod 92 is provided at the middle of the upper end of the second outer shell 91, extending through the upper end of the second outer shell 91 and into the inner cavity of the second outer shell 91. A sealing plug 94 is provided at the lower end of the guide rod 92, and a spring 95 is provided at the lower end of the sealing plug 94.

[0056] As can be seen from the above, after the electric cylinder 4 drives the guide rod 2 92 to move downward, it can simultaneously drive the guide rod 1 52 and the sealing plug 1 53 to move downward synchronously, so that the water in the inner cavity of the outer shell 1 51 is released quantitatively under the action of the fixing mechanism 562. Then, the position of the guide rod 1 52 is fixed by the fixing mechanism 562. During the repeated forward and reverse operation of the electric cylinder 4, under the action of the spring 4 95, rigid damage to the fixing mechanism 562 caused by the L-shaped plate 57 can be prevented. At the same time, it can also ensure that the electric cylinder 4 can operate normally in both forward and reverse directions, thereby driving the mixing unit 6 to operate continuously.

[0057] Specifically, in order to simultaneously stir the dry cement inside the outer casing 361 while the electric cylinder 4 is running, see [reference needed]. Figure 8In this embodiment, the mixing unit 6 includes a housing 61. The middle of the top wall and the middle of the bottom wall of the inner cavity of the housing 61 are provided with a stirring mechanism 64. The upper right side of the housing 61 is provided with a feeding trough 63 for filling dry cement into the inner cavity of the housing 61. The lower right side of the outer surface of the housing 61 is provided with a discharge trough 62 that is common to the inner cavity of the housing 61.

[0058] As described above, before using the device, the required weight of dry cement is filled into the inner cavity of the outer shell 61 through the feed trough 63. Then, water is injected into the inner cavity of the outer shell 61 by the operation of the electric cylinder 4. At the same time as the injection, the stirring mechanism 64 starts to run under the action of the electric cylinder 4, the extension mechanism 9, and the extension rod 10, etc., to stir the dry cement and accelerate the mixing speed of cement and water. Then, the water injection into the inner cavity of the outer shell 61 is stopped under the action of the fixing mechanism 562, etc. At this time, the electric cylinder 4 continues to run, and under the action of the stirring mechanism 64, the mixture of cement and water is continuously stirred until the two are completely mixed.

[0059] Furthermore, in order to achieve the purpose of mixing cement via the mixing mechanism 64 as described above, see [reference needed]. Figure 8 and Figure 9 In this embodiment, the mixing mechanism 64 includes two rotating rings 641. Four guide rods 642 are arranged in a ring array on the outer side between the opposite surfaces of the two rotating rings 641. A follower plate 644 is arranged on the upper part of the outer surface of the four guide rods 642. A mixing plate 643 for mixing cement is arranged on the side of the outer surface of the four guide rods 642 away from the follower plate 644. A double spiral plate 645 for driving the mixing plate 643 to rotate is arranged in the middle of the upper end of the outer shell 61. The lower end of the double spiral plate 645 extends through the middle of the upper end of the outer shell 61, the middle of the upper end of the rotating ring 641 located at the upper part, and the middle of the upper end of the follower plate 644 to the lower part.

[0060] The upper middle part of the follower plate 644 is provided with a connecting groove that matches the motion trajectory of the double helix plate 645;

[0061] As can be seen from the above, the double helix plate 645 has a helical structure. When the double helix plate 645 moves up and down, the guide rod 642 is driven to rotate under the mutual cooperation between the double helix plate 645 and the follower plate 644, which in turn drives several mixing plates 643 to rotate, so as to achieve the purpose of mixing the cement and water mixture.

[0062] It should be noted that the specific installation method, circuit connection method, and control method of the electric cylinder 4, one-way valve 54, and metal elastic plate 571 used in the above embodiment are all conventional designs, and will not be described in detail in this invention.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
