Description

Technical Field

[0001] This application relates to the field of cement mortar flowability testing technology, and more specifically, to a cement mortar flowability testing instrument. Background Technology

[0002] A cement mortar flowability tester is a specialized device used to test the flowability of mortar in materials such as pozzolanic silicate cement and composite silicate cement. This instrument evaluates the flowability of cement by vibrating the mortar and measuring its diffusion diameter, providing a basis for determining the standard consistency water requirement. For example, Chinese patent CN202422185065.X discloses a cement mortar flowability tester, whose technical solution includes: a base placed on a table; a sliding rod vertically slidably connected to the base; a circular platform horizontally positioned above the sliding rod; a cone placed at the center of the circular platform; a drive mechanism for controlling the vertical reciprocating motion of the sliding rod; and support rods arranged around the circular platform, with a measuring scale horizontally slidably connected to each support rod, the measuring scale being in contact with the surface of the circular platform. This utility model has the following advantages and effects: by setting a measuring ruler that is independently slidably connected in four directions, the position of the measuring ruler can be quickly adjusted after the cement mortar flows, so that the measuring ruler is in time at the edge of the cement mortar, and then the reading and recording are carried out uniformly. The operation process is simple, and even if the cement mortar continues to spread, it will not affect the detection accuracy.

[0003] However, this existing technology has certain limitations in use. After the measurement is completed, if the cement mortar continues to spread and comes into contact with the measuring ruler that remains in place, it may cause material to adhere, affecting the cleanliness of the ruler and the accuracy of subsequent measurements. In addition, the measuring ruler must be completely moved out of the movable table area before the movable table can be removed from the fixed table, so the ease of use needs to be improved. Summary of the Invention

[0004] The purpose of this application is to provide a cement mortar flowability tester, which can solve the technical problems of existing cement mortar flowability testers. After the measurement is completed, if the cement mortar continues to spread and comes into contact with the measuring ruler that remains in place, it may cause material adhesion, affecting the cleanliness of the ruler and the accuracy of subsequent measurements. In addition, the measuring ruler must be completely moved out of the range of the movable table before the movable table can be removed from the fixed table, which makes it difficult to use.

[0005] This application provides a cement mortar flowability tester, including a frame, a fixed disc and a movable disc. The fixed disc is movably disposed above the frame. A drive assembly is disposed on the frame to drive the fixed disc to move up and down. The movable disc is detachably disposed on the top of the fixed disc. Four measuring components are evenly disposed on the periphery of the fixed disc.

[0006] The measuring assembly includes a rotating plate and a measuring ruler. The rotating plate is hinged to the fixed disk, and the measuring ruler is slidably mounted on the rotating plate and can be attached to the top of the movable disk.

[0007] Preferably, the rotating plate is provided with a locking assembly, which includes a mounting block, a locking rod, a first handle, and an elastic element. The mounting block is fixedly mounted on the rotating plate. The measuring ruler and the locking rod both slide through the mounting block. One end of the locking rod can abut against the measuring ruler. The first handle is fixedly connected to the other end of the locking rod. The elastic element is pre-pressed between the mounting block and the first handle.

[0008] Preferably, the rotating plate is provided with a counterweight assembly, which includes a connecting rod and a counterweight block. The end of the rotating plate away from the fixed disc has a mounting hole, the connecting rod passes through the mounting hole, and the counterweight block is fixedly connected to the connecting rod.

[0009] Preferably, the measuring ruler is provided with scale lines, and a second handle is fixedly provided at the end of the measuring ruler away from the movable disc.

[0010] Preferably, two connecting components are symmetrically arranged on the fixed disk. Each connecting component includes a connecting screw and a third handle. The connecting screw is threaded through the fixed disk, and the third handle is fixedly disposed at the end of the connecting screw away from the fixed disk. A connecting hole is provided on the movable disk, and the connecting screw can be inserted into the connecting hole and engaged with the connecting hole for limiting.

[0011] Preferably, a top rod is fixedly provided at the lower end of the movable disc, and a through hole is provided on the fixed disc, through which the top rod can pass.

[0012] Preferably, the frame includes a base, a support rod, and a sleeve. The support rod is fixedly mounted on the base, and the sleeve is fixedly mounted on the top of the support rod. The drive assembly includes a motor, a cam, a push rod, and a roller. The motor is fixedly mounted on the support rod, and the output shaft of the motor is connected to the cam. The push rod is slidably mounted inside the sleeve, and the top of the push rod is fixedly connected to the fixed disc. The roller is rotatably mounted on the bottom of the push rod, and the roller slides against the cam.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a cement mortar flowability tester. During use, a drive assembly moves a fixed disc up and down above the frame, causing the cement mortar on the movable disc to vibrate and begin to spread. During measurement, the measuring scale is slid towards the center of the movable disc, aligning its end with the edge of the spread cement mortar for reading and recording. The rotating plate is then flipped, completely lifting the measuring scale off the surface of the movable disc. After measurement, the entire movable disc can be removed for cleaning. This tester allows the measuring scale to be flipped and lifted immediately after measurement, detaching it from the cement mortar surface and preventing sticking caused by continued cement mortar spread. This ensures the cleanliness of the measuring scale and the accuracy of subsequent measurements. Furthermore, when disassembling the movable disc, there is no need to slide the measuring scale a long distance; simply flipping it creates space, making operation more convenient and faster.

Furthermore, the machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art. These are prior art known to those skilled in the art and will not be described in detail here.

[0037] like Figures 1 to 5 As shown, this application embodiment provides a cement mortar flowability tester, including a frame 1, a fixed disc 2 and a movable disc 3. The fixed disc 2 is movably disposed above the frame 1. A drive assembly 4 is disposed on the frame 1. The drive assembly 4 is used to drive the fixed disc 2 to jump up and down. The movable disc 3 is detachably disposed on the top of the fixed disc 2. Four measuring components 5 are evenly disposed on the periphery of the fixed disc 2.

[0038] The measuring component 5 includes a rotating plate 51 and a measuring ruler 52. The rotating plate 51 is hinged on the fixed disk 2, and the measuring ruler 52 is slidably mounted on the rotating plate 51. The measuring ruler 52 can be attached to the top of the movable disk 3.

[0039] During use, the drive assembly 4 drives the fixed disc 2 to bounce up and down above the frame 1, causing the cement mortar on the movable disc 3 to be vibrated and begin to spread. During measurement, the measuring ruler 52 is slid towards the center of the movable disc 3, so that the end of the measuring ruler 52 is aligned with the edge of the spread cement mortar for reading and recording. Then, the rotating plate 51 is flipped over, thereby completely lifting the measuring ruler 52 off the surface of the movable disc 3. After the measurement is completed, the entire movable disc 3 can be removed for cleaning.

[0040] After the measurement is completed, the measuring instrument can immediately flip and lift the measuring ruler 52 to remove it from the cement mortar surface, avoiding the problem of the ruler sticking due to the continued spread of cement mortar. This ensures the cleanliness of the measuring ruler 52 and the accuracy of subsequent measurements. Moreover, when disassembling the movable disc 3, there is no need to slide the measuring ruler 52 a long distance out; simply flipping it over makes room, making the operation more convenient and faster.

[0041] like Figures 1 to 4 As shown, in this embodiment, a locking component 6 is provided on the rotating plate 51. The locking component 6 includes a mounting block 61, a locking rod 62, a first handle 63, and an elastic element 64. The mounting block 61 is fixedly mounted on the rotating plate 51. The measuring ruler 52 and the locking rod 62 both slide through the mounting block 61. One end of the locking rod 62 can abut against the measuring ruler 52. The first handle 63 is fixedly connected to the other end of the locking rod 62. The elastic element 64 is pre-pressed between the mounting block 61 and the first handle 63.

[0042] During measurement, the operator holds the first handle 63 and pulls the locking lever 62 outward. At this time, the elastic element 64 is stretched, which releases the lock on the measuring scale 52. The measuring scale 52 is slid towards the center of the movable disk 3, so that the end of the measuring scale 52 is aligned with the edge of the diffused cement mortar for reading and recording. Then, the first handle 63 is released. Under the elastic force of the elastic element 64, the locking lever 62 is pushed towards the measuring scale 52, and the measuring scale 52 is locked in the mounting block 61 by friction. Then, the rotating plate 51 is flipped. The elastic element 64 is a spring. The locking assembly 6 can prevent the measuring scale 52 from sliding and falling after flipping. Moreover, the locking and unlocking of the measuring scale 52 can be achieved by simply pulling the first handle 63, which is convenient, quick and easy and improves the measurement efficiency.

[0043] To further prevent cement mortar from sticking to the measuring ruler, the operator can immediately lock the measuring ruler 52 and flip the rotating plate 51 after aligning the end of the measuring ruler 52 with the edge of the diffused cement mortar. After all four measuring rulers 52 have been measured, the readings and records can be taken at the same time. Under the locking of the locking component 6, the relative position of the measuring ruler 52 and the rotating plate 51 remains unchanged after flipping, and the operator can read the correct measurement value.

[0044] like Figures 1 to 4 As shown, in this embodiment, a counterweight assembly 7 is provided on the rotating plate 51. The counterweight assembly 7 includes a connecting rod 71 and a counterweight block 72. An installation hole 53 is provided at one end of the rotating plate 51 away from the fixed disc 2. The connecting rod 71 passes through the installation hole 53, and the counterweight block 72 is fixedly connected to the connecting rod 71.

[0045] By utilizing the gravity of the counterweight 72, the rotating plate 51 remains vertically downward when not disturbed by external forces. At this time, the measuring ruler 52 is kept away from the movable disc 3 to prevent interference with the diffusion of cement mortar. Moreover, the rotating plate 51 can quickly return to its initial position after the external force is removed, preventing interference with the disassembly of the movable disc 3.

[0046] like Figures 1 to 4 As shown, in this embodiment, the measuring ruler 52 is provided with scale lines, and a second handle 54 is fixedly provided at the end of the measuring ruler 52 away from the movable disk 3; the scale lines enable the operator to read the measurement value quickly and accurately without the need for additional measuring tools, thus improving measurement efficiency; the second handle 54 facilitates the operator to apply force to move the measuring ruler 52, thus improving ease of use.

[0047] like Figures 1 to 5 As shown in this embodiment, two connecting components 8 are symmetrically arranged on the fixed disk 2. The connecting component 8 includes a connecting screw 81 and a third handle 82. The connecting screw 81 is threaded through the fixed disk 2. The third handle 82 is fixedly arranged at the end of the connecting screw 81 away from the fixed disk 2. A connecting hole 31 is provided on the movable disk 3. The connecting screw 81 can be inserted into the connecting hole 31 and is limited to cooperate with the connecting hole 31.

[0048] When installing the movable disc 3, place it inside the fixed disc 2, then grasp the third handle 82 and rotate the connecting screw 81 on the fixed disc 2. This inserts the connecting screw 81 into the connecting hole 31 on the movable disc 3, creating a limiting fit between the connecting screw 81 and the connecting hole 31, thus firmly pressing the movable disc 3 onto the fixed disc 2. When removing the movable disc 3, rotate the third handle 82 in the opposite direction to disengage the connecting screw 81 from the connecting hole 31, allowing the movable disc 3 to be removed. The connecting assembly 8 ensures a secure connection between the movable disc 3 and the fixed disc 2, preventing the movable disc 3 from loosening or shifting during the up-and-down movement of the fixed disc 2, thus guaranteeing measurement accuracy. Moreover, the operator can easily install and remove the movable disc 3 simply by rotating the third handle 82, making the operation simple and quick, and improving the efficiency of the equipment.

[0049] like Figure 1 and 2 As shown, in this embodiment, a push rod 32 is fixedly provided at the lower end of the movable disc 3, and a through hole 21 is provided on the fixed disc 2, through which the push rod 32 can pass. When installing the movable disc 3, the push rod 32 is inserted into the through hole 21 to quickly position and align the installation position of the movable disc 3. When disassembling the movable disc 3, the push rod 32 provides a force point for the operator to push the movable disc 3 out from below with their fingers or tools, improving the ease of use.

[0050] like Figure 1 As shown, in this embodiment, the frame 1 includes a base 11, a support rod 12, and a sleeve 13. The support rod 12 is fixedly mounted on the base 11, and the sleeve 13 is fixedly mounted on the top of the support rod 12. The drive assembly 4 includes a motor 41, a cam 42, a push rod 43, and a roller 44. The motor 41 is fixedly mounted on the support rod 12, and the output shaft of the motor 41 is connected to the cam 42. The push rod 43 is slidably mounted inside the sleeve 13, and the top of the push rod 43 is fixedly connected to the fixed disc 2. The roller 44 is rotatably mounted on the bottom of the push rod 43, and the roller 44 slides against the cam 42.

[0051] When in use, the motor 41 is turned on to drive the cam 42 to rotate. The outer contour of the cam 42 pushes the roller 44 that slides against it, thereby driving the push rod 43 to make precise up-and-down reciprocating motion inside the sleeve 13. Finally, the jump is transmitted to the fixed disc 2, causing the fixed disc 2 to jump up and down above the frame 1.

[0052] Working principle: When the cement mortar flowability tester provided in this application is in use, the motor 41 drives the cam 42 to rotate. The outer contour of the cam 42 pushes the roller 44 that slides against it, thereby driving the push rod 43 to make precise up-and-down reciprocating motion within the sleeve 13. Finally, the vibration is transmitted to the fixed disc 2, causing the fixed disc 2 to bounce up and down above the frame 1. This causes the cement mortar on the movable disc 3 to be vibrated and begin to spread. During measurement, the operator holds the first handle 63 and pulls out the locking rod 62. At this time, the elastic element 6 4. When stretched, the locking of the measuring ruler 52 can be released. Slide the measuring ruler 52 towards the center of the movable disk 3, align the end of the measuring ruler 52 with the edge of the diffused cement mortar, and take a reading and record it. Then release the first handle 63. Under the elastic force of the elastic element 64, the locking rod 62 is pushed towards the measuring ruler 52 and locked in the mounting block 61 by friction. Then flip the rotating plate 51 to completely lift the measuring ruler 52 off the surface of the movable disk 3. After the measurement is completed, the entire movable disk 3 can be removed for cleaning.

[0053] When installing the movable disc 3, place the movable disc 3 into the fixed disc 2, then hold the third handle 82 and rotate the connecting screw 81 on the fixed disc 2 so that the connecting screw 81 is inserted into the connecting hole 31 on the movable disc 3, so that the connecting screw 81 and the connecting hole 31 form a limiting fit, thereby firmly pressing the movable disc 3 onto the fixed disc 2; when removing the movable disc 3, rotate the third handle 82 in the opposite direction so that the connecting screw 81 is disengaged from the connecting hole 31, and the movable disc 3 can be removed.

[0054] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
