Description

Technical Field

[0001] The invention relates to the technical field of concrete detection, in particular to a concrete Vebe consistency meter. Background Art

[0002] The concrete Vibe consistency meter uses vibration to make the concrete mixture reach a flat state and measures the time required to evaluate the viscosity of the concrete. It is an important measuring instrument in the construction industry in controlling the quality of concrete mixtures.

[0003] When using the Vebe consistency meter, the vibration device needs to be turned on. When the bottom surface of the transparent disc is covered with concrete slurry, the operator stops the vibration of the device. At this time, the value displayed on the controller is the Vebe consistency value.

[0004] However, the concrete slurry being tested actually contains a certain amount of moisture, and in order for the transparent disc to smoothly enter the concrete container, the diameter of the transparent disc is smaller than that of the concrete container, so there will be a certain gap between the two.

[0005] When the transparent disc comes into contact with the concrete slurry, some liquid slurry will overflow through the gap to the upper surface of the transparent disc. The overflowing slurry blocks the workers' line of sight, making it impossible for the workers to accurately judge whether the bottom surface of the transparent disc is fully covered by the concrete slurry, which greatly affects the detection accuracy.

DETAILED DESCRIPTION

[0040] Although the present invention may be described with respect to a particular application or industry, those skilled in the art will recognize the broader applicability of the present invention. Those of ordinary skill in the art will recognize that terms such as above, below, upward, downward, etc. are used to describe the drawings and do not represent limitations on the scope of the present invention as defined by the appended claims. Any numerical designations such as first or second are merely exemplary and are not intended to limit the scope of the present invention in any way.

[0041] Example 1

[0042] A concrete Vibe consistency tester, such as Figure 1-18As shown, it includes a vibration table 1, a bearing platform 2, a holding pot 3, a metering barrel 4, a sliding rod 5, a first rotating frame 6, an annular portion 61, a hopper 7, a second rotating frame 8, a fixing rod 9, a hollow fixing box 93, a glass pressing plate 10, a fixing seat and a handle; the vibration table 1 is fixedly connected to the bearing platform 2; the bearing platform 2 is connected to the holding pot 3; the metering barrel 4 is placed in the holding pot 3; the metering barrel 4 is connected to two handles through the fixing seat; the rear part of the vibration table 1 is fixedly connected to the sliding rod 5; the sliding rod 5 is bolted to the first rotating frame 6, and the first rotating frame 6 is provided with an annular portion 61; the hopper 7 is placed on the annular portion 61, and the hopper 7 is in contact with the metering barrel 4; the sliding rod 5 is bolted to the second rotating frame 8; the second rotating frame 8 is bolted to the fixing rod 9; the fixing rod 9 is threadedly connected to the hollow fixing box 93, and the hollow fixing box 93 is fixedly connected to the glass pressing plate 10;

[0043] It also includes a rod cavity 91, an air inlet nozzle 92, a mounting groove ring 101, an adsorbent 102 and a connecting pipe 103; the fixed rod 9 is provided with a rod cavity 91; the upper part of the fixed rod 9 is provided with an air inlet nozzle 92; the outer ring surface of the glass pressure plate 10 is fixedly connected with a mounting groove ring 101, and the mounting groove ring 101 is hollow with an opening at the bottom; the adsorbent 102 is inserted into the mounting groove ring 101; the hollow fixed box 93 is connected with the mounting groove ring 101 through the connecting pipe 103, and the connecting pipe 103 is in contact with the adsorbent 102.

[0044] The hopper 7 is made of metal; the contact surface between the annular portion 61 and the hopper 7 is magnetically arranged, and the magnetic arrangement of the annular portion 61 makes it less likely for the metal hopper 7 to shake or deviate during operation.

[0045] Before the device is put into operation, the air inlet nozzle 92 is first connected to the external air pump, and the external air pump is connected to the vibration table 1 for communication. Then, the staff loosens the fixing bolts of the second rotating frame 8 and the slide bar 5, and then turns the second rotating frame 8 to rotate. The second rotating frame 8 drives the observation piece composed of the fixing rod 9, the hollow fixing box 93 and the glass pressure plate 10 to rotate until the second rotating frame 8 and the observation piece do not affect the subsequent operation of the hopper 7, and then tightens the fixing bolts of the second rotating frame 8 and the slide bar 5;

[0046] Then the staff pours the stirred measuring material in batches (at least three times) from the upper opening of the hopper 7, and another staff holds the two handles with both hands to make the metering bucket 4 more stable, so that the measuring material will not flow out from the lower opening of the metering bucket 4. The measuring material enters the metering bucket 4 through the drainage of the hopper 7, and the measuring material is supported by the containing pot 3. After each time the measuring material is poured into the metering bucket 4, the staff also needs to use a stirring rod to tamp the measuring material, so that the measuring material will not produce hollows in the metering bucket 4, avoiding the subsequent hollows affecting the measurement data;

[0047] After the measuring material fills the measuring barrel 4 and the staff has finished inserting and tamping the measuring material, the staff loosens the fixing bolts of the slide bar 5 and the first rotating frame 6, adjusts the first rotating frame 6 and the hopper 7 to a position that does not affect the subsequent operation of the glass pressing plate 10, and then the staff takes away the measuring barrel 4 by the handle. At this time, the measuring material is also formed as shown in the figure. Fig.18 Example dirt pile shown;

[0048] Then the staff loosens the fixing bolts of the second rotating frame 8 and the slide rod 5, resets the second rotating frame 8 and the observation piece, loosens the fixing bolts of the second rotating frame 8 and the fixing rod 9, adjusts the observation piece to the preset position (i.e. the bottom surface of the glass pressure plate 10 is in contact with the top surface of the sample soil pile), and at this time the staff holds the observation piece, then starts the vibration table 1, and at the same time the staff loosens the observation piece, and the observation piece contacts the sample soil pile;

[0049] Under the operation of the vibration table 1, the support table 2 starts to vibrate, and the staff starts counting through the external counting device. The support table 2 drives the connected holding pot 3 to vibrate, and the holding pot 3 drives the supported sample soil pile to collapse, forming a collapsed soil pile. At this time, the observation piece also moves downward. When the bottom surface of the glass platen 10 is completely covered by the collapsed soil pile, the staff stops counting, and then reads the information on the external counting device, and a detection work is completed;

[0050] However, in the prior art, when the glass platen 10 contacts the collapsed soil pile, part of the liquid slurry will overflow to the upper surface of the glass platen 10 through the gap between the containing pot 3 and the glass platen 10, which will affect the detection accuracy.

[0051] Therefore, the glass platen 10 is provided with a mounting groove ring 101 and an adsorbent 102. When the vibration table 1 is started, the external air pump starts to work to generate adsorption force, which is sequentially transmitted to the adsorbent 102 through the rod cavity 91, the hollow fixing box 93 and the connecting pipe 103.

[0052] Afterwards, when the slurry overflows through the gap and is about to reach the upper surface of the glass platen 10, the slurry will first contact the adsorption member 102, and the adsorption member 102 will absorb the slurry and also filter and separate the slurry, so that the slurry is divided into liquid water and slurry residue. At this time, the adsorption force of the connecting pipe 103 will suck out the liquid water, and then discharge it from the external air pump, while the slurry residue will not be sucked out because it is blocked by the adsorption member 102. In this way, the slurry will no longer overflow to the upper surface of the glass platen 10, thus solving the problem of the prior art that when the glass platen 10 contacts the collapsed soil pile, part of the liquid slurry will overflow to the upper surface of the glass platen 10 through the gap between the containing pot 3 and the glass platen 10.

[0053] The adsorbent 102 blocks the pulp residue, so that the pulp residue will not block the rod cavity 91, the hollow fixing box 93 and the connecting pipe 103, making the device very convenient to maintain during use. After the device is finished working, it is only necessary to connect the air inlet of the external air pump to the water source, and then control the external air pump to work in reverse to flush the rod cavity 91, the hollow fixing box 93 and the connecting pipe 103.

[0054] The adsorption member 102 and the mounting groove ring 101 are plug-in connected. After each operation of the device is completed, the adsorption member 102 is pulled out, and the adsorption member 102 is rinsed or replaced, and then the processed adsorption member 102 is inserted back into the mounting groove ring 101 to complete the maintenance of the adsorption member 102.

[0055] Example 2

[0056] On the basis of Example 1, Figure 1-Figure 10 As shown,

[0057] The bearing platform 2 includes a hollow base 21, a fixed plate 22 and a support member 23; the vibration platform 1 is fixedly connected to the hollow base 21; the support member 23 is fixedly connected inside the hollow base 21; the support member 23 is fixedly connected to the fixed plate 22, and the fixed plate 22 is connected to the holding pot 3 through a fixing bolt;

[0058] The hollow bottom platform 21 is fixedly connected with the slide rail 201; the slide rail 201 is connected with four slide blocks 202; each slide block 202 is fixedly connected with a convergence wheel 203, and each convergence wheel 203 is provided with a torsion spring; each convergence wheel 203 is wound with a fixed rope 205; each fixed rope 205 ... Each of the sliders 202 is fixedly connected with a fixing hook 206; and the hollow base 21 is rotatably connected with four limiting pieces 2051, and each fixing rope 205 passes through the limiting piece 2051 at the corresponding position, and the fixing hook 206 is located above the limiting piece 2051; each slider 202 is fixedly connected with a clamping block 204, and the clamping block 204 has a clamping groove; the vibration table 1 is connected with a limiting assembly, and the limiting assembly passes through the bottom of the hollow base 21, and the limiting assembly is connected to the support 23.

[0059] The limiting assembly includes an electric telescopic rod 211, a pushing column 212, a telescopic member 213 and a limiting block 214; the support member 23 is a hollow setting with an opening at the bottom; the vibration table 1 is fixedly connected to the electric telescopic rod 211; the electric telescopic rod 211 is fixedly connected to the pushing column 212; the pushing column 212 is plugged into the support member 23; the support member 23 is connected to four telescopic members 213; each telescopic member 213 is fixedly connected to a limiting block 214, and each limiting block 214 is located on one side of the card block 204 at the corresponding position.

[0060] Since the prior art requires another worker to hold the two handles with both hands when pouring the measured material into the metering bucket 4 to make the metering bucket 4 more stable, this results in the need for the cooperation of at least two workers when the device is used, which greatly limits the convenience of the device.

[0061] Therefore, the device is also provided with a fixing rope 205 and a fixing hook 206. Before pouring the measured material into the metering bucket 4, the staff pinches the fixing hooks 206 on the left and right, and then pulls the two fixing hooks 206. When the fixing hooks 206 are pulled, the corresponding fixing rope 205 is pulled out. When the fixing rope 205 is pulled out, the corresponding tightening wheel 203 is driven to rotate, and the torsion spring of the tightening wheel 203 is generated, and the restoring elastic force of the subsequent rewinding fixing rope 205 is generated.

[0062] After that, the two fixing hooks 206 are respectively buckled with the handles at the corresponding positions, and then the electric telescopic rod 211 starts to work and unfold, driving the connected push column 212 to move upward. When the push column 212 moves, it squeezes the air inside the support member 23 to form high-pressure air. The high-pressure air enters the telescopic member 213 connected to the support member 23, and the telescopic part of the telescopic member 213 unfolds, driving the connected limit block 214 to move toward the direction of the card block 204 at the corresponding position, until the limit block 214 is embedded in the card slot of the card block 204, and the fixing rope 214 at the corresponding position is locked. 205 is clamped by the limit block 214 and the clamping block 204 at the corresponding position, so that the limiting work of the left and right fixing ropes 205 is realized, so that the left and right fixing ropes 205 can limit the two handles on the measuring bucket 4 through their respective fixed fixing hooks 206, and then the measuring bucket 4 is limited and fixed, so that there is no need for another staff member to cooperate in the work, thus avoiding the problem that the existing technology requires the cooperation of at least two staff members when in use, which greatly limits the convenience of the device.

[0063] Example 3

[0064] On the basis of Example 2, Figure 11-Figure 16 As shown,

[0065] The support member 23 includes a hollow cylinder 231, a rotating ring 232, a top cover 233, and a connecting strip 234; the hollow base 21 is fixedly connected to the hollow cylinder 231, and the hollow cylinder 231 passes through the bottom of the hollow base 21, and the hollow cylinder 231 is plugged into the pushing column 212; the hollow cylinder 231 is rotatably connected to the rotating ring 232, and the rotating ring 232 is connected to the four telescopic members 213; the rotating ring 232 is rotatably connected to the top cover 233; the top cover 233 is fixedly connected to the hollow cylinder 231 through the connecting strip 234.

[0066] It also includes a collecting assembly; the upper part of the metering barrel 4 is covered with a collecting assembly;

[0067] The collecting assembly includes a collecting ring and an elastic fixing plate; the collecting ring is fixedly connected with the elastic fixing plate; and the elastic fixing plate is sleeved with the metering barrel 4.

[0068] It also includes a stirring assembly and a rotation limiting assembly; the metering barrel 4 is fixedly connected to four fixing seats, and two fixing seats adjacent to each other in front and back are rotatably connected to a handle, and each fixing seat is provided with a torsion spring, and the torsion force of the fixing seat torsion spring is less than the torsion spring of the gathering wheel 203; each handle is connected to a stirring assembly, and each stirring assembly is connected to the metering barrel 4; the collecting assembly is provided with two rotation limiting assemblies. The stirring assembly on the right side of the metering barrel 4 includes a first inclined strip, an elastic fixing member, a second inclined strip, an insert, a clamping strip and a flexible wrapping strip; the handle is provided with a cross bar; the handle cross bar is fixedly connected to the first inclined strip; the metering barrel 4 is fixedly connected to the elastic fixing member; the elastic fixing member is fixedly connected to the second inclined strip; the second inclined strip is fixedly connected to a number of inserts; the metering barrel 4 is fixedly connected to the flexible wrapping strip, and the flexible wrapping strip passes through the metering barrel 4; each insert passes through the flexible wrapping strip; the handle cross bar is fixedly connected to the clamping strip.

[0069] It also includes an air cavity; the elastic fixing plate is provided with an air cavity;

[0070] Among them, the rotation limiting component on the right part of the collecting component includes a flexible tube, an airbag and an opening spring piece; the elastic fixing piece is connected to the flexible tube, and the flexible tube passes through the collecting ring piece; the flexible tube is connected to the airbag; the airbag is fixedly connected to the opening spring piece.

[0071] In the prior art, in order to ensure that the measured material can fill the metering barrel 4 with a sufficient amount when pouring the measured material from the hopper 7 into the metering barrel 4, an excess amount of the measured material is deliberately poured into the hopper 7 when the metering barrel 4 is about to be filled with the measured material, and then the measured material in the metering barrel 4 is tamped so that the metering barrel 4 can be filled with a sufficient amount of the measured material. However, at this time, a portion of excess material will exist in the hopper 7.

[0072] In order to prevent the excess material from falling into the holding pot 3 when the hopper 7 is removed, the prior art requires the staff to hold a cardboard with a hollowed-out middle portion and put it on the top of the metering barrel 4, so that when the hopper 7 is removed, the excess material will fall on the cardboard instead of falling into the holding pot 3. However, this method requires at least two staff members to cooperate in operating the device, which is very inconvenient. In addition, since the cardboard is flat and is held by the staff, the excess material falling on the cardboard will still roll into the holding pot 3 under the shaking of the staff's hand, which will still affect the final measurement data.

[0073] Therefore, the device is also provided with a collecting ring sheet and an elastic fixing sheet, and the collecting ring sheet is sleeved with the metering barrel 4 through the elastic fixing sheet, and the fixing of the collecting ring sheet is achieved through the interference fit between the elastic fixing sheet and the metering barrel 4, and the collecting ring sheet is arranged obliquely, so that the excess material will move in the direction of the elastic fixing sheet under the guidance of the collecting ring sheet, and will eventually be blocked by the elastic fixing sheet, so that after the collecting assembly composed of the collecting ring sheet and the elastic fixing sheet is removed, the excess material will no longer roll into the holding pot 3, thus avoiding the problem that the prior art requires at least two staff members to cooperate in operating the device, which is very inconvenient and the excess material is easy to roll into the holding pot 3;

[0074] In order to prevent hollowing of the measured material in the metering barrel 4 and to avoid the subsequent hollowing affecting the measurement data, the staff also needs to use a stirring rod to tamp the measured material (in order to ensure that the measured material will not be stratified by water and concrete materials under the operation of the mixing machine, affecting subsequent tests, the existing technology is to tamp manually). However, when tamping the measured material, on the one hand, the effect of tamping is very random each time, and it cannot be guaranteed that each tamping can achieve the effect of eliminating all hollows.

[0075] On the other hand, in actual operation, in order to make the metering barrel 4 be taken out more smoothly, the lower part of the metering barrel 4 has a larger space than the upper part, and when the measured material enters the metering barrel 4, it is restricted by the upper opening of the metering barrel 4, and each time the measured material is added, it is Fig.15 The initial addition state shown in FIG. 1 makes it easier to measure the material at the bottom of the metering barrel 4. Fig.16 Example empty pile shown;

[0076] Therefore, the device is also provided with a stirring assembly. Since the handle is connected to the metering barrel 4 through a fixed seat, and the fixed seat is provided with a torsion spring, when the fixed hook 206 hooks the handle, it is also pulled by the restoring elastic force of the torsion spring of the tightening wheel 203, and the torsion force of the torsion spring of the fixed seat is smaller than the torsion spring of the tightening wheel 203. At this time, the handle will be driven by the fixed hook 206 to rotate downward, and the rotation of the handle drives the connected first inclined noodle to rotate. When the first inclined noodle rotates, it will squeeze the second inclined noodle. The second inclined noodle squeezes the connected elastic fixing piece, and the elastic fixing piece generates a restoring elastic force for resetting the second inclined noodle. The second inclined noodle is squeezed and connected, and a plurality of inserts move toward the center direction of the metering barrel 4. The inserts are moved from Fig.15 Transformation Fig.16 state, and the insertion bar is inserted into the example empty pile.

[0077] When the two fixing hooks 206 hook the handles at the corresponding positions, and the fixing rope 205 is stuck by the limit block 214 and the clamping block 204 at the corresponding positions, and the measuring material fills the measuring barrel 4, the staff will complete the insertion and tamping of the measuring material.

[0078] At this time, the slide rail 201 starts to work, driving all the connected sliders 202 to start rotating around the center of the slide rail 201. Each slider 202 drives the corresponding position of the tightening wheel 203, the block 204, the fixing rope 205 and the fixing hook 206 to rotate in turn.

[0079] Each telescopic member 213 is connected to the rotating ring 232, so when the limit block 214 is driven by the clamping block 204 to rotate, the telescopic member 213 can also rotate through the rotating ring 232, so that the telescopic member 213 will not restrict the limit block 214 and the clamping block 204 from working together to clamp the fixing rope 205;

[0080] The left and right two fixed hooks 206 drive the metering bucket 4 to rotate through the hooked handles. When the metering bucket 4 rotates, it also drives the second inclined strips connected to it to rotate. In this way, a plurality of second inclined strips can move the sample empty pile in the sample soil pile, so that the materials around the sample empty pile can be moved and filled into the sample empty pile. After that, the staff compacts the moved sample soil pile according to the actual situation. In this way, the problem that the material measured at the lower part of the metering bucket 4 in the prior art is more likely to be in the sample empty pile is avoided, and the tamping work is still performed by the staff, and there will be no stratification of the measured materials.

[0081] Furthermore, since the collecting assembly is fixed to the metering barrel 4 by an elastic fixing sheet, a great deal of strength is required when installing or pulling out the collecting assembly. If the staff uses too much force when pulling out the collecting assembly, the excess material on the collecting assembly will be thrown away, which greatly affects the convenience of the device.

[0082] Therefore, the device is also provided with a rotation limiting component, and the elastic fixing sheet is provided with an air cavity. When the collecting component is sleeved on the metering barrel 4, the rotation limiting component is inserted into the gap between the clamping strip and the metering barrel 4 at the corresponding position. Under the squeezing of the clamping strip, the opening of the opening spring sheet begins to close, and then the opening spring sheet begins to squeeze the airbag. The airbag is squeezed, and the internal air enters the air cavity through the flexible tube. At this time, the air volume in the air cavity increases, squeezing the elastic fixing sheet, so that the elastic fixing sheet expands, so that the elastic fixing sheet can be tightly sleeved with the metering barrel 4. Later, when the collecting component needs to be removed from the metering barrel 4, the rotation limiting component is pulled out, and the opening spring sheet can be reset. At this time, the airbag can suck the air back again;

[0083] Furthermore, before the measured material enters the metering barrel 4, the handle needs to be hooked by the fixing hook 206 to stabilize the metering barrel 4. However, under the hooking of the fixing hook 206, the insert will enter the metering barrel 4 before the measured material enters the metering barrel 4. Fig.16 state, so the insertion strip will affect the measurement of material entering the metering barrel 4,

[0084] Therefore, when the rotation limiting component is inserted into the gap between the card strip and the metering barrel 4, the rotation limiting component also limits the handle through the card strip, so that the handle cannot be rotated downward, and the insertion strip cannot enter the metering barrel 4. The collecting component will not be removed until it is in the metering barrel 4. Specifically, the rotation limiting component will not be removed until it is in the metering barrel 4. In this way, with the cooperation of the rotation limiting component, the problem of the insertion strip affecting the measured material entering the metering barrel 4 will not occur.

[0085] Example 4

[0086] On the basis of Example 3, Figure 17-Figure 18 As shown,

[0087] It includes a fixing frame, a buckle and a guide groove; the fixing rod 9 is fixedly connected to the fixing frame, and the fixing rod 9 passes through the fixing frame; the fixing frame is fixedly connected to a plurality of buckles, and the number of buckles corresponds to the number of fixing hooks 206; the holding pot 3 has a plurality of guide grooves arranged in a circular array, and the number and position of the guide grooves correspond to the number and position of the fixing hooks 206.

[0088] In the prior art, in order for the glass pressing plate 10 to smoothly enter the containing pot 3, the diameter of the glass pressing plate 10 is set to the inner annular diameter of the containing pot 3. However, when the glass pressing plate 10 falls toward the collapsed soil pile, the glass pressing plate 10 is connected to the fixing rod 9. The vibration generated by the vibration table 1 will inevitably vibrate the fixing rod 9, and the fixing rod 9 will cause the glass pressing plate 10 to shake when it falls. This results in that when the glass pressing plate 10 contacts the collapsed soil pile and falls, it sometimes cannot accurately fall into the containing pot 3.

[0089] Therefore, before the worker takes away the metering bucket 4 by the handle, the measured material also forms a sample soil pile, and the worker holds the observation piece composed of the fixing rod 9, the hollow fixing box 93 and the glass pressure plate 10,

[0090] The staff pulls the four fixing hooks 206 in sequence, and passes each fixing hook 206 through the guide slot at the corresponding position, and each fixing hook 206 also drives the corresponding fixing rope 205 to pass through the corresponding guide slot, and then hangs each fixing hook 206 on the corresponding buckle.

[0091] In this way, all the fixing ropes 205 and the fixing hooks 206 are in the form of Fig.17 In this way, all the fixing ropes 205 form a guide line to guide the observation piece, so that when the glass pressure plate 10 contacts and falls with the collapsed soil pile, it can accurately fall into the containing pot 3, making the device more convenient to use.

[0092] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes may be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
