Description

Technical Field

[0001] The invention belongs to the technical field of concrete slump testing, and in particular relates to a concrete rheological property testing device. Background Art

[0002] The rheological properties of concrete refer to the fluidity of concrete without vibration, and slump is one of its important evaluation indicators.

[0003] The existing concrete slump test is to fill the conical slump cone with concrete, and then separate the slump cone from the concrete without touching the concrete. Finally, after the concrete pile is left to stand for a certain period of time, the height of its highest point is detected, recorded as H1, and the height between the top of the slump cone and H2 is subtracted. The absolute value of the difference is the slump value.

[0004] Then, in general, the slump cone is separated from the concrete by manual vertical lifting. Its stability is low when it rises, and it is easy to touch the concrete, which affects the fluidity of the concrete pile. Therefore, it is necessary to use mechanized means to separate the slump cone from the concrete pile. Summary of the invention

[0005] The concrete rheological property testing device of the present invention is used to solve the problems mentioned in the background technology.

[0006] The concrete rheological properties testing device of the present invention comprises a frame rod, which can be placed on the ground, and a bottom plate is fixedly connected to the frame rod, or a lifting assembly is provided on the frame rod, and a bottom plate is provided on the lifting assembly, and the bottom plate can be arranged horizontally; and also comprises two separation cylinder assemblies, which are symmetrically arranged along a plane P, and the plane P is arranged vertically; the separation cylinder assembly comprises: Slump cone unit: the slump cone units of two separate cone assemblies can be assembled into a complete slump cone. The slump cone is a conical cylinder, and the interior of the slump cone can be filled with concrete. The lower surface of the slump cone contacts the upper surface of the bottom plate. A first cylinder, the non-telescopic end of which is fixed to the frame rod, and the axis of the telescopic end of the first cylinder is perpendicular to the plane P; a fixed rod fixed to the non-telescopic end of the first cylinder; Rod 1, rod 2, and rod 3 are fixedly connected in sequence, and rod 1 is fixedly connected to the fixed rod; rod 2 is horizontally arranged, and the length direction of rod 2 is parallel to the axis direction of the telescopic end of the first cylinder; the direction of the telescopic end of the first cylinder is assumed to be the Y direction, and when viewed from a top view, the direction perpendicular to the Y direction is assumed to be the X direction; when viewed from the X direction, the upper end of rod 3 is connected to the end of rod 2 away from rod 1, and the end of rod 2 connected to rod 1 is assumed to be point A, and the other end is assumed to be point O, and the end of rod 3 away from rod 2 is assumed to be point B, then ∠AOB is an obtuse angle; A driving rod is fixed to the telescopic end of the first cylinder, and the axis of the driving rod is arranged in the vertical direction; The support frame is sleeved on the driving rod and can move vertically relative to the driving rod; A roller is arranged on the support frame, and the roller abuts against the inner wall of the second rod or the third rod; A first spring, the lower end of which is fixedly connected to the support frame, the upper end of which is fixedly connected to the driving rod, and the first spring is always in an extended state; A slide groove is provided on the support frame, and the length direction of the slide groove is along the Y direction; A slide bar is movably mounted in the slide slot and can move relative to the slide slot along the Y direction; The second spring is in the slide groove, one end of which is connected to the slide rod and the other end of which is connected to the slide groove. When the two slump cone units are not assembled into a slump cone, the second spring is in a natural state. When the two slump cone units are assembled into a slump cone, the second spring is in a compressed state.

[0007] The first cylinder is used as a power to separate the two slump cone units. Before the two slump cone units are separated horizontally, the tension generated by the first spring is used to move the roller along the inner wall of the third rod, so that the two slump cone units move upward, so that the concrete can be separated from the slump cone. Then, the roller is moved along the inner wall of the second rod to separate the two slump cone units horizontally. The separation process is highly mechanized, avoiding the interference of concrete caused by manual participation. Through the design of the second spring, the two slump cone units are first completely raised separately, and the two slump cone units are first separated from the concrete upward. Compared with the horizontal separation first, the two slump cone units will rub against the bottom plate in the horizontal separation, thereby interfering with the concrete on the bottom plate. Moreover, the two slump cone units are first separated from the concrete vertically. Compared with the separation at other angles, the vertical separation has a better separation effect from the concrete.

[0008] Furthermore, the lifting assembly comprises: The lifting cylinder has a telescopic end axis arranged vertically, and the non-telescopic end of the lifting cylinder is fixed on the frame rod; A lifting block is fixed on the telescopic end of the lifting cylinder, and a cavity is provided in the lifting block; The non-rotating shaft end of the rotating motor is fixed in the cavity, the rotating shaft of the rotating motor extends out of the cavity, and the rotating shaft of the rotating motor is along the Y direction; the rotating shaft of the rotating motor is fixedly connected to the bottom plate, or a quick-release structure is provided on the rotating shaft of the rotating motor, and the quick-release structure is connected to the bottom plate.

[0009] The bottom plate can be lowered to leave a certain space between the two slump cone units. The space left is convenient for test personnel to clean the surface of the bottom plate and remove the residue on the bottom plate, so that the next test will not be affected by the residue.

[0010] Furthermore, the quick-release structure comprises: A quick release plate, fixed on the rotating shaft of the rotating motor; The insertion rod is inserted into the quick release plate. The quick release plate is provided with a through hole for the insertion rod to pass through. The length direction of the through hole is along the Y direction. The insertion rod can move relative to the quick release plate along the axis of the through hole. A mounting bracket, fixed on the quick release plate; The quick-release spring has one end fixedly connected to the mounting frame and the other end fixedly connected to the insertion rod. The quick-release spring is always in a compressed state. A socket is provided on the side of the bottom plate along the Y direction. Under the action of the quick-release spring, the insertion rod can be inserted into the corresponding socket. The end face of the insertion rod is rectangular, and the socket is adapted to the insertion rod.

[0011] The bottom plate can be replaced after use. There is no need to clean the bottom plate temporarily. Instead, it can be directly replaced with another clean bottom plate. The replaced bottom plate with concrete residue can be cleaned later. The one-time replacement bottom plate design saves more test time.

[0012] Furthermore, when the roller abuts against the inner wall of the upper end of the rod three, the second spring is just in a natural state; when the roller abuts against the inner wall of other positions of the rod three other than the upper end, the second spring is in a compressed state.

[0013] This is to enable the second spring, the slide bar and the slump cone unit to move as a whole directly when the two slump cone units are separated horizontally, without being affected by the compression stroke of the second spring. If the second spring is still in a compressed state when the roller abuts the upper end of the rod three, the rod two will be made longer to meet the purpose of horizontal opening of the two slump cone units. An excessively long rod two will affect its strength and increase the space occupied by the equipment, which is not conducive to manufacturing and use.

[0014] Furthermore, the roller can rotate, and the rotation axis of the roller is along the X direction.

[0015] The roller can rotate so as to reduce the friction between the roller and the rods 2 and 3 as much as possible.

[0016] Furthermore, the rotating motor is a servo motor.

[0017] The rotation angle can be accurately controlled and the servo motor can be self-locked after power failure. The rotating motor can flip the bottom plate so that it is no longer horizontal. The non-horizontal bottom plate is easy to be cleaned by the test personnel. For example, turning the upper surface of the bottom plate to face the face of the person can make it easier for the test personnel to clean the concrete residue on the bottom plate. The servo motor can perfectly reset the bottom plate after the bottom plate rotates a certain angle, ensuring that the bottom plate is still horizontal during the next test.

[0018] Beneficial Effects

[0019] By setting the rod two, the rod three and the first spring, the concrete and the two slump cone units can be separated mechanically, and the two slump cone units can be moved vertically first and then horizontally, thereby avoiding the interference of friction vibration between the lower end of the slump cone unit and the bottom plate surface on the concrete when the two slump cone units move horizontally first.

[0020] A lifting assembly and a rotating motor are provided to allow the bottom plate to be displaced and rotated to a certain extent, so that the bottom plate is displaced or rotated to a state that is convenient for the tester to clean the concrete residue, thereby facilitating the cleaning of the residue on the bottom plate and reducing the interference of the concrete residue on each test during multiple tests.

[0021] The bottom plate can be quickly replaced through the quick-release structure. It can be used one by one during multiple tests, and the replaced bottom plate can be cleaned. It is convenient for cleaning and can also save test time, so that the test and cleaning of the bottom plate can be carried out simultaneously by two people.

[0022] Only relying on the first cylinder, the second rod and the third rod, the two slump cone units can be moved vertically first and then horizontally. There is no need for two cylinders to move the slump cone units vertically first and then horizontally respectively, thus simplifying the entire device.

[0023] After the two slump cone units are merged, the two slump cone units continuously compress the second spring. The advantage of this design is that the extension stroke of the first cylinder can be over-controlled, so that the deformation of the second spring can adapt to the excessive extension of the first cylinder. The excessive extension can ensure that the two slump cone units are tightly attached and sealed. If there is no second spring, the only way to make the two slump cone units fit together is to accurately set the extension of the two first cylinders to ensure that the two slump cone units are just in contact and sealed. For the control of the first cylinder, because it is difficult to accurately control the extension of the first cylinder, the sealing of the two slump cone units cannot be guaranteed, and there is often a gap at the millimeter level, and the sealing is poor. Therefore, the design of the second spring cleverly avoids the problem of poor sealing. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Example 1: See Figure 1 The concrete rheological properties testing device comprises four frame rods 1, the axes of the four frame rods 1 are all arranged vertically, and the four frame rods 1 enable the entire testing device to be placed on the ground. In a top view, the four frame rods 1 enclose a rectangular area, and the rectangular area enclosed by the four frame rods 1 is recorded as area A. A bottom plate 2 is provided in area A, and the edges of the bottom plate 2 are welded and fixed to the four frame rods 1. The bottom plate 2 is arranged horizontally.

[0028] From a top view, let the direction of one side of the bottom plate 2 be the X direction, let the midline of the bottom plate 2 in the X direction be line L, and the surface passing through line L and along the vertical direction be surface P; let the direction of the adjacent side of the bottom plate 2 be the Y direction, let the midline of the bottom plate 2 in the Y direction be line M, and the surface passing through line M and along the vertical direction be surface N.

[0029] Two sets of separation cylinder assemblies are arranged on the four frame rods 1, and the two sets of separation cylinder assemblies are symmetrically arranged along the plane P. The separation cylinder assembly includes: The slump cone unit 3, the slump cone units 3 of the two separation cone assemblies can be assembled together into a complete slump cone. The shape of the complete slump cone is a conical cylinder, and the bottom surface of the side with a larger area is the lower bottom surface of the conical cylinder. When the two slump cone units 3 are assembled into a slump cone, the lower bottom surface of the slump cone is in contact with the upper surface of the base plate 2, and concrete can be poured into the interior of the slump cone from the upper end opening of the slump cone. The concrete is in contact with the upper surface of the base plate 2. At this time, concrete can be filled into the slump cone for a slump value test. After filling, the concrete is separated from the slump cone, and the height of the highest point of the concrete pile is detected after it is still for a certain period of time, which is recorded as H1, and the difference is made from the height H2 between the tops of the slump cones. The absolute value of the difference is the slump value.

[0030] See Figure 1 and Figure 2 , two driving components are symmetrically arranged along plane N. The driving component includes: a first cylinder 4, whose axis is along the Y direction. The non-retractable end of the first cylinder 4 is fixedly installed on the frame rod 1 through a connecting plate. The non-retractable end of the first cylinder 4 is welded to the connecting plate, and the connecting plate is also welded to the frame rod 1. A fixing rod 5 is welded and fixed to the non-rotating shaft end of the first cylinder 4. Looking along the X direction, the shape of the fixing rod 5 is an inverted "L" shape. A limiting frame, the limiting frame is composed of three rods connected in sequence. The three rods are respectively denoted as rod one 6, rod two 7, and rod three 8; Figure 2 Looking from a perspective, the lower end of rod one 6 is welded to the right end of the fixing rod 5, the left end of rod two 7 is welded to the upper end of rod one 6, the right end of rod two is welded to the upper end of rod three 8, and the lower end of rod three 8 is not connected to other components. In this embodiment, looking along the X direction, the overall shape of rod one 6, rod two 7, and rod three 8 is the outer frame of an isosceles trapezoid, and the outer shell of this isosceles trapezoid does not have a lower bottom rod with a longer length. Rod one 6 and rod three 8 respectively form the two waists of the isosceles trapezoid, and rod two 7 forms the shorter upper base of the isosceles trapezoid. The length direction of rod two 7 is parallel to the Y direction. In other embodiments, rod one, rod two, and rod three can be a non-isosceles trapezoid structure, as long as the following conditions are met: the upper end of rod three is welded to the right end of rod two. Looking along the X direction, let the left end of rod two be point A, let the right end of rod two be point O, let the lower end of rod three be point B, and ∠AOB is an obtuse angle.

[0031] A driving rod 9 is welded to the retractable ends of the two first cylinders 4 through a base at the same time. The axis of the driving rod 9 is arranged vertically.

[0032] A support frame 10. In this embodiment, looking from a top view, the support frame 10 is an axisymmetric figure, the support frame 10 is symmetrically arranged along plane N. Looking from a top view, the shape of the support frame 10 is a "匚" shape. The support frame 10 is sleeved on the driving rod 9, the support frame 10 is movably clamped on the driving rod 9, and the support frame 10 can move vertically relative to the driving rod 9.

[0033] Two groups of linkage components are symmetrically arranged along the surface N. The linkage component assembly includes: a roller 11, which is connected to the support frame 10 by means of an axis rotation, and the axis of the roller 11 is along the X direction. The roller 11 can abut against the inner wall of one of the rods 2 7 and the rod 3 8. The first spring 12 has a telescopic direction along the vertical direction; the lower end of the first spring 12 is welded to the upper surface of the support frame 10, and the upper end is welded to the driving rod 9. The first spring 12 is always in an extended state, and the first spring 12 will generate an upward pulling force on the support frame 10; under the pulling force of the first spring 12, the roller 11 always maintains abutment against the inner wall of one of the rods 2 7 and the rod 3 8. The slide groove 13 is opened on the support frame 10, and the length direction of the slide groove 13 is along the Y direction. The slide rod 14 is movably clamped in the slide groove 13, and the slide rod 14 can move along the Y direction. The slide rod 14 is welded and fixed to the slump cone unit 3. The second spring 15 is in the chute 13, and the expansion and contraction direction of the second spring 15 is along the Y direction. One end of the second spring 15 is welded and fixed to the chute 13, and the other end is welded and fixed to the slide rod 14. Before the two slump cone units 3 form a complete slump cone, the second spring 15 is in a natural state; after the two slump cone units 3 form a slump cone, the second spring 15 is compressed along the Y direction in the chute 13.

[0034] In this embodiment, the use process of the testing device is as follows: Assuming that two slump cone units 3 are assembled into a complete slump cone, at this time, the roller 11 abuts against the inner wall of the lower end of the rod 3 8, that is, Figure 2 State. Assume this time as the initial state. Separating the two slump units 3 is divided into two steps: The first step is to separate the slump cone from the concrete vertically.

[0035] The specific actions are as follows: Starting from the initial state, looking at the left separation barrel assembly, the two first cylinders 4 are shortened at the same time, and the driving rod 9, the support frame 10, and the roller 11 move leftward along the Y direction as a whole. At the same time, since the first spring 12 exerts an upward pulling force on the support frame 10, the support frame 10 and the roller 11 move upward as a whole; that is, the support frame 10 and the roller 11 move both leftward and upward as a whole, that is, along the length trajectory of the rod three 8, from bottom to top.

[0036] When the driving rod 9, the support frame 10, and the roller 11 move to the left along the Y direction as a whole, the second spring 15 gradually extends from the compressed state. During this process, the two slump cone units 3 are still not separated by the elastic force of the second spring, and the slide bar 14 moves in the slide groove 13 along the Y direction. However, since the support frame 10 and the roller 11 also move upward as a whole, the support frame 10, the roller 11, the second spring 15 and the slide bar 14, and the slump cone unit 3 move upward as a whole. From the perspective of the slump cone, the slump cone only moves upward relative to the concrete, that is, the slump cone is separated vertically from the concrete. The two first cylinders 4 in the right separation cylinder assembly are also shortened, and the actions of other components are similar to the above content and will not be repeated.

[0037] When roller 11 moves to the upper end inner wall of rod 3 8, second spring 15 just returns to natural state, and now slump cone moves vertically to the highest point. At this moment, two slump cone units 3 are still not horizontally separated from each other.

[0038] The second step is to separate the two slump cone units 3 horizontally.

[0039] The specific actions are as follows: In the left separation cylinder assembly, the two first cylinders 4 continue to shorten at the same time, driving the rod 9, the support frame 10, and the roller 11 as a whole to move to the left along the Y direction, and the roller 11 contacts the inner wall of the rod 2 7. However, since the rod 2 7 is set horizontally, the pulling force of the first spring 12 on the support frame 10 cannot make the support frame 10 and the roller 11 move upward as a whole. In addition, since the second spring 15 has returned to its natural state, the support frame 10 and the roller 11 move to the left as a whole, which will cause the support frame 10, the roller 11, the second spring 15, the slide bar 14, and the slump cone unit 3 to move to the left as a whole. The two first cylinders 4 in the other separation cylinder assembly are also shortened, and the actions of other components are similar to the above content, which will not be repeated. Finally, the two slump cone units 3 are horizontally separated in opposite directions.

[0040] Example 2: See Figure 3 , the concrete rheological properties testing device is different from the embodiment 1 in that, in this embodiment, the bottom plate 2 is not welded to the frame rod 1. In this embodiment, the bottom plate 2 can move vertically. The frame rod 1 is provided with two sets of lifting components for vertically moving the bottom plate 2. The two sets of lifting components are symmetrically arranged along the plane P.

[0041] The lifting assembly includes: Lifting cylinder 16, in this embodiment, a set of lifting components has two lifting cylinders, the axis is arranged vertically, the non-telescopic end of the lifting cylinder 16 is welded to the frame rod 1 through a support, the non-telescopic end of the lifting cylinder 16 is welded to the support, and the support is welded to the frame rod 1. The telescopic end of the lifting cylinder 16 faces downward.

[0042] The lifting block 17 is welded to the non-telescopic ends of the two lifting cylinders 16 of the same lifting assembly, and can be simultaneously extended and retracted with the telescopic ends of the two lifting cylinders 16 in the lifting group to achieve the lifting of the lifting block 17. A cavity is provided inside the lifting block 17.

[0043] The rotating motor 18 is in the cavity. The non-rotating shaft end of the rotating motor 18 is installed in the cavity by means of bolts. The cavity is designed to be in a non-closed state, which is convenient for the rotating motor 18 to be installed in the cavity. The rotating shaft of the rotating motor 18 passes through the lifting block 17. The lifting block 17 is provided with a hole for the rotating shaft of the rotating motor 18 to pass through. The rotating shaft of the rotating motor 18 is along the X direction. The rotating motor 18 adopts a servo motor, which can accurately control the rotation angle of its rotating shaft and can be locked after stopping. The rotating shafts of the two rotating motors 18 are respectively welded and fixed to the two side surfaces of the base plate 2 along the Y direction. The two rotating motors 18 in the two lifting assemblies rotate in opposite directions, and the rotation angle and angular velocity remain consistent.

[0044] When doing the slump value test, the base plate is kept horizontal, and the lifting cylinder 16 keeps the lower surface of the slump cone in contact with the upper surface of the base plate. After completing the slump value test, the base plate can be flipped to a certain angle by using two rotating motors 18 while the lifting cylinder 16 is lowered, so that the test personnel can wipe the concrete remaining on the upper surface of the base plate to avoid the concrete of the previous test from affecting the results of the next test. The lifting cylinder 16 and the rotating motor 18 mainly serve the purpose of facilitating the cleaning of the base plate. The rotating motor used is a servo motor, which can accurately control its rotation angle and keep the base plate horizontal when the base plate is reset after flipping to a certain angle.

[0045] Example 3: See Figure 4 The concrete rheological properties testing device is different from the frame rod of Example 2 in that, in this embodiment, the bottom plate is no longer directly fixed to the rotating shaft of the rotating motor by welding, but is indirectly installed on the rotating shaft of the rotating motor by a quick release structure. Because there are two rotating motors, and they are symmetrically arranged along the surface P, there are also two quick release assemblies, and they are symmetrically arranged along the surface P. The quick release structure includes: The quick-release plate 19 is welded and fixed on the rotating shaft of the rotating motor.

[0046] The insertion rod 20 is inserted through the quick release plate 19. The quick release plate 19 is provided with a through hole 21 for the insertion rod 20 to pass through. The length direction of the through hole 21 is along the Y direction. The insertion rod 20 can move relative to the quick release plate 19 along the axis of the through hole 21. In this embodiment, the insertion rod 20 is T-shaped when viewed along the X direction. The insertion rod 20 is composed of a rod portion and a cap portion. The rod portion is inserted through the aforementioned through hole 21, and the cap portion abuts against the left surface of the quick release plate 19.

[0047] The mounting bracket 22 is welded and fixed to the left surface of the quick-release plate 19. When viewed from the top view, the mounting bracket 22 is in an inverted U shape.

[0048] The quick-release spring 23 has one end welded and fixed to the mounting bracket 22 and the other end welded and fixed to the cap portion of the insertion rod 20. The quick-release spring 23 is always in a compressed state. Only under the elastic force of the quick-release spring 23, the cap portion of the insertion rod 20 abuts against the left surface of the quick-release plate 19, and the right end of the insertion rod 20 extends out of the through hole 21; A jack 24 is provided on the side surface of the bottom plate along the Y direction. Under the action of the quick-release spring 23, the right end of the insertion rod 20 can be inserted into the corresponding jack 24. In this embodiment, the end face shape of the insertion rod 20 is rectangular, and the shape of the jack 24 is adapted thereto, ensuring that the bottom plate will not rotate around the midline of the insertion rod 20 along the Y direction after the insertion rod 20 is inserted into the jack 24.

[0049] Taking the above ideal embodiment based on the present invention as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of the present invention. The technical scope of the present invention is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
